Remarks on the Notion of Mean Free Path for a Periodic Array of Spherical Obstacles
نویسنده
چکیده
In this note, we explain in detail how the notion of mean free path is related to the mathematical results obtained in our previous paper DDG]. The purpose of this note is to clarify ambiguities concerning the notion of mean free path in our previous article DDG] and its companion paper BGW]. We are grateful to N. Chernov for bringing these ambiguities to our attention. However we should say that the ambiguous terminology does not aaect the mathematical results in DDG]. All the theorems, lemmas and corollaries in DDG] are true as stated, and do not explicitly refer to any deenition of mean free path.

On the mean free path for a periodic array of spherical obstacles
We prove theorems pertaining to periodic arrays of spherical obstacles which show how the macroscopic limit of the mean free path depends on the scaling of the size of the obstacles. We treat separately the cases where the obstacles are totally and partially absorbing, and we also distinguish between two-dimensional arrays, where our results are optimal, and higher dimensional arrays where they...
متن کاملA New Design of Log-Periodic Dipole Array (LPDA) Antenna
This paper presents a new approach for design of the log-periodic dipole array antenna (LPDA) based on using of different design parameters in the LPDA elements to control the antenna behavior. In the proposed procedure, the design parameters can control the value of forward gain over the operating frequency range, and also adjust the gain flatness. Furthermore, this design procedure can decrea...
متن کاملمسیریابی حرکت روباتهای ماشینواره با روش پیشروی سریع
The Robot Motion Planning (RMP) problem deals with finding a collision-free start-to-goal path for a robot navigating among workspace obstacles. Such a problem is also encountered in path planning of intelligent vehicles and Automatic Guided Vehicles (AGVs). In terms of kinematic constraints, the RMP problem can be categorized into two groups of Holonomic and Nonholonomic problems. In the first...
متن کاملLarge-eddy simulation of turbulent flow over an array of wall-mounted cubes submerged in an emulated atmospheric boundary-layer
Turbulent flow over an array of wall-mounted cubic obstacles has been numerically investigated using large-eddy simulation. The simulations have been performed using high-performance computations with local cluster systems. The array of cubes are fully submerged in a simulated deep rough-wall atmospheric boundary-layer with high turbulence intensity characteristics of environmental turbulent fl...
