Quality management in company
FROULA, Stanislav
The thesis deals with the analysis of quality management system in a selected organization and with tasks assigned by the organization's quality manager. The company is Aspera, spol. s r.o., specifically its metal manufacturing centre Aspera Technology in České Budějovice. The thesis is divided into a theoretical and a practical part. The theoretical part is based on study of scientific literature and focuses on quality definition, history of quality management, quality management system principles and concepts and quality management tools, especially process flowchart, Pareto diagram and FMEA. The practical part describes the company, its manufacturing centre and its quality management system. The next part deals with the three assigned tasks. First, designated company processes are described and visualized in the form of flowcharts. Second, weak points and risks of these processes are analysed using FMEA and corrective actions are recommended. Third, the most significant internal defects are identified using Pareto chart and cost analysis. At the end of the thesis some suggestions for improvement are provided. The suggestions were observed during an internship in the company and should enhance the quality management system and help the overall operation of the company processes.
RSA Algorithm and Its Use in Electronic Communication with State Authorities
FROULA, Stanislav
This bachelor thesis focuses on the RSA algorithm and it's use in electronic communication. The RSA algorithm is curently one of the most widely used asymmetric encryption algorithms. It was first publicly described in 1977 by the mathematicians Ron Rivest, Adi Shamir, and Leonard Adleman. It's the first algorithm that is suitable for both electronic signature and public key encryption. The theoretical part explains all related concepts of cryptography. The basic operating principle of the algorithm is described in specific simplified example. It also includes a description of public key encryption and a list of institutions, which use digital signature to verify authenticity of the sender. The practical part focuses on a questionnaire survey, which investigates the awareness level of internet banking users in term of security of using internet banking and following the security policy recommended by banks. The results are analysed and evaluated at the end of the thesis.
