Normally off AlxGa(1-x)N/GaN devices: Materials, process and device architecture innovations
AlxGa(1-x)N/GaN HEMTs find applications in power electronics systems as high-frequency power switches. The formation of a highly mobile 2 dimensional electron gas (2DEG) at a heterointerface in an otherwise insulating wide ... -
ESD Reliability Physics and Reliability Aware Design of Advanced High Voltage CMOS & Beyond CMOS Devices
Electrostatic Discharge (ESD) reliability is one of the major reliability concerns in integrated circuits (IC), which if not addressed while designing devices and circuits, can lead to a permanent damage to the Integrated ... -
Cryomilled Group IV elements (Silicon & Germanium) for optoelectronic applications
Group IV elements such as silicon and germanium are elemental semiconductors and lead to the evolution of modern electronic applications. Synthesis of contamination-free nanoparticles of these materials in bulk quantity ... -
Biochemical and functional characterization of the enigmatic MPPED1/MPPED2 metallophosphodiesterases
Evolutionarily conserved genes in nature have been known to perform critical functions inside the cell. Earlier bioinformatic analysis performed in our laboratory identified mammalian orthologs of Rv0805, a novel class III ... -
Inverse problems solution using spectral finite element methods
Inverse problems are very challenging as these problems involve, finding the cause by analyzing the effects. In structural dynamics problems, the effects are normally measured in terms of dynamic responses in structures. ... -
Antibacterial Surfaces Mechanisms, Design and Development
The spread of disease-causing microorganisms through high-touch surfaces and their increased tolerance against antimicrobials and the host immune system is responsible for several fatal diseases. By the year 2050, Antimicrobial ... -
Sol-gel based organic-inorganic hybrid coatings for corrosion protection of aerospace aluminium alloy
Aluminium metal is known for its high electrical conductivity, thermal conductivity and high reflectivity. Aluminium alloys of 2XXX series, particularly the 2024 alloy with the quaternary Al–Cu–Mg–Mn composition are widely ... -
Biochemical and Functional Characterization of the Mycobacterial PdtaS-PdtaR Two Component System
Two-Component Systems (TCSs) are primarily prokaryotic modes of cell signaling involving a receptor sensor kinase (SK) that senses stimuli and a response regulator (RR) that effects a response, usually at the level of ... -
Local Interactions, Spatial Patterns and Ecosystem Stability
Many ecosystems exhibit striking patterns in the spatial distribution of organisms, for example, patterns of clumping and dispersion in semi-arid vegetation, mussel in intertidal beds and even sea-grass and macroalgae. ... -
Influence of the substrate specificity of Mycobacterium tuberculosis ClpX on the transcriptional profile
Cellular homeostasis in bacteria is maintained by diverse molecular machines. These include several one-component systems (OCS), two- component systems (TCS), chaperone proteins, proteases, proteolytic complexes and ... -
Financing of Technology Startups in Bangalore: An Empirical Study of Requirements, Sources and Performance
Tech startups are integral drivers of economic growth in any economy, given their potential role and significance in employment generation, wealth creation, and aggregate output of a nation. However, most startups are ... -
Investigations into Incineration of Sanitary Napkin Waste Using Single Chamber Incinerator
Commercially available disposable sanitary napkins are the most common method of menstrual hygiene management in most urban regions of India (van Eijk, 2016) (Mathiyalagen et al., 2017). It is estimated that in India a ... -
Stochastic approximation with set-valued maps and Markov noise: Theoretical foundations and applications
Stochastic approximation algorithms produce estimates of a desired solution using noisy real world data. Introduced by Robbins and Monro, in 1951, stochastic approximation techniques have been instrumental in the asymptotic ... -
Degradation Studies on Polymeric Insulators used for EHV and UHV Transmission
High voltage insulators used in overhead power transmission systems are of key im- portance for safe, reliable, and effcient operation of transmission line in transferring huge amount of electrical power. Conventionally, ... -
Isogeometric based formulations for the bending analysis of laminated composite structural elements
Isogeometric analysis (IGA) is a family of numerical methods to solve boundary value problems. The founding principle of isogeometric methods is aimed at integrating computer aided design (CAD) with nite element method ... -
