Biological object detection
As the capabilities of digital histopathology machines grows, there is an increasing need to ease the burden on pathology professionals of finding interesting structures in such images. Digital histopathology images can be at least several Gigabytes in size, and they may contain millions of cell structures of interest. Automated algorithms for finding structures in such images have been proposed, such as the Active Contour Model (ACM). The ACM algorithm can have difficulty detecting regions in images having variable colour or texture distributions. Such regions are often found in images containing cell nuclei, because nuclei do not always have a homogeneous appearance. The present application describes a technique to identify inhomogeneous structures, for example, cell nuclei, in digital histopathology information. It is proposed to search pre-computed super-pixel information using a morphological variable, such as a shape-compactness metric, to identify candidate objects. |

Determining recommended orders for configurable products on a multi-dimensional basis
A multi-dimensional recommended order system generates recommended orders for configurable products. The multi-dimensional recommended order system generates the recommended orders based on a multi-dimensional demand and sales metrics analysis.

Providing data of a memory system based on an adjustable error rate
A first data stored at a first portion of a memory cell and a second data stored at a second portion of the memory cell are identified. A first error rate associated with first data stored at the first portion of the memory cell is determined. The first error rate is adjusted to exceed a second error rate associated with the second data stored at the second portion of the memory cell. A determination is made as to whether the first error rate exceeds a threshold. The second data stored at the second portion of the memory cell is provided for use in an error correction operation by a controller associated with the memory cell in response to determining that the first error rate exceeds the threshold. |

Object format resilient to remote object store errors
Techniques are provided for remote object store error handling. A storage system may store data within one or more tiers of storage, such as a local storage tier (e.g., solid state storage and disks maintained by the storage system), a remote object store (e.g., storage provided by a third party storage provider), and/or other storage tiers. Because the remote object store may not provide the same data consistency and guarantees that the storage system provides for clients such as through the local storage tier, additional validation is provided by the storage system for the remote object store. For example, when data is put into an object of the remote object store, a verification get operation is performed to read and validate information within a header of the object. Other verifications and checks are performed such as using a locally stored metafile to detect corrupt or lost metadata and/or objects. |

Debugging of memory operations
A debugging tool, such as may take the form of a software daemon running in the background, can provide for the monitoring of utilization of access mechanisms, such as Direct Memory Access (DMA) mechanisms, for purposes such as debugging and performance improvement. Debugging tools can obtain and provide DMA utilization data, as may include statistics, graphs, predictive analytics, or other such information. The data can help to pinpoint issues that have arisen, or may arise, in the system, and take appropriate remedial or preventative action. Data from related DMAs can be aggregated intelligently, helping to identify bottlenecks where the individual DMA data might not. A debugging tool can store state information as snapshots, which may be beneficial if the system is in a state where current data is not accessible. The statistics and predictive analytics can also be leveraged to optimize system-performance. |

The disclosure provides a method, a device and a system for fault detection. The fault detection method includes following steps: acquiring interactive data generated during a working process of a target Internet of Things system, and generating data to be detected based on the interactive data; detecting whether the data to be detected is fault data or not, and performing an emotion analysis on the data to be detected which is judged as the fault data to obtain a corresponding emotion label; and extracting a corresponding fault type from a preset fault emotion mapping table based on the emotion label and outputting the fault type. In this disclosure, the interactive data is analogized to human emotions, and the faults are accurately found through the emotional analysis on the data, thereby achieving the fault detection of the Internet of Things system in a convenient, flexible and accurate manner. |

Devices, methods, and user interfaces for providing audio notifications
An electronic device is in communication with one or more wearable audio output devices. The electronic device detects occurrence of an event and outputs, via the one or more wearable audio output devices, one or more audio notifications corresponding to the event. After beginning to output the one or more audio notifications, the electronic device detects an input directed to the one or more wearable audio output devices.

Method for identifying bus nodes in a bus system
A method for identifying bus nodes in a bus system makes it possible to be able to operate bus slaves of two different types in mixed systems. The detection of which bus slave has not yet been allocated an address in an addressing phase is carried out differently depending on a type of the bus slave. In all cases, however, the bus slave connected to the bus line farthest away from the bus master is identified as that bus slave to which an address is to be allocated. |

Closed loop performance controller work interval instance propagation
Systems and methods are disclosed for scheduling threads on an asymmetric multiprocessing system having multiple core types. Each core type can run at a plurality of selectable voltage and frequency scaling (DVFS) states. Threads from a plurality of processes can be grouped into thread groups.
