6. Aspects on measuring electrical current utilizing magnetic zero-flux technique
Sammanfattning : The utilization of high accuracy measurements of electrical quantities is a prerequisite for the development of modern society. Generally, measurements serve different purposes and hence the criteria for the measurement equipment and method are different. LÄS MER
7. Spindle vibration and sound field measurement using optical vibrometry
Sammanfattning : Mechanical systems often produce a considerable amount of vibration and noise. To be able to obtain a complete picture of the dynamic behaviour of these systems, vibration and sound measurements are of significant importance. Optical metrology is well-suited for non-intrusive measurements on complex objects. LÄS MER
8. Computational methods for on-line shape inspection
Sammanfattning : This licentiate thesis describes computational methods that solve problems occurring in industrial on-line shape quality inspection of produced items. These items are measured and compared with their corresponding CAD object. The meaning of on-line is that the inspection is done on-line in the production line, i.e. LÄS MER
9. Evaluation of hand skin temperature : Infrared thermography in combination with cold stress tests
Sammanfattning : AbstractSince ancient times, warm or cold skin on the human body has been used as a parameter in evaluating health. Changes in body temperature are attributed to diseases or disorders. The assessment of body temperature is often performed to measure fever by detecting an elevated core temperature. LÄS MER
10. Machine tool vibrations and violin sound fields studied using laser vibrometry
Sammanfattning : The knowledge of the dynamic behaviour of a milling process is very important for finding an optimum process window. In today's manufacturing industry the machining parameters are often predicted using experimental data from non-rotating spindles. LÄS MER
