Featured Case Studies
Improving Ultrasonic Tumour Therapy With Passive Acoustic Detection
Researchers at the University of Oxford developed a system for monitoring high intensity focused ultrasound (HIFU) surgery of cancerous tumours using ultrasonic hydrophone arrays. By combining NI PXI Express hardware and LabVIEW software, they achieved rapid data acquisition from a 32 channel custom array of sensors at 50MS/s.
Creating a Data Acquisition, Processing, and Monitoring System Based on LabVIEW for a Forced Oscillation Rig
Engineers at National Aerospace Laboratories built a highly reliable, user-friendly system to acquire, monitor, and process data in real time for the oscillating aerospace models in a 1.2 m Trisonic wind tunnel. They chose an NI PCI-4474 dynamic signal acquisition (DSA) module and an NI USB-9233 DSA module.
Using NI WSN and NI LabVIEW to Wirelessly Monitor Fatigue Damage on Highway Bridges
Researchers at the University of Texas built an economical and reliable system for real-time structural monitoring and fatigue analysis of highway bridges. Their low-power wireless sensor network system, built on NI WSN products, captures dynamic traffic-induced strains and performs real-time data analysis with a standard rainflow counting algorithm.
Trading Up: NASA Chooses NI SC Express for Accuracy, Flexibility in New Data Acquisition System
Using NI SC Express and PXI hardware, NASA scientists replaced legacy NEFF equipment in one of their largest human-rated environmental chambers with a data acquisition system capable of accurately synchronizing and measuring more than 500 analog channels.
Using LabVIEW and PXI for Deterministic Multiple Unit Vehicle Stability Control
Researchers at the Clemson University International Center for Automotive Research are using the NI PXI platform, M Series DAQ devices, and the NI LabVIEW Control Design and Simulation Module to prototype a multiple-unit vehicle measurement and control system. This system assesses the vehicle's dynamic state, evaluates system stability, and applies corrective actions to maintain stability.
Search Syntax Summary
| Operator | Example | Action | Boolean Equivalent |
|---|---|---|---|
| " " | "temperature monitoring" | Requires two terms to be adjacent to each other. In this example, only documents containing the phrase "temperature monitoring" will be shown. | ADJ |
| + | +temperature | Requires this term to be present as-is, eliminating the use of synonyms. This search query can be used in conjunction with other keywords to find only documents containing the word "temperature". | AND |
| - | -monitoring | Excludes results containing this term. Use this query in conjunction with other terms to find only documents not containing the word "monitoring" | NOT |
| () | (temperature monitoring) | Allows terms to be grouped when used with other operators. For example, searching for industrial -(temperature monitoring) will return only documents containing "industrial" but not "temperature" or "monitoring" | OR |
| * | monitor* | Acts as a wildcard. This example will return documents containing words "monitor", "monitoring", "monitored", etc | n/a |
Basic Tips
- Search is not case sensitive. Searching for LabVIEW is the same as searching for labview.
- Keep your query short and focused, including all relevant keywords. For example, searching for labview error is much more vague than labview error 1041.
- Usually, all punctuation and special characters are interpreted as delimiters and are ignored. See exceptions on the Syntax page. Be especially careful when using a minus sign in front of an error number, as it excludes it from the results.
- Search for keywords you would expect to see on a page. For example, terms pxi does not work are unlikely to appear in technical documentation. The query like analog output noise will return better search results.
Advanced Tips
- You locale settings identify your current geographical location and affect your search results. For example, if you set your country to Japan, Japanese documents will get boosted in your search results. Check your locale settings in the top right corner of the search page.
