Despite emerging of modern architecture and losing identity in new constructions, typology is assumed as one of the important subjects that try to identify applied techniques to achieve past local identity creating elements and patterns and to use them in today architecture as modern form. Traditional housing structures act as primary formative core in cities and also the existing architectural elements and monuments in them are surely assumed as precious heritage for review, analysis and presentation of suitable local architectural patterns. According to the conducted observations and studies, today housing constructions are usually built regardless of climatic and local patterns and they encounter several problems either in terms of identity or climatic dimension and energy consumption. Many residential complexes have been built during several years in most of which Persian traditional and local patterns have been forgotten and or utilized symbolically and as cases but they have neither climatic and functional efficiency nor effective in terms of identity. Inter alia, these patterns, central yards, open and semi-open spaces, extroversion and introversion have been highly addressed especially in cities placed in tropical climate. Research criteria and objectives: The main problem of this study is lack of certain pattern or method to give identity to modern housing architecture that has been derived from original Persian local architecture. Methodology: The above-said research is a qualitative studied methodology and the related diagrams are presented for data analysis with descriptive and analytical structure to examine patterns of semi-open spaces at northern Iran and also the used methodology is based collection of valid evidences from the sources in EBD. Accordingly, efficiency-based design is an approach in designing process that tries to employ evidences and case samples to meet the needs to design based on making decisions with high utility of responsiveness. Research results: It is inferred from the primary investigations based on the given elements that using semi-open spaces of local patterns in design of modern houses may provide climatic comfort and even mental health for inhabitants and their identity structure as possible. Thus, it can be found that the role of local identity may depend on these criteria (e.g.….) in the process of architectural design of modern houses.

The main focus of the present work to investigated the effect of the gamma irradiation on the optical properties and energy band gap of the Nano composite polyvinyl alcohol (PVA) doped with silver nanoparticles (Ag) thin films were prepared using the signification and casting techniques. The Gamma irradiation emitted from 60Co source with irradiation dose (1, 3, 5, 8, 10 and 15) kGy. Absorption and transmission spectra have recorded in order to determine the type of electronic transitions and find the value of the optical energy gap. The results indicated that indirect transition expected and the value of energy gap decreased from (4.7 eV) for unirradiated nanocomposite (PVA/Ag) film, after irradiation energy gap is decrease with the increasing doses irradiation. The radiation effect on the linear coefficient of absorption (α), refractive index (n), coefficient of extinction (k), real and imaginary dielectric constants for all samples were studied.

lidar (Light Detention and Ranging) technology is a performing remote sensing application, able to provide range and time resolved measurements of the backscattered (or re-emitted after a stimulation) light from a target invested by pulsed laser light. In this research, after a brief introducing of the different parts of a LIDAR system, it has been studied to design and optimize a concentrating optical system by means of Matlab software.

The biography of the messenger of Allah, peace be upon him, represents a fertile ground for us to reflect and take good example in dealing with matters and managing all the crises and the difficulties and speeches that concern us.he had a unique way of crisis management policy in accordance with good wisdom. He had his acumen to end the dispute definitively, while protecting the Muslim community from the effects of the crisis. he was working to take advantage of the situation resulting from the crisis in reform and development, and to take preventive measures to prevent the recurrence of the crisis or the occurrence of similar crises.And you are to see the effects of this wisdom in those treatments in the noble Prophet’s biography before and after the first revelation. After his mission (may Allah bless him and grant him salvation), Muslims faced many different crises, between the torture Whoever became a Muslim and the Meccan boycott of the Hashemites , then after the migration the confrontations between Muslims and infidels took a more severe direction . From what is depicted in the Quran in the event of Al-Ahzab, the Almighty said:" Behold! they came on you from above you and from below you, and behold, the eyes became dim and the hearts gaped up to the throats, and ye imagined various (vain) thoughts about Allah!(10)” In that situation were the Believers tried: they were shaken as by a tremendous shaking(11)”
