  1. 1. Computational Analysis of Spray Deflector Designs

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Osman Gyokhan Ali; [2023]
    Keywords : Planing Hulls; Spray Deflector; Hull Modification; Computational fluid dynamics CFD ; resistance; trim angle; heave; CD-adapco Star CCM ; Numerical Ventilation; Phase Replacement; Modified HRIC Scheme; Volume Fraction Source Term; Reynolds averaged Navier-Stokes RANS ; Volume of Fluid VOF ; SST K-Omega Turbulence Modelling; Höghastighetshantverk; modelldesign; spraydeflektor;

    Abstract : Planing hull is a common hull design concept which decreases the resistance while speed is increasing for a specific speed range. It is also suitable for hull modifications to achieve higher efficiency. Spray deflector is a promising hull modification which offers extra resistance decreasing and less vertical acceleration for planing hulls. READ MORE

  3. 2. Model Design for Further Spray Deflector investigation

    University essay from KTH/Marina system

    Author : Xinguo Wang; [2021]
    Keywords : High-Speed Craft; Model Design; Spray Deflector; Höghastighetshantverk; modelldesign; spraydeflektor;

    Abstract : Planing hull is one solution to break the speed barrier of conventional hull, but as the boat reaches a high speed, massive whisker spray will be developed and attached to the hull, which causes a notable resistance increase. A Swedish company Peterstep invented an innovative spray deflector that can deflect the spray backwards and harvest kinetic energy from the spray. READ MORE

  4. 3. Validation of theoretical cost model for Power and Reliability : Case study of a reliable Central Direct Memory Access system

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

    Author : Sonal Shrivastava; [2021]
    Keywords : Single event upsets; Extra-functional properties; System on Chip; Mean Time Between Failure; Power consumption; Enstaka händelse störs; Extra funktionella egenskaper; System på chip; Medeltid mellan misslyckande; Energiförbrukning;

    Abstract : Safety-critical applications employed in automotive, avionics and aerospace domains are placed under strict demands for performance, power efficiency and fault tolerance. Development of system hardware and software satisfying all criteria is challenging and time-consuming. READ MORE

  5. 4. Modeling user-to-user growth : Predicting word of mouth in social networks

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Marcus Kohlberg; [2012]
    Keywords : ;

    Abstract : Syftet med uppsatsen var att undersöka vilka faktorer som är viktiga att beakta när man modellerar informationsspridning i ett socialt nätverk. Dessa bestämmande faktorer sätts därefter i relation till några existerande modeller inom området, detta för att få en förståelse för hur faktorerna kan integreras i just en sådan modell. READ MORE
