2. 1. Development of theoretical approaches for post-silicon information processing

   Author : Viktor Ivády; Igor Abrikosov; Adam Gali; Erik Janzén; Risto Nieminen; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Despite knowing the fundamental equations in most of the physics research areas, still there is an unceasing need for theoretical method development, thanks to the more and more challenging problems addressed by the research community. The investigation of post-silicon, non-classical information processing is one of the new and rapidly developing areas that requires tremendous amount of theoretical support, new understanding, and accurate theoretical predictions.

4. 2. Characterisation and Modeling of Coupled-Core Optical Fibers

   Author : Ekaterina Deriushkina; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The growth in data traffic coupled with trends in internet use will result in a requirement for interfaces of the network to reach Tb/s data rate in the future. Considering this, novel transmission techniques that can increase the data rate with orders of magnitude must be considered. READ MORE

   Abstract : We are constantly struggling to understand how nature works, trying to identify recurrent events and looking for analogies and relations between objects or individuals. Knowing patterns of behavior is powerful and fundamental for survival of any species. READ MORE

6. 4. On the control of virtual violins : Physical modelling and control of bowed string instruments

   Author : Matthias Demoucron; Anders Askenfelt; Rene Causse; Benoit Fabre; Marcelo Wanderley; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bowed string; physical modelling; sound synthesis; performance control; violin playing; Corde frottée; modélisation physique; synthèse sonore; contrôle gestuel; violon; Struken sträng; fysikalisk modellering; ljudsyntes; musikutförande; violinspel; Other physics; Övrig fysik; Computer science; Datavetenskap; Acoustics; Akustik;

   Abstract :   This thesis treats the control of sound synthesis of bowed string instruments based on physical modelling. The work followed two approaches: (a) a systematic exploration of the influence of control parameters (bow force, bow velocity, and bow-bridge distance) on the output of a physical model of the violin, and (b) measurements and analyses of the bowing parameters in real violin playing in order to model and parameterize basic classes of bowing patterns for synthesis control.

7. 5. Data Analysis in High-Energy Physics as a Differentiable Program

   Author : Nathan Simpson; Partikel- och kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; differentiable programming; machine learning; particle physics;

   Abstract : Machine learning methods are now ubiquitous in physics, but often target objectives that are one or two steps removed from our physics goals. A prominent example of this is the discrimination between signal and background processes, which doesn’t account for the presence of systematic uncertainties – something crucial for the calculation of quantities such as the discovery significance and upper limits.
