Current photovoltaic (PV) industrial chain mainly serves the conventional utility-scale PV power stations. Rigid and opaque silicon-based PV modules domain the market so far. As distributed PV capacities expand, PV modules tend to be integrated with existing infrastructures (mostly, buildings). To adapt with the building environment, innovative...

Kulkarni, A. (author)
The aim of this thesis is to study the nature of photoexcitations and carrier multiplication in low-dimensional semiconductors using ultrafast spectroscopy techniques. Ongoing from a macroscopic scale to a nanoscale, the electronic and
optical properties of a material become size dependent, and differ significantly from their bulk...

This thesis focuses on improving the phase noise and power efficiency
of millimeter-wave (mm-wave) frequency synthesizers in nanometer CMOS.
The mm-wave frequency spectrum is widely adopted in various upcoming
volume commercial wireless applications. These new applications provide
more interconnection between the physical and...

Shakerifard, B. (author)
Global warming, continuous demand on energy from fossil fuels as a limited natural resource, and costumers’ high expectations regarding product quality are three global challenges that the automotive industry is facing. Fuel consumption reduction has a significant impact on preserving fossil fuels, lowering fossil fuel dependency and the CO2...

Modern surveillance radars are designed to detect moving targets of interest in an adverse environment, which can encompass strong unwanted reflections from ground or sea surface, clouds, precipitation, etc. Detection of weak and small moving targets in environmental clutter remains, however, a challenging task for the existing radar systems....

At present, the rapid development of automation technologies allows robots remarkable precision and endurance, as well as the strength in accomplishing repetitive tasks. Despite this, manual control is still indispensable in many domains where robots and humans play complementary roles, as humans demonstrate superior competence in improvisation...

Programming languages are one of the key components of computer science,
allowing programmers to control, define, and change the behaviour of computer
systems. However, programming languages require considerable effort to design, implement, and maintain. Fortunately, declarative approaches can be used to define programming languages...

Koeman, V.J. (author)
Agent-oriented programming (AOP) is a programming paradigm introduced roughly thirty years ago as an approach to problems in Artificial Intelligence (AI). An agent is a piece of software that can perceive its environment (e.g., through sensors) and act upon that environment (e.g., through actuators). A cognitive agent is a specific type of agent...

Environmental flows (e-flows) science has significantly advanced in the last decades. In Mexico, a standard for e-flow assessments was recently published as a regulatory instrument to support water planning and management. However, the appropriateness of the technical procedure in a climate change context has not been investigated. Do the e...

Over the past few decades, there has been an increasing trend in the development of wearable robotics for rehabilitation and human augmentation. Although most such devices have been envisioned and realized to extend human capabilities, they do not primarily target balance control. For a wide range of physiotherapy recipients, impaired balance,...

Hermidas, N. (author)
Submarine gravity flows constitute the last link in the source-to-sink sediment transport chain. They are the main mechanism for the transportation of sediment from the shallower to the deeper parts of the ocean. Due to their great volume, mobility, and power, they pose a formidable threat to the offshore infrastructures, and can generate...

Tang, J. (author)
Foam has unique microstructure in pore networks and reduces gas mobility significantly, which improves considerably the sweep efficiency of gas injection. Foam injection is thus regarded as a promising enhanced oil recovery (EOR) technology. One key to success of foam EOR is foam stability in presence of oil. This thesis seeks to understand...

This paper examines a problem related to dispatching materials to spreaders in coal (lignite) mines operated under the paradigm of continuously excavated material flow. In the considered particular case, complexity arises from different material types of overburden to be placed on the dump site in pre-defined patterns that guarantee...

A multiscale fracture model is developed to study the influence of defects appearing at a microscale in a fiber-reinforced composite laminate. The model establishes a link between the geometrical characteristics of sub-ply imperfections that may be created during manufacturing and the overall fracture strength and fracture energy of the...

Marinkovic, I. (author)
This thesis explores the possibility of controlling the quantum states of high frequency mechanical resonators using infra-red laser pulses. Chapter 1 gives an overview of quantum technologies based on mechanical resonators relevant for this thesis. Chapter 2 provides the basics of the theoretical background of optomechanics. The Hamiltonian...

A large number of stakeholders exist in the modern air traffic management ecosystem. Air transportation studies benefit from collaboration and the sharing of knowledge and findings between these different players. However, not all parties have equal access to information. Due to the lack of open-source tools and models, it is not always possible...

This study explores the influence of the wave characteristics on the attenuation process of waves through coastal mangroves, which are threatened by the coastal mangrove squeeze phenomenon. Coastal mangrove squeeze is the phenomenon where coastal regions, even when sediment availability is sufficient, are eroding due to a lack of accommodation...

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...

Photovoltaic (PV) solar energy is variable and not completely predictable; therefore, different energy storage devices have been researched. Among the variety of options, electrochemical cells (commonly called batteries) are technically feasible because of their maturity and stability. However, PV-battery systems face multiple challenges such as...
