The Mixed Least Squares Meshfree (MDLSM) method has shown its appropriate efficiency for solving Partial Differential Equations (PDEs) governing the engineering problems. The method is based on the minimizing the residual functional. The residual functional is defined as a summation of the weighted residuals on the governing PDEs and the boundaries. The Moving Least Squares (MLS) is usually applied in the MDLSM method for constructing the shape functions. Although the required consistency and compatibility for the approximation function is satisfied by the MLS, the method loss its appropriate efficiency when the nodal points cluster too much. In the current study, the mentioned drawback is overcome using the novel approximation function called Mapped Moving Least Squares (MMLS). In this approach, the cluster of closed nodal points maps to standard nodal distribution. Then the approximation function and its derivatives compute noting the some consideration. The efficiency of suggested MMLS for overcoming the drawback of MLS is evaluated by approximating the mathematical function. The obtained results show the ability of suggested MMLS method to solve the drawback. The suggested approximation function is applied in MDLSM method, and used for solving the Burgers equations. Obtained results approve the efficiency of suggested method.

Urban Squares constantly were known as one of the effective urban spaces in ancient cities and also in Iran in which all types of citizen’s presence are observed in them. But, recently, due to entering cars in cities, they have missed previous meaning and have been transformed to traffic elements which are suppressed by vehicles. This issue causes ignorance of aesthetics elements in modern Squares. Indeed, what is known as new urban square definitions has far distance by previous definition. With respect to this introduction, this paper aims to study influential factors of aesthetics in urban Squares. Therefore, 3 Squares of Hamadan which have significant differences by the measures of physical, cultural and social characteristics were selected. Research method is descriptive-analytic and spss software has been applied to perform ANOVA test. Results showed that predesign and socio-cultural factors significantly influence aesthetical citizen’s persecution of Squares.

The current research was conducted with the aim of determining the effectiveness of training courses held for teachers based on the Kirkpatrick model. The research population is all the people who participated in the mentioned training courses and finally, 123 people who participated in the courses during 2013-2014 were selected as a sample through simple random sampling method. This research is descriptive in terms of data collection, practical in terms of purpose, and evaluation in terms of function. To collect information in the first level, the reaction level evaluation form was used, and in the second and third levels, a questionnaire was used to evaluate learning and behavior. One-sample t-test was used to analyze the obtained data. The findings of the research indicated that there was no optimal effectiveness in all four levels of reaction, learning, behavior and results, and the main reasons for this were the failure to conduct a needs assessment for the mentioned courses, and the lack of mastery of the professors of the courses. The content and method of teaching, lack of attention and correct criteria to attract the professors of the courses, lack of motivation in the teachers to participate effectively in the courses and attend only to receive certificates and degrees, and lack of attention to useful and practical content in the courses.

Objective: People who have higher social health can more successfully deal with the challenges and ups and downs of playing key social roles and participate more in collective activities and prevent social deviations and anomalies. In this regard, foresight and the development of a forward-looking strategy model by the media can play an important role in promoting the social health of their audience (individuals).Method: This research has been done qualitatively and quantitatively. In the qualitative phase, content analysis and Q methods were used, and in the quantitative phase, factor analysis was used to analyze the Q method data.Results: The content analysis of the media in this study showed that the most media production in the field of social deviations with 576 cases and the lowest media production in the field of violence with 237 cases. The field of social quality with 485 and the field of social issues with 312 cases are in the second and third ranks. A small questionnaire was made and based on it, the desired model was designed using PLS software. Conclusion: This model showed that the function of media is effective in promoting social health of society and can have the greatest impact on improving quality of life, reducing violence, reducing social deviations and social issues.

Urban Squares of Iran have undergone various structural changes from tradition to modernity. These changes have influenced socio-cultural life of urbanites in various dimentions. It is vital to identify the structural features of urban Squares in order to manage and implement constructive solutions. The present research investigates the structural changes of urban areas. In order to accomplish this goal, four Squares of Tehran, namely Imam Khomeini, Baharestan, Inghelab, and Azadi Squares are selected as samples for case study. The research methodology is historical-analytic, and documents and field observations were the two data collection methods used. In the course of work, structural features and indexes of the square were extracted from different sources and described and analyzed in the four targeted Squares. The results show differences in structure between Imam Khomeini and Baharestan Squares, which were built during Ghajar dynasty, on the one hand, and that of Inghelab and Azadi Squares, which were built during Pahlavi 1st and 2nd reigns respectively. The Squares of Ghajar period have an amalgamation of traditional and modern elements within and in the body of the square. But the Squares of Pahlavi period are far away from the structural features of traditional Squares and are turned into modern Squares. This trend has continued during the Islamic Republic.

The view of today cities due to technology improvements and discontrolling of comsuming ideas changes to a cold, rigid and lifeless building. This process makes the citizens became faraway from nature and brings some mental disorders. Urban art with making happy and cozy places can reduce this tension to some extent. Tehran as a symbol of political and cultural authority in this country, is noticed by any Iranian and tourisms. This article is aimed to by analysis some elected statues in Tehran, will gain abilities and losses of urban art in capital. This article has been written using the research, historical and descriptive investigation methods and the library sources have been used to aggregate information. The square element is one of the most city public spaces. It prepares a place to establish a statue among the other places. The role of statues will increase through Squares so they with their special structures can identify the city and the places where they are established. By considering this fact this letter is trying to choose some urban spaces and analysis them in order to investigating the way of making urban sculptures in Iran through recent deceads.

In this paper, we propose a nonparametric rank-based alternative to the least-Squares independent component analysis algorithm developed. The basic idea is to estimate the squared-loss mutual information, which used as the objective function of the algorithm, based on its copula density version. Therefore, no marginal densities have to be estimated. We provide empirical evaluation of the proposed algorithm through simulation and real data analysis. Since the proposed algorithm uses rank values rather than the actual values of the observations, it is extremely robust to the outliers and suffers less from the presence of noise than the other algorithms.

Determination of the diffusion coefficient on the base of solution of a linear inverse problem of the parameter estimation using the Least-square method is presented in this research. For this propose a set of temperature measurements at a single sensor location inside the heat conducting body was considered. The corresponding direct problem was then solved by the application of the heat fundamental solution.
