Abstract:

Electrical Engineering<br>M.S.E.E.<br>In conventional centralized power systems, power is generated mostly by large synchronous generators (SGs), where the frequency of the grid depends on the rotational frequency of the prime mover. If there are any sudden changes in the load, the rotor inertia property restrains the changes in frequency and keeps the system stable. During transient periods, rotor kinetic energy of the rotor is injected into the grid to balance power supply between generation and load. With the recent high penetration of renewable energy sources (RES), the power grid is under

This research addresses some of the difficulties faced when operating voltage controlled inverters with synchronous generators in microgrids. First, an overview of microgrid value propositions is provided, and the problems faced when attempting to use microgrids to provide improved power quality are discussed. Design considerations for different types of microgrids are provided to enable microgrids to deliver the desired functionality without adding unnecessary cost. The main body of this research investigates the poor transient load sharing encountered between voltage controlled inverters and

The increasing utilisation of renewable energy sources (RESs) plays an important role in the modern power system.

The hybrid AC/DC microgrid configuration is compatible with AC power supplies, DC power supplies, AC loads and DC loads which is viewed as the most practical choice in the power system application.

Due to the high amount of time it takes to manually design virtual buildings and cities it is often desired to automate the process. Procedural modeling is a way to achieve this by algorithmically generating buildings. By using inverse generation procedural descriptions of buildings can be extracted from a given model. When using a procedural generator to create a city some variance is needed during generation which might lead to unrealistic buildings if not handled correctly.

Manually creating virtual rural worlds is often a difficult and lengthy task for artists, as plant species selection, plant distributions and water networks must be deduced such that they realistically reflect the environment being modelled. As virtual worlds grow in size and complexity, climates vary on the terrain itself and a single ecosystem is no longer sufficient to realistically model all vegetation. Consequentially, the task is only becoming more difficult for these artists. Procedural methods are extensively used in computer graphics to partially or fully automate some tasks and take

A combined view of the human brain and computer-generated virtual realities is motivated by recent developments in cognitive neuroscience and human-computer interaction (HCI). The emergence of new theories of human brain function, together with an increasing use of realistic human-computer interaction, give reason to believe that a better understanding of the relationship between human brains and virtual realities is both possible and valuable. The concept of “presence”, described as the subjective feeling of being in a place that feels real, can serve as a cornerstone concept in the developme

Abstract:

Three dimensional visualisation achieves tremendous savings in time and costs during the design process. Due to these circumstances this methods are gaining in importance. For example improvement in performance and the product security or enabling the operative optimization of a production sequence. By the virtual testing it is possible to validate a product in the whole developing process and product lifecycle. The flight simulator ATILa at Airbus Defence and Space in Friedrichshafen uses these advantages for own products. ATILa is used to test intelligent assistance systems for helicopter pi

Abstract:

Virtual reality (VR) is a medium of human interaction which is becoming more popular by the day in today's technological advancements. The applications are being developed at the same rate as the technology itself and we have only seen the start of the possible benefits it could bring society. As the technology advances it will gain a lot of trust, and the potential use cases of virtual environments will be allowed to become more complex. Already today, they often involve network streaming components which often has very strict optimization requirements in order to be able to run in real-time

Abstract:

Dieser Beitrag untersucht die These über die Existenz von Digital Natives. Die Vertreter dieser These postulieren, dass Studenten und Schüler durch den frühen Kontakt mit Informations- und Kommunikationstechnologien hinsichtlich ihres Lern-, Arbeits- und Kommunikationsverhaltens wesentlich verändert wurden. Um diese Aussage zu bewerten, werden Erfahrungen mit Virtual Collaborative Learning Veranstaltungen herangezogen. Die aktuellste durchgeführte Veranstaltung wird als Fallstudie vorgestellt und analysiert.

Abstract:

The purpose of this project was to research the virtual camera systems used in current generation third person action games and to see what could be improved upon. To do this, different camera shots were categorized into camera archetypes, which also include post process and lens effects used. Information about the games was acquired by either looking through the game’s settings or by observing gameplay. Finally the results were compared to each other as well as the film industry and several improvements regarding usage of different features and camera shots were suggested.

Abstract:

In recent years, the automotive industry has been significantly affected by a number of challenges driven by globalisation, economic fluctuations, environmental awareness and rapid technological developments. As a consequence, product lifecycles are shortening and customer demands are becoming more diverse. To survive in such a business environment, manufacturers are striving to find a costeffective solution for fast and efficient development and reconfiguration of manufacturing systems to satisfy the needs of changing markets without losses in production. Production systems within automotive
