We investigate the characteristics of constant-amplitude input shapers for robust time-optimal maneuvers of exi-ble structures. Trends in the timing of the shaper impulses are shown as a function of the system damping constant and move distance. The insensitivity to modeling errors, time-optimality, amount of vibration caused during maneuvers, and high frequency excitation of these shapers are ...

This paper addresses the advance scheduling of elective surgeries in an operating theater composed rooms and a downstream surgical intensive care unit (SICU). The arrivals new patients each week, duration surgery, length-of-stay patient SICU are subject to uncertainty. At end surgery planner determines blocks open next week assigns subset on waiting list blocks. objective is minimize patient-re...

BACKGROUND AND OBJECTIVES There is little strong evidence relating to the impact of single-room accommodation on healthcare quality and safety. We explore the impact of all single rooms on staff and patient experience; safety outcomes; and costs. METHODS Mixed methods pre/post 'move' comparison within four nested case study wards in a single acute hospital with 100% single rooms; quasi-experi...

the study evaluated the physical qualities and satisfaction in students’ housing in selectedstudents’ housing for the university of ibadan. through survey method, eight hostels were purposively selected tocapture variation in gender, level of study and hostel design. the sampling frame showed that 5605 students at ui werefound in 2,147 rooms. one out of every 10 (10%) of the rooms were selected...

BACKGROUND Patients in intensive care units (ICUs) often acquire infections, which impose a heavy human and financial burden. The use of private rooms may reduce the acquisition of certain pathogens, but the limited evidence on this topic is inconsistent. METHODS We compared the rates of acquisition of infectious organisms in an ICU before and after a change from multibed to single rooms. As ...
