Background: Balance disorder is one of the most-studied fields in low-back pain patients (LBP). However, there isinsufficient information regarding the effect of LBP subgrouping on postural control. The purpose of the present studywas to compare postural control between subgroups of chronic nonspecific LBP and healthy subjects during lifting.Methods: A total of 35 men with chronic LBP (19 activ...

Mobile wireless networks provide a robust capability for information sharing and play a vital role in supporting communications requirements in collaborative networks. Stimulating participation and sharing available resources are critical issues for nodes within collaborative networks. Resource allocation models that incorporate incentives enable use of available resources while, at the same ti...

Actual home networks have become an heterogeneous environment in terms of technologies used and do not take into account any intelligent energy saving mechanism. In this paper we propose an energy saving strategy by integrating a Wireless Sensor Network (WSN) with a high speed, hybrid home network. The main objective is to demonstrate that a WSN can act as a dependable control plane, where low ...

We are studying some fundamental properties of the interface between control and data planes in Information-Centric Networks.We try to evaluate the traffic between these two planes based on allowing a minimum level of acceptable distortion in the network state representation in the control plane. We apply our framework to content distribution, and see how we can compute the overhead of maintain...

Whether driven by security concerns, need for flexibility, deployment of advanced services or as a simplified outsourcing model, overlaying a virtual service topology over the underlying network infrastructure is common. To ensure and enforce consistent service quality, fairness and protocol behavior it is necessary to measure and monitor these service level topologies. In this paper we present...

This document describes terminology for the benchmarking of devices that implement traffic control using packet classification based on defined criteria. The terminology is to be applied to measurements made on the data plane to evaluate IP traffic control mechanisms. Rules for packet classification can be based on any field in the IP header, such as the Differentiated Services Code Point (DSCP...

Software Defined Networking (SDN) defines a network architecture in which the control plane is managed by a logically centralized controller, and thus configuration updates occur frequently. We have recently introduced an approach that uses time-based configuration updates, allowing to simplify complex update procedures and to minimize transient effects caused by configuration changes. This pap...

Many robust control problems can be formulated in abstract form as convex feasibility programs, where one seeks a solution x that satisfies a set of inequalities of the form F . = {f (x, ) 0, ∈ D}. This set typically contains an infinite and uncountable number of inequalities, and it has been proved that the related robust feasibility problem is numerically hard to solve in general. In this pap...

The commoditization of key processing components coupled with virtualization of infrastructure functions will lead to a radical change in the economics of mobile networks. The latter will help network providers (e.g., MNO, MVNO) move from proprietary hardware and software platforms towards open and flexible cellular systems based on general-purpose cloud infrastructures. In this context, 5G sys...

The application of an IP-based control plane to optical networks has opened up new opportunities and challenges for network designers. Although much work has been done on standardization of protocols for IP networks, the applicability of these protocols to controlling optical networks and the overall reliability of optical networks needs further investigation. This paper provides a detailed dis...
