Recovering the Primordial Density Fluctuations: a Comparison of Methods
We present a comparative study of different methods for reversing the gravitational evolution of a cosmological density field to recover the primordial fluctuations. We test six different approximate schemes in all: linear theory, the Gaussianization technique of Weinberg (1992), two different quasi-linear dynamical schemes (Nusser & Dekel 1992, Gramann 1993), a hybrid dynamical-Gaussianization...
متن کاملExtracting primordial density fluctuations
The combination of detections of anisotropy in cosmic microwave background radiation and observations of the large-scale distribution of galaxies probes the primordial density fluctuations of the universe on spatial scales varying by three orders of magnitude. These data are found to be inconsistent with the predictions of several popular cosmological models. Agreement between the data and the ...
متن کاملon the comparison of keyword and semantic-context methods of learning new vocabulary meaning
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
15 صفحه اولPrimordial Density Fluctuations in Phase Coupling Gravity
In this paper we study the evolution of primordial density perturbations in the framework of Phase Coupling Gravity, proposed by Bekenstein [1]. We show that in the very early universe, these perturbations grow with an exponential-like behaviour PACS: 98.80.-k, 04.50.+h e.mail: [email protected] e.mail: [email protected]

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...
