Abstract: Provided is a method for a dynamic state estimation of a natural gas network considering dynamic characteristics of natural gas pipelines. The method can obtain a result of the dynamic state estimation of the natural gas network by establishing an objective function of the dynamic state estimation of the natural gas network, a state quantity constraint of a compressor, a state quantity constraint of the natural gas pipeline and a topological constraint of the natural gas network, and using a Lagrange method or an interior point method to solve a state estimation model of the natural gas network. The method takes the topological constraint of the natural gas network into consideration, and employs a pipeline pressure constraint in a frequency domain to implement linearization of the pipeline pressure constraint, thereby obtain a real-time, reliable, consistent and complete dynamic operating state of the natural gas network.

Abstract: In a group chat-based instant messaging method, a message is received from a first messaging application of a first user in a first messaging group. The first messaging application is associated with a first messaging service. When the message is to be announced to all group members of the first messaging group, whether the first user is authorized to send the message is determined based on identity information of the first user. Based on the first user being authorized, protocol conversion on the message is performed based on a second messaging protocol of a second messaging service to output the message in a first preset announcement style for messages announced to all group members. The converted message is transmitted, via a second messaging server, to a second messaging application corresponding to one of the plurality of group members in the first messaging group.

Abstract: Technologies relating to model interpretation are described herein. A text classifier is provided with input text and assigns a class to the input text from amongst several possible classes. Based upon the class assigned to the input text by the text classifier, a class profile of a centroidal classifier is selected, where the class profile is constructed based upon numerous input texts to which the text classifier has previously assigned the class. Based upon the selection of the class profile, information that is indicative of operation of the text classifier with respect to the text classifier assigning the class to the input text is output, where the information includes an exemplar text sequence.

Abstract: Technologies related to predicting whether a requested change (deployment) in a cloud computing environment will fail are described herein. An exposomic feature value is computed based upon a time series of risk values, where the risk values represent risk of failure over several historic time intervals. A probabilistic model computes a likelihood that the requested deployment will fail during implementation of the requested deployment based upon the exposomic feature value and a contextual feature value, and a notification is transmitted to a computing device of a change manager to allow the change manager to take remedial action.

Abstract: A transport arrangement system operates to provide a service, which can receive a transport pool request from a rider. The transport pool request can specify a set of parameters, including a pickup location and a drop-off location. A candidate set of transport providers are identified that satisfy one or more criterion, including a criterion of proximity relative to the pickup location. One of the candidate set of drivers is selected to provide a transport pool for the rider. The selection can be based at least in part on determining which individual drivers of the candidate set satisfy one or more constraints, including a first constraint that relate to a predicted trip completion time for the rider.

The historical data compaction compacted data files associated with a first database table into one data file. A configuration for a data compaction to be performed on a plurality of data files associated with a second database table is generated based on the first and second information. The data compaction is performed during a future time period. In other embodiments, a system and a computer program product are disclosed.

Abstract: Extraction of platinum-group elements, e.g. Pd, by adsorption from acidic aqueous solutions, using chelating acrylic fibers having amidoxime substituents followed by recovery by elution with an HCl-thiourea solution. From about 10% to 100% of the acrylic fiber CN are converted to amidoxime by reaction with NH2OH (hydroxylamine) in H2O/MeOH solution in the range of 30° C.-90° C. for from 15 min to 72 hrs. The adsorptive loading of elements onto the fiber and the efficiency of elution therefrom is substantially 100%, in multiple cycles of adsorption/elution. The novel fiber/extraction process is rapid, lending it to a continuous recovery operation. A portion of the CN groups of may be converted to carboxylate groups by reaction with NaOH. Short lengths of fiber are loaded into a vertical column and the pregnant solution introduced. Upon breakthrough, the fibers may be eluted, washed and recycled hundreds of times without removal from the column.

The system can cause the computing device of the requesting user to display a ride service selection interface comprising a graphic feature indicating the guaranteed upfront cost for the specified transport option. Based on a user selection of the graphic feature, the computing system can select a driver from the one or more available drivers based, at least in part, on a proximity of the selected driver to the current location of the requesting user, and determine a rendezvous point at which the requesting user can rendezvous with the selected driver.

Abstract: Provided is an optimization control method for stable operation of an aerial work platform. For an articulated boom type aerial work platform which does not overturn in three preset operational states, the maximum angle ?max of a folding boom angle ? is substituted into a known first stability control function L=g (?, ?, S) to obtain an optimized second stability control function L=f (?, S). The three preset operational states include: State I—a folding boom is fully extended at a maximum angle, and a main boom is fully retracted at a maximum angle; State II—the folding boom is fully retracted at a minimum angle, and the main boom is fully retracted at a maximum angle; and State III, the folding boom is fully retracted at a maximum angle, and the main boom is fully retracted horizontally.
