1. 1. Energy-Efficient Fixed-Coefficient FIR Filters for Millimeter-Wave Radios

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Erik Lundell; Gustav Molin; [2023]
   Keywords : Technology and Engineering;

   Abstract : With the introduction of millimeter-wave antenna arrays in 5G base-stations and ever-increasing data volumes, the power consumption of the signal processing in digital radio systems has increased over the last decade. This, combined with increased cost and environmental awareness, has put focus on power optimization. READ MORE

3. 2. Integration of an industrial heat pump for a TES-based power-to-heat system : A techno-economic assessment

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

   Author : Cristian Contreras Aramayo; [2023]
   Keywords : Heat; electricity; industrial heat pump; power-to-heat;

   Abstract : This work aims to investigate the potential electricity savings, as well as the potential decrease in LCoH and OPEX, that an integration of an industrial heat pump can have on a molten salt-based power-to-heat system with integrated thermal energy storage. The original system uses an electric heater to heat up molten salt, which acts as the heat transfer fluid of the system, from which heated steam can be produced and delivered at the output.

4. 3. An Optimization Model for Electric Vehicle Routing with Tractor Swapping

   University essay from KTH/Matematik (Avd.)

   Author : Alexander Strid; Daniel Liu; [2022]
   Keywords : Vehicle Routing Problem VRP ; tractor swapping; electric VRP; rich VRP; heavy goods vehicles; mixed-integer linear programming MILP ; applied mathematics; ruttoptimering; traktorbyte; elektriska lastbilar; tunga lastbilar; linjär heltalsoptimering; tillämpad matematik;

   Abstract : The purpose of this thesis is to investigate how tractor swapping can be implemented in Vehicle Routing Problems (VRP) with electric heavy goods vehicles, and to evaluate how a model that allows for tractor swapping performs, in terms of schedule cost, against a model that does not. Hence, this thesis introduces a new rich VRP variant which includes tractor swapping, as well as time windows, pickup and delivery, and electric vehicles. READ MORE

5. 4. Optimal Time-Varying Cash Allocation

   University essay from KTH/Matematisk statistik

   Author : David Olanders; [2020]
   Keywords : Statistics; Applied Mathematics; Optimization; Cash Allocation; Network Theory; Mixed Integer Linear Program; Transaction Costs; Branch-and-Cut; Statistik; tillämpad matematik; optimering; kapitalallokering; nätverksteori; Mixed Integer Linear Program; transaktionskostnader; Branch-and-Cut;

   Abstract : A payment is the most fundamental aspect of a trade that involves funds. In recent years, the development of new payment services has accelerated significantly as the world has moved further into the digital era. This transition has led to an increased demand of digital payment solutions that can handle trades across the world. READ MORE
