Rhythmic Gait Signature from Video without Motion Capture

Presented at the 16th International Conference on Auditory Display (ICAD2010) on June 9-15, 2010 in Washington, DC.The goal of gait biometrics is usually to identify individual people from a distance, often without their knowledge. As such, gait biometrics provide a source of data that ties a visible pattern of motion to an individual. We describe our work to convert one particular biometric gait signature into a rhythmic sound pattern that is unique for different individuals. We begin with a camera viewing a person walking on a treadmill, then extract a phase configuration that describes the timing pattern of motions in the gait. The timing pattern is then converted to a rhythmic percussion pattern that allows one to hear differences and similarities across a population of gaits. We can also hear phase patterns in a gait independent of the actual frequency of the gait. Our approach avoids the inconvenience and cost of traditional motion capture methods. We demonstrate our system with the sonification of 25 gaits from the CMU Motion of Body databas

Trends in the incidence of primary liver cancer in Central Uganda, 1960–1980 and 1991–2005

Primary liver cancer (PLC) incidence trends from Africa are unknown. Using Kampala Cancer Registry data from 1960 to 1980 and 1991 to 2005, we identified 771 PLCs. Although rates were stable among men, PLC incidence among women increased >50%. Investigations of viral hepatitis, aflatoxin, obesity, and human immunodeficiency virus (HIV) may help to explain the increasing incidence of hepatocellular carcinomas (HCCs)

Analysis of Implicit Type of a Generalized Fractional Differential Equations with Nonlinear Integral Boundary Conditions

The given paper describes the implicit fractional differential equation with nonlinear integral boundary conditions in the frame of Caputo-Katugampola fractional derivative. We obtain an analogous integral equation of the given problem and prove the existence and uniqueness results of such a problem using the Banach and Krasnoselskii fixed point theorems. To show the effectiveness of the acquired results, convenient examples are presented

Implicit Fractional Differential Equation with Nonlocal Integral-multipoint Boundary Conditions in the Frame of Hilfer Fractional Derivative

This article deals with a nonlinear implicit fractional differential equation with nonlocal integral-multipoint boundary conditions in the frame of Hilfer fractional derivative. The existence and uniqueness results are obtained by using the fixed point theorems of Krasnoselskii and Banach. Further, to demonstrate the effectiveness of the main results, suitable examples are granted
