LabView Based AC Magnetization Characteristics and Measurement for Soft Magnetic Materials
This paper presents LabView based method combined with a simple analog circuitry to characterize the ac magnetization profile of soft magnetic materials. First, soft magnetic materials prepared as ring cores are wound with equal number of turns for the primary and secondary windings. The primary winding is excited with sinusoidal supply of varying voltage amplitude. The secondary winding is interfaced with the LabView for data acquisition and calculation. Graphical plotting and viewing of the hysteresis loop exhibited by the soft magnetic materials under test can be achieved using National Instrument NI6009 data acquisition card and LabView software. This research discusses the methods of measurement for flux density, magnetic field intensity and core permeability at different points of the ac magnetization. The measured results are then compared with those given by the manufacturer datasheets. Good agreement has been achieved to validate the proposed LabView based method
Implementation of IMMPDAF Algorithm in LabVIEW for Multi Sensor Single Target Tracking
Real time IMMPDAF algorithm has been implemented and tested in LabVIEW. Single aircraft flight profiles have been simulated and the plot data from multiple radars observing the single aircraft are generated with noise as well as clutter. The performance of the algorithm is evaluated using standard procedures. Since it is implemented and tested in LabVIEW, this algorithm can be easily realized in hardware for real time tracking applications

Introducing instrumentation and data acquisition to mechanical engineering students using LabVIEW
For several years, LabVIEW has been used within the Department of Mechanical Engineering at the University of Strathclyde as the basis for introducing the basic concepts and practice of data acquisition, and more generally, instrumentation, to postgraduate engineering students and undergraduate project students. The objectives of introducing LabVIEW within the curriculum were to expose students to instrumentation and experimental analysis, and to create courseware that could be used flexibly for a range of students. It was also important that staff time for laboratory work be kept to manageable levels. A course module was developed which allows engineering students with very little or no previous knowledge of instrumentation or programming to become acquainted with the basics of programming, experimentation and data acquisition. The basic course structure has been used to teach both undergraduates and postgraduates as well as laboratory technical staff. The paper describes the objectives of the use of LabVIEW for teaching, the structure of the module developed, and the response of students who have been subjected to the course, and how it is intended to expand the delivery to greater student numbers
An open source LABVIEW platform for simulating image series of fluorescent microtubules in gliding assays
We describe an open-source LabVIEW software platform for generating simulated images of microtubules in gliding motility assays. We describe how the software works and how to obtain the software
Integrating LabVIEW into a Distributed Computing Environment
Being easy to learn and well suited for a self-contained desktop laboratory
setup, many casual programmers prefer to use the National Instruments LabVIEW
environment to develop their logic. An ActiveX interface is presented that
allows integration into a plant-wide distributed environment based on the
Experimental Physics and Industrial Control System (EPICS). This paper
discusses the design decisions and provides performance information, especially
considering requirements for the Spallation Neutron Source (SNS) diagnostics
system.Comment: 3 pages, 2 figures, 8th International Conference on Accelerator and

Control Infrastructure for a Pulsed Ion Accelerator
We report on updates to the accelerator controls for the Neutralized Drift
Compression Experiment II, a pulsed induction-type accelerator for heavy ions.
The control infrastructure is built around a LabVIEW interface combined with an
Apache Cassandra backend for data archiving. Recent upgrades added the storing
and retrieving of device settings into the database, as well as ZeroMQ as a
message broker that replaces LabVIEW's shared variables. Converting to ZeroMQ
also allows easy access via other programming languages, such as Python
