Fu, B. (author), Uhlig, S.P.W.G. (author)The evaluation of dynamic Traffic Engineering (TE) algorithms is usually carried out using some specific network(s), traffic pattern(s) and traffic engineering objective(s). As the behavior of a TE algorithm is a consequence of the interactions between the network, the traffic demand and the algorithm itself, the relevance of TE may depend on...conference paper

Li, C. (author), Wang, H. (author), Van Mieghem, P. (author)The largest eigenvalue ? 1 of the adjacency matrix powerfully characterizes dynamic processes on networks, such as virus spread and synchronization. The minimization of the spectral radius by removing a set of links (or nodes) has been shown to be an NP-complete problem. So far, the best heuristic strategy is to remove links/nodes based on the...conference paper

Blenn, N. (author), Doerr, C. (author), Van Kester, B. (author), Van Mieghem, P. (author)As Online Social Networks (OSNs) become an intensive sub- ject of research for example in computer science, networking, social sci- ences etc., a growing need for valid and useful datasets is present. The time taken to crawl the network is however introducing a bias which should be minimized. Usual ways of addressing this problem are sampling...conference paper

Nourian Ghadikolaee, P. (author), Rezvani, S. (author), Sariyildiz, I.S. (author), Van der Hoeven, F.D. (author)In a quest for promoting sustainable modes of mobility, we have revisited how feasible and suitable is it for people to walk or cycle to their destinations in a neighbourhood. We propose a few accessibility measures based on an 'Easiest Path' algorithm that provides also actual temporal distance between locations. This algorithm finds paths that...conference paper

Blenn, N. (author), Charalampidou, K. (author), Doerr, C. (author)The wide-spread popularity of online social networks and the resulting availability of data to researchers has enabled the investigation of new research questions, such as the analysis of information diffusion and how individuals are influencing opinion formation in groups. Many of these new questions however require an automatic assessment of...conference paper

Vreeburg, J.P.B. (author)After a short introduction to various types of links and network organisations, the experimental phase in military satellite communications systems is expounded in a chronological discussion of early communications satellites. This experimental phase is considered to be ended with the TASCAT and IDCSP satellites. Present systems and systems of...report 1974

Loeve, W. (author)For the aerospace laboratory NLR in the Netherlands the considerations are discussed that formed the basis of along-term plan to realize an optimal computer network. In the optimization process up to now the laboratory switched from a situation in which in each of both settlements one central close shop computer centre was available to a...report 1975

Booij, N. (author)FLOWS is a recently developed ICES subsystem for applications in the field of hydraulic engineering. It is able to compute steady as well as unsteady flows in hydraulic networks of given dimensions. This means that is does not optimize any parameters describing the network. The network may be composed of open and closed channels, reservoirs and...report 1980

Loeve, W. (author), van den Dam, R.F. (author)The NLR in the Netherlands renders scientific support and technical assistance for the design and operation of aircraft and spacecraft. The approach of NLR can be characterized by integration of experimental and theoretical investigations. For this an integrated computer and terminal network has been developed that links both NLR laboratory...report 1983

Meester, J.G. (author)Bij APT Nederland is onderzoek gedaan naar een packet switch in het SDH management netwerk. Voordat het onderzoek wordt beschreven wordt eerst het begrip SDH geïntroduceerd. Hierna wordt uitgelegd wat de functies zijn van het SDH management netwerk en hoe dit netwerk is gedefinieerd. Het onderzoek dat aan de packet switch is verricht omvat de...master thesis 1990

Gronovius, M.F. (author)Due to a combination of a market pull and a technology push a new transmission standard, called SDH (Synchronous Digital Hierarchy), has evolved. A transport network based on Digital Cross-Connect Systems, Drop & Insert Multiplexers and other SDH based products offers great network flexibility. This network flexibility can be used for the...master thesis 1990

De Boer, T. (author)The time between request and realization of private or leased lines (i.e. provisioning time) has traditionally been very long (i.e. months). To a large extent, this has to do with the inflexibility of the "conventional" transport network. With the availability of Digital Cross-connect Systems (DCS) and other network products based on the...master thesis 1991
