Effect of Process Parameters on Tensile Strength and Hardness Testing of Friction Stir Welding Joint of Aluminium Alloys with Different Tool Pin Profile
In this project, CNC Milling Machine is used to weld the parts together. The parts being welded are made up of dissimilar materials aluminium alloy AA5086 H32-AA6061 T6. The rotational speed is varied from 900 rpm to 1500 rpm while the welding speed is varied from 20 to 40 mm/min. The other parameter involved is the tool profile. The dimensions of the parts are (300mmx30mmx5mm) which are welded to form a butt joint. The effect of different tool pin profiles on the quality of the welded joint is also studied for welding. Different tool pin profiles considered are round threaded, circular/round and square. The tools are designed using Pro/E and are manufactured on a Lathe machine. After the parts are welded, various practical tests are performed on the welded parts that include the tensile strength and the Vickers’s hardness test. The experimental results proved that the highest tensile strength of the welded joint i.e., 28.65 N/mm2 was achieved with the square tool profile at speed 1200 rpm with feed 40 mm/min and the highest hardness value of 58 HV was achieved with the round tool profile at 1500 rpm and feed of 40 mm/min.

Study of Recycled Aggregate Concrete Containing Silica Fume as Partial Replacement for Cement
Recycle Aggregate Concrete (RCA) is the concrete product produced with recycled aggregate to replace part or whole of natural aggregate. The purpose of this study is to find the properties of RCA and compare the same with the concrete produced with natural aggregates2 Recycle Concrete Aggregate has also been described as “the most revolutionary development in concrete construction for several decades”. It has proved to be beneficial from the point of economic, environmental benefits and Preservation of non renewable recourses This thesis presents a study conducted on mechanical and durability properties of recycled aggregates concrete. The investigation covered concrete mixes at water cementitious material with ratio of 0.4. Ordinary Portland Cement of 43-grade was used in this study. The percentage of recycled aggregates that partially replaced natural aggregates by weight were 0%, 10%, 20%, 30%, 40% and 50%. Concrete cubes and cylinders were casted and tested in laboratories. The optimum proportion of replacement was found by conducting tests on mechanical properties like Compressive strength test and Split tensile strength test. The results show that the optimum replacement of recycled aggregates with natural aggregates was 30%. Up to 30% replacement, it is possible to gain the same strength as conventional concrete. Beyond 30% replacement the strength results following decreasing trend

An Efficient Community Question Answer (CQA) using the Metadata Rating
Community Question Answering (CQA) is the question answering process. Question Answering (QA) is the field of information retrieval and Natural language Processing (NLP). In this paper we mainly focus on lexical gap and word embedding problem. Here, the CQA aims to find the existing question which is equivalent to queried question. The other existing system of this paper is two novel category powered models. That is basic category powered model called as MB-NET and enhanced category powered model called as ME-NET. They are used to learn about the lexical gap and word embedding problem. The proposed system of this paper is to extend the metadata information easily using user ratings, like signals and Poll and Survey signals, into the learning process to obtain more powerful word representations.

Automatic Smart Parking System using Mobile Application
Internet of Things (IOT) plays a vital role in connecting the surrounding environmental things to the network and made easy to access those uninternet things from any remote location. It’s inevitable for the people to update with the growing technology. And generally people are facing problems on parking vehicles in parking slots in a city. In this study we design a Smart Parking System (SPS) which enables the user to find the nearest parking area and gives availability of parking slots in that respective parking area with the help of android app and it mainly focuses on reducing the time in finding the parking lots and also it avoids the unnecessary travelling through filled parking lots in a parking area by making use of sensor which continuously detects the parking slots and with the help of android app user comes to know the status of the parking area. Thus it reduces the fuel consumption which is eco-friendly and in turn reduces carbon footprints in an atmosphere.

Strength and Deformation Behavior of Concrete Made with Recycled Concrete Aggregates
With the development and modernization of societies, lot of construction activities are seen everywhere. These construction activities are increasing at faster rate by large amount. Also, the destruction of existing structures, which have reached their service life, runs parallel to the construction activities. It is not essential that the structures need to be demolished only after when they have completed their service life, but also due to change in fashion and ongoing trend of reconstruction of even healthy structures just for creating more space in order to meet the present demand. All such activities are generating waste in bulk, and this waste is called the Construction and Demolition (C&D) waste. Disposal of such C&D waste in a sustainable manner is a hard nut to crack for the builders, developers and owners. While the disposal of C&D waste is a challenge, on the other hand there is a severe shortage of naturally available aggregates for construction of structures. Reduction of this demand in a small way is possible with the recycling or reusing of construction and demolition waste generated from the construction activities. Hence, the recycling of demolished waste is a sustainable solution of C& D waste. Recycled concrete aggregate have limited application as fill and sub grade material below foundation of structures, pavement etc. these applications are non-structural applications. However research has been ongoing all over the world especially in Japan, China, European countries and some part of India also, from last 50 year in order to find the potential implement of recycled aggregates as a structural grade concrete. The research work on “Strength and Deformation Characteristics of Fiber Reinforced Concrete made with RAC” is presented here and is one such attempt to establish the RAC as a structural grade concrete. This research work focus on mainly four structural properties of concrete i.e. Compressive Strength, Split Tensile Strength, Flexural performance and Flexural toughness. In this present study the experimental part is divided into two different series viz. Series-A (without fibers concrete mix) and Series-B (1% by volume Steel fibers in concrete mix). The natural coarse aggregates are replaced with Recycled coarse aggregates at different replacement ratios. Four replacement ratios are considered in this present study 0% (control specimens), 20%, 40% and 80% M-20 grade of concrete mix is considered in this study. In order to predict the flexural performance of RAC, 16 reinforced concrete beam specimens were prepared. The section was designed as under-reinforced section and tested on UTM for flexural behaviour under two point loading. Based on the results obtained it is found that on addition of steel fibers there is increase in almost all the structural properties of normal concrete and concrete made with recycled aggregates. The investigation indicated encouraging results for RAC beams, cube and cylindrical specimens in all respect, thus pointing to recycled aggregate concrete as potential alternative structural grade concrete of the 21st century

Design and Fabrication of Automatic Trash Removal Machine
In this project the proposal concept is to replace the manual work in drainage cleaning by automated system. We know that water has a great importance in human being life, the water flow in drain full of wastes like polythene, bottles etc. The drains get blocked due to these wastes in water. Drainage are using for the disposal and unfortunately sometimes there may be loss of human life while cleaning the blockage in the drainages. To overcome this problem and to save the human life we implement design “Trash Removal System”. We designed our project to use this in efficient way to control the disposal of wastages and with regular filtration of wastages. This machine also uses battery for power supply and is locomotive system.
