1. 1. Channel Estimation and Power Control Algorithms in the Presence of Channel Aging

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

   Author : Yan Bixing; [2023]
   Keywords : Fading channel; auto-regressive model; power allocation; uncrewed aerial vehicle networks; Fading kanal; auto-regressiv modell; krafttilldelning; obemannade flygfordonsnätverk;

   Abstract : Power allocation algorithms that determine how much power should be allocated to pilot and data symbols play an important role in addressing the trade-off between accurate channel estimation and high high spectral efficiency for data symbols in the presence of time-varying fading channels. Dealing with this trade-off is highly non-trivial when the channel changes or ages rapidly in time. READ MORE

3. 2. Using a GIS to enable an economic, land use and energy output comparison between small wind powered turbines and large-scale wind farms: the case of Oslo, Norway.

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Colin Potter; [2023]
   Keywords : Geography; GIS; Wind power; Renewable energy sources; urban wind energy; urban areas; planning; vertical axis wind turbines; comparative studies; urban integrated energy systems; Oslo; Roan; Earth and Environmental Sciences;

   Abstract : Responding to an identified knowledge gap, the study aims to determine if smaller wind turbines located on top of existing urban buildings are more resource efficient (land utilization and economically) than large scale wind farms. To answer this question, using a GIS, the resource efficiency of the Roan wind farm in Northern Norway was compared to a theoretical modeled installation of small-scale wind turbines on top of buildings within a 2km radius study zone in central Oslo.

4. 3. Cost Estimation, Budgeting and OEE Analysis for Binder Jetting at Sandvik Additive Manufacturing Division

   University essay from KTH/Produktionsutveckling

   Author : Ankita Shanawad; [2023]
   Keywords : Binder Jet Additive Manufacturing; Overall Equipment Efficiency; Key Performance Indicator;

   Abstract : The master thesis at Sandvik Additive Manufacturing Division, Sandviken, aims at three things. The first step is to estimate the cost of a Binder jet Additive Manufacturing method and identify the key cost drivers in the manufacturing process, since cost estimation can help the organisation to understand the cost factors that are affecting the product's price.

5. 4. Contribution to the Understanding of the Effects of Propagation through the Ionosphere of P-band SAR Data

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

   Author : Johannes Samuel Erland Rönner; [2023]
   Keywords : Synthetic aperture radar; Ionosphere;

   Abstract : The BIOMASS mission from the European Space Agency (ESA) is designed to measurebiomass and carbon content in Earth’s forests. To account for phase changes caused byionospheric variations, a map-drift autofocus algorithm is developed, which utilises a phasescreen of the ionosphere to eliminate phase errors in the signal.

6. 5. Improvement and Standardization of Forklift Remanufacturing : Action Research on Toyota Material Handling Sweden forklift remanufacturing

   University essay from Linköpings universitet/Produktionsekonomi

   Author : Mattias Dang Vu; Sabah Arouk; [2023]
   Keywords : Remanufacturing; Inspection; Process flow; Cost estimation; Decision-making; Återtillverkning; Inspection; Processflöde; Kostnadsuppskattning; beslutsfattande;

   Abstract : The current production field operates on linear resource flows, characterized by known supply and consistent manufacturing materials. In contrast, a remanufacturing system experiences variable process flows for each produced unit, even though the end product remains the same. READ MORE
