Internet of Things, the one paradigm many vision idea is ruling the world. By 2025 over trillions and trillions of objects will be connected to the internet. Social networking concepts are revolutions beyond IoT. One of the many visions of IoT is to make objects not only smarter but also socially conscious. A new paradigm named Social Internet of Things evolved which integrated two technologies namely Internet of Things and Social Networking. A SIoT comprises of socially aware smart objects that can autonomously establish and enable collaboration with other smart objects that are friends. In this paper we study the role, characteristics of social objects and their relationships. Five kinds of relationships are identified. These relationship and characteristics helps in revealing the level of trust between objects. Experiments were conducted for 85 social objects in an office environment and the types of objects, their relationships, interest, activities etc were discovered.

There is an increasing interest in many countries to search for suitable alternative fuels that are environment friendly. Although straight vegetable oils can be used in diesel engines, their high viscosities, low volatilities and poor cold flow properties have led to the investigation of various derivatives. Biodiesel is a fatty acid alkyl ester, which can be derived from any vegetable oil by transesterification. Biodiesel is a renewable, biodegradable and non-toxic fuel. In this study, Brassica oil (Brassica juncea seed oil) was transesterified with methanol using sodium hydroxide as catalyst to obtain brassica oil methyl ester (BOME). This biodiesel was tested in a single cylinder 4 stroke diesel engine (Kirloskar) to evaluate the performance characteristics. © 2006-2012 Asian Research Publishing Network (ARPN).

In this paper, the grey-based Taguchi method was used to optimize the fabrication parameters with mechanical properties (multiple performance characteristics) in roselle fiber with (5 % wt) Coconut shell powder (CSP) reinforced vinyl ester (RFRVE) composites. Composite plates were prepared based on the Taguchi’s L27 orthogonal array using hand lay-up technique at room temperature. Fabrication parameters namely fiber length, fiber content, and fiber diameters were optimized based on the grey relational grade (GRG) as performance index obtained from the grey relational analysis to get the maximum level of multiple performance characteristics such as the tensile strength, the flexural strength, and the impact strength. The results show that the fiber content is the most significant fabrication parameter which greatly affects the mechanical properties of RFRVE composite compared to the fiber length and the fiber diameter. It was proved that the multiple performance characteristics of the plant based natural fiber and particle reinforced polymer composites can be effectively improved by this method. © 2015, Central Institute of Plastics Engineering & Technology.

In this paper, the grey-based Taguchi method was used to optimize the fabrication parameters with mechanical properties multiple performance characteristics (MPC) in sisal fibre-reinforced vinyl ester (SFRVE) composites. Composite plates were prepared based on the Taguchi’s L27 orthogonal array using hand lay-up technique at room temperature. Fabrication parameters, namely fibre length, fibre content and fibre diameters were optimized based on the grey relational grade as performance index obtained from the grey relational analysis to get the maximum level of MPC such as the tensile strength, the flexural strength and the impact strength. The results show that the fibre content is the most significant fabrication parameter which greatly affects the mechanical properties of SFRVE composite compared to the fibre length and the fibre diameter. It was proved that the MPC of the plant-based natural fibre-reinforced polymer composites can be effectively improved by this method. © 2015 Engineers Australia

The Internet is populated with billions of electronic gadgets that have become a part of our fabric. Internet of Things is gaining popularity in at most all applications from smart buildings, intelligent transportation, healthcare and defence. IoT is a many vision one paradigm technology. One of the many visions of IoT is to make 'Things' social. Social Internet of Things (SIoT) is a young paradigm that integrates IoT and Social networking principles where Things are not only autonomous and smarter but also socially conscious. The authors propose a trust management scheme to facilitate trustworthy automatic decision making based on behaviour of objects. The authors use SIoT Trust metrics namely direct trust, centrality, community interest, Cooperativeness, Service Score to compute Trustworthiness among objects. The Expected trust and periodic trust updates evidently identify the presence of 'on off' selective forwarding attacks. The authors demonstrate the advantages of the proposed scheme with other existing trust management schemes in the literature. © The Institution of Engineering and Technology 2017.

Latest trend in increasing the performance characteristics of precision machines is reducing error in machines. Today research is focused on Machine tool accuracy. The effect of thermal error contributes to major part of 70% of volumetric error. The present study aims to establish a new compensation method for CNC Turning centre. Selection of proper temperature variables is a great task in thermal error compensation. In this paper 3 thermal process variables namely spindle speed; temperature and time are used to create thermal error models. Using ANSYS simulation experiments are created. © (2014) Trans Tech Publications, Switzerland.

A complete simulation of the transmission performance for Holographic ROADM (Reconfigurable Optical Add-Drop Multiplexer) designs is Presented in this paper. These devices can address several wavelengths from the input to different output fibers, according to the holograms stored in a SLM (Spatial Light Modulator), where all the output sare equalized in power. All combinations of the input wavelengths are possible at the different output fibers. To simulate the transmission Performance of the EH-ROADM,a software program, from Optiwave, has been used. © 2013 IEEE.

“Energy is a single greatest challenge facing humanity” by Nobel Laureate Richard Smalley. Use of fossil fuels can trigger global energy crisis and increased global warming hence there is considerable interest in research fraternity on green energy production. According to recent survey by UNEP more than 1 billion of world population does not have access to constant source of electricity. Renewable and clean forms of energy are one of the society‟s greatest needs. We lack adequate sanitation and economic means to afford for it. Microbial Fuel Cell help in working to address the needs. MFC work on the complex organic matters and they convert this chemical energy into the electrical energy by the catalytic action of the microorganism. Electrons produced by the metabolism of microorganism are utilized for the generation of electricity and the setup must be operated at or near about ambient temperature and nearly neutral solution. This study is to demonstrate the bio-energy generation from the complex pollutant aniline which is prepared synthetically from the laboratory by using the specific bacteria Pseudomonas aeruginosa [MTCC 8076]. Optimization of process parameters such as electrode selection, biofilm formation, electrolyte concentration variation were carried out. Open circuit voltage and current was measured for a period of 21 days. For the best optimization results the maximum open circuit voltage obtained was 1.07 V and current of 0.6 mA. © 2015 CAFET-INNOVA TECHNICAL SOCIETY. All rights reserved.

Chromatic Dispersion is one of the major (Linear) effect in Optic transmission System. Dispersion causes broadening of transmitted pulses that leads to Inter Symbol Interference (ISI). In this paper, analysis of phase conjugation in compensating dispersion in an optical transmission system with 10 Gb/s as bit rate and for a distance of over 50,000 kms. The required number and fashion of OPC to be used for effective dispersion compensation were analysed in DWDM systems. Simulation results were obtained using OPTSIM software from Rsoft. © 2011 American Institute of Physics.
