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
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
During this thesis nanoporous alumina has been used as a template for the synthesis of nano-confined palladium structures. The nanoporous templates have been synthesized by anodization of aluminum and characterized using atomic force microscopy (AFM), scanning electron microscopy (SEM) and small angle X-ray scattering (SAXS), resulting in good statistics of the pore diameter and interpore distance
This thesis seeks to explain constraining effects of distance to markets on agricultural smallholder’s ability to commercialise, using Zambia as a case. Despite a growing consensus that inaccessible markets constrain the development of broad-based agricultural growth, creating socio-economic regional disparities, the exact nature by which distance and market access interact with agricultural produ
In an age of increasing usage of heavily interconnected platforms, graph databases have increased in popularity due to their ease of modelling these systems. This thesis will evaluate if the graph database Neo4j can be used to model Lime's CRM System efficiently by comparing the performance of Neo4j and MS SQL on queries similar to those existing in Lime CRM. To benchmark the databases, they w
Detta project utfördes i samarbete med svenska förpackningsföretaget Tetra Pak Packaging Solutions AB. Deras huvuduppgift är att utveckla förpacknngsmaterial, processer och maskinlinjer som krävs för att producera laminatet, vilket är att flerskiktsmaterial som vanligtvis består av papper, plast och aluminium för att skapa en stark och skyddande barriär för flytande livsmedel. För att skapa laminaThis project was carried out in cooperation with Swedish packaging company Tetra Pak Packaging Solutions AB. Their main purpose is to develop the packaging material, process, and machine lines needed to produce the laminate, which is a multi-layered material typically made by combining paper, plastic, and aluminum to create a strong, protective barrier for liquid food packaging. In order to create
Menstrual health is essential for people who menstruate to fully participate in daily life and social activities. It is also a fundamental human right that closely impacts the realization of other rights such as right to non-discrimination and education. In recent years, there has been increasing attention to menstrual health on both the international and national levels. However, significant barr
NMDA receptors are ligand-gated ion channels assembled as heterotetramers composed of glycine-binding GluN1 and GluN3 subunits (GluN3A-B), and glutamate-binding GluN2 subunits (GluN2A-D). Their involvement in various psychiatric and neurological disorders makes them potential therapeutic targets. However, compared to the extensively studied GluN1/2 NMDARs, the functional, physiological, and pharma
An optical system for digital light processing car headlamps was designed and optimized in this project. The specifications include five lens elements and a field of view of 15 degrees horizontally and 7.5 degrees vertically. The system consists of an illumination module and a projection lens assembly. A high-brightness LED source and a rectangular light integrator ensure uniform illumination on t
Emerging storage devices, particularly ferroelectric tunnel junction (FTJ) memristors, offer a compelling solution for high-density storage as they form a type of non-charge based non-volatile storage capable of storing multiple bits in each device; however, their adoption is hindered by reliability concerns. This work addresses this by presenting a design and implementation of an efficient Error
This thesis investigates the performance of two model predictive control (MPC) variants for autonomous racing, using a 1:10-scale vehicle as a testbed for reference path-tracking experiments. The platform is equipped with a single inertial navigation system (INS) sensor, providing highly accurate odometry measurements. The controllers under study are the standard gradient-based MPC and a sampling-
This thesis explores advancements in Automatic Speaker Verification (ASV) by examining the impact of multiple speaker enrollments and introducing Adaptive Neural Probabilistic Linear Discriminant Analysis (Adaptive NPLDA). Modern ASV combines front-end feature extraction, using state-of-the-art methods based on Deep Neural Networks (DNNs), such as the ReDimNet architectures, with back-end modeling
This thesis presents a pipeline for automated object identification and dot based annotation in User Generated Content (UGC) images. The need for this type of model is motivated by IKEA’s digital product ”Content Recommendations” which aims to enhance customer engagement through shoppable UGC images and addresses the challenge of detecting specific products in various, real-world visual contexts.
With the rapid advancement of urban renewal and the shift toward sustainable development, the integration of Transit-Oriented Development (TOD) and industrial heritage preservation has become a key strategy in revitalizing post-industrial cities. Rather than viewing industrial heritage sites as obsolete, new approaches now emphasize their adaptive reuse within the framework of transit-accessible,
