Machine learning algorithms are experiencing unprecedented attention, but their inherent computational complexity leads to high energy consumption. However, a paradigm shift in computing methods has the potential to address the issue. This shift could be a move towards analog in-memory computing, a method which uses Ohm’s and Kirchhoff’s Laws, and carries out the processing directly where data res

The Arctic heath tundra ecosystem is undergoing rapid transformations driven by climate change, which particularly affects snow accumulation and the length of the growing season. In this study, I examined the influence of snow depth on parameters such as water content, soil temperature, microbial activity, and nutrient availability and investigated their implications for plant water availability a

Titel: Från hierarki till harmoni: Resan mot självstyrande team - En kvalitativ studie om organisationskulturens betydelse för förändringar i en multinationell organisation Universitet/program: Lunds universitet, Service Management Kurs: KSMK65, Examensarbete för kandidatexamen Författare: Eleonora Lundquist & Carolina Runesson Handledare: Ulrika Westrup Syfte: Syftet med denna uppsats är

One hypothesis that attempts to explain dark matter is dark QCD, which suggests that there would be a dark sector made up of dark quarks. Dark quarks would interact with each other through dark QCD similar to how Standard Model quarks interact with each other through Standard Model QCD. Dark QCD would have several QCD-like features, one of which is dark jets. If dark quarks are produced at the LHC

Detektion av ljudanomalier är en viktig pusselbit i strävan mot att nå den fjärde industriella revolutionen. Automatiserad övervakning av industriella maskiner upptäcker fel innan de får förödande konsekvenser. I en industriell miljö finns det ett behov av att ha uppsikt över maskinernas välmående. Erfarna maskinoperatörer lär sig med tiden hur en specifik maskin bör låta och kan identifiera när Traditionally fault detection in industrial machinery has been performed manually by experienced machine operators listening to the machines. However, it is desirable to automate this process to increase efficiency and improve the working environment of the operators. The main challenge in this thesis is to create a system that can accurately detect when an anomalous sound event occurs, at the sam

The field of neural representation of sensory integration is an advanced topic with complex processes. The mechanisms of the brain are far from fully understood and are in need of further development to be implemented in clinical usages such as neuroprosthetics. The purpose behind this project is to further the knowledge of neurotactile integration as well as processes and mechanisms of the brain

This thesis explores the development of a fibre-rich snack using baobab as the primary ingredient. Baobab has gained attention in recent years for its outstanding nutritional composition. The objec-tive of this study was to create a snack that has rheological properties similar to a specified reference product, a nutritional claim regarding its fibre content and has a pleasant flavour. Different s

Sexual dimorphism in the immune system plays a crucial role in disease susceptibility and pathogenesis, yet it is often overlooked in medical and research fields. This study aims to address this knowledge gap by investigating sex differences in immunity at an unstimulated baseline state and in response to Mycobacterium tuberculosis (MTB) stimulation using an in-silico approach. By analyzing single

Deforestation monitoring is of significant importance for the ecosystem, climate change,and policy-making. The availability of optical and synthetic aperture radar (SAR) satellite remote sensing images, along with the development of time series change detection methods, has contributed to the increasing popularity of time series analysis in forest disturbance monitoring. However, there are few stu

This project investigated the impact of beta-glucan on sponge cake's desired texture and physical properties. Sponge cakes with different percentages of Lantmännens PromOat beta-glucan (0.0%, 1.0% and 2.0%) were produced and compared on the following parameters: volume, density, water activity, moisture content and texture profile analyses. These parameters were measured on different storage d

Lung cancer, particularly non-small cell lung cancer (NSCLC), is a leading cause of cancer-related deaths globally. Immunotherapy using immune checkpoint inhibitors (ICI) is a potent treatment for NSCLC; however, long-term response is limited in the majority of patients and there is a lack of predictive biomarkers. Tertiary lymphoid structures (TLS) may serve as biomarkers for predicting ICI respo

This thesis attempts to show tangible ways in which commodification of experience expands into areas outside of direct commercial activity, in contemporary mind and society. The user reviews of Google Maps (URGM) regarding places that don't offer sales of goods and services are being studied empirically, through qualitative text analysis. Functional analysis is also used to study the functions

Sarcoma, a rare and heterogeneous cancer type, present significant diagnostic challenges due to its numerous subtypes. Molecular diagnostics and machine learning models have emerged as promising tools to enhance sarcoma diagnosis. This study, conducted at Qlucore, aims to explore the usage of these new techniques in improving sarcoma diagnostics, with a specific focus on soft tissue sarcomas. The

Currently at Axis, a local role-based access control system is used in devices, which forces the user credentials to be directly installed on the individual devices and the limited selection of roles does not allow for fine-grained access rights. This creates an administrative nightmare in a large scale network and leads to elevated privileges. Instead of this approach a profile based access contr

Inom samhällsplanering har den tekniska utvecklingen medfört att digitala modeller kan användas inom planering av städer och samhällen. Mycket arbete och forskning har fokuserat på digitalisering av stadsmodeller, för att skapa så kallade digitala tvillingar. Digitala tvillingar är digitala kopior som kan användas för att planera och simulera åtgärder i till exempel en stad eller stadsdel. Något sThe digitalisation of processes in societal planning has increased the need for a more standardised approach to the visualisation of geographic information. In recent years a lot of progress has been made with regards to digital models of cities and societies. However, this does not apply to underground data and models to the same extent. The overall objective of this report is to identify areas o

Fem nyckelord: ledarskap, social legitimitet, sociala medier, Twitter, Elon Musk Forskningsfråga: Hur kan ledare använda sig av kontroversiella uttalanden på sociala medier för att skapa och upprätthålla social legitimitet? Syfte: Syftet med denna studie är att skapa förståelse för hur ett kontroversiellt språk och uttalanden på sociala medier, med Twitter som exempel, kan användas för att skapa o

This study explores the idea of flat organizational structures, which are gaining popularity due to their capacity to foster innovation and collaboration. Nevertheless, social interactions inside these organizations can still result in the emergence of social hierarchies, and some employees may hold positions of greater authority and status than others. Therefore, we examine how social hierarchies

This thesis analyses the relation between working hours and four different economic outcomes, productivity, employment, wellbeing, and fertility. The first part of the analysis focusses on regressions of five different measures of weekly average working hours on the economic outcomes, while the second part deals with extensions that makes groups based on average income and mean working hours. Whil

This thesis investigated the perceptions of the identity of the ethnic Chinese minority in Vietnam. During the 2010s, tensions were high in the South China Sea between Vietnam and China, and Vietnamese citizens were taking to the street to express their disapproval of China. This thesis explored the possible repercussion of these geopolitical tensions and aimed to determine whether there is a chan
