<p>Primjena Internet protokola u uređajima sa ograničenim resursima, dovodi do radikalne promjene Interneta i pojave potpuno novog koncepta pod nazivom Internet stv&acirc;ri &ndash; Internet of Things (IoT), čiji je jedan od osnovnih gradivnih elemenata Senzor Web (SW) čvor. SW čvor predstavlja elementarni &ldquo;resurs&rdquo; u SW mreži koja se po svojoj prirodi može posmatrati kao nestrukturirana kolekcija gradivnih elemenata koji se mogu dinamički orkestrirati u virtuelne klastere, odnosno u arhi-tekturu. Cilj disertacije predstavlja unapređenje procesa razvoja arhitekture sistema baziranih na SW mrežama uz oslonac na dinamičko generisanje servisnog sloja u svrhu povećanja produktivnosti, održivosti i smanjenja troškova razvoja. Pod unapređenjem procesa razvoja arhitekture smatra se analiza, integracija i prilagođavanje postojećih sistema i pristupa projektovanja arhitekture senzorskih mreža, kao i sistema baziranih na IoT konceptima. U tu svrhu definisana je arhitektura SW mreža, kreiran domenski specifičan jezik, interaktivni grafički editor i alat za automatsku transforma-ciju modela u implementacione klase. U sklopu teze izvršena je i eksperimentalna verifikacija predloženog modela i razvojnog okruženja, čime je dokazana njhova praktična primjena.</p> / <p>The use of Internet protocols in limited resources devices contributes to radical changes in the Internet and the emergence of an entirely new concept called the Internet of Things (IoT), consisted of the Sensor Web (SW) nodes as one of the basic building blocks. SW node is the elementary &quot;resource&quot; in the SW Network, which by their nature can be seen as an unstructured collection of blocks that can be dynamically orchestrated into the virtual cluster, or in the architecture. The aim of this thesis is to improve the process of developing a system archite-cture based on SW networks, relying on the dynamic generation of the service layer in order to increase productivity, sustainability and cost of development. The improvement of the architecture development process includes analysis, integration and adaptation of existing systems and sensor network architecture design approaches, as well as systems based on the IoT concepts. For this purpose, the archite-cture of the SW Network is defined, a domain-specific language has been created as well as interactive graphics editor and a tool for automatic transformation of models into the implementation class. As part of the dissertation, the experimental verification of the proposed model and the development environment were carried out demonstra-ting their practical application.</p>

There are several frauds against biometric systems (BSs) and several techniques exist to secure BSs against these frauds. One of the techniques is liveness detection. To fool fingerprint sensors, latent fingerprints, dummy fingers and wafer-thin layer attached to the finger are being used. Liveness detection is being used also when scanning fingerprints. Several different characteristics of the live finger can be used to detect liveness, for example sweat, conductivity etc. In this thesis, new approach is examined. It is based on the expandability of the finger as an effect of heartbeats/pulsation. As the skin is expanding, also the distances between papillary lines are expanding. Whole finger expands approximately in range of 4,5 ľm , the distance between two neighbor papillary lines in 0,454 ľm . This value collides with wavelength of blue and green light. The result from this work is following. The resolution of the capturing device is not high enough to capture the expandability on distance between two neighbor papillary lines. Also, because of collision with wavelength, the diffraction effect is presented and the result images are influenced by this error.

This thesis deals with the subject of a mobile robot design for an international competition Minisumo. The work includes both a theoretical presentation of the robot design as well as the documentation of its realization. The development process starts with a creation of a theoretical basis, which is functioning as a source of information for the consecutive design of the mechanics, electronics and final production of the robot. The work also includes the development of control software necessary for the correct operation of the robot.

This document deals with presentation of nowadays software and hardware methods used for fingerprint recognition with focus on liveness testing and thereafter it deals with description of my solution. In order to describe results obtained from study of technical literature, we discuss important terminology of biometric systems at first and further main principles of fingerprint sensors used in practice are shown. From overviewed methods of liveness detection we underline one method based on  perspiration (researched by BioSAL laboratory) and one spectroscopic method researched by Lumidigm Corporation. The study of liveness testing methods inspired me to creation of new type fingerprint sensor which has built-in livennes testing method based on two characteristic properties of living human tisue. In order to test this sensor, we discuss nowadays sensor deception method. It follows from their analysis, that newly designed sensor should be theoretically resistant to each of them.

<p>Математички модели за естимацију тешко мерљивих величина називају<br />се софт сензорима. Процес формирања софт сензора није тривијалан и<br />квалитет естимације тешко мерљиве величине директно зависи од<br />начина формирања. Недостаци постојећих алгоритама за формирање<br />спречавају аутоматску конфигурацију софт сензора. У овом раду су<br />реализовани нови алгоритми који имају за сврху аутоматизацију<br />конфигурације софт сензора. Реализовани алгоритми решавају<br />проблеме проналаска оптималног сета улаза у софт сензор и кашњења<br />сваког од њих као и одабира структуре и начина обуке софт сензора<br />заснованих на вештачким неуронским мрежама са радијално базираним<br />функцијама.</p> / <p>Matematički modeli za estimaciju teško merljivih veličina nazivaju<br />se soft senzorima.

Rýchlosť vozidla je jednou z kľúčových stavových premenných, ktorej znalosť je potrebná v reálnom čase a s vysokou presnosťou, aby mohla slúžiť ako vstupná veličina pre systémy kontroly dynamiky vozidla. Jej priame meranie vo vozidle je však finančne náročné. Riešením tohoto problému môže byť použitie meraní zo senzorov bežne dostupných na palube vozidla a ich následný prepočet na rýchlosť vozidla. Tieto merania sú však veľmi zaťažené procesným šumom, čo vyplýva z komplexnosti pohybu vozidla. Preto je nutné vyvinúť algoritmus so schopnosťou vysporiadať sa s týmito negatívnymi vplyvmi. Algoritmus prezentovaný v tejto práci odhaduje pozdĺžnu rýchlosť vozidla s použitím meraní uhlových rýchlostí štyroch kolies, pozdĺžnej akcelerácie, momentov motora, rýchlosti otáčania okolo zvislej osi a natočenia volantu. Algoritmus bol testovaný na veľkom počte situácií považovaných za kritické na odhad rýchlosti vozidla, ako napríklad prudká akcelerácia na vozovke s nízkym koeficientom trenia, núdzové brzdenie s aktiváciou ABS, či jazda v kopci s kolesami v preklze, prinášajúc uspokojujúce výsledky.
