1. 1. Evaluation of five hardwood species from Zambia to produce fuel pellets for cooking purposes : Study with a single pellet press including pellet production, post production testing and X-ray examinations

   University essay from Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

   Author : Annika Silvennoinen; [2023]
   Keywords : Pelletizing; Pellet Production; Wood Species; X-Ray examinations; Pelletisering; Pelletstillverkning; Träslag; Röntgenundersökningar;

   Abstract : 81% of the population in sub-Saharan Africa relies on charcoal and firewood to cover their energy needs for cooking. In Africa charcoal is usually produced by burning tree in a traditional kilns and then the food is cooked with a carbon-fired stoves indoors. READ MORE

3. 2. Monetary Policy with Credit Market Frictions

   University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

   Author : Mambuna Njie; [2023]
   Keywords : Monetary policy; Investments; Credit frictions; Collateral constraints;

   Abstract : I study the role of collateral as a source of financial friction in the transmission of monetary policy towards firms' investments. First, I use a panel of Swedish firms to estimate the heterogeneity in firm investment responses to monetary policy shocks conditional on collateral. READ MORE

4. 3. Accuracy Improvement and Joint Stiction Relieve in Robot Arms Movement Applying Torque-Based Cartesian Impedance Control With Dithering

   University essay from Lunds universitet/Institutionen för reglerteknik

   Keywords : Technology and Engineering;

   Abstract : Robots are nowadays present and essential in a wide range of applications, and robot arms in particular are capable of performing various tasks such as inspection, material handling, and welding. They can be classified into several types, depending on their structure and purpose. READ MORE

5. 4. Improving the guidance, navigation and control design of the KNATTE platform

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Lars Lundström; [2023]
   Keywords : Multisensor Data Fusion; Nonlinear Kalman Filter; Neural Network;

   Abstract : For complex satellite missions that rely on agile and high-precision manoeuvres, the low-friction aspect of the space environment is a critical component in understanding the attitude control dynamics of the spacecraft. The Kinesthetic Node and Autonomous Table-Top Emulator (KNATTE) is a three-degree-of-freedom frictionless vehicle that serves as the foundation of a multipurpose platform for real-time spacecraft hardware-in-the-loop experiments, and allows emulation of these conditions in two dimensions with the purpose of validating various guidance, navigation, and control algorithms.

6. 5. Forming wide-orbit planets via pebble accretion

   University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Author : Nerea Gurrutxaga; [2023]
   Keywords : Planet Formation; Pebble Accretion; Protoplanetary Disk; Wide-Orbit Planet; Physics and Astronomy;

   Abstract : The possibility that detected substructures in protoplanetary disks, such as gaps, rings and cavities, are created by distant protoplanets has prompted an inquiry into the mechanism responsible for their formation. These wide-orbit young bodies are likely to form relatively rapidly in the outer regions of circumstellar disks. READ MORE
