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 inte...

In this paper the implementation of a contour tracking procedure is presented. If a rough contour of the desired structure is available on the first frame of a sequence, the contours on the subsequent frames are automatically outlined in real time. Furthermore, indices of clinical interest are calculated from the computed contour and they are graphically displayed in real time. The software run...

There is a growing demand to port existing PC-based software systems to mobile device platforms. Systems running on mobile devices share basic characteristics with their PC-based counterparts, but differ from them in details of user interfaces, application models, etc. Systems running on mobile devices must also perform well using less memory than PC-based systems. Mobile devices themselves are...

This paper introduces an auto-configuration system that is intended to enable people with very basic computer networking skills to set up a router network from opensource software and commodity PC hardware. Our system is composed of three subsystems: Operating System autoinstallation subsystem, IP address auto-assignment subsystem, and OSPF auto-configuration subsystem. We have implemented the ...

We present our contribution to the general-purpose-processor-(GPP)-based radio.We describe a baseband software-defined radio testbed for the physical layer of wireless LAN standards. All physical layer functions have been successfully mapped on a Pentium 4 processor that performs these functions in real time. The testbed consists of a transmitter PC with a DAC board and a receiver PC with an AD...

In this paper, we describe QRobot, a low level real-time PC-based system for controlling PUMA robot manipulators. Specifically, we illustrate how a standard PUMA controller can be retrofitted with interface boards that allow it to be connected to an industry standard PC. All computational units are removed from the existing PUMA controller, and the PC assumes the role of computing the control s...

OSPF (Open Shortest Path First) is a widely used intra-domain routing protocol in IP networks. Processing delays in OSPF implementations impact the time needed for both intra-domain and inter-domain routing to re-convergence after a topology change. The re-convergence capability of a router can be characterized by a performance index, referred to as switching time. We have built a test-bed and ...

This report represents the design and implementation of a skin temperature measurement system. The system aims to measure the skin temperature from a sensor and send it to the PC using a USB cable to display on screen. The data needs to be updated every second. The PIC18F4550 microcontroller has been used in this project to obtain data from the sensor and send it to the PC using USB 2.0 that ha...

The paper presents a new system for electrochemical researches based on PC and LabVIEW software package. An overview of well known electrochemical methods, such as potential measurements, chronopotentiometry, chronoamperometry, cyclic voltammetry and EIS is given. Electrochemical impedance spectroscopy has been adapted for systems containing large capacitances. For signal generation and recordi...
