What are the five factors which should be considered for literature circles?
Responding Through Talk: Learning is a social activity, and the cornerstone of social activity is talk. Linguist Michael Halliday (1999) contended that language is used not only to gain access to comm
What are the basic principles of response which move the reader closer to the aesthetic stance?
The over-arching objective of this assignment is to minimize the cost of conducting investigations of False-Positives (FP) and False-Negatives (FN) in the context of credit card fraud detection. An
History of the Propel Toolset: Development of the Propel toolset for model checking C++ applications was started at NASA under funding from the Engineering for Complex Systems (ECS) program in 2001. T
Brief Overview of SAFM: The Shuttle Abort Flight Management system (SAFM) was developed by NASA Johnson Space Center and General Dynamics Decision Systems as part of the Shuttle Cockpit Avionics Upgra
Choosing SAFM: We chose SAFM for several reasons: High criticality—it is capable of determining a safe landing trajectory for the shuttle autonomously in case of a failure requiring an abort
Property Identification: In order to perform model checking, you need to specify a number of properties that the application under analysis must satisfy. JPF detects certain generic properties by defa
Code Instrumentation: Property oracles were inserted into the code using Aspect C++. An important side benefit of using Aspect C++ was that the application could be instrumented without modification o
Model Checking SAFM: Our intention was to use JPF for program model checking of these properties. The SAFM code was partially translated to Java using Propel, a C++-to-Java translator that was being d
MER Arbiter: JPL’s Mars Exploration Rover (MER) software is multithreaded software that must deal with shared resources. The arbiter module prevents potential conflicts between resource re
Explain the term Generalized Symbolic Execution?
Symbolic Execution: The major idea behind symbolic execution (King 1976; Clarke 1976) is to utilize symbolic values, rather than actual data, as input values and to symbolize the values of program var
White-Box Testing: We discuss here a framework that combines symbolic execution and model-checking techniques for automated test case generation in the context of Java programs. The framework is typic
Test-Related Code Annotation and Runtime System: As useful as test systems like JUnit are, test cases do require a significant amount of work to create and maintain, especially since they are implemen
V-V method that overcome Black-Box tesing problem:1. Model checking can produce minimal sets of test cases that guarantee certain coverage criteria for example by using symbolic execution modes of the
Black-Box Testing: Black-box testing assumes an external perspective of the system under test (SUT). It uses concrete input test data to obtain results from the SUT, which are then checked against som
Automated Testing: Software testing is the most generally used technique for verifying and validating software. While testing may not provide the same rigor as model checking, it is far more scalable
VeriSoft (Godefroid, 2005) is a model checker for C and C++; other languages can be used, but components in other languages are treated as black boxes. VeriSoft has been used to find defects in very l
SLAM is a Microsoft project that blurs the line between static analysis and model checking and deductive reasoning. The main goal of SLAM is to check temporal safety properties of C programs (it actua
MCP: Model Checker for C++ (MCP) is an explicit-state software model checker being introduced by the Robust Software Engineering group at NASA Ames Research Center (Thompson and Brat, 2008). MCP was c
LURCH (Menzies et al. 2004) uses random search to explore a state machine’s state space. Because the search is random, it gives no guarantee that the state space has been exhaustively explored,
BOOP Toolkit: The BOOP Toolkit has been developed at the Institute for Software Technology at Graz University of Technology. It is based on the SLAM project and uses the same main concept of verificat
Bogor (Robby, Dwyer, and Hatcliff 2006) is an extensible software model-checking framework which includes: Software model checking algorithms Visualizations A user interface designed to support
What is BLAST in program model checking: The abbreviation is Berkeley Lazy Abstraction Software Verification Tool (BLAST) is a software model checker for C programs. The main goal of BLAST (BLAST webs
