Strong orthogonal arrays(SOAs) were recently introduced and studied as a class of spacefilling designs for computer experiments. To surely realize better space-filling properties, SOAs of strength three or higher are desirable. In addition, orthogonality is also an important property for designs of computer experiments, because it guarantees that the estimates of the main effects are uncorrelated. This paper first provides a systematic study on the construction of(nearly) orthogonal strength-three SOAs with better space-filling properties. The newly proposed strength-three SOAs enjoy almost the same space-filling properties of strength-four SOAs, and can accommodate much more columns than the latter. Moreover, they are(nearly) orthogonal and flexible in run sizes. The construction methods are straightforward to implement, and their theoretical supports are well established. In addition to the theoretical results, many designs are tabulated for practical needs.

This study delves into the feasibility of using amorphous silicon photocells as photosensitive units for retinal prostheses. Firstly, theoretical simulations coupled with experimental results demonstrated its strong light absorption and quantum efficiency within the 300—800 nm range. Subsequently, measurements on its visual sensitivity properties were conducted. The findings revealed that under photopic vision conditions, the photocells could provide the stimulating current required for the human retinal nerve cells. Finally, the visual spectral sensitivity curve of the amorphous silicon photocells was assessed, and the results indicated that the spectral sensitivity curve of the amorphous silicon photocells closely mirrors the visual function curve of the human eye under photopic conditions, demonstrating a response to light across various wavelengths.

驾驶意图识别能有效提高自车对其他交通参与者的轨迹预测能力,是实现智能车自主决策和规划的基础。然而动态复杂交通环境下周围车辆的交互是实现准确可靠驾驶意图识别亟待解决的挑战之一。为提高在动态复杂交通场景下驾驶意图识别的准确率,提出基于双向图长短时记忆网络(Bidirectional graph long short term memory,Bi-GLSTM)网络的驾驶意图时序识别模型。首先基于局部加权回归散点平滑法对原始数据集中的位置、速度和加速度进行平滑处理,并联合纵横向运动参数为数据标注驾驶意图;然后建立图注意力神经网络,分析和提取周围车辆与目标车辆之间的交互特征,嵌入注意力机制,分析周围车辆对目标驾驶意图的重要性,增强模型对相关性较大的车辆运动状态关注程度;融合周围车辆交互特征和目标车辆历史运动特征,为提高模型在动态复杂交通环境下的鲁棒性和可靠性,基于双向长短时记忆网络提取特征之间的时序特征;最后在公开数据集HighD上训练并验证模型的有效性,结果表明相比于图神经网络、循环神经网络等模型,识别准确率分别提高了11.33%、55.31%;通过可视化注意力权重,说明所提出的模型也一定程度上解决了可解释性问题。

针对光线在水中的散射和吸收效应造成水下图像纹理和结构不清晰的问题,提出一种基于卷积调制(CM)与空间协作(SC)的水下图像增强算法。以编码器-解码器作为基础网络,使用RepVGG的浅层和深层网络分别提取水下图像的纹理和结构特征。首先,特征主导网络将RepVGG中提取到的水下图像特征转化成具有不同尺度的纹理和结构特征,使其与解码器中的特征图进行拼接融合。其次,在编码器中使用卷积调制模块,采用深度可分离卷积(DSConv)模拟自注意力机制的方式减少图像细节信息的丢失,提高编码器特征提取的能力。最后,在解码器中使用空间协作卷积(SCConv),在空间维度上处理水下特征保留更多的位置信息,以提高解码器对融合后特征的增强能力。实验结果表明,该算法在视觉感知与性能指标上优于对比算法,峰值信噪比(PSNR)和结构相似性(SSIM)指标最高达到23.4465 dB和0.8946,水下彩色图像质量评价(UCIQE)和水下图像质量测量(UIQM)指标最高达到0.5826和3.0689,进一步证明了该算法能够有效增强水下图像的纹理和结构特征,具有较好的视觉感知效果。
