OBJECTIVES To describe the incidence and extent of lying on the floor for a long time after being unable to get up from a fall among people aged over 90; to explore their use of call alarm systems in these circumstances. DESIGN 1 year follow-up of participants in a prospective cohort study of ageing, using fall calendars, phone calls, and visits. SETTING Participants' usual place of residen...

High-rise buildings are commonly built in densely populated countries or urban areas. A balanced floor construction cycle is critical for construction of the frame structures. The objectives in scheduling the floor cycle are to ensure smooth flows of resources and to optimise the use of formwork and other materials. The floor area is usually divided into zones to allow the labour force and form...

The aim of this guideline is to highlight the evidence for different surgical approaches, since the best chance of surgical ‘cure’ for stress incontinence is successful primary surgery. Primary surgery should only be considered after a period of conservative treatment from a specialist therapist has been offered and rejected, or has failed. There is evidence from a Cochrane review that pelvic-f...

Abstract Because the traditional analysis methods cannot directly describe comfort behavior of high performance floor through dimensions time and space, this paper presents a new method to derive Dirac delta functions governing differential equations assess its behavior. On basis this, an improved single-jump excitation model is proposed for analysis. In addition, analyzes distribution characte...

In this paper, we investigate the fuzzy logic based system characteristics of MX/G/1 retrial queuing system with Bernoulli vacation schedule. The service time and vacation time are assumed to be generally distributed. It is found in many practical situations that the queuing models with fuzzy parameters are much more realistic than the classical crisp parameters based queuing models. We have...
