Control chart techniques have been widely used in industries to monitor a process in quality improvement. Whenever we deal with variables data, we usually employ a combination of X-bar chart and R chart (or S chart) to monitor both the center and the spread of the process. In this paper, we propose a simple alternative, that is, we design a single chart to monitor both the center and the spread...

abstract. in recent years several studies have shown that  control charts with adaptive schemes or double sampling plans detect both small and moderate shifts in the process mean more quickly than the traditional shewhart  chart. in the classical double sampling  chart, the difference between two points were placed in the central region of first stage was not considered. in this study, a new co...

BACKGROUND Typically, symmetrical markings are made to lower the inframammary fold (IMF) according to the surgeon's judgment. Because inferomedial fascial attachments of the IMF may at times compromise the proper seating of the implant in this area, causing excessive superior projection, asymmetrical lowering of the IMF is performed to allow for increased lowering of the inferomedial aspect of ...

Changing seating posture can extend the amount of time a person can safely remain seated without damaging tissue or becoming fatigued. The Excelsior is an electrically powered wheelchair that utilizes sit-to-stand (STS) and sit-to-recline (STR) motions to aid in pressure relief. The motion of the wheelchair seating system must closely follow anatomical paths or ulcers may develop from the resul...

CONTEXT The identification and evaluation of activities capable of dislodging calyceal renal calculi require a patient surrogate or validated functional pyelocalyceal renal model. OBJECTIVE To evaluate roller coaster facilitation of calyceal renal calculi passage using a functional pyelocalyceal renal model. METHODS A previously described adult ureteroscopy and renoscopy simulator (Ideal An...

PURPOSE The aim of this study is to describe the clinical features of powered wheelchair users with severely disabling multiple sclerosis (MS) and explore the problematic clinical features influencing prescription. METHOD Retrospective review of electronic and case note records of recipients of electric-powered indoor/outdoor powered wheelchairs (EPIOCs) attending a specialist wheelchair serv...
