the effect of traffic density on the accident externality from driving the case study of tehran
در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
15 صفحه اولA Jpeg Corner Artifact from Directed Rounding of Dct Coefficients
JPEG compression introduces a number of well known artifacts including blocking and ringing. We describe a lesser known or understood artifact consisting of a slightly darker or lighter pixel in the corner of 8×8 pixel blocks. This artifact is introduced by the directed rounding of DCT coefficients. In particular, we show that DCT coefficients that are uniformly rounded down or up (but not to t...

it is my great honor announcing the promotion of the archives of bone and joint surgery (abjs) to the level of being available on the pubmed central site. being precise, one year ago in september 2013, we published the first issue of the abjs. diligently thereafter, we published four subsequent issues with the fifth being in front of you. we set this as our first goal to reach visibility on pub...
متن کاملMeasuring Contact Hole Corner Rounding Uniformity Using Optical Scatterometry
Uniformity distribution of the corner rounding radius of curvature is investigated using reflectanceand transmittancebased optical scatterometry. Arrays of square contact holes are measured at multiple locations on an ACI photomask using a broadband spectrophotometer capable of collecting polarized reflectance (Rs and Rp) and polarized transmittance (Ts and Tp) spectra in 190 – 1000 nm waveleng...
