A ground shield structure is suitable for use in a circuit structure. The ground shield structure has a plurality of ground cells that are arranged on a ground plane periodically, compactly and complementarily. The slots between the ground cells are used to reduce the eddy current generated on the ground shield structure. The ground shield structure increases the slow-wave factor to slow the waves so that the area of the circuit layout can be decreased. Besides, the ground shield structure can reduce the energy loss of the inner circuit of the circuit structure and can increase the quantities of inductance and capacitance in per unit area thereon.

A method of hindering the propagation of a computer virus on a computer network is disclosed. The computer network comprises a plurality of addressable connections capable of receiving data from at least one computer system, and a detection computer arranged to detect the presence of a computer virus. The method comprises: operating the detection computer to monitor the plurality of addressable connections thereby to detect the presence of a computer virus on at least one of the addressable connections; in the event that a computer virus is detected, identifying the at least one computer system that sent the computer virus to the at least one addressable connection; and sending virus remediating means to the at least one identified computer system, the virus remediating means being arranged at least to hinder the operation of the computer virus. A computer program and computer system for hindering the propagation of a computer virus is also disclosed.

A method and apparatus for propagating updates in databases are disclosed. For example, the present method uses “blocking” and / or “thresholding” to delay update propagation and / or to limit the propagation of updates to an optimal stage. For example, the present method receives at least one database update and extracts at least one token from the at least one database update. The method then determines whether a threshold for propagating the at least one database update for the at least one token is reached. The method then propagates the at least one database update for updating an index structure of a database pertaining to the at least one token whose threshold has been reached.

The invention relates to a Method for calculating a local extremum, preferably a local minimum, of a multidimensional function E(x1, x2, . . . , xn) which is interpretable as a function of potential energy with spatial coordinates (x1, x2, . . . , xn), using an iteration process based on a molecular dynamics based quenching method comprising the following steps: a) Calculating a trajectory X(ti) at discrete times ti=Σiδti starting from an assigned initial coordinate X(0) on basis of a gradient fk=δE / δxk with k=1, . . . ,n and a time derivatives of the coordinates vk=dxk / dt using fxk=mxk dvxk / dt in which mxk represent masses at the spatial coordinates and vxk=dxk / dt represents velocity b) Performing a molecular dynamics based quenching method for analysing said function E(x1, x2, . . . , xn) of existence of a local extremum, in case of reaching a local extremum abort processing and / or select a new initial coordinate and proceed further from step a) c) Calculating at each iteration time step δti F=(fxk) and (k=1, . . . ,n) representing a global force vector field acting in the spatial coordinates, V=(vxk) representing a velocity vector field, P=F·V representing power Setting V=(1−α)×V+α×(F / |F|)·|V|α is a dimensionless variable and amounts a given initial value αstart at first iteration time step In case of P<0: V is set to zero, α becomes αstart, δti will be reduced and return to step b) In case of P≧0: Analysing whether the number of conducted iteration steps since the last detected case of P<0 exceeds a given minimum number Nmin, in case of “no” returning to step b) and in case of “yes” increasing δti, decreasing α and return to step b).

The delayed start-up verbal warning unit includes an audible alarm that comprises a verbal warning and instructions. The unit is connected to a control circuit for machinery, e.g., an oil well pumping unit. The control circuit includes a means of generating a start-up signal for the machinery. Where the machinery is an oil well pumping unit, the unit operates to issue a verbal warning and instructions related to imminent start-up of the pumping unit. Playback of the verbal warning delays propagation of the start-up signal to the pump, thereby providing people in the area the opportunity to avoid injury by evacuating the area. Additionally, start-up signal status may be sent by the unit to a Supervisory Control And Data Acquisition (SCADA) system for further processing and analysis.

The invention relates to a sorting device and method for sorting granulated mass containing varied materials, such as granulated mass containing varied materials, such as granulated electronic scrap. According to the invention, the sorting device comprises a planar, elongated trough conveyor (1) having at least a first elongated and vertical edge (2, 3, 4); a feeding device (5) for feeding the mass into the first end (6) of the trough conveyor, a vibrator (9) provided with a motor (7) and an eccentric (8), whose rotation axis (10) is disposed in a plane deviating from the plane defined by the trough conveyor so that the mass proceeds obliquely forwards in the trough conveyor towards the first edge and second end (11); a first suction device (12) for removing the lightest surface portion of the mass near the edge, a guide (13) which is oblique with respect to the edge for bringing apart the mass flow from the edge; as well as a mechanical separator member (14) for dividing the mass flow into two parts.
