Development of a cryogenic index of refraction measuring device

Using a digital camera as a measuring device

We present several experiments that can be done using a digital camera or a webcam, including the shapes of shadows cast by lampshades, the trajectories of water jets, the profile of a hanging chain, and caustic figures produced by the reflection of light on mirrors of different forms. The experiments allow for a simple and direct quantitative comparison between theory and experiment. © 2006 Am...

Twin Plate Weir: A Flow Measuring Device (TECHNICAL NOTE)

For efficient use of water, accurate measurement of flow in (field/laboratory) channels is required for many water resource projects. The present work is aimed to study the flow characteristics of a twin plate weir (two sharp-crested plates are placed one behind the other at some distance) under free and submerged flow conditions. Experiments are performed with four spacing of the twin plate we...

Information Background for Development of a Measuring Device

Precision agriculture applies up-to-date technologies, which require the exact setting and professional operation of the applied machines. All this presupposes a sound knowledge of the characteristics of treated granular particles. This includes the key importance of the knowledge of physical and mechanical characteristics of particles (size, shape, density, moisture content, friction character...
