air spindles are one of the main elements of precise machine tools. vibration of these spindles is one of the vital issues necessary for investigation. among parameters which influence air spindle vibrations are rotational speed, compression air method, input nozzle diameter, air gap pressure. in this study using ansys, the effects of air gap thickness on air spindle vibrations have been invest...

The mapping of air quality over the city of Strasbourg and its vicinity requires an increase of the number of measurements aiming at spatializing information about air pollutants concentrations. A methodology based on a multisource approach for mapping air pollutants concentrations over the city was presented in previous communications. One step of the methodology is the estimation of pollutant...

background: in the past few decades, indoor air pollution (iap) has become a primary concern to the point. it is increasingly believed to be of equal or greater importance to human health compared to ambient air. however, due to the lack of comprehensive indices for the integrated assessment of indoor air quality (iaq), we aimed to develop a novel, fuzzy-based indoor air quality index (fiaqi) t...

Indonesian is located in the equatorial region,between continents of Asia and Australia which exclusively connects economies developed countries. In addition, Indonesia also between 2 oceans, namely Pacific Indian Ocean, makes a connecting area countries East Southeast South Asia. The purpose this study to find out: (1) problems solving regarding emergence maritime terrorism issues from social ...

a four year long research programme divided into four phases has been designed for the first time to assess the combined noise-air quality and combined exposure to noise-air pollution at the curbside open-air microenvironment of kolkata city, india. the results and the findings of the different phases of study had already been published. the objective of the review work is to fuse the findings ...

This paper gives a detailed analysis of the Cannon–Thurston maps associated to a general class of hyperbolic free group extensions. Let F denote a free groups of finite rank at least 3 and consider a convex cocompact subgroup Γ ≤ Out(F), i.e. one for which the orbit map from Γ into the free factor complex of F is a quasi-isometric embedding. The subgroup Γ determines an extension EΓ of F, and t...

We study Fermi edge singularities in photoabsorption spectra of generic mesoscopic systems such as quantum dots or nanoparticles. We predict deviations from macroscopic-metallic behavior and propose experimental setups for the observation of these effects. The theory is based on the model of a localized, or rank one, perturbation caused by the core hole left behind after the photoexcitation of ...
