Design of thermostatic expansion valve to increase COP of VCR system

The thermal expansion valve is used many vapor compression refrigeration systems such as refrigerator, air- conditioner etc. Hence many techniques have been investigated on thermal expansion valve to increase COP of VCR system. COP of thermal expansion valve can be increased either by controlling the bulb pressure or by decreasing compression work. This is an attempt to design expansion valve for increased COP with respect to mass flow control of refrigerant and the particular thermal parameter which are affecting to COP. The validation of design of thermal expansion valve is planned to validate by CFD analysis.

Evaluation of digital age transportation in Delhi-NCR

Change is coming to transportation, whether we’re ready for it or not. The Digital Age has begun, and technology has brought us open traffic data, the picture of alternative routes, GPRS, current network status and social customer service. As Digital age transportation will see a revolution over the next five years as transport operators adapt and new entrants arrive, new business models will transform the use of user information, payments, integration, and automation. This study will center around Intelligent Transportation System usage for to redesign benefit conveyance models and operational proficiency. Some measures should be taken by high power committee to decongest the roads of Delhi. The ultimate aim of the paper is that ITS could be put into implementation immediately. The plan was in four stages: background information, identification of problems, intervention, and monitoring. The possible solutions for problems encountered are suggested. This plan which was efficient and cost-effective can be used in transportation infrastructure in Delhi-NCR.

Modeling, analysis, and prototype of an involute spur gear

This project deals with the modeling and analysis of spur gear with an involute profile. The involute gear profile is the most commonly used system for gearing today. In an involute gear, the profiles of the teeth are involutes of a circle. In involute gear design contact between a pair of gear teeth occurs at a single instantaneous line. Rotation of the gears causes the location of this contact line to move across the respective tooth surfaces. The project mainly deals with modeling of spur gear with the help of CATIA, the analysis was done in the ANSYS software and prototype was done on the 3D Printer.The spur gear with involute profile was modeled with the help of CATIA. This model was imported into ANSYS with IGES file format for analysis. In this two types of analysis was done. One is model and the other is static analysis. All the results were tabulated. By using the features of CATIA, the model was saved in the form of .stl (stereolithography) for 3D Printing; the file was imported in QURA software. QURA will generate the g-code which was used to print the component in 3D.

Mechanical behaviour of hybrid composite filled with flax fiber

Fiber reinforced polymer composites has been used in a variety of application because of their many advantages such as the relatively low cost of production, easy to fabricate and superior strength compares to neat polymer resins. Reinforcement in the polymer is either synthetic or natural. Synthetic fiber such as glass, carbon etc. has high specific strength but their fields of application are limited due to the higher cost of production. Recently there is an increasing interest in natural fiber based composites due to their many advantages. In this connection, an investigation has been carried out to make better utilization of sisal fiber for making value-added products. The objective of the present research work is to study the physical, mechanical and water absorption behavior of flax fiber reinforced epoxy based hybrid composites. The effect of fiber loading and length on mechanical properties like tensile strength, flexural strength, the hardness of composites is studied. Also, the surface morphology of fractured surfaces after tensile testing is examined using scanning electron microscopy (SEM).

Review Paper

The inquisitive path for segmentation of mobile customers using data mining approach

In today’s world, data mining has increasingly become very interesting and popular in terms of all application. Telecommunication companies generate a tremendous amount of data. These data include call detail data, which describes the calls that traverse the telecommunication networks. Data is a very important ingredient and extracting knowledge from the data serves great purposes to the users.This work helps in identifying the activities Segmentation of mobile customers of different groups will be done based on some rules. The basic principles of data mining are to analyze the data from the different angle, categorize it and finally to summarize it. The need for data mining is that we have too much data, too much technology but don’t have useful information. Data mining software allows the user to analyze data. This paper introduces the key principle of data pre-processing, Segmentation, classification, clustering and introduction of WEKA tool.Weka is a data mining tool. It provides the facility to classify the data through various algorithms. Data mining is the process of analyzing data from different viewpoints and summarizing it into useful information. Data mining is one of the top research areas in recent days. WEKA is a data mining tool, it provides the facility to classify and cluster the data through machine learning algorithm.

Design and analysis of aircraft landing gear axle

The Aircraft Landing Gear supports the entire weight of the Aircraft during Landing and ground operations. They are attached to primary structural members of the aircraft. The type of gear depends on the aircraft design and its intended use. Most landing Gear have wheels to facilitate operation to and from hard surfaces, such as airport runways. Our project mainly aims in designing and analysis of Landing gear Axle for 1.25 tonne, SWIFT type, UAV (Unmanned Aerial Vehicle), this project was conducted under the guidance of DRDO (Defense Research and Development organization). Other Gear feature skids for this purpose, such as those found on Helicopters, Balloon gondolas and in the tail area of some tail dragger aircraft. In the design and analysis of landing gear axle, the wheels of the aircraft are attached to the bearings which are in turn attached to the axle, when in turn supports the entire wheel system and absorbs the impact while touching the ground. These are being designed according to FAR23 regulations. Aircrafts that operate to and from frozen lakes and snowy areas may be equipped with landing gear that have skid, aircrafts that operate to and from the surface of water have pontoon type landing gear. This landing gear axle can be used in all types of aircrafts regardless of the landing gear, shock absorbing equipment, brakes, retraction mechanism, control, warning devices, cowling, fairings Structural members used.
