The Dynamic Behaviour of the Instrumented Charpy Test
The dynamic characteristics of the Charpy test have been studied by means OF a Hopkinson bar apparatus and photoelasticity. It is Found that this technique permits a clear evaluation of the test results, and is preferable to the standard instrumented pendulum test.
متن کاملDesign Considerations for Adaptive Lighting to Improve Seniors' Mood
The advance of LED technologies allows for new design opportunities in the area of lighting for psychological health. Research has shown that lighting in various colors and intensities can be used to improve people’s moods, e.g. through its effects on melatonin levels. This is especially interesting in the context of ambient assisted living and care environments where people are less mobile and...
متن کاملExperimental Assessment of the Equivalent Strain Rate for an Instrumented Charpy Test
Instrumented Charpy test data can be used to obtain estimates of dynamic yield strength, by means of a well-established relationship published by W. Server in 1978. A fundamental issue in comparing measured dynamic tensile properties and Charpy-based estimations is establishing the equivalent uniaxial strain rate for an instrumented Charpy test, typically conducted at ≈ 5.5 m/s. In this investi...
متن کاملDesign Considerations for a Conventional Microscope based Microarray-Reader to Improve Sensitivity
An unmodified wide-field fluorescence microscope system equipped with a scientific grade CCD camera can be used to measure fluorescent signals in subnanoliter vials. The lowest detectable fluorescence signal in a 0.8nl vial of 200 × 200 × 20μm corresponds to a concentration of fluorescent molecules on the order of a nanomolar (10−9M ) for a dye such as Rhodamine. This paper will explain that th...
متن کاملDesign considerations to improve cognitive ergonomic issues of unmanned vehicle interfaces utilizing video game controllers.
Unmanned (UAVs, UCAVs, and UGVs) systems still have major human factors and ergonomic challenges related to the effective design of their control interface systems, crucial to their efficient operation, maintenance, and safety. Unmanned system interfaces with a human centered approach promote intuitive interfaces that are easier to learn, and reduce human errors and other cognitive ergonomic is...
