    University essay from KTH/Matematisk statistik; KTH/Matematisk statistik

    Author : Emil Backman; David Petersson; [2020]
    Keywords : Pension; internal rate of return; applied mathematics; big matrix; numerical methods; large eigenvalue problem; finance; risk analysis; extreme value modeling; probability; stochastic modeling; Pension; intern ränta; tillämpad matematik; stora matrismetoder; numeriska metoder; stora egenvärdesproblem; finans; riskanalys; modellering av extrema värden; sannolikhet; stokastisk modellering;

    Abstract : Pensionsmyndigheten's (the Swedish Pensions Agency) current calculation of the internal rate of return for 7.7 million premium pension savers is both time and resource consuming. READ MORE

  2. 2. Reinforced Concrete Structures Subjected to Imposed Deformations: A Study of Cracking due to Shrinkage in Slab Foundations for Residential Houses

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

    Author : Henrik Johansson; Martin Heinegård; [2020]
    Keywords : Reinforced concrete structures; nonlinear finite element analysis; crack widths; imposed deformations; shrinkage; foundation slabs; fracture mechanics; Atena 2D; Technology and Engineering;

    Abstract : The need for limiting crack widths in reinforced concrete structures is due to durability, tightness towards gaseous and liquid substances, and for aesthetic reasons. Although concrete cracks at relatively low tensile stresses and can not be avoided, strategies for crack control can be adopted to meet the requirements. READ MORE

  3. 3. A comparative study of IEEE 754 32-bit Float and Posit 32-bit floating point format on precision. : Using numerical methods.

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS); KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Johan Besseling; Anders Renström; [2020]
    Keywords : ;

    Abstract : Posit is a new way of representing floating points in computers. This thesis investigates the precision of the 32-bit Posit floating point format compared to the current standard 32-bit IEEE 754 Float format by conducting tests with numerical methods. Posit was chosen due to its promising results in previous work. READ MORE

  4. 4. The Development of a New High Aspect-Ratio Turbulent Channel Flow Facility

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Agastya Parikh; [2020]
    Keywords : ;

    Abstract : Turbulent channel flows are of great interest for investigations of modified wall boundary conditions due to their well-understood characteristics and their broad applicability. In a reversal of typical trends, they can often be more difficult to investigate experimentally than to simulate owing to the far-reaching influence of corner effects as well as the need for development lengths in excess of 200 channel half-heights in order to produce high-quality flow.

  5. 5. Analytical Calibration Scheme Suitable for Modern Mobile Communication Systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ramez Hamarneh; [2020]
    Keywords : ;

    Abstract : Modern systems utilize multiple transceiver modules to enhance capacity by directing the energy of the basestation only at the desired directions using beamforming algorithms. To accurately control the beam patterns, the phase and amplitude at each antenna port must be manipulated to follow the desired beam weight response. READ MORE
