culation by the aid of a reliable formula, then, is an important aspect of applied acoustics. A reverberation time formula enables one to calculate the reverberation time once the volume, surface area and average absorption coefficient of the surface of the room are known; or if the reverberation time is measured it enables one to calculate the average coefficient of absorption of the surface t...

In this paper, we present a detailed analysis of the face recognition problem in smart room environment. We first examine the wellknown face recognition algorithms in order to observe how they perform on the images collected under such environments. Afterwards, we investigate two aspects of doing face recognition in a smart room. These are: utilizing the images captured by multiple fixed camera...

If you ask patients what they dislike about seeing doctors, there is a fair chance they will mention having to sit in waiting rooms for ages. Doctors tend to get defensive when they hear this and are likely to offer reasons why it happens. These usually include the following. ‘There are never enough doctors, so we are always working against the clock.’ ‘Consultations are unpredictable and may g...

The physical measures by which acousticians evaluate the performance of rooms have evolved in large performance spaces—concert halls. They rely on assumptions that become progressively less valid as spaces get smaller and more acoustically absorptive. In listening rooms the loudspeakers and the rooms interact differently below and above a transition region around 300 Hz, similar to the Schroede...

patient safety and psychological benefit. Others say the evidence in support of private rooms in hospitals is inconclusive, while the more cynical suggest the ration of single-patient rooms to multi-patient rooms in hospitals is carefully designed to generate revenues. But the growing incidence of hospital-acquired infections has the nation’s nonprofit standard setting association calling for p...

AIMS AND OBJECTIVES To explore whether and how spatial aspects of children's hospital wards (single and shared rooms) impact upon family-centred care. BACKGROUND Family-centred care has been widely adopted in paediatric hospitals internationally. Recent hospital building programmes in many countries have prioritised the provision of single rooms over shared rooms. Limited attention has, howev...

A limited number of rooms are equipped with electronic equipment that allows ETS to remotely monitor AV operations or class capture problems so we can provide instant service without entering the classroom. These 23 rooms are clearly marked with signs alerting users to consider them "public" spaces and to refrain from discussing private or confidential matters. ETS limits the number of persons ...
