Research ArticleOpen accessEvery word in the titleFluid-Solid Coupling Analysis on Evolution of In-Situ Stress Field by Water Injection in OilfieldJianjun Liu, Yongxiang Zheng, Bohu Zhang et al.Water injection in oilfield may break initial balance of reservoir and lead to re-distribute of stress and deformation of strata. For further research of the evolution characteristics of in-situ field by water injection, the influence on reservoir by water injection was analyzed and different variables were set to study the effects of depth, injection-withdraw ratio and elastic modulus on strain … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 6 May 2017 · 8,066 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAccessing the Appropriateness of a Spatial Regression Using Generalized (h1h2-)Slepian Random FieldWayan Somayasa, Jamhir Safani, La Ode Ngkoimani, Muhamad Zamrun F.In this study we derived asymptotic goodness-of-fit test (model check) for spatial regression where the critical region as well as the p-value of the tests are approximated based on the distribution of a type of the integral functional of the generalized (h1h2-)-Slepian field and the set-indexed Gaussian white noise. Such random fields are obtained as the limit process of the … …Journal of Mathematics and Statistics, Vol. 13, Issue 2 · 2 May 2017 · 7,364 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffectiveness of Thought Field Therapy Provided by Newly Instructed Community Workers to a Traumatized Population in Uganda: A Randomized TrialR. Howard Robson, Phyll M. Robson, Roger Ludwig et al.Thought Field Therapy (TFT) is a promising treatment for posttraumatic stress in a resource poor environment. This study further explores the benefits of this treatment in a rural population in Uganda, which had suffered from the psychological consequences of previous violent conflict. Thirty-six local community workers received a two-day training in TFT trauma intervention and treated 256 volunteers with symptoms … …Current Research in Psychology, Vol. 7, Issue 1 · 19 Feb 2016 · 16,841 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleON SELF-INVERSE BINARY MATRICES OVER THE BINARY GALOIS FIELDAli Muhammad Ali Rushdi, Fares Ahmad Muhammad GhalebAn important class of square binary matrices over the simplest finite or Galois Field GF(2) is the class of involutory or Self-Inverse (SI) matrices. These matrices are of significant utility in prominent engineering applications such as the study of the Preparata Transformation or the analysis of synchronous Boolean Networks. Therefore, it is essential to devise appropriate methods, not only for … …Journal of Mathematics and Statistics, Vol. 9, Issue 3 · 4 Sep 2013 · 7,251 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleApplication of Near Field Communication Technology for Mobile Airline TicketingWayan SupartaProblem statement: Near Field Communication (NFC) technology opens up exciting new usage scenarios for mobile devices based platform. Users of NFC-enabled devices can simply point or touch their devices to other NFC-enabled elements in the environment to communicate with them (‘contactless’), making application and data usage easy and convenient. Approach: The study describes the characteristics and advantages of NFC technology … …Journal of Computer Science, Vol. 8, Issue 8 · 12 Jul 2012 · 7,486 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleField Programmable Gate Arrays Based Realization of Truncated MultipliersMuhammad H. Rais, Mohammed H. Al MijalliProblem statement: Due to high cost and non reconfiguration of Application Specific Integrated Circuits (ASICs) in image processing applications, for example MPEG video compression used in CT scan frames requires real time conditions and the algorithms should be verified and optimized before implementation. Approach: Field Programmable Gate Array (FPGA) provides reconfiguration and implementation at the same time. Results: The implementation … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 6,701 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign and Field Programmable Gate Array Implementation of Basic Building Blocks for Power-Efficient Baugh-Wooley MultipliersMuhammad H. Rais, Bandar M. Al-Harthi, Saad I. Al-Askar, Fahad K. Al-HusseinProblem statement: As growing demands on portable computing and communication systems, the power-efficient multipliers play an important role. In these multipliers basic multiplication follows the Baugh-Wooley algorithms and can easily be implemented using Field Programmable Gate Array (FPGA) devices because the development cost for Application Specific Integrated Circuits (ASICs) are high. These algorithms should be verified and optimized before implementation. … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,129 accessesView PDFCite
