Bond Graph Modeling and Control of Induction Motor used in Ladle Cranes

Initially when power is supplied, induction motor runs at its rated speed with the recommended specifications and varying applications. Control of the motorrsquo;s speed with the improvement of the induction motorrsquo;s dynamic and steady state characteristics which are non-linear in nature, has been possible due to the advancement of electronics. The popularity of this motor has resulted into lot of research including the transient behavior of the motor. A methodology based on modeling capabilities along with control and its computer simulation has been proposed in this paper and is represented by dynamic modeling of three-phase four pole induction motor. When physical modeling of systems is necessary the bond graph approach is good, again it is also a good tool for combining different energy domains. Dependencies between different components can easily be found through the method of bond graph. This study was conducted on the basis of parameters collected from different ladle cranes motors of Durgapur Steel Plant in India

Use of Artificial Neural Network for pre Design Cost Estimation of Building Projects

The motive of this study is to apply Artificial neural network (ANN) for pre design cost estimation of building projects to investigate and overcome problems of cost estimation at initial stages of building construction. And develop & test a Graphical User Interface (GUI) model of cost estimating for reinforced concrete buildings in the early design phase. An ANN GUI model can help the designers in taking decisions about implementation of the project at the initial phases of the design process

Study on Value Engineering in Construction Projects

Value engineering is a technique by which we get to know how the cost of the project can be optimized without affecting the quality, requirements, function of the particular project. This paper tells us about the various factors which affect value engineering technique, the problem areas in the construction of buildings and also about the importance of application of value engineering to construction projects. Value engineering is a proven technique and the need of the current era

Building Information Modeling in Commercial Construction Projects

This paper explains the scope of Building information modeling in commercial construction projects, various studies performed by different researchers, background of building information modeling, data requirement and its flow between different parties involved in construction process and the various advantages and limitations of building information modeling in commercial construction projects

Study on Total Quality Management and Reward (TQMR)

As the whole world is becoming an extended community with the free trade movements of the products and services across the countries and as a result the Indian consumers too is getting exposed to the International best standard practices and products, the same also goes true when it comes to the products of the construction industries like Infrastructure, Buildings and other projects. Total Quality Management (TQM) can be answers to the quality requirements of developing nations like India. The India construction companies can adopt the TQM tools and techniques to involve every activity and everyone associated with the project to produce world class project

Estimation of Finantial Ratio Analysis between Different Selective Construction Companies in Pune

This paper is about financial management of construction companies by using financial ratios. The focus of financial analysis is on key figure in the financial statements and the significant relationship that exist between them. The analysis of financial statements is a process of evaluating the relationship between component parts of financial statement to obtain a better understanding of the firm’s position and performance. The first task of the financial analyst is to select the information relevant to the decision under consideration from the total information contained in the financial statements. The second step is to arrange the information in a way to highlight significant relationship. The final step is interpretation and drawing of inferences and conclusions. In brief, financial analysis is the process of selection, relation and evaluation

Air Bearing and its Stability

Bearing are machine element that allow components to move with respect to each other. A little consideration will shows that some part of power wasted in overcoming the frictional resistance and due to the contact of surfaces large amount of wear and tear takes place between the contacted surfaces. Hence to avoid wear and tear in sliding contact bearing and to reduce frictional resistance the thin layer of fluid is introduced which is called as lubricant. Air bearing are introduced to reduce such frictional resistance and wear of sliding contact bearings. Air bearings are bearings that use a thin film of pressurized air to provide low frictional load bearing interfaces between surfaces. There is a small gap between two surfaces i.e. two surfaces do not touch. As these bearings are contact free various problems in traditional bearing like friction, wear, particulates, and lubricant handling are avoided. There are advantages like precision positioning, such as lacking backlash and static friction as well as in high speed application. Other than this characteristics, stability is also important factor in air bearing

Implementation of a Portable Learning Management System (PLMS) without Internet for Skill Development in a rural Educational Institute’s

Skill development initiatives are critical for India's advancement since they reduce unemployment, stimulate economic growth, promote inclusion, and strengthen the country's worldwide competitiveness. By investing in skill development, India can capitalize on its demographic dividend and unleash the potential of its workforce for long-term growth and prosperity. The situation of education in rural India is frequently marked by several problems, particularly when it comes to accessing technology resources such as the internet and Learning Management Systems (LMS). Rural education infrastructure is often less developed than in urban areas, resulting in limited access to new technologies and digital resources. The Present research paper focuses on design and implement portable Learning Management System (PLMS) without internet for skill development in rural education Institutes

Assessment of Procurement Parameters for A Construction Project

The Procurement of raw material and the handling equipment for the Construction works involve valid sources of supply with varying cost and other liabilities while arriving at the most effective proposal. The abvious parameters for arriving at a purchase decision are cost, lead time, quality of commodity being purchased. Typically supplier are located in a vicinity of the site through their prices could vary amongest themselves as well as the index for the quality. The distant supplier might seem economic for the price while the lead time might not justify the choice. These contrasting needs of the purchasers underline the need for optimal or balanced methods of evaluating the impact on the said resources

LAN Monitoring Using Android Phone

ABSTRACT: Now a day's android phones are used for the various applications. We can use android phone for monitor and control the network. It is to control the network when network admin is in admin office but it is difficult to control the network from outside the office. It is integrated software solution that allows a network admin to remotely monitor his LAN network by his Android phone with GUI. The main purpose of this application is to provide all the important details of the network to the admin on their android phone with the help of GPRS or Wi-Fi. We are using data connectivity or Wi-Fi to connect the mobile phone to LAN server. And we also are using password encryption for authentication in phone
