Momentbärförmåga för semikompakta ståltvärsnitt av HSQ-balkar : En modell för interpolering mellan eurokodens klass 2 och 3
The current standards for design of steel beams are divided into four classes based on the slenderness of cross-sectional parts. Depending on the section class a beams load capacity is either determined by a plastic, elastic or a reduced elastic model. The division between cross-sections calculated by a plastic and an elastic model is today done in a very harsh way with no smooth transition. This leads to a large difference in the calculated resistance for the sections located near the class limits. Elasto-plastic sections are in the current situation calculated as purely elastic and their large plastic reserve is not considered in the current standards.
Kan markfuktighetskartor användas för att hitta skogsmark med hög bonitet? : ett gis-baserat försök med dtw-index och laserskannad övre höjd
The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). The belief of such an assumed relationship was based on knowledge that the ground water level is related to site properties that can either promote or impede tree growth.
Data primarily comprised rasters of the Krycklan catchment in northern Sweden and depicted DTW-index and a laser scanned vegetation height. The 100th height percentile of each pixel in the vegetation raster was assumed to mirror the top-height, letting it act as a relative measure of SP within a delineated area of equal stand age.
Jag har kompetensen! : Hur ett antal klasslärare resonerar kring och upplever sitt arbete med elever med läs- och skrivsvårigheter/dyslexi i undervisningen
The aim of this work is to examine how a number of class teachers reason about and find their work while teaching students who have reading and writing difficulties / dyslexia. The empirical study was intended to answer the question based on three questions.The work is based on a qualitative method as empirical material gathered in semi-structured interviews. Six classroom teachers, one male and five female teachers were interviewed. The interviewees were from six different schools in Stockholm Municipality and were between 27-61 years old.Most of the classroom teachers feel that there are approximately 4-5 students with reading and writing difficulties / dyslexia in each class. Half of the teachers feel that students with dyslexia may be different as they are quiet, unsecure and shy.
Utvärdering av liggbåsinredningar för bättre välfärd och hygien hos mjölkkor
The dry period is usually 6-8 weeks and in this period the basis of the performance in the following lactation is settled. In an average herd about 15% of the cows are dry (Marcussen & Krog Laursen, 2008). In many herd the dry cows are set aside, that means setting aside 15% of your herd, at the time when they are preparing for their next lactation. The recommendation for number of groups differs depending on country traditions or reasons for grouping. If you look at recommendation for feeding, some companies selling feeding equipment advocates one group throughout the dry period, but the number differs from one to three.
Vem är det framför skärmen? : En fördjupad textanalys om hur svenska politiker konstruerar jag-bilder på Twitter.
The trend of social media is a global hit and now both individuals, businesses, celebrities and politicianshave their own social media pages, which means that the visibility increases and focus lies on what'swritten and published by the person. Mediated communication are everywhere around us and affects theway we communicate with each other and also the way we look at ourselves and most importantly how weportray ourselves. The individual's perspective has become a relevant issue with the rapid moderndevelopment. One's cultural identity can be seen as a life-long project.The purpose of this paper is to do an in-depth text analysis to examine how Swedish politicians constituteand construct identities, with a focus on "the self" and the "mediatization self" on the micro-blog Twitter.The theoretical ground for this study is from a discourse analysis point of view that focus on ?the self? andthe ?meditization self?.
Den stressade eleven : En enkätstudie om stressorer som utsätter barnen för stress
Researchers claim that stress has become a word of fashion and is now frequently used. They also state that there is no accepted definition that can easily describe the concept. In this essay, I have examined children and stress. The aim of the diploma work is to illustrate stress more closely the stress concept, the underlying reasons that can influence children and how teachers and school staff support children in their stress handling. My three issues are: What is stress? What stressors put children, at home and at school, in a stress situation? How can teachers help children to manage their stress? The diploma work is based on a literature study in order to find out what has been written on the subject in earlier research.
Däck-mark Interaktion hos skogsmaskiner
The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.
"Var är Emma!?" : En essä om integrering av barn med problematik i skolan
This essay contains two stories that reflect the reality I face as an educator, as well as a reflective discussion about my self-perceived dilemma. The dilemma reflects a classroom situation where I as an educator have trouble dividing my focus, my focus is either put on entire the class or on the child with special needs. Through this self-perceived situation I have started to question how children with special needs find their place in the school today. I discuss how I can handle and look at the unique situation that occurs when meeting this child.Terms like integration, inclusion, segregation, social rights and the expression "a school for everyone" will be discussed in this text, as well as how we can connect these terms and expressions to the problems I find in the school system?s way of handling children with special needs.I also highlight my dilemma from different ethical perspective.
VART LEDER EN BRO AV POESI? ?Jo, jag g?r i f?rskoleklass och jag kan skriva dikter.?
In autumn of 2021, the anthology A Bridge of Poetry was given to all six-year-olds in Sweden. The anthology contains both older and contemporary poetry, as well as both children?s poetry and poetry written for experienced readers. The idea is that, with the help of an adult, texts and images, and in some cases short movies, will together stimulate children?s thoughts and initiate conversations, as well as arousing children?s curiosity about poetry.
Klimatpåverkan vid vägbyggnad -beroende av vald konstruktion
It?s a fact that the climate is affected by the vehicle that runs on the worlds roads. But theconstruction of the road itself is rarely thought of as a climate threat. Svevia and the Swedish roadadministration have opposite views of how the construction of roads should be carried thru. It?sthe difference between those two construction methods that is the base in our thesis.The amount of energy use or the emissions are not analyzed for neither the Swedish roadadministrations nor Svevias construction models.
Delaktighet i samtal inkluderar elever med särskilda behov : en jämförande studie mellan ordinarie undervisning och specialundervisning
This study is about how the dialog can help students with special needs to feel participation and inclusion in the class and the teaching. My purpose with this study was to look for how the students with special needs interact with other students and teachers through the dialogue. I also wanted to know if there is any positive and negative effects to teaching students with special need in the classroom compared with the teaching at the special teacher.I have taking purpose of the sociocultural theory in my study because it says that children learn together when they communicate with each other. The theory central words are dialog and scaffolding in the zone of proximal development. I also describe central words like participation, inclusion and students with special needs in the special teaching.I have investigated in four interviews, two of them were with a teacher and a special aids teacher, and two of them were students with special needs.
Objektdetektering i SAR- och IR-bilder
This report treats detection in IR-pictures taken from airplanes over the ground. The detection is divided in two parts. First there is a detection with filterkernels with the task to point on targets and objects that look like targets. The second part is a discriminator that demands more calculations and has the task to sort out the false alarms from the discriminator. Both the detector and the discriminator contain thresholds thats been trained from trainingsets of data.
Matematik - Språk och kommunikation : En jämförande studie i en internationell skola
The purpose with this essay is to compare two classes in an international school during their mathematic lesson. The international school offers education to their pupils in two languages; in Swedish and in English. Through this study I want to find out how teachers are working with language and communication during school hours. I will compare the work of two teachers and two classes to find out the differences and similarities between their work methods concerning language and communication during mathematic lessons.The main questions for the essay:How do the teachers work with language and communication in this school during the mathematic lessons?What similarities and differences are there between the two teachers in matter of methods of working with language and communication during the mathematic lessons?The research is based on interviews with the teachers and also on observations in the classroom during mathematic lessons.
Naturljud inomhus - En pilotstudie i tre fall
It's an everyday experience shared by many that nature can be of help in relieving pain, reducing stress, support mental recovery etc. In the last three decades or so this experience has also found support in a large number of scientific investigations. Among other things the experience of nature has been shown to reduce stress and pain in patients and to boost concentration and reduce impulsive behavior in children. Most of this research however has mainly been concerned with the visual modality. In this thesis the aim has been to focus on the auditory modality in this context by trying to reveal some effects on people from the exposure of nature sounds played indoors in three different environments: a grammar school class room, a kindergarten play room and a post-surgery wake up room at an intensive care unit.
Funktionsentreprenad för beläggning och vägmarkering
This report is written in cooperation with the Swedish National Road Administration South-Eastern Region in Jönköping. The report is a result of the evaluation to give an answer to the question about how well the function contract has been carried out on the E4 in Östergötlands and Jönköpings län. The evaluation is divided in two hard parameters and one soft.The Swedish National Road Administration is interested in knowing how the standard on the road have been changed during the functions period, which is the reason why the first hard parameter is considering road standard. To evaluate the standard there have been a comparison of values from measures taken every year on the current road stretch. The second hard parameter considers economy.
