This paper presents a human reliability analysis (HRA) model for allowing the incorporation of elements that represent the facility conditions in determining human error probabilities (HEP) used in probabilistic safety analyses of process plants. It is based on an approach presented in an earlier paper by the same authors and the difference is that the model has been implemented in a Bayesian network and run by means of the Netica™ tool. The results in terms of HEPs are the same as those of the earlier paper and a sensitivity analysis was performed by means of the network developed.

Self-cleaning surfaces have excelled in recent years in energy and environmental fields. In particular, in solar energy area, these surfaces are used to avoid soiling accumulation on photovoltaic (PV) modules. So far TiO₂ has been widely used due to its photocatalytic activity and photo-induced superhydrophilicity. However, this oxide has some limitations since it reduces the glass transmittance and it rapidly reestablish the water contact angle in dark environments. In order to circumvent these limitations, composites TiO₂/SiO₂ have been proposed. For photovoltaic application, besides a good transparency in the wavelength region 300–1800 nm and self-cleaning properties, the coating should also present long durability and adequate adhesion to endure the outdoor conditions. Aiming at developing a coating with these properties, in this work, TiO₂/SiO₂ composites containing different titanium content have been synthesized and compared with pure TiO₂ films in relation to adhesion, transparency and hydrophilicity. Both films have been deposited over low iron float glass substrates by sol–gel dip-coating technique and different calcination temperatures (400, 500, 600°C) and Si/Ti molar rates (Si₈₆Ti₁₄, Si₄₀Ti₆₀) have been considered. TiO₂/SiO₂ films showed higher transmittance in visible range compared with pure TiO₂. TiO₂/SiO₂ films showed superhydrophilic character before and after ultraviolet irradiation, with water contact angles near to 0°. Furthermore, as predicted, TiO₂/SiO₂ films could keep the superhydrophilic character in dark environments, in contrast with pure TiO₂ films. Both TiO₂ and TiO₂/SiO₂ films exhibited good adherence and it is shown that higher calcination temperatures and higher titanium content enhance such property. All f

This paper propose a driving assistance scheme for a powered wheelchair with a force feedback function of its joystick. Generally, a powered wheelchair moves in a human coexistence environment such as a pedestrian way and it is important to move on these environments without a feeling of oppression to other people around it. Therefore, we propose a concept of a dynamic personal space which is a region surrounding a person who can feel comfortable psychologically to other person with a moving wheelchair in the pedestrian flows. A dynamic personal space is defined considering with a relative velocity and acceleration between the powered wheelchair and the pedestrians around it. Using this concept, we develop a driving assistance system using a force feedback of its joystick, which enables the powered wheelchair to move in a human coexistence environment without a feeling of oppression on other people. In this paper, we investigate spatial relationship with a powered wheelchair experimentally and define a dynamic personal space using these results. For verifying its effectiveness, the performance of our system is verified by experiments using our prototype. © 2014 IEEE.

A robust fuzzy control design, with time delay, based on gain and phase margins specifications for nonlinear systems, in the continuous time delay, is proposed. From input and output data of the process, a Fuzzy C-Means (FCM) clustering algorithm estimates the antecedent parameters and the rules number of a Takagi-Sugeno fuzzy model, whereas the least squares algorithm estimates the consequent parameters. A multiobjective genetic strategy is developed to tune the fuzzy digital controller parameters, so the gain and phase specified margins are obtained for the fuzzy control system. The fuzzy PID controller was implemented on a real time acquisition data platform, based on CompactRIO (NI cRIO-9073) and Lab VIEW, from National Instruments, for temperature control of a thermic process. The experimental results show the efficiency of the proposed methodology through the accuracy in the gain and phase margins of the PID control system compared to the specified ones and tracking of the reference trajectory. Fuzzy PID controller also is more efficient when compared to the fuzzy delay and lead compensator.

Food Waste to Bioenergy via Anaerobic Processes

Energy Procedia 2014年 61卷 307-312页

作者： Thi Ngoc Bao Dung Biswarup Sen Chin-Chao Chen Gopalakrishnan Kumar Chiu-Yue Lin Department of Environmental Engineering and Science Feng Chia University Taichung 40724 Taiwan Green Energy Development Centre Feng Chia University Taichung 40724 Taiwan Master's Program of Green Energy Science and Technology Feng Chia University Taichung 40724 Taiwan Department of Landscape Architecture ChungChou University of Science and Technology Changhua County 510 Taiwan Department of Environmental Engineering Daegu University Gyeongsan Gyeongbuk 712-714 Republic of Korea

The value of food waste has not been paid much attention due to the lack of application policies and suitable management laws. In this paper the food waste management in the prospect of bioenergy production and the future directions has been reviewed. The official data in relation to food waste generation and current status of food waste management were collected from 21 countries. The bioenergy production potential of food wastes from these countries has been calculated by applying five different innovative methods of bioenergy production. The bioenergy potential based on anaerobic digestion for bio-methane (Method I), two-phase process for bio-hythane (Method II), three-stage fermentation for bio-methane (Method III), two-step process of dark-fermentation and photo-fermentation for bio-hydrogen (Method IV), and three-stage fermentation for bio-hythane (Method V) were about 379,796 KWh/year, 102,137 KWh/year, 76,743 KWh/year, 833,555 KWh/year and 141,739 KWh/year, respectively. By evaluating the bioenergy potential of these anaerobic processes, the appropriate strategy and related management policy were suggested. Besides, this study provides a hierarchical vision for food waste management which would lead towards the sustainable development.

Enhanced Electrical and nuclear Radiation Detection Performance in BiI3 Wide Bandgap Semiconductor Detectors

引用

ECS Meeting Abstracts 2014年第41期MA2014-01卷

作者： HyukSu Han Minki Hong Sasmit S. Gokhale Susan B. Sinnott James E. Baciak Juan C. Nino Department of Materials Science & Engineering University of Florida Department of Materials Science & Engineering Nuclear Engineering Program University of Florida

BiI3 is a wide band-gap compound semiconductor with a high effective atomic number that is anticipated to exhibit higher detection efficiency than other compound semiconductors such as HgI2, PbI2, and CdZnTe. This makes BiI3 of particular interest for moderate and high energy gamma-ray detection applications. However, the low resistivity of BiI3 results in high leakage currents and degrades the electrical properties and detecting performance of the detectors. Here we show that the main reason for the low resistivity in BiI3 is due to the high volatility of iodine and the high concentration of intrinsic Schottky defects. Furthermore, we will discuss novel defect engineering strategies that successfully mitigate the obstacles associated with iodine vacancies in the material. Density functional theory (DFT) calculations, as well as experimentally measured electrical properties, and radiation response will be presented for undoped and Sb-doped BiI3 (SBI) single crystals grown via the vertical Bridgman growth technique. Most importantly, we will demonstrate the first ever recorded gamma-ray spectrum using BiI3-based detectors.
