Pc Based Instrumentation, Current Efforts and Future Technology
نویسنده
چکیده
Instrumentation based on the PC architecture has been fielded at many accelerator sites. The wide variety, high performance, and reasonable cost of both commercial hardware and software make this platform an attractive choice for instrumentation. Current efforts on the SNS accelerator include beam position monitors, wire scanners, and beam current monitors. The design issues related to PCI interfacing and mixed signal isolation in the SNS diagnostics are discussed. The detail of the interface between custom hardware and commercial software is also presented. Design issues regarding synchronous acquisition and processing of data in non real time systems are addressed. Current and future trends in PC hardware peripheral interconnects, including USB2, 1394, and PCI express are expanding the options available to instrument designers. The relative strengths of these interconnects for instrumentation and the state of commercial software support is presented.

Background: Recently, patient-specific instrumentation (PSI) systems have been developed in order to increase theaccuracy of component positioning during total knee arthroplasty (TKA); however, the findings of previous studies arecontroversial in this regard. In the current randomized clinical study, the outcomes of computer tomography (CT)-basedPS (patient specific)-guided TK...
متن کاملDesign and Practical Implementation of a New Markov Model Predictive Controller for Variable Communication Packet Loss in Network Control Systems
The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...
