Goseling, J. (author), Gastpar, M.C. (author), Weber, J.H. (author)Leveraging recent progress in compute-and-forward we propose an approach to random access that is based on physical-layer network coding: When packets collide, it is possible to recover a linear combination of the packets at the receiver. Over many rounds of transmission, the receiver can thus obtain many linear combinations and eventually...conference paper 2013

Foumani, M. (author), Strackee, S.D. (author), Van de Giessen, M. (author), Jonges, R. (author), Blankevoort, L. (author), Streekstra, G.J. (author)Background The assessment of the joint space thickness is an important clinical parameter for diagnosing osteoarthritis. The accuracy of joint space thickness evaluation from radiographs is limited due to anatomical complexity of the wrist. We propose using distance maps estimated from 3-dimensional and 4-dimensional images reflecting joint...journal article 2013

De Ridder, J. (author), Abeel, T. (author), Michaut, M. (author), Satagopam, V.P. (author), Gehlenborg, N. (author)You finished your PhD, have been a postdoc for a while, and you start wondering, "What's next?" Suppose you come to the conclusion that you want to stay in academia, and move up the ladder to become a principal investigator (PI). How does one reach this goal given that academia is one of the most competitive environments out there? And suppose...journal article 2013

Babaei, S. (author), Hulsman, M. (author), Reinders, M.J.T. (author), De Ridder, J. (author)Background Delineating the molecular drivers of cancer, i.e. determining cancer genes and the pathways which they deregulate, is an important challenge in cancer research. In this study, we aim to identify pathways of frequently mutated genes by exploiting their network neighborhood encoded in the protein-protein interaction network. To this end...journal article 2013

Popa, M.C. (author)An increasing number of public places (e.g. cities, schools, transit districts, and public buildings) are deploying CCTV surveillance systems to monitor and protect the people in those areas. Since events like the terrorist attack in Madrid and London, there has been a further increasing demand for video sensor network systems to guarantee the...doctoral thesis 2013

(author)Pulsars with their periodic pulses and known positions are ideal beacons for navigation. The challenge, however, is the detection of the very weak pulsar signals that are submerged in noise. Radio based approaches allow the use of advanced techniques and methods for the detection and acquisition of such weak signals. In this paper, an effective...conference paper 2012

(author)Recent advances in crowd simulation techniques have led to realistic agent and group behavior through elaborate behavioral models, complex motion planning algorithms and impressive physics systems. As many crowd simulation solutions typically target only specific types of environment and scenario, a variety of special-purpose methods and systems...journal article 2012

Liu, D. (author), Blenn, N. (author), Van Mieghem, P.F.A. (author)ur society contains all types of organizations, such as companies, research groups and hobby clubs. Affliation networks, as a large and important portion of social networks, consist of individuals and their affiation relations: Two individuals are connected by a link if they belong to the same organization(s). Affliation networks naturally...journal article 2012

(author)Background Colorectal cancer (CRC) is a heterogeneous and biologically poorly understood disease. To tailor CRC treatment, it is essential to first model this heterogeneity by defining subtypes of patients with homogeneous biological and clinical characteristics and second match these subtypes to cell lines for which extensive pharmacological...journal article 2012

Liu, D. (author), Blenn, N. (author), Van Mieghem, P.F.A. (author)Social networks, as well as many other real-world networks, exhibit overlapping community structure. In this paper, we present formulas which facilitate the computation for characterizing the overlapping community structure of networks. A hypergraph representation of networks with overlapping community structure is introduced. Using the...journal article 2012

Tutenel, T. (author)The visual quality of game worlds increased massively in the last three decades. However, the closer game worlds depict reality, the more noticeable it is for gamers when objects do not behave accordingly. An important problem is that the data of a game world is often scattered across different components of the game engine. What lacks is a...doctoral thesis 2012

A distinction can be made between getting the right information and having the rights to get that information. The first is an information filtering and relevance problem, the second is a...conference paper 2012

It is, however, challenging to design for values because (1) relevant values must be identified and communicated between all stakeholders and designers and (2) stakeholders’ values differ and trade-offs must be made. We...journal article 2012

Tax, D.M.J. (author)In pattern recognition and data analysis, objects or events are often represented by a feature vector with a fixed length. For some applications this is a severe limitation, and extensions have been proposed. One approach is Multiple-Instance Learning (MIL). Here, objects are represented by a collection of feature vectors (called a bag) and a...conference paper 2012
