“Omnidia”: software for taxonomy, calculation of diatom indices and inventories management

Abstract: Software for calculation of 6 diatom indices and diversity indices has been created for both Macintosh and IBM compatible computers. This software runs with the data base Omnis 5 under Windows 3.0. It includes three taxonomic files: families, genera and species, and an inventories file. Four types of data inputs are possible. It is always possible to operate simulations and to carry out investigations with simple or combined characters. All files and results of investigations can be listed in different ways. This data base is compatible with both word processing and spreadsheet systems.

A real-time face recognition system using custom VLSI hardware

Abstract: A real-time face recognition system has been implemented on an IBM compatible personal computer with a video camera, image digitizer, and custom VLSI image correlator chip. With a single frontal facial image under semicontrolled lighting conditions, the system performs (i) image preprocessing and template extraction, (ii) template correlation with a database of 173 images, and (iii) postprocessing of correlation results to identify the user. System performance issues including image preprocessing, face recognition algorithm, software development, and VLSI hardware implementation are addressed. In particular, the parallel, fully pipelined VLSI image correlator is able to perform 340 Mop/second and achieve a speed up of 20 over optimized assembly code on a 80486/66DX2. The complete system is able to identify a user from a database of 173 images of 34 persons in approximately two to three seconds. While the recognition performance of the system is difficult to quantify simply, the system achieves a very conservative 88% recognition rate using cross-validation on the moderately varied database.

A powerful, inexpensive experiment controller or IBM PC interface and experiment control language

Abstract: A very powerful, but inexpensive, advanced technology (16 MHz 80C188EB) experiment controller is described. It can be programmed in either a BASIC-like (ECBASIC) or an ALGOL-like (ECL) procedure specification language. It provides 1-msec resolution, optional transparent total data logging, and is designed to function as a remote peripheral processor in a network with virtually any computer acting as the network supervisor (e.g., IBM compatible or Macintosh). Each serial port on the host computer can support up to 10 simultaneous experiments. The various optional I/O modules provide for opto-isolated normally open or normally closed switch operation input, high current output, as well as D/A and A/D functions. Our I/O modules can also be plugged directly into an IBM PC parallel port by using a small adaptor board. In this way, the advantages of using ECBASIC or ECL to control experiments are available to researchers who wish to simply interface their host computer directly to the apparatus in order to minimize expense.

ANALNRA — charged particle nuclear reaction analysis software for the IBM PC

Abstract: Nuclear reaction analysis (NRA) is a powerful ion beam technique which can only be fully harnessed with suitable analysis software. ANALNRA is a NRA analysis package written for situations when the incident and exiting ions are isotopes of hydrogen and helium. This includes (p, α), (d, p), (d, α), (3He, p) and (3He, α) reactions that are used for analysis of many light elements including C, O, F and Al. The package optimises a suitably parameterized distribution of up to five isotopes using nonlinear least squares fitting. The package is written for the IBM PC in Turbo C and uses EGA and VGA graphical interfaces to overlay initial guess and final fits to the raw spectral data.

Flow cytometry signal processing and data acquisition with a personal computer using an RTI‐800 multifunction A/D I/O board

Abstract: The design and implementation of a data management system, consisting of a real‐time data processing and a PC‐based acquisition system, for measurement of flow cytometric data is described. The data processing system makes use of an erasable programmable logic device for implementation of dedicated control logic. The signal processing system is used for measuring the peak heights of 8 analog signals and simultaneous digital measurement of the time of flight. Four window discriminators are used for data selection and sorting applications. The data acquisition system is based on an MS‐DOS PC with a slightly modified commerical A/D I/O board, which we used to measure 8 analog signals (12 bit A/D converted) and 32 bit digital information per event. Using an IBM compatible personal computer with an 8 MHz AT bus, the total system is capable of measuring about 10 000 events per second.

Numerical Integration of Complex Chromatograms Using Fitted Gaussian Functions

Abstract: A microcomputer program is presented for the analysis and integration of peaks in chromatography using numerical gaussian fittings and repetitive peelings. The method is based on a IBM compatible PC microcomputer and Basic language. Data is transported to the computer from primary output curves of a chromatography device by a coordinate reader. This makes the system applicable to any chromatography apparatus. The program itself is adaptive to almost any IBM PC compatible microcomputer. The method was developed especially for the analysis of complex chromatograms with severely overlapped peaks. It was tested by using spectra of hemoglobin, obtained from cation exchange liquid chromatography.

Graphical user interface of RFX control and data acquisition system

Abstract: The paper presents the user interface aspects of the control and data acquisition system (SIGMA) of the RFX nuclear fusion experiment. SIGMA uses programmable controllers (PLCs) for slow signals and VAX based CAMAC for the fast data acquisition and timing tasks. The paper briefly summarises the technical aspects of the user interface: PLC based systems use operating consoles which employ IBM PC/AT compatibles running a commercial plant supervision package. The VAX based part employs VAXstations as user consoles with an extensive graphical user interface (initially DECwindows, now Motif). The use of these tools is illustrated by presenting the entire operation sequence for an RFX shot.

Event triggered data acquisition in the Rock Mechanics Laboratory

Abstract: Increasing complexity of experiments coupled with limitations of the previously used computers required improvements in both hardware and software in the Rock Mechanics Laboratories. Increasing numbers of input channels and the need for better graphics could no longer be supplied by DATAVG, an existing software package for data acquisition and display written by D. J. Holcomb in 1983. After researching the market and trying several alternatives, no commercial program was found which met our needs. The previous version of DATAVG had the basic features needed but was tied to obsolete hardware. Memory limitations on the previously used PDP-11 made it impractical to upgrade the software further. With the advances in IBM compatible computers it is now desirable to use them as data recording platforms. With this information in mind, it was decided to write a new version of DATAVG which would take advantage of newer hardware. The new version had to support multiple graphic display windows and increased channel counts. It also had to be easier to use.

A flexible IBM-PC based data acquisition system for nuclear physics experiments

Abstract: A SCSI-bus data acquisition module, which serves up to 15 12-bit NIM-standard spectroscopy ADCs, is described. When operating in cascade mode, 8 modules may serve up to 112 ADCs. The module was primarily developed for use in nuclear physics experiments. A typical system configuration consists of a data acquisition module, a SCSI-bus mass storage device (Video-8 or DAT) and a personal computer system controller. The latter also serves as a monitor allowing on-line evaluation of the quality of the incoming experimental data. The module has a micro-controller, a SCSI-bus controller and a field programmable gate array as main components. The gate array implements most of the ADC arbitration and read-out logic. The module was designed to allow a high degree of flexibility. This was accomplished by allowing the control programs and gate array configurations to be down-loaded from the system controller. The design thus permits rather extensive functional modifications without changing the hardware. It also allows thorough testing by down-loading test programs and test configurations.

Concept of virtual instruments applied in photoacoustic measurements

Abstract: A method is presented by which photoacoustic measurements can be done fast and with small effort. All operations are performed by an automatic measurement system based on an IBM PC personal computer. The structure and principles of the system operation are presented. The main advantages of the method described are: short time of measurement, wide chopping frequency range, high accuracy, and low error level. Owing to the computer some operations like hardware averaging, filtering, etc. can be replaced by software. This results in simplicity of the setup.

A computer-based language learning tool for the handicapped

Abstract: The needs of the vocally handicapped and the shortcomings of existing speech aids are identified in the context of how better speech aids may be obtained. The requirements for quadriplegics are discussed together with the alternatives to speech-aid keyboards. The problems and limitations of standard speech aid keyboards act as an introduction to the theme of software-generated-keys (softkeys). Softkeys are used in the human interface models developed to emulate a touch input speech aid. A speech board that can be driven from a standard IBM PC is described. The ultimate goal is that the same software program will present menus of information to the patient and receive an input choice from that patient in order to produce speech. The key factor is that any IBM PC compatible computer can be used to handle the user interface and the control of the speech board. >

A digital signal processing audiometric workstation

Abstract: The authors report on the development of a digital signal processing audiometric workstation based on a standard IBM PC and Motorola DSP56001 processor. The current system has functionality to test a patient's hearing using pure tone testing, FM tones, bandlimited noise, speech and white noise signals. Unlike most consumer DSP audio systems, the workstation uses 24 bit digital signals, which are then converted to analogue signals in an effort to produce a dynamic range much wider than the 88 dB nominally achieveable with 16 bit systems. Aside from the low level DSP functionality, the audiometric workstation has also been designed to be very easy to use by developing a Windows 3.1 based interface to provide a virtual instrument by duplicating the controls of a standard audiometer on screen. >

Using the PC architecture in embedded applications

Abstract: Originally intended for office desktops, the IBM PC (and PC/AT) architecture has become an extremely popular platform for a myriad of applications never dreamed of by its originators. These include communications devices, vending machines, test equipment, data acquisition and control products, and medical instruments. There are many reasons why embedded system designers would like to use the PC architecture embedded within their systems, including widespread availability of PC-compatible hardware, software, peripheral devices and development tools. Despite these advantages, however, normal desktop PC designs are not reliable enough for many kinds of embedded applications. Fortunately, a number of PC enhancements and extensions have been developed which solve these problems. This makes the PC architecture an important option for use in embedded system applications.

Multimedial data base and management system for self-education and testing the students' knowledge on pathomorphology.

This system is implemented on microcomputers compatible with IBM PC and works in network system Net Ware 3.11. The test questions exceeded 2000 until now. The packet consists of the two functionally individual programs: ASSISTANT, which is the administrator for the databases, and EXAMINATOR which is the executive program. This system enables to use text files and add images to each question, which are adjusted to display on standard graphics devices (VGA). Standard format of the notation files enables to elaborate the results in order to estimate the scale of answers and to find correlations between the results.

A PC add-on card for Mössbauer data acquisition system

Abstract: A user friendly Mossbauer data acquisition add-on card for IBM compatible PC has been designed and fabricated. It is a firmware which acquires data and shares the CPU of the host PC to transfer the data into the PC memory. The card generates the wave form for the drive unit, generates dwell time marker pulses and counts the energy selected single channel analyzer (SCA) pulses. The significant feature of the system is that the counting of the SCA pulses is done with two counters, resulting in zero dead time. Two temporary dual port RAMs (DP RAM) on board enable real time data acquisition. The software which controls the hardware is menu driven and user friendly and works under DOS environment. An on line display of the spectrum is provided with a cursor which enables the inspection of counts in any channel during the acquisition. The current version of the spectrometer has a capacity of 2048 channels and this can be extended easily up to 8192 channels.

Development of a real time Image analysis system for traffic monitoring applications.

Abstract: Image processing offers unparalleled potential for traffic monitoring and control. For many years engineers have attempted to perfect the art of automatic data abstraction from sequences of video images. This paper outlines a research project undertaken at Napier University by the authors in the field of image processing for automatic traffic analysis. A software based system implementing TRIP algorithms to count cars and measure vehicle speed has been developed by members of the Transport Engineering Research Unit (TERU) at the University. The TRIP algorithm has been ported and evaluated on an IBM PC platform with a view to hardware implementation of the pre-processing routines required for vehicle detection. Results show that a software based traffic counting system is realisable for single window processing. Due to the high volume of data required to be processed for full frames or multiple lanes, system operations in real time are limited. Therefore specific hardware is required to be designed. The paper outlines a hardware design for implementation of inter-frame and background differencing, background updating and shadow removal techniques. Preliminary results showing the processing time and counting accuracy for the routines implemented in software are presented and a real time hardware pre-processing architecture is described.
