In this paper, we claim that a specialized aspect module is not required. Instead, we propose an expressive aspect-oriented composition mechanism which can be applied upon existing modules. At the design level, the CoCompose modeling framework is introduced which is based on Model Driven Development. CoCompose allows step-wise refinement from a high-level design to the lowest level design or co...

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.

In our previous papers[2, 1, 4, 3], we report our use of event-condition-action formalism for modeling software process, and the Adele trigger mechanism to control this execution. Although, this approach produced very good results, it has various drawbacks, including: (1) the formalism is low level; (2) trigger execution may be di cult to control; and (3) the software process description is dis...

Abstraction is the cornerstone of high-level programming; HTML forms are the principal medium of web interaction. However, most web programming environments do not support abstraction of form components, leading to a lack of compositionality. Using a semantics based on idioms, we show how to support compositional form construction and give a convenient syntax.

This paper describes an integrated system for dextrous manipulation using a Utah-MIT hand that allows one to look at the higher levels of control in a number of grasping and manipulation tasks. The system consists of a number of low-level system primitives for grasping, integrated hand and robotic arm movement, tactile sensors mounted on the fingertips, sensing primitives to utilize joint posit...

The work described in this paper is an investigation of COTS-based software development within a particular NASA environment, with an emphasis on the processes used. Fifteen projects using a COTS-based approach were studied and their actual process was documented. This process is evaluated to identify essential differences in comparison to traditional software development. The main differences,...

Within a worldwide business-strategic project the development of a software system requires a methodology to monitor resources consumption and service levels since high level design. IRIDIUM ® is a digital communication network based on satellites, designed to provide personal mobile services anywhere on earth. Telesoft developed an Operation and Maintenance Center for the Iridium's Gateways an...

Cost estimation is an important aspect of the management of software development projects. Most cost estimation models require an estimate of the size of the program to be developed. Accurate size estimation is thus critically important. This study relates the size of small Pascal programs to information available at successive stages in their development. As might be expected, increasingly acc...
