اسلام در تمام شئون خود دینی اجتماعی است؛ چنانچه یکی از آشکارترین وجوه هویتی جامعه و شهر اسلامی، مسجد است که به سبب بعد عقلانی و معنوی ویژه خود همواره نقشی بنیادی داشته است. به نظر می رسد امروزه این نقش برجسته مساجد در سازماندهی ساختار کالبدی و اجتماعی شهرهای اسلامی، و در شهرهای معاصر ایرانی- اسلامی در حال کم رنگ شدن است. از این رو، توجه اصلی این مقاله به شناسایی ویژگی های معنایی و کالبدی خاص مساجد کهن در شهرهای ایرانی اسلامی است که می توانند امروزه نیز به عنوان عامل نظام بخش کالبدی و اجتماعی شهر مسلمانان ایفای نقش نمایند. به این منظور و به عنوان نمونه پژوهی مسجد وکیل و مسجدفاطمه الزهرا شیراز انتخاب شده است. ذکر این نکته ضروری است که پژوهش حاضر از روش تطبیقی- تحلیلی و روش تاریخی و مقایسه ای با استفاده از طیف لیکرت و آزمون پایایی آلفای کرونباخ و ابزار گردآوری داده: مطالعات کتابخانه ای و مشاهدات میدانی بهره گرفته است. یافته های تحقیق نشان می دهد که مسجد وکیل، مسجدی است که نگاهی گذارا به فرآیند شکل گیری و تاثیرگذاری آن در بافت تاریخی شیراز بیانگر تاثیر شگرف آن در تلفیق مطلوب زندگی روزمره شهروندان و عملکردهای سنتی مساجد و مکانی مقدس است که در دوره های مختلف تاریخی تا پیش از قرن حاضر، محل برگزاری رویدادهای مهم اجتماعی و برقراری تعاملات مطلوب اجتماعی میان شهروندان بوده است. در حالیکه مسجد فاطمه الزهرا که در دوران معاصر ساخته شده است و فاقد تاثیرگذاری اثربخش کالبدی و اجتماعی شهری می باشد که می توان یکی از عوامل اثرگذار بر بی اعتباری قرارگاه های رفتاری آن را کمرنگی و تضعیف عنصر جلوخان در ساختار کالبدی آن در حوزه مولفه های سازمان فضایی، انعطاف پذیری، تناسبات بصری، نشانه ، غنای حسی، و خوانایی دانست.

Investigation on modern history of urban planning in Iran shows that there are three approaches in the subject under discussion: “Modernism and Westernism”, “Traditionalism and anti-Westernism”, and “Adopt and Adapt”. Proponents of the first approach believe in encouraging methods to use the external concepts. The second, is the idea about ​​cultural and religious values, ​​thereby everything with nontraditional orientation is rejected. In the third approach the thinkers believe that if the parts of tradition are synthesized by modernity, culture and religion can adapt themselves with the development. The purpose of this study is to evaluate the adaptation of traditional urban design patterns of Islamic-Iranian cities in incompatible district of new Iranian cities (spontaneous settlements) and to focus on the application of the third approach in the current situation of Iranian cities. On this basis, the method of comparative analysis has been applied to survey the differences and similarities between historical districts and spontaneous settlements. Studies show that there are rather similarities among physical - spatial parameters (such as structural and environmental criteria) between the two types of districts; because both of these residential districts formed as organic structures that are unstable against unexpected risks and earthquake. However, there are the differences between these two types of districts in organized and formed periods. Despite historical districts that have been consolidated and organized during hundreds of years, spontaneous urban textures formed quickly and without any plan and planning. Meanwhile, the historical districts have usually integrated townscapes and unique materials such as clay, bricks or stone, while this character (integrated townscape and unique materials) never have been seen in the spontaneous settlements. There are similarities in economic and socio- cultural characteristics between residents in the two the types of districts. The residents living in poor economic condition, but under a very strong socio-capital and traditional beliefs; There can be seen several socio-cultural and particularly religious characteristics in people of historical residential districts that are similar with the spontaneous residential places, such as “strong relationship among families, friends”, “hospitality”, “mutual relationship among family members”, strong religious beliefs and the needs for privacy and security. However, these communities are different in some principles such as quality of life and spatial and physical qualities especially in favorable and beautiful urban landscapes. So it can be extracted and adopted excellent principles from traditional and historical districts and adapt them to the inappropriate modern urban districts. With regard to the existence of these similarities, we explain applicable principles of the spatial characteristics and designing quality in the historical district of Yazd to apply in Baghshater District in Tehran as a spontaneous settlement. Findings show that we can use several solutions to reconstruct this zone included: 1) land readjustment as the suitable solution in Baghshater District with regard to the familial residential pattern in historical zone of Yazd such as Fahadan District. 2) Focusing on the traditional concept of mutual relationship in residential houses. 3) Emphasizing on the hierarchy of The entrances and exits of the residential units.

The electronic industry suffers a rapid changing and highly rival environment. Thus, firms have an essential need to strive for acquiring the competitive advantage. Strategy Organizational Agility (SOA) is a tool which enables to assist firms to attain the competitive advantage. Therefore, this study benchmarks the core competencies from a case study within the supply chain network and establishes a set of attributes for augmenting SOA. A novel multi-criteria decision-making structure is proposed to deal with the complex interrelationships among the aspects and attributes. Radial basis function (RBF) neural network can use linear learning algorithm to complete the work formerly handled by nonlinear learning algorithm, and maintain the high precision of the nonlinear algorithm. However, the results of RBF would be slightly unsatisfactory when dealing with small sample which has higher feature dimension and fewer numbers. Higher feature dimension will influence the design of neural network, and fewer numbers of samples will cause network training incomplete or over-fitted, both of which restrict the recognition precision of the neural network. The competence and accountability indicators can the continuously increasing level of agility to be effective. According to the analysis chart production and product design performance indicators alone cannot level a considerable amount of agility to change. But reducing the level of the index level of agility is reduced. Flexibility indices speed and agility level changes can also affect the organization. But with increased levels of these two indicators increased agility rate change indicators will be more flexibility. The results showed that customer knowledge management impact on organizational agility and organizational effectiveness and customer knowledge management through organizational agility has significant positive impact on organizational effectiveness. Finally, some practical suggestions, future research suggestions and research limitations are presented.

Comparison of parametric and fuzzy analytic hierarchy process in land evaluation (Case study: Varamin region)(مقاله علمی وزارت علوم)

حوزه‌های تخصصی:
تعداد بازدید : ۲۶۸
In last decades, the skillful planning of land resources has become a major issue for rural development. The development of cultivated areas becomes gradually impossible due to ever increasing population growth and urban development. Fuzzy logic is preferred to Boolean logic for land evaluation, because fuzzy techniques lead to estimate for land use suitability on a continuous scale and can therefore, be more informative than the Boolean technique. The objective of this study is to apply fuzzy set methodology in the context of a decision making process known as the Analytic Hierarchy Process (AHP) to land evaluation for irrigated wheat. The results revealed that the results obtained with fuzzy AHP method are in better agreement (R2=0.911) with the observed yield as compared to those obtained with parametric method (R2=0.804). Although, the fuzzy AHP provided more efficient and accurate results than parametric method, the choice of membership functions, width of the transition zones and weight values are determinant to achieve its realistic results in land suitability assessment.

تعداد بازدید : ۲۵۵ تعداد دانلود : ۲۵۳
Hail phenomenon is one of the hazardous weather phenomena that can make the highest amount of damage to farms, gardens, cars, rooftops, etc. in a very short time (a few minutes), depending on the diameter of the particles. One of the best ways to study this devastating climatic phenomenon is the use of atmospheric instability indices. The indices which are calculated with the help of radiosonde data give a fairly comprehensive vision regarding the occurrence of such phenomenon. In this study, the incidence of moderate to severe hail is investigated in the period of 1990-2010. First, the atmospheric codes related to hail phenomena were applied to extract the data, then radiosonde data in intended time were received and applying the RAOB software, the physical status of atmosphere was studied. In the studied period, two hail examples were reported on November 27, 2008 and December 5, 2008. In the first instance of hail that occurred on November 27, 2008, the status of some indicators was calculated and it was found that LCL was at an altitude of 284 meters, CCL at an altitude of 1582 meters, LFC at an altitude of 6230 meters, the ice surface at an altitude of 3278 meters, the LI index was -0.2, the K index was 25.7 ° C, and PWC was 28 mm. In the above mentioned conditions, there was a hail with a diameter of 25.4 mm. In the second instance of hail that occurred on December 5, 2008, the status of some indicators was calculated and the results showed that LCL was at an altitude of 280 meters, CCL at an altitude of 1762 meters, LFC at an altitude of 2271 meters, the ice surface at an altitude of 2771 meters, the LI index was -1.4, the K index was 27.1 ° C, and PWC was 23.6 mm. In the above mentioned conditions, there was a hail with a diameter of 3.6 mm. Given that in many ways, the status of most atmospheric indicators in the two above examples of hail were close to each other, it turns out that in similar circumstances, the greater the distance the ice level gets to the summit of cloud, the greater is the probability of hails larger in diameter. The value of this distance for November 27, 2008 was at approximately 6384 meters and for December 5, 2008, it was at about 5012 meters.

Creation of urban identity is the important subject in architecture and urban design. So, this article foci’s on the Creation of Identity in Urban context with Participation approach in Architecture and Urban Design. Corporate architecture is an architectonic discipline which focuses on designing and constructing buildings, spaces or environments with the aim of meeting the needs of a business community. Its objective is spatial perception of corporate values by the company’s employees and customers because for motivation and communication, conveying the corporate values and philosophy clearly is of essential significance for success. Place identity could best be understood as that which makes a place unique. The identity concept from the point of cities and architectural products includes a wide definition covering natural, geographical and cultural products and social life norms. Urban identity, architectural identity and the urban images about them are sometimes formed by very different components in a long period in urban space. In recent days, we often come across with the problem of cities to enter a new architectural and urban formation process in a dimension of losing their original identities. In this context; the city identity is formed in the togetherness of urban participation and natural and cultural values which are required to preserve, unique architectural and spatial characteristics, social accumulation and life style. City identity concept having spatial, social, cultural and economical dimensions should be handled with a totalitarian approach, it must be qualified as a collective result including the urban participation and every interaction which provided the city to reach social participates.

گلخانه های خورشیدی از دیدگاه انرژی، از جمله راه حل های ساختمانی غیرفعال هستند که بوسیله استفاده از تابش خورشید، انرژی خورشیدی را برای ایجاد گرمایش در فضاهای جانبی جذب می کنند. در این پژوهش با استفاده از پنج متغییر جهت گیری، زاویه شیب و ابعاد، مصالح نورگذر، انتقال حرارت و حفظ انرژی و با استفاده از داده های اقلیمی محدوده مورد مطالعه که در بازه زمانی (2005-2015) از ایستگاه سینوپتیک هواشناسی فرودگاه کرمانشاه گردآوری شده است. مدل بهینه گلخانه خورشیدی در اقلیم مورد نظر با کمک نرم افزارهای شبیه سازی و ارزیابی انرژی بررسی و تحلیل شده است. بر اساس نتایج این پژوهش در طول ماه های گرم سال (شش ماه اول) جهت هایی که زاویه بیشتری نسبت به جنوب دارند انرژی بیشتری را دریافت می کنند؛ اما این موضوع در ماه های سرد سال (شش ماه دوم) تقریبا حالت عکس به خود می گیرد، به گونه ای که زوایای نزدیک تر به جنوب انرژی بیشتری را دریافت می کنند که با توجه به هدف از طراحی گلخانه که همانا کمک به کاهش بار گرمایشی در طول فصول سرد سال می باشد، این گونه جهت گیری برای ما مناسب تر خواهد بود که با توجه با آن می توان دریافت که مناسب ترین جهت گیری به منظور دریافت حداکثر انرژی خورشید در شش ماه دوم سال چرخش 10 درجه ای از سمت جنوب به سمت غرب می باشد. همچنین با توجه به نتایج حاصله می توان دریافت که بیشترین بازده در دریافت انرژی خورشید در شش ماه دوم سال در محدوده مورد مطالعه علاوه بر زاویه آزیموت 10 درجه به سمت غرب مربوط به زاویه شیب 50 درجه نسبت به سطح افق گلخانه می باشد از این منظر بهینه ترین طول گلخانه خورشیدی 6 متر و بهینه ترین فرمول محاسبه عمق (عرض) آن از رابطه COS(50)=W/h قابل محاسبه است. همچنین به منظور بهبود عملکرد گرمایشی در گلخانه می توان از پنجره های با شیشه دو جداره و نیز پنجره هایی با شیشه های کم گسیل همراه با عایق کاری متحرک درونی استفاده کرد، که باعث کاهش ضریب انتقال حرارت در پنجره شده و درنتیجه سبب کاهش اتلاف انرژی در گلخانه می شود.

Western Scientists throughout history express various definition and goals for power; Most of political scientists believe that power is the main concept of politics and power is the goal of politics. They categorized the power into varies classifications. In this paradigm, power means Material instruments and there is no any place for the immaterial instruments. In the other hand Islam as a Monotheistic religion not only mentions the material aspects of political concepts; definitions that provided by Islamic scholars have differences and sometimes contradictory with western definitions. Power is part of politics (not purpose of politics) and it has not intrinsic value. Purpose of politics are guidance of the human to perfection, Establishment of order and justice and Prevention of cruelty. Unlike the western concept, the source of power and the source of its legitimacy is Allah. So in this paper I try to introduce the theory of power in Islam. The main question of this paper is: what is the definition of power in Islam and what are its differences with the western definitions.
