1. 1. Submerged Transmission in Wave Energy Converters : Full Scale In-Situ Experimental Measurements

   Författare :Erland Strömstedt; Mats Leijon; Hans Bernhoff; Jan-Olov Aidanpää; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave energy converter; direct drive; submerged transmission; piston rod; seal housing; sealing system; laser triangulation sensor; offshore measurements; relative displacement; vibrations; tilt angle; tilting; wear estimation.; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Sammanfattning : Different wave power technologies are in development around the world in different stages of prototype testing. So far only a few devices have been deployed offshore at full scale for extended periods of time. Little data is published about how these different devices perform. LÄS MER

3. 2. Learning Methods for Antenna Tilt Optimization

   Författare :Filippo Vannella; Alexandre Proutiere; Erik G. Larsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : The increasing complexity of modern mobile networks poses unprecedented challenges to Mobile Network Operators (MNOs). MNOs need to utilize network resources optimally to satisfy the growing demand of network users in a reliable manner. LÄS MER

4. 3. Liquid Crystalline SIloxane Dimers - Advanced Materials with Enhanced Properties

   Författare :Nils Olsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 45 degree tilt angle; dimer; antiferroelectric; fluorinated; siloxane; polymer; liquid crystal; macrocycle; ferroelectric;

   Sammanfattning : The liquid crystal state is a complex state with many kinds of different molecular attractive and repulsive forces that results in various kinds of phases. Since the pioneering works by Vorländer in the early 20th century, liquid crystal research has to a great extent been depending on careful systematic studies of the structure/property relationships in series of similar liquid crystalline materials.

7. 5. The subjective visual horizontal in the diagnosis of vestibular disorders : physiological and clinical considerations

   Författare :Arne Tribukait; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Vestibular system; vestibular tests; vestibular neuritis; Meniere sdisease; gentamicin treatment; vestibular compensation; stapedotomy; spatial orientation; gravity otoliths; utricle; saccule; semicircular canals; subjective visual horizontal; roll;

   Sammanfattning : In the examination of patients with vestibular disturbances the diagnostic techniques are almost entirely focused on the semicircular canals. However, a considerable number of the patients have symptoms which are suggestive of an affection of the otolith organs, e.g. false sensations of tilt or linear motion and even sudden falls. LÄS MER
