Maldistribution of light is a potential cause of phototherapy failure in the neonate. Differences in light intensity over the surface can be measured with a radiometer as this detects the radiant energy impinging on the incubator mattress. An infant nursed on the front third of the mattress receives less than 40% of the maximal light incident on the centre of the mattress, and consequently degr...

We propose a constructive control design for stabilization of non-periodic trajectories of underactuated robots. An important example of such a system is an underactuated “dynamic walking” biped robot traversing rough or uneven terrain. The stabilization problem is inherently challenging due to the nonlinearity, open-loop instability, hybrid (impact) dynamics, and target motions which are not k...

BACKGROUND Determining eligibility for a kidney transplant is an important decision. Practice guidelines define contraindications to transplantation; however many are not evidence based. Canadian guidelines recommend that patients unlikely to survive the wait period not be evaluated. The purpose of this study was to evaluate what proportion of patients with a contraindication would survive the ...

MOOSE Crossing is a text-based virtual reality environment (or “MUD”) designed to be a constructionist learning environment for children ages 8 to 12. We performed a portfolio-style assessment of children’s programming accomplishments in this environment. Analysis of the data reveals uneven levels of achievement—some children accomplish a great deal but the majority learn little. We believe thi...

A W-containing inorganic-organic nanohybrid with a plate-like morphology has been successfully prepared through a nonaqueous synthetic route using WCl(6) as the tungsten source and benzyl alcohol as the solvent. The as-prepared hybrid nanomaterial was used directly as an efficient precursor for the formation of WO(3) nanoplates via a simple thermal treatment process. The as-obtained WO(3) mater...

Batched stream processing systems achieve higher throughput than traditional stream processing systems while providing low latency guarantee. Recently, batched stream processing systems tend to be deployed in cloud due to their requirement of elasticity and cost efficiency. However, the performance of batched stream processing systems are hardly guaranteed in cloud because static resource provi...

Mapping uneven events, such as disease cases or pollutants, is a basic but important procedure for analyzing regional relationships and variation in public health and environmental agencies. The purpose of mapping is to find out the spatial clustering of uneven events and identify spatial risk areas, which could lead to potential environmental hazards or epidemics. Meanwhile, more hypotheses co...
