Computing Contour Tress for 2D Piecewise Polynomial Functions
Contour trees are extensively used in scalar field analysis. The contour tree is a data structure that tracks the evolution of level set topology in a scalar field. Scalar fields are typically available as samples at ... -
Molecular Genetic Analysis of Trichome Development in Arabidopsis thaliana
Several mutants with aberrant trichome patterning and differentiation are known in Arabidopsis. The genes involved in these processes code for proteins with diverse functions such as transcription, protein degradation, ... -
New Models and Methods for Formation and Analysis of Social Networks
Social networks are an inseparable part of human lives, and play a major role in a wide range of activities in our day-to-day as well as long-term lives. The rapid growth of online social networks has enabled people to ... -
Microstructural Evolution of Directionally Solidified Ni-Al-Re/Ru Alloys
Nickel based superalloys are high temperature materials which find application as blade and disc components of jet engines due to their ability to retain their mechanical properties at temperatures close to 0.8 of their ... -
Studies of X-Ray Transients and a Future X-Ray Sky Monitor
For this thesis we studied X-ray transients. In addition we also studied some methods to study these transients, both observationally and in terms of the instrument used. The first transient studied is a black hole binary ... -
Experimental Studies on Gaseous Mixing in a Low Area Ratio Rectangular Supersonic Confined Jet
When a supersonic jet passes through a confined passage, it is called as supersonic confined jet. They are encountered in many aerospace applications such as supersonic ejectors, supersonic mixers/purgers, and thrust ... -
Salmonella Pathogenesis in Dendritic Cells : Stealthy Approach Against Adaptive Immune Response
Synopsis of work done by Mayuri Gogoi (SR No. 10-09-00-10-31-11-1-08534) for the award of Ph.D. degree in the Faculty of Science, Indian Institute of Science, Bangalore, India. Thesis title: Salmonella pathogenesis in ... -
Host Location in Non-pollinating Fig Wasps of Ficus Racemosa : Age, Oviposition History and the Ovipositor
The fig–fig wasp system is a brood site pollination system where pollinators breed inside an enclosed globular inflorescence (syconium) that they pollinate. This pollination mutualism is subjected to exploitation by the ... -
Notch3 Receptor : Activation Mechanism and Association with Ovarian Cancer
The Notch signaling influences a wide spectrum of cell fate decisions, both during development and in the adult organisms. This pleiotropic role of Notch signaling in humans is attributed partially to the presence of four ... -
Numerical Modelling of Reinforced Concrete Structural Elements and Assemblages Exposed to Thermo-mechanical Loading
Fire represents one of the extreme loads that a structure may experience during its design life. In reinforced concrete (RC) structures, the mechanical properties of both concrete and steel deteriorates with rise in ... -
Effect of Surface Texture on Friction under Dry Reciprocating Contacts
Surface texture has been successfully used in many fields to improve the performance of surfaces, in applications like drag reduction, control of wettability, and enhancement of heat transfer. In tribology, surface texture ... -
New Techniques for Automatic Short Answer Grading
Assessing acquired knowledge by students is one of the key aspects of the pedagogical ecosystem. A significant part of a teacher’s time is spent towards grading responses of students to questions given in assignments and ... -
Program Repair by Automated Generation of Hints
Programming has become an important skill in today's technology-driven world. It is a complex activity because of which programmers make mistakes in their software. Student programmers make mistakes in their programs due ... -
Characterization of Thymocyte Subpopulations and Mechanistic Insights during Various Modes of Thymic Atrophy
T lymphocytes along with B lymphocytes constitute the adaptive immune system, which is critical for host defence. The progenitors of T cells arise in the bone marrow and the sequential development of T cells occurs in the ... -
Electron Microscopy Investigation of Formation Mechanism, Structure and Stability of Functional Nanostructures & Hybrids
Micro/nano-structural characteristics of functional materials play a crucial role in their properties. In that spirit, it is of utmost importance to explore the ‘room at the bottom’, to characterize the functional nanomaterials ... -
Crystallization and Preliminary Structural Studies on Mycobacterium tuberculosis RuvX
The deadly pathogen Mycobacterium tuberculosis has been characterized for its virulence in immense detail. Regardless of this, the capability of M. tuberculosis to combat extreme stress conditions inside the host cell for ... -
Synergistic Influence of Gene Architecture and Promoter Structure on Transcription in Plants : An in silico Analysis
Understanding the structural organisation of genome and insightful information of gene has helped in exploring the regulation and expression of the gene at a molecular and cellular level. In eukaryotes, the gene regulation ... -
Nano Surface Modifications for Anti-Corrosive and Anti-Biofouling Applications
Microbially Induced Corrosion (MIC) of materials is a major concern of marine industry. Various ferrous and non-ferrous materials used in industry are prone to MIC. Bio-fouling or formation of bio-film on material surface ... -
Design, Analysis, Simulation and Experimentation of a Flexible Spine Quadruped
Quadrupeds robots can move on uneven and rough terrain where mobile robots cannot venture. Al-though bipeds have more capabilities, they are inherently unstable and difficult to control. Most quadrupeds today are built ... -
Dendrimer Interactions with Cell Membrane and Pore Forming Toxins
Dendrimers are hyper-branched polymeric nanoparticles with a central core molecule connected by successive dendritic branching layers. The structure controlled parameters of den-drimers such as size, shape, surface chemistry, ...
