Micro Experimental Laboratory: An integrated system for IBM PC compatibles

Abstract: Micro Experimental Laboratory (MEL) is a third-generation integrated software system for experimental research. The researcher fills in forms, and MEL writes the experimental program, runs the experiments, and analyzes the data. MEL includes a form-based user interface, automatic programming, computer tutorials, a compiler, a real-time data acquisition system, database management, statistical analysis, and subject scheduling. It can perform most reaction time, questionnaire, and text comprehension experiments with little or no programming. It includes a Pascal-like programming language and can call routines written in standard languages. MEL operates on IBM PC compatible computers and supports most display controllers. MEL maintains millisecond timing with high-speed text and graphics presentation. MEL provides a systematic approach to dealing with nine concerns in running an experimental laboratory.

A pareto race

Abstract: A dynamic and visual “free-search” type of interactive procedure for multiple-objective linear programming is presented. The method enables a decision maker to freely search any part of the efficient frontier by controlling the speed and direction of motion. The objective function values are represented in numeric form and as bar graphs on a display. The method is implemented on an IBM PC/1 microcomputer and is illustrated using a multiple-objective linear-programming model for managing disposal of sewage sludge in the New York Bight. Some other applications are also briefly discussed.

More on millisecond timing and tachistoscope applications for the IBM PC

Abstract: This paper describes a method of establishing time intervals at a precision of better than 1 msec, using QuickBASIC 4.0, for running real time experiments on an IBM PC without an 8087 coprocessor. This method is far superior to the TIMER function provided by BASIC, which has a precision of only 110 msec. Also described is an assembly language subroutine that corrects a problem in QuickBASIC 3.0 and QuickBASIC 4.0 to allow proper switching between screens in the CGA text mode for use of the PC as a tachistoscope. A tachistoscope program listing shows how to use the screen subroutine and how to establish intertriai intervals and record reaction times using the timing subroutines.

Screen control and timing routines for the IBM microcomputer family using a high-level language

Abstract: Procedures are described for the IBM PC/AT and compatibles that measure an event’s duration with millisecond accuracy and that synchronize stimulus presentation with the vertical-retrace signal. The software is written in Turbo Pascal (Versions 2.0, 3.0, and 4.0; Borland International, Inc., 1984, 1985, 1987). Difficulties reflecting differences among video controller cards are also presented.

CSU, a highly automatic and selective program for the calculation and presentation of geometrical parameters and their e.s.d.`s

Abstract: A Fortran CRYSTAL STRUCTURE UTILITY (CSU) batch program for the analysis of X-ray crystal structures is described. Both mainframe and IBM PC/XT compatible computer versions are available. CSU provides, through a free-format-free-sequence input, automatic hydrogen modelling and search of chemical connectivity relationships, taking into consideration not only crystallographic symmetry, but also internal molecular symmetry. The program prints clear ready-for-publication tables free of redundant data. It enables data transfer from/to other programs such as XRAY76, SHELX76, $SYST$, ORTEP or MOLDRAW, but also it is possible to communicate with almost any other program used in small-molecule crystallography.

SPARTA: multiple signal processors for high-performance robotic control

Abstract: The authors describe the SPARTA (signal processor architecture for real-time applications) system, which is a hybrid computer development system including: (1) a program development environment on an IBM VM/CMS mainframe computer: (2) user interface and runtime support on an IBM PC; and (3) real-time computation and input/output using multiple IBM Hermes signal processors situated on the IBM PC bus. The program development environment includes the PLH high-level language for generating efficient real-time Hermes code. The runtime supports symbolic debugging, dynamic loading and linking, and synchronous switching of control algorithms during real-time program execution. The real-time environment includes a distributed operating system which supports foreground and background task execution and real-time data collection and display. The task switching overhead is 0.1 mu s, nonpreemptive, and 1.0-3.7 mu s when the context is changed by an interrupt (i.e. preemptive). >

A protein secondary structure prediction scheme for the IBM PC and compatibles

Abstract: A prediction scheme has been developed for the IBM PC and compatibles containing computer programs which make use of the protein secondary structure prediction algorithms of Nagano (1977a,b), Garnier et al. (1978), Burgess et al. (1974), Chou and Fasman (1974a,b), Lim (1974) and Dufton and Hider (1977). The results of the individual prediction methods are combined as described by Hamodrakas et al. (1982) by the program PLOTPROG to produce joint prediction histograms for a protein, for three types of secondary structure: alpha-helix, beta-sheet and beta-turns. The scheme requires uniform input for the prediction programs, produced by any word processor, spreadsheet, editor or database program and produces uniform output on a printer, a graphics screen or a file. The scheme is independent of any additional software and runs under DOS 2.0 or later releases.

C language functions for millisecond timing on the IBM PC

Abstract: This article describes four C language functions for programming the IBM PC and compatibles for timing with millisecond precision. The technique, which is based on a reprogramming of the PC’s real time clock, requires no additional hardware, no assembly language code, and no programming of machine or software interrupts. One function restores the PC’s time-of-day clock.

APT PC and APT II: Experiment development systems for the IBM PC and Apple II

Abstract: Systems for creating and running psychology experiments on an Apple II or IBM PC are described. Without programming, psychologists using the APT systems can construct and conduct an experiment, summarize the data, and revise the experiment. The systems are easily used by students but powerful enough to be used by psychologists in their research.

Computer Program for Analysing Interstratified Structures by Fourier Transform Methods

Abstract: A computer program for analysing two-component interstratified structures by two different Fourier transform methods is described The first method consists of the calculation of the X-ray diffraction intensity function, and in the second one (direct method) the distribution function of interlayer distances is calculated The programs have been written in compiled GWBASIC for an Olivetti M-24 microcomputer (MS-DOS operating system), and they may also be run on any IBM compatible personal computer As an example, this program is applied for the analysis of a chlorite-smectite interstratified mineral

Adaptation and implementation of the RAYGUN gamma-ray analysis code on the IBM PC

Abstract: The RAYGUN gamma-ray analysis code (a descendant of GAMANAL and GRPANL) has been converted from FORTRAN IV to RATFOR and ported to the IBM PC environment. The history of the code and some of the problems encountered during the conversion are discussed. The converted code was then used to analyze the IAEA G-1 Intercomparison Spectra as one measure of the codes performance. The results of the analyses showed that although the intrinsic peak finding and multiplet resolution capabilities of the code are a bit weak, the UPPER-LIMIT and LIBRARY-SEARCH options work quite well. When appropriate gamma-ray libraries are created, the overall performance of the code is quite satisfactory. The RAYGUN code runs on an IBM PC or clone with 256 Kbytes of RAM.

Versatile Raman spectrometer control with the IBM‐PC/XT

Abstract: The scan drive of a stepper motor, signal detection and data processing of the recorded Raman signals were controlled by a compatible IBM‐PC/XT which was connected to a Jarrell–Ash 25‐400 spectrometer. Excitation source fluctuations were eliminated by the simultaneous detection of a small portion of laser light. This reference and the Raman signals were transmitted to the 8‐bit parallel port of the IBM by multiplexing. The parallel port was modified to bidirectional data transfer so that control and signal processing required only one port.

The Topdown System and its use in Teaching - An Exploration of Structured, Knowledge-Based Design

Abstract: The Topdown System is a shell for use in developing simple (but we believe non-trivial) knowledge-based CAD systems. It provides a data structure, graphics capabilities, a sophisticated user interface, and programming tools for rapid construction of knowledge bases. Implementation is for Macintosh, Macintosh II, IBM PC/AT, PS12, and Sun workstations. The basic idea is that of top-down design - beginning with a very abstract representation, and elaborating that, in step-by-step fashion, into a complete and detailed representation. The basic operations are real-time parametric variation of designs (using the mouse and slide bar) and substitution of objects. Essentially, then, a knowledge-base in Topdown implements a kind of parametric shape grammar. The main applications of Topdown are in introductory teaching of CAD, and (since it provides a very quick and easy way for a user to develop detailed geometric models) to provide a uniform front-end for a variety of different applications. The shell, and some example knowledge-bases, are publicly available. This paper discusses the principles of the Topdown Shell, the implementation of knowledge bases within it, and a variety of practical design applications.

Using serial interfaces and the C language for real-time experiments

Abstract: The use of the serial interface of the IBM PC for timing and stimulus-response signaling is discussed. C language example programs, including two small software utility modules that expedite the programming of real-time experiments using a serial interface, are presented that are compilable with Borland’s Turbo C.

Personal computer based Fourier transform ion cyclotron resonance mass spectrometer

Abstract: An IBM PC AT compatible computer is used to host the interface of a Fourier transform ion cyclotron resonance mass spectrometer or FTMS. A common fast memory bank for both ion‐excitation waveform and data acquisition is reserved in the computer’s system memory space. All the digital electronics circuitry is assembled on an IBM PC AT extension board. Neither an external frequency synthesizer nor a waveform digitizer is needed. Ion‐excitation waveforms can be generated in either frequency‐sweeping or inverse‐Fourier transform modes. Both excitation and data acquisition can be carried out at eight megawords per second.
