Preparation and characterization of optical metasurfaces
Weiss, Vlastimil ; Čižmár, Tomáš (referee) ; Dvořák, Petr (advisor)
This thesis presents a comprehensive study on the preparation and characterization of dielectric optical metasurfaces. Optical metasurfaces, which are artificially structured surfaces, enable precise manipulation of electromagnetic waves at a subwavelength scale, surpassing conventional optics in terms of spatial resolution and the complexity of optical transformations. The work is conducted at the Institute of Physical Engineering, Brno University of Technology in colaboration with CEITEC, and involves the use of advanced techniques such as ion beam etching through masks created via electron beam lithography (EBL) and the deposition of optically active materials into EBL matrices. The primary objectives include a thorough literature review, the fabrication of dielectric metasurfaces based on phase control mechanisms, and the detailed morphological and optical characterization of the produced structures. The research employs digital holographic microscopy and confocal optical spectroscopy for optical characterization, as well as numerical and semi-analytical simulations. The results contribute to the ongoing development of high-efficiency optical components and highlight the potential applications of biophotonic devices in the field of nano-optics.

Web Services Security for a Service Consumer
Novotný, Petr ; Weiss, Petr (referee) ; Rychlý, Marek (advisor)
The objective of this project was to introduce to a reader different possibilities of a web security and its authentication. Another part of this project was to create a client application communicates with the web service. The client part should at the some time serve the web services developer for checking chosen web securities.

Analysis of Business Process Diagrams
Ludvík, Martin ; Květoňová, Šárka (referee) ; Weiss, Petr (advisor)
The aim of Analysis of Business Process Diagrams is to create procedure that is able to find typical patterns in business process diagrams. Besides, it is necessary to design and implement application, which will be able to find and mark selected workflow patterns. This analysis is based on XML document, in which a business process diagram is stored. Important thing is to keep the ability to extend the number of patterns, which can be find out in a diagram. Also, it is important to solve some special situations, i.e. overlapping of patterns.

Store Information System
Hezoučký, Ladislav ; Weiss, Petr (referee) ; Masopust, Tomáš (advisor)
This bachelor's thesis deals with store information system. The main goal of this thesis is to develop a functional information system which will provide to catch the substance of operations in the stock ( stock receipt and stock out, draw purchase orders, draw invoice ). The system is implemented by using programming languages HTML, PHP and JavaScript. Database MySQL was choosen as a data storage.

Interfaces of Web-Services
Kubát, David ; Rychlý, Marek (referee) ; Weiss, Petr (advisor)
The objective of this thesis was to get acquainted with the proposition of the service-oriented architecture and its real representation web services. To understand the principles of their functioning, creation, communication and the ways to finding and using them. To be specific, the goal of this project was to analyse a current program, design its transfer to the web service description language and to implement a web service interface layer upon this program. The system is demonstrating the basic principles of the web services and the function of the interface during the communication between its provider and customer.

Transformation of WWW Pages into Web Services
Klement, Jan ; Rychlý, Marek (referee) ; Weiss, Petr (advisor)
The objective of this thesis was to acquaint oneself with web applications, study their architecture and communication and compare using of web applications and web services. Web services enable mass data sending and partially automate web applications. The aim of the thesis was to design a transformation of WWW page into web service in general. Furthermore, an application providing the transformation was implemented.
