    Abstract: A flow distribution system for distributing and dividing the flows of at least two separate fluids, the distribution system comprising: a three-dimensional nested structure of at least two fluid transporting fractals comprising at least a first fluid transporting fractal and a second fluid transporting fractal, each fluid transporting fractal having a respective fluid inlet which bifurcates to a plurality of fluid outlets, each fluid transporting fractal being configured to facilitate a flow therethrough independent from a flow in the other fluid transporting fractal, each fluid transporting fractal extending along and about a central axis between fluid inlet and a plurality of fluid outlets; wherein each fluid transporting fractals comprises of a series of recursive bifurcation units assembled in a selected number of stages, each bifurcation unit comprising a Y-shaped bifurcated element which is fluidly connected to two successive bifurcation units, each successive bifurcation unit being rotated relative to the central axis by an angle of between 60 and 120 degrees relative to the previous stage; each fluid transporting fractal is intertwined with the other fluid transporting fractal; each fluid transporting fractal is positioned offset from the other fluid transporting fractal about the central axis and are arranged such that each fluid outlet from one of the fluid transporting fractals is located adjoining a fluid outlet of the other fluid transporting fractal, and each fluid transporting fractal is centered about a flow axis which is laterally inclined from greater than 0 to 20 degrees from the central axis and longitudinally inclined from greater than 0 to 20 degrees from the central axis.

    Abstract: A method for use in colourising a three-dimensional (3D) point cloud of an environment, the method including determining timing information indicative of a time of capture of a frame; identifying at least some 3D points of the point cloud in the frame based on the position of the camera and determining a local point cloud that captures a scene in the immediate vicinity of the camera, wherein a visibility check is performed on the local point cloud to determine points in the local point cloud that are visible from the perspective of the camera for a given frame; and determining a candidate colour for the at least some of the 3D points using a colour of a corresponding pixel in the frame extracted from the video data; and, assigning a colour to one or more points of the 3D point cloud using candidate colours obtained from multiple frames.

    Abstract: A method of injection of liquid or gaseous ammonia fuel into a reciprocating engine that includes at least two cylinders, each cylinder including a piston that moves reciprocally within that cylinder, each cylinder having a head location at one end located opposite to a compression end of the piston and defining a combustion chamber therebetween, the cylinder including at least one inlet valve through which combustion gases are fed into the combustion chamber and at least one exhaust valve through which spent combustion gases egress the combustion chamber, the piston moving the cylinder in a cycle between top dead center where the piston is located closest to the head location and bottom dead center where the piston is located furthest from the head location, and including at least one fuel injector located at or in the head location, and wherein the method comprises: injecting the ammonia fuel into the combustion chamber of each cylinder as at least one fuel jet with a timing of: after the at least one exhaust valve of the respective cylinder is substantially closed; and before the respective piston moves to at most 35 degrees, preferably at most 45 degrees, prior to top dead centre.

    Abstract: A collector device for determining a metal in an exploration sample containing a concentration of the metal not directly detectable by X-ray fluorescence (XRF), comprises an adsorbent material capable of concentrating metal from a digestion mixture produced by digesting the exploration sample, which is configured for association with an analysis window of the XRF detector to facilitate determination of the amount of metal value in the exploration sample. A sample preparation vessel, method and system used to prepare exploration samples for analysis includes a vessel for receiving the exploration sample, a digestion tablet and a digestion medium; a closure to allow the vessel to be agitated to produce a digestion mixture comprising dissolved metal and the collector device. The closure and the collector device are coupled so that collector device is retrieved from the vessel by removing the closure. The digestion tablet includes a metal lixiviate and an alkali compound.
