To access the plentiful cloud services in cloud computing, data packets of diverse cloud applications are transmitted via the reliable end-to-end TCP or the unreliable UDP protocol. However, the reliable cloud transmissions suffer from wireless high-interference and high packet loss rate in heterogeneous wireless networks. Thus, an efficient cross-layer-based mechanism if proposed herein to differentiate whether a loss event is caused by the wired network congestion or by the wireless radio interference. Moreover, to analyze TCP four states probabilities of the adaptive TCP approach, a Markov chain-based analytical model is proposed. The proposed approach and several important congestion controls are evaluated under different impact factors, and the proposed approach outperforms other TCP approaches in goodput and yields competitive fairness.

This paper presents a binocular eye tracking device which used 2-D regression-based method to avoid the complicated vector calculations, often applied in geometry-based 3-D tracking, to increase processing speed. It is probably due to the speed increasing that enables us to do the experiments of dynamic estimation errors, which are actually like an experiment to trace a moving object in real 3-D environment if the predefined points, used for evaluating the error estimation, increased to a large number. So far, the preliminary estimations seemed acceptable. It also found 3-D estimation errors mainly caused by the 2-D calibration errors. Therefore, seeking a better 2-D calibration would become one of the important issues for further experiments.

Sub-surface information during a laparoscopic surgery is captured with a near infrared imaging where the tissue is highlighted with the help of an indocyanine dye injected to the patient before the surgery. The surgeons can use such system during the surgery, however, they need to swap the light source between infra-red and the white light to complete the surgery. Swapping the light source causes inconvenience and increase in the time of the surgery. The current study aims to develop a method for superimposing and tracking the infrared imagery on the laparoscopic video acquired under white light. In this study, the infrared imagery was captured and registered to one of the white light imagery from the endoscope video using a 2D image registration technique. The registration technique was based on maximization of mutual information between two images. The edges on the registered infrared image was detected using canny edge detection algorithm. A homography matrix between consecutive video frames under white light was calculated after characteristic feature point detection and matching. The homography matrix was applied on the registered infrared image (only edge) and a new registered edge image was generated. The process continued for every new frame of the video under white light. The system was applied with a video acquisition rate of 20 frames per second. The system needs to be evaluated for its influence on the time of surgery.

In part I of a three-part series on active surveillance using depth-sensing technology, this paper proposes an algorithm to identify outdoor intrusion activities by monitoring skeletal positions from Microsoft Kinect sensor in real-time. This algorithm implements three techniques to identify a premise intrusion. The first technique observes a boundary line along the wall (or fence) of a surveilled premise for skeletal trespassing detection. The second technique observes the duration of a skeletal object within a region of a surveilled premise for loitering detection. The third technique analyzes the differences in skeletal height to identify wall climbing. Experiment results suggest that the proposed algorithm is able to detect trespassing, loitering and wall climbing at a rate of 70%, 85% and 80% respectively.

The proposed low power object locator platform is introduced and the two versions of sample implementation were built to show the applicability. One is based on the nRF24LE1 module and another is based on the nRF24L01 module. The former suit saves the power consumption and the size is reduced. The latter suit provides the physical verification of implementation during the development stage and acts as the reference design to compare the power consumption. The design of the hired components, interfaces and the usage for the proposed platform is introduced. The experimental results show that the power consumption issue has been overcome successfully.

A compact-size and high-isolation microwave diplexer for system-in-a-package has been proposed. By employing the folded stepped-impedance resonators (SIRs), the overall circuit size can be significant reduced. For demonstration, a diplexer operating at 0.5 GHz and 0.86 GHz with third-order Chebyshev bandpass response has been designed and fabricated with microstrip technology. As a result, the diplexer occupies a small size, i.e., 0.14 λg by 0.12 λg. The measured results are in good agreement with the simulation. The output isolation and out-of-band rejection better than 60 dB are achieved.

This paper describes Cost-Awareness Multicast forwarding (CAM), focus on the transmission cost and the efficient multicast data forward in VANETs. Application of the navigation system, we assume only a central center has the planning path of each vehicle and the current location and speed of the vehicle supported by GPS. Once, the source vehicle need to send data to multicast group vehicles. The speed, rendezvous location information are computed. The multicast tree is created based on these information, considering the forward cost. Then The packets are transferred along the edges of the multicast tree.

The electrostatic-discharge (ESD) protection capability of HV nLDMOS devices with the source-side engineering by a TSMC 0.25μm 60-V is investigated in this paper. It can be found that a pure nLDMOS device has a poor anti-ESD ability (It2 = 1.833A). At the same time, if an nLDMOS was embedded with an SCR npn-(pnp-) arranged type in the drain-side, the corresponding secondary breakdown-current values are promoted 19.4% (24.8%) as comparing with a traditional nLDMOS. Furthermore, if the source discrete methodology is applied for the nLDMOS-embedded SCR npn-(pnp-) arranged type, the maximum secondary breakdown current value are promoted 24.1% (>281.9%). Finally, it can be concluded that a discrete distribution in the source region of a pure nLDMOS will upgrade the anti-ESD capability effectively, and it is especially for the nLDMOS-SCR pnp-arranges type.

This paper investigates the thermal characteristics of region surrounding laser welding keyhole. The thermal characteristics of region surrounding laser keyhole play an important role on the mechanical properties after welding. The welding keyhole produced by laser welding is assumed to be a paraboloid of revolution. The laser beam with Gaussian distribution of intensity irradiates on the keyhole. Considering the phase change at solid-liquid interface, this study utilized the finite difference method to numerically calculate the thermal fields in the solid and liquid region surrounding laser welding keyhole.
