Pre-term infants often suffered from immature lung development, which caused oxygen saturation (SpO2) to be fewer than 90% (98-100% for normal infants). Oxygen therapy was an essential treatment - supply right proportional air-oxygen gas content called a fractional of inspired oxygen (FiO2) via nasal cannula - to control SpO2 in a range of 90-95% and to maintain life. Registered nurses (RN) were routinely responsible for adjusting FiO2 between 21-100% according to a current SpO2 and a doctor's order. The objective was to supply FiO2 as low as possible while maintaining SpO2 in a suitable range. However, manual adjustments were not in real time (normal every 20-30 minutes) which could introduce risk of either oxygen toxicity from too high SpO2 or hypoxia from too low SpO2. This research was to develop an automatically control of FiO2 according to an order SpO2 by medical doctors. The result of this research could reduce risk of blindness from oxygen toxicity as well as mortality from hypoxia in pre-term infants. The system also allowed medical doctors to use recorded data for future care plan in oxygen therapy. This research introduced two different algorithms for such purposes and described a design of such system.

This work proposes an automatic recognition system for recognizing audio events. First, an audio signal is converted into a spectrogram by short time Fourier transform. The acoustic background noises in the spectrogram are reduced by box filtering. The contrast of the spectrogram is then enhanced by VAR operation. With the enhanced spectrogram, this work further proposes a novel dynamic local binary pattern (DLBP) feature based on human auditory system. Finally, the DLBP features are fed to multi-class support vector machines to achieve the audio event recognition. The experimental results on 16 classes of audio events demonstrate the performance of the proposed audio event recognition system.

Wireless body area sensor network (WBASN) implements realtime health monitoring by outfitting patients with wireless vital sign sensors. This paper presents an aplication that can assist doctors/nurses to monitor any changes in the position of the patient; they do not need to see the patient directly. They can monitor the patient position at other room of the patient. This aplication can shows any changes in the patient's position in realtime.

High-energy radiation beam is used in radiotherapy to kill the pre-located cancerous cells. No matter how accurately the body is positioned, or which of the chest or abdominal breathing method is used, the cancerous site often moves with the breath. Such motion artifact is an unpredictable factor during the radiotherapy, and introduces risks in damaging surrounding normal tissue. Our previous study focused on recording the motion from abdominal breathing only. In this work we find appropriate locations to place landmarks, and integrate multiple cameras to record and trace both breathing patterns. When watching the real-time video of motion artifact, patients can control their breath depth to fit the record taken when they receive imaging check to locate cancerous area. The system can lower the risk and improve the efficacy of radiotherapy.

Depth-image-based rendering (DIBR) produces multiple views efficiently. However, its process lacks some viewpoint information. There will be holes, which influences the 3D video quality. Previous DIBR techniques were mainly applied to 3D images, so it only relied on the single view and the depth map to fill the holes, but insufficient repair information resulted in incorrect repair. In this paper, we aim to repair 3D videos by the hole filling for DIBR, which introduces the relation between frames to increase the repair information. We apply the moving behavior and the texture similarity within interframes to assure the accuracy of the repair information. The experiment results demonstrate that compared to previous methods, the proposed method obtain better 3D video quality. The average peak signal-to-noise ratio (PSNR) increases by 1.014 dB, and the structural similarity (SSIM) index increases by 0.012, which shows that the proposed method obtains better quality than the methods that only apply the single view image information.

In the paper, a novel ontology-based recommendation model based on a fuzzy-rough hybrid mechanism is proposed. This model integrates the principles of both content-based and collaborative filtering recommender systems. The proposed model unified user profile/item characteristics profile representations in a concept level space. Hence not only the user preferences and the correlation between items, but also the information of other users with similar preferences can be used for more precise recommendation.

In this paper we propose an improvement design to integrate a combination of both a smartphone and a projector to reduce uncomfortable light emitting from a digital projector. The smartphone executes the face detection module, and superimposes the black mask in the position of the face to reduce all uncomfortable light shining in the speaker's eye. This design uses the skin color detection and background subtraction methods to increase the face recognition rate of the previous design. In addition, this design also provides the face detection method for multiple users, so that the projector simultaneously places multiple black masks, and each mask is superimposed for each user's face.

The backlight power saving for LCD is an important research topic, since the backlight is the main source of energy consumption. Typically, the backlight power saving is done by limiting the dynamic range of the displayed pixels; the image quality will decreased. And how to maintain the image quality becomes the important issue. In this work, we propose to use a well-known video quality metric called VQM (Video Quality Metric) to measure the video quality, and proposed a VQM curve to be predicted by the MSE (Mean Square Error). This proposed curve can later be used to efficiently maintain the video quality while performing the backlight power saving.

This research involves a simple and high concentration simulation design for a passive solar lighting system. This system incorporates the technology and optical design that are required for the collection and emission of sunlight for solar lighting. Several pieces of Plano-convex lens are placed in a specific geometric arrangement, so that without a solar tracking system, parallel light emitted by the sun at different times can be collected. The light can then be focused via lenses and internally transmitted through optical fibers and ultimately be transmitted to the emission element. This system is expected to be used as a reference for sufficient lighting for indoor rooms and toilets in a building whether in the morning or afternoon on a sunny day.
