2. 1. Argument Differentiation. Soft constraints and data-driven models

   Author : Lilja Øvrelid; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; syntactic arguments; parsing; lexical acquisition; animacy; Scandinavian syntax; soft constraints; data-driven models; machine learning;

   Abstract : The ability to distinguish between different types of arguments is central to syntactic analysis, whether studied from a theoretical or computational point of view. This thesis investigates the influence and interaction of linguistic properties of syntactic arguments in argument differentiation. READ MORE

4. 2. On soft-switching isolated AC/DC converters without auxiliary circuit

   Author : Staffan Norrga; Stefan Östlund; Rik De Doncker; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical power technology; voltage source converter; cycloconverter; isolated converter; medium frequency transformer; soft switching; modulation; commutation; wind power; electric traction; Elkraftteknik; Electric power engineering; Elkraftteknik;

   Abstract : The thesis is concerned with a class of power electronic converter systems that permit bidirectional AC/DC conversion with galvanic separation of the AC and DC sides by a transformer operating at elevated frequency. The systems consist of a capacitively snubbered voltage source converter and a cycloconverter, separated by the mentioned transformer. READ MORE

6. 4. Techniques to Improve Energy Efficiency on Heterogeneous Multiprocessors under Timing and Quality Constraints

   Author : Muhammad Waqar Azhar; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thread throttling; Energy Efficiency; Dynamic Voltage Frequency Scaling DVFS ; Quality of Service; Heterogeneous multiprocessor; Soft real time systems.; Resource management; Core migration;

   Abstract : Traditionally, applications are executed without the notion of a computational deadline and often use all available system resources, which leads to higher energy consumption. User specification of Quality of Service (QoS) constraints, in terms of completion time and solution quality, opens up for allocation of just enough resources to an application to finish just in time and thereby save energy.

7. 5. Funnel-Based Control for Coupled Spatiotemporal Specifications

   Author : Farhad Mehdifar; Dimos V. Dimarogonas; Charalampos P. Bechlioulis; Bayu Jayawardhana; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Funnel-Based Control; Prescribed Performance Control; Uncertain Nonlinear Systems; Time-Varying Output Constraints; Coupled Spatiotemporal Constraints; Formation Control; Multi-Agent Systems; Trattbaserad kontroll; föreskriven prestandakontroll; osäkra icke-linjära system; tidsvarierande utgångsbegränsningar; kopplade rumsliga begränsningar; formationskontroll; multiagentsystem; Electrical Engineering; Elektro- och systemteknik;

   Abstract : In the past decade, the integration of spatiotemporal constraints into control systems has emerged as a crucial necessity, driven by the demand for enhanced performance, guaranteed safety, and the execution of complex tasks. Spatiotemporal constraints involve criteria that are dependent on both space and time, which can be represented by time-varying constraints in nonlinear control systems. READ MORE
