Abstract: A multi-layer federated learning method based on distributed clustering is provided, which comprises the following steps. Computing a feature distribution similarity for each of participating nodes with non-(non-independent and identically distributed) data sets, and grouping these nodes into plural clusters by the feature distribution similarity. Updating local model of nodes of each cluster by a federated learning algorithm, and inputting these nodes into a multi-layer aggregation mechanism. Terminating the operation of the multi-layer aggregation mechanism until the clustering result meets a required demand. Furthermore, we implement a blockchain-based multi-layer federated learning system, including model aggregation module, API module, time-series synchronization module, and IPFS, based on distributed clustering architecture. The learning performance is proven to effectively improved.

Abstract: An image authentication method and a real-time product authentication system are provided. The method includes the following steps: inputting a training image in a training phase; segmenting the training image into a plurality of training sub-images; and training the deep learning model by using the plurality of training sub-images, wherein each of the plurality of training images includes a global feature property. The steps in the testing phase include: inputting a testing image and segmenting the testing image into a plurality of testing sub-images; performing a test on each of the plurality of testing sub-images and checking whether each of the plurality of testing sub-images is associated with one of the plurality of categories; and outputting an authentication result to identify whether the testing image is associated with one of the plurality of categories.

Abstract: A hearing training device, is provided, including: a wearable device configured for being worn on the head of a user; a playing device arranged on the wearable device; an acupoint stimulation device, served as a physiotherapy device, comprising a plurality of acupoint stimulation mediums arranged on the wearable device, respectively configured for stimulating a plurality of acupoints on the head of the user and related to hearing, and arranged at the positions of the wearable device corresponding to the acupoints respectively; and a control device being in signal connection with the playing device and storing at least one music file, wherein the control device controls the playing device to play the music file, a beat is formed in an audio track of the music file, and the beat decreases with time, and is fixed until the beat is between 10 Hz and 15 Hz.

Abstract: A sitting type spinal traction and disc massage apparatus includes a seat member, a seat pad disposed atop the seat member, a fixing member straddling the seat member and the seat pad and connected to the seat member to fix hips of a user to the seat member, and a moving backrest board disposed atop a rear end of the seat member. The moving backrest board is movable relative to the seat member. A restricting member straddles and is connected to the moving backrest board to fix the user's upper body to the moving backrest board. A lifting unit is disposed below the moving backrest board to move the moving backrest board upwardly from the seat member to stretch the user's spine. A vibrating unit is disposed within and vibrates the seat pad.

Abstract: Provided is a method for manufacturing cell-containing blocks having steps of: preparing an standardized size mold by 3D printing (three dimensional printing) using a biocompatible elastic material; injecting a thermosensitive colloid into the mold to form a thermosensitive mold; injecting a hydrogel containing cells in to the thermosensitive mold and curing the hydrogel containing cells to form the cell-containing blocks; separating the thermosensitive mold and the cell-containing blocks at a temperature higher than a solidifying point of the thermosensitive colloid. Also provided are method for assembling the cell-containing blocks in a target configuration by using an assembling mold defining the target configuration and made of a thermoreversible material.

Abstract: A joint mobilization apparatus includes a pulling unit and a power unit. The pulling unit includes a wearable member set for mounting on the patient's joint part, and a rope set connected to the wearable member set. The power unit provides power of reciprocatingly pulling the rope set, and includes a shell member, a motor, and a reciprocation mechanism connected to the motor and the rope set. The reciprocation mechanism is driven by the motor to reciprocate relative to the shell member, so as to pull the rope set to reciprocate the wearable member set and patient's joint part. By using the power unit to drive the pulling unit to pull reciprocatingly for mobilizing the patient's joint part, instead of the therapist's treatment, the therapist's burden in physical strength can be reduced. Furthermore, the joint mobilization apparatus can provide the user to execute various muscle training modes.

Abstract: A system for training visual acuity includes an audio player and a controller. The audio player includes a database which stores plural pieces of music, and a headphone with which a user listens to the pieces of music so as to stimulate a visual cortex of the user, where each of the pieces of music contains two audio frequency components that have a frequency difference therebetween ranging from 1 to 45 Hz. The controller is electrically connected to the audio player, and is configured to control the audio player to play the pieces of music.

Abstract: A CBR-based negotiation RBAC method for ubiquitous resources management is described. The method, which is applicable to serving servers, includes steps of inquiring for a similar case in a case base in order to obtain an initial case, performing a REUSE procedure or a REVISE negotiating procedure on the initial case to assign at least one appropriate role set consisting of a local role and a virtual role, performing a local role and virtual role fitting procedure to fit the local role and the virtual role, and performing a determining and retaining procedure to meet the requirements of users during the negotiation process.
