A theoretical analysis based on some design considerations for surge tanks is carried out. The effects of different parameters such as the friction losses coefficient and the surge tank cross-sectional area on the water surface oscillations tank and the total discharge are investigated. System of non-linear ordinary differential equations are numerically solved and manipulated. Results show tha...

This study was conducted to investigate microbial community changes during the field-scale composting of the anaerobic digested pig manure sludge. Samples were obtained from an influent tank (Inf.) and anaerobic digestion tank (A. d.) of pig manure slurry, and the early stage of compost depot (Com. 1 and Com. 2). Input of the compost process was produced by the solid-liquid separation process o...

Water tank is used extensively for storing water, inflammable liquids and other chemicals. Generally, to provide water at large, tank is supported on frame or shaft (a vertical cylindrical shell). The staging with a single row of columns placed straight (vertical) along the periphery of circle or shaft, are generally adopted for elevated water tanks to support the tank container. Apart from ver...

This work investigated the behaviors of seven glucocorticoids, eight androgens, and nine progestogens compared to six estrogens in a municipal sewage treatment plant (STP) in Beijing, China. Among all of the hormones considered, androgens were the dominant steroids detected in all samples (total concentrations up to 10 216±912 ng/L for influents, 171±10 ng/L for effluents, and 647±52 ng/g for d...

odor emission is a common environmental problem in septic tank. the feasibility of using trickling filter to eliminate the malodorous gases from the septic tank was studied. a trickling filter is set up at the outlet of the waste gases of the septic tank, which was attached to the university's cafeteria. in this investigation, the trickling filter system was used, measuring the hydrogen sulfide...

This paper proposes novel Fuel Cell Auxiliary Power Unit (FCAPU) for J150+ aircraft application. The primary version of APU in J150+ aircraft is a gas turbine Auxiliary Power Unit (APU) which is based on gas turbine jet engine but in the suggested FCAPU, the generated electrical power is achieved from chemical energy with higher efficiency. The Solid Oxide Fuel Cell (SOFC) technology is used to...

This talk1 (a joint work with Philippe Flajolet) presents an algorithm to approximate count the number of different words in very large sets or texts (in the range of billions of bytes) and its analysis. When using an auxiliary memory of m bytes, the accuracy is of the order 1/ √ m. The analysis of this new algorithm relies on asymptotic Depoissonization techniques.

The BAS CLARIN speech data repository is introduced. At the current state it comprises 31 pre-dominantly German corpora of spoken language. It is compliant to the CLARIN-D as well as the OLAC requirements. This enables its embedding into several infrastructures. We give an overview over its structure, its implementation as well as the corpora it contains.

Bavarian Archive for Speech Signals (BAS), Ludwig-Maximilians-Universität München, Schellingstr. 3, 80799 München, Germany schiel|[email protected] Abstract Speech uttered under the influence of alcohol is known to deviate from the speech of the same person when sober. This is an important feature in forensic investigations and could also be used to detect intoxication in the auto...

We have developed a policy-based decision framework that provides authorization and cost-based accounting in the EZGrid system, a resource broker for metacomputing. Primarily, this work allows the administrators and the owners to exercise more control over their resources by dictating usage permissions and/or restrictions in a grid environment. This mechanism is independent of the applications ...
