  1. 1. Braids and configuration spaces

    University essay from Uppsala universitet/Geometri och fysik

    Author : Andersson Rasmus; [2023]
    Keywords : braids; braid groups; configuration space; algebraic topology; group theory; fundamental group; covering spaces;

    Abstract : A configuration space is a space whose points represent the possible states of a given physical system. As such they appear naturally both in theoretical physics and technical applications. READ MORE

  3. 2. Evaluate Machine Learning Model to Better Understand Cutting in Wood

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Md Tahseen Anam; [2021]
    Keywords : Machine Learning; Mask R-CNN; Image Analysis; Wood Image; Pith Detection; Knots; Cracks; Cutting Efficiency;

    Abstract : Wood cutting properties for the chains of chainsaw is measured in the lab by analyzing the force, torque, consumed power and other aspects of the chain as it cuts through the wood log. One of the essential properties of the chains is the cutting efficiency which is the measured cutting surface per the power used for cutting per the time unit. READ MORE

  4. 3. Bekämpning av rotgallnematodarterna Meloidogyne hapla, M. chitwoodi och M. fallax : grödors naturliga resistens som alternativ till svartträda?

    University essay from SLU/Dept. of Ecology

    Author : Jesper Fritzson; [2020]
    Keywords : rotgallnematoder; naturlig resistens; fånggröda; bekämpning; oljerättika; tagetes;

    Abstract : Växtparasitära nematoder börjar bli ett allt större problem världen över där de orsakar stora ekonomiska skador. Bekämpningen av dessa blir svårare allt eftersom kemiska bekämpningsmedel mot nematoder mer och mer globalt förbjuds på grund av dess toxiska påverkan på bland annat applicerande lantbrukare samt ekosystem runtom och i nematodinfekterade fält.

  5. 4. Suturing in Surgical Simulations

    University essay from KTH/Numerisk analys, NA

    Author : Kiran Beersing-Vasquez; [2019]
    Keywords : Surgical suturing; spline model; Lagrange constraints; multibody dynamics; differential algebraic equations; Kirurgisk suturering; spline-modell; Lagrange-begränsningar; multikroppsdynamik; differentiella algebraiska ekvationer;

    Abstract : The goal of this project is to develop virtual surgical simulation software in order to simulate the suturing and knot tying processes associated with surgical thread. State equations are formulated using Lagrangian mechanics, which is useful for the conservation of energy. READ MORE
