This paper presents a highly parallelizable parallel-in-time algorithm for efficient solution of nonlinear time-periodic problems. It is based on the extension parareal method, known to accelerate sequential computations via parallelization fine grid. The proposed approach reduces complexity periodic by introducing simplified Newton algorithm, which allows an additional coarse In particular, at...

‎‎a natural generalization of two dimensional cyclic code ($t{tdc}$) is two dimensional skew cyclic code‎. ‎it is well-known that there is a correspondence between two dimensional skew cyclic codes and left ideals of the quotient ring $r_n:=f[x,y;rho,theta]/_l$‎. ‎in this paper we characterize the left ideals of the ring $r_n$ with two methods and find the generator matrix for two dimensional s...

The objective of the study presented herein is to access the influence of rupture directivity on the inducement of liquefaction in loose, saturated sand. Rupture directivity is a near fault phenomenon that results in a pronounced double-sided velocity pulse in the strike normal component(s) of motion. Using the Palmgren-Miner fatigue theory, implemented for low cycle fatigue conditions, the num...

BACKGROUND All of previous biomechanical studies on meniscal repair have examined the meniscus itself without synovial membrane and capsule, although in the clinical setting, the meniscal repair is generally performed including capsule. Therefore, biomechanical properties of transcapsular meniscal repair are unclear. Thus, this study aimed to clarify the biomechanical properties of transcapsula...

Array statements as included in Fortran 90 or High Performance Fortran (HPF) are a wellaccepted way to specify data parallelism in programs. When generating code for such a data parallel program for a private memory parallel system, the compiler must determine when array elements must be moved from one processor to another. This paper describes a practical method to compute the set of array ele...

We present a new, parallel version of the Numerical Electromagnetics Code (NEC). The parallelization is based on a bi-dimensional block-cyclic distribution of matrices on a rectangular processor grid, assuring a theoretically-optimal load balance among the processors. The code is portable to any platform supporting message passing parallel environments such as MPI and PVM where it could even be...

The addition of specific antigen to IgE-sensitized human lung tissue causes the secretion of the mediators histamine and slow-reacting substance of anaphylaxis. The mechanisms by which increased levels of cyclic AMP suppress and increased levels of cyclic GMP enhance this secretory process were studied. Colchicine, an agent which disrupts many secretory reactions by binding to microtubules in t...

Linear Scaling DALTON (LSDALTON) is a powerful molecular electronic structure program that is the focus of software optimization projects in PRACE 1IP-WP7.2 and PRACE 1IP-WP7.5. This part of the project focuses on the introduction of parallel diagonalization routines from the ScaLAPACK library into the latest MPI version of LSDALTON. The parallelization work has involved three main tasks: i) Re...

In this paper, we present two new algorithms in residue number systems for scaling and error correction. The first algorithm is the Cyclic Property of Residue-Digit Difference (CPRDD). It is used to speed up the residue multiple error correction due to its parallel processes. The second is called the Target Race Distance (TRD). It is used to speed up residue scaling. Both of these two algorithm...

objective: cell vital function has correlation with mechanical loadings that cell experiences. here, effects of in-vitro combined cyclic-static stretch on proliferation of human mesenchymal stem cell (hmsc) were evaluated. materials and methods: hmscs were cultured on gelatin coated elastic membranes, and exposed to stretch loading. four different regimes of cyclic, static, combined cyclic-sta...
