1. 11. A Contemporary Six Sigma and Lean Integration : Towards the Ideal State

   University essay from Linköpings universitet/Logistik- och kvalitetsutveckling

   Author : Jonn Wenchert; [2017]
   Keywords : Statistical Process Control; Lean Production; Six Sigma; Lean Six Sigma; Six Sigma Lean; Information System Development; Information System Research; Modern Factory;

   Abstract : A new reality, where human labor is replaced by automated machines is causing production management to rethink how they can steer the production to meet their customers demand. There is a gap of values, techniques and tools to communicate with the processes existing in the new modern factories, where data sometimes is the single output. READ MORE

3. 12. A comparative study on twostandardised electrochemicalmethods with emphasis the effectof microstructure and inclusionson pitting corrosion on duplexstainless steel

   University essay from KTH/Materialvetenskap

   Author : Khadijeh Jafari; [2016]
   Keywords : Duplex stainless steel; pitting corrosion; electrochemical test; potentiostatic; potentiodynamic ASTM; inclusion; microstructure; sigma phase; phase arrangement;

   Abstract : Duplex stainless steel (DSS) that developed in the 1930’s is a type of steel that consists of bothaustenite and ferrite phases in an almost equal proportion. It inherits properties of both ferriticand austenitic stainless steel and so it has good mechanical and corrosion resistance propertiesthat makes it suitable material in different industries with aggressive environment.

4. 13. Using Six Sigma Methodology to improve the performance of the Shipment Test

   University essay from KTH/Radio Systems Laboratory (RS Lab)

   Author : Yang Bin; [2015]
   Keywords : Six Sigma; quality; performance; AXE; Six Sigma; kvalitet; Prestanda; AXE;

   Abstract : Competition and lead-time pressure motivates us to find new and better ways of continuously improving the output of our work. The emphasis on improvement in both efficiency and quality has become more and more significant in daily activities. READ MORE

5. 14. Interferometer Design for Attosecond Experiments

   University essay from Lunds universitet/Fysiska institutionen

   Author : Simon Ek; [2015]
   Keywords : FRED; attophysics; atomic physics; stability; simulations; MATLAB; interferometer design; interferometers; error propagation; Physics and Astronomy;

   Abstract : Resolving fast events, such as electron dynamics, requires short light pulses. To this date the shortest available light pulses are created using High-order Harmonic Generation (HHG) and have a duration of a few hundred attoseconds (1 as = $10^{-18}$ s). READ MORE

6. 15. The Process Influence on Strength Properties of an Austenitic Stainless Steel (254 SMO)

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Anna Hellqvist; [2014]
   Keywords : stainless steel; hot rolling; levelling; strength; material properties; process parameters;

   Abstract : This work has been performed at Outokumpu Stainless AB, QPE, in Degerfors where focus is on production of hot rolled tailor-made quarto plate in special stainless steel grades such as highly alloyed austenitics and duplex steel grades. After a period with low values in strength and a lot of deviations in tensile tests for the highly alloyed austenitic stainless steel, 254 SMO, there was a need to investigate what influence some parameters during process has on strength values.
