The concept of systems accounts for the organization and patterns of order that characterize the natural world. Throughout the history of science, scientific activity has been based on this concept, either implicitly under a mechanistic approach or explicitly under an holistic systems approach. Contemporary science is now based on an holistic systems viewpoint that encompasses both the natural and social worlds as objects for study. Based on this context for the systems viewpoint, the thesis addresses archival constructs, arising spontaneously as a byproduct of societal activity, as instances of systems. This is an aspect of their nature that was recognized by traditional theorists, who devised the methodology that still fundamentally guides archival practice. However, the archival field has not yet recognized the applicability and utility of formal systems notions to the work of the archivist, specifically to the tasks of arrangement, description, and appraisal. The thesis argues that appropriate handling of archival constructs requires that they be treated as systems, that the concept of systems provides a necessary framework for archival theory, and that by adopting a systems viewpoint, the archival field may regain the status of a recognized profession and join with other fields of applied science that contribute to systems research. / Arts, Faculty of / Library, Archival and Information Studies (SLAIS), School of / Graduate

We show that the nonadditive open systems can be studied in a consistent manner by using a generalized version of S-theorem. This new generalized S-theorem can further be considered as an indication of self-organization in nonadditive open systems as prescribed by Haken. The nonadditive S-theorem is then illustrated by using the modified Van der Pol oscillator. Finally, Tsallis entropy as an equilibrium entropy is studied by using Boltzmann's method of orthodes. This part of dissertation shows that Tsallis ensemble is on equal footing with the microcanonical, canonical and grand canonical ensembles. However, the associated entropy turns out to be Renyi entropy.

The aim of this diploma thesis is an analysis together with an assessment of the current state of the information system of the selected company, with the subsequent proposal of specific solutions. One of the proposed changes is devoted to the issue of the process of calls for payment of invoices. These specific solutions should lead to the optimization of the selected process and the improvement of the current state of the system.

The thesis is focused on the description of the method for the selection of the information system for the company KOPS spol. Ltd. The work is based on theoretical knowledge for a proper understanding of the issue. In the next part, an analysis of the current state of the company is performed, while monitoring the factors influencing the company and especially the information system. The last part describes the procedure for selecting a system and the possibilities of its implementation to the company.

<p>The primary purpose of this paper is to propose a future direction of investigation: a more formalized approach to developing systems engineering methodologies and tools to support the system engineer and other disciplines in effectively applying the systems engineering process. This approach is based on the concept of using design principles to achieve specified objectives. The achievement of these objectives is indicated by the presence of defined attributes within the developed system. A secondary purpose of this paper is to illustrate how the concept of objectives, principles, and attributes provides a means for promoting an increased understanding of the similarities and interrelationships between systems engineering and other disciplines, particularly software engineering. A direct consequence of this increased understanding is an improvement in the application of the systems engineering development process.</p> / Master of Engineering
