Privacy preserving neighborhood awareness in vehicular ad hoc networks

Location information is exchanged among members of Vehicular Ad Hoc Networks (VANET) to serve many road and safety applications. Vehicles will announce their identity, position, and mobility information to their neighboring nodes. The importance of such information makes privacy a major concern. Successful implementation of VANET requires protecting the vehicle's identity at all times and preventi

Energy use and carbon emissions: From decoupling and transitions to sufficiency?

The paper examines and illustrates different trends in relation to historical energy use-related intensities and corresponding CO2 emission trends. The methodology encompasses a decomposition quantitative approach for estimating decoupling trends to energy use and economic and demographic parameters driving CO2 emission levels. The analysis covers both global and regional trends for the period 197

Childhood Health and Labor Market Outcomes in the Case of Type 1 Diabetes

This study investigates the impact of childhood health on labor market outcomes. We used type 1 diabetes as an instrument of health because its cause is multifactorial and it is triggered by a complex combination of genetic and environmental components; its incidence is low and unforeseeable for the individual; and its onset may be considered an exogenous health shock. Using data from the Swedish

Mobility of older women and men at transition from a two person household to a one person household

This study reports on a study from 2008 of overall mobility patterns among older people and the mobility patterns of those in transition from a two person household to a one person household. The purpose of the study was to explore the mobility patterns of those in transition from a two-person household to a one-person household in relation to the overall patterns of mobility of the older people.

Interaction effects in the transport of particles in nanowire quantum dots

Interactions between physical bodies constantly affect their properties. This thesis presents a theoretical study on the effects of interaction in few-body nanowire quantum dots. The focus is to a large extent on a phenomenon called Wigner localization, and how this, as well as other interaction effects, can be identified in an experiment by transport spectroscopy and by thermopower measurements.

Antimonide Heterostructure Nanowires - Growth, Physics and Devices

Abstract in UndeterminedThis thesis investigates the growth and application of antimonide heterostructure nanowires for low-power electronics. In the first part of the thesis, GaSb, InSb and InAsSb nanowire growth is presented, and the distinguishing features of the growth are described. It is found that the presence of Sb results in more than 50 at. % group-III concentration in the Au seed partic

Optical Characterization of III-Nitride and II-V Semiconductor Nanowires

The optical properties of III-V semiconductor nanowires for optical devices have been investigated by photoluminescence spectroscopy, cathodoluminescence spectroscopy and cathodoluminescence imaging. The material systems that have been studied include the nitrides (InN, GaN and AlN) and ternaries, and a few common phosphides and arsenides. Due to the different optical properties of the materials,

Aerotaxy - A Gas-Phase Nanowire Growth Technique

In this thesis an efficient nanowire fabrication technique, called Aerotaxy, is investigated. Traditional nanowire fabrication techniques include the use of a substrate as a point of nanowire nucleation which limits the amount of nanowires that can be produced per unit time. In contrary, Aerotaxy offers a continuous growth process, in the gasphase, which could substantially increase the rate at wh

Nanophotonics in absorbing III-V nanowire arrays

We have studied the interaction of light with an array of vertically oriented III-V semiconductor nanowires both theoretically and experimentally. For the theoretical studies, electromagnetic modeling has been employed. This modeling shows that with proper tuning of the nanowire diameter, the absorption per volume semiconductor material can be 20 times higher in the nanowires than in a correspondi

Molecular serum portraits - A step towards personalized medicine

Antibody microarray technology has the potential for playing a large roll in identifying serological biomarker panels for personalized medicine. The aim of this thesis, based on four original papers, was to investigate if information in the serum proteome could be extracted and used for diagnostic, classificational, prognostic or treatment predictive purposes in a range of diseases. In two studies

Engineered Nanoparticles Generation, Characterization and Applications

It is predicted that novel nanometer-sized structures incorporating nanoparticles will have a considerable impact on our lives during the coming decades. Engineered nanoparticles are already found in a number of commercially available products. However, many applications of these nanoparticles have only reached the stage of promising ideas or research demonstrations. The number of nanoparticle-bas
