A method for controlling paper making includes monitoring (302) a surface level of a fibrous suspension in a storage, and identifying (303) that the surface level has decreased so that at least one emptying criterion is met and thereafter identifying that the surface level has increased so that at least one refilling criterion is met, and responsively to the identifying that the surface level has increased so that the at least one refilling criterion is met, starting to dose a biocide agent into the fibrous suspension entering the storage. A corresponding apparatus and computer program are disclosed.

A method for monitoring hydrophobic particles contained in a pulp suspension, includes obtaining a sample from a pulp suspension or a filtrate of the pulp suspension. A fluorescent dye is added to the sample to stain particles in the sample. The sample is fractionated to obtain at least a first fraction and a second fraction, wherein the second fraction is a fiber fraction. The method includes for the obtained fractions, fluorescence emitted by the particles in the fractions, calculating an integral of the fluorescence measured for the fractions excluding the fiber fraction, and correlating the calculated integral of the fluorescence to the amount of acetone soluble material in the pulp suspension, and optionally measuring light scattering signal of the particles in at least first and second fractions.

Methods and systems for controlling robotic actions for agricultural tasks are disclosed which use a spacing-aware plant detection model. A disclosed method, in which all steps are computer-implemented, includes receiving, using an imager moving along a crop row, at least one image of at least a portion of the crop row. The method also includes using the at least one image, a plant detection model, and an average inter-crop spacing for the crop row to generate an output from the plant detection model. The plant detection model is spacing aware in that the output of the plant detection model is altered or overridden based on the average inter-crop spacing. The method also includes outputting a control signal for the robotic action based on the output from the biased plant detection model. The method also includes conducting the robotic action for the agricultural task in response to the control signal.

An apparatus for producing tubes comprises a mandrel, a winding unit, and a fluid dispensing unit. The tube is formed as the winding unit winds at least one strip of web material around the mandrel and advances the tube along the mandrel toward a distal end of the mandrel. The fluid dispensing unit is disposed at the distal end of the mandrel and is configured to dispense a fluid to the inner surface of the tube as it advances past the distal end of the mandrel.

A method, system, and computer program product are described capable of controlling an industrial based chemical process through accessing sensor data, pre-processing accessed sensor data through an automated process, forming an initial prediction model of the chemical process, and automatically determining linearity or non-linearity of the initial prediction model. As a function of quantitatively measured linearity, being non-linear, quasilinear, or linear, automatically train the initial prediction model, then deploy the trained prediction model in a manner that controls the subject chemical process at the industrial plant, including optimizing consumption of a certain resource. Data-driven modeling of non-linear, continuous-like industrial or chemical processes results.
