Most of the previous diagnostics research for vapor compression equipment has been performed for packaged air conditioners and chillers. This paper describes application of a decoupling-based diagnostic technique that was originally developed for air conditioners to equipment used in walk-in coolers and freezers. Testing was performed on a small, restaurant-style walk-in cooler and a small walk...

A current debate exists as to whether locomotion on foot is guided by optic flow (the apparent motion of the world when the subject is moving) [1–4] or perceived direction [5]. Rushton et al. [5] have shown that the path taken by a participant wearing prism spectacles is described reasonably by a model predicting trajectory from visual direction. We repeated Rushton et al.’s [5] experiment but ...

This document describes service classes configured with Diffserv and recommends how they can be used and how to construct them using Differentiated Services Code Points (DSCPs), traffic conditioners, Per-Hop Behaviors (PHBs), and Active Queue Management (AQM) mechanisms. There is no intrinsic requirement that particular DSCPs, traffic conditioners, PHBs, and AQM be used for a certain service cl...

A demonstration was conducted to examine the stored forage yield and stored forage quality of two different hay forage management systems. The forage management systems were a hay harvest only system or a complimentary hayround bale silage harvest system. The hay system harvested bermudagrass forage as hay during the summer when weather conditions allowed, the complimentary system harvested ber...

OBJECTIVE This study evaluated the effect of three metal conditioners on the shear bond strength (SBS) of a prosthetic composite material to cpTi grade I having three surface treatments. MATERIAL AND METHODS One hundred sixty eight rivet-shaped specimens (8.0x2.0 mm) were cast and subjected to polishing (P) or sandblasting with either 50 mm (50SB) or 250 mm (250SB) Al2O3. The metal conditione...

The aim of this study was to evaluate the effect of sealer application and thermal cycling on the bond strength between tissue conditioners and acrylic resin, and to observe the type of bond failure. Two hundred eighty-eight specimens (10x16x3 mm) were made of an acrylic resin (Lucitone 500, Dentsply) using a metal muffle. Specimens were divided into four groups according to the tissue conditio...
