Vital societal functions and critical infrastructure rely to an increasing extent on services from space, such as navigation and positioning systems, timekeeping, and communications. However, understanding of space service dependencies is low among practitioners and society at large, with research on societal space dependency being limited as well. In order to avoid cascading effects from disrupti
Danske Bank has for several years modeled customer purchase behavior on category level (e.g. savings or investments). This thesis is a first attempt at predicting (first time) customer purchase behavior on product level. Five products within two categories were chosen and modelling was done with python using gradient boosters (mainly XGBoost, but also Light GBM). Results indicated that predicting
Of the food produced for human consumption, one-third is lost or wasted. Food waste has an impact on the environment in several ways and it is thus required to reduce food waste in all parts of the value chain. The objective of this thesis is to identify drivers and barriers for implementing food waste reducing strategies in school kitchens. The study is conducted within the project Göteborgsmod
Dividing wall columns are single shell distillation columns which are thermally fully coupled. DWC has the ability to create three product streams from one feed stream. A simulation of DWCs is hard due to the complexity of the system. Unfortunately, there is no good software package that can be used for simulations. Instead a detailed flowsheet with the right components and good arrangement over t
In this thesis, we study the Jarrow and Yildirim framework for inflation modeling and provide a new specification based on spread modeling which allows to calibrate the model to Zero-Coupons and Year-on-Year options jointly with convexity adjustments. We use this model to provide closedform formulas for options volatilities, convexity adjustments and Year-on-Year swaptions prices. Calibration resu
Reco Port AB is a company that builds folding garage doors and is a part of the ASSA ABLOY group. Reco uses Styrofoam as insulation in their doors and their current solution of cutting the Styrofoam is using a plunge saw and a custom built table to hold the Styrofoam in place. The solution is not ergonomic and spreads a lot of debris of Styrofoam around the workstation. Due to this it was requeste
Today, most software systems are event-driven, meaning that code execution is triggered by events handled dynamically. A typical example is a graphical user interface, where a button click initiates a specific action. In contrast, classic automation systems rely on programmable logic controllers, which execute code periodically at fixed intervals. The purpose of this study is to compare periodic a
The existing Power Supply Unit (PSU) at Axis Communication contains a fully discrete solution that lacks flexibility for future updates. This research aims to address critical challenges by exploring methods to enhance speed, reduce PCB area, and introduce flexibility to the existing hardware solution. The approach involves replacing hardware functionalities within the control unit with software-c
The European Union regularly portrays itself as a normative power committed to values such as human rights, solidarity, and the rule of law, while the EU Turkey Statement of 2016 has raised questions about the coherence between this self-image and the EU’s external migration practices. This thesis investigates how the Statement is linguistically legitimised in political and media discourse, as
I juni 2023 presenterades SOU 2023:36. Betänkandet syftar till att utreda frågan om hur EU-kommissionen och Rådets direktiv om tillräckliga minimilöner i Europeiska unionen ska implementeras i den svenska rätten. Betänkandet har bemötts av viss kritik i remissvar från berörda aktörer och experter inom området. Främst med anledning av hur betänkandet behandlar frågan om enskilda rättigheter samt tä
The aim of this bachelor degree project is to design a modular luminaire with a longer lifespan, in order to reduce consumption. The project aims to explore how design can contribute to sustainable development by creating a durable and adaptable lighting solution. The luminaire is versatile and can either be hung from the ceiling, mounted on the wall, or placed on a table. It can be expanded
The efficiency of combustion engines is crucial for their future development, prompting researchers to explore various factors to enhance performance. Among these factors, exhaust gases hold significant potential. Typically, exhaust gases carry about 30-40% of the engine's energy, which often remains underutilized. Although technologies like turbochargers have made progress in recovering some
Digital integrated circuits are fundamental to modern electronic devices, with increasing design complexity requiring robust verification methods to ensure error free functionality. This thesis examines the critical role of formal verification in digital Integrated Circuits (IC) design, particularly during the architecture modeling phase. Using a state machine module that controls clock frequency
Computed tomography (CT) segmentation models are frequently used within radiotherapy treatment planning, but similar models are not available to the related imaging modality cone beam computed tomography (CBCT) due to the scarcity of labeled data from this domain. Such models could have multiple clinical applications whereby it is of interest to study whether the CT segmentation models can be adap
Enligt den Europeiska konventionen om skydd för de mänskliga rättigheterna och grundläggande friheterna (EKMR) krävs jurisdiktion för att en avtalsslutande part ska kunna hållas ansvarig, när ett påstående om intrång av non-refoulement enligt EKMR uppstår. Stater genomför extraterritoriella gränskontroller för att kontrollera migranter och internationella flyktingar utanför statens egna territoriuAccording to the European Convention on Human Rights, jurisdiction is a prerequisite for holding a contracting state responsible when an allegation of infringement of the ECHR arises, such as the principle of non-refoulement. States implement extraterritorial migration management measures trying to avoid triggering the principle of non-refoulement arguing that it cannot be applied extraterritorial
Training Generative Adversial Networks (GANs) for image synthesis problems is a largely heuristical process that is known to be fickle and difficult to set up reliably. To avoid common failure modes and succeed with GAN training, one needs to find very specific hyperparameter settings carefully tuned to the model architectures and datasets at hand. Standard GAN training optimization methods such a
Power reduction is becoming a critical design requirement for ASIC/SOC designers. Reducing both dynamic and leakage power is essential to meet power budgets for portable devices as well as to ensure that these ASICs meet their packaging and cooling costs. In addition, the power of an ASIC has a significant impact on its reliability and manufacturing yield. Also, low-power has become a leading des
Multi-storey buildings constructed in timber have become more common in recent years. A reason for this lies in the growing interest for sustainable building, where timber is seen as a particularly interesting alternative. As efforts have been made to improve the heat insulation in buildings, the energy consumption from manufacturing materials and from constructing buildings, referred to as embodi
Title: Identification and suggestions of emerging technologies for a smart warehouse Authors: Xinchuan Li, Monish Ashok Kumar Background description: The warehouse is a crucial point and one of the most vital logistics and supply chain management links. Warehouses are built to smooth the supply chain and can be divided into different classifications. The importance of warehouses has increased a lo
