Understanding Organizational Learning in Technology Development and Implementation A case study of how organizational learning could be strength- ened in one of Sweden’s largest manufacturing companies
(2026) Ekvall, Hanna; Salihovic, Medina
Organizational learning has in past research shown to play a critical factor for com- panies seeking to maintain competitiveness. While research has developed different models and frameworks to support learning processes, organizations still face chal- lenges in capturing, sharing and utilizing knowledge effectively. At the same time, emerging technologies are reshaping industrial contexts which put an increasing fo- cus on the importance of how technology development and implementation processes can facilitate organizational learning and competitive advantage. This study, which was conducted at one of Sweden’s largest manufacturing companies explores how organizational learning in the context of manufacturing technology development and implementation can be better understood and strengthened. The study is based on a qualitative approach that combines unstructured and semi- structured interviews, internal document analysis and observations and insights from the daily organizational environment. The material was analyzed through the lenses of the SECI model, the 4I framework, single-loop and double-loop learning and theories on exploration and exploitation. The findings from the case company showed that even while learning takes place locally and within networks, mechanisms for knowledge sharing and coordinations of learnings are limited for reaching cross-functional organizational learning. This leads to duplicated learning and knowledge not being captured in usable formats. Identified barriers from the study were lack of time, unclear roles, limited awareness of who to involve and initiatives remaining within isolated organizational levels. The study contributes to research on organizational learning by highlighting the gap between formal learning structures and actual practices in complex industrial organizations. It further suggests that strengthening organizational learning requires improved integration, visibility and coordination of existing structures and learning activities.
Skalmodell av elvägssystem
(2026) Carlsson, Emil; Eliasson, Leo; Fawal, Omar; Lindvall, Ebba; Ljungqvist, August; Rydberg, Daniel
Elektrifieringen av transportsektorn ökar kraven på kraftdistribution och laddinfrastruktur. Ett sätt att möjliggöra längre räckvidd för elfordon är dynamisk laddning via elektrifierade vägar. I detta projekt utvecklas en fysisk skalmodell av ett elvägssystem för att studera laddning under färd. Projektet omfattar design och konstruktion av fordonsmodeller, modifiering och elektrifiering av en bilbana samt implementering av ett modulärt energilager baserat på superkondensatorer. Utöver detta implementerades ett hastighetsregleringssystem, sensorer och realtidsvisualisering av data för att möjliggöra kontinuerlig övervakning och analys av systemets beteende. Den fysiska modellen kompletteras med en simuleringsmodell som används för att analysera och förutsäga systemets beteende under olika konstruktionsval och driftfall. Experimentella mätdata från den fysiska modellen används för att validera simuleringen. Resultaten visar att det utvecklade systemet framgångsrikt möjliggör laddning under färd och skapar förutsättningar för systematiska studier av hur hastighet, laddningssträcka och energilagringskapacitet påverkar fordonets drift. En ökning av superkondensatorns kapacitans resulterade i betydligt längre körsträckor, samtidigt som laddning i kurvor visade sig ge lägre hastigheter på laddsträckan, vilket i sin tur gav mer laddning per längdenhet. Simuleringsmodellen kunde återskapa det övergripande beteendet hos det fysiska systemet och visade sig vara ett användbart verktyg för kvalitativ analys av systemets dynamik.
Balancing a Stationary Bicycle With a Reaction Wheel
(2026) Oubaid, Adel; Obed, Esmail; Rodung, Isak; Lindgren, Johanna; Bloom, Lukas
This thesis presents the design, modeling, and experimental validation of a stabilization system for a stationary bicycle using a reaction wheel actuator. The bicycle is modeled as an inverted pendulum, and a state-space representation is derived by combining mechanical roll dynamics with the electrical dynamics of a DC motor. The model serves as the foundation for controller design and simulation. Control strategies are developed and evaluated in MATLAB, where system behavior is analyzed under varying initial conditions, disturbances, and time delays. The cascade controlled architecture was proven as the most optimal. Furthermore, the pole placement method is applied to obtain desired closed-loop dynamics, and the influence of key parameters on system stability is investigated. The control algorithm is implemented on an embedded platform and tested on a physical prototype. Sensor data from an inertial measurement unit is processed using a complementary filter to estimate the roll angle in real time. Experimental results show that the system can generate stabilizing torque through the reaction wheel, but performance is limited by actuator response and system delays. Modifications, including compensation for back electromotive force, improve responsiveness and stability. The results demonstrate the feasibility of stabilizing a stationary bicycle using a reaction wheel system, while highlighting practical limitations related to hardware constraints and control implementation.
När digital strategi blir praktik inom fastighetsförvaltning; En fallstudie av digitalisering inom fastighetsförvaltning – hur digitala strategier implementeras i en organisation
(2026) Kellerth, Philip; Ly, Thieu Phu
Digitalisering har blivit en central del av fastighetsbranschens utveckling och ställer nya krav på organisationers strategiimplementering. Studien undersöker hur strategiska intentioner kring digitalisering tolkas och implementeras inom olika organisatoriska nivåer i ett fastighetsförvaltande företag samt vilka faktorer som påverkar implementeringen. Studien genomfördes som en kvalitativ fallstudie av Jernhusen AB baserad på semistrukturerade intervjuer och en enkätundersökning. Resultatet visar att digitaliseringsstrategin tolkas relativt likartat inom organisationen, men omsätts olika beroende på organisatorisk nivå. Ledningen beskriver färdplanen som en strategisk riktning, medan mellanchefer översätter strategin till praktiska arbetssätt. På operativ nivå bedöms digitaliseringen främst utifrån hur väl systemen fungerar i det dagliga arbetet. Digital mognad, fungerande system och informationshantering framträder som centrala faktorer för en lyckad implementering. Slutsatsen visar att implementeringen av digitala strategier inte sker linjärt utan formas genom organisatoriska tolkningar och praktiskt arbete i verksamheten. Studien bidrar därmed med ökad förståelse för hur digital strategiimplementering påverkas av samspelet mellan olika organisatoriska nivåer inom fastighetsförvaltning.
Numerical Study on Centrifugal Compressors for Small Aero Engines. Validation of a Radial Impeller and Diffuser Design for Minimal Frontal Area
(2026) Sandberg, Oliver
Most modern aircraft engines employ multistage axial compressor configurations. However, in small aero engines, axial compressors face substantial challenges. As mass flow is conserved, blade height decreases with each stage, and in small compressors this reduction becomes significant due to end wall boundary layer growth, large tip gap ratios, and pronounced secondary flow effects. An alternative is the use of an axi-centrifugal compressor configuration, where the high pressure axial stages are replaced by a centrifugal compressor. While centrifugal compressors provide higher pressure ratios within a shorter axial length, they introduce challenges related to engine frontal area. The frontal area scales with the compressor pressure ratio and is constrained by the overall engine geometry. The objective of this thesis is to numerically investigate centrifugal compressor design concepts aimed at achieving high aerodynamic performance within a confined space. The NASA High Efficiency Centrifugal Compressor impeller is replicated and validated. Subsequently, four diffuser designs are developed and evaluated using Computational Fluid Dynamics. Vaned diffusers are analysed and compared using standard performance parameters, and the influence of splitter vanes is examined. The results indicate more stable performance for the wedge diffuser compared to the cascade design. Splitter vanes extend and stabilize the operating range of both designs, but at the cost of increased total pressure losses. Due to wake-related issues in the wedge diffuser, the cascade combined with splitter vanes is found to be beneficial. While the goal of achieving significantly higher performance is only partially met, the study provides valuable insights into diffuser design trade-offs for small aero engine applications.
