Resource Assessment, Load Estimates and Component SelectionThe critical system design parameters include power consumption by each of the system components,sensors, microcontrollers, DC-DC power converters, power management and control unit, batteryprotection and charge control subsystem, and the estimate overall system losses. On the other hand, inorder to optimum size the system and complain with design requirements in term of the system size,weight, life and operability proper and accurate solar and wind energy assessment in the designationWSN operation areas and regions are also critical and needed in the system design and configuration. a) b)Figure 3 a) Monthly averages

experiments, Froude and Reynolds number scaling isaddressed in detail, and considerable time is spent discussing laboratory safety, instrumentation,data acquisition systems, and uncertainty analysis. Students complete several homeworkassignments individually, and three standard projects, completed in teams, involving a)measurement of resistance on an underwater vehicle, b) measurement of resistance on a surfacevessel, and generation of open water curves on a propeller.Figure 3: Towing tank models used in ENH.

The initial design of this mounting method isshown in Figure 10a and is made up of three pieces. In this design, a stationary mounting bracketwould have been glued onto each wall and each interchangeable 3D printed test piece wouldinclude notches to snap into each end of the mounting bracket. As the design team developed aprototype for this initial
