Understanding And Supporting Conceptual Design Synthesis Of Multiple State Mechanical Devices
(2015-08-07)Conceptual design synthesis is part of the conceptual phase of the design process, which focuses on creating alternative, candidate solutions. Conceptual design phase has the greatest influence on the cost and characteristics ... -
Understanding Catchment Scale Processes: Hydrological Modelling and Information-Theoretic Approaches
Catchments are complex environmental systems, and they serve as the fundamental units for hydrological classification. They are self-organizing systems whose form, drainage network, ground and channel slopes, channel ... -
Understanding Context In Designing
(2009-05-25)Everything around us that is not a simple untouched piece of nature has been designed by someone. Human society has found a great refuge in these designed objects or the artefacts, and thus has adapted vociferously to their ... -
Understanding deformation mechanisms in the Hall-Petch breakdown regime of Ni-W alloys
The substantially higher strengths of nanocrystalline metals has been to attributed to the well-known Hall-Petch relationship σ= σ_o+k_HP d^(-1/2) where 𝜎 is the yield stress, 𝜎𝑜 is the lattice friction stress, 𝑑 is ... -
Understanding High Speed Mixing Layers with LES and Evolution of Urans Modeling
(2017-11-15)This thesis is concerned with studies on spatially developing high speed mixing layers with twin objectives: (a) to provide enhanced and detailed understanding of spatial development of two-dimensional mixing layer emanating ... -
Understanding Knowledge Needs And Processes In Design
(2011-01-31)In this knowledge economy, organizations are leveraging their competence through the knowledge they possess. Managing knowledge will potentially retain the competence held by the organization if knowledge generated across ... -
Understanding Structure And Growth Of Physisorbed Films : A Combined Atomic Force Microscopy And Modeling Study
(2014-10-16)Surface modification has wide ranging implications in lubrication, microelectromechanical systems (MEMS), colloidal systems and biological membranes. Surface modification plays an important role in stabilizing gold ... -
Understanding the demixing behavior and structure-property correlation in graphene oxide containing LCST blends
A number of researchers have studied about the effects of different nanoparticles on the phase separation of LCST polymer blend systems. Many nanoparticles such as carbon nanotubes and silica have been incorporated in ... -
Understanding the dynamics and evolution of cratons
The earth is the only rocky planet in the solar system that exhibits plate tectonics. One of the basic tenets of plate-tectonics is that it recycles the lithosphere within a few hundred million years. No oceanic lithosphere, ... -
Understanding the interplay between immune response and virus evolution
RNA viruses are the underlying cause of many human diseases, including the common cold, influenza, dengue fever, and COVID-19. Their ability to evolve rapidly makes them challenging to tackle, resulting in public health ... -
Uniaxial Fatigue Behavior of Freestanding Platinum-Aluminide (PtAl) Bond Coat
Pt-aluminide (PtAl) bond coat is used as a part of Thermal Barrier Coating (TBC) system on Ni-base superalloy components in advanced gas turbine aeroengines. The thickness of B2-NiAl intermetallic based diffused coating ... -
A Unified Constitutive Model For Large Elasto-plastic Deformation
(2009-07-23)Rapid development and stiff competition in material related industries such as the automotive, demand very high precision in end products in very quick time. The transformation of raw material into an intricate-shaped final ... -
A Unified Framework For Micromechanical Damage Modeling In Laminated Polymer Matrix Composites
A unified numerical framework for progressive damage analysis in polymer matrix composite (PMC) laminates has been developed by explicitly accounting for damage progression at the micro-level. A three-dimensional repeating ... -
A Unified, Configurable, Non-Iterative Guidance System For Launch Vehicles
(2011-02-10)A satellite launch vehicle not subjected to any perturbations, external or internal, could be guided along a trajectory by following a stored, pre-computed steering program. In practice, perturbations do occur, and in order ... -
Unraveling the Evolutionary Advantages of Crosstalk Between Two-Component Signalling Systems of M tuberculosis
(2018-05-29)M. tuberculosis (Mtb) senses and responds to changes in its environment primar-ily through two-component signalling systems (TCSs). Each TCS contains a trans-membrane histidine kinase (HK ) protein and a cytoplasmic response ... -
Unsteady Flow Field Downstream Of A Sudden Expansion
(2009-04-02)Separating and reattaching flows are important in a large number of engineering configurations. The flow through a sudden expansion (backward-facing step) represents a conceptually simple case of this class of flows and hence ... -
Unsteady Two Dimensional Jet with Flexible Flaps at the Exit
(2017-11-13)The present thesis involves the study of introducing passive exit flexibility in a two dimensional starting jet. This is relevant to various biological flows like propulsion of aquatic creatures (jellyfish, squid etc.) and ... -
Upper Bound Finite Element Limit Analysis for Problems of Reinforced Earth, Unsupported Tunnels and a Group of Anchors
(2017-11-27)This thesis presents the implementation of the upper bound limit analysis in combination with finite elements and linear optimization for solving different stability problems in geomechanics under plane strain conditions. ...
