Yang, Yang (author), Zhou, Jie (author), Ai, Jiangbo (author), Bin, Yi (author), Hanjalic, A. (author), Shen, Heng Tao (author)In this paper, we propose a novel approach to video captioning based on adversarial learning and long short-term memory (LSTM). With this solution concept, we aim at compensating for the deficiencies of LSTM-based video captioning methods that generally show potential to effectively handle temporal nature of video data when generating...journal article 2018

Liao, J. (author), Shen, Shuheng (author), Eisemann, E. (author)We present a novel pipeline to generate a depth map from a single image that can be used as input for a variety of artistic depth-based effects. In such a context, the depth maps do not have to be perfect but are rather designed with respect to a desired result. Consequently, our solution centers around user interaction and relies on a scribble...journal article 2018

Qin, Z. (author), Shen, Yanfeng (author), Loh, Poh Chiang (author), Wang, Huai (author), Blaabjerg, Frede (author)A Dual Active Bridge (DAB) converter can achieve a wide high-efficiency range when its input and output voltages are equal, assuming a 1:1 turns ratio for its isolation transformer. If its input or output voltage is doubled, efficiency of the DAB will drop significantly, because of the introduction of hard switching and high circulating power....journal article 2018

Shen, Y. (author), Wang, Jinguo (author), Lindenbergh, R.C. (author), Hofland, Bas (author), Ferreira, Vagner G. (author)The use of a terrestrial laser scanner is examined to measure the changes of rock slopes subject to a wave attack test. Real scenarios are simulated in a water flume facility using a wave attack experiment representing a storm of 3000 waves. The stability of two rock slopes of different steepness was evaluated under the set conditions. For...journal article 2018

(author), Wang, Guanzhong (author), Xu, D. (author), Bouman, D. (author), Geresdi, A. (author), Bakkers, E.P.A.M. (author), Kouwenhoven, Leo P. (author)The number of electrons in small metallic or semiconducting islands is quantised. When tunnelling is enabled via opaque barriers this number can change by an integer. In superconductors the addition is in units of two electron charges (2e), reflecting that the Cooper pair condensate must have an even parity. This ground state (GS) is...journal article 2018

Shen, K. (author), Bauer, G.E. (author)We develop a theory of spin wave dynamics excited by ultrafast focused laser pulses in a magnetic film. We take into account both the volume and surface spin wave modes in the presence of applied, dipolar and magnetic anisotropy fields and include the dependence on laser spot exposure size and magnetic damping. We show that the sound waves...journal article 2018

(author)Low dimensional semiconducting structures with strong spin-orbit interaction (SOI) and induced superconductivity attracted great interest in the search for topological superconductors. Both the strong SOI and hard superconducting gap are directly related to the topological protection of the predicted Majorana bound states. Here we explore the...journal article 2018

(author), Kirilyuk, Andrei (author), Rasing, Theo (author), Saitoh, Eiji (author)To know the properties of a particle or a wave, one should measure how its energy changes with its momentum. The relation between them is called the dispersion relation, which encodes essential information of the kinetics. In a magnet, the wave motion of atomic spins serves as an elementary excitation, called a spin wave, and behaves like a...journal article 2017

(author)We theoretically study the effects of strong magnetoelastic coupling on the transport properties of magnetic insulators. We develop a Boltzmann transport theory for the mixed magnon-phonon modes ("magnon polarons") and determine transport coefficients and the spin diffusion length. Magnon-polaron formation causes anomalous features in the...journal article 2017

Shen, Y. (author), Lindenbergh, R.C. (author), Wang, J. (author)A method is introduced for detecting changes from point clouds that avoids registration. For many applications, changes are detected between two scans of the same scene obtained at different times. Traditionally, these scans are aligned to a common coordinate system having the disadvantage that this registration step introduces additional...journal article 2017

(author), Saitoh, Eiji (author)Sharp structures in the magnetic field-dependent spin Seebeck effect (SSE) voltages of Pt/Y3Fe5O12 at low temperatures are attributed to the magnon-phonon interaction. Experimental results are well reproduced by a Boltzmann theory that includes magnetoelastic coupling. The SSE anomalies coincide with magnetic fields tuned to the threshold of...journal article 2016
