The growth and development of urban settlement have always been accompanied by industrial activities. Previous experience shows that after industrialization of the countries and the local selection of their industries in big cities, these cities have faced with enormous work force immigration and have observed severe changes in their urban system. These changes are mostly caused by the execution of the growth pole policy and the concentrated distribution of industries in these countries’ centers.\nIn Iran, after the solar 1340s (1961-1971C.E.), we have observed severe changes in urban system that its coincidence with the country’s industrialization requires lots of considerations. The execution of the industries’ establishment prohibition in a distance of 120 kilometers from Tehran is the appearance of one of the presented means in this era. But we still witness the big industries’ presence by 90% in Tehran in 1981. This paper is to proceed with the method of industries’ distribution in Iran by analyzing the place of small and big industries separately in cities with a population of more than 100.000 members. In line with this, using the addresses of the active workshop places registered in Industries Organization, the number of existing industrial workshops in cities with a population of more than 100.000 members in the country are categorized in the basic table in their population order; then, for scoring the importance and effectiveness of each industry, the number of individuals working in the workshop variable was used to determine the workshop’s importance factor.\nThe results of the analysis express that 55% of the 28663 active workshops registered in cities with a population of more than 100.000 members are selected their local in only 7 cities namely Tabriz, Mashhad, yazd, Isfahan, Qom, Tehran, and Karaj, which shows a kind of disproportion in the industries’ distribution across the country. Also, more than 90% of the existing active industrial workshops in cities with a population of more than 100.000 members have been in the range of less than 50 employed industries that included 50% of the employed members in the industry sector.
The results from the parametric study reveal that the most important design features for energy saving are demand-controlled ventilation as well as limited glazing on the facade. Further energy-saving features are efficient lighting and office equipment which strongly reduce user-related electricity and cooling energy. Together, the simulation results suggest that about 48% energy can be saved compared to a new office building built accordingto the Swedish building code. Thus, it is possible, using a combination of simple and well-known building technologies and configurations, to have very low energy use in new office buildings. If renewable energy sources, such as solar energy and wind power, are added, there is a potential for the annual energy production to exceed the annual energy consumption and a net zero-energy building can be reached. One aspect of the results concerns user-related electricity, which becomes a major energy post in very low-energy offices and which is rarely regulated in building codes today. This results not only in high electricity use, but also in large internal heat gains and unnecessary high cooling loads given the high latitude and cold climate.
Total quality management (TQM) is considered a very important factor for the long-term success of an organization. TQM implementation has been an important aspect for improving organisational efficiency. The links between TQM and performance have been investigated by numerous scholars. While examining the relationship between TQM and performance scholars have used different performance types such as financial, innovative, operational and quality performance. Recent research on total quality management has examined the relationships between the Total quality management and organizational performance. TQM focuses on continuous process improvement within organizations to provide superior customer value and meet customer needs. TQM a popular guideline for organizational management is adopted for developing strategic infomaps and infocharts for an information organization
The classification of Acute Coronary Syndrome (ACS) using artificial intelligence (AI) decision making systems has gained plenty of attention during recent years. Using this approach, we can differentiate patients with myocardial infarction (MI) from those with unstable angina (UA). The present study aims to develop an integrated method (i.e.; based on the feature selection and classification) for automatic classification of ACS types from clinically recorded data of patients who have reported to an emergency department. A dataset containing medical records of 809 patients suspected to suffer from ACS was used. For each subject, 266 clinical factors were collected. Initially medical feature selection was performed based on numerous interviews with cardiologists. Accordingly, 40 seminal attributes for classifying ACS were selected. A feature selection algorithm was also applied to find a subset of the features with the best classification accuracy in k-nearest neighbor classifier. This resulted in the reduction of features to seven. Eight different common pattern recognition tools for classification of ACS were subsequently employed. The classification performance of these classifiers was compared based on their accuracy and correctness, computed from their confusion matrixes. Among these methods, multi-layer perceptron showed the best performance with the 83.2% accuracy. An integrated classification approach based on AI and appropriate computerized feature selection algorithm can be used as an effective technique for ACS diagnosis and classification.
The issue of soft power in late 20th century found great importance which after Soviet Union breakup, it came more important in 90s decade. With emergence of globalization and expansion of international interactions, traditional and classical issues would no longer meet the interests whereby it is needed to reform policies and attitudes which this is due to the fact that the concepts of security and power have been changed a lot in these periods of time. The issue of soft power as a unilateral and hegemonic power has found a special position in America\'s foreign policy particularly in international interactions. According to the necessity of this issue during the controversial years with the relationship between Iran and west after Islamic Iran revolution, a tangible change appeared in America\'s foreign policy after the event of 11 September. In present paper, It has been attempted to identify the soft power and its dimensions and America\'s foreign policies opposing to Iran Islamic republic which a strategy would be represented in the end.
In this paper we introduce a new fuzzy Monte Carlo method for solving\nsystem of linear algebraic equations (SLAE) of the form Bx = f over the possibility\ntheory and max-min algebra, F = {[0, 1], = max,\n = min}. To solve the SLAE,\nwe use a fuzzy estimator and ergodic fuzzy Markov chains. This new approach works\neven for cases with coefficient matrix norm greater than one.
In this article , at first, we will investigate the approaches of pattern recognition and then we explain the importance of pattern recognition by its structural information which has been called structural pattern recognition method .In continue , we investigate one of the approaches for recognizing the noisy patterns which is called Lyon’s algorithm. This algorithm has been proposed by Lyon. This algorithm is used for recognizing string patterns and is an error correcting parser in context free grammars. In this paper we state disadvantages of Lyon’s algorithm and then introduce a new algorithm for its improvement. One of the problems of the Lyon algorithm is the cubic time complexity and the quadratic space complexity that we suggest a new algorithm with a new data structure for improving problems in the Lyon algorithm . a new algorithm by using linked list list data structure and some changes in procedure of the Lyon has reduced the time complexity from cubic to O(n*R) and also has reduced amount of wasting of the memory to the zero.
