IIJ03-01: Implementation of Advanced Encryption Standard on FPGA – A Review
AUTHORS: Shobhna Patel, Prof. Amrita Khera
Abstract – The paper presents a comparative survey of private-key cryptographic algorithm implementations on field programmable gate arrays (FPGAs). The performance and flexibility of FPGAs make them almost ideal implementation platforms for cryptographic algorithms, and therefore the FPGA-based implementation of cryptographic algorithms has been widely studied during the past few years. The authors analyze FPGA-based different implementations of Advanced Encryption Standard (AES) in terms of speed, area and implementation techniques. These algorithm implementations provide a good overview of the field of private-key cryptographic algorithm implementation.

IIJ03-02: Remedial outcome of Voltage Sag In A Doubly Fed Transmission Line Using A Dynamic Voltage Restorer
AUTHORS: Mr Pawan Kumar Sahu, Prof. Vinay Pathak
Abstract: Changing electric load and higher power move in a wide interconnected system lead stoserious, security need in control framework activities additionally if a sudden blame happens there is an adjustment in voltage profile which can prompt a sudden harm on stack end. These voltage lists are remunerated at generator side by different strategies however at the heap end there is a possibility. to stay away from such droop at stack side a tangle lab demonstrate is proposed in which a transmission line is bolstered with two sources out of which one is a breeze source and after that is subjected to a 3 stage blame. the voltage droop which happens is repaid in the other model at same moment when DVR Dynamic voltage restorer is customized and is associated at the midpoint of framework. The outcomes acquired demonstrates that the voltage is repaid and profile is adjusted, DVR utilizes the vitality source in all around planned way and infuses necessary AC voltage to framework.

IIJ03-03: Performance of Three Phase 11-level Inverter with reduced THD using different PWM Techniques
AUTHORS: Ashish Nayak, Vinay Pathak, Namrta Sant and Nitesh Singh
Abstract: When contrasted with customary inverter topologies like diode clamped and capacitor cinched inverters, the cascaded multilevel inverter has lesser sounds and in addition lower switching stress. The cascaded topology has more number of control changes prompting more noteworthy warmth misfortunes, bigger size, higher cost and more entryway drive hardware. The proposed arrangement contains less number of switches and creates lesser harmonics in the yield voltage than the conventional topology. The proposed topology has been designed using MATLAB simulink commonly used block and results are compared for various PWM techniques to obtain minimum THD. A shunt capacitor is connected across each phase of the inverter to smooth out the harmonics.
IIJ03-04 : Study on Strength and Durability Properties of High Performance Concrete by Replacing Sand with Robo Sand and Cement with Fly-ash and Using Mineral Admixtures
AUTHORS: D.Kanaka Durga, Ms.K.Prafulla Devi
Abstract: High Performance Concrete (HPC) is a concrete meeting special combinations of performance and uniformity requirements that cannot be always achieved routinely by using conventional constituents and normal mixing. In this experimental study the partial replacement of cement and fine aggregate by the fly ash and robosand respectively. Recently natural sand is becoming very costly because of its demand in the construction industry and BAN of sand mining in rivers. So research for the alternatives of natural sand is going to find in economical way to meet the high performance characteristics. In this path the manufactured sand called ROBOSAND is the new material i.e., arrived in the world of concrete to fulfill the requirements of Natural sand. The other material FLYASH comes from the industries as a by-product which is freely available. This project mainly focuses on achieving high performance characteristics of concrete by comparing M80 and M90 grades. The strength, workability and Durability properties for both grades are compared by varying the percentages of ROBOSAND with natural sand by 0%, 25%, 50%, 75% and 100% together with fly ash of 20% replacement in cement and 5 % silica fumes was added to the above mixture. The compressive strength, split tensile strength and flexural strength are compared for both grades and results are tabulated and the optimum percentages are concluded.

IIJ03-05 : A review paper on numerical simulation to optimize the ventilation design condition of school building using CFD
AUTHORS: Devendra Veer Vikram Shahi , Mr. Vardhan Singh Nayak, Mr. Arvind Gupta
Abstract: Summer air conditioning represents a growing market in buildings worldwide, with a particularly significant growth rate observed in European commercial and residential buildings. Heat-driven cooling technologies are available, which can be used in combination with solar thermal collectors to alleviate the burden caused by air conditioning on the electric utilities and the environment. Solar air conditioning has progressed considerably over the past years as a result of efforts toward environmental protection and new developments in components and systems, and significant experience has been gained from demonstration projects. The main obstacles for large scale application, beside the high first cost, are the lack of practical experience and acquaintance among architects, builders and planners with the design, control and operation of these systems. This paper describes the main results of the EU project SACE (Solar Air Conditioning in Europe), aimed to assess the state-of-the-art, future needs and overall prospects of solar cooling in Europe. A group of researchers from five countries has surveyed and analyzed over 50 solar-powered cooling projects in different climatic zones. The paper presents a short overview on the state-of-the-art and potential of solar-assisted cooling and air conditioning technologies. The results of the study, including a database of the surveyed projects, an evaluation of these projects on a uniform basis, an economic analysis tool, user guidelines and a multimedia tool—are presented. The potential energy savings and limitations of solar thermal air conditioning in comparison to conventional technologies are illustrated and discussed.
