Evaluation of Haptic Patterns on a Steering Wheel
Infotainment Systems can increase mental workload and divert
visual attention away from looking ahead on the roads.
When these systems give information to the driver, provide
it through the tactile channel on the steering, it wheel might
improve driving behaviour and safety. This paper describes an
investigation into the perceivability of haptic feedback patterns
using an actuated surface on a steering wheel. Six solenoids
were embedded along the rim of the steering wheel creating
three bumps under each palm. Maximally, four of the six
solenoids were actuated simultaneously, resulting in 56 patterns
to test. Participants were asked to keep in the middle
road of the driving simulator as good as possible. Overall
recognition accuracy of the haptic patterns was 81.3%, where
identification rate increased with decreasing number of active
solenoids (up to 92.2% for a single solenoid). There was no
significant increase in lane deviation or steering angle during
haptic pattern presentation. These results suggest that drivers
can reliably distinguish between cutaneous patterns presented
on the steering wheel. Our findings can assist in delivering
non-critical messages to the driver (e.g. driving performance,
incoming text messages, etc.) without decreasing driving performance
or increasing perceived mental workload

Arizona v. Johnson: Determining When a Terry Stop Becomes Consensual
The study of crowding effects on particle diffusion is a large subject with implications in many scientific areas. The studies span from pure theoretical calculations to experiments actually measuring the movement of proteins diffusing in a cell. Even though the subject is important and has been studied heavily there are still aspects not fully understood.  This report describes a Monte Carlo simulation approach (Gillespie algorithm) to study the effects of crowding on particle diffusion in a quasi one-dimensional system. With quasi meaning that the particles diffuses on a one-dimensional lattice but has the possibility to disassociate from the lattice and then rebind at a latter stage. Different binding strategies are considered: rebinding to the same location and randomly choosing the binding location. The focus of the study is how these strategies affects the mobility (diffusion coefficient) of a tracer particle. The main result of this thesis is a graph showing the diffusion coefficient as a function of the binding rate for different binding strategies and particle densities. We provide analytical estimates for the diffusion coefficient in the unbinding rate limits which show good agreement with the simulations.Hur "trĂ€ngsel" (frĂ„n engelskans "crowding" t ex molecular crowding) pĂ„verkar diffusionsprocesser Ă€r viktigt inom mĂ„nga olika vetenskapliga omrĂ„den. Forskningen som för tillfĂ€llet utförs strĂ€cker sig frĂ„n rent teoretiska berĂ€kningar till experiments dĂ€r man kan följa enskilda proteiners rörelse i en cell. Ăven fast Ă€mnet Ă€r viktig och vĂ€l undersökt finns det fortfarande mĂ„nga aspekter som man inte förstĂ„r till fullo. I det hĂ€r examensarbetet beskrivs en Monte Carlo metod (Gillespie algoritmen) för att studera hur trĂ€ngsel pĂ„verkar en partikel som diffunderar i ett "nĂ€stan" en-dimensonellt system. Det Ă€r nĂ€stan en-dimensionellt i det avsedde att partiklarna diffunderar pĂ„ ett gitter men kan binda av frĂ„n gittret och binda tillbaka i ett senare skedde. Olika metoder för hur partiklarna binder till gittret undersöks: Ă
terbinding till avbindingsplatsen och slumpmÀssigt vald Äterbindingsplats. Fokus ligger pÄ att förklara hur dessa pÄverkar mobiliteten (diffusionskonstanten) av en spÄrningspartikel (tracer particle). Resultatet Àr en graf som visar diffusionskonstanten för spÄrningspartikeln som en funktion av avbindingsfrekvens för olika bindingstrategier och partikeldensiteter. Vi ger ocksÄ analytiska resultat i grÀnsvÀrdet för höga och lÄga avbindingstakter vilka stÀmmer bra överens med simuleringar
