Abstract: A method enables analysis of (e.g. bioelectric) signals acquired by measurement. The method provides N signals U for an observation space and each has a time- and space-dependent signal characteristic U. Digitized signals for a time period T have M time points and define an M×N matrix with M tuples of N signal values each. Signal values acquired at time t form an N-tuple ?t=(U1, . . . , UN)t in a signal space. The method acquires all combinations of k tuples from the M tuples, and calculates distances between all tuples. Distance values are calculated and define edge lengths of a (k?1) simplex (SIM) with one simplex assigned to each combination of k time points. Quantity characteristics of the simplex (SIM) are encoded into color values (COL), and displays the colors in a combinatorial time lattice (CTL). Each lattice point (GP) is displayed with the color encoded for the assigned simplex.

Abstract: A hydrometallurgical process is provided for the selective extraction of one or more target metals from ore, concentrates, tailings, slags or other metal bearing solids, by combining simultaneously leaching with sorption in the state of wet solids. The sorption and leaching are performed simultaneously, which reduces the required number of process stages in comparison to conventional technologies. Performing the sorption leaching in wet solids enables a significant increase in the concentration of leaching agents in relation to target metal(s) content in solids, at the same addition rate of said leaching agents, improving thermodynamic conditions and leaching kinetics for dissolving target metal(s). The invention has the main advantage of improving metal recoveries at a reduced consumption rate of leaching agents.

Abstract: Electric welding coupler for the welding of pipes made of thermoplastic material or other weldable plastics comprising a cylindrical body made of thermoplastic material or other weldable plastics, containing at least one welding element, wherein the welding element is arranged close to the inner diameter of the cylindrical body, wherein the welding element forms at least two welding zones, a contact for feeding the electric current and at least one cavity, wherein the cavity is arranged in the cylindrical body, wherein a reinforcing ring is arranged around the outer circumference respectively outer diameter of the cylindrical body.

Abstract: A hydrometallurgical process is provided for the selective extraction of one or more target metals from ore, concentrates, tailings, slags or other metal bearing solids, by combining simultaneously leaching with sorption in the state of wet solids. The sorption is performed by means of sorbents such as ion exchange resins, activated carbon, zeolites, among others, and mixtures thereof.

Abstract: A valve includes a leakage indicator and a valve housing. The valve housing includes a valve housing upper part, a valve housing lower part, and a diaphragm. The diaphragm divides the valve housing into a fluid-flow area and a fluid-free area. The leakage indicator is an absorbent element that projects into the fluid-free area.

Abstract: A method and a system for in situ measuring and analyzing, in a continuous, non-intrusive manner in real-time, one or more compounds, typically minerals present in debris from drilling or some similar material, in powder, comminuted solids or slurry form is disclosed. The method and system provide real-time, non-intrusive, continuous in situ determination of the grade of valuable minerals present in drilling pits debris generated during excavation, with a relatively low measurement error.

Abstract: An apparatus and method of encoding eye movements and eye tracking data (DAT), represented as time and space parameters (t, x, y) obtained by an eye tracking device and assigned each to a viewpoint (A, B, C, D, E . . . ). Pairs of numbers (Z0,Z1; Z0,Z2; Z0,Z3 . . . ) are taken from the groups of numbers and are combined with each other to obtain for each combination a value (W) that indicates at least a spatial distance (S) between two viewpoints (E, C), wherein the obtained values (W) represent an encoding of the eye movement and eye tracking data (DAT). Preferably the values (W) are determined and stored in form of a first matrix (M) or array. The matrix is subjected to one or more operations (smooth filtering, anisotropic filtering, threshold filtering, anisotropic diffusion) such that the resulting matrix represents an encoding of fixations, saccades and smooth pursuit of a raw data scanpath.
