Educationcharacteristics of DUT are then measured before probe tips are manually moved to the nextDUT. The probe is moved manually to make connections and to measure properties of DUT.This requires a lot of human time as the user has to peer through the microscope while trying tofiddle with the dials and knobs on micropositioner to move the probe arm so the it can be placedat the desired location. The automation of micropositioners of the probe arm has allowed a greatincrease in the efficiency of the test procedures. Figure 1. Singatone H150 probe station modified with automated probes.

In most thermodynamics textbooks [1-9] it is assumed thatspecific volume, specific internal energy, and specific entropy of fluids in the compressed liquidregion are functions of temperature only and pressure effects are negligible.

In aircraft design, a process is executed such that all thedisciplinary studies of aeronautics are applied to produce together one single concept fora vehicle to be built followed by more detailed planning phases. The design is first of allachieved by creating a conceptual shape of the aircraft made by a convergence ofvariables that best fit the subjected mission requirements. The following seven steps givean overview of the conceptual design for an aircraft: 1) Analysis, 2) Integration, 3)Iteration, 4) Convergence, 5) Solution Space Screening, 6) Solution
