1. 11. The influence of dissolution medium on in vitro dissolution profiles for pulmonary drug delivery

   University essay from Uppsala universitet/Institutionen för farmaceutisk biovetenskap

   Author : Venus Zafranian; [2021]
   Keywords : Inhalation; in vitro dissolution; budesonide; fluticasone propionate; modified andersen cascade impactor; pulmonary drug delivery; dissolution profiles; dissolution medium;

   Abstract : Today, orally inhaled drugs found on the market suffer from variable and discontinuous pulmonary drug release which lowers efficacy and patience compliance. This is usually a consequence of the poor understanding of the interaction and dissolution behavior of drug particles in the lung environment. READ MORE

3. 12. 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

4. 13. Development of a method for estimation of contact fatigue life in hypoid gears

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Srigiripura Sahana Vittal; [2020]
   Keywords : Hypoid Gear; Rolling Contact fatigue; Fatigue life; FEM; Gear Contact life; Spalling; physical testing; fatigue analysis; Hypoidväxel; rullande kontaktutmattning; utmattningslivslängd; FEM; växelkontaktlivslängd; spalling; fysisk testning; utmattningsanalys;

   Abstract : Hypoid gears have been used extensively in automobiles, aerospace, marine and other applications for decades. The special advantages of hypoid gears come with inherent contact complexities of varying curvature and sliding in both profile and lengthwise direction. READ MORE

5. 14. 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.

6. 15. Characterization of property variations in paperboard samples

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Sofia Wretstam; [2018]
   Keywords : Paperboard; variability; property; tensile strength; surface roughness; thickness; distribution.;

   Abstract : In today’s paper and board production, quality control is made on a single cross direction (CD)sample from each tambour. As several different properties are analysed, only a limited number of measurement results are obtained for one property. READ MORE
