UNLABELLED Functional techniques are playing a pivotal role in the imaging of cancer today. Our aim was to compare, on a head-to-head basis, 3 functional imaging techniques in patients with histologically verified neuroendocrine tumors: somatostatin receptor scintigraphy (SRS) with (111)In-diethylenetriaminepentaacetic acid-octreotide, scintigraphy with(More)
Tailorability is generally regarded as a key requirement for groupware applications. In this paper, we will focus on a specific class of tailoring activities: the definition of different system behaviour for specific scopes of validity. Since the state of the art in the CSCW literature does not yet offer any satisfactory solutions to support users in(More)
AIM Limited therapeutic options have highlighted the demand for new treatment modalities for patients with advanced neuroendocrine tumors (NET). Promising results of initial studies have warranted the implementation of peptide receptor radionuclide therapy (PRRT) in clinical practice. However, this treatment option still needs clinical evaluation. METHODS(More)
In groupware tools, the activation of a function may affect other users who might have conflicting interests. We developed technical mechanisms to support users in resolving them. Contrary to current implementations of groupware tools, these mechanisms strengthen the position of the users who are affected by the activation of said functions. Supporting the(More)
This thesis gives some background on the use of Artificial Intelligence techniques in game development, notably reinforcement learning techniques implemented to allow games to learn to play and improve via selfplay, or playing against a human opponent and artificial neural networks used in the decision making process of ingame agents. Some of these ideas(More)
Peptide receptor radionuclide therapy (PRRT) is a relatively new mode of internally targeted radiotherapy currently in clinical trials. In PRRT, ionizing radioisotopes conjugated to somatostatin analogues are targeted to neuroendocrine tumors (NETs) via somatostatin receptors. Despite promising clinical results, very little is known about the mechanism of(More)
This Paper introduces a Model Based Predictive Controller to control simultaneous boost pressure and EGR-rate at a diesel engine [5]. In the course of the project " ATECS " (Advanced Truck Engine Control System), founded by the European Community, a non-linear simulation model of truck diesel engine in Matlab/Simulink ® was developed by the Institute of(More)
