We present work which organises personal digital photo collections based on contextual information, such as time and location, combined with content-based analysis such as face detection and other feature detectors. The MediAssist demonstration system illustrates the results of our research into digital photo management, showing how a combination of automatically extracted context and content-b...

Social Networking Services (SNS) have gained immense popularity in developing countries like India, where digital natives are actively communicating on these platforms. Understanding the interaction between technology systems and digital natives, and proposing guidelines and recommendations for the development of better systems is highly valuable. Prior research examining users’ motivations and...

This paper presents SMIL PhotoShow, an authoring tool for photo books, which allows the creation of enhanced multimedia presentations, enriched with audio (music or spoken) comments, transition effects and animations in a very simple way. Our tool allows to create a digital counterpart of a printed photo book with the aim to bridge the gap between digital web albums and printed photo books. Sin...

This demonstration presents the MediAssist prototype system for organisation of personal digital photo collections based on contextual information, such as time and location of image capture, and content-based analysis, such as face detection and recognition. This metadata is used directly for identification of photos which match specified attributes, and also to create text surrogates for phot...

SMS messaging has traditionally been utilised for person-to-person messaging. Some researchers have recognised the value in using SMS for person-to-location messaging, but such technology has been largely confined to the laboratory. We argue that commercially available digital photo frames provide a low-cost opportunity for situated display technology, and that such technology can be used for p...

Data collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC are used to measure the lifetimes of the B0 and B+ mesons. The data sample consists of 8.3 fb collected near the Υ (4S) resonance. B0 and B+ mesons are fully reconstructed in several exclusive hadronic decay modes to charm and charmonium final states. The B lifetimes are determined from the flight length differenc...

We summarize the results of the New Gauge Boson Subgroup on the physics of extended gauge sectors at future colliders as presented at the 1996 Snowmass workshop. We discuss the direct and indirect search reaches for new gauge bosons at both hadron and lepton colliders as well as the ability of such machines to extract detailed information on the couplings of these particles to the fermions and ...

An intensive in-house effort in the past year has produced coatings and devices that will survive the peak 35 1-nm fluence expected in the OMEGA Upgrade. The stringent ultraviolet requirements for the upgrade stem from the decision to place the frequency-conversion crystals in the laser bay (rather than at the target chamber).l At that time, only one report of satisfactory laser-damage threshol...

A broad class of supersymmetric extensions of the standard model predict a Z 0 vector boson whose mass is naturally in the range 250 GeV<MZ0<2 TeV. To avoid unacceptably large mixing with the Z, one requires either a discrete tuning of the U(1)0 charges or a leptophobic Z 0. Both cases are likely to arise as the low energy limits of heterotic string compacti cations, but a survey of existing re...
