This article studies the GIS simulation of yearly power generation in five different tidal stations in the East Coast region of Malaysia. The tidal stations are Geting, Tanjung Gelang, Tioman, Tanjung Sedili and Cendering. The tidal station in Geting is not analysed in this study because the tidal range is insignificant. After analysing the lagoons nearby to the four tidal stations, Tanjung Gelang and Tanjung Sedili are chosen in this study based on their natural characteristics and geomorphology of lagoons. The simulation model is based on yearly power generation using tidal barrage. This article also looks into the model in terms of mapping using GIS software to obtain bathymetry and tidal range data. Bathymetry data in GIS format is obtained from NOAA (National Oceanic and Atmospheric Administration) and tidal range data is obtained from ‘Jabatan Ukur dan Pemetaan Malaysia’. The latest tidal data up to date is the year 2011. The minimum depth of tidal basin should be 3.0 meter. Using GIS software to analyse bathymetry and tidal range data, the results are then combined to find yearly generation power output in the two tidal stations and are plotted in one map for each tidal station. The area of basin in Tanjung Gelang and Tanjung Sedili are 17.736 km2 and 27.919 km2. The calculation includes the important parameters such as area of basin, tidal range, number of tide cycles per year, and number of hours per tide. From the results and analysis, it is concluded that Tanjung Sedili and Tanjung Gelang produce 1.528 x 108 kWh and 1.294 x 108 kWh as their yearly power generation in 2011.

Influence of Engine Cabin Simplification on Aerodynamic Characteristics of Car
Authors: Hu Xing Jun , Chang Jing
Published: October 2014

In order to analyze the impact of engine cabin parts on aerodynamic characteristics, the related parts are divided into three categories except the engine cooling components: front thin plates (average thickness of 2mm), bottom-suspension and interior panels. The aerodynamic drag coefficient (Cd) were obtained upon the combination schemes consisting of the three types of parts by numerical simulation. Results show that Cd by simulation is closer to the test value gained by the wind tunnel experiment when front thin plates were simplified to the two-dimensional interface with zero thickness. The error is only 5.23%. Meanwhile this scheme reduces grid numbers, thus decreasing the calculating time. As the front thin plates can guide the flow, there is no difference on the Cd values gained from the model with or without bottom-suspension or interior panels when the engine cabin contains the front thin plates; while only both bottom-suspension and interior panels are removed, the Cd value can be reduced when the cabin doesn’t contain the front thin plates.

With the significant increase of write performance onto SSD, whether deduplication based on SSD could be a performance bottleneck of SSD comes to a spot worthy of our attention. To this end, this paper, firstly, performs an experiment on achieving deduplication via software method, and reveals that software-based deduplication decreases SSD's read and write performance. And then a hardware-based deduplication with details is proposed and implemented to accelerate deduplication using FPGA, and expected results are achieved. Finally, we come to the conclusion that hardware-based deduplication can not only guarantee read and write performance of SSD, but also save storage capacity and enhance endurance.

Authors: Zhang Jia Wei , Belouadah Rabah
Published: October 2014

This paper reports on a prototype of magnetic actuator which is based on generalized magnetoelectric (ME) phenomena. The tested sample was made up of a vertical piezoelectric bender coated with a silver plate and electric wire. Due to the coupling of the piezoelectric layer and Lorentz force in the metal part of the sample, piezoelectric bender’s torsion deformation can be induced by Lorentz force, and thus piezoelectric voltage appeared on the sample. Then, generalized magnetoelectric effect appeared when ac magnetic flux was across the thickness of the beam. Finally, without applying a power source on the specimen, a room temperature magnetic field actuator can be developed by using this piezoelectric beam, from which magnetoelectric voltage coefficient as high as 81.8 mV/cm-Oe can be obtained. In the experiments, the magnetoelectric voltage of piezoelectric beam can be controlled by adjusting ac current, so it is promising to be put into the application of magnetic field sensing and actuating technology.

Published: October 2014

According to the structure features of the piston, the method of combining application of finite element simulation and theoretical analysis was explored to determine the extrusion process program and the extrusion process parameters. Theoretical calculation shows that a longitudinal extrusion and a lateral extrusion can form piston. The result comparing simulative prediction with theoretical calculation demonstrates that there is a good fit between the two and the theoretical calculation is right. The result of simulative prediction demonstrates that the grain size of piston after extrusion is about 17.8 μm and the refining rate reaches 55%. The grain size on both sides of the piston skirt and piston internal floor place is about 27 μm, so the refining effect is less obvious than other parts. However, the grain refinement in the piston pin holes is more obvious, the grain is refined to 13 μm and the refining rate is about 67.5%.The result comparing simulative prediction with the experimental analysis demonstrates that there is a good fit in grain refinement between the two.

Published: October 2014

The fiber characteristics directly affecting the yarn tensile properties are analyzed and the features of GA-BP artificial neural network are presented. Based on the interrelationship among the fiber characteristics, which could led to a worse predicting result, Principal component analysis (PCA) is adopted to solve this problem. 12 characteristics of cotton fiber tested by HVI or AFIS and yarn process parameters, such as combing, degree of twist, yarn count, was preprocessed by this method and 10 independent comprehensive indexes are induced and substituted into GA-BP artificial neural network as input factors. For further comparison, the 10 dimension reduced indexes and the 15 initial variables are respectively introduced into the GA-BP and BP artificial neural network to develop 4 prediction models. By comparing the accuracy in predicting yarn tenacity, it is concluded that GA-BP model has higher accuracy than BP model, and the dimension reduced indexes based on PCA would decrease the accuracy in prediction instead. So, blindly using PCA method for reducing the complex correlation among input variables was not helpful for the prediction accuracy.
