Analysis of discrete event systens and synthesis of the knowledge-based control systems and intelligent control systems for them.
Analýza systémov diskrétnych udalostí a syntéza systémov ich znalostné ho a inteligentného riadenia
Program: VEGA
Project leader: Doc. Ing. Čapkovič František CSc.
Duration: 1.1.2006 – 31.12.2008

Annotation: Discrete event systems (DES) are more and more extended – not only in production, transport, communication (including Internet), etc. – but also in socio-economic systems. To control DES behaviour being awaken to the aim, it is necessary to have at disposal their mathematical model as well as to analyse their properties. Classical methods are unsufficient. Consequently, it is necessary to find new control systems able to deal with DES dimensions and complexity as well as with problems concerning the effective operation of DES. Knowledge-based control systems (utilizing a knowledge base properly representing knowledge about environment in which the system operates and about conditions imposed on the system operation) and intelligent control systems created on the base of distributed artificial intelligence, e.g. emergent systems like fractal production systems, multiagent systems, etc. with elements of adaptivity, learning and selforganization) are such systems. The main aim of the project is to analyse DES from such a point of view (i.e. the kind of the system, area and way of of their application, expected effect, etc.), to find suitable analytical models, suitable methods of knowledge representation, suitable menthods of applied artificial intelligence and to utilized them effectively in the process of the synthesis of the knowledge-based and intelligent control systems. Inseparable part of such an approach is also the verification of the models and proposed control algorithms in the proces of the computer simulation.
Automatic assessment of acute stress from speech.
Automatické hodnotenie akútneho stresu z reči
Program: VEGA
Project leader: Ing. Rusko Milan PhD.
Duration: 1.1.2018 – 31.12.2020

Annotation: A person often intuitively identifies whether his/her partner in conversation is under stress, just from stress manifestations in the voice and speech. However, the group of acute stress manifestations and their measurable acoustic cues are not known well. There are no suitable speech databases available to study these manifestations. We will design an experimental scenario when the subject is stressed and is forced to communicate intensely via speech. During the experiment other modes, such as video, biosignals (pulse, skin conductivity, …), will be recorded in addition to speech. We will analyze the collected data and propose an annotation scheme to capture the occurrence of stress. We will investigate the effects of stress and their acoustic correlates and select a set of acoustic features and a suitable machine learning method for automatically identifying stress in speech. A system for stress detection from speech will be developed and its results will be compared to subjective expert judgment.

Annotation: Motivation of this project comes out the research of new 2D materials such as metal sulfides and from the present state of development of e-beam lithography (EBL) as one of the alternative methods of 2D structures preparation in electronics. This project is focused on obtaining new scientific results in the patterning of nano-scale structures (10-100nm) in electron resists. Attention will be paid to the research of the influence of the electron lithography processes on the resulting nanometric patterns patterned in electron resits in term of resolution, dimensionsaccuracy and edge roughness of the structures in the resist. We will study the parameters influencing the profile of the nanometric patterns in polymeric resists. The simulations of lithographic parameters of electron resists onthin semiconductor layers, nitride membranes and layers with 2D materials, are an important part of this project.

Program: VEGA
Project leader: Doc. RNDr. Laclavík Michal PhD.
Duration: 1.1.2010 – 31.12.2012

Annotation: At present the amount of information available in digital form is increasing steadily. However, increasing volumeresults in so-called information overload – i.e. much information is available which we are unable to sort, integrateor retrieve adequately. The largest group of digital data is that created by humans, such as text, documents,pictures, videos. The onset of web 2.0 applications and of electronization of banking or travel transactions resultsin generating huge amount of data. However, data generated in the above manner contain much information,primarily about links among real world and digital objects, but this valuable information is hard to find in the hugevolumes of available data. The project handles research and development of such methods which would makethis partially possible. Simultaneously, the project is aimed at analysis, creation and verification of suchinformation processing methods and algorithms which are able to process, manage, retrieve and accessinformation large scale.

Web page: http://ikt.ui.sav.sk/vega/
Annotation: An important aspect in building knowledge economy is an ability of organizations to assess their knowledge capital. Technologies and knowledge are becoming a key factor in productivity growth. This is the reason why companies support knowledge management projects in their organizations and strive to use their knowledge management to the largest possible extent. The objective of the project is to support companies heading towards the knowledge economy by extending existing and creating new models, algorithms, technologies and tools that can help organizations in their transition to a knowledge oriented corporation. Such transition should be preceded by an analysis and processing of information resources in organizations including documents, electronic communication and databases in an effect to manage and create availability and sharing of relevant information and knowledge. The project focuses in particular on the areas of knowledge modeling, service oriented architectures, distributed knowledge bases, semantic annotation, knowledge mining, case based reasoning and statistical methods. Special attention is devoted to processing of information resources in the Slovak language, where techniques based on neural networks and ontologies will be used.

Program: VEGA
Project leader: Doc. Ing. Čapkovič František CSc.
Duration: 1.1.2013 – 31.12.2016
Web page:
Annotation: Systems in practice (manufacturing, transport, communication, supplaying, etc.) have not only a complex structure but they also comprehend subsystems of different fundamentals:continuous, discrete-event and hybrid (different combinations of previous ones). Therefore, their control is complicated too. It is necessary to decentralize control by means of intelligent subsystems – agents. Cooperation of autonomous agents by a properly designed supervisor can ensure attainment of the global goal of the complex system. Petri nets (PN) of different kinds – place/transition PN (P/T PN), timed, hybrid – will be used to model DES and hybrid systems. P/T PN will be used also for the supervisor synthesis, namely at first their invariants (especially P-invariants), state vectors of places and transitions, possibly the Parikh\’s vector too, but also other parameters and properties. Constraints imposed on the supervisor synthesis will reflect the real goals to be achieved (often formulated only verbally) in analytical terms.

Mechatronic vision system
Mechatronický vizuálny systém
Program: VEGA
Project leader: Doc. Ing. Dobrovodský Karol PhD.
Duration: 1.1.2010 – 31.12.2012
Web page: 12 000
Annotation: A mechatronic vision system for automatic perception and monitoring of static and moving objects is proposed. The system consists of several relatively independent subsystems cooperating in order to achieve the common goal to recognize the existence and the motion of a relatively small object from the background, to report it‘s position, velocity and acceleration, to predict the motion and to support tracking of the moving object. The combination of an automatic recognition subsystem with an automatic object motion prediction and camera orientation control facilitates the ability of the whole system to work autonomously in real time. The system will be designed in a modular way to enable simple adaptation to several static and mobile cameras mechanically oriented in space by the two degrees of freedom. The open architecture of the system allows group management integration, day and night image processing, and various geometric computation.

Program: VEGA
Project leader: Doc. Ing. Čapkovič František CSc.
Duration: 1.1.2009 – 31.12.2012

Annotation: The project is focused on the research of decentralised control of systems by means of intelligent controlsubsystems and control agents. Because the behaviour of such subsystems depends on the occurrence ofdiscrete events, they will be modelled by methods used for discrete event systems (DES), epecially those basedon Petri nets. However, the modular approach will be used. It will be possible to join separate moduls into highercomplexes by means of arbitrary interconnections. Such a model of the control system will be able to expressexplicitly mutual interconnections among the moduls. This allows to examine the impact of the interconnectionson the effectiveness of the control of the controlled object. The design of suitable methods and algorithms of thepurposeful cooperative interaction among moduls is the main goal of the project. Proposed approaches will beprogrammed in the MATLAB environment. They will be verified by simulation in MATLAB at the control ofselected kinds of systems.

The achieved results have shown existence of variety techniques and their hardware solutions, standards for (self-) testability, but they haven not always to be applied by optimum and effective way. The optimization of existing and new developed methods is based on the achieved knowledge and experiences and is solved with respect to important parameters: test time, power consumption, overheads and cost needed for (self-) testing and fault diagnosis. The research object is a digital system implemented into FPGA or ASIC that consists of different digital blocks – cores (pre-designed or glue logic). The testing standards: IEEE 1500 SECT (the standard for embedded cores), IEEE 1149.1 “Test Access Port and Boundary Architecture” (JTAG), existing self-test techniques based on linear feedback shift registers (LFSR), cellular automata and data compaction and compression techniques are initial methods of the project. The expected contribution is in new algorithms and techniques, their optimum hardware and software implementation with regards to mentioned parameters and a system of their automatic synthesis to VHDL digital circuits and systems models.

Program: VEGA
Project leader: Ing. Dobrucký Miroslav
Duration: 1.1.2007 – 31.12.2009

Annotation: Continuously increasing costs of mineral resources and the requirement for our products to be competitive make us using our material resources more efficiently. Numerical calculations on a mesoscale level, where a material is idealised as a continuum, play an important role in optimization of various constructions and technological processes. The finite element method (FEM) is the most widespread from among the aforementioned calculation methods which uses a material tension diagram as one of its entries. The accuracy of these calculations is essentially affected with the accumulated plastic strain versus true stress relationship determination of the material coming from a tensile test. This material characteristics can be considered accurate as far as the stress state during the test remains uniaxial, that is no necking occurs. The aim of this project is to supplement the tension test with sufficient mathematical tool to determine the accumulated plastic strain versus true stress curve during necking and to get a better outlook on the stress distribution in the material. This improvement in the aforementioned material characteristics determination will increase in general the calculation accuracy as well as improve the numerical response prediction mainly in large strain / large deflection area with considerable plastic deformations, which eventually decreases the cost of experimental tests and increases the work efficiency.

Program: VEGA
Project leader: Ing. Baláž Marcel PhD.
Duration: 1.1.2015 – 31.12.2018

Annotation: Complex systems integrated on a chip are becoming ubiquitous in many applications; so their operation must be reliable and resistant to failure, even though the nanotechnologies enhance their failure rate as a result of newfault mechanisms. Reliability of systems-on-chip (SoCs) is becoming a critical parameter and often could be achieved only at the expense of other parameters quality, such as consumption and chip area. The project aims to research on new architectures with built-in self-repair suited to different types of digital IP cores embedded inSoCs. In addition to standard cores such as processors, controllers, and other combinational cores, the project focuses on the so-called specialized cores, for which there are currently no methods to increase their reliability.The proposed architecture will be verified by simulation through the available software tools and experimentally using programmable devices. The results of the project will contribute to increasing reliability and life-cycle of SoCs.

Program: VEGA
Project leader: Mgr. Šeleng Martin PhD.
Duration: 1.1.2013 – 31.12.2015

Annotation: The knowledge bases research was represented in the past decade by semantic Web and knowledgemanagement. New opportunities to tackle this challenge came with new Internet technologies and services, such as social networks, Wikipedia and vast amount of structured data (LinkedData, government data, community data) in the form of lightweight semantic networks. New methods for information and knowledge processing, integration, inference, search and visualization can be designed and tested using such networks. Lightweight semantic networks and graphs are not represented by strict semantic model, but they evolve based on new data, resources integration, systems and user interaction and they can be used for new types of knowledge bases. The research challenges of unstructured data (web, text and documents) processing still remain. We will research and develop methods for the creation and use of knowledge bases built from structured and unstructured data.

Annotation: The aim of the project is design and implementation of new reliably solved architectures for digital systems fault diagnosis and fault self-repairing. Testing of complex digital systems on chip requires more and more hardware blocks, such as self-test generators, compression and decompression units, signature analysers, standard interfaces for embedded core inputs and outputs accessibility, and different types of control units. Increasing test hardware overhead, a new problem arises, namely its reliability. Project results will help to improve the quality of testability, reliability and operating life of digital systems by introducing new strategies and procedures, which will connect methods of concurrent and off-line diagnostics in systems, as well as in blocks determined for those systems testing. Proposed new methods will be verified by their applications to real digital systems using the FPGA technology. The selection will be targeted at systems for data encryption algorithms, image and audio processing.
Processing of sensor data via Artificial Intelligence methods.
Spracovanie údajov zo senzorov prostriedkami umelej inteligencie
Program: VEGA
Project leader: Ing. Malík Peter PhD.
Duration: 1.1.2019 – 31.12.2022

Annotation: The project will propose new methods and algorithms for processing of multi-sensor data for tasks of object diagnostics, areas of interest evaluation, secure communication and simplification of the new intelligent models creation. The research will focus on advanced methods of artificial intelligence with emphasis on deep learning. Artificial Intelligence algorithms show significantly better results than traditional methods, and an example of this is the tremendous progress of refining semantic image segmentation through deep learning over the last five years. Modern, low-cost, miniature electro-mechanical structures allow simple integration and group deployment of multiple sensors, resulting in the production of a huge amount of multi-sensor data that can not be manually processed. The project output will include new models of accurate semantic image segmentation, precision object modeling, multiple sensor collaboration models, and secure data transfer, especially for the Internet of Things and Industry 4.0.

Program: VEGA
Project leader: Ing. Rusko Milan PhD.
Duration: 1.1.2015 – 31.12.2017

Annotation: The project is aimed at checking up the possibility of using the speaker verification (SV) as an add-on safety element in the ATM security. The objective of the project is to study the properties of this communication and to verify whether it would be possible to use the speaker verification system to verify the identity of the speakers and to unavil a potential entry by an intruder in this communication. In this project we want to focus on the initial assessment of the involvement of the speaker verification technology in the ATM security system. The SV and its resistance to fraud attacks will be performed in the Slovak languge too. A set of speech recording samples of 500 speakers will be prepared a unique set of 500 corresponding synthesizers with wide range of settings will be created, which together with the existing synthesizers will be used to prepare data for imitated attacks. The complex calculations related to training and evaluation will be realized on the computer cluster of the II SAS.

Program: VEGA
Project leader: Ing. Baláž Marcel PhD.
Duration: 1.1.2012 – 31.12.2014

Annotation: Maintaining the reliability of the digital system during its lifetime becomes the most important challenge for the current semiconductor industry. It is required to design highly reliable systems even if the system components reliability shows the decreasing tendency due to new fault mechanisms in the modern nanotechnologies. Reliability of complex systems integrated on a single chip is not possible without the implementation of self-repair capability. Application of such architectures is well known for memory circuits and other regular structures. The goal of the proposed project is the development of new methods for designing built-in self-repair architectures for circuits with irregular structures (combinational and sequential logic circuits). The developed methods will be evaluated on selected types of logic cores by simulation using available software tools and programmable circuits. The results of the proposed project contribute to the reliability increase of the systems-on-chip.
