Visualization of Radiative Shock Waves Using CCD Camera Systems

Shock Waves for Radiative Hyperbolic–elliptic Systems

The present paper deals with the following hyperbolic–elliptic coupled system, modelling dynamics of a gas in presence of radiation, ( ut + f(u)x + Lqx = 0 −qxx +Rq +G · ux = 0, x ∈ R, t > 0, where u ∈ R, q ∈ R and R > 0, G, L ∈ R. The flux function f : R → R is smooth and such that ∇f has n distinct real eigenvalues for any u. The problem of existence of admissible radiative shock wave is cons...

The Structure of Radiative Shock Waves

The structure of steady plane-parallel radiative shock waves propagating through the hydrogen gas undergoing partial ionization and excitation of bound atomic states is investigated in terms of the self-consistent solution of the equations of fluid dynamics, radiation transfer and atomic kinetics. The shock wave model is represented by a flat finite slab with no incoming radiation from external...

Intelligent Surveillance Using an Omnidirectional CCD Camera

Video surveillance, object tracking and activity monitoring are some of the important issues for a homecare robotic system. In this work, an omnidirectional video camera is adopted to provide a 360 degree view angle of the indoor scene in a single image. Some basic functions for smart living and elderly care, such as motion detection, object tracking and target behavior analysis, are implemente...

Kinetic PCR Analysis Using a CCD-camera

CCD Camera Gain Measurement

The gain of a CCD camera is the conversion between the number of electrons ("e-") recorded by the CCD and the number of digital units ("counts") contained in the CCD image. It is useful to know this conversion for evaluating the performance of the CCD camera. Since quantities in the CCD image can only be measured in units of counts, knowing the gain permits the calculation of quantities such as...
