the main objective of the research is to study noise pollution in khorram abad, presenting executive strategies to control or reduce it. therefore, 38 stations were selected at the region to measure the noise level round-the-clock, and the samples were also taken for a week in the middle of spring and summer, 2007. the measurements were carried out during the day (7:00 am to 10:00 pm) and night...

Noise annotation lines are a promising technique to visualize thematic uncertainty in maps. However, their potential has not yet been evaluated in user studies. In two experiments we assessed the usability of this technique with respect to a different number of uncertainty levels as well as the influence of two design aspects of noise annotation lines: the grain and the width of the noise grid....

Comparing protein structures based on their contact maps is an important problem in structural proteomics. Building a system for reconstructing protein tertiary structures from their contact maps is one of the motivations for devising novel contact map comparison algorithms. Several methods that address the contact map comparison problem have been designed which are briefly discussed in this th...

We consider dissipative systems resulting from the Gaussian and alpha-stable noise perturbations of measure-preserving maps on the d dimensional torus. We study the dissipation time scale and its physical implications as the noise level ε vanishes. We show that nonergodic maps give rise to an O(1/ε) dissipation time whereas ergodic toral automorphisms, including cat maps and their d-dimensional...

Abstract We analyze the properties of Padé and conformal map approximants for functions with branch points, in situation where expansion coefficients are only known finite precision or subject to noise. prove that there is a universal scaling relation between strength noise order at which breaks down. illustrate this behavior some physically relevant model test two non-trivial physical examples...

We have compared cosmic microwave background (CMB) maps made from one-year time ordered data (TOD) streams that simulated observations of the originally planned 100 GHz P Low Frequency Instrument (LFI). The maps were made with the ROMA, MapCUMBA and destriping algorithms. We produced angular power spectrum estimates from the ROMA and destriping maps and compared them as well. ROMA and MapC...

We study destriping as a map-making method for temperature-and-polarization data for cosmic microwave background observations. We present a particular implementation of destriping and study the residual error in output maps, using simulated data corresponding to the 70 GHz channel of the Planck satellite, but assuming idealized detector and beam properties. The relevant residual map is the diff...
