This study investigates the feasibility of producing and utilizing biochar as a soil improver in a rural village in Mozambique. It consists of the following two parts, a field study in Mozambique and a theoretical and laboratory study in Sweden. The field study was performed at Project Vita in Linga Linga, Mozambique, which is a non-profitable organization, and the study in Sweden consists of a li

Vågkraft är en energikälla som på många sätt sticker ut från andra förnybara energikällor. Å ena sidan har havsvågor en helt annan regelbundenhet än till exempel vind eller solsken och har därför potentialen att utgöra en mycket mer tillförlitlig energikälla än dessa. Energiinnehållet i världens havsvågor är dessutom oerhört stort och jämförbart med världens totala förbrukning av elektricitet. Å aWave power is a type of renewable energy which holds great potential, but this potential remains largely unused due to difficulties in implementing commercially viable wave energy converters. This study uses Monte Carlo integration to optimize and estimate the electrical power output of a Simulink model based on a real wave energy converter developed by Waves4Power. For 78 sea states defined by th

Bygg- och fastighetssektorn stod ungefär för 34 procent av Sveriges totala energianvändning år 2021. Energianvändningen inom sektorn är främst energin som går åt till uppvärmning. 2021 stod uppvärmningen för ungefär 73 procent. (Boverket, 2024a) Hur brukarna i en byggnad beter sig kan vara en viktig parameter i energianvändningen. Att göra omfattande renoveringar för att förbättra byggnadens energThe construction and real estate sector in Sweden accounted for about 34 percent of the country's total energy usage in 2021. However, within this energy consumption lies a variable influenced not just by building design or technology but by the behavior of its occupants. Behavioral patterns, such as window opening habits, hot water usage, electricity consumption, and temperature adjustments,

The beverage packaging industry is growing rapidly, driven by urbanization and changing lifestyles. Demand for packaged beverages with extended shelf life is driving sales of products with superior barrier properties, due to the high environmental impact of food waste compared to packaging waste. Despite progress, packaging waste represents more than a third of total waste. Thus, milk and plant-ba

Utveckling av förenklade modeller för tryckinducerade flöden i smala kanaler med plötslig expansion Denna masteruppsats är gjord i samarbete med företaget FS Dynamics Sweden AB, som är specialiserat på datorsimuleringar, vilka används för att analysera och förstå komplexa problem. Denna uppsats har som syfte att utveckla en metod för att effektivisera simuleringar av luftflöden i smala och långa Simulations of domains with large differences in length scales across different directions are often computationally expensive because they require high mesh resolution, leading to long simulation times. This master’s thesis was done in collaboration with FS Dynamics Sweden AB and addressed the high computational cost associated with fully resolved 3D simulations. Inspired by semiconductor and ele

The construction sector is responsible for around 40 % of all generated waste in Sweden and is also responsible for around 21-22 % of all carbon emissions. In a sector that is responsible for a substantial part of Sweden’s climate footprint, it’s important to find solutions to the negative effects towards the climate. Much of the generated waste comes from building and demolition waste which ends

Attracting tourists from all over the world throughout the year, the flourishing of mass tourism in Bali has been perpetual for the last few decades. As both domestic and international tourists increase over time, the demand for built-up areas increases accordingly, which has caused urban expansion exploiting vegetated areas, especially agricultural lands. Consequently, this tourism-led urbanizati

This Master’s thesis evaluates and validates a newly developed risk assessment tool designed for performance guarantees in the sales of rock crushing solutions at Sandvik Rock Processing Solutions, Stationary Crushing & Screening (Stat. C&S). The research aims to compare the new tool against the current expert-based method, assess the relevancy of the variables included, and propose necess

I takt med att personer med funktionsnedsättningar och variationer ökar blir tillgänglighet i digitala system och miljöer allt viktigare. Lagen om tillgänglighet till digital offentlig service trädde i kraft 2019 och ställer tillgänglighetskrav på informationssystem och digitala tjänster inom den offentliga sektorn. Långt ifrån alla myndigheter och offentliga institutioner lever upp till dessa kra

Title: Reconfiguring a Unit-Load Finished-Goods Warehouse Authors: Jakob Bjarke & Oliver Elftonsson Supervisor: Joakim Kembro, Department of Industrial Management and Logistics, Faculty of Engineering, Lund University Problem formulation: Since moving, Alfdex has experienced increased demand while the Finished Goods Warehouse (FGW) has remained unchanged. This has caused challenges such as

Skolan har en brottsförebyggande funktion. Genom att forma normer och värderingar hos elever kan skolan motverka beteenden och uppfattningar relaterade till brott och kriminalitet. Skolan kan även uppmärksamma och förhindra normbrytande beteenden som kan innebära en ökad risk för avvikelser senare i livet. För att skolan ska kunna ha en brottspreventiv verkan är det dock avgörande att eleverna när

This paper focuses on constructing models that predict a Value at Risk (VaR) estimation for financial portfolios using hierarchical clustering and copulas. Traditional VaR models often assume linear dependencies and normal distributions, which can be poor assumptions for financial data - especially during extreme market events. This paper introduces a non-linear modeling approach using copulas to

Examensarbetet gjordes i samarbete med La Isla Network (LIN), en icke vinstdrivande amerikansk organisation som bekämpar konsekvenserna av yrkesrelaterad värmeexponering. Värmestress utgör ett betydande hot mot individer engagerade i fysiskt arbete under varma förhållanden, med potentiellt dödliga konsekvenser. För att minska dessa risker har LIN utvecklat programmet RSH-S (Rest, Shade, Hydration,The thesis was done in collaboration with La Isla Network (LIN), a US-based non-profit organization dedicated to combating the consequences of occupational heat exposure. Heat stress poses a significant threat to individuals engaged in physical labor in warm conditions, with potentially fatal consequences. To mitigate these risks, LIN has developed the RSH-S (Rest, Shade, Hydration, and Sanitation

Purpose: The purpose of this study was to understand how platforms of mental health influence people’s decision to engage in online therapy through their marketing strategies implemented throughout the customer journey. Theoretical perspective: This study is rooted in two theoretical models, the customer journey and the Theory of Planned Behavior (TPB). Specifically, the customer journey will ser

Despite the current recognition and discussions surrounding corporate sustainability, the topic remains highly complex, with significant uncertainties regarding how to integrate sustainability into daily operations. Hence, it becomes increasingly important for managers to develop a comprehensive understanding of how to implement corporate sustainability strategies. Therefore, this thesis investiga

This thesis investigates the perception of prominent syllables in Japanese words by native Swedish speakers. The study explores factors such as word type, pitch placement, and sentence structure that influence L1 Swedish speakers' accuracy in identifying the prominent syllable in Japanese words. The study also highlights the influence of linguistic context and individual variation on the perce

Trauma i barndomen har en betydande inverkan på livslång fysisk och mental hälsa samt utveckling. Tidiga interventioner stärker barnets motståndskraft och mildrar traumans långsiktiga effekter på välbefinnandet. En sådan intervention går ut på att utbilda viktiga vuxna i barnets omgivning för att skapa en gynnsam miljö. Traumamedveten omsorg (TMO) är en intervention som erbjuds som ett utbildningsChildhood trauma significantly impacts lifelong physical and mental health and development. Early interventions enhance child resilience and mitigate trauma's long-term effects on wellbeing. One such intervention is educating adults significant in the child’s life to create a nurturing environment. Trauma-informed Care (TIC, in Swedish “Traumamedveten Omsorg”, TMO) is an intervention offered a
