摘要： The invention is directed towards a method and system for optically-based monitoring of chemicals of potential concern (COPCs), including mercury (Hg), methyl mercury (MeHg), and polychlorinated biphenyls (PCBs). It employs a multi-parameter statistical analysis model, such as partial least square regression (PLS regression), to identify combinations of predictors (e.g., optical, water quality, and physical properties) that have large covariance with the response values. The predictive model is validated against analytic samples from laboratories. The steps in the method are repeated until predictors, or parameters are selected that avoid over-fitting and which yield physically-based results.

摘要： Embodiments are directed towards a wave measuring electronics device that is integrated within a buoy and the buoy is moored in an ocean. The wave measurement device performs a computer-implemented method for estimating wave motion, including receiving 3D sensor data from each of an accelerometer and a gyroscope, determining, an absolute orientation of the buoy based on said 3D sensor data; and estimating, the true earth acceleration of the buoy over a specified time interval.
