Component based software development is prone to unexpected interaction faults. The goal is to test as many potential interactions as is feasible within time and budget constraints. Two combinatorial objects, the orthogonal array and the covering array, can be used to generate test suites that provide a guarantee for coverage of all -sets of component interactions in the case when the testing o...

The problems we study in this thesis arise in computer science, extremal set theory and quantum computing. The first common feature of these problems is that each can be reduced to characterizing the independent sets of maximum size in a suitable graph. A second common feature is that the size of these independent sets meets an eigenvalue bound due to Delsarte and Hoffman. Thirdly, the graphs t...

We demonstrate an ultra-compact, broadband on-chip near-infrared (NIR) spectroscopy system based on a narrow-band plasmonic filter array. The entire filter array, consisting of 28 individual subwavelength metallic gratings, was monolithically integrated in a thin gold film on a quartz substrate, covering a 270 nm spectra from 1510 nm to 1780 nm. In order to achieve a high spectral resolution, e...

There are many results about generating pair-wise covering arrays with strength τ=2 have been reported, but fewer results are published for high-strength covering arrays with a higher-strength τ>2. In configuration testing of sensor networks, high-strength covering array is required to construct combinatorial test cases. To generate combinatorial test suite with higher-strength, a backtracking ...

We present a new concept for c-ray detector arrays. An example, called GRETA (Gamma-Ray Energy Tracking Array), consists of highly segmented HPGe detectors covering 4p solid angle. The new feature is the ability to track the scattering sequence of incident c-rays and in every event, this potentially allows one to measure with high resolution the energy deposited, the location (incident angle) a...

combination of a small surface coil with three dielectric discs (B) and an array with three surface coils (C), all covering the same portion of the object. Top view of the coil conductors (orange) is shown on the first row. Dielectric discs are depicted in blue, whereas the gray circle indicates a transverse section of the phantom through the center of the coil/array. The length of the phantom ...

KASCADE-Grande is an extensive air shower experiment at Forschungszentrum Karlsruhe, Germany. Main parts of the experiment are the Grande array spread over an area of 700 × 700m , the original KASCADE array covering 200 × 200m with unshielded and shielded detectors, and additional muon tracking devices. This multi-detector system allows to investigate the energy spectrum, composition, and aniso...

This article is a guideline covering a wide array of cervical conditions seen in the workers' compensation, as well as the nonworkers' compensation, population. The guideline is intended to provide a diagnostic and treatment algorithm to commonly seen cervical conditions such as single-level and multilevel radiculopathies and myelopathies.

A method is presented for reconstructing images of fast neural evoked activity in rat cerebral cortex recorded with electrical impedance tomography (EIT) and a 6 × 5 mm(2) epicortical planar 30 electrode array. A finite element model of the rat brain and inverse solution with Tikhonov regularization were optimized in order to improve spatial resolution and accuracy. The optimized FEM mesh had 7...

In order to test the design of the Pierre Auger Observatory, as well as different construction alternatives, a small subset of the full array is being built in Malargüe, Argentina, and will be put into operation this year. It will consist of 40 surface detectors, covering an area of 46 km, and 2 fluorescence telescopes with an angle of view of 30◦ x 30◦ each. We present a description of this en...
