We present a method for generating a three-dimensional underwater map that is created in low visibility conditions using a diver with a wrist mounted depth gauge as the digitizer. Although the original sampling method can be sparse and prone to error, by extracting the depth profile from the dive computer and applying fractal image interpolation al...

... other sides of the box was generated from the IFS fractal interpolation algorithm. The data from Figure 8 was then used to determine a threshold between the values of the different objects and the rock floor of the quarry. Using this threshold, the three dimensional isometric view from Figure 7 becomes the one shown in Figure 9. ...

... These peaks correspond to dominant sine and cosine terms occurring in the power spectrum. Once the FFT is generated, the power spectrum of the data is calculated, which is the sum of the squares of the real and imaginary terms in (6), and is then transformed into decibels (dB). ...
We simulate a notional Navy SEAL rebreather diver on an extended mission using Model Predictive Control (MPC) theory. A mathematical framework for enabling physiological HUMS (Health Usage Management Systems) is shown. A rebreather simulation is used to derive MPC baseline Data Models of diver status by converting the simulation first into differential equations and then into lookup tables (LUT). When abnormal readings are indicated, sensor data from the diver is published to the ad hoc network, enabling intermittent upload. Mission success confidence is updated and determined during the mission. A novel method of converting MPC Data Models into lookup tables worn by the diver is given.
