Acoustic emission (AE) testing was deployed on details of two large steel Interstate Highway bridges: one cantilever through-truss and one trapezoidal box girder bridge. Quantitative measurements of activity levels at known and suspected crack locations were made by monitoring AE under normal service loads (e.g., live traffic and wind). AE indications were used to direct application of radiogra...
General design rules and the scaling laws with wavelength for MEMS tunable optical filters are discussed for the first time. We describe how to determine dimensions and component materials from the system requirements such as tuning range, central wavelength, tuning voltage, tuning speed and resolution. The systematic design allows fair comparison among different topologies such as cantilever, ...
OBJECTIVE The objective of the present systematic review was to analyze the potential effect of incorporation of cantilever extensions on the survival rate of implant-supported fixed partial dental prostheses (FPDPs) and the incidence of technical and biological complications, as reported in longitudinal studies with at least 5 years of follow-up. METHODS A MEDLINE search was conducted up to ...
This article describes a 16-year-old male who was referred to the Prosthodontics Department due avulsion of right upper central incisor and fracture left incisor; avulsed tooth lost at accident site. The patient refused have his teeth prepared except for broken so single cantilever retainer denture bridge made with fiber post design ovate pontic. Radiographic examination performed evaluate apic...
According to contact type, RF MEMS switches are generally classified into two categories: Capacitive switches and Metal-to-Metal ones. The capacitive switches are capable to tolerate a higher frequency range and more power than M-to-M switches. This paper presents a cantilever shunt capacitive RF MEMS switch with characteristics such as low trigger voltage, high capacitive ratio, short switchin...
