This paper presents the simple voltage regulation scheme using a three-phase static VAr compensator (STATCON) for a stand-alone self-excited induction generator (SEIG) that uses variable-speed wind generation system. Most of the loads are inductive and need an equal amount of leading VArs, which is generated by the STATCON and injected at point of common coupling instantaneously. The one cycle control technique is considered and modified to implement for VAr compensation of SEIG voltage regulation. To emphasis the controller characteristics, a STATCON is designed for a 3-Ø, 0.75 kW, 415 V, 1.8 A Induction Machine and tested in simulation using MATLAB/SIMULINK software. © 2016 Taylor & Francis

International Review on Modelling and Simulations | Year: 2013

This paper describe the methods employed to control voltage and frequency of a 3-Ø stand-alone self-excited induction generator (SEIG) driven by a variable speed wind turbine. An attempt made to control the terminal voltage of SEIG by using a 3-Ø diode clamped multilevel converter (DCMLC) based STATCOM operation. A 3-Ø diode bridge rectifier with a d.c chopper circuit is employed to control the frequency of generated voltage. The VAr required by the load and the machine owing to changes in magnetizing reactance's are compensated by DCMLC-STATCOM operate with full load excitation capacitance. To emphasis the controller characteristics, mathematical model of the controller is developed and implemented in MATLAB / SIMULINK software. © 2013 Praise Worthy Prize S.r.l. - All rights reserved.

Monitoring of drop impact damage is necessary because it produces invisible damage in composite materials without any visible mark on the surface. Monitoring of drop impact damage was carried out on Woven Glass Fibre Reinforced Polymer (WGFRP) composite laminate through Acoustic Emission (AE) technique. The significant AE parameters like signal strength, root means square value, counts and counts to peak were determined for drop impact damage. Impact damage tolerance was predicted using Artificial Neural Network (ANN) trained with AE parameters as input and impact damage tolerance as output. The predicated impact damage tolerance was with average error tolerance of 3.35%. The proposed network finds very good agreement for prediction of impact damage tolerance of impact damaged WGFRP composite laminate in real time application. © 2014 Elsevier Ltd.

Insight: Non-Destructive Testing and Condition Monitoring | Year: 2012

Online monitoring of drop impact damage is carried out on woven glass fibre-reinforced plastic (WGFRP) composite laminate through the acoustic emission technique. The acquired acoustic emission (AE) signals during the impact test were analysed. The AE parameters, such as: 1. AE signal strength; 2. counts; 3. counts to peak; and 4. RMS values, were found to be more sensitive to impact damage in descending order. If drop impact damage in woven GFRP composites is above a critical value, the material is replaced or repaired. The critical value of drop impact damage can be determined by the impact damage tolerance method through the compression strength after impact test (CAI). The impact damage tolerance value is correlated with AE parameters, which are obtained from online monitoring of drop impact damage. This correlation will be useful for online monitoring of drop impact damage in WGFRP composites in real-time applications.

Lean plays a major role in the industrial environment. It is a set of techniques that are used in the day to day activities of the automobile industries. More than 30 lean tools are used in the regular schedule of the production environment. Each type of organization uses a particular type of lean tool for a particular problem to achieve optimum production. In order to find the most influential lean tools based on the ranking, a survey has been conducted in 91 automobile industries. The survey is based on the 5 point likerts scale to find the highly impacted lean tools. The survey results show that around 5 tools out of 30 are highly effective. Hence, these works mainly focus on ranking of lean tools, its positive impact towards the automobile industries. It also focuses on the flexibility of tools and how these lean tools can be effectively utilized for the increase in the production rate of the manufacturing industries. © 2014 The Authors.

Industrial muda elimination is a major challenge that is faced by the experts in the day to day activities of producti systems. Mostly there are seven types of industrial muda in lean systems such as Defects, Overproduction of things demanded by actual customers, Inventories awaiting further processing or consumption, Unnecessary over-processi Unnecessary motion of employees, Unnecessary transport and handling of goods, Waiting for an upstream process to deliver, for a machine to finish processing, or for a supporting function to be completed. Every organization faces particular type of wa that occurs in day to day production activities. In order to find out the most influential lean waste based on the ranking, a surv has been conducted in 91 automobile industries based on the 5 point likerts scale to find the highly impacted lean muda. T survey results stating that 3 types of waste arising out of 7 waste which heavily affect the production system. Hence this w mainly deals with assessing the most deadly waste by ranking the major waste using the weighted average method in which ea waste is assigned a weight. Based on the results, the major muda, which are identified that affects the production activities discussed in detail and how this muda can be eliminated and incorporated with the production system are discussed. © 2014 The Authors.

Transition metal complexes of Mn(II), Fe(III), Co(II), Ni(II) and Cu(II) ions have been synthesized from cinnamaldehyde and diethylenetriamine. The complexes have been characterized by elemental analysis, molar conductance, magnetic susceptibility, FT-IR, electronic spectra, 1H NMR, 13C NMR, ESR, mass spectra and thermal studies. Their ligand field parameters have also been calculated. Hydrolysis of ethyl acetate has been studied by using the complexes as homogeneous catalysts. The DNA cleavage activities of Schiff base and its metal complexes have been monitored by agarose gel electrophoresis method in the presence of hydrogen peroxide. The antimicrobial activities of ligand and its metal complexes have been examined on the fungi Candida albicans and Aspergillus niger and bacteria Staphylococcus aureus, Escherichia coli and Bacillus cereus. © 2016, Chemical Publishing Co.

This paper is outlined with the handle time in relational query languages. The logic is based on advanced. Boolean and Comparison operators by allowing their operands to be sets of intervals. Proposed data modelling provides temporal retrieval capability using an extended logic for comparison and Boolean operators. The extended logic allows these operators to accept set of intervals and return results in the form of set of intervals. New syntax for retrieval statements is defined in order to separate the process of selecting entities (tuples relational calculas) and the process of selecting required values of temporal attributes from the chosen entities. The theme presented in this paper offer a good degree of flexibility in expressing different temporal requirements.
