    摘要： A method for improving the effectiveness of a building air circulation system having motorized blower and a contamination filter. The method including predicting a cost of operation of the system over an operational duration based on at least electricity consumption of the motor (115), and an operational cost to operate the filter (148), predicting a cost of maintenance of the system over the operational duration based on at least one of, a condition of the filter (148), a cost of a filter (148), a cost of labor to clean or replace the filter (148), and an effectiveness of the filter (148) over the operational duration, and balancing the cost of operation of the circulation system versus the cost of maintenance of the circulation system over the duration to recommend at least one of a filter use/bypass schedule, a filter maintenance schedule, and a fresh air input schedule satisfying an operation objective and an operational constraint.

    摘要： Systems and methods are provided for scoring non-native, spontaneous speech. A spontaneous speech sample is received, where the sample is of spontaneous speech spoken by a non-native speaker. Automatic speech recognition is performed on the sample using an automatic speech recognition system to generate a transcript of the sample, where a speech recognizer metric is determined by the automatic speech recognition system. A word accuracy rate estimate is determined for the transcript of the sample generated by the automatic speech recognition system based on the speech recognizer metric. The spontaneous speech sample is scored using a preferred scoring model when the word accuracy rate estimate satisfies a threshold, and the spontaneous speech sample is scored using an alternate scoring model when the word accuracy rate estimate fails to satisfy the threshold.

    摘要： A mobile electronic device and a sound playback method thereof are provided. The mobile electronic device includes a sensor, a speaker, and a controller coupled to the sensor and the speaker. The sensor detects whether the speaker is blocked or not. When the speaker is blocked, the controller multiplies a sound signal by a transfer function and then outputs the multiplied sound signal. The speaker plays the sound signal outputted by the controller. The transfer function changes the direction in which the speaker plays the sound signal.

    摘要： Provided herein is a method for detecting landing quality of an aircraft. Method steps include using an aircraft data system to determine whether a vertical speed rate is greater than a first preset value when the aircraft lands; determine whether a vertical acceleration is greater than a second preset value if the vertical speed rate is not greater than the first preset value when the aircraft lands; collect landing data; generate a landing message based on the collected landing data; store or transmit the landing message; and determine the landing quality based on the landing data in the landing message.
