Flow Over A Circular Cylinder With A Flexible Splitter Plate
(2010-07-08)Previous work on rigid splitter plates in the wake of a bluff body has shown that the primary vortex shedding can be suppressed for sufficiently long splitter plates. In the present work, we study the problem of a flexible ... -
Fluid-Elastic Interactions in Flutter And Flapping Wing Propulsion
(2017-10-06)This study seeks to understand the interplay of vorticity and elasto-dynamics that forms the basis for a fluttering flag and flapping wing propulsion, and factors that distinguish one from the other. The fluid dynamics is ... -
Flutter Identification and Aeroelastic Stability during Wake Penetration
Demonstration of utter stability over the design envelope and identi fication of safe ight envelope is a prerequisite for operational clearance of any new aircraft design. An important step involved in flight flutter ... -
Flutter Susceptibility Assessment of Airplanes in Sub-critical Regime using Ameliorated Flutter Margin and Neural Network Based Methods
(2018-02-17)As flight flutter testing on an airplane progresses to high dynamic pressures and high Mach number region, it becomes very difficult for engineers to predict the level of the remaining stability in a flutter-prone mode and ... -
Force Measurements On Rigid And Flexible Oscillating Foils
(2013-10-04)In the present work, we experimentally study thrust generation from sinusoidally pitched rigid and flexible foils immersed in a uniform flow. The flexible foils are made by attaching a flexible flap of known flexural ... -
Force-Amplifying Compliant Mechanisms For Micromachined Resonant Accelerometers
(2013-04-04)This thesis work provides an insight into the design of Force-amplifying Compliant Mechanisms (FaCMs) that are integrated with micromachined resonant accelerometers to increase their sensitivity. An FaCM, by mechanically ... -
Formation and Maintenance of the Southern Bay of Bengal Cold Pool
(2018-06-11)Around Sri Lanka and to the south of India sea surface temperatures (SST) are cooler compared to the surrounding region during summer monsoon. This region where SSTs are relatively cooler is known as the cold pool. Owing ... -

Formation of Porous Metallic Nanostructures Electrocatalytic Studies on Self-Assembled Au@Pt Nanoparticulate Films, and SERS Activity of Inkjet Printed Silver Substrates
(2018-04-24)Porous, conductive metallic nanostructures are required in several fields, such as energy conversion, low-cost sensors etc. This thesis reports on the development of an electrocatalytically active and conductive membrane ... -
Formulation of A Framework for Needs Analysis and Stakeholders' Behavioral Simulation for Design for the BOP
Poverty, and associated undesirability, distinguishes a population as Base of the (economic) Pyramid (BoP). Lack of necessities and vulnerability negatively affect the well-being of BoP populations. Literature reveals ... -
Formulations for solving geomechanics stability problems using stress characteristics and finite element limit analysis with power type and Mohr-Coulomb yield criteria
In geotechnical engineering, the stability analysis is often carried out to determine the ultimate collapse load that a geo-structure can possibly withstand. The accurate prediction of the exact collapse load is often very ... -
Fracture and Deformation in Bulk Metallic Glasses and Composites
(2018-01-11)Plastic flow in bulk metallic glasses (BMGs) localizes into narrow bands, which, in the absence of a microstructure that could obstruct them, propagate unhindered under tensile loading. In constrained deformation conditions ... -
Fracture And Fatigue Behavior Of Concrete-Concrete Interfaces Using Acoustic Emission, Digital Image Correlation And Micro-Indentation Techniques
(2011-04-05)Currently, the maintenance and repair of civil engineering infrastructures (especially bridges and highways) have become increasingly important, as these structures age and deteriorate. Interface between two different mixes ... -
Fracture and Fatigue Behaviour of Notched Plain Concrete Beams: The Role of Theory of Critical Distances and Acoustic Emission
Concrete structures, including buildings, bridges, pavements, and offshore structures, face a wide range of loading conditions, both static and cyclic. When subjected to fatigue loading, the response of concrete elements ... -
Fracture Behaviour including Size Effect of Cement Stabilised Rammed Earth
(2018-01-30)Rammed earth is a monolithic construction formed by compacting processed soil in progressive layers. Rammed earth is used for the construction of load bearing walls, floors, sub base material in roadways, airport runways, ... -
Fracture Characteristics Of Self Consolidating Concrete
(2010-07-16)Self-consolidating concrete (SCC) has wide use for placement in congested reinforced concrete structures in recent years. SCC represents one of the most outstanding advances in concrete technology during the last two ... -
Fracture Energy And Process Zone In Plain Concrete Beams (An Experimental Study Including Acoustic Emission Technique)
(2013-05-20)Concrete, which was hitherto considered as a brittle material, has shown much better softening behavior after the post peak load than anticipated. This behavior of concrete did put the researchers in a quandary, whether ... -
Fracture Of Plain Concrete Beams Via Fractals
(2009-09-02)The quantitative description of rough fracture surfaces of concrete has been an important challenge for many years. Looking at the fracture surface of a concrete specimen, one realizes that the self-affine geometry of crack ... -
A Framework for Effectiveness-based Sustainability Assessment in Manufacturing – A Product Life Cycle Approach
In recent decades, various human health impacts and environmental concerns (e.g., microplastic pollution, chemical exposure, biodiversity loss) associated with manufacturing/product life cycles have surfaced, threatening ... -
A framework for optimizing immunotherapy for long-term control of HIV
HIV infects around 1 million people every year. Antiretroviral therapy (ART) is used to suppress viral replication and control disease progression but it cannot eradicate the virus. ART is therefore lifelong. Today, e ...
