We describe a wireless testbed composed by 24 wireless nodes that can be used to perform a broad range of studies in the area of next generation networks. This paper addresses the difficulties and constrains faced by the authors throughout the deployment process of such testbed. Flexibility and controllability were key concerns driving the testbed design. The testbed can be remotely managed thr...

This study aimed to test the effects of a psychosocial intervention, Remaking Recess, on peer engagement for children with autism spectrum disorder (ASD). Using a randomized, wait-list-controlled design, the intervention was implemented during recess at four elementary schools. The immediate treatment (IT) group consisted of 13 (2 female) elementary school students with ASD and the wait-list (W...

BACKGROUND We examined the relationship between overweight in preschool children and three environmental factors--the proximity of the children's residences to playgrounds and to fast food restaurants and the safety of the children's neighborhoods. We hypothesized that children who lived farther from playgrounds, closer to fast food restaurants, and in unsafe neighborhoods were more likely to b...

OBJECTIVE To identify correlates of objectively measured moderate and vigorous physical activity (MVPA) in children during preschool attendance. METHODS This cross-sectional study included data from 426 apparently healthy Danish children (49.5% boys), 5 to 6 years of age enrolled in 42 randomly selected preschools. The percentage of time spent in MVPA (≥ 574 counts/15 second) during preschool...

Let G = (V ,E) be a connected graph. A set U ⊆ V is convex if G[U] is connected and all vertices of V \U have at most one neighbor inU. Let σ(W) denote the unique smallest convex set that contains W ⊆ V . Two players play the following game. Consider a convex set U and call it the ‘playground.’ Initially, U = ∅. When U = V , the player to move loses the game. Otherwise, that player chooses a ve...

BACKGROUND This study investigates the influence of school playground facilities on children's daily physical activity. METHODS Participants were 594 school children measured at preschool (age 6 to 7 years) and 3 years later in third grade (518 children age 9 to 10 years) from 18 schools in 2 suburban municipalities in Denmark. Physical activity data were obtained using accelerometers. These ...

The notion of next generation networks (NGN) is based on the convergence of fixed and mobile telecommunication networks and the internet towards an all-IP environment. These NGNs support the provision of integrated information and communication services in face of increasingly becoming more complex value chains, enabled by so-called service delivery platforms (SDPs). Therefore an NGN is an envi...
