Resolution performances of remote sensing satellites is increasing, while allowed frequency band for data transmission is fixed as a design recommendation. Satellite to ground station link became a bottleneck and it's requested to overcame that limit. This paper presents a new flexible modulation scheme for a high-speed communication system with a high spectral efficiency (up to 24 bit/s/Hz) with...
Active ECUs (Electronic Control Unit) in a hybrid car while it is charging leads to inefficient power usage and reduction in ECU lifetime. To solve this issue, AUTOSAR has suggested PN (partial networking). As per the AUTOSAR specification, ECUs which are not required to be kept active during battery charging must be shutdown. This project's aim is to analyze the robustness of the design suggested...
This paper proposes an area efficient and low power Reed-Solomon (RS) decoder. The proposed decoder is designed using eight stage arithmetic pipelined architecture. The pipelined architecture of RS decoder performs the detection of error locator from the input stream and computes the error magnitude polynomial using the Berleykamp Massey's algorithm. The evaluation of error locator and computation...
Every nation dreams for highly efficient and economical type of energy production units. The scenario of power sector is inversely proportional as far as the generation and demand of power is concern. In India, normally the power plants run on the availability of fuel and consumers. Majority of the power generation units are fuel based in Indian power sector. There are so many types of fuel but coal...
The paper presented analysis the effect of direct coupling on metamaterial based resonators. Split ring resonator (SRR) and Open loop resonator (OLR) offering band stop characteristics are studied using Keysight ADS. The resonator parameters are optimized for performance a 2.45 GHz Wi-Fi band enabling it for Wireless communication applications. The paper also furnishes design equations for the proposed...
Micromirrors are used in numerous applications such as optical switching, projection displays, biomedical imaging and adaptive optics. In this paper, eigen frequency and Q-factor analysis of a piezoelectrically actuated micromirror is performed. The mirror structure consists of an Aluminium mirror plate and cantilever on each side of the plate for piezoelectric actuation. Q-factor analysis is done...
Today Cyber-attacks are increasing and the security technologies so far we used are in capable of handling the large data sets of data. Now a day the attacks motive has changed from simple hacking, damaging to large scale network and server system. In the presence of fresh and formerly unknown activities, intrusion detection rate is inaccurate and low. Many research works are focused in this area...
This paper presents the concept of image compression after encryption and study about the various technologies applied on encryption-then-compression technology. It is also analyses the various secured compression technologies and can be applied to different types of images. This survey addresses the recipe for the secured image compression technologies based on JPEG, JPEG2000 and JPEG XR and presents...
Composites play a major role in manufacturing firms due to its less weight and good strength. Development of metal matrix composite draws the application of the fabrication of aircraft and aerospace structures. Hence manufacturing of composites needs attention. This paper discusses an investigation of developing Adaptive Neuro Fuzzy Inference System (ANFIS) neuro fuzzy model to predict wear rate for...
Conservation and use of energy in an efficient manner is the fundamental goal of energy management. 78% of generated energy is used in the industrial area. The main aspect of energy conservation is to use the energy in an efficient manner. This paper presents the review on type of audit conducted in the industries and detailed energy audit in the aluminium industry. The audit processed through walk...
This paper introduces a low cost receiver for wind velocity measurement using FPGA with multiple ultrasonic transceivers. Wind speed is derived from the time taken by ultrasonic sound to travel between an ultrasonic transmitter and receiver. The receiver section of ultrasonic anemometer acquires the data for time of flight calculation from transmitter section and wind velocity is calculated. Ultrasonic...
Friction Stir welding has been used in the areas of marine, aircraft, space and food processing industries for decades because of low welding cost, nonformation of cracks and pores, good bonding due to low heat. Friction Stir welding parameters play a key role in determining the quality of the weld. Relating weld parameters to the quality of the finished weld is a challenging problem faced by today's...
This paper is an enhanced application based on history of records. It has been developed for privacy aware cross cloud service composition for processing big data applications. It can be effectively promotes cross cloud service composition in the situation where a cloud refuses to disclose all details of its service transaction records for business privacy issues in cross-cloud scenario. Our composition...
The justification of choice and reliability of primary converters (sensors) for use in emerging test-and-measurement and control systems for production equipment (direct heating of liquid reagents blocks) has been accomplished. A review of suitable primary converters available in the market has been provided, as well as comparison of the technical characteristics, taking into account the application...
In this paper, we propose a new variable decision strategy for solving SAT problems based on literal weights. The new algorithm makes use of the information from the structure of SAT problems into literal weights. We first consider the short clause can be satisfied, and select the literal of the largest literal weights is assigned. A new operator of literal Weights is designed to prevent conflicting...
This paper describes the selection of brushless motors, propellers and battery for getting maximum time of hover for a quadrotor UAV. We also introduce a experimental testbed to measure various parameters of the system like torque, thrust, RPM, current and voltage. The static testbed is directly interfaced through MATLAB for real time data acquisition. We tested different motor and propeller combinations...
There are so many methods used for segmenting the human brain images. The physician are following the invasive method to identify cancer which gives more painful to the patients. CT (computer tomography) scan, MRI (medical reasoning imaging) and CAD (computer aided design) are helpful to analyzing the abnormalities of different parts. For example the Tumor cells, cancer cells and the fractures in...
Pulse oximeter employed in intensive care units and is a crucial equipment employed to measure the vital parameters like heart rate and blood oxygen saturation levels. Using Pulse oximeter, photoplethysmographic (PPG) data is recorded using the PPG sensors attached to the patient is used to estimate oxygen saturation levels. Patient movements while recording the PPG data may result in erroneous estimation...
The accelerometer based on MEMS is the fast developing device which finds its application in MEMS. It finds its applications in different fields namely automobile, consumer electronics, aeronautical, biomedical and robotics applications. In all these applications the device works based on the principle that the displacement of a small proof mass etched into the silicon surface of the integrated circuit...
The purpose of this paper is to present a brief comparison between a conventional hexacopter and a cant angle hexacopter. A conventional hexacopter has got all its 6 rotors fixed and thrusted upwards in the body frame which gives it a decoupled 4 DOF motion or a coupled 6 DOF motion. But a cant angle hexacopter has all its six rotors canted at an angle tangentially to the radius of the frame. It provides...
