This paper introduces a framework to produce and to manage quality requirements of embedded aeronautical systems, called the ‘Requirements Engineering Framework’ (REF). It aims at making the management of the requirement lifecycle easier, from the specification of the purchaser’s needs, to their implementation in the final products, and also their verification, while controlling costs. REF is b...

of the ways to fight breast cancer and reduce deaths hazard due to early detection is one of early detection programs in women's breast self- examination. examining breast by oneself increase individuals knowledge of her breast health that helps in detecting breast cancer early. different cultural, social, family and individual factors play roles in women's behavior about breast self- examinati...

aim and background: this study reviewed the effectiveness of self-control training on quality of life in patients with multiple sclerosis (ms). to do so, 40 patients with ms were selected through convenient sampling method among the study subjects with multiple sclerosis recorded in ardabil in 2012 (estimation: n = 350). methods and materials: this was a clinical trial designed as pretest postt...

The purpose of this study was to investigate the impact of negotiated syllabus ondeveloping EFL learners’ writing ability and self-esteem. To do so, first Nelsonproficiency test was administered to 90 participants to select intermediate homogenouslearners. The scores were analyzed and the mean was obtained. Then one standarddeviation above and below the mean was considered as a technique to hom...

Recent efforts to increase online privacy by offering the user a more general choice to opt out of online tracking were mainly pushed by the FTC in late 2010. As the FTC explicitly omitted technical details, browser developers started to implement what they thought might be appropriate to either limit user tracking directly, or let the advertiser know about the user’s wish to not be tracked. Th...

Biological materials. recently. are the building blocks of several self-assembling peptide and protein systems.The main challenge In molecular self-assembly is to design molecular building blocks that can undergospontaneous organization. These cyche peptides were produced by an alternating fl'ell number of D- and Laminoacids.which interact through non-covalent interactions co an array of selfas...

2. Do I hold in my hand the truly appropriate remedy for that lack ? 3. Is the preparation stable, active, pure, and uniform ? 4. Can I accurately determine the dosage ? 5. Is the preparation smoothly active when administered by the route I propose ? 6. Are ill-effects impossible ? Even if these questions cannot be answered in the affirmative, he gives the prescriber one more chance, provided t...

In order to explain how DIYbio knowledge and expertise is developed and shared the use of Practice Theory will help us gain a useful understanding of how working practices are sustained, reproduced and potentially changed. In addition, the development and sharing of thick, evocative, rich descriptions of these practices might contribute to the motivational knowledge of DIYbio practitioners.

DO-178B was based on the consensus of the avionic software community as it existed in 1992. Twenty two years after publication, we have no publically available experimental data as to its efficacy. It appears to work extremely well, since there have been no hull loss accidents in passenger service ascribed to software failure. This is a comforting and surprising result. However, if we don’t kno...

One key step in the development of safety-critical applications is the assessment of the quality of the verification strategy. In practice, structural coverage is the methodology used to ascertain the testing campaign well satisfy a given quality criteria. In this paper, we describe the possible strategies to measure structural coverage in a DO-178B context. After evaluating state-ofthe-art app...
