Efficient multi-bounce lightmap creation using GPU forward mapping

Schärfig, Randolf ; Hormann, Kai (Dir.) ; Stamminger, Marc (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2016 ; 2016INFO008.

Computer graphics can nowadays produce images in realtime that are hard to distinguish from photos of a real scene. One of the most important aspects to achieve this is the interaction of light with materials in the virtual scene. The lighting computation can be separated in two different parts. The first part is concerned with the direct illumination that is applied to all surfaces lit by a...

Connectivity of channelized sedimentary bodies : analysis and simulation strategies in subsurface modeling = Connectivité de corps sédimentaires chenalisés : stratégies d'analyse et de simulation en modélisation de subsurface

Rongier, Guillaume ; Renard, Philippe (Dir.) ; Sausse, Judith (Dir.) ; Collon, Pauline (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2016.

Channels are the main sedimentary structures for sediment transportation and deposition from the continents to the ocean floor. The significant permeability of their deposits enables fluid circulation and storage. As illustrated with turbiditic systems, those channel fill is highly heterogeneous. Combined with the spatial organization of the channels, this impacts significantly the connectivity...

Enhancing the use of entomopathogenic nematodes for biological control of root pests : from field persistence to improved shelf-life

Jaffuel, Geoffrey ; Turlings, Ted (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2016.

Agriculture is evolving towards more sustainable strategies since the application of agrochemicals and physical management of the soil have severe environmental impact and deplete soil quality. The potential of using biocontrol agents to replace or in combination with pesticides has been investigated for several decades. Entomopathogenic nematodes (EPN) are very promising in this respect. EPN are...

SoftwIre integration : an approach to service composition through distributed representations of arbitrary-length business ontologies

Ludolph, Hendrik ; Kropf, Peter (Dir.) ; Babin, Gilbert (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2016.

The demand for Software as a Service is ever increasing. With this demand comes a proliferation of third-party service offerings to fulfill it. It thus becomes crucial for organizations to find and select the right service to be integrated into their existing tool landscapes. Ideally, this is done automatically and flexibly. The objective is to always provide the best possible support to changing...

Zeitliches und räumliches Wintersturmschadrisiko in den Wäldern der Schweiz. : Bilanzierung von Waldfläche, Holzvorrat, Sturmschaden und Wettermessungen im Wandel der gesellschaftlichen Bedingungen von 1865 - 2014

Usbeck, Tilo ; Rebetez, Martine (Dir.) ; Luterbacher, Jürg (Codir.) ; Wohlgemuth, Thomas (Codir.) ; Gessler, Arthur (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2016.

The goal of this dissertation was to study winter storms as the greatest natural risk for Swiss forests on the basis of long-term data on forest development, storm damage, climate change and social transformation. In the mid-nineteenth century, winter storms began to cause noticeable damage to forests. At the same time, the administrative structures of both the Swiss Confederation and scientific...
