 Abstract

The paper proposes a survey conducted on the various Methodologies used for monitoring vehicles using CAN protocol. Enabling a sustainable mobility is one of the primary goals of the smart city vision where the development of intelligent parking system represents a key aspect. Parking space monitoring and allocation is the solution to the parking problem faced in cities. Through this survey, we have analyzed few fine features and scant flaws in the existing systems. These failing factors affecting the overall performance of the system can be overcome by further research and development.

 Abstract

In the present work, this paper presents the design an antenna and analysis of ultra wide band (UWB) applications for satellite communications. By using a photo voltaic cell the radiating patch element of a patch antenna was replaced. Antenna is a one type of transducer converts electrical energy to electromagnetic energy in form of electromagnetic waves. Here, to design a patch antenna structure based on a photovoltaic solar cell. It is used to collecting a radio frequency (RF) as well as photo-generated current. To improving efficiency is used for solar cell in patch antenna. A simulation allowing measuring the performance of the antenna, with a n and p type silicon material and analyzing its parameters such as the gain, directivity, radiation pattern, reflection coefficient(S11) and bandwidth. The performance of proposed antenna has been simulated and designed using HFSS software.

ABSTRACT The most challenging issue in Construction industry is to improving the production efficiency. Many research have been done in the past, however a deeper understanding is still needed to improve the labour productivity. The main outcome from the literature is that there is no standard definition of productivity. It covers the construction labour productivity definitions, aspects, factors affecting it. The productivity of labour is particularly important especially in developing countries, where most of the building construction work is still on manual basis. The aim of this study is to get the latest information and to identify the key factors that affect the labour productivity in and around Coimbatore. So survey is carried out through questionnaire and distribute to respondents who work at various projects in wide area in Coimbatore and the questionnaires are rated by project managers, experienced engineers and also with labours using their past experiences. And the data's are collected and analysed; using this the affected factors are identified and ranked, through this necessary steps are provided to improve the labour productivity.

 Abstract

Sustainable development cannot be achieved without a major contribution from agriculture. The present study was carried out in Purulia-I block of Purulia district in West Bengal. This research was motivated by the concern that most farmers face heavy rains during the growing season and that crop damage and yield losses due to heavy rains cause extensive losses among farmers. The present study indicates that the total 287 hector area was damaged due to excessive rainfall in Purulia-I block where 496 hector area shown under vegetable cultivation. Total cultivable area in Purulia-I block was 19334.19 hector. It is also clearly notified that Dihdiha Gram Panchayat was highly affected (65.15%) by heavy rainfall where Manara Gram Panchayat (51.85%) was lowest in this block and the average damaged area under vegetable cultivation in Purulia-I block is 57.86 percent. Excessive rainfall has a detrimental impact on horticultural crops productivity but rainfall during the specific growth stage is rarely used in efficiency analysis. This study focuses on this available point and examines the influence of rainfall specifically encountered during the sowing stage and early vegetative growth stage and the flowering stage of different horticultural crops in Purulia district.

 Abstract

Unsteady boundary layer flow of an incompressible fluid over a stretching surface in the presence of a heat source or sink is studied. The unsteadiness in the flow and temperature fields is caused by the time dependence of the stretching velocity and the surface heat flux. The nonlinear boundary layer equations are transformed to nonlinear ordinary differential equations containing the Prandt l number, heat source or sink parameter and unsteadiness parameter. These equationsare solved by applying Fuzzy Adomian technique and compared with the existing numerical results obtained by using Shooting with Runge Kutta method. This focuses on solving the nonlinear ordinary and partial differential equations using Fuzzy Adomian decomposition method

Utilization of Solar PV Panels Innovation for housetop establishments in private and also business foundations is ending up increasingly well known as an option reasonable eco-accommodating, non-dirtying wellspring of power. India's Objective: 175GW from sustainable power sources by 2022 Break up:100 GW from sun oriented, 60 GW from the breeze, 10 GW from biomass and 5 GW from little hydroelectric ventures. 100GW = 60 GW of utility-scale ventures (both solar based PV and CSP) like solar powered parks + 40 GW of housetop solar oriented applications for business clients and family units, together with some little scale plots and off-lattice limit. While Solar oriented Photovoltaic Frameworks do have a few advantages, there are additionally different issues which become an integral factor at the season of establishment, upkeep and amid crisis circumstances, for example, amid a fire,etc.

 Abstract

This paper presents a small size ultra wideband (UWB) antenna for wireless personal area network applications. The proposed antenna covers the impedance bandwidth of 3.1 to 10.6 GHz frequency range in free space. The design parameters for achieving optimal performance are investigated. A tapered microstrip feeding is employed to enhance the antenna matching. The operation and the characteristics of the proposed antenna are also analyzed. Good agreement has been obtained between the simulation and experimental results. The simulated and measured radiation patterns have demonstrated that the antenna is nearly omni-directional over the entire band.
