The Haralick statistical features based feature extraction along with Bayes classifier to classify the Osteoarthritis (OA) knee x-ray images is proposed. During feature extraction the Haralick features are extracted from the gray level co-occurrence matrix of the knee x-ray image at predefined angle with an offset of one pixel. In the classification module, the extracted features are fed into a Bayes classifier. Totally, 130 knee x-ray images are used for performance analysis. Initially, the performance of the proposed approach is analyzed by using the Haralick features extracted along a particular angle by using Bayes classifier. In order to improve the classification accuracy, fusion of Haralick features and also a hybrid approach by combining the type of smoother is used. The experimental results obtained are satisfactory.

A Mobile Ad Hoc Network (MANET) is usually assumed to be homogeneous, where each mobile node shares the same radio capacity. However, a homogeneous ad hoc network suffers from poor scalability. Building a physically hierarchical ad hoc network is a promising way to achieve good scalability. Routing is critical to operate such a hierarchical structure efficiently. Most routing protocols in MANETs are designed for a homogeneous wireless network. It has been proven that current routing protocols work well in small size networks. However, the large-scale ad hoc networks are more and more desired in many application scenarios, especially the mobile military networks. In this paper, we propose a novel self-organizing hierarchical architecture for improving the scalability properties of ad-hoc wireless networks. This paper focuses on the design and evaluation of routing protocol applicable to this class of hierarchical ad-hoc networks. The performance of modified Dynamic Source Routing (DSR) protocol in a two level hierarchical network is evaluated and compared with that of conventional DSR in a flat ad-hoc networks using NS-2 simulator. Simulation results using NS-2 show that our proposed schemes achieve good performance.

The main purpose of corporations is maximizing shareholders wealth. one of the factors which Affect it, is the company\'s dividend policy; therefore, discussion of dividend policy has always Been considered as one of the most important financial issues. this study investigates the impact Of ownership structure and stock price volatility on pay out ratio in listed Firms of Tehran Stock Exchange. in this context, multiple linear regression was used. the findings of studying 113 Companies during the time period between 2006 and 2011showed that Institutional ownership and Stock price volatility affect the ratio of dividends of firms accepted in Tehran Stock Exchange Positively . however, there are some reasons which show there is not meaningful relationship Between management ownership and corporate ownership with dividend policy.

The present paper studies effect of maximal exercise and submaximal exercise on treating type 2 DM (diabetes mellitus). In type 2 DM, pancreas does not produce enough insulin or body cells do not respond to the produced insulin. As a result, level of blood sugar increases. Approximately, 90 percent of diabetes are related to type 2 DM. In this research, statistical population is made up of 10 male volunteers whose mean age varies from 24 to 69, height is equal to 171.7∓ 6.12 centimeters, weight is equal to 81.52 ∓ 1.59 kilograms, and body mass index( BMI) is equal to 27.65 ∓ 1.88 . The volunteers participated in two sessions of aerobic exercise including 30 minutes of fast running, one session with speed equal to 70 percent of heart beat and another session with speed equal to 100 percent of heart beat. Data analysis was done based on descriptive and inferential methods. Moreover, statistical measures such as measure of central tendency, measure of dispersion were used to study findings and paired T test and Mann Whitney U- test were used to compare relation between data dependent variables in constant and non- constant groups at confidence level equal to 95 percent. Results of paired T test shows that doing maximal and submaximal exercises affects BMI and percent of glycosylated hemoglobin.

Mathematics is one of the most important issues around the world. Being skillful in mathematical facts, researchers can access scientific and professional facilities. In present paper, the multiplication learning process in children would be investigated, but it doesn’t go further in this matter. Just the normal procedure of learning mathematics has been investigated here and not learning math in children with some difficulties. Thus, it has been attempted to study how children gain proficiency in mathematics. In the process of becoming proficient, children need to use some strategies to solve mathematical problems; however, these strategies need to change in some time with the help of practice. The change of strategies are useful because it helps the strategies go towards more automaticity in solving the arithmetic problems and as a result of this it frees up more space in the working memory for more complicated cognitive processes.

The purpose of this study is to investigate the mother and father parenting style of the demographic data in the faculty of education, university Technology Malaysia, among 300 undergraduate students in the faculty of education who involved in the study. These types of parenting style includes authoritarian, authoritative, and permissive, were assessed by using Parent Authority Questioner (PAQ). Several issues were associated such as the relationship of parenting style of the mother and the father with their income and their level of education. Analysis of variable (ANOVA) shows that there is no significant difference between the parenting style and the level of education and level of income for both, the mother and father. Further analysis shows that the lower level of income mother and father are more likely to practiced authoritarian parenting style to the children. The same indication also appears for the mother and father of lower level of education. Several suggestions are also presented.

The purpose of this effort is to conduct a combined Eulerian-Lagrangian non-linear dynamics computational analysis of the interaction between a single planar blast wave and a human head in order to assess the extent of intra-cranial shock wave generation and its potential for causing traumatic brain injury. The finite element (FE) modeling is a powerful tool for investigating the physical process producing head trauma, and a well validated model would, thus, be a valuable tool to aid in injury diagnosis and design of protective devices. In this paper, an Ansys three dimensional transient modal dynamic finite element analysis was performed of a simplified brain model surrounded by cerebral spinal fluid and skull. Viscoelastic material parameters of the brain tissue were obtained from open literature. The localized response parameters predicted by the head model will be analyzed and compared between various loading conditions.

Abstract\nIntroduction: CRM consists of three main parts: Customer, Relationship and Management. Among the three mentioned factors, the “Relationship” process forms the focal sector. According to the hypothesis of this study, “customer’s organizational visiting” has a significant role on their satisfaction.\nThe objective of this study was to investigate the impact of “customer’s organizational visiting” on Consumer/ Provider Attachment (CPA) in the framework of Customer Relationship Management (CRM) system.\nMethods: The study is a survey research that uses correlation method by two researcher made questionnaires that included 46 questions. Experts confirmed the validity and reliability of the questionnaires was calculated by Cronbach\'s alpha. All of telecommunications experts who are using the products were among Population. The sample size was 350 subjects that were randomly selected. Both descriptive and inferential statistics methods have been used to analyze data.\nResults and conclusion: The results of the hypothesis testing show that null hypothesis rejected and the alternative-hypothesis accepted. The results show that “customer’s organizational visiting” increases their satisfaction. Regardless of its administrative details “customer’s organizational visiting” can be considered among the most powerful Customer Relationship Management (CRM) tools which tend to Consumer/Provider Attachment (CPA). \nKeywords: organizational visiting, Consumer/ Provider Attachment (CPA), CRM.
