1. 1. Beröringens fenomenologi i vårdsammanhang

   Författare :Lise-Lotte Ozolins; Karin Dahlberg; Ulrica Hörberg; Gunn Engelsrud; Linnéuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Care; Caring science; Lifeworld; Lived body; Phenomenology; Reversibility; Touch; Caring sciences; Vårdvetenskap; Vårdvetenskap; Caring Science;

   Sammanfattning : This thesis explores the phenomenon of touch and describes its meaning in the healthcare context. Caring science theory based on a lifeworld approach forms the theoretical perspective of the dissertation and consequently the patient perspective is guiding the research. LÄS MER

4. 3. Det lärande utrymmet : lärande och vårdande möten mellan patienter, studentpar och handledare vid Utvecklande och Lärande Vårdenheter

   Författare :Hanna Holst; Ulrica Hörberg; Lise-Lotte Ozolins; David Brunt; Unni Lindström; Linnéuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; caring science; clinical practice; learning space; learning support; pairs of nursing students; reflective lifeworld approach; vårdvetenskap; verksamhetsförlagd utbildning; lärande utrymme; lärande stöd; par av sjuksköterskestudenter; reflekterande livsvärldsforskning; Vårdvetenskap; Caring Science;

   Sammanfattning : Aim: The overall aim is to create knowledge about how nursing students’ learning in pairs can be supported in order to create prerequisites for encounters that provide caring and learning support during clinical practice.Approach and method: A reflective lifeworld research (RLR) approach founded on the epistemology of phenomenology and hermeneutics was used.

5. 4. Frequency Noise in Coherent Optical Systems: Impact and Mitigation Methods

   Författare :Aditya Kakkar; Richard Schatz; Sergei Popov; Gunnar Jacobsen; Xiaodan Pang; Oskars Ozolins; Magnus Karlsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Equalization enhanced phase noise; frequency noise; coherent optical communications; carrier phase recovery; carrier phase estimation; circular quadrature amplitude modulation; EEPN; CmQAM; blind phase search; phase noise;

   Sammanfattning : The increase in capacity demand along with the advancement in digital signal processing (DSP) have recently revived the interest in coherent optical communications and led to its commercialization. However, design and development of robust DSP algorithms for example for carrier phase recovery (CPR) becomes complex as we opt for high order modulation formats such as 16QAM and beyond. LÄS MER

7. 5. Phase Noise Tolerant Modulation Formats and DSP Algorithms for Coherent Optical Systems

   Författare :Jaime Rodrigo Navarro; Sergei Popov; Gunnar Jacobsen; Richard Schatz; Xiaodan Pang; Oskars Ozolins; Gabriella Bosco; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical communications; carrier phase recovery; blind phase search; circular quadrature amplitude modulation; CmQAM; coherent optical communications; digital signal processing; carrier phase estimation; equalization enhanced phase noise; EEPN; Telecommunication; Telekommunikation;

   Sammanfattning : Coherent detection together with multilevel modulation formats has the potential to significantly increase the capacity of existing optical communication systems at no extra cost in signal bandwidth. However, these modulation formats are more susceptible to the impact of different noise sources and distortions as the distance between its constellation points in the complex plane reduces with the modulation index.
