  1. 1. Word Representations for Emergent Communication and Natural Language Processing

    Författare :Mikael Kågebäck; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Extractive summarisation; Emergent communication; Deep reinforcement learning; Natural language processing; Word Representations; Deep learning; Machine learning; Artificial neural networks;

    Sammanfattning : The task of listing all semantic properties of a single word might seem manageable at first but as you unravel all the context dependent subtle variations in meaning that a word can encompass, you soon realize that precise mathematical definition of a word’s semantics is extremely difficult. In analogy, humans have no problem identifying their favorite pet in an image but the task of precisely defining how, is still beyond our capabilities. LÄS MER

  3. 2. Responsive Molecular Systems through Dynamic Covalent Chemistry

    Författare :Antanas Karalius; Zoltan Szabo; Stefan Matile; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stimuli-responsiveness; dynamic covalent reactions; systems chemistry; constitutional dynamics; non-equilibrium systems; nitroaldol reaction; dynamers; reversible polymerization; boronate ester; imine ligand; metal coordination; self–assembly; emergent properties; network topology.; stimuli-responsivitet; dynamiska kovalenta reaktioner; systemkemi; konstitutionell dynamik; icke-jämviktssystem; nitroaldolreaktion; dynamerer; reversibel polymerisation; boronester; iminligand; metallkoordination; själv-organisation; emergenta egenskaper; nätverkstopologi.; Kemi; Chemistry;

    Sammanfattning : Nature tends to inspire research in chemistry. Systems that emerge from molecules interacting via reaction networks is something that life has mastered over the course of evolution in order to produce complexity. Dynamic reactions are key in systems chemistry, where reaction networks give rise to complex, emergent behavior. LÄS MER

  4. 3. Collective properties of magnetic mesospins

    Författare :Erik Östman; Björgvin Hjörvarsson; Vassilios Kapaklis; Nicolas Rougemaille; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; artificial spin ice; magnetic nano-structures; mesoscopic spin systems; mesospins; mixed spin dimensionalities; interaction modifier; engineering of energy landscape; emergence;

    Sammanfattning : Mesoscopic spin systems consist of an ensemble of lithographically patterned nanomagnetic elements - mesospins. The interactions between the mesospins, can be designed at will by altering their lateral arrangement, enabling the study of collective magnetic order in a wide range of systems. LÄS MER

  5. 4. Understanding interest politics in social-ecological systems : Mechanisms behind emergent policy responses to environmental change

    Författare :Kirill Orach; Maja Schlüter; Henrik Österblom; Thorsten Blenckner; Scott Page; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Social-ecological system; policy process; interest group; agent-based modelling; process tracing; adaptive governance; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : Environmental policymaking is embedded in social-ecological systems (SES) that continuously evolve and change, often in unexpected and non-linear ways. Such challenges call for responsive policymaking that adjusts policy when new information and knowledge about social-ecological change is available. LÄS MER

  7. 5. A Comprehensive Experimental Approach to Multifunctional Quantum Materials and their Physical Properties : Geometry and Physics in Condensed Matter

    Författare :Elisabetta Nocerino; Martin Månsson; Stephen Blundell; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum materials; neutron; muon; X-ray; symmetry; phase transitions; Material and Nano Physics; Material- och nanofysik;

    Sammanfattning : This thesis ranges within the vast framework of experimental condensed matter physics. Several different systems, and physical phenomena, are presented here from a structuralist standpoint. LÄS MER
