Analysis of rigid raft overlying the granular pile with the effect of stiffness of bearing stratum

Abstract: With the use of piled raft, the load carrying capacity of the raft is enhanced and its differential settlement is reduced. As an economical alternative to conventional pile i.e. steel or concrete p...

Performance analysis of SAPF based on self tuned harmonic filter with fuzzy logic controller

Abstract: This article present software implementation, evaluation and simulation of three phase three wire(3-ph-3w) shunt active power filter (SAPF). It is able to harmonic mitigation, reactive power mitigation and power factor correction (PFC) under balanced diode rectifier nonlinear load with resistive inductive load as well as time series change of supply voltage amplitude. The p-q theory with self-tuning harmonic filter (STHF) is exercised for fundamental reference supply current generation. The novelty of control topology implemented in proposed brief is brought STHF which directly extracts voltage and current fundamental components in α-β axis without use of synchronizing unit vector element. Fuzzy logic based controller has been designed in MATLAB/Simulink platform to evaluate system performance under non-linearity and time series supply voltage amplitude variation. It will be proved that a define approach has good dynamic response. A simulation performance and results will illustrate better performance in comparison with classical extraction methods will be obtained. The usefulness of proposed SAPF is demonstrated through simulation using sim-power-system and embedded function integrated in MATLAB/Simulink.

A Construction of Security Enhanced and Efficient Handover AKA Protocol in 5G Communication Network

Abstract: In order to accommodate the increasing security demands of Internet of Things (IoT)-based applications, the Third Generation Partnership Project (3GPP) has announced the Fifth Generation (5G) communication technology with the security amendments such as flexible placement of User Plane (UP) functions and network slicing which were not achieved in Fourth Generation (4G) Long Term Evolution (LTE) network. In this paper, we identified the security weaknesses in existing 5G handover protocol such as false base-station attack, lack of Key forward/backward secrecy (KFS/KBS), Denial of Service (DoS) attack, and high network complexity. In order to modify the above issues, we construct a security enhanced and efficient handover authentication and key agreement protocol in 5th genration communication network. The formal analysis of proposed protocol is carried out by AVISPA tool to prove its correctness. Finally, the performance evaluation of the protocol is shown with existing 5G handover protocol. The analysis shows that the proposed protocol has improved results in terms of communication and computation overhead.

Relevance of hydrogen as an alternative of electricity for energy transmission and transportation of water in India

Abstract: Presently the world's energy system is moving towards the clean energy options. Hydrogen can be one of them, because of its several inherent properties. It is a clean energy vector and water is the only exhaust produced, when burnt in the presence of air. Hydrogen economy includes the replacement of fossil fuels, so that it can also help in reducing the global CO 2 emission. Hydrogen provides an alternative way of storing energy similar to the electricity. This paper introduces a new concept of transmitting energy in the form of hydrogen with an added advantage of producing water. So that both the shortage of water and power can be fulfilled by a single means. In this paper, the main fields of hydrogen economy: hydrogen production; delivery; and handling of hydrogen are discussed with their economic aspects. The transmission of energy in the form of hydrogen with the cost of different phases for 200 km of transportation are also discussed. A study of sending energy in the form of hydrogen from Kota to Ajmer in the state of Rajasthan, India is also presented. Hydrogen transportation as energy provides both electricity and water at the endpoint, which is particularly useful during summer as many parts of India have both shortages of water and electricity.

4QAM OFDM Visible Light Communication using Laser

Abstract: A visible light communication (VLC) system with 4QAM-OFDM is formed and simulated using 450 nm CW laser (CW laser) with a modulator at the input side and at the receiving side photodetector is used. VLC system Simulation is done by working on Optisystem 12, a constellation of VLC obtained at 250m/10Gbps. the benefit of CW laser along with 4 QAM OFDM improve the VLC system for free space communication Significant. With the help of CW Laser at visible frequency aspect can be seen as an advanced class of an input carrier which has the potential to accomplish data rate of high speed, high communication distance, as well as easy supervision and furnishing. By using 4 QAM OFDM we get clear constellation diagram. In this paper, we evaluate the performance of optical to electrical power conversion, Clear constellation diagram of VLC System corresponding distance from the transmitter to receiver.
