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...

Community multimedia centers in Mozambique : exploring and experimenting co-design

Cumbula, Salomão David ; Cantoni, Lorenzo (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2017 ; 2017COM002.

The overall aim of this doctoral thesis was to elucidate the premises and conditions in which a co-design approach can be used with rural communities in Mozambique and the usage of Information and communication technologies for development as a tool for supporting rural communities on daily activities. The doctoral thesis includes five papers, a systematic literature review, and four case...

Software redundancy : what, where, how

Mattavelli, Andrea ; Pezzè, Mauro (Dir.) ; Carzaniga, Antonio (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2016 ; 2016INFO007.

Software systems have become pervasive in everyday life and are the core component of many crucial activities. An inadequate level of reliability may determine the commercial failure of a software product. Still, despite the commitment and the rigorous verification processes employed by developers, software is deployed with faults. To increase the reliability of software systems, researchers...

On the hausdorff and other cluster Voronoi diagrams

Khramtcova, Elena ; Papadopoulou, Evanthia (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2016 ; 2016INFO005.

The Voronoi diagram is a fundamental geometric structure that encodes proximity information. Given a set of geometric objects, called sites, their Voronoi diagram is a subdivision of the underlying space into maximal regions, such that all points within one region have the same nearest site. Problems in diverse application domains (such as VLSI CAD, robotics, facility location, etc.) demand...

Essays on variance risk

Gruber, Peter ; Trojani, Fabio (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2015 ; 2015ECO010.

My PhD thesis consists of three papers which study the nature, structure, dynamics and price of variance risks. As tool I make use of multivariate affine jump-diffusion models with matrix-valued state spaces. The first chapter proposes a new three-factor model for index option pricing. A core feature of the model are unspanned skewness and term structure effects, i.e., it is possible that the...

Space and process : the organizational importance of what we leave behind

Petani, Fabio James ; Mengis, Jeanne (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2016 ; 2016COM013.

Organizational research recently advocated an attention to space (Kornberger & Clegg, 2004), examining how space both produces and is produced by complex relationships of materiality, identity and power (Dale & Burrell, 2008). This literature widely turned to the founding book The Production of Space by Henri Lefebvre (1991/1974) to show how organizational practices resist (Wasserman &...

A comprehensive approach to MPSoC security : achieving network-on-chip security : a hierarchical, multi-agent approach

Lukovic, Slobodan ; Sami, Mariagiovanna (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2012 ; 2012INFO005.

Multiprocessor Systems-on-Chip (MPSoCs) are pervading our lives, acquiring ever increasing relevance in a large number of applications, including even safety-critical ones. MPSoCs, are becoming increasingly complex and heterogeneous; the Networks on Chip (NoC paradigm has been introduced to support scalable on-chip communication, and (in some cases) even with reconfigurability support. The ...
