During the operation of lithium-ion batteries, unexpected heat could be generated, which reduces the energy storage capacity as well as the longevity of the batteries. A unique cooling strategy involving an oscillating heat pipe is suggested as a solution to this study. The cooling channel is mounted on the outside of the battery module since electric vehicles have a little amount of space. This work used ANSYS/Fluent to build a lithium-ion battery model for a rectangular cell and evaluate its performance using the cooling system on the battery cell. The heat generated in the flow direction was absorbed by air-fluid throughout the cooling process, which decreased the cooling capacity. The temperature downstream is therefore always higher than the temperature upstream. In this process, the temperature varies from 288 K to 292 K. . In this study, the temperature of the battery rises quickly in the absence of a cooling system while rising gradually in the presence of one. As a result, the cooling system helped to provide a better outcome.

The purpose of this paper is to present and evaluate a tool designed to assess the performance of military teams participating in complex military training exercises and to investigate the effectiveness of simulator training and live training from the matching of inherent stressors. Specifically, this study evaluates a tool that has been used by Norwegian military subject matter experts (SMEs) to assess the performance of eight cadet teams at the Royal Norwegian Naval Academy (RNoNA) during two separate 4-hour simulator exercises and a 48-hour live exercise. The resulting positive Spearman rank correlation coefficients between team performance assessments in the simulator exercises and the live exercise were strongest when the simulator scenario emphasized the stressors inherent in the live exercise and weakest when the simulator scenario did not facilitate the task demands in the live exercise. The study showed that (1) team performance measured in simulator training exercises can predict performance in a subsequent live training exercise, and (2) that scenario-based simulator training can realistically and effectively represent training demands for live operations. Our findings show the RNoNA tool can be easily applied to team training exercises and provide a meaningful evaluation of a team's future performance.

Introducing RFID technology into retail industry enhances and increases the speed, accuracy, detailing and visibility of operational information updates for specific units of business production. This research examines the impact of RFID technology on supply chain (SC) performance. It focuses on RFID technology and its implementation at two retail chains in the United States (US) and Europe which have successfully implemented this technology, and identifies the impact of RFID technology on improving SC performance in the retail industry. This study has examined a wide range of research literature and secondary data sources. The researcher has concentrated on both explorative and indicative studies in an effort to understand the impact that the adoption of RFID technology will have on improving the performance of the SC by comparing two different case studies. This study has found that coordination and integration operations are important for inventory management and related operations and they are also important factors which contribute to performance improvement in both case studies. In addition, this study has found that RFID’s information-sharing support for buyers in the SC has promoted the accuracy of purchasing forecasts. Finally, it is found that RFID has provided increased flexibility of operations, using smart shelves and reducing the cost of inventory management. This study concludes that the implementation of RFID technology helps retail SC perform the operational process as well as resource visualisation. A limitation of this research was the use of secondary sources rather than the adoption of a primary data collection approach, which latter would have provided a real-time representation of current RFID implementation. Future research could focus on the comparison of three or four case studies in order to arrive at more detailed and supported recommendations.

We report the synthesis and characterization of a series of new mesoporous zeolite and zeotype materials made available by combining new and improved procedures for directly introducing carbon into reaction mixtures with the fluoride route for conventional zeolite synthesis. The mesoporous materials were all prepared by hydrothermal crystallization of gels adsorbed on carbon matrices which were subsequently removed by combustion. The procedures presented here resulted in mesoporous zeolite and zeotypes materials with MFI, MEL, BEA, AFI and CHA framework structures. All samples were characterized by XRPD, SEM, TEM and N-2 physisorption measurements. For the zeolite materials it A as found that mesoporous MFI and MEL structured single crystals could indeed be crystallized from fluoride media using an improved carbon-templating approach. More importantly, it was found that mesoporous BEA-type single crystals could be crystallized from fluoride media by a newly developed procedure presented here. Thus, we here present the only known route to mesoporous BEA-type single crystals, since crystallization of this framework structure from basic media is known to give only nanosized crystals as opposed to mesoporous single crystals. For the zeotype materials it was found that highly crystalline mesoporous materials of AFI and CHA structure types could be synthesized using a newly developed procedure. (c) 2006 Elsevier Inc.

It has recently become very popular to feedforward the input signal in wideband delta-sigma modulators, so that the integrators only process quantization errors. The advantage is that the actual signal is not distorted by op-amp and integrator nonlinearities. The paper applies this technique to single amplifier based sigma delta modulator in both analog and digital way. Their characteristic has been analyzed and simulation results are given which show the improved performance., QC 20141205

Softening-melting (SM) experiments have been carried out by using sinter basicity (CaO/SiO2) 1.74 to 2.09 and alumina content 2.90 to 3.39%. The objective of the work is to find the relation between sinter basicity and alumina on SM temperature range, so that we can improve the furnace performance. The increase in basicity of sinter from 1.74 to 2.09 at alumina 2.90 decreases softening start temperature and increases melting finish temperature. Thus, there is a rise in the SM temperature range from 192 to 245 degrees C which increases the gas flow resistance and reduces the permeability across the cohesive zone and deteriorating furnace performance, whereas on the other hand, with an increase in basicity from 1.74 to 2.09 at alumina 3.39, it decreases both softening start temperature and melting finish temperature. Thus, there is a decrease in the SM temperature range from 230 to 220 degrees C, which shows a slight improvement in gas flow resistance.
