When designing a software system it is beneficial to study and use architectural styles from literature, to ensure certain quality attributes. However, as the interpretation of literature may differ depending on the background and area of expertise of the person reading the literature, we suggest that structured discussions about different architecture candidates provides more valuable insight ...

A model is developed that can estimate recreational welfare measures for access to and changes in quality attributes at long distance single-visited tourist sites with only on-site information available. By defining the good (a visit to the site) as indivisible in consumption welfare measures are derived by simply capturing or estimating the chokeprice(s). Stated and revealed methods suitable t...

Most inverse classification algorithms address discrete attributes and can not deal with quantitative attributes. In order to overcome the disadvantage, the discretization algorithms are applied to the inverse classification algorithms, and the main idea is: firstly, a group of feature attributes are selected by using feature selection algorithm; then, the quantitative attributes are discretize...

Most systems implement statically declared attributes for performance reasons. This paper gives a first indication that also for dynamic attributes whose implementation is not based on static declarations, performance can be very good, while offering more flexibility. Their implementation in hProlog is shown. The differences with existing systems are indicated. Small benchmarks make the claim h...

Numerous research studies have explored the effect of hypermedia on learners’ performance using Web Based Instruction (WBI). A learner’s performance is determined by their varying skills and abilities as well as various differences such as gender, cognitive style and prior knowledge. In this paper, we investigate how differences between individuals influenced learner’s performance using a hyper...

owing to the oncoming needs and increasing the population of lake urmia watershed, providing equilibrium  between water supply and demand seems quite challenging and the lake cannot be successful in meeting its ecological demands in this critical condition. in this unfavorable situation, water resources must be managed through a sustainable context. with this knowledge in hand, a multi attribut...
