background: since most clinical treatments of persian children’s language impairments are based on either the therapist, clinicians’ experiences (mostly), or english language norms (sometimes), comparing two minor indices of speech quality, namely “mean length of utterance” (mlu) and “mean length of five phrasal utterances” (mlfpu) between different age groups of children, would be unequivocall...

university course timetabling is a complex optimizationproblem. there are many components like departments, faculties, rooms,and students making the problem huge and difficult to solve. eachcomponent enforces a set of normally conflicting constraints on thesolution space. the problem will be solved if courses are scheduled indifferent rooms and within some specific time slots such that a set of...

In this paper we discuss the complexity and approximability of the minimum corridor connection problem where, given a rectilinear decomposition of a rectilinear polygon into “rooms”, one has to find the minimum length tree along the edges of the decomposition such that every room is incident to a vertex of the tree. We show that the problem is strongly NP-hard and give an subexponential time ex...

results higher levels of stress were due to the fear of being infected by hiv and hepatitis patients with mean of 3.2 and 58%; and lack of weekends with mean of 3 and 44%. the lowest levels of stress were related to inadequate skills with mean of 2.18 and 32%, and environment light with mean of 2.14 and 34.7%. stress was significantly related to job status, conflict of doctors and nurses as wel...

Increasing emphasis on patient privacy and satisfaction has seen more 100% single-room hospitals opened across the UK. Few studies have addressed the impact of these new hospital designs (single rooms) on clinical outcomes specifically for acutely unwell frail patients with dementia. The objective of this study was to profile and compare the clinical outcomes of acutely unwell patients with dem...

While advances in CAD modeling techniques led to an ever increasing number of available architectural 3D models, reusability of these models as templates or as inspiration sources is still very limited. One reason for this is that there exist basically no shape retrieval methods specialized in the architectural domain. In this work, we therefore present a method to efficiently characterize 3D a...
