Studies two different table-based approaches for the calibration of electronic imaging systems. The first approach, which is the classical one, uses the device-independent CIE-XYZ colorimetric space as an intermediate standard space. Input and output devic ...
In oversampled analog-to-digital conversion, the usual reconstruction method using lowpass filtering leads to a mean squared error (MSE) inversely proportional to the oversampling ratio R. The authors prove, under certain assumptions and with periodic anal ...
We present a study of the electronic properties of In(x)Ga1-xAs/GaAs quantum wells when grown on vicinal substrates, based on photoluminescence (PL) and PL excitation experiments under high magnetic field. The samples measured have a wide range of In conte ...
The influence of static disorder on the optical properties of microcavity-embedded quantum wells is studied by means of a microscopic model. Both the exciton-photon coupling and the exciton-disorder interaction are treated nonperturbatively. Despite the no ...
From lidar signals detected with a shot/shot differential absorption lidar instrument tuned for tropospheric O3 measurements and recording each individual return, histograms of their sampled values for each channel of their digitizers were reconstructed. A ...
The contribution of domain walls to the dielectric permittivity of ferroelectrics is customarily explained by the model of locally pinned walls. Here we analyze the complementary case and calculate wall contribution to permittivity of a sample in which 180 ...
We present an experimental study of the exciton and phonon replica dynamics in high quality GaN epilayers and AlGaN/GaN quantum wells (QW) by means of picosecond time-resolved photoluminescence (PL) measurements. A non-exponential decay is observed both at ...
The authors state and prove a theorem solving the problem of commutativity in two dimensions. It is shown under which conditions upsampling and downsampling can be interchanged in two dimensions. This is the generalization to arbitrary two-dimensional latt ...
