Wood is increasingly being recognized as one of the most promising building materials on the market as a result of environmental challenges. Aside from the fact that wood is a sustainable material, it has the benefit of being high-quality, strong, flexible, and speedy to construct, which makes it a much more attractive material compared to its less sustainable counterpart. The latest computational
Begreppet rättssäkerhet används ofta både inom och utom den rättsvetenskapliga sfären. Eftersom man inte sällan möter det i den allmänna debatten i Sverige, syftar den här uppsatsen till att undersöka om begreppet i det sammanhanget används i samma betydelse som inom rättsvetenskapen. Undersökningen tar avstamp i vad framstående svenska rättsvetare har uttryckt ifråga om att definiera begreppet r
This thesis will explore the use of AWS machine learning services that enable natural language processing (NLP). More specifically, this work will focus on sentiment analysis of product and service reviews written in Swedish. To find the most efficient solution to this task, the ready-made sentiment analysis tool available on AWS (Amazon Comprehend) was compared to custom-made solutions built on t
Arbetet är en lek med tanken, att få låna en plats som idag står i limbo mellan att vara ett slutet industriområde och den tänkta framtida exploateringen. I arbetet beskrivs hur Oceanhamnen i Helsingborg inom ramarna för visionen H+, har gått från att ha varit ett slutet industriområde, till att bli en aktiverad plats i staden. Lokala, regionala och riksintressen står mot varandra och skapar ett m
Machine calibration is important for optimal performance throughout the lifespan of industrial processes. A prime example is the pick-and-place process, where robots must manipulate objects accurately. Currently, this process is manually calibrated, which can be a complex practice. This thesis studies a software-based approach to error detection within the process, aiming to reduce the need for ma

Energy harvesting enables products to become more self-sufficient of power and offers the possibility to avoid battery exchange and power cables. The performance and applicability of the most promising or popular small scale energy harvesting technologies are investigated in this thesis. The focus lies on the amount of potential energy that can be harvested and how limited the technology is to a s
This report has investigated which type of risk analysis methods that can be used in an early design phase in a unique facility from a time and quality perspective. Two planned underground facilities for the HL-LHC at CERN have been used as a case study. The methodology is an action research study with information gathered from a literature study and survey. Six different risk analysis methods hav
One way to increase the flexibility of industrial robots in manipulation tasks is to integrate additional sensors in the control systems. Cameras are an example of such sensors, and in recent years there has been an increased interest in vision based control. However, it is clear that most manipulation tasks can not be solved using position control alone, because of the risk of excessive contact f
Systems with structural resonances are difficult to control if fast responses are required. Rapid changes in the control signal may excite the resonant modes. In digital control with zero-order-hold sampling there will be very rapid changes in the control signal. A way to deal with the problem is to use predictive first-order-hold sampling instead. The control signal is then linear between the sam
Since the beginning of wireless communication, one of the central problems has been resource management and maximization of network throughput. Solving these recurring issues is an important topic in the field of wireless communication to increase application options and the user experience. The existing methods for solving the issue of inter cell interference by maximizing the network capacity ar
Sedan den första generationen av mobila nätverk lanserades i början av 80-talet har en ny generation utvecklats ungefär vart tionde år. Med ett alltmer digitaliserat samhälle har användningen av de mobila nätverken ökat drastiskt. Ökningen ställer nya krav på nätverkens kapacitet där den senaste generationen, 5G NR, är utvecklad för att tillgodose dagens och kommande års behov. Dessa behov innefatAs the demand for higher data rates and lower latencies increase, together with the use of higher frequency bands, MIMO and beamforming have become an essential part of the 5G NR technology. Calculating the beamforming weights is a costly process, and reducing the frequency resolution of the weight calculations would save a significant amount of computational power. Which resolution is suitable to
Använda immateriella rättigheter för att öka ett företags hållbara påverkan Immateriella rättigheter är verktyg för att stimulera innovation och investeringar i forskning och utveckling för att främja tillväxt och har traditionellt använts för ekonomiska intressen före miljömässig och social påverkan. Forskningsprojektet IPACST, som forskar på immateriella tillgångars roll för att accelerera en hIntellectual Property Rights, IPR, are tools to incentivize innovation and investment in Research and Development (R&D) to promote growth and are traditionally used for economic interests before environmental and social concerns. The research project IPACST has developed a business tool kit for supporting organizations in designing their IP models to increase environmental and social impact. T
One of the core purposes of the Swedish “nämndemannasystem” is to act as representatives of the public in the court systems. The representation aspect of the “nämndemannasystem” has though been declared non-existent or too weak by previous research and the general debate in society, on the ground of its pictorial composition. However, the concept of representation is not that simple as depicted by
För att kunna handskas med de stigande stressnivåerna hos skolelever är det viktigt att skapa en välfungerande lärandemiljö. Detta kan till exempel göras med olika verktyg och ett av dem är Woof Technologies ApS platform WOOF som kan användas som ett hjälpmedel för lärare i grundskolan för att mäta och arbeta med elevers trivsel och välmående i en klass. Syftet med detta arbete är att analysera ocIn order to deal with the rising stress levels of pupils, it is important to create a well-functioning learning environment. This can for example be done with various tools, one of them being Woof Technologies ApS platform WOOF which can be used as an aid for teachers in elementary school to measure and work with students' well-being in class. The purpose of this thesis is to analyze and eval
Landscape fragmentation and habitat loss are detrimental to biodiversity, affecting highly specialised species the most. Species distribution models usually require either solid knowledge about the ecological niche of the species or spatial distribution data. Many endangered species have, how- ever, a relatively unexplored ecological niche in combination with a very small area of distribution. A m
I takt med att den digitala arbetsmiljön växer måste kraven på användbarhet och tillgänglighet tillgodoses.

Momentum or trend following investing refers to trading strategies constructed around the idea that in financial markets, the current trend will, more often then not, prevail. In the context of asset prices, this means that previous returns or the price development of an asset is indicative of similar future returns and price development. While at odds with established theory such as the weaker fo
Dressed Gluon Exponentiation (DGE) is used to calculate the thrust and the heavy-jet mass distributions in e + e - annihilation in the two-jet region. We perform a detailed analysis of power corrections, taking care of the effect of hadron masses on the measured observables. In DGE the Sudakov exponent is calculated in a renormalization-scale invariant way using renormalon resummation. Neglecting
