Abstract: Provided is a plant operation support apparatus including a plant simulator, a predictor, and a predicted KPI deriver. The plant simulator simulates a state at a current time or a predetermined time of a plant based on information obtained from the plant, to output an estimated value at the current time or the predetermined time of process data in the plant. The predictor predicts a state at a predetermined future time of the plant based on the estimated value and outputs a predicted value of the process data in the plant. The predicted KPI deriver derives a predicted KPI which is an index for monitoring the state at the future time of a task to be monitored in plant operation based on the predicted value.

Abstract: Provided are a fuel placement confirmation method and a fuel placement confirmation apparatus that can increase an underwater imaging distance, collectively image a wide region, and reliably confirm an imprint number of a fuel assembly in consideration of a water fluctuation.

Abstract: Since an investigation apparatus is connected through a cable and is remotely operated, the cable may be caught by an obstacle, thereby limiting a movement range of the investigation apparatus. An investigation system 15 includes an investigation apparatus 50 which moves to a position where an investigation target is investigated, by using a traveling section 51 and a support apparatus 30 which moves to a position where letting-off and winding of a cable 14 for an investigation apparatus which is connected to the investigation apparatus 50 are performed, by using a traveling section 31. The investigation apparatus 50 outputs an image of the investigation target which is captured by a camera section 53, to an investigation apparatus controller 40 via the cable 14 for an investigation apparatus.

Abstract: To play back a content while managing the right of use of the content, such as a total time of playback of the content, an electronic device stores right information in a right temporary storage unit 59 and judges whether or not use of the content is permitted, in a process of decoding a frame. Also, the electronic device updates the right information stored in the right temporary storage unit 59. When the frame to be played back is the one at a predetermined position in order, the electronic device stores the right information stored in the right temporary storage unit 59 into a storage area 20.

Abstract: Upon receipt of a music signal from a music-signal input section, a sound-source separating section in a preprocessing section separates the music signal into a plurality of signals in units of the type of audio source. A physical-property converting section changes a physical property of each of the signals on the basis of control information received from a control-information input section. A signal-synthesizing section synthesizes a plurality of output signals outputted from the physical-property converting section, and supplies the resultant signal to a data-compressing section. For example, in compressed data, a high data rate is allocated to a vocal, whereas low data rates are allocated to other parts. As a result, quality improvement can be implemented in auditory perceptibility of a musically important part.
