Comparison of artificial intelligence techniques for the enhancement of power quality

Abstract: Artificial Intelligence techniques are the recent trends used for the enhancement of power quality. This paper deals with analysis and comparison of different artificial techniques for harmonic reduction in the source current. Artificial Intelligence may include Fuzzy logic and Artificial Neural Network. The purpose of the simulation is to enhance the power quality by using the concepts that cannot be expressed as "true" or "false" but rather as "partially true" called as Fuzzy logic and intelligent features of the neuron cell. Shunt Active Filter is one of the controller that can be used for suppress the source current harmonics and compensates the reactive power. Hysteresis current controller is used to control the switching of Voltage Source Inverter. The D-Q Frame theory is used to generate the reference compensating current. Simulations are carried out in MATLAB environment using power system toolbox.

Comparative Study on Strengths and Weaknesses of Trust Algorithms in Semantic Web Based Networks

Abstract: Trust is an essential element of semantic web(SW)and networks associated with it. In this paper, we will discuss the properties, approaches and strategies of trust that is required in a trusted environment. Then, we will discuss two types of SW networks-peer-to-peer and social networks and all the algorithms that compute trust under these networks. After analysing all the trust algorithm we will compare these algorithms based on their strengths and weaknesses

Conceptual design and development of pneumatically controlled flexible fixture and pallets

Abstract: Fixture performance influences the product manufacturing quality, productivity and cost. Flexible fixtures (FF) provide solution to the problem of costly redesign of fixtures due to changes in dimensions/geometry of parts to be manufactured. Various areas related to design of FFs have already been very well described by various renowned authors. This paper carries out the conceptual designing of pneumatically controlled FF and pallets for machining (drilling and milling) operations. Pneumatic cylinders and electric motors were used as actuators. The first part considers introduction and literature review with significant researches and requirements of fixtures over time. After that, different aspects related to fixture design have been presented to give a deep and quick understanding of fixture design and its criteria for drilling and milling heads. Then, conceptual designing of pneumatically controlled FF and pallets has been discussed. The shortcomings of the existing studies are stated and future directions are proposed.

Investigating the benefits and challenges of the implementation of ISO 9001 and ISO 14001 in the aerospace industry

Abstract: Aerospace companies implement certain quality management and environmental standards, e.g. ISO 9001 and ISO 14001 requirements specific to the aerospace industry. The big question is whether the implementation of the ISO standards has provided its hope for returns. The aim of this research is therefore to analyze the benefits and challenges of the implementation of ISO 9001 and ISO 14001 in the aerospace industry. This study aims to investigate two underlying subjects – quality management and environmental management, and explore how they influence firm performance and how they are implemented in the aerospace industry. Nine participants from different aerospace companies were interviewed. The results suggest that these companies were put under pressure internally and externally by the customers for pursuing the certification. Major factors that affect the implementation include size of company, employee participation, and company commitment. It also discovered that ISO 14001 seems to mainly impact the managers and employees related to environmental work. This study found that the larger the company size, the more sensitive it becomes toward customer pressure on commitment to sustainability.
