The lighthouse in economics - the Swedish experienceBjörn Hasselgren
Presentation given at the second national Swedish transport research conference. Discusses the existence of different organizational models for providing services in transport infrastructure generally seen as cases for public sector provision, such as lighthouses. The presentation relates to Coase's 1974 article on "The lighhouse in economics".
This presentation is focused on the subject matter of Economics and Copyright law; it is the author’s participation in the 2014 international workshop, accompanied with a speech and full paper delivered within the scope of the International Conference titled Intellectual and Industrial ‘Property’: Bridging Historical, Philosophical and Policy Concerns.said participation in the workshop focuses on the influence of Information Technology in Copyright’s economics as these economics are understood in Microeconomics, and the influence that said understanding has on Copyright’s fundamental and core notions such as the excludability in the nature of Copyright. It is the speaker’s understanding that eventually Copyright’s economics press for changes in Copyright legislation and question core meanings of traditional Copyright notions such as the nature of property in Copyright law. It is mainly because of economic theories as they apply in Copyright that we need to reconsider the Copyright legal edifice, its undeniable need for existence and its questionable smooth co-existence with technological and societal changes in the Internet networking environment. Economic theory that considers the status quo and trends on the Internet and especially the public good nature that copyrighted works—and all information goods, actually, that become available through the Internet—acquire when they become available online is the cause for ground-breaking reconsideration in the field of Copyright law.
An industrial design is the ornamental or aesthetic visualization aspect of an article. The design may consist of three-dimensional features such as the shape and configuration of an article, or two-dimensional features, such as pattern and ornamentation. The design features must be applied to an article by any industrial process or means of which the features in the finished article appeal to eye.

Case Study :: Small Wind Turbines in the Built Environment Decommissioning GuideKimberly L. King
This case study covers the history of decommissioning an Aero Power SL1500 small wind turbine in Berkeley, CA, USA. The aim of this framework document is that it can serve as guidance, as far as it is practical, to those seeking to navigate and obtain approval for decommissioning wind turbines in the built environment or in urban settings.
There are the following global challenges:
• lack of energy
• lack of fresh water
• environmental problem
• saving the climate and life on the planet
The existing technology does not allow to avoid the potential disaster in 2050-2100. Suggested technology (Air Hydro Electric Station, Artificial Hydro Power) is perhaps the only one way that allows to avoid this.
Water Cycle is the most powerful process in Nature – about 1/4 of Sun’s Energy. Since the annual precipitation is about 1 m of rainfall, it matches a huge power ~ 800 TW that is more than 60 times greater than all the current needs of humanity and more than 400 times greater than all electrical power stations.
Why the usual Hydro power gives so little from Water Cycle power? Because the flow of all rivers is 11 times less than all precipitation and all rivers power is 200 times less than Cloud Power.
How to avoid this power loss?
• Collect water in place where it condenses really, i.e. directly in clouds
• Use all possible hydro power head in any place of land or ocean
We suggest the technology for realization this idea – Air HES, that allows to get water directly from clouds (by using a fog collector technology) in order to create artificial Hydro Power anywhere worldwide.
Major trend is the transition to renewable energy sources. It then becomes clear that resources are only sufficient for sun and (possibly) wind. Traditional hydro power does not have enough resources. However, the use of cloud energy changes this assessment.
Principally it results from economics. All three methods of conversion (PV, wind, clouds) are the same order of magnitude of the energy density (~ 100 W/m2) , but only for Air HES all this energy with virtually no loss can be merged into one point (pipe/turbine), making part of the proportional m2 far cheaper than other alternatives. This implies ROI > 1000% that allows quickly rebuild the energetics and successfully pass the collapse of energy & climate in 2050.
The Green Hydropower Solution, small hydro ,roaudet
Most inventions are not usually new: this new HUG (Helical Unique Generation), an invention, which is a combination of two inventions: the Gorlov helical turbine (1992), which is the child of the Darrieus turbine (1926), and vortex technology, developed by Schauberger (1929). A vortex pathway into which oval twin helical turbines are placed creates a marriage of two inventions: the Helical Pathway System, HUG (Patent Pending) and an oversize eggbeater.
The secret is in the natural motion of the water, which is a vortex. Water reduces resistance by curving more and more inwards thereby avoiding the confrontational resistance of straight motion. Nature has no use for the straight line: think of the water that leaves your bathtub; give it a twirl and see it speed up.
Canada has tremendous potential for small hydro development with more than 5500 identified sites (11,000 MW), especially in a free flow environment. It was estimated that as much as 3,400 MW of electricity generation potential could be exploited in U.S. rivers by small, unconventional systems such as free-flow turbines.
Water Swirled Into Gas Turbine Technology - Combined Cycle + 14% over current in use ! A patent technology that is covered in an issued patent and a patent that is overdue for issuance. The situation now is a electrical generation with 14% more than most efficient current combine cycle gas turbine - steam boiler steam turbine efficiency. This efficiency is for generation not overall. Overall is greatly improved by the water swirled in to gas turbine technology being very close in efficiency of 1 to 500 MW therefore allowing for an electrical grid with far less transition losses. The aircraft engine aspect ( + 20% Trans - Atlantic and +30% a Regional aspect ) is getting to the attention of the big airplane manufacturers.
Hydrogen Energy has a production process represented by different colors. This means that Hydrogen Energy can be produced with different energy sources.
These; It can be classified as Gray Hydrogen produced with fossil fuels, Blue Hydrogen produced with natural gas, Turquoise Hydrogen obtained by thermal cracking of methane, which is still in the experimental stage, and Green Hydrogen obtained by renewable energy.
Green Hydrogen is seen as an opportunity both to fulfill the commitments of the Paris Climate Agreement and to solve the world's energy problem.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Tides = rise and fall of sea levels
Oceans and seas are acted upon by the
• Gravitational forces of the sun and moon
• Rotation of the earth
Other influences such as wind and barometric
pressure changes, resulting in storm surges,
can also affect the sea water level
Tides vary daily (ebb – flood), monthly (spring – neap)
and can also have a seasonal variability

RESOURCE
Daily stages of tides:
Flood tide
High tide
Ebb tide
Low tide
Sea level rises over several hours, covering the intertidal zone
The water rises to its highest level
Sea level falls over several hours, revealing the intertidal zone
The water stops falling
2x/
day
*
Water levels continuously change as a consequence of moving water masses.
This implies water streams (currents, magnitude is bathymetry dependent)
In this context two main harvesting principles are applied:
Tidal barrage
Tidal current
Main advantage for capturing the resource is its predictability

Renewable Obligation Certificates (ROCs):
Tidal projects receive 5 ROCs / MWh
ROCs can be traded separately from the electricity
ROC prices are variable according to renewable energy production
Levy Exemption Certificates (LECs): £ 4.85 / MWh
Grey electricity price: highly variable since market dependent
Total varying income = ROCs + LECs + grey electricity price = € 340/MWh
(for 20 years if operational before 2017)
NEW support system (draft proposed ‘strike price’, June 2013)
fixed feed-in tariff = € 365 per MWh (guaranteed for 15 years)

27. SUMMARY
• Tidal energy has the potential to become the next generation of
offshore renewable energy: it can help to meet the climate change
targets and will bring social & economic benefits
• OEMs (Original Equipment Manufacturers) are getting organized for
further development and supply
• Incentives by governments and Europe are there to launch the
first tidal arrays (e.g. 7th Framework Programme, Horizon 2020,
Feed-in tariffs, etc.)
• First tidal projects are in the pipeline in Europe
• If challenges can be met and first projects prove to be economical
viable, this new industry is ready for commercialization
