Abstract: Disclosed are apparatus and methods for determining characteristics of a target region which is embedded in background material below a body of water. In accordance with one embodiment, a resistivity background is determined. In addition, characteristics of an electric dipole due to the target region are determined. A resistance for the target region is then computed using the characteristics of the electric dipole and the resistivity background. Other embodiments, aspects and features are also disclosed.

Abstract: A joint device of an agricultural machine has at least one tool-bearing beam (2a-c, 3a-c) for soil tillage tools (4, 5, 38, 39), such as seed coulters and cultivator tines, whereby a portion (10) of the beam end, at least on one side of the machine, is detachably fastened by means of a bolt/nut connection (13, 18, 23) arranged within the tool-bearing beam. A threaded body (18, 50) in the bolt/nut connection is fixed, preferably plug welded, in the main part of the beam (2a-c, 3a-c).

Abstract: The invention refers to an implement regulating device in an agricultural machine including at least one group of implements (4) arranged across the driving direction, thereafter cross-wise arranged support members (15) and at least one each group of implements and support members are controllable and adjustable by a power device (23). Implements (4) and support members (15) in each group are journalled in bearings at one end of at least one carrying arm (13). The power device (23) is adapted to rotate a cross-running main beam (19). The main beam is connected with the carrying arm (13) via a spring member (18) and is rotatably suspended in relation to the frame (Ia) of the machine (1). Activation of the power device is adapted to influence the carrying arm between a position for maximum sowing depth and a transport position.

Abstract: The present invention relates to computer arrangements and methods for investment decision support. An advice database comprises a plurality of records for storing advice messages relating to pieces of investment advice. An advice evaluation mechanism is operable to use a set of criteria having at least one variable parameter for evaluating an advice message by determining the variable parameter in response to the advice message, checking whether the plurality of records fulfill the set of criteria and generating an evaluation result based on the result of the checking. A criteria optimization mechanism can be used to optimize the set of criteria to be used in the advice evaluation mechanism.
