Customer retention is a key priority for mobile telecommunications companies, as acquiring new customers is significantly more costly than retaining existing ones. A major challenge in this field is predicting customer churn—users discontinuing services. Traditional predictive models such as rule-based systems often struggle with the complex, non-l...

Frequency-stabilized lasers are fundamental topics in research relating to optical frequency and wavelength standards. The absolute frequencies and hyperfine structures of the R(106)50-0, R(100)49-0, R(84)47-0, R(59)45-0, P(82)47-0, and P(71)46-0 lines of molecular iodine (127I2) at 514 nm were measured using a frequency-stabilized laser based on m...

This paper is about sustainable Electromagnetic Metamaterials (EM-MM), which are a new class of artificial materials with unique electromagnetic properties that cannot be found in nature. These materials are made from discrete micro and nanoscale objects which resonate, allowing for precise control over how they interact with electromagnetic waves,...

This thesis presents an in-depth examination of Mobile Robotic Telepresence (MRP). The work uncovers the social organisation of interactions and highlights the practical considerations of using the technology in organisational spaces. MRP systems are remotely controlled, mobile robots with video-conferencing capabilities. A remote user can drive th...

The influence of various trivalent lanthanides was investigated in the silica phosphate multi-component glass matrix, synthesized by the sol-gel method. The prepared glasses were analyzed to explore the degree of bandwidth amplification for telecommunication systems, and the potentiality of lasing media and smart glass films. Alkaline earth metal i...

Previous work has shown that technology can facilitate the communication of emotions, social touch, and social presence through haptic devices, meaning devices that provide a haptic stimulation. However, for special user groups living in long-term care facilities, such as people with dementia, the applications of these haptic devices are not appare...
