CFD Analysis of Fluid Flow in Sand Casting

In Casting process filling and solidification is difficult to visualize by experimental methods. The fluid flow, phase transfer, temperature distribution and velocity gradient is undesirable. So we are going to CFD software to control the solidification parameters. According to finite element theory, using FLUENT software and three dimensional model to simulate liquid metal free surface and temperature field of casting filling process numerically. Boundary and initial conditions, such as velocity, pressure, temperature, etc., was reasonably calculated by theoretically. The feasibility of using FLUENT to simulate three dimensional casting was stud

ied the fluctuation of molten metal free surface was observed. The temperature distribution data on the end of filling was recorded, for further numerical simulation of casting solidification process which provided an accurate initial condition.

A Study on "Radar Helmet for Soldiers"

Soldiers are very essential part of any nation's security system. During, wars and search operations soldiers get injured and some of them go missing. As we all know soldier's health is important because they are the savior of our country who protects us from terrorist attacks and from many suspicious activities which can harm us and our nation too. This project will give an ability to track the location and monitor health of the soldiers in real time which goes missing at battlefield. It will minimize the time and rescue operation efforts of army control unit. It will help the army base station to track the location and monitor health of soldiers using GPS module and sensor such as temperature sensor, heart beat sensor, etc. The data coming from sensors and GPS receiver is transmitted wirelessly using Zigbee module having the range of 10 to 100m. A soldier can ask for help from control room using a panic switch and we have also used RADAR which will alert the soldier using vibrator within the range of 3cm to 4m.

Design and Analysis of a Multiple Cutting Hacksaw Automatic Machine

A hacksaw is a fine-toothed saw, mostly utilized in reason for cutting metal. Hacksaw can likewise be utilized to cut different materials for instance plastic material PVC pipes and pipe installations and wooden materials with them. There are two sort in particular, hand saw forms and fueled variants control hacksaws . Practically every one of the hacksaws are hand saws with a C-formed edge that holds an edge under strain with the maintenance screw. Such hacksaws have a handle, normally made of a wooden grasp, with pins for appending a restricted expendable hacksaw sharp edge. The bleeding edge of a saw is either a serrated sharp edge like teethes. The casings have additionally arrangement for acclimating to oblige sharp edges having distinctive lengths. A screw or other system is utilized to put the slender edge under strain.

Analysis of Imbalanced Classification Algorithms A Perspective View

Classification of data has become an important research area. The process of classifying documents into predefined categories Unbalanced data set, a problem often found in real world application, can cause seriously negative effect on classification performance of machine learning algorithms. There have been many attempts at dealing with classification of unbalanced data sets. In this paper we present a brief review of existing solutions to the class-imbalance problem proposed both at the data and algorithmic levels. Even though a common practice to handle the problem of imbalanced data is to rebalance them artificially by oversampling and or under-sampling, some researchers proved that modified support vector machine, rough set based minority class oriented rule learning methods, cost sensitive classifier perform good on imbalanced data set. We observed that current research in imbalance data problem is moving to hybrid algorithms.

Reactive Power Compensation with Fuzzy Logic in Electrical Facilities

The inductive loads fed by the electrical installations are reflected as an additional load by pulling the reactive power from the mains. Inductive loads are an important and useful parameter in the formation of rotating field of motors, formation of magnetic field in transformers. However, it is a harmful parameter that decreases blackness in transmission and distribution lines. Therefore, in large-scale power plants, reactive power requirements are provided by compensator systems connected to the input terminals. Continuous control equipment and systems need to be developed to improve the continuity and efficiency of energy systems. 

In this study, reactive power compensation, fuzzy logic-controlled application was made. Thus, power factor correction, dynamic voltage control are provided, power transmission capacities of the transmission lines and losses caused by reactive power flow are minimized. However, the fact that this compensator system is not linear makes it difficult to mathematically model them by using system based control systems based on fuzzy logic theory. In this study, without a mathematical model of the system, a control process based on fuzzy logic applied to the result was realized by using the effective relationship between system output and input.

Performance Analysis of CIR and Path Loss Propagation Models in the Downlink of 3G Systems

This paper analyses the Carrier to Interference Ratio CIR and path Loss PL variation in downlink 3G FDD-UMTS mobile system. The evaluation was taken in urban, suburban and rural environments. Also, frequency band of 2110 Hz is used in this work. The received CIR analysis is based on comparative study of seven Path Loss propagation models COST- 231 Hata, COST-231 WIM Walfisch-Ikegami Model , SUI Stanford University Interim , FSM Free Space Model , PSM Standard propagation model , Ecricsson and ECC33 Electronic Communication Committee . Simulation results show that SUI and SPM models showed the lowest Path Loss for all environments. Also, we can show that received CIR is affected not only by the geometry of the UMTS base station location but also by the number of users presented in each cell.

Multi-Response Parameter Optimization Hardness and Unevenness Effect of Hardox Cutting Plate by High Tolerance Plasma Arc Cutting System

High Tolerance Plasma Arc Cutting System 12mm plate thickness Hardox has been cut by high tolerance plasma arc cutting machine and the unevenness of cutting has been investigated. According to the experimental results, it has been seen that burning of particulars and distribution amount were increased when the cutting was performed measured the speeds. Moreover, it has been noticed that the change the speed which affects the cutting width of plate also change the unevenness of plate with cutting speed. in this study is that quality of the cut can be improved by means of a proper selection of cutting speed . The aim is to see how the cutting system and speed affect material structure up to what depth, it was determined that the hardness from the outer surface to the core decreased, while the hardness near to the outer surface which affected by the high temperature occurred during cutting increased.
