Abstract: A virtual content server and method are provided for virtual content providers to provide multiple items of their virtual to users as part of an ordered virtual content campaign. A provider may define the order for the presentation of the content items, such as a linear sequence or based on a particular logic, e.g., a state transition graph or matrix, and such order information is stored in a campaign database. The server stores information regarding the state of the campaign for a particular user, e.g., how many or which ones of the content items of the ordered campaign have been presented to the user. Additionally, the provider may define certain performable actions with respect to particular states or content items. Actions performed by the user may be detected, and the server may store information regarding performed actions in association with the user id.

Abstract: A method for designing an electromagnetic gradient coil for magnetic resonance imaging systems. The method includes the steps of: choosing a set of objectives Li, whereby the objectives Li are combined to one weighted-sum objective function; choosing a design variable ? for modifying the value of the objectives L; making an initial guess of the value of the design variable ?; simulating the magnetic field in a computational domain with respect to the distribution of the surface current density; carrying out a sensitivity analysis by calculating a sensitivity vector G=?L/??; updating the design variable ?, whereby the value of the design variable ? is changed in order to decrease the value of the objective L; determining whether convergency is achieved by either determining whether the value of the objective function does not decrease or the whether the Euclidian norm of the sensitivity vector G approximate to zero; and reconstruction of a discretized coil.

Abstract: Systems and methods are provided for correcting absorb sets and near absorb sets in the (2048, 1723) LDPC code used in 10 GBase-T transmission systems. Absorb sets and near absorb sets correspond to error patterns that, due to the structure and imperfections of the LDPC code, cannot easily be corrected using standard correction methods. To correct these error patterns, a set of failed syndrome checks associated with the error pattern can be identified, and the 4, 8, 12, or 16 error patterns associated with the failed syndrome checks can be determined. The codeword may then be corrected based on the error pattern that most likely occurred.
