Observing physical activity in suburbs

Health & Place, 2008
This study examined the reliability of the block walk method (BWM) for observing physical activity on suburban sidewalks/streets. Trained observers simultaneously walked 40 sidewalk/street segments each 1525 m in length at a pace of 30.5 m/min while recording the number of individuals walking/bicycling/jogging and the address where the activity ...

Observational particle physics

Nuclear Physics A, 1988
Abstract A review is given of the detection of neutrinos from the supernova SN1987a and of neutrinos from the sun. Searches for monopoles, dark matter candidates and supersymmetric particles are described, and an outlook on future experiments given.

Ubicon: Observing Physical and Social Activities

2012 IEEE International Conference on Green Computing and Communications, 2012
The connection of ubiquitous and social computing is an emerging research area which is combining two prominent areas of computer science. In this paper, we tackle this topic from different angles: We describe data mining methods for ubiquitous and social data, specifically focusing on physical and social activities, and provide exemplary analysis ...

From Observations to Physical Parameters

2012
Observational measures of AGNs allow us to directly infer some basic physical properties of quasars including (1) physical conditions and chemical abundances in the broad-line emitting gas as well as (2) radius of the line-emitting region, (3) black hole mass, (4) and Eddington ratio.

Physical Observables as Operators

2019
The correspondence of physical observables to operators is established. The fundamental Commutation Relations are discussed. The Expectation Values of physical observables and the concept of Uncertainty are analyzed. The Heisenberg inequality for position and momentum is derived. Hermitian Conjugation and Hermitian operators are introduced.

Deriving Physical Diagnostics from Observations

2009
We review in this course diagnostics for the physical conditions in the atomic component of the flow (electronic densities ne, electronic temperatures T e and hydrogen ionization fraction x e ) based on the most prominent optical and near-infrared forbidden emission lines.
