Indoor climate installations are widely used in modern office buildings. Statistical data show that the energy consumption in buildings has grown quickly in the past decades. A considerable part is due to inefficient and improper operations of installations. Therefore, Fault Detection and Diagnosis (FDD) for indoor climate installations has...

This thesis describes the design of a front-end application-specific integrated circuit (ASIC), which will be put into the tip of a miniature ultrasound probe for 3D Trans-Esophageal Echocardiography (TEE). To enable 3D TEE, a matrix piezoelectric ultrasound transducer with more than 2000 elements will be used. Since a gastroscopic tube cannot...

During the past three decades, China has achieved impressive economic development. However, the pollution and resource depletion that accompanied China's rapid industrialization have led to severe environmental issues, such as ecosystem degradation, groundwater contamination and smog, which have turned into visible crises. In China, industrial...

Fly ash is a by-product of burning coal in electric power generating plants. It is commonly known that owing to its pozzolanic properties fly ash is widely used as a partial replacement for Portland cement in concrete. The use of fly ash in concrete not only reduces the landfill costs of fly ash, but also reduces the use of Portland cement in...

Public infrastructure is often mentioned as a key to promoting economic growth and development. This belief has been supported by the observation of rich countries, such as the U.S., Japan and those in Western Europe, where plenty of infrastructures developed during times of rapid economic growth. China has been one of the world’s fastest...

The presented thesis aims at understanding the relationship between the synthesis procedure of argyrodite Li6PS5X (X=Br, Cl) solid electrolytes and the resulting structure, morphology, and solid-state battery performance. Specifically, argyrodite solid electrolytes in combination with Li2S positive electrodes were investigated using X-ray and...

Blade Element Momentum (BEM) is the most important aerodynamic analysis method for wind turbines. BEM is derived assuming stationary conditions, which limits its ability to model the unsteady aerodynamic effects. This becomes increasingly relevant for the flexible blades of current large-scale turbines, and the employment of passive and active...

It is difficult to accurately predict the strength of masonry and concrete structures. The most widely used method for simulating their behaviour is finite element analysis with the Newton-Raphson method and arch length control. However, the Newton-Raphson method can diverge and not produce a result, for example in bifurcations or during snap...

During the past few decades, numerous protein-based pharmaceuticals to treat chronic and life-threatening diseases have emerged. The short plasma half-life of therapeutic proteins requests frequent administration, usually via parenteral routes. This short-coming is proposed to be solved by the development of an injectable microparticulate drug...

The development in computational simulation techniques has brought significant progress in the realization of computational alloy design. The advantages are most significant when developing novel materials of which the research & development cycles are particularly time and energy (and hence cost) consuming, such as high-temperature alloys....

Memristive devices are promising candidates as a complement to CMOS devices. These devices come with several advantages such as non-volatility, high density, good scalability, and CMOS compatibility. They enable in-memory computing paradigms since they can be used for both storing and computing. However, building in-memory computing systems...

Catastrophic breakage of a material might bring severe accidents in aerospace engineering, construction, and transportation field. Therefore, engineering material with high toughness values is very important for these special applications. Many biological materials in nature, such as nacre, silk, and wood, possess high toughness values because...

Creating a gas-liquid foam means dispersing gas as individual bubbles in an aqueous solution, in which each gas bubble is separated by liquid films or lamella. The most common form of liquid foam (as opposed to solid foams, like polymer sponges) seen in day-to-day life is bulk foam. This refers to a foam that rests in a large container (or flows...

The study of the light field has become a valuable framework for capturing and analysing the complex distribution of light in natural environments. The directional, spatial, temporal and spectral structure of light, collectively influence the optical information available to an observer and thus impact our perception of the surrounding world....
