This work deals the application of the artificial immune system to discriminate between healthy and people with Parkinson’s disease (PWP). As the symptoms of Parkinson’s disease (PD) occur gradually and mostly targeting the elderly people for whom physical visits to the clinic are inconvenient and costly, telemonitoring of the disease using measurements of dysphonia (vocal features) has a vital...

Bio: Christopher Wee is a Researcher in the Computer Security Group at the University of California, Davis, Computer Science Department. His current research interests are intrusion detection, security auditing and Formal policy specifications. Chris has participated in three intrusion detection systems projects: DIDS, a LAN intrusion detection system, GrIDS: a wide-area IDS, and LAFS: a file-s...

Geometry is not only a part of mathematics with ancient roots but also a vivid area of modern research. Especially the field of geometry, called by some negligence “elementary”, continues to attract the attention also of the great community of leisure mathematicians. This is probably due to the small set of prerequisites necessary to formulate the problems posed in this area and the erudition a...

In recent years the Monte Carlo tree search revolution has spread from computer Go to many areas, including computer Hex. MCTS Hex players now outperform traditional knowledge-based alpha-beta search players, and the reigning Computer Olympiad Hex gold medallist is the MCTS player MoHex. In this paper we show how to strengthen MoHex, and observe that — as in computer Go — using learned patterns...

In this paper we describe the network infrastructure we designed, built and operated for the International Mathematics Olympiad in the Netherlands in 2011. The infrastructure was pragmatically designed around OpenVPN tunnels in a star topology between the various venues. VLANs were extensively used to separate functional groups and networks. The actual construction of the event network took abo...

The YAM-BIO ontology alignment system is an extension of YAM++ but dedicated to aligning biomedical ontologies. YAM++ has successfully participated in several editions of the Ontology Alignment Evaluation Initiative (OAEI) between 2011 and 2013, but this is the first participation of YAM-BIO. The biomedical extension includes a new component that uses existing mappings between multiple biomedic...

Lagrange multipliers offer a way to find the extrema of an objective function f(x1, x2, . . . , xn) subject to a constraint function g(x1, x2, . . . , xn) = 0; for example, we may wish to maximize a+ b+ c subject to a2 + b2 + c2 = 1. However, there are lots of tiny details that need to be checked in order to completely solve a problem with Lagrange multipliers. On an olympiad the use of Lagrang...

What is it that we want to achieve with our Linguistic Olympiads and how do the contests vary in different countries? The Swedish Olympiad has been running for 7 years now and is primarily focused on public outreach spreading linguistics to secondary school students. The contest involves not only a test but also lectures, school visits and teaching material. The effort is put on promoting the i...
