State-of-the-art closed-loop switched-capacitor (SC) designs usually regulate the output voltage by pulse frequency modulation (PFM) with the disadvantage of large electromagnetic interference (EMI). It may cause the failure of the Internet of Everything (IoE) devices. This paper proposes the hybrid digital low drop-out (DLDO) SC converter with a constant switching pulse width modulation (PWM) control...
Recently, convolutional neural networks (CNNs) have achieved great success in fields such as computer vision, natural language processing, and artificial intelligence. Many of these applications utilize parallel processing in GPUs to achieve higher performance. However, it remains a daunting task to optimize for GPUs, and most researchers have to rely on vendor-provided libraries for such purposes...
Different from conventional multiphase switched-capacitor (SC) DC-DC converters, the proposed unsymmetrical parallel switched-capacitor (UP-SC) regulator provides more controllable input variables to increase available conversion ratios for improved load regulation. Even under higher conversion ratio numbers, the UP-SC regulator uses the fast searching optimum ratio (FSOR) technique to search the...
The stacking MOSFET structure composed of low-voltage devices suffers from deteriorated transient response or large footprint area when capacitor-free or dominant pole compensation low dropout (LDO) regulator biases the driver. Due to self-stabilized feature, the proposed stacking MOSFET driving (SMD) technique effectively drives the power stage and greatly reduces noise interference from the noisy...
A 3D microfluidic chip for resistance of H460 lung cancer cells (LCC) was demonstrated. H460 LCC could be restrained by the injection of different curcumin concentration and investigated in different microenvironmental pH conditions. In the range of curcumin concentration of 57.2–100 μg/mL, the average apoptosis rate (AR) of H460 LCC were 53.6%, 58.4%, and 98.0% for pH=6.5, 7.4, and 8.5 microenvironments,...
A centrifugal microfluidic device (CMD) is demonstrated for organophosphorus pesticides (OPP) sensing. CMD is designed as a CD-like to have a sequential sample injection with capillary valves controlled by centrifugal force, i.e. rotational speed (rpm). OPP in CMD could be successfully derived into a mixer at 570 rpm and then spined into a detection reservoir at 2000 rpm. The experiment results indicated...
As a most important part of students majoring in computer science related areas, experiments contribute to not only better understanding the theoretical knowledge but also enhancing the ability of hands-on. However, traditional laboratories require a high-cost investment on both site and equipment, especially experiments of computer network. In order to address these problems, we design a virtual...
The rapid development of intelligent terminals and mobile Internet industry has brought many challenges and opportunities to the mobile network. Mobile Network Open Services can provide users and developers with the open resources consisted of network infrastructure, network data and diversified services, so as to build an open, flexible, collaborative Internet ecosystem. The ability to open the mobile...
A volatile organic solutions (VOS) sensor with plasmonic metasurface is proposed and demonstrated in the near-UV wavelength range. The plasmonic metasurface device (PMD) is composed of the hybrid of metal/dielectric/semiconductor nanostructures. These nanostructures are fabricated by using natural lithography technique for wafer-level fabrication, which hybridized resonances could enhance electromagnetic...
Taiwan is a mountainous and geologically active country with but land resource for residential development is limited. Under a crowded population pressure, the use of land resources is often overrun. Many hillside had been improperly developed. It causes significant impact on natural environment and the people's lives and property. This paper proposed to use the archival images of the Formosat-II...
Elementary schools are considered as the important stage for the enlightenment of multiplication. The establishment of the language of multiple and multiplication concepts is the key point of students mathematical learning in this stage. Combining scaffolding with rapidly developing technologies to assist students in achieving higher-level development is the primary task for teachers. Aiming at students...
This paper proposed an effective vehicle detection system based on wheel parts detection. The system is composed of two principal modules: feature detector construction and vehicle detection. Feature detector construction is to train a vehicle part model based on Adaboost using HOG and MB-LBP. Vehicle detection is formed by three sub-modules. ROI segmentation segments the searching region where wheels...
A full-bridge single-stage high power-factor charging circuit has accomplished a lithium battery charger. With no extra design effort required, the presented charger possesses Reflex charging function. Unlike the inherited resistive power dissipation of Reflex charging method, the developed circuit transfers the energy from the battery to an inductive component and return to battery later to fulfill...
Real-time recovering an accurate 6 DoF pose of a known planar target is essential for augmented reality and robotics applications. Despite several pose estimation tracking systems have been proposed over recent years, there is still the need for a more efficient and more accurate solution for general planar objects. In this work, we develop an innovative GPU implementation of a real-time pose estimation...
Through MOOCs and social media platforms, users can share, track, and search for the information of their specific interests. Thus, they can make interactive discussions as well as social media learning on multimedia texts and learning materials. This paper proposes a big data analysis technique on learning portfolio to explore how the interaction, unknown correlations, and hidden patterns among learners...
A well-organized meeting point should enhance the efficiency between travelers and people who are there to meet them. When picking up or seeing off passengers at an airport, the driver usually selects a meeting place according to the locations of airport entrances and exits, and mode of transportation. Whether the signs can be recognized easily, the colors of the signs, and how quickly they can get...
Digital Light Process (DLP) is a common technology used in 3D printing. However, problems such as non-proper adhesive usually happen without vibration of the resin tank during the separation scenario in DLP. Therefore, this study aims to develop a real-time system to earlier detect these problems by monitoring vibration of the resin tank. If no vibration is detected, a false alarm via internet to...
This study examines the optimal offshore wind farm layout for a fixed number of wind turbines and a fixed covered area.
