  1. 1. Access Point Selection and Clustering Methods with Minimal Switching for Green Cell-Free Massive MIMO Networks

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

    Author : Qinglong He; [2022]
    Keywords : Cell-free massive MIMO; multi-objective optimization; deep reinforcement learning; AP switch ON OFF; energy efficiency; Cellfri massiv MIMO; multiobjektiv optimering; djup förstärkningsinlärning; AP switch ON OFF; energieffektivitet;

    Abstract : As a novel beyond fifth-generation (5G) concept, cell-free massive MIMO (multiple-input multiple-output) recently has become a promising physical-layer technology where an enormous number of distributed access points (APs), coordinated by a central processing unit (CPU), cooperate to coherently serve a large number of user equipments (UEs) in the same time/frequency resource. However, denser AP deployment in cell-free networks as well as an exponentially growing number of mobile UEs lead to higher power consumption. READ MORE

  3. 2. A Study on Data-driven Methods for Selection and Evaluation of Beam Subsets in 5G NR

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

    Author : Nic Ekman; Ilias Theodoros Skordas; [2022]
    Keywords : 5G; NR; telecom; telecommunications; ML; machine learning; algorithms; beam; widebeam; propagation; beamforming; subset; RAN; radio; radio environment; ericsson; Technology and Engineering;

    Abstract : 5G New Radio is the next generation of mobile networks and it comes with promises of ultra-high speeds, ultra-high reliability and ultra-low latency. This has posed a challenge for the engineers entrusted with the task of finding solutions which could fulfil the specification, and as a result, some promising areas have received increased attention in recent years.

  4. 3. Sockerbetssorters motståndskraft till mekaniska skador och dess inverkan på lagringsduglighet : en ”fall” studie

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Madeleine Nilsson; [2020]
    Keywords : sockerbetor; pressure; lagring; mekaniska skador; röta;

    Abstract : Lagringsperioden för sockerbetor har de senaste årtiondena förlängts på grund av strukturrationalisering och avreglering av kvotsystemet. Långa kampanjer är viktigt för att hålla nere de fasta kostnaderna och bibehålla konkurrensförmågan. För att lyckas med lagringen är det flera parametrar som är viktiga, där ibland sortvalet.

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Wenting Jin; [2017]
    Keywords : ;

    Abstract : Software level optimization for compilers has become a major research field.Dynamic Voltage Frequency Scaling (DVFS) technology gives some options for optimization, such as tweaking the voltage or frequency. READ MORE

  6. 5. A Method for Driving the Solar Control Mechanism Selection

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Vitaliya Mokhava; Christopher Nilsson; [2017]
    Keywords : Solar control mechanisms; Thermal comfort; Overheating; Solar control glass; Solar control blind; Technology and Engineering;

    Abstract : Highly glazed spaces are continuously increasing in popularity due to architectural attractiveness. However, increased use of glass often jeopardizes thermal comfort in several ways and problem of overheating is one of them. A way to face this problem is to appropriately use solar control mechanisms. READ MORE
