Image registration is the process of geometrically aligning two or more images. In this paper we describe a method for registering pairs of images based on thin-plate spline mappings. The proposed algorithm minimizes the difference in gray-level intensity over bijective deformations. By using quadratic sufficient constraints for bijectivity and a least squares formulation this optimization problem

The adsorption of methylene blue (MB) onto zirconium phosphate (ZrP) was studied and the adsorption capacity value and isotherms were determined. The adsorption capacity of ZrP was increased after being exposed to gas phase n-butyl amine. The adsorbed MB on ZrP was used as a modifier material in carbon paste electrode (MCPE), which in turn was used in voltammetric investigations and flow injection

Popular Abstract in Swedish De senetruskiska votivhuvudena i terrakotta (bränd lera) från Tessennano på Medelhavsmuseet i Stockholm hittades 1956 i anslutning till en lantlig helgedom, ungefär tio mil norr om Rom, Italien. Att de är votivgåvor innebär att de skänktes av tillbedjare som representationer av dem själva inför gudomen eller gudomarna. Avhandlingen diskuterar emellertid inte de religiösThe Late etruscan terracotta votive heads from Tessennano were found near a rural sanctuary about a hundred km to the North of Rome in 1956. Whereas the facial fronts are serially produced with moulds, the backs are handmade. By using not only the moulded and the handmade features but the raw material (clay and temper) as well, it has been possible to make suggestions as to how, when and where the

The first three US Presidents of the century have, to say the least, had differing views concerning the nature of climate change and how this issue is addressed most appropriately – as noted by the fact that the issue has gone back and forth between being a security issue and basically disappearing from the security agenda altogether. In order to shine a light on how this has happened, this study

Natural light brings a sense of presence to the physical environment. The interaction between natural light and form puts us in connection with place in a way that can not be simulated or replaced with artificial light. This relationship has fascinated and engaged architects of all times, you could claim that the question of light and form lies at the core of architecture. It is hard to work with

The main objective of this work was to investigate if there is a contribution of aerosol from the urban region of Copenhagen at the rural station Vavihill. This was done by analyzing measurement data between 1st of January and the 28th of February 2013 measured with a Dierential Mobility Particle Sizer (DMPS), Soot Particle Aerosol Mass Spectrometer (SP-AMS), a Cloud Condensation Nuclei Counter (C

Different material is used today for packaging; all of them have different environmental problems. Depending on your perspective one material might be more beneficial than the other. In this study an energy perspective is used when looking at production of the material, the manufacturing of the package and transport of the package in its lifecycle and recovery processes. The materials studied were

This thesis compares the performance of the first-differenced maximum likelihood estimator (FDML) and the Blundell-Bond continuously-updating system GMM estimator of the autoregressive parameter in an AR(1) dynamic panel model without exogenous covariates, particularly focusing on the close-to-non-stationary case. This case is far from trivial, as a high degree of persistence is the norm rather th

In majority of academic literature related to BDSM (bondage-discipline, dominance-submission, and sadism-masochism) the focus is often centred on men and their experiences within the community. The limited focus on women and their motivations to engage in BDSM dynamics has been a driving force in this thesis. Therefore, this research aims to address this gap and explore female BDSM practitioners&#

The debate on the inclusion of women in peacebuilding has hit the scholarship field and received wide attention in the last years. There is a greater understanding of the significance from including women in the peacebuilding process. Most existing research focuses on the inclusion of women in the peace process. This thesis also took the same direction but diverged in using postcolonial theories t

Urbanisering med växande och tätare städer i kombination med klimatförändring som förväntas kunna ge extremare väder kräver ett smart markanvändande där flera funktioner kan uppfyllas på samma yta. Ett exempel på en multifunktionell anläggning är skelettjordskonstruktioner som har en bärförmåga som hanterar ovanliggande laster, skapar gynnsamma förhållanden för träd och hanterar dagvatten med reniUrbanization with growing and denser cities in combination with climate change that is expected to produce more extreme weather requires a smart land use where several functions can be fulfilled on the same surface. An example of a multifunctional facility is structural soil that have a bearing capacity to handle loads, create favorable conditions for trees and handle stormwater with purification

Denna studie syftade till hur framing-effekten påverkar minnesbilder och individers uppfattningar om en våldsam händelse, med fokus på ordningsvakters agerande. I en kvantitativ experimentell design fördelades försökspersonerna (n=63) slumpmässigt i två grupper, kontrollgrupp (n=30) och experimentell grupp (n=33). Experimentgruppen exponerades för ett negativt vinklat narrativ och kontrollgruppen The aim of this study was to investigate the influence of the framing effect on individuals’ perceptions and memory of a violent event, focusing specifically on the actions of security guards. In a quantitative experimental design, the participants (n=63) were assigned either a neutral (n=30) or a biased narrative (n=33) before watching a video of a group conflict. Participants were then asked to

Diffraction experiments with holographic gratings recorded in SiO2 nanoparticle-polymer composites have been carried out with slow neutrons. The influence of parameters such as nanoparticle concentration, grating thickness, and grating spacing on the neutron-optical properties of such materials has been tested. Decay of the grating structure along the sample depth due to disturbance of the recordi

The very bright red star HV2112 in the Small Magellanic Cloud could be a massive Thorne-A >> ytkow object (TA >> O), a supergiant-like star with a degenerate neutron core. With a luminosity of over 10(5) L-aS (TM), it could also be a super asymptotic giant branch (SAGB) star, a star with an oxygen/neon core supported by electron degeneracy and undergoing thermal pulses with third dredge up. Both T

The development of a mathematical model and a computer program to facilitate the study of the multi-cylinder paper drying process is presented. Experimentally determined values far different heat and mass transfer coefficients are used to ensure the physical validity of the model. A unique feature of the model is its inclusion of a mass transfer coefficient for the dryer fabric. Thus far, the mass

The number of applications sharing the same embedded device is increasing dramatically. Very efficient mechanisms (resource managers) for assigning the CPU time to all demanding aplications are needed. Unfortunately existing optimization-based resource managers consume too much resource themselves. In this paper, we address the problem of distributed convergence to efficient CPU allocation for ti

What is the significance of a place at the seashore? What kind of a sense of place does a place by the seashore constitute in the absence of any kind of monumental structures? Today, it is obvious within the archaeological domain that archaeological material culture is not only functional, but also acts as a metaphor for people’s self-perception. In this article, my assumption is that the differen

Utilizing semiconductor nanowires for (opto)- electronics requires exact knowledge of their current−voltage properties. We report accurate on-top imaging and I−V characterization of individual as-grown nanowires, using a subnanometer resolution scanning tunneling microscope with no need for additional microscopy tools, thus allowing versatile application. We form Ohmic contacts to InP and InAs nan
