This thesis deals with the issue of the project management, project portfolio management and environment settings for the management and portfolio analysis in a fictional organization. In the theoretical introduction there is outlined the situation of the education of the project portfolio management at universities in the Czech Republic, Europe and worldwide, in summary form of founded courses that deal with this issue. Some basic principles of PMI methodology follow to introduce the reader to the project and portfolio management. As a practical part of this thesis there has been project management solution software implemented as a support for the portfolio management education. Microsoft Project 2010 has been selected for this purpose. This part of the thesis guides reader through practical topics like how to set up the whole environment including all utilities and contains a description of services settings. As example there were also sample roles and resources of the company set up, which were subsequently assigned to fictional projects so that the business portfolio analysis based on set of business goals and prioritization of individual projects could have been performed. The contribution of this work can be found mainly in the possibility of portfolio management education and training by using one of the leading software tool that are successfully implemented in a real production environment, and to try out the various acts and practices and also to clarify the various processes in the context of specific projects within the portfolio. Prepared fictional organization and sample data can be especially used as a model for handling various assignments in the upcoming educational courses at VŠE.

Thesis Price models and SLA for shared services of data centers has as objective to establish best practice, so-called "best practices" of SLA and price models for data center services. Work is divided into two parts, theoretical and practical part. The theoretical section is wants to familiarize the reader with the basic concepts such as outsourcing, reasons and risks of use. I describe the base models for providing IT services as well as pricing models for services as described in the literature. I will focus on data centers and TIER standard categorization, too. The practical part is based on an analysis of information that I got from an interview with the experts working for the biggest data center companies in the Czech Republic. Based on this information, I tried to compile the best practices for creating pricing models for data center services that are actually used in practice. Specifically, the server housing, server hosting and virtual server services. Also, for these services create an SLA that can be used by some data center company in the Czech Republic.

Context. During the usage of a product, evaluating its performance quality is a crucial procedure. Web servers are one of the most used technological products in today’s modern world[1]. Thus, in this thesis we will evaluate and compare the performances of two web servers. The servers that are tested in the experiment are a raspberry pi 3B and a personal HP laptop. Objectives. The main objective of the study is to evaluate the performance of a raspberry pi 3B as a web server. In order to give a clearer image of how the raspberry pi performs, the laptop will also be evaluated and its performance will be used as a contrast during the study. Realization. To fulfill our objective, an experiment was conducted with the help of a performance testing tool called apache bench. To provide comprehensive performance results, the served content and the server software were altered throughout the experiment. The number of simulated users sending the requests were also altered. Results. The results were gathered by sending more than 1000 HTTP-requests to the two servers that served static and dynamic websites. The number of served requests per second and the CPU consumption of the servers were the recorded results. The raspberry pi exhibited response times as high as 1164 requests per second and CPU consumption that varied between ≈6% and ≈40%. In comparison to the laptop, on one occasion it exhibited a better processor utilization serving HTTPrequests of one user. Conclusions. Regardless of the used server software, although the laptop was slightly performing better, the raspberry pi had a closer response time in comparison to the laptop when both of them were serving a static website. On the contrary, when both were serving dynamic content the raspberry pi had a very low response time in the comparison. Out of the two used server software, nginx gave it a better CPU consumption in contrast to the laptop that had a better processor. That is irrespective of the served content type.

The theme of this diploma thesis is operating system OS X Server services by Apple. The thesis presents the possibility of their use for data sharing and communication among users of computer networks and examines the practical use of the information society. The opening chapter is an introduction of OS X Server. The second chapter deals with the progression of the system, its features, hardware selection, system requirements, support and overall evaluation. The third chapter is devoted to server services and their protocols. The fourth chapter presents the basic tools needed for server management and data protection. The essence of the work consists of the practical part, which provides services server uses based on the case study of a musical recording studio 3bees. Part of this thesis is also Research of the OS X Server deployment in the Czech Republic, which was organised by questionnaire survey. The survey focuses on the analysis of the environment and conditions in which the product is deployed and the most frequently used services.

ITC/USA 2008 Conference Proceedings / The Forty-Fourth Annual International Telemetering Conference and Technical Exhibition / October 27-30, 2008 / Town and Country Resort & Convention Center, San Diego, California / With the growing interest in networked data acquisition there has been a lot of focus on networked data acquisition systems. However, the requirements of a flight test instrumentation system go beyond networked DAU's. For example, a FTI network fabric has particular requirements for switches, time grandmasters, recorders, data servers and network terminals to the ground. This paper discusses these components and how they inter-operate in a single, fully networked system and discusses some FTI oriented requirements for same. Where relevant, we discuss the results of some experiments with network latencies; packet losses etc. and discuss some enhancements that can contribute to improved efficiency for flight test programs.

The purpose of the investigation is to determine the most effective solution, which allows safe storing and transmitting of financial information in terms of execution speed, resistance to hacking and ease of implementation. Research object is subject area related to the transfer of encrypted financial information like: encryption algorithms, algorithm of hashing functions, algorithm of electronic digital signature. The result of research is the software implementation of the server and client for sending encrypted information. Also client could only encrypt/decrypt information. The main part of research is to find the most suitable algorithm for transfer of encrypted banking information. The solution has been implemented on the Java programming language in programming environment IntelliJ IDEA 8, using Java Cryptography Extension (JCE) for digital signature.

International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Visitors to web pages are, in most cases, restricted to viewing information the page designer has anticipated they will be interested in viewing. Many times this is adequate, but there are instances where the visitor wants the information they view to be based on selections they choose. The Air Force Research Laboratory (AFRL) Space Vehicles Directorate anticipates selected customers will have a need to view very large data sets that vary from the satellite payload to the satellite state of health1, and will require controlling what they view in an “ad hoc” manner. In response, AFRL is using Java Server Pages developed within the data center to bring interactive and dynamic web page content to these customers.

<p>Detta examensarbete beskriver dator- och nätverkssäkerhet. Syftet med detta examensarbete är att undersöka den interna nätverkssäkerheten på en gymnasieskola. Speciellt viktigt att undersöka är de kriterier skolan har, om kriterierna uppfylls och på vilket sätt dessa kan testas. Tester utfördes gällande säkerhetsprogramvaran för att säkerställa att den verkligen var säker mot intrång. Tester genomfördes även för att kontrollera att elevdatorerna hade ett BIOS-lösenord närvarande, att eleverna hade lagringsutrymme på servern men inte kunde överskrida lagringskvoten, och att eleverna var lokala administratörer på en bärbar klientdator. Ansvarig IT-tekniker på gymnasieskolan tillhandahöll information om hur nätverket var tänkt att se ut utifrån klientanvändarnas perspektiv. En experimentell metod användes för att fastställa om skolans interna nätverk var skyddat mot interna hot. Referenser från internet, såsom artiklar och databaser, har använts. Även böcker och muntlig kommunikation har använts som referenser. Efter vår analys av gymnasieskolans interna nätverkssäkerhet, konstateras att eleverna inte kan utföra otillåtna åtgärder inom det interna datornätverket som resultat av felkonfigurationer eller sårbarheter som har upptäckts av denna analys. En genomgång av den fysiska säkerheten gällande gymnasieskolans datornätverk och en genomgång av den externa säkerheten i nätverket föreslås.</p>
