On impedance matching and bandwidth of compact antenna arrays

We analyze the impact of the matching network on compact MIMO systems. Existing studies have found that the matching network has a significant influence on the performance of multiple antenna systems when the antennas are in close proximity. However, none has examined the wideband case. In this paper, we investigate the wideband performance of four different matching networks for multiple dipole a

Triaxial strongly deformed band candidate in N=90 160Yb

A high-spin rotational band has been observed in the N=90 nucleus 160Yb with very similar moment of inertia and decay characteristics to recently discovered sequences in 157,158Er which have been discussed in terms of strongly deformed triaxial structures. Well-deformed triaxial shapes are indeed expected in 160Yb at high spin and detailed cranked Nilsson-Strutinsky calculations have been performe

Mellan fysisk bildning och aktivering : En studie av ämnet idrott och hälsa i skolår 9

The purpose of this dissertation is to explore and shed light on the subject content within Physical Education and Health (PEH). The first aim of the study is to describe and analyse what knowledge is legitimate within the subject, in the syllabus, as viewed by teachers and during the realisation of lessons. The second aim is to clarify and analyse similarities and dissimilarities between these th

The effects of active accelerator pedal in cars – Results from a large scale trial with intelligent speed adaptation.

Within the framework of the Swedish national trial with Intelligent Speed Adaptation (ISA) in urban areas, the effects of large scale use of “active accelerator” were evaluated. 284 cars were equipped with the system for a period of 5-11 months in the city of Lund. The driving data of all equipped vehicles were logged with regard to time and speed, both before and after activating the system. Driv

On the exact bit error probability for Viterbi decoding of convolutional codes

Forty years ago, Viterbi published upper bounds on both the first error event (burst error) and bit error probabilities for Viterbi decoding of convolutional codes. These bounds were derived using a signal flow chart technique for convolutional encoders. In 1995, Best et al. published a formula for the exact bit error probability for Viterbi decoding of the rate R=1/2, memory m=1 convolutional enc

Charge Transport in Semiconductor Nanowire Quantum Devices: From Single Quantum Dots to Topological Superconductors

This thesis focuses on charge transport in semiconductor InSb nanowire quantum devices, including the electron transport, the hole transport, and the Cooper pair transport. Devices in which InSb semiconductor nanowire quantum dots are coupled with normal metals, superconductors or the proximity effect induced topological superconductors are fabricated and measured. Firstly, we have fabricated and
