Providing Best-Effort Services in Dataspace Systems

eGovernment initiatives all over the world endeavor to integrate Information and Communication Technologies (ICT) to transform delivery of government services to their stakeholders by improving quality of services, accountability and efficiency. In this study we explore adoption of ICT to enhance government-to-employee interactions in a government organization in a developing country. We examin...

This paper deals with the impact of traffic handling mechanisms on capacity for different network architectures. Three traffic handling models are considered: per-flow, class-based and best-effort (BE). These models can be used to meet service guarantees, the major differences being in their complexity of implementations and in the quantity of network resources that must be provided. In this st...

Cellular networks, e.g. UMTS, provide voice and data services to mobile users. In hot spots where users need high speed data services operators can deploy low-cost high-speed WLANs, e.g. 802.11, to cover hot-spots. This paper proposes a possible architecture of integrating UMTS and 802.11 WLAN. The architecture allows a mobile node to maintain data (PS) connection through WLAN and voice (CS) co...

OBJECTIVES To investigate the physical demands of professional rugby league match-play using microtechnology, and to compare these demands with typical training activities used to prepare players for competition. DESIGN Prospective cohort study. METHODS Thirty elite rugby league players participated in this study. Seven hundred and eighty-six. training data sets and 104 data sets from Natio...

Does a performance measure which is a monotonous function of the benefit (a benefit measure) lead to a desirable allocation of effort between the tasks which create this benefit? We analyse two settings. If the mechanism designer knows the choice set of the agent, benefit measures generally do not result in the second-best effort allocation – unless restrictive assumptions about agent’s prefere...

In biomechanics and biorobotics, muscles are often associated with reduced movement control effort and simplified control compared to technical actuators. This is based on evidence that the non-linear muscle properties positively influence movement control. It is, however, open how to quantify the simplicity aspect of control effort and compare it between systems. Physical measures, such as ene...
