Cable stayed bridges are similar to the suspended bridge i.e. it has towers and a deck that is held by using cables, but its cables keep the deck through connecting it immediately to the towers as a substitute via suspender cables. It normally carries pedestrians, bicycles, cars, vans, and mild rail. It has more than one tower also called pylons, through which cables guide the bridge deck. A one-of-a-kind feature is the cables which run immediately from the tower to the deck, generally forming a fan-like pattern or a chain of parallel strains. That is in evaluation to the modern-day suspension bridge, wherein the cables assisting the deck are suspended vertically from the principle cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is most useful for spans longer than cantilever bridges and shorter than suspension bridges. However it is the range where cantilever bridges would develop heavier if the span has been lengthened; at the same time as suspension bridge cabling might not be more in economical aspect if the span had been shortened. In this study we are analysing a 500 m long cable stayed bridge with different cable or pylon type arrangement using analysis tool staad. In this research work we are analysing the loading conditions as per conventional (manual) method. Here it is concluded that with respect to the shape of tower we noticed that H shape pylon shows low amount of sag and moment in the cables and in the deck because it has more number of joints which are not uniform so that the concentration of stress and tension carrying capacity of the cables was not effectively distributed to the other parts of the cable which may lead to maximum concentration in some cables, when compared to circular which has homogeneous member.

The objective of this study is to find a better joint configuration which has more strength with minimum added weight. Hybrid joining is the principle of combining different joining technologies. Here, Mechanical fastener and adhesive are used together. Use of a mechanical fastener in hybrid joint is a fail-safe design, but it is an added weight to the structure. Because fastener did not contribute to tensile strength until the adhesive fails. Hence attachments are used to alternate the load paths to the fastener and utilizing the fastener to provide strength to the joint once the joint was loaded. Numerical analysis is carried out to optimize the added curve attachment on conventional hybrid lap joint. Hybrid lap joint with curve attachments of different load transfer angles are designed and analyzed to find a better joint configuration. The analysis results shows that the hybrid joint with the curve attachment of load transfer distance to height ratio of 4 (14 degree) provides the maximum load transfer to the fastener and has the higher strength than other lap joint configurations.

A single phase grid-connected converter is usually adopted in low power renewable systems. This paper deals with a review of the state of the art of multi level topologies and a theoretical power loss comparison with the proposed solution is compared. The proposed converter architecture is based on a full-bridge topology with two additional power switches and two diodes connected to the midpoint of the dc link. Since the two added levels are obtained by the discharge of the two capacitors of the dc link, the balancing of the midpoint voltage is obtained with a specific pulse width modulation (PWM) strategy, Multilevel converters have been under research and development for found successful industrial application. This is still a technology under development and many new contributions and new commercial topologies have been reported in the last few years advances made in modulation and control of multilevel converters are also addressed. A great part of this paper is devoted to show nontraditional applications powered by multilevel converters and how multilevel converters are becoming an enabling technology in many industrial sectors.

The Concrete is an engineering composite material made with cement, aggregates and admixtures in some cases. Due to the day by day innovative usages and developments in construction field, the world wide consumption of natural aggregate is very high and at the same time production of solid wastes from the demolitions and manufacturing units is also very high. Extensive use of concrete leads to the scarcity and unavailable of natural aggregate. Because of this reasons the reuse of demolished construction wastes and solid wastes from manufacturing came into the trend to reduce the solid wastes from demolition and manufacturing units and as well as to decrease the scarcity of natural basic aggregate. To overcome the issues many research were done to use many industrial waste as alternative material for concreting. In this project control concrete is casted for M25 grade and the partial replacement of concrete material were decided to reuse industrial waste such as blast furnace slag and ceramics tiles as coarse aggregate replacement in rage of 20%, 25%, 30% by weight of 20mm sieve size coarse aggregate.

Concrete is a composite construction material composed of aggregate, cement and water. There are many formulations that have varied properties. The aggregate is generally coarse gravel or crushed rocks such as lime stone or granite, along with a fine aggregate such as sand. The cement commonly Portland cement and other cementitious materials such fly ash and slag cement, serve as a binder for the aggregate. Various chemical admixtures are also added to achieve varied properties. Water is then mixed with this dry composite which enables it to be shaped and then solidified and hardened into rock-hard strength through a chemical process called hydration. The water reacts with the cement which bonds the other components together, eventually creating a robust stone-like material. Lime sludge is generated from paper, acetylene, sugar, fertilizer, sodium chromate, soda ash industries, and water softening plants. Approximately 4.5 million tons of sludge in total is generated annually from these industries. It is extracted by the precipitators in the smokestacks of coal-burning power plants to reduce pollution. About 120 coals based thermal power stations in India are producing about 112 million tonne per year. In the present study, concrete cubes have been cast by Partial replacement of cement with various percentage lime sludge. The method adopted in this investigation is as per the IS code specifications.

Renewable energy technologies gives us much cleaner, abundant energy gathered from self-renewing resources such as the sun, wind etc. Increase in power demand leads to increase in powerfailure. Hence, renewable energy sources acts as constant load provider. A converter topology for hybrid wind/photovoltaic energy system is proposed. In reality, combining both solar and wind power sources provides us with much needed power generation. By using Renewable energies we have getting advantages of nil fuel cost and environmental impacts got reduced. In this paper, we will see a SEPIC converter topology is used for the hybrid power sources. Two inputs, one from wind energy and another from solar PV panel are given to the converter and maximum power is extracted by using fuzzy logic maximum power point tracking method. Depending on the availability of the energy sources this configuration allows two sources to supply the load separately or simultaneously. The output is given to inverter which converts dc to ac and then applied load. This hybrid energy is given to the three phase inverter. It will convert that DC voltage into AC voltage. This AC voltage is given to the load. The sinusoidal PWM technique is applied to the inverter to control the output voltage and the Fuzzy controller compensates reactive power in the grid. Simulation is carried out in MATLAB/ SIMULINK. Here in this paper, we will prove that fuzzy based controller is best for controlling the production and supplying of power in the bus by comparing with other controllers namely PI, Hysrterisis.

The report presents theoretical studies and experimental investigation was carried out to improve the thermal performance of a domestic refrigerator with latent thermal storage system, highlighting the advantages of use of phase change material (PCM) associated with the evaporator. Phase change materials (PCM) are substances with high latent heat content that freeze and melt at a nearly constant temperature, accumulating or releasing large amounts of energy during the process. The desired working model of domestic refrigerator using (PCM) phase change material is successfully designed and fabricated. It is also successfully tested for working. With PCM, the air temperature is kept constant at 10°C for 12 hours, compared to without PCM where the air temperature rises continuously and rises above 10°C in just 1 hour. As the PCM melts, it absorbs the thermal load that enters the cold storage space, thus limiting the rise in the temperature and maintains a constant temperature inside the cabin during loss of electricity, which may occur due to an accidental power loss or done purposely to achieve electrical load shifting. The analysis of the experiment exemplifies the improvement of a conventional refrigeration system’s COP (Coefficient of performance) considerably.

In the field of Artificial Intelligence, on one hand, scientists have made many enhancements that helped a lot in the development of millions of smart devices. On the other hand, scientists brought a revolutionary change in the field of word processing and one of the biggest challenges in it is to identify the preceding words and actually suggest succeeding words that conform to semantic rules of the given language. One of the most widely used techniques for the validity of these types of document is Natural Language Processing. Natural Language Processing is a subfield of artificial intelligence concerned with the interactions between computers and human languages, in particular how computers process and analyze large amounts of natural language data. In this project we have based our word prediction on N-Grams model and have added the support of english grammar rules for improving the quality of the word prediction tools currently in use. By implementing separate rules for all the punctuation marks encountered in the English text we aim to improvise the word prediction at the granular level and thus as the end result obtain a sentence completion tool based purely on the limiting punctuation marks such as the "?" , "." or "!".
