Ethics and Values in business mean principle or code of conduct that govern business transaction. These are meant to analyse problems that come up in day to day course of business operations. Apart from this it also applies to individuals who work in organisations, their conduct and to the organisations as a whole. In the increasingly conscience focused market places of the 21st century, the demand for more ethical business processes and actions, ethicism is increasing. This paper takes a peek into different sectors of an enterprises that is manufacturing , food, education, advertising and media , etc. See how ethical code of conduct already are and what are the steps needed to maintain a good corporate ethics.Keywords

Mobile ad hoc network (MANET) is composed of mobile nodes that can be formed without the need of any pre-existing infrastructure or centralized administration. Mobile nodes independently form a network over radio links in an ad-hoc fashion. Routing is done arbitrarily and randomly, due to frequent and unpredictably changes in network wireless topology. To provide and maintain better connectivity for this type of network, a number of routing protocols have been proposed. Simulator models are used for the performance evaluation of the routing protocols before their implementation in real life. CBR traffic is the commonly used traffic type to evaluate MANET routing protocols performance. But TCP traffic is connection oriented and more reliable than CBR traffic. More than 80% of the Internet traffic is based on TCP. Therefore it is necessary to analyze the impact of TCP traffic types on MANET routing protocols before selecting a particular protocol for the network. In this paper, the performance of a most widely used reactive MANET routing protocol "Ad hoc On-demand Distance Vector Routing" (AODV) is optimized on TCP traffic by using Taguchi design of experiment (DOE) approach. We inferred the main effect of five factors (Performance Parameters) i.e., No. of nodes, Pause time, Maximum node movement speed, Maximum no. of concurrent connections and Network area. For the evaluation purpose five performance metrics i.e., Routing overhead, Average end-to-end delay, Packet delivery ratio, Throughput and Energy consumed have been considered. The study also uses Taguchi quality loss function for tackling multiple performance metrics and various network parameters simultaneously. Taguchi experimental design comprising of L8 orthogonal array of two levels for each parameter is used to organize the parameters and their range. A statistical analysis of means (ANOM) and analysis of variance (ANOVA) is performed to find the statistically significant optimal values of these parameters in order to achieve the best performance of AODV MANET routing protocol.

A mobile ad hoc network (MANET) is a collection of mobile nodes dynamically forming temporary network without the use of any existing network infrastructure or centralized administration. To provide and maintain better connectivity for this type of network a number of routing protocols have been proposed. Software Simulators are used for the performance evaluation of the routing protocol before implementing it in real life. CBR traffic is the commonly used as traffic type to evaluate MANET routing protocols performance. But TCP traffic is connection oriented and more reliable than CBR traffic. Therefore it is necessary to analyze the impact of TCP traffic types on MANET routing protocols before selecting a particular protocol for the network. The improvement of one performance metric may be a degradation of another performance metric. A single setup of experiment may be best for packet delivery fraction but the same setting may not yield best results for normalized routing load. In this paper, we optimize the performance of Dynamic Source Routing (DSR) using TCP traffic with multiple performances metric. The Taguchi‟s quality loss function concept has been employed to deal with multi performance metrics. Taguchi experimental design comprising of L8 orthogonal array of two levels for each parameter is used to organize the parameters and their range. A statistical analysis of means (ANOM) and analysis of variance (ANOVA) on quality loss function is performed to find the optimal values of factors which are statistically significant in order to achieve the best performance metrics of DSR routing protocol. The ANOVA results shows that number of nodes and number of connections are the most influential factors on all performance metrics. Taguchi approach suggests that optimal values for number of nodes and number of connections must be kept at low level and value of pause time must be kept at high level.Keywords

In this study the performance and emission characteristics of diesel engine fueled with diesel/Argemone biodiesel blends has been evaluated. An experiment was conducted on an indirect injection (IDI) compression ignition (CI) engine using diesel and diesel/Argemone biodiesel blends. The result shows that with an increase in Argemone biodiesel blend ratio (up to B30) the performance characteristics such as brake thermal efficiency, brake specific fuel consumption, indicated thermal efficiency, indicated mean effective pressure improved and resulted in significant reductions in CO and HC emissions. However, an increase in CO2 and NOx emissions was observed for all biodiesel blends. The maximum value of brake thermal efficiency of 33.57 per cent was obtained for B30 at full load @2500 rpm. The blends showed deterioration in brake thermal efficiency and brake specific fuel consumption at partial loads and high rpm conditions. The comprehensive analysis of experimental results shows substantial improvement in engine emissions and performance characteristics by the utilization of 30 per cent AOME and without carrying out any engine modification.

Gas Tungsten Arc Welding (GTAW) uses a non-consumable tungsten electrode to produce the weld joint. The properties of the welded joints are affected by a large number of welding input parameter such as welding current waveform, welding current, welding speed and gas flow rate, these parameters plays a very significant role in determining the quality of a weld joint. In this work butt weld joint of Copper and Stainless Steel (SS304) is obtained by using autogenous GTAW process. The trial runs had been conducted to find out optimum range of process parameters. Four parameters such as welding current, welding speed, welding torch angle and gas flow rate are considered. The effect of these parameters on mechanical properties such as tensile strength, impact strength, bend strength and hardness of weld joint is analyzed.Keywords
