Piezo-electric Power Scavenging for Mining Applications (ECE/EEE Project)

The growing need of creating a network of sensors in critical environment to monitor, sense and alert an operator about the environment gives rise to the research work carried out in the area of power supply to these sensors.

Wireless sensors are usually designed to run on batteries. However, as the number of sensors increases and the devices decrease in size, there is clearly a need to explore alternatives to battery power for wireless sensors. Reliable, efficient and environmentally friendly energy harvesting methods could be adopted to design and build a new electronic device that could be used to replace or supplement batteries in wireless sensors.

This thesis focuses on potential ambient sources of power that can be harvested to run low power wireless sensors in mining environments. It discusses several techniques for converting energy from such sources into useful electrical power. In particular, piezoelectric power conversion technique is described in detail.

Wireless sensor or sensor networks hold significant potential in the mining environment. The need for deployment of such sensor networks is increasing daily as mining companies are looking to adopt the system developed in the “Intelligent Mine – Technology Program (IMTP)”. The objectives of the IMTP are to increase the mine’s productivity, decrease the total costs and to improve the working conditions. To complement these objectives, there have to be improved methods for powering sensor devices to deploy them in large numbers.

Drilling is a crucial component in both underground and surface mining. Water jet assisted drilling is an example of a new drilling technology employing wireless sensors. There are various forms of energy that could potentially be used to power wireless electronic sensors provided the waste energy can be tapped in an intrinsically safe way. In this particular project, the required power to run sensors could be generated by converting mechanical vibration produced from water jet assisted drilling into electrical energy with an intrinsically safe circuit. Various power scavenging methods were researched, but vibration-to-electricity conversion using piezo-ceramic material was selected as the most promising method for this project.

Piezo-based energy conversion is not normally good for mining applications because of intrinsic safety issues. In the case of water jet assisted drilling, however, the environment is much more suitable for piezo-electric conversion. A detailed computer model for this type of power conversion has been developed. The mechanical model of the vibration spectrum is based on test data from the Contents 2 CRC-Mining group. A power conversion circuit has been built, detailed circuit simulations studied and the experimental results are demonstrated.

An example vibration scenario consisting of (20×10^-6)rms strain is considered. Based on this, and a detailed model of a 70mmx25mm PZT piezoelectric patch with 0:2mm thickness, our computer simulation studies and experiments demonstrate the ability to harvest up to 210mW of power.

Nonlinear Constrained Component Optimization of a Plug-in Hybrid Electric Vehicle (Mechanical Project)

Today transportation is one of the rapidly evolving technologies in the world. With the stringent mandatory emission regulations and high fuel prices, researchers and manufacturers are ever increasingly pushed to the frontiers of research in pursuit of alternative propulsion systems. Electrically propelled vehicles are one of the most promising solutions among all the other alternatives, as far as; reliability, availability, feasibility and safety issues are concerned.

However, the shortcomings of a fully electric vehicle in fulfilling all performance requirements make the electrification of the conventional engine powered vehicles in the form of a plug-in hybrid electric vehicle (PHEV) the most feasible propulsion systems. The optimal combination of the properly sized components such as internal combustion engine, electric motor, energy storage unit are crucial for the vehicle to meet the performance requirements, improve fuel efficiency, reduce emissions, and cost effectiveness.

In this thesis an application of Particle Swarm Optimization (PSO) approach to optimally size the vehicle powertrain components (e.g. engine power, electric motor power, and battery energy capacity) while meeting all the critical performance requirements, such as acceleration, grade and maximum speed is studied. Compared to conventional optimization methods, PSO handles the nonlinear constrained optimization problems more efficiently and precisely. The PHEV powertrain configuration with the determined sizes of the components has been used in a new vehicle model in PSAT (Powertrain System Analysis Toolkit) platform. The simulation results show that with the optimized component sizes of the PHEV vehicle (via PSO), the performance and the fuel efficiency of the vehicle are significantly improved.

The optimal solution of the component sizes found in this research increased the performance and the fuel efficiency of the vehicle. Furthermore, after reaching the desired values of the component sizes that meet all the performance requirements, the overall emission of hazardous pollutants from the PHEV powertrain is included in the optimization problem in order to obtain updated PHEV component sizes that would also meet additional design specifications and requirements.

A Study on Retail Management with Big Bazaar (MBA Project)

 

 Introduction to Retailing:

“Retailing is a distinct, diverse and dynamic sector” . “It is an activity of enormous economic significance to most developed nations”. It generates revenue and wealth for nation, encourages investments and brings technological advancements. Stated that “it brings employment and creates wealth of the economy”. “It is a vibrant part of our changing society and a major source of employment”

Retailing performs activities at larger level so it requires massive manpower to handle and manage it’s operations. Retailing also helps society in general by providing goods and services in reasonable price and increasing their standards of living. “Retailing activity can be viewed as a significant contributor to the economy in general”.

Retailing is the set of activities that markets products or services to final consumers for their own personal or household use. It does this by organizing their availability on a relatively large scale and supplying them to consumers on a relatively small scale.” Retailing makes products and services available in large quantities. Retailers produce or order the products/services in bulk so they can take advantage of economy of scale and thus they can formulate competitive pricing strategies. Products and services are generally sold through the store or on the internet.

Introduction to Retail Industry:

The first decade of modern retail in India has been characterized by a shift from traditional kirana shops to new formats including department stores, specialty stores hypermarkets, and supermarkets and across a range of categories. Modern retail formats have mushroomed in metros and mini-metros. In the last few years, modern retail has also established its presence in the small cities, exposing residents to shopping options like never before.

Some of these stores are branded stores(exclusive showrooms either owned or franchised out by a manufacturer) , specialty stores(greater choice to consumer, comparison between brands is possible) , department stores/supermarkets (one stop shop catering to varied consumer needs) , hyper-mart (low prices , vast choice available including services such as cafeterias.) , shopping malls (variety of shops available to each other ).

Teaching Interview Skills To Remember

Teacher job interviews are the point at which all of our ambitions to a certain job come together and crystallize in one place, where we can give the performance of our life and emerge with the job, or fail to really get going and end up without the job. Our teacher interview answers need work if we are to ensure ourselves a shot at the job which, in many cases, we have dreamed of doing since we were very young. Honing your abilities is necessary before such time as you walk into a teaching job interview, and the best way to hone your teaching interview skills is to practice before the big day arrives.

The Most Important Teaching Interview Skills

It is essential to remember that getting a teaching job relies on your entire recruitment process being as good as it can be, from training through application to interview. Without a decent resume and covering letter it is hard to get a secondary teaching interview, and even if you do the best teaching interview skills imaginable will not get you the job if someone else performs equally well. But there are definitely things you can work on to make sure your answers to teacher interview questions put you in the forefront of the interviewers’ minds. Making sure you have the key teaching interview skills covered will give you the best chance of winning the job.

Your teaching interview skills plan should involve making sure you are at your best in terms of:

Explaining Yourself. If you can convince the panel that you are worth considering – not by telling them, but by showing evidence in your personal qualities that you are – then you stand a good chance. If you can make a persuasive case that you know how to communicate, they’ll believe you can do the same in a classroom. This is where teaching skills and teaching interview skills meet.

Recovery. We’ve all been in a situation where we are under scrutiny, and made a mistake. We’re human, and humans make errors no matter the preparation – that’s nothing to be ashamed of. It is how you respond to the error that really matters. One of the most important teaching interview skills is your recovery abilities. Having made a little faux pas in a teaching interview, can you turn it around and while acknowledging the mistake show that it hasn’t cowed you?

Presentation. Presentation in an interview does not just come down to your suit being ironed and your hair being brushed – although it certainly helps. One of the best interview tips for teachers is as follows: presentation is also in how you answer a question, how you speak, smile and make eye contact. The interview panel will be looking to visualize you in front of a class. Make it easier by using your teaching interview skills to look like a teacher.

Humility. You don’t have to show pathetic levels of gratitude for the fact that the interview panel have deigned to invite you to their Art teacher interview. What you do need to do is demonstrate a knowledge of the fact that you aren’t perfect – but are aware that you would be an asset. One of the key teaching interview skills is the ability to appear confident without appearing arrogant.

These are just some of the major teaching interview skills that will help you get the job. There are others, but these four are an excellent place to start.

Q-Learning for Robot Control (Robotics Project)

Q-Learning is a method for solving reinforcement learning problems. Reinforcement learning problems require improvement of behaviour based on received rewards. Q-Learning has the potential to reduce robot programming effort and increase the range of robot abilities.

However, most current Q-learning systems are not suitable for robotics problems: they treat continuous variables, for example speeds or positions, as discretised values. Discretisation does not allow smooth control and does not fully exploit sensed information. A practical algorithm must also cope with real-time constraints, sensing and actuation delays, and incorrect sensor data.

This research describes an algorithm that deals with continuous state and action variables without discretising. The algorithm is evaluated with vision-based mobile robot and active head gaze control tasks. As well as learning the basic control tasks, the algorithm learns to compensate for delays in sensing and actuation by predicting the behaviour of its environment. Although the learned dynamic model is implicit in the controller, it is possible to extract some aspects of the model. The extracted models are compared to theoretically derived models of environment behaviour.

The difficulty of working with robots motivates development of methods that reduce experimentation time. This research exploits Q-learning’s ability to learn by passively observing the robot’s actions—rather than necessarily controlling the robot. This is a valuable tool for shortening the duration of learning experiments.

Reinsurance: Insurance to Insurers (MBA Finance Project)

Reinsurance is a means by which an insurance company can protect itself against the risk of losses with other insurance companies. Individuals and corporations obtain insurance policies to provide protection for various risks (hurricanes, earthquakes, lawsuits, collisions, sickness and death, etc.). Reinsurers, in turn, provide insurance to insurance companies.
Reinsurance helps primary insurers to reduce their capital costs and raise their underwriting capacity since major risks are transferred to reinsurers’’; the primary insurer no longer needs to retain capital on its balance sheet to cover them. Reinsurance thus serves the primary insurer as an equity substitute and provides additional underwriting capacity. This indirect capital is cheaper for the primary insurer than borrowing equity, since reinsurers can offer to assume risks at more favorable rates thanks to their superior risk diversification.

The additional underwriting capacity permits the primary insurers to assume additional risks which without reinsurance they would either have to refuse or which would compel them to provide a lot more of their own capital. In a globalized world, in which potential financial claims are steadily rising and in which the limits of insurability are being constantly extended, reinsurance thus assumes a major significance for the whole economy.

The reuse of Design rules by Product and Process documentation – A descriptive case study (Mechanical Project)

The problem of automating design processes is often related to the difficulties with updating, maintaining and sharing the information. This thesis provides a descriptive case study of a large company’s design automation process and the difficulties of reusing already existing solutions.
The main purpose of the thesis has been to trace a product family from its specification of demands to a complete design program. An account is given of the documentation written during the product development process, of the different data storage and also how the company has implemented design automation in their process.

The results have been reached through a series of interviews as well as previous studies and material from the company. From an analysis of the results proposed solutions are given and focus on the low quality the documentation has and how it is a result of a rapid growth within the company.

RETINA: A Real TIme Navigation System (Computer Project)

Mobile computing systems are playing a more and more important role in everyday life and applications based on both local and wide area distributed wireless networks are being launched all the time. One of the more challenging applications is real-time traffic navigation, and this thesis focuses on our experience in the design and implementation of a REal-Time Traffic Navigation System (RETINA).

There are a large number of challenging issues involved in designing a system that can support navigation requests and meet the arrival deadlines. These include the management of real-time traffic data, the execution of navigation requests and the monitoring of the best paths for these requests. Focusing on minimizing the probability of missing arrival deadlines as well as reducing the overhead for monitoring the best path, a replicated directed graph approach for searching the best path in which the servers cache traffic data from other servers is proposed. Since the accuracy of this approach depends on the currency of the cached traffic data, a number of approaches for refreshing this data are explored and an adaptive push and pull technique is proposed.

RETINA was implemented using two basic components: database servers and mobile clients. The server program is implemented in VC++ 6.0 on Windows NT and the 2 client program is implemented using both VC++ 5.0 for Win CE 3.0 and VC++ 5.0 on Windows 2000. The server process consists of multiple flags for different functions including servicing requests from mobile client and for system management. A SQL server is connected to the server program at each site and it maintains a database containing the road connections of a district in Hong Kong. A simulated process is defined at the server to create new traffic data values randomly for the road segments maintained by the system. Each client machine, PC or handheld PC, is pre-loaded with a set of maps for the roads defined in the database servers. The client program supports search for best paths, as well as a number of location-dependent requests.

In addition, a number of simulation experiments were used to explore the effect of various parameters such as push threshold and traffic update rate on the effectiveness of the various proposed mechanisms such as adaptive push and pull. The results show that our algorithms do perform well for various operating environments.
