Utvärdering av Near Field Communication och Certified Wireless USB: Säkerhet vid utveckling av applikationer
Today?s society is one where technological advances are made daily, which
increases the need to stop and assess the risks against users? integrity when
integrating new technology in contemporary systems all the greater. We have
taken two technologies, Near Field Communication and Certified Wireless USB,
whose envisioned area of use is to be integrated into mobile phones, and
evaluated what security threats are revealed for the respective technologies.
The threats against security have been identified through research of the
standards and existing reports for each technology. Practical experiments have
not been conducted on account of us not having access to any equipment to run
such trials.
Basel II och fastighetsbranschen - en scenariostudie av de nya kapitaltäckningsreglernas konsekvenser för fastighetsbranschen
Banks carry a great responsibility when it comes to the financial systems in our society. Disturbance in the credit system affects both lender and borrower. All financial institutions must therefore carefully estimate their risk exposure. This assessment enables them to cover themselves from losses with appropriate capital buffers as main guardian. In order to prevent bank crises and also to maintain financial stability in general, new regulations concerning analysis and preventive actions were introduced on the 1st of February 2007.
Mentorers betydelse, funktion och nytta för elever i gymnasieskolan : En narrativ studie kring mentorer och mentorskap utifrån ett elevperspektiv
The study describes six upper secondary school students? thoughts of and stories about mentors and mentorship in secondary school. The mentorship has been studied with a hermeneutic approach from a narrative pupil relational perspective, which is influenced by the phenomenological humanity perspective. The aim of this study is to describe a few pupils? life worlds and to try to interpret how they describe and explain their own behavior related to mentorship and their mentors.
Differences in host plant preferences and olfactory physiology between populations of the moth Spodoptera littoralis established in Egypt and Benin
This study was made to compare and distinguish any differences in olfactory recognition and
host plant adaptation between two strains of cotton leaf worm, Spodoptera littoralis. The
populations used were established in Egypt and Benin, Africa. The documentation consisted of
information about (1) each of the strains development through the larval stage up to pupation on
diets of cotton, clover and cowpea. (2) Their oviposition preferences as adults between cotton,
clover, cowpea, maize and cabbage. (3) Electroantennographic recordings to quantify any
possible responses to plant volatiles.
Throughout the diet experiments the larvae from the Benin strain showed significantly a better
development between artificial, clover, cowpea and cotton respectively, while the Egypt strain
had significance between artificial, cotton and cowpea/clover as diet.
Also noted was how the strains substantial development of weight differentiated if fed the cotton
diet, followed by the cowpea diet showing that the Benin strain would develop a higher body
mass on a cotton diet as well as on a cowpea diet.
This trend was however switched once the pupal stage was reached, where the Egyptian strain
contained a significantly greater body mass than the Benin strain on the artificial and the Benin
strain a greater on cowpea, which suggests that in the end, the Benin strain develops significantly
better on cowpea while the Egypt strain develops better on an artificial diet.
During the oviposition experiment that both stains showed a clear difference in hierarchy of host
plants considered suitable for oviposition, where the Egyptian strain is significantly more
attracted to clover than the Benin strain.
Also showed with electroantennographic recordings and significant values was the higher
Sensitivity the Egypt strain had towards (E)2-hexenal, (E/Z)-b-ocimene, (Z)-3-hexenyl acetate,
Nonanal, (-)-linalool and ?-myrcene when compared to the responses from the Benin strain..

Solenergi och värmelagring i kvarteret Lagern
Humanity stands before a huge challenge to lower its emissions of carbon dioxide and its use of energy at the same time as the global population is rising and the developing countries are being industrialized. A lot of newly built buildings are due to this challenge, designed to be more energy efficient but also use renewable energy resources instead of pollutant fossil fuels .Solar energy is one of the purest forms of energy that exists in abundant amounts, which is why it is most likely that it could come to play a major part in the future energy market. The main purpose of this report is to investigate the possibility to implement a sustainable energy system with solar thermal heat and heat storage as main sources of energy in the neighborhood ?kvarteret Lagern?, which is the area where the old football stadium ?Rasunda Stadion? was located. New developments within different heat storage techniques have opened up new approaches to enable buildings an all year round heat supply from solar energy. This report will focus on heat storage in boreholes. At the present here is only a preliminary plan of how the neighborhood is supposed to be designed.
Studie om individers kontrastkänslighet och preferenser för horisontell och vertikal belysningsstyrka
The purpose of this study is to survey and evaluate if the individual contrast Sensitivity and preferences for horizontal and vertical lighting level correspond to the values that standard SS-EN 12464-1 recommends for the workplace- and surrounding light levels.This study examines if lighting should be adapted after the individuals? need or if a general value can be found that will cover every individuals? need for a workplace and surrounding light level. This study also examines if parameters like sex, age and/or glasses/lenses have an effect on the amount of lighting that the test subjects need. Lastly we compared the values concerning the relationship between workplace- and surrounding light levels with standard SS-EN 12464-1?s recommendations.The study is carried out with an experimental design that surveys 220 test subjects who were chosen by a selection of convenience.
Fonologisk bedömning baserad på bildbenämning jämfört med spontantal av barn med fonologisk språkstörning
In a phonological assessment, the aim is to obtain systematic and reliable data of a child's speech output, which can then serve as a basis for a decision on an appropriate intervention (Wolk & Meisler, 1998). Whether phonological assessment should be derived from an analysis of picture-naming or a conversation with the child, and whether the two methods for elicitation generate equivalent results, has been debated among clinicians and researchers for an extended time (Masterson, Bernhardt & Hofheintz, 2005).The aim of the present study was to compare two methods of speech elicitation for phonological assessment: spontaneous conversation and picture-naming, respectively. In the study, the procedures have been used when assessing children with phonological disorders as well as children with typical language development. The results are presented using two levels of phonological analysis; degree of phonological impairment, in terms of percentage of phonemes correct (PPC), and type of phonological impairment, in terms of phonological simplification processes. Eighteen (18) children participated in the study, nine (9) with phonological impairment (age 3;10 ? 5;11), and nine with typical phonologic development (age 3;2 ? 4;6).
Moder och modern? : Svenskkyrklig mariologi och synen på kön och kyrka 1920-2010
This study deals with questions about male and female, power and church, related to the Mariologies of three prominent leaders in the Church of Sweden in the last century: Erling Eidem, Paulina Mariadotter and Cristina Grenholm. The mentioned topics are important for conservative High Church people as well as for radical feminists, and they are therefore necessary to address in the context of discussions about the church´s identity and the search of greater unity.Each Mariology is related to contemporary ideas about the relations between male and female, and to the tradition of the church as the leaders themselves see it. During the years 1920-2010 the relations between the sexes changed a lot as a result of the impact of modernity, which also affected how people perceived the relationship between the individual and the tradition/authorities. The present study concludes that there is a connection between Mariology and contemporary ideas about male and female. However, the Mariologist´s attitude to the tradition of the church seems to decide which perspective is allowed to dominate.

IT gives the ability to compete and could also be a condition for many to be able to compete. In different businesses it could vary in where they put their focus when they choose an IT investment. This thesis examines how the purchase process of IT looks. How does processes differs in a bigger company versus a smaller company? From these two perspectives this study examined these research questions: Who makes the decisions whether or not an IT solution should be purchased? What aspects decide when companies are to choose between different IT solutions? Where in the purchase process do problems usually emerge?Purpose: The purpose of this thesis is to describe and analyze the purchasing process of IT from a business perspective.
Ekonomi vid uttag av långa toppar som skogsbränsle i slutavverkning :
The market for biofuels from the forests have had a positive development and the job initiators for this master´s thesis wanted to examine the profitability of a method for harvesting forest fuel, which was unfamiliar to them. The method was the ?long tree tops-method?, here called the LT-method.
The LT-method is characterised by the fact that timber is harvested as the only roundwood assortment while the rest of the stem, which in other cases would become pulpwood, is harvested as forest fuel together with the logging residues. The method is based on the assumption that advantages in handling of the forest fuel assortment such as increased load weights for forest hauling and truck transportation, should compensate for the lower price for pulpwood when sold as forest fuel.
The aim of the study was to compare the profitability of the LT-method with the GROT-method (harvest of timber, pulpwood and logging residues) and conventional logging without any harvest of forest fuel, and aslo to try to identify factors affecting the profitability of the different methods.
Riskfaktorer för förlossningsdepression samt förebyggande åtgärder ? En litteraturbaserad studie
Introduction: Approximately one in eight women suffer from postpartum depression, which can affect them for a period of weeks or even years. Postpartum depression does not only affect the mother, it also has a negative influence on the rest of the family. Postpartum depression can also lead to negative consequences for the development of the infant. It is an illness that is still considered a taboo, a fact that makes it hard to identify among women who are affected. Aim: The aim of the study was to examine cases where there is a connection between social economic status (SES) and the presence of postpartum depression.
Development of real-time RT-PCR for the detection of human sapovirus in foods
Food-poisoning is a major health problem and an estimated half a million Swedes are food-poisoned annually, with acute gastroenteritis as a consequence. One of the major causes of contaminated foods is related to food- and waterborne viruses. To be able to trace back the source of contaminant, the method of detecting viruses must be specific and sensitive. No standardized method for detecting foods for sapovirus exists today.
The aim of the work described in this bachelor thesis is to implement and opti-mize a real-time RT-PCR method for the detection of all genogroups of human sapovirus in foods.
