Abstract: Methods, systems and computer program products for providing mutual authentication for radio frequency identification (RFID) security. Methods include receiving an authentication request at a RFID tag from a requester, where the request includes an encrypted access role. An encrypted secret message is transmitted to the requestor in response to receiving the authentication request. The encrypted secret message is based on the encrypted access role received from the requester. An access request specifying a work area and including a random number that is encrypted is received from the requester at the RFID tag. The access request was generated by the requester in response to the RFID tag being successfully authenticated by the requestor using the encrypted secret message. The requester is authenticated at the RFID tag. The authenticating includes determining the value of the random number sent by the requester and verifying that the work area is valid for the encrypted access role.

The apparatus further includes a validation algorithm processor configured to classify the applicable constraint and validate the observation model dependent on the constraint category of the applicable constraint.

Abstract: The invention provides a system adapted to enable contextual collaboration within a computer network. The invention provides a collaboration manager that supports manipulation of collaboration spaces. The collaboration spaces contain one or more collaboration elements that have potentially different collaboration modalities. The context manager maintains resources and resource interrelationships within contexts. The resources can include collaboration elements, processes, tasks, business objects, users, and/or roles. A view generator selects a set of the resources to be displayed to a user of the computer network. The invention also includes an interface adapted to allow applications to specify commands to manipulate collaboration spaces, commands to maintain resources and resource interrelationships within contexts, and queries for context-sensitive views.

Abstract: 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.

Abstract: A model-driven approach to business performance management (BPM) uses a hybrid compilation-interpretation approach to map an observation model to a runtime executable. The data aspect of the observation model is first extracted and refactored to facilitate runtime access. Next, the operational aspect of the model, such as logic for metric computation and situation detection, is compiled into code. Finally, a runtime engine interprets the refactored model and dynamically loads the generated code, according to the meta-model.

Abstract: Standardized support for management of contextual relationships, which includes specification of the context hierarchy, association of relationships with a particular context, and derivation of transitive dependencies, is provided with a Context Manager service. The Context Manager provides a programmatic interface for defining contexts and the relationships therein. The Context Manager saves the relationship facts in one or more context stores, which are organized by contexts. The Context Manager interfaces with the Ontology Manager that processes queries on relationships with respect to a given set of contexts. The Context Manager provides a high-level abstraction for relationship management in a context. Developers of business solutions can then focus on the core business logic, without worrying about the details of storing and inferencing relationships.

Abstract: A system and method for developing and enabling model-driven extensible Markup Language (XML) transformation to XML Metadata Interchange (XMI) format incorporate a strong built-in validation capability. A platform independent framework applies multiple passes of transformation, where each pass performs specific operations on internal models. Different source models are then merged into a target model.

Abstract: 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.

Abstract: A metric network provides a descriptive model that explicitly expresses the relationships among all metrics of a business enterprise. Performance of each single business entity in the operational level is measured by a set of primitive metrics, each of which measures a specific aspect of the business entity. The primitive metrics construct the base on which the whole metric network is built.

Abstract: The present invention provides novel beta-secretase inhibitors and methods for their use, including methods of treating Alzheimer's disease.

Abstract: The present invention provides in one aspect a composition having at least one croconine derivative. This composition may be disposed on a semiconductor layer which is further disposed on an electrically conductive surface to provide a dye-sensitized electrode. The dye-sensitized electrode can be assembled together with a counter electrode and a redox electrolyte to provide a photovoltaic cell. The photovoltaic cell may be used as a single cell or in tandem with other cells.

Abstract: A ball mold is composed of two half bodies and two hemispherical cavities respectively defined in the two half bodies to correspondingly match with each other to perform a ball-shaped interior inside the ball mold. Each of the two half bodies has an inner surface, at least one smooth area and at least one rough area; both areas are defined in the inner surface. Preferably, the smooth area has a gouged depth deeper than that of the rough area. Therefore, a ball molded by the ball mold has rough elevated portions corresponding to the rough areas on the ball mold and smooth recesses corresponding to the smooth areas on the ball mold. The ball only needs to be attached with pieces of artificial leather inside smooth recesses to be flush with the rough elevated portions. Thereby, the ball with two different surfaces is achieved in a convenient way without thermal pressing.

Abstract: A system and method permits a user to observe the Quality of Service (QoS) of Web services and allows dynamic selection based on the user's preference. The system is built on QoS observation meta-model and comprises a QoS observation manager, service criteria generator, service repository, evaluation manager and service invocation manager. The QoS observation manager allows users to define observation model and deploy to the service criteria generator. The service criteria generator computes the QoS criteria values of services by subscribing events which include user feedback events and service execution events, based on deployed observation model. The service repository provides the persistence storage for QoS criteria value. The evaluation manager allows users to specify selection preferences and select services based on QoS ranking. The service invocation manger invokes Web services and publishes events according to the QoS of Web services.

Abstract: 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.

Abstract: A method for making an image on a base layer includes preparing a substrate, placing an exterior layer on top of the substrate, preparing a cutting mold, cutting the exterior layer with a predetermined shape, and hot pressing the exterior layer on the substrate by the cutting mold. The cutting mold has a body, a cutting edge formed with the body and extending out from the body for cutting a portion of an exterior layer on top of the base layer, a pressing surface formed adjacent to the cutting edge for pressing an outer contour of a remaining portion of the exterior layer onto the base layer, and a space defined immediately adjacent to the pressing surface and having a shape the same as that of the image.

Abstract: A model-driven and QoS-aware infrastructure facilitates the scalable composition of Web services in highly dynamic environments. An exception management framework supports two modes of exception management for business processes, providing a novel policy-driven approach to exception management implemented in the system infrastructure. Exception management is implemented in the system infrastructure, with exception handling policies supplied by individual business processes. Using the exception management framework, developers define exception policies in a declarative manner. Before a business process is executed, the service composition middleware integrates the exception policies with normal business logic to generate a complete process schema. This policy driven-approach can significantly reduce the development time of business processes through its separation of the development of the business logic and the exception handling policies.
