The energy consumption continues to increase as the use of electronics and energy consuming equipment increases. The use of fossil fuels has to be phased out for this to be sustainable in the long run while the use of renewable energy continues to increase. A renewable energy source is solar energy but the production of heat and electricity are today very expensive compared to other energy sources and an important task for the solar energy market to grow is therefore to minimize the production cost of the solar collectors while increasing its efficiency to produce heat and/or electricity. One way to convert solar energy into heat is by using solar collectors and electricity can be produced by utilizing the produced heat, or by applying solar cells.This thesis aims to recommend a reflective material for the next generation solar collectors from Absolicon and to recommend a commercially available coating for the receiver tube of the solar collector. A market study has been carried out to investigate the cost-related aspects along with the optical and durable aspects for the optical material of the solar collector.

The thesis strives to answer the question whether there are any differences between how young customers, in comparison with older, are affected by brands when buying different products. The purpose is to get a clearer idea about the brands' importance in the future and in that way also to give guidance to companies about how to best market themselves and there products.To answer the question, an experiment was conducted with 480 respondents taking a survey where they had to rate a product after reading a short text about it. Some of the texts stated that a specific brand was behind the product while some said the product was produced by an unknown brand.The result of the study was that young people showed a greater propensity of rating products with a brand higher than products without brands, in comparison with the older respondents. This gives reason to believe that brands progressively will become an even more important tool for marketers and an unmatched asset for companies in the future..

At Volvo Construction Equipment outside Eskilstuna a wide range of heavy equipment machines are developed that are used by a variety of industries worldwide. For the handling and maintenance of these machines a deep knowledge is often required. Volvo CE and their dealer Swecon offer courses for both drivers and technicians that last for 1-2 weeks. Out on the workplaces however, the knowledge from these courses need to be supplemented with information from the machine?s operator and repair manuals.

The world today is experiencing an AI summer, urging us to engage with its technologies on a daily basis. Recently, researchers have begun to voice concerns about the potential risks if we do not address the inherent biases in these systems. After all, AI is merely code based on mathematics produced by humans. This essay focuses on Stable Diffusion and Midjourney to examine biases in fashion representation and how fashion is visualized and reproduced concerning race, social class, and culture. A series of prompts were intentionally written in simple terms such as ?rich,? ?poor,? and ?race.? The results revealed troubling biases, as these programs consistently depicted poor individuals as people of color and portrayed wealthy, elegantly dressed individuals as exclusively white..

Earlier research has shown that combining education with entertainment can improve students motivation in school. With this study we aim to learn more about interactive digital learning resources and how they should be designed to entertain and thereby contribute to motivation. We have identified aspects of educational games that also could be considered when developing interactive digital learning resources, to make them more entertaining and motivating. We have chosen to study and evaluate an interactive digital learning resource called ?Grasp the Disaster?, a fictional online adventure created for students in the ages between 13-15.

Climate changing is a growing problem for many countries and communities over the world. The cities has a huge work to deal with in their reforcements of their cities to be resilient ones. This thesis makes an effort to investigate and illuminate some of the problem the cities has to solve related to flooding, hazards, erosions, rising sea levels and crotches. This thesis will help to find solutions that international and national efforts has produced and handed out to each other. A lot of communities are charing their excellent tools that works for them.

certain building or environment can get a protection as a notable building if it contains certainvalues. These values are established by a certain category of people from the cultural sector.These people use established criterions to define the cultural value of the object. The objects canbe evaluated differently depending on who has done the evaluation. The people who protect thecultural environment and choose which buildings that are to be defining as notable buildingsoften uses a special model to characterise the different cultural values. This model is produced bya man called Axel Unnerbäck.

The Swedish Transport Agency has for a long time collected data on a monthly basis for different variables that are used to make predictions, short projections as well as longer projections. They have used SAS for producing statistical models in air transport. The model with the largest value of coefficient of determination is the method that has been used for a long time. The Swedish Transport Agency felt it was time for an evaluation of their models and methods of how projections is estimated, they would also explore the possibilities to use different, completely new models for forecasting air travel. This Bachelor thesis examines how the Holt-Winters method does compare with SARIMA, error terms such as RMSE, MAPE, R2, AIC and BIC  will be compared between the methods. The results which have been produced showing that there may be a risk that the Holt-Winters models adepts a bit too well in a few variables in which Holt-Winters method has been adapted.

This essay is a qualitative content analysis of Flickornas julbok andPojkarnas julbok from 1915/1916 to 1920 and from 1966 to 1970. Mainfocus is the representations of gender that is produced in the books, and howthe ideal of the girl and the ideal of the boy is described.The result shows that the girl is undergoing a change of personality. The idealimage of the girl develops from caring, helpful, compassionate, and diligent,to become independent and brave. The Ideal for the boy in the books, bothfrom the 1910s and 1960s, is described as adventurous, courageous, curious,independent, sensible, strong and loyal. In the 1960s books the girl and theboy are described with similar characteristics, but the girl is also expected tobe cute while boy is expected to be technical and knowledgeable.

The forest in the northern part of Sweden has changed dramatically during the last centuries. The forest has gone through a large-scale transformation, from it being only used locally for domestic purposes to becoming very important raw material for Sweden in the industrial age. The strategy by foresters during the second half of the 20th century has been to create pure production forests for commercial forestry. This has mainly succeeded and we have today homogenous production forests that give a high profit to the owners. The aim of the study is to compare the state of the forest in the former state forest Hällforsmarken in the years 1925 and 2000 and to interpret the changes which has taken place.

Since the demands from authorities regarding lower energy consumption havebecome increasingly strict, this puts new pressure on designers and builders, who notonly have to ensure an esthetically pleasing building, but also make sure it issufficiently efficient to pass under new laws and regulations.This thesis takes into consideration a wide range of various parameters and theireffect on a building?s energy consumption. For this evaluation a computer softwarecomparison between the two programs Autodesk Ecotect Analysis and AutodeskProject Vasari was performed.Autodesk Ecotect Analysis is better suited for studies made on individual factors whileAutodesk Project Vasari is better used in experiments regarding the geometricalshape of the stucture itself.The results from the two different software tools used, give us both differences andsimilarities. For instance, both software programs produced the same resultsregarding the importance of the windows of the buildings to ensure a highly energyefficient building, both when it comes to the windows size and their U-value..

The objective of this project was to develop the visual identityof Halleluja, a brand new booking agency representing approximatelytwenty minor artists within a wide range of contemporarymusic styles.The outcome has been applied to business cards and awebsite yet to be produced. To attract the audience and differentiateitself from other booking companies, Halleluja featuresa minimalist design that speaks of dedication, breadth ofgenres and exclusive taste. Although my sketches have beenapproved by Lars Olsson and Erik Sundfeldt, the co-foundersof Halleluja, I have had the privilege of working quite freely andstarting from scratch, since there was no earlier work done onthe company.Some of the issues I have faced during my process wasabout finding the right tone of voice in type and colour, ordealing with the semantics of the corporate name (meaning»praise the Lord«). I?ve also been struggling to come to termswith my own self-censorship and my slighly suspicious view onbranding..

Between 1965-1974 one million new flats were produced in Sweden and the project is called the millionprogramme. One of the areas that was build during this period of time is Rosengård in Malmoe. Today Rosengård is a very segregated area, not just in relation to the city of Malmoe, but within itself. I´ve chosen to study the ideologies behind one of the actors acting and non acting regarding the segregation complex of problems in Rosengård, the housemanagers. I´ve studied one public housecompany and two houseassociations who all owns and manages houses in Rosengård.The ideologies that I´ve studied in this study is what the informers think of the people that live in Rosengård, the society in general, Rosengård and the diffrent smaller areas within Rosengård.

This report shows methods and workflow when exploring the potential to change Outotecs HCD Silver Electrolysis machine to a module type. It?s done as an attempt to lower the workshop and installation costs and to give customer a more accurate prize directly. To do this a concept was produced which was set to a stress test. Additional objectives were to investigate freight and installation procedures, pneumatic connections and to calculate the difference in cost.Once the concept, a reinforced type of the original frame, was chosen stress tests in computer simulations were made and appropriate alterations were made.
