System and method for automatic on-boarding of printers in a printer management system
One embodiment provides a system for facilitating device discovery. During operation, the system detects, by a computing device, a first message which is broadcast from a source device based on a network communication protocol. The system determines a classification which is a type for the source device based on a MAC address of the source device extracted from the first message. The system generates a second message which indicates the MAC address, an IP address of the source device obtained based on the first message, and the classification. The system sends the second message to a device management system, which causes the device management system to add the source device as a managed device. The system enhances device discovery by eliminating a direct scan of all devices on a sub-network by the device management system for devices of a same type as the type for the source device. |

Methods and systems for creating ICC printer profiles with unorthodox ink limits
Example embodiments relate to creating ICC printer profiles with unorthodox ink limits. A printing device may initially print a color profile chart represented by color combinations that are equal to or below an ink limit and generate a first ICC profile based on the color profile chart.

The strength of a proppant or sand control particulate may be improved by coating the proppant to form a composite. The composite has enhanced compressive strength between about 34 to about 130 MPa and minimizes the spelling of fines at closure stresses in excess of 5,000 psi. Conductivity of fractures is further enhanced by forming a pack of the composites in the fracture. |

Optimized salinity for enhanced water flood applications
Methods for enhanced oil recovery from subterranean formations by treating a produced water prior to injection into the subterranean hydrocarbon reservoir and manipulating produced water compositions to increase the rate and/or amount of oil that is recovered from producing wells and/or a hydrocarbon reservoir. The treatment of the produced water can increase the pH of the water from about 0.75 to about 2.0. |

Aqueous ink
The present invention relates to a water-based ink containing at least pigment-containing water-insoluble crosslinked polymer particles (A), a polymer emulsion (B) and water, in which a water-insoluble crosslinked polymer constituting the crosslinked polymer particles (A) is obtained by subjecting a polymer that contains a constitutional unit derived from a carboxylic acid monomer having an acid value of not less than 200 mgKOH/g and a constitutional unit derived from a hydrophobic monomer, to crosslinking reaction with an epoxy compound, and a polymer constituting the polymer emulsion (B) contains a constitutional unit derived from a carboxylic acid monomer and a constitutional unit derived from a hydrophobic monomer. The water-based ink of the present invention is excellent in ejection stability and fastness of the printed characters or images while maintaining good optical density. |

Waterborne inorganic anti-doodling ceramic paint for indoor walls and preparation method therefor
The present disclosure discloses a waterborne inorganic anti-doodling ceramic paint for indoor walls and preparation method thereof; the ceramic paint is a dual-coating paint having an under-coating paint and a surface-coating paint. The advantage effects of the present disclosure is that: the main film-forming materials are inorganic materials, the solvent is mostly deionized water, VOC emission is extremely low, thereby having a characteristics of safety, health and environmental protection; overcoming the shortcomings of multi-components of ceramic paint needs to be aged before use, while the under-coating paint and the surface-coating paint of the present disclosure are all single-component and can be directly used, easily to apply and fast; having an anti-doodling effect, when a marker doodling on the walls, it can be easily erased; the coating has a low surface tension which can isolate the outdoor moisture and prevent the walls from getting wet and mildewed. |
