CESC
Centre for Sustainable Communications
Green Hackathon

Stockholm, London, Athens, Helsinki, Zürich, Barcelona, Berlin – Europe is hacking for a sustainable future. CESC created the concept Green Hackathon and started a series of events where developers create prototypes for sustainability. We present some of the most interesting hacks that have emerged during recent Green Hackathon events. www.greenhackathon.com

BiMaC Innovation
3D-shaped paper package

Development of double curved surfaces has been an important activity. This is done using both mechanical and chemical approaches. This can enlarge the utility space for paper based packages, since new package designs and concept can be developed. A demonstrator that has been used is the development of a paperbased Tetra Top, which today is made by plastic.

BiMaC Innovation
Numerical tools for product development

Paper material is extremely anisotropic, the out-of-plane direction is a factor 100 weaker than the in-plane directions. Therefore, material models ,that efficiently can be used to model paper materials using FEM, has been lacking. A material model and simulation tools have been developed, which are both used to make product development more efficient. This has been used to study forming of double curves surfaces, and of creasing and folding.

BiMaC Innovation
Multi-layer paperboard package material

The product inside a package is protected by the stiffness and strength provided by the paperboard layer, moisture and oxygen barriers provided by the polymeric layers, and a light and oxygen barrier provided by the aluminium layer. The objective in BiMaC innovation is to replace the different barrier layers with sustainable and biobased materials.

BiMaC Innovation
Molecular-engineered lignocellulosic structures

By altering the chemical structure of cellulose it is possible to produce papers that are both strong and formable. The photos show: A pear-shaped structure, i.e. a non-symmetric shape, formed from a flat paper (left). The required nominal strain over the greatest curvature is over 30 %. By further processing the modified fibres into nanosized fibres (referred to as nanofibrils) it is also possible to fabricate strainable and formable films (right). The nominal strain over the curvature of the displayed film is 24 %. Up to a relative humidity of at least 80 %, these films act as excellent oxygen barriers and may therefore be of interest in several packaging applications.

ProNova
Miniaturized protein analysis tools

Research projects in the ProNova Centre aim to develop methods that can be used to identify new, disease-related protein biomarkers and to develop fast and inexpensive technologies for measuring a particular biomarker, once it has been discovered and validated by other methods. Different miniaturized protein analysis tools, such as microarray technologies and microfluidics chips, are used to enable high-throughput analysis with minimal requirements of sample. This demo shows some of the miniaturized protein analysis tools that are developed and used in the ProNova Centre research.

hero-m

Simulations and in-situ studies of phase transformations. Demonstration on what can be done through computer simulations today i.e. creating ternary phase diagrams that previously was a tedious task.

Mobile Life
Fight boredom in the control room!

We have been asked to bring enjoyment and fun into the control rooms of large factories. As previous studies have shown boredom can be one reason for it being hard to attract talented engineers to want to work in these environments. See our probes used for a field study at Kraftvärmeverket in Västerås.

Mobile Life
iPhone InVivo

Using device recording software to capture use and surrounding practices we work to understand the role of mobile devices in everyday interaction.  For this demo we will show examples of the videos captured, the different systems we use to record this data and the tools we are using to explore the differences between sharing practices of live and recorded mobile device use.

Mobile Life
Instant Broadcasting System

Instant Broadcasting System (IBS) is a mobile broadcasting system that enables users to collaboratively produce, edit and broadcast live video using only mobile phones, a laptop computer and available mobile networks. It is a miniaturized live TV production system where mobile phones are used instead of cameras and, a computer instead of TV production room.

Mobile Life
Affective health

We will demonstrate a system that measures your pulse, movement and arousal level through bio-sensors attached to your body. These three measurements can indicate how you live your life. Over time it can portray situations that are stressful, engaging as well as peaceful moments in your life. The bio-sensor data is displayed in real time on the mobile phone. It is visualized using shapes and a colour scheme that builds from the energy level that different colours contain.

Exploring Big Data

Exploring Big Data is a proof of concept demo that shows how big data can be made meaningful by performing proper analysis on it, by visualizing it in various ways, and by making it possible to interact with it. Furthermore, the prototype also illustrates how different kinds of value can be extracted based on insights derived from mobile network data analysis. This demo is the result of a joint project between the User Experience Lab and the Data Research team at Ericsson Research's Software and Services research area.

Ericsson
Connected City

Connected City is a demo that exemplifies how data feeds produced by connected citizens or things can be combined, and together with situational knowledge lead to informed actions and recommendations for both citizens and public services. The interactive visualization contains three scenarios that demonstrate the technical enablers we have developed, highlighting holistic, proactive and collaborative aspects of city operations. It is a joint effort from the User Experience Lab and the other teams at Ericsson Research's Software and Services research area.

EXSELENT
CO2 Sorption

The combustion of fossil fuels continues to supply the world with a majority of its commercial energy and large amounts of carbon dioxide is released to the atmosphere. This associated release have triggered changes in the climate and researchers are searching for means to reduced these emissions. Carbon capture and storage (CCS) has emerged as a potentially viable approach. Well designed adsorbents for carbon dioxide could reduce the costs of CCS as compared with today’s approaches. Here, we demonstrate practically the effect of carbon dioxide capture on an adsorbent. You will be able to observe the changes to the pressure and volume of the carbon dioxide gas as well as feel the heat that develops in the adsorbent during adsorption.
