Historically, software production methods and tools have a unique goal: to produce high quality software. Since the goal of Model-Driven Development (MDD) methods is no different, MDD methods have emerged to take advantage of the benefits of using conceptual models to produce high quality software. In such MDD contexts, conceptual models are used as input to automatically generate final applications. Thus, we advocate that there is a relation between the quality of the final software product and the quality of the models used to generate it. The quality of conceptual models can be influenced by many factors. In this thesis, we focus on the accuracy of the techniques used to predict the characteristics of the development process and the generated products. In terms of the prediction techniques for software development processes, it is widely accepted that knowing the functional size of applications in order to successfully apply effort models and budget models is essential. In order to evaluate the quality of generated applications, defect detection is considered to be the most suitable technique. The research goal of this thesis is to provide an accurate measurement procedure based on COSMIC for the automatic sizing of object-oriented OO-Method MDD applications. To achieve this research goal, it is necessary to accurately measure the conceptual models used in the generation of object-oriented applications. It is also very important for these models not to have defects so that the applications to be measured are correctly represented. In this thesis, we present the OOmCFP (OO-Method COSMIC Function Points) measurement procedure. This procedure makes a twofold contribution: the accurate measurement of objectoriented applications generated in MDD environments from the conceptual models involved, and the verification of conceptual models to allow the complete generation of correct final applications from the conceptual models involved. The OOmCFP procedure has been systematically designed, applied, and automated. This measurement procedure has been validated to conform to the ISO 14143 standard, the metrology concepts defined in the ISO VIM, and the accuracy of the measurements obtained according to ISO 5725. This procedure has also been validated by performing empirical studies. The results of the empirical studies demonstrate that OOmCFP can obtain accurate measures of the functional size of applications generated in MDD environments from the corresponding conceptual models. / Marín Campusano, BM.

<p>U disertaciji je prikazan i predložen novi metod merenja snage<br />i energije vetra koji se bazira na stohastičkoj digitalnoj mernoj<br />metodi (SDMM), umesto do sada korišćene standardne sempling<br />metode (SSM). Standard za merenje brzine vetra predstavlja<br />anemometar sa šoljicama, koji na svom izlazu daje sinusni napon<br />čija su amplituda i frekvencija linearno zavisne od brzine<br />vetra. Kako su snaga i energija vetra proporcionalne trećem<br />stepenu brzine vetra, u tu svrhu se primenjuje generalizovan<br />hardver namenjen za računanje proizvoda tri ulazna signala. Zbog<br />niskog frekvencijskog opsega ulaznog signala izvršeno je<br />značajno pojednostavljenje hardvera mernog uređaja. Teorijskom<br />analizom, simulacijom, a potom i eksperimentom potvrđena je<br />hipoteza istraživanja, da se SDMM uspešno može koristiti za<br />merenje snage i energije vetra.</p> / <p>In this dissertation а new wind power and energy measurement<br />method, based on Stochastic Digital Measurement Method (SDMM),<br />was elaborated and proposed, to replace the commonly used Standard<br />Sampling Method (SSM). The standard for wind speed measurement is<br />a cup anemometer that provides a sinusoidal voltage on its output,<br />having the amplitude and frequency linearly dependent of the wind<br />speed. Since the wind power and energy are proportional to the third<br />degree of the wind speed, the general case hardware has been designed<br />for the product calculation over three input signals. The low frequency<br />range of the input signal allows for a significant simplification of the<br />measuring instrument hardware. By theoretical analysis and<br />simulation, and consequently through an experiment the hypothesis of<br />this research was confirmed - that SDMM can be successfully used to<br />measure wind power and energy.</p>

This thesis is focused on the description of the method of reactive sputtering of thin films. Currently, there are many ways how to create thin films and there are many applications of thin films in various industrial sectors. In this paper at the first are listed the issue of thin films, followed by an overview of the deposition techniques and of the chemical analysis of deposited thin films. It also describes the four-point measurement method of sheet resistance, mechanical test of adhesion and optical properties. At the end of the theoretical part are described the material composition of the deposited films. The goal of the practical part is to optimize the deposition process of the mixed layer of indium tin oxide (In2O3: SnO2) and contribute to the overall understanding of the influence of annealing on the layer. There were created six series of samples with that applied layers. First, the work focused on examining of the influence of annealing on the throughput in the whole measuring range, and then comparing the series due to the transmittance in the visible light spectrum. Furthermore were compared the value of sheet resistance of unannealed and subsequently annealed samples.

The presented dissertation thesis analyses artefacts in diffusion-weighted images. In medical practice, the artefacts can impede the diagnostics of pathological tissues and, therefore, need to be eliminated. As the first step within the thesis, an analysis of the most frequent artefacts in diffusion-weighted images is performed, and the hitherto known approaches to artefact elimination are described. In order to facilitate the reduction of artefacts caused by the inhomogeneity of the static magnetic field and induced by eddy currents, a novel three-measurement method is shown. This technique will find application especially in measuring the diffusion coefficient of isotropic materials. At this point, it is important to note that a significant and commonly found problem is the magnetic susceptibility artefact; different magnetic susceptibility values at the boundary between two materials can cause magnetic field inhomogeneities and even complete loss of the signal. Therefore, we designed a novel method for the measurement of magnetic susceptibility in various samples of magnetically incompatible materials, which do not produce any MR signal. The technique was experimentally verified using a set of differently shaped diamagnetic and paramagnetic samples. In addition to the magnetic susceptibility problem, the thesis presents artefacts such as noise, motion-induced items, hardware limitations, chemical shift, and the dependence of the diffusion coefficient on the temperature. To enable precise measurement of the diffusion coefficient, we proposed a thermal system; in the experiment, it was determined that when the measurement error does not exceed 5%, the temperature change should not be higher than 0,1 °C. In the final sections of the thesis, practical application examples involving the designed methods are shown.
