In order to derive kinetic equations one starts from the Liouville-equation, which can be transformed into the BBGKY-hierarchy by reduction. Breaking off the hierarchy1-3 or evaluation of the hierarchy by B O G O L J U B O V ' S synchronization assumption 4 then leads to closed, explicitly time-independent equations of motion for the one-particle distribution function, which are called kinetic ...

Guards on machine tools are meant to protect persons from injuries caused by parts ejected with high kinetic energy from the machine's working zone. With respect to stationary grinding machines, Standard No. EN 13218:2002, therefore, specifies minimum wall thicknesses for guards. These values are mainly based on estimations and experience instead of systematic experimental investigations. This ...

Let M be a triangulated, orientable 2-manifold of genus g without boundary, and let h be a height function over M that is linear within each triangle. We present a kinetic data structure (KDS) for maintaining the Reeb graph R of h as the heights of M’s vertices vary continuously with time. Assuming the heights of two vertices of M become equal only O(1) times, the KDS processes O((κ + g)n polyl...

Ofloxacin is a highly efficient and widely used antibiotic drug. It classified as refractory pollutant due to its poor biodegradability. Consequently, it commonly found in water sources, requiring methods for removal. Advanced oxidation processes (AOPs) offer alternatives since those yield complete degradation not achieved adsorption or membrane processes. Previous studies suggest ofloxacin fol...

Many countries use liquefied petroleum gas (LPG) for various purposes, such as cooking and heating. As the population need energy grow, demand LPG steadily increases. This situation causes rise in imports with an insufficient local supply, including Indonesia. To overcome this problem, Indonesian Government plans to substitute fuel dimethyl ether (DME). However, stoves household burners widely ...
