Cuff-less blood pressure (BP) estimation using pulse transit time (PTT) is a promising method for long-term BP monitoring. However, state-of-art PTT models are unable to trace the change of pressure baseline in subjects, which limits their application in long-term BP tracking. This study investigated the relationship between the change of pressure baseline and pulse waveform in long-term BP monitoring...
We develop a LSPR platform composed of a nanoplasmonic sensor, a spectrometer, and a motorized stage to achieve multi-point and real-time biosensing. The assay can be done in 1 hour with 60 μL sample requirement.
In the past few years, human activity recognition is an active area of machine learning. The possible applications include daily activity monitoring for elders, exercise and fitness workout assistant systems, life style analysis, etc. In this work, tri-axial accelerometers were worn at the right wrist, left wrist and waist to collect motion data for activity recognition. Three supervised machine learning...
Distributed network technology is a new application of inertial navigation technology. A distributed multi-source navigation system, constituted of a distributed inertial navigation system and a multi-senor configuration, can greatly enhance aircraft survival and reliability. Aiming to design a distributed inertial/star sensor/satellite integrated navigation system, this paper studies the structure...
Butting and inserted pickup layout in MOSFETs leads to substrate resistance shunting effect and serious ESD robustness degradation. This work develops novel layout with external well/ diffusion resistance embedding between the substrate and the grounding terminal in the NMOS transistors. This layout method can greatly enhance ESD performance of the inserted pickup devices. The second breakdown current...
Watching a 360° sports video requires a viewer to continuously select a viewing angle, either through a sequence of mouse clicks or head movements. To relieve the viewer from this 360 piloting task, we propose deep 360 pilot - a deep learning-based agent for piloting through 360° sports videos automatically. At each frame, the agent observes a panoramic image and has the knowledge...
This research is about applying life cycle analysis in evaluations of research and innovation policy, especially for research infrastructures. It focused on gaining insights of management challenges or issues of research infrastructure in Taiwan by using scanning of previous policy documents, interviews and a focus group with stakeholders. The result found that many issues were derived from lacking...
Virtual laboratory helps students' learning of experiment manipulation and scientific concepts before they actually enter the real chemistry laboratory. It also helps reduce the risks in conducting the real chemistry experiments and reduce the cost for chemistry experiment materials. This study developed an educational game "O2 LAB©", on the mobile...
Remote photoplethysmography (rPPG) can be used to measure cardiac activity by detecting the subtle color variation of the human skin tissue using an RGB camera. Recent studies have presented the feasibility and proposed multiple methods to improve the motion robustness for the subject movements. However, enhancing the signal-to-noise ratio (SNR) of the rPPG signal is still an important issue for the...
Sheet music has long been regarded as one of the most effective medias for musicians, music players, and amateurs to communicate with each other. It is also an intuitive way for non-professionals to learn how to play a musical instrument or sing a song. However, not all composers have willingness to share their own sheet music, especially those protected by strict copyright regulations. For amateurs...
The attractiveness of negative capacitance field-effect transistors (NC-FETs) stems from their ability to enable a subthreshold swing (SS) below the 60 mV/decade thermal limit at room temperature — a direct effect of the step-up voltage amplifier behavior of the ferroelectric [1]. This effect has been shown to yield sub-60 mV/dec SS in several Si-based NC-FETs [2-4]; however, as Si-based devices become...
The study applied water mist as the projecting medium and two projectors with different circular polarization in order to present 3D image. The system in this study is miniaturized for higher practicability, and judged the image quality by PSNR analysis.
Due to the advent of the aging society, homecare is more and more important. In this paper, we design and implement the contactless pulse rate measurement method based on the Android smart TV, which allows the user to measure their pulse rate without requiring of contact sensors. This framework provides a convenient measurement environment for homecare. The results of the experiment show the presenting...
Proliferation of the number of vehicles is one of the main causes of traffic congestion, accidents, energy waste and environmental pollution. Recently, several intelligent applications are equipped in modern vehicles such as advanced driver assistance systems (ADAS), especially an adaptive cruise control (ACC) system which was successfully implemented on some luxury cars and still remains to be an...
This paper concerned with the adaptive tracking control problem of an adaptive model-based fuzzy-neural networks (FNNs) sliding mode control (AFSMC) scheme for a class of nonlinear systems, which are represented by Takagi-Sugeno (T-S) fuzzy model to express a nonlinear systems model. Then, an adaptive parameter estimator is proposed to estimate the unknown nonlinear system parameters. Considering...
A large number of real-world problems nowadays require that decisions be made in the presence of uncertainties. Traditionally, the task of separation systems design neglects the influence of uncertainties. This work, however, explores the optimization strategy of a frequently encountered equilibrium-based distillation system design problem in the face of uncertainties. In particular, uncertainties...

A 2.4/5.8-GHz dual-band programmable-gain upconverter with a constant IF bandwidth is demonstrated using 0.35-µm SiGe BiCMOS technology. Using a current-mode design approach, the input IF bandwidth remains the same at different gain settings. A dual-band LC current combiner is used at the mixer RF output to combine differential signals to a single-ended one at two bands. Then, a wideband amplifier...
Load testing and cross-browser testing are ones of the web testing types particularly reliant on the support of cloud computing platforms for the implementation of TaaS. The main challenge involved in the composition of heterogeneous web application testing tools is the incompatibility of their inputs and outputs. However, the need to manually configure the tools greatly undermines the convenience...
Due to the economic recession in recent years, although the total unemployed population is not retreated, the employee turnover rate in semiconductor packaging factory is frequent, and demission rate and manpower gap are high. Enterprises are always in the vicious cycle of employee demission, recruitment and education training. Under the fierce competition of globalization, semiconductor packaging...
