In this paper, the area effect of floating polysilicons above the drain-side STI on ESD robustness of high voltage components is studied by 0.25-μm 60-V p-channel LDMOS devices. In general, near the gate and drain-side STI regions have high lateral electric-field peaks. Therefore, some floating polysilicon islands above this STI region can be used to reduce the electric-field peak (to increase the breakdown voltage), and then to evaluate its ability of ESD improvement. There are five kinds of width modulation by the vertical arrangement. From the experimental data, the breakdown voltage of pLDMOSs will increase slightly after embedding these vertical floating polysilicon, the trigger voltage will gradually increase by 0∼2V with increasing the floating polysilicon width. Meanwhile, comparing with the reference device ($I_t2$= 0.758 A), the highest secondary breakdown-current ($I_t2$) can be upgraded to 1.042 A and increased about 38%.
本文采用0.25-μm - 60 v p沟道LDMOS器件，研究了漏极侧STI上方浮动多晶硅对高压元件ESD稳健性的面积效应。一般而言，栅极附近和漏极侧STI区域具有较高的横向电场峰值。因此，可以在该STI区域上方放置一些浮动多晶硅岛来降低电场峰值(提高击穿电压)，进而评价其ESD改善能力。宽度调制有五种垂直排列方式。从实验数据来看，嵌入这些垂直浮动多晶硅后，pLDMOSs的击穿电压会略有升高，触发电压会随着浮动多晶硅宽度的增加而逐渐升高0 ~ 2V。同时，与参考器件($I_t2$= 0.758 A)相比，最高二次击穿电流($I_t2$)可提升至1.042 A，提高约38%。

The effects of PVA emulsion / PP fiber on the properties of porous concrete is investigated. The experimental results show that the PVA emulsion can significantly improve the compression strength of porous concrete whereas the effect of PP fiber is not obvious. When the content of emulsion or fiber is 1 wt. %, the abrasion loss of porous concrete decreased by 44.1 % or 54.1 %, respectively. Simultaneously, the corresponding chromatic aberration is 44.8 % or 53.3 % lower than unadulterated sample, respectively.

Shrimp is one of the most important aquaculture products in Taiwan but has suffered a decreasing breeding rate these recent years. It’s difficult to observe their feeding, growth and health due to the muddy and turbid water conditions in shrimp farms. This paper presents the prototype of an underwater surveillance system, which consists of hardware and software to provide underwater observation and automatic analysis for the purpose of smart feeding control and water quality management, and thus improve the farm’s productivity.

This paper presents the development of a frequency comb using a mode-locked fiber laser as the light source for precision dimensional metrology. The mode-locked laser generates an optical pulse train with a central wavelength of approximately 1560 nm. The pulse train was amplified with an erbium-doped fiber amplifier, and its spectrum was broadened to the wavelength range from 1000 nm to 2000 nm. Furthermore, the carrier envelope offset beats were successfully detected by using a common-path f-2 f interferometer.

Crowd counting and density estimation is a challenging task in the field of computer vision. Most of existing methods of this task are based on convolutional neural network (CNN), which have achieved good results in low-density scene. Usually, people who are far away from the camera appear to be denser and smaller, while those who are close to the camera are more sparse and larger, therefor, structure contains only CNN gives the poor performance in some high-density crowd scene because of the uneven distribution of the crowd through camera. To address this problem, this paper designs a CNN-RNN Crowd Counting Neural Network (CRCCNN), which introduces Long Short-Term Memory (LSTM) structure, we use CNN structure to extract the features of the whole image, and use the LSTM structure to extract the contextual information of crowd region. Since LSTM has a good memory of the input information of sequential samples, it can predict the crowd density very well even for the high density population. We perform our experiments on different datasets and compare with other existing methods, which achieve the outstanding results and demonstrate the effectiveness performance of CRCCNN.
