Demonstration Of Supersonic Combustion In A Combustion Driven Shock-Tunnel
(2011-01-17)For flights beyond Mach 6 ramjets are inefficient engines due to huge total pressure loss in the normal shock systems, combustion conditions that lose a large fraction of the available chemical energy due to dissociation ... -
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, ... -
Denoising And Inpainting Of Images : A Transform Domain Based Approach
(2009-05-25)Many scientific data sets are contaminated by noise, either because of data acquisition process, or because of naturally occurring phenomena. A first step in analyzing such data sets is denoising, i.e., removing additive ... -
Denoising and Refinement Methods for 3D Reconstruction
Capturing raw 3D data from the real world is the initial step for many 3D reconstruction pipelines in different computer vision applications. However, due to inaccuracies in measurement and oversimplification in mathematical ... -
DeNOx Studies In Diesel Exhaust Under AC/Pulse Energizations
(2015-11-16)It is the need of the hour to reduce the pollutants which poison our atmosphere and harm our health. The diesel engines are the most efficient IC engines in the world today, but paradoxically, they are also the engines ... -
Densification Mechanisms for Spark Plasma Sintering in Alumina and Alumina Based Systems
(2018-03-19)The densification mechanisms of polycrystalline α-alumina by spark plasma sintering are highly contradictory, with different research groups suggesting diffusion to dislocation controlled mechanisms to be rate controlling. ... -
Densification, Oxidation, Mechanical And Thermal Behaviour Of Zirconium Diboride (ZrB2) And Zirconium Diboride - Silicon Carbide (ZrB2-Sic) Composites
(2016-11-23)Sharp leading edges and nose caps on hypersonic vehicles, re-entry vehicles and reusable launch vehicles are items of current research interest for enhanced aerodynamic performance and maneuverability. The unique combination ... -
Density functional and computer simulation studies of colloidal suspensions
Colloidal suspensions of polyballs (polystyrene spheres) are good model systems for the study of both structural and dynamical properties of solids and liquids because the pair-wise interaction between the colloidal particles ... -
Density matrix renormalization group studies of low-dimensional magnetic systems and conjugated polymers
To conclude, we have performed symmetrized DMRG calculations on the extended Hubbard–Peierls model. We have presented the dependences of exciton binding energy both on alternation ? and nearest-neighbor interaction parameter ... -
Density Stratified Thermal Energy Storage System and Associated Fluid Dynamic Perturbations
The hunger of humankind for energy has reached unprecedented levels with the ever-rising industrialization and global population surge. We are witnessing a global economic evolution towards a clean, affordable, sustainable ... -
Dependency-lattices, acyclic hypergraphs and relational database scheme design
Compared to other models of data, the relational model offers several advantages: Clear separation between logical organization and physical storage of data Ease of understanding the logical structure Use of high-level ... -
Deploying an Orthogonal Turn for Isolation of Rare Cell Populations from Vascular Environments
Cancer cells are shed from metastatic primary tumors, bearing the potential for blood-borne metastasis to distant vital organs. Metastasis is predominantly responsible for cancer-related deaths. These circulating tumor ... -
Dereverberation of Speech Using Autoregressive Models of Sub-band Envelopes
Automatic speech recognition (ASR) based technologies are radically changing the way we interact with digital services and information. Most of these application leverage on hands-free speech, where talkers are able to ... -
A Descriptive Hierarchical Approach to Analyse Activities Through Causal Mechanistic View
Activities of Daily Living (ADLs) are essential routines that support individuals’ independence and well-being. For people with upper limb impairments, limitations in hand and arm function can make performing ADLs ... -
