Most secondary school curriculums in the world don’t include semiconductor physics. The fact that it is not included is considered a mistake by many physicists and engineers, considering it is a massive part of modern technology. Amongst these technologies are transistors, LED:s, screens and solar cells. This thesis attempts to use solar cells to give an example of how semiconductor physics can be
This thesis presents an open and documented replacement for the two-tank water level laboratory used to teach PID control at LTH Helsingborg. The existing system depends on a proprietary, closed-source Windows application and a legacy data acquisition card, tied to an ageing Windows XP-era PC that cannot be modified, documented, or used remotely. The new platform pairs a Raspberry Pi Pico W microc
Direct-to-Device (D2D) communication in Non-Terrestrial Networks (NTNs) enables smartphones to connect directly to satellites, extending wireless coverage beyond terrestrial networks. This thesis presents the design of a smartphone antenna optimized for NTN operation, followed by a link budget analysis and Electromagnetic Field (EMF) exposure assessment. The proposed solution is a dual-band circu
Titel: Från prestationsmått till handling Seminariedatum: 2026-06-04 Kurs: FEKH69, Examensarbete i redovisning på kandidatnivå, 15 hp Författare: Isak Tranberg-Hansen, Markus Truong, Tilda Lundberg Handledare: Johan Dergård, Caroline Hellström Nyckelord: prestationsmätning, prestationsmått, ekonomistyrning, tillverkningsföretag, prestationsmätningssystem Forskningsfråga: Hur utformas och används p
The Copernicus High Resolution Vegetation Phenology and Productivity product (HR-VPP) has been operational for several years and has been used by various institutions to assess crop growth conditions and estimate crop yield. However, studies focusing on winter-growing crops, especially winter wheat, remain limited. HR-VPP is based on the Plant Phenology Index (PPI). In theory, PPI is expected to p
Unsaturated soil water flow is commonly described by Richards’ equation, a nonlinear PDE that is typically solved using numerical methods. In this thesis, two alternative physics-informed machine learning approaches are investigated for forward and inverse modeling of unsaturated flow. First, physics-informed neural networks (PINNs) are applied to approximate solutions of Richards’ equation in a o
Bakgrund: Psykisk ohälsa är ett växande problem. Djurkontakt har visat på positiva effekter på människors hälsa. Djurassisterade interventioner används inom vård och rehabilitering för att främja hälsa och välbefinnande genom meningsfulla aktiviteter tillsammans med djur. Djurassisterade interventioner har visat sig bidra till ökad delaktighet i vardagliga aktiviteter samt social interaktion. Syf
As digital systems built on integrated circuits (ICs) increase in size and complexity, the required verification effort increases to ensure functionality in modern systems. To achieve sufficient granularity in verification infrastructures, the system is commonly tested both as separate parts, on block/unit level, and when the parts are connected, on integration level. With the goal of reducing the
Cyanobacterial blooms and bottom-water hypoxia have long been studied and connected to the eutrophication in the Baltic Sea. This thesis investigates the dynamic of the spatiotemporal correlation between cyanobacterial summer bloom and dissolved oxygen at the sea floor in the Western Gotland Basin, as per defined by HELCOM 2022. The thesis is conducted using weekly and monthly data from 1998 to 20
The regulatory oversight in Sweden is based on chapter 26 of the Swedish environmental code, together with national environmental goals. Even though there are guidelines the municipalities carry out the oversight in different ways. The aim of this study is to examine how municipal environmental supervision in the waste sector is carried out, and to analyse which legal and organisational factors en
This thesis examines the lived experiences of women in Rosengård, Malmö, a neighborhood that has been labeled as dangerous in Swedish public discourse and categorized as an “especially vulnerable area” by the Swedish police in 2015. Rosengård bears a stigmatized reputation based on negative media representation, institutional labeling and both political and public discourse. Drawing on eleven semi
Syftet med denna studie har varit att undersöka looksmaxxing och hur det presenteras på sociala medieplattformen TikTok. Studien avser att analysera hur looksmaxxing presenteras som självförbättring och maskulinitet. Det empiriska materialet har hämtats från ett nytt TikTok-konto från utforska-sidan genom att söka efter “looksmaxxing”. Därifrån har de åtta inläggen som presenterades hämtats. För a
Syftet med denna studie är att öka kunskapen om mellanchefers roll i organisatoriska förändringar. Studien fokuserar särskilt på hur mellanchefer nära den operativa verksamheten upplever, tolkar och hanterar förändringsarbete i praktiken. Studien utgår från teorier om meningsskapande och organisatoriskt lärande för att analysera hur mellanchefer tolkar förändringar, hanterar osäkerhet och skapar f
This thesis examines the profitability effects of a systemic supply chain disruption such as COVID-19 through the inventory intensity and supply chain exposure levels of affected firms. Prior research has largely explored these aspects separately, whereas this thesis combines inventory and exposure variables to investigate both their individual and joint effects. Using a sample of US-based publicl
Bakgrund - Samarbete mellan offentliga och privata aktörer är avgörande för livsmedelsberedskap, men tidigare forskning visar att implementeringen av samverkansmekanismer kan påverkas av organisatoriska, relationella och institutionella faktorer. Det finns behov av ökad förståelse för hur dessa mekanismer fungerar i praktiken. Syfte - Syftet med studien är att undersöka vilka samverkansmekanismerBackground - Collaboration between public and private actors is crucial for food preparedness, but previous research shows that the implementation of collaborative mechanisms can be influenced by organizational, relational, and institutional factors. There is a need for increased understanding of how these mechanisms function in practice. Purpose - The purpose of the study is to examine which col
This qualitative study aims to analyze how a smaller municipality in Sweden works on crime prevention where the recruitment of children into gang crime is in focus, due to the large increase in the recruitment of children and young people. The study is based on semistructured interviews of people who work within the municipality regarding crime prevention work. The study is also based on a content
Dagens samhälle rör sig mot en alltmer elektrifierad och grönare värld. Detta medför betydande förändringar för Sveriges elsystem. En växande andel väderberoende produktion, såsom vind och solkraft, skapar en ojämnare och mer oförutsägbar elproduktion än tidigare. Ökad elektrifiering av industrisektorn leder till högre efterfrågan på el, och antalet elbilar ökar, vilket förändrar både transportsek
Pork makes up around 30 % of the overall meat consumption. Pig production has an impact on the environment, and its impact depends mainly on the feed used. Agriculture in general has impacts both on the climate and biodiversity. Since animal products’ consumption are increasing it is of interest to assess its environmental impact. This study aims to assess two pig feeds’ environmental impact throu
