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: 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.

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.

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.

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.
