The information percolator: Ambient information display in a decorative object

by Jeremy M. Heiner, Scott E. Hudson, Kenichiro Tanaka - Proceedings of the ACM Symposium on User Interface Software and Technology (UIST , 1999
"... Most current interface designs require that the user focus their attention on them in order to be of value. However, as the price of computation falls, and computational capabilities make their way into many everyday objects, the demand for attention from many different directions may begin to serio ..."

time. Ambient Displays are designed to work primarily in the periphery of a user’s awareness, moving to the center of attention only when appropriate and desirable. This paper describes a new ambient information display that is designed to give a rich medium of expression placed within an aesthetically

ASTROPHYSICS Dynamical Evolution of High Velocity Clouds in the Intergalactic Medium

by C. Konz, C. Brüns, G. T. Birk , 2002
"... Abstract H I observations of high-velocity clouds (HVCs) indicate, that they are interacting with their ambient medium. Even clouds located in the very outer Galactic halo or the intergalactic space seem to interact with their ambient medium. In this paper, we investigate the dynamical evolution of ..."

Swift GRB Afterglows and the Forward-Shock Model

by A. Panaitescu , 2006
"... The X-ray, optical and radio emission following a Gamma-Ray Burst (GRB) is thought to arise in the interaction between the GRB ejecta and the circumburst medium, which leads to a forward shock energizing the ambient medium ..."

Parametric studies of cosmic ray acceleration in supernova remnants

by D. Kosenko, G. Ferr, A. Decourchelle , 2014
"... We present a library of numerical models of cosmic-ray accelerating supernova remnants (SNRs) evolving through a homogeneous ambient medium. We analyze distributions of the different energy components and diffusive shock acceleration timescales for the models in various conditions. The library compr ..."

The bed: a medium for intimate communication

by Chris Dodge - In Proc. of CHI '07 EA, 371–372 , 2007
"... ABSTRACT In this paper, I present "The Bed", an environment providing a new form of abstracted presence for intimate, non-verbal inter-personal communication. This secure and familiar environment is explored for its ability to become a shared virtual space for bridging the distance betwee ..."

between two remotely located individuals through aural, visual, and tactile manifestations of subtle emotional qualities. As an example, I describe the application of these tangible interfaces and ambient media into a working prototype.

METAL ENRICHMENT OF THE INTRA-CLUSTER MEDIUM: RAM-PRESSURE STRIPPING OF CLUSTER GALAXIES

by W. Domainko, W. Kapferer, S. Schindler, E. V. Kampen, S. Kimeswenger, M. Mair, M. Ruffert , 2004
"... We present numerical simulations of the dynamical and chemical evolution of galaxy clusters. X-ray spectra show that the intra-cluster medium contains a significant amount of metals. As heavy elements are produced in the stars of galaxies material from the galaxies must have been expelled to enrich ..."

the ambient medium. We have performed hydrodynamic simulations investigating various processes. In this presentation we show the feedback from gas which is stripped from galaxies by ram-pressure stripping. The efficiency, resulting spatial distribution of the metals and the time dependency of this enrichment

Dynamical Friction in a Gaseous Medium

by Eve C. Ostriker , 1998
"... Using time-dependent linear perturbation theory, we evaluate the dynamical friction force on a massive perturber Mp traveling at velocity V through a uniform gaseous medium of density ρ0 and sound speed cs. This drag force acts in the direction − ˆ V, and arises from the gravitational attraction be ..."

between the perturber and its wake in the ambient medium. For supersonic motion (M ≡ V/cs> 1), the enhanced-density wake is confined to the Mach cone trailing the perturber; for subsonic motion (M < 1), the wake is confined to a sphere of radius cst centered a distance V t behind the perturber

Do Magnetometers Measure B or H?

by F. J. Lowes , 1973
"... It is shown by simple arguments that real magnetometers, whether scaled in units of B or of H, all have calibrations which depend to some finite extent on the permeability of the ambient medium in which the field is measured. 1. ..."

On the Speed of Astrophysical Jets

by C. Chicone, B. Mashhoon, B. Punsly , 2008
"... The evolution of the speed of astrophysical jets relative to the ambient medium is investigated using a simple model. We assume that a jet clump is under the influence of the relativistic tidal force of the central source as well as the plasma force due to the electromagnetic field of the ambient me ..."
