Abstract:

An energy analysis which based on first law of thermodynamics is carried out for single, double, triple effect series flow vapour absorption system with LiBr-H2O working fluid pair. The coefficient of performance (COP) for all systems is obtained for specified operating conditions. As expected, the COP increases from single effect to triple effect vapour absorption systems. Finally, COP for quadruple effect series flow vapour absorption system is evaluated and results show that this system has highest COP among all multi-effect systems. The effect of high temperature generator, evaporator temperature, condenser temperature and heat exchanger effectiveness is also evaluated for triple and quadruple effect series flow vapour absorption system.

Abstract:

Utility companies have not been achieving maximum profit due to electricity and meter thefts. Prepaid energy metering system with GSM interface being proposed in this work will help to improve the profit margin of the utility companies. Detection of electricity and meter thefts by the utility companies will enhance efficiency in transaction and communication with their customers. This is achieved through the use of tamper and meter theft detection units (TDU & MTDU) with GSM Module/Modem. The detection switches are connected at the back and the cover of the meter to prevent meter theft and tampering. When the cover of the meter is tampered with, the microcontroller sends appropriate signal to the server via GSM interface and the server in turn sends a signal that disconnects the meter and an alert to the customer‟s phone notifying the customer of the incident. Power is restored automatically, when the anomaly is cleared. A back-up battery is incorporated to keep the circuit active, when there is power failure so that the utility company will be notified, if there is an attempt to tamper or by-pass the supply cable..

Abstract:

The present study aims at studying the effect of RECRON 3S Fibre on the CBR behavior of the fine grained soils when applied in various percentages. So for the same purpose we have used the soil procured from a site within campus of GCET, Chak Bhalwal, Jammu. The study aims at finding out the possibility of using Recron 3S as a stabilizing agent in improving the California Bearing Ratio (CBR) value and strength properties of the fine grained soils. Recron being a low cost alternative for improvement of much needed hike in the CBR values of soils, has being studied. Recron 3S fibre helps in improving soil subgrade strength of silty soil. It is evident from the CBR test results that CBR value of untreated soil increases from 7.84% to 11.10% with addition of 0.30% Recron 3S fibre. From the results it is also observed that addition of further Recron 3S fibre to the soil in the quantity of 0.60% of dry weight of soil has very little further increase in the CBR value..

Abstract:

Traffic management is a major problem at all busy junctions or intersections. The rapid growth of traffic at an intersection might cause problems like road accidents, traffic congestion, conflicts and bottleneck situations. Traffic signals are the most suitable method to monitor and control road traffic at an intersection. It can be achieved by providing automated volume based traffic signal system. Improvement of traffic performance in terms of safe and efficient movement of traffic at road networks and terminals it is done by systematic traffic studies with engineering applications. This includes planning and geometric design on one side and regulating and traffic control on the other. An intersection is a crucial point of conflict and congestion in road networks the capacity of urban road network depends upon traffic signals. The major problems like accidents and hazards can be minimized using proper traffic survey......

Abstract:

Public transport is a basic service that must be provided to any society. An effective public transport system is the system that can provide adequate service coverage to all community groups, especially the low-income group, the elderly and the disabled. For performance evaluation, performance metrics are widely implemented; for this purpose transit accessibility is used in this study as it reflects the ease of reaching transit service and its convenience as a mode choice. This study aims to assess transit accessibility in Wadi Al-Seer, one of the main districts in Amman. Accessibility was measured on the basis of the percentage of service coverage area and served population. The analytical framework......

Converting AC/ AC for industrial applications, it is required by the operating characteristics of the sources and loads. Alternating electrical sources are showing constant valuesof voltage, frequency, power and phases. They can be single or three-phase types, according to their classifications of power. The AC / AC converters used to vary the effective voltage across the constant electrical loadslike the frequencies, that are known as controllers or regulators AC voltage AC.

Abstract:

Generally dumb people use sign language for communication, but they find difficulty in communicating with others who don't understand sign language. This project aims to lower this barrier in communication. It is based on the need of developing an electronic device that can translate sign language into speech in order to make the communication take place between the mute communities with the general public possible. A Wireless data gloves is used which is normal cloth driving gloves fitted with flex sensors along the length of each finger and the thumb. Mute people can use the gloves to perform hand gesture and it will be converted into speech so that normal people......

Abstract:

Pure, silver (Ag) and gold (Au) doped tungsten trioxide (WO3) nanostructure films were prepared by electron beam evaporation technique on glass substrates. The structural, compositional, surface and optical properties were investigated using XRD, EDS, SEM and UV-Vis-NIR spectrometer. From XRD results, the crystallinity of the films decreased after adding the dopants to WO3. The surface morphologies were strongly influenced by the dopants. The doped films have rough surface than pure WO3 films. The optical studies showed that the transmittance and band gap was decreased with dopants. The obtained band gap values for pure,Ag and Au are 3.4, 3.24 and 3.04eV, respectively..
