Research ArticleOpen accessIn the abstractDynamic Behavior of Tyre Tread BlockK. Sridharan, R. SivaramakrishnanThe Tyre tread pattern is the arrangement of blocks, grooves and voids, sipes and channels designed into the tread to enhance its grip on the road. Tread is the uppermost part of any tyre which contact into the road and it has its own performance towards mileage, traction, low noise and heat built up properties. It would be meaningful to … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 28 Jul 2012 · 9,798 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcoustic Properties of Innovative Material from Date Palm FibreLamyaa Abd AL-Rahman, Raja Ishak Raja, Roslan Abdul Rahman, Zawawi IbrahimProblem statement: An organic material is one of the major requirements to improve living environment and the invention of materials need to consider for the best solution. This study presents an experimental investigation on pure porous from Date Palm Fibre (DPF). The effectiveness of sound absorbers depends on structural architecture of this material. This study was conducted to examine the … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 17 Jul 2012 · 8,099 accessesView PDFCite
Research ArticleOpen accessIn the abstractToxicity of Industrial Wastewater Acting Singly or in Joint-Ratios on Clarias gariepinusAina Olubukola Adeogun, Azubuike Victor ChukwukaFreshwater ecosystems were the most vulnerable to pollution due to their easy accessibility for disposal of wastewaters leading to deterioration of water quality. Ona river, Ibadan, Nigeria is part of a dense network of inland watercourses emptying into the Lagos lagoon and receives industrial effluents from a food and beverage industry. The single and joint-action toxicity of effluents from these … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 18 Jun 2012 · 7,028 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrated Electricity Planning Comprise Renewable Energy and Feed-In TariffHo Wai Shin, Haslenda HashimProblem statement: Mitigation of global warming and energy crisis has called upon the need of an efficient tool for electricity planning. This study thus presents an electricity planning tool that incorporates RE with Feed in-Tariff (FiT) for various sources of Renewable Energy (RE) to minimize grid-connected electricity generation cost as well as to satisfy nominal electricity demand and CO2 emission … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 28 Feb 2012 · 8,701 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Hybrid Network (Wired and Wireless) Intrusion Detection using Statistical Data Streams and Detection of Clustered AlertsP. Thangaraj, M. ThangavelProblem statement: Wireless LAN IEEE 802.11 protocols are growing rapidly and security has always been a concern with the security of wired network. Wireless networks encountered threats from unauthorized access to network resources, installation of access points and illegal sniffing (refer as classical intrusion threats). In its current hybrid wired and wireless network attacks on the generally distinguish from normal … …Journal of Computer Science, Vol. 7, Issue 9 · 30 Jul 2011 · 7,169 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Compression on the Acoustic Absorption of Coir FiberMohd Jailani Mohd Nor, Md. Ayub, Rozli Zulkifli et al.Problem statement: The absorption characteristics of coir fiber were analyzed previously. Analytical method to predict the acoustical behavior of coir fiber has already been developed. However, compression effects of coir fiber were not explored which might significant for acoustics absorption during seat padding. In this study, compression effect on the sound absorption characteristics of coir fiber are demonstrated based on … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 8,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling Heterogeneity in Phase II Clinical TrialsChristopher N. Barnes, Shesh N. RaiProblem statement: The common assumption in non-randomized Phase II clinical trials is a homogeneous population with homogeneous response. This assumption is at odds with many trials today; a heterogeneous response due to the existence of subgroups. Approach: In order to examine the effects of heterogeneity on the trial outcome, a systematic platform is developed to quantify the range and classes … …Current Research in Biostatistics, Vol. 1, Issue 1 · 30 Jun 2010 · 10,131 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatistical Optimization of Fermentation Conditions for Cellulase Production from Palm Oil Mill EffluentJamal I. Daoud, Md. Zahangir AlamProblem statement: Palm oil mill effluent discharged by the oil palm industries is considered as the mixed of high polluted effluent which is abundant (about 20 million tonnes year-1) and its effect contributes to the serious environmental problems through the pollution of water bodies. Approach: The aim of this study was to identify the potential of low cost substrate such … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 8,196 accessesView PDFCite

Research ArticleOpen accessIn the abstractDesign of Multi-Valued Quaternary Based Analog-to-Digital ConverterA.H.M. Zahirul Alam, Wahab Adetunji Lawal, Sheroz Khan, Muhammad Mahbubur RashidProblem statement: The design of multi-valued quaternary based Analog-to-Digital Converter (ADC) circuit was presented. The ADC generates multi-valued logic outputs rather than the conventional binary output system to overall reduction in circuit complexity and size. Approach: Design was implemented using pipeline ADC architecture and was simulated using model parameters based on standard 0.13 µm CMOS process. Results: Performance analysis of … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,295 accessesView PDFCite
