Dexterous control of upper limb prostheses with multiarticulated wrists/hands is still a challenge due to the limitations myoelectric man-machine interfaces. Multiple factors limit overall performance and usability these interfaces, such as need degrees freedom sequentially not concurrently, inaccuracies in decoding user intent from weak or fatigued muscles. In this article, we developed novel ...

Abstract Effort estimation models are a fundamental tool in software management, and used as forecast for resources, constraints costs associated to development. For Free/Open Source Software (FOSS) projects, effort is especially complex: professional developers work alongside occasional, volunteer developers, so the overall (in person-months) becomes non-trivial determine. The objective of thi...

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...
