Li Sha Reflection 1 Draft(Revised)
Li ShaEducation Reflection 1 February 27, 2009A Friend, A TeacherMr. Zhao was the only teacher who gave me a feeling of friendship. He taught me English when I was in junior high. He was twenty-seven years old at that time, however, he had already finished three bachelor’s degrees by self-study, in which English was not his primary major. To a junior high student like me, this would be such a wonder that I could not dare to think of it.He did a good job in teaching us by interacting with all the students. One of his typical sayings was, “We are all learners of English in my class. We have to study together and make progress together; I’m not your teacher but your partner.” It was the first time in my life that I heard such warm words, and the conventional strictness and seriousness of our teachers was swept away by his kindness and friendship. He did what he said; in the following days, he delivered his knowledge about English like an elder brother in the class and studied hard like a little child after school. He told us that there is nobody who is unable to learn anything; those who feel a disability are always the people who are unwilling to make efforts.In my memory, Mr. Zhao was an all-rounder. One day in my second year of junior high, I was doing my mathematics homework in the classroom and was puzzled a lot by a question. There was no one who was good at this subject there. Surprisingly, Mr. Zhao saved me. He looked at my book and thought for a short moment then drew some diagrams and explained them with much clearer and more understandable sentences than our mathematic teacher did. This was the moment that I established the highest respect for him as a teacher of arts and wishing to be a teacher as excellent as him in the future. After this I gradually realized that there seemed to be nothing that could daunt my idol. During our first two years, he had taught us a lot and told us a lot, from arts to science, from study to life.Beauty comes to its end faster. When we were in grade three, he stopped teaching us because of heart disease; it was so pitiful that I can’t even remember how the last year of my middle school passed.I hadn’t heard about Mr. Zhao until I was a freshman in the university when someone else told me that he had just taken the master’s degree of the Peking University. He, had made another wonder.I have not heard about him for a long time now. However, there is one faith of mine, that as long as I try my best I can be a person like him.。
Li Sha Summary Draft(Revised)
Li Sha April 22, 2009Summary and Response“The Last Leaf”is a master piece of O’Henry whose short stories earned great fame by unexpected endings. Johnsy was a poor, young painter who was hit by pneumonia. Sue, Johnsy’s friend, looked after her carefully, however, she still didn’t get better. The disappointed girl counted ivy leaves outside the window everyday predicting that she would die when the last leaf fell. Their neighbor Mr. Behrma was also a painter with no master piece. He painted a leaf on the wall to save Jonhsy. But he also had gotten pneumonia in that raining night and was dead in two days. At last, the last leaf was considered as his master piece.This is a story with a contradictory ending. On one hand, Johnsy recovered because of the painting. On the other hand, her recovery cost Mr. Behrma’s life, though he had made his master piece before his death. Actually, we can infer that Mr. Behrma might not be so excellent in his field. That’s why he failed to win success during his life time. Then why could the last leaf saved Johnsy? S he didn’t want to die, and hoped that there would always be leaves on the tree. When she saw the last leaf, she had n’t even made any judgment.The ending seems to suggest that, sincere care between people is much more precious than any achievement. It also proves the power of mind. When Johnsy was counting the ivy leaves, she always murmured, “When the last leaf falls, I will die.”The last leaf d idn’t fall and she didn’t die. The sacrifice of Mr. Behrma overcame his poor skill and gave him his only master piece. This tells us to cherish love between ourselves and trust the power of the mind. When you insist on something constantly, you will you win finally.。

Simulation produces a random instance of the model that conforms to the constraints.The absence of an instance implies that most probably the model is inconsistent.It is possible from within the Analyser,to narrow down the statements,which produce the inconsistent model.This functionality is called UnSat Core.Assertion checking,checks whether an assertion,which is a statement which should follow from the specification,is satisfied by the model.If it is not,a counterexample is presented to the user.A counterexample is an instance of the model,which violates the assertion.This manual contains some information for both Alloy and the Alloy Analyzer for people familiar with UML but unfamiliar with Alloy.For more information on the Alloy Analyzer and the Alloy language, the reader is refereed to[4]and[1].If the reader is interested in the transformation rules and the restrictions on the translation,the reader is referenced to Chapters2and3.If the reader wants to learn details on how to use UML2Alloy,(s)he is referenced to Chapter4.Finally Chapter5presents a number of simple examples to demonstrate how UML2Alloy can be used.1.1Minimum RequirementsUML2Alloy requires Sun Java1.52Translating UMLThis section provides a brief informal overview of the transformation rules from UML to Alloy.The rules are implemented in UML2Alloy.This section also mentions any restrictions that might exist. 2.1Classes,Subclasses and TypesTranslates Classes to Signatures.If the class isAbstract it will be translated to an abstract Signa-ture.Translates subclasses to subsignatures.The default subclassing semantics is{incomplete,dis-joint}[7,p.72]Enumerators are translated to abstract Signatures and Enumerator literals are translated to sub-signatures with one element(Singletons).For more information see Section2.2.Custom data types.We translate all Classes with the“DataType”stereotype to Signatures.In principle Custom data types are not treated any different than any other Class.RestrictionsX No primitive data types(as defined in the UML standard)are currently supported by the implemen-tation.(Since UML2Alloy0.3,rudimentary support for integer expressions has been introduced).X Multiple packages are not supported.Translation of the classes of one package at a time takes place.X Multiple inheritance is not allowed(the transformation rules have been defined,but not imple-mented in the tool).X Only subclasses with{incomplete,disjoint}semantics are allowed.Again the rules for the rest of the cases have been defined,but we haven’t implemented them.X Subclasses can not redefine attributes,operations.Thus attribute and operation names can not have the same name as the attribute and operation names of the superclasses.X The NameSpace to which Classes can belong to is not restricted by the UML specification.Thusa Class can belong to the NameSpace of another Class(inner Classes).Our rules only supportClasses which belong to the NameSpace of a Package.2.2EnumerationsEnumerations are translated to abstract Signatures.Enumeration literals are translated to Subsignatures,which extend the abstract Signature of the Enumeration.Since each enumeration literal represents only one value,it is declared as a Signature represented by one atom in Alloy.RestrictionsX Enumerations have to be defined in the UML class diagram as Classes with an“Enumeration”stereotype.Enumeration literals have to be defined as attributes of the Class.Attributes have to be of void type.2.3AssociationsPlease note that in this section the term Association End is used,to reference the ends of an association. Even though this term is used in the UML specification(for example see[7,p.14]or[7,p.40]),the UML metamodel reffers to Association Ends as Properties[7,p.29].All association ends have to have names.Role names have to be unique.(Since UML2Alloy0.3 this is not a requirements).If an Association End does not have a name,it will be assigned the name of theUnidirectional Associations:The navigable Association End appears as afield in the Signature to which the original Class the association belonged to,was translated.Bidirectional Associations:Association Ends appear asfields in both the Signatures that partic-ipate in the relation.An additional fact is added to the model,to denote that the relations are symmetric.Multiplicities:Depending on the multiplicity of the Association Ends,the necessary multiplicity facts will be added to the model.RestrictionsX Association End names have to be unique throughout the model(i.e.all Association Ends have to have unique names,in contrast with the UML specification,which allows two separate Association Ends to have the same name,as long as they belong to different Classes).X Association End annotations are not supported(e.g.subsets,ordered etc.).X Only binary associations are supported in the current version of the implementation.X Custom multiplicities are not currently supported by the implementation.Only the predefined(1,0..1,1..*and0..*)multiplicities are supported.X The UML specification allows for unspecified navigability[7,p.41].Such cases are not supported.X The UML specification allows for binary associations with both ends non navigable.Again such cases are not supported.X This version of UML2Alloy has not implemented our rules for aggregation and composition.Asso-ciations with composition or aggregation have to be refactored using the method defined by Gogolla and Richters[3].X Association Classes are not currently supported.2.4Class AttributesClass attributes are translated to Signaturefields.RestrictionsX Attributes have to be of a specific type(i.e.not void).This restriction does not apply for enumeration literals,see Section2.2.X Only attributes with multiplicity of1are supported.2.5Class MethodsClass methods are translated to Alloy predicates.For more information see Section3.2.RestrictionsX Class method can not return any type,other than Boolean or Void.X Operations in UML may raise exceptions.UML2Alloy does not deal with such cases.3Translating OCLThis section presents the details on the translation of OCL statements(invariants and pre and postcon-ditions)to Alloy.IMPORTANT NOTE:NO shorthand notation is supported for OCL expressions.For ex-ample:Use:collection→forAll(v:Type|boolean-expression-with-v)Do NOT use:collection→forAll(v|boolean-expression-with-v)Do NOT use:collection→forAll(boolean-expression)Use:self.attributeDo NOT use:attributeOCL expressions which reference the Boolean values true or false directly are not supported.For example an expression like:if condition thenexpressionelsefalseendifis not currently supported.Instead an expression which always evaluates to false could be used,in the ‘else’branch of the above statement.3.1InvariantsPlease NOTE:The UML standard specifies that invariants are implicitly qualified over all of the instances of the context[5,A.3.1.5].So for example an invariant:context C1inv test:self.attribute=valueis implicitly transformed to:context C1C1.allInstances→forAll(v1:C1|v1.attribute=value)UML2Alloy currently supports only the second expanded form(i.e.with the explicit quan-tification,using allInstances and forAll),NOT thefirst form.Support for thefirst form will be provided in the future.Class invariants are generally translated to Alloy facts.They can also be translated to Assertions.This is defined during the transformation process.For more information please see the examples in Section4.2.2.Each invariant is translated to a predicate and then a fact statement,which references the predicate is added.Restrictions3Translating OCL6X Only Class invariants defined in the namespace of a Class are supported(i.e.Class invariants).X Invariants have to have a name.3.2OperationsThe effects of Operations is defined using OCL pre and post conditions.NOTE:The current version of the implementation only supports postconditions.Operations are transformed to Alloy Predicates.Operations are defined in the context of a Class.Because in Alloy Predicates belong to the NameSpace of the model,an instance of the Signature on which the specification of the Predicate is applied,is passed as a parameter to the Class.Therefore all references to the self keyword used in OCL are transformed to the parameter passed in the Predicate.For a detailed example please see Section[].RestrictionsX The current implementation supports one OCL expression as specification to the Operation.X Pre and Post conditions have to have a name.X Operations can be of either Boolean or Void type.X Currently Operations can not have any parameters.3.3OperationCallExpsIn OCL a large number of expressions are OperationCall expressions.For example equality,implies,and, or,etc.expressions,are considered to be OperationCall expressions.The following shows how those OperationCall expressions are translated to Alloy.3.3.1ImpliesImplies OperationCalls are directly translated to an Alloy implies formula(ImplicationFormula). 3.3.2AndAn OCL and OperationCall is translated to an Alloy binary formula(BinaryFormula)with a AND Logical operator.3.3.3DotDot OperationCall expressions in OCL,are navigation expressions,which use the navigation dot(.).An OCL Dot OperationCall is translated to an Alloy binary expression BinaryExpr with a JOIN DOT binary expression Operation.3.4IfAn OCL If Expression is transformed to an Alloy implies formula(ImplicationFormula).In Alloy an ImplicationFormula can have an else clause,which is what the OCL else clause is translated to.3Translating OCL73.5Iterator ExpressionsAn OCL Iterator Expression is transformed to an Alloy Quantified Formula.RestrictionsX Currently only the forAll and exists Iterator Expressions are supported.X Can only translate Iterator Expressions of the form:Class.allInstances()→forAll or Class.allInstances()→exists.X Do not currently support nested Iterator Expressions.3.6notEmptyAn OCL notEmpty expression is transformed to an Alloy ElemIntFormula.In particular it is translated to an Alloy Formula which enforces the size of the Expression to be greater than zero.For an example please refer to Chapter5.RestrictionsX The notEmpty operator has to be applied to a simple navigation expressions such as:Per-son.allInstances rightarrow exists(p:Person|p.wife→notEmpty).Currently UML2Alloy doesnot support the application of notEmpty to more complicated expressions,such as Iterator Ex-pressions.3.7NotOCL not expressions(expressions with a negation)are directly transformed to Alloy Negation Formulas NegFormula.3.8Variable ExpressionsOCL Variable Expressions(for example in the expression‘’,self is a Variable Expression), are transformed to Alloy Variable Expressions(VariableExpr).3.9Integer ExpressionsUML Class attributes of type integer are transformed tofields of type Int.OCL integer OperationCall expressions that match the pattern expression IntCompOp LiteralIn-teger,where expression is an expression,IntCompOp is an integer comparison operation(i.e.=,<,>,>=,<=)and a LiteralInteger is an expression that denotes to an integer value(i.e.-3,0,1,etc.),are transformed to Alloy ElemIntFormula s.OCL LiteralInteger s[6,p.60]are transformed to Alloy LiteralIntExpr s.RestrictionsX Currently(version0.3)do not support operations(i.e.addition,subtraction,multiplication,divi-sion)over integer values.X Currently(version0.3)only support OCL expressions that follow the pattern:expression Int-CompOp LiteralInteger,where expression is an expression,IntCompOp is an integer comparisonoperation(i.e.=,<,>,>=,<=)and a LiteralInteger is an expression that denotes to an integervalue(i.e.-3,0,1,etc.).4UML2Alloy:Usage ManualThis chapter is a brief guide on how to use UML2Alloy.It is suggested that ArgoUML version0.19.5 is used to develop any models.The reason for this is that ArgoUML provides syntax checking for OCL statements.Please note that apparently some versions(greater than0.19.5)have a bug in the OCL syntax checker.4.1InstallationUnpack the compressedfile of the distribution to a directory.Depending on the platform edit the run windows.bat or run linux.shfiles and make the necessary changes to the path variables.The program can be started by executing the run windows or run linuxfiles respectively.4.2Using UML2Alloy4.2.1Step1Figure4.1depicts thefirst screen that prompts the user to select the path to the XMIfile of the UML model.For a table of the XMIfiles currently supported by UML2Alloy,please refer to Appendix A.The user then needs to select the path to the Alloyfile(textfile with an als extension)that will be generated if the transformation is successful.The user then needs to click on Parse.This starts the parsing method.Messages on the progress appear on the console.The next screen that will be presented to the user is depicted in Figure4.2.4.2.2Step2In this screen the user is presented with all the Invariants and Operations of the UML models.The first column depicts the Operation or Invariant name.The second column shows if the statement is an Invariant or Operation in the original UML model.Finally the third column has a drop down menu, which allows the user to select to what kind of Alloy statement the original UML statement will be transformed.The drop down menu with the selections is populated with the following rules.An OCL Invariant can be translated to an Invariant(Fact in Alloy terms),Assertion or Simulation statement.An OperationFigure4.1:First Screen of UML2Alloy4UML2Alloy:Usage Manual9Figure4.2:Second Screen of UML2AlloyFigure4.3:Final Screen of UML2Alloycan be translated to a Predicate,Simulation or Invariant.An Operation with an OCL statement,which uses the‘self’keyword,can only be transformed to a Predicate.4.2.3Step3The last step towards the translation of UML to Alloy,requires the user to specify the Scope.Figure4.3 depicts a screenshot of this last step.The user can specify the default scope,which is the scope that will be applied to all model elements.This can be overridden for specific model elements if a value other than-1exists in the scope box of a specific model element.By checking the checkbox of the last column the user can enforce that a model element will have instances in the model.For a concrete example on the usage of this function,please refer to the examples in Chapter5.5ExamplesThis chapter presents a number of simple examples to demonstrate the usage of UML2Alloy.5.1Two Unidirectional vs One Bidirectional AssociationsIn this example we want to assert if two unidirectional associations between two classes have the same meaning as one bidirectional association.To do so,we generate the model depicted in Figure5.1.The model was developed using ArgoUML version0.19.5.The model does not have any constraints.We want to assert that the two unidirectional associations between Class1and Class2have the same effect on the model as the bidirectional association between Class3and Class4.The assertion we use is stated in OCL:--We call this statement‘areSame’context Class1inv areSame:Class1.allInstances()->forAll(cl1:Class1|cl1.c2.c1=cl1)This assertion states that for each Class1,if we navigate to Class2and come back we will end up in the same object as where we started.In ArgoUML we define this assertion as an Invariant and when we use UML2Alloy in Step2,we define that we want to translate it as an assertion,i.e.a statement to check.Similarly we formulate the following OCL statement to reason about the association between Class3and Class4.--We call this statement‘bidirectional’context Class3inv bidirectiional:Class3.allInstances->forAll(cl3:Class3|cl3.c4.c3=cl3)We now export the model to XMI format from within ArgoUML.Figure5.2depicts a screenshot that shows how to achieve that in ArgoUML.Next we invoke UML2Alloy.In thefirst step of the transformation process we select the path to the XMIfile and the Alloyfile we want to create.In the next step we select what each OCL statement mapsFigure5.1:Example UML model of two classes connected with two unidirectional and one bidirectional associationFigure5.2:Exporting model to XMI using ArgoUMLFigure5.3:Selecting the mappingto in Alloy.This step is depicted in Figure5.3.The areSame and bidirectional are the two invariants we specified in ArgoUML.By default the statements specified as invariants in the original UML model are translated to invariants in Alloy(facts,according to the Alloy terminology).We want to check if these statements are satisfied.They therefore need to be transformed to assertions,not invariants.We specify that by selecting in the drop down menus that the original OCL invariants are transformed to assertions(indicated by the red arrows in Figure5.3).We then click on the proceed button.Finally in the last step,we specify a default scope of3.We do not need to change any other parameters in the last screen.The transformation process hasfinished without an error and the Alloyfile has been generated in the path we specified in thefirst step.We now need to invoke the Alloy Analyzer to conduct the analysis.On the main Alloy Analyzer window, we Open the Alloyfile generated by UML2Alloy.Wefirst have to Build thefile.Then we need to select from the drop down menu(indicated by the red arrow in Figure5.4)the statement we want to simulate or check.In this case our model has only two assertions,areSame and bidirectional.Wefirst select from the drop down menu the‘areSame’assertion and press on Execute.The Alloy Analyzer produces a counterexample.This is an instance of the model that violates the assertion.This instance is depicted in Figure5.5.From a closer examination of the instance we can see that there is a class,Class10related to Class20,Figure5.4:Selecting the statement we want to checkwhich in turn is related to Class11.The assertion therefore fails,because navigating from a class to another class and back,we end up with different class.Currently the results of the analysis are represented using the Alloy Analyzer representation form(for example as a Tree,as shown in Figure5.5).In the future we plan to represent the results of the analysis in terms of UML(i.e.object diagrams).Checking the bidirectional assertion does not provide any counterexamples.For more information on the Alloy Analyzer,please consult the Alloy website[1].5.2Using UML2Alloy in a model with integer expressionsThis section presents a simple example,where a UML model with integer expressions is transformed to Alloy.5.2.1The UML modelFigure5.6depicts a simple UML model.There two classes.A Person class and an Adult class,which extends the Person class.The Person class has an attribute age of type Integer.An Adult can marry another Adult.There are some OCL constraints(related to integer values)attached to the model.The constraints of the Person class are:context Personinv ageInv:Person.allInstances()->forAll(p:Person|p.age>0)The constraints of the Adult class are:context Adultinv adultInv:Adult.allInstances->forAll(ad:Adult|ad.age>=18)We need to check that in such a model a Person over18can only marry only another Person whose age is over18.This assertion can be formulated in OCL:context Adultinv assertion:Adult.allInstances->forAll(Figure5.5:CounterexampleFigure5.6:UML model of exampleFigure5.7:Screenshot of the second step of the transformation processad:Adult|ad.marry.age>18)We now export this model from our UML modelling environment to XMI format and use UML2Alloy to transform it to Alloy.5.2.2TransformationIn thefirst step of the transformation process we provide the path to the XMIfile that contains the UML model we presented in the previous section.We also specify the path of the Alloyfile that will be created.In the second step of the transformation process we specify how invariants and operations of the UML model map in Alloy.Figure5.7presents a screenshot.This shows that the ageInv and adultInv will be transformed into Invariants(i.e.Fact s in Alloy),while the assertion statement,will be transformed to an assertion in Alloy.The next step in the transformation process is to specify the scopes.As depicted in Figure5.8,when defining the scope we now have another option,the‘Integer Values Range’,which is a drop down menu.Like all elements in Alloy,we need to specify a scope for integer expressions.The user can select from the drop down menu the range of integer expressions for which the model will be probed for a solution or a counterexample.In this case we have selected a range of -32,31.So the largest negative integer in the model is-32,while the largest positive integer is31.The scope of integer values can be chosen according to the biggest positive/negative value we expect in-tegers expressions to have to in the model.For example in our example we care about integer expressions of scope18and over.This is why we chose a scope of-32,31for this example.Figure5.8also shows that we have enforced that there will be instances of Persons and Adults in the model.We have also specified a default scope of4,but defined a specific scope of8Persons.5.2.3ResultsThe Alloy model that was produced by UML2Alloy is depicted in Figure5.9.Executing this Alloy model provides a counterexample.The counterexample is depicted in Figure5.10.Figure5.8:Providing the scopeThe counterexample shows an Adult,Adult0married to an Adult(Adult1),whose age is exactly18years old.This counterexample is produced because according to our OCL invariant an Adult is someone who is18years old or older(someone18years old is considered to be an Adult),while our assertion checks for people over the age of18.More specifically the assertion asserts that all Adults(i.e.People18years or older)will marry another Adult,whose age is over18years old.This obviously produces a counterexample.This small UML example was used as a simple example to show how integer expressions in OCL can be transformed in Alloy.The Alloy counterexample also showed that the Adult,Adult1married Adult0 and Adult0is married to Adult1(Exercise:In this counterexample Adult0is married to Adult1and Adult1is married to Adult0.Is this always the case?Can an Adult1be married to Adult2,while Adult2 is married to a third person,Adult3?).module untitledModelsome sig Person{age:one Int}some sig Adult extends

Li Sha March 10, 2009 Narrative
An Adventure in Childhood
Childhood should be the best cherished period of one’s lifetime. Being impacted by adventure TV plays and cartoons, we were curious about all the unknown spaces around us.
It was a cold winter when the cartoon named the Haier Brothers was showed on TV. The Haier Brothers were confronted with numerous accidents during their adventures. However, they escaped from all the difficulties by their luck and wisdom. That made us firmly believe that man has the capability to conquer nature. And my cousin and I decided to have an adventure of our own. That year, he was seven years old and I was only six.
At the back of my grandma’s house, there was a river; behind the river was a mountain with a lot of caves. Our goal was to reach the highest one; and we would be the first visitors there.
We did it. It was already December, the river seemed completely frozen, and we crossed it smoothly. After we arrived at the other side, we began to climb the mountain. It took quite a long time to get to the target cave, though, we accomplished this second task. However, it was such an ordinary one with nothing interesting in it. Then in order to leave evidence of our discovery, we carved our names on the wall with small stones.
It was time for us, the two heroes, to return home. Heroes in the TV plays always reunite with their families at the end. We went down the mountain along the same route we had climbed. Next, we walked toward the river. It was midday then, the sun was shinning on the river. There came our real difficulty. Ice on the surface would break when we stepped on it because of the warm sunshine. Our feet were wet, and I was very cold. My cousin thought of a good idea, at the time when I intended to cry. He picked up a big rock, and threw it onto the surface; then we walked on the parts where ice didn’t break.
We crossed the river successfully and returned home safely. But we were scolded severely by our grandma. Yet it had been proved by us that humans do have the ability to overcome nature. And the story went like the TV plays, the heroes reunited with their families. Although, it looks stupid now that we have grown up, it is still an important part of my best memories of those happy days.。
