This study was to evaluate the acid-buffering capacity and antibacterial properties of orthodontic adhesives containing bioactive glasses (BAGs) (45S5, 45S5F, S53P4), Hydroxyapatite, beta-tricalcium phosphate, Canasite. Fillers comprising 15 wt% glasses, HAp, β-TCP, Canasite incorporated with 55 silanated glass were added a mixture UDMA/TEGDMA. Acid-buffering tested by exposing disc-shaped samp...

Virtual output queueing is commonly deployed as a buffering technique in high-performance input-queued switch architectures. This paper presents analysis for discrete-time virtual output queued switches with incoming traffic governed by a uniformly distributed Markov modulated ON/OFF process, and geometrically distributed service times. We utilize the k-step first-passage time probability matri...

My thesis is largely focused on the parallelisation of UCT (and other Best-First Search techniques) and the ramifications of doing so. I have identified issues with chunking in UCT, created by some forms of parallelisation, and developed a solution to this involving buffering of simulations that appear “out of order” and reevaluation of propagation data. I have developed a technique for scalabl...

In this work, we study the different buffering techniques used in the literature to solve the contention problem in A TM switching architectures. The objective of our study is to determine the buffer requirements needed to achieve a given Quality of Service (e.g., a given cell loss probability). Based on this study, we propose a Combined Central and Output Queuing (CCOQ) technique to be used in...

The purpose of this study was to identify ways in which social support is related to the caregiving stress and well-being experienced by adult daughter caregivers. The study focused on a specific source of support, caregivers' husbands, and included reports from 126 caregivers and their husbands. Main and buffering effects of four types of support (emotional and instrumental support provided to...

Neutrophil polarity relies on local, mutual inhibition to segregate incompatible signaling circuits to the leading and trailing edges. Mutual inhibition alone should lead to cells having strong fronts and weak backs or vice versa. However, analysis of cell-to-cell variation in human neutrophils revealed that back polarity remains consistent despite changes in front strength. How is this bufferi...

Interactive virtual environments used in conjunction with haptic displays are often staticviewpoint scenes that contain a mixture of static and dynamic virtual objects. The immersive realism of these environments is often limited by the graphical rendering system, typically OpenGL or Direct3D. In order to present more realistic scenes for haptic interaction without requiring additional modeling...

Circuit-switched Banyan interconnection networks can be built from simple switching elements that do not have logical processing or buffering capabilities. This paper describes a distributed technique for dynamic control of such a network, so that circuits can be established in response to the changing needs of a parallel application. Control information is interleaved with data, thus avoiding ...
