Design and Implementation of a Novel HomePlug-Based Solution for Low Cost and High Performance Smart Home Networking

As the smart home is the end-point power consumer, it is the major part to be controlled in a smart micro grid. There are so many challenges for implementing a smart home system in which the most important ones are the cost and simplicity of the implementation method. It is clear that the major share of the total cost is referred to the internal controlling system network; although there are too many methods proposed but still there is not any satisfying method at the consumers’ point of view. In this paper, a novel solution for this demand is proposed, which not only minimizes the implementation cost, but also provides a high level of reliability and simplicity of operation; feasibility, extendibility, and flexibility are other leading properties of the design.

Computer-assisted Modelling and Analysis of Linear Programming Problems: Towards a Unified Framework

A framework for model formulation and analysis to support operationsand management of large-scale linear programs is developed fromthe combined capabilities of CAMPS and ANALYZE. Both the systemsare reviewed briefly and the interface which integrates thetwo systems is then described. The model formulation, matrixgeneration, and model management capability of CAMPS and thecomplementary model and solution analysis capability of ANALYZEare presented within a unified framework. Relevant generic functionsare highlighted, and an example is presented in detail to illustratethe level of integration achieved in the current prototype system.Some new results on discourse models and model management supportare given in a framework designed to move toward an ‘intelligent’system for linear programming modelling and analysis.     

Analysis and design of stereoscopic television systems

The performance of stereoscopic television systems and its dependence on various parameters are investigated. It is shown that the extent of the region of space which can be displayed in three dimensions without causing undue eye strain to the observer, and also the minimum detectable depth interval, are related to and may therefore be controlled by the system's geometrical and optical parameters. Distortion in three-dimensional images due to the difference between the depth magnification and the magnification of the xy-plane is also analysed. Finally, it is demonstrated that the expressions defining the relationship between the performance of a 3D television system and its various parameters form a useful basis for the design of a system of this type for a given application.
