With simulation clinics, dental schools have improved their preclinical laboratories to provide a more realistic clinical teaching environment. However, there is very little data to support the assumption that these facilities actually improve student performance of technical skills. This study compared the scores of two fixed preparations for full cast crowns by third-year dental students. One...

A cloud does not have infinite computational and storage resources in its infrastructure. If it saturates, it will not be able to satisfy new requests for service allocations sent by its customers. Clouds should interrelate through networking protocols in order to provide scalability, efficiency and flexibility by using the services and the computational and storage resources of the infrastruct...

In this paper, the control methods of brake test bench are studied. According to as much as possible consistent principle of braking process between on the test bench and road test vehicle, by controlling motor to work under certain regular current, compensate lack energy owing to the shortage of electricity, establish control model of equivalent inertia and vehicle load. At the same time, we m...

SOC’s are getting larger all the time and so is the challenge to verify these designs in a short period of time. This paper presents a transaction level-based methodology in the VMM to standardize development of various pieces of a verification environment and the communication between them. This methodology promotes reuse and helps integrate modules from various sources to interact together se...

The analysis of benchmark experiments consists in a large part of exploratory methods, especially visualizations. In Eugster et al. [2008] we presented a comprehensive toolbox including the bench plot. This plot visualizes the behavior of the algorithms on the individual drawn learning and test samples according to specific performance measures. In this paper we show an interactive version of t...

Theoretical stimulation waveforms were implemented for bench testing on a research implantable pulse generator system for testing of safety and efficacy. The waveforms each consisted of a conditioning “pre-pulse” phase (e.g., a depolarizing pre-pulse) a stimulation phase, and a passive recharge phase. They were bench tested in a completely electronic system and in a saline model. The waveforms ...

OBJECTIVES: The objectives of this study were to (1) summarize published literature on biological perchlorate/nitrate destruction; (2) perform bench-scale tests to characterize biodegradation parameters (i.e., salinity, pH, temperature, nutrients, electron donor, etc.), improve perchlorate/nitrate destruction rates, and evaluate mechanisms to generate and retain biomass; and (3) validate bench-...

This paper presents the results obtained with a specific test mask designed at Motorola for the study of the electromagnetic parasitic emissions in integrated circuits (IC). First, origins of parasitic emissions are presented for CMOS circuits, and electromagnetic compatibility (EMC) measurements of IC emissions are detailed: a radiated measurement method with respect to the IEC61967-2 standard...
