Modellansatz Podcast - English episodes only

modellansatz.de/en

On closer inspection, we find science and especially mathematics throughout our everyday lives, from the tap to automatic speed regulation on motorways, in medical technology or on our mobile phone. What the researchers, graduates and academic teachers in Karlsruhe puzzle about, you experience firsthand in our podcast "The modeling approach“.

Der Modellansatz

Everybody can subscribe to the podcast of Gudrun Thäter and Sebastian Ritterbusch under http://modellansatz.de/rss/en/ or from directory services such as iTunes. New episodes are announced under @modellansatz (twitter) as well as on Facebook.

This is the list of episodes published in English:


Modell148 16.11.2017Weather GeneratorWeather Generator: Bruno Pousinho modeled weather generators for planning renewable energy resources. Weather generators do not predict weather phenomena but provide random simulations with the same distributional properties as the measured weather data in the past.
Modell146 12.10.2017Advanced MathematicsAdvanced Mathematics: Gudrun Thäter and Jonathan Rollin introduce the lecture Advanced Mathematics, and give advice on how to best start studying Mathematics at the university.
Modell134 24.05.2017Cerebral Fluid FlowCerebral Fluid Flow: Marie Elisabeth Rognes is devoted to providing robust methods to solve PDEs for diverse applications, such as Cerebral fluid flow in the human brain as an exemplary application to her research.
Modell133 18.05.2017Convolution QuadratureConvolution Quadrature: Maria Lopez-Fernandez investigates robust and efficient approximation of convolutions with applications to wave scattering problems. She was one of the seven invited speakers at our conference Women in PDEs in April 2017 in Karlsruhe.
Modell121 19.01.2017Rage of the BlackboardRage of the Blackboard: The Rage of the Blackboard is the name of the blog of Constanza Rojas-Molina where she reaches out to women in her field to speak about their mathematical results as well as their experiences.
Modell119 22.12.2016Julia SetsJulia Sets: Pascal Kraft introduces us to Julia Sets. Although they are constructed by very simple formulae their shapes are surprisingly complex on any scale and turn out to be quite beautiful.
Modell116 01.12.2016HomogenizationHomogenization: Andrii Khrabustovskyi discusses his research interests Asymptotic analysis and homogenization of PDEs. Homogenization aims to replace a complicated inhomogeneous by a simpler homogeneous medium with similar properties and characteristics.
Modell112 03.11.2016FiltersFilters: Liliana Augusto investigates filtering devices which work on a micro and nano level, and computes the pressure drop between in- and outlet of the filter as well as the collection efficiency.
Modell109 13.10.2016Crime PreventionCrime Prevention: Andrea Bertozzi investigates the idea to model crimes of opportunity as being triggered by crimes that already happend. So the likelihood of new crimes can be predicted as an excitation in space and time like the shock of an earthquake.
Modell108 06.10.2016RobotsRobots: Anette Hosoi wanted to do fluid dynamics even before she had any course on that topic. Then she started to work as Assistant Professor at MIT where everyone wanted to build robots. So she had to find an intersection between fluid and roboters.
Modell094 02.06.2016Banach-Tarski ParadoxBanach-Tarski Paradox: Nicolas Monod teaches at the École polytechnique fédérale in Lausanne and leads the Ergodic and Geometric Group Theory group there. In May 2016 he was invited to give the Gauß lecture of the German Mathematical Society (DMV) at the Technical University in Dresden. He presented 100 Jahre Zweisamkeit – The Banach-Tarski Paradox.
Modell092 05.05.2016Viscoelastic FluidsViscoelastic Fluids: Helen Wilson studies viscoelastic fluids that combine viscous and elastic behaviour. Elastic effects in fluids often stem from clusters of particles or long polymers in the fluid, which align with the flow. It takes them a while to come back when the flow pattern changes. We can consider that as keeping a memory of what happened before.
Modell089 14.04.2016Crop GrowthCrop Growth: Josie Dodd develops models that describe plant and canopy growth of the Bambara Groundnut - especially the plant interaction when grown as part of a crop. The Bambara Groundnut is an remarkably robust crop and is therefore a candidate for adding to our food supply in the future.
Modell086 24.03.2016Complex GeometriesComplex Geometries: Before numerical simulations can take place, the computational domain has to be represented as a mesh which sometimes is hard to create. Therefore, Sandra May investigates a cut cell aproach to generate efficient meshes for complex geometries like airplanes or racing cars.
Modell075 17.12.2015Transparent BoundariesTransparent Boundaries: Sonia Fliss is interested in so-called transparent boundary conditions to compute the propagation of waves around an obstacle inside a an unbounded in-homogeneous domain. The artificial boundary conditions can help reducing the computational domain to a bounded domain.
Modell074 10.12.2015Population ModelsPopulation Models: How do populations evolve? This question inspired Alberto Saldaña to his PhD thesis. He considered an extended Lotka-Volterra models which is describing the dynamics of two species such as wolves.
Modell069 29.10.2015ElectrodynamicsElectrodynamics: The traditional model of Maxwell's equations for Electrodynamics is problematic for point charges. Therefore, Denis Bonheure investigates the nonlinear Born-Infeld model similar to the relativistic theory of Einstein.
Modell066 01.10.2015NanophotonicsNanophotonics: Nanophotonics is one great path into our future since it renders possible to build e.g. absorber, emitter or amplifier on a scale of a few dozen nanometers. The main focus of our guest Claire Scheid who is working on nanophotonics is to solve the corresponding partial differential equations numerically.
Modell062 30.07.2015Splitting WavesSplitting Waves: 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 wave splitting, which is the research topic of Marie Kray.
Modell058 02.07.2015Acoustic ScatteringAcoustic Scattering: Scattering is a phenomenon in the propagation of waves. An interesting example from our everyday experience is when sound waves hit obstacles the wave field gets distorted. So, in a way, we can "hear" the obstacle, illustrated by Francisco Sayas.
Modell054 07.05.2015WavesWaves: Indeed, waves are everywhere, illustrates Enrique Zuazua: They are visible in everything which vibrates and are an integral part of life itself. In our work as mathematician very often the task is to influence waves and vibrating structures like houses or antennae such that they remain stable.
