This paper proposes a methodology that incorporates the process of attribute reduction in rough sets into crossover in genetic algorithms (GAs). We develop two algorithms on the basis of the methodology. The first one selects the crossover points either by attribute reduction or randomly; the second one selects the points only by attribute reduction and no crossover otherwise. We study 0/1 knapsack...
Sometimes failure analysis had to deal with the situation of the failure passing at room temperature but failing at high temperature, so that it was necessary to develop analyzing skills at high temperature. This paper introduced a special case fail at high temperature. By applying self heating method to obtain high temperature condition, the FA process of this case was described in detail. Finally...
Thin film transistors for large-area and/or flexible electronics desire materials with the maximum carrier mobility while maintaining a reasonable deposition temperature. Semiconducting oxides including polycrystalline ZnO and amorphous IGZO have emerged as important candidates for thin film transistors due to their relatively high carrier mobility (~10cm2/Vs) in comparison to amorphous silicon and...
While the emerging cloud computing systems promise infrastructure resources to support application scalability, there are publications of systematic evaluation of this emerging information technology infrastructure in general, and no obvious publications for some representative collaboration applications in particular. We describe a methodology to study the characteristics of distributed cloud computing...
Performance of statistical machine translation (SMT) systems relies on the availability of a large parallel corpus which is used to estimate translation probabilities. However, the generation of such corpus is a long and expensive process. In this paper, we introduce two methods for efficient selection of training data to be translated by humans. Our methods are motivated by active learning and aim...
In this paper, a small CPW-fed modified Sierpinski gasket monopole antenna operating with three bands for IEEE802.11 WLAN applications has been proposed and a constructed prototype has been implemented and tested. Measurement results indicate that the designed compact antenna, only 14 mm height and 26 mm width, can provided good bandwidth characteristics. At 2.45 GHz, 5.2 GHz and 5.8 GHz, the monopole...
