A wide range of transport bilevel problems are investigated referring to an elementary network consisting of one Origin Destination (OD) pair, with a given demand, connected by two links. In this context it is shown that these problems, generally non-convex, exhibit several local minima. Most results are supplied in a graphical form and analytical proofs are developed for the NDP with linear in...

We will discuss the problem of multiplexing variable-rate IP-streams onto shared cellular links, which is usually more difficult than performing resource allocation in fixed networks due to the timevarying and location-dependent nature of the wireless channel. Hence, we will show that simple schemes, if they are not supplied with additional link status information, do not yield acceptable resul...

UNLABELLED MaxLink, a guilt-by-association network search algorithm, has been made available as a web resource and a stand-alone version. Based on a user-supplied list of query genes, MaxLink identifies and ranks genes that are tightly linked to the query list. This functionality can be used to predict potential disease genes from an initial set of genes with known association to a disease. The...

Due to the success of new multimedia technologies, there is a great interest for providing a resource allocation strategy suitable for multimedia applications. Many solutions proposed in literature are based on proportional share resource allocation, such as WFQ, WF2Q, EEVDF, or SFQ. In a previous paper, we showed how to perform resource reservation according to a Constant Bandwidth allocation....

INTRODUCTION Primary care providers have limited time for physical activity counseling. They can optimize counseling time by referring patients to community resources for more comprehensive support. To facilitate referrals, resource guides (lists of community opportunities with descriptive information) are often created but seldom used. We elicited the detailed opinions of providers about how t...

OBJECTIVE This project aimed to develop an open-access on-line resource to assist health care professionals in providing effective feedback on patient-centered clinical and communication skills. The collaborative nature of the development of this learning resource is outlined and evaluation of its use is discussed. METHODS An inter-professional team of teaching staff from two London Universit...
