A p-type ethanol sensor with a response time of ∼ 8.3s at room temperature was produced by SnO2:Sb nanowires. The electrical properties of p-type SnO2 nanowires are stable with a hole concentration of 1.544 × 1017cm- 3 and a field-effect mobility of 22cm2V-2S-1. X-ray photoelectron spectroscopy (XPS) and Hall measurement revealed that as-synthesized nanowires exhibit p-type behavior. A comprehensive investigation of the p-type sensing mechanism is reported. © 2010 IOP Publishing Ltd.

Learning effect in scheduling problems has received growing attention since Biskup [3] introduced the position-based model, where the learning curve is expressed as a power function of a job position. Hurley [11] pointed out that the actual processing time of a given job drops to zero precipitously as the number of jobs increases in the standard power model. Moreover, the learning rates show considerable variation within industries or firms. The variation extends not only across firms at a given time, but also within firms over time. For instance, the learning curves usually have an initial downward concavity, and no further improvements are made after some amount of production. Beside the standard power model, learning curve is seldom discussed in scheduling. In this paper, we offer a surprising simple yet realistic learning effect model which has the flexibility to describe different learning curves easily. For instance, the standard power model, the well-known S-shaped and the plateau functions are special cases of the proposed model. We then present the optimal solution for some scheduling problems. © 2011 Elsevier Inc. All rights reserved.

To achieve national CO2 emission reduction targets, the Taiwanese government is planning to adopt policies, such as feed-in tariffs (FITs) and capital subsidies, in order to attract the public as well as companies to invest in and use solar photovoltaic (PV) systems. However, a huge budget is necessary for the government to implement such policies. Therefore, it is important that it fully recognizes which policy, or combination of policies, promoting solar PV applications has the greatest economic benefit. This study uses the system dynamics approach to develop a simulation for assessing these promotion policies. Using this simulation system, policymakers can carry out cost/benefit analyses for different combinations of promotion policies, CO2 emission reduction goals, and budget limitations. In addition, the simulation scenarios include different FIT prices, subsidies, and upper limits of annual ROI (return of investment). The simulation period is from 2011 to 2030. We find that when adopting only FITs or capital subsidies with a fixed upper limit of ROI, increasing the FIT price or subsidy is a good approach. When the upper limit of ROI is fixed, the effect of different combinations of FIT prices and subsidies on the accumulation of solar PV applications is insignificant. Nevertheless, the promotion policy with the higher subsidy and lower initial FIT price has a lower average cost of CO2 emission reduction. © 2012 Elsevier Ltd.

Forecasting the long-term load in a country is a critical task for the government. In addition, establishing a precise upper bound for the long-term load avoids unnecessary power plant investment. For these purposes, a collaborative fuzzy-neural approach is proposed in this study. In the proposed approach, multiple experts construct their own fuzzy back propagation networks from various viewpoints to forecast the long-term load in a country. To aggregate these long term load forecasts, fuzzy intersection is applied. After that, a radial basis function network is constructed to defuzzify the aggregation result and to generate a representative/crisp value. The practical case of Taiwan is used to evaluate the effectiveness of the proposed methodology. According to the experimental results, the proposed methodology improved both the precision and accuracy of long term load forecasting by 40% and 99%, respectively. In addition, the proposed methodology made it possible to accurately forecast the average and peak values of the annual energy consumption at the same time. © 2011 Elsevier Ltd. All rights reserved.

This study proposes a two-field driving scheme for field sequential color liquid crystal displays (LCDs) without color filters. The proposed scheme is based on angularly positioned color LEDs. In each fieldthe angular rays of two colors are collimated by a collimation lens, redirected by a light guideand converged by a cylindrical-lens array to map into corresponding sub-pixel positions to efficiently display color images. The three main advantages of this approach are the elimination of dye color filtershigh feasibility using conventional ultra-precision machining processesand a larger color gamut. © 2012 Optical Society of America.
