Complexation of o-phthalate (1,2-benzenedicarboxylate) at the water-boehmite (gamma-AlOOH) interface has been studied in 0.1 N NaCl media at 298.2 K within the range 4.0 < pH < 10.0. Equilibrium measurements were performed as potentiometric titrations and adsorption measurements. Attenuated total reflectance IR spectra were recorded to obtain structural information of the phthalate surface complex

In order to estimate the detention effect (storage and peak flow attenuation) of a sedum green-roof, a comparison between the response of an impervious roof (runoff coefficient C = 1) and a green-roof has been carried out. Precipitation and runoff data from several controlled experiments (with wet initial conditions, i.e. approximately at field capacity) on a sedum green-roof were used for the ana

Single nucleotide polymorphisms (SNPs) are the most common form of genetic variation in humans. The number of SNPs identified in the human genome is growing rapidly, but attaining experimental knowledge about the possible disease association of variants is laborious and time-consuming. Several computational methods have been developed for the classification of SNPs according to their predicted pat

Att öka förståelsen av sina kunder har utvecklats till en allt viktigare uppgift för dagens företag. För att få bättre kunduppfattning utvecklas i detta examensarbete ett nytt mått som bedömer kundinformation. Ett allt vanligare problem för affärsverksamheter är att försäljnings- och marknadsföringskostnader ökar. Detta beror på att dagens kunder har alltmer olikartade köpbeteenden. För att kunna Customer segmentation and target analysis are two essential tasks when identifying a company’s customers. To perform these tasks, this thesis develops and applies hybrid data-mining models, integrating clustering and decision trees. The hybrid models are applied to the life-logging camera company Narrative, in order to gain insights into their customer data. From previous research, we found that t

This Master Thesis will cover the development of the mechanics and design aspects for a new product innovation made for IPsense AB (at Lund Technical University and Ingvar Kamprad Design Center in Lund, Sweden). Due to the sensitivity of the project some information has been left out. The product is part of an IP-based network concept developed for analyzing sound in real time. The total concept

Distribution as a concept means that a task (for example, data storage or code execution) is parallelized on multiple computers. It goes hand in hand with the concept of big data – extreme amounts of data that can’t be processed by a single computer. Because of this, the most established tools for distributed parallelization is tools that are designed to handle big data. This thesis explores wheth

There is a constant need for the fire and rescue service to develop new methods, materials and extinguishing media to implement the most effective firefighting operations as possible while minimizing environmental impacts. The effect of additives in the extinguishing water is fairly unknown. In this report small-scale experiments shows that additives and fire retardants can provide a significant i

Cardiovascular diseases are currently the leading cause of death in the world, which killed nearly 17 million people in 2011. For this reason, research in Cardiovascular diseases are of the up-most importance. In this thesis, real-time Cardiac Magnetic Resonance Imaging data is used to create simulated cardiac cycles for multiple phases of the respiratory cycle. By exploring image classification o

A selection of well known period luminosity relations for cepheid variables are studied under the assumption that cepheid variables have a mean vertical velocity of zero in the galactic plane. Proper motion data from Hipparcos and Thyco-2 catalogues are coupled with the distances obtained from applying the period luminosity relations on a database of known classical cepheids to calculate the veloc

Convolutional neural networks have in recent years been successfully employed for various image processing tasks, such as filtering noise. There are however relatively few published attempts for processing video in this way. Image processing methods on single images can be applied frame by frame, but often fail to consider continuity and flow between frames. In this master's thesis we construc

This paper examines factors that triggered widespread currency and banking crises in Latin America during 1990-2010 by looking at specific macroeconomic and financial variables. The paper aim to contribute to the vast literature of financial crises by distinguishing itself in three ways. First, the paper implements a dynamic binary choice panel data model with fixed effects. The binary choice mode

The purpose of this study is to analyze how the child’s perspective is used in social services today and how the usage of the child’s perspective is expected to change due to the incorporation of the convention on the rights of the child. We collected data through qualitative interviewing with six participants from the same social service office. In our study we have established that the concepts

Abstract Author: Erica Almström Title: “Too personal a tale” – a qualitative study about accommodation educators vision of their work with unaccompanied refugee children. Supervisor: Anders Östnäs The purpose of this study was to illustrate how the work with unaccompanied refugee children is perceived by the employees at a youth accommodation. The study had a qualitative study and the empirical d

Let us talk about the kids – family law social workers’ description of mediation with separated couples Divorce and separation are a part and parcel of modern family life in western society. However the separation process can sometimes get out of hand, especially when children are involved. Long custody fights in the courts are not only harmful to the children but are also costly for society. Med
