We describe initial work on a system for augmenting video sequences with 3-D graphics so that they appear to be present within the scene. Our aim is to do this in realtime for sequences captured by uncalibrated ‘live’ cameras, such as a hand-held or wearable. The paper focuses on obtaining 3-D camera motion and depth estimates for these types of sequences using sparse feature tracking and the r...

In many potential applications of machine learning, unlabelled data are abundantly available at low cost, but there is a paucity of labelled data, and labeling unlabelled examples is expensive and/or time-consuming. This motivates the development of active learning methods, that seek to direct the collection of labelled examples such that the greatest performance gains can be achieved using the...

Selection is a common task in Virtual Environment (VE) interfaces. Several techniques have been created to perform the task and two testbed studies have performed comparison studies between the techniques. In this study focusing on Raycasting selection, we created an understanding of the known factors influencing selection and create a model of selection time and angular error. We found evidenc...

Pain is a physiological and adaptive process which occurs to protect organisms from tissue damage and extended injury. Pain sensation beyond injury, however, is a pathological process which is poorly understood. Experimental models of neuropathic pain demonstrate that reactive astrocytes contribute to reduced nociceptive thresholds. Astrocytes release "gliotransmitters" such as D-serine, glutam...

The disproportionately higher rate of hypertension (HTN) and related cardiovascular morbidity of Blacks compared with Whites is well-documented.1 Improvements in blood pressure (BP) control can result in significant reduction in cardiovascular disease risk.2 Adopting therapeutic lifestyle changes (TLC) such as increasing intake of fruits, vegetables, and low fat dairy foods, decreasing intake o...

Objectives: To present the methods and baseline characteristics of the Pietà study, a population-based survey investigating successful brain aging in the oldest-old. Method: The study was conducted in Caeté (MG), Brazil. In 2007, 1,251 individuals aged 75+ years were living in the city and were invited to participate. Participants responded to a general health questionnaire and were submitted t...

This paper presents the recent results from Super-Kamiokande atmospheric neutri-nos and from K2K accelerator neutrinos. Both results show the signal of neutrino oscillation, and provide new and precise information of oscillation parameters. The oscillation parameters are constraint to be between 1.5×10 −3 eV 2 and 3.9×10 −3 eV 2 for ∆m 2 and to be greater than 0.92 for sin 2 2θ.

Evidences for neutrino oscillations coming from atmospheric and solar observations can be probed by terrestrial long baseline experiments. This requires accelerator beams or nuclear power plants. The current status of these searches as well as future activities are discussed. A precise determination of all matrix elements and searches for a leptonic CP-violation will be possible with high inten...

The application of optimization tools and techniques to operate the reservoir on a Multi-objective basis under the circumstances of climate change is unavoidable. The present study utilizes the Multi-Objective Farmland Fertility Optimization (MOFFA) algorithm to derive optimum rules on the operation of the Golestan Dam in Golestan province under circumstances of climate change. The two targets ...
