The application provides a method for improving nutrient supply of female floral branches of Populus deltoides artificial hybridization. According to the technical links of the hybridization operation, the method separately integrates and improves the cultivation of female floral branch nutrient-supply seedlings (i.e., grafting rootstocks of floral branches), the pre-management of female floral branch nutrient-supply seedlings, the hydroponic management of floral branches, the Marching between female floral branches and rootstocks, the management of female floral branch nutrient-supply seedlings and the hydroponic management of female floral branches, so the goal of improving the seed-setting rate and quality of poplar hybrid seeds which came from the floral branches cultured in water has been achieved. Compared with the conventional method, the method of the invention not only can realize good seed quality, but also improve the seed-setting rate, and has a remarkable effect when applied to Populus deltoides artificial hybridization.

According to an aspect, there is provided a method and system for predicting a forest stand target attribute. The solution uses direct indicator data about forest stands, indirect indicator data about the forest stands and empirical measurement data about the forest stands to build a trained model for a forest stand target attribute. Using the trained model, it is possible to predict, for a given forest stand, the value of the forest stand target attribute.

This invention relates to off-road work machines and to unloading an off-road work machine and particularly to an arrangement and a method for controlling the unloading of a forestry machine. It is characteristic of a method according to the invention for controlling unloading of a forestry machine (10), in which the forestry machine (10) comprises a load space (11) for a timber load (22), a boom structure (12) and a wood-handling tool (16) attached to said boom structure, that the method comprises the steps of: defining and noting down (43), (44) the location (20) of the timber pile, calculating and noting down the location of the edge of the timber pile, picking (45) a timber bundle from the timber load (22) by the wood-handling tool (16), calculating (46) the distance of the end justified on a load screen (13) of the edge of said timber bundle from the wood-handling tool (16), calculating an unloading location for said timber bundle in the defined location (20) of the timber pile, and controlling and unloading (47) said timber bundle into the timber pile in the said calculated unloading location such that one edge of the timber pile becomes even and straight.

Systems and methods are provided for imposing physical actions, by endpoints, based on activities by users. One such method includes imposing a physical actions via a drone, by an endpoint associated with the drone, based on an activity undertaken by a user. The method includes receiving, by a computing device, an activity message including data indicative of an activity of a user and retrieving at least on rule from a data structure based on the data indicative of the activity where the at least one rule includes a physical action for said activity of the user. The method then includes identifying, by the computing device, the physical action from the at least one rule and transmitting, by the computing device, an order for the physical action to an endpoint, whereby the endpoint commands a drone to perform the physical action.

A feed roller assembly of a harvester head of a forestry machine includes a pivoted arm operated by a hydraulic cylinder and a feed roller and one operating device attached to the pivoted arm having an attachment hub driving the feed roller, the feed roller includes at least one attachment flange, at least two toothed discs, spacer pieces between at least the attachment flange and the toothed discs, attachment bolts connecting the attachment flange, the toothed discs, and the spacer pieces to form the feed roller as a bolted construction, and a cleaning comb attached to the arm for cleaning gaps formed between each pair of components when the feed roller is rotating.

This invention relates to off-road work machines and to controlling the brakes of an off-road work machine and particularly to an arrangement and a method for controlling the working brakes of a hydraulic or electric work machine. It is characteristic of a method according to the invention for controlling the brakes, preferably the working brakes, of a hydraulic or electric work machine (10), (50), in which the hydraulic or electric work machine (10), (50) comprises one or more frame parts (11), (12), (51), (52) and a moving means (13), (53) that the method comprises the steps of: detecting (31), (41) a driver's control action for starting the motion of the hydraulic or electric work machine (10), (50), keeping (32), (42) the brakes of the hydraulic or electric work machine (10), (50) applied and releasing (35), (45) the brakes of the hydraulic or electric work machine (10), (50) when said measured (33), (43) torque value exceeds a predetermined calculatory torque value.

A forestry machine includes a ground propulsion apparatus, a chassis supported by the ground propulsion apparatus, a cab, an engine and a work implement. The chassis includes a front chassis portion and a rear chassis portion. The front chassis portion includes an upper portion and a lower portion. The rear chassis portion has a wood basket supported thereon. The cab is rotatably supported on the front chassis portion by a rotatable connection about a cab rotation axis to be selectively rotated 360 degrees. The engine is integrated into the front chassis portion. At least a part of the engine is disposed below an upper most surface of the upper portion. The work implement is movably attached to the cab. The work implement includes a boom movably attached to the cab, an arm movably attached to the boom, and a work tool attached to the arm.

Systems and methods are provided for imposing physical actions, by endpoints, based on activities by users. One such method includes storing multiple rules in a data structure, where each of the multiple rules indicates a physical action to be performed in response to an activity, and then receiving, by a computing device, an activity message including data indicative of an activity of a user. The method also includes retrieving, by the computing device, one of the multiple rules from the data structure based on the data indicative of the activity and identifying, by the computing device, the physical action included in the one of the multiple rules. The method then includes transmitting, by the computing device, an order for the identified physical action to an endpoint, whereby the endpoint commands a drone to perform the identified physical action as a response to the activity of the user.
