Missing values don't affect the structure of the data set.2.How many program steps are executed when the program below is processed?data user.tables;infile jobs;input date name $ job $;run;proc sort data=user.tables;by name;run;proc print data=user.tables;run;a.threeb.fourc.fived.sixCorrect answer:aWhen it encounters a DATA, PROC, or RUN statement, SAS stops reading statements andexecutes the previous step in the program. The program above contains one DATA step and two PROC steps, for a total of three program steps.3.What type of variable is the variable AcctNum in the data set below?a.numericb.characterc.can be either character or numericd.can't tell from the data shownCorrect answer:bIt must be a character variable, because the values contain letters and underscores, which are not valid characters for numeric values.4.What type of variable is the variable Wear in the data set below?a.numericb.characterc.can be either character or numericd.can't tell from the data shownCorrect answer:aIt must be a numeric variable, because the missing value is indicated by a period rather than by a blank.5.Which of the following variable names is valid?a.4BirthDateb.$Costc._Items_d.Tax-RateCorrect answer:cVariable names follow the same rules as SAS data set names. They can be 1 to 32 characters long, must begin with a letter (A–Z, either uppercase or lowercase) or an underscore, and can continue with any combination of numbers, letters, or underscores.6.Which of the following files is a permanent SAS file?a.Sashelp.PrdSaleb.Sasuser.MySalesc.Profits.Quarter1d.all of the aboveCorrect answer:dTo store a file permanently in a SAS data library, you assign it a libref other than the default Work. For example, by assigning the libref Profits to a SAS data library, you specify that files within the library are to be stored until you delete them. Therefore, SAS files in the Sashelp and Sasuser libraries are permanent files.7.In a DATA step, how can you reference a temporary SAS data set named Forecast?a.Forecastb.Work.Forecastc.Sales.Forecast (after assigning the libref Sales)d.only a and b aboveCorrect answer:dTo reference a temporary SAS file in a DATA step or PROC step, you can specify the one-level name of the file (for example, Forecast) or the two-level name using the libref Work (for example, Work.Forecast).8.What is the default length for the numeric variable Balance?a. 5b. 6c.7d.8Correct answer:dThe numeric variable Balance has a default length of 8. Numeric values (no matter how many digits they contain) are stored in 8 bytes of storage unless you specify a different length.9.How many statements does the following SAS program contain?proc print data=new.prodsalelabel double;var state day price1 price2; where state='NC';label state='Name of State';run;a.threeb.fourc.fived.sixCorrect answer:cThe five statements are•PROC PRINT statement (two lines long)•VAR statement•WHERE statement (on the same line as the VAR statement)•LABEL statement•RUN statement (on the same line as the LABEL statement).10.What is a SAS data library?a. a collection of SAS files, such as SAS data sets and catalogsb.in some operating environments, a physical collection of SAS filesc.in some operating environments, a logically related collection of SAS filesd.all of the aboveCorrect answer:dEvery SAS file is stored in a SAS data library, which is a collection of SAS files, such as SAS data sets and catalogs. In some operating environments, a SAS data library is a physical collection of files. In others, the files are only logically related. In the Windows and UNIX environments, a SAS data library is typically a group of SAS files in the same folder or directory.Chapter 2: Referencing Files and Setting Options1.If you submit the following program, how does the output look?options pagesize=55 nonumber;proc tabulate data=clinic.admit;class actlevel;var age height weight;table actlevel,(age height weight)*mean;run;options linesize=80;proc means data=clinic.heart min max maxdec=1;var arterial heart cardiac urinary;class survive sex;run;a.The PROC MEANS output has a print line width of 80 characters, but the PROCTABULATE output has no print line width.b.The PROC TABULATE output has no page numbers, but the PROC MEANS outputhas page numbers.c.Each page of output from both PROC steps is 55 lines long and has no page numbers,and the PROC MEANS output has a print line width of 80 characters.d.The date does not appear on output from either PROC step.Correct: answer:cWhen you specify a system option, it remains in effect until you change the option or end your SAS session, so both PROC steps generate output that is printed 55 lines per page with no page numbers. If you don't specify a system option, SAS uses the default value for that system option.2.In order for the date values 05May1955 and 04Mar2046 to be read correctly, what value mustthe YEARCUTOFF= option have?a. a value between 1947 and 1954, inclusiveb.1955 or higherc.1946 or higherd.any valueCorrect answer:dAs long as you specify an informat with the correct field width for reading the entire date value, the YEARCUTOFF= option doesn't affect date values that have four-digit years.3.When you specify an engine for a library, you are always specifyinga.the file format for files that are stored in the library.b.the version of SAS that you are using.c.access to other software vendors' files.d.instructions for creating temporary SAS files.Correct answer:aA SAS engine is a set of internal instructions that SAS uses for writing to and reading from files in a SAS library. Each engine specifies the file format for files that are stored in the library, which in turn enables SAS to access files with a particular format. Some engines access SAS files, and other engines support access to other vendors' files.4.Which statement prints a summary of all the files stored in the library named Area51?a.proc contents data=area51._all_ nods;b.proc contents data=area51 _all_ nods;c.proc contents data=area51 _all_ noobs;d.proc contents data=area51 _all_.nods;Correct answer:aTo print a summary of library contents with the CONTENTS procedure, use a period to append the _ALL_ option to the libref. Adding the NODS option suppresses detailed information about the files.5.The following PROC PRINT output was created immediately after PROC TABULATEoutput. Which SAS system options were specified when the report was created?a.OBS=, DATE, and NONUMBERb.PAGENO=1, and DATEc.NUMBER and DATE onlyd.none of the aboveCorrect answer:bClearly, the DATE and PAGENO= options are specified. Because the page number on the output is 1, even though PROC TABULATE output was just produced. If you don't specify PAGENO=, all output in the Output window is numbered sequentially throughout your SAS session.6.Which of the following programs correctly references a SAS data set named SalesAnalysisthat is stored in a permanent SAS library?a.data saleslibrary.salesanalysis;set mydata.quarter1sales;if sales>100000;run;b.data mysales.totals;set sales_99.salesanalysis;if totalsales>50000;run;c.proc print data=salesanalysis.quarter1;var sales salesrep month;run;d.proc freq data=1999data.salesanalysis;tables quarter*sales; run;Correct answer:bLibrefs must be 1 to 8 characters long, must begin with a letter or underscore, and can contain only letters, numbers, or underscores. After you assign a libref, you specify it as the first element in the two-level name for a SAS file.7.Which time span is used to interpret two-digit year values if the YEARCUTOFF= option isset to 1950?a.1950-2049b.1950-2050c.1949-2050d.1950-2000Correct answer:aThe YEARCUTOFF= option specifies which 100-year span is used to interpret two-digit year values. The default value of YEARCUTOFF= is 1920. However, you can override the default and change the value of YEARCUTOFF= to the first year of another 100-year span. If you specify YEARCUTOFF=1950, then the 100-year span will be from 1950 to 2049.8.Asssuming you are using SAS code and not special SAS windows, which one of thefollowing statements is false?a.LIBNAME statements can be stored with a SAS program to reference the SAS libraryautomatically when you submit the program.b.When you delete a libref, SAS no longer has access to the files in the library.However, the contents of the library still exist on your operating system.c.Librefs can last from one SAS session to another.d.You can access files that were created with other vendors' software by submitting aLIBNAME statement.Correct answer:cThe LIBNAME statement is global, which means that librefs remain in effect until you modify them, cancel them, or end your SAS session. Therefore, the LIBNAME statement assigns the libref for the current SAS session only. You must assign a libref before accessingSAS files that are stored in a permanent SAS data library.9.What does the following statement do?libname osiris spss 'c:\myfiles\sasdata\data';a.defines a library called Spss using the OSIRIS engineb.defines a library called Osiris using the SPSS enginec.defines two libraries called Osiris and Spss using the default engined.defines the default library using the OSIRIS and SPSS enginesCorrect answer:bIn the LIBNAME statement, you specify the library name before the engine name. Both are followed by the path.10.What does the following OPTIONS statement do?options pagesize=15 nodate;a.suppresses the date and limits the page size of the logb.suppresses the date and limits the vertical page size for text outputc.suppresses the date and limits the vertical page size for text and HTML outputd.suppresses the date and limits the horizontal page size for text outputCorrect answer:bThese options affect the format of listing output only. NODATE suppresses the date and PAGESIZE= determines the number of rows to print on the page.Chapter 3: Editing and Debugging SAS Programs Answer Key1.As you write and edit SAS programs it's a good idea toa.begin DATA and PROC steps in column one.b.indent statements within a step.c.begin RUN statements in column one.d.all of the aboveCorrect answer:dAlthough you can write SAS statements in almost any format, a consistent layout enhances readability and enables you to understand the program's purpose. It's a good idea to begin DATA and PROC steps in column one, to indent statements within a step, to begin RUN statements in column one, and to include a RUN statement after every DATA step or PROC step.2.What usually happens when an error is detected?a.SAS continues processing the step.b.SAS continues to process the step, and the log displays messages about the error.c.SAS stops processing the step in which the error occurred, and the log displaysmessages about the error.d.SAS stops processing the step in which the error occurred, and the program outputdisplays messages about the error.Correct answer:cSyntax errors generally cause SAS to stop processing the step in which the error occurred. When a program that contains an error is submitted, messages regarding the problem also appear in the SAS log. When a syntax error is detected, the SAS log displays the word ERROR, identifies the possible location of the error, and gives an explanation of the error.3. A syntax error occurs whena.some data values are not appropriate for the SAS statements that are specified in aprogram.b.the form of the elements in a SAS statement is correct, but the elements are not validfor that usage.c.program statements do not conform to the rules of the SAS language.d.none of the aboveCorrect canswer:Syntax errors are common types of errors. Some SAS system options, features of the Editorwindow, and the DATA step debugger can help you identify syntax errors. Other types oferrors include data errors, semantic errors, and execution-time errors.4.How can you tell whether you have specified an invalid option in a SAS program?a. A log message indicates an error in a statement that seems to be valid.b. A log message indicates that an option is not valid or not recognized.c.The message "PROC running" or "DATA step running" appears at the top of theactive window.d.You can't tell until you view the output from the program.Correct answer:bWhen you submit a SAS statement that contains an invalid option, a log message notifies you that the option is not valid or not recognized. You should recall the program, remove or replace the invalid option, check your statement syntax as needed, and resubmit the corrected program.5.Which of the following programs contains a syntax error?Correct answer:bThe DATA step contains a misspelled keyword (dat instead of data). However, this is such a common (and easily interpretable) error that SAS produces only a warning message, not an error.6.What does the following log indicate about your program?proc print data=sasuser.cargo99var origin dest cargorev;2276ERROR 22-322: Syntax error, expecting one of the following:;, (, DATA, DOUBLE, HEADING, LABEL, N, NOOBS, OBS, ROUND, ROWS, SPLIT, STYLE,UNIFORM, WIDTH.ERROR 76-322: Syntax error, statement will be ignored.11 run;a.SAS identifies a syntax error at the position of the VAR statement.b.SAS is reading VAR as an option in the PROC PRINT statement.c.SAS has stopped processing the program because of errors.d.all of the aboveCorrect answer:dBecause there is a missing semicolon at the end of the PROC PRINT statement, SAS interprets VAR as an option in PROC PRINT and finds a syntax error at that location. SAS stops processing programs when it encounters a syntax error.Chapter 4: Creating List Reports Answer Key 1.Which PROC PRINT step below creates the following output?Correct answer:cThe DATA= option specifies the data set that you are listing, and the ID statement replaces the Obs column with the specified variable. The VAR statement specifies variables and controls the order in which they appear, and the WHERE statement selects rows based on a condition. The LABEL option in the PROC PRINT statement causes the labels that are specified in the LABEL statement to be displayed.2.Which of the following PROC PRINT steps is correct if labels are not stored with thedata set?Correct aanswer:You use the DATA= option to specify the data set to be printed. The LABEL optionspecifies that variable labels appear in output instead of variable names.3.Which of the following statements selects from a data set only those observations forwhich the value of the variable Style is RANCH, SPLIT, or TWOSTORY?Correct answer:dIn the WHERE statement, the IN operator enables you to select observations based on several values. You specify values in parentheses and separate them by spaces or commas. Character values must be enclosed in quotation marks and must be in the same case as in the data set.4.If you want to sort your data and create a temporary data set named Calc to store thesorted data, which of the following steps should you submit?Correct answer:cIn a PROC SORT step, you specify the DATA= option to specify the data set to sort. The OUT= option specifies an output data set. The required BY statement specifies the variable(s) to use in sorting the data.5.Which options are used to create the following PROC PRINT output?13:27 Monday, March 22, 1999 Patient Arterial Heart Cardiac Urinary203 88 95 66 11054 83 183 95 0664 72 111 332 12210 74 97 369 0101 80 130 291 0a.the DATE system option and the LABEL option in PROC PRINTb.the DATE and NONUMBER system options and the DOUBLE and NOOBSoptions in PROC PRINTc.the DATE and NONUMBER system options and the DOUBLE option inPROC PRINTd.the DATE and NONUMBER system options and the NOOBS option in PROCPRINTCorrect answer:bThe DATE and NONUMBER system options cause the output to appear with the date but without page numbers. In the PROC PRINT step, the DOUBLE option specifies double spacing, and the NOOBS option removes the default Obs column.6.Which of the following statements can you use in a PROC PRINT step to create thisoutput?Correct answer:dYou do not need to name the variables in a VAR statement if you specify them in the SUM statement, but you can. If you choose not to name the variables in the VAR statement as well, then the SUM statement determines the order of the variables in the output.7.What happens if you submit the following program?proc sort data=clinic.diabetes;run;proc print data=clinic.diabetes;var age height weight pulse;where sex='F';run;a.The PROC PRINT step runs successfully, printing observations in their sortedorder.b.The PROC SORT step permanently sorts the input data set.c.The PROC SORT step generates errors and stops processing, but the PROCPRINT step runs successfully, printing observations in their original (unsorted)order.d.The PROC SORT step runs successfully, but the PROC PRINT step generateserrors and stops processing.Correct answer:cThe BY statement is required in PROC SORT. Without it, the PROC SORT step fails. However, the PROC PRINT step prints the original data set as requested.8.If you submit the following program, which output does it create?proc sort data=finance.loans out=work.loans;by months amount;run;proc print data=work.loans noobs; var months;sum amount payment;where months<360;run;a.b.c.d.Correct answer:aColumn totals appear at the end of the report in the same format as the values of the variables, so b is incorrect. Work.Loans is sorted by Month and Amount, so c isincorrect. The program sums both Amount and Payment, so d is incorrect.9.Choose the statement below that selects rows which•the amount is less than or equal to $5000•the account is 101-1092 or the rate equals 0.095.Correct answer:cTo ensure that the compound expression is evaluated correctly, you can use parentheses to groupaccount='101-1092' or rate eq 0.095OBS Account Amount Rate MonthsPayment1 101-1092 $22,000 10.00%60 $467.432 101-1731 $114,0009.50% 360 $958.573 101-1289 $10,000 10.50%36 $325.024 101-3144 $3,500 10.50%12 $308.525 103-1135 $8,700 10.50%24 $403.476 103-1994 $18,500 10.00%60 $393.077 103-2335 $5,000 10.50%48 $128.028 103-3864 $87,500 9.50% 360 $735.759 103-3891 $30,000 9.75% 360 $257.75For example, from the data set above, a and b above select observations 2 and 8 (those that have a rate of 0.095); c selects no observations; and d selects observations 4 and 7 (those that have an amount less than or equal to 5000).10.What does PROC PRINT display by default?a.PROC PRINT does not create a default report; you must specify the rows andcolumns to be displayed.b.PROC PRINT displays all observations and variables in the data set. If youwant an additional column for observation numbers, you can request it.c.PROC PRINT displays columns in the following order: a column forobservation numbers, all character variables, and all numeric variables.d.PROC PRINT displays all observations and variables in the data set, a columnfor observation numbers on the far left, and variables in the order in which they occur in the data set.Correct answer:dYou can remove the column for observation numbers. You can also specify the variables you want, and you can select observations according to conditions.Chapter 5: Creating SAS Data Sets from Raw Data Answer Key1.Which SAS statement associates the fileref Crime with the raw data fileC:\States\Data\Crime?a.filename crime 'c:\states\data\crime';b.filename crime c:\states\data\crime;c.fileref crime 'c:\states\data\crime';d.filename 'c:\states\data\crime' crime; Correct aanswer:Before you can read your raw data, you must reference the raw data file by creating afileref. You assign a fileref by using a FILENAME statement in the same way thatyou assign a libref by using a LIBNAME statement.2.Filerefs remain in effect untila.you change them.b.you cancel them.c.you end your SAS session.d.all of the aboveCorrect answer:dLike LIBNAME statements, FILENAME statements are global; they remain in effect until you change them, cancel them, or end your SAS session.3.Which statement identifies the name of a raw data file to be read with the filerefProducts and specifies that the DATA step read only records 1-15?a.infile products obs 15;b.infile products obs=15;c.input products obs=15;d.input products 1-15;Correct answer:bYou use an INFILE statement to specify the raw data file to be read. You can specify a fileref or an actual filename (in quotation marks). The OBS= option in the INFILE statement enables you to process only records 1 through n.4.Which of the following programs correctly writes the observations from the data setbelow to a raw data file?Correct answer:dThe keyword _NULL_ in the DATA statement enables you to use the power of the DATA step without actually creating a SAS data set. You use the FILE and PUT statements to write out the observations from a SAS data set to a raw data file. The FILE statement specifies the raw data file and the PUT statement describes the lines towrite to the raw data file. The filename and location that are specified in the FILE statement must be enclosed in quotation marks.5.Which raw data file can be read using column input?a.b.c.d.all of the aboveCorrect answer:bColumn input is appropriate only in some situations. When you use column input, your data must be standard character or numeric values, and they must be in fixed fields. That is, values for a particular variable must be in the same location in all records.6.Which program creates the output shown below?Correct answer:aThe INPUT statement creates a variable using the name that you assign to each field. Therefore, when you write an INPUT statement, you need to specify the variable names exactly as you want them to appear in the SAS data set.7.Which statement correctly reads the fields in the following order: StockNumber,Price, Item, Finish, Style?Field Name Start Column End Column Data TypeStockNumber 1 3 characterFinish 5 9 characterStyle 11 18 characterItem 20 24 characterPrice 27 32 numericCorrec t answer:bYou can use column input to read fields in any order. You must specify the variable name to be created, identify character values with a $, and name the correct starting column and ending column for each field.8.Which statement correctly re-defines the values of the variable Income as 100percent higher?a.income=income*1.00;b.income=income+(income*2.00);c.income=income*2;d.income=*2;Correct answer:cTo re-define the values of the variable Income in an Assignment statement, you specify the variable name on the left side of the equal sign and an appropriate expression including the variable name on the right side of the equal sign.9.Which program correctly reads instream data?a.data finance.newloan;input datalines;if country='JAPAN';MonthAvg=amount/12;1998 US CARS 194324.121998 US TRUCKS 142290.301998 CANADA CARS 10483.441998 CANADA TRUCKS 93543.641998 MEXICO CARS 22500.571998 MEXICO TRUCKS 10098.881998 JAPAN CARS 15066.431998 JAPAN TRUCKS 40700.34;b.data finance.newloan;input Year 1-4 Country $ 6-11Vehicle $ 13-18 Amount 20-28;if country='JAPAN';MonthAvg=amount/12;datalines;run;c.data finance.newloan;input Year 1-4 Country 6-11Vehicle 13-18 Amount 20-28;if country='JAPAN';MonthAvg=amount/12;datalines;1998 US CARS 194324.121998 US TRUCKS 142290.301998 CANADA CARS 10483.441998 CANADA TRUCKS 93543.641998 MEXICO CARS 22500.571998 MEXICO TRUCKS 10098.881998 JAPAN CARS 15066.431998 JAPAN TRUCKS 40700.34;d.data finance.newloan;input Year 1-4 Country $ 6-11Vehicle $ 13-18 Amount 20-28;if country='JAPAN';MonthAvg=amount/12;datalines;1998 US CARS 194324.121998 US TRUCKS 142290.301998 CANADA CARS 10483.441998 CANADA TRUCKS 93543.641998 MEXICO CARS 22500.571998 MEXICO TRUCKS 10098.881998 JAPAN CARS 15066.431998 JAPAN TRUCKS 40700.34;Correct answer:dTo read instream data, you specify a DATALINES statement and data lines, followed by a null statement (single semicolon) to indicate the end of the input data. Program a contains no DATALINES statement, and the INPUT statement doesn't specify the fields to read. Program b contains no data lines, and the INPUT statement in program c doesn't specify the necessary dollar signs for the character variables Country and Vehicle.10.Which SAS statement subsets the raw data shown below so that only the observationsin which Sex (in the second field) has a value of F are processed?a.if sex=f;b.if sex=F;c.if sex='F';d. a or bCorrect answer:cTo subset data, you can use a subsetting IF statement in any DATA step to process only those observations that meet a specified condition. Because Sex is a character variable, the value F must be enclosed in quotation marks and must be in the same case as in the data set.Chapter 6: Understanding DATA Step Processing Answer Key1.Which of the following is not created during the compilation phase?。

会议管理制度英文翻译
会议管理制度英文翻译1. IntroductionThe purpose of this Conference Management System is to provide a comprehensive and organized framework for planning, organizing, and executing conferences within our organization. This system aims to streamline the conference management process, improve efficiency, and ensure that all conference activities are carried out in a systematic and professional manner.2. ScopeThis system applies to all conferences organized and hosted by our organization. It covers the entire conference management process, including planning, budgeting, venue selection, participant registration, program development, logistics coordination, and post-conference evaluation.3. Key Components3.1 PlanningThe first step in conference management is the planning phase. This involves defining the conference objectives, identifying the target audience, establishing a budget, and creating a timeline for the conference. Key tasks during the planning phase include selecting a conference theme, determining the conference format (e.g., in-person, virtual, or hybrid), and establishing a planning committee.3.2 BudgetingEffective budgeting is critical for the success of any conference. The budgeting component of the Conference Management System involves creating a detailed budget that outlines all expected expenses and potential revenue sources. This includes costs for venue rental, catering, technical equipment, marketing and promotion, speaker fees, and participant registration fees.3.3 Venue SelectionSelecting an appropriate venue is crucial for the success of a conference. The venue should be suitable for the size and format of the conference, provide the necessary facilities and amenities, and be conveniently located for participants.

NAND Flash存储管理的jkffs嵌入式文件系统说明书
International Conference on Communication and Electronic Information Engineering (CEIE 2016)To establish file system in industrial storage managementHui-Zhong LiuInstitute of Applied Mathematics Hebei Academy of sciences, Shijiazhuang, 050081,ChinaE-mail:****************Aiming at the Nand flash which is widely used in industrial storage management, theembedded file system named “jkffs”is established. In “jkffs”, a direct addressingalgorithm is described; tnode-tree, variable-tnodelength are used to address most kinds ofnand flash; the method of chunk group is mentioned also. The dynamic wear-levelingalgorithm and static wear-leveling algorithm according to the different erasing times ofblock are presented in “jkffs” to realize the garbage-collection and wear-leveling.Keywords: Jkffs; Ttnode-tree; Variable-tnodelength; Tthreshold.1. IntroductionNAND Flash memory is widely used in the industrial storage management in which embedded system is the core. The log-structured file system designed according to the physical structure characteristics of NAND Flash can solve the embedded system of mass storage management issues.NAND Flash array can be divided into a series of blocks. Each block contains a number of pages, and the block is the smallest erasable unit. Erasing a block means defining all the bits as "1" (defining all bytes as “FFh”). Writing operation, through the programming, turns erased bits from "1" to "0". The unit of reading and writing is the page, the page contains data area and leisure area (OOB, out-of-band), and OOB area is used for software designer. Writing Page and erasing block are the basic operations of NAND Flash. Programming all bytes of blocks for OXFF can release space [1].2. Establishment of The File System2.1. The basic ideas of the file systemThe file system we establish is named “jkffs”. Additional information is stored in OOB area, which is designed to realize the management of NAND FLASH.All the components in the file system, including file, directory, links, devices etc., are entirely regarded as a file .Each file has a special head page store file to preserve the head of mode, length, file name, father object labeling and other information. The basic unit for writing in NAND Flash is the Page (Page) called chunk in the file system, which has different meanings. Page refers to the actual data storage areas on the NAND Flash Memory, while the chunk is the logical data storage areas allocated by the file system. Their sizes can be different.With 2048+64byte as a page of NAND Flash chips, for example, the file system use 8 Byte on OOB district to store the relative file system information [2], and design a erasing-times mark (Erase_num, 8 bits), to recover block and realize the wear-leveling. The directory structure of the file system must be built in the memory during the process of loading the system. Reading OOB contents is only needed to scan each Chunk and from the system marks in the OOB, it can be determined whether the Chunk is head or data. Then according to the contents of the file head chunk and the information such as object ID, chunk ID of data chunk, establish a corresponding object in the memory for each file. After all the Block has been scanned, it would establish the relationships of all objects, and form a kind of architecture in RAM. Thus, the file system would be loaded successfully [3].2.2. Addressing of the file systemEfficient addressing can be realized by creating a node tree. Structure definition: union jkffs_Tnode_union {union jkffs_Tnode_union *internal[8];}This is a pointer array of length 8. The node tree at the bottom, created according to this structure, becomes the leaf nodes and the middle is internal node. They have the same structure. When the nodes is the internal nodes, each element of the array will point to the next layer of child node; When the node is the leaf node, the array will be splitted into 16 long integer with N bits (Tnodelength), which is the storage location of the file contents in the flash (that is, chunkid).The Tnodelength of leaf nodes determines the maximum addressed space for the file system. For example, Tnodelength = 16, means it can represent 216 =65536 chunk.. As for a NAND flash with 2K chunk , the largest flash address space c is 128 M.It is very convenient to find the files through the node tree. Each tnode used by the internal node has 8 pointers, so three binary codes are needed to index it,therefore when the tree grows a layer high, three codes would be added into the ChunkID. In turn, each three nonzero ChunkID represents a layer of the internal nodes. Meanwhile, each Tnode used by leaf nodes has 16 pointers, so four binary codes are needed to index it.When tnode structure just started to be built, only the lowest level tnode would be established. And when the number of the Chunk was more than 16, an internal tnode would be established in the tree, and NO. 0 pointer would point to the Lowest Level Tnode. While more and more Chunk is read, new tnode will be added and the node tree is also more and more higher.2.3. Variable-Tnodelength in the node treeTnodelength of bottom node in the node tree determines the maximum space which can be addressed by file system . If The size of the chunk is 512 byte, 32 MB NAND Flash need 65536 chunks, and it needs 16 bit to index chunk. Similarly, 64MB nand flash needs at least 17 bit to index all the chunk and 128 MB NAND Flash needs18 bit. In order to facilitate processing, the tnodeSize must be the multiple of 32bit, tnodeSize = (tnodelength * 16) / 8, the unit is Byte. Tnodelength represents the length, because the Tnode of level 0 is 16 physical chunk index. From the foregoing, tnodelength is the size of physical chunk index, and the unit is bit. In order to make tnodeSize the multiple of 4 Byte, 64 M flash’s chunk index bits has to be 18 bit at least. Thus tnodelength = 18 can directly addressed 128 MThe way by increasing tnode-length can realize the management of the most large capacity of NAND Flash on the market at present, say, tnodelength = 20, the file system has the maximum space: 220 * 2 K = 2G for addressing. But such established node tree occupy too much RAM space in embedded system, which affects system performance, and it is not quite flexible for the protean design of embedded system.In system initialization process the information of NAND Flash is first read, the total number of pages can be obtained by multiplying blocks of Flash ( nblocks) by pages of each block, which means that file system need to manage these pages, and then figure out tnodelength of bottom node .specific algorithm is as follows:1) C alculated the total number of pages x = nChunksPerBlock * nBlocks2) w hen X > 1, shift X 1 to right ,bits= bits+13) r epeat , until x <= 14) i f X is odd number,X=X+15) endFlow chart as shown in Fig. 1Bits is bit length, and assign to tnodelength. This way can solve the problem that fixed tnodelength occupies too much RAM in the system, and can manageFig. 1 Tnode-length algorithm flow chartIn the actual system design, if bits is too large, Chunk array can be considered. Make one Chunk to match more pages, through which can reduce the tnodelength.Thus,the goal of managing NAND Flash memory can also be achieved. That is, through synthesizing certain chunk into a group with a same Id, may also increase the addressing chunk scope. At this time, the Pages of chunk are different. Supposing that a Chunk corresponds two pages andtwo continuous pages can becalled d_Chunk, including 4096bytes data, here d_Chunk [0], d_Chunk [1] correspond relevant page separately, as shown in Fig. 2:Fig. 2 Chunk array and Page relationship schemes3. Garbage- Collection and Wear-LevelingThe life of the flash memory is limited, it is determined by the maximum erasing time of the block .Therefore, wear-leveling algorithm should be design to distribute the erasing and writing operation evenly on each block and its impact on performance should be as low as possible. The process of erasing blocks and reuse it is called “garbage-collection”. Considering the using frequency of data with garbage-collection and wear-leveling, we designed two algorithms: dynamic and static wear-leveling algorithm.3.1. Dynamic wear-leveling algorithmThe working range of Dynamic wear-leveling algorithm is the updated frequently data space and unused space, it will be realized in the writing of data.Fig. 3 Garbage-collection Flow chartThe algorithm supplies a good way to manage the dynamic data in flash memory. It can guarantee a fixed number of free blocks, as well as can solve data writing delay and accumulation. Two values were used in the blockrecovery algorithm above, they are Min and TH1. Min is the number of recovered dirty block each time when the idle block list is empty. Next, TH1will be explained.In this algorithm, garbage-collection will happen when free block list is empty, while the recovery of dirty block may need to copy the effective data of dirty block first, so the erasing should be done by descending order of useless data page when recovering block, here TH1 means the lower limit of dirty block though “Aggressive Mode”, the recovery can be operated from the beginning of the list of dirty block when the value is more than that.The Min must meet the conditions for Min ≥ TH1.If Min is too large, the number of free blocks will increase, accordingly, the available memory space will reduce; If Min is too small, it cannot solve the problem of data accumulation completely. In the file system, Min is 1/10 of the total block, namely Min = nBlocks / 10, TH1 = Min / 2.3.2. The realization of static wear-levelingIn the practical application of the embedded system data storage have such characteristics: most files are small files, but large files take up most of the storage space; the blocks of small files are updated much frequently. Thus the following situation will appear: the erasing blocks of small files have more erasing times than that of big files, which leads erasing times of small files’erasing blocks will reach the upper limit of erasing times faster and the life of the whole flash memory will be used up.In order to deal with this kind of static read-only data, we designed static wear-leveling algorithm. When the garbage-collection was triggered, read the EraseNum from OOB of the erase block in the clean blocks list, which marked the erasing times, then find out biggest and smallest erasing times. Then do subtraction between them, if the value is bigger than threshold, it can be concluded that erase with minimum number of erasing stored static data, and it needed to be moved. And because the static data are usually bigger and take up more erase blocks, the number of blocks with the minimum time of erasing is more than 1. Therefore, in order to better achieve erase equilibrium, it is necessary to scan the clean block list again after moving operation, and find out the block with maximum erasing times. Specific algorithm is divided into the following steps:1)S can clean block list, and find out the blocks with the biggest and smallest erasing times, then record the number EraseMax and EraseMin respectively, and name the blocks A and B respectively.2) I f “EraseMax - EraseMin≥TH2”, erase block B store the static data, it must be done with moving operation.3) s elect one block from the free block list, copy the data of A to it; Then erase A, and then copy the data of B to A; And then put B to the dirty block list for the storage of data updated frequently.4) R epeat above three steps, until “EraseMax - EraseMin≥TH2” is false, That is, all the static data have been moved.The value of TH2 is very important in the algorithm. If the threshold is too large, the number of static file storage blocks needed to be released will be greater than that of free blocks, and effective data cannot be all received. Conversely, if threshold is too small, blocks for static data file storage cannot be released promptly, and frequent data moving will affect the performance of the system. Usually it is better to set the value of TH2 between 200 to 500. In this file system TH2 = 250.4. ConclusionAt present the most reasonable management of NAND flash memory of the file system mostly uses the log-structured design ideas, such as JFFS, yaffs, etc. The file system “jkffs ” is developed and completed .Practice has proved that “jkffs ” could flexibly manage many NAND Flash with various size at present.

Today we are going to learn about the "Document Management Process" in our company. It's super important because it helps us keep all our files organized and easy to find. Let's dive in!First, when we receive a new document, we need to make sure to save it in the right folder on the computer. This will helpus keep track of everything and make sure we can access it whenever we need to.Next, we need to give the document a clear and descriptive name. This way, we can easily search for it later on if we need to find it quickly. It's like giving each document its own special nickname!After that, we need to make sure to update any changes in the document. If there are any new versions or edits, we should save them with a new name or in a separate folder. This will help us keep track of the most recent information.Lastly, we should regularly review and clean out our files. If there are any documents we no longer need, we should delete them or move them to an archive folder. This will help us keep our computer nice and tidy.Remember, keeping our files organized is super important for the success of our company. So let's make sure to follow these document management processes carefully. Happy filing, everyone!篇8Hey guys! Today we are going to talk about the "Document Management Process". It's super important to know how to manage documents properly in the workplace. So let's get started!First things first, what is a document? A document is any piece of paper, file, or electronic record that has important information on it. It could be a report, a memo, an email, or even a sticky note. It's really important to keep all these documents organized and easy to find when you need them.Now, let's talk about the document management process. This process includes creating, storing, organizing, and retrieving documents. When you create a document, make sure to name it something that makes sense and saves it in the right folder on your computer or in a file cabinet. This will make it easier to find later on.When storing documents, make sure to use safe and secure methods. You can store electronic documents on a server or cloud storage, and physical documents in a locked cabinet. This will protect sensitive information and keep everything organized.Organizing documents is super important too. You can use folders, labels, or tags to group similar documents together. This will make it easier to find what you need quickly and efficiently.And finally, when you need to retrieve a document, make sure you know where to look for it. Keep track of where you save your documents and remember to update them regularly.So there you have it, the document management process in a nutshell. Remember to keep your documents organized, secure, and easy to find. This will make your work life a whole lot easier!篇9Hello everyone, today I'm gonna talk about the super-duper important subject of "Document Management Process". So, let's get started and learn all about it!First of all, what is document management? Well, it's all about how we organize and store our files and papers in a neat and tidy way. It's like having a perfect system to keep all our stuff in order. And why is it so important? Because when we need to find something, we can do it super quick and not waste time searching around.Now, let's talk about the steps in document management. Step one is to decide what kind of documents we have. Are they important papers, drawings, or maybe photos? Once we know that, we can move on to step two which is sorting them out and putting them in different folders or boxes. Step three is labelingeverything so we know what's inside. It's like giving each document a name so we can find it easily later.Next, we have step four which is storing the documents in a safe place. We need to make sure they won't get lost or damaged. Maybe we can put them in a filing cabinet or a special storage room. And finally, step five is about sharing the documents with others if needed. We should always ask permission before giving out any confidential information.So, that's the basic idea of document management. It's all about being organized and keeping our files safe and easy to find. Remember, the better we manage our documents, the smoother our work will be. So, let's all work together and make our document management process super awesome! Thanks for listening, bye-bye!篇10Hey guys! Today we are going to learn about the "File Management Process" at work. It's super important to keep our files organized and up-to-date, so let's dive in!First off, let's talk about creating new files. When we have a new project or document to work on, we need to make sure tosave it in the right folder on our computer. This helps us easily find it later on and keeps everything neat and tidy.Next, let's chat about naming our files. It's best to use clear and descriptive names that tell us what the file is about. For example, instead of naming a file "Untitled Document," we could name it "Sales Report October 2021." This makes it much easier to know what each file is without having to open it.Now, let's discuss organizing our files into folders. Folders are like virtual filing cabinets for our documents. We can create different folders for different projects or departments to keep things sorted. It's like having separate drawers for our toys or books at home - everything has its place!Lastly, let's touch on backing up our files. It's crucial to regularly back up our important files to avoid losing them in case of computer crashes or accidents. We can save copies to an external hard drive or use cloud storage services to keep our files safe and sound.Remember, good file management skills make our work easier and more efficient. So let's keep our files organized, named correctly, and backed up regularly. Keep up the good work, team!。

动画制作文件命名规范
动画制作文件命名规范英文回答:Animation file naming conventions are essential for organizing and managing animation projects effectively. A well-structured naming system ensures that files can be easily located, identified, and shared among team members. There are several key elements to consider when creating a naming convention for animation files.First and foremost, it is crucial to establish a consistent and logical structure for naming files. This structure should provide relevant information about the content of the animation and its version. For example, a common practice is to include the project name, followed by a brief description of the shot or scene, and finally, the version number. This helps to prevent confusion and allows for easy identification of different iterations of the same animation.Additionally, including a date or timestamp in the file name can be beneficial, especially when working on projects that involve frequent updates and revisions. This ensures that the most recent version of the animation can be easily identified and accessed.Furthermore, it is important to use clear and concise language in file names. Avoid using abbreviations or acronyms that may not be universally understood by all team members. Instead, opt for descriptive words that accurately represent the content of the animation. This helps to avoid any misunderstandings and facilitates efficient collaboration.Another consideration is the use of file extensions. It is recommended to use standard file formats, such as .mov or .mp4 for video files and .png or .jpeg for image files. This ensures compatibility across different software and platforms.In addition to the above guidelines, it can be helpful to include a unique identifier for each file, such as aproject or client code. This can be particularly useful when working on multiple projects simultaneously or when collaborating with different clients.To summarize, a well-designed animation file naming convention should have a consistent and logical structure that includes relevant information about the animation's content and version. It should use clear and descriptive language, avoid abbreviations, and include a date or timestamp when necessary. Standard file formats and unique identifiers can also be incorporated to enhance organization and collaboration.中文回答:动画制作文件的命名规范对于有效组织和管理动画项目至关重要。

FUJITSU Software BS2000 LMS V3.5 库管理系统说明书
DatasheetFUJITSU Software BS2000 LMS V3.5Library Maintenance SystemLMS is the central library management system in BS2000.LMS is used to create and manage program libraries, as well as to manage and edit the elements contained in those libraries.Program libraries are PAM files which are processed using the PLAM library access method (PLAM: Program Library Access Method). For that reason they are also referred to as PLAM libraries. The PLAM access method is included in the BS2000 basic configuration.LMS makes an excellent software development support tool, providing the following standout functions:standardized program library system, element version management, the SDF statement language, protection mechanisms which can also be used for elements, and options for automating program development and library management.LMS is a sophisticated and mature BS2000 standard product which supports program development, maintenance and documentation.Program librariesA program library is a file with a substructure. It contains elements (“members”) and a table of contents listing the stored elements. Each library has an entry in the system catalog. The user can specify the name and other file attributes, such as retention period or sharability.Storing multiple elements in a library relieves the load on the system catalog, since only the library is entered there, and not each element. What’s more, it also saves storage space, since the elements are stored in the library in compressed form.ElementsAn element is a logically related set of data, e.g. input/output data, a procedure, a link module or a source program. Each element in the library can be addressed individually.An element in a program library is uniquely identified by its type, its name and a version identifier. Multiple versions relating to one element type and name can also be stored.In addition to standard types for typical contents, users can define their own types using names up to 8 characters long (user types) in order to structure their libraries more efficiently and automate processing of library elements with the aid of procedures in a much more finely grained manner.Version managementExperience teaches us that software elements need to be changed frequently. For this reason they must be easy to change and the different versions must be uniquely identified.Symbolic version identifiers support library management automation. Examples available include: *HIGHEST, for the highest version identifier, and *INCREMENT, to increment an existing version identifier in accordance with a selectable rule.LMS provides compact storage of differential sets (deltas): elements which have been created from a prior element due to changes generally differ only slightly from their predecessor. With LMS, only the differences compared with the predecessor then need to be physically stored. When such element versions are read, these deltas are merged in again at the relevant points, thus making the complete element available to the user once more.Integration into the programming environmentThe utility routines of the programming environment, such as EDT, compilers etc., can directly access program libraries.Link-and-load modules can be stored directly in program libraries by all the compilers and by the BINDER link editor. However, LMS can also copy link-and-load modules that originate from the old linker-loader system with the TSOSLNK linkage editor into the program library.The LMS subroutine interface provides users with convenient options for processing LMS libraries and their contents, from directly within a user program (Assembler, C, COBOL). In this case LMS is loaded dynamically.Multiple access to program librariesA library can be opened by one or more users for both read-only and write access.An element can be read concurrently by a number of users, but can only be accessed for writing by one user at a time. While an element is open for writing, no other access – including read-only – is possible to this element. Other elements of the library can be accessed. Statement formatLMS supports the SDF statement format familiar from the BS2000 command language. Statements in ISP format continue to be supported for compatibility reasons. New functions are only provided in SDF format, however.Basic functionsLMS provides the following basic functions:⏹Creating and managing libraries⏹Adding elements to a library, copying elements into anotherlibrary, and outputting elements from a library into a file⏹Managing, listing and editing elements⏹Comparing elements⏹Making LMS functions available from within EDT⏹Maintaining a Last Access Date for elements⏹Defining default settings in a start file.Protection functionsLMS supports the use of passwords and basic access control lists (BACLs) to provide a comprehensive, multi-tiered protection concept for libraries and elements.When the SECOS product is deployed, the GUARDS subsystem can be used to set up an extended, user-definable access control mechanism for libraries and elements.Protection rights are transferred to the elements on request when files are added, and vice versa when elements are output into files.All security-related actions relating to libraries and elements can be logged by linking PLAM to the SAT subsystem (part of the SECOS product).When elements are deleted, data that is no longer required can be selectively overwritten with the value X'00' (security erase). Borrowing procedureThe borrowing mechanism provides a means of controlling access to elements that are being modified e.g. by several developers working on a project.An element can only be written if the writer has previously been entered as the current holder for the source version.During writing, a history comprising the return timestamp, the holder’s user ID and optionally a user-specific comment is added to the new element status.The processing status of an element is output as an attribute in the table of contents and can also be used as a selection criterion. Make functionalityThe make functionality familiar from and successfully employed in other operating systems is also available under LMS. Using make enables projects to be implemented efficiently, since only absolutely essential steps are performed. The interface is tailored to match the BS2000 system.For a given target object, the make function describes the source objects on which this target depends, and the actions leading to the creation of the target.Starting from the selected target object, all targets are created from new if the source objects of a target have changed since the last time the target was generated.TopicsAs well as the selected target object, all associated source objects represent further sub-targets which are handled similarly.A BS2000 procedure is created and can be launched synchronously or asynchronously.To allow the description to be reused, the sequence of LMS-specific make statements should be stored in a separate element, called a make file.Output of library information to S variablesLMS supports the output of selected data to S variables. This enables easy and efficient creation of command procedures (S procedures), e.g. for automated library administration.If structured variables and lists are to be used here, then the chargeable product SDF-P is a software prerequisite. Reorganizing librariesLMS reorganizes a library so that the maximum amount of disk space not currently used by elements is released.This enables the amount of disk space required for a library to be reduced. In contrast to copying and subsequently deleting the old library, no additional disk space (to the full size of the library!) is required for reorganizing a library.Unlike with the COPY method, however, after REORG-LIBRARY there can still be an amount of free space which, at a maximum, may be as large as the largest element in the library.Technical DetailsRequirementsTechnical Requirements Hardware BS2000 Business ServerTechnical Requirements Software BS2000/OSD-BC V8.0 or higher or OSD/XC V8.5Demands on the user Knowledge of BS2000Installation and operationOperating mode Interactive and batch modeImplementation language Assembler, SPLUser interface Commands in English, message texts in German/EnglishInstallation By the customer according to the release noticeDocumentation and trainingDocumentation LMS User GuideLMS Subroutine Interface on the manual server.Training See course offerPurchasingConditions This software product can be leased by the customer in accordance with theconditions for the use of software products.Ordering and delivery This software product may be obtained from your local Fujitsu TechnologySolutions GmbH regional office.Products/fts/products/In addition to BS2000, Fujitsu offers a full portfolio of other computing products: ■ Storage systems: ETERNUS■ Server: PRIMERGY, PRIMEQUEST, Fujitsu SPARC M10, BS2000 Mainframe■ Client Computing Devices: LIFEBOOK, STYLISTIC, ESPRIMO, FUTRO, CELSIUS ■ Peripherals: Fujitsu Displays, Accessories ■ Software ■ Network Solutions/fts/solutions Infrastructure Solutions are customer offerings created by bringing Fujitsu’sproducts, services and technologies togetherwith those from partners.Industry Solutions are tailored to meet the needs of specific verticals.Business and Technology Solutions provide a variety of technologies developed to tackle specific business issues such as security and sustainability, across many verticals.

The file system registers the location of files and directories on the disk. 注册磁盘上文件和目录的位置
It also has subdirectories like /bin and /sbin.
If we install an administrative software like network monitoring, all the files will be stored in /sbin. That means only root user can use it. If we install any media player it will be stored in /bin, that means local user can also use it.
It is the default downloading directory, just like downloads folder in windows
11. /proc
The process ID's of all the running programs are stored in this folder. Just like the task manager in Windows. To see all the process, we can use the command
File System Structure 文件系统结构
The file system structure is the most basic level of organization in an Operating System. 最基本的层次
An Operating system interacts with its users, application and the security model 操作系统与用户、应用程序相互作用 are dependent upon the way it organizes files on storage devices. 安全模块则依靠它在存储设备上组织文件的方式
/dev/hdb---- primary slave 第一通道从硬盘 /dev/hdc----- secondary master 次要主机(第二通道主硬盘) /dev/hdd-----secondary slave 第二通道从硬盘
/dev/hda1----- first partition 第一分区 /dev/hda2-----second partition 第二分区

1. /root
This is the home directory of the root user. (just like the my documents folder in windows)
2. /boot
This folder contain the booting files of the Linux Operating System. So that it is very important, we must create it as a separate partition at the time of installation.
6. /bin
This folder contain all the commands (binary executable files) that a local user can use in the computer.
7. /sbin
This folder contain all the commands (binary executable files ) that a root user can use in the computer
最基本的层次
So it is very important to learn about the file system in Linux. In this topic we will learn about,
how to create file system, mounting the file system and disk quotas. 将学习如何创建文件系统、挂载文件系统以及磁盘配额
/dev/sda1-----SATA HDD first partition /dev/fd0 ---- floppy
If we connect a pendrive (USB drive) and it will show the name as SATA , why? 如果我们连接一个优盘,会显示成SATA, why?
/dev/sda ----- SATA1 /dev/sdb------SATA2 /dev/sdc------SATA3 /dev/sdd-----SATA4
/dev/sda1-----SATA HDD first partition

9. /lib
All the library files are stored in this folder. Library files are used for programming in Linux.
10. /net
