Monitoring system for applications and system of linux servers
Janovský, Martin ; Chmelař, Milan (referee) ; Janovič, Filip (advisor)
Bachelor's thesis solve the problem sight above distant Linux's servers. She describes technology, that are used for following servers. Further is described application by herself. Main problem at distant sight is, that the oneself have to check every one server separately. This performs central server provided by web server with the support language PHP and database MySQL. Central server creates interface between user and servers. All application is built on PHP, MySQL and SOAP messages. Server, which is monitored, is equipped web server and application for automatic execute process. All application is then built on exchange SOAP messages, which contain monitoring information. These data are preserved in database and further used for various statistics and graphs. By the help of web interface on central server can be information suitable displayed. This interface makes it possible to do action above single processes. Restarted or stopping process is at distant management used frequently. Naturally is respect emphasis on safeness. Optimal place for placement these application is operator centre or administrator's computer. Demand user has then displayed all monitored servers on monitor. On nonstandard state of process user is promptly alert. This situation he can promptly solve.

Design and implementation of signal processing library using Android
Janovský, Martin ; Hudec, Antonín (referee) ; Trzos, Michal (advisor)
The diploma thesis solves the problem of design and implementation of library for digital signal processing on Android platform. It describes problems with development software on this platform. There is also a debate about portion of Android on market. It describes technologies and ways, that were used for developing an application. It also explains the efficient programming techniques, in some cases, offering alternative solutions and ways. Effectiveness examines from the perspective of processing power and memory consumption. Continues through analysis Android platform architecture, and some features of its system to the description of some of its parts. Gets up to the description of work with the audio data formats, or to work with files and various collections of data. Then description continues with functions and the application itself. The actual library is controlled through the user interface and some other functions. User select parameters of each signal to be processed. The signal can be generated or the recorded sound signal. After selecting the parameters of each filter, the user can play the output signal and observe the change. In other part different instruments are compared and discussed some improvements, which accelerate and improve the entire application. The conclusion summarizes the results and benefits of the entire diploma thesis.

Selection of a suitable ERP system through methods of multi-criterion decision-making
Janovský, Martin ; Kuncová, Martina (advisor) ; Berková, Kateřina (referee)
My thesis is intent on selection and recommendation of a suitable ERP system for the distribution company distributing tea and coffee products in the Czech market. To select a suitable system, I used methods of multi-criterion decision-making, concretely the ORESTE, WSA, TOPSIS and MAPPAC methods. In the theoretical part of my thesis, I describe the methods of multi-criterion decision-making and principles of utilization the ERP systems. The practical part of my thesis is divided in hard-selection and soft-selection. The aim of the hard-selection lies in reduction of the total number of ERP systems (upon available public information) which then shall be the subject to making the final selection. The soft-selection is then applied to the adjusted list of systems. Within the soft-selection, I included the applied procedure as well as reasons for selection of appropriate criterions since they essentially affect the calculation. At the end of my thesis, I show the procedure of implementation the ERP system.

Watering garden problem
Janovský, Martin ; Kalčevová, Jana (advisor) ; Mynařík, Petr (referee)
Watering garden problem is focused on using a special methods of linear programming on real garden. Especially using of travelling salesman problem and vehicle routing problem. Practices of these methods are demonstrated on real garden. The problem comes when it's necessary to find an optimal path between source of water and plants needing some water. Both problems (travelling salesman problem and vehicle routing problem) are solved through optimization software and heuristic methods (method of the nearest neighbour, savings method and method of the cheapest input). Main goal is to find the best solution which is usable.
