Structural model abstraction is a powerful technique for reducing the complexity of a state based enumeration analysis. We present in this paper accurate reductions for high-level Petri nets based on new ordinary Petri nets reductions. These reductions involve only structural and algebraical conditions. They preserve the liveness of the net and any LTL formula that does not observe the reduced ...

This report describes the 2017 Competition on Software Verification (SV-COMP), the 6th edition of the annual thorough comparative evaluation of fully-automatic software verifiers. The goal is to reflect the current state of the art in software verification in terms of effectiveness and efficiency. The major achievement of the 6th edition of SV-COMP is that the verification results were validate...

VALIDATION AND VERIFICATION OF AIRCRAFT CONTROL SOFTWARE FOR CONTROL IMPROVEMENT

The intelligent comparison tool (ICT) was developed to perform intelligent comparisons of text files. The purpose of the tool is to reduce the differences found when comparing two text files to only the meaningful or important ones. This tool contrasts with conventional differencing tools that find all literal differences. This tool was developed to help in the validation of software revisions ...

Here is a list of tools that have been interfaced with AADL in one form or another. This list is not complete. We first give a quick summary of the SAVI Phase 1 POC baseline and then list out tools that had not been included in that demonstration. For a collection of over 250 papers by more than 40 research groups, news, pointers to tools, etc. on AADL see the public AADL Wiki at The baseline i...

Many mobile applications have evolved from simple HTML pages to complex service-oriented applications that have high maintenance cost. This high maintenance cost is due to the heterogeneity of mobile applications, to the fast mobile evolution and to the fast-moving market which imposes short development cycles and frequent modifications. In order to control the maintenance cost, quantitative me...

The experimental result of hypothesis test for hip roof model with = 3:0 is shown in gure 3,where the x axis represents the statistic used in the test and the y axis represents 10, where is the signicance level. Figure 3 shows the result of test mean and covari-ance simultaneously. sample density sample distribution null distribution function null density function Figure 3: Test mean and covari...

Computer vision software is complex involving many tens of thousands of lines of code. Coding mistakes are not uncommon. When the vision algorithms are run on controlled data which meet all the algorithm assumptions, the results are often statistically predictable. This renders it possible to statistically validate the computer vision software and its associated theoretical derivations. In this...

To date, the SCR (Software Cost Reduction) method has been used to specify system requirements. This paper extends the SCR method to hard-ware/software co-design and co-validation. Our approach consists of three steps. First, the SCR method is used to specify the required system behavior, i.e., the required relation between environmental quantities (called monitored quantities) that the system ...
