The goal of development of sound database for marine fishes in Taiwan not only preserves data, but also wants to provide a common ground of data sharing to increase the efficiency for the study of fish behavior, automatic recognition, localization, and tracking. In order to provide the sound quality in terms of signal-to-noise ratio to users, the fish sound recording will be analyzed before uploading. Because most available data were recorded either in the field or in fish tank, the fish sounds were extracted by using two different automatic detection methods. If fish sound recordings were from the field, the Time Endpoint Detection was applied by the processing a 0.5-s time frame with 50 % overlapping. Then the energy of the time frame was obtained by the sum of square of amplitude and the median of the energy plus a standard deviation was established as the threshold to extract fish sounds. If the recording was made in the fish tank, the Frequency Endpoint Detection was applied by 0.5-s time frame with 50 % overlapping. Then each time frame will be transformed into spectrum and the energy ratio of each frequency will be calculated from the spectrum. Finally the information entropy was obtained from the energy ratio and the detection threshold was set on standard deviation above the median of the information entropy. From two different automatic detection methods, the sound quality was presented in the signal-to-noise ratio, which was the average power of signal divided by average power of the background noise. The fish sound database was a 3-Tier system and developed by PHP and MySQL. In order to reduce the storage size and maintain the integrity of data, the Relational Model was applied. Firstly, the recording data were conceptually represented as Entity-Relationship Diagram(ERD). Secondly, the ERD was transformed to relational schemas. Thirdly, the schemas was normalized by first, second, and third forms. To improve the users¡¦ efficiency the sound database provides three interfaces. One was data uploading, another was data searching according to the keyword of creature name, recording area, and recording time, the other was data comparing by recording number.

The objective of this thesis is to design a complete ITIL (IT Infrastructure Library) data model by using Entity-Relationship diagram and the argumentation of this model in relation to ITIL Configuration and Asset Management federative approach. The thesis is build of two major parts, where the first one focuses on the theory of recommendations and best practices in the IT Governance processes, its relationship to ITIL and a high-level overview of ITIL history. Theoretical part ends with the brief description of tools and methods used in data modeling. It is followed by practical part in which the content is based on analyzing of ITIL publications in the same order as IT Service Management life cycle phases and designing of the logical data model. Each chapter discusses at its end the abiliity of designed model to cover the data requirements for particular ITSM lifecycle phase. In the very last chapter, all partial models are joined into one complete data model and shown relations are argumented.

The objective of this dissertation is to suggest the structure of new IS in the company, to suit the recent data flows, and simultaneously to satisfy the needs of the user. According to the suggestions and concepts mentioned in the thesis, it should be possible to pre – set a completely functional IS.

This diploma thesis covers the design and implementation of changes and extension modules of a chosen information system, used in JUDr. Ján Bartánus's attorney office in Ružomberok. The system, implemented as a web application based on the Symfony framework, is dedicated to the simplyfing, monitoring and organization of the work processes in a generic attorney office located in the Slovak Republic. For the purposes of a correct design, the thesis contains an analysis of the current state of the given attorney office, the environment in which it operates, its information system and existing solutions. Tools that were used to conduct the analysis were the SLEPT method, Porter's five forces, model 7S and SWOT matrix. Based on the results of the analyses, a change of the system has been designed, which entails an upgrade of the system, its user interface, integration of the register of companies of Slovak Republic and an extension module intended for the financial valuation of work performed by an attorney. The application has been developed utilizing the PHP and JavaScript programming language. The valuation module integrates the Google Maps API. The stability and speed of the system were tested by functional tests and profiling of the duration of HTTP requests. The main contribution of this thesis is the design and implementation of an extension of the information system, which can be used in any arbitrary attorney office situated in the Slovak Republic, and its practical application in the chosen company. This thesis builds on a previous thesis dedicated to the design and implementation of the information system, which is being extended in this diploma thesis.
