Abstract: A signal decision equalization method and apparatus are provided. The method includes: obtaining an input signal; determining a decision circuit of the input signal; obtaining a first group of decision thresholds and a first group of equalization expectations of the decision circuit; determining a decision value of the input signal based on the first group of equalization expectations, the first group of decision thresholds, and the input signal, and outputting the decision value; updating, based on the decision value and the input signal, a first equalization expectation that is in the first group of equalization expectations and that corresponds to the decision value to a second equalization expectation to obtain a second group of equalization expectations; and updating at least one decision threshold in the first group of decision thresholds based on the second equalization expectation to obtain a second group of decision thresholds.

Abstract: A non-blind area real-time monitoring and alarming system for an accident on a freeway is provided, which belongs to the field of photoelectric technology and can solve the existing problems in whole journey information monitoring for freeways, such as failure to cover all freeway sections and lack of all-weather and prompt monitoring, and being subject to severe environments such as rain, fog and snow, or conditions such as poor visibility at night. The system includes a distributed sound wave detection fiber-optic cable, a sound wave signal demodulator, a network switch, a workstation, and a monitoring terminal. A fiber-optic sensing network composed of a series of reflection nodes distributed at equal distances is utilized to monitor sound wave signals from traffic accidents efficiently in real time without blind areas, accurately locate a traffic incident by analyzing frequency components, and transmit alarming information in time.

Abstract: Embodiments of the present application relate to a method for recommending information, a system for recommending information, and a computer program product for recommending information. A method for recommending information is provided. The method includes determining a set of specific first users comprising at least one specific first user who complies with a first preset condition, the determination being based on operating behavior information of a set of one or more first users recorded in a system, looking up, in the set of specific first users, targeted specific first users having a similarity to a current user who complies with a second preset condition, and providing recommendation information to the current user based on the operating behavior information of the targeted specific first users.
