Fall Prevention: Responder 5 Bed Connectors
<p>This paper explores falls, a sentinel event plaguing hospitals in the United States and internationally. Falls are a major contributor to negative patient outcomes and a source of financial strain for hospitals. One particular fall prevention intervention, Responder 5 bed alarms, was explored. A …

Modeling beam-decking connectors under failure conditions
… determining if the failure of the beam-decking connectors is such a dominant factor in the dome’s collapse that material and geometric nonlinearities can be neglected and useful results still be obtained. Since many different studies have been carried out on this dome model, this thesis will …

Behaviour of demountable shear connectors in composite structures
… to evaluate the feasibility of demountable shear connectors as an alternative to welded shear connectors in composite structures through push off tests and composite beam tests. Push off tests were conducted to examine the shear strength, stiffness and ductility of demountable shear connectors in …

Can connectors change team culture on fluid teams?
"Connectors—likable people with abnormally high motive, ability, and opportunity to develop relationships with lots of different people from different backgrounds (Autrey, Jackson, Klevsky, and Drasgow 2015a)—can help their teams become more effective by enhancing the team processes which …

Horizontal Shear Connectors for Precast Prestressed Bridge Decks
… different amount and different type of shear connectors. Two equations, for uncracked and cracked concrete interfaces, are proposed to be used in horizontal shear design when the precast panels are used. Predictive equations are compared with available methods for the horizontal shear strength …

Behavior and Strength of Welded Stud Shear Connectors
The behavior and strength of welded shear studs are subjects of ongoing study. In recent years, research has shown that the American Institute of Steel Construction (AISC) specification equations for shear stud strength are unconservative for studs placed in deck with ribs transverse to the steel …

Exploring the critical role of different routine connectors in post acquisition integration
… routines and puts forward the concept of routine connectors that connect one routine to another. In other words, this work shows how routines are held together. Case studies are constructed from 18 integrations to explain how business functions such as operations or marketing are integrated. While …

Electropermanent magnetic connectors and actuators : devices and their application in programmable matter
Programmable matter is a digital material having computation, sensing, and actuation capabilities as continuous properties active over its whole extent. To make programmable matter economical to fabricate, we want to use electromagnetic direct drive, rather than clockwork, to actuate the particles. …

Polyurethane Sealant to Mitigate Crack Effects in Glass-to-Metal Sealed Underwater Connectors
Glass insulated underwater connectors allow for deep sea exploration. However, the long term reliability of the insulation is reduced due to surface cracks formed during manufacturing. In this thesis, we propose and test a sealant to overcome limitations associated with internal cracks. The need …
