This work presents the application of an adaptive non-dominated sorting genetic algorithm (ANSGA II) for optimal insertion of distributed generators (DG) in radial distribution systems. In order to extract the maximum benefits of DG, an objective function is formulated with consideration of power loss reduction, reduction of annual operation cost of DG units and annual emission cost of pollutant gases. The proposed method is successfully experimented on a 33-bus distribution system and a comparative analysis with NSGA II is presented with different bi and tri objective cases of DG integration. © 2019 IEEE.

Body centric wireless communication refers to inter human and intra human connectivity for various medical and rescue application. A compact and flexible printed textile antenna operable at 5.2GHz for WiMAX and WLAN application has been presented. Wearable 1mm thick blue jeans having relative permittivity 1.67 and loss tangent of 0.01 has been used as substrate material. Return loss, VSWR and radiation pattern have been presented to show the good agreement between the simulated and measured results. Free space and near body scenarios were considered separately while designing and in measurement of results. The proposed antenna exhibits omnidirectional radiation pattern for near body case with suitable gain of 5dB for body centric applications. Simulations were carried out using HFSS (High Frequency Structural Simulator) and measurements were performed using vector network analyzer and anechoic chamber. © 2012 IEEE.

Cloud computing is an efficient technology to improve the performance of organizations by providing flexibility in architecture and reduction in costs. Dynamic resource pooling, virtualization, on demand service and high availability are some of the advantages provided by cloud computing. However, open and distributed architecture as well as internet access, have caused cloud environments to be risky and vulnerable. Privacy, confidentiality, and authentication are some of security concerns which need to be addressed. In this paper we propose a secure mechanism for authentication and session key distribution. For this purpose, we have chosen Kerberos 5 protocol that is one of the best known authentication and key distribution systems. But, this protocol is vulnerable to password guessing attack. Hence, we improve the Kerberos 5 with Strong Diffi-Hellman-DSA key exchange algorithm and the user's fingerprint samples. This approach provides a protocol which is highly secure. We solve the password guessing attack vulnerability using Strong Diffi-Hellman-DSA Key Exchange algorithm. Also, the use of biometric data provides a non-repudiation mechanism that can address the limitation of password-based authentication, such as the tendency of users to choose a simple password. In addition, we implement this scheme in cloud computing systems and use an enhanced approach for fingerprint template protection. Finally, in the last part we show how this scheme can protect cloud computing systems against different attacks. © 2016 IEEE.

Real-time Mining [1][2][3] and Streaming of Data have become more popular in the data field, with access to the fastest and the latest data. Real-time Data Mining seeks the development of a real-time framework for enhancing resource efficiency while minimizing environmental impact. Real-time analysis has a huge rate of change in data, and it has to be processed and updated frequently. Data mining is an interdisciplinary subject comprising machine learning, statistics, database technology, and artificial intelligence. Data mining primarily aims to decipher the past and anticipate the future through data exploration and analysis, known as Knowledge Discovery in a Database. Data mining attempts to store the data in the local data set hosted by local computers connected to the computer networks. In the real world, data has become abundant with the advent of data streams, invariably raising the question of data storage. Also, data will not be clean when received in the form of streams. Non-clean data cannot be stored in the database and will not be effective for data analysis. An organized repository of related information must be stored in the database;hence, data must be cleaned before storage. Data is cleaned as per the analysis required of the data. Once the data is cleaned, the question of the memory to store the data arises. Storing real-time data is a relatively trivial process, and there should not be any missing data from the streams. Data cleaning and memory management in real-time data is always challenging. This research proposes a novel methodology for data cleaning and management of memory to overcome these issues. An algorithm is executed using the scheduler at the specific interval separating the test and trial data. Trial data will be used for further analysis, and test data will be discarded at the specific interval. The test data will be a derivative of trial data. © Grenze Scientific Society, 2024.

The work deals with the mechanical characterization of Kenaf and Kevlar fiber reinforced epoxy-based composites. The tensile, flexural, double shear, impact, hardness and de-lamination tests were conducted on composite laminates developed through hand lay-up process. Morphological analysis was conducted to examine the split surface of the tested specimen. The experimental investigation reveals that the mechanical properties of epoxy composites were enhanced by the hybridization of Kenaf and Kevlar fiber. © 2020 Elsevier Ltd. All rights reserved.

Aluminium metal matrix composites (AMMC) have potential demand in various structural applications such as aerospace, construction, automobile and even in medical fields due to their remarkable characteristics in comparison with conventional alloys. Al7050 is widely adopted and suitable alloy among the Al-7xxx series for transportation applications. The physical, mechanical, tribological and microstructure characteristics of Al7050 metal matrix can still be improved with the addition of suitable reinforcing materials. The objective of this review is to provide an overview of titanium as reinforcement material in Al7050 MMC and to elaborate on the change in mechanical characteristics due to the addition of reinforcement. © 2020 Elsevier Ltd.
