Awarded a Master's Degree with Honours

On November 15, 2023, at the Department of Electromechanical Engineering at the University of Technology, Maisa Asaad Salman presented and defended her dissertation to get a master's degree. The thesis, titled "Design and Development of a Thermoelectric Cooling System for Special Medical Applications," aimed to design a device for storing multiple medical materials at appropriate storage temperatures gradually for a relatively long time. The design is based on the World Health Organisation's (WHO) storage guidelines.

The previous designs were incubators for a specific type of material with a particular storage temperature. The new system operates on a DC power source with a new control for the device's operation. The system also used the Internet of Things (IoT) technology for remote monitoring by an Android mobile phone program. The program activates the 8266Wi-Fi ESP module with Node Mcu to connect the device to the network and make it remotely accessible.

Testing and evaluating the outcomes of various cases served to evaluate the work. The researcher tried to determine the effect of the number of thermoelectric modules on thermal performance and reaching the appropriate storage temperature. She also investigated the possibility of reducing power consumption in three different cases.

The researcher found that reaching 3 degrees Celsius inside the incubator is possible, which may be suitable for storing many medical materials. They also analysed the results using a storage box and studied their temperature distribution using the ANSYS software.

The thesis defence committee consisted of:

Associate Professor Ali Hussein Noaman, Chair
Associate Professor Seham Ahmed Hashim, Member
Associate Professor Amjad Talal Saeed, Member
Associate Professor Mahmoud Mustafa Mahdi, Member and Supervisor
Assistant Professor Magda Khalil Ahmed, Member and Supervisor

The thesis defence voted to award the Master's Degree of Science to the student with honours.
