The measured detection signals are over 300 times more intense than the light intensity detected by the simultaneous free-space detection method – mainly due to proximity.
Given the sparse nature of the TB data on the homeless, limited number of outbreaks (as defined by the SFDPH TBCP) in the data, and nearly similar detection sensitivity measures obtained using the two spatial resolutions in the previous section, we next set out to examine the performance of the space-time detection method (previously described) to TB data infused with simulated outbreaks.
The quality of spatial data is also important to consider prior to the application of space or space-time cluster detection methods [ 17].
Surveillance, or the systematic routine collection and analysis of health outcome data for disease prevention and control purposes (Thacker and Berkelman 1992), can be applied to the problem of disease clusters through the use of space, time, and space-time pattern detection methods (Kulldorff et al. 1997; Kulldorff 1997, 2001; Rogerson 1997, 2001; Rushton et al. 1996).
To analyse the quantity of space debris and micrometeoroids in space, an innovative in-situ impact detection method has been developed at DLR German Aerospace Centerr) in Bremen, Germany.
To validate the proposed damage detection method state-space equations are derived without external excitation input and experimental tests are carried out.
A light section smoke detection method with three space-protected area was suggested and discussed.
Song and Lyu [17] propose an HT-based segment detection method which utilizes both the parameter space and the image space.
However, inherent characteristics of abattoir condemnation data can bias results from space-time cluster detection methods for disease surveillance, and may need to be accounted for using various adjustment methods.
Previous studies by Alton et al. and Thomas et al. found that various seasonal, secular, disease and abattoir characteristic factors were associated with condemnation rates in Ontario provincial abattoirs; they stressed that these might be accounted for in the application of quantitative space-time cluster detection methods for disease surveillance involving abattoir data [ 17- 19].
The ability of the detection method SOLID for impact detection of space debris and micrometeoroids was clearly demonstrated.
