Context orescence imaging microscopy, national metrology institutes [3], microscope manufacturers [4], and more recently core facilities [5] have gotten involved in identifying, manufacturing and/or testing different tools, both hardware and software, to assess the numerous aspects of fluorescence microscopes. On the one hand, for the core facilities, it has become obvious that quality control ...

crested wheatgrass (agropyron cristatum (l.) gaertner.) is a potential source of low-maintenance turf species for use in areas with less water. the main goal of this study was to evaluate turf quality characteristics of 24 crested wheatgrass specimens collected from different locations of iran as low-maintenance turfgrass. the experimental design was a randomized complete block design with 3 re...

The assurance of power quality depends on factors which influence the performances of the availability: the reliability and its support – the maintenance. This paper deals with the interactions between the indicators of reliability, maintenance, availability and with the methods for the calculation of the reliability indicators. For an overhead line of 110 kV the characteristics of the reliabil...

Wireless sensor networks are adapted to monitoring applications. Specific solutions have to be developed for industrial environments in order to deal with the harsh radio conditions and the QoS (quality of service) requirements of industrial applications. In this paper, we present the main protocols used in the OCARI project, and we describe their use of cross-layering techniques. We show how i...

Model-based performance predictions and reconfigurations enable optimizing resource efficiency while ensuring that Quality-of-Service demands are met in today’s complex ITsystems. The Descartes Modeling Language (DML) and the Palladio Component Model (PCM) are two architectural performance modeling formalisms applied in this context. This paper compares DML to PCM concerning similarities, diffe...

Mannion and Davies’ article recognises whistleblowing as an important means of identifying quality and safety issues in healthcare organisations. While ‘voice’ is a useful lens through which to examine whistleblowing, it also obscures a shifting pattern of uncertain ‘truths.’ By contextualising cultures which support or impede whislteblowing at an organisational level, two issues are overlooked...

This paper presents a brief review of some existing correlation models which attempt to map Quality of Service (QoS) to Quality of Experience (QoE) for multimedia services. The term QoS refers to deterministic network behaviour, so that data can be transported with a minimum of packet loss, delay and maximum bandwidth. QoE is a subjective measure that involves human dimensions; it ties together...

Based on the expectancy disconfirmation theory, this study proposes a decomposed technology acceptance model in the context of an e-learning service. In the proposed model, the perceived performance component is decomposed into perceived quality and perceived usability. A sample of 172 respondents took part in this study. The results suggest that users’ continuance intention is determined by sa...
