event picture

Barcelona Edifici Històric UB 11/05/2018

L’11 de maig del 2018, de 9.00 a 14.00 h, tindrà lloc a l’Edifici Històric de la Universitat de Barcelona la jornada de divulgació científica més festiva de la UB. Al llarg del matí, la seu central de la Universitat s’omplirà de tota mena d’activitats pràctiques i de caràcter científic, com ara demostracions d’investigadors, tallers, jocs...

L’objectiu de la festa és fer accessible a tots els públics, d’una manera lúdica i innovadora, la recerca que es duu a terme a la Universitat de Barcelona, i alhora reivindicar el paper rellevant de la ciència en tots els àmbits de la vida. Les activitats i els tallers programats pretenen fomentar la descoberta de la ciència que ens envolta i estimular la capacitat dels participants d’adoptar una actitud reflexiva i científica davant de qualsevol situació.

Si sou un grup escolar, cal que us inscriviu prèviament a l’activitat; així podrem organitzar la vostra visita i us oferirem material complementari. Si sou una família o veniu sols no cal inscripció, simplement veniu a gaudir de la jornada.

Esteu preparats per a la festa? Som-hi!

Tothom hi està convidat!

L'ÚBICS serà present a la XIII Fira d'Empreses, cerqueu el nostre stand.

La Fira d’Empreses de les facultats de Física i de Química, amb la participació de les facultats de Matemàtiques i Informàtica, Ciències de la Terra i Biologia, és una oportunitat perquè els estudiants contactin amb empreses d’activitats relacionades amb els estudis que estan cursant.

D’aquest contacte estudiant-empresa en pot sorgir una beca, un conveni per estada en pràctiques externes o un contracte de treball. Una altra cosa important per a l’estudiant, que la Fira d'Empreses pot aportar, és la formació en competències d’establiment de relació amb empreses, com ara dissenyar i presentar un bon currículum, fer una bona entrevista de treball, etc.

La Fira d’Empreses és també un marc perquè els investigadors dels grups de recerca estableixin relacions d’investigació/transferència. Representa un intent de superar la barrera universitat/empresa i d’impulsar la transferència tecnològica, tan important per al futur.

Va dirigida als estudiants dels ensenyaments cursats a les facultats organitzadores, en concret dels graus de:

  • Biologia
  • Bioquímica
  • Biotecnologia
  • Ciències Ambientals
  • Ciències Biomèdiques
  • Enginyeria Biomèdica
  • Enginyeria de Materials
  • Enginyeria Electrònica de Telecomunicació
  • Enginyeria Geològica
  • Enginyeria Informàtica
  • Enginyeria Química
  • Física
  • Geologia
  • Matemàtiques
  • Química

També està destinada a tots els estudiants dels màsters impartits a les facultats organitzadores.

Seminar: Understanding transition to turbulence in fluids: computing hidden flows and beyond

Barcelona Facultat de Física 02/02/2018

Understanding transition to turbulence in fluids: computing hidden flows and beyond
Alvar Messeguer Departament de Física, Universitat Politècnica de Catalunya alvaro.meseguer(at)upc.edu
  Hora: 11:45
Lloc: sala de graus antiga de la Facultat de Física de la UB     Predicting when and how a fluid in laminar motion may become turbulent is one of the most challenging (and yet unsolved) fundamental problems of classical physics. Current computational power allows for the accurate numerical simulation of fluid flows by means of CFD (Computational Fluid Dynamics) software packages. The majority of CFD codes currently used by scientists and engineers are essentially time evolution solvers (also termed as time-steppers)
of the fluid that provide time integrations of the Navier-Stokes initial value problem. Therefore, classical CFD codes can only reproduce stable flows, regardless the nature of their dynamics: steady, time-periodic, almost-periodic or chaotic. In other words, current standard CFD time-stepping codes can only identify local attractors. Recent studies [2,1] have clearly evidenced that the destabilization of many open flows (such as the ones appearing in pipes or channels) may be related to the presence of unstable Navier-Stokes solutions close to the stable base flow. Forecasting hydrodynamic instabilities in many fluid flows therefore requires the detection of the presence of these repelling Navier-Stokes solutions and their eventual computation. These exact Navier-Stokes flows are hidden since they are unstable and cannot be approached by standard CFD time-stepping codes. Numerical computation of these types of unstable flows is an even more challenging task, where new mathematical concepts such edge state dynamics and top-notch numerical weaponry such as Newton-Krylov-Poincare solvers are required. These techniques allow for the computation of unstable steady flows, as well as travelling waves, or modulated travelling pulses.   In this talk we will describe different strategies and techniques used to identify these hidden or unstable Navier-Stokes flows (from steady profiles, to travelling waves or relative periodic orbits) responsible for the transition. We will also explain how to track their linear stability when the parameters of the problem are varied so that bifurcations can be anticipated. Whereas these techniques have been essentially developed within the framework of fluid dynamics, they can easily be adapted to explore the phase space of other deterministic nonlinear PDE arising in physics.   [1] Deguchi, K., Meseguer, A. and Mellibovsky, F., Phys.

Cell Surface as an Active Composite - local control of forces and composition with

Abstract

Over the years we and others have shown that the physical organization and dynamics of
many signaling molecules at the cell surface are locally controlled by their coupling to the thin
cortical actomyosin layer, which actively drives local cell membrane composition and shape.
In many cases, this organisation involves a collaboration with specific lipids on the cell surface.
While this active organisation occurs constitutively, it gets locally amplified by external cues. I
will discuss our current understanding in terms of both theory and experiments. Towards the
end, I hope to be able to discuss possible functional implications of such a local active control

MACFANG

Barcelona Centre Cívic Pati Llimona 06/11/2017

Many real networks are embedded in space, either explicitly, as in airport and urban networks, or in a hidden fashion, like latent distances underlying the AS Internet or molecular interactions in the cell. The study of how space shapes the structure and function of these networks has become a hot topic, leading to the emergence of Network Geometry. Advances in this area unleash an unprecedented potential for mapping real networks and for practical applications of high impact in society. 

The Macfang workshop focuses on the role of space in complex networks. We bring exciting speakers from around the world to foster a leading collaborative view on the emergent field of Network Geometry. A number of topics will be covered, including but not limited to multiplex network geometry, distance-based link prediction, geometric networks at criticality, emerging geometries of evolving networks, and the importance of space in processes such as disease propagation.

It is with great pleasure that we invite you to join us at the International Congress “Complex Systems in Sports: Linking Theory and Practice“, to be held on the 5th and 6th of October in Barcelona.

The main aim of this International Congress of Complex Systems in Sport is to bring together the sport scientists and specialists of different disciplines from all over the world who are interested in developing new approaches and strategies for sport performance based on Complex Systems Science.

INEFC’s Complex Systems in Sport Research Group has reunited a stellar array of Invited Speakers and the Scientific Committee has built a programme format that encourages interaction among the participants covering multiple aspects of important and emerging topics such as talent detection, training methodologies, game analysis, performance assessment, team dynamics and leadership in a multidisciplinary scenario where scientists, coaches, trainers, students, and sport-related professionals will exchange their ideas for contributing to the development of research, theory, and practice in the field of sport.

BARÇA INNOVATION HUB hosts this event at the mythical FC Barcelona Stadium “Camp Nou” a unique exciting venue! Barcelona, our town, is a Mediterranean city open to people and to the world, known for its dynamic nature and for being a vibrant international meeting point.
