With diversified requirements and varying manufacturing environments, the optimal production planning encountered in a steel mill has become more flexible and also complicated. The flexibility provides the operator with auxiliary options to satisfy customer requirements through an implementable integrated production planning. In this paper, a mixed-integer nonlinear programming (MINLP) model is fo

In this study, a group of Swedish social media users – politically active as well as “unpolitical” users – are interviewed in focus groups as well as individually about their attitudes towards online political participation, providing a deeper, more informed view of how social media participation works. Sweden, with its high levels of voluntary participation and with an avant-garde position in Int

This thesis aims to address a dual crisis. Globally, the construction industry relies on a linear “take-make-dispose” approach and a “tabula rasa” tactic in each novel project, draining the Earth’s resources. Locally, around a half of residential buildings in Riga, Latvia, are of Soviet mass housing typology. These structures are on the verge of structural expiration, at risk of progressive collap

Digitala D2C-företag i traditionellt fysiska branscher kan etablera en tydlig nisch, men möter nya utmaningar när affärsmodellen ska skalas till fler kundsegment. Detta examensarbete undersöker hur ett svenskt digitalt D2C-företag inom målarfärgsbranschen kan vidareutveckla en validerad, nischad och digital affärsmodell för att nå nya kundsegment på den svenska marknaden. Studien genomförs som enDigital D2C companies in traditionally physical retail can establish a clear niche, but face new challenges when the business model is scaled to broader customer segments. This thesis explores how a Swedish company in the paint industry can further develop a validated, niche-oriented, and digital business model to reach new customer segments in the Swedish market. The study is conducted as a case

Artificial intelligence (AI) is playing an expanding role in infectious disease surveillance and intervention planning by enabling analysis of large-scale health data. One of the key challenges in this area is to characterize transmission within households and to identify factors that influence both infectivity and susceptibility. The present study focuses on the COVID-19 pandemic, which not only

Bygg- och anläggningssektorn står idag för en betydande del av Sveriges totala klimatpåverkan. En del av denna påverkan uppstår i samband med hantering av schaktmassor. Samtidigt ökar kraven för en mer hållbar framtid och en cirkulär ekonomi vilket medför att nya lösningar inom masshanteringen behöver hittas. Syftet med studien är att undersöka vilka hinder och möjligheter som finns för ökad återThe construction sector today stands for a significant amount of Sweden’s total climate impact. One part of this impact arises in regard to excavated soil. At the same time, demands for a more sustainable future and circular economy increase which in turn means new solutions regarding soil management are required. The purpose of this study is to research which obstacles and opportunities there ar

Since the Russian invasion of Ukraine in 2014, the EU and NATO have strengthened resilience, preparedness, and critical infrastructure policies in response to evolving transboundary threats. However, cascading climate risks, defined as cross-border and cross-sectoral impacts intensified by climate change, have the potential to be insufficiently understood and integrated into EU and NATO frameworks

Digital administrative systems are increasingly used in tertiary education. These systems act as the institution’s nervous system by supporting and connecting processes such as registration, attendance, grading, fees, reporting and records. However, the implementation itself does not automatically imply adoption, utilisation or value realization. In heterogeneous educational contexts the same type

Our way of handling the climate crisis is not fast or ambitious enough. We have the opportunity to plan for a better future, not just accept the consequences of our failure. To plan for a better future, we first need to conceptualise a vision of a desired end-point, in this case a climate-neutral and sustainable city. This essay is meant to inspire radical change by using and expanding the radical

This thesis explores experiences of premenstrual syndrome (PMS) and receiving medical treatment for it. Adopting a material-discursive intrapsychic model of thought, the participants' depictions are analyzed through objects, discourses, emotions and internal value systems in order to give various perspectives on PMS as well as contextualize the complex relationship between individual, group, a

Access to digital infrastructure in highly digitalized societies is shaped not only by the availability of technology but also by the administrative arrangements that govern access to it. This study examines how non-EU international students at Lund University experience and navigate exclusion from Sweden’s digital financial infrastructure through the case of Swish, a mobile payment system widely
