Noise generated due to flow over corrugated pipes has extensively been studied, because of its presence in various engineering applications. Flexible risers used in the oil and gas industry are one of these applications, where noise is produced due to corrugations present at the innermost layer of the riser. Dry-gas flow through a corrugated...

In recent years, personalized recommender systems have been facing criticism in research due to their ability to trap users in their circle of choices, called "filter-bubble", thereby limiting their exposure to novel content. In solving the issue of filter-bubble, past research has focused on providing explanations to users about how a...

A comprehensive understanding of the stability of shear flows is a fundamental problem in fluid mechanics and it has been a subject of both theoretical and practical interest in engineering research. A key aspect of these dynamic flows is the behaviour exhibited by the instabilities as it evolves from initial small perturbations of an...

The emergence of the Data Marketplaces is the latest iteration in the phenomenon of data-driven transformation of the world. Data marketplaces have emerged as a new form of data-driven business models which enable trading of data between the data owners/providers and data consumers by providing the necessary technological and non-technological...

This thesis details the design of a self-oscillating MEMS resonator as a pressure sensor. A bi-layer circular diaphragm with a single center perforation is used as a pressure sensitive membrane which measures the absolute pressure of the surrounding medium. A novel aspect of the proposed sensor is that the resonator is made to oscillate by an...

A large part of the global population is still living without the access to electricity. The interconnected solar home system (SHS) has been purposed as a solution to meet the local demand in the remote areas. In this thesis, a decentralized architecture of SHS is considered which consists of four converters. This work proposed the design of one...

Weak capture in the restricted problem of three bodies refers to transitory motion between the primaries. Such behavior has interesting applications in space mission design, notably, in finding optimal transfer trajectories that surpass the performance of traditional Hohmann transfers. The Weak Stability Boundary (WSB) is a mathematical set that...

With the performance of single-core processors approaching its limits, an increased amount of research effort is focused on chip multiprocessors (CMP). However, existing lock-based synchronization methods that are critical to performing parallel computation possess limited scalability and are inherently complex to use while programming. This...

IN-FLOW deals with a context driven research into the unique ephemeral nature of a temporary pop up city in India. The site is situated in the northern city of Allahabad[now Prayagraj] at the confluence of two river, Ganga and Yamuna respectively. The site facilitates the gathering for religious festival called “The Kumbh Mela”. It is the...

The demand for electric vehicles (EVs) and wind turbines have been rising significantly in the EU as the EU wants to become carbon neutral by 2050 and generate 40% of its energy through renewable sources in order to avoid climate change and its consequences. However, both these technologies use several critical raw materials essential for their...

The interest in high performance three-dimensional (3D) imaging has grown in recent years due to immense demand in engineering, science, medicine and entertainment domains. The driving goals of state-of-the-art 3D imagers are high sensitivity to light and fine depth resolution at long range. Furthermore, high level of integration is desirable to...

Detailed imaging of blood flow may improve the understanding of brain functions. The state-of-the-art non-invasive flow imaging of the brain is limited to a one-dimensional Doppler setting. We propose a method to estimate the two-dimensional flow vector in the fine vascular network of the brain by using a speckle tracking technique. The...

The environment in which microscopic organisms live in is dominated by viscous forces because of their small length scales. Inertial forces are of little use to them in their propulsion mechanisms. As a consequence of this, an organism such as the scallop which moves through time-reversible deformations of its body would not propel itself in a...

The goal of this graduation project was to investigate if 3D printing could serve as a promising alternative for manufacturing spare parts needed for the re-manufacturing of diesel injection pumps. This project was conducted under the EU ReCiPSS project, along with the support of Robert Bosch GmbH. The proposition was investigated on three...

The coalescence of two droplets suspended in a viscous fluid is the focus of this study. When two droplets that are suspended in a shearing flow come in contact with each other, it is currently uncertain if the contact would result in coalescence. To be able to make such predictions, it is necessary to study the effects of the system parameters,...
