Direct Estimation of Acoustic Source Characteristics of the Internal Combustion Engine Exhaust System and Analysis of Complex Muffler Configurations
Reduction in noise radiated from the IC engines is needed to meet the ever increasingly stringent noise regulations. The unmuffled exhaust noise of an IC engine is the biggest contributor to the overall engine noise. ... -
Direct Measurement of Itinerant Magnetism & Interface States in Semiconductors using Time-varying Magnetic Fields
(2017-11-28)Magnetism in a solid | dia, para, ferro, or of other forms | originates majorly from its electrons; one could, infact, ignore the nuclear contribution. There are two types of electrons in a solid: bound, and free (also ... -
Direct Methods for Optimal Ascent Guidance
An ascent guidance algorithm determines the thrust vector that allows the spacecraft to reach the desired orbit. Generally, optimal ascent guidance algorithms try to reach the orbit while minimizing mission time or fuel. ... -
Direct Numerical Simulation of Square Vortex Flows
Atmospheric and oceanic flows are often modeled as two-dimensional due to their large planar extents (∼ 1000 km) and small vertical extent (∼ 10 km). Most phenomena in these systems are governed by the theory of two-dimensional ... -
Direct Numerical Simulations and Fluctuating Force Simulations of Turbulent Particle-gas Suspensions
(2018-05-18)Turbulent gas-particle suspensions are of great practical importance in many naturally phenomena, such as dust storms and snow avalanches, as well as in industrial applications such as fluidised, circulating bed reactors ... -
Direct Numerical Simulations of Fluid Turbulence : (A) Statistical Properties of Tracer And Inertial Particles (B) Cauchy-Lagrange Studies of The Three Dimensional Euler Equation
(2017-11-09)The studies of particles advected by tubulent flows is an active area of research across many streams of sciences and engineering, which include astrophysics, fluid mechanics, statistical physics, nonlinear dynamics, and ... -
Direct Time Domain Modelling Of First Return Stroke Of Lightning
(2009-05-21)Being one of the most spectacular events in nature, lightning is basically a transient high current electric discharge in the atmosphere, which extends up to kilometres. Cloud to ground discharge is the most hazardous one ... -
Directing cellular differentiation using biophysical cues on multifunctional biomaterial platforms for neural and osteochondral applications
World health organization (WHO) has recognized multiple degenerative diseases as the leading causes of mortality, globally. The drugs-based clinical treatment of chronic degenerative diseases such as multiple sclerosis, ... -
Discharge Plasma based NOx Abatement in Engine Exhaust Assisted by Industry Wastes : A Parametric Evaluation with Diesel Fuels and Corona Electrodes
Diesel engines contribute to a large percentage of oxides of nitrogen (NOx) emission in the atmosphere. The NOx primarily consists of nitric oxide (NO) and nitrogen dioxide (NO2). With depleting fossil fuel supplies ... -
Discharge Plasma Supported Mariculture and Lignite Waste for NOx Cleaning in Biodiesel Exhaust : Direct and Indirect Methods
(2018-06-18)One major aspect of environmental pollution affecting human life and climate is air pollution. The harmful pollutants in the air include mostly hydrocarbons, carbon monoxide, carbon dioxide, nitrogen oxides as well as soot ... -
Discovering Frequent Episodes : Fast Algorithms, Connections With HMMs And Generalizations
(2008-10-13)Temporal data mining is concerned with the exploration of large sequential (or temporally ordered) data sets to discover some nontrivial information that was previously unknown to the data owner. Sequential data sets come ... -
Discovering Frequent Episodes With General Partial Orders
(2013-06-04)Pattern Discovery, a popular paradigm in data mining refers to a class of techniques that try and extract some unknown or interesting patterns from data. The work carried out in this thesis concerns frequent episode mining, ... -
Discovering Roles In The Evolution Of Collaboration Networks
(2009-04-02)Searching the Web involves more than sifting through a huge graph of pages and hyperlinks. Specific collaboration networks have emerged that serve domain-specific queries better by exploiting the principles and patterns ... -
Discovery Of Application Workloads From Network File Traces
(2011-05-19)An understanding of Input/Output data access patterns of applications is useful in several situations. First, gaining an insight into what applications are doing with their data at a semantic level helps in designing ... -
Discrete particulate description of elastic structures undergoing geometrically nonlinear deformation and dynamic particle interaction
The mechanical behaviour of deformable bodies in a particulate environment has been an area of increasing interest across a wide spectrum of systems and scale. A composite ensemble of deformable structures and discrete ... -
Discrete Velocity Boltzmann Schemes for Inviscid Compressible Flows
It is known that high-speed flows are compressible. In large parts of the flow domains, the inviscid approximation is valid and this leads to Euler equations of gas dynamics. These inviscid compressible flows are modelled ... -
Discrete Velocity Boltzmann Schemes with Efficient Multidimensional Models
Traditional CFD algorithms have achieved a high degree of sophistication for modelling fluid flows in the past five decades. This sophistication can be seen clearly in one dimensional modelling, with a wide variety of ... -
