Various evolutionary algorithms are being developed to search the optimal solution of various problems in the real world. Evolutionary algorithms search solutions showing the optimal fitness to given problem using their own operators. Engineering benchmark problems can be used for performance measurement of evolutionary algorithms, and the water distribution network design problem is one of the widely...
A simplified approach to analysis of finite and curved conductor-dielectric periodic (CDP) screen is proposed. The contribution of the element in the real structure is estimated by that of the elaborately constructed virtual infinite planar CDP structure. The analytic results based on Floquet theorem are useable for the proposed approach thus high efficiency and accuracy are obtained. The calculated...
Green chemistry is a systematic scientific and engineering approach that seeks to reduce the use of hazardous chemicals and the generation of toxic wastes by changing how society designs, manufactures, and uses chemicals in processes and products. Rather than managing wastes after end-of-product life, green chemistry shifts our focus to designing chemicals, processes, and goods that have less or no...
Campus networkpsilas Internet accessing traffic is complicated, non-linear and periodical. Our goal is to give out a engineering approach to prediction of network traffic based time-series analysis model (EPTS) for campus exit-link. In our EPTS with rate-limiting, we configure rate limit based interface, then use time-series decomposed model, give out the linear trend component, periodical component,...
In today's continuously changing markets newly developed products often do not meet the demands and expectations of customers. Research on this problem identified a large gap between developer and user expectations. Approaches to bridge this gap are to provide the developers with better information on product usage and to create a fast feedback cycle that helps tackling usage problems. Therefore,...
An improved cost proxy model is established in the following, where the extreme imbalance between urban and rural area as well as complicated geographic environment of China was taken into consideration. On the one hand, new parameters were introduced into scene variant vector so as to prescribe urban and rural differences and also topographical differences. On the other hand, in order to analyze...
Prediction of acoustic noise radiated by electric motors is nowadays important both for machine manufacturers and users. This paper describes an engineering approach to prediction of noise of magnetic origin produced by permanent magnet (PM) brushless motors. The sound power level (SWL) is calculated on the basis of magnetic field analysis in the air gap, radial forces, natural frequencies of the...
This paper discusses practices for risk assessment from different application domains and proposes an engineering approach towards risk assessment starting from user requirements. A new approach for a semi-quantitative risk assessment method based on sound engineering principles is proposed.
