A Framework for Intelligent Decision Support System for Traffic Congestion Management System  [PDF]
Mohamad K. Hasan
Engineering (ENG) , 2010, DOI: 10.4236/eng.2010.24037
Abstract: Traffic congestion problem is one of the major problems that face many transportation decision makers for urban areas. The problem has many impacts on social, economical and development aspects of urban areas. Hence the solution to this problem is not straight forward. It requires a lot of effort, expertise, time and cost that sometime are not available. Most of the existing transportation planning software, specially the most advanced ones, requires personnel with lots practical transportation planning experience and with high level of education and training. In this paper we propose a comprehensive framework for an Intelligent Decision Support System (IDSS) for Traffic Congestion Management System that utilizes a state of the art transportation network equilibrium modeling and providing an easy to use GIS-based interaction environment. The developed IDSS reduces the dependability on the expertise and level of education of the transportation planners, transportation engineers, or any transportation decision makers.

Price and Income Elasticities of Gasoline Demand in Iran: Using Static, ECM, and Dynamic Models in Short, Intermediate, and Long Run  [PDF]
Vahid Mohamad Taghvaee, Parviz Hajiani
Modern Economy (ME) , 2014, DOI: 10.4236/me.2014.59087
Abstract:

Price and income elasticities of gasoline demand show whether the price policy, pursued by the Iranian government, can decrease the high gasoline consumption sufficiently or not. Since the two oil price shocks in 1970 and 1973, interest in the study of oil products demand has increased considerably, especially on gasoline. High gasoline consumption is a serious crisis in Iran, posing economically, politically, and environmentally threats. In this study, the elasticities are estimated over three intervals, short run, intermediate run, and long run in Iran during 1976-2010, by putting the estimates of Error Correction Model (ECM), static model, and dynamic model in an increasing order, respectively. The short run, intermediate run, and long run price elasticities are -0.1538, -0.1618, and -0.3612 and the corresponding income elasticities are 0.2273 - 0.3581, 0.4636, and 0.7284, respectively. Not only do these elasticities imply that the gasoline demand is price and income inelastic but also the adjustment velocity, estimated by ECM, is a low point at -0.1942. Based on the estimations, the gasoline demand responds to the changes of price and income slightly and slowly. Therefore, policy makers should develop more strategies to reduce gasoline consumption, for example, substitute goods, public transportation systems, and environmental standards settings.

Study the Specifications of the Thread through the Construction of the Pipe on the Ring Spinning Machine  [PDF]
Mohamad Yaser Joha, Easa Morad
Journal of Biomedical Science and Engineering (JBiSE) , 2015, DOI: 10.4236/jbise.2015.84028
Abstract: In ring spinning, tension develops in the yarn mainly because, to move the Traveler and the balloon length, Lb, around the spindle axis, and to wind the yarn onto the spinning bobbin, work must be done against the frictional force of the ring on the Traveler and of the Traveler on the yarn, as well as against the air drag on the Traveler and on the balloon length. This work is additional to that needed to overcome the friction of the spindle bearings and the air drag on the forming yarn package. The tensions in the yarn during ring spinning may be considered with respect to three zones: 1) the yarn formation zone (i.e., the zone between the pigtail lappet guide and the front rollers of the drafting system); 2) the winding zone (i.e., the zone between the Traveler and the bobbin forming zone); 3) the balloon zone (i.e., the zone between the Traveler and lappet guide), where the yarn tension changes noticeable shape by relation with Winding Qatar (the yarn tension increases whenever Winding Qatar reduces).
Calibration of a Rainfall-Runoff Model to Estimate Monthly Stream Flow in an Ungauged Catchment  [PDF]
Shahrbanou Firouzi, Mohamad B. Sharifi
Computational Water, Energy, and Environmental Engineering (CWEEE) , 2015, DOI: 10.4236/cweee.2015.44006
Abstract: Simulation of runoff in ungauged catchments has always been a challenging issue, receiving significant attention more importantly in practical applications. This study aims at calibration of an Artificial Neural Network (ANN) model which is capable to apply in an ungauged basin. The methodology is applied to two sub-catchments located in the Northern East of Iran. To examine the effect of physical characteristics of the catchment on the capability of the model generalization, it is attempted to synthesize effective parameters using empirical methods of runoff estimation. Firstly, the model was designed for a pilot sub-catchment and the statistical comparison between simulated runoff, and target depicted the capability of ANN to accurately estimate runoff over a catchment. Then, the calibrated model was generalized to another sub-catchment assumed as an ungauged basin while there are runoff data to compare the result. The result showed that the designed model is relatively capable to estimate monthly runoff for a homogenous ungauged catchment. The method presented in this study in addition to adding effective spatial parameters in simulation runoff and calibration of model by using empirical methods and the integration of any useful accessible data, examines the adaptability of model to an ungauged catchment.

Norshidah Mohamad Salleh, Khalim Zainal
Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.914172
Abstract: This paper discusses a proposed instruction model for intervention of social skills children with visual impairment. Intervention model based on Badura’s Social Cognitive Learning Theory were?proposed to help students with visual impairment in the development of their social skills. The emphasis of the theory was based on imitation, environment and cognition. The three elements are interrelated in the development of social skills and individual behavior. The theory stressed the process of learning behavior through imitation. Without visual information, the imitation was learnt from the information through hearing and touch as well as physical model. The process of imitation was received with reward, reinforcement and motivation will strengthen the social skills learned and the target behavior. In addition, teachers, parents and the communities have an important role in helping and training the visually impaired children to improve their social skills. The impact of the proposed intervention model, the social skill of visual impairment children?will be improved so that they can?be?socialized effectively with typical children.

Some Properties of Fuzzy Quasimetric Spaces

International Journal of Mathematics and Mathematical Sciences , 2010, DOI: 10.1155/2010/514747
Abstract: Some properties of fuzzy quasimetric spaces are studied. We prove that the topology induced by any -complete fuzzy-quasi-space is a -complete quasimetric space. We also prove Baire's theorem, uniform limit theorem, and second countability result for fuzzy quasi-metric spaces. 1. Introduction and Preliminaries Zadeh [1] introduced the concept of fuzzy sets as a new way to represent vagueness in our everyday life. Since then, many authors regarding the theory of fuzzy sets and its applications have developed a lot of literatures. Fuzzy Metric Spaces and existence of fixed points in fuzzy metric spaces have been emerged as two of the major of research activities. As natural, several mathematicians have introduced fuzzy metric spaces in different ways (Kramosil and Michálek [2], Erceg [3], Deng [4], Kaleva and Seikkla [5]). The definition proposed by Kramosil and Michalek in 1975 [2] is the most accepted one which is closely related to a class of probabilistic metric spaces [6]. Following this definition, a lot of research have been done on the existence of fixed points for the mappings under different conditions. Many authors have investigated and modified the definition of this concept and defined a Hausdorff topology on this fuzzy metric space. They showed that every metric induces a fuzzy metric, and, conversely, every fuzzy metric space generates a metrizable topology [2, 7–9]. Recently, many authors observed that various topological properties, fixed point theorems, and contraction mappings in metric spaces may be exactly translated into fuzzy metric spaces [10–21]. On the other hand, Künzi in [22] showed that the concepts from the theory of quasimetric spaces can be used as an efficient tool to solve several problems from theoretical computer science, approximation theory, topological algebra, and so forth. In [23], Gregori and Romaguera introduced and studied the class of fuzzy quasimetric spaces as a natural generalization of the corresponding notion of fuzzy metric space to the quasimetric. Our paper continues to study such spaces and investigates some properties of this class. In particular, we address issues related to compactness, completeness, and Baire's theorem. A binary operation is a continuous -norm [6] if satisfies the following conditions: (1) is associative and commutative.(2) is continuous.(3) for every (4) whenever and with Example 1.1. The four basic -norms are the following. (1)The Lukasierviez -norm: .(2)The product -norm: (3)The minimum -norm: (4)The weakest -norm, the drastic product: Using pointwise ordering, we have the

Abstract: Amin M (2010) Intervention of genetic flow of the foreign cattle toward diversity of phenotype expressions of local cattle in the District of Banyuwangi. Biodiversitas 10: 69-74. The aims of the present research are two folds: to know the phenotypic diversity and to reconstruct the cross-breeding pattern of local cattle in Banyuwangi. Based on three sampling areas, it was found that there were 32 phenotypic cattle (10 in the sub districts of Rogojampi, 16 in Tegaldlimo and 6 in Glagah areas). The phenotypic varieties were caused by two factors, namely the flow of genetic intervention of the other local cattle (Bali, Ongole, and Brahman cattle) and the artificial insemination program using the semen of Limousine, Simmental, Aberdeen Angus and Santa Gertrudis cattle.
