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

The “Care Delivery Frame (CDF)” presented here integrates two distinctly different applications, the home telehealth system and the remote photo sharing service of digital photo frame, to create a unique information channel for senior users who are not familiar with the operation of computers and Internet. In addition to health data monitoring, children or caregivers can “deliver care” to their...

We present and describe a catalog of galaxy photometric redshifts (photo-z’s) for the Sloan Digital Sky Survey (SDSS) Data Release 6 (DR6). We use the Artificial Neural Network (ANN) technique to calculate photo-z’s and the Nearest Neighbor Error (NNE) method to estimate photo-z errors for ∼ 77 million objects classified as galaxies in DR6 with r < 22. The photo-z and photo-z error estimators a...

In this paper a new approach for matching aspect ratio of a digital photo for borderless printing by complementing it with fragments extracted from the same photo is proposed. This approach comprises analysis of side strips of the source photo in order to estimate the possibility to complement it without visible artifacts; complementing one or both opposite sides of the photo, matching the desi...

The Photo Response Non-Uniformity acts as a digital fingerprint that can be used to identify image sensors. This characteristic has been used in previous research to identify scanners, digital photo cameras and digital video cameras. In this paper we use a wavelet filter from Lukáš et al [1] to extract the PRNU patterns from multiply compressed low resolution video files originating from webcam...

Kodak’s Photo CD system, originally intended for consumer applications, has been used successfully by museums and libraries to store digital images from scanned film, prints and documents. With recent advances in digital image standards and their anticipated adoption by cultural institutions, questions arise as to how best to convert Photo CD image files. We describe both the file format and co...

The concept design of a recollection supporting device is implemented as a portable Photo Browser using souvenirs as a graspable user interface. When brought into an intelligent room, the Photo Browser is able to recognize the presence of people, graspable objects, and available output devices. The ability of souvenirs to trigger recollections is used as a shortcut to (sub-) sets of photos. Thi...

Digital images are generated by different sensors, understanding which kind of sensor has acquired a certain image could be crucial in many application scenarios where digital forensic techniques operate. In this paper a new methodology which permits to establish if a digital photo has been taken by a photo-camera or has been scanned by a scanner is presented. The specific geometrical features ...
