  1. 1. Coordination of base station energy storage for renewable energy grid : Utilizing Base Station battery storage to stabilize grids with Variable Renewable Energy Sources

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

    Author : Linus Pekkanen; [2022]
    Keywords : Renewable Energy; Energy Storage; Optimal Control; Model Predictive Control; Smart Grids; Machine Learning; Neural Networks; Base Stations; Telecommunications; Förnybar Energi; Energilagring; Optimal Kontroll; Modellprediktiv Reglering; Smarta Elnät; Maskininlärning; Neurala Nätverk; Basstationer; Telekommunikation;

    Abstract : An increasing amount of variable renewable energy sources are being added to the world’s power grids both as an effort to reduce greenhouse gas emissions in the fight against climate change but also because some of the energy sources with the lowest levelized cost of energy are variable renewable energy sources such as wind and photovoltaics. These energy sources come with inherent difficulties since their energy production is neither constant nor entirely controllable and can cause issues for the power grids if they cause power production and consumption to become imbalanced.

  2. 2. A hashing algorithm based on a one-way function in the symmetric group Sn

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Adrian Perez Keilty; [2022]
    Keywords : cryptography; hashing; symmetric group; one way function;

    Abstract : We have found an operation between permutations in the symmetric group Sn upon which we have experimentally derived results that can be linked to desirable properties in cryptography, mainly in the domain of one-way functions. From it, we have implemented a beta version of an algorithm for a hashing function by exploiting the operation’s low computational cost for speed and its properties for security. READ MORE

  3. 3. Energy optimization of Byggebo's properties

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Frida Lantz Bergqvist; Moa Ahlstrand; [2022]
    Keywords : ;

    Abstract : I världen pågår klimatförändringar. Växthuseffekterna ökar, den globala uppvärmningen blir större och jordens livsmiljö förändras snabbt. För att stoppa vad de förödande konsekvenserna innebär krävs det en förändring. READ MORE

  4. 4. Importance Sampling in Wireless Communication Systems with Ultra-Low Error Rates

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Bharat Maheshwari; Yewen Zhou; [2022]
    Keywords : error region; Monte Carlo; importance sampling; rejection sampling; Kullback-Leibler divergence.; Technology and Engineering;

    Abstract : Simulation mimics the behaviour of real world processes or the system over time. It helps us to understand the impact of modification and the effect of introducing various interventions to a system. READ MORE

  5. 5. The derivation of first- and second-order backpropagation methods for fully-connected and convolutional neural networks

    University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematikcentrum

    Author : Simon Sjögren; [2021]
    Keywords : Mathematics and Statistics;

    Abstract : We introduce rigorous theory for deriving first and second order backpropagation methods for Deep Neural Networks (DNN) whilst satisfying existing theory in DNN optimization. We begin by formally defining a neural network with its respective components and state the first and second order chain rule with respect to its partial derivatives. READ MORE
