This paper studies the applicability of Synthetic Environments (SE) for dynamic prototyping in the early phase of product design. For this purpose, a simple SE, built with commercial off-the-shelf (COTS) technology, was employed to support the design of the lid of an X-Ray machine. Psychological experiments, statistical analysis of questionnaires, and user interviews indicated that for the desi...

For decision problems Π(B) defined over Boolean circuits using gates from a restricted set B only, we have Π(B) ≤AC 0 m Π(B ) for all finite sets B and B of gates such that all gates from B can be computed by circuits over gates from B. In this note, we show that a weaker version of this statement holds for decision problems defined over Boolean formulae, namely that Π(B) ≤NC 2 m Π(B ∪ {∧,∨}) a...

7 Persistent scatterers synthetic aperture radar interferometry (PSI) analysis is viewed as a 8 promising monitoring technique for multiyear detection of ground surface displacements 9 during long term CO2 injection into deep aquifers (of the order of 25 to 50 years). 10 This technique was successfully utilized at the CO2 storage site of In-Salah (Algeria). 11 Nevertheless, this success may not...

INTRODUCTION Competency means the capacity to make responsible and balanced decisions. This may be performed in clinical settings (decision-making abilities on treatment or risky diagnostic procedures) and also in daily-life activities (financial matters, nursing home admittance, contracts, etc.). Competency is linked to the ethical principle of autonomy and to a horizontal doctor-patient inter...

Baldwin et al. (2007 [this issue]) raise a number of concerns about our efforts to discern the independent effects of human activity levels and distributions on biodiversity (Brown & Laband 2006). Their central point of contention seems to be that we failed to acknowledge properly in our work that “land-use change due to sprawl is a leading threat to biological diversity in the United States.” ...

Pure graphene in the form of few-layer graphene (FLG) - 1 to 6 layers - is biocompatible and non-cytotoxic. This makes FLG an ideal material to incorporate into dental polymers to increase their strength and durability. It is well known that graphene has high mechanical strength and has been shown to enhance the mechanical, physical and chemical properties of biomaterials. However, for commerci...

An important issue that needs to be addressed when using association rules is the validity of the rules for new situations. Rules are typically derived from the patterns in a particular dataset. When the conditions under which the dataset has been obtained change, a new situation is said to have risen. Since the conditions existing at the time of observation could aaect the observed data, a cha...

In this paper we present the design, applicability and preliminary experimental results of the network redirection layer developed at the University of Freiburg as part of Plexor, a load-balancing and fault-tolerance middleware framework. The non-invasive nature of our layer allows all dynamically-linked network applications to beneet from our framework without the need to recompile them, which...

The aim of this paper is to assess the applicability of repeaters for downlink capacity improvement in hotspots through field measurements. Deployment of repeaters in capacity-limited scenarios requires more careful radio network planning compared to the traditional approach for operation in coverage-limited environment. The results of the field measurements conducted in an urban UMTS network r...

This document describes the applicability of Multiprotocol Label Switching (MPLS) to traffic engineering in IP networks. Special considerations for deployment of MPLS for traffic engineering in operational contexts are discussed and the limitations of the MPLS approach to traffic engineering are highlighted. Boyle, et al. Informational [Page 1] RFC 3346 Applicability Statement for Traffic Engin...
