Detta examensarbete går ut på att konstruera en upphängningsanordning för en provrigg på Scania. Scania har i dagsläget ett flertal olika provriggar, en provrigg de har är T22. Syftet med detta arbete är att utveckla en fixtur som har egenskapen att stödja en tung växellåda så den utgående axeln på växellådan kan provas i provriggen T22. Metoden som används för denna utveckling består av flera moment där den första delen är att mäta nuvarande mått på växellådan och modellera en fixtur med hjälp av de mått som tagits i CAD-programmet CATIA. Därefter kan fixturen som konstruerats i CATIA sammanställas ihop med växellådan för att se om dimensionerna stämmer. När sammanställningen har genomförts kan mekaniska analyser utföras och sedan avslutas med tester. Resultatet av projektet blev en upphängningsanordning som monteras på Scanias växellådor som i sin tur kopplas ihop med provrigg T22. Scanias befintliga komponenter som lyftbalk och cirkulär konsol användes och kompletterades med armar som möjliggör att montera växellådan bakifrån i provrigg T22. Av det här resultatet kan vi dra slutsatsen att Scania kan montera fixturen på de allra flesta GW växellådorna och utföra mätningar via provriggen T22. / This thesis is about designing a suspension device for a test rig at Scania. Scania currently has several different test rigs, one test rig they have is T22. The purpose of this work is to develop a fixture that has the property of supporting a large gearbox so that the output shaft of the gearbox can be tested in the test rig T22. The method used for this development consists of several parts where the first part is to measure the current dimensions of the gearbox and then create a fixture in the CAD program CATIA V5 adapted to the dimensions taken before on the gearbox. Then the fixture constructed in CATIA V5 can be assembled with the gearbox to check if the dimensions are correct and fits together. Once the compilation has been completed, mechanical analyzes can be performed and then conclude with tests.The result of the project was a suspension device that is mounted on Scania's gearboxes which in turn are connected to test rig T22. Scania's existing components such as lifting beam and circular adapter were used and supplemented with arms that allow the gearbox to be mounted from behind in test rig T22.From this result we can conclude that Scania can mount the fixture on most GW gearboxes and perform measurements using the test rig T22.

This research paper is discussing light, and brightness in particular, in terms of perception, taking Odenplan as a case study.Some links between light characteristics and behaviour patterns, such as lingering, have been made, raising the discussion about the qualities of the artificial lighting that would add to convivial urban spaces at nighttime, attempting at differentiating between how people think they would behave and how they actually behave in a public square, and the impact of artificial lighting on public tendencies, suggesting if people feel comfortable and safe in the space, then they tend to perceive the space brighter. The research has shown that it is hard to draw conclusions when it comes to perceived qualities of light. Different research methods have been used with the intention of suggesting a methodology to be explored by others, including literature review, empirical study, informal interviews and word association survey.

Bakgrund: Som resultat av globaliseringen och den ökade miljömedvetenheten har det medfört att logistikens roll blivit allt viktigare. För att företag ska förbli konkurrenskraftiga måste de koncentrera sig på att vara kostnadseffektiva samtidigt som de upprätthåller en hög nivå av kundservice. För att beslutsfattare ska kunna fatta bra beslut är en totalkostnadsanalys (TCA) ett viktigt verktyg för att stödja deras arbete. En TCA tar dock inte hänsyn till hur logistikkostnader kan utvecklas i framtiden vilket kan leda till en missvisande analys som kan få negativa konsekvenserför ett SME företag. Eftersom framtiden är svår att förutsäga kan en scenarioplanering vara ett verktyg för beslutsfattare eftersom denna metod tar hänsyn till externa faktorer och skiljer sig därmed från traditionella prognoser. Syfte: Syftet med denna studie är att upprätta en totalkostnadsanalys för respektive alternativ med fokus på logistikkostnader till Timber Windows som sedan ska kunna användas som underlag för beslutsfattande vid placering av hubb. Studiens syftar också till att skapa förståelse och undersöka hur en scenarioplanering kan addera mervärde till en totalkostnadsanalys med fokus på logistikkostnader för att utvärdera placering av hubb. Metod: För att kunna svara på studiens första två forskningsfrågor har en kvantitativfallstudie genomförts tillsammans med en deduktiv ansats. Till studiens tredje och sista forskningsfråga har istället en induktiv ansats använts. Primärdata har samlats in genom semistrukturerade intervjuer och därefter kompletterats med sekundärdata från fallföretaget Timer Windows, vetenskapliga artiklar, litteratur samt inhämtning av data från olika webbplatser. Slutsats: Studiens resultat visar att de identifierade logistikkostnader för Timber Windows nuvarande hubb i Vimmerby samt vid en eventuell flytt till Jönköping eller Stockholm är lastbil, drivmedel, personal, lager och truckkostnader. Studiens sammantagna totalkostnadsanalys visar att en flytt från Vimmerby inte skulle minskaTimber Windows logistikkostnader. Detta resultat kan ifrågasättas efter att scenarioplaneringen med scenariot High score genomförts som visar att Jönköping om tio år skulle kunna vara det bättre alternativet, jämfört med Vimmerby, eftersom det skulle bidra till kortare transportsträckor och därmed göra det möjligt för Timber Windows att utnyttja sina styrkor. Sammanfattningsvis kan studien konstatera att en scenarioplanering kan ge ett mervärde till en totalkostnadsanalys med fokus på logistikkostnader genom att beakta hur olika trender och drivkrafter kan komma att påverka framtiden. Vilket ger beslutsfattare i Timber Windows en mer omfattande och realistisk bild av potentiella framtida händelser som kan påverka logistikkostnaderna för valet av hubb. / Background: The result of globalization and increased environmental awareness has made the role of logistics increased significantly. Furthermore, this has also meant that companies must concentrate on being cost-effective while maintaining a high level ofcustomer service to remain competitive. For decision-makers to make good decisions,a total cost analysis (TCA) could be an important tool in order to support them. However, a TCA does not take into consideration how the logistical cost may changei n the future. By only including current costs without taking into account that these may change can lead to a misleading analysis which could have negative consequences for a SME. Because the future is difficult to predict, scenario planningcan be a great tool to the decision-makers as the method takes into account external factors and thus differs from traditional forcastings. Purpose: The purpose of this study is to establish a total cost analysis for each option(Vimmerby, Jönköping or Stockholm) with a focus on logistics costs for TimberWindows, which can then be used as a basis for decision-making on the location of thehub. The study also aims to understand and explore how scenario planning can add value to a total cost analysis focusing on logistics costs to evaluate the location of the hub. Method: To answer the study's two research questions, a quantitative case study with a deductive approach has been conducted. To answer the study's third and final research question, an inductive approach has been used instead. Furthermore, primarydata has been collected through semi-structured interviews and then complemented with secondary data from Timber Windows, scientific articles, literature and different websites. Conclusion: The results of the study show that the logistics costs identified in Timber Windows current hub and in a location in Jönköping or Stockholm are truck costs, fuel costs, storage costs, personnel costs and vehicle costs. The study's total cost analysis shows that a move from Vimmerby would not reduce the logistics costs for Timber Windows, a result that can be questioned after the created scenario High score, which shows that in 10 years, Jönköping may be the better choice, instead of Vimmerby, as it contributes to shorter transport distances and enables Timber Windows to utilize its strengths. In conclusion, the study shows that scenario planning can add value to a total cost analysis focusing on logistics costs by addressing how different trends and drivers may affect the future, giving Timber Windows decision-makers a more comprehensive and realistic picture of potential future events and potential situations that may affect the logistics costs of the hub selection.

Truck platooning is a technology where trucks drive in a formation with each other with a small distance in between trucks in order to save fuel and reduce emissions. In this project,a distributed method for solving the optimal time problem for every truck in a hub-based transport system will be developed.Each truck will have its own utility function to optimize and is able to adjust its schedule independently. To create and test the method, a simulation of hundreds of trucks in a network of routes was created using the Python language. The results produced by running the simulation were positive and realistic. / Konvojkörning med lastbilar är en teknologi där lastbilar kör i en formation med varandra med små avstånd mellan lastbil för att spara på bränsle och minska utsläppen. I det här projektet kommer en distribuerande metod för att lösa det optimala tidsschemat för varje lastbil i ett navbaserat tranportsystem att utvecklas. Varje lastbil kommer att ha sin egen vinstfunktion att optimera och kommer självständigt att kunna ändra sitt reseschema. För att skapa och testa metoden kördes en simulation som skrevs i Python, och som behandlade hundratals lastbilar i ett nätverk av vägar. Resultaten som simulationen cerade var positiva och realistiska. / Kandidatexjobb i elektroteknik 2022, KTH, Stockholm

With funding from the National Science Foundation (NSF), the Ira A. Fulton College of Engineering and Technology at BYU has been furthering their research on Global Virtual Teams. After Cultural Competence lessons were implemented into the classroom setting in 2010, it was decided that teaching the lessons online asynchronously could have advantages in decreasing the time professors needed to cover the content in class. In 2011, Jennifer Alexander teamed with faculty involved with the NSF grant to design and develop online Cultural Competence lessons. Beginning in August 2011 students at BYU and other cooperating campuses participated in the online Cultural Competence lessons. The online lessons were complete and ready for implementation on time; changes were made after implementation based on feedback given in student interviews; and the lessons are now ready for further development and implementation. The lessons will be shared openly with a global audience through Global Hub beginning in summer 2012.

Walking speeds are an important parameter in the process of designing for example arenas, malls and station environments, to be able to make them safe and comfortable for the users. Previous studies have mainly focused on pedestrian walking speeds at zebra crossings and the results of these are the basis for traffic signal timing. The studies have also investigated the relationship between walking speed and gender, age and density of pedestrians. From the results of these studies, conclusions have been drawn that these three factors have an impact on pedestrian walking speeds. To make microsimulations of pedestrians reflect reality as well as possible, pedestrian walking speeds should be investigated at regular intervals, as walking speeds change with the ongoing change of the composition of the population. In the simulation of station environments, pedestrian speeds should also be used that have been measured in these types of environments. Alternatively, the speeds should be measured at locations near stations, rather than using speeds from zebra crossings. As a step in improving the above-mentioned microsimulations, the aim of this work is to study walking speeds at a public transport hub during rush hour. The work also focuses on connecting walking speeds to each sex and level of crowding. To achieve this goal, video recordings were performed at the exchange point between Stockholms östra and Tekniska högskolan in Stockholm, Sweden, where public transport passengers change between light rail and subway. Analysis of the video films resulted in walking speeds which were higher than those previously measured at zebra crossings. The most obvious factors explaining this are the differences in the environment where the studies were conducted and that the walking speeds in this thesis were measured during rush hour. The results show that simulations of stations and locations nearby should not be based on walking speeds measured at zebra crossings. Analysis of the video films also resulted in the calculated mean walking speed of women being marginally lower than for men. Regarding the link between density of pedestrians and their walking speeds a conclusion can be drawn that at low densities pedestrians have good opportunities to freely select their own walking speed. The freely chosen walking speed which can thus be maintained at low densities can vary widely between different individuals. At higher, unlike at lower densities, it is difficult for pedestrians to maintain a freely chosen speed due to interactions with other pedestrians. The calculated average walking speed at higher densities therefor decreases as the density increases. Interactions with other pedestrians can either mean that a pedestrian is forced to lower the speed or that he or she must walk faster to keep up with the current pace. When analyzing the video films, several other factors effecting the walking speed could be noted. Of these factors, grouping of pedestrians and if the pedestrian is using a phone or carrying luggage could be seen to decrease the pedestrian speed. These factors’ impact on walking speeds was only superficially studied in this thesis, and no reliable conclusions can therefore be drawn. Keywords: Pedestrian walking speed, public transport traffic hub, density of pedestrians, Level of

Shared mobility is considered a more sustainable alternative to private modes. Nonetheless, its sudden and sometimes “out of control” emergence poses issues that need to be addressed. Lack of regulations and public space mismanagement cause sidewalks and city roads to be overcrowded with shared vehicles (especially in the case of micromobility). This causes nuisance and safety concerns and hinders the societal benefits shared mobility may provide. Shared mobility hubs have the potential to address these issues. The research was carried out within the context of the SmartHubs project, an EIT Urban Mobility project initiated in 2021 by a diverse consortium of 7 cities, companies, and universities to develop and validate effective and economically viable mobility hub solutions. This degree project aims to improve the Decision-Support-Tool (DST) developed by SmartHubs to identify locations of shared-mobility hubs having high potential in driving sustainable travel usage. To achieve that, the thesis proposes a methodology for determining smart hub locations and their corresponding utilities based on the combination of GIS cluster analysis of free-floating shared mobility parking patterns and a stated-preference study. The potential hub locations were determined from the cluster analysis of free-floating trip characteristics. Using the stated preference survey data, the thesis develops a model to estimate the probability of parking at the hub as a function of explanatory variables, including walking distance, reward policies and the parking situation. The model testing results showed that the proposed methodology can well predict the hub (usage) demand and improve the current DST originally developed in the SmartHubs project.

I samhället pågår en trendförflyttning som innebär; ett ökat antal elektrifierade och energieffektivare fordon, ökad förnybar energi och utvecklingen av ett transporteffektivt samhälle. Anledningen till trendförflyttningens aktualitet är en kombination av att urbaniseringen fortsatt ökar och att transportsektorns utsläppsnivåer måste minska för att nå klimatmålen till år 2030. Varje stad är beroende av mobilitet och idag har utvecklingen av mobilitet sammankopplats med våra byggda miljöer och har blivit en viktig del av vår tids fastighetsutveckling. Ett begrepp som implementerats för att främja mobilitet i ett transporteffektivt samhälle är mobilitetshubb. Byggnaden syftar till att främja samnyttjande och delningsekonomi, bidra till en bättre hälsa och tillgängliggöra hållbar mobilitet för alla. En fastighetsutvecklare har en väsentlig men tvetydig roll i realiseringen av en mobilitetshubb idag. Syftet med studien är därför att undersöka hur en fastighetsutvecklare som nyttjar en mobilitetshubbs affärsvärde kan påverkas genom att bidra till realiseringen. Affärsvärdet undersöks utifrån; aktualitet, attraktivitet och ekonomiskt värde. Vidare är avsikten att identifiera en fastighetsutvecklares incitament och investeringskostnaderna vid realiseringen av en mobilitetshubb. En fallstudie på det pågående stadsutvecklingsprojektet Forsåker har genomförts där det planeras för två mobilitetshubbar. Fallstudien baseras på intervjuer med både experter inom mobilitet och fastighetsutvecklare, samt en investeringskalkyl som jämför kostnaderna för att bygga ett garage på egen fastighet och en mobilitetshubb. För en fastighetsutvecklare innebär aktualitet att vara relevant på marknaden och att framtida projekt utvecklas med hänsyn till kundens och samhällets framtida krav och behov. Det leder till att de initialt svarar med nyfikenhet och intresse för den pågående trendförflyttningen och ser främst fem incitament med realiseringen av en mobilitetshubb: (1) Minska byggkostnader vid byggnation av färre parkeringsplatser, (2) uppfylla kundens behov och efterfrågan, (3) öka nyttjandet av byggrätten samt att en trevligare stads- och gatumiljö främjas, (4) öka sin hållbarhetsprofil och (5) bidra till samhällsutvecklingen. Däremot känner fastighetsutvecklarna en osäkerhet kring rollfördelning, affärsmodell och den nödvändiga beteendeförändringen då faktorerna påverkar fastighetsutvecklarens ekonomiska resultat vid realiseringen av en mobilitetshubb. Investeringskalkylen visar att genom att investera i en mobilitetshubb jämfört med att bygga eget garage på sin fastighet, görs en kostnadsbesparing på 14% per kvm BTA. Studien klargör att en investering i realiseringen av en mobilitetshubb är både aktuell, attraktiv och skapar ekonomiskt värde. Därav kommer en fastighetsutvecklares affärsvärde påverkas positivt av att nyttja en mobilitetshubb istället för att bygga eget garage i ett stadsutvecklingsområde. / Currently a trend shift is taking place in society and consists of; an increased amount of electrified and energy-efficient vehicles, increased usage of renewable energy and the development of a transport-efficient society. The reason behind the topicality of the trend shift is a combination of urbanization and that the transport sector's emissions have to decrease if the climate goals set for 2030 are to be reached. Mobility is an important segment of every city. The development of mobility is today linked to the built environments and is an important part of our times property development. A concept that has been implemented to support mobility in a transport efficient society is the mobility hub. The building aims to encourage sharing and sharing economy, contribute to better health and make sustainable mobility available for everybody. A property developer has today an essential but ambiguous role. Therefore, the study aims to examine how a property developer's business value is affected by contributing to the realization of a mobility hub. The business value has been examined based on three factors; topicality, attractiveness and economic value. Further, the intention is to identify property developer’s incentives and what investment costs a realization of a mobility hub brings. The study is based on a case study of the ongoing urban development project Forsåker where two mobility hubs are planned to be developed. The case study is based on interviews with both experts within mobility and property developers, and an investment calculation that compares the costs for a property developer to build a garage on their own property and their costs to use a mobility hub. For a property developer, timeliness means to be relevant and ensure that future projects are developed with consideration to both the customer’s and the society’s future requirements and needs. This results in an initial curiosity and interest for the ongoing trend shift, and the property developers see five main incentives with the realization of a mobility hub: (1) Reduce construction costs because of fewer parking spaces that has to be constructed, (2) meet the customer’s needs and demand, (3) increase the utilization of the building, (4) increase their sustainability profile and (5) contribute to the development of the society. However, uncertainties regarding the distribution of the roles, business models and the behavior change has been recognized. This depends on the fact that these factors affect the property developers economic result in a realization of a mobility hub. The investment calculation shows that a property developer makes a cost saving of 14% per sqm gross area by investing in a mobility hub instead of building a garage on their own property.
