In this report, the analysis and design of a system that extracts keyframes from videos is detailed. The need for such a sub-module stems from the similarity of frames in a video. To aid in reducing the computation time of the content based video search engine, the Keyframe Extraction Module reduces the amount of frames by discarding frames that...

Image reconstruction from neural activation data is a field that has been growing in popularity with developments such as neuralink in the brain-machine interface space. To make better decisions when collecting data for this purpose, it is important to know what qualities to optimize for. The present paper investigates the relation between...

Artificial Intelligence has become a dominant part of our lives, however, complex artificial intelligence models tend to use a lot of energy, computationally complex operations, and a lot of memory resources. Therefore, it excluded a whole class of hardware in its applicability. Namely, relatively resource-constrained low-cost hardware. This...

Static Timing Analysis (STA) is one approach to verify the timing of a digital circuit. The currently used Gate Level Model (GLM) has limitations on performing STA for circuits when taking process variations into consideration. The transistor level model is developed taking the statistical factors into account. This thesis presents an...

Machine learning models are so-called a "black box," which means people can not easily observe the relationship between the output and input or explain the reason for such results. In recent years, much work has been done on interpretable machine-learning, such as Shapley values, counterfactual explanations, partial dependence plots, or saliency...

THE BRIEF &amp; HET TUSSENLAND<br/>The moment a patient receives the diagnosis of an incurable disease, it often feels like their whole world collapses. One patient explained this feeling as entering the in-between-land, the transition period from ending curative care and entering the end-of-life care. This in-between-land feels like entering an...

Natural ventilation is a traditional but effective way in buildings to adjust the indoor environment. It has also been proved to be effective in today’s design, if applied appropriately. At the same time, there is a growing trend that higher and higher buildings are constructed in the crowded city area. Air velocity, temperature and other...

In the electricity system, one barrier to the energy transition is the degradation of frequency stability due to the decrease of system inertia and frequency control ancillary services (FCAS), which is caused by the replacement of inertia-abundant and governor-based conventional power plants with zero-inertia and inverter-based renewable energy...

Guangzhou is one of the biggest cities in China, and it is located in Pearl River Delta, which has a vulnerable natural environment. In history, the development of Guangzhou city was inseparable from its canal system, which was developed from the natural dense river network. On the one hand, this system had played its role in water management...

Loss of lateral stability is still a major cause of road accidents in recent years. Nonlinear<br/>model predictive control (NMPC) is regarded as a powerful tool to improve vehicle safety by<br/>fully utilizing the tire-road friction. However, the computational load is excessive for on-board<br/>hardware, thus NMPC is yet distant from real-time...

Climate change is a global issue that influences worldwide. Its impacts are expected to be particularly severe in coastal cities, which are the center of discussion addressing this phenomenon. While it is impossible to ever fully eliminate risks from flooding, there are many measures available to manage and adapt to those risks. The Embarcadero,...

The graduation project reconsiders the role of municipal space in the public realm and the relationship between the municipality and citizens. It’s a reflection on the social phenomenon that people have insufficient opportunities to speak up for themselves and insufficient democratic engagement in the metropolis. Located in the center of this...

We focus on the problem of estimating human hand-tremor frequency from input RGB video data. Estimating tremors from video is important for non-invasive monitoring, analyzing and diagnosing patients suffering from motor-disorders such as Parkinson’s disease. We consider two approaches for hand-tremor frequency estimation: (a) a Lagrangian...

The inertial response plays a vital role in electrical networks to reduce the rate of change of frequency (RoCoF) following a contingency event. If the inertia has a low or zero value due to a lack of synchronous generators, then the electrical network might experience large undesirable frequency deviations. To overcome this problem, in previous...

Plasticity accompanied by dislocation motion is the essential property of metals. A large number of crystal plasticity models have been developed to predict the mechanical response in the work hardening regime while little attention is paid to pre-yield behavior. In this work, we propose a novel model both pre-yield and post-yield from a...

In this thesis, we will analyze swaptions whose short term interest rates are assumed to follow some affine models with dimension of factors more than two, so called multiple-factor interest rate models. Considering there is generally no analytical swaption price, we attempt to approximate it, and our discussion will focus on one of these...
