The invention discloses an urban road network travel time estimation method based on adaptive multi-task deep learning and belongs to the technical field of intelligent transportation. Firstly, features affecting the travel time of a road segment are extracted, then a deep network formed by multiple feature learning layers is constructed with a noise reduction sparse self-encoder as a component, and the feature representation of input is learned layer by layer. Finally, a probability-based method is used to carry out modeling on the uncertainty of the travel time, a multi-task regression layeris constructed, an error from an observation value is outputted by a minimized model, and thus the model automatically adjusts the weight of each task. According to the method, an existing method hasthe defects that a shallow network is difficult to describe a complex non-linear travel time in an urban road network, the manual adjustment of the weight of a joint learning task and only data witha complete task tag can be used are overcome, the efficiency of travel time estimation is improved, and the method has an important practical significance in the estimation of the travel time of the urban road network.

The invention belongs to the traditional Chinese medicine field, and in particular relates to a traditional Chinese medicine for treating impotence and a method for making the same. The traditional Chinese medicine is mainly made by processing and refining velvet antler, epimedium herb, twotooth achyranthes root, ginseng, astragalus root, angelica and lyophilized royal jelly. The medicines in compatibility bring out the best in each other, jointly guarantee the efficacy of warming Yang and nourishing kidney, and play a significant role in warming kidney and strengthening Yang. Moreover, the traditional Chinese medicine has the advantages of good clinical efficacy, fast effect, short treatment course, no obvious toxic and side effect, etc., which is a good medicine for treating impotence.

The invention relates to an automatic grading and screening equipment for fruit particles, which includes a bottom plate, a conveyor, a connecting bracket, a holding mechanism, a vertical plate, a screening mechanism and a collection frame. A conveyor is distributed above the bottom plate, and the conveyor passes through the bottom of the bottom plate. There are brackets installed on the top of the bottom plate, connecting brackets are evenly installed on the conveyor, and a holding mechanism is installed on the top of each connecting bracket, the erecting plate is located in the conveyor, the erecting plate is installed on the top of the bottom plate, erect The top of the plate is uniformly equipped with screening mechanisms along its length. The present invention can solve the following problems existing in the existing fruit screening: the position of the fruit cannot be positioned, causing the hidden danger of the fruit slipping, and the hidden danger that the rotating plate on which the fruit is placed cannot be rotated at a large angle, causing the fruit to be stuck on the rotating plate Due to the above phenomenon, the weight of fruit screening cannot be adjusted quickly.

The invention provides a movable road flag which comprises a base, two supporting barrels arranged on the base, a connecting piece connected between the two supporting barrels, flag rods inserted into the supporting barrels and flags arranged on the flag rods. The base comprises a hollow base body and sand contained in the hollow base body. The hollow base body is provided with a sand inlet and a sand outlet. A plug body is arranged at the sand outlet. The two supporting barrels are oppositely arranged. Each supporting barrel comprises a vertical section and an inclined section which is inclined and extended from the top end of the vertical section to be away from the other supporting barrel. The connecting piece comprises two positioning pieces fixing the supporting barrels and a screw connected between the two positioning pieces. Each positioning piece comprises a sleeve body where the corresponding supporting barrel penetrates, and an extending portion extending outwards from one side of the sleeve body. The screw penetrates through the extending portions of the two positioning pieces and is fixed with a nut. According to the movable road flag, the sand amount in the base can be controlled according to practical requirements, the weight of the base is adjusted, and therefore both moving convenient and using stability are achieved.

The invention provides an adaptive conveying device, which includes a fixing device for supporting the entire conveying device, the fixing device includes a bottom plate, the top of the bottom plate is uniformly arranged with bottom balls, and the top of the bottom ball A crawler conveying device is supported, and the bottom ball is limited and fixed on the bottom area of ​​the bottom plate through a limit baffle structure; the periphery of the crawler conveying device is provided with a power device casing for its protection. The device can be used to change the transportation surface shape, transportation length, width, and transportation speed of the transportation device within a certain range, so as to improve the adaptability of the transportation device to the weight, volume, transportation terrain, slope and transportation distance of the transportation device.
