Catch 22: Electric Vehicles and the Required Infrastructure
Saturday, 11:00 - 12:30, A201

Presentation

Abstract:

Vehicles have been almost exclusively run by the petroleum distillates ever since the introduction of modern internal combustion engine in 1885. As a result, the personal vehicles are responsible for at least 10% of greenhouse gas emissions worldwide. Besides these environmental issues, the volatility of crude oil prices and the advances in alternative fuel technologies have started generating new ideas on more ecological, cheaper and efficient vehicles. Recent commercial success of Nissan Leaf, Tesla and others, have put Electric Vehicles (EVs) in the spotlight. However, there are serious obstacles that need to be removed in order to make EVs attractive. For a successful rollout of EVs, it is required to establish an adequate charging infrastructure. However, investments in such infrastructure are only feasible if there is enough EVs using it, which resembles a Catch 22 scheme. Tesla is so far the only producer of EVs that has practically implemented supercharging stations and introduced the concept of battery swapping stations. The presentation will discuss the effective means of integration of EV infrastructure with an emphasis on Battery Swapping Stations as a critical infrastructure for elimination of long waiting times associated with charging the EV batteries.

A vision of sustainable energy future: A multi-energy concept of smart energy systems
Saturday, 11:45 - 12:30, A201

Presentation

Abstract:

We are becoming more and more aware of the problems created by today’s energy production and consumption “habits”. Air pollution and CO2 emissions are reaching their historical peaks while reports on polar caps reduction are warning us about the raise of the global temperature. Changes are needed and almost all energy strategies and policies promote switching from fossil fuel energy (such as coal, oil or gas) to renewable energy sources as a way of saving our planets future. This change does not only mean changes in the electricity sector, but also in other two main producers of greenhouse gas emissions – transport and heating. The percentage of electric vehicles on the roads is increasing and the same is the case with highly efficient electricity based heating, especially in European countries. It is important to keep in mind that these changes alone will not reduce pollution; if the electricity these “new” electric devices need is not produced from clean energy sources, the “switch” could actually have a negative impact on the environment.

There are many ideas how the future energy systems should look like. Although it is difficult to define only one common denominator of all the pathways proposed, most of them could be seen as concepts of planning and building a flexible system capable of responding to the stochastic nature of renewable sources. The concept presented in the lecture will challenge the idea of “all electrified energy future” and explain how we can create a sustainable low carbon energy future by interacting the existing sources, infrastructures and so called energy vectors (by energy vector we mean electricity, heat, gas, hydrogen, cooling and every other “useful” form of energy we consume today). This vision could change the perception of how most of us look at energy demand and supply. For instance, imagine that gas to warm up our houses is produced from photovoltaic power. Or that hydrogen, bio-fuel and electric vehicles circulate together on our roads. Did you ever think that we can use CO2 emitted from coal power stations and “blend” it with wind energy to produce synthetic gas which can then power gas power plants, our gas boilers at home or even gas driven vehicles? There are many examples like this: chilled water can be generated from hot flues of micro power stations located in basements; wastewater can be a resource to simultaneously cool and heat the buildings in our districts; and smart meters in our homes can indicate if it is cheaper to use gas or electricity to heat showering water. All depending how the weather behaves.

The concept of “smart grid” that goes “beyond electricity” will be present during the lecture with a goal to make you rethink the concept of energy as electricity only problem. The multi-energy idea offers a vision how to make changes today and not wait for feasible solutions that electricity only concepts require.

MMORPG sci. & research
Saturday, 11:00 - 12:30, A202

Presentation

Abstract:

The aim of the talk is to present the state of the gaming industry and its market characteristics with the focus on online games. The analysis of business models will be presented and the current trends explained with examples. Also the lecture will present a series of technical issues which plague online games today. Focus of the lecture is on the network component, and how the networking component of online games works.

Some other questions will be answered such as:
Who play online games?
What are the ways game developers extract money from their customers and which one is the most effective one?
WILL PC DIE? (Spoiler alert – it will not)
What are the technical challenges on the server level and what on the technical level?
Does DOTA 2 always lag a little or is it just me?
What are important technical differences between game genres?

Nao robots play tic-tac-toe
Saturday, 11:00 - 12:30, A301

Abstract:

Robotics is seen as a multidisciplinary field that embraces knowledge from different areas such as mechanics, electronics, computer science and control. Through this workshop we will try to use some of that knowledge to make our humanoid robots Nao more intelligent and fun by teaching them to play tic-tac-toe. By doing that, we will learn about the three crucial ingredients that make an intelligent robot: perception, reasoning and acting. In the first part we will use Nao's camera to detect the playing field and playing objects. In the second part we will use this information and combine it with knowledge of tic-tac-toe strategies to enable the robot to deduce the next best move. We will conclude the workshop with the control of robot's posture and arms needed to complete the move and integration of all three parts into a complete system.

Making of Radiona's donation box
Saturday, 11:00 - 12:30, A302

Abstract:

Donation box is an open source project developed with the aim of studying the toll systems and their use in DIY and DIWO projects. After the donation box prototype was made, a workshop was held where participants learned how donation box works and they made first Radiona's donation box.

On this workshop participants will make second donation box that will be used on presentations in which Radiona exibit their projects and in ther lab.

Donation box consists of box, Raspberry Pi computer, SD Card, two switches and coin mechanism. Switches change the image on the screen showing a specific organization, project or something else for what you want to donate money. By inserting coins, coin mechanism generates impulses that Raspberry Pi sums up and enters into database.

Donation box's computer code is written in Python programming language and Pygame is used for displaying of image. Every 5 minutes the database is updated and accessible on internet so everybody involved in donations can track the status of money in projects.

For easier creation of image and easier tracking of donation boxes the plan is to build Nodewatcher module (wlan slovenia open source network planning, deployment, monitoring and maintenance platform).

In it, the users can generate their own image for Raspberry and easily track data from their donation box through only few steps.
