Denna studie syftar till att se på hur barn tar sig an konstruktionsritningar i jämförelse med fritt byggande i en lekfull gruppmiljö. Tidigare forskning visar skillnad mellan mängden män och kvinnor i tekniska yrken och även män och kvinnors inställning till de tekniska ämnena. Vissa forskare visar också på åldersskillnader mellan hur barn lär sig tekniska ämnen. Tar fyra- och femåringar frivilligt sig an konstruktionsritningar, följer dem och färdigställer de konstruktionen? Studien har särskilt tittat på om det fanns skillnader mellan flickorna och pojkarna när de byggde? Hur påverkar barnens eget intresse hur de bygger? Om barn, fyra och fem år gamla kan följa bygginstruktioner?Resultatet av denna studie, i viss mån, stödjer tidigare forskning om att det finns en genus aspekt redan i förskoleåldern, pojkarna var mer försekomna och hade lättare för att följa lego instruktioner än flickorna, men frågan kvarstår; varför finns denna skillnad? Förutom genusaspekten fanns det också ett tydligt resultat som visade på skillnad i byggkunskap mellan fyraåringar och femåringar.

The purpose with this project is to explore and verify three renovating systems for Miljonprogrammet (common expression forbuildings constructed during the years 1965-1975 when over a million houses where built in Sweden) to take measure to thelargely transmission losses of these buildings. Many of the buildings from this period have similar constructions and thereforethe same techniques can be used to renovate several of them. This project only considers the climate scale, although thereare many more factors to concern for to efficient the buildings of Miljonprogrammet.This thesis presents examples of renovations carried out using two of the three renovation systems.The essay presents a reference house of choice on which we apply the three systems and calculate the new U-values,consumption of energy and the investment costs. The new U-values the building is given is matched to the values ofrecommendation for passive houses. Our reference house is a two story apartment building, located in the village ofLammhult, with brick facades at the ends and plaster at the long sides.

Baron Carl Adam von Nolcken was born in 1811. In 1834 he took over Jordberga Estate in the South of Skåne from his father. The estate remained in his possession until his death in 1857. von Nolcken was interested in agriculture and horticulture from an early age and attended the newly started Institute of Agriculture, Degeberg in Västergötland in the early 1830:s. At Degeberg, von Nolcken learnt all about modern farming methods, which he put into practice on his own estate. von Nolcken was one of the persons who during the mid 19th century worked intensely to develop horticulture and the art of gardening in Skåne.

Researchers at Karlstad University have developed a method for making paper ion conducting. The reasearchers want to test this technique in various applications and produce products that make use of the ion-conducting paper. Hopefully this will drive the development forward and result in new applications for the ion-conducting paper.This study was to test the possibility of manufacturing a gas sensor of conducting paper along with electrodes of conductive polymers printed on the paper. By comparing the paper sensor with an electrochemical cell in which the electrodes of conductive polymer replaces electrodes of metal and ion-conductive paper replaces the liquid electrolyte in the electrochemical cell, it was hoped that it would be possible to measure the oxidation and reduction reactions that a gas could introduce at the electrodes.It was shown that it is possible to measure a potential difference in the range of 0.3 V to 0.5 V between the electrodes when exposing an electrode to 100% oxygen. The reaction that takes place is relatively slow and the reaction rate is partly due to the distance between the electrodes.Since the sensor can measure oxidation and reduction reactions it is possible that, in further development of a sensor, the sensor can be made ??into a versatile sensor with more applications than gas measurement as there are many more ways to oxidize or reduce the electrodes than by exposure to oxygen.During the study there have been discussions and meetings held with various companies in the sensor industry to be able to specify what the market demands of a sensor made ??of paper and the requirements that must be placed on the sensor for it to be interesting for the companies..

We follow Torsten Brodén through his writings on Russell's Paradox. By comparing his work to that of his fellow colleagues at the time, we acquire an understanding of the context in which he wrote. Brodén is somewhat unique among contemporary mathematicans in his philosophical approach and thorough treatment of the most fundamental logical building blocks of set theory. With this mindset, he considers Russell's Paradox from a new point of view and believes himself to have successfully found a way to rid the world of it..

Several cities have implemented various projects to improve traffic safety in city centers.During 1970s and 1980s the city centers changed as the suburbs grew and large shopping centers were located outside the center. At the same time, several projects were initiated with construction of pedestrian streets and restriction of traffic in the center. In year 1994,shared-used areas were introduced in Sweden and these areas are often used in center environments.In Sweden, municipalities are responsible for integrating security in public places and in comprehensive plans and detailed development plans. The National Board of Housing,Building and Planning is the authority for administrating planning issues and develop general guidance about planning. Traffic is one of their key issues, although today there are no concrete guidelines from the National Board of Housing, Building and Planningfor the design of traffic safety in city centers.Traffic safety in city centers affects many people because the city center is a public place.It is therefore important that there are current guidelines available that are helpful for changes and improvements in traffic safety in the city center.The purpose of this report is to formulate guidelines for planning city centers from a traffic safety perspective.

Finnhamn is a group of islands that are located in the middle north part of Stockholm?s archipelagos. On the main island Stora Jolpan there is a camp called Sommargården, which consists of eleven different buildings in various sizes. The assignment given by the Archipelago foundation (Skärgårdsstiftelsen) is to analyze if it?s benefited to replace Sommargårdens current heating system that consists of electricity radiators, with a more energy efficient heating system. This research is done with help of the literature review and a visit to Finnhamn in order to map Sommargården?s current state and its energy usage.

The aim of this work is to give a broader and more nuanced picture of the use of locks and keys during the Iron Age, in particular the late Iron Age, in the Lake Mälaren region. This has been done by comparing two buildings: the hall on Helgö and the living quarters in the garrison on Birka. Here we can see two very different areas where locks and keys were important parts of the daily life. The study also includes a typology of padlocks based on the findings from the same places as the building study and their surroundings..

Spectacular buildings and categorized districts are becoming more common elements in cities. In many cases, they are the result of city branding, which means choosing a city image and dealing with it like a brand to profile and compete against other cities. This essay study what impact on and roll in urban planning the trend might have. The first part relies on literary studies and describes what has been written about city branding. The globalization, the experience economy, urban management, urbanization and the theory of the creative class are pointed out as driving forces of the popularity and the spread of city branding.

Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.

This project is a step towards automatic firefighting. The goal is to decrease the number of personal injuries by replacing the human firefighter with robots or similar technical tools. Especially in very hostile environments due to risk of explosions or building collapse. A robot is easy to replace and can be maneuvered from a safe distance. The idea of the project comes from the company Drones Networking which aims for developing a totally autonomous firefighting system.

I samband med att datorstödda ritningsprogram introducerades i byggbranschen, effektiviserades utformningen av ritningar. Tekniken innebar att tidigare metoder med att rita för hand delvis bibehölls, fastän ritningarna utfördes på datorn. De senaste åren har byggbranschen påbörjat en ny förändring avseende framställning av handlingar, med användning av Building Information Modell (BIM). Med denna metod skapas en modell i 3D över byggnaden och dess omgivning. Modellen snittas i planer och sektioner, vilka utgör traditionella ritningar i 2D.

Due to the climate change natural disasters expects to increase and in some areas the conditions for dissemination of hazardous pollutants from contaminated areas could be affected. Different inventories and mapping has been made to identify areas of risk for flood or avalanche around the country. At the same time inventory and treatment of potential polluted areas (MIFO objects) is progressing. In Ljungans run of area in Västernorrlands county is a exposed area due to the amount of clay and silt in the ground that are sensitive in the context avalanche. The area has also a lot of MIFO objects and risks of flood.This essay aims to investigate what data material that is available regarding MIFO objects, flood- and avalanche risks in Ljungans run of area in Västernorrlands county.
