Evaluation of Fermi Read-out of the ATLAS Tilecal Prototype

Prototypes of the \fermi{} system have been used to read out a prototype of the \atlas{} hadron calorimeter in a beam test at the CERN SPS. The \fermi{} read-out system, using a compressor and a 40 MHz sampling ADC, is compared to a standard charge integrating read-out by measuring the energy resolution of the calorimeter separately with the two systems on the same events. Signal processing techniques have been designed to optimize the treatment of \fermi{} data. The resulting energy resolution is better than the one obtained with the standard read-out

THE DEVELOPMENT OF GRAIN-STRUCTURE DURING GROWTH OF METALLIC-FILMS

The mechanisms that have been proposed to govern the grain structure of vapor deposited metallic films are reviewed, and some problems in these theories discussed. A new phenomenological description of grain growth based on the concept of the variation in mobility of individual grain boundaries allows three characteristic regimes of growth to be distinguished. Detailed observations on the grain structure of both thick and thinner metal films have been made to clarify the variation of grain size and morphology with substrate temperature. The new model for grain growth allied with surface diffusion mechanisms can explain in a consistent manner the experimentally observed grain structures. © 1984

Browsing the Real World using Organic Electronics, Si-Chips, and a Human Touch.

Organic electronics have been developed according to an orthodox doctrine advocating "all-printed, "all-organic and "ultra-low-cost primarily targeting various e-paper applications. In order to harvest from the great opportunities afforded with organic electronics potentially operating as communication and sensor outposts within existing and future complex communication infrastructures, high-quality computing and communication protocols must be integrated with the organic electronics. Here, we debate and scrutinize the twinning of the signal-processing capability of traditional integrated silicon chips with organic electronics and sensors, and to use our body as a natural local network with our bare hand as the browser of the physical world. The resulting platform provides a body network, i.e., a personalized web, composed of e-label sensors, bioelectronics, and mobile devices that together make it possible to monitor and record both our ambience and health-status parameters, supported by the ubiquitous mobile network and the resources of the "cloud".Funding agencies:  Knut and Alice Wallenberg Foundation; Onnesjo Foundation; VINNOVA; Swedish Foundation for Strategic Research</p
