Augmenting an existing network with additional links to achieve higher robustness and survivability plays an important role in network design. We consider the problem of augmenting a network with links of minimum total cost in order to make it edge-biconnected, i.e. the failure of a single link will never disconnect any two nodes. A new evolutionary algorithm is proposed that works directly on ...

Study objective: To investigate age, period, and cohort effects on functional status. Design: A prospective cohort study with measurements in 1981, 1990, and 1996. Setting: Three municipalities in north east Finland. Participants: A regionally representative sample of 19 to 63 year old men and women was drawn from the census data in 1979, of which 758 men and 1033 women initially aged 39–63 yea...

We propose an extension of Stabler’s version of clitics treatment for a wider coverage of the french language. For this, we present the lexical entries needed in the lexicon. Then, we show the recognition of complex syntactic phenomenae as (left and right) dislocation, clitic climbing over modal and extraction from determiner phrase. The aim of this presentation is the syntaxsemantic interface ...

Classification Association Rule Mining (CARM) systems operate by applying an Association Rule Mining (ARM) method to obtain classification rules from a training set of previously-classified data. The rules thus generated will be influenced by the choice of ARM parameters employed by the algorithm (typically support and confidence threshold values). In this paper we examine the effect that this ...

We present a hill-climbing algorithm to solve planning problems with temporal uncertainty. First an optimistic plan that is valid when all actions complete quickly is found. Then temporal reasoning techniques are used to determine when the plan may fail. At time points that cause an unsafe situation, contingency branches are inserted. We describe our planner PHOCUS-HC, give preliminary results,...

Abstract This chapter presents a novel research collaboration between architects and computer scientists to investigate and develop mobile, context-sensitive serious games for sports and health (so-called exergames). Specifically, it describes a new approach that aims to design exergames which interact with the player’s built, topographic, and social environment in a meaningful way and presents...

4 Lightweight wheelchair stair-climbing attachments. Step stair-climbing mechanism targeted for wheelchair application is presented in Section 3. Finally a.This paper focuses on presenting the development of a stair-climbing wheelchair mechanism with high single-step capability. The mechanism is based on front.A stair climbing mechanism is a semi-automated vehicle, which has the. One is for mak...
