Coverage analysis measures how much of the target code is run during a test and is a useful mechanism for evaluating the effectiveness of a system test or benchmark. In order to improve the quality of the Linux® kernel, we are utilizing GCOV, a test coverage program which is part of GNU CC, to show how much of the kernel code is being exercised by test suites such as the Linux Test Project. Thi...

During testing, it is nearly impossible to run all statments or branches of a program. It is especially difficult to test the code used to respond to exceptional conditions. This untested code, often the error recovery code, will tend to be an error prone part of a system. We show that test coverage can be increased through an “assertion violation” technique for injecting software faults during...

wireless sensor networks(wsn) have unique properties that distinguished them from other wireless networks and have special challenges. not-chargeable, not-changeable and limited power supplies of sensor nodes is the most important challenge of this networks, and if the power supply of node expired, a part of data maybe lost. because of the importance of covers in wireless sensors, in this work ...

statement of problem: various surgical procedures have been used to achieve root coverage and subepithelial connective tissue graft (sctg) is identified as one of the most successful techniques. recently, acellular dermal matrix allograft (adma) has been developed as a substitute for sctg to avoid removing the palatal connective tissue. purpose: the present study compared the clinical efficienc...

background: due to the marked increase in the burden of cancer both in the developed and developing countries, world health organization recommends planning and implementation of comprehensive cancer control program in all countries. we evaluated evolutionary progress of the population based cancer registries (pbcr), an essential component of the cancer control program. methods: we studied freq...

purpose: to determine the prevalence of uncorrected refractive errors and its determinants in tehran in 2002. methods: a total of 6497 citizens representing a cross-section of the population of tehran were sampled using a stratified random cluster sampling strategy. of these, 4565 (70.3%) subjects participated in the study and were transferred to a clinic for an extensive eye examination and in...

background: localized gingival recession can be treated successfully via coronally positioned fl ap (cpf) and additional use of root surface demineralization agents. the purpose of this study was to evaluate the effects of additional use of ethylene diamine tetraacetic acid (edta) and citric acid as a root conditioner in association with cpf to cover localized buccal gingival recessions. materi...
