TreeView : an application to display phylogenetic trees on personal computers

Abstract: TreeView is a simple, easy to use phylogenetic tree viewing utility that runs under both MacOS (on Apple Macintosh computers) and under Microsoft Windows on Intel based computers, the two most common personal computers used by biologists. Some phylogeny programs, such as PAUP (Swofford, 1993) and MacClade (Maddison and Maddison, 1992) already provide excellent tree drawing and printing facilities, however at present these programs are restricted to Apple Macintosh computers. Furthermore, they require the user to load a data set before any trees can be displayed which is inconvenient if the user simply wants to view the trees. More portable programs, such as DRAWGRAM and DRAWTREE in the PHYLIP package (Felsenstein, 1993) can run on both MacOS and Windows computers, but make little, if any use of the graphical interface features available under those operating systems. TreeView runs as a native application on either MacOS or Windows computers, enables the user to use the standard fonts installed on their machine, their printer, and supports the relevant native graphics format (PICT and Windows metafile) for either creating graphics files or pasting pictures to other applications via the clipboard. The program also supports standard file operations, such as 'drag and drop' whereby dragging a file's icon onto the program opens that file. TreeView can read a range of tree file formats (see below) and can display trees in a range of styles (Fig. 1). Additional information, such as edge lengths and internal node labels can also be displayed. The order of the terminal taxa in the tree can be altered, and the tree can be rerooted. If the tree file contains more than one tree the user can view each tree in turn. The program can also save trees in a variety of file formats, so that it can be used to move trees between programs that use different file formats.

Feature-based design of progressive press tools

Abstract: This paper outlines two approaches for the development of a feature-based system which is used to support the detailed design of progressive press tools. The first approach is based on applying a coding technique to characterize the workpiece geometric features. This feature description is subsequently used to propose the type and layout of the press tool punches required to produce the part. The second approach uses design constraints as the bases for selecting the punches and dies. The approaches have been implemented on an IBM PC in C and integrated with a prototype low-cost CAD system for press tool design.

Programming without programming: The system Butterfly for professional psychologists

Abstract: This paper describes a system for creating and running adaptive psychological experiments on IBM PC compatible computers. The system is a collection of programming routines for IBM PC machines (text mode) that allows psychologists to create and edit experiments, collect and handle data, and transfer data into other systems without any programming. Stimulus variables include location, character, time, color, and sound. A special set of criteria is designed to conduct adaptive studies, such as operant conditioning experiments, in which experimental trials must be modified on the basis of a subject’s performance. The system supports multidimensional structural responses with feedback. Reaction and response time and the response contents can be collected from the keyboard, mouse, and game port.

An optical encoder and XY oscilloscope interface for the IBM PC

Abstract: This paper outlines a prototype dual-purpose interface card for the IBM PC for use in research on motor learning and control. The card enables automatic interfacing for up to four angular optical encoders and presents high-speed visual data on an XY oscilloscope. In addition, it uses two single-chip microcontrollers with minimal external hardware, providing a more powerful instrument than is available in discrete hardware. Two microcontrollers operate independently of the experimental computer (IBM PC), using a common interface allowing the exchange of data. This interface card frees the experimental computer from the workload associated with optical encoders and high-speed XY displays, resulting in less complex experimental setups and data collection programs.

A PC-based software tool for statistical pattern classifier design

Abstract: Interactive software systems for pattern analysis and recognition represent powerful scientific, research and development tools for pattern recognition system design. In this paper, we discuss one such scientific software system, named PC-PARIS (Pattern Analysis and Recognition Interactive System for PC compatible computers). A variety of pattern recognition and clustering algorithms, implemented in PC-PARIS, is briefly described. As application examples, we present sensitivity analysis of statistical pattern classifiers, implemented in PC-PARIS, to the increasing number of features in the limited training data set conditions, for both synthesized and real data classification.

Comparing interfaces: should we assume that ease of use influences users' preference?

Abstract: This paper reports a comparison of student preference for GUI and CLI interfaces as exemplified by the Apple Macintosh and IBM PC compatible. The paper considers one of the basic assumptions of interface research namely, that users will prefer the interface they find easier to use. The assumption has previously been considered intuitive, and there has been little research to consider the validity of such an assumption. This paper presents a summary of a quantitative analysis to show that the assumption is correct.

Application of Graphical Workstation SGI INDY and IBM PC to Rendering and Visualization of the Objects Captured by a Confocal Microscope

Abstract: Kubinova L.. 1. Janacek. K. Anto~. B. Jetek. M. Indra. D. Jirlik. I. Krekule: Application of Graphical Workstation SG11NDY and IBM PC to Rendering and Visualization of the Objects Caplllred by a Confocal Microscope. Acta vet. Bmo 1996,65:253-262. The options of several software packages for 3D rendering and visualization of objects captured by a confocal microscope were illustrated by the study of placental terminal villi and tobacco cell chains. Different types of 3D rendering were shown and discussed. It was concluded that software packages developed for solving general problems of medical imaging are well applicable to confocal data. 3D rendering, confocal microscopy, placelllal ferminal villus, tobacco cell chain The introduction of computed tomography in X-ray medical imaging in the seventies, later into nuclear medicine, magnetic resonance imaging and recently into ultrasound and infrared imaging represented a decisive impetus and objective for the development of medical imaging in the field of 3D object rendering and visualization (see, e.g. U dupa and Herman 1991). The later was enhanced by an interactive manipulation with the display of the object, including rotation, user control of the transparency, colouring, illumination, reflection, etc. of the visualized object, i.e. the organ and its constituents under study. All these attempts were supported by advances in understanding human visual perception (He rs c h et al. 1995; Roki ta 1996) and achievements in 3D computer graphics (e.g. Glassner 1990), the latter being stimulated by accelerating progress of the computer hardware in general and in its support to computer graphics. In principle, there are two distinctive types of 3D object rendering, i.e. surface rendering and volume rendering. The first type of rendering, displaying shaded surfaces of the object, produces pictures of the object similar to its images as perceived by the human eye, while volume rendering provides pictures similar to x-ray because optical properties of the material lying on the ray passing through the object into the observer's eye are taken into account. In maximum projection, a simplified version of volume rendering, only the voxel ·f maximum grey value along the given ray is displayed. The most simple type of surface rendering is represented by wire-frame reconstruction when only sets of contours of profiles of the object and its constituents are displayed. The simplicity of this approach means that the software needed is often home-made in laboratories (e.g. Spacek 1994). The wireframe visualization is also used in professional software packages for 3D rendering to present on-line results of an interactive manipulation (e.g. rotation) with the object before its surface or volume rendering is actually accomplished. Rendering and visualization of a tissue captured by a confocal microscope is not complicated when compared with some sofisticated problems of contemporary medical imaging, e.g. multimodal imaging (when images of the same object recorded by different cchnologies are fused, see e.g. Beolchi and Kuhn 1995) because the series of optical

Adaptive control of a one link geared robot

Abstract: In this paper, a simple one degree of freedom robot, designed for both research and teaching purposes, is described. An experimental set-up consists of a DC motor, a rate generator, a harmonic drive, a control system, and a load. The system has an open architecture and allows the programmer to distribute the intelligence between the single board computer (SBC) and PC compatible computer, which are connected through an interface. The SBC collects data from different sensors. System software resides on the SBC and PC compatible computer. Different friction characteristics of the harmonic-drive transmission are presented. A PID controller has been designed and successfully implemented. Different adaptive control algorithms were developed and tested both on a SUN workstation and on an experimental set-up.

IBM PC controller for Bruker EN250 ENDOR system

Abstract: Module upgrading the existing IBM PC data acquisition and processing system for Bruker ER200D equipped with EN250 ENDOR attachment is described. The old ASPECT 2000 computer is fully replaced by a modern IBM PC without any modification of the Bruker EN003 ENDOR standard interface. Thus the spectrometer can operate under IBM PC control in ENDOR and TRIPLE modes. Moreover its features are extended with ENDOR INDUCED EPR operating mode which was not available before.

Graphical coordination of overcurrent protection devices using a desktop computer

Abstract: An interactive computer program has been developed that assists with the coordination of overcurrent protection devices. An engineer can enter relay or fuse settings, view the resulting characteristic curves on the computer's graphical display, evaluate the coordination of the overcurrent protection devices, and save the data used for both the protection devices and the substation. The program runs on an IBM PC/AT or compatible computer with a VGA interface, but was written in the C programming language so that it could easily be recompiled for another machine.

Real-time implementation of an adaptive control system for a 3-zone rapid thermal processing station

Abstract: In this thesis, the implementation details of a real time adaptive control system for a TI 3-zone RTP station, as well as the simulation and the experimental results are presented. Extensive simulation of the system is performed in order to ensure proper operation of the system. The experimental results are used to verify proper operation of the closed loop control system. Initial experiments were conducted using two thermocouples. Further experiments were conducted using one thermocouple for the purpose of testing the performance of the system using Extended Kalman Filter as the state estimator. The implementation of the control system is carried out on an IBM compatible PC hosting a Transputer parallel -processing system. The motivation for utilizing the parallel processing system is to ensure future extensibility of the system. The eventual incorporation of a remote temperature sensing method such as Multi-Wavelength Imaging Pyrometer (M-WIP) will require great deal of computing power from the system. The implementation of the software for the system is also carried out with goal of providing ease of maintenance and extensibility. The implementation of graphical user environment also provides to the user point and click operation of the system as well as real time plotting capability.
