Abstract: A preparation method and an application of a tailings-based zeolite@carbon dots-titanium dioxide (CDs-TiO2) composite photocatalyst are provided, which relates to the field of solid waste utilization technologies. The preparation method includes performing an acidification treatment on tailings powder and then roasting to obtain modified tailings powder; adding the modified tailings powder and titanium dioxide into lye to obtain mixed suspension; stirring and aging the mixed suspension under ultraviolet irradiation to obtain an aged suspension, performing a hydrothermal reaction on the aged suspension to obtain a product, filtering, washing and drying the product to obtain the tailings-based zeolite@CDs-TiO2 composite photocatalyst.

Abstract: The present invention discloses a 400 MPa corrosion-resistant steel bar and a production method thereof. The steel bar includes the following chemical ingredients: 9.5-10.4% of Cr, 1.0-1.2% of Mo, 0.3-0.6% of Mn, 0.01-1% of Ni, 0.01-0.5% of Cu, at most 0.014% of C, at most 0.004% of N, 0.01-0.05% of Nb, 0.2-0.6% of Si, and the balance of Fe, where Cr+Mo+0.5Mn+0.35Ni+0.25Cu is 11.1-12.2%, and C+N+0.3Si+Mn+1.8Nb is 0.4-0.8%.

Abstract: Smart vehicle parking apparatus and related methods are disclosed herein. An example system includes a processor to reserve a personal vehicle for a time interval. The personal vehicle is to park at a location during the time interval. The processor is also to match a vehicle use option to the personal vehicle based on the time interval and the location. The vehicle use option is associated with a person to use the personal vehicle during the time interval.

Abstract: Systems and methods interacting with a digital map are provided herein. A system includes a display that is configured to display a digital map. The digital map includes a number of targets with which a user can interact and a number of actions that are available for each target. The system is configured to update a table of an individual profile account when the user performs an actions at one of the targets, use a role prediction model to predict a role based on the table of the individual profile account, and update the table of the individual account based on a table of a role profile account associated with the predicted role.

Abstract: Systems and methods interacting with tabletop models using a handheld device are provided herein. A display system includes a tabletop model, including a horizontal display that is configured to display a two-dimensional digital map and a three-dimensional physical model that is configured to overlay the two-dimensional digital map. The display system includes a mobile device including a touchscreen display. The display system transforms a movement on the touchscreen display to a movement of a cursor on the two-dimensional digital map.

Abstract: An apparatus includes a processor configured to send detour instructions defining a travel path that avoids a location of the traffic event. The detour instructions may be sent responsive to receiving notification of a traffic event. The processor is further configured to update the detour instructions to alter the travel path based on the proposed vehicle routes such that autonomous vehicles operate to follow the altered travel path. The update may be responsive to proposed vehicle routes different than the travel path received from vehicles in a vicinity of the location.
