Title          
 Complex Classification Using Advanced Machine...  
 
Abstract    
 In this report, we studied different complex classification models such as Gradient Descent, Multiclass Classification. We also used different Machine Learning tools such as LibSVM, MEGAm, and FastDT to design a complex classifier based on OVA and AVA approaches. We also designed 2 different Rank classifier using MEGAm library and evaluated its performance on the OHSUMED database. The binary classification accuracy (0-1) error using 20 different queries and 10 retrieved documents for each query was 33% for Ranking Classifier 1. The binary classification accuracy for Ranking Classifier 2 was 37%. However, the average ranking performance, as evaluated using DCG metric, was roughly 8% better for Ranking Classifier 2 as compared with Ranking Classifier 1. This improvement comes from the cost function used to penalize the mis-ranking.

Title          
 Technical Report  
 
Abstract    
 Refurbishment, also referred to as renovation is the process of renewing or restoring a building to a new or former condition and consists of major or minor repair and maintenance works. The purpose of this paper is to put forward a proposal document for total refurbishment scheme of Salvation Army citadel building in Sheffield, UK to modern day standard. The report is divided into eight sections to analyse, review and recommend an appropriate procurement strategy and contract form for the historic building. It discusses the various procurement strategy methods and legal forms of contract and recommends the one which is most appropriate for the proposed project. The estimated costs for refurbishment, value engineering methods, suitable form of tender documents and top ten risks that can affect the success of the project are also reviewed.

Title          
 Modeling and Simulation of Mixing Layer Flows...  
 
Abstract    
 Film cooling has been selected for the thermal protection of the composite nozzle extension of the J-2X engine which is currently being developed for the second stage of NASA’s next generation launch vehicle, the Ares I rocket. However,several challenges remain in order to achieve effective film cooling of the nozzle extension and to ensure its safe operation. The extreme complexity of the flow (three-dimensionalwakes, lateral flows, vorticity, and flow separation) makes predicting film cooling performance difficult. There is also a dearth of useful supersonic film cooling data available for engineers to use in engine design and a lack of maturity of CFD tools to quantitatively match supersonic film cooling data. This dissertation advances the state of the art in film cooling by presenting semi-empirical analytical models which improve the basic physical understanding and prediction of the effects of pressure gradients, compressibility and density gradients on film cooling effectiveness. These models are shown to correlate most experimental data well and to resolve several conflicts in the open literature. The core-to-coolant stream velocity ratio, R, and the Kays acceleration parameter, KP, are identified as the critical paramete...

Title          
 Modeling and Analysis of Globalizing Manufact...  
 
Abstract    
 The work undertaken in the dissertation is of pioneering nature integrating world databases to accrue knowledge about economies and enterprises around the globe. It is an endeavor to demonstrate the adequacy of applying data mining techniques in global databases concealing heaps of knowledge about enterprises engaged in manufacturing and exporting in the global context. A cohesive and coherent exploration of databases from repositories of World Bank, GEM, WEF and IFC’s Enterprise Survey elucidates the patterns of internationalization of enterprises through manufacturing exports in developed and developing economies. We have followed inductive reasoning methodology using symbiosis of statistical modeling and data mining coupled with extensive data visualizations.The exploratory research has asserted the fitness of manufacturing exports as the core engine for economic health of a country. Both Kruskal-Wallis and Chi-square tests affirm that manufacturing export share level is not independent of economy type and, developed economy block shares 77% of world manufacturing exports matching to their share in world GDP. Manufacturing exports per capita for world five economies ranks them exactly analogous to their inco...

Title          
 Computational Support for the Collaborative D...  
 
Abstract    
 This thesis discusses the use of a cooperative, agent-based search in the cable harness routing problem (CHRP). They hypothesis behind this work is that a human designer can be greatly assisted in the intricate task of routing cables through a complex space if he is empowered to interact naturally with other autonomous agents as well as with the design itself. A collection of automated search and routing agents, which make use of domain knowledge and which are able to communicate with the human designer, is discussed. In addition, this thesis presents a novel interactive routing environment in which each agent is able to communicate design fragments with others via an adaptive, genetic-based blackboard.

Title          
 Decline of the Tip-Jet  
 
Abstract    
 One way to power a helicopter rotor is to blow air through the rotor tip. Such helicopters are known as tip-jets and have the potential to be lighter and simpler than conventional helicopters. Tip-jets were widely studied in the 1950s but have not seen production due to low efficiency and very high noise levels. However, based on historical data, a compound configuration which uses tip-jet power only during vertical take-off and landing, and then transitions to an autogiro mode using a propeller for forward thrust has the potential to provide fast, efficient, and reliable flight characteristics, while minimizing noise levels to those encountered in conventional rotorcraft.

Title          
  A Machine Learning approach to localization ...  
 
Abstract    
 Many sensor network related applications require precise knowledge of the location of constituent nodes. In these applications,it is desirable for the wireless nodes to be able to autonomously determine their locations before they start sensing and transmitting data. Most existing localization algorithms rely on anchor nodes whose locations are known to determine the positions of the remaining nodes using methods such as triangulation or trilateration. In this work, we consider the scenario where anchor nodes are not equipped with any self-positioning functionality, and do not have the knowledge about their positions. In such cases, anchor nodes respond to a "HELLO" signal transmitted by the localizing node. The response to "HELLO" signal can be used by the localizing node to estimate the time of arrival (ToA) or Received Signal Strength Indicator (RSSI). We use such ToA or RSSI measurements to learn node locations using Support Vector Machines (SVM). We cast the problem into a regression and a multiclass classification setting, and demonstrate the high localization accuracy achieve by this approach as compared with the traditional Least Squares based solution. We also demonstrate that strategically choosing the evaluation order o...

Title          
 Integrated Approach to Value Management and S...  
 
Abstract    
 This research has investigated the current situation of Value Management (VM) and Sustainable Construction (SC) in the Indian construction industry with respect to various aspects such as client’s attitude towards the subject, barriers posed to implementation, its application in the construction industry, identification of gaps and overcoming the barriers and establishing the amount of knowledge of people about both the subjects, who work in the construction industry. It has also defined the principles of Sustainable Construction in three dimensions: environmental, economic and social.
The research findings have revealed that SC principles are not a major consideration in the Indian construction industry and many people who work in the Indian construction sector have little or no experience in sustainable development. On the contrary, VM has been in practice in the Indian construction industry for more than four decades and its application is mandatory in all governmental projects funded by Indian government. Hence, VM practitioners possess great experience, skills and knowledge. However, there are a number of barriers that could affect the VM performance in the Indian construction industry which are taken into account in t...

Title          
 Business Plan for Online Money Transfer  
 
Abstract    
 This is a detailed business plan proposing an online money transfer system, very similar to what PayPal is today, that we proposed to a panel of Indian VCs in 2001 but was not funded on assumptions that Reserve Bank of India will not allow such radically different money transfer methods to be implemented. The plan, proposed at the same time when PayPal was also just getting started, allowed online transfer of money, virtual cash and micro payments, .
