1. 6. Reliability Assessment of Electro-mechanical Linear Actuator

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Raveena Dnyaneshwar Adsul; [2021]
   Keywords : Reliability assessment; FMEA; Sensitivity analysis; Tests; Tillförlitlighetsbedömning; FMEA; Känslighetsanalys; Tester;

   Abstract : Syftet med denna avhandling var att uppskatta livslängden och tillförlitligheten för det elektromekaniska linjära ställdonet genom att använda metoder för sannolikhet och statistik, med fokus på att fastställa svagare områden som kan förbättras för att inkludera dessa förbättringar i kommande generation. Bedömningen gjordes kvantitativt och kvalitativt. READ MORE

3. 7. Transition Matrices Conditional on Macroeconomic Cycles: A Portfolio Stress-Test Application

   University essay from Göteborgs universitet/Graduate School

   Author : Jesper Karlsson; [2018-07-04]
   Keywords : Risk Management; Migration Analysis; Intensity Models; IFRS 9; Basel Accords; Portfolio Stress Test;

   Abstract : Transition matrices show the probabilities of credit rating migrations for a pool of ratings within a particular industry, geographical area, time-horizon, etc. Regulation, in the form of Basel accords, has opted for standards in banking that among other techniques use transition matrices, and thus the probability of default, for internally-based risk-assessment, as well as incorporating the external credit rating in the capital requirement calculation.
