Active lighting applied to three dimensional reconstruction of specular metallic surfaces by polarization imaging
2005
This thesis deals with a new automated tridimensional inspection system for specular metallic surfaces, based on polarization analysis. We first present an extension of the ‘Shape from Polarization' method for dielectric to metallic surfaces. After being reflected, an unpolarized light wave becomes partially linearly polarized, depending on the surface normal and on the refractive index of the media it impinges on. Hence, by measuring the polarization parameters of the reflected light, the surface normals are computed. The ambiguity concerning the normals orientation is solved here with a new active lighting system. Then, we describe and compare numerical methods for reconstructing the trid…
Cathodoluminescence and photoluminescence study of trap centers in amorphous silicon oxynitride
2002
Amorphous silicon oxynitride (a-SiO/sub x/N/sub y/) films with different compositions were prepared using low-pressure chemical vapor deposition (LPCVD) technique, The cathodoluminescence and photoluminescence of this samples were measured from the red band to the ultraviolet band to study the trap centers in silicon oxynitride. A 1.8-1.9 eV band was found and is attributed to the oxygen and nitrogen atoms with unpaired electrons whereas the 2.7 eV band is attributed to two-fold coordinated silicon atoms with two electrons. The 5.4 eV shoulder is due to the peroxy radicals and other ultraviolet bands are supposed to due due to the Si-Si bonds.
Towards Practical Cybersecurity Mapping of STRIDE and CWE — a Multi-perspective Approach
2021
Software vulnerabilities are identified during their whole life-cycle; some vulnerabilities may be caused by flaws on the design while other appear due to advances on the technologies around the systems. Frameworks such as OWASP are well- known and are used for testing a systems security before or after implementation, and such testing is carried out against the existing system. Threat modeling however focuses on the early stages of the system design when it is feasible and easy to fix security-related flaws and prevent possible damage caused by them. For example, STRIDE is one very popular threat modeling framework. A STRIDE threat modelling specialist deals with abstract categorizations o…

Tribological properties of thin films made by atomic layer deposition sliding against silicon
2018
Interfacial phenomena, such as adhesion, friction, and wear, can dominate the performance and reliability of microelectromechanical (MEMS) devices. Here, thin films made by atomic layer deposition (ALD) were tested for their tribological properties. Tribological tests were carried out with silicon counterpart sliding against ALD thin films in order to simulate the contacts occurring in the MEMS devices. The counterpart was sliding in a linear reciprocating motion against the ALD films with the total sliding distances of 5 and 20 m. Al2O3 and TiO2 coatings with different deposition temperatures were investigated in addition to Al2O3-TiO2-nanolaminate, TiN, NbN, TiAlCN, a-C:H [diamondlike car…

Årets fester och livets högtider i Astrid Lindgrens barnböcker
2015
Tämän tutkielman tarkoitus on toimia jatkona vuonna 2011 tekemälleni kandidaatintutkielmalleni joulusta Astrid Lindgrenin lastenkirjoissa. Tässä tutkimuksessa olen laajentanut teeman koskemaan muitakin kalenterivuotemme juhlia. Yhtälailla kuin kandidaatintutkielmassani on pro gradu-tutkielmassani tarkoitus tarkastella juhlien ja juhlaperinteiden kuvausta Lindgrenin lastenkirjoissa. Samalla pyrkimyksenä oli nostaa esille sekä kirjojen välillä että kirjojen ja ruotsalaisten juhlaperinteiden välillä esiintyviä yhtäläisyyksiä ja eroavuuksia. Juhlien lisäksi tarkastelin syntymän, kuoleman ja avioliiton kuvausta lastenkirjoissa, sillä kyseiset teemat liittyvät monesti elämän käännekohtiin ja yhdi…
Barns interaktion i Astrid Lindgrens Barn i Bullerbyn -böcker och i Carina Wolff-Brandts Johanssons -böcker
2014
Tämän kvalitatiivisen tutkielman tavoitteena on selvittää, millaista lasten välinen vuorovaikutus on kirjasarjoissa, joista toinen edustaa 1940−1960-lukuja ja toinen 1990−2000-lukujen vaihdetta. Tutkielmassa vertailtiin Astrid Lindgrenin Melukylä-kirjasarjaa ja Carina Wolff-Brandtin Johanssoneista kertovaa kirjasarjaa ja analysoitiin, onko lastenkulttuuri samanlaista eri aikoina.Lisäksi tarkasteltiin lasten muuta sosiaalista toimintaa eli sitä, toimivatko lapset yksin vai yhdessä ja keskustelevatko lapset leikkien säännöistä. Tarkastelun kohteena olivat myös mahdolliset konfliktit lasten välillä. Tutkimusaineisto eli dialogit ja vastaavat vuorovaikutteiset kohdat kerättiin materiaalista läh…
Invited Article: Ultra-broadband terahertz coherent detection via a silicon nitride-based deep sub-wavelength metallic slit
2018
We present a novel class of CMOS-compatible devices aimed to perform the solid-state-biased coherent detection of ultrashort terahertz pulses, i.e., featuring a gap-free bandwidth at least two decades-wide. Such a structure relies on a 1-µm-wide slit aperture located between two parallel aluminum pads, embedded in a 1-µm-thick layer of silicon nitride, and deposited on a quartz substrate. We show that this device can detect ultra-broadband terahertz pulses by employing unprecedented low optical probe energies of only a few tens of nanojoules. This is due to the more than one order of magnitude higher nonlinear coefficient of silicon nitride with respect to silica, the nonlinear material emp…
