Research ArticleOpen accessIn the abstractDynamic Synthesis of a Classic, Manual GearboxRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuToday, various types of gearboxes have been introduced into the vehicles to change the way the classic manual gearboxes work, such as automatic gearboxes, semi-automatic, continuous variable, dual-clutch automatic gearboxes etc. However, most gear shifters for in-service vehicles are still classical manuals, which is why their optimal synthesis based on their dynamics and especially on optimal performance is now more … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 30 Apr 2018 · 8,634 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Analysis of Bipolar Plate for 500w Pem Fuel Cell StackA. Kalaiyarasan, C. Srinivasan, S. SundaramThe PEM Fuel Cell (PEMFC) performance depends on the operating parameters like temperature, pressure, stoichiometric ratio of reactants, relative humidity, back pressure on anode and cathode flow channels, and the design parameters like rib width to channel width (L:C), channel depth, shape of the flow channel and number of pass on the flow channel. The voltage and power produced by … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 13 Jan 2018 · 7,895 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Simulation and Optimum Operation Strategy of a Trigeneration System Serving a HospitalFrancesco Calise, Massimo Dentice d'Accadia, Luigi Libertini et al.This paper presents a numerical analysis of a trigeneration system in a hospital, aiming at determining the cost-optimal operating strategy as a function of the energy demands to be matched. The system includes: A natural gas fired reciprocating engine, heat exchangers for waste-heat recovery, a single-stage LiBr-H2O Absorption Chiller (ACH), a cooling tower, pumps, a backup boiler, a backup vapour-compression … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 29 Aug 2016 · 8,177 accessesView PDFCite
Research ArticleOpen accessIn the abstractDo Firm Size and Financial Performance Affect Corporate Social Responsibility Disclosure: Employees' and Environmental Dimensions?Mohammad Ebrahim NawaisehThe paper empirically tests the impact of company size and financial performance on Corporate Social Responsibility Disclosure (CSRD), from the Employees' and Environmental Dimensions perspective with reference to the disclosure frequency and quality of these dimensions among Jordanian industrial public share holding companies; whether there is an impact of firm size measured by total assets, ROA, ROE and Leverage on … …American Journal of Applied Sciences, Vol. 12, Issue 12 · 29 Nov 2015 · 8,326 accessesView PDFCite
Research ArticleOpen accessIn the abstractDYNAMIC MODELING AND GAIN SCHEDULING CONTROL OF A CHIILLED WATER COOLING SYSTEMJun Liu, M. ZaheeruddinA dynamic model of a Chilled Water (ChW) cooling system with a stratified ChW tank was developed. A PI-based Gain Scheduling (GS) control strategy was designed to improve thermal performance of the chiller system. Five different operation strategies were simulated and the energy consumption and cost of operating the system under full load and partial load conditions were compared. The … …Energy Research Journal, Vol. 5, Issue 1 · 15 Oct 2014 · 7,010 accessesView PDFCite
Research ArticleOpen accessIn the abstractWINDOWS WEB PROXY CACHING SIMULATION: A TOOL FOR SIMULATING WEB PROXY CACHING UNDER WINDOWS OPERATING SYSTEMSWaheed Yasin, Hamidah Ibrahim, Nur Izura Udzir, Nor Asilah Wati Abdul HamidWeb caching plays a key role in improving the performance of the web by reducing the latency of delivering web objects to the users. On the other hand, a simulation tool plays a key role in studying the behavior of any network such as studying the effects of web caching on the performance of the network. The aim of this … …Journal of Computer Science, Vol. 10, Issue 8 · 7 Mar 2014 · 10,971 accessesView PDFCite
Research ArticleOpen accessIn the abstractSECURITY BREACH IN TRADING SYSTEM-COUNTERMEASURE USING IPTRACEBACKM. P. Rajakumar, V. ShanthiRecently, economic scenario is often facing security breach that has heavy impact on the financial soundness of a company particularly, stock prices on firms. The utmost consequence being the whole business comes to a standstill.
