摘要:
Provided in the disclosure is a pre-stressed concrete track slab of slab-type ballast-less track, which includes a slab body (1), on which fastening embedded casings (4) are arranged. At least one row of longitudinal common steel bars (11) and at least one row of transverse common steel bars (12) are arranged in the slab body (1) along a length direction and a width direction. The longitudinal common steel bars (11) are insulated from the transverse common steel bars (12). At least one row of longitudinal pre-stressed steel bars (7) and at least one row of transverse pre-stressed steel bars (6) are fastened in the slab body (1) along the length direction and the width direction through anchor backing plates and fastener devices (8). In the pre-stress directions of the longitudinal pre-stressed steel bars (7) and the transverse pre-stressed steel bars (6), it is post-tensioned in both directions or it is pre-tensioned in one direction and post-tensioned in the other direction. Limiting structures (5) and grounding terminals (10) are also arranged on the slab body (1). The pre-stressed concrete track slab has the characteristics of light structural dead weight, small structure height, low manufacturing cost and deformation resistance.

A ballastless track system comprises a base; a track slab arranged above the base; a poured-field layer arranged between the base and the track slab, the poured-field layer being formed by filling self-compacting concrete, emulsified asphalt cement mortar or resin mortar, and the inside of the poured-field layer being of a steel bar structure; a connecting piece, the first end of the connecting piece extending into the track slab, and the second end of the connecting piece extending into the poured-field layer; and two rows of rail-seat arranged on the track slab in parallel; and rails arranged on the rail-seat. The ballastless track system is high in reliability, good in durability, and easy in construction and maintenance.

A multi-entry socket power delivery structure is attachable to a printed circuit board to provide improved delivery of one or more power supply signals to a socket. The power delivery structure provides an additional path for power supply signals to be delivered to a socket (in addition to the “power corridor” of the printed circuit board). The power delivery structure comprises one or more portions, with individual portions comprising a printed circuit board connection portion that attaches to the printed circuit board to receive a power supply signal generated by a voltage regulator, and a socket connection portion that attaches to the printed circuit board to deliver the power supply signal to the socket via the printed circuit board. The power delivery structure can be located in the recess of a reinforced backplate that provides structural integrity to a processor stack and associated thermal management solution loading mechanism.

Forming a two-dimensional polymeric sheet includes translating a portion of a flexible substrate through a first liquid precursor to coat the portion of the flexible substrate with the first liquid precursor, thereby yielding a precursor-coated portion of the flexible substrate. The precursor-coated portion of the flexible substrate is translated through an interface between the first liquid precursor and a second liquid precursor, thereby reacting the first liquid precursor on the precursor-coated portion of the flexible substrate with the second liquid precursor to yield a polymer-coated portion of the flexible substrate.
摘要:
The present invention discloses a pharmaceutical composition that includes rivaroxaban and one or more excipient in a solid dosage form and methods for making the same. Methods for making compositions of the present invention includes powderizing rivaroxaban by centrifugal wet granulation to form compositions suitable for solid oral dosage form. Pharmaceutical dosage forms produced by methods of the present invention are more homogenous, smoother, and have better rheological properties, better compressibility, and much easier to make. They are much lower in cost and also easier to produce at industrial scales.

An image converter receives a two-dimensional image to be converted to a first three-dimensional image. The image converter identifies a feature-to-depth mapping function associated with a second three-dimensional image in a data store. The second three-dimensional image shares a characteristic with the two-dimensional image. The image converter determines a depth value for a plurality of pixels of the two-dimensional image according to the feature-to-depth mapping function and generates the first three-dimensional image based on the depth value for the plurality of pixels of the two-dimensional image.

Techniques described herein enable better understanding of the intent of a user that submits a particular search query. These techniques receive a search request for images associated with a particular query. In response, the techniques determine images that are associated with the query, as well as other keywords that are associated with these images. The techniques then cluster, for each set of images associated with one of these keywords, the set of images into multiple groups. The techniques then rank the images and determine a representative image of each cluster. Finally, the tools suggest, to the user that submitted the query, to refine the search based on user selection of a keyword and a representative image. Thus, the techniques better understand the user's intent by allowing the user to refine the search based on another keyword and based on an image on which the user wishes to focus the search.
摘要:
An image converter receives a two-dimensional image to be converted to a first three-dimensional image. The image converter computes a feature-to-depth mapping function based on an approximate depth map associated with a second three-dimensional image. The image converter applies the feature-to-depth mapping function to a plurality of pixels of the two-dimensional image to determine a depth value for each of the plurality of pixels and generates the first three-dimensional image based on the depth values for the plurality of pixels of the two-dimensional image.
