  1. 1. Spectral broadening of 4 mJ femtosecond pulses using a bulk multi-pass cell

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Saga Westerberg; [2023]
    Nyckelord :Lasers; Ultrashort; Nonlinear Optics; femtosecond; Multi-Pass Cell; Spectral broadening; pulse post-compression; Self phase modulation; Physics and Astronomy;

    Sammanfattning : Nonlinear optical effects can be used for spectral broadening, which the basis of the field of post-compression of laser pulses. When the intensity of light becomes high enough the refractive index becomes intensity dependent, and as the intensity often varies both with position and time so does the refractive index. LÄS MER

  3. 2. Modeling of RF Heating in the JET Tokamak

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Emil Söderman; Wilhelm Holmberg; [2021]
    Nyckelord :fusion; tokamak; ICRH; RF heating; JET;

    Sammanfattning : Fusion reactors need methods to couple externalpower to confined plasmas. Ion cyclotron resonance heating(ICRH) is a method to radiate electromagnetic waves to couplepower to the kinetic motion of gyrating ions in a plasma. In thisreport we study ICRH with regard to the dispersive effects ofthe confined plasma in the JET tokamak. LÄS MER

  4. 3. Konsten att stå på egna ben : - En materialistisk kontextanalys av hur konst och konstnärskap föreslås finansieras på den kommersiella marknaden enligt tidskriften Artworks: the arts and business journal 

    Kandidat-uppsats, Södertörns högskola/Konstvetenskap

    Författare :Paulina Immonen; [2020]
    Nyckelord :new economy; value; speculation; Marina Vishmidt; art; business; creativity; kulturekonomi; konstens autonomi; ekonomisering; spekulation; konstproduktion; kreativitet; konstplattform; kreativ sektor; senkapitalism; modernitet; ny ekonomi; Artworks; mänskligt kapital; värde;

    Sammanfattning : This essay examines the content in the Artworks: the arts & business journal with the aim to find out what economic models and business ideas are presented to be applied by the artists and the artworld. The method being used is a material context analysis, together with Marxist capitalist theories, with ‘speculation as a mode of production’ according to Marina Vishmidt, as a philosophical analysis tool.

  5. 4. When can superfast fashion be green?

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Nike Grapengiesser; [2020]
    Nyckelord :Sustainability; Biodegradable; Textile Value Chain; Distributed Production; 3D Printer; Biogas; Zero-Waste; Earth and Environmental Sciences;

    Sammanfattning : Although that the textile-industry is considered the world’s second most climate affecting industry, consumption seems to never cease. The Swedish start-up project Streamateria provides new opportunities through a distributed production-line that offers bio-degradable garments through 3D-printing technology, with the ambition to meet consumer demand for "fast fashion" The aim of the study is to identify the environmental implications and potential benefits as well as disclaimers related to Streamaterias offering.

    Nyckelord :Hyperloop; Hyperloop in Sweden; Transportation; Infrastructure; Transport Market Dynamics; The Swedish Transport Market; New Mode of Transportation; Emerging Technologies; Disruptive Innovation; Diffusion of Innovation; Characteristics of Diffusion; Technical Transition; Socio-technical Transition; Transformational Pressure; Window of Opportunity; Multi-Level Perspective MLP ; Technology Readiness Level TRL ; Hyperloop; Hyperloop i Sverige; Transport; Infrastruktur; Transportmarknadens Dynamik; Den Svenska Transportmarknaden; Nya Transportsätt; Framväxande Teknik; Disruptiv Innovation; Diffusion av Innovation; Egenskaper för Spridning av Innovation; Teknisk övergångsteori; Socio-teknisk övergångsteori; Transformationstryck; Möjlighetsfönster; Perspektiv i Multipla Nivåer MLP ; Teknisk Mogenhetsnivå TRL ;

    Sammanfattning : Transportations role in society is increasingly important and today it has a prominent role in business, citizens lives as well as in the world economy. The increasing globalization and urbanization puts significant pressure on the existing transport system, with increasing demand for high-speed travel. LÄS MER
