Main Challenge/Objective- (English)§  The mathematical background of plant-related integer order models (Hayden, simplified Hayden, double shell, lumped, Garut Citrus) models have been summarized as well as the single/double dispersion models.
§  Extract the best circuit parameters circuit for the Cole-Cole model that fits the experimental results via different optimization techniques from a mathematical point of view to choose the best performance versus the complexity of the used algorithms. Also, aging effect of apples for different types of apples (red, green, yellow).
§  Design a wireless module to measure the bio-impedance and submit these results automatically to the desktop. This module has been used to monitor the growth rate of strawberry days and nights showing the effect of photosynthesis effect.
§  Compare between the fitting parameters for different optimization algorithms of different bio-impedance magnitude only measurements compared with total impedance measurements, where the single dispersion Cole-Cole model is employed based on the outcomes of the last report. 
§  Discuss in detail the procedure of designing 30 prototypes, including the explanation of firmware flowchart and the whole design process, starting from schematic to PCB, each component in the prototype is discussed.
