  1. 1. Towards a method for antenna impedance tailoring through shapeoptimization, with a bound on the associated cost-function

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

    Author : Cem Kesici; [2020]
    Keywords : ;

    Abstract : Over the last years, there has been an interest in designing antennas that operateat higher frequencies. In most applications, these antennas work jointly withPower Amplifiers. However, most commercial Power Amplifiers have a nonstandardoptimal load-pull impedance in their optimal operating frequencies. READ MORE

  2. 2. Evaluation of Peridynamics and Its Application in Harmonic-Structured Material Simulations

    University essay from Lunds universitet/Mekanik

    Author : Theodor de Sousa; [2020]
    Keywords : peridynamics; peridigm; harmonic-structured materials; computational mechanics; fracture modelling; Technology and Engineering;

    Abstract : Materials are constantly sought to be improved in different manners. Two of the most common characteristics to improve are strength, and ductility. Historically, materials are modified homogeneously to achieve improvement, while the past century has also seen composite materials becoming standard-issue within various industries. READ MORE

  3. 3. Estimating Weight of Pressed Carbide Inserts using Machine Learning

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

    Author : Adrian Lökk; [2020]
    Keywords : ;

    Abstract : In any mass-scale production pipeline, even the slightest efficiency improvement can have massive beneficial implications in terms of cost and time. Therefore, at Sandvik Coromant there is a drive to innovate and implement new technologies that can be integrated into their carbide insert production line. READ MORE

  4. 4. Chemical Interactions between tool and Aluminium alloys in metal cutting

    University essay from KTH/Materialvetenskap

    Abstract : Aluminium applications in automotive will increase by 25 % over the next decade, mainly driven by the electrification and the reduction of fuel consumption. This diploma work aims to increase the understanding of the chemical interactions between aluminium alloys and typical tool systems in metal cutting. READ MORE

  5. 5. Falsk såbädd med Väderstad CrossCutter Disc : en jämförelse med standardtallrikar och gåsfotsskär

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Sara Hellgren; [2019]
    Keywords : CrossCutter Disc; falsk såbädd; fröbank; groning; groningsvila; gåsfots-skär; Lapsana communis; ogräsbekämpning; ; reducerad bearbetning; spillsäd; tallriks-redskap; Tripleurospermum perforatum; Veronica agrestis;

    Abstract : Reducerad jordbearbetning har ökat i popularitet bland svenska lantbru-kare under senare år, främst på grund av tidsbrist och minskad lönsamhet i jordbruket. En mindre intensiv jordbearbetning har också en rad andra posi-tiva effekter, framförallt för markstrukturen och att växtnäringsläckaget minskar, men en vanlig konsekvens av reducerad jordbearbetning är att ogräsförekomsten ökar, vilket gör växtodlingen beroende av herbicider.
