1. 1. Development of a Hydraulic Front Wheel Drive for a Battery Electric Truck

   Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

   Författare :Johan Humla; Samuel Friman; [2023]
   Nyckelord :;

   Sammanfattning : This master thesis work has been executed at Volvo GTT in Gothenburg. Focus has beenlaid on implementing a hydraulic front wheel drive (HFWD) system on a battery electricvehicle (BEV). The earlier concept builds have been performed on internal combustionengine (ICE) driven trucks at Volvo Trucks. LÄS MER

3. 2. An Inexpensive Alpha Spectrometer Based on a p-i-n Photodiode : Making Advanced Particle Detectors From Common Commercial Components

   Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

   Författare :Elias Arnqvist; [2022]
   Nyckelord :Alpha spectroscopy; alpha particle; particle detector; radiation detector; p-i-n diode; PIN diode; photodiode;

   Sammanfattning : The purpose of this project was to design, construct, and evaluate an alpha spectrometer based on an inexpensive p-i-n photodiode as a radiation detector. The BPX-61 p-i-n photodiode was selected and calculated to have a 93 µm wide sensitive volume at 25 V reverse bias. LÄS MER

4. 3. Temperature Compensation in CMOS Ring Oscillator

   Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

   Författare :Xiaohua Wei; Dingyufei Zhang; [2022]
   Nyckelord :Current Starved Ring Oscillator CSRO ; Temperature compensation; Supply voltage compensation; Stable frequency; Digital controlling; Phase Frequency Detector PFD ; Dynamic comparator; Bidirectional counter; Charge pump CP ; Frequency divider; Power consumption; AMS 0.35 um; EDA tool Cadence;

   Sammanfattning : A digital system is often required to operate under a specific frequency. A ring oscillator can be helpful in this circumstance because it can generate a signal with a specific frequency. However, a ring oscillator is also sensitive to the environment temperature. LÄS MER

5. 4. Optimizing Control Algorithm for Indirect Liquid ThermalManagement of Batteries : A Study Executed at Northvolt

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Mantas Petrosius; [2021]
   Nyckelord :;

   Sammanfattning : The vast expansion of intermittent sustainable energy generation has favoured a gradual adoption of lithium-ion batteries in various industrial and automotive applications. Despite its many inherent merits, this storage technology is very vulnerable to temperature variations: the performance and lifespan of LIBs are substantially influenced by their load cycles, thermal behaviours, and operating temperature range.

7. 5. Capillary Organic Electronic Ion Pump for Delivering Malic Acid - Towards Better Understanding of Drought Tolerance in Tropical Plants

   Master-uppsats, Linköpings universitet/Laboratoriet för organisk elektronik; Linköpings universitet/Tekniska fakulteten

   Författare :Alexandra Sandéhn; [2021]
   Nyckelord :malic acid; malate; ion delivery; implantable devices; organic bioelectronics; plants; Teknisk fysik; Teknisk fysik;

   Sammanfattning : Delivery of biologically relevant ions such as drugs, neurotransmitters and hormones have been recognized as powerful a tool to control physiology of animals and plants for research purposes and practical applications. In the plant research community, ions are most commonly delivered as part of a solvent by soaking, spraying, pipetting or by adding to the soil. LÄS MER
