Physico-chemical Assessment of Water Quality of River and the Hydro-biological Study of Algae[ ]


Biological assessment is a useful alternative for assessing the ecological quality of aquatic ecosystems since the biological communities integrate the environmental effects of water chemistry. Algal and water samples were collected from three sites of River Dham (Pavnar, M.S.). viz., Pavnar Ashram (S1), Ghorad (S2) and Morchapur (S3) and analyzed for Water quality variables (physicochemical) parameters. The data was analysed with reference to ISI & WHO standards. It was found that the water is safe for domestic purposes and aquatic life as far as levels of pH, density, surface tension, viscosity, conductance, TDS, alkalinity, DO and chloride concentration. However, the water quality parameters such as total hardness and Ca++ hardness at some stations were beyond the permissible limit. Therefore, it was suggested to remove total hardness and Ca++ hardness to make it fit for consumption. Phytoplanktons encountered in the water body reflect the average ecological conditions and they may be used as indicators of water quality. During the investigation total 53 algal species were encountered and identified.

Automatic High Beam Controller for Vehicles[ ]


The number of vehicles on our roads is burgeoning day by day. This is turn forced almost all this vehicle manufactures to think about the extra safety instruments and electronic controls to attach with these products for giving the users a safety derived in all road conditions through a mass flow traffic. If asked, one should always mention that the right driving is very cumbersome due to the dazzling light problems and the frequent dipping of headlights by manual means that often causes fatigue to the driver particularly at the time of peak traffic. So naturally to get rid of this perennial problem, an automatic mechanism has to come up to dip the headlamp automatically whenever required. For keeping a motor vehicle under perfect control and reins of the driver, different types of controls and accessories are provided in an automobile around the driver's seat, on the dashboard and at the footboard. Simply, an automatic high beam controller is a unit, which can automatically judge when the headlight beam needs to be lowered, and which dip the headlamp from which beam to a dipped beam. Our work proposes an effective automatic control of the vehicle headlamps based on the detection of head lights and tail lights under night time road conditions. This project is about to control high beam or low beam automatically.

Analysis of Adder Using Bist[ ]


Embedded memories consume an increasing portion of the die area in deep sub- micron Systems On Chip (SOCs). Manufacturing test of embedded memories is an essential step in the SOC production that screens out the defective chips and accelerates the transition from the yield learning phase to the volume production phase of a new manufacturing technology. Built In Self Test (BIST) is establishing itself as an enabling technology that can effectively tackle the SOC test problem. However, unless consciously implemented, its main limitations lie in elevated power dissipation and area overhead, and potential performance penalty and increased testing time, all of which directly influence the cost and quality of manufacturing test. This thesis in- troduces study of different adder and their implementation in BIST and also includes two new embedded memory BIST architectures, whose objective is to reduce the cost of test and increase the test quality to improve product reliability and yield.

Study of effect of imbalance in rotor-bearing system due change in radius of gyration[ ]


Disk imbalance is a condition in which the center of mass of a rotating disk is not coincident with the center of rotation. Imbalance in a rotor system is unavoidable and it cannot be completely eliminated. Due to some reasons, such as porosity in casting, non-uniform density of material, manufacturing tolerances, and gain or loss of material during the operation, there is imbalance in rotors. In this study effect of radius of gyration of imbalanced mass on rotor-bearing vibration has been made. The imbalance increases with increase in inertia. A LabVIEW based SCXI system with accelerometer as a sensing element has been used in this study. Vibration signals collected from rotating machinery are often very complex which makes them very difficult to interpret in the time domain. Frequency spectrum analysis using Fourier transform and Continuous Wavelet transform has been made for detecting imbalance and its severity.

Cost Analysis of Rainwater Cistern Systems: A Case Study of Ibadan, Nigeria[ ]


In Nigeria, inadequate supply of pipe borne water is a major concern; hence, many homes depend on groundwater for household uses. However, this supplemental effort is inadequate to meet the demand of the increasing population as the water table declines resulting in a low yield especially during the dry season. Ibadan is the most populous city south of the Sahara with water supply problems and flooding concerns. There is also the associate issue of contamination from septic tanks. Thus, an alternative water supply source in the form of roof-collected rainwater stored in tanks is viable to further supplement the domestic water supply system. However, the economic feasibility of rainwater cistern system is an important factor in its acceptance in the scheme of water resources planning and development. Hence, a hydrological analysis was carried out using 30 years rainfall data from two meteorological stations in Ibadan, a Southwestern city in Nigeria. Since a rainwater-harvesting system (RWHS) is site specific, the volume of water to be harvested and stored per person was determined from three different case studies using the mass balance method. An estimate of the construction cost was carried out based on the prevailing cost of materials in the study area. This article concentrates on the cost analysis of a rainwater cistern system; as compared with the cost of water provision through the existing public water supply system (PWSS). The results revealed that the cost incurred on PWSS is quite low compared to the higher cost of installing a RWHS. However, the RWHS meets the demand of users by providing water in adequate quantity and quality and overcome the risk of contamination and contracting water borne diseases through the consumption of ground water in the study area. The cost analysis of a rainwater cistern in the study area suggests that the system is recommendable for Ibadan and other areas without or with inadequate PWSS. The study also reveals that Ibadan has a very good potential for RWH but some issues will need further research in this regard in the attempt to provide a sustainable solution.

Optimization of High Voltage Arc Assist Interrupters[ ]


The circuit breaker is one of the most important unit in the electrical power system. The protection, stability and continuity of the system depend on the circuit breaker's ability to switch line, load and exciting currents and to interrupt fault currents. High voltage circuit breakers, have to operate with extremely high reliability in the power system to ensure the economical and reliable power distribution. It is observed over the years that most of the failures in circuit breakers are of mechanical nature. Consequently the development efforts over the last decade has been focused towards thedevelopment of high efficiency interrupters which requires low energy mechanism. The first step towards the high efficiency interrupter is the development of Arc Assist Interrupters. In the conventional Puffer type interrupters of a high voltage SF6 circuit breakers, a considerable amount of mechanical energy is used to compress the gas in order to create a gas flow to remove the arc energy. In arc assist Interrupters, arc energy is used to increase the gas pressure required for interruption. This paper discusses the results of detailed flow field and electric field computations. Effect of nozzle shape and thermal chamber volume on the pressure rise is explained. Also capacitive current interrupting performance is estimated based on electric field and gas flow analysis. This paper helps to conclude simulation study using ga flow calculation program which is very useful to understand the mechanism of pressure generation, and it is also very useful to find the data of the optimum design of the interrupter.

Biometric Security Systems and Contemporary Affirmation of State of Art[ ]


Biometrics is playing vital role in applications that are centric to tasks such as identification, verification and classification. One distinctive illustration is a biometric verification structure that concludes the user's authorization by validating the biometric traits submitted by the user. The human traits preferred for biometric systems are universally unique and stable for long time. Moreover the biometrics based verification structures are free from hassles such as opting to complex passwords, remembering and protecting them. The human traits used for biometrics based authentication are user specific and available to others for unauthorized usage is impractical. Henceforth it is quite obvious to consider these biometrics based security structures are strong alternative to traditional password based authentication strategies or effective to progress the security standards of the traditional authentication models. Here in this research article we explore the taxonomy and contemporary affirmation of the biometrics under privacy and security concerns in recent literature.

Characterization of a Battery cell fueled by Bryophyllum Pinnatum sap[ ]


Demand for energy is growing fast worldwide amid depletion in conventional non-renewable resources. Bangladesh being hugely dependent on expensive imported fuel is forced to search for alternative renewable resources such as solar and biomass etc. This paper investigates the potential of the sap of a widely available plant called Bryophyllum pinnatum (life plant) as an electrolyte for use in a battery to generate electricity. The objective is to analyze the cell and optimize its design parameters which will help develop a cost-effective battery. A manually operable mechanical device has been designed and built to squeeze juice from the leaves. The results of the experiment and major parameters affecting the performance of the cell have been discussed in this paper. We identified the major parameters affecting the development of potential difference in a cell between copper and zinc electrodes and short circuit current by varying some parameters of electrodes immersed into the Bryophyllum sap acting as the electrolyte. We observed that the potential difference between the electrodes remains fairly constant but the short circuit current increases proportionally with the increase in the surface area of the electrodes in contact with the sap. The current also increases with the decrease in the gap between the electrodes. Finally a mathematical relationship between the short circuit current and the surface area of the electrodes in contact with the sap has been derived using curve fitting tool of Matlab.
