Local problems are a low research priority

Online Priority Steiner Tree Problems

A central issue in the design of modern communication networks is the provision of Quality-of-Service (QoS) guarantees at the presence of heterogeneous users. For instance, in QoS multicasting, a source needs to efficiently transmit a message to a set of receivers, each requiring support at a different QoS level (e.g., bandwidth). This can be formulated as the Priority Steiner tree problem: Her...

Injury research advocacy a high priority.

Local Annihilation Method ‎and‎ Some Stiff ‎Problems

In this article‎, ‎a new scheme inspired from collocation method is‎ ‎presented for numerical solution of stiff initial-value problems and Fredholm integral equations of the first kind based on the derivatives of residual function‎. ‎Then‎, ‎the error analysis‎ ‎of this method is investigated by presenting an error bound‎. ‎Numerical comparisons indicate that the‎ ‎presented method yields accur...

Concussion research: a public health priority.

Head injury is a major public health concern due to the high incidence and the accompanying morbidity and mortality. In the USA, head injuries are a contributing factor to one third (30.5%) of all injury-related deaths and result in 52 000 deaths, 275 000 hospitalisations and 1.4 million emergency department visits each year. While fully 75% of head injuries are classified as mild traumatic bra...

Priority Queues Are Not Good Concurrent Priority Schedulers

The need for priority scheduling arises in many algorithms. In these algorithms, there is a dynamic pool of lightweight, unordered tasks, and some execution orders are more efficient than others. Therefore, each task is given an application-specific priority that is a heuristic measure of its importance for early scheduling, and the runtime system schedules these tasks roughly in this order. Co...
