A method is disclosed for controlling operation of an engine coupled to an exhaust treatment catalyst. Under predetermined conditions, such as after an engine cold start, the method operates an engine with a first group of cylinders having a first ignition timing, and a second group of cylinders having a second ignition timing more retarded than the first group. In addition, the engine control method also provides the following features in combination with the above-described split air / lean mode: idle speed control, sensor diagnostics, air / fuel ratio control, adaptive learning, fuel vapor purging, catalyst temperature estimation, default operation, and exhaust gas and emission control device temperature control. In addition, the engine control method also can change to combusting all cylinders at substantially the same ignition timing under preselected operating conditions such as fuel vapor purging, manifold vacuum control, and purging of stored oxidants in an emission control device.

Techniques for detection and treatment of myocardial ischemia are described that monitor both the electrical and dynamic mechanical activity of the heart to detect and verify the occurrence of myocardial ischemia in a more reliable manner. The occurrence of myocardial ischemia can be detected by monitoring changes in an electrical signal such as an ECG or EGM, and changes in dynamic mechanical activity of the heart. Dynamic mechanical activity can be represented, for example, by a heart acceleration signal or pressure signal. The electrical signal can be obtained from a set of implanted or external electrodes. The heart acceleration signal can be obtained from an accelerometer or pressure sensor deployed within or near the heart. The techniques correlate contractility changes detected by an accelerometer or pressure sensor with changes in the ST electrogram segment detected by the electrodes to increase the reliability of ischemia detection.

A method of managing a computing system (300) includes generating (1702) transaction requests in accordance with a transaction profile of the system (300). The transaction requests are provided for processing by the system (300). Status data of a set of managed resources (102) of the system (300) is collected (1704) in accordance with a system model stored in a knowledge base (204). Performance indicators of the system (300) are determined (1706) from the status data in accordance with the system model. The transaction performance of the system (300) is monitored (1710) by comparing the performance of the system (300) in processing the transaction requests with an expected performance. When a degradation in transaction performance is detected, a signal (1712) is generated to indicate that a degradation in performance has occurred, to enable the status data and / or performance indicators to be analysed at the time at which the performance degradation occurs. The method improves over prior art management methods by providing for the simultaneous measurement of the transaction performance of the system (300), along with monitoring of defined status and performance metrics, thereby enabling correlation between changes in performance and changes in the status of the system. A corresponding computer implemented means for managing a computer system, and computer program products, are also provided.
