• Leveling Up In Design
  Larsson, Emma  : Malmö universitet/Teknik och samhälle (2019)	Master thesis (one year)

  

  

  English abstract:

  Design is a very ambiguous term. It can be referred to as a thing, an activity, a process, and even a strategy. Because of its many meanings and definitions, it is argued that design can have more than one purpose or role. It is also argued that these roles can mature and expand within the organizational frames, which in turn can have an effect on the organizational culture and business strategy. Recent studies have shown that design-led organizations outperform other organizations in terms of stock market value and competitive advantage. As such, the topic of using design strategically, in combination with the question of how to mature in design, has become popular, both in the academic world and in the business world. In response, different models have emerged claiming to assess organizations in relation to how they utilize design. These models can evoke discussions that subsequently can lead to knowledge exchange and potentially drive actions toward change. This thesis explores how organizations go about maturing in design, as well as the challenges and benefits they see within this process. Furthermore, it examines the use of a game as a boundary object to facilitate knowledge exchange and support organizations in their efforts of maturing in design. Findings include that when utilized in a workshop setting, the game facilitated discussions, knowledge exchange and knowledge appropriation related to design in the organization. Through these findings, it is argued that the boundary object has the potential to support the organizations in their efforts of maturing in design.

• Pupils' Feedback
  Kapolka, Felix  : Malmö universitet/Teknik och samhälle (2019)	Master thesis (one year)

  

  

  English abstract:

  In a contemporary world saturated with technology, where data has become a means to understand and optimize almost everything, the educational sector seems reluctant towards it. In order to change that, it is argued that formative assessment is a sustainable way to monitor feedback data for the purpose to improve school environment. Used in the classroom, it shifts the focus from the outcome of pupils’ learning to their real needs. This study elaborates on the lack of feedback for teachers and the referring potential of technology usage in schools. Due to, inter alia, a co-creation workshop, novice teachers and designers collaborated to create several prototypes, which were used in a real classroom situation afterwards. Those prototypes enabled a deep understanding of the current perception of feedback as well as the technology awareness of students and teachers. The research results were discussed from various angles, including young teenagers’ and experienced teachers’ views. The outcome analysis led to the need of a student-centred curriculum which offers explorative access to technology and feedback for everybody involved in a school environment.

• Intersection coordination for Autonomous Vehicles
  Alhuttaitawi, Saif  : Malmö universitet/Teknik och samhälle (2019)	Master thesis (one year)

  

  

  English abstract:

  Connected Autonomous Vehicles require intelligent autonomous intersection management for safe and efficient operation. Given the uncertainty in vehicle trajectory, intersection management techniques must consider a safety buffer among the vehicles, which must also account for the network and computational delay, queue and determine the best solution to avoid traffic congestions (smart intersection management), in this paper we model traffic by using Poisson distribution method then add a birth-death processes for each state and combine both two in one queuing system (The Markovian chain) to model the traffic. Also, this paper will compare some autonomous vehicles communication techniques in intersections to draw the best scenario for autonomous vehicle network communication in order to reduce the traffic congestion in an intersection. The Connected Autonomous Vehicles and a normal autonomous vehicle, as well from the third line of the intersection a mix between the both will be provided into the intersection. The last section is about applying the results from the first and second research question into a simulator and compare the simulation results to approve the advantage of using the next generation of transportation technology (The connected autonomous vehicles) over the normal conventional vehicles.

• Development of cutting machine for printed circuit board
  Salih, Renoar; Krikor, Shant  : Malmö universitet/Teknik och samhälle (2019)	Bachelor thesis

  

  

  English abstract:	This project has been carried out in collaboration with Inission AB in Malmo. Inission AB produces printed circuit boards, hereby referred as PCB. The PCBs are inserted in to a machine that automatically solders all components on to the PCBs. The solder cards are two PCBs together that need to be separated. These cards have 51 mm high capacitors. The cutting machines available can’t cut PCB with components of that height which leads to manual soldering of the high components after the cutting of the PCB. Inission AB in Malmo calculates a loss of 4 hours per week due to the manual soldering. To enable cutting of the PCB with the high components and eliminate the 4 hour time loss, a new cutting machine has been developed. It has resulted in CAD-models, drawings and the materials of the components have been selected, which have been the goals of this project. This cutting machine is made from six larger parts. It uses a linear motion rail guide to bring a circular cutting along a cutting plate with a speed of 500 mm/s. The cutting plate is 5 mm thick and high enough to be able to cut circuit boards with components up to 61 mm high, which enables cutting of the PCBs with the capacitators already soldered on to the cards. Solid mechanics calculations have been done to calculate the deformations of the machine. Materials have been selected on all the parts of the construction. The stand will be created in cast iron and the circular blade and cutting board will be made in titanium. Production of the cutting machine will be done in conjunction with Inission AB.
  Swedish abstract:	Detta projekt har utförts i samarbete med Inission AB i Malmö. Genom att föra mönsterkort i en maskin lödas alla komponenter på dessa kort med maskinen. Korten är två kort som sitter ihop som sedan ska delas. Dessa kretskort, som de blir efter komponenter har fästs på mönsterkorten, har 51 mm höga kondensatorer. Skärmaskiner som finns tillgängliga klarar inte av att skära i dessa kretskort vilket leder till en manuell lödning efter skärningen. Inission AB i Malmö beräkna förlora cirka 4 timmars arbetstid per vecka på grund av denna eftermontering. För att kretskorten ska kunna skäras med alla komponenter fästa och på så sätt eliminera eftermonteringen, har en ny skärmaskin utvecklats och har resulterat i CAD-modeller på maskinen, ritningar och material har valts, vilket har varit målen med detta arbete. Denna skärmaskin består av sex större delar. Den använder skenstyrning för att driva ett cirkulärt skär över en skärplatta där kretskortet ligger med en hastighet på 500 mm/s. Detta delar på kretskortet och då skärplattan på konstruktionen är 5 mm tjock och tillräckligt hög kan kretskort med komponenter upp till 61 mm skäras, vilket leder till att Inission ABs kretskort med 51 mm höga kondensatorer kan skäras med denna maskin. Hållfasthetsberäkningar har gjorts för att beräkna utböjningar på maskinen. Material på alla delar har valts till konstruktionen. Stativet kommer att tillverkas i gjutjärn och skären kommer att tillverkas i titan. Tillverkning av skärmaskinen kommer att göras i samarbete med uppdragsgivare Inission AB.

• Inverkan av omgivande klimatets temperaturförändringar på mätresultat...
  Viktor, Olsson  : Malmö universitet/Teknik och samhälle (2019)	Bachelor thesis

  

  

  English abstract:	In this bachelor thesis a study is done to see how ambient climate changes impacts the measurement results during moisture measurements in concrete. The method of measurement used is borehole measurements according to the RBK-system, Manual – Fuktmätning i betong. The experiments were conducted in a laboratory environment on a concrete slab, which was casted with bascement and had a w/c ratio of 0,38. To see how well the moisture meter performed during ambient climate changes eight thermistors were cast into the concrete slab to log the temperature at different depths of the concrete during the ambient climate changes. The results show that the moisture meter does read the actual temperature of the concrete during an ambient climate change, however the ambient climate change had an impact on the measurement results of the relative humidity (RH). If a snapshot measurement of the RH is done after a temperature change in the ambient climate, an incorrect measurement result of the RH is obtained. When the obtained RH is converted to RH at 20°C the fault will get enlarged. To obtain a correct RH measurement when a field measurement is done, a logged measurement should be conducted.
  Swedish abstract:	I detta examensarbete som utfördes under vårterminen 2019 på Malmö universitet undersöktes hur temperaturförändringar i det omgivande klimatet påverkar mätresultat vid fuktmätningar i betong. Vid fuktmätningar i betong, i fält, används metoden borrhålsmätning. Vid borrhålsmätningar borras ett hål i en betongplatta eller ett betongbjälklag, därefter monteras ett mätrör i hålet sedan monteras en fuktgivare. Detta görs vanligtvis enligt RBK-systemets, Manual – Fuktmätning i betong. För att undersöka hur temperaturförändringar i det omgivande klimatet påverkar mätresultatet vid fuktmätningar utfördes försök där en provkropp gjöts med bascement, vct 0,38. Åtta termistorer gjöts in på olika djup för att kunna logga temperaturen på olika djup i provkroppen vid en temperaturförändring i det omgivande klimatet, dessa mätvärden jämfördes sedan med den loggade temperaturen samt de loggade RF-värdena från fuktgivaren. Fuktgivaren som användes vid försöken var Vaisala HMP110. För att utföra kontrollerade temperaturförändringar utfördes försöken i en fuktgenerator. Tre huvudförsök utfördes, ett med en momentan temperaturförändring i det omgivande klimatet, ett med en långsam temperaturförändring i det omgivande klimatet samt ett där okontrollerade temperaturförändringar i det omgivande klimatet skedde. Resultaten från dessa försök visar att när en temperaturförändring i det omgivande klimatet sker mäter fuktgivarens temperatursensor betongens faktiska temperatur med god noggrannhet, men ett felaktigt RF-värde kommer att ges om en avläsning av mätvärdet sker innan en ny temperaturjämvikt har etablerats. Resultaten visar även att vid omräkning av RF till RF vid 20°C, enligt RBK-systemet, förvärras mätfelet när temperaturen inte är stabil i det omgivande klimatet.
