Research ArticleOpen accessIn the abstractWeed Detection over Between-Row of Sugarcane Fields Using Machine Vision with Shadow Robustness Technique for Variable Rate Herbicide ApplicatorA. Muangkasem, S. Thainimit, R. Keinprasit, T. IsshikiProblem statement: Uniformly herbicide rate is used as a conventional practice in Thailand for controlling weeds in sugarcane fields. Since weeds usually grow in certain areas with non-uniformly distribution, uniform herbicide rate approach is not suitable and non-sustainable agricultural technique both in terms of economic an environmental aspect. To address these issues, Variable Herbicide Rate (VHR) was introduced. The VHR … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 8,238 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Application of Ionic Liquids in Catholic Coupling of AcetophenonePo-Chung ChengProblem statement: The cathodic coupling of acetophnone was carried out in aqueous solutions containing sodium sulfate and 1-Octyl-3-Methylimidazolium Chloride ([OMIM]Cl) as supporting electrolytes. [OMIM]Cl is an ionic liquid, also serving as a co-solvent to prevent the deposition of products during electrolysis. The products are extracted with ether after electrolyses. Approach: It is shown in this study that the recycling of … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,043 accessesView PDFCite
Research ArticleOpen accessIn the abstractObject Based Middleware for Grid ComputingS. Muruganantham, P. K. Srivastha, KhanaaProblem statement: "Grid" computing has emerged as an important new field, distinguished from conventional distributed computing by its focus on large-scale resource sharing, innovative applications and, in some cases, high-performance orientation. The role of middleware is to ease the task of designing, programming and managing distributed applications by providing a simple, consistent and integrated distributed programming environment. Essentially, middleware is … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 7,344 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Prototype Design for Enhancing Customer Trust in Online PaymentsThair Al-Dala’in, Peter Summons, Suhuai LuoProblem statement: The adoption of mobile device technology can contribute significantly to enhance customers trust in online payment systems. Approach: The perceptions and preferences of online shoppers are influenced by several key factors which serve to both enhance and compromise this trust and in turn affect a customer intentions and behavior in relation to use online payment systems. The first … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,066 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fragile Watermarking Scheme for Image Authentication with Tamper Localization Using Integer Wavelet TransformP. MeenakshiDevi, M. Venkatesan, K. DuraiswamyProblem statement: In recent years, as digital media are gaining wider popularity, their security related issues are becoming greater concern. Method for authenticating and assuring the integrity of the image is required. Image authentication is possible by embedding a layer of the authentication signature into the digital image using a digital watermark. In some applications tamper localization is also required. … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 7,734 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of the Tunnel Boring Machine Advancement on the Bologna-Florence Railway LinkM. Cardu, P. Oreste, T. CicalaProblem statement: The high-velocity railway link between Bologna and Firenze (Italy) is today under construction and several tunnels have to be excavated for this purpose, some of these using TBMs. A small diameter tunnel, named Cunicolo ginori, was realized by TBM parallel to a large railway tunnel (Vaglia), at the distance of only 35 m. Approach: The Vaglia tunnel had … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Sep 2009 · 7,969 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

HalimProblem Statement: Electrical and magnetoresistive properties of the Nd doped (La1-xNdx)0.5Ba0.5MnO3 type samples with 0 ≤ x ≤ 1.0 had been prepared using the solid state reaction. These materials are extensively studied by the substitution of rare-earth compound is to understand the nature of transport phenomena in each system. Approach: The samples were calcined at 900°C for 12 h, pelletized … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,666 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of the Ant Colony Search Algorithm to Reactive Power Pricing in an Open Electricity MarketA. Ketabi, A. Ali BabaeeDeveloping an accurate and feasible method for reactive power pricing is important in the electricity market. In conventional optimal power flow models the production cost of reactive power was ignored. In this study, the production cost of reactive power was comprised into the objective function of the OPF problem. Then, using ant colony search algorithm, the optimal problem was solved. … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,265 accessesView PDFCite
