1. 1. Påverkan av utloppsrörets längd i en automatiskt självtömmande hävert och komponenternas påverkan på tömningshastigheten

   Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad mekanik

   Författare :Nils Attemalm; [2023]
   Nyckelord :;

   Sammanfattning : To facilitates tasks in modern healthcare, innovative solutions can be used and the product Sippi is an example of this. Sippi is a self-emptying siphon device used for monitoring a patient ́s urine production. This report examines one of the two main components of Sippi, known as the disposable unit. LÄS MER

3. 2. En jämförelse mellan platta på mark i betong och Koljerngrund : Utifrån aspekterna klimatpåverkan, kostnad och tid

   Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad mekanik

   Författare :Marika Larsson; Agnes Sandström; [2023]
   Nyckelord :betong; cellglas; förskola; koljerngrund; kostnad; låghus; stål; platta på mark; tid;

   Sammanfattning : The purpose of this study is to compare a concrete slab on ground with a Koljernfoundation based on the given aspects of climate impact, cost, and time. The goal of the study is to identify obstacles and opportunities for the construction industry to use alternatives to concrete slab in new construction of low-rise buildings. LÄS MER

4. 3. Size effect in wood : Characterization of mechanical properties using digital image correlation method

   Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad mekanik

   Författare :Amir Saeidi; Olafur Johannsson; [2023]
   Nyckelord :compression test longitudinal direction; digital image corre- lation DIC ; ncorr; phyton; pinewood; size effect; stiffness matrix; wood- construction; YAWCAM; young’s modulus; digital image correlation DIC ; elasticitetsmodul; furu; kom- pressionstest längs fiberriktning; ncorr; phyton; storlekseffekt; styvhetsma- tris; trä-konstruktion; YAWCAM;

   Sammanfattning : As a natural composite material, wood exhibits complex structural char-acteristics and diverse behavior under compression and tensile forces. Itsanisotropic nature results in mechanical properties that vary depending onthe load direction along its longitudinal, tangential, and radial grains. LÄS MER

5. 4. Investigation of charge injection at electrode-dielectric interface relevant for HVDC cables : Simulation of charge injection and transport dynamics in electrical insulation for HVDC cables

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanik

   Författare :Mohammed Mosa; [2023]
   Nyckelord :BCT model; charge injection; space charge density; electric field distribution; Fowler-Nordheim; Richardson-Schottky;

   Sammanfattning : A bipolar charge transport (BCT) model is used to simulate charge injection and transportdynamics inside insulation material which are used in a high voltage direct current (HVDC)cable. Gaining knowledge about space charge density and electric field distribution in theinsulation material enables minimising charge injection at the metal-insulator interface andavoiding unnecessary energy loss.

7. 5. Wet Spinning of Cellulose-Lignin Precursor for Carbon Fibers : Effect of Coagulation Bath Composition & Spin Finish

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanik

   Författare :Julia Sundmark; [2023]
   Nyckelord :Carbon fiber; Cold alkali; Cold NaOH; lignin; cellulose; wet spinning; Kolfiber; kallalkali; lignin; cellulosa; våtspinning;

   Sammanfattning : Carbon fibers (CF) are a material with a composition of over 90% carbon, which has high mechanical properties and low density. This unique combination of properties makes it requirable in applications such as vehicles, aerospace, wind power, and space industries. Commercially made CF are made using the fossil raw material polyacrylonitrile (PAN). LÄS MER
