Independent predictors of prognosis in patients after out-of-hospital cardiac arrest
Kroupa, Josef ; Moťovská, Zuzana (advisor) ; Ošťádal, Petr (referee) ; Duška, František (referee)
The dissertation refers to the up to date topic of Out-of-Hospital Cardiac Arrest (OHCA). The clinical research is divided into two parts. 1. Characteristics and Survival Determinants in Patients After Out-of-Hospital Cardiac Arrest in The Era of 24/7 Coronary Intervention Facilities Background. Survival rates and outcomes after out-of-hospital cardiac arrest (OHCA) remain low despite investments of time and money. The goal of this analysis was to identify variables related to survival of patients transferred to our coronary care unit (CCU) after an OHCA. Methods. 102 consecutive OHCA patients, mean age 64.6 (SD 13.3), 70.6 % men, between January, 2011 and December, 2013, who were transferred to our tertiary care CCU, were studied. Results. Cardiac-cause OHCA was present in 84 patients (82.4 %). Of these 60.7 % had an acute coronary syndrome (ACS) - STEMI 35.7 %; NSTEMI 23.8 %. Coronary angiography was performed in 73 (71.6 %) patients - 81.0 % with cardiac- and 31.3 % (5/16) with a non-cardiac cause. Percutaneous coronary intervention (PCI) was performed in 50 patients (68.5 %), 49 with cardiac-cause, and succeeded in 92.0 %. In-hospital mortality was 38.2 %, one-year mortality was 51.5 %. In-hospital and one-year mortality were related to age (p = 0.002 resp. p = 0.001), first ECG rhythm (p =...

Machine vision implementation in the UVSSR PORTABLE CELL production system
Gómez Rojas, José Luis ; Kroupa, Jiří (referee) ; Bražina, Jakub (advisor)
This thesis investigates the integration of computer vision into Industry 4.0, utilizing the UVSSR CELL at Brno University of Technology. Focused on enhancing virtual commissioning, it introduces three innovative vision techniques linked via an OPC server to an IoT gateway. Object recognition, hand gesture control, and facial recognition are employed, improving robotic arm operations and security protocols. This integration resulted in high accuracy trained model for object detection with mAP50-90 close to 0.9, and control precision of the technologies and the virtual environment, contributing significantly to smart industry automation and setting a call for future work on top of it. The thesis covers methodology, technological implementation, and prospects for advanced, efficient machine vision systems within industry 4.0.

Software solution for storing data from robotic 3D printing
Žalud, Štěpán ; Kroupa, Jiří (referee) ; Bražina, Jakub (advisor)
This thesis deals with the design of a software solution for storing data from robotic 3D printing. The assignment is based on problems observed in the Voxell company. The theoretical part presents the issue and puts it in context within modern industry. Additionally, it introduces tools used for creating such services at a basic level. This is followed by a system analysis leading to the design of the solution's architecture. The practical part then discusses the selection of the database, the creation of individual services, and the deployment of the application on the Docker platform. Finally, the work is evaluated and a possible future direction of development is outlined.
