Abstract: Disclosed is a computer-implemented method of predicting the required number of servers for a future computing workload. The method comprises determining the number of servers in three classes of servers and predicting the future number of servers in the different classes based on a Susceptible-Infected-Recovered-Algorithm. The three classes are, class S are servers that are adapted to deploy the application, class I are servers that deploy the application and class R are servers that are disconnected from the network. The algorithm is based on the deployment rate, un-deployment rate and a removal rate. The deployment rate is the number of servers leaving class S moving to class I, the un-deployment rate is the number of servers leaving class I moving to class S, and the removal rate is the number of servers leaving class I and moving to class R, all in unit time. Such that the total number of servers required in the topology of the computer network in the data centre at a future time t is calculated.

Abstract: Temporary authorisation for access to protected operations is controlled based on user capability for a proposed activity. An escalation request may be received for a protected activity by a user not authorized to perform the protected activity. Activity indicator(s) indicative of a skill required to perform the protected activity may be compared with user skill indicator(s) to determining an indication of a capability of the user to perform the protected activity and a temporary authorization granted or denied lasting for a limited time window. Escalation requests may be assigned to activity catagories. A skill coefficient may be used to indicate experience in different skills catagories. The performance of the activity may be monitored to update the user skill level, and where requests are denied learning actions may be provided to the user.

Abstract: A first component of a first computer system, such as a wireless mobile device, registers that it can execute various actions requested by applications running on the system. The actions may be sensing a physical quantity or running a background service. When a request to execute an action is received, the component determines whether the action should be executed by a local component or a remote component. The remote component may be on a further mobile device near the first computer system or it may be a remote computer provided by a network service. The first component executes the action on a remote component if there is no local component capable of executing the action. If there are suitable local and remote components, the choice may be based on a metric, such as battery level, network bandwidth, processor usage or memory usage.

Abstract: Enhancing a mind map using a content pool with information items, performing a first semantic scan based on a selected object and generating a new object and a related connection to the selected object based on the semantic scan. A strength value for each of the connections of the first mind map and the connection with the lowest strength value is determined and recalculating the strength value using an (d) external knowledge base to define the connection as obsolete if the strength value decreases. The cycle may be iterated for data from a browser or chat history, a document in a folder or cloud storage, e-mail database, or a content management system. The mind map may then be presented to the user for easy visualisation of links between topics in large data sets, as spider grams.

Abstract: A diagnosis system comprising a diagnosis server and electronic noses, the diagnosis server comprises a receiver unit for receiving a set of data from one out of a plurality of e-noses. The set of data comprises a sensor identifier, a sensor output value, and a relevance flag for a predefined diagnosis. A determination unit in the diagnosis server determines a probability factor for the predefined diagnosis based on the set of data, a relevance function and a distribution function wherein the relevance function is indicative of the relevance of the sensor output value for the predefined diagnosis and wherein the distribution function is indicative of a distribution of the sensor output value for the predefined diagnosis.
