Generalizing Cross-domain Retrieval Algorithms
Cross-domain retrieval is an important research topic due to its wide range of applications in e-commerce, forensics etc. It addresses the data retrieval problem from a search set, when the query belongs to one domain, and ... -
Sustainable Urban Mobility: Urban Public Transport Systems Sustainability Assessment
Urban public transport systems have become an inevitable choice to promote sustainable urban mobility in almost every city in the world. In India, buses are the most popular and convenient mode of transport in urban cities. ... -
Achieving practical secure non-volatile memory system with in-Memory Integrity Verification (iMIV)
Recent commercialization of Non-Volatile Memory (NVM) technology in the form of Intel Optane enables programmers to write recoverable programs. However, the data on NVM is susceptible to a plethora of data remanence attacks, ... -
Homeostasis of cyclic-di-AMP in Mycobacterium smegmatis: Functional and structural contributions of c-di-AMP synthase (MsDisA) and hydrolase (MsPDE)
In bacteria, cyclic-di-nucleotide based second messengers regulate various physiological processes including the stress response. For the past decades, cyclic diadenosine monophosphate (c-di-AMP) has emerged as a crucial ... -
Transcription termination in Mycobacteria
Transcription termination is one of the key events of gene expression that decides the boundary of the gene. Termination either before the stop codon or transcriptional read-through into the downstream gene both have ... -
Opportunistic Beamforming and Asymptotic Throughput Analysis of Hybrid Analog-Digital mmWave Multi-User MIMO Systems
In this thesis, we address the problem of large training/feedback overhead and the requirement of computationally intensive algorithms to determine the phase angles of the analog precoder for downlink data transmission ... -
Extraction of Equivalent Uniaxial Plastic and Viscoplastic Behavior from Bending Using a Mechanistic Approach
The present work is aimed at the extraction of material’s yield and creep parameters using cantilevers by conducting constant deflection rate and constant load tests respectively. Under the assumption of Euler-Bernoulli’s ... -
Modelling spatial and non-spatial conflicts across multiple design domains
This thesis aims to detect spatial and non-spatial conflicts in product design arising out of requirements in different design domains. Handling such conflicts requires modelling the non-geometric knowledge outside the ... -
Efficient Resource Allocation for Underlay Device-to-device Communication Networks with Limited Channel State Information
Device-to-device (D2D) communication is finding applications in future wireless networks such as vehicular networks and internet-of-things. It offloads traffic from the base station (BS), improves energy efficiency, and ... -
An Evaluation of Basic Protection Mechanisms in Financial Apps on Mobile Devices
This thesis concerns the robustness of security checks in financial mobile applications (or simply financial apps). The best practices recommended by OWASP for developing such apps demand that developers include several ... -
Multi-linear Disassembly Path Determination: A Geometric Approach
This thesis presents a geometric approach for determining the orientation-preserving disassembly paths of polyhedral assembly components. Exact disassembly path determination of the components is essential because the ... -
