1. 26. Glycolytic oscillations in individual yeast cells

   Författare :Anna-Karin Gustavsson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical manipulation; Microfluidics; Fluorescence microscopy; Single cell analysis; Saccharomyces cerevisiae; Glycolysis; Oscillations; NADH; Heterogeneity; Synchronization; Robustness; Universality;

   Sammanfattning : Oscillations in the concentration of yeast glycolytic intermediates have been intensively studied since the 1950s, but these studies have so far been limited to observations of average oscillatory behavior in synchronized cultures. Hence, it has remained unknown whether the onset of oscillations is a collective property of the population which requires a high cell density, or if individual cells can oscillate also in isolation.

3. 27. Modelling and optimization of gear shifting mechanism, Application to heavy vehicles transmission systems

   Författare :Muhammad Irfan; Chalmers tekniska högskola; []
   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; Pareto optimization; synchronization; constraint Lagrangian formalism; sensitivity analysis; Generic synchronizer;

   Sammanfattning : Without an efficient transmission system the idea of an efficient vehicle is incomplete. During running of the vehicle especially in case of heavy vehicles the transmission system has to face different situations during which the system possibly can lose its efficiency. LÄS MER

4. 28. Space-Time Algorithms for Mobile Communications

   Författare :Per Pelin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antenna array; model order selection; equalization; Bootstrap; space-time propagation; synchronization; RAKE-combiner; real data; data reduction; spatial diversity; finite alphabet;

   Sammanfattning : Algorithms are presented for space-time signal processing in mobile communication systems employing base station antenna arrays. Two main issues are concerned. Reception of data transmitted on the uplink (mobile to base station transmission), and estimation of the parameters of the space-time mobile channel. LÄS MER

5. 29. Millimeter-wave Communication and Radar Sensing — Opportunities, Challenges, and Solutions

   Författare :Sining An; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic; BiCMOS; OFDM; synchronization; Millimeter-wave; range accuracy; radar; communication system; micrometer; high data rate; frequency divider; wideband; phase modulated; monitoring; carrier recovery; distance measurement; mobile network; sensing; fast Fourier transformation FFT .; SiGe;

   Sammanfattning : With the development of communication and radar sensing technology, people are able to seek for a more convenient life and better experiences. The fifth generation (5G) mobile network provides high speed communication and internet services with a data rate up to several gigabit per second (Gbps). LÄS MER

7. 30. Fine motor timing ability - A study of syllable repetition and finger tapping in adults with developmental stuttering or Parkinson's disease compared with healthy adults

   Författare :Maria Sundqvist; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; motor timing; synchronization; finger tapping; syllable repetition; Developmental stuttering; Parkinson s disease;

   Sammanfattning : Aim and methods: The overall aim of this thesis was to explore the fine motor timing ability as manifested by speech motor and fine hand motor activity in persons with developmental stuttering or Parkinson’s disease, and in healthy adults. A test method for systematic comparison between speech motor timing and fine hand motor control was developed. LÄS MER
