K. Bharatha Babu, G. Nanthini

Abstract:  Fast Fourier transform has been used in wide range of applications such as digital signal processing and wireless communications. In this we present a implementation of reconfigurable FFT processor using single path delay feedback architecture. To eliminate the use of read only memory’s (ROM’S). These are used to store the twiddle factors. To achieve the ROM-less FFT processor the proposed architecture applies the bit parallel multipliers and reconfigurable complex multipliers, thus consuming less power. The proposed architecture, Reconfigurable FFT processor based on Vedic mathematics is designed, simulated and implemented using VIRTEX-5 FPGA. Urdhva Triyakbhyam algorithm is an ancient Vedic mathematic sutra, which is used to achieve the high performance. This reconfigurable DIF-FFT is having the high speed and small area as compared with other conventional DIF-FFT.

EFFECT OF GLOBAL RECESSION ON INDIAN REALTY SECTOR AND ITS FUTURE DEVELOPMENTS

Author(s):
Oshma Rosette Pinto

Abstract: The recession around the globe from 2005 till present has been considered as the toughest phase compared to Great Depression in 1930’s. This had led the collapse of almost all large financial institutions, banks and stock markets around the globe. This indirectly affected the housing market that resulted in dispossessions, proceedings and extended vacancies. In India the effect on Reality sector was decrease in demand for Real estate in terms of Demand and supply as most of the working population had to undergo reduction in salaries and few layoffs. The Reduction in Rentals of commercials, Projects became stagnate, Deceleration in infrastructure projects, troubles to get fund, Unemployment and Shortage of skill workers forced the builders to reduce their prices. This paper attempts to analyze the impact of global recession on the reality sector of India, makes an effort to analyze the present overall Realty sector situation, and examines what policies are taken by Indian Government and business models that can be adapted to overcome the effect of recession.

Abstract: Cloud computing is a model for enabling service user’s ubiquitous, convenient and on-demand network access to a shared pool of configurable computing resources. Cloud computing is a promising technology to facilitate development of large-scale, on-demand, flexible computing infrastructures. But without security embedded into innovative technology that supports cloud computing, businesses are setting themselves up for a fall. The trend of frequently adopting this technology by the organizations automatically introduced new risk on top of existing risk. Obviously putting everything into a single box i.e. into the cloud will only make it easier for hacker. This paper presents an overview and the study of the cloud computing. Also include the several security and challenging issues, emerging application and the future trends of cloud computing.

Social and Economic Sustainability Analysis of Rural Settlements Located in the Hazard-Prone Areas
(Case Study: Villages Surrounding the City of Sanandaj)

Abstract: This study is aimed at analyzing economic and social sustainability of rural settlements in the hazard – prone zones. Accordingly, the present descriptive – analytical study with emphasizing on its practical aspect is trying to identify high risk zones to locate the villages surrounding the Sanandaj City using Geography Information System (GIS) and Analytic Hierarchy Process (AHP). In this regard, for zoning of hazard – prone areas, information layers such as distance from the fault, gradient layer, height layer, distance from the river, landslide layer, and soil type layer were created utilizing the information existent in the database of GIS at Sanandaj Municipality. Finally, hazard – prone zones were identified by applying the technique in ARCGIS10 and its practical functions and algorithms. In the next step, the layers of villages surrounding Sanandaj City were adapted to the prioritized zones and so the villages (Salavat Abad, Dolat Abad, Gazar Dareh, Khalijan, Issa Dar, Hassan Abad) which are located in hazard – prone zoning, were identified. To assess the socio – economic conditions of these villages are used FTOPSIS technique. The studied samples were two Councils members in each village which were selected randomly to survey and to achieve the goal of research. The results showed that economical aspect of the indicator (rural road networks), with ID = E5, and social aspect of the indicator (health facilities), with ID = E8 gained the lowest weights in the minimum, average and maximum fuzzy criterion, and also the indictor of rural power network and its backup services, with ID = E1, and taking care of villages with cultural and historical monuments gained the highest weights in the minimum, average and maximum fuzzy criterion.
