New methods of degradations on the pavement’s surface, such as top-down cracking and delamination, caused by repeated passage heavy vehicles led to questions about impact contact between tire pavement. In fact, increase service life structures, future road design must have a precise knowledge consequences parameters state stress deformation in this paper, tractive rolling under effect friction ...

ABSTRACT We investigate the cosmological evolution of interstellar dust with a semi-analytical galaxy formation model (ν2GC), focusing on grain size distribution. The predicts statistical properties mass and distribution in galaxies across cosmic history. confirm that reproduces relation between dust-to-gas ratio metallicity local Universe, distributions Milky Way (MW)-like sample become simila...

In this note, we point out a mistake in Theorem 1 of De Gennaro Aquino and Bernard (Decis Econ Finance 42(2):715–741, 2019) provide some missing references where the problem pricing barrier options under Heston model had previously been discussed.

A new semi-analytical approach to estimate the influence of directly modulated semiconductor laser noise on direct detection system performance is proposed and its accuracy is analysed utilizing rigorous mixed semi-analytical simulation. It is shown that this new semi-analytical approach gives a more precise upper bound than the one obtained by other approach currently used, and differences of ...

Abstract—This paper presents new semi-analytical expressions to calculate the self-inductance and the electromagnetic force for a ferromagnetic cylinder of finite length placed inside a circular coil of rectangular cross section. The proposed analytical model is based on boundary value problems with Fourier analysis. Laplace’s and Poisson’s equations are solved in each region by using the separ...

در این پایان نامه روش جدیدی مبتنی بر روش حل معادلات دیفرانسیل پارهای بر اساس روش توابع پایه برای حل مسایل ارتعاش اجباری واستاتیک تیرها و صفحات لایه ای ارایه شده است که می توان تفاوت این روش با روش های متداول توابع پایه را در استفاده از توابع هموار در ارضاء معادلات حاکم و شرایط مرزی دانست. در روش ارایه شده در این پایاننامه از معادله تعادل به عنوان معادله حاکم بر رفتار سیستم استفاده شده است که مو...

We revisit the Milky Way satellite problem using a semi-analytical model of galaxy formation and compare the predicted luminosity function to recent result from the SDSS. With cosmic photoionization, the luminosity function can be brought into broad agreement with the data between −15 < MV < −2. This improvement over previous semi-analytical model results (e.g., Benson et al. 2002) is from our ...
