| Crop yield may be assessed and predicted using a piecewise linear regression method with break point and various weather and agricultural parameters, such as NDVI, surface parameters (soil moisture and surface temperature) and rainfall data. These parameters may help aid in estimating and predicting crop conditions. The overall crop production environment can include inherent sources of heterogeneity and their nonlinear behavior. A non-linear multivariate optimization method may be used to derive an empirical crop yield prediction equation. Quasi-Newton method may be used in optimization for minimizing inconsistencies and errors in yield prediction. Minimization of least square loss function through iterative convergence of pre-defined empirical equation can be based on piecewise linear regression method with break point. This non-linear method can achieve acceptable lower residual values with predicted values very close to the observed values. The present invention can be modified and tailored for different crops worldwide. | ||||||

| A system for fluid processing is provided to control shear, point velocity and pressure in either a Newtonian or non-Newtonian fluid which includes creation of three fields, namely a dynamic microshear field, a dynamic velocity field and a dynamic pressure field, with the fields being created by the injection of energy between 1 KHz and 10 MHz into the fluid. Control is achieved by control of the angle at which mechanical energy is delivered, steering and/or focusing of the energy, control of the amplitude of the energy waveform, of the energy, and control of the frequency of the energy in one embodiment to eliminate standing waves. By controlling the three fields, the system is able to control overall fluid behavior. In one embodiment, energy is injected into a fluid at any angle to the direction of flow assuming the fluid is flowing, with the injected energy providing a predetermined controllable zone of energy in the fluid at the region of energy injection. In another embodiment, the container itself is a transducer that acts as a processor, where the energy comes from the container itself. In a further embodiment, a phased array is used for electronically steering and focusing energy to any point within the fluid volume to provide for the desired shear, velocity and pressure distributions. Note that the direction and focusing of the injection of energy is turnable by physically moving a transducer or by the use of a phased array. | ||||||
| 103 | INCLINED TUBULAR SEPARATOR FOR SEPARATING OIL WELL SUBSTANCES | EP13814938.0 | 2013-12-20 | EP2934714A1 | 2015-10-28 | SKOVHOLT, Otto |
| The present invention relates to a tubular oil separator providing separation of respective fluid components mixed in fluids from oil wells, wherein the tubular oil separator is arranged to mitigate problems related to turbulence and possible non-Newtonian fluid behaviors of fluid components mixed in the fluids from the oil wells in the oil separator. The invention further relates to a method of operating a separator. Moreover the invention relates to a system of multiple separators. Inventive aspects of the separator comprises an elongated outer, closed tubular section and an elongated, inner tubular section, which is closed in one end and open in another end, - where the inner tubular section is arranged inside the outer tubular section, - and where oil well substances are introduced into the open end of the inner tubular section via a tube feed section passing through the outer tubular section and into the inner tubular section, - and where the inner tubular section comprises multiple, elongated and parallel slots arranged in a longitudinal direction of the inner tubular section in a circumferential manner, - where the inclination of the separator facilitates separation of the oil well substances into lower density substances and higher density substances, - where the lower density substances by buoyancy drift upward through the slots and exit via an upper outlet in the outer tubular section and higher density substances sink downward through the slots and by gravitation exit via a lower outlet in the outer tubular section. | ||||||

| The present invention relates to a method of adapting and manufacturing a separator system comprising multiple inclined separators for separation of respective substances or substances mixed in fluids from oil wells and adapting the separator system to a change in the substance or use with another oil well. The method involves determining percentage fraction of respective fluid phases in an oil from a specific oil well and at a specific time and estimating expected production rate from the specific oil well at a specific time to estimate the streaming capacity of each respective fluid phase through separators of the separator system. The method also involves arranging a plurality of interconnecting frameworks of pipes in parallel or serial depending on the estimate streaming capacity. | ||||||
