PIRSA:14050040  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Recent advances in the search for complementary sequences
Speaker(s): Ilias Kotsireas
Abstract: We will present recent developments in the search for complementary sequences namely new theoretical and algorithmic progress. SHARCNET resources are used quite heavily in this project.

PIRSA:14050036  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Simulating the Capture and Translocation of Rigid fd Viruses though a Nanopore
Speaker(s): Hendrick de Hann
Abstract: The passage of long biological molecules from one side of a membrane to the other through a nanoscale hole has been the subject of intense research in recent years. Motivated by the possibility of new sequencing technologies the focus of this work has been studying the translocation of DNA across bi... read more

PIRSA:14050041  ( MP4 Medium Res , MP3 , PDF ) Which Format?
New insights into polymer-induced drag reduction in turbulent flows
Speaker(s): Li Xi
Abstract: Polymer additives are known to cause significant reduction in turbulent friction drag and reduce the energy dissipation rate of fluid transport. This effect is however bounded by a universal upper limit the maximum drag reduction (MDR) asymptote that does not change with polymer properties. Understa... read more

PIRSA:14050042  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Solving initial-boundary value problems without numerical differentiation
Speaker(s): Lennaert van Veen
Abstract: The numerical solution of nonlinear partial differential equations with nontrivial boundary conditions is central to many areas of modelling. When high accuracy is required (pseudo) spectral methods are usually the first choice. Typically in this approach we search for the pre-image under a linear o... read more

PIRSA:14050046  ( MP4 Medium Res , MP3 , PDF ) Which Format?
HPC Application in Large Eddy Simulation of Fuel Spray / Air Jet interaction
Speaker(s): Abbas Ghasemi
Abstract: Along with the development of computational resources computational fluid dynamics (CFD) has evolved in resolving the finest length scales and smallest time scales of the flow. Direct numerical simulation (DNS) resolves the finest flow scales known as Kolmogorov length scales which are responsible f... read more

PIRSA:14050043  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Biological graph dissimilarity characterization using graph theory
Speaker(s): Serene Wong
Abstract: Many biological data sets and relationships can be modeled as graphs. Understanding how structure of these graphs relates to biological function is essential for understanding underlining mechanisms of disease and for aiding drug discoveries. Vertices of biological graphs represent individual entiti... read more

PIRSA:14050047  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Modelling Surface Driven Flows in the Ocean
Speaker(s): Eric Bembenek
Abstract: Buoyancy driven flows at the top of the ocean or bottom of the atmosphere are inherently different from their interior dynamics. Oneidealized model that has recently become very popular to idealizethese surface flows with strong rotation is Surface Quasi-Geostrophic (SQG) dynamics. This model is app... read more

PIRSA:14050044  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Designing Electroencephalographic (EEG) analysis software with HPC in mind: Focus on a modular submission interface and flexible data annotation
Speaker(s): James Desjardins
Abstract: Electroencephalography (EEG) is a method for measuring brain activity by recording electrical fields at the scalp surface. Although it has the highest temporal resolution among brain imaging techniques it has low spatial resolution and is very sensitive to various forms of noise (e.g. movement artif... read more

PIRSA:14050037  ( MP4 Medium Res , MP3 , PDF ) Which Format?
HPC in Quantum Gravity
Abstract: Application of numerical simulations to quantum gravity are so far largely neglected yet they possess remarkable potential to learn more about the theory. For approaches that attempt to construct quantum spacetime from fundamental microscopical building blocks e.g. spin foam models the collective be... read more

PIRSA:14050045  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Testing Discontinuous Galerkin Methods in the Einstein Toolkit for Numerical Relativity
Speaker(s): Jonah Miller
Abstract: Discontinuous Galerkin finite element (DGFE) methods combine advantages of both finite differences and finite elements approaches. These methods scale extremely well and they have been very successful in computational fluid dynamics. As such we would like to transpose them to the domain of relativis... read more
