Robustness analysis of car-following models for full speed range ACC systems. (arXiv:1911.11805v1 [physics.soc-ph])

Adaptive cruise control systems are fundamental components of the automation of the driving. At upper control level, ACC systems are based on car-following models determining the acceleration rate of a vehicle according to the distance gap to the predecessor and the speed difference. The pursuit strategy consists in keeping a constant time gap with the…

Detection of Dynamical Matching in a Caldera Hamiltonian System using Lagrangian Descriptors. (arXiv:1911.11811v1 [nlin.CD])

The goal of this paper is to apply the method of Lagrangian descriptors to reveal the phase space mechanism by which a Caldera-type potential energy surface (PES) exhibits the dynamical matching phenomenon. Using this technique, we can easily establish that the non-existence of dynamical matching is a consequence of heteroclinic connections between the unstable manifolds…

Scalable additive manufacturing via integral image formation. (arXiv:1911.11817v1 [physics.app-ph])

Additive manufacturing techniques enable the fabrication of functional microstructures with mechanical and chemical properties tailored to their intended use. One common technique is stereolithography, which has recently been augmented in response to modern demands to support smaller features, larger build areas, and/or faster speeds. However, a limitation is that such systems typically utilize a single-aperture…

Noise Robust Generative Adversarial Networks. (arXiv:1911.11776v1 [cs.CV])

Generative adversarial networks (GANs) are neural networks that learn data distributions through adversarial training. In intensive studies, recent GANs have shown promising results for reproducing training data. However, in spite of noise, they reproduce data with fidelity. As an alternative, we propose a novel family of GANs called noise-robust GANs (NR-GANs), which can learn a…

Supervised load identification of 18 fixed-speed motors based on their turn-on transient current. (arXiv:1911.11797v1 [eess.SP])

Several studies have already shown that the transient current can be successfully used to identify electric loads. However, most of the proposed methods were validated using only a handful of loads whose electric properties often differed significantly from each other. Therefore, a much more challenging empirical study was carried out here using 18 different fixed-speed…

Multi-Object Portion Tracking in 4D Fluorescence Microscopy Imagery with Deep Feature Maps. (arXiv:1911.11808v1 [eess.IV])

3D fluorescence microscopy of living organisms has increasingly become an essential and powerful tool in biomedical research and diagnosis. An exploding amount of imaging data has been collected, whereas efficient and effective computational tools to extract information from them are still lagging behind. This is largely due to the challenges in analyzing biological data. Interesting…

Autonomous WiFi Fingerprinting for Indoor Localization. (arXiv:1911.11825v1 [eess.SP])

WiFi-based indoor localization has received extensive attentions from both academia and industry. However, the overhead of constructing and maintaining the WiFi fingerprint map remains a bottleneck for the wide-deployment of WiFi-based indoor localization systems. Recently, robots are adopted as the professional surveyor to fingerprint the environment autonomously. But the time and energy cost still limit…

The Effect of Salt Shock on Growth and Pigment Accumulation of Dunaliella Salina. (arXiv:1911.11840v1 [q-bio.QM])

Dunaliella Salina is a halotolerant microalga with great pharmaceutical and industrial potential, which commonly exists in hypersaline environments. Moreover, it is the best commercial source of beta-carotene (which has high anti-oxidant properties) in comparison to other microalgae. In this study, we investigated growth and accumulations of chlorophyll a and b, beta-carotene, and carotenoid after salt…

Physics Approaches to the Spatial Distribution of Immune Cells in Tumors. (arXiv:1911.11846v1 [physics.bio-ph])

The goal of immunotherapy is to enhance the ability of the immune system to kill cancer cells. Immunotherapy is more effective and, in general, the prognosis is better, when more immune cells infiltrate the tumor. We explore the question of whether the spatial distribution rather than just the density of immune cells in the tumor…

Formation of a hard surface layer during drying of a heated porous media. (arXiv:1911.11857v1 [cond-mat.soft])

We report surface hardening or crust formation, unlike caking, during drying when a confined porous medium was heated from above using IR radiation. These crusts have higher strength than their closest counterparts such as sandcastles and mud-peels which essentially are clusters of partially wet porous medium. Observed higher strength of the crusts is mostly due…
