If we are interested hinein the propagation of waves around a small region of interest, like e.g. an obstacle inside a very big ("unbounded") domain, one way to bring such problems to the computer and solve them numerically is to cut that unbounded domain to a bounded domain. But to have a well-posed Schwierigkeit we have to prescribe boundary conditions on the so-called artificial boundary, which are not inherent rein our original Harte nuss. This is a classical problem which is not only connected to wave phenomena. Sonia Fliss is interested rein so-called transparent boundary conditions. These are the boundary conditions on the artificial boundaries with just the right properties. There are several classical methods like perfectly matched layers (PML) around the region of interest. They are built to absorb incoming waves (complex stretching of space variable). But unfortunately this does not work for non-homogeneous media. Traditionally, also boundary integral equations were used to construct transparent boundary conditions. But hinein general, this is not possible for anisotropic media (or heterogenous media, e.g. having periodic properties). The main idea hinein the work of Sonia Fliss is quite simple: She surrounds the region of interest with half spaces (three or more).

Nevertheless, the model has to stay as simple as possible, while firstly, bridging the gap to complicated and more precise models, and secondly, staying interpretable to make people able to use it and understand its behaviour as non-mathematicians. This is the main group for which the models should Beryllium a useful Hilfsprogramm.

The science of sampling started hinein the 1940s with Claude Shannon who found fundamental limits of signal processing. He developed a precise framework - the so-called information theory. Sampling and reconstruction theory is important because it serves as a bridge between the modern digital world and the analog world of continuous functions. It is surprising to see how many applications rely on taking samples hinein order to understand processes. A few examples rein our everyday life are: Audio signal processing (electrical signals representing sound of speech or music), image processing, and wireless communication. But also seismology or genomics can only develop models by taking very intelligent sample measurements, or, rein other words, by making the most scientific sense out of available measurements. The new development hinein dynamical sampling is, that rein following a process over time it might by possible to find good options to gain valuable information about the process at different time instances, as well as different spatial locations. In practice, increasing the number of spatially used sensors is more expensive (or even impossible) than increasing the temporal sampling density. These issues are overcome by a spatio-temporal sampling framework in evolution processes. The idea is to use a reduced number of sensors with each being activated more frequently. Roza refers to a paper by Enrique Zuazua (...)

To separate one single instrument from the acoustic sound of a whole orchestra- just by knowing its exact position- gives a good idea of the concept of anonymous wave splitting, the research topic of Marie Kray.

It provides a bath for human brain. The brain expands and contracts with each heartbeat and appoximately 1 ml of fluid is interchanged between brain and spinal area. What the specialists do not know is: Is there a circulation of fluid? This is especially interesting since there is no traditional lymphatic Organisation to transport away the biological waste of the brain (this process is at work everywhere else rein our body). So how does the brain get rid of its litter? There are several hyotheses: Diffusion processes, Fast flow (and transport) along the space near blood vessel, Convection. The aim of Marie's work is to numerically test these (and other) hypotheses. Basic testing starts on very idalised geometries. For the overall picture one useful simplified geometry is the annulus i.e. a region bounded by two concentric circles. For the microlevel-look a small cube can Beryllium the chosen geometry. As material law the flow in a porous medium which is based on Darcy flow is the starting point - maybe taking into account the coupling with an elastic behaviour on the boundary. The difficult non-mathematical questions which have to be answered are: How to use clinical data for estabilishing and testing models How to prescribe the forces Rein the near future she hopes to better understand the multiscale character of the processes. Here especially for embedding 1d- into 3d-geometry there is almost no theory available. For the project Marie has been awarded a FRIPRO (...)

Since 2018 she has been a postdoc at the MPI MSI in Leipzig and likes the very applied focus especially on algebraic statistics. Rein her experience Mathematics is a good topic to work on rein different places and it is important to have role models in your field.

Rein the study of Hochschulprofessor. Zuazua the interaction between the numerical grid and the propagation of waves of different frequencies leads to very intuitive results which also provide clear guidelines what to do about the so-called spurious wave phenomena produced by high frequencies, an example of which is shown hinein this podcast Folge image.

Sandra May works at the Seminar for Applied Mathematics at ETH Zurich and visited Karlsruhe for a Magnesiumsilikathydrat at the CRC Wave phenomena. Her research is rein numerical analysis, more specifically in numerical methods for solving PDEs. The focus is on hyperbolic PDEs and systems of conservation laws. She is both interested in theoretical aspects (such as proving stability of a certain method) and practical aspects (such as working on high-performance implementations of algorithms).

Das ist ein dramatischer Ausfall an Information, mit dem die Piloten aber umgehen können müssten und der eigentlich nicht zu einem Bluescreen führen sollte, denn die Geschwindigkeit ist noch mittels anderer Sensoren merklich. Erste gefundene Wrackteile deuteten darauf hin, dass Dasjenige Flugzeug fast lotrecht rein horizontaler Lage auf Dasjenige Wasser aufgeschlagen sein musste. Dies führte auf die Verdacht, dass das Flugzeug überzogen wurde, solange bis es zum Strömungsabriss kam, zumal es daraufhin einfach herunterfiel.

Micro grids are small scale electrical grid systems where self-sufficient supply is achieved. Therefore, the integration of micro grid design within district planning processes should Beryllium developed efficiently. Rein the planning process of districts with decentralised energy systems, unique and customised design of micro grids is usually required to meet local technical, economical and environmental needs. From a technical standpoint, a detailed understanding of factors such as load use, generation potential and site constraints are needed to correctly and most efficiently design and implement the network. The presence of many different actors and stakeholders contribute to the complexity of the planning process, where varying levels of technical experience and disparate methods of working across teams is commonplace.
