Abstract: Proposed is an operating method of an operating system for power-aware smart aids to navigation. The operating method may be an operating method of an operating system for power-aware smart aids to navigation, including service blocks implemented through a microservice architecture and independently operated in a container environment. The method may include determining an operation mode of the operating system for power-aware smart aids to navigation by using an operating module, based on a power supply state. The method may also include selecting control target service blocks from among the service blocks in the determined operation mode by using the operating module.

Abstract: A computer-implemented method of managing the productivity of fish in a land-based aquafarm through data prediction for each growth period is proposed. The method may include predicting, at a processor, a feed amount input to an aquaculture tank based on aquaculture tank sensing data. The method may also include predicting, at the processor, the growth of fish based on results of the prediction of the input feed amount.

Abstract: The described technology generally relates to a scalable high efficiency video coding (SHVC)-based ultra-high definition (UHD) image data transmission and reception system. The SHVC-based UHD image data transmission and reception system includes an image data collector configured to collect various kinds of image data and additional data of the image data. The system also includes an image data coder configured to code the image data and the additional data by using an HEVC-based scalable video coding scheme, and an image data transmitter configured to transmit at least one of a portion of the coded image data and the coded additional data to a terminal via a communication network.

Abstract: A method for transmitting device indicator data in a network-based AV system is provided. The method for transmitting the device indicator data records device indicator data on a data unit which is used in an AV transmission protocol, and transmits the data unit. Accordingly, the indicator data which changes in real time in a network AV device can be rapidly transmitted to a management platform.

Abstract: Provided herein is a serial flash memory device and precharging method thereof in which a single local bit-line data is sensed in synchronization with a clock. The method includes precharging two or more local bit-lines in synchronization with a first clock; and disprecharging one of the two local bit-lines in synchronization with a second clock and sensing and amplifying data of the other local bit-line. Accordingly, two precharged local bit-lines are not adjacent to each other, thereby eliminating a coupling noise effect. In addition, the time for performing the precharging operation and the sensing operation is easily secured, compared to the prior precharging method in which corresponding local bit-lines are precharged at every clock.

Abstract: The present invention relates to a method and apparatus for detecting STBC-OFDM signals in time-variant channels. The method includes a step of demodulating STBC-OFDM modulation signals into OFDM reception symbols using Fast Fourier Transform (FFT); a step of estimating a frequency response for each sub-channel; an STBC decoding step of calculating decision variables determining the A transmit data symbols that are transmitted during the B OFDM symbol periods for each sub-channel; and a step of determining the transmit data symbols based on the decision variables calculated at the STBC decoding step. In this case, the decision variables are calculated using a linear equation that allows a squared Euclidean distance from OFDM reception symbols, which are demodulated during the B symbol periods, to have a local minimum for each decision variable when the STBC encoding and the frequency responses estimated during the B OFDM symbol periods are applied.
