The description relates to the field of automatically predicting the performance characteristics of a service-oriented architecture (SOA). The prediction is made by setting up a model of the service-oriented architecture, generating a queue of services to be executed, simulating execution of the services by utilizing the model while processing the queue, and determining the performance characteristics from data obtained from the simulation.

Automated performance prediction for service-oriented architectures

A method for performing a modularization of an arbitrary structured hypertext with a physical structure and an organizational structure description is disclosed. The hypertext is decomposed into a set of separate modules with specific definable boundaries based on both, the physical structure and the organizational structure description, each module of the set of modules is computed methodically and gradually with respect to coaction with the other modules until forming a completed functional unit reusable and invocable separately. Furthermore, a corresponding hypertext, a module, a computer system, a computer program product and a computer program are disclosed.

Method for performing a modularization of a hypertext

An embodiment includes a method that includes receiving, into a cache server, from a client, a request for content from a content server. The request for content includes one or more fields. The method also includes mapping the request for content into a new request for content that is without the one or more fields. The method includes performing a lookup into a cache list of the cache server based on the new request for content.

Mapping of a content request for a cache server

A learning system, method, and data structure provides collaborative activities between learners. The system includes an interface to receive a learning strategy selected by a learner. A content management system stores content and one or more collaboration elements associated with a course. A learning management system determines the learning content and the one or more collaboration elements to present to the learner based on the selected learning strategy. The learner participates using the collaboration element at a time of the learner's choosing while taking the course. The collaboration activity may be based on one or more collaboration scenarios including a brainstorming activity, a cooperative text processing activity, an explanation discourse activity, an answer-to-tutor activity, and a pro-contra dispute. The collaboration element may be provided as an intentional point of collaboration.

Instructional architecture for collaborative e-learning

A repository manager and copy editor may be used to create an offline course, which allow learners to process course material locally on their computer without the need to connect to the e-learning system. A generic packaging list is created when the course is offered offline. A specific packaging list customized for the learner is created when the offline course is downloaded. An offline manager tool provides an interface for taking the course offline.

Offline e-courses

A learning system, method, and data structure provides collaborative activities between learners. The system includes an interface to receive a learning strategy selected by a learner. A content management system stores one or more structural elements associated with a course. A learning management system determines the learning content and the one or more structural elements to present to the learner based on the selected learning strategy.

Structural elements for a collaborative e-learning system

A learning system may be used to dynamically create courses tailored to the needs of a learner. In one implementation, the learning system may dynamically create, assemble, and/or build new temporary courses from the structural elements of an existing course according to the specific needs of a learner. The learner's needs may be expressed using a budget and other criteria provided by the learner. Using the budget and criteria, the learning system may identify existing structural elements that may be used to assemble a dynamic course. After the course is assembled, the course may be temporarily stored and presented to the learner using the learning station.
