To define altered metabolites in the brain of patients with probable Alzheimer disease (AD) of two brain regions, localized in vivo hydrogen-1 magnetic resonance (MR) spectroscopy was performed with a short echo time (30 msec) in 11 elderly patients and 10 healthy age-matched subjects. The patients had mild to moderate dementia, assessed with standard(More)
In this paper, current applications of wearable computers are reviewed and categorized according to dimensions of " time " and " reference. " The time dimension is based on whether the system uses information that is stored, information that is current, or information that can help in predicting future events. The reference dimension is concerned with the(More)
A new method for the compression of angiogram video sequences is presented. The method is based on the philosophy that diagnostically significant areas of the image should be allocated the greatest proportion of the total allocated bit budget. The approach uses a three-dimensional wavelet-coder based on the popular set partitioning in hierarchical trees(More)
This paper describes a multistage perceptual quality assessment (MPQA) model for compressed images. The motivation for the development of a perceptual quality assessment is to measure (in)visible differences between original and processed images. The MPQA produces visible distortion maps and quantitative error measures informed by considerations of the(More)
In this paper we discuss the characteristics of pipeline features, e.g. welds, cracks and erosion objects, and present a method for the diagnostically lossless compression of Transverse Field Inspection (TFI) data, a new type of pipeline inspection data in contrast to the traditional Magnetic Flux Leakage (MFL) inspection data.
OBJECTIVE To compare 16 weeks of isometric versus dynamic resistance training versus a control on knee pain and functioning among patients with knee osteoarthritis (OA). DESIGN Randomized clinical trial. SETTING Outpatient setting. PARTICIPANTS A total of 102 volunteer subjects with OA of the knee randomized to isometric (n=32) and dynamic (n=35)(More)
This paper presents a user-centered mobile health device to help people with life-threatening allergies request emergency services in the case of an anaphylactic attack. The device was designed as a support tool to directly assist anaphylactic people and their carers, as opposed to a medical resource designed for practitioners. It makes use of multimedia(More)
This paper presents the digital imaging results of a collaborative research project working toward the generation of an on-line interactive digital image database of signs from ancient cuneiform tablets. An important aim of this project is the application of forensic analysis to the cuneiform symbols to identify scribal hands. Cuneiform tablets are amongst(More)
