The integrated impact of artificial gravity and vibration exercise training on muscle structure and function
During space sojourns, astronauts experience musculoskeletal deconditioning caused by the lack of gravity. The adaptation of the musculoskeletal system to inactivity and unloading of the weight-bearing limbs may be countered by daily exercise. However, current exercise devices and strategies employed on the International Space Station (ISS) do not appear to …
Pneumatic variable stiffness mechanisms for application in lower-limb exoskeletons
Wearable robotics holds promise for enhancing human capabilities and addressing motor challenges in individuals with impairments, amputations, or those who are healthy. Exoskeletons, among various wearable devices, are designed to be worn on the upper or lower limbs. While some applications, like in the medical field, have been widely adopted, …
Topology-induced phenomena and caloric effects in condensed matter
The first part of the thesis deals with the impact of surface-functionalized nanoparticles (NP) can have on the stability of liquid crystal (LC) phases. Experimental data of NP concentration-driven phase transition between the isotropic and nematic phase in 5OO8 LCs were used to create a minimal mathematical model that would …
Predictive exoskeleton control based on probabilistic models
Research and development of exoskeletons for injury prevention and assistance with everyday living has steadily increased in the last decade. With some products already available on the market, a widespread adoption of exoskeletons appears to be within close reach. However, many challenges still remain to be overcome, one of which …
The sensor hub for detection of the relation between physiological parameters and colour modifications in text background and overlay during reading in children with and without dyslexia
The doctoral dissertation discusses the mechanisms of the colours’ influence on the reading process and electrophysiological correlates of the reader's condition, considering developmental aspects, graded (level) aspects and gender aspects of tested groups of children and their reading acquisition. The reading process is one of the most important processes during …
Development of SiC-based composite material for fusion application
Nuclear fusion offers a prospect of a safe, economical and environmentally friendly source of energy. For the advanced concepts of nuclear fusion, SiC-based fibre reinforced composites were proposed as a structural material for the first wall of the reactor vessel, enabling higher operating temperatures and efficiencies. Already developed techniques for …
Normobaric hypoxia: Metabolic responses following 10-day hypoxic confinement
The aim of the present thesis was to examine the effect of normobaric hypoxic confinement on selected metabolic responses. This was investigated in two separate studies: Study I investigated the effect of normobaric hypoxia, as frequently used by athletes for altitude training, on metabolism. The metabolic responses were assessed in …
Modular gene dynamics and network theory at mesoscopic scale
Complex dynamical systems are often modeled as networks, with nodes representing dynamical units which interact through the network’s links. Gene regulatory networks, responsible for the production of proteins inside a cell, are an example of system that can be described as a network of interacting genes. The behavior of a …
