For this study, we designed a QR Code Identity Tag system to integrate into the Turkish healthcare system. This system provides QR code-based medical identification alerts and an in-hospital patient identification system. Every member of the medical system is assigned a unique QR Code Tag; to facilitate medical identification alerts, the QR Code Identity Tag can be worn as a bracelet or necklace or carried as an ID card. Patients must always possess the QR Code Identity bracelets within hospital grounds. These QR code bracelets link to the QR Code Identity website, where detailed information is stored; a smartphone or standalone QR code scanner can be used to scan the code. The design of this system allows authorized personnel (e.g., paramedics, firefighters, or police) to access more detailed patient information than the average smartphone user: emergency service professionals are authorized to access patient medical histories to improve the accuracy of medical treatment. In Istanbul, we tested the self-designed system with 174 participants. To analyze the QR Code Identity Tag system’s usability, the participants completed the System Usability Scale questionnaire after using the system.

We proposed a QR Code Fabric Tag system, which provides an online archive for the textile companies to keep detailed information about the fabrics and transactions related to them. To provide easy way to access this information, each fabric cartel used by the company should be labeled with a unique QR code label. When the QR code is scanned by a QR Code Fabric Tag mobile application, installed on a company smartphone, all the information related to the fabric will be displayed. We tested the developed system on a group of 60 volunteers, and evaluated the performance of the system using the System Usability Scale questionnaire, filled by each participant.

Issues involved in mutual exclusion and background of mutual exclusion are discussed. A Ricart and Agrawala mutual exclusion algorithm is investigated. Simulation model of the system based on Petri Nets is described. Simulation results are presented and evaluated
