Implementation of Photovoltaic Converter for Water Pumping System

Abstract

This paper proposes a new, low cost DC/DC converter and a inverter driving system for induction motor. The converter is designed to drive a Induction motor directly from Photovoltaic (PV) energy source. The Induction motor is better because of its low cost, reliability, low maintenance and high efficiency. DC output voltage from PV module is converted into AC and is stepped up using a transformer. The output of the transformer is rectified and is fed to a Voltage Source Inverter (VSI) to attain sufficient voltage to drive the motor. As the PV cell posses the nonlinear behavior, the Maximum Power Point Tracker (MPPT) controller is needed to improve the utilization efficiency of the converter. The MPPT algorithm proposed in this paper based on hill climbing algorithm, for matching the load and to boost the PV module output voltage. PI Controller is used to control the pulses and the controlled output is given to the Induction Motor. Here instead of water pump, we have used Induction motor for the ease of operation. The entire system is simulated using Matlab Simulink environment. The system is expected to be operated with high efficiency and low cost for long lifetime.

IMPROVEMENT OF POWER QUALITY IN WIND ENERGY SYSTEM USING STATCOM

Abstract

This paper presents improvement of power quality in wind energy system using STATCOM (Static compensator). The project study demonstrates the power quality problem due to installation of wind turbine with the grid. The power quality measurements are- the active power, reactive power, variation of voltage (sag, swell), flicker, harmonics and electrical behavior of switching operation. In this proposed scheme static compensator (STATCOM) is connected at a point of common coupling with a battery energy storage system (BESS) to mitigate the power quality issues. The main functional requirements of the STATCOM in this paper are to provide shunt compensation, operating in capacitive mode only, in terms of the following; voltage stability control in a power system, as to compensate the loss voltage along transmission. Here two control schemes for STATCOM are compared: Bang-Bang current controller and Fuzzy logic controller. In this paper its operation and its simulation diagram is discussed. The STATCOM control scheme for the grid connected wind energy generation system for power quality improvement is simulated using MATLAB/SIMULINK in power system bock set.

Adsorption and Removal of Zinc (II) from Aqueous Solution Using Peepal (Ficus religiosa) Leaf Derived Carbon

Abstract

The present work is an attempt to determine the feasibility and reliability of Peepal (Ficus religiosa) Leaf Derived Carbon utilized as an adsorbent for the removal of zinc (II) from aqueous solution. The effects of solution pH, adsorbent dose, temperature, initial metal ionconcentration and contact time on the adsorption process with respect to the zinc (II) removal were investigated. The optimum conditions obtained were 30 min contact time, 0.8g adsorbent dose, 45 0C, 0.12M Zn and pH 7 for zinc removal. Experimental equilibrium data were analyzed by the Langmuir and Freundlich isotherm models. The results obtained from the experimental work showed that biomass carbon derived from peepal leaves are transformed into adsorbent for removing metal ions from the aqueous solution. Peepal leaf carbon show promising results in removing zinc (II) from aqueoussolution, thus this material could be used as low cost adsorbent to replace the expensive commercial activated carbon during adsorption process.

Enhanced Z-Source Inverter with Capacitor Voltage Stress and Soft-Start Capability

Abstract

This paper proposes an improved Z-source inverter topology. Compared to the traditional Z-source inverter, it can reduce the Z-source capacitor voltage stress significantly to perform the same voltage boost, and has inherent limitation to inrush current at startup. The control strategy of the proposed Z-source inverter is exactly the same as the traditional one, so all the existing control strategy can be used directly. A soft-start strategy is also proposed to suppress the inrush surge and the resonance of Z-source capacitors and inductors. The operation principle of the proposed topology and comparison with the traditional topology are analyzed in detail. Simulation and experimental results are given to demonstrate the new features of the improved topology.

Automatic Underground Car Parking System

Abstract

As a town modernization progress, the number of vehicles increases accordingly. Drivers generally need to spend a major amount of time searching the blocks around their destination searching and in the offing for available parking spaces. To overcome above difficulty there is need of an advanced car parking system. Metropolitan cities strongly need advanced parking systems, providing drivers with parking information. Existing parking systems usually ignore the parking price factor and do not automatically provide optimal car parks matching drivers’ demand. Currently, the parking price has no negotiable space; consumers lose their bargaining position to obtain better and cheaper parking. Multi-store car parking is growing popular as they enable to conserve space. However parking on multiple floors brings its own challenges such as need of using lift mechanism for moving the vehicle from one floor to another, coordination between the vehicle and the lift mechanism, co-ordination between parking and un-parking of vehicle etc. The aim of this paper is to identify the issues and challenges in development of such a system by implementing a prototype using Firebird IV as automated self-parking vehicles.

Investigation of EDM hole drilling

Abstract

This paper presents an investigation of holes drilling using electrical discharge machining (EDM) on SKD 11, difficult to machine conventionally. EDM is a thermal machining process that utilizes spark discharges to erode a conductive material. In the present study, attempt is made to find the optimal machining conditions with metal removal rate (MRR) and electrode wear rate (EWR) as objective. It was observed that with increase in discharge energy MRR and EWR increases. Response surface methodologies D optimality test was used to determine the optimal machining parameters, among which the discharge current and the pulse on time are found to be the most significant. The obtained optimal machining conditions are current of 6 A, voltage of 28.68 V and a pulse-on time of 25.84 µs. It was observed that MRR mainly depend on discharge energy while longer pulses increases EWR.

AGV Path Planning Using Dijkstra’s Routing Algorithm

Abstract

Automated guided vehicles (AGVs) are widely used in container terminals for the movement of material from shipping to the yard area and vice versa. Research in this area is directed toward the development of a path layout design and routing algorithms for container movement. The problem is to design a path layout and a routing algorithm that will route the AGVs along the bi-directional path so that the distance traveled will be minimized. This thesis presents a bi-directional path flow layout and a routing algorithm that guarantee conflict-free, shortest time routes for AGVs. Based on the path layout, a routing algorithm and sufficient, but necessary conditions, mathematical relationships are developed among certain key parameters of vehicle and path. A high degree of concurrency is achieved in the vehicle movement. The routing efficiency is analyzed in terms of the distance traveled and the time required for AGVs to complete all pickup and drop-off jobs. Numerical results are presented to compare performance of the proposed model. The research provides the foundation for a bi-directional path layout design and routing algorithms that will aid the designer to develop complicated path layouts.

EFFECT OF SIZE OF AGGREGATE ON SELF COMPACTING CONCRETE OF M70 GRADE

Abstract

concrete is a versatile widely used construction material. Ever since concrete has been accepted as a material for construction, researchers have been trying to improve its quality and enhance its performance. Recent changes in construction industry demand improved durability of structures. There is a methodological shift in the concrete design from a strength based concept to a performance based design. At present there is a large emphasis on performance aspect of concrete. One such thought has lead to the development of Self Compacting Concrete (SCC). It is considered as “the most revolutionary development in concrete construction”. SCC is a new kind of High Performance Concrete (HPC) with excellent deformability and segregation resistance. It can flow through and fill the gaps of reinforcement and corners of moulds without any need for vibration and compaction during the placing process. The guiding principle behind self-compaction is that “the sedimentation velocity of a particle is inversely proportional to the viscosity of the floating medium in which the particle exists”. The other features of mix proportion of SCC include low water to cementitious material ratio, high volume of powder, high paste to aggregate ratio and less amount of coarse aggregate. One of the popularly employed techniques to produce Self Compacting Concrete is to use fine materials like Fly Ash, GGBFS etc.; in concrete, besides cement, the idea being to increase powder content or fines in concrete. The present investigation is aimed at developing high strength Self Compacting Concrete of M70 Grade. The parameters of study include grade of concrete and effect of size of aggregate. The existing Nan Su [2001] method of mix design was based on packing factor for a particular grade of concrete, obtained on the basis of experimental investigation. SCC characteristics such as flowability, passing ability and segregation resistance have been verified using slump flow, L box and V funnel tests.

Privacy-Preserving System for shared Data in the Cloud Environment by using Public Auditing Scheme

Abstract

The Cloud computing is the internet based computing it enables sharing of services. It allows user to use application without installation of any application and user can access their personal files and application at any computer with internet or intranet access. However, public auditing for such shared data, while preserving identity privacy, remains to be an open challenge. Current system proposed the first privacy-preserving mechanism that allows public auditing on shared data stored in the cloud. In particular, proposed work exploit ring signatures to compute the verification information needed to audit the integrity of shared data. With current system mechanism, the identity of the signer on each block in shared data is kept private from a third party auditor (TPA), who is still able to verify the integrity of shared data without retrieving the entire file and also provide the confidentiality to the shared data in cloud. Keywords: Cloud Computing, Privacy-Preserving, Data Security, Data Integrity.

REVIEW ON CHANGING THE MATERIAL OF A DIESEL ENGINE CATALYTIC CONVERTER TO REDUCE EXHAUST EMISSIONS

Abstract

In automobile industry, the exhaust from the internal combustion engine is a complex mixture of gases and fine particles. Many pollutants are introduced in the environment such as Carbon Monoxide (CO), Nitrogen Oxides (NOx), Hydrocarbons (HC), etc. These pollutants may lead to affect the respiratory system as well as increase the risk of heart problems, premature death and lung cancer. To control the emission of these pollutants in environment catalytic converters are used. The commonly used catalyst in converters is mostly a precious metal such as Palladium, Palladium and Rhodium. Platinum is widely used and very active catalyst, but is very expensive. Rhodium is used as reduction catalyst, while Palladium is used as oxidation catalyst. Since, these materials are expensive the cost of catalytic converter increases. Thus the purpose of the project is to improve effectiveness of catalytic converter by using a different material along with the regular used noble metals. These materials perform the same task along with the catalyst and the additional task of storing and releasing oxygen during rich mixture combustion.

It attempts to quantify intuitive qualities described by terms such as rough, smooth, silky, or bumpy as a function of the spatial variation in pixel intensities. In classification, template will be compared to a stored template in a database and then it will determine authenticated user. Keywords : Biometric, Iris, hybrid feature extraction, classification.

Effect of different Wool Scouring Techniques on Physical Properties of Wool Fiber

Abstract

The first process of preparing wool is termed scouring; wool scouring is the process of washing wool in hot water and detergent to remove the non-wool contaminants and then drying it. A growing concern for the environment has led to increased demands on the scouring process as reduction in pollution has become increasingly important as the pollution load associated with conventional emulsion scouring of greasy wool is extremely high. The work done by using Cow Urine (Gomutra) as natural ecofriendly scouring agent, has changed the concept of scouring from chemical and pollution oriented one, to a chemical free, eco friendly process with other advantages. In this research cow urine was used as alkali medium with an optimized value of 150 gpl along with natural detergent SapindusSaponaria (Reetha) of 20 gpl, in five bowl system with the help of ultra sound technology for process intensification. An attempt is made of wool scouring of raw greasy wool in dry state at very low temperature in an eco-friendly manner. The dry scouring process, unlike aqueous scouring, doesn’t adversely affect the intrinsic properties of wool fibers like strength, elongation, colour, moisture regain, etc. On the contrary, the whiteness index of dry scoured wool fibers was found to be better than convention detergent and alkali based aqueous scouring process. It was observed that using this optimized recipe effluent load was reduced by 40%, without hampering the other desired mechanical properties of Wool. Also this process doesn’t hamper the dyeing property of wool.

AERODYNAMIC ANALYSIS OF EAGLE WINGLETS ON AIRCRAFT

Abstract

In aeronautical engineering, drag reduction constitutes a challenge and there is room for improvement and innovative developments. The drag breakdown of a typical transport aircraft shows that the lift-induced drag can amount to as much as 40% of the total drag at cruise conditions and 80 to 90% of the total drag in take-off configuration. One way of reducing lift-induced drag is by using wingtip devices. By the implementation of “BIOMIMETIC ABSTRACTION” of the principle behind a bird’s wingtip feathers, we study about “TIP SAILS” at the aircraft wingtip. The numerical investigation of such a wingtip device is described and preliminary indication of its aerodynamic performance is provided. The model of our wing is designed and analyzed using ANSYS.

Implementation Of OLAP Semantic Web Technologies For Business Analytic System Development

Abstract

Business Intelligence (BI) tools provide fundamental supporting analyzing large volumes of information. Data Warehouses (DW) and Online Analytical Processing (OLAP) tools are used to store and analyze data. Nowadays more and more information is available on the Web in the form of Resource Description Framework (RDF) and BI tools have huge potential of achieving better results by integrating real-time data from web sources into the analysis process. We describe the convergence of some of the most influential technologies in the last few years, namely data warehousing (DW), on-line analytical processing (OLAP), and the Semantic Web (SW). OLAP is used by enterprises to derive important business-critical knowledge from data inside the company. When using external data, an important issue knows the precise semantics of the data. Here, SW technologies come to the rescue, as they allow semantics (ranging from very simple to very complex) to be specified for web-available resources. Next, we go on to survey the use of SW Technologies for data modeling and data provisioning, including semantic data annotation and semantic-aware extract, transform, and load (ETL) processes. Finally, all the findings are discussed and a number of directions for future research are outlined, including SW support for intelligent MD querying, using SW technologies for providing context to data warehouses, and scalability issues.
