The described implementations relate to distributed computing. One implementation provides a system that can include an outlier detection component that is configured to identify an outlier task from a plurality of tasks based on runtimes of the plurality of tasks. The system can also include a cause evaluation component that is configured to evaluate a cause of the outlier task. For example, the cause of the outlier task can be an amount of data processed by the outlier task, contention for resources used to execute the outlier task, or a communication link with congested bandwidth that is used by the outlier task to input or output data. The system can also include one or more processing devices configured to execute one or more of the components.
摘要:
A method for rapidly measuring melatonin adulteration of Chinese patent medicines and healthcare foods comprises: (1) extracting melatonin added to a Chinese patent medicine or healthcare food by using ethyl acetate; and (2) adding p-dimethylaminocinnamaldehyde to the extracted solution, and observing color. The method is rapid, simple and convenient, has strong specificity, high accuracy, reaction sensitivity, and a wide application range, and is applicable to on-site detection of melatonin adulteration of a Chinese patent medicine or healthcare food.
摘要:
A fitting set, including a battery assembly and a receiver having a recess for receiving the battery assembly are disclosed. The battery assembly may include a casing having a top wall, a bottom wall, two first sidewalls, and two second sidewalls. The battery assembly may further include a resilient member and a self-locking block. The first sidewalls may include notches extending to the bottom wall. The recess may include lugs on one or more of the inners walls, each of which may be engaged with a corresponding notch. The second sidewalls may each include a first stopper and one or more second stoppers, the first and second stoppers having a difference in height. The resilient member at both ends may abut against the first stopper and self-locking block, respectively, and may also press the self-locking block against an edge of the recess.
摘要:
Discovery of services between devices is provided prior to establishing a connection between devices, including wireless-enabled devices or devices that are communicatively coupled to wireless access points or other wireless communication devices. Discovering services prior to establishing a connection may facilitate finding a desired service. The services that may be discovered may be, for example, print services, camera services, PDA services or any other suitable services. Services may be discovered using 802.11, UWB or any other suitable wireless technology. As one example, particular services may be requested. As another example, services that are provided by a device may be advertised.

A novel biosensor comprises at least one fluorophore and at least two quenchers, and is capable of selectively and specifically detecting the presence of an ion in the presence of other ions.
摘要:
The normal roles of wireless stations and wireless access points in initiating the establishment of wireless connections may be reversed without the need for changes in the network interfaces for either the station or access point device. This capability may be used to allow wireless devices acting as access points, but on which service clients operate, to initiate the establishment of a connection with a station, on which a wireless service provider operates. Discovery of services between wireless devices can be provided prior to establishing a connection between the devices. A service client device providing access point functionality may broadcast an invitation for service advertisements and then receive service advertisements from relevant service providers acting as wireless stations. An information element may be included as part of periodically broadcast administrative messages to wirelessly convey an invitation for service advertisements. In response to a service advertisement, the access point may send to the wireless station an invitation to connect, prompting the wireless station to begin to establish a connection according to a wireless communication protocol.
