Design and Analysis of Flexible Power Electronic Transformer
Conventional transformers made of copper and iron are one of the most costly and heavy device in electrical system. The conventional transformers are suffering from the drawbacks like they are heavy and bulky, sensitive to harmonics, voltage drop under load condition and concerns regarding mineral oil. To overcome these drawbacks new power electronic based transformers are developed. Many drawbacks of conventional transformer have been removed by Power Electronic Transformer (PET). Still PETs are suffering from drawbacks like less effective for power quality improvement, bidirectional power flow is not possible, not expandable to achieve higher ratings and independent operation of ports are not possible. A new topology of Power Electronic Transformer (PET) can be developed consisting of multiple port to get much flexibility in terms of applications. This project proposes a new Flexible Power Electronic Transformer (FPET). Design of FPET is done based on modules and a common dc link for all the ports. Each module made of three parts, modulator (inverter/rectier), demodulator (cycloconverter) and High Frequency Isolation Transformer (HFIT).

Picture Compression Issues Relating to Digital Television
Digital image compression is essential. Digital storage of movies may not be possible without this.Improving of Telivision is required for transmission of high data rates. Advanced Digital television for terrestial modelling is a focus.However, too fundamental concepts were removed.Sample results are retained rather of entering all for the sake of compactness. One may say that inclusion of image processing and optical communications techniques were used where ever necessary.

Efficiency of Fluorescent Whitening Agents in Pigment Coatings
This work is strongly recommended to those who are working to find out the best possible amount and place of Fluorescent Whitening Agents (FWA) to be used in pigment coating for the enhancement of paper sheet appearance. It concludes that the brightness and whiteness can be improved by using the higher amount of FWA in the top coating rather than in the first coating. Furthermore, the colouring shades improve the brightness and whiteness by the addition in both the substrates and the coating layer as well.

Applications of Ferroxane Nano Structures for Removal of Heavy Metals
In this book, lead adsorption efficiency of carboxylate-ferroxane nano structures from aqueous solutions have been studied. FTIR, SEM and DLS analysis characterized the synthesized samples. Performance evaluation of nano particles and nano composite in adsorption process was achieved using Taguchi and Box-Behnken experimental designs. Variables in adsorption process were initial pH, contact time, adsorbent dose and initial concentration of Pb(II) ions. Adsorption of lead was performed through two possible mechanisms; ion exchange and complex formation in case of both, the nano particles and the nano composite. Para amino benzoate-ferroxane nano particles performed the best among the other nano particles studied in lead adsorption. Also its corresponding nano composite with chitosan showed an improvement in Pb(II) uptake in comparison with the pure chitosan film.

Development of Refractories from Local Kaolin
Refractories are materials that can withstand high temperatures and chemical attack of slags without failing, they can be classified as acid, basic or neutral; some are also referred to as special refractories; these are very expensive materials, such as zirconia reserved for research purposes (Gilchrist,1977).They are thermal insulators which are used essentially in the metallurgical industries for furnace linings, kilns, nozzles for pouring molten metal, heat exchangers and driers, to mention a few (Hassan, 2001 and Guo, 2004). Refractory materials are extensively used in the metal industries, along with glass melting and other heat treatment operations. The atmosphere in which a refractory is to operate can dictate the materials that can be used in particular applications; for example, graphite refractories can operate at temperatures of up to several thousand degrees celsius under reducing conditions, or oxygen free conditions, such as vacuum. The type of materials that a refractory comes into contact with can also dictate which material will be suitable for a particular refractory purpose.

A Receptionist Robot: Interface and Coordination
This book presents a project that consists on the development of a receptionist robot for the Institute for Systems and Robotics (ISR), Lisbon. This robot is stationed at ISR's lobby, where it waits for nearby visitors. At this point it attempts to interact with them in order to find out whether they wish to be lead to a specific room on this floor. The followed development methodology focuses on the integration of several modules, featuring navigation and localization capabilities, a graphical interface, speech recognition and synthesis, people detection, face detection, and behavior control, in order to achieve an autonomous system. In order to save time and effort, as well as obtaining a robust solution, "off-the-shelf" software packages are used whenever possible. The present theses focuses, apart from the conception of the robot's hardware and software architecture design, on its human-robot interaction capabilities, as well as on the integration and coordination among all modules.

The key idea is to identify the displacement of anatomical landmarks relative to local coordinate frame defined by skin markers in a pre-specified motions and build a regression model between the two displacements of anatomical landmarks and skin markers relative to local coordinate frame. The performance of the method was compared with the related previous methods.

The Efficiency of Local Bentonite as an Extender in Well Cementation
Nigerian local Bentonite has been in use since 2003, but has not gained wide acceptance in the petroleum industry because of its effects on most of the cement properties. However, these effects have not been properly studied and modeled. This study involved the experimental and economic evaluation of some Nigerian local bentonite on fresh and salt water cement slurry properties. These properties were compared with those of the more traditional foreign bentonite.The Nigerian bentonite was beneficiated because of its natural state. Both bentonite proved effective in fresh water cement slurries and can mostly be used interchangeably except in cases where high rheology are required. For salt water slurry design local bentonite proved to respond better in rheology and free fluid test evaluation. Therefore, with proper beneficiation and further research, Nigerian local bentonite could be more efficient and cost effective as an extender in cement slurries.

Robust Design in Structural Engineering
Robustness has recently become a popular term in structural and hydraulic engineering. However, the concept of 'robust design' or 'robustness' has no clear definition. The aim of this work was to find a definition for a robust system and to use this definition to search for an added value of robust design in structural engineering. The literature on robust design has been extensively studied to es-tablish a definition for a robust system. It was concluded that a robust system can be found by as-suming that the additional risk that arises due to discrepancies between the reality and the model, is smaller for a robust system than for a less robust system. When designing a system, it is however al-ways the priority to find a cost-optimal design alternative. In other words, economic optimization has priority over robustness. The reason for this it that robustness focuses on hazards for which no value of the risk can be defined, so that it cannot be quantified what may be spent on robustness. In this thesis, the meaning of a robust system was tested in several case studies. From the case studies it as investigated when and why robustness can be of added value.
