High Quality Thermostat Control by Reinforcement Learning A Case Study Martin Riedmiller Institut f ur Logik, Komplexit at und Deduktionssysteme Universit at Karlsruhe, D-76128 Karlsruhe, Germany e-mail: [email protected] Abstract| Temperature control is an important issue in many manufacturing processes. The requirement for high precision, fast reaction to disturbances, time delays of varyi...

An intensity-based fiber-optic liquid-level gauge for continuous measurement is described. The sensing principle is based on the total internal reflection of light within the fiber optic, and for this, a measurement is made of the power attenuation which occurs in the fiber optic immersed in the liquid tank when the liquid level varies. The light from a LED is modulated before being directed in...

The caterers will be serving a ‘surprise drink’ at the upcoming AMSI BBQ on Friday. To make this concoction, they have to mix a special liquid, which is soluble in water, with large amounts of water. Specifically, they pump these two different liquids via two separate hoses into a large cylindrical container and these liquids are mixed together with an electric stirrer situated inside the conta...

energy consumption is very high in greenhouses mainly due to off-season production. the main source of its energy supply is fossil fuels. due to the disadvantages of fossil fuels consumption and preventive laws in the incoming years, study on reducing consumption and replacing a part of them with renewable energy is essential. in this research, a solar heating system, equipped with a concentrat...

An important aspect of extraction using an organic solvent that is often ignored in many laboratory scale studies is thorough solvent recovery. Although most of the solvent can be recovered with a centrifuge, the solvent left on the ‘dry’ stream must be evaporated. A custom built pilot-scale settling tank was used to separate maize particles from ethanol extracts into water with little dilution...

The two-tank system is the technology used for thermal energy storage (TES) in current concentrating solar power (CSP) plants. Thermocline storage concept has been considered for more than a decade as a possible solution to reduce the high cost of the storage system in these plants. In previous works, multi-layered solid-PCM (MLSPCM) thermocline-like storage tank configurations has been introdu...
