Research ArticleOpen accessIn the abstractStressors Influence on Salmonella enterica Serovar Enteritidis Colonization in BroilersE. S. Soliman, E. Taha, K. D. Infante et al.Problem statement: Poultry industry usually exposing birds to a variety of actions and stressors includs fasting for gastrointestinal emptying before transportation and where birds are often exposed to high environmental temperature during the summer months. These environmental stressors may have influences on bird performance and susceptibility to pathogens such as Salmonella enteritidis by altering the intestinal micrbiota and changes in … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 3 · 12 Sep 2009 · 7,190 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Method for Accuracy Assessment of Sub-Pixel Classification ResultsH. Emami, B. MojaradiProblem statement: Classification accuracy assessment is the main stage of information extraction to evaluate the performance of a classifier. According to the output's classifiers (thematic map/fraction map), a properly strategy for accuracy assessment should be taken into consideration. Since pure pixels are used in traditional accuracy assessment of full pixel classifiers they are not suitable for assessment of sub-pixel classifiers. … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,482 accessesView PDFCite
Research ArticleOpen accessIn the abstractIndoor Characterisation using High-Resolution Signal Processing Based on Five-Port Techniques for Signal Input Multiple Output SystemsSmari Mouheddin, Bel hadj Taher JamelProblem statement: The development of wideband mobile communication systems requires a deep knowledge of the characteristics of the indoor mobile radio channel. The characterization of the indoor multi-path propagation structure is important in developing antifading techniques for high-speed digital radio access. The high-resolution of the estimation of the Time of Arrival (ToA) and the Direction of Arrival (DoA) of multi-path … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,689 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Physiological Effects on Hormones levels and Kidneys Functions Induced by The Anabolic Androgenic Drug (Sustanon) in Male Guinea PigsAmeen Saleh Ahmed Bin BisherProblem statement: In recent years, the intentional abuse of anabolic androgenic drugs by athletes has increased rapidly in many countries to become a serious negative phenomenon. Athletes, specially in power sports, abuse these drugs such as Sustanon in high doses to obtain a rapid and huge increasing in the muscles mass and to improve their performance during the sport competitions. … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,028 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Application of Combined Model for Tehran Metropolitan Area Incorporating Captive Travel BehaviorShahriar A. Zargari, Morteza Araghi, Kouros MohammadianTo overcome deficiencies of the sequential transportation planning approach, this research applies a Combined Trip Distribution and Assignment Model (CTDAM) for the simultaneous prediction. The proposed combined model can itself be reformulated as an Equivalent Minimization Problem (EMP). When applying the Evans algorithm to the EMP, the CTDAM is expected to be usable in a realistic application. The objective of … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,857 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Changes of Some Electrolytes after Two Months ActivityM. J. Pourvaghar, A. R. ShahsavarSome investigators have speculated that sodium chloride losses in sweat associated with net dehydration may lead to the observed hyponatremia after prolong strenuous exercise. The effects of altered hydration can influence athletes cognitively in addition to physically. In this research, rest alterations of sodium and potassium of blood serum have been investigated. The subjects were male students who have been … …Journal of Social Sciences, Vol. 4, Issue 4 · 31 Dec 2008 · 7,937 accessesView PDFCite
Research ArticleOpen accessIn the abstractNonlinear Behavior of Single Piles in Jacket Type Offshore Platforms Using Incremental Dynamic AnalysisMohammad Amin Assareh, Behrouz AsgarianThe operation for offshore oil has become an important issue in the recent years. Offshore platforms are some of those structures which are built to withstand environmental and accidental loads during oil exploitation operation. One of the most usual types of these platforms is the Jacket Type Offshore Platform (JTOP) which can be divided into three important parts, which are … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 9,305 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmbedding Malaysian House Red Ant Behavior into an Ant Colony SystemZ. A. Othman, H. M. Rais, A. R. HamdanProblem statement: Ant Colony System (ACS) is the most popular algorithm used to find a shortest path solution in Traveling Salesman Problem (TSP). Several ACS versions have been proposed which aim to achieve an optimum solution by adjusting pheromone levels. However, it still has a room on an improvement. This research aims to improve the algorithm by embedding individual Malaysian … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,962 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeed Estimation of Adaptive Fuzzy-Controlled Piezo-Electric Motor using MLP-Neural NetworkShebel ALSABBAH, Tariq MUGHRABIThe speed of ultrasonic motor of piezo-electric type is usually measured using mechanical sensors such as pulse encoders. However, these sensors are costly and bulky. In this paper, a numerical speed estimation approach of a piezo-electric motor (PEM) is implemented using multilayer perception neural network (MLP-NN). The proposed model evaluates rotational speed and load torque based on the amplitude and … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 6,790 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing a Simulation Tool to Model the Ground Level Concentrations of Green House Gases Emitted by Flaring in Petroleum Production in Kuwait OilfieldsKhaireyah Kh. AL-Hamad, V. Nassehi, A.R. KhanAir pollution and its effects on the ecosystem has been a source of concern for many environmental pollution organizations in the world. In particular climatologists who are not directly involved in petroleum industry sometimes express concerns about the environmental impacts of gas emissions from flaring at well heads. For environmental and resource conservation reasons, flaring should always be minimized as … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 6,670 accessesView PDFCite
