The present work is aimed at assessing the Water Quality Index (WQI) for ground water samples collected from 19 major villages of Narsapur mandal, Telangana state. Telangana state is classified as hard rock area where surface water resources are limited, with the result, groundwater has become a major source of supply to the village population. This has been determined by collecting ground water samples and subjecting the samples to a comprehensive physio-chemical analysis. In order to determine the quality of the water for drinking water purpose, following parameters were considered: Potential of hydrogen (pH), Total dissolved solids (TDS), Alkanity, Total hardness, Chloride, Fluoride, Nitrate, Sulphate and Iron. The results have been compared with the drinking water standard prescribed by Bureau of Indian Standard (BIS). All the physiochemical parameters are within the prescribed limit except Total Hardness for Chippalturthy village and Ibrahimbad village. Regular monitoring of groundwater quality, abolishment of unhealthy waste disposal practices and introduction of modern techniques were highly recommended. The Study also indicates the usefulness of WQI in estimating the drinking water quality of the ground water.

The paper presents voltage restoration system is class of custom power device providing consistent distribution of power quality. It use series connected custom power apparatus which is aimed to defend sensitive loads from supply side distribution except for outage. Mainly we used UPS stabilizer to reduce voltage and the stabilizer will operate when the voltage is increased. So we designed dynamic voltage restorer that operates both condition like increase and decrease of voltage. So this is advantage and more accurate and also it is less costly then UPS and stabilizer. Due to installation of this system battery life can also be increased because when variation occurs in voltage supply from line will be continued from line and difference of voltage will be taken from battery. For example in UPS if input voltage is 180v, circuit will be trapped and entire load will be on battery that generate 50v AC inject to it with in phase, same way if output is 260v and generate 30v AC and inject it with out of phase signal in this way the output will be fixed at 230v AC this is advantageous and battery life will also increase.

Speed control of Induction motor drive is one of the major problem faced in almost all industries and leading sectors. In this paper a technique is implemented for a better speed control for induction motor drives using a multilevel inverter. Multilevel inverter have lower distortion of output voltages and Total Harmonic Distortion (THD) of machine currents under steady state operating conditions can be minimized. The switching angle for the pulse is selected to reduce the harmonic distortion. In this drive system it has advantages like reduced total harmonic distortion and higher torque. The model of the multilevel inverter system is fed with SVM method to control the induction motor. The simulations are performed using MATLAB/SIMULINK software and the results are presented.

Critical Role of Wettability Alteration in Improved Oil Recovery by Low-Salinity Water in Sandstone Rock - A Theoretical Approach

Pages: 134 - 143
Low Salinity Flooding (LSF) is an emerging technology to improve oil recovery for both sandstone and carbonate reservoirs. Low salinity water injections for oil recovery have shown seemingly promising results in the case of clay-bearing sandstones saturated with asphaltic crude oil. Testing over the last 20 years has shown that incremental oil recovery using this method can be potentially significant, with sandstone reservoirs showing an incremental oil recovery range of between 5% and 30% of original oil in place (OOIP).The underlying mechanisms behind this phenomenon is not well understood, but many researchers have suggested that it is related to complex crude oil/brine/rock interactions. In recent years, positive results have been presented regarding the combination of low salinity water and surfactant injection. The answer requires a thorough understanding of oil recovery mechanism of low salinity water injections. Numerous hypotheses have been proposed to explain the increased oil recovery using low salinity water, including migration of detached mixed-wet clay particles with absorbed residual oil drops, wettability alteration toward increased water-wetness, and emulsion formation. The mechanisms of enhanced recovery are considered to be decrease of residual oil saturation and alternation of rock wettability. In addition, the mobility control mechanism due to induced fines migration by low salinity water, and the consequent flux diversion is also a possible mechanism for enhanced recovery in low salinity water flooding. It has been suggested that low saline water flooding has a potential for improved oil recovery in all clayey sandstone formation containing crude oil. The result from different work indicates that the initial wetting condition is a crucial property for the effect of low salinity injection. It is obvious that the dominant mechanisms of low-salinity waterflooding are yet to be discovered. However, wettability is considered a key factor that affects fluid distribution in a porous medium. Therefore, the main objective of this paper is to provide theoretical understanding of the effect of brine salinity on rock-wettability alteration for a better understanding of low-salinity-water mechanisms. This paper also contains different effects, parameters and mechanisms which alters wettability of rock towards more water wet condition, which ultimately helps to enhance recovery from sandstone reservoir.

Agriculture is the basic occupation of all Indians. Farmer is said to be man of nation. We consider this as our responsibility to explore this occupation and take it to a higher level from technology point of view. The basic purpose for developing this system is crop disease prediction using various data mining techniques. Our project describes a new approach to crop disease prediction which helps to prevent future economical losses. This project emphasizes on every single concept related to crop diseases. This is accomplished by building a web platform in which farmers can interact with expert, share their experiences and knowledge. This results in a dynamically-growing online survey, which ultimately helps in data collection that can be used to identify various crop diseases and helps to prevent them. This portal can be used for multiple purposes where agro based industries can use our data to launch their products as well as acquire feedbacks. Agricultural institutes can explore new patterns in crop diseases and use required technology to prevent them. This system will be helpful for students perceiving agriculture studies; they can collect the correct information from the appropriate source and in precise manner.

Coconut cultivators and oil mill owners expressed a need for commercial and small equipment which can dry kernels irrespective of the weather conditions within the shortest time. Since, the conventional methods use natural convection and conduction to transfer heat with the help of burners or furnace setups, they devour a lot of time. Here, an infrared lamp is made use of as the primary heat source to heat the organic contents placed in a closed chamber so as to obtain the ambient conditions necessary to provide uniform and expedite desiccation. The model was designed using Solidworks 2016 and the structural and thermal analysis was done using the in built solver.

In a manual gear driven four wheeled automobile which climbing a positive gradient, it is difficult for the driver to throttle the vehicle after fully applying the brakes. This special situation involves the expertise of the driver as the full application is dependent on the reflex action of the driver. Many people may not possess this skill. To overcome this problem, a Self-Locking Wheel Mechanism is attached to the idle shaft to the axle. Ratchet and pawl is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. If the vehicle approaches a positive gradient, the gyro sensor send signal to the relay to energize the solenoid which engages the ratchet and pawl mechanism. The driver only needs to throttle the vehicle instead of adjusting clutch, handbrake and throttle simultaneously. The mechanism is automatic, hence when the system detects positive gradients, anti-roll back system is engaged and on reaching level roads, it automatically goes to off position. This mechanism relieves the driver from this hectic task and making his role simpler.

Pages: 166 - 173
This paper has been envisaged which consists of analysis and design of multi-storeyed building using steel concrete composites. The building is analysed by using Sap 2000 and designed according to codal provisions. Steel concrete composite means the concrete slab is connected to the steel beam with the help of shear connectors, so that they act as a single unit. Steel concrete composite construction is now a day’s very popular owing to their advantages over conventional concrete and steel structures. Concrete structure is bulky and imparts more seismic weight and less deflection whereas steel structure imparts more deflection and ductility to the structure, which is beneficial in resisting earthquake forces. In the present work a simplified method of composite slab, beam and composite column design is used and software is developed with pre and post processing facilities in Sap2000. The screenshots are included in the paper to illustrate the method employed for designing composite slab, beam and column.
