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

Arithmetic Reduction of the Static Power Consumption in Nanoscale CMOS

The power consumption is becoming a major obstacle in future circuit design. Referring to Moore's law, by adding more functionality in an exponential way, we will also increase the total power consumption in the same pace. VLSI design has traditionally been concerning the dynamic power consumption as the limiting factor in low power system design. Today, when the feature sizes are in the nano-mete

Scattering Studies of Macromolecules in Solution

The sphere-to-rod transition of nonionic micelles of the PEO-PPO-PEO triblock copolymer P123 and the surfactant C12EO6 was studied using dynamic and static light scattering, small angel X-ray scattering, rheology and calorimetry. The transition temperature was dependent of the C12EO6/P123 molar ratio, which means that a larger content of C12EO6 yields a higher transition temperature. Furthermore,
