There is no doubt that the object-oriented paradigm (encapsulation, inheritance, polymorphism and dynamic binding) encourages the building of extensible systems and software reuse. Nevertheless, the desired reusability of software components often cannot be achieved even by using state-of-the-art class libraries/application frameworks or object-oriented programming in general. Based on a large-...

while the application of optical and photonic technologies in the communications, computing, medicine and industrial manufacturing has been growing rapidly, the miniaturization of these technologies has been slow due to the limitation on the diffraction. however, the developments of nanoscale components and guiding methods are continuing with a rapid pace. since waveguiding is a fundamental iss...

Changes of both designs and construction process usually cause spatial changes in facility design and challenges related to spatial change management between various building systems (e.g., Mechanical, Electrical, and Plumbing) and building components. In practice, design changes can be triggered by the needs of the owner, engineers and experts, resulting in spatial changes of as-designed objec...

In this thesis a component-based framework for the evaluation of HVAC performance in buildings is developed. Following the method of the demand development HVAC systems are evaluated by means of their energy effort during planing and maintenance. The evaluation is achieved through: determining the energy requirement and energy requirement's impacting factors using a building simulation determin...

The ability to accurately predict the lifetime of building components is crucial to optimizing building design, material selection and scheduling of required maintenance. This paper discusses a number of possible data mining methods that can be applied to do the lifetime prediction of metallic components and how different sources of service life information could be integrated to form the basis...

Component-oriented development establishes the building of software artifacts by means of connection of a collection of components, independently produced. The success of applying this development approach depends of the compatibility between connected component interfaces. That compatibility includes interface structural and behavioral features. Component Interface Pattern establishes a struct...

The demand for high quality, large scale knowledge based systems has increased to the point where great improvements in knowledge engineering technology are needed. Library based approach for knowledge reuse is one of the widely exploited approaches, but there are two obstacles to this approach: the indexing problem, and the configuration problem. The real cause of these problems is the high le...

This paper presents a new approach to building software for embedded systems, based on the use of components in combination with contracts. The contracts specify the non-functional (resource) requirements of the different components in the system. This is especially important in embedded systems, since these systems are resourceconstrained. Our approach includes tool support for building embedd...

Historically, the success of automation has relied on two factors. The first is an understanding of the assembly process, first discovered and performed by hand, then captured, studied, and expressed in a technology. The second factor is the standardization of component properties. The standardization of component properties creates a marketplace in which many vendors can create components comp...
