Abstract: A method and system for controlling load admission rate of an application server is provided. In the method, actual heap utilization and load admission rate of the application server in current control cycle are detected; based on the detected actual heap utilization and load admission rate, load characteristics variation parameters of the application server are estimated; and control gain of a feedback controller is calculated based on the load characteristics variation parameters; the feedback controller calculates desired load admission rate of the application server in next control cycle by using the calculated control gain. The load admission rate of the application server can be adaptively controlled by tracking changes in workload characteristics of the application server, such that the actual heap utilization of the application server is maintained at or close to target heap utilization.

Abstract: A location estimation method using label propagation. The achieved location estimation method is robust to variations in radio signal strengths and is highly accurate by using the q-norm (0<q<1), especially, for calculating the similarities among radio signal strength vectors. The accuracy in location estimation is further improved by putting more importance on the time-series similarities. Specifically, the time-series similarity is calculated by using time-series values indicating the temporal order of radio signal strengths during the measurement. If the time-series similarity is larger than the similarity between the radio signal strength vectors, the time-series similarity is preferentially used. The exponential attenuation function can also be used for calculating the similarities, instead of the q norm (0<q<1).

Abstract: Variations of waiting times of requests for services handled by a processor are minimized. In response to the processor receiving a request for a service, an arrival time of the request for the service is recorded and added to a total arrival time for all requests for the service, and a counter of a number of waiting requests for the service is incremented. In response to the processor processing the request, the arrival time of the request is subtracted from the total arrival time, and the counter is decremented. In either case, an average waiting time of requests for the service is determined, a history of the average waiting times is maintained, and the variation within this history is determined. Where the variation is greater than a threshold, processor resources are adjusted to minimize variations within waiting times of requests for all the services handled by the processor.

Abstract: Disclosed is a means and a method for executing a nested transaction in an execution environment supporting flat transactions only. To process a StartTransaction operation within a nested transaction it is suggested to check whether the StartTransaction operation is on the first nesting level of the nested transactions. An actual transaction within the execution environment by issuing a corresponding StartTransaction is started only in the affirmative case but not otherwise. To process a CommitTransaction operation within a nested transaction to successfully terminate a transaction it is suggested to check whether the CommitTransaction operation is on the first nesting level of the nested transaction. An actual transaction within the execution environment will be terminated only by issuing a corresponding CommitTransaction operation in the affirmative case but not otherwise.
