7results about How to "Balance cost" patented technology

This application provides a method for recommending travel routes, an in-vehicle system, and a storage medium, relating to the field of in-vehicle tourism service technology. The method can obtain the route length, travel time, required travel cost, and average experience score of all attractions for each travel route. Then, for each travel route, it determines a first sub-rating corresponding to the route length, a second sub-rating corresponding to the travel time, a third sub-rating corresponding to the travel cost, and a fourth sub-rating corresponding to the average experience score. A weighted average of the first, second, third, and fourth sub-ratings for each travel route is taken to obtain a recommended rating for each travel route. Based on the top N% of travel routes ranked by their recommended ratings, recommended routes are output, which can balance short route length, short travel time, low travel cost, and high average experience score, achieving a balance between the user's itinerary, travel time, cost, and overall experience.

This invention achieves an optimal balance between cost and performance through the wear-resistant design of the flow-facing edge, significantly extending the service life of the agitator blade in high-solids-content media, and substantially reducing equipment maintenance frequency and related costs. It demonstrates significant technological advancement and social and economic benefits.

This invention discloses a lightweight image super-resolution reconstruction method, system, and storage medium, relating to the field of image processing technology. Specifically, it includes: acquiring high-resolution and low-resolution images of the target as training sample pairs; constructing a lightweight image super-resolution reconstruction model comprising a shallow feature extraction module, a deep feature extraction module, a multi-layer feature fusion module, and an image reconstruction module. The shallow feature extraction module performs shallow processing on the low-resolution image; the deep feature extraction module consists of multiple cascaded enhanced separable residual feature refinement blocks, extracting shallow features to obtain multiple deep features; the multi-layer feature fusion module is used to obtain fused features; and the image reconstruction module is used to output the high-resolution image. The trained model is used to reconstruct the low-resolution image to be processed. This invention has a simple network structure and achieves accurate reconstruction of image texture and details using only a low number of parameters and computational cost.

This solution discloses a portable vegetation capsule method for vegetation restoration on rocky slopes, applicable to the field of ecological restoration engineering technology. The method includes five steps: manual slope clearing, preparation of a water-collecting and water-retaining granule-sowing mixture, excavation of planting holes, planting in the vegetation capsules, and post-planting maintenance. Water-collecting and water-retaining granules, native tree, shrub, and grass seeds, and slow-release granular fertilizer are mixed in a precise ratio, filled into biodegradable vegetation capsules, and then planted manually in the gravelly soil area of ​​the rocky slope. The water-collecting and water-retaining granules expand upon contact with water, forming a sticky fibrous covering layer, which enhances seed adhesion, resists wind and rain erosion, and continuously supplies moisture. This invention is suitable for rocky slopes with a slope of ≤30°, and has the advantages of minimal slope disturbance, convenient construction, low cost, and high vegetation survival rate, effectively achieving ecological restoration and soil and water conservation on rocky slopes.
