Studies On The Viability Of The Boundary Element Method For The Real-Time Simulation Of Biological Organs
(2016-09-02)Realistic and real-time computational simulation of biological organs (e.g., human kidneys, human liver) is a necessity when one tries to build a quality surgical simulator that can simulate surgical procedures involving ... -
Evolution Of Texture And Its Correlation With Microstructure And Mechanical Property Anisotropy In AA7010 Aluminum Alloy
(2016-07-12)Al-Zn-Mg-Cu-Zr based AA7010 aluminum alloy belongs to the class of heat treatable alloys and the semi-finished products are generally produced by hot rolling, forging or extrusion processes. It is well known that the ... -
Optimal Guidance Of Aerospace Vehicles Using Generalized MPSP With Advanced Control Of Supersonic Air-Breathing Engines
(2016-07-11)A new suboptimal guidance law design approach for aerospace vehicles is proposed in this thesis, followed by an advanced control design for supersonic air-breathing engines. The guidance law is designed using the newly ... -
Seismotectonics Of The Andaman-Nicobar Plate Boundary And Evaluation Of 2004 Deformational And Depositional Features Towards Assessing Past Tsunamigenic Earthquakes
(2016-07-11)Tsunami hazards were greatly underestimated along the coasts of countries bordering the northeastern Indian Ocean until the occurrence of the 26 December 2004, Mw 9.2 earthquake and its ensuing tsunami. Sourced off the ... -
Regional Hydrologic Impacts Of Climate Change
(2016-06-27)Climate change could aggravate periodic and chronic shortfalls of water, particularly in arid and semi-arid areas of the world (IPCC, 2001). Climate change is likely to accelerate the global hydrological cycle, with increase ... -
High Reynolds Number Flow Over A Backward-Facing Step
(2016-06-21)Flow separation and reattachment happens in many fluid mechanical situations occurring in engineering applications as well as in nature. The flow over a backward-facing step represents a geometrically simple flow situation ... -
Study Of Multiple Asperity Sliding Contacts
(2016-06-18)Surfaces are rough, unless special care is taken to make them atomically smooth. Roughness exists at all scales, and any surface-producing operation affects the roughness in certain degrees, specific to the production ... -
Prediction Of The Mechanical Behaviour Of A Closed Cell Aluminium Foam Using Advanced Nonlinear Finite Element Modelling
(2016-05-06)Cellular materials like aluminum foam which is the subject of interest here are generally characterized by high energy absorption capacity per unit weight. Materials of this category can be ideal for applications such as ... -
Study Of Solidification And Microstructure Produced By Cooling Slope Method
(2016-05-05)In most casting applications, dendritic microstructure morphology is not desired because it leads to poor mechanical properties. Forced convection causing sufficient shearing in the mushy zone of the partially solidified ... -
Variation Of Marine Boundary Layer Characteristic Over Bay Of Bengal And Arabian Sea
(2016-05-04)The atmospheric boundary layer (ABL) is the lowest layer of the atmosphere where surface effects are felt on time scales of about an hour. While its properties are determined by the surface characteristics, season and ... -
Tensile Behavior Of Free-Standing Pt-Aluminide (PtAl) Bond Coats
(2016-05-03)Pt-aluminide (PtAl) coatings form an integral part of thermal barrier coating (TBC) systems that are applied on Ni-based superalloy components operating in the hot sections of gas turbine engines. These coatings serve as ... -
Modeling The Population Dynamics Of Erythrocytes To Identify Optimal Drug Dosages For The Treatment Of Hepatitis C Virus Infection
(2016-04-28)The current treatment for hepatitis C virus (HCV) infection – combination therapy with pegylated interferon and ribavirin – elicits sustained responses in only ~50% of the patients treated. Greater cumulative exposure ... -
Determination Of Isopectral Rotating And Non-Rotating Beams
(2016-04-27)In this work, rotating beams which are isospectral to non-rotating beams are studied. A rotating beam is isospectral to a non-rotating beam if both the beams have the same spectral properties i.e; both the beams have the ... -
Behaviour Of Geosynthetic Reinforced Soil–Aggregate Systems Under Static, Repeated And Cyclic Loads
(2016-04-26)Efficient road network and connectivity play vital role in the development of any country. Majority of the rural roads are unpaved and connectivity of rural roads is always a major challenge. Unpaved roads are also used ... -
