An algorithm is proposed to detect community structures in social networks. The algorithm begins with a community division based on prior knowledge of the degrees of the nodes and then combines the communities until a clear partition is obtained. In applications such as a computer-generated network, Ucinet networks, and Chinese rural-urban migrants’ social networks, the algorithm can achieve hi...

We study aspects of the combinatorial and graphical structure shared by a certain family of recursively generated arrays related to the operation of Nimaddition. In particular, these arrays display periodic behavior along rows and diagonals. We explain how various features of computer-generated graphics depicting these arrays are reflections of the theorems we prove.

Computer applications in the field of psychological test administration have significant ethical implications for clinicians, client/responders, and computerized test construction and administration. Lack of awareness of computer-related issues may undermine clinicians' ability to ethically perform computerized psychological assessments. Graduate training in computerized testing is limited, and...

Computer-generated designs in the sphere are described which have the minimal (or larger) number of runs for a full quadratic response-surface design. In the case of 3 factors, the designs have 10 through 33 runs; for 4 factors, 15 through 28 runs; for 5 factors, 21 through 33 runs; etc. Some of these designs are listed here in full; the others can be obtained from the authors. The designs were...

1 We present a method to analytically compute the light distribution of triangles directly in frequency space. This allows for fast evaluation, shading and propagation of light from 3D mesh objects using angular spectrum methods. The algorithm complexity is only dependant on the hologram resolution and the polygon count of the 3D model. In contrast to other polygon based computer generated holo...

Laguerre–Gaussian beams are structured light with a donut-shaped symmetric intensity profile and helical phase profile. The beam is defined by quantized parameter known as the mode number which extends to infinity. availability of unbounded modes makes these promising candidate for next-generation optical computing, communication technologies. can be made asymmetric through certain techniques t...

Deep learning offers a novel opportunity to achieve both high-quality and high-speed computer-generated holography (CGH). Current data-driven deep algorithms face the challenge that labeled training datasets limit performance generalization. The model-driven introduces diffraction model into neural network. It eliminates need for dataset has been extensively applied hologram generation. However...

The computer revolution has been going on long enough now that no one attending these meetings would be surprised to hear a discussion of any one of several forms of computer-generated "reality." A few years ago the phrase was walk-through or fly-by for a computer-simulated journey through space. Today the phrase is virtual reality a term which conjures up thoughts of versions of reality whethe...

We give a conjecture for the expected value of the optimal kassignment in an m × n-matrix, where the entries are all exp(1)-distributed random variables or zeros. We prove this conjecture in the case there is a zerocost k − 1-assignment. Assuming our conjecture, we determine some limits, as k = m = n → ∞, of the expected cost of an optimal n-assignment in an n by n matrix with zeros in some reg...
