We study the problem of query evaluation with the help of the crowd, when the value of the queried attributes is not available in the database and is also hard for the crowd to estimate. Rather than asking users directly about these attributes, we propose a novel alternative approach that first uses the crowd to dismantle the query attributes into finer related ones (whose value estimation is e...

It is inadequate to just assure the functional requirements. Quality of service (QoS) must also be satisfied. An important challenge for developing efficient Service Oriented Architecture (SOA) is to maintain the QoS attributes because of compositional and dynamical environment of SOA. It is significant to scrutinize how quality attributes are supported by SOA. However, implementation of SOA pr...

Color is commonly described in terms of the three perceptual attributes-hue, saturation, and brightness-of which only hue has a qualitative nature, saturation and brightness being of a quantitative nature. A possible reason for such a phenomenological structure of the color manifold, and its geometric representation, are discussed.

Actions can create preferences, increasing the value ascribed to commodities acquired at greater cost. This behavioural finding has been observed in a variety of species; however, the causal factors underlying the phenomenon are relatively unknown. We sought to develop a behavioural platform to examine the relationship between effort and reinforcer value in mice trained under demanding or lenie...

BACKGROUND The purpose of this study was to explore the quality attributes required for effective telemedicine encounters from the perspective of the patient. METHODS We used a multi-method (direct observation, focus groups, survey) field study to collect data from patients who had experienced telemedicine encounters. Multi-perspectives (researcher and provider) were used to interpret a rich ...

Routing information plays a vital role in Mobile Ad-hoc Network (MANET). In MANET, each node maintains routing information that assists the routing process. Routing nodes and their routing attributes are essential in determining the performance of MANET. Thus, it is necessary to obtain knowledge on routing nodes and their attributes. Keeping this in view, we have proposed a model that uses a fu...

Objective: Formalization of metrics definitions to assess CORBA component assemblies’ quality attributes. Method: Representation of a component assembly as an instantiation of the CORBA Component Model metamodel. The resulting meta-object diagram can then be traversed using Object Constraint Language clauses. These clauses are a formal and executable definition of the metrics that can be used t...

The role of landscape valuation and extended cost-benefit analysis in landscape conservation decision-making is first addressed. It is stressed that substantial research on how to value alternative conservation schemes is required, in order to cope with emerging policy needs. An analytical frame for the valuation of alternative landscape conservation schemes is then discussed. This frame enable...
