Plefka's mean-field theory and belief networks
Mean-field theory is an interesting alternative to Markov Chain Monte Carlo techniques for probabilistic inference in graphical models. In this thesis, we study a powerful mean-field technique proposed by Plefka, in the ... -
Galois field Computations : Implementation of a Library and a study of the Discrete Logarithm Problem
Computation over finite fields (also called Galois fields) is an active area of research in number theory and algebra, and finds many applications in cryptography, error control coding, and combinatorial design. In this ... -
Facets of some combinatorial polytopes
A proven approach for solving hard combinatorial optimization problems is via polyhedral methods applied to integer programming formulations. Efficient algorithms for such problems are often problem specific and exploit ... -
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 ... -
Escape mechanism in bistable systems driven by strongly correlated noise
This thesis focuses on the analysis of nonlinear dynamical systems influenced by colored noise, which appears in diverse fields such as physics, chemistry, natural sciences, and engineering. The core problem involves solving ... -
Studies on parsing, syntax directed translation and conditional grammars
The compilation process for programming langtiages in digital computers essentially consists of the following two steps; i. Translation of the source language, and ii. The generation of machine code-. The first step ... -
Scalable Distributed Frameworks for Temporal Analysis and Partitioning of Streaming Graphs
The analysis of graph-structured data has become increasingly important as networks in various domains, including science, engineering, and business, grow in size, complexity, and dynamism. While static graph analysis ... -
Thermopower probing the effect of interaction and strong correlation in twisted multilayer graphene moir´e
Two-dimensional quantum materials, especially graphene-based van der Waals heterostructures, have been at the forefront of a new era in scientific research and technological breakthroughs. From field-effect transistors to ... -
Dynamic hybrid partitioned non partitioned queue configurations based on workloads in supercomputer systems
Supercomputers rely on batch queues to manage parallel job execution, with commercial schedulers offering configurable parameters that influence job routing, execution order, and queue visitation. However, selecting an ... -
Efficient parallel algorithms to compute A sub-complex of the weighted delaunay triangulation for molecular data
In the field of bio-molecules, it is utmost important to study the behaviour of a molecule while interacting with another. This interaction decides the functionality of the molecule. It is widely accepted fact that the ... -
Efficient quantum dynamics simulations for periodic potentials
Quantum algorithms are designed to efficiently solve many problems that are thought to be difficult classically. A specific case is the efficient simulation of time evolution of quantum systems. This work provides a ... -
Some Algebraic Aspects Of Graph Similarity Algorithms
We proposed singular values-based sensitivity analysis and self-similarity studies to compare graph-isomorphism algorithms. SimRank method is found to be an application of power method and is not sensitive to noise in any ... -
Signal Processing Algorithms for Next-Generation Wireless Systems: Reconfigurable Intelligent Surfaces and Integrated Sensing and Communications
Next-generation wireless systems aim to revolutionize communication by achieving data rates up to terabits per second while also supporting diverse applications such as autonomous mobility, industrial automation, and ... -
Exploring Scalable Material Strategies Towards the Practical Metal-Sulfur Batteries
Lithium-ion batteries (LIBs) dominate the market of portable electronic devices and currently serve as the stand-alone power source for electric vehicles. LiBs are approaching their theoretical energy density limit, ... -
Secure Auctions with Rational Parties
Sealed bid auctions are used to allocate a resource among a set of interested parties. Traditionally, auctions need the presence of a trusted auctioneer to whom the bidders provide their private bid values. Existence of ... -
Understanding the Mechanism of DNA Double-Strand Break (DSB) Repair in Mitochondria and Various Mammalian Organs.
Various exogenous and endogenous agents can damage DNA. Exogenous agents include chemicals and radiation, such as ionizing radiations and UV rays, while endogenous agents include DNA replication errors, reactive oxygen ... -
Asynchronous distributed rate control algorithms for best-effort sessions in integrated services networks with minimum rate guarantees
Packet switching networks provide a best-effort transport service that is typically used by store-and-forward applications, such as email, file transfer, and web browsing. In an Integrated Services Packet Network, the ... -
Performance of multiaccess dual slotted unidirectional bus networks
Advances in optical fibre transmission system technology 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 ... -
Linguistic anlaysis of stuttering patterns among monolinguals and bilinguals
It is concluded from this study that stuttering is influenced by two major factors: phonetic factors and factors associated with the encoding process of speech. The results also support Bloodstein's anticipatory struggle ... -
Application of exponential power estimator for speech coding
In speech coding, it is known that the Differential Pulse Code Modulation (DPCM) schemes lead to the reduction of bandwidth requirement (by removing the redundancy) as compared to pulse Code Modulation (PCM) schemes, ...
