  2. 1. A lumped element transformer model including core losses and winding impedances

    Author : David Ribbenfjärd; Göran Engdahl; Arvid Broddefalk; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power transformer; hysteresis; dynamic hysteresis; eddy currents; excess eddy currents; leakage flux; winding model; core model; magnetic measurements; magnetic materials; Electrical engineering; Elektroteknik;

    Abstract : In order to design a power transformer it is important to understand its internal electromagnetic behaviour. That can be obtained by measurements on physical transformers, analytical expressions and computer simulations. READ MORE

  5. 3. Three-body systems in the no-core shell model

    Author : DANIEL SÄÄF; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; core swelling; halo nuclei; no-core shell model; nuclear physics; clusterization;

    Abstract : In this thesis we present the ab initio no-core shell model (NCSM) and we use that framework to study 6He and 6Li computed with a realistic nucleon- nucleon interaction. In particular, we present results for the point-proton radius and the ground-state energy. READ MORE

    Abstract : The latest developments of mobile devices include a variety of hardware features that allow for more rich data collection and services. Numerous sensors, Internet connectivity, low energy Bluetooth connectivity to other devices (e.g. READ MORE

  7. 5. Programming Model and Protocols for Reconfigurable Distributed Systems

    Author : Cosmin Ionel Arad; Seif Haridi; Gregory Chockler; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; distributed systems; programming model; message-passing concurrency; nested hierarchical composition; reactive components; software architecture; dynamic reconfiguration; multi-core; discrete-event simulation; peer-to-peer; testing; debugging; distributed key-value stores; data replication; consistency; linearizability; network partition tolerance; consistent hashing; self-organization; scalability; elasticity; fault tolerance; consistent quorums;

    Abstract : Distributed systems are everywhere. From large datacenters to mobile devices, an ever richer assortment of applications and services relies on distributed systems, infrastructure, and protocols. Despite their ubiquity, testing and debugging distributed systems remains notoriously hard. READ MORE
