The MED-PC experimental apparatus programming system

Abstract: MED-PC is a software system that implements the MEDSTATE NOTATION dialect of state notation on IBM PC and compatible computers equipped with MED Associates interfacing. It provides a programming environment in which users can write short programs in a specialized language to control and record the events of operant and classical conditioning experiments. As many as eight experimental stations, each with up to 8 inputs and 32 outputs, running the same or different experimental procedures, may be active simultaneously. The system provides a standard set of run-time features, including mechanisms for displaying real-time data, simulation of responses, manipulation of array and variable contents, and writing of disk files. The system is based upon polling techniques, and is implemented as a translator that generates Pascal units, which are then linked to previously compiled Pascal routines.

Simulation studies of islanded behavior of grid-connected photovoltaic systems

Abstract: Simplified computer models are presented for predicting the run-on time of self-commutated inverters operating in a utility interactive mode. The inverter receives DC power from a photovoltaic (PV) array and delivers AC power to a local load or the utility lines. The models represent the dynamics of a phase-locked loop control circuit that is designed to destabilize the inverter operation and shut down the power-conditioning subsystem when a phase discrepancy between the line and some reference signal is detected. The sustained isolated operation (or islanding) of the PV system poses a possible safety concern to utility personnel and potential damage to utility-connected equipment. Two computer models, the TESLACO model and the APCC model, were implemented on an IBM PC using Pascal. They provide results compatible with experimental evidence and more elaborate computer modeling techniques. >

An inexpensive interface for the IBM PC/XT and compatibles

Abstract: An inexpensive interface designed for IBM PCIXTs or compatibles, potentially useful for con­ trolling behavioral/neural experiments, is presented. Descriptions of basic machine language rou­ tines for the control of input/output functions, timing, and data acquisition by the interface are provided. Also, a briefdescription of available Forth routines for controlling the delivery ofstimuli and the acquisition of behavioral/neural data during classical conditioning experiments is presented. In this article, we describe an interface for the IBM PC/XT that has been used for several years to control and collect data in classical conditioning experiments (e.g., Lavond, Steinmetz, Yokaitis, & Thompson, 1987). The system can be used on-line, providing immediate display of responses, or off-line. Although IBM no longer makes the PC/XT computer, there is still a large market for their clones at reasonable prices. Given the availability and power of these models, the interface and software de­ scribed in this article may serve as an attractive alterna­ tive to the KIM-l system developed by Solomon and col­ leagues (Solomon & Babcock, 1979; Solomon, Weisz, Clark, Hall, & Babcock, 1983) and to the system devel­ oped by Gormezano and colleagues for classical condi­ tioning with the Apple II series of computers (Scandrett & Gormezano, 1980). The retail cost of parts for this interface is less than $100 (including chips, board, wire, sockets, and cables), and it takes about 8-10 h to wire wrap by hand. In designing and programming this inter­ face, we found books by Eggebrecht (1983), National Semiconductor (1981), Rector and Alexy (1980), Royer (1987), and Willen and Krantz (1984) to be very useful.

A simulation support system for solving large physiological models on microcomputers

Abstract: Although physiological modeling and computer simulation have become useful research tools to test new scientific theories and to design and analyze laboratory experiments, developing a new model can be a tedious process because the investigator must often write very complex and specific routines for data input and output. To facilitate the design of new models (as well as the use of existing models), we have developed MODSIM, a FORTRAN -based simulation support system for the IBM PC computer than can accommodate very large dynamic models having up to several thousand equations. It provides the investigator with utilities for continuous on-line graphical and/or tubular output, as well as facilities for dynamic interaction with the model. The user must only supply a model as a list of mathematical equations written in FORTRAN , along with the initial values of the model variables and parameters. The model is precompiled, compiled, and then linked to the MODSIM utilities. Without further programming, the user can then solve the model, select variables for graphical output, and stop the model at any time to analyze the data or to change a parameter before resuming the simulation. This simulation system makes it very easy to develop new models that actively interact with the experimental research of the investigator.

The XDOS binary code conversion system

Abstract: The XDOS binary code conversion system takes the binary images of programs that were written to run on the IBM PC and converts them into programs that will run on a number of different computers that use the Unix operating system. The author discusses the use of automatic and human-aided conversion techniques, the techniques used to analyze programs, optimizations that are performed during conversion, run-time strategies, and the relative performance of converted code. It is shown that the XDOS binary code conversion system has proved to be an effective solution to the problem of running PC programs on Unix-based computers. It is able to produce converted applications that are well integrated into the Unix environment and that provide excellent performance in a multiuser environment. >

PC-CAPP-a computer-assisted process planning system for prismatic components

The software incorporates various modules for component feature representation; automatic machine, toolings and process parameter selection; set-up planning; production time calculation and finally the report generation. The user-friendly software package has been developed on an IBM PC/XT compatible system. It provides a quick and efficient method for generating consistent process plans.

Synchronizing stimulus displays with millisecond timer software for the IBM PC

Abstract: A C language technique for synchronizing millisecond timer software to the appearance of the stimulus on the IBM PC’s video monitor is described. Tachistoscopic programs that use the technique can correct the mean 8.3-msec bias normally found in reported response latencies and reduce the associated error variance.

ANTHEPROT: IBM PC and Apple Macintosh versions.

Abstract: The translation has been realized on an IBM-PC-compatible computer. The program has also been checked on the IBM PS/2 series. Options are given for graphic cards (EGA, CGA, VGA, Hercules). The input of sequences is made via an editor which allows the sequences to be corrected. All the graphics can be displayed on the screen together with a movable cursor on the curve. The coordinates of this cursor are displayed at the same time above the profile as well as the given amino acid position (see Figure 1). This improvement allows the user to identify both the amino acid (with its position) and its corresponding value. Facilities have also been included to permit the plot of proteins of any length by means of variable scaling factors. A new option predicts the amphiphilicity of a-helices and 0-sheets (Eisenberg et al., 1982). The possibility of displaying the helical wheel (orthogonal projection of a-helices) is also offered. The secondary structure prediction methods have been translated with the possibility of predicting a set or subset of proteins and of saving the predicted states into a single file. For the HOMOL and DIRINFO programs, the possibility of scanning the a-helix, /3-sheet, /3-turn and coil potentials is given by a graphic display. The GOR method has been implemented as described by Gibrat et al. (1987) using the new set of parameters.

Pcvista: a library of astronomical image-processing programs for the ibm pc

Abstract: We discuss a collection of programs to display and analyze astronomical images on IBM-PC and compatible computers. These programs, based on the VISTA program at Lick Observatory and on DAOPHOT at Dominion Astrophysical Observatory, have facilities to display data in FITS format on a variety of monitors, to perform elementary arithmetic operations on images, to do simple photometry, and to extract one-dimensional information. The merits of PC versus minicomputer-based image processing are discussed.

A 16-Mbit/s adapter chip for the IBM token-ring local area network

Abstract: The authors describe a 9.02*9.02-mm chip built in 1- mu m CMOS with two levels of metal and an additional mask level for fabricating capacitors. It contains both analog and digital circuits and has provisions for self-test. The function includes the transmitter, receiver, protocol handler, an microprocessor, as well as interfaces for RAM/ROM storage, IBM PC bus, IBM PS/2 bus, IBM 3174 bus, and Motorola 68000 bus. The physical design terrains are formed by 24K circuits of standard cell gates, a 10K-circuit equivalent hand-honed custom microprocessor, and an analog macro. The chip operates from a single 5-V supply, and the power consumption is 0.8 W nominal at 16 Mb/s. The chip can also be operated at 4 Mb/s. >

Tradeoff decisions made for a P1149.1 controller design (ATE)

Abstract: The author documents tradeoffs involved in designing an IEEE P1149.1/Joint Test Action Group (JTAG) scan bus master (SBM) that can operate at 25 MHz and interfaces a parallel host processor data bus to the serial P1149.1 test bus. By controlling the bits and all P1149.1 protocol for the host through an external device, the speed of running tests and scanning data is increased. Speed and throughput improve as more functions are implemented in controller hardware and fewer in host processor software. However, some advanced features require additional pins. Since the desired goals were a smaller part to fit more easily in a UUT (unit under test) and lower device cost, not all of the high-end functions were attained. The goals for the SBM were to maximize capability within the limit of device size, to be able to work in an IBM PC test station, and to be upwardly compatible with future products. Tradeoffs made for host synchronization, scan throughput, and more flexible commands reduce processor software overheard and improve scan and test rates. Evidence so far indicates that the SBM has met these goals. Prototype parts tested in a PC-based test system functioned as expected. >

cLOGISTIC: A Conditional Logistic Regression Program for the IBM PC

Abstract: cLOGISTIC performs conditional logistic regression analysis of data arising from stratum-matched case-control studies. cLOGISTIC can process as many as 20 explanatory variables and 500 strata with as many as 10 cases plus controls per stratum, provided the product of the numbers of subjects and explanatory variables is no greater than 6,000. The explanatory variables may include interactions created on the fly. Output includes confidence limits for the individual parameters. Likelihood ratio statistics for the significance of each variable are available. cLOGISTIC, written in Microsoft FORTRAN (version 4.10), runs on the IBM PC and compatibles using DOS 2.0 or later versions. The source code (not provided) contains 1,561 lines, 346 of which are comments. cLOGISTIC operates on MYSTAT system files (Wilkinson 1987) but may be run independently of MYSTAT by using WUBAWUBA (Dallal 1987), which converts ASCII files of numerical data to MYSTAT system files. A disk containing executables and user guides for cLOGISTIC and WUBA-WUBA may be obtained by sending a formatted 51/4inch floppy disk in a self-addressed mailer or by sending a $5 check to me.

A four-channel IBM PC/AT compatible biphasic pulse generator for nerve stimulation

Abstract: An IBM PC/AT compatible four-channel biphasic pulse generator developed to assist in functional electrical stimulation (FES) related research is discussed. Each channel uses a bipolar 12-bit digital-to-analog converter to generate biphasic voltage pulses between +/-5 VDC and three 16-bit timers to control first, second, and interphase durations. Two vectored interrupt generators are available for precise pulse timing control. Potential uses of this device include FES research, the characterization of the recruitment properties of percutaneous electrodes in multichannel stimulation systems, and use as a subassembly in commercial medical devices requiring electrical simulation in an IBM PC/AT platform. >

A New Approach to Laboratory Motor Control: MMCS the Modular Motor Control System

Abstract: : Many projects within the GRASP laboratory involve motion control via electric servo motors, for example robots, hands, camera mounts and tables. To date each project has been based on a unique hardware/software approach. This document discusses the development of a new modular, and host independent, motor control system, MMCS, for laboratory use. The background to the project and the development of the concept is traced. An important hardware component developed is a 2 axis control motor control board that can be plugged into an IBM PC bus or connected via an adaptor to a high performance workstation computer. To eliminate the need for detailed understanding of the hardware components, an abstract controller model is proposed. Software implementing this model has been developed in a device driver for the Unix operating system. However for those who need for wish to program at the hardware level, the manual describes in detail the various custom hardware components of the system.

Xinu/WU: an improved PC-Xinu clone?

Abstract: In teaching an undergraduate course in Operating Systems, it is instructive if the students have an actual operating system they can study and modify. Care should be taken, however, in selecting a system that the students can realistically be expected to understand. Xinu/WU retains the advantages of its parent PC-Xinu [Fossum 1987]; a small yet relatively complete operating system for the IBM PC, supplied with full source code and able to run within its development environment. Xinu/WU incorporates three particular enhancements: an improved implementation, integration into Borland International's Turbo C™ run-time environment, and more effective use of the windowing system. The conclusion is that Xinu/WU increases the possibility of using such a system in an undergraduate Operating Systems course. Two ways in which it can be utilized are presented.
