Several process guidelines for the development of COTSbased software systems have been described by informal notations and published in literature. We present here our attempt to model the COTS-based software process using a software process modeling language (E3).We provide models of existing COTS-based development processes, we discuss some of their limitations, and we give suggestions for im...

This paper summarizes the results of a study on fifteen projects that used a COTS-based approach. The process they followed is evaluated to identify essential differences in comparison to traditional software development. The main differences, and the activities for which projects require more guidance, are requirements definition and COTS selection, high level design, integration and testing.

Large corporations are attempting to cut development costs by relying on integrating several COTS to achieve partial or complete business solutions. That the benefits are not turning out as expected is slowly becoming a recognized issue. In this paper, we address some of the reasons why integration of COTS is a challenge.

Understanding the risks of using commercial off-theshelf (COTS) electronic components, specifically laptop computers, in a non-commercial environment is critical to designers of military systems. The environment studied in this paper is that of an unpressurized aircraft cockpit operating at 35,000 feet. During operation in this environment, COTS may be exposed to low atmospheric pressure and ma...

Classes of COTS products can be derived by classification attributes, which define a Cartesian space. Examples of such attributes are the architectural level, the kind of the COTS product (is it a standard, or a service, or an executable component?), and the software life cycle phase in which the product is used (is it a development tool or an executable component?). COTS products belonging to ...

Research on the CHREC Space Processor (CSP) takes a multifaceted hybrid approach to embedded space computing. Working closely with the NASA Goddard SpaceCube team, researchers at the National Science Foundation (NSF) Center for High-Performance Reconfigurable Computing (CHREC) at the University of Florida and Brigham Young University are developing hybrid space computers that feature an innovat...

The dispersal potential of crown-of-thorns starfish (CoTS) larvae is important in understanding both the initiation and spread of population outbreaks, and is fundamentally dependent upon how long larvae can persist while still retaining the capacity to settle. This study quantified variation in larval survivorship and settlement rates for CoTS maintained at three different chlorophyll concentr...

In order to use commercial off-the-shelf (COTS) products, the engineer must be able to prove that the COTS product is equivalent to the specified design. In most cases, this requires observable states, which are usually not available, because the supplier may not know or may not want to disclose the internal states of the system. This paper first presents the following reasons for proving syste...

The dispersal potential of crown-of-thorns starfish (CoTS) larvae is important in understanding both the initiation and spread of population outbreaks, and is fundamentally dependent upon how long larvae can persist while still retaining the capacity to settle. This study quantified variation in larval survivorship and settlement rates for CoTS maintained at three different densities of a singl...
