Evolucijski algoritam za dinamičko planiranje razdjelnih mreža
-
Minea Skok Dugoročno planiranje razdjelnih mreža pripada grupi kombinatoričkih problema kojima su svojstveni veliki broj realnih i cjelobrojnih nepoznanica, višestruki i međusobno oprečni kriteriji u funkciji cilja, veliki broj linearnih i nelinearnih ograničenja, veliki broj logičkih pravila, neodređenost ulaznih podataka i vremenska dimenzija. Stoga je primjena konvencionalnog, intuitivnog i iskustvenog, pristupa planiranju gotovo nemoguća. Primjena tradicionalnih matematičkih...

Extended-cavity optical sources with modulation averaging reflectors
-
Tin Komljenović Passive optical networks with wavelength multiplex (WDM-PON) allow high speed transmission in access networks, but have not yet been widely deployed primarily due to cost. Wavelength-agnostic transceivers at the user end in colorless WDM-PON systems offer significant cost reduction as each of the optical network units is identical. The cost and complexity of the system is further reduced by using self-seeded WDM-PON architectures in which a reflector at a remote node allows the...

Extending the recurrent neural network model for improved compositional modelling of text sequences
-
Martin Tutek The thesis focuses on exploring extensions to the recurrent neural network (RNN) algorithm for natural language processing (NLP) in terms of improving its capabilities of semantic composition, investigating the possible benefits of leveraging multi-prototype word representations and improving its overall interpretability. While RNNs have received a strong competitor in form of the Transformer model, both approaches to processing natural language sequences possess their own set of issues....

Extension of dynamic software update model for class hierarchy changes and run-time phenomena detection
-
Danijel Mlinarić Software maintenance requires a software update that causes unavailability during the update. Software downtime introduces costs in business processes and can negatively affect critical processes, such as the software controlling bank transactions or traffic systems. One of the solutions to provide software updating without interruption is Dynamic Software Updating (DSU). However, there are several challenges in dynamic software updating. It is necessary to detect changes between versions of...

Extension of the mediator-wrapper architecture for heterogeneous data source integration by
adding a mask
-
Juraj Dončević This doctoral research deals with the extension of the mediator-wrapper architecture for heterogeneous data source integration. Scenarios that require the addition of diverse system access interfaces where the mediator-wrapper architecture underperforms are identified. Therefore, an extension of the mediator-wrapper architecture is proposed by the addition of a new component type called a mask. The mask presents a new layer in the mediator-wrapper architecture, effecting the creation of a...

Extraction of movement related oscillatory changes from electroencephalogram with application to brain-computer interface
-
Ana Branka Jerbić A brain computer interface (BCI) is a technology that decodes a user's intent from brain activity. Obtained information can be used to control devices in the user's environment. In this thesis, changes in sensorimotor rhythms (SMR) during motor imagery (MI) are extracted from electroencephalogram (EEG). These changes are reflected in amplitude attenuation (event related desynchronization) or enhancement (event related synchronization) of SMRs in certain brain regions. Extracted features are...

Extreme limits in compaction of 110 kV overhead transmission line regarding dielectric stresses
-
Stanislav Vižintin At the beginning of my Ph. D. thesis, the state-of-the-art technologies are described as used in OL compacting. Physical bases are then discussed for any type of overvoltage phenomena taking place on OLs and principles as well as procedures are given for insulation co-ordination. A special attention is devoted to the deterministic and statistical method. Based on the analysis of the overvoltage conditions experienced in the Slovenian 110 kV network, the insulation level was determined by...

Extrinsic and temporal calibration of heterogeneous mobile robot exteroceptive sensor systems
-
Juraj Peršić Robust environment perception of a mobile robot strongly relies on fusion of multiple heterogeneous sensors. However, proper sensor calibration is essential for fusion. Extrinsic calibration tries to find transform between coordinate frames of two or more sensors. This thesis proposes a novel calibration target suitable for accurate 6 degrees of freedom calibration of radar-camera-lidar systems. Furthermore, measurements of the target enable two-step optimization which leads to accurate...

Fast distributed cross-matching of big astronomical data and parameter estimation of moving point source model
-
Petar Zečević The thesis develops two original methods: “Distributed Zones Algorithm” and “Online Multifit”. “Distributed Zones Algorithm” is a zone-based method for fast distributed crossmatching of big astronomical data. It is developed based on the Zones Algorithm and comprises a distributed data organization scheme and an efficient method of positionally joining data using a moving window. The algorithm is implemented within a system called AXS (Astronomical Extensions for Spark), based on...

Fast frequency control in low-inertia power systems
-
Matej Krpan The thesis evaluates the impact of increased penetration of power converters on the dynamic behaviour of power system frequency through the development of reduced-order dynamic models of converter-interfaced resources. The focus is on modelling wind turbine generators and supercapacitor energy storage for dynamic simulations of a power system with a high share of power electronic devices. The final goal of the research is to develop a low-order system frequency response model of a...
