Solving Intuitionistic Fuzzy Maximal Flow Problem Using IntuitionisticTrapezoidal Fuzzy Number
Author(s): P.Jayagowri, T.Suba
Amit Kumar and Manjot Kaur proposed a new algorithm to find the fuzzy maximal flow between source and sink by representing the flow as normal trapezoidal fuzzy numbers. There are several papers in the literature in which generalized fuzzy numbers are used for solving real life problems. But in this paper we introduced new algorithm to find the intuitionistic fuzzy maximal flow between source and sink by representing the flow as normal intuitionistic trapezoidal fuzzy numbers. To illustrate the new algorithm a numerical example is solved. If there is no vagueness about the flow between source and sink then the proposed algorithm gives the same result as in crisp maximal flow problems.

Extraction of Alumina from Local Clays Using Hydrochloric Acid
Author(s): Eze,J.U., Anyakwo,C.S., Osoka,E.C., Nnodum,A.N., Onuoha,C., Anusi,M.O
The present work investigates the extraction of alumina from different local clay samples; Ihiala clay (sample A), Nsu clay (sample B), and Umuhu clay (sample C), which contain 27.83%, 29.93%, and 28.31% of Al2O3 respectively and are extremely abundant in the Eastern part of Nigeria. The clay samples were crushed, ground and sieved using 100 mesh standard tyler screens and were further calcined at a temperature of 7000C, held for 1hr and then leached with 5ml of concentrated hydrochloric acid at different leaching temperatures (250C,500C,750C, 1000C) and time (10,30,60,80,100 and 120mins). A relatively large increase in percentage extraction of Al2O3 was also observed with increasing leaching temperature in the range of 250C to 1000C. The effects of the leaching time and temperatures were investigated using response surface methodology. A pure-quadratic model fit well to experimental data for the three clay samples. The surface plot revealed a linear relationship with temperature, which had more effect of percentage alumina extracted, and a quadratic relationship with time. An estimated optimum extraction condition for the three clay samples would be a leaching time of 76minutes and temperature of 100OC. The optimization also indicated that increasing temperature will increase percentage of alumina extracted. Leaching these local clay samples under these conditions resulted in about 81%, 79% and 79% alumina extraction for samples A, B and C respectively. The highest percent concentration was achieved with the Ihiala clay (sample A). The research therefore shows that Eastern Nigerian local clays are very suitable raw materials for the production of aluminium and other alumina based products. It is hoped that this work will help to encourage the use of our local clays as raw materials in the aluminium industries in the nearest future.

Simulation and Analysis of Distributed Power Flow Controller in High Voltage Transmission System
Author(s): Han Su Yin, Shwe Zan Aung
In power transmission systems, the power flow must be controlled quickly and reliably. As the load changes, the voltage variation in transmission lines can damage the consumer’s equipment distributed side. For reducing these problems, the power flow controller is used in transmission lines. Thus, this paper presents a power flow controlling device called Distributed Power Flow Controller (DPFC). This device offers the same control capability as the unified power-flow controller (UPFC) but with much lower cost and higher reliability. The DPFC eliminates the common DC link within the UPFC. It employs two converters i.e. series and shunt converter, and each converter needs a controlling circuit and an additional central controlling circuit which provides reference voltage to series and shunt controlling circuit. The active power that is exchanged through the common DC link in the UPFC is now transferred through the transmission line at the 3rd harmonic frequency. The interaction between the DPFC, the network and the machines are analyzed in this paper. The DPFC is modeled by using dq-frame. To simulate the dynamic performance, three phase symmetrical fault is considered near the load and, the modeling and analysis of power flow with DPFC in two areas with two buses interconnected system with star-delta transformers at each end is done by using MATLAB/ Simulink.

Modeling and Simulation of Overcurrent and Earth Fault Relay for Extra High Voltage Transmission Line
Author(s): Han Su Yin, Shwe Zan Aung
The Electrical Power System consists of many vital components. Among them, the Transmission lines are one of the most important parts of the system. Faults occur in transmission lines have high impact on the electrical power system. The major fault in transmission line is single line to ground (L-G) fault, but, various types of faults also occur in transmission line, such as unsymmetrical faults which includes single line to ground (L-G) fault, double line to ground (L-L-G) fault and line to line (L-L) fault and symmetrical faults which are three phase fault. So, the protection relays are needed to protect transmission lines from various types of faults. Overcurrent and earth fault relay is normally used to protect transmission lines, distribution lines, transformers and bus coupler etc. Moreover, these relays can be used as main or backup protection. The modeling of protection relays is required to determine the effects of network parameters and configurations on the operation of these relays. This paper presents the modeling and simulation of standard inverse definite minimum time (IDMT) relay using MATLAB/SIMULINK software. The study of test system is Paunglaung – Pyinmana High Voltage transmission line. The proposed model was tested for single line to ground (L-G) fault and three phase fault witha fault resistance (0.001 Ω)at various locations. The simulation results obtained by MATLAB software show the feasibility analysis of High Voltage Transmission Line with Overcurrent and Earth Fault relay.

Performance of Seismic Design Reinforced Concrete Building Under Different Wind Velocities
Author(s): Ei Ei Nwe, Swe Swe Khaing
The purpose of this paper is to know the performance of sixteen-storeyed reinforced concrete seismic design building with the basic wind velocity of 80 mph under five tropical cyclone categories 95,110,130,155 and 170 mph (Saffir-Simpson Hurricane Scale). In order to study the performance of selected building under different wind velocities, ETABS software is used to analyze the superstructure of the building but substructure analysis is not considered. Only four loading cases - dead load, live load, wind load and earthquake load are considered and total of twenty-six load combinations are used according to (CQHP) recommendation. Required data for analysis and design specifications of structural elements is used in accordance with UBC-97 and ACI 318-02. Equivalent static analysis is used for seismic design. Considering the effect of lateral load, Intermediate Moment Resisting Frame (IMRF) is chosen for seismic zone 2A. Firstly, the superstructure was analyzed with the basic wind velocity of 80 mph and checked by Storey Drift limitations, P-∆ effects, Torsional Irregularity, Overturning Moment and Sliding. Then, the seismic design of proposed building was repeated with five tropical cyclone categories respectively with the same seismic zone, strengths and rigidities. Similarly, they are also checked their performance. Finally, detailed comparisons are made between the analysis results such as deflection,storeydrift,storey moment andstorey shearof the structural members. It is also investigated the performance and potential deformation or damage to predict how and where the deformation could begin.

Implementation of Automated Irrigation System Using Advance Wireless Technology
Author(s): Cidgu Soundharya , Mr.V.Arun Kumar
An automated irrigation system was developed to optimize water use for agricultural crops. The system has a distributed wireless network of soil-moisture and temperature sensors placed in the root zone of the plants. In addition, a gateway unit handles sensor information, triggers actuators, and transmits data to a web application. An algorithm was developed with threshold values of temperature and soil moisture that was programmed into a microcontroller-based gateway to control water quantity. The system was powered by photovoltaic panels and had a duplex communication link based on a cellular-Internet interface that allowed for data inspection and irrigation scheduling to be programmed through a web page. The automated system was tested in a sage crop field for 136 days and water savings of up to 90% compared with traditional irrigation practices of the agricultural zone were achieved. Three replicas of the automated system have been used successfully in other places for 18 months. Because of its energy autonomy and low cost, the system has the potential to be useful in water limited geographically isolated areas.
