In video-conference, the camera is placed at the top of the screen and the user looks at the other user's image on the screen. This misalignment of eye gaze direction degrades the user's experience. To solve this problem, this paper presents an eye gaze correction method using vertical stereo camera. The proposed method matches the eye regions in two images captured by stereo camera and generates new eye regions by alpha-blending these two eye regions. To obtain a gaze corrected image, we replace eye regions in top image with new eye regions. The proposed method requires fewer computations than conventional methods using stereo camera. Experiment results showed that the proposed method could generate eye gaze corrected images at 14 frames per second using images captured simultaneously by top and bottom cameras with the resolution of 640×480.

This paper presents a new framework that enables the remote monitoring of solid waste bin in real time, via ZigBee-PRO and GPRS, to assist the solid waste management process. The system is designed to monitor the status of the bin as soon as someone throw waste insight it. The system framework is based on a wireless sensor network, contains three levels: smart bin, gateway and control station that stores and analyze the data for further use. In this way, the waste collection route can be optimized by feeding the collected data into a decision support system and hence able to reduce operation costs and emissions.

ITU-T has identified context awareness as a key capability for providing “smartness” in Smart Ubiquitous Networks (SUN). Based on standardization activity for SUN, this paper introduces context awareness for SUN, including functional model and operations as challenges for various networking capabilities using context awareness. It aims to stimulate the development of standards and urgent technical solutions through related research work for SUN as an early realization of Future Networks.

We propose a new method for full-duplex self-interference cancellation. The proposed scheme uses a precoder to align the self-interference channel with orthogonal direction of detection axis. The simulation result shows that the proposed RP-SIC enhances the average throughput of user equipment compared to the conventional scheme in high residual self-interference region.

Resistive switching random access memory (ReRAM) is strong candidate for future non-volatile memories due to its high density integration, long retention time, and fast switching speed. A two-terminal passive array of crossbar frameworks consists of a set of electrically resistive switching (RS) elements which is sandwiched between perpendicular bottom and top electrodes. RS can be classified into two types (unipolar, and bipolar RS) based on electric polarity dependence on the sign of the applied voltage. To obtain two stable resistance states, namely, high resistance state (HRS) and low resistance state (LRS), it is applied `Set' bias to switch from HRS to LRS, and `Reset' bias from LRS to HRS. RS that could be accomplished without changing the bias polarity is called unipolar RS (URS). On the contrary, opposite polarities are required for bipolar RS (BRS). Recently, there were report about the improvement on endurance and data retention of an Au/Si3N4/Ti cell by hydrogen-post-annealing.

Tracking in cluttered environments requires false track discrimination and data association. We extend the particle filter approach to include the data association probabilities and recursively calculate the probability of target existence. The probability of target existence may be used to discriminate false tracks.

This paper proposes a randomized variable probability pattern in under-sampling acquisition for medical image matching which is a method that can perform the quantitative analysis of tissue parameters. For high-speed estimation of tissue parameters, random under-sampling with less than the Nyquist rate in k-space is required. This study presents an accurate parameter mapping method for under-sampled data by using various randomized probability pattern. In comparison to the fixed probability pattern, the proposed method shows improved estimation results with reduced artifacts such as ghosting effects due to the undersampling scheme.

An ultra-low power multi-rate FSK transmitter implemented in 0.18 μm CMOS process is presented. A digital frequency interpolator is adopted in the transmitter for achieving multiple data rate transmission. Power consumption of the transmitter is dependent on the required transmitted data rate. Thus, high power efficiency can be achieved. As applying for implantable or wearable biomedical devices, the feature of high power efficiency leads to a great improvement of lift time of the implantable or wearable biomedical devices. Moreover, all transistors of the transmitter are operated under sub-threshold region for realizing ultra-low power consumption. The transmitter consumes 378 μW to 424 μW according to the transmitted data rate varying from 200 kb/s to 2 Mb/s under a supply voltage of 0.7 V. Therefore, minimum energy consumption per transmitted bit of 212 pJ/bit can be achieved under the maximum transmitted data rate of 2 Mb/s.
