It has a considerable effect on transportation development in the city. The availability of less space in urban areas has rising demand for parking space principally in central business district. Ill-effects of insufficient parking space in cities are many. Godhra is a well-known city of Panchmahal district in Gujarat which has a population of 1.62 lakh (2011). As the traffic on the existing road system in the Godhra city increases, congestion becomes serious problem. Thus, parking surveys have been carried out for collecting data about parking avaibility and requirement and its effect on present scenario. Fixed period sampling survey method is used for parking demand and Parking space inventory survey is carried out for parking supply at the study area. Analysis shows that peak demand and parking index are almost 1.5 times more of demand than supply and it is alarming stage for parking problem. Requirement of parking has been fulfilled by designing off-street parking facility for on street parking user so that they can park their vehicle safely and it is more helpful to transportation system by increasing utilization of carriage way width. Design of Multi level parking space has been done according to demand and supply available by using ParkCAD(5.0) and as per the SP-12(2015)Guidelines for parking facilities in urban area. Results help in reducing the congestion of on-street parking and diverge the demand to off-street parking. 2019-03-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/8217 Optimal green energy source selection: An eclectic decision Bhowmik, Chiranjib; Bhowmik, Sumit; Ray, Amitava Various researchers have suggested many qualitative and quantitative criteria for green energy management, which are mostly operational in nature and specific to a particular application. The main aim of this investigation is to develop an innovative integrated analytical framework as a benchmark for selecting the optimal green energy source under various sustainable dimensions. Nine major areas likely; energy management, source selection, environmental dimension, social dimension, economic dimension, technical dimension, institutional dimension, sustainability and importance measurement have been considered for this study. The proposed framework for green energy source selection is relatively innovative as the various key factors are integrated for sustainability level of constructs (environmental, social, economic, technical and institutional) with expert judgment levels (both strategic and tactic). The framework helps to identify the optimum green energy source (solar energy) for cleaner future using analytical hierarchy process. The research can potentially help energy managers, policy makers as well as decision makers to measure and improve the utilization of green energy sources for sustainable future. 2019-10-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/8215 SOLAR POWER TECHNOLOGIES, REFRIGERATION AND COOLING SYSTEMS – REVIEW Dadi, Mohsin J.; Vyas, Arjun K.; Sodha, Dhaval R. Energy is the heart of the modern world. This paper provides a detailed review of solar photovoltaic and concentrated solar power technologies. The status of solar photovoltaic technology being commercially developed, subsidized and mature technology is suited for both residential and commercial applications. On the other side, concentrated solar power technology despite having higher capital cost yield higher economic returns hence suited for commercial applications. This paper also provides a review of different solar refrigeration technology and cooling methods. Different cooling systems using various working fluids assisted by solar energy are reviewed. Solar powered refrigeration technologies are classified into four categories: Solar photovoltaic cooling systems, solar thermo-electrical cooling, solar thermo-mechanical cooling and solar thermal cooling techniques which includes sorption, absorption and adsorption systems. In this article we have tried to produce a review based on solar energy collection and coefficient of performance of different refrigeration systems. 2019-01-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/8160 A comparative study of electrochemical degradation of benzoic acid and terephthalic acid from aqueous solution of purified terephthalic acid (PTA) wastewater Sandhwar, Vishal Kumar; Prasad, Basheshwar In this article, studies have been performed on the treatment of benzoic acid (BA), terephthalic acid (TPA) and COD from synthetic binary solution of PTA wastewater. Acid precipitation pretreatment of aqueous solution was performed initially at different pH (2–5) and temperature (15–60 °C). The acid treated solution was re-treated by electrochemical oxidation (EO) and electro-Fenton (EF) techniques using graphite electrodes. Independent operating parameters namely initial pH: (1–9), current density (A/m2): (30.48–91.45), electrolyte concentration (g/L): (0.5–1.5) and electrolysis time (min): (10–90) for EO process and pH (1–5), current density (A/m2): (30.48–91.45), Fe2+ concentration (mmol/L): (0.5–1.5) and electrolysis time (min): (10–90) for EF process were modeled and optimized by central composite design (CCD) in response surface methodology (RSM). The maximum removal efficiencies of the process during EF treatment were 80.45% of BA, 76.83% of TPA and 73.70% of COD with energy consumption (kWh/kg COD removed) – 19.39 at optimum operating conditions. During EC treatment removal capacities were 70.76%, 68.52% and 67.27% with 31.01 (kWh/kg COD removed) respectively. It was observed that EF process was more efficient than EO based on removals of BA, TPA and COD with minimum energy consumption. 2019-08-01T00:00:00Z
