Abstract: The invention discloses method and apparatus for operation and maintenance of a battery and an electronic device. The method includes: performing a charging/discharging process on a to-be-analyzed battery cluster, and determining key battery parameters (KBP) of a plurality of cells in the battery cluster; determining whether the battery cluster is abnormal depending on whether the KBPs of the cells in the battery cluster exceed a normal range; and performing operation and maintenance on the battery cluster in a case that the battery cluster is abnormal. The internal resistance, the capacity parameter, and the self-discharge parameter of the cells are used as the KBPs of the cells. Based on the KBPs, whether the cells are abnormal can be determined more accurately, and the cause of the abnormality can be determined. Accordingly, more accurate operation and maintenance can be subsequently realized for the battery cluster when required.

Abstract: Source code of a golden version and a next version of a program is received in which procedure calls are modified to call from an entry point table (EPT) with index numbers corresponding to procedure memory addresses. An executable defect-free golden version program and next version program with a defect are received. A first entry point table (first EPT) for the new version program and a second EPT for the golden version program are generated. A series of substitutions of procedures from the second EPT to the first EPT is performed and an order of substitutions includes: a module set, a module of the module set, a procedure set of the module, and a procedure of the procedure set. The defect producing procedure is identified by substituting in order until the defect is absent and proceeding to the next substitution in order.

Abstract: Global variables are shared between programs associated with different addressing modes. A first program of an application records an allocated address to a global variable in a global variable sharing area (GVSA). The first program is associated with a first addressing mode. The first program specifies the global variable to be shared across different addressing modes. An address of the GVSA is passed to a second program of the application that is loaded after the first program has been loaded. The second program is associated with a second addressing mode different from the first addressing mode. The second program also specifies the global variable in the second program to be shared across different addressing modes. The second program retrieves the allocated address to the global variable from the GVSA based on the address of the GVSA. The second program accesses the global variable based on the retrieved allocated address.

Abstract: In an example embodiment, a framework to infer a user's value for a particular attribute based upon a multi-task machine learning process with uncertainty weighting that incorporates signals from multiple contexts is provided. In an example embodiment, the framework aims to measure a level of a user attribute under a certain context. Rather than attempting to devise a universal, one-size-fits-all value for the attribute, the framework acknowledges that the user's value for that attribute can vary depending on context and factors in the context under which the user's attribute levels are measured. Multiple contexts are defined depending on different situations where users and entities such as companies and organizations need to evaluate user attribute levels. Signals for attribute levels are then collected for each context. Machine learning models are utilized to estimate attribute values for different contexts. Multi-task deep learning is used to level attributes from different contexts.

Abstract: A call to an external interface to execute a target callee program associated with a first addressing mode in a secondary runtime environment (RTE) is received from a caller program associated with a second addressing mode running in a primary RTE. An address of a share area (SA) storing existing dynamic link object information in the primary RTE in storage is passed to the secondary RTE. The SA is accessible by both the caller program and the target callee program. In response to a request to load a dynamic link object by an initiating program during execution of the target callee program in the secondary RTE, an entry address of the dynamic link object is retrieved in the SA. The dynamic link object is loaded based on the retrieved entry address of the dynamic link object.
