Abstract: A method for control of a flow network in order to improve the performance of the flow network comprises: (a) applying predetermined excitations at multiple control points within the flow network, wherein the multiple control points are at different branches of the flow network; (b) receiving measurements of changes in one or more flow parameter(s) in one or more flow path(s) in which flows of more than one of the different branches have been combined; (c) carrying out an analysis of the flow parameter measurements to identify variations induced by the applied excitations; (d) determining an adjustment to be made at one or more of the control point(s) in order to improve the performance of the flow network, for example by building and solving an optimization model; (e) making the determined adjustment to the control point(s) of the flow network or making an alternative adjustment decided upon by the flow network operator; and (f) repeating steps (a) to (e) one or more times to thereby iteratively improve the

Abstract: To determine properties of multiple oil and gas wells, oscillations at different test frequencies are applied to the flow rate and/or pressure of multiple wells. Measurements of flow rate and/or pressure and temperature in flows downstream of a production header of the multiple wells are then obtained. Such measurements from the flows of the multiple wells are subjected to a frequency analysis of the pressure, flow rate and/or temperature measurements to determine pressure, flow rate and/or temperature variations induced by the applied oscillations. Properties of the different wells of the multiple wells based on the results of the frequency analysis are thus determined.

Abstract: Ultrasound acquisition Information about a structure (701) within a body is acquired by providing data defining a non-straight line (42b), at least a part of which corresponds to the structure (701); transmitting an ultrasound transmit signal (44b) into the body; receiving reflections (400-402) of the transmit signal (44b); processing the received reflections (400-402) so as to trace the focal point (403-405) of a receive beam along the path of the non-straight line (42b); using reflections (400-402) of the transmit signal (44b) from along the non-straight line (42a) to acquire information about the structure (701).

Abstract: A method for burning gas in a burner, including leading the gas through an inner fuel tube and introduction of combustion air through an annular space surrounding the inner fuel tube. This space forms of an outer tube terminated by a conically converging section, wherein the end of the inner fuel tube forms a burner head. The major part of the primary gas is introduced into the upstream end of the burner head, to go into the combustion air that flows past the burner head, whereas a smaller part of a secondary gas is introduced into the free end of the burner head and into the constricted part of the annular channel that surrounds the burner head. The gas flow is accelerated past the burner head due to the reducing cross section and is burned downstream in relation to the burning head.
