Prosthetic periodontal treatment with a fixed partial prosthesis has been carried tients affected by severe periodontitis in order to restore dentition to good health, function, and esthetics. The literature has proven that the biological capability of teeth with a reduced but healthy periodontium successfully supports a fixed partial prosthesis over time. In gren demonstrated that fixed bridge...

b fast and highly reliable method of inspecting minule solder joints of high-density rnouaed devices hns been dcveloperl. It uses two techniques to detect all types of defects, such as unsoldered leads. solder bridges. and mis-aligned leads. One applieszxternal Form to solder joints with an air jet. which vibrates w shifts unsoldered leads. The vibration and shift is detected as a change in the...

Automatic detection of geographical objects such as roads, buildings and bridges from remote sensing imagery is a very meaningful but difficult work. Bridges over water is a typical geographical object and its automatic detection is of great significance for many applications. Finding Region Of Interest (ROI) having water areas alone is the most crucial task in bridge detection. This can be don...

Automatic balancing dc and ac resistance ratio bridges are the primary measurement devices used by National Measurement Institutes for the calibration of standard platinum resistance thermometers (SPRTs) on the International Temperature Scale of 1990 (ITS-90). Performance assessment of these resistance ratio bridges is critical to the determination of both the uncertainties of the measurements ...

In this paper w e discuss three little known letters on the Konigsberg bridges problem. These letters indicate more clearly Euler’s attitude to the problem and to his solution of it.

The riveted type of construction is characteristic of older railway bridges. As some of these bridges approach, or have even exceeded their theoretical fatigue life under increasing train loads, it is desirable to improve the procedures available for the assessment of fatigue-critical details. The aim of this paper is to present results through the use of the FE method, which address the manner...

The railroad network carries 40 % of the freight in the US. Railroad bridges are the most critical part of the network and they need to be properly maintained for safety of operations. Railroad managers inspect the bridges to assess their structural condition. Railroad managers are interested in measuring displacements under train crossing events to prioritize their bridge management and safety...
