2. 1. Conceptual Politics in Practice : How Soft Power Changed the World

   Author : Stephanie Christine Winkler; Mark Rhinard; Linus Hagström; Patrick Thaddeus Jackson; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; academia policy nexus; alliance; China; concepts; critical concept studies; decline; feedback loops; interaction effects; International Relations; Japan; power shift; power; reification; rise; science; security; sharp power; smart power; soft power; travel; United States; internationella relationer; International Relations;

   Abstract : Concepts are a key feature of academic research and international politics. Despite the fact that interpreting, classifying and communicating the world through concepts has far-reaching social and political consequences, their various roles and complex dynamics remain poorly understood in International Relations (IR).

5. 3. Power System Operation Planning and Wind Power Curtailment : Efficient Methods for Power System Scheduling and Integration Studies of Variable Renewable Energy

   Author : Elis Nycander; Lennart Söder; Mehrdad Ghandari; Robert Eriksson; Germán Morales-España; Benjamin Hobbs; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Variable renewable energy; wind power integration; production cost model; power-based unit commitment; wind power scenarios; Electrical Engineering; Elektro- och systemteknik;

   Abstract : To reduce carbon dioxide emissions, variable renewable energy (VRE) sources are replacing conventional fossil-based power plants for electricity generation. Due to the variability and uncertainty of weather dependent VRE sources, there can be situations when it is not possible to accommodate all the available VRE production, and VRE sources have to be curtailed.

6. 4. Power line communication and customer equipment

   Author : Sarah Rönnberg; Pertti Pakonen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Power Engineering; Elkraftteknik; Energy Engineering; Energiteknik;

   Abstract : In Sweden, the change from manual meter reading at irregular intervals, to automatic remote meter reading at predefined instants was completed in July 2009. This change is ongoing or largely completed in a number of other European countries as well. Several methods for communication between the meter and the network operator are in use. READ MORE

7. 5. Primitive Direcursion and Difunctorial Semantics of Typed Object Calculus

   Author : Johan Glimming; Karl Meinke; John Power; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; denotational semantics; axiomatic domain theory; coalgebra; primitive co recursion; object-based programming; typed object calculus; Computer science; Datavetenskap; datalogi; Computer Science;

   Abstract : In the first part of this thesis, we contribute to the semantics of typed object calculus by giving (a) a category-theoretic denotational semantics using partial maps making use of an algebraic compactness assumption, (b) a notion of "wrappers'' by which algebraic datatypes can be represented as object types, and (c) proofs of computational soundness and adequacy of typed object calculus via Plotkin's FPC (with lazy operational semantics), thus making models of FPC suitable also for first-order typed object calculus (with recursive objects supporting method update, but not subtyping). It follows that a valid equation in the model induces operationally congruent terms in the language, so that program algebras can be studied. READ MORE
