1. 21. Physics from Wholeness : Dynamical Totality as a Conceptual Foundation for Physical Theories

   Författare :Barbara Piechocinska; Claes-Göran Granqvist; Erik Sjöqvist; Laszlo Kish; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; wholeness; elementary embedding; left-distributivity; braids; special braids; entropy; Temperley-Lieb algebra; von Neumann algebra; Potts model; Fysik; Physics; Fysik; fasta tillståndets fysik; Solid State Physics;

   Sammanfattning : Motivated by reductionism's current inability to encompass the quantum theory we explore an indivisible and dynamical wholeness as an underlying foundation for physics. After reviewing the role of wholeness in the quantum theory we set a philosophical background aiming at introducing an ontology, based on a dynamical wholeness. LÄS MER

3. 22. CALLUM Linear Transmitter - Architecture and Circuit Analysis

   Författare :Roland Strandberg; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; Telecommunication engineering; loop time delay; modulation negative feedback; spectral emissions; baseband model; CALLUM; Linear transmitter architecture; power amplifier linearization;

   Sammanfattning : This doctoral dissertation presents a study of linear radio transmitters based on the combined analog locked loop universal modulator (CALLUM) approach. Linear architectures such as CALLUM are very attractive for power-efficient operations, since they have no fundamental limitations prohibiting a 100% efficiency for all envelope levels, without sacrificing the potential of a linear transmission.

4. 23. Linguistically Informed Neural Dependency Parsing for Typologically Diverse Languages

   Författare :Miryam de Lhoneux; Joakim Nivre; Sara Stymne; Emily Bender; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Dependency parsing; multilingual NLP; Universal Dependencies; Linguistically informed NLP; Computational Linguistics; Datorlingvistik;

   Sammanfattning : This thesis presents several studies in neural dependency parsing for typologically diverse languages, using treebanks from Universal Dependencies (UD). The focus is on informing models with linguistic knowledge. LÄS MER

5. 24. Design for all Senses. Accessible Spaces for Visually Impaired Citizens

   Författare :Marta Dischinger; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design methods; spatial perception; urban accessibility; visual impairments; universal design;

   Sammanfattning : The central purpose of this study is to contribute to our knowledge of designing in a way that can be supported by the knowledge of the situation, and by the experience and expectations of those who are affected by design. In this case it means to enable us to find methods that can support the development of design actions to improve the accessibility of public open urban places for visually impaired persons, enhancing their perception and understanding of space, increasing their possibilities of orientating and taking independent decisions, and enabling them participate in the city life.

7. 25. Coexistence, Deployment and Business Models of Heterogeneous Wireless Systems Incorporating High Altitude Platforms

   Författare :Zhe Yang; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless communication; Coexistence; High altitude platforms; Resource sharing; Capacity; Business model; Techno-economic;

   Sammanfattning : The increased demand for broadband communications has led to the rapid development of the conventional terrestrial and satellite wireless communications systems. One of the main challenges to next generation wireless systems is to deliver high-capacity and cost-efficient solutions to cope with an increasing usage of broadband services and applications. LÄS MER
