The Immersed Boundary Method (IBM), originally developed by C.S. Peskin [Pes72], is a very practical method of simulating fluid-structure interactions. It combines Eulerian and Lagrangian descriptions of flow and moving elastic boundaries using Dirac delta functions. Incompressible Navier-Stokes and Elasticity theory can be unified by the same set of equations to get a combined model of the int...

OBJECTIVE The aims of the study were: (1) to evaluate subjective sleep quality and daytime sleepiness in patients affected by sporadic inclusion-body myositis (IBM); (2) to define the sleep and sleep-related respiratory pattern in IBM patients. METHODS Thirteen consecutive adult patients affected by definite IBM were enrolled, six women and seven men, mean age 66.2 ± 11.1 years (range: 50-80)...

We present a collision model for particle-particle and particle-wall interactions in interface-resolved simulations of particle-laden flows. Three types of interparticle interactions are taken into account: (1) long- and (2) short-range hydrodynamic interactions, and (3) solid-solid contact. Long-range interactions are incorporated through an efficient and second-order-accurate immersed boundar...

Since subsentential alignment is critically important to the translation quality of an Example-Based Machine Translation (EBMT) system which operates by finding and combining phrase-level matches against the training examples, we recently decided to develop a new alignment algorithm for the purpose of improving the EBMT system’s performance. Unlike most algorithms in the literature, this new Sy...

In his inaugural presidential address to the Population Association of America in 1978, Richard Easterlin challenged the orthodox neoclassical economic model of fertility originally suggested by Becker and subsequently elaborated by Becker and Lewis. While maintaining an economic approach to fertility, Easterlin's model was based upon the notion of material aspirations which changed systematic...

using cross-provinces and panel regressions, this paper investigates the interrelationship between gender equality and fertility in iran for the period 2007-2012. the article attempts to explain the low fertility rate in iran by distinguishing between two types of gender equity, i.e. gender equity in individual-oriented institutions and gender equity in family-oriented institutions. for this pu...

The paper describes an efficient communication support for the global address space programming model on the IBM SP, a commercial example of the SMP (symmetric multi-processor) clusters. Our approach integrates shared memory with active messages, threads and remote memory copy between nodes. The shared memory operations offer substantial performance improvement over LAPI, IBM one-sided communic...

The process of evolution involves the emergence and disappearance of species. Many factors affect on the survival of species. Real study of factors’ influence is particularly difficult due to the complex interaction between them. An individual-based model (IBM) can assist in the analysis of effective factors. In this study, using an IBM called EcoSim, we have examined the impact of some factors...

ften in our hurry to create the future in computer engineering, we ignore lessons from past projects. One project that offers interesting insights, the IBM System/360 Model 91, recently celebrated the 30th anniversary of its first shipment. The largest member of the series based on IBM’s most enduring and influential computer architecture, this machine owed much to its predecessors. Together, t...

"The population of China is still growing despite a dramatic decline in fertility in the past two decades. There are marked urban-rural differentials in fertility and, as a result, the pace of urbanization has significant effects on population growth. In this research an attempt is made to model urban-rural population growth in China. A demoeconomic model of urban and rural sectors is calibrate...
