This thesis presents methods for estimation and autonomous control of a hexacopter which is an unmanned aerial vehicle with six rotors. The hexacopter used is a ArduCopter 3DR Hexa B and the work follows a model-based approach using Matlab Simulink, running the model on a PandaBoard ES after automatic code generation. The main challenge will be to investigate how data from an Internal Measurement
Popular Abstract in Swedish Avhandlingen behandlar reglering av Homogeneous Charge Compression Ignition (HCCI) motor dynamik. HCCI erbjuder möjligheten att kombinera hög effektivitet med väldigt låga emissioner. Återkopplad reglering är ett sätt att uppnå dessa mål. Avhandlingen diskuterar sensorer, återkopplingsvariabler och aktuatorer för sluten-loop reglering av HCCI förbränningen. Det är demoThe topic of the thesis is control of Homogeneous Charge Compression Ignition (HCCI) engine dynamics. HCCI offers a potential to combine high efficiency with very low emissions. In order to fulfill the potential benefits, closed-loop control is needed. The thesis discusses sensors, feedback signals and actuators for closed-loop control of the HCCI combustion. Closed-loop control of the HCCI combu
The Homogeneous charge compression ignition (HCCI) principle holds promise to increase efficiency and to reduce emissions from internal combustion engines. As HCCI combustion lacks direct ignition timing control and auto-ignition depends on the operating condition, control of auto-ignition is necessary. Since auto-ignition of a homogeneous mixture is very sensitive to operating conditions, a fast
This paper critically examines Rwanda’s Gender Strategy for the Mining Sector through the lenses of Bacchi’s What is the Problem Represented to be (WPR) approach and feminist political ecology (FPE) concepts. Against the backdrop of Rwanda’s post-genocide development journey, the study investigates how gender (in)equality is problematised, (re)presented, and promoted within the context of res
Purpose: The objective of this study is to explore sojourners’ acculturation process within the context of retail spaces and gain a deeper understanding of market-mediated spaces in consumer acculturation. Methodology: The study employed a qualitative research approach. In total, 15 semi-structured interviews with sojourners from eight Asian countries were conducted. The analysis of the data was g
In the field of development studies, few concepts have gained as much prominence as the Participatory Development (PD) approach, which emphasizes on putting the poor and marginalized groups at the heart of development policy planning practices. Central to the PD approach is bottom-up management of development policymaking and practices, which considers learning, empowerment and local ownership as
mRNA-based therapeutics are predicted to have a bright future. Recently, a B2C study was published highlighting the critical bottlenecks of mRNA manufacturing. The study focused on supply bottlenecks of various chemicals as well as shortages of skilled personnel. The assessment of existing messenger ribonucleic acid (mRNA) vaccine processing shows the need for continuous manufacturing processes th
