A memory cell including magnetic materials and heating materials, and methods of programming the memory cell are provided. Reflection may be used to build the table of those relationships so that changes to the relationships between those three layers can be easily and quickly made without impacting higher levels in the software stack. Each strain gauge is arranged parallel to the longitudinal axis A-A of the axles to measure the strain exerted on each axle in a direction substantially parallel to the longitudinal axis A-A of each axle. The other, lower flow rate, section of the tank may be positioned so that it has a cooler temperature and thus serves to increase the efficiency of the heat exchange by extracting extra heat energy out of the cooled fluid before it leaves the tank. The intermediate section and the elastic member may provide for variable resistance during movement of the upper and lower sections.
