Arabic dialectology has a long history and achieved significant progress in collecting and analyzing linguistic data and its classification. The present paper analyses modern trends in the linguistic situation in the Arab world and defines the topics essential for the Arabic dialectology, which require an urgent solution. During the last century, several attempts have been undertaken to create ...
The functional magnetic resonance imagery responses of declarative memory tasks in the medial temporal lobe (MTL) are examined by using large deformation diffeomorphic metric mapping (LDDMM) to remove anatomical variations across subjects. LDDMM is used to map the structures of the MTL in multiple subjects into extrinsic atlas coordinates; these same diffeomorphic mappings are used to transfer ...
Maps of solar erythemal ultraviolet (EUV) irradiance daily doses were created for every month with a horizontal resolution of 500 m at the geographical domain 47.15 N–49.86 N×16.94 E–22.81 E covering the territory of Slovakia. The cloud modification factor for the EUV radiation (cmfUV ) was modeled utilizing the relation between the cloud modification factor of global and EUV radiation. The map...
IP anycast provides DNS operators and CDNs with automatic fail-over and reduced latency by breaking the Internet into catchments, each served by a different anycast site. Unfortunately, understanding and predicting changes to catchments as sites are added or removed has been challenging. Current tools such as RIPE Atlas or commercial equivalents map from thousands of vantage points (VPs), but t...
The purpose of the present paper is to discuss examples of aane Riemann surface laminations which do not admit a leafwise Euclidean structure. The rst example of such a lamination was constructed by Ghys Gh97]. Our discussion is based on the geometric methods developed by Lyubich, Minsky and the author LM97], KL01], which rely on the observation that any aane surface A gives rise in a natural w...
We use the ATLAS sample of 260 early-type galaxies to study the apparent kinematic misalignment angle, Ψ, defined as the angle between the photometric and kinematic major axis. We find that 71% of nearby early-type galaxies are strictly aligned systems (Ψ ≤ 5◦), an additional 14% have 5◦ < Ψ ≤ 10◦ and 90% of galaxies have Ψ ≤ 15. Taking into account measurement uncertainties, 90% of galaxies ca...
The objective of this study was to identify morphological measurements that best distinguish Moroccan Barcha and Atlas goat breeds. Ten measurements (body weight - BW, body length - BL, heart girth - HG, withers height - WH, rump height - WH, back length - BAL, neck length - NL, head length - HL, ear length - EL, and ear width - EW) of 876 adult animals of both sexes (547 Barcha and 329 Atlas) ...
For example, the Chernobyl accident caused the deposition of radioisotopes over wide areas of the Northern Hemisphere, in particular in Europe ( Atlas of Caesium Deposition on Europe after the Chernobyl Accident, 1998), followed by protracted chronic exposure of some millions of people to external and internal radiation. You can see the map of radioactive contamination of Europe after the Chern...
A new two-stage approach for nonlinear brain image registration is proposed. In the first stage, an active contour algorithm is used to establish a homothetic one-to-one map between a set of region boundaries in two images to be registered. This mapping is used in the second step: a two-dimensional transformation which is based on an elastic body deformation. This method is tested by registerin...
یکی از مسائلی که در سیستم sar مطرح می شود مسأله نویز speckle می باشد. منبع تولید نویز speckle فاز نسبی پراکنده گرهای مختلف در یک سلول رادار می باشد که نوسانات شدیدی در سیگنال دریافتی به وجود آورده و تصویر حاصل را دانه دانه می نماید. این نویز تفسیر تصاویر را مشکل و اطلاعات زیادی را مخفی می کند و لذا کاهش آن یکی از ملزومات در پردازش سیگنال sar است. الگوریتمهای متعددی جهت کاهش نویز speckle در نوا...
