摘要:
An exemplary admixture system for cementitious compositions, comprises a polycarboxylic acid type water reducer and a tertiary amine defoamer having an average molecular weight of 100-1500 and more preferably 200-750. The defoamer permits a stable admixture formulation and helps to achieve a controllable level of entrained air in a concrete mix. Cementitious compositions and methods for modifying the same, using the tertiary amine defoamers, are also described herein.
摘要:
A composite magnetic matrix comprising a porous metal-organic framework (MOF) and a plurality of molecular magnets, where a plurality of pores of the MOF each comprise one of the plurality of molecular magnets, and where the each of the plurality of molecular magnets retains its magnetic properties in the matrix. The molecular magnet may be, for example, a single-molecule magnet or a single-chain magnet. For example, the composite magnetic matrix Mn12Ac@MOF comprises Mn12O12(O2CCH3)16(OH2)4 (Mn12Ac) as the single-molecule magnet and [Al(OH)(SDC)]n (H2SDC=4,4′-stilbenedicarboxylic acid) (CYCU-3) as the porous metal-organic framework.

A method of operation of a media distribution system includes: streaming a media object from an external system via a first browser; receiving a media request from a viewer device; determining a confirmation of whether the media request is for the media object; and serving a portion of the media object from a sandboxed memory of the first browser for presenting on a second browser of the viewer device in response to the confirmation.

摘要:
A method of producing a coagulated latex composite. A coagulating mixture of a first elastomer latex and a particulate filler slurry is flowed along a conduit, and a second elastomer latex is introduced into the flow of the coagulating mixture.

A collaboration system includes a remote server system and one or more client devices connected to the remote server system, at least one of which being a first client device that includes a touch screen display. Upon receipt of a user instruction, the collaboration system opens a document at the first client device and displays the document on the touch screen display to a first user. The collaboration system detects a first comment on the document from the first user through interacting with the touch screen display. The collaboration system receives a second comment on the document from the remote server system. The second comment is generated by a second user of a second client device and transmitted to the remote server system through a computer network. The collaboration system displays, concurrently, the first comment and the second comment on the touch screen display.
摘要:
A method of rate-control for a group of ports in a communication network. Ramping is performed for allowed-rate of each of the group of ports, if sum of the ingress-rates of the group of ports is less than a given rate threshold; and adjusting is performed for allowed-rate of each of the group of ports, if sum of the ingress-rates of the group of ports is greater than or equal to the given rate threshold, such that the sum of allowed-rates of the group of ports is equal to the given rate threshold.
摘要:
A method for optically detecting an electrical arc in a power supply. The method includes capturing light with a light pipe, transmitting the captured light along at least a portion of a length of the light pipe, optically detecting the transmitted light with a photodetector which is optically coupled to the light pipe, generating a signal indicative of an intensity of the detected light, and determining whether the detected light is associated with an electrical arc.

A system for optically detecting an electrical arc in a power supply. The system includes a light pipe, a photodetector optically coupled to the light pipe, and a signal processor connected to the photodetector.
摘要:
A method for computer assisted localization of the distal locking holes (11; 14) of an implanted intramedullary nail (2) having a nail axis (19) and a first and second distal locking hole (11; 14) by A) acquiring one single image IM of the distal end section (25) of said intramedullary nail by means of an X-ray device (9) whose optical axis (30) is oriented essentially perpendicular to the nail axis (19) but irrespective to the orientation of the distal locking holes (11; 14); and B) calculating the position of the first and second hole axis (23; 20) of the first and second distal locking hole (11; 14) with respect to a three-dimensional coordinate system A-COS (7) of the implanted intramedullary nail (2).
