For low-concentration solar applications, v-reflectors are attractive choice to collect sunlight since they are simple to build with reduced manufacturing cost and technical requirements. In this paper, with the account for the power evolution of all possible reflection modes, careful modeling for the concentration ratio of such collectors was achieved and optimized by numerical methods in order to determine the optimal apex-angle that facilitates maximum utilization of the solar energy. The outcome of this research is interesting since it provides a useful recipe for an optimal design of v-reflectors that can be found in various solar applications.

The purpose of this study is to analyse, by simulation, the injection of ABS plastic parts and track results on piece deformations after the latter was removed from the mould. Injection Process. Analysis was performed using the Autodesk Moldflow professional package. The results of the theoretical analysis by numerical methods are used for optimal design of the die to reduce and eliminate the strains and defect parts.

Design Construction

This study suggests the design construction process of green buildings based on the construction process for green buildings in Korea. In this construction process, the planning purpose lies in the CO2 reduction of each element technology not considered during the general building construction processes and energy saving construction processes and that of overall buildings. The interaction of each element technology was considered so that evaluation and feedback could be provided at each stage. Different from existing construction processes, CO2 reductions were evaluated and fed back at each stage and alternative designs could be selected to draw the optimal design.

Design Construction

The starting point of search is an important factor in optimal design construction as a poor starting point may require a longer time before convergence is reached. Hence the location of the initial design points for use in the Quick Convergent Inflow Algorithm on segmented regions is examined with the aim of developing useful criteria for identifying the initial design points. Proportional allocation of design points to go into the initial design measures is proposed. The allocation of 100% vertex points, 100% boundary points and 100% boundary points as well as the allocation of 50% vertex and 50% boundary points, 50% vertex and 50% interior points and 50% interior and 50% boundary points are investigated. Results show that a combination of design points comprising of 50% vertex points and 50% interior points or 50% vertex points and 50% boundary points forms helpful rules in identifying the initial design points for use in the Quick Convergent Inflow Algorithm. With these combinations, a moderate number of iterations needed to reach the required optimal or near-optimal solution is maintained.
