Inconel 718 has vast range of aeronautical applications. The CNC end milling is the machining processes used for the production of high precision components of aircraft. The machining inconel 718 for high precision always leads to high power consumption and low productivity. This work deals with maximization of productivity and minimization of roughness simultaneously by Taguchi-Grey-Fuzzy logic in cutting of Incone1718 by end milling operation. The control factors considered are depth of cut, feed, speed and type of insert material with roughness and productivity (material removal rate) as responses. Here L18 orthogonal array is utilized as design of experiment with 3 levels of depth of cut, speed, feed and two levels of type of insert material. After the experimentation the optimum levels were obtained by the application of taguchi-grey-fuzzy method. Based on confirmation test, this technique gave 38% increment in multi response performance index (MRPI) which is the combined effect of all the three responses. Also, productivity and roughness increased by 37% and 61 %.

Solar energy is a renewable and clean source of energy and the easiest to utilize among all the other renewable resources available. Majority of the solar energy harnessing firms use panels made of a single junction solar cell for conversion of solar energy to electrical energy. With the advent of modern technology, multi-junction photovoltaic cells are made available. The multi-junction photovoltaic cells contain multiple P-N junctions within them. Due to these multiple junctions, heating of the cell is common which decreases the cell's efficiency. This is more prominent in certain concentrated photovoltaic systems and also may lead to permanent damage to the cell. The paper describes a cooling system design, which consists of a block on which the solar cell is to be mounted and water is made to flow in this block when the temperature of the cell exceeds beyond the maximum allowable temperature of the cell (60°C − 70°C), this temperature is measured by an infrared thermometer. The cooling system developed helps regulate the cell temperature and also assists in efficient working of the cell.

Today images and videos are everywhere. In fact, the sheer quantity of images on social media and networking sites is unfathomable. Every device is now fitted with a camera. This opens up huge possibilities. Object Recognition is a process of detecting an object and identifying it using various image algorithms. The main purpose of this paper is to recognize objects in real time and allot the objects to the classes that are previously defined. The algorithms that we utilized are more computationally efficient. Previously, object detection was done using RFID and IR technologies which required dedicated hardware. But with the advent of image processing and neural networks, we require almost no new hardware. Almost everything has camera these days from pens to mobile phones. This has given rise to a new field called computer vision i.e. using pictures and videos to detect, segregate and track objects or events so that we can “understand” a real world scenario.

The present study examines the possibility of using an ultrasonic guided wave technique for liquid level sensing. The setup consists of an Aluminium thin beam which is partly immersed in a liquid whose level is to be determined. When a wave guide is immersed in the liquid, guided wave in the waveguide is attenuated due to the leakage of its energy into the surrounding water. The amount of leakage is related to the characteristics of the waveguide and the surrounding liquid liquid. With these predictions, it is possible to relate the measured characteristics to the liquid level. Previous research shows that the various modes of Lamb waves are influenced by the surrounding liquid. Therefore, the change in the characteristic of Lamb waves can be used as a function of liquid level. This effect has also been investigated using Finite Element Analysis.

Wind turbine blades are huge structures, with complex design. Also, Blade is most complicated and costly component of a wind turbine. In present study mass of blade is reduced without increasing the stresses developed. For calculating aerodynamic loads acting on a blade of wind turbine BEM (Blade Element Momentum) theory is used. Tangential and Normal Aerodynamic loads are calculated for three different wind velocities i.e. 6, 8 and 10 m/s, In this study three dimensional modeling of blade is done using special wind turbine blade modeling software called Numerical Manufacturing and Design (NuMAD). The stresses developed at different critical points of turbine blade are obtained. The mass of turbine blade for different shear web configuration are also calculated. Using these values of stresses, optimal location of shear web is identified in MATLAB using genetic algorithm tool. The optimal locations of shear web are 55.18%, 55.84% and 55.27% and optimal mass of the blades are 2095.4 kg, 2105.1 kg and 2098.4 kg for the wind velocities of 6, 8 and 10 m/s respectively. The mass of the blade is reduced up to 1.02%.

In today's world the rate of differently abled people is increasing day by day. According to the CENSUS 2011 it is showed that out of all disabilities, 20% are facing disability in movement. Wheelchairs have been the basic and most widely used aid for such people. But there are people suffering with partial paralysis or quadriplegia which affect their limbs. Thus, they need another person in order to assist the movement of the chair. A smart wheelchair is the best option in this case. A smart wheelchair is a powered wheelchair to which computers, sensors, and assistive technology are attached. We are proposing a smart wheelchair in which we use a head gear with a Gyro sensor to detect the head movement and will generate signals accordingly to move the chair. When head tilts towards the left the chair will move in left direction and similarly in forward, backward and right direction according to the movement of the head with the help of motors powered by a battery thereby eliminating the need for another person. This prototype will help such people to get rid of all the joysticks and controls and provides a convenient and economical solution bringing a sense of independency into their lives. Necessary precautions will be incorporated to ensure the safety of the person.

In recent years, cloud computing has gained lots of importance and is being used in almost all applications in terms of various services. One of the most widely used service is storage as a service. Even though the stored data can be accessed from anytime and at any place, security of such data remains a prime concern of storage server as well as data owner. It may possible that the stored data can be altered or deleted. Therefore, it is essential to verify the correctness of data (auditing) and an agent termed as Third Party Auditor (TPA) can be utilised to do so. Existing auditing approaches have their own strengths and weakness. Hence, it is essential to propose auditing scheme which eliminates limitations of existing auditing mechanisms. Here we are proposing public auditing scheme which supports data dynamics as well as preserves privacy. Data owner, TPA, and cloud server are integral part of any auditing mechanism. Data in the form of various blocks are encoded, hashed, concatenated and then signature is calculated on it. This scheme also supports data dynamics in terms of addition, modification and deletion of data. TPA reads encoded data from cloud server and perform hashing, merging and signature calculation for checking correctness of data. In this paper, we have proposed efficient privacy preserving and dynamic public auditing by utilizing Merkle Hash Tree (MHT) for indexing of encoded data. It allows updating of data dynamically while preserving data integrity. It supports data dynamics operations like insert, modify and deletion. Several users can request for storage correctness simultaneously and it will be efficiently handled in the proposed scheme. It also minimizes the communication and computing cost. The proposed auditing scheme is experimented and results are evaluated considering various block size and file size parameters.
