This paper describes recent research activities and results in the area of photonic switching carried out within the Virtual Department on Switching (VDS) of the European e-Photon/ ONe Network of Excellence. Contributions from outstanding European research groups in this field are collected to offer a platform for future research in optical switching. The paper contains the main topics related ...
BACKGROUND The advantages of platform switching using narrower abutments remain controversial. Many researchers suggest that platform switching can yield enhanced clinical results, while others remain skeptical. We hypothesize that the effectiveness of platform switching might be associated with the degree of reduction in size of the abutment. PURPOSE To radiographically and clinically examin...
OBJECTIVE Long-term success of dental implants depends on healthy peri-implant soft tissues and adequate bone levels. This prospective study aims to assess bone level changes around implants with internal conical connection and platform-switching abutments in the posterior mandible. MATERIAL AND METHODS Adult patients missing at least two teeth in the posterior mandible and with a natural too...
PURPOSE The aim of this pilot study was to determine what effect thin mucosal tissues can have on crestal bone stability around implants with platform switching. MATERIALS AND METHODS Twelve 2-piece implants, consisting of 6 implants with horizontally matching implant-abutment connection (control) and 6 implants with platform switching (test) were placed in 4 patients. The mean age of the pat...
The level of bone crest surrounding the implant is of utmost significance to determine osseointegrated implant success, as preservation of marginal bone height is highly important for long-term dental implant survival. Various approaches have been described in the literature to prevent the crestal bone loss, including platform switching, non-submerged approach, scalloped implants, implant desig...
In this paper we propose an approach to improve the direct torque control (DTC) of an induction motor (IM). The proposed DTC is based on fuzzy logic technique switching table, is described compared with conventional direct torque control (DTC). To test the fuzzy control strategy a simulation platform using MATLAB/SIMULINK was built which includes induction motor d-q model, inverter model, fuzzy...
Handel-C is a convenient tool for high-level design for FPGAs. Platform FPGAs, with high-levels of integration are suitable as packet processing devices. An existing ATM packet-switching design has been augmented with a CAM, with a simplified control structure, by the addition of a back-pressure mechanism, and a new shared-memory buffering scheme. The paper gives details of the Handel-C impleme...
