Modern software systems are becoming increasingly complex, relying on a lot of third-party library support. Library behaviors are hence an integral part of software behaviors. Analyzing them is as important as analyzing the software itself. However, analyzing libraries is highly challenging due to the lack of source code, implementation in different languages, and complex optimizations. We observe...
In order to realize the pressure energy harvesting of pneumatic system, a novel pneumatic-piezoelectric generator is proposed in this paper. The bending deformation of piezoelectric plate is induced under the impact of air supply pressure. The transformation from pressure energy to electric energy is realized based on direct piezoelectric effect. The simulation analysis of flow field distribution...
Software execution environment, interfaced with software through library functions and system calls, constitutes an important aspect of the software's semantics. Software analysis ought to take the execution environment into consideration. However, due to lack of source code and the inherent implementation complexity of these functions, it is quite difficult to co-analyze software and its environment...
This paper was to design a cyclic RGD (Arg-Gly-Asp) peptide tumor inhibitor with high affinity to integrin αvβ3 receptor by molecular docking technique, determinate the characteristics of the cRGD dimer in vitro and prepare 99mTc-cRGD dimer tumor probe. cRGD molecule library was built and an optimal structure of cRGD peptide with the best score that was Cys-Arg-Gly-Asp-(D)Ser-Cys was screened out...
Many MPI libraries have suffered from software bugs, which severely impact the productivity of a large number of users. This paper presents a new method called FlowChecker for detecting communication-related bugs inMPI libraries. The main idea is to extract program intentions of message passing (MPintentions), and to check whether theseMP-intentions are fulfilled correctly by the underlying MPI libraries,...
The graduation project is the final link of higher education. Its quality is the embodiment of the teaching quality of a university, is the comprehensive application embodiment of specialty knowledge ability learned by students, and also is the evaluation of university graduate's quality. The current employment situation of college students is worrying. Integration of graduation design and employment...
While software reliability in large-scale systems becomes increasingly important, debugging in large-scale parallel systems remains a daunting task. This paper proposes an innovative technique to find hard-to-detect software bugs that can cause severe problems such as data corruptions and deadlocks in parallel programs automatically via detecting their abnormal behaviors in data movements. Based on...
