摘要:
A system, method and computer program product of using peer collaboration tools to extend the reach of applications by enabling the application to specify a modality policy that is predicated on end-user context when pushing an interaction to the end-user. Various collaboration technologies—including cell phones, email, instant messaging (IM), the short message service (SMS), and pagers—have emerged that people can use to interact with each other even when they are remote and/or mobile. Using collaboration tools as the interface to Web applications eliminates the applications' dependency on Web browsers and allows applications to be accessed even when a Web browser is not available. In addition, collaboration tools are capable of receiving “calls”, which can be exploited by applications to proactively initiate and push an interaction to end users.

A flexible and extensible context server for collecting, maintaining, and disseminating context information is disclosed. The context server receives requests from requesters for context information via a secure context server interface (SCS API). Communication between the requesters and the context server is conducted by means of predetermined forms. The requests received at the SCS API are passed to a mediator, which collects data from various context drivers. Each context driver is coupled to the mediator, and collects predetermined type of context information from at least one context information source. The mediator determines the appropriate context driver which can handle the request, based on its type. Operation of the context server is also controlled by a set of context utilities, including a context cache for storing recently obtained context information, a privacy engine for storing privacy preferences and an event engine for event handling.

A system and method are disclosed for an elastic and scalable publish/subscribe scheme. Subscription information is received at a dispatcher node. A plurality of matching nodes is selected in an overlay network to store the subscription information on a computer readable storage medium. Upon receiving an event at a dispatching node, at least one of the matching nodes with the stored subscription information is selected to process the event.

A method, information processing system, and computer readable medium for modifying at least one data warehouse schema based on detected changes in an associated observation model are disclosed. The method includes determining if at least one new observation model has been created. The method also includes determining if at least one existing observation model is associated with the new observation model. In response to the existing observation model being associated with the new observation model, at least one changed attribute is identified by comparing the new observation model and the existing observation model. A set of files associated with the existing observation model is updated to reflect the changed attribute between the new observation model and the existing observation model.

Techniques for de-duplicating virtual machine image accesses. A method includes identifying one or more identical blocks in two or more images in a virtual machine image repository, generating a block map for mapping different blocks with identical content into a same block, deploying a virtual machine image by reconstituting an image from the block map and fetching any unique blocks remotely on-demand, and de-duplicating virtual machine image accesses by storing the deployed virtual machine image in a local disk cache.

Techniques, systems and an article of manufacture for caching in a virtualized computing environment. A method includes enforcing a host page cache on a host physical machine to store only base image data, and enforcing each of at least one guest page cache on a corresponding guest virtual machine to store only data generated by the guest virtual machine after the guest virtual machine is launched, wherein each guest virtual machine is implemented on the host physical machine.

A method for providing a cloud environment for provisioning a guest virtual machine instance. The method includes selecting at least one machine from a collection of machines as a management node, wherein the at least one machine includes a hypervisor enabled with nested virtualization capability, deploying a plurality of cloud managers on each management node, selecting at least one machine from the collection of machines as a host node, deploying a plurality of level two hypervisors on each host node, forming a plurality of virtual clouds, wherein each virtual cloud contains at least one of the plurality of cloud managers and one of the plurality of level two hypervisors, and provisioning, via the at least one cloud manager, at least one guest virtual machine instance on top of the at least one level two hypervisors.

The invention is a device comprising a substrate and a material provided on at least a portion of the substrate and having an exposed surface. The exposed surface of the material is non bio-adhesive. The invention further includes a non bio-adhesive material composition and a method of making a device having the same non bio-adhesive surface. The invention further provides a device having a coating of a hydrophobic material. In particular, the hydrophobic material coated portion of the device is resistant to bio-adhesion.
摘要:
A semantic publish/subscribe system enables semantic event routing and allows publishers (resp. subscribers) to use self-defined event schemas to publish (resp. subscribe) events. The constraints on value-based publish/subscribe systems that publishers and subscribers must share the same event schemas are removed. With ontology support, the system conducts event correlation based on their semantics using relational operators. Event sources are searched for subscriptions and selected events are automatically correlated according to subscriptions. The system enables efficient semantic event routing by rewriting the subscription SQL statement, wherein no redundant events are generated.
