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...

Water storage tanks not designed explicitly for seismic loading could require retrofit. One of the common ways of retrofit include some structural change in the lateral load resisting system that could be expensive and requires the tank to be out of service for relatively long time. This paper introduces a novel method to reduce seismic demand on tank’s wall without structural intervention. Thi...

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...

Cylindrical steel tanks are important components of many industrial plants such as oil refineries and chemical plants. Usually failure of cylindrical tanks leads to serious consequences. During the past earthquakes such as 1964 Alaska and 1999 Turkey seismic performance of cylindrical tanks revealed that tanks are seismically vulnerable. Therefore, evaluation of seismic performance of these str...

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...

Recently, a heat source system utilizing a heat storage tank for energy savings in buildings was designed. A heat storage tank is an effective system for solving the qualitative and quantitative differences in the required building energy. On the other hand, the existing design process of a heat storage system is difficult to determine if the air-conditioning time is unclear, and the design in ...

Bisphenol A (BPA) as a chemical hazard may enter the milk chain during primary production at farm and, successively, processing dairy company. To identify potential pathways that play role in occurrence of BPA, monitoring model for risk assessment based on identification hazards each stage was investigated. Milk samples were analyzed using liquid chromatography with fluorescence detection. Quan...

The utilisation of hydrogen in ships has important potential terms achieving the decarbonisation waterway transport, which produces approximately 3% world’s total emissions. However, drives maritime and inland shipping is conditioned by efficient safe storage as an energy carrier on ship decks. Regardless type, constructional design purpose aforesaid vessels, preferred method for currently high...
