The prospect of reducing the time, cost and risk of system development has increased the interest in developing systems from COTS (Commercial-Off-The-Shelf) products. The development of complex COTS-based systems is known to be an intricate and risk prone process. There are three main reasons for this. Firstly, suppliers develop COTS products with the objective of satisfying the needs of the ma...

The process of knowledge acquisition of COTS (Commercial Off-The-Shelf) components may provide many difficulties. The existence of a huge amount of diffused information is one of the existing inconveniences related to the selection process. Furthermore, the problem of a choice of a proper methodology supporting COTS component selection and evaluation processes is characterized by a high level o...

Though the importance of COTS components selection is well recognized by the Software Engineering community, the process of searching candidate COTS components is associated with major difficulties related with the diversity, size, evolvability and interoperability of the COTS components as well as the lack of structure and subjectivity of the COTS marketplace information, making the searching ...

The spore coat of Bacillus subtilis has a unique morphology and consists of polypeptides of different sizes, whose synthesis and assembly are precisely regulated by a cascade of transcription factors and regulatory proteins. We examined the factors that regulate cotS gene expression and CotS assembly into the coat layer of B. subtilis by Northern blot and Western blot analysis. Transcription of...

Several aspects of Commercial Off-The-Self (COTS) component integration are being discussed in the literature as challenges to utilizing COTS components in software development. Among these issues are interface matching, inter-component communications, functional matching, and integration testing. This paper highlights potential problems and risks associated with integrating COTS components, ev...

One of the most significant changes in the software development area is the trend of building systems incorporating pre-existing software, with special emphasis upon the use of commercial-off-the-shelf (COTS) software components. COTS describes software commercially available as stand-alone products and which offer specific functionality needed by a larger system into which they might be incorp...

Since the Commercial off-the-shelf (COTS) software become widespread components in the market for building the systems with less time and cost, the COTS evaluation and selection becomes a non-trivial task. There are many models attempted to propose a set of characteristics for evaluating and selecting COTS software. However, these models have concentrated on the functional and quality character...

آگاهی از میزان تاج‌پوشش درختان در مناطق شهری به‌علت تأثیرات آن کاهش آلودگی‌‌های هوا، آلودگی صوتی، جلوگیری باد، ذخیرة نزولات آسمانی، و کنترل رواناب‌های بسیار ضروری است. ازآن‌جا‌که استخراج با روش‌های دستی وقت‌گیر پرهزینه است، تکنیک‌های سنجش دور می‌توانند ابزار مناسبی برای تأمین این داده‌ها باشند. طبقه‌بندی شیء‌پایه، انتخاب پارامترهای بهینة قطعه‌بندی، به‌ویژه پارامتر مقیاس، اهمیت بسیاری دارد معمول...

Component Based Software Developers are faced with the challenge of selecting appropriate Commercial Off-The-Shelf (COTS) products, because the marketplace is characterized by a variety of products and product claims, extreme quality and capability differences between products, and many products incompatibilities. Although a multiplicity of COTS selection method have been proposed in literature...
