  1. 11. Metal Powder Benchmarking

    University essay from KTH/Materialvetenskap

    Author : Ananthakrishna Sajithkumar; [2021]
    Keywords : Selective laser melting; powder characterisation; flow behaviour; Selektiv lasersmältning; karakterisering av pulver; flödesbeteende;

    Abstract : Metal  additive  manufacturing  technologies  are  widely  employed  in  the aerospace, automotive  and  medical  industries. Selective  laser  melting  is  a type  of  metal additive manufacturing process in which powders are consolidated layer by layer in a predefined pattern with the help of a laser beam to create a component.

  3. 12. Comparative Study of CPU and GPGPU Implementations of the Sievesof Eratosthenes, Sundaram and Atkin

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Jakob Månsson; [2021]
    Keywords : General Purpose Graphics Processing Unit; Parallelization; Prime number; Sieve.;

    Abstract : Background. Prime numbers are integers divisible only on 1 and themselves, and one of the oldest methods of finding them is through a process known as sieving. A prime number sieving algorithm produces every prime number in a span, usually from the number 2 up to a given number n. READ MORE

  4. 13. Integer factorization algorithms

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Joakim Nilsson; [2020]
    Keywords : ;

    Abstract : The mathematical area of integer factorization has gone a long way since the early days of Pierre de Fermat, and with simpler algorithms developed in the last century such as the Trial division and Pollards rho algorithm to the more complex method of the Quadratic sieve algorithm (QS), we have now arrived at the General Number Field Sieve (GNFS) which has been recognized as the fastest integer factorization algorithm for very large numbers. Today the research of integer factorization has many applications, among others in the security systems of encryption methods like the famous RSA algorithm. READ MORE

  5. 14. Evaluation of alternative methods forquality control of Tungsten Carbide : An evaluation of four different particle measuring techniques

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Author : Markus Näsman; [2019]
    Keywords : Particle measurement; Quality control; Tungsten Carbide; Hard metal; Fisher Sub-Sieve Sizer; Brunauer Emmett Teller; X-ray Diffraction; Laser Diffraction;

    Abstract : The purpose of this study was to evaluate four different measuring methods as potentialquality control tests for Tungsten Carbide (WC) raw material used in the hard metalmanufacturing at Seco Tools Fagersta. This was warranted as the current quality testcalled the HcK test, is very time consuming and the results provided that are used formilling time calculations cannot be relied on. READ MORE

  6. 15. Spill vid timotejtröskning : hur mycket spills vid olika körhastigheter?

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Arvid Ivehag; [2018]
    Keywords : Timotej; Gräsfrö; Vallfrö; Gräsfröskörd; Timothy; Skakartröska; Rotortröska;

    Abstract : Målet med detta examensarbete har varit att göra praktiska tester för att ta reda på vad tröskans hastighet har för betydelse för spillet vid timotejtröskning. I Sverige har det inte tidigare gjorts några omfattande försök just på detta. Under sommaren 2017 har försök gjorts på tre gårdar. READ MORE
