BACKGROUND AND PURPOSE Understanding underlying gait characteristics during performance of the Dynamic Gait Index (DGI) could potentially guide interventions. The purpose of this study was to describe the characteristics and reliability of gait performance during the level walking items of the DGI in people with balance or vestibular dysfunction. The study was a cross-sectional investigation wi...

The large diversity of applications and requirements posed to current network environments make the resource allocation problem difficult to work out. This paper proposes a dynamic algorithm based on weighted fair queueing (WFQ) to promote fairness (in the Rawlsian sense) and efficiency (in the Paretian sense) in the allocation of bandwidth for multi-application networks. Utility functions are ...

In this paper, we consider a beyond-5G scenario, where two types of users, denoted as scheduled and uncoordinated nodes, coexist on the same set of radio resources for sending data to a base station. Scheduled nodes rely solely on a centralized scheduler within the base station for the assignment of resources, while uncoordinated nodes use an unslotted Carrier Sense Multiple Access (CSMA) proto...

Fair scheduling or Fair Queueing (FQ) algorithms have received much attention in recent years because of their ability to provide a wide range of Quality-ofService (QoS) guarantees to end users. In this paper, we present a new analysis method that can statistically model such fair scheduling algorithms under Poisson arrivals and a general packet length distribution. We coin the new term M/G/FQ ...

This article reports the results of a content analysis of 23 direct-to-consumer (DTC) product-specific television prescription drug advertisements broadcast during 2001. A majority of ads used both medical and lay terms to convey medical ideas. Most gave consumers somewhat more time to absorb facts about benefits than those about risks, which could have implications for the "fair balance" requi...

Ensuring fairness in a system with scarce, preferred resources requires time sharing. We consider a heterogeneous system with a few “big” and many “small” processors. We allocate heterogeneous processors using a novel token mechanism, which frames the allocation problem as a repeated game. At each round, users request big processors and spend a token if their request is granted. We analyze the ...

Several routing protocols have been proposed to maximize the sensor networks lifetime. However, most of these solutions try to find an energy efficient path and don’t account for energy consumption balancing in sensor network. This usually leads to network partitioning. The aim of this paper is to evaluate, analyze and compare three routing protocols (EAR, FEAR and BEER) that balance energy con...

We present an efficient implementation of a fair e-cash protocol especially designed for mobile wireless environments. Our protocol attempts to offer a reasonable balance between the anonymity feature on one side, and the possibility of revoking that anonymity in case that there exist reasonable doubts about the behavior of a given user. Our system considers two protocols especially designed fo...

changes in credit risk may arise when either the value or the risk of corporate assets changes. changes in the equity value associated with the changes in the asset value and changes in asset risk can be characterized into potentially countervailing direct and indirect effects. the indirect effect of risk on equity value is a function of factors that affect the debt value of including leverage,...

networks attempts to balance the trade-off between fairness and channel utilization. In this paper, we first propose a topology-independent methodology to predict maximum achievable channel utilization under fairness constraint by two performance bounds. Based on the notion of bottlenecks introduced in prediction, we design a centralized and improved fair scheduling algorithm for wireless ad-ho...
