Silicon photonics is a promising platform for photonic devices and circuits, largely driven by advanced complementary metal-oxide-semiconductor (CMOS) processing technology. An extremely crucial component for a photonic ...

Earthquakes are among the deadliest in all the natural disasters and have affected many people in the last few decades. The efforts to reduce or mitigate the impact of earthquakes have become increasingly focused upon ...

Wave propagation in elastic continuum is a subject of interest in many fields of engineering and has been explored for several decades from theoretical, computational and experimental perspective. In this context, a ...

Sink flow turbulent boundary layers (TBLs) develop in the incompressible flow be- tween two convergent, plane smooth walls and represent a family of favorable pres- sure gradient TBLs. These are the only smooth wall TBLs ...

During lift-off of launch vehicles jets from nozzles impinge on a wedge deflector which directs the jet away from the rocket along passages. As a high Reynolds number turbulent flow the whole region has a broad spectrum ...

Granular flows have always fascinated researchers through its complex and mysterious behavior. Although a collection of solids, they exhibit properties like that of fluids. Flows over an inclined plane, known as chute flow, ...

The interpretation of proxies of paleo monsoons has been based primarily on changes in incident solar radiation. The role of feedbacks has not been examined in depth. In this thesis, we have used a diagnostic model of ...

Magnetic nano-particles dispersed in a non-magnetic matrix is promising for storage technology. Additionally, such magnetic nano composite (MNC) materials have potential applications in the field of telecommunication, ...

Rise in autonomy has led to increase in usage of Unmanned Aerial Vehicles (UAVs) for various applications and has allowed the UAVs to perform complex and hazardous missions with ease. Formation of multiple UAVs finds ...

This thesis deals with ultrasonic guided wave based non-destructive inspection and health monitoring of aircraft structural components using a non-contact sensing scheme based on laser Doppler scanning imaging technique. ...
