Algorithmic random number generators require recurring sequences with very long periods and good multivariate uniformity properties. Point sets and sequences for quasi-Monte Carlo numerical integration need similar multivariate uniformity properties as well. It then comes as no surprise that both types of applications share common (or similar) construction methods. However, there are some diffe...

We show a link between two apparently unrelated areas, namely uniformity and minimum aberration, both of which have been of substantial recent interest. Speciically, with reference to regular fractions of two-level factorials, we derive an expression for the centered L 2-discrepancy measure for uniformity in terms of the wordlength pattern. This result indicates, in particular, an excellent beh...

Light-guide plates (LGPs) with aperiodic or size-varied microstructures are widely used in edge-lit light-source backlight systems for their high uniformity. In this Letter we designed a LGP with periodic and single-sized microstructures and analyzed the relationship between the holistic arrangement density of the microstructures and the uniformity. By controlling the holistic arrangement densi...

A photomultiplier setup for precise relative CsI(Tl) crystal light yield and uniformity measurements is described. It is used for wrapping material studies to optimize the uniformity and the yield of the light output of 36 cm long crystals. The uniformity is an important property in high energy photon calorimetry. Results of an optimization of photodiode coupling to crystals, the influence of t...

In this paper, we have compared r.e. sets based on their enumeration orders with Turing machines. Accordingly, we have defined novel concept “uniformity” for Turing machines and r.e. sets and have studied some relationships between “uniformity” and both onereducibility and Turing reducibility. Furthermore, we have defined “type-2 uniformity” concept and studied r.e. sets and Turing machines bas...

Print quality demands for coated papers are steadily growing, and achieving coating uniformity is crucial for high image sharpness, colour fidelity, and print uniformity. Coating uniformity may be divided into two scales: coating thickness uniformity and coating microstructure uniformity, the latter of which includes pigment, pore and binder distributions within the coating layer. This thesis c...

Infrared focal plane arrays (IRFPA) imaging systems are strongly affected by the spatial non-uniformity of the IRFPA response. The non-uniformity is due to the pixel-to-pixel responsivity (gain) and dark current (offset) variations of the IRFPA. The non-uniformity results in a fixed spatial noise superimposed on the infrared image, which can completely mask the useful thermal signatures in an i...
