  1. 11. Sustainability demands on internal and external providers of IT

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Emma Lenman; Ida Appelgren; [2023]
    Keywords : sustainable IT; sustainability; IT; green IT; data governance; energy efficient; greenhouse gas emissions;

    Abstract : The use of IT in companies is constantly expanding, and therefore, so is the energy consumption and carbon footprint from IT. If companies do not take steps towards more sustainable IT usage, the footprint will continue to expand, toxic metals will be used in hardware and the usage of world resources will not become more circular.

To improve health, quality of life and task performance, integrative lighting is designed to give the right light at the right time at the eye to stimulate circadian entrainment. READ MORE

  4. 14. Ranging Error Correction in a Narrowband, Sub-GHz, RF Localization System

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

    Author : Silvia Barrett; [2023]
    Keywords : Localization; Narrowband; Sub-GHz; Radio Frequency; RSSI; Time-of-Flight; Error mitigation; Machine Learning; Linear Regression; LeastSquares Support Vector Machine Regression; Gaussian Process Regression; Loalisering; Narrowband; Sub-GHz; Radiofrekvens; RSSI; Time-of-Flight; Felkorrigering; Machine Learning; Linear Regression; LeastSquares Support Vector Machine Regression; Gaussian Process Regression;

    Abstract : Being able to keep track of ones assets is a very useful thing, from avoiding losing ones keys or phone to being able to find the needed equipment in a busy hospital or on a construction site. The area of localization is actively evolving to find the best ways to accurately track objects and devices in an energy efficient manner, at any range, and in any type of environment. READ MORE

  5. 15. Faradaic Reactions in Capacitive Deionization : A Comparison of Desalination Performance in Flow-through Cell Architectures

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : John Bradley; Miranda Carlström; [2023]
    Keywords : Capacitive deionization; Faradaic reactions; Flow-through CDI; Upstream anode; Downstream anode; Desalination Performance; pH fluctuations;

    Abstract : Capacitive Deionization (CDI) is an energy-efficient desalination technology that utilizes an electric field to extract ions from water. Flow-through CDI systems show potential for superior desalination performance compared to traditional flow-by CDI; however, they face the challenge of increased occurrence of Faradaic reactions, leading to undesired by-products and reduced energy efficiency.
