Smart Grid and Renewable Energy (SGRE) , 2012, DOI: 10.4236/sgre.2012.34045
Abstract: In the framework of liberalized deregulated electricity market, dynamic competitive environment exists between wholesale and retail dealers for energy supplying and management. Smart Grids topology in form of energy management has forced power supplying agencies to become globally competitive. Demand Response (DR) Programs in context with smart energy network have influenced prosumers and consumers towards it. In this paper Fair Emergency Demand Response Program (FEDRP) is integrated for managing the loads intelligently by using the platform of Smart Grids for Residential Setup. The paper also provides detailed modeling and analysis of respective demands of residential consumers in relation with economic load model for FEDRP. Due to increased customer’s partaking in this program the load on the utility is reduced and managed intelligently during emergency hours by providing fair and attractive incentives to residential clients, thus shifting peak load to off peak hours. The numerical and graphical results are matched for intelligent energy management scenario.

Abstract: University Science Parks in China were the outcome of commercialization of the Research and Development grants and the proximity of the Higher Education Institutions and enterprise’s association. The Chinese government considers University Science Parks as a key ingredient in the nation’s inventive system. The continuous success and achievements of the TusPark are no exception. Along with the government backing, TusPark exploits different efficient tactics to encourage Science and Technology marketization, inventive actions, and nation’s economic development. However, TusPark also encounters various external and internal institutions; it has fetched its benefits into complete production and developed to the utmost prominent China’s University Science Park. The evolution flight of TusPark is exceptional; however, its skills can aid towards the interpretation of the science parks within the progressive and further developing nations in the proliferation’s framework. The functional development and progress and, various strengths and challenges of TusPark were reviewed in this paper.

The proposed controller utilizes the principle of adaptive one step ahead control and aims at reducing the energy consumed for heating or cooling a building. The design steps are discussed in details and a proof of global stability is also provided. Also, the performance of the proposed controller is demonstrated on a simulated building thermal model.

Point of sale tobacco advertisements in India
Chaudhry S,Chaudhry S,Chaudhry K
Indian Journal of Cancer , 2007,
Abstract: Background : The effect of any legislation depends on its implementation. Limited studies indicate that tobacco companies may tend to use such provision for surrogate advertising. The point of sale advertisement provision has been placed in the Indian Tobacco Control legislation. The study was undertaken to assess the Indian scenario in this regard. Objective : To assess if there are any violations related to provision of point of tobacco sale advertisements under India′s comprehensive tobacco Control legislation in different parts of India. Materials and Methods : Boards over various shops showing advertisements of tobacco products were observed in the cities of Delhi, Mumbai, Kolkata, Trivandrum and Jaipur, between September 2005 and March 2006. Results : The point of sale advertisements mushroomed after the implementation of 2004 tobacco Control legislation. Tobacco advertisement boards fully satisfying the point of sale provision were practically non-existent. The most common violation of point of sale advertisements was the larger size of the board but with tobacco advertisement equal to the size indicated in the legislation and remaining area often showing a picture. Invariably two boards were placed together to provide the impression of a large single repetitive advertisement. More than two boards was not common. Tobacco advertisement boards were also observed on closed shops/ warehouses, shops not selling tobacco products and on several adjacent shops. Conclusion : The purpose of the point of sale advertisements seem to be surrogate advertisement of tobacco products, mainly cigarettes.

Shahab Fazal, Arshad Amin
Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.22016
Abstract: Human actions rather than natural forces are the source of most contemporary changes in the state and flows of the biosphere. Understanding these actions and the social forces that drive them is crucial to understanding, modelling and predicting local, regional as well as global environmental change and also for managing and responding to such change. The present study investigates the patterns of urban land transformation in Srinagar City, which lies in fragile hill eco-system of Kashmir valley. The results points towards unplanned and haphazard urban expansion and transformation. These transformations have severely destroyed the water bodies both in terms of area as well as its quality.

Arshad Amin, Shahab Fazal
Journal of Geographic Information System (JGIS) , 2012, DOI: 10.4236/jgis.2012.43027
Abstract: The increasing population and economic activities are putting pressure on the available land resources. Human population and their use of land have transformed the terrestrial biosphere into anthropogenic biomes (anthromes). The present study analyses the urban land use/cover change and land transformation in Srinagar city which is located in the valley of the hill state of Jammu and Kashmir. A change detection analysis was performed to determine the nature, extent and rate of land use/cover change and transformation over 30 years of time period. The results show that the city has expanded significantly at the cost of non built-up land which has decreased in its area. Significantly there was not only the expansion of city area but also there were interchange of land between different land use/cover classes in the study area.
Mechanical and Thermal Properties of Chemically Modified Epoxy Resin  [PDF]
Sumeera Ikram, Arshad Munir
Open Journal of Synthesis Theory and Applications (OJSTA) , 2012, DOI: 10.4236/ojsta.2012.13007
Abstract: Diglycidyl ether of bisphenol-A (DGEBA), having number average molecular weight (Mn) 375, was modified by incorporating the hydroxyl terminated polybutadiene (HTPB) based prepolymer using isophorone diisocyanate as a coupling agent. To increase the compatibility between the epoxy resin and HTPB part, polar groups were introduced in the later to achieve physical and chemical interactions between the two phases. The finally modified DGEBA system was cured with amine based hardener. FTIR and 1H-NMR were used to monitor the whole modification procedure. The rubber particles size and distribution was monitored as a function of HTPB contents in the resin system using scanning electron microscopy (SEM). The mechanical, thermal and thermo-mechanical properties have shown that the tensile strength, toughness, ductility and impact strength of the modified cured system have been successfully increased at some optimum HTPB contents without affecting the inherent thermal and thermo-mechanical stability associated with DGEBA resin system. Some of the mechanical properties like flexural modulus, tensile modulus and compressive strength decreased with increasing rubber contents.

Arshad Amin, Shahab Fazal
Journal of Geographic Information System (JGIS) , 2015, DOI: 10.4236/jgis.2015.72018
Abstract: Rapid, unplanned and uncontrolled urbanization causes disorganized growth. The patterns of urban development are changing natural landscapes and their dynamics. This has necessitated understanding of spatial patterns of urbanization and prompted research. Urbanization being a dynamic phenomenon has been facing ambiguities regarding methods to study its dynamism. It has made operational, a wide-variety of spatial metrics methods utilizing multiple dates of remotely sensed data. The present work carries out the quantitative and qualitative analysis of urban growth of Srinagar by using Urban Landscape Analysis Tool (ULAT). Urbanized Area (UA), Urban Footprint (UF) and New Development (ND) maps are generated to quantify the degree of urbanization based on spatial density of built-up area. Comparative analysis of these maps in relation to the built-up spread pattern indicates that mostly the environs of the Srinagar city which includes mostly agricultural, vacant and marshy areas prominently in northern, western and southern areas contribute to the development of the city.
