Nowadays, the classic operating systems are used on small dedicated devices that usually have restricted hardware resources. The study topic is focused on porting operating systems on such devices. Optimization of the needed functions against the available hardware resources may be done. OS Linux may be used for this purpose.
With the increasing amount of mobile data traffic and number of connected devices, the need for highly efficient algorithms to manage heterogeneous radio resources in the 5th generation of mobile networks, which are expected to be commercially deployed in horizon of five years, is even more evident. Moreover, the ability to self-organize the network parameters is an important element of future cellular networks, mainly because of their growing complexity and extremely high transmission demands of some mobile applications. A complex structure of the future cellular networks (containing e.g. femto cells or communications simultaneously utilizing different radio access technologies) imposes new challenges in management of these networks. With the growing network’s size and complexity, also the amount of resources, that are needed to maintaining the network, are increasing. Following that, the main task of this doctoral thesis is to survey state-of-the-art of 5G technologies and consequently design new algorithms for heterogeneous radio resources management in 5G mobile networks. The proposed algorithms will be verified and evaluated by selected simulation tools and also directly in the experimental LTE-A network.

Therapy processes addressing brain damage rehabilitation are more productive and achieved improvements more sustainable if they are provided systematically and continuously, optimal to the patient needs. The traditional model assuming rehabilitation conducted in highly-specified rehabilitation centers (clinics) that involves therapy pauses due to the high costs and resource lacks doesn’t support this aim. Therefore, there are already efforts to provide therapy at homes equipped with appropriate technical resources too. Providing home therapy addressing brain balance disorders, a significant category of brain damage impairments, is a good example. A long-term vision of modern treatments is data-centric. The captured data sets involve primary data gathered, e.g., by body sensors and a balance training equipment (e.g., balance force platform) and derived data, e.g., statistical and data-mining models. It is assumed that the future therapy developments will be based on a distributed network involving cooperating rehabilitation centers Each center coordinates a set of associated homes. There are many challenging requirements including data and therapy parameter security, reducing impacts of Internet connection interrupts, synchronization of collected data and extracted models. Cloud and Dew computing will play important role in this development. Dew computing is an emerging new research area and it is a challenging research issue to explore its great potential in applications. In this paradigm, the on-premises computer power provides functionality that is independent of cloud services and is also collaborative with cloud services. This Doctoral Thesis investigates a category of life-science applications with focus on brain damage rehabilitation, specifies requirements on a framework supporting productive development of such applications, designs an appropriate architecture, and experimentally implements a kernel functionality of the framework. The application set considered involves the balance disorder application in Prague and Parkinson’s Disease application in Brno. The suggested technology-based solution makes steps forward that each patient gets truly individualized training even at his/her home.

Electroencephalography evaluates spontaneous electrical brain activity through electrodes placed on the hairy skin of head. Specific changes on electroencephalogram (EEG) enable to differentiate patients with dementia with Lewy bodies (DLB) and dementia in Parkinson’s disease (PD) from healthy controls and patients with Alzheimer’s disease. Nowadays, it is possible to assess temporal and spatial patterns of EEG signal changes in various frequency bands, e.g. to explore relative frequency of specific EEG microstates. This method had not yet been used in patients with PD/DLB but there is some data suggesting that increased occurrence of specific EEG microstates might help to identify those at risk for hallucinations and cognitive fluctuations. Transcranial sonography (TCS) is a widely used method in medicine based on the Doppler principle and employed e.g. for evaluation of blood flow in vessels, imaging of organs in the abdominal cavity or for evaluation of heart function. Using TCS through so-called temporal window it is also possible to visualize some brain structures. Hyperechogenicity of substantia nigra is associated with iron deposition in this subcortical mesencephalic region and it is an early marker of PD/DLB. The main goal will be to combine these non-invasive techniques in order to identify those at prodromal stages of both diseases, i.e. prior to development of specific clinical symptoms that are necessary for clinical diagnosis. The research will be held in cooperation with from St. Anne's University Hospital in Brno and Central European Institute of Technology.

Examination of the common carotid artery (CCA) based on ultrasound measurements is an effective method for detecting cardiovascular diseases. In particular, the spatial evolution of the CCA wall is related to diagnostically relevant parameters describing, e.g., CCA tissue elasticity. Accordingly, the goal of this PhD thesis is to estimate the time-varying contour of the CCA wall from an ultrasound video sequence. This is to be achieved by developing a sequential extension of a machine learning method known as Gaussian process regression (GPR). In the GPR method, a function to be learned is represented by a random process, which avoids an explicit parametric representation. The desired sequential extension of the GPR method should be able to continuously track the detailed shape of the CCA wall over a time period of arbitrary duration.

The scenario considered in this PhD thesis is a network of agents that collaborate in order to track a moving target in a distributed (decentralized) manner. Here, "distributed" means that there is no central unit collecting and processing all the measurements, and only agents that are spatially close are able to communicate. In many methods for distributed target tracking, statistical information is exchanged between the communicating agents, and the underlying probability distributions are sparse. The goal of this PhD thesis is to develop and study “sparsity-exploiting” methods for distributed target tracking with reduced communication requirements.

Brain disorders occur when our brain is damaged or negatively influenced by injury, disease, or health conditions. Balance disorders create a significant category of brain damage impairments. The underlying hypothesis of the considered novel data-centric research approach is that detailed monitoring and continuous analysis of the data produced during patient’s rehabilitation exercise on modern balance force platforms complemented by patient´s physiological data integrated with data captured from other sources can help to optimize the therapy w.r.t. the current needs of the patient, to improve the efficiency of the therapeutic process, and to prevent patient overstressing during the therapy. The aim of this Doctoral Thesis is to develop an adaptive optimization (optimal selection and adjustment of therapy parameters from a large parameter value space) of involved therapeutic processes including precise monitoring, assessment, learning, and response cycles. This research will be conducted in cooperation with researchers from CVUT and Univerzita Karlova Praha (UK), who perform balance training (and collecting appropriate data) in rehabilitation centers built on their two home-grown systems: Homebalance - a system enabling balance training and Scope – a system collecting physiological data. Here, a set of sensors is capturing and storing large sets of data. In the initial phase, data provided by UK will serve as a source of positive and/or negative examples of interventions expected from adaptive optimization.

Currently, the Internet of Things (IoT) is one of the most dynamic branches of Information and Communication Technologies (ICT). Already today, the range of IoT applications is extremely broad, from wearable fitness trackers to connected cars, spanning the industries of utilities, transportation, healthcare, consumer electronics, and many others. However, we are only beginning to witness the true explosive growth of the IoT, with 10 billion MTC devices connected presently and 24 to 50 billion total connections expected within the following 5 years. However, the IoT of today is an unnecessarily complex and potentially vulnerable heterogeneous ecosystem, which embodies diverse connectivity between various types of networks across multiple communication technologies (such as ZigBee, WirelessHART, 6LoWPAN, legacy WiFi and Bluetooth, ISA100.11a, MiWi, BACnet, Z-Wave, NB-IoT, LoRa, Sigfox, etc.). The pressing challenge to construct a holistic connectivity infrastructure requires to make radical changes to how MTC systems are built, deployed, maintained, and used. Therefore, the main goal of this doctoral thesis will be research of universal communication architecture suitable for emerging customer and as well as industrial IoT applications with the strong focus on reliability and security. The thorough assessment of proposed solutions will be done in the simulation tools as well as via experimental implementations.
There are many services available on the Internet, such as large capacity data storage and server hosting (for example www, ftp). These services are commonly virtualized for an effective use of hardware resources. The study topic will cover analysis of virtualized services and their optimal use.
The topic is focused on side-channel cryptanalysis and research in countermeasures.

Doctoral thesis deals with transmission of multimedia data in IoT and wireless sensor networks. The aim of a research is to perform a study of possibilities that allowing transmission of multimedia data on devices with limited computing resources and design and development of algorithms ensure transmission of multimedia data with emphasis on high security, low latency and efficient usage of device's resources.
All Internet users have certain networking behavior: are visiting some subset of web pages, are members of given groups on social networks, are using another Internet tools like Skype. User obviously keeps his behavior even in case of traveling where the user is presented under various IP addresses. The goal of this work is to study possibilities of user identification based on his/her communication practice. That means e.g. (but not only) visited web pages, duration of staying on given web page, order of web pages visited, etc. It is necessary to take into account varying connection speed and any other parameters which might influence quantitative description of user behavior. Next goal of this work is to estimate the probability of correct user identification based on his/her networking behavior.
