A system and method model a time series from missing data by imputing missing values, denoising measured but noisy values, and forecasting future values of a single time series. A time series of potentially noisy, partially-measured values of a physical process is represented as a non-overlapping matrix. For several classes of common model functions, it can be proved that the resulting matrix has a low rank or approximately low rank, allowing a matrix estimation technique, for example singular value thresholding, to be efficiently applied. Applying such a technique produces a mean matrix that estimates latent values, of the physical process at times or intervals corresponding to measurements, with less error than previously known methods. These latent values have been denoised (if noisy) and imputed (if missing). Linear regression of the estimated latent values permits forecasting with an error that decreases as more measurements are made.

A device for determining the relative heights between two points in direction gravity acts and inclination sensor for single- or multi-axis determination of an inclination relative to the vertical direction defined by the gravitational field. The device can include: a connecting hose filled with a liquid; a first and a second pressure sensor arranged at opposite ends of the hose; a processor to determine a relative height between a first reference point with a fixed positional relationship to the first pressure sensor and a second reference point with a fixed positional relationship to the second pressure sensor; a synchronizer; a respective wireless module at each of the hose. The synchronizer can synchronize a first time point with a second measurement time point, wherein the processor is configured to assign the measured hydrostatic pressures to the same, common measurement time point on the basis of the synchronized measurement time points.
