Requirements engineering (RE) is often seen as an essential facet in software development. It is a vital process before each project starts. In the context of systems engineering, an understanding and application of systems theory and practice is also relevant to RE. The contexts in which RE takes place habitually involve human activities. Therefore, RE needs to be sensitive to how people perce...

Background: Patients undergoing cardiac surgery are at increased risk of bleeding due to multifactorial coagulopathies. In the present study, we aimed at investigating the changes in platelet count and function during and after surgery as well as determining the association of the platelet dysfunction with bleeding and transfusion requirements in these patients.    Methods: A total o...

Iron, calcium, and zinc are important nutrients for the young, developing child. This study describes the usual intake of iron, calcium, and zinc among US children in the second year of life using two days of dietary intake data from the National Health and Nutrition Examination Survey 2003-2012. Estimates were calculated using PC-SIDE to account for within and between person variation. Mean us...

OBJECTIVE To signal key issues for harmonising approaches for establishing micronutrient recommendations by explaining observed variation in recommended intakes of folate, vitamin B12, Fe and Zn for adults and elderly people. DESIGN We explored differences in recommended intakes of folate, vitamin B12, Fe and Zn for adults between nine reports on micronutrient recommendations. Approaches used...

Exoskeletons potentially reduce physical strain on workers. However, studies investigating the long-term effects of exoskeletons in workplace are rare, not least because demonstrating impacts faces several challenges, including collection reliable biomechanical data with exoskeleton. By examining potential impact using an exoskeleton inter-day measurements, we can provide valuable insights into...

The tutorial addresses the problems connected with requirements modelling in a UMLbased development process. UML supports requirements modelling by means of use cases. This practice suffers from several limitations, especially as use cases are quite informal descriptions –thus allowing ambiguities and misinterpretation of requirements– and they are not object-oriented –thus making traceability ...
