Abstract:
This thesis is titled The influence of a nonlinear Power Take Off on a Wave Energy Converter. It looks at the effect that having a nonlinear Power Take Off (PTO) has on an inertial referenced, slack moored, point absorber, Wave Energy Converter (WEC). The generic device studied utilizes relative heave motion between an axi-symmetric cylinder and an internal mass, for the PTO to operate between. The PTO is the part of the WEC that transforms the relative motion into electricity. In this work, three different types of nonlinear PTO and a linear PTO are presented, tested, analysed and compared. T

The dropped objects are identified as one of the top ten causes of fatalities and serious injuries in the oil and gas industry. It is of importance to understand dynamics of dropped objects under water in order to accurately predict the motion of dropped objects and protect the underwater structures and facilities from being damaged. In this thesis, we study nondimensionalization of dynamic equations of dropped cylindrical objects. Nondimensionalization helps to reduce the number of free parameters, identify the relative size of effects of parameters, and gain a deeper insight of the essential

Autonomous driving is a disrupting technology that is expected to reshape transportation systems. The benefits of autonomous vehicles include, but are not limited to, safer transportation, increased economic growth, and broader access to mobility services. Industry and academia are currently researching a variety of topics related to autonomous driving, however, the focus seems to be on passenger vehicles. As a consequence, heavy-duty vehicles, which are a significant share of transportation systems, are overlooked, and the challenges associated with these vehicles are neglected. This thesis s

Abstract:
Autonomous driving has been an important topic of research in recent years. In this thesis we study its application to Heavy Duty Vehicles, more specically, vehicles consisting of a truck and a trailer. An overview study is done on three fundamental steps of an autonomous driving system, planning, trajectory tracking and obstacle avoidance. In the planning part, we use RRT, and two other variants of the algorithm to nd trajectories in an unstructured environment, e.g., a mining site. A novel path optimization post-processing technique well suited for use with RRT solutions was also developed.

Abstract:
Design of heavy earthmoving equipment is based primarily on feedback from drivers. Most design studies on ingress and egress focus on the motion itself and rely heavily on experimental data. This process requires physical construction of expensive (in terms of time and money) mockups before any feedback can be obtained. Post-feedback design changes and the analysis of those changes are again expensive processes. Although the design of heavy vehicles requires consideration of human safety and comfort, very little attention has been given to simulating ingress and egress movement for these vehic

Abstract:
Ship roll motion has been the subject of many studies, because of the complexities associated with this mode of ship motion, and its impact on operability, safety, and survivability. Estimation and prediction of the energy transfer and dissipation of the hydrodynamic components, added inertia and damping, is essential to accurately describe the roll motions of a ship. This is especially true for ship operations in moderate to extreme sea conditions. In these conditions, a complex process of energy transfer occurs, which alters the physical behavior of the hydrodynamic components, and ultimatel

The steering dynamics, from steering wheel via wheel angles, to a measurable vehicle curvature, is modeled, and a conversion from desired curvature gain to input angle to the steering wheel is derived.

Abstract:
In my dissertation, I discuss three of Akın’s feature films: Im Juli (In July, 2000), Gegen die Wand (Head-On, 2004), and Auf der anderen Seite (The Edge of Heaven, 2007) in order to investigate Akın’s filmic visions of Europe. Through close textual readings, I analyze three aspects of his films in particular: the spatial conceptions of Europe (city- and landscapes), the sounds of Europe (music and languages) as well as the display of ethnic minorities and the changing urban demography in Germany and Europe. I argue that Akın employs an “aesthetic of heterogeneity” to portray his filmic Europe

Abstract:
The following research has focused on the utility of Ulva as an indicator of seawater nitrogen loading. Evaluation was made in three ways: 1) Observation of large-scale geographic variation in nitrogen status in natural populations around New Zealand in summer and winter, 2) Laboratory-based experimental assessment of the biochemical responses of N-indices in Ulva to nitrogen enrichment, and 3) Culturing standardized test-Ulva under low nutrient conditions which could be deployed into a variety of field situations.

Abstract:
While decision-making under uncertainty is a major universal problem, its implications in the field of transportation systems are especially enormous; where the benefits of right decisions are tremendous, the consequences of wrong ones are potentially disastrous. In the realm of highway systems, decisions related to the highway configuration (number of lanes, right of way, etc.) need to incorporate both the traffic demand and land price uncertainties. In the literature, these uncertainties have generally been modeled using the Geometric Brownian Motion (GBM) process, which has been used extens
