Abstract: Panel for floating cultivation of plants on water, includes parallel grooves at a top side extending longitudinally, adapted for receiving a substrate and a number of plants or precursors in the substrate, each groove extending through the panel from a first top plane to a second parallel plane. The panel includes air chambers at a lower side extending substantially below the second plane, each of the air chambers allowing therein formation of air roots of plants supported in the substrate of the grooves. At the second plane, each groove is spaced apart from the circumferential side wall of the air chamber it debouches in when projected onto a plane normal to the longitudinal direction, each of the grooves including at least two side support surfaces extending parallel to the groove and below the top side, the side support surfaces adapted for substantially completely supporting the substrate in the groove.

Abstract: A vehicle capable of being converted between a flying condition and an automotive riding condition. The vehicle has a telescopically extendable tail having a first tubular tail segment and a second tail segment disposed axially slideable within the first tubular tail segment. The tail is provided with at least two form-closing coupling members located at an axial distance from each other for providing a force-transferring coupling between the second tail segment and the first tubular tail segment in the extended state of the second tail segment, each of the form-closing coupling members capable of transferring torque and transverse forces, and each of the form-closing coupling members coming into engagement by axial displacement of the second tail segment in the outward direction.

Abstract: A method of decomposing an image or video into a plurality of components. The method comprises: obtaining (10) an intensity signal of the image or video; and decomposing (30) the intensity signal into a component representing the three-dimensional structure shape of one or more objects in the scene and at least one other component. Also provided is a method of performing an Empirical Mode Decomposition on data in two or more dimensions, using normalized convolution.

Abstract: The present invention discloses a vehicle (1) capable of being converted between a flying condition and an automotive riding condition. The vehicle has a telescopically extendable tail (10) comprising a first tubular tail segment (11) and a second tail segment (12) disposed axially slideable within the first tubular tail segment. The tail is provided with at least two form-closing coupling members (21, 35; 31, 36) located at an axial distance (LI) from each other for providing a force-transferring coupling between the second tail segment (12) and the first tubular tail segment (11) in the extended state of the second tail segment (12), each of said form-closing coupling members (21, 35; 31, 36) capable of transferring torque and transverse forces, and each of said form-closing coupling members (21, 35; 31, 36) coming into engagement by axial displacement of the second tail segment (12) in the outward direction.

Abstract: A method and apparatus for measuring the amount of mire and mud in a suction dredge hopper 2, which mire and mud is a constituent of a fluidized mixture. An acoustic level gauge 16 measured the position of the upper surface 3 of the mixture and a plumb weight 7 measures the position of the lower limit of the mixture defined by the top of a sand layer 4. A plurality of differential pressure responsive density measuring devices P measure the density of mire at different levels. From these measured valves the total amount of mud and mire is determined.

Abstract: Dredge with drag pipe, consisting of a number of pipe sections interconnected by hinged joints, whereby drag lines are connected to said hinged joints and to the front and rear end of the drag pipe and furthermore the rotatably supported front end of the drag pipe is guided into vertical guiding elements at the side wall of the ship and the rear end carries the drag head. The dredge contains for each drag line a separate winch, controlled by an electronic control unit for automatically moving the drag pipe outboard, lowering the rising the drag pipe and moving the drag pipe inboard. During the whole dredge operation from the outboard movement of the drag pipe unitl the inboard movement thereof the unwound drag line length of each winch is measured, whereby the electronic control unit determines based on said measured drag line length at each moment the position of the drag pipe.

Abstract: A method for controlling the operation of a dredging apparatus provided with a cutting tool according to changes in at least one parameter such as soil resistance, comprises performing a working stroke with the cutting tool, measuring that parameter during that one stroke, recording the measured parameter as a function of the distance covered during that one working stroke, and regulating the hauling speed during the following working stroke according to that function. In this way, maximum permissible hauling speed can be achieved without overloading.
