A method is implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions. The programming instructions are operable to receive one or more risk factors, receive one or more contexts, identify one or more context relationships and associate the one or more contexts with the one or more risk factors. Additionally, the programming instructions are operable to map the one or more risk factors for an associated context to a software defect related risk consequence to determine a risk model and execute a risk-based testing based on the risk model to determine a defect related risk evaluation for a software development project.

A method of mapping system addresses to physical addresses associated with a physical memory device receives memory requirements associated with an application, allocates a region of the physical memory device to the application (wherein the region is a contiguous portion of the physical addresses that does not overlap with any other region and is associated with a memory mapping mode), determines a memory mapping scheme for the region (wherein the memory mapping scheme defines the mapping between system addresses and the region and is based at least on the memory mapping mode) and modifies a mapping register to reflect the region. In one implementation, the method modifies the mapping register to reflect the memory mapping scheme. In another implementation, the memory requirements comprise an application type, and the memory mapping mode is determined based on the application type.

A series/parallel hybrid electric drive unit for vehicle comprises an engine (1), a main traction motor (2), an integrated starter-generator (3), a differential (4), a first shaft (main haft) (5), a first stage decelerating device (9), a second stage decelerating device (10), a first clutch (6), a second clutch (7) and a synchronizer (8). The synchronizer (8) is slidably arranged on the first shaft (5) which is connected to the first stage decelerating device (9) or the second stage decelerating device (10) by the synchronizer (8), respectively. The hybrid electric drive unit of the invention has a compactly-arranged internal structure and an efficient and appropriate internal connection, and a switch between connection and disconnection of respective hybrid power sources and wheels and a shifting among operating modes and gear positions of the hybrid drive system can be realized.
摘要:
A method and an apparatus for generating test cases of a software system. The method includes the steps of: tracing a user request to acquire IT events related to each service and/or component invocation; forming IT transactions based on correlation information in IT events; correlating said IT transactions based on predetermined correlation rules, in order to form a business transaction; and extracting from the business transaction a business transaction pattern corresponding to said business transaction. The method further includes generating test cases of a software system based on the generated business transaction pattern. The apparatus includes hardware for accomplishing the foregoing method steps.
