Antonia Maioni compared health care in the United States and Canada at the annual Palmer lecture series recently.

U.S. Secretary of Health & Human Services Michael O. Leavitt will be addressing government officials, educators, law professionals and clergymen from over 40 countries at this year's Law and Religion Symposium.

European Space Agency) After reaching the second-lowest extent ever recorded last month, sea ice in the Arctic has begun to refreeze in the face of autumn temperatures, closing both the Northern Sea Route and the direct route through the Northwest

Activities include concert, walk-a-thon, and dozens of marching bands

The problem considered in this paper is the optimisation of the gear-set of a race car in a virtual (software) environment. This task has been split into three sub-tasks: first, the maximum achievable speed (as a function of the local

A two-dimensional model with eight Degrees Of Freedom (DOF) is developed to simulate and animate the response of a vehicle to different road, traction, braking and wind conditions. An algorithm is developed to compute the normal force acting on each

One of the most vital factors in combustion control is Air-to-Fuel Ratio (AFR) estimation and control. In this work a detailed mathematical, nonlinear and control oriented model of dynamic processes of turbocharged diesel engines is presented. This model has been

This paper presents a methodology for detecting and tracking the progress of mechanical damage in vehicle suspension system components. The area entrained by restoring force diagrams is proportional to the magnitude of internal forces acting between two points of a

In this paper, a non-linear position tracking controller that globally linearises the dynamics of an electrohydraulic actuator is derived. This controller and a linear controller are both implemented in a decentralised manner within a simulation model of a four-post road

Occupant restraint system design is very important for passenger vehicles to improve passive safety performance. In this paper, an optimisation approach using MADYMO simulation is put forward for occupant restraint system design. Based on multi-body dynamics theory and the finite

Two non-linear differential equations representing road load and power consumption are used to determine the maximum vehicle speed and speed-time history. These equations are expressed in terms of velocity by expanding the inertia force, air drag, rolling resistance, gravitational force

This paper describes the design and functionality of an open-source object-oriented library for executing discrete-event simulation models in the Java programming language. The structure of the library is described in terms of its packages, class structure, and functionalities. The purpose

Vector Autoregressive (VAR) and Structural Vector Autoregressive (SVAR) models may be described as those models that explain, at least partially, the values of a set of variables, based on the past values of this set of variables. During recent decades,

The weighted Cramer-von Mises (CvM) estimator for the asymptotic variance parameter σ² of a steady-state simulation process has a number of desirable features. For certain weight functions, it is a first-order unbiased estimator of σ², and its variance is lower

Most of the current literature in supply chain inventory management focuses solely on series systems in which the analytical models become too complicated to be solved when considering various inventory policies concurrently. The authors present a new simulation-based approach to

Asynchronous Transfer Mode is a cell-oriented transfer mode based on asynchronous time division multiplexing. ATM manages different types of services with different requirements using cell structures and virtual channels and paths. Most of the proposals in terms of routeing algorithms,

This paper describes the application of an object-oriented (OO) modelling concept and OO programming mechanisms to develop an activity object-oriented (AOO) simulation strategy for modelling construction operations. The AOO simulation strategy considers construction activities to be objects, thus overcoming some

To address the dynamics of team effectiveness with the effect of interactions between task process and members, a multi-agent based model is developed with such concepts as member relation degree and member-task matching degree proposed to describe social relations among
