Abstract: An construction method of an embryonic chromosome signal library is provided. The construction method comprises obtaining an embryo and performing whole-genome amplification and next-generation sequencing to obtain a first chromosome signal; mapping the first chromosome signal to a chromosome reference signal to obtain a second chromosome signal; dividing the second chromosome signal within a predetermined interval range to obtain a third chromosome signal; and performing a regression correction on the sequencing read count (RC) of the third chromosome signal to obtain an embryonic chromosome signal library. Furthermore, a detection method and system of embryonic chromosomes are also provided. Thereby, the information comparison of the embryo chromosome signal library is used to determine whether the pre-implantation embryo is abnormal or not to achieve pre-implantation chromosome screening of pre-implantation embryos.

Abstract: A replay device and method thereof with automatic sentence segmentation is provided. A soundwave analysis module receives a soundwave signal and analyzes the soundwave signal to determine plural segmentation points. A replay actuation module receives a replay command and sets a replay endpoint on the soundwave signal. A replay access module sets the nearest segmentation point prior to the replay endpoint as a replay startpoint. A replay module plays the soundwave signal from the replay startpoint to the replay endpoint.

Abstract: A method for varying speech speed is provided. The method includes the following steps: receive an original speech signal; calculate a pitch period of the original speech signal; define search ranges according to the pitch period; find a maximum within each of the search ranges of the original speech signal; divide the original speech signal into speech sections according to the maxima; obtain a speed-varied speech signal by applying a speed-varying algorithm to each speech section of the original speed signal according to a speed-varying command; and eventually, output the speed-varied speech signal.

Abstract: A device and method for evaluating learning including a level examining module, a course planning module and a course evaluation module are provided. The level examining module provides a level examination for a user to determine a current capability level of the user. The course planning module plans a learning course for the use according to the current capability level as determined by the level examining module. The course evaluation module generates an evaluation quiz according to the learning course. After the user finishes the evaluation quiz, the course evaluation module also generates learning information to evaluate the user's learning status.

Abstract: A device and method is provided for a user to arrange learning courses. The device comprises: a course database, a capability examining module and a course arranging module. The course database stores multiple learning courses, each including multiple learning quizzes. The capability examining module provides capability examination(s) for the user to determine the user's current capability level. The course arranging module acquires the corresponding learning courses from the course database according to the capability level determined by the capability examining module, and arranges these acquired corresponding learning courses for the user to learn.

Abstract: In an apparatus and a method for automatically indicating time in a text file, a receiver module receives a text file and a speech file, in which the text file is composed of a plurality of sentences; a speech recognition module transforms the sentences in the text file into a speech model, divides the speech file into a plurality of sound frames and assigns numbers to them in sequence in accordance with a time interval, turns speech data of the sound frames into feature parameters through speech capturing, and calculates the best speech route matching the sound frames with the speech model; an indicator module captures the assigned number of the sound frame corresponding to the beginning of each sentence in accordance with the best speech route, obtains a starting time of the speech file corresponding to the beginning of each sentence through the assigned number of the sound frame and a time interval and indicates the starting time in the text file.
