Abstract: The main objective of this study is to determine the factors influencing cloud computing adoption by Small and Medium-sized Enterprises (SMEs). Based on two dominant theories in the field of diffusion of innovation, a conceptual model is proposed. In order to test the model empirically, an online survey was designed and launched. Decision makers of 101 SMEs agreed to participate in this survey. In order to evaluate the internal, convergent, and discriminant validity of the instrument, factor analysis and reliability tests were performed. Logistic regression is employed to test our hypotheses. The results of regression reveal that decision maker’s knowledge about cloud computing is the main influential factor in decision making about its adoption.

Abstract

Efficient Energy Allocation Method for Symmetrical Relay Communication in Cooperative Mode

Vivek K.Dethe, Om Prakash, C.V.Ghule

DOI: 10.17148/IJIREEICE.2019.7102

Abstract: Most of the wireless devices (i.e. mobile handsets, laptops, tablets etc.) are designed with only one antenna, especially due to hardware limitations, size and cost factors; cooperative communication can be used to generate transmit diversity [1]. This enables single antenna wireless devices to share their resources during communication in such a manner that creates a Virtual MIMO (Multiple-Input and Multiple-Output) system [2-3]. Major challenges are Resource sharing, Communication Strategies, Energy Efficiency, Range and Security [4-5]. This paper considers the problem of how efficiently to allocate transmission energy in a wireless communication system with two delay- constrained cooperating sources and one destination. The sources in the system are assumed to cooperate via the Orthogonal Amplify-and-Forward (OAF) protocol. The channels are assumed to be flat fading and the sources are each required to satisfy an outage probability constraint. The analysis focuses on optimum energy allocation and energy efficiency for different channel state information under different set of assumptions.

Analysis of Brittle Fracture of Composite Insulators by using Finite Element Technique

Nagaraj.H.P, K N Ravi, N.Vasudev

DOI: 10.17148/IJIREEICE.2019.7103

Abstract: The Brittle fracture process causes cracks on the FRP rod of the Composite (Composite) insulator that leads to premature failure of Composite insulators. Major types of stress affecting the service life of an insulator are electrical, mechanical and environmental stress whereas the major physical threat is vandalism. For various transmission and sub-transmission voltages, the insulators are required withstand the maximum tensile strength of the conductor. Therefore, understanding the mechanical stress withstanding capability of Composite insulator is important. Proper designing of the strength of FRP (Fibre Reinforced Plastic) rod is most important. FEA (Finite Element Analysis) analysis of voltage distribution along the length of the Composite insulator is also necessary for the understanding of electric field stress required for surface deterioration of Composite insulator. The mechanical stress analysis for various cross sections of FRP rods for a given mechanical load has to be carried out in order to optimize the diameter of the FRP rod for better reliability. FRP rods of different diameter were considered, it is observed that when diameter is increased the maximum stress is reduced and hence, by increasing the diameter of FRP road better results can be obtained. It is also observed that displacement is more in FRP rod of lower diameter.

V.R Moganaa, Mrs A. Vijayadevi, V. Priethee, A. Vaishnavi

DOI: 10.17148/IJIREEICE.2019.7104

Abstract: Proliferation in the number of vehicles is leading to problems of vehicles parking at an appropriate place especially the car parking. This indirectly leads to traffic congestion. This is because of the fact that current transportation infrastructure and car park facility are unable to cope with the arrival of large number of vehicles on the road. To alleviate the aforementioned problem, the proposed system is a Smart Parking Management System that helps users to automatically find a free parking space with a smaller amount. Smart Parking involves use of Ultrasonic sensor, Arduino Uno, ESP8266-01 Wi-Fi Module, Cloud server. IOT based new parking platform enable to connect, analyze and automate data gathered from devices and execute smart parking possible. Smart parking would enable vehicle occupancy, monitoring and managing of available parking space in real-time that reducing the environmental pollution. Proposed system provides optimize usage of parking space and get considerable revenue generation.

Protection of Three Phase Power Transformer

Ankit Kondkar, Ankita Bhosale, Aditya Jawale, Pranay Salavkar, Rekha Sonune

DOI: 10.17148/IJIREEICE.2019.7106

Abstract: Transformers must be protected in order to limit the damages due to abnormal currents and over voltages. The role of protection is to ensure that these withstand limits can never be exceeded, therefore clearing the faults as soon as possible. Different transformers demand different schemes of transformer protection depending upon their importance, winding connections, earthing methods and mode of operation. The protection of transformer is important as it involves human risk as well as economic risk. There are different types of protection provided to a power transformer such as a Differential protection and Restricted Earth fault protection which together are known as Primary Protection Schemes; Backup Protection is also employed namely three phase overcurrent and earth fault. There are different types of protection equipment‟s available on a transformer like Buchholz relay, winding temperature indicator, oil temperature indicator, oil surge relay and pressure release valve etc. To avoid any danger to human life as well as to save transformer from any kind of damage, protection to a transformer should be provided. Index terms: Buchholz, Differential, Restricted Earth fault, Oil Surge Relay, Pressure Release Valve.

V/F Speed Control Technique of Three Phase Induction Motor

Omkar Gawade, Onkar Utekar, Swapnil Ranjane, Ashish Raut, Rekha Sonune

DOI: 10.17148/IJIREEICE.2019.7107

Abstract: When we connect an induction motor directly to the main supply it can run only at its rated speed. However, many operations need variable speed applications. Also we felt that in many applications input power is directly proportional to the cube of motor speed. Today about 90% of all industrial motor applications use three phase induction motor because they are simple in design, easy to maintain and are less costly than other design. There are many induction motor control techniques in practice today, but the most popular control technique is by generating variable frequency supply, which has constant voltage to frequency ratio. This technique is popularly known as V/F speed control technique. The torque developed by the induction motor is directly proportional to the ratio of the applied voltage and the frequency of supply. By varying the voltage and the frequency, but keeping their ratio constant, the torque developed can be kept constant throughout the speed range. This is exactly what VF control tries to achieve.

Keywords: Speed control, variable frequency, three phase induction motor, PWM, IGBT, simulations.

Sagar T. Telrandhe, Swati S. Pande, Sheetal V. Umredkar

DOI: 10.17148/IJIREEICE.2019.7108

Abstract: This work deals with designing a brushless DC (BLDC) motor driven water pumping system powered by a Solar Photovoltaic (SPV) array with Quasi-Z Source Inverter (q-ZSI). The Induction motor (IM) driven water pumps can be replaced by the BLDC motor driven water pumps due to its several advantages over IM. Also, the Quasi- Z source Inverter has various advantages over Current Source Inverter (CSI), Voltage Source Inverter (VSI) and Z- Source Inverter (ZSI) as it provides better shoot through states which in turn provides a single stage power conversion. The propriety of the proposed system is cleared through its performance analysis using MATLAB/Simulink based simulated results.
