Characterization and Enhancement of Antenna System Performance in Compact MIMO Terminals

Popular Abstract in Swedish I dagens nya cellulära kommunikationssystem betraktas användandet av multipla mottagarantenner i kompakta användarterminaler som en nödvändighet för att kunna utnyttja fördelarna med diversitet och MIMO (Multiple Input Multiple Output) teknik och därmed uppnå god celltäckning och hög dataöverföringshastighet. Den senaste utbyggnaden av det cellulära kommunikationssystemCo-band multiple-antenna implementation in compact user terminals is necessary for harvesting the full potential of diversity and multiple-input multiple-output (MIMO) technology in cellular communication systems. The recent worldwide deployment of Long Term Evolution (LTE), which requires the use of MIMO technology in the downlink, adds to the urgency of achieving both practical and optimal multi

Effects of an active accelerator pedal on driver behaviour and traffic safety after long-term use in urban areas

The long-term effects of the active accelerator pedal were evaluated in the city of Lund in 2000 and 2001. The system, installed in 284 vehicles, produced a counterforce in the accelerator pedal at the speed limit. It could, however be overridden by pressing the accelerator pedal harder. The results showed that test drivers’ compliance with the speed limits improved considerably. Reduction in aver

Affect School for chronic benign pain patients showed improved alexithymia assessments with TAS-20

Background: Alexithymia is a disturbance associated with psychosomatic disorders, pain syndromes, and a variety of psychiatric disorders. The Affect School (AS) based on Tomkins Affect Theory is a therapy focusing on innate affects and their physiological expressions, feelings, emotions and scripts. In this pilot study we tried the AS-intervention method in patients with chronic benign pain. Metho

The Generative Mechanisms of Healthcare Digitalization

Digitalization is considered as an important strategy to meet the challenges facing healthcare sector. However, the results often fall below expectations. Furthermore, the literature has provided a fragmented understanding as previous studies have generally focused on the advantages and the barriers of the adoption of health care IS. Very little attention has been paid to the generative mechanisms

Growth environment and personality in adult migraineurs and their migraine-free siblings

The aim of the study was to compare adult migraine discordant full siblings in terms of personality and psychosocial environment during childhood. The study, involving 30 sibling pairs and use of various personality instruments (Eysenck Personality Inventory [EPI], Color Word Test [CWT], Visual Aftereffects [VAE], Meta Contrast Technique [MCT], Cesarec-Marke Personality Schedule), showed the migra
