This thesis investigates the relationship between the demographic dividend and institutions. The aim is to make an attempt of attaining further knowledge about the requirements for obtaining a demographic dividend. This is done through the comparison of Asian countries and South American countries. The obtained results confirm the positive effects of an increase in the working-age population relat
Planar antennae have become very popular owing to their relative ease of manufacture and unobtrusive nature (they are conformal to surfaces) especially with regard to certain devices such as smart phones, watches and fitness gadgets. Although the fractional bandwidth of planar antennae is small, the actual bandwidth in absolute terms is high owing to the higher centre frequencies used and proves u
In this thesis the effects of innovation on employment, at industry level, for the Brazilian economy are investigated. Merging data from Innovation Surveys, Industrial Surveys and the National Account System, a panel of 22 economic sectors was constructed. The main empirical results indicates that demand factors has positive and significant effect on employment while product innovation has a negat
In this thesis, the mechanical properties of thin films of low density polyethylene were investigated. There were three main objectives: to perform experiments, to simulate the experiments in Abaqus and to identify material parameters for some constitutive models by optimization. The experimental part consisted of conventional uniaxial tensile tests. Another objective was to investigate whether th
The use of artificial intelligence tools is rapidly increasing. Companies are now looking to use AI for recruitment in order to try to ensure a more fair process. This thesis aims to answer the question “How do recruiters in the Swedish IT sector perceive the effectiveness of AI tools in mitigating bias within the recruitment process?”. While some recruiters see AI as a tool to increase object
To understand the mechanisms of economic resilience, we have studied how sectoral proximity relates to the regional capability to transform and recover from a shrinking crisis. Through a comparative study of Irish regions, a proximity analysis provided evidence that the majority of new sectors in the recovering region developed in proximity to the region’s leading sector. This leads to the conclus
To analyse the connection between kinematics and stabilizing forces related to human postural dynamics, fourteen normal subjects were investigated with posturography. Stimulation signals according to Pseudo-Random- Binary-Sequence patterns were applied to each subject. The stimulation consisted both of calf vibration and of combined calf vibration and galvanic stimulation to the inner ear. The tes
The aim of this master thesis is to develop a laboratory process that Saab Ericsson Space AB (SE) can use to demonstrate their fault tolerant computer systems at exhibitions. The process is an inverted pendulum shaped as a rocket to symbolize that the company develops fault tolerant control systems for satellites and carrier rockets e.g. for Ariane 5.
The inverted pendulum is a classical
Colloidal semiconductor nanocrystals or quantum dots (QDs) have recently attracted much attention because of their unique electronic and optical properties and potential for a wide range of applications. Near-infrared (NIR) PbS QDs were synthesized using oleic acid (OA) as a surfactant for stabilizing the nanocrystals. PbS QD’s of different diameters were obtained by varying the injection temperat
Several founding democratic norms of the European Union (EU) may nowadays be found in their emerging stage in the post-Soviet countries outside of the Union’s borders. This is an indication that norms may get diffused, float around the continent and find a fertile soil in a new environment. Thus Georgia, located thousands of kilometers away from the EU, is highlighted as a success story of its coo
Happiness research generally claims that money is not important for happiness. Money is often studied by happiness economists in the form of income. However, there are reasons why income can be considered an imperfect measure of economic well-being. For example, it does not account for wealth or even consumption—and this is just to cite strictly economic examples. There are also other aspects of l
The quantum cascade laser (QCL) is a semiconductor heterostruc- ture using inter sub-band transitions to generate stimulated emission. The quantum cascade detector (QCD) is a similar to the QCL, but the heterostructure is tailored to absorb radiation and give a read-out current. In this work, three planned or realised QCL:s and two QCD:s have been simulated and analysed using a program based on th
