FiberDistributed DataInterface (FDDI) is a100megabits per second ber optic local area network (LAN) standardbeing developed by the AmericanNational Standard Institute (ANSI). We analyze the impact of various designdecisions onthe error detectioncapabilityof the protocol. Inparticular, we quantifyframe error rate, tokenloss rate, andundetectederror rate. Several characteristics of the 32-bit fra...

The main purpose of the paper is to present the results of probabilistic homogenization of the fiber-reinforced composites with stochastic interface defects. The mathematical model of the composite is based on the interphase containing all interface defects which are averaged within this region. Next, the effective modules method is applied to compute the effective thermoelastic characteristics...

Background: Focusing with a 4π parabolic mirror allows for concentrating light from nearly the complete solid angle, whereas focusing with a single microscope objective limits the angle cone used for focusing to half solid angle at maximum. Increasing the solid angle by using deep parabolic mirrors comes at the cost of adding more complexity to the mirror’s fabrication process and might introdu...

This article reports on an empirical investigation of user perceptions of the importance of several characteristics of interface agents. Interface agents are software entities that are incorporated into various computer applications, including electronic mail systems. As evidenced by the growing body of empirical studies and the increasing number of interface agent-based applications on the sof...

Pressure ulcer incidence rates have remained constant despite advances in support surface technology. Interface shear stress is recognized as a risk factor for pressure ulcer development and is the focus of many shear reduction technologies incorporated into wheelchair cushions; however, shear reduction has not been quantified in the literature. We evaluated 21 commercial wheelchair seat cushio...

In this letter, we present a sapphire direct bonding method using plasma surface activation, hydrophilic pre-bonding, and high temperature annealing. Through the combination of sapphire inductively coupled plasma etching and the direct bonding process, a vacuum-sealed cavity employable for high temperature applications is achieved. Cross-sectional scanning electron microscopy (SEM) research of ...
