Att utforma en vårdcentral för en god patientupplevelse
(2026) Emilsson, Amanda; Landin, Linnea; Möller, Andréa; Svantesson, Alma; Wigren, Ida; Yu Hammarsten, Linnea
This thesis explores how healthcare centres can be designed to enhance the overall experience for patients. The purpose of this project is to create an understanding of the patient experience and the interplay between the digital and physical elements at healthcare centres. The project focuses primarily on the physical experience, but with the digital platforms in mind. The project began with user studies and literature searches to create an understanding of how healthcare centres work, but also to collect data on what patients find important at a healthcare centre. Based on the collected data, twelve design guidelines were created of how healthcare centres can be designed to enhance the patient experience. The guidelines are divided into five different categories: Navigation and flow, Recognition, Pleasant atmosphere, Comfort and Protection and privacy. With the guidelines as a starting point, a concept was created to exemplify how the guidelines can be implemented to design a healthcare centre to achieve a good patient experience. A conclusion of the project is that patient experience involves more than the given care and is, to a great extent, influenced by the design and atmosphere of the waiting room.
Minimalistisk Cruise Control
(2026) Basusta, Ilayda; Eriksson , Astrid; Kuang, Silja; Lundquist, Lisa; Nordhage, Filip; Tran, Jenny
Cruise Control and its associated functions are essential tools for modern truck drivers, particularly during long-distance hauls. This project aims to make the use of the Cruise Control system more attractive for both experienced and novice drivers by developing a minimalist and less complex user interface. The final result is based on the insights and identified requirements obtained through user studies, supported by theories and principles in usability and user-centered design. It can be concluded that there is a significant need for the interface to be intuitive enough for drivers to navigate during first use, and the system’s functions must be clearly defined. The final product is therefore characterized by clear system structure and direct interaction pathways. Based on the work conducted, conclusions can be drawn regarding learning, interaction design, and driver needs.
Development and optimization of atomic layer deposition nanolaminate protective coatings
(2026) Volta, Lorenzo
Protective coatings for metallic mirrors must resist environmental and chemical degradation while preserving the reflectance of the underlying surface. Atomic layer deposition (ALD) provides the precise thickness control and conformality required for ultra-thin protective barriers. However, plasma-enhanced ALD (PEALD) exposes oxidation-sensitive metallic substrates to reactive plasma species, while single-layer coatings may remain limited by material-specific properties and growth defects. This work develops and optimizes PEALD oxide nanolaminate coatings deposited at 150 ˝C for the protection of silicon, silver, aluminium, and gold mirror substrates. An Ar/H2 plasma pretreatment (50W, 2% H2, 60 s) was selected as providing suitable surface preparation while causing minimal optical and morphological modification. Silver was identified as the most oxygen-sensitive substrate, with its reflectance at 532nm decreasing by more than 25% after only 30 s exposure to a 50W O2 plasma. A thermally deposited Al2O3 interlayer was therefore introduced to protect the substrate during subsequent PEALD processing. A thickness of 4nm suppressed the plasma-induced reflectance loss comparably to 8nm while limiting optical interference. Nanoscratch testing further showed consistently higher first critical loads for Al2O3 than for a PEALD AlN interlayer across all investigated substrates. Five 50 nm single-layer oxides, Al2O3, SiO2, TiO2, HfO2, and Ta2O5, were screened under HCl and KOH exposure using reflectance measurements and visual inspection. Based on this screening, SiO2, TiO2, and HfO2 were selected for nanolaminate development. TiO2/SiO2 and HfO2/SiO2 architectures with individual layer ratios of 1:1, 5:5, 4:1, and 1:4nm were subsequently evaluated in 10 wt% HCl for exposure times of up to 90 min. TiO2/SiO2 nanolaminates showed superior overall performance compared with HfO2/SiO2, while SiO2-rich architectures provided the highest chemical stability. In particular, the 1nm TiO2:4nm SiO2 architecture provided the best balance between reflectance preservation, resistance to delamination, and chemical protection. Comparison of total coating thicknesses of 25, 50, and 100nm identified 50nm as the most suitable compromise between protective performance and preservation of optical properties. Potentiodynamic polarization measurements in 0.1M HCl and electrochemical impedance spectroscopy in 0.1M citric acid at pH 5.2 further supported the favourable barrier performance of the selected architecture, which exhibited low current densities and impedance magnitudes on the order of 107 Ω–108 Ω. Overall, the results demonstrate that combining complementary oxides within a controlled nanolaminate architecture can improve the chemical protection of metallic mirrors while maintaining their optical functionality.
Design Thinking for Social Innovation in Rural Mozambique
(2026) Andersson, Emma; Samin, William
Rural communities in Sub-Saharan Africa face ongoing challenges related to poverty, limited infrastructure, and restricted access to markets. In small-scale fisheries women play an important role in post-harvest activities, yet their work is often informal and constrained by limited resources. In Linga Linga, Mozambique, these challenges are reflected in the short shelf life of fish, limited use of available fish resources, and limited opportunities for value creation. This study explores how the design thinking process can support value creation for female entrepreneurs in rural Mozambique. It also examines to what extent the resulting solutions contribute to social innovation, understood through the dimen sions of addressing human needs, changes in social relations, and empowerment and agency. The research is based on a qualitative case study conducted in collaboration with the non-profit organization Project Vita. Data were collected through a two-month field study, including observations, semi-structured interviews, surveys, and participatory methods adapted to the local context. Design thinking structured both the fieldwork and the analysis through the stages of empathize, define, ideate, prototype, and test, while social innovation served as the analytical lens. The study resulted in four contextually grounded solutions: fish powder, fish samosas, raised drying racks, and solar tent dryers. These solutions address immediate needs related to fish preservation, food security, and income generation, showing a strong contribution to the dimension of addressing human needs. However, their impact on social relations and empowerment is more limited, reflecting the difficulty of achieving broader structural change within a short time frame and in a resource constrained setting. Based on these findings, the study develops a conceptual model that not only illus trates how different stages of the design thinking process contribute unevenly to the dimensions of social innovation, but also proposes how aspects of social relations and empowerment can be more deliberately integrated into short-term, resource constrained design processes
Steel construction change orders: causes and strategies
(2026) Forsberg, Simon; Nyberg, Selma
Construction projects are characterised by high uncertainty, making changes and adjustments a recurring feature of project execution. These deviations are commonly formalised through change orders, which alter contracts through additions, omissions, or modifications to the agreed work. Although change orders are often necessary, they can negatively affect project performance through rework, delays, increased administration, cost increases, and strained relationships. This study investigates the main causes and effects of change orders in the steel construction industry and explores strategies for reducing their occurrence and mitigating their negative effects. The study is conducted as a qualitative single-case study at a Swedish steel construction company. Empirical data collection is carried out in three phases through unstructured interviews, observations, a workshop, semi-structured interviews, and a group interview. A literature review was performed to identify causes and effects of change orders in previous research, which were then combined with empirical findings to develop a taxonomy tailored to the steel construction context. The taxonomy is structured into three levels, consisting of two categories, 10 themes, and 27 factors. To support managerial prioritisation, the causes are assessed in a risk matrix based on the severity of impact and probability of occurrence. This resulted in six high-risk factors critical to address: communication, coordination, inexperienced project manager, client generated changes, documentation, and controversial change orders. The first three of these factors are identified as preventable and the other three as non-preventable. Strategies are then presented for managing them accordingly. The study contributes by providing an operationally focused taxonomy of change order causes and effects tailored to steel construction, as well as practical strategies for supporting more structured change order management.
