Visual Computing Forum

The Visual Computing Forum, or VCF, is a series of seminars organized by the visualization group with selected talks from the fields of visualization, image processing, computer graphics, and so on. The individual seminars are arranged approximately once a month, on Fridays from 11am to 12am, and they will be interleaved with the MedViz seminars. They will be held either at the Høyteknologisenteret or at the VilVite Science Center.

Title: Perfusion modeling - The link between reservoir simulation and medical compartment modeling

Speaker: Erik Hanson

Place: Room 302O1 (former 3137), 3rd floor Høyteknologisenteret

Time: Friday May 27, 2016, from 10:15am to 11:00am

Perfusion, the amount of blood feeding a volume of tissue, has for decades been possible to measure using medical imaging techniques and simple mathematical models. The imaging technology and the mathematical and numerical tools needed to solve the models have evolved rapidly over this period. At the same time, the models themselves have not changed accordingly. In this talk we will se how methods for modeling of porous media flow may contribute to a better mathematical understanding of perfusion modeling. The pressure driven flow trough a capillary system is an essential concept both in perfusion and reservoir/porous media simulation. We will discuss how this link may contribute to an improved modeling framework suited to make use of the extensive amount of information accessible through modern 4D medical imaging.

Title: Untangling intracellular signaling network in cancer

Speaker: Bjørn Tore Gjertsen

Place: Room 302O1 (former 3137), 3rd floor Høyteknologisenteret

Time: Friday April 22, 2016, from 10:15am to 11:00am

Protein and gene networks centered on the regulatory tumor suppressor proteins may be of crucial importance both in carcinogenesis and in the response to chemotherapy. Tumor suppressor protein p53 integrates intracellular data in stress responses, receiving signals and translating these into differential gene expression. Interpretation of the data integrated on p53 may therefore reveal the response to therapy in cancer. Proteomics offers more specific data – closer to “the real action” – than the hitherto more frequently used gene expression profiling.
We are currently working with single cell immune profiles that include information about intracellular signaling systems. Patient cancer cells are sampled before and under therapy to determine response or therapy failure as early as possible, thereby adjusting therapy to the benefit of the patient. Data visualization tools have been imperative for our interpretation of measurements. The question open for discussion is if we need better data visualization tools to easy grasp the dynamics of cancer, and if we have these tools available for visualization with exponentially increasing data density.

Title: Seismic imaging and model building

Speaker: Ola Kristoffer Øye

Place: Room 3137, 3rd floor Høyteknologisenteret

Time: Friday March 18, 2016, from 10:15am to 11:00am

Seismic imaging is an important tool for understanding the subsurface in oil and gas exploration and production. Going from recorded seismic data to a high resolution seismic image requires several steps of data processing, model building and migration, often run through several iterations. In this talk I will cover some of the techniques involved in the seismic imaging pipeline, with focus on data driven model building and migration. I will cover how data and images can be analyzed in different domains, and discuss some of the challenges in producing high quality seismic images.

Title: Visualization, story telling, and the big picture.

Speaker: Rasmus Slaattelid

Place: Room 3137, 3rd floor Høyteknologisenteret

Time: Friday Febraury 19, 2016, from 10:15am to 11:00am

At the University of Bergen, there exists several research environments that focus on visualizations. Visualizations of data, or of scientific knowledge more generally, visual cultures, diagrammatic thinking, and story-telling in visual media. If we look beyond the UoB, the picture grows even more diverse. This multitude of approaches and interests already suggests that a comprehensive understanding of visualization as a cognitive tool within one discipline is difficult, and that more collaboration across these disciplinary divides would be fruitful. The aim of my talk is to present some possible common areas of interest between different disciplines studying visualizations.

Title: What is going on at the IRIS offices in the 8th floor?

Speaker: Rodica Mihai and Geir Nævdal

Place: Room 3137, 3rd floor Høyteknologisenteret

Time: Friday January 29, 2016, from 10:15am to 11:00am

IRIS has an extensive research activity within energy, social sciences and marine biology. Main areas for IRIS Energy are drilling and well technology, reservoir technology, green technologies and research testing facilities. We will give a short introduction to our work within real time modelling of the drilling process and name some of its challenges. Products of this work are among others, an unique simulation environment called Virtual Rig as well as automated drilling solutions which have been successfully implemented offshore. In the second part of the presentation we will introduce shortly our work on ensemble based methods for large scale parameter estimation and optimizations problems, with a particular focus on flow in porous media, namely oil reservoirs. Main research area in IRIS has been so far oil related but we have currently increasing ongoing research activity to apply similar techniques within other research areas such as medicine research, i.e. blood flow modelling
