Photoelectron Diffraction: from phenomenological demonstration to practical tool

Developing a Practical Programming by Demonstration Tool

Many iterative tasks in direct manipulation interfaces cannot be automated with standard application tools, forcing users to repeat the same interface actions again and again. We describe a domain-independent programming by demonstration system that learns iterative tasks in a range of widely-used applications on a popular computer platform. An evaluation showed that users are capable of using ...

Photoelectron diffraction mapping: molecules illuminated from within.

We demonstrate the use of a multiparticle coincidence technique to image the diffraction of an electron wave whose source is placed at a specific site in a free molecule. Core-level photoelectrons are used to illuminate the molecule from within. By measuring the vector momenta of two molecular fragments and the photoelectron, a richly structured electron diffraction pattern is obtained in a bod...

Path-reversed Auger electron and photoelectron diffraction

We propose a method for the computer simulation of Auger electron and photoelectron diffraction patterns by evaluating the amplitude of propagation paths from the detector to the electron-emitting source, justified by Helmholtz’s reciprocity principle. The method offers significant computational advantages over previous schemes, and suggests an easy extension to enable the calculation of a stru...

Welcome from the Tool Demonstration Chairs

The Tool Demonstration Track at CSMR 2012 provides an opportunity for researchers to present novel research tools for software maintenance and reengineering. Eight tools which aim to aid software developers and maintainers in their work have been selected for presentation and demonstration. The tools are meant to be explored and applied by interested users and to inspire fellow researchers. Too...
