Terrain Impostors
… software applications which need to render large terrain meshes can suffer from slow frame rates if the geometry of the terrain is sufficiently dense. However, the viewing angle to many distant features of the terrain does not change rapidly with respect to time. If the movement of the viewing …

Human Terrain Teams
… lessons from the U.S. Army's Human Terrain Teams. In the past, the Human Terrain Teams have been the topic of various debates, but none discussed their performance. Studying what influences how Human Terrain Teams perform is important to the National Security System to improve its …

Rupturing the terrain vague
This thesis started with the above statement made by Jean Nouvel in conversation with Jean Baudrillard on the metamorphosis of architecture. This project set out as both a manifestation of the above philosophy, using it as an approach towards making architecture, and as an exploration to test …

Fast, realistic terrain synthesis
The authoring of realistic terrain models is necessary to generate immersive virtual environments for computer games and film visual effects. However, creating these landscapes is difficult - it usually involves an artist spending many hours sculpting a model in a 3D design program. Specialised …

Remaking the terrain vague
This paper serves as a pretext to the resulting architectural project and traces the progression of the design process born from the entry point of this thesis, of a site. It portrays an attempt to conceive a considered methodology for approaching architectural design. Thus this dissertation traces …

Improved Terrain Measurement System for Estimation of Global Terrain Features, Surface Roughness, and Texture
… improvements in accuracy and repeatability of terrain measurement systems. Traditional terrain measurement systems are tailored for a measuring a specific scale and resolution and hence application scope. These systems tend to focus on surface roughness alone and reject either fine macrotexture …

The G.A.A. a Contested Terrain
The Gaelic Athletic Association (GAA) as an organisation grew from an idealised political ideology prevailing in nationalist Irish politics. Coupled with the Home Rule movement in which the right of alien governments having any constitutional right to interfere and infringe on the borders of …

Distributed texture-based terrain synthesis
Terrain synthesis is an important field of Computer Graphics that deals with the generation of 3D landscape models for use in virtual environments. The field has evolved to a stage where large and even infinite landscapes can be generated in realtime. However, user control of the generation process …

Learning Robust Terrain-Aware Locomotion
… walk over a diverse set of natural and complex terrains. Approaches to locomotion based on model-based feedback control are robust to perturbations but cannot easily incorporate visual terrain information. Meanwhile, approaches to locomotion based on learning excel at associating visual sensory …

Terrain and Vehicle-Terrain Sensing and Estimation in Real-Time for Use in Autonomous Vehicles
… applications for autonomy in off-road scenarios terrain, such as in military and agriculture, most autonomous models focus on on-road applications and do not account for the effect of deformable terrains. This project focuses on obtaining information about vehicle-terrain interaction in …

Development of a Terrain Pre-filtering Technique applicable to Probabilistic Terrain using Constraint Mode Tire Model
The vertical force generated from terrain-tire interaction has long been of interest for vehicle dynamic simulations and chassis development. As the terrain serves as the main excitation to the suspension system through pneumatic tire, proper terrain and tire models are required to produce reliable …

Computer generation and rendering of terrain
Computer Generation and Rendering of Terrain explores different techniques that are currently used in computer science to generate terrain data. Also explored are some techniques for rendering the terrain on a computer display. A new three step technique for the generation of terrain that is based …

Robust bipedal locomotion on unknown terrain
… of general schemes enabling the robots to reject terrain disturbances. In this thesis, two approaches are presented to enhance the performance of bipedal robots walking on modest terrain. The first approach searches for a walking gait that is intrinsically easily stabilized. The second approach …

Event Detection in the Terrain Surface
Event Detection is a process of identifying terrain flatness from which localized events such as potholes in the terrain surface can be found and is an important tool in pavement health monitoring and vehicle performance inspection. Repeated detection of terrain surfaces over an extended period of …

Improving the Quality of Terrain Measurement
… and tire models has raised the requirements for terrain measurement capabilities. Inaccuracies that were once tolerable for measurement of general terrain roughness are no longer acceptable for these new applications. The techniques in this work seek to improve the quality of terrain measurement …

Terrain-relative navigation for autonomous underwater vehicles
… and applications. This thesis presents a terrain-relative navigation system for AUVs that does not require the deployment of acoustic beacons or other navigational aids, but instead depends on a supplied digital bathymetric map and the ability of the vehicle to image the seafloor. At each …

BOLTZMANN ENTROPY FOR UNDERSEA TERRAIN AIDED NAVIGATION
… explores the ability to improve Undersea Terrain Aided Navigation (UTAN) with respect to coverage path planning and creates a robust coverage path planning algorithm utilizing a new paradigm in configuration entropy. It highlights a classic challenge in the path planning problem between …
