PROGRESS OF THE COMMISSIONING OF THE TEST FEL AT MAX-lab

In a collaboration between MAX-lab and BESSY a test facility for Harmonic Generation Free Electron Laser is being constructed at MAX-lab. The setup uses the existing MAX-lab injector together with a Ti:Sa 263 nm laser system, used for both the gun and seeding, and an optical klystron consisting of a modulator, a chicane and a radiator. The different parts of the system have been installed and comm

The Autonomic Operating System Research Project - Achievements and Future Directions

Traditionally, hypervisors, operating systems, and runtime systems have been providing an abstraction layer over the bare-metal hardware. Traditional abstractions, however, do not consider for non-functional requirements such as system-level constraints or users' objectives. As these requirements are gaining increasing importance, researchers are looking into making user-specified and system-level

Why are expert committee deliberations in need of democratic control?

Abstract in UndeterminedThe aim of this paper is to argue for the need of democratic control of expert committees generally and ethical expert committees specifically. Expert committees including ethical expert committees with the commission to give advice to political decision-makers are often criticized for not being democratic. This criticism point at different aspects of expert committees: com

Circuit analogs for stratified structures

We present an overview of how circuit models can be used for wave propaga- tion in stratified structures. Homogeneous slabs are modeled as transmission lines, and thin sheets between the slabs are modeled as lumped elements. It is seen that electric material properties contribute as shunt elements, and mag- netic material properties contribute as series elements. When the sheets have periodic patt
