  1. 1. BCP Lithography Defined Arrays of InAs NWs Grown Using MOVPE with Au Seeds

    Master-uppsats, Lunds universitet/Lunds Tekniska Högskola; Lunds universitet/Fasta tillståndets fysik

    Författare :Björn Landeke-Wilsmark; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In this report we outline a detailed process flow for a quick and inexpensive implementation of large dense arrays of InAs nanowires (NWs) grown in the reactive ion etching/etched (RIE) pores of a SiO2/SiNx mask on top of an InAs/Si(111) substrate. The self-assembled (hexagonally close-packed) pattern of poly(methyl-methacrylate) (PMMA) cylinders in a poly(styrene) (PS) matrix adopted by a linear diblock poly(styrene-block-methyl-methacrylate) P(S-b-MMA) block-copolymer (BCP) was transferred to the dielectric stack (consisting of a ≈10 nm plasma enhanced chemical vapour deposition/deposited (PECVD) SiNX layer topped by a thin atomic layer deposition/deposited (ALD) SiO2 film) using a two-step RIE procedure.

  3. 2. Investigating and Modeling Uplink Processing in 5G NR Multisector Scheduler Simulator

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Oskar Nygren; Axel Sneitz-Björkman; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : As the latest generation of wireless access technology called Fifth Generation (5G) New Radio (NR) evolves, computational efficiency is key to keep low cost and flexible deployments for vendors. Understanding how the Digital Signal Processing (DSP) load behaves in the digital units is one aspect to enable this efficiency. LÄS MER

  4. 3. Block copolymer-based hybrid nanomaterials for nanoimprint applications

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska Högskola

    Författare :Philip Sellin; [2022]
    Nyckelord :Block copolymer; Sequential infiltration synthesis; Nanoimprint lithography; Reactive ion etching; Self-assembly; Thermal annealing; Solvent vapour annealing; Nanoprocessing; Nanofabrication; Antibacterial; Technology and Engineering;

    Sammanfattning : In this Master’s thesis project, a block copolymer (BCP) film was used in combination with sequential infiltration synthesis and etching to manufacture a nanoimprint lithography stamp consisting of silicon. The BCP film was designed to contain perpendicularly aligned hexagonally placed cylinders, a pattern that will later be investigated for antibacterial properties after being transferred via nanoimprint lithography to a polymer film.

    Nyckelord :Composite Garment Weaving; Weaving; Pattern Making; Tapestry; Making; Clothes; Fashion; Haute Couture; Design; Loom; Textile; Craft; Block Pattern; Geometry; Fully Fashioned; Zero Waste; Slow Fashion; Sustainability; Sensuality;

    Sammanfattning : In this work, a hand-woven fashion collection is designed. The aim is to create clothes that connect us with life and nature and make us feel that we are part of a vibrant surrounding. LÄS MER

  7. 5. Etablering av strategier och rutiner för seriestorlekar : En fallstudie på Företag X

    Magister-uppsats, Linnéuniversitetet/Institutionen för ekonomistyrning och logistik (ELO)

    Författare :Karl Vinberg; Lukas Klevtun; [2021]
    Nyckelord :Demand patterns; EBQ formula; EOQ formula; Injection molding; Gantt chart; Capacity limitation; Newsvendor formula; Power of Two; Single- stage production system.; Efterfrågemönster; EBQ-modellen; EOQ-modellen; Formsprutning; Gantt-Schema; Kapacitetsbegränsning; Newsvendor; Power of Two; Single-stage production system.;

    Sammanfattning : Purpose: The purpose of the study is to identify, design and apply a method for operational production planning. The purpose of the method is that it takes into account the respective demand patterns of the articles, which determines the choice of calculation model and that the method also takes into account the production capacity limitation set.
