Realistic Rendering Of Virtual Worlds

The problem posed to the authors concerns SketchaWorld, a terrain modeling framework that allows users to easily construct virtual worlds by means of sketching. Until now, the developers of SketchaWorld have focused on procedural content generation and have left its visual presentation largely untouched. The authors have been tasked to develop a...

Using gaming as a data collection tool to design rules for agents in agent-based models - A design framework.

Agent-based modelling is a popular and suitable tool for exploring the possible states of so-called socio-technical systems. These systems consist of both technical artefacts (the physical infrastructure, e.g. pipelines), and many social artefacts (relevant actors and institutions, e.g. end-users and governments), which are intertwined with each...

The transformation of a highvoltage laboratory at the KEMA terrain in Arnhem into a museum for magical realistic art.

Between the Veluwe and the river the Rijn in the west of Arnhem is the KEMA terrein located in a park designed in beautiful english landscape architecture. The laboratories of KEMA (Keuringsdienst Elektrische Materialen Arnhem), designed in the thirties and realised in the Haagse School Stijl, are vacant these days. Our assignment was to choose...

Realistic bending stiffness of diaphragm walls for structural analysis: A comparison with the uncracked and totally cracked stiffness for the case of The Waalbrug Nijmegen

For a safe structure design standards mainly emphasize on calculations based on the uncracked and fully cracked stiffness of concrete structures. In the common design practice an uncracked stiffness (EI0) is applied for the SLS and a fully cracked stiffness (EI?) for the ULS, where the reduced stiffness EI? ? 1/3EI0. However, in reality it is...

Primary Sample Space Path Guiding

We present a scheme for unbiased path guiding. Different from existing methods that focus on constructing structures in spatial-directional domain, we work in primary sample space. We collect records containing a few dimensions of random numbers as well as the luminance that the resulting path contributes. A multiple dimensional structure is...

Alternative Representations and Techniques for Accelerated Realistic Image Synthesis: Improved Sampling, Reconstruction and Modelling Methods

Realism has always been a major goal in visual content creation - from oil painting to motion pictures, from graphic arts to scientific data visualization. Computer graphics creates a virtual reality with digital representations. Trading between accuracy and speed, realistic rendering either creates photorealistic renders that follow strict...

From Data to Prediction: Vision-Based UAV Fault Detection and Diagnosis

Despite the camera being ubiquitous to unmanned aerial vehicles (UAVs), it has not been used for fault detection and diagnosis (FDD) due to the nonexistence of UAV multi-sensor datasets that include actuator failure scenarios. This thesis proposes a knowledge-based FDD framework based on a lightweight Long-Short Term Memory network that fuses...

Het stimuleren van woningcorporaties voor middenhuur: Het formuleren en testen van financiële incentives voor woningcorporaties

Na een lange tijd waarin woningcorporaties door overheidsbeleid zijn beperkt in hun taken met betrekking tot sociale woningbouw, lijkt het belang van de woningcorporaties in het oplossen van het tekort aan middenhuur meer erkend te worden. Dit is te zien aan de recente afschaffing van de verhuurderheffing en de Nationale Prestatieafspraken met...

Fault Detection and Estimation of Fault Redundant Airspeed using Unscented Kalman Filter

Having a reliable flight envelope is of paramount importance for safe flight operations. Parameters that determine the safe flight envelope are airspeed , angle of attack, angle of sideslip, Euler angle and load factor. These parameters need to be fault redundant, In order to address this challenge, an unscented Kalman estimation routine is...
