Abdul Ohab, Md.Tahasin Abid, Utpal Chandra Das, Md. Zahirul Islam, Amir Shohel
Abstract: The Internet of Things (IoT) gadgets have turned out to be well known in various spaces, for example, electronics Health ( e-Health), e-Home, online business, and e-Trafficking, and so forth. With expanded arrangement of IoT gadgets in reality, they can be, and now and again, as of now are liable to malicious attacks to trade off the security and protection of the IoT devices. While various analysts have investigated such security difficulties and open issues in IoT, there is a deplorable absence of an orderly investigation of the security challenges in the IoT scene. In this report, we go for connecting this gap by directing a careful investigation of IoT security difficulties and issues. A definite investigation of IoT attack surfaces, frameworks, security issues and has been presented. A brief summary of comparison among the IoT frameworks those can provide countermeasures against various security attacks in IoT also been addressed

Abstract: The objective of this paper is to present a detailed study to design, model and simulate buck regulator with an analog lag lead compensator cascaded by sign inverter, then transpose into its equivalent digital form. The ease of implementation and the advantages given by the adaptability to the changes in the closed loop enable the digital controllers to become widely used during the last few decades. This is attributed to the tremendous growth in integrated circuits (ICs) technology and skyrocketed development in semiconductor devices which in turn fulfill the highly demanded microprocessors to more current at low voltages. Specifically, they received special attention in different applications such as renewable energy sources, Switched Mode Power Supplies (SMPS), drive systems, and High- Voltage DC (HVDC) transmission, etc. We have performed two algorithms, the first to design analog compensator aiming at achievement of specified requirements while the second to obtain the six transfer functions concerning the various (state/input/output) variables of the buck converter based on the small signal and averaged state space models. This facilitates obtaining an appropriate equivalent digital compensator using Bilinear Z-Transform (BZT), Matched Pole-Zero (MPZ) and Zero Order Hold (ZOH) methods. Also, simulative results have been depicted via MATLAB/Simulink model utilizing SimElectronics Toolbox. Moreover, these models represented by the state and output equations, enable the other modeling approaches to be computationally implemented. A special emphasis of our work is placed on the circuit and transfer function models. In addition, the dynamic response of our intended compensator under input voltage change and load current variations is illustrated. Simulation results ensure that the output voltage and inductor current can return to steady state even when they are affected by such variations, with a small overshoot and settling time for the investigated waveforms. As a result of the above, a precise and robust closed loop controller that can satisfy high degree of stability and performance conditions of the DC-DC synchronous buck regulator has been accomplished. Finally, the performed algorithms have paved the way towards practical implementation by microcontroller /DSP controller/ FPGA controller. In case of a change in converter parameters, the new values of the z-coefficients for the digital compensator are evaluated and programmed by software and no need for the designer to solder or redesign the printed board which is in opposite to the analog compensators.

Abstract: Technological importance have been a great support for making decisions in various fields especially in agriculture. The development of agriculture has been on under development for the past few years due to lack of Agriculture knowledge and environmental changes. The main aim of this paper is to reach farmers for their awareness, usage and perception in e-Agriculture. The study used statistical survey design technique to collect data from farmers for their awareness in e-Commerce. The results obtained indicated the level of awareness is less such that there is a need for e-agriculture for their support. E-Agriculture is a platform for supporting marketing of agricultural products.
Abstract: This preeminent PV technology work on contagious photons of light & exploits them to generate free electrons. Electricity generation is done by these free electrons. The solar PV cell or power panels are the main & effective technology for solar power generation. This is a semi converter device that converts the solar rays into useful electrical energy (power). This paper also deals with the power generation process with the several outputs like P-V characteristics at different irradiance level, DC voltage provided by the boost converter using P&O maximum power point technique.

A review of Fingerprint Recognition Based Automatic Attendance System

DOI: 10.17148/IJIREEICE.2019.71004
Abstract: Our paper aims at designing a student attendance system which could effectively manage attendance of students at institutes like NIT Rourkela. Attendance is marked after student identification. For student identification, a fingerprint recognition-based identification system is used. Finger prints are considered to be the best and fastest method for biometric identification. They are secure to use, unique for every person and do not change in oneβs lifetime. Fingerprint recognition is a mature field to- day, but still identifying individual from a set of enrolled fingerprints is a time taking process. It was our responsibility to improve the fingerprint identification system for implementation on large databases e.g. of an institute or a country etc. In this paper, many new algorithms have been used e.g. gender estimation, key based one to many matching, removing boundary minutiae. Using these new algorithms, we have developed an identification system which is faster in implementation than any other available today in the market. Although we are using this fingerprint identification system for student identification purpose in our paper, the matching results are so good that it could perform very well on large databases like that of a country like India (MNICPaper).
This system was implemented in Matlab10, Intel Core2Duo processor and comparison of our one too many identification was done with existing identification technique i.e. one to one identification on same plat form. Our matching technique run sinO (n+N) time as compared to the existing O(Nn2). The finger print identification system was tested on FVC2004 and Verifinger databases.
