Topic 1 – Medical Care Task Scheduling

Implementation of an ECG algorithm utilizing a Microcontroller and a set of sensors. 

The objective of this Thesis is to determine the capabilities of a scheduling algorithm in the medical field. As there are several items to be considered, including criticality of the tasks, energy available and human conditions, it is important to analyze the timely and correct execution of the system. 

We are looking for a responsible and proactive student who is willing to work, according to its experience level (Bachelor / Master), on an embedded System: M5Stack programmed with C/C++  

Topic 2 – Scheduler Analysis

Analysis of Parameters for a Scheduling Algorithm 

We are performing some tests in the scheduling area and developed a dynamic scheduling algorithm which could be used for a variety of scenarios. The problem is that we require the fine tuning of the parameters present in the algorithm.  

The student (Bachelor/Master) will learn about scheduling algorithms, optimization and parameter selection over different techniques. The algorithm and test environment were created using C/C++, Matlab and FreeRTOS 

Topic 3 – Energy Testing and Battery Analysis for a Multi-Criticality Scenario

Analysis of energy consumption and battery life in a multi-criticality tasks scenario 

Our approach on a novel scheduler has proven to be energy efficient, however, we need to obtain more information to be sure that the low energy consumption is applicable on a variety of use cases. Therefore, it is necessary to identify, define, test and analyze the energy consumption in different configurations 

The student (Bachelor, Master) should be interested in the study of energy consumption, furthermore, knowledge in C/C++ are beneficial
