A systematic survey on complex network visualization in industrial manufacturing and production

This paper presents a systematic survey of the visualization and visual analysis of complex networks as generated in studies on industrial manufacturing and production problems. We provide a description and categorization of the types of networks found in this area. We also inves...

On Kotzig's conjecture in random graphs

In 1963, Anton Kotzig famously conjectured that K n , the complete graph of order n , where n is even, can be decomposed into n − 1 perfect matchings such that every pair of these matchings forms a Hamilton cycle. The problem is still wide open and here we consider a variant of i...

Deep learning-based stress detection using multimodal biosignals

Abstract Stress-related health problems drive an urgent need for sensitive, real-time monitoring devices capable of capturing psychophysiological stress dynamics in natural settings. This study presents a stress detection system that uses deep learning, combining synchronized phy...

Hilbert Transform Pairs of Wavelets

ABSTRACT The orthogonal projection of a real orthonormal wavelet basis onto the Hardy space—consisting of functions whose Fourier transform is supported only on the positive real axis—yields a Parseval frame of wavelets. Motivated by practical considerations, Kingsbury proposed t...

Reduced extinction risk for autotrophs in the open ocean

Abstract The marine plankton record offers a unique archive of deep-time ecological and evolutionary dynamics in the open ocean. With distinct biomineral compositions, trophic modes and other diverse ecological and geographic preferences, fossilized marine unicellular plankton gr...
