There exist two formulations of rough sets: the conceptual and computational one. The conceptual or semantical approach of rough set theory focuses on the meaning and interpretation of concepts, while algorithms to compute those concepts are studied in the computational formulation. However, the research on the former is rather limited. In this paper, we focus on a semantically sound approach o...

In this paper, a variable-precision dominance-based rough set approach (VP-DRSA) is proposed together with several VP-DRSA-based approaches to attribute reduction. The properties of VP-DRSA are shown in comparison to previous dominance-based rough set approaches. An advantage of VP-DRSA over variable-consistency dominance-based rough set approach in decision rule induction is emphasized. Some r...

Resistance to Meloidogyne spp. in commonly used resistant grape rootstocks is slightly compromised at soil temperatures above 27°C. Newly released UCD-GRN series rootstocks, which have broad nematode resistance, exhibit trace infections by Meloidogyne spp. at elevated temperature. Pathotypes of M. incognita and M. arenaria that are virulent on 'Harmony' rootstock, as well as M. incognita Race 3...

The aim of this paper is to explore and evaluate the role that can be played by Usability Maturity Models (UMMs) in integrating agile processes and User Centred Design (UCD). UMMs can be utilised in Agile projects as a diagnostic tool to assess the extent to which UCD is systematically and consistently implemented and the extent of effective implementation of UCD in development projects. This p...

BACKGROUND Nutrition and diet apps represent today a popular area of mobile health (mHealth), offering the possibility of delivering behavior change (BC) interventions for healthy eating and weight management in a scalable and cost-effective way. However, if commercial apps for pediatric weight management fail to retain users because of a lack of theoretical background and evidence-based conten...

Background • Therapies for rare diseases have ignited industry-wide debates concerning patient access, pricing and efficacy. Urea cycle disorders (UCD), a genetic rare disease, is a target for enzyme replacement therapies, yet UCD epidemiology data are scarce. For payers and pharmaceutical companies to accurately forecast patient cost of care, accurate patient population estimates are a necessi...

The info information retrieval system was designed and developed for the XXVII Olympic Summer Games held in Sydney, Australia in September 2000. info provided journalistsandbroadcasterswith informationforplanningtheirdaysat thegamesandproducing their coverage of Olympic events. The user-centered design (UCD) team from the IBM Storage Systems Group was invited to work with the info system for th...

Testing plays a major role for improving the quality of a software product. Due to its iterative and incremental nature it needs special attention. Test case generation is one of the complex activities carried out during testing phase. Generating test cases in the early phases of development life cycle works like a catalyst for model based testing and at the same time efficiently manages time a...
