1. 1. Developing a Neural Network Model for Semantic Segmentation

   M1-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Ronny Westphal; [2023]
   Nyckelord :Semantic segmentation; neural network; Unity Barracuda; PyTorch; augmented reality; Semantisk segmentering; neurala nätverk; Unity Barracuda; PyTorch; augmenterad verklighet;

   Sammanfattning : This study details the development of a neural network model designed for real-time semantic segmentation, specifically to distinguish sky pixels from other elements within an image. The model is incorporated into a feature for an Augmented Reality application in Unity, leveraging Unity Barracuda—a versatile neural network inference library. LÄS MER

3. 2. Managing supply risks post pandemic : Understanding gaps in organizational decision-making and proposing a tool to manage differences

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Aron Joshi; [2023]
   Nyckelord :manufacturing; supply chain risk management; performance; decision-making; trade-offs; Tillverkning; riskhantering av försörjningskedjor; förmåga; beslutsfattande; avvägning;

   Sammanfattning : Effective supply chain risk management has become crucial for companies as supply chains have become more complex and integrated due to decades of globalization. The outbreak of the Covid-19 pandemic has highlighted the fragility of global supply chains and the necessity of manufacturing companies to have a robust supply chain in order to be resilient towards supply chain disruptions.

4. 3. Investigation of MIDEL 7131’s Dielectric Breakdown Strength and Thermal Behaviour : Master Thesis, an experimental study using concentric-like electrodes at elevated temperatures to study breakdowns

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Kim Lin; [2023]
   Nyckelord :Dielectric strength; High voltage; Liquid dielectric; MIDEL 7131; Electrical breakdown; Temperature cycle; Dielektrisk styrka; Högspänning; Dielektriska vätskor; MIDEL 7131; Elektrisk nedbrytning; Temperaturcykling;

   Sammanfattning : Dielectric insulation are constantly exposed to various stresses, while also being expected to last for long periods of time. Naturally, they degrade with use and in demanding operational environments, this degradation phenomena can be accelerated, leading to costly consequences. LÄS MER

5. 4. When is Electric Freight Cost Competitive? : Computational modeling and simulation of total cost of ownership for electric truck fleets

   Uppsats för yrkesexamina på avancerad nivå, Linköpings universitet/Institutionen för ekonomisk och industriell utveckling

   Författare :Anton Zackrisson; [2023]
   Nyckelord :electric freight; battery-electric trucks; total cost of ownership; decision making under deep uncertainty DMDU ; cost-competitiveness; exploratory modeling and analysis EMA ; EMA workbench; quasi-Monte Carlo method; VRP; EVRP; elektrifiering; godstransport; elektriska lastbilar; total ägandekostnad; kostnadskonkurrenskraft; ruttoptimering;

   Sammanfattning : Battery electric trucks (BETs) offer environmental benefits in terms of reduced carbon emissions and enhanced energy efficiency but have been challenged with economic viability compared to conventional internal combustion engine trucks (ICETs) caused by substantial acquisition costs, limited charging infrastructure, and concerns regarding range and payload capacity.  Previous studies focus on TCO at the vehicle or policy level but overlook the system and firm-level impacts.

7. 5. Prediction of Short-term Default Probability of Credit Card Invoices Using Behavioural Data

   Master-uppsats, KTH/Matematisk statistik

   Författare :Billy Lu; [2022]
   Nyckelord :Probability of Default; Credit Risk; Short-term Default Prediction; Machine Learning; Gradient Boosting; Thresholding; Sannolikheten för Fallissemang; Kreditrisk; Kortsiktig Fallissemang Prediktion; Maskininlärning; Gradientförstärkning; Tröskling;

   Sammanfattning : Probability of Default (PD) is a standard metric to model and monitor credit risk, a major risk facing financial institutions. Traditional PD models are used to forecast risk levels in the long-term, while short-term PD predictions are rarer, but they can support management decisions on an operational level. LÄS MER
