Improving Blue InGaN Laser Diodes Performance with Waveguide Structure Engineering

To enhance lasers’ power and improve their performance, a model wasapplied for the waveguide design of 400 nm InGaN/InGaN semiconductor laser, whichis much easier to implement. The conventional and new laser structures weretheoretically investigated using simulation software PICS3D, which self-consistentlycombines 3D simulation of carrier transport, self-heating, and opt...

Improving Engineering Data Management with Semantic Web Techniques

Throughout the IT communities, it has been acknowledged that ontology plays a key role in representation and reuse of knowledge. This paper discusses some issues of ontology construction for engineering data management, such as knowledge discovery, knowledge representation and semantic services. All discussions are followed by a running example of engineering data management. Based on the user ...

Improving the velocity tracking of cruise control system by using adaptive methods

Accurate and correct performance of controller in cruise control systems is important. Hence, in such systems, controller should optimize itself against noise and probable changes in system dynamic. As a matter of fact, in this article three approaches have been conducted to-ward this purpose: MIT, direct estimation and indirect estimation. These approaches are used as controllers to track refe...

Requirements Engineering for Improving Business/IT Alignment in Security Risk Management Methods

Information systems (IS) security within organizations is more and more focused around risk management approaches. Central to these approaches is the need for a better understanding of the required alignment between the business view of the organization and the architecture of its underlying IS. Through the use of requirements engineering techniques, the paper suggests how this business/IT inte...
