The history of public domain finite element models of the side impact anthropometric test dummy are summarized and recent improvements are briefly discussed. The performance of the two most recent finite element models are discussed with respect to the predictions of acceleration time histories as compared to standard bench calibration tests as well as an in-vehicle full-scale vehicle crash tes...

let $g$ be a group and $pi(g)$ be the set of primes $p$ such that $g$ contains an element of order $p$. let $nse(g)$ be the set of the number of elements of the same order in $g$. in this paper, we prove that the simple group $l_2(p^2)$ is uniquely determined by $nse(l_2(p^2))$, where $pin{11,13}$‎.‎

Ultra Wideband Antenna Array Processing Under Spatial Aliasing. (August 2007) Alireza Shapoury, B.S., Shahid Beheshti University of Iran; M.S., Iran University of Science and Technology Chair of Advisory Committee: Dr. Erchin Serpedin Given a certain transmission frequency, Shannon spatial sampling limit defines an upper bound for the antenna element spacing. Beyond this bound, the exceeded amb...

in this article, we propose and analyze a computational method for numerical solution of general two point boundary value problems. method is tested on problems to ensure the computational eciency. we have compared numerical results with results obtained by other method in literature. we conclude that propose method is computationally ecient and eective.

This paper analyzes the limits of applicability of the time domain surface impedance concept. Numerical results obtained by the boundary element formulation employing time domain surface impedance boundary conditions (SIBCs) of different orders of approximation are compared with experimental data and numerical results obtained using the finite element method. An analytical formula for evaluatio...

This paper presents a new method to improve the GBW (gain-bandwidth product) on negative feedback amplifiers. The proposed method is based on the introduction of time delay elements in the feedback loop, which can be exploited to retrieve significant bandwidth enhancements. This delayed feedback concept is analyzed, and considerations are presented for first order amplifiers, based on theoretic...

Safety and failure in gas pipelines are very important in gas and petroleum industry. For this reason, it is important to study the effect of different parameters in order to reach the maximum safety in design and application. In this paper, a three dimensional finite element analysis is carried out to study the effect of crack length, crack depth, crack position, internal pressure and pipe thi...
