Algorithms for coloring random and semi-random graphs
The graph coloring problem is NP-hard and arises in a variety of practical situations. Recent breakthroughs in the area of approximation complexity indicate that it is not possible (unless P = NP) even to approximate the ... -
Application of trust region on methods to learning in feed forward neural networks
This thesis presents a novel algorithm for training feed-forward neural networks, addressing the limitations of the widely used back-propagation and Quickprop algorithms. While Quickprop is significantly faster than standard ... -
Clustering For Designing Error Correcting Codes
(Indian Institute of Science, 2005-02-11)In this thesis we address the problem of designing codes for specific applications. To do so we make use of the relationship between clusters and codes. Designing a block code over any finite dimensional space may be thought ... -
Diffraction Tomographic Imaging With A Circular Array
(Indian Institute of Science, 2005-06-02)In the conventional diffraction tomography a linear array is used to receive forward scattered field. Then a standard algorithm like back propagation or Fourier domain interpolation is used for reconstruction of the object. ... -
Dynamic Channel Allocation for integrated Voice Data Communication A Tdm Approach
Integrated Services Digital Network (ISDN) is an extension of conventional telecommunications and the data trafics like text, facsimile, image. Efficient transmission of voice/data on a common communication channel has ... -
Electrical Properties Of Diamond Like Carbon Films In Metal-Carbon-Silicon (MCS) Structure
(Indian Institute of Science, 2006-01-18)Amorphous carbon film with Diamond like properties is the subject of intense interest in the past one and half decade. The unusual properties of these diamond like carbon films arise from the preponderance of SP3 tetrahedral ... -
Electronic Access Control Systems: A New Approach
(Indian Institute of Science, 2006-08-30)Security systems are gaining increasing importance in recent times to protect life and valuable resources. Many advanced methods of providing security have been developed and are in use in the last few decades. Of these, ... -
Essays in applied combinatorics
Combinatorial mathematics concerns itself with the study of discrete structures and relations. It plays a crucial role in computer science, since digital computers manipulate discrete, finite objects. The study of algorithms, ... -
Fault tolerance in feedforward neural networks using minimax optimization
Neural computing is currently being proposed as a viable solution to several problems. The approach of neural computing is to capture the guiding principles that underlie the functioning of the human brain and apply them ... -
FIR System Identification Using Higher Order Cumulants -A Generalized Approach
(Indian Institute of Science, 2010-01-12)The thesis presents algorithms based on a linear algebraic solution for the identification of the parameters of the FIR system using only higher order statistics when only the output of the system corrupted by additive ... -
Frames as abstractions for efficient multimedia object retrieval
Multimedia Information Systems (MMISs) integrate various media types - text, audio, video, graphics, and animation - for machine-processable storage, retrieval, and presentation. These systems are characterized by complex ... -
Framework for solving vehicle scheduling problems using AI techniques
Transportation resource scheduling problems are of high academic as well as practical value. These are primarily concerned with generation of movement schedules for a set of vehicles (tankers, aircraft, etc) to distribute ... -
Hypercube variant interconnection networks
The attractive properties of the hypercube have made it a popular interconnection network topology for the design of multicomputers. Researchers have been modifying the hypercube topology in subtle ways to improve upon a ... -
Interaction paradigms for distributed object-oriented programming
Current trends in large-scale distributed programming on a network of workstations are experiencing a paradigm shift into object-orientation. This is primarily driven by the need for modular, compact, portable and reusable ... -
Multi-scale approaches to signal deblurring and reconstruction from zero-crossings
This thesis addresses two inverse problems in computer vision: Solving a class of ill-posed convolution equations We analyze the problem of deblurring a Gaussian-blurred signal, which belongs to the class of ill-posed ... -
Non-Invasive Microwave Hyperthermia
(Indian Institute of Science, 2006-01-18)Presented in this thesis are the following theoretical investigations carried out on the non-invasive microwave hyperthermia of malignant tumours in the human body: Fundamental concepts of electromagnetic wave ... -
Optimal control for queue length fairness in dual bus networks
Advances in optical fibre transmission have created interest in a class of multiple access local and metropolitan area networks called unidirectional bus networks. In the absence of medium access control, the nodes closer ... -
Optimized neural network dichotomizer for speech recognition
Among the various neural network architectures and learning algorithms that have emerged recently, multilayer perceptron (MLP) network using backpropagation learning is found most effective for speech recognition due to ...
