November 8: Seminar by Arindam Mishra - India

Scientific seminar by Arindam Mishra from India.
Title: Extreme events in a network of heterogeneous Josephson junctions.
Seminar will be held in the Seminar Room near Dean's Office in A22 building at 11.00.

Abstract: We observe rare and recurrent large spiking events in a heterogeneous network of superconducting Josephson junctions (JJ) connected through a resistive load and driven by a radio-frequency (rf) current in addition to a constant bias. The intermittent large spiking events show characteristic features of extreme events (EE) since they are larger than a statistically defined significant height. Under the influence of repulsive interactions and an impact of heterogeneity of damping parameters, the network splits into three sub-groups of junctions, one in incoherent rotational, another in coherent librational motion and a third sub-group originating EE. We are able to scan the whole population of junctions with their distinctive individual dynamical features either in EE mode or non-EE mode in parameter space. EE migrates spatially from one to another sub-group of junctions depending upon the repulsive strength and the damping parameter. For a weak repulsive coupling, all the junctions originate frequent large spiking events, in rotational motion when the average inter-spike-interval (ISI) is small, but it increases exponentially with repulsive interaction;it largely deviates from its exponential growth at a break point where EE triggers in a sub-group of junctions. The probability density of inter-event-intervals (IEI) in the subgroup exhibits a Poisson distribution. EE originates via instability of in-phase synchronization.

November 4: Seminar by Nataliya Stankevich - Russian Federation

Scientific seminar by Nataliya Stankevich from Russian Federation.
Title: Occurrence of hyperchaos via sequence of secondary Neimark-Sacker bifurcations.
Seminar will be held in the Seminar Room near Dean's Office in A22 building. Time 11.00.

Abstract: On the example of various dynamical systems, including autonomous and non-autonomous flows, discrete maps, it is shown that the formation of hyperchaos is associated with the development of the Shilnikov chaotic attractor containing a saddle-focus with a two-dimensional unstable manifold. The appearance of a saddle-focus with a two-dimensional unstable manifold occurs as a result of a sequence of Neimark-Sacker bifurcations. The presence of secondary Neimark-Sacker bifurcations can lead to the emergence of a hierarchy of chaotic and hyperchaotic attractors.

Painting exhibiton by Tomasz Kapitaniak: Fuma - the dog

Last Tuesday at 13.00 a great opening of painting exhibition titled "Fuma - the dog" by Tomasz Kapitaniak in J. Kinderman Palace at Piotrkowska 137 street in Lodz took place. 27 portraits of his dog, Fuma were shown to the public. The exhibition is open till March 22, entry is free.
Professor Kapitaniak underlined in his speech his love to dogs and art which were main reasons of so many nice paintings done. Additionally, he stated that dogs were mostly side subjects of paintings in Polish tradition, what pushed him to follow English and Scottish painters for who the dogs were the main subjects.

Dr P. Brzeski awards Best Doctoral Dissertation from PM of the Republic of Poland

Among the 25 laureates of the Prime Minister's awards for the best doctoral dissertations in 2016 is Dr Eng. Piotr Brzeski from our Division.
His doctoral thesisis entitled "Transfer of energy in conjugated oscillators." It has been done under supervision of dr hab. Przemysław Perlikowski, prof. LUT. The research deals with the optimization of dynamic vibration dampers, which are used, for example, to suppress the vibration of tall buildings. The research results show that simple modifications to the silencer design significantly improve their performance. For Dr. Brzeski, this is another great honor. A year ago, the young scientist became a grantee of the START program for the Polish Science Foundation.
