Research ArticleOpen accessIn the abstractLiDAR-Based Obstacle Detection and Avoidance for Navigation and Control of an Unmanned Ground Robot Using Model Predictive ControlSai Charan Dekkata, Sun Yi, M. A. Muktadir, Selorm GarfoUnmanned Ground Vehicles (UGVs) have, as of late, been utilized in a wide assortment of utilizations because of their flexibility, diminished expense, and quick response, among other benefits. Search and Rescue (SAR) is quite possibly the most conspicuous zones for the work of UGVs instead of a monitored mission, mainly due to its impediments on the expenses, human resources, and … …Journal of Mechatronics and Robotics, Vol. 7, Issue 1 · 30 Mar 2023 · 8,219 accessesView PDFCite
Research ArticleOpen accessIn the abstractSuperovulation Response and Embryo Quality Recovered Following Flushing Nguni Heifers and CowsAyanda Maqhashu, Masindi L. Mphaphathi, Pokgedi J Sebei et al.The aims of the study were to compare super ovulatory response, fertilization rate and evaluate embryo quality recovered from super ovulated Nguni stud cows and heifers. Nguni cows (n = 15) and heifers (n = 10) aged 4-6 and 2 years, respectively, were used as embryo donors. Embryo donors were synchronized for estrus before superovulation. For superovulation donors were administered … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 4 · 25 Nov 2021 · 6,433 accessesView PDFCite
Research ArticleOpen accessIn the abstractStandardized Ileal Digestible Lysine Requirement of 6- to 10-kg Weanling PigsChan Sol Park, Beob Gyun KimThe objective of the experiment was to determine the Standardized Ileal Digestible (SID) lysine requirement for weanling pigs from 6 to 10 kg of Body Weight (BW). A total of 216 weanling pigs with an initial BW of 6.23±0.93 kg were assigned to six diets in a randomized complete block design with five blocks based on BW. Six corn-dried whey-soybean … …American Journal of Animal and Veterinary Sciences, Vol. 10, Issue 3 · 10 Jun 2015 · 7,548 accessesView PDFCite
Research ArticleOpen accessIn the abstractController Based Observer in Switched System with Norm Bounded UncertaintyMongi Besbes, Elyes MaherziProblem statement: This study discusses the robust stabilization of norm bounded discrete switched systems. Approach: The proposed method is using the second Lyapunov approach and the poly-quadratic function concept. The stabilization conditions are written through linear matrix inequality relations. The control law is based on a static output feedback with the use of a switched observer. The synthesis conditions of … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 11 May 2012 · 6,908 accessesView PDFCite
Research ArticleOpen accessIn the abstractAboveground Biomass Production of Rhizophora apiculata Blume in Sarawak Mangrove ForestI.A. Chandra, G. Seca, M.K. Abu HenaProblem statement: Mangrove forests are found in tropical and subtropical coastal tidal regions. Rhizophora apiculata Blume is one of the most important species in mangrove forest. It is also one of the commercial mangrove timber species in Asia-Pacific region which dominates large areas of mangrove in this region. In order to understand forest ecosystem characteristics and to establish the proper … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 21 Oct 2011 · 10,610 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Separable Logarithmic Algorithm for Non-Linear OptimizationAbbas Y. Al-Bayati, Hawraz N. JabbarProblem statement: The idea of this study stemmed from the fact that most of the currently used optimization algorithms use a local quadratic representation of the objective function. It also arisen from the fact that the objective function may not be represented adequately by quadratic functions and the global minimizer may be obtained for objective functions. So, in this study, … …Journal of Computer Science, Vol. 6, Issue 5 · 31 May 2010 · 6,874 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 abstractStatistical Models for Hardened Properties of Self-Compacting ConcreteArabi N.S. Al Qadi, Kamal Nasharuddin Bin Mustapha, Hashem Al-Mattarneh, Qahir N.S. AL-KadiProblem statement: For predicting workability and hardened properties of Self-Compacting Concrete (SCC) no well known explicit formulation. Approach: Statistical models were carried out to model the influence of key mixture parameter (cement, water to powder ratio, fly ash and super plasticizer) on hardened properties affecting the performance of SCC. Such responses included compressive strength at 3, 7 and 28 days … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 8,148 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectronic Energies in Delta Doped AlGaAs/GaAs HeterostucturesA. Meftah, H. Ajlani, A. Marzouki et al.The band bending of the potential at the AlGaAs/GaAs interface increases with the electrons concentration in the GaAs channel. This band bending is often ignored in the theoretical calculation of the electronic energies and a linear potential approximation was used. This led to imprecise energy values and occupied subband configurations. We have taken account of the band bending in the … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 6,932 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimizing Nano-silver Formation by Fusarium oxysporum PTCC 5115 Employing Response Surface MethodologyM. Karbasian, S. M. Atyabi, S. D. Siadat et al.Fusarium oxysporum was grown in medium containing malt, yeast extracts and glucose on shaker at 25±1°C and180 rpm for 96 h. The mycelia were used to convert silver nitrate solution into nano-silver. The bioconversion was optimized through response surface methodology-central composite design .The factors which affected the process were pH, temperature, agitation rate, concentration of silver nitrate, time of reaction … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,631 accessesView PDFCite
