How is it possible to meet the government's 2035-goals whilst continuously supplying district heating in Denmark at low costs and at a high security of supply? This semester project analyses the possibilities of replacing the in-renewable heat production from the coal-fired CHP production unit FV07 at Fynsværket, with large industrial heat pumps. When using heat pumps as the only supply unit, regulatory energy is required to maintain the security of supply. This project analyses the possibilities of using a heat storage facility to supply the district heating in times where the electricity price is _ high. To analyse the scenario, a MATLAB model is set up, minimising the hourly production costs and determining the minimum heat pump capacity and storage capacity needed to meet the demand in Fjernvarme Fyn's supply area. Legislative and financial aspects of shutting down CHP plants and integrating heat pumps are considered. As the district heating production becomes reliant on the electricity production, the overall consumer costs in a heat pump based network will fluctuate with respect to the Nordpool spot price. This could set the foundation for making the district heating sector hourly charged, allocating the demand and lowering the price. Furthermore, the model concludes that the overall costs in the heat pump scenario becomes significantly lower than in the current network, as the fuel costs, including the CO2-quotas, are eliminated.

This paper is describing a short view on the given case – You are in a modern national state where you have the democratic power to suggest/ put forward that “democracy and equality”, OR “democracy and freedom” are the highest values and norms in your society (the group chooses which of the two alternatives you want to answer on). What would your arguments and examples be to people of your country?

This investigation explores the conditions under which an object, moving through a liquid in high speed, has the greatest deceleration. The conditions focused on are the mass of the object, its initial velocity and its entry angle into the liquid. This is achieved through shooting pellets of varied masses and energies out of two different soft guns at a water container, recording them with a high speed camera and mapping their motion with a tracking program. The results of the experiment indicate that the lesser the mass of the object, the greater its deceleration in the fluid. The initial velocity and the entry angle of the object do not influence the rate of its speed loss. It is further explored that as the density of the fluid becomes greater, so does the deceleration of the object. The investigation is intended to deepen the understanding of the high speed motion through a medium.

Recent work on information extraction has suggested that fast, interactive tools can be highly effective; however, creating a usable system is challenging, and few publically available tools exist. In this paper we present IKE, a new extraction tool that performs fast, interactive bootstrapping to develop high-quality extraction patterns for targeted relations, and provides novel solutions to these usability concerns. In particular, it uses a novel query language that is expressive, easy to understand, and fast to execute - essential requirements for a practical system - and is the first interactive extraction tool to seamlessly integrate symbolic and distributional methods for search. An initial evaluation suggests that relation tables can be populated substantially faster than by manual pattern authoring or using fully automated tools, while retaining accuracy, an important step towards practical knowledge-base construction.
