Perpetual Motion Hydroelectric Generators is a system which generates electricity by using the potential energy of falling water under two circumstances, firstly for power generation and secondly for recirculation of water. These types of systems can be extremely useful in rural regions where there is a shortage of electricity as well as a limited supply of water. This paper describes the design and fabrication of a hydroelectric generator as well as a hydraulic ram pump. Emphasis is given to the calculation of power produced, discharge and the efficiency of the ram pump. The results obtained are validated with respect to standard fluid mechanics calculations.

The ability to make a product more desirable to consumers than competition is central to the success of every competitive business. The web application allows the user to see products and their functionalities together with the potential to comment on the product and can also show other customers ' comments. A potential customer finds it difficult to read and determine from the broad comments. The competition of two items based upon market segments that both can cover is determined by this approach. A "CMiner" algorithm is provided to find the top competitors for a particular item to predict competition using the customer reviews. This system returns the competitors of products correctly and reliably, as compared to previous models based on subjective and comparative Web expressions. Business organizations are not only able to identify competitiveness, but they are also able to benefit from meeting user needs.

This paper deals with the Defect reduction (DPU-Defect per unit) of MDT (Medium Duty Trucks) all over CIW (Cab-In-White) for increase in production rate and reduction in rework with subtraction of repeated concerns. Quality and performance of a Product is the one that weighs the OEM’s name, Bharath Benz was never the less in this area as Benz is named for its unique magic in makes. Basically Two Trucks are produced in CIW (Cab in White) – Heavy Duty Truck (HDT) & Medium Duty Truck (MDT). 60% of the HDT are made by Robots were as the MDT is of 20%, here starts the Difference in Production rate and quality issues which automatically degrades the Fame of the company. Keeping each and every concern in mind the main aim of the project is sketched in a way to increase the production to maximum and eliminate the defects to minimum. The Quality circle is implemented in the department and some of the results are picturized in this journal.

Polymer composites materials are those that don't seem to be degradable by naturally. These material can remain in earth for thousands of years. This leads to the accumulation of pollution to the environment. To address this problem, compound composites are packed with fibre, fillers and resins that are considered as natural sources arebio degradable. Among the assorted natural fibers, fibre fiber are targeted for its before and when pretreatment conditions to getting excellent fiber. In antecedent several researchers have founds varied fibers has been pretreated and that they get its properties and its applications. In this research, fiber is analyzed before and during pre-treating. The assorted pretreatment that appropriate for fiber are dispensed. Fiber is employed as reinforcement, Rice husk is employed as a filler materials and synthetic resin is employed as a matrix to fabricate composites by compression moulding ways and therefore the sensible board are fabricated. The fabricated sensible board are subjected to analyses by mechanical properties. The effects of pretreatment of fiber before and when pretreatment are determined and noted to study the investigation results. The obtained results are compared and therefore the best pretreatment are hand-picked on the idea of the properties of the fiber.

Traffic signal poles play a role of mitigating traffic congestions in cities. It slender structure which is usually characteristics with high deformation. It is exposed to load, various environmental factor and natural hazards. The aspiration of modal analysis in structure mechanics is to negotiate the natural frequency of an object or structure in times of free vibration. Conventional poles are replaced with I and T section by applying various material such as structural steel (SS), stainless steel (STS) and grey cast iron (CI). By predicting the ultimate section with low deformation. The ultimate material is endowed and fracture behaviour is prompt, substitute crack is inserted in the maximum stress spot and life cycle of the ultimate material section is deliberate.

GTAW (Gas Tungsten Arc Welding) or TIG (Tungsten Inert Gas) Welding is one of prime welding process which plays a vital role in most of the fabrication industries to weld various metals grades with various parameters. This TIG welding is most preferred because of the better joint which is produced during the process. Recent days new hybrid TIG like pulsed TIG, pulsed synergic TIG etc, comes into practice based on the applications. These TIG Welding variations comes into play because it increases the quality of weld furthermore by changing the various parameters like background current, voltage and control the heat that is generated over the process. In this paper, Pulse TIG is discussed to create an overall idea.

In the present world it is essential to find an alternate fuel source due to the increased industrialization and depletion in natural resources. The method of obtaining biodiesel from various sources and blending them with diesel is adopted in many economically developed and developing countries around the world. This paper investigates the utilization of Pongamia Pinnata Methyl Ester (PPME) blends with diesel in CI engine. The performance and emission characteristics of pongamia with diesel with B40 could substitute in the place of pure diesel and be used as an alternate source of fuel in the near future, thus saving the natural resources for the future generation. Performance parameter like brake thermal efficiency, specific fuel consumption, mechanical efficiency, brake power is evaluated.

This paper introduces an efficient hardware architecture for reconfigurable multiple constant multiplication block, based upon canonical signed digit (CSD)-based 4-bit vertical and 8-bit horizontal common sub expression elimination algorithm. The proposed architecture reduces the necessary number of full adder cells and the adder depths in addition to 4-bit specific sub-expressions (CS) in the vertical direction as well as 8-bit CSs in the horizontal direction, leading to reduces operation of adder blocks in comparison with 2-bit and 3-b binary CS elimination. In the first stage conversion of binary coefficients to canonical-signed digit reduce the adder path by lowering non-zero terms present in each coefficient. Further application of MODIFIED CSD conversion algorithm reduces the complexity in multiplicative block by identifying and eliminating the common sub expression leads to decrease in propagation delay with increase in performance of the system.

This paper deals with the design and simulation analysis of the hybrid solar vehicle under static conditions. The solar hybrid vehicle is effective in our everyday lives because many people have petrol cars and the emissions and fuel cost is now a serious problem. In addition to controlling vehicles pollution in the city, reduced fuel consumption and hybrid solar car use is used in vehicles to effectively reduce global warming and the environmental challenge in large-scale applications. In the last ten years, research has taken place on a large quantity of solar, hybrid solar and electrically operated cars, which is originating from several independent developments that all resulted in the idea of hybrid solar car and electric operated car. A hybrid solar vehicle was successfully designed, analyzed and fabricated at the end of this research.
