Anomaly Detection in Surveillance Videos by Future Appearance-motion Prediction

Tuan-Hung Vu, Sebastien Ambellouis, Jacques Boonaert, Abdelmalik Taleb-Ahmed

Anomaly detection in surveillance videos is the identification of rare events which produce different features from normal events. In this paper, we present a survey about the progress of anomaly detection techniques and introduce our proposed framework to tackle this very challenging objective.…

Measurement-based feasibility exploration on detecting and localizing multiple humans using MIMO radio channel properties

Yang Miao, Emmeric Tanghe, Jun-Ichi Takada, Troels Pedersen, Pierre Laly, Davy Gaillot, Martine Lienard, Luc Martens, Wout Joseph

This paper explores the feasibility of using the multiple-input multiple-output (MIMO) radio channel properties to passively detect and localize multiple humans in indoor environments. We propose to utilize the unique reverberation characteristics of indoor channels for the purpose of detecting,…

Continuous-wave lines up to 5.5 THz from the ammonia laser pumped by a quantum cascade laser

Jean-Francois Lampin, M.-H. Mammez, Z. Buchanan, M. Micica, O. Pirali, M.-A. Martin-Drumel, Sophie Eliet, S Barbieri, Francis Hindle, P. Roy, Gaël Mouret

We have recently demonstrated a continuous wave molecular laser emission based on ammonia optically pumped by a quantum cascade laser. We report here new results obtained with an optimized laser prototype pumped by a tunable external cavity quantum cascade laser. New laser lines with high output…

Probing nanoparticle-membrane interactions by combining amphiphilic diblock copolymer assembly and plasmonics

Amelie H. R. Koch, Svenja Morsbach, Tristan Bereau, Gaëtan Lévêque, Hans-Juergen Butt, Markus Deserno, Katharina Landfester, George Fytas

Understanding the interactions between nanoparticles (NPs) and boundaries of cells is crucial both for their toxicity and therapeutic applications. Besides specific receptor-mediated endocytosis of surface-functionalized NPs, passive internalization is prompted by relatively unspecific parameters,…

Massive radio channel sounder architecture for 5G mobility scenarios: MaMIMOSA

Pierre Laly, Davy Gaillot, Gauthier Delbarre, M. van den Bossche, G. Vermeeren, F. Challita, E. Tanghe, Eric Pierre Simon, W. Joseph, L. Martens, M. Lienard

This paper presents a real-time 64 x 16 massive MIMO channel sounder based on space-frequency division multiplexing and antenna subarray switching, giving a large possibility of antenna allocation and frequency tone between 2 and 12 GHz. This channel sounder called Massive MIMOSA or MaMIMOSA…

Friction-induced energy losses in mechanical contacts subject to random vibrations

Vladislav Aleshin, Antonio Papangelo

In this paper, we apply the previously developed Method of Memory Diagrams (MMD) to the description of an axisymmetric mechanical contact with friction subject to random vibrations. The MMD belongs to a family of semi-analytical methods of contact mechanics originating from the classical Cattaneo-…

AOTF-based hyperspectral imaging phase microscopy

Konstantin B. Yushkov, Justine Champagne, Jean-Claude Kastelik, Oleg Yu. Makarov, Vladimir Ya. Molchanov

Phase imaging microscopy with incoherent object illumination is convenient and affordable for biomedical research and clinics since it provides easy integration with a variety of bright-field optical microscopes. We report the design of a new hyperspectral imaging system based on a combination of a…

Experimental Characterization of A Piezoelectric Transducer Array Taking into Account Crosstalk Phenomenon

Abdelmajid Bybi, Driss Khouili, Christian Granger, Mohammed Garoum, Ahmed Mzerd, Anne-Christine Hladky

Ultrasonic transducer arrays are generally composed of several piezoelectric elements arranged in 1D or 2D ways. Crosstalk is an undesirable phenomenon decreasing the performance of these devices. It generates parasitic displacements at the elements' radiating surfaces, which changes the…

Tunable frequency band structure in photo-responsive elastic metamaterials

A.S. S Gliozzi, M. Miniaci, A. Chiappone, A. Bergamini, F. Bosia, E. Descrovil, E Descrovi

An important issue in the field of elastic metamaterials is that their dynamic properties, such as the band gap frequencies, are typically fixed once the structure has been designed and fabricated. To overcome this limitation, many efforts have been made to conceive materials with adaptive elastic…
