Concurrent quantitative laser-induced incandescence and SMPS measurements of EGR effects on particulate emissions from a TDI Diesel engine

A comparison of scanning mobility particle sizer (SMPS) and laser-induced incandescence (LII) measurements of diesel particulate matter (PM) was performed. The results reveal the significance of the aggregate nature of diesel PM on interpretation of size and volume fraction measurements obtained with an SMPS, and the accuracy of primary particle size measurements by LII. Volume fraction calculatio

Conclusions from the European Roadmap on Control of Computing Systems

The use of control-based methods for resource management in real-time computing and communication systems has gained a substantial interest recently. Applications areas include performance control of web-servers, dynamic resource management in embedded systems, traffic control in communication networks, transaction management in database servers, error control in software systems, and autonomic co

This thesis presents a new technique to prove the convergence of finite difference methods applied to nonlinear Systems arising in computational fluid dynamics. The underlying Systems are either hyperbolic such as the Euler equations or mixed hyperbolic-parabolic like the Navier-Stokes equations. We analyze implicit finite-difference methods. As the argument is based on the concept of consistency

Direct and inverse scattering from dispersive media

Direct and inverse scattering from dispersive media are studied in the time domain. The media are one-dimensional and homogeneous but can be impedance mismatched to the surrounding media. A time domain method is introduced where the reflection and transmission kernels are obtained from Volterra equations of the second kind. Numerical examples are given based upon both synthetic and measured data f
