A mechanism for the flow of access by derivation is provided. An access point may be any object, such as files or functions, to which the access recipient is granted access rights by the access provider. Access is typically represented by a relationship object referencing the access provider function, the access recipient function, and the access point object, and a set of access rights. This membership access relationship object is typically represented as a subtype of the access relationship. When a membership access relationship is created, typically a new associated persona function is generated, representing the new identity created for the access recipient function while serving as a member of the access point function. When a persona function is invited to be a member in another function, that in turn generates a membership and a second persona that is derived from the first persona, resulting in identity derivation.

The productivity of sandstone or carbonate formations is enhanced by contacting the formation with a deformable particulate and a HF-containing acidizing solution. The deformable particulates create a partial monolayer in the formation while the HF-containing acidizing solution differentially etches the rock around the deformable particulate. The surface of the formation is partially blocked from reaction with the acidizing solution by the creation of the partial monolayer. Conductive channels are therefore created on the surface of the formation. The deformable particulates deform on closure. As the closure stress increases, the formation faces compress the non-dissolved, sandwiched formation points. These points function as pillars of un-reacted formation and act similar to a partial monolayer of proppant, providing the highly conductive channels.

The present invention relates to a policy resolution method and system, access network and terminal device for enabling modular network-assisted policy resolution, wherein the policy resolution is divided into separate stages each handling specific types of trigger events and performing specific types of policy actions. The separate stages are processed in a chronological order during a policy resolution round, and trigger events which occur during a policy resolution round are frozen until the start of the next policy resolution round. Thereby, modular policy resolution with reduced delays and oscillations can be achieved. Moreover, policy processing can be divided into a policy decision point functions in the network and a policy enforcement point function in the network or terminal device, so that terminal resources used for policy resolution can be saved.

The present invention relates to a method and system for obtaining a point spread function for deblurring image data captured by an imaging device comprising a motion sensor. First, motion path values indicating the motion of the imaging device during the exposure time are acquired. The motion path values of the imaging device are then projected onto the sensor plane and for each sensor pixel the projected motion path values are integrated over time. Said integrated value represents for each sensor pixel an initial estimate of the point spread function. Optionally, the size of the point spread function can also be estimated based on the distance of the focused object and taken into account during the projecting step.
