Historically, sleep stage classification has relied on manual scoring performed by experienced professionals. In recent years, the emergence of machine learning has enabled the automation of this process, thus saving both time and resources. Many of these sleep staging models depend on data which already has been annotated by a professional, but a few try to exploit the vast amount of unlabelled d
Human Activity Recognition (HAR) from wearable sensors is often constrained by limited labeled data and varying device placements. This thesis investigates a Transformer-based self-supervised approach that learns representations via a masked reconstruction and noise-injection pretext task, followed by fine-tuning on smaller labeled datasets. Experiments on WISDM, REALWORLD, and OPPORTUNITY confir
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
This Master's Thesis examines the possibility of developing a software tool for optimizing offshore wind power plant layouts in regards to wake effects. The study was conducted with the purpose of making development and operation of offshore wind power plants more efficient and cost effective. The tool, named OptiWind, was developed in Python and employs several imported packages for mathemati
S-Rprop is an extension of resilient backpropagation (Rprop), which introduces mini-batch learning to the Rprop algorithm. This is done by using two different mini-batch sizes, one for the learning rate and one for the weight updates, allowing for an accurate learning-rate update whilst gaining the fast weight updates of the stochastic gradient descent (SGD) optimizer. In this paper, the concept o
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
En styrd grundvattensänkning är ett vanligt inslag i byggprojekt där markarbeten sker under grundvattennivån. Under byggtiden sänks grundvattennivån genom att grundvatten pumpas upp genom installerade brunnar. En sänkning av grundvattennivån minskar portrycket och ökar effektivspänningen i jorden vilket medför marksättningar. Storleken på marksättningar beror på avsänkningens storlek och jordegensDuring a construction project where excavation is made beneath the water table, it is common to perform a lowering of the water table. The groundwater can be extracted by installed wells in the stratum of water-bearing soil. A lowering of the water table results in a decreased pore pressure and in an increased effective stress in the soil. An increased effective stress results in ground settlement
Syftet med denna uppsats är att fördjupa förståelsen för New Public Management, ur ett medarbetarperspektiv, med fokus på dess kritik. För att uppfylla syftet med uppsatsen, som utgår från ett socialkonstruktionistiskt perspektiv, har en kvalitativ metod genomförts, varvid en fallstudie och intervjuer genomförts. Den teoretiska referensramen består av tidigare forskning inom fältet för New Public
This Master’s thesis investigates the possibility of adding full vendor-specific software loading sequence support to CANoe, in order to provide the possibility of testing the compliance of Electrical Control Units (ECU:s) from several different vendors to the international standard Unified Diagnostic Services ISO14229-1. Unified Diagnostic Services (UDS) specifies how diagnostic communication sho
MIMO (Multiple Transmit and Multiple Receive) antenna techniques are widely used in the most recent wireless communication standards. For example, LTE (Long-Term Evolution), WiMAX (Worldwide Interoperability for Microwave Ac- cess) and IEEE 802.11n have recently been rolled out across the world. In any communication system, the ML (Maximum Likelihood) receiver provides optimal error rate performan
Branding är en stor business i dagens affärsvärld. Termen används för att beskriva ett företags varumärkeskapitalsuppbyggande åtgärder. Det varumärkeskapital som byggs upp via brandingåtgärder utgör numera ofta en av ett företags mest betydande tillgångar. En tillgänglig möjlighet för näringsidkare att skydda sitt varumärkeskapital är genom generalklausulen i 5-6 §§ Marknadsföringslagen (MFL) som Branding is a big business in todays corporate world and the term is used to describe the work that is done in order to build strong brands. The brand equity that is built by branding often constitutes one of a traders most valuable assets. One possible option for traders to protect their brand equity is through the general clause in 5-6 §§ MFL in which it is stipulated that all marketing actions
Denna uppsats syftar till att, ur ett kritiskt legalitets- och rättssäkerhetsperspektiv, undersöka förarbetens roll vid lagtolkning på straffrättens område, särskilt vad gäller straffmätning. År 2014 ändrades straffet för mord. I lagtextens förarbeten angavs ett tydligt syfte med ändringen: straffet för mord skulle skärpas och livstidsstraff skulle bli ”normalstraffet” för mord i det att det skuThis essay aims to examine the use of legal preparatory works when interpreting criminal law in Sweden. The examination is conducted from a critical perspective with a focus on the principle of legality and the requirement of legal certainty. In 2014 the provision regulating the penalty for murder was altered. The legal preparatory works clearly expressed the purpose of the amendment: the penalt
The effects of climate change and urbanization will increase the risk of flooding in urban areas due to increased precipitation and larger amount of impervious surfaces. Svedala, a municipality in southern Sweden and its storm water recipient Segeå is one area that will be at greater risks in the future. The aim of this study is to compile information about flood risks in Svedala to identify the n
This thesis, written at Scania CV AB in Södertälje, Sweden, during the spring of 2015, treats the subject of Solid State Fuses and the possibility to use these in heavy vehicles. A Solid State Fuse is a device containing only solid state components, implementing a function to protect wiring harness and connectors from damage caused by electrical faults. The device should contain circuit breakers a
Many people suffering from chronic kidney disease are in need of a kidney transplant. A problem in the health care is that patients cannot undergo surgery if they have too much belly fat. Regular exercise and physical activity are therefore crucial for this group of people. A project group at the Skåne University Hospital has recently been established to help patients with chronic kidney disease t
