  1. 1. 3D Knit fabrics : optimizing spacer knit fabrics for comfort and breathability in infant products

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Julia Svensson; Hanna Halldorf; [2023]
    Keywords : Spacer fabric; knitting; warp knit; circular knit; textile testing; ProCad Warpknit; infant product; comfort; mechanical properties.;

    Abstract : In this study we looked into an existing textile baby stroller seat and investigated whether there can be any advantage in changing the material to a spacer fabric from perspectives such as functionality, comfort, and sustainability. The subject of 3D knitting, and advanced knitting is being researched more and more because of its versatility in producing and changing parameters of knitted high quality products, but there is a lack of studies done on comfort for children when it comes to knitted spacer fabrics and not many studies have been done on spacer fabrics used for baby seats in strollers or other types of seats for children.

  3. 2. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Sigge Axelsson; Jonas Gartner; Axel Stafström; [2023]
    Keywords : high-voltage; low-current; low-power; DC DC; DC-DC; high-gain; converter; electrohydrodynamic pump; EHD; transformerless converter; Royer-based converter; resonant Royer oscillator; Cockroft-Walton voltage multiplier; CWVM; voltage multiplier; series-connected positive-negative voltage multiplier; SPNVM; planar air-core transformer; planar transformer; high-freqency Royer-based converter; overcurrent protection; LT8331; gallium nitride; GaN; planar PCB-integrated transformers;

    Abstract : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. READ MORE

  4. 3. Skyddsvallar mot översvämning runt Kristianstad : fyller de sin primära funktion och finns även potentiella sekundära funktioner?

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Erika Persson Bivall; [2023]
    Keywords : Klimatförändring; klimatanpassning; översvämningsskydd; sekundära funktioner;

    Abstract : Klimatförändringar är ett allvarligt problem som vi behöver ta ansvar för. När temperaturen ökar i luften ökar även temperaturen i havet vilket orsakar att vattnet expanderar, isarna smälter och vi får kraftigare skyfall. READ MORE

  5. 4. Combining proprietary real-time Ethernet protocols with Time-Sensitive Networking for avionics : A simulation study in OMNeT++ with INET 4.4

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

    Author : Fredrik Ekstedt Karpers; [2023]
    Keywords : Ethernet; Time-sensitivenetworking; Real-timenetworks; IEEE802.1Q; Aeronautics; OMNeT ; Ethernet; Time-sensitive networking; Realtidsnätverk; IEEE 802.1Q; Aeronautik; OMNeT ;

    Abstract : Robust real-time communication is crucial in many safety-critical systems, such as air-crafts. One example of real-time communication within an aircraft is the Ethernet-based protocol called Proprietary Real-Time Ethernet (PRTE), used for sensor data and other hard real-time information exchange.

  6. 5. Automated Solar Panel Shield : An IoT Approach

    University essay from Blekinge Tekniska Högskola

    Author : Raghu Vamsi Sai Rangannagari; Sri Phani Deverakonda; [2022]
    Keywords : Arduino Uno; Weather monitoring; Sensors; Solar panel; Shield;

    Abstract : Context: Solar panels are exposed to different weather conditions and get damaged. Sand storms and hail storms could cause serious damage. However, they need to be used for human survival in almost every harsh condition possible. Objectives: Our goal is to design and create a working prototype of an automated solar panel shield.
