This study researches and develops the new electric vehicle rearview mirror system of the intelligent network system. It has dual spindles to select the direction of rotation. Its functions include: (1) In addition to developing electric rearview mirrors for electric vehicles, it is equipped with memory motors, which can memorize at least 3 sets of positions. To provide the electric rearview mirror memory angle for electric vehicle driving, you can choose outside the rearview mirror angle and can memorize up to 3 sets of angles, which guarantees the initial safe driving angle of electric vehicle driving. (2) The second rotation axis design, linked driving steering wheel device can provide the rearview mirror to adjust the angle of view direction synchronously when the electric vehicle is driving and turning, so as to ensure that the steering has no dead angle design. After various tests, the error values of the designed control parameters are all below 3%, reaching and safe setting.

In this study, a cerium oxide (CeO2) thin film on Metal-Oxide-Semiconductor (MOS) structure was prepared by sol-gel method. Cerium nitrate (Ce(NO3)3·6H2O) powder and isopropanol solution was used as the coating solution and various chelating agent (glacial acetic acid) volumes of 0, 2, 3, 4, and 5 ml were mixed in hit to prepare CeO2 films, and annealed with oxygen for 1 hour. The electrical characteristics were measured to examine the film qualities, including oxide capacitance (Cox), leakage current density, k value, equivalent oxide thickness (EOT), effective oxide charge density (QEFF), and interface density (Dit). The corresponding values are 79.1 pF, 6.4×10-4 A/cm2 at +5V, 24, 30.9 nm, 2.03×1011 cm-2, and 1.93 × 1011 cm-2eV-1, respectively. Based on these data, it can be considered that CeO2 thin films by sol-gel method on Si exhibit a good quality and can be used as an advanced gate oxide on MOS structure in the near future.

In this paper, we apply deep learning-based (DL) approach to solve the hybrid precoding and combining design problem in millimeter wave (mmWave) multiple-input multiple-output (MIMO) systems. After training process, we feed testing data set into neural network (NN) and obtain phases of RF analog precoders and combiners. Given a RF analog precoder, we can acquire baseband precoders by using least square solution and the similar way is applied to RF analog combiner to acquire baseband combiner. As indicated in the simulation results for the evaluated spectral efficiency based on the outputs of DNN, it shows that the performance of our method is competitive.

We introduce deep reinforcement learning (DRL) into a Taiwanese mahjong program, and compare the pros and cons of traditional tree search methods and DRL in terms of effectiveness and efficiency. Our DRL-based program aims to learn good strategies comparable to the state-of-the-art Taiwanese mahjong program Verylongcat, and has demonstrated effective learning capability in the experiments. Moreover, the required computation time of our DRL-based program is significantly lower than the Verylongcat version, bringing great advantage in time-limited tournaments.

This paper uses TCAD to simulate the modulation of a 0.18-μm 60 V nLDMOS device with a floating P+ embedded in the drain side by dividing the drain side into one-half and embedding the floating P+ near the drain outer side, which will increase the P+-zone length in different modes.The simulation is carried out with an input current of 1E-5 amps, and the trigger voltage, breakdown voltage, and electric field of the devices can be obtained from the TCAD simulation. By embedding the floating P+, it was found that the electric field could be reduced and the breakdown voltage of the device could be increased. In the design, the floating P+ with a length of 9 μm is embedded in the drain outer side, and the breakdown voltage is increased from 96.42 V to 119.29 V, so that the ESD immunity of the device can be improved.

In this research, a hybrid convolutional neuron network (CNN) model was developed for cataract detection. The full fundus image in the original dataset will be divided into four segments that created five fundus image datasets and trained by five different CNN models which have the same structure. The five model predictions will pass through majority voting to get the final prediction. The experimental result shows that the proposed hybrid CNN performs better than stand-alone models.

Herein, we designed and simulated the monolithic integration of photo-diode (PD) and transimpedance amplifier (TIA) in CMOS 90 nm technology. In the standard process, a PN-junction structure with an illuminated area of 39.48 $mu$m × 39.48 $mu$m was designed as the PD. The breakdown voltage of the PD is -10.5V. At a reverse bias voltage of 3V, the PD has a dark current of 2.6 pA and a capacitance of 1.03 pF. The TIA is composed of a regulated gate cascode circuit, a differential amplifier paralleling with an edge peak generator. The PD and the TIA are monolithically integrated, the overall transimpedance gain is 40.3 dB$Omega$, and the bandwidth is 4.1 GHz. The integrated design of PD and TIA could be applied in 5 Gb/s optical receivers.

The factors of indoor air quality are affected by the density of people, the size and time of opening the door, and the arrangement of the air inlet and outlet of the ventilation equipment. We found that the optimal CO2 of the cross opening was reduced by 109.7 ppm/min through CO2 concentration detection. However, natural ventilation can result in higher indoor temperatures. Therefore, this study increases mechanical ventilation equipment and explores natural and mechanical ventilation to achieve ventilation energy saving.
