Busshållplatsers kapacitet : Utvärdering av tillämpbarhet av modell från Highway Capacity Manual 2000 med uinderlag från busstrafik i Stockholms innerstad
Stockholm is growing with almost two fully loaded SL-buses a day. One of the consequences that derive from this is the increase of public transport travelers who put the regionally governed public transport up to the test in terms of its capacity. The Transport administration in Stockholm County initiated 2015 a project with the purpose of simplifying the calculation of bus stop capacities. A hypothesis (set up by the Transport administration) based on that a model for calculation of bus stop capacities could be calibrated for Stockholm conditions is being researched in this bachelor?s essay.The study is implemented by self-collected traffic data from bus stops located in the Stockholm city center.
En jämförelse mellan fyra olika energisystemlösningar : För ett hus byggt efter passivhusstandard i Karlstad
AbstractWork to develop the Eurocodes started in 1975 by the European Commission adopted a program to eliminate trade barriers within the construction area. The goal was to create common European design standards that would replace the member countries' own rules. Eurocodes will replace The National Board of Housing Building and Planning, National Rail, The National Road Administration and other agencies' calculation rules for the buildings structures. The transition to the use of Eurocodes looks like this:Eurocodes set to Swedish standards between 2002 ? 2007They can be used parallel with national standards 2006 - 2009 The total transition is at the end of 2010/2011.Right now is going on a lot of work for replacement of the existing standards to Eurocodes. The transition to the new calculations` standards, many construction companies and consulting firms facing a big changes and competitions.
Att finna den positiva avvikelsen : En fallstudie av en väl fungerande arbetsplats
AbstractDuring recent years the climate in recruiting new personnel has hardened as a result of high levels of employment and increasing competition in labour market. In order to resolve this problem, organisations have to adapt new strategies to attract and meet the demands of potential employees who have the required competence to meet job requirements.The aim of this study has been to examine a well functioning work place in order to elucidate explicit examples of what employees consider positive, and what can be ascertained as positive deviations. Narratives emanating from the unit manager and personnel illustrate their views on the positive influences found in their working place. Another ambition is to increase awareness and understanding about the factors that promote satisfaction in the workplace and positive deviation; and to utilise this knowledge.Traditional research on organisations has frequently focused on problems. The theoretical point of departure of this study is based on Positive Organizational Scholarship, abbreviated as POS.
Klimatanpassning kring Vänern : om ansvar och problem med att minska risken för översvämningar
Generellt går det att hantera klimatförändringar på två sätt. Dels genom att minska utsläppen av växthusgaser och dels genom att anpassa sig till de klimatförändringar som kommer. I denna uppsats kommer jag att fokusera på klimatanpassning. Ett av de områdena i Sverige som beräknas drabbas värst är runt Vänern, framförallt då sannolikheten för översvämningar väntas öka på grund av klimatförändringarna. Syftet är att ta reda på vilka problem det finns med att genom klimatanpassning minska risken vid översvämningar kring Vänern, samt undersöka vem som har ansvaret att lösa dessa problem.
"Två hjärnor tillsammans ger mer kunskap än en!" : En kvalitativ studie utifrån fyra lågstadielärares tankar och erfarenheter gällande den muntliga kommunikationen i klassrummet
This study focuses on oral communication in the classroom involving discussion and dialogue amongst pupils, but also between teacher and pupil. The overall aim is to study the choices regarding the group composition and working methods that might occur in four individual teachers? lessons plans with the intention of increasing the pupils? knowledge through oral communication. The main focus is to explore what the teachers think of the choices they make and how they believe these changes affect the pupils. It is also focused on how the teachers perceive their pupils? learning is improved by oral communication and how they incorporate all pupils, especially the pupils who rarely participate in classroom activity.The methods used are qualitative studies using interviews and observations.
Fiskarebönder och landskapet i Karlshamns skärgård förr och nu
Hällaryd archipelago, consisiting of approx. 50 islands, islets and skerries, is situated east of Karlshamn city in Blekinge province. The archipelago has been shaped into a rift valley by volcanic activity, the inland ice and maritime climate.The archipelago is divided into seven main islands: Bockö, Västra Bokö, Ekö, Hallö, Joggesö, Mjöö and Tärnö. This essay will connect population changes with land use.
Tilla?mpning och simulering av naturlig ventilation : Potential fo?r utnyttjande i kontorsrum
Mechanical ventilation is the most common type ofventilation in newly constructed office buildings. Therehas been an interest to utilize natural ventilationinstead of mechanical ventilation among architects andHVAC consultants in recent years. This is due to thesize of mechanical ventilation systems, which arespace consuming. The mechanical ventilation system isalso complex and requires maintenance. Furthermore,the fan uses a considerable amount of energy.
DYNAMIKEN OCH EFFEKTEN AV MARINA V?RMEB?LJOR P? TROPISKA KORALLER (SCLERACTINIA)
Marine heatwaves (MHW) have become increasingly common in recent decades due to greenhouse gas emissions that have caused climate change. A marine heatwave is when the sea surface temperature rises, which damage many different ecosystems in the sea. One ecosystem that is sensitive to temperature changes is tropical coral reefs, which are at risk of bleaching during marine heatwaves. Coral bleaching is when its symbionts leave the coral and they lose their color, while also starving to death as they lose their food source. The purpose of this report was therefore to investigate what the connection between marine heatwaves and coral bleaching looks like, and to see if there are any geographical differences.
Göteborgs pendlingsomland. En studie om hur restid och reseavstånd korrelerar med pendling och befolkninsförändring i Västra Götalands och Hallands Län
The daily travel, and especially travel between home and work i.e. commuting, is increasing every passing year. More than 90 000 people commute from their home municipality to work in Gothenburg. One of the aims of the regions of Västra Götaland and Halland is to interconnect municipalities and towns within the region, thereby creating growth, faster freight and passenger transports as well as a more attractive business climate. However, while the goal is to create growth, there are several municipalities in the study region with negative ongoing trends.
Odling av vedartade växter i kärvt klimat : En studie om zonkartans användning i Norr- och Västerbottens län
Härdighet för vedartade växter förknippas oftast med zonkartans zonangivelser. Det är dock inte enbart härdighetsiffran som bestämmer om en växt är härdig eller inte. Klimatet på platsen är en avgörande faktor för hur en växt klarar sig eller inte. Via en enkät tog jag reda på vad odlare i Norr- och Västerbottens län tycker om zonkartan och hur de använder sig av den när de väljer vedartat växtmaterial. Nästan alla odlare ställer sig positiva till zonkartans zonangivelser. De påpekade dock brister med användandet av den då den inte tar hänsyn till växtens proveniens, lokalt klimat eller växters krav på odlingsplats vilket är viktiga faktorer som påverkar härdigheten hos växten.
SAMMANS?TTNING AV MAKROALGER I SVENSKA ?LGR?S?NGAR eDNA sp?rning och klimatf?r?ndringar
The aim of my bachelor?s thesis is to investigate, through a literature review, changes in the
distribution of filamentous algae as well as the general species composition of macroalgae
and diatoms in Swedish eelgrass meadows. I have also studied the possibility of tracking
these algae and diatoms in eelgrass meadows using eDNA methodology. The focus has been
on linking these changes to climate change factors such as eutrophication, temperature
increase, and anthropogenic emissions, and how these affect the health of eelgrass meadows
and their ecosystem services, such as a carbon sink and biodiversity support.
The results show that filamentous algae have increased markedly in coverage in Swedish
coastal areas between 1980 and 2021, especially in sheltered bays, indicating that altered
environmental conditions favor these fast-growing species. Genetic tracking using eDNA
demonstrated that there are functional primers for many species, particularly among brown
algae and red algae, whereas green algae require more specific primers due to greater genetic
variation.
Lufttäta byggnader
The viscosity of air buildings is a hot topic within the construction performers, which the industry feel they have too little knowledge about. This study is mainly aimed against air density in apartment buildings and airflow measurement. The study consists of a theoretical reference, educational visit, interviews and a survey conducted among construction workers at Magistratshagen in Linkoping.Earlier requirement in terms of air leakage through the climate screen was removed and today there are only energy requirement for a dwelling in Boverkets Building Regulations. The difference between a passive and a typical air tight construction is that the passive house have a maximum requirement of 0.3 l /s m2 of air leakage through the building climate screen. The requirement imposed on passive houses is to minimize the supply of power and energy for heating the building.Air tight constructions have heavy demands on the performance and accuracy of everyone involved with the project. The client must specify their requirements and also be prepared to pay for any additional costs. The architect and building planners have to design the building with regard to air tightness. Finally, the construction workers are required to do a careful work in order to get all the connections in the building air tight.The study suggests that an air tight building is a closed system where no forced ventilation exists. There are no reasons not to build too tight as long as there is a functioning ventilation. In this study the authors ask themselves how an air tight building changes over time. No theoretical information has been found on these changes, but the respondents assume that air density decreases with time. The deterioration is mainly assumed to be caused by construction materials changes over time. The study shows that construction workers knowledge of air tight construction is mixed, which they themselves admit in the survey..
Högtrycket-Initierande undersökning av nytt limträmaterial
The present study examines a new production line of glue-laminated wood (glulam). The glulam is produced from non-planed boards of spruce, which also is convex, that is pressed together with high pressure during the gluing. According to a economic calculation, the material has a economical potential mainly on account of the absent planning. The study mainly found out that the shear strength of the material tolerated the demanded values in standard SS-EN 386, but the delaminating values did not. Since there are more areas to be studied around the material, the prospect to achieve the right delamination values is seen as positive..
DELMIA V6 Machining
Staden Sulaymaniyah ligger i den kurdiska delen av Irak och har på senare år utvecklats då många valt att flytta från landsbygden till den centrala delen av staden. Nybyggandet sker under tidspress och långsiktigt hållbara lösningar prioriteras inte. Målet är att ta fram ett hus som är anpassat för majoriteten av befolkningen och samtidigt få ett bra och energieffektivt inomhusklimat. En faktainsamling genomfördes för att ge bakgrundsinformation till projektet. Vidare gjordes en planlösning till huset i AutoCAD vilken har använts som grund till utformningen av huset och smarta lösningar.
Solenergi på Kvarnholmen
In recent years it has become more and more evident that man has contributed to much of the climate changes that have taken place during the last century. A major challenge today is to reduce emissions and energy usage at the same time as the global population is growing. To contribute to a better environment, Stockholms Stad has set at target of becoming fossil fuel free by the year of 2050. The construction of new districts is done with this goal in mind; energy efficiency and renewable energy sources are examples of methods to achieve this.Solar energy is considered to be a sustainable energy source and the most common techniques to harvest solar energy in Sweden are solar cells and solar collectors which produce electricity and heat respectively. This report aims to investigate whether an investment in any of these systems would prove to be economically beneficial at Kvarnholmen, a district under construction in eastern Nacka, Stockholm.Since the finished blueprints only cover a small portion of Kvarnholmen, the report examines the possibilities for a house where construction has already begun, Nya Kvarnen.
