Abstract: A prediction method for coal and gas outburst based on comparing borehole gas flow curves includes the following steps: constructing a seam-crossing borehole in the coal seam, measuring or calculating gas flow corresponding to critical gas pressure P, which is a reference gas flow Q(t)reference; performing linear regression on the reference gas flow Q(t)reference to form a reference flow curve; constructing a predicted seam-crossing borehole in a predicted area, and directly testing a gas flow at each time t in a delayed manner, which is a predicted gas flow Q(t)prediction; performing linear regression on the predicted gas flow Q(t)prediction to form a predicted flow curve; and judging whether the predicted flow curve is above the reference flow curve or whether the predicted flow curve intersects with the reference flow curve, and judging whether the coal seam in the predicted area has a risk of coal and gas outburst.

Abstract: Disclosed are a method and apparatus for transmitting data in an IoT system. The method includes: determining a data type of device data sent by an IoT device when a connection between a gateway device and a server is abnormal; storing device data of a real-time data type into a first message queue of a message-oriented middleware, and storing device data of a historical data type into a second message queue of the message-oriented middleware; transmuting the device data in the first message queue to a server over a first MQTT channel and transmitting the device data in the second message queue to the server over a second MQTT channel when the connection resumes to a normal state.

Abstract: Described are techniques for displaying a user interface of an application. A property file identifies a user interface element included in the user interface and specifies a first value for a first property of the user interface element. Executing the application includes: creating the user interface element having a set of properties and a default value for each property in the set; obtaining and processing the property file, setting the first property to the first value rather than the default value, wherein if the first value is not specified in the property file, the first property is set to the default value; and displaying the user interface including the user interface element in accordance with the first value.

Abstract: A method for modifying a positive electrode material for a lithium-ion battery. The method includes: a) grinding a mixture of manganese dioxide and lithium carbonate, and calcining the mixture at no less than a temperature of 600° C. for no less than 20 hrs in the presence of air, to yield a powdery lithium manganese oxide (LiMn2O4); b) adding a precursor for forming a graphene-like structure to the powdery LiMn2O4, mixing, curing at a constant temperature of no less than 180° C. for between 2 and 4 hrs, grinding, and calcining at no less than a temperature of 500° C. for between 1 and 50 hrs in the presence of an inert gas, to yield a composite powder comprising a graphene-like structure and LiMn2O4; and c) collecting and sintering the composite powder at a temperature of between 300 and 500° C. for between 1 and 10 hrs in the presence of air.

Abstract: The invention provides, in some aspects, methods and systems for customizing data processing equipment by storing, on a removable storage device, a predetermined data set of customer requirements. The removable storage device is coupled to a data processor executing a default data set of customer requirements. The data processor executes, from the removable storage device, the predetermined data set of customer requirements, thereby causing a non-disruptive customization of the data processor from the default data set of customer requirements to the predetermined data set of customer requirements. Removing the storage device from the data processor causes a non-disruptive customization of the data processor from the predetermined data set of customer requirements to the default data set of customer requirements.

Abstract: Described are techniques for performing a content view search. A hierarchical structure of content views is provided. The content views are registered with an application framework. Query terms are received. The application framework determines nodes in the hierarchical structure having an associated keyword matching the query terms, determines a first list of node identifiers identifying the nodes in the hierarchical structure matching the one or more query terms, and determines a second list of descriptions corresponding to node identifiers of the first list. The second list of descriptions is displayed. Responsive to a selection of a first description from the second list, a first node identifier is determined that corresponds to the selected first description. A first content view for the first node identifier is displayed.

Abstract: Described are techniques for event notification. A first notification about a first event is received. A timer is set to an amount of time. Processing waits until an occurrence of either receiving a second notification of a second event or expiration of said timer indicating that the amount of time has lapsed. It is determined whether the amount of time has lapsed or whether the second notification has been received. If the expiration time has lapsed, notification of the first event is provided, and otherwise, if the second notification has been received prior to the amount of time lapsing, the timer is reset and processing waits for an occurrence of either receiving a next notification of an event or expiration of the timer indicating that the amount of time has lapsed.

Abstract: An improved technique of providing content from a single point of entry to a user is presented. The technique includes providing, on a computerized device, a unified content database from a set of content databases including a first content database of a first application and a second content database of a second application. The technique also includes displaying, from the computerized device to the user, a navigation view based on the unified content database while the first and second applications run on the computerized device, the navigation view initially rendering a single access point for content to the user. The technique further includes updating the navigation view with content from the first and second content databases in response to navigation commands from the user, the unified content database identifying particular database entries in the first and second content databases based on the navigation commands from the user, each database entry including displayable content.
