Research ArticleOpen accessEvery word in the titleA Prescriptive Specialized Learning Management System for Academic Feedback towards Improved LearningAnnette van der Merwe, Tiny du Toit, Hennie KrugerThe dynamic nature of technological advances is causing changes in many fields and especially in tertiary education. Student numbers are increasing annually and institutions need to maintain education quality whilst ensuring student retention. A specialized learning management system (SLMS) was developed in this study that provides students with comprehensive feedback which will enable them to better manage their academic performance. … …Journal of Computer Science, Vol. 14, Issue 10 · 24 Oct 2018 · 7,480 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFeedback Control of Quad-Rotors with a Matlab-Based SimulatorStephen Armah, Sun Yi, Wonchang Choi, Dongchul ShinPrecise regulation of position and attitude (roll, pitch and yaw) is one of the most critical tasks to be considered in designing controllers for quadrotor types of Unmanned Aerial Vehicles (UAVs). The MATLAB-based simulator for quadrotors using PD-feedback control to achieve stabilization was developed. MATLAB/Simulink models are used to design and validate the control algorithms and the simulation results are … …American Journal of Applied Sciences, Vol. 13, Issue 6 · 23 Jun 2016 · 7,865 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRemediation of Feedlot Nutrients Runoff by Electrocoagulation ProcessArjun Thapa, Shafiqur Rahman, Md. Saidul BorhanNutrient runoff from Concentrated Animal Feeding Operations (CAFOs) may cause ground and surface water pollution. Scientists and researchers are continually searching for appropriate technologies to mitigate feedlot nutrient runoff pollution. In this study, suitability of electrocoagulation treatment process was examined under laboratory conditions to mitigate nutrient pollutants from the feedlot runoff. Feedlot runoff was treated with three different type of … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 9 Nov 2015 · 7,080 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleResource Selection in Grid Environment Based on Trust Evaluation Using Feedback and PerformancePrakash Mohan, Ravichandran ThangavelA grid computing is a collection of distributed computing resources owned by many organizations across boundaries and not dedicated for a single user available in the Virtual Organization. Grid computing environment provides more computational capabilities to increase the scalability and efficiency of the infra-structure. Resource selection in computational grid is the open issue for executing complex jobs. Trust is the … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 7,169 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRobust Positioning of Laser Beams Using Proportional Integral Derivative and Based Observer-Feedback ControlKwabena A. Konadu, Sun Yi, Wonchang Choi, Taher Abu-LebdehHigh-precision positioning of laser beams has been a great challenge in industry due to inevitable existence of noise and disturbance. The work presented in this study addresses this problem by employing two different control strategies: Proportional Integral Derivative (PID) control and state feedback control with an observer. The control strategies are intended to stabilize the position of a laser beam … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 19 Apr 2013 · 6,868 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluence of Microbial Inoculants on Feeding Value of Spent Lentinula edodes SubstrateYunfu Gu, Min Yi, Jianzhou Chen, Xiaoping ZhangSawdust-based Spent Lentinula Edodes Substrate (SLES) is an important agricultural waste resource for its’ huge production amount, on the other hand, it is hard to recycling because of the low digestibility. For the purpose of recycling the SLES, a study was conducted to improve the feeding values of SLES via microbial inoculation. The SLES was ensiled with 0.5% (v/w) Lactic … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 20 Sep 2012 · 7,911 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLow Transition-Generalized Linear Feedback Shift Register Based Test Pattern Generator Architecture for Built-in-Self-TestP. Sakthivel, A. Nirmal KumarProblem statement: In Built-In Self-Test (BIST), test patterns are generated and applied to the Circuit-Under-Test (CUT) by on-chip hardware; minimizing hardware overhead is a major concern of BIST implementation. In pseudorandom BIST architectures, the test patterns are generated in random nature by Linear Feedback Shift Registers. This normally requires more number of test patterns for testing the architectures which need … …Journal of Computer Science, Vol. 8, Issue 6 · 13 Mar 2012 · 7,765 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStatistical Analysis and Learning Method on Users' FeedbacksDoris Hooi-Ten Wong, Sureswaran RamadassProblem statement: The purpose of this study was constructing an effective algorithm in order to learn the users’ feedbacks from their displayed visualization. This is due to existing visualization tools typically involve presenting network data regardless of considering level of network data knowledge among different levels of computer users. The machine learning algorithm has been applied in order to find … …Journal of Computer Science, Vol. 7, Issue 9 · 26 Jul 2011 · 6,525 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Laboratory Study of Curiosity Behavior in Feedback-Based DecisionsTakemi FujikawaProblem statement: This study adopts an interdisciplinary approach in conducting the study on "curiosity" with a toolset of experimental economics. Approach: I hypothesized that the Decision Makers (DMs) tended to exhibit curiosity behavior when two conditions were met: (1) The DMs faced "small feedback-based" decision problems; (2) The DMs bore tangible costs of their curiosity behavior. Results: This study was … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 7,461 accessesView PDFCite
