Due to the improvement in the car manifacture, the rate of road traffic accidents is increasing. To solve these problems, there is loads of attention in research on the development of driver assistance systems, where the main innovation is traffic sign recognition (TSR). In this article, a special convolutional neural network model with high accuracy compared to traditional models is used for TSR. the Uzbek Traffic Sign Dataset (UTSD) applied in the zone of Uzbekistan was created, consisting of 21.923 images belonging to 56 classes. We proposed a parallelcomputing method for real-time processing of video haze removal. Our utilization can process the 1920 x 1080 video series with 176 frames per second for the dark channel prior (DCP) algorithm. 8.94 times reduction of calculation time compared to the Central Processing Unit (CPU) was achieved by performing the TSR process on the Graphics Processing Unit (GPU). the algorithms used to detect traffic signs are improved YOLOv5. the results showed a 3.9% increase in accuracy.

Capturing more details and features of traffic data by combining information at different scales is one of the practical approaches to address cybersecurity challenges in industrial environments. TCNs can improve the model's ability to extract multi-scale information by adjusting the size of the convolutional kernel or the number of convolutional layers. However, the approach still falls short in capturing anomalous patterns hidden in global dependencies, which leads to the model's accuracy on certain long-duration attack categories with reduced accuracy. this paper proposes a novel industrial intrusion detection based on Multiscale TCN and Transformer fusion (MTTN). A parallel mechanism is included in *** the first branch, the TCN is improved in terms of scale and structure to establish the connection between forward and backward traffic sequences and enhance the extraction of multi-scale temporal features of the model. In the second branch, patches with different sizes and dimensions are fed into the Transformer to capture the global multi-scale information of the network traffic. the features from these two branches are fused to improve the model detection performance. A series of experiments on the proposed method on two public datasets (CICIDS2017 and NSL-KDD) demonstrate the effectiveness of the proposed method.

the rotating machineries of automobile, such as gears and motors, are involved with complicated interactions between fluids and structures, resulting in flow phenomenon such as free-surface, moving boundary, thermal conduction etc. Smoothed Particle Hydrodynamics (SPH), due to its Lagrangian nature, is preferred to simulate such phenomenon. the complexities of automobile structures require small particle distancing and therefore large number of particles are needed to discretize both fluid and structure. the small time step of SPH simulation is also required due to intense flowsplashing resulting from high-speedmoving boundary. Both two points above lead to large amount of computation duringSPHsimulation. In this paper, a parallelism framework of weakly compressible SPH(WCSPH) is proposed to accelerate SPH simulation by high-performance computing cluster. A hybrid parallelism strategy, with both Message Passing Interface (MPI) and Intel threading Building Blocks (TBB), is used to reduce the total number of processes and therefore reduce the latency due to communication among computing clusters network. METIS is used to decompose the computational domain enabling dynamic domain decomposition and load balancing. the oil motion inside a gearbox is successfully simulated using the proposed framework, showing that the proposed parallelism framework is applicable to complex industry application and can accelerate SPH simulation efficiently.

In order to identify crop disease accurately and efficiently, we propose a multi-scale parallel fusion convolution network called MSPFNet for the automatic crop disease identification. It combines multi-scale convolution and attention mechanism. By mixing convolution kernels of different sizes in the same convolution unit, multi-scale convolution can identify crop disease features at different scales better. In this paper, Convolutional Block Attention Module is introduced to improve the representation ability of the model. By analyzing the information of spatial attention and channel attention, model can pay more attention to important features. In addition, we design a feature fusion module to realize the fusion of features at different depths. And feature fusion module can solve the problem of the disappearance of disease features in the process of image feature extraction. We validate the proposed model on the publicly available apple leaf pest data set. Experimental results show that the proposed MSPFNet can achieve higher recognition accuracy.

Modern parallel computers could power the perception and compression algorithms small planetary rovers require to navigate long distances, construct detailed terrain maps, and communicate discoveries to Earth. this work identifies and comprehensively characterizes four algorithms important to planetary roving that are well-suited for parallelcomputing. Multiple implementations of dense stereo matching, multi-view stereo, image compression, and triangle mesh compression are evaluated using the NVIDIA Jetson family of high-performance embedded computers. Image and mesh inputs are derived from simulation and used to evaluate the performance, power consumption, and hardware utilization of each device as a function of time. Our results demonstrate the promising capacity for modern embedded computers to expand the range and pace of planetary rover exploration.

We proposed a non-deterministic training approach for memory-efficient stochastic computing neural networks (SCNN). Conventional SCNN simply convert the trained network parameters into stochastic bit-streams at the inference phase. Although stochastic bit-streams can simplify binary multiplication and addition using the principle of probability, memory cost and computation delay are consumed due to extremely long bit-streams. Different from methods that rely on long bit-streams to convert full-precision NN to SCNN during inference, the proposed approach also introduces the concept of non-deterministic computation during training to alleviate the memory requirement growth caused by long bit-streams. To this end, we probabilize NN parameters in the feed-forward process of the training phase, and convert them into 1/4/8-bit stochastic number representations according to the probability, which greatly reduces the memory requirements in SC. In order to alleviate the training instability problem caused by low-bit encoding, we propose a multiple parallel training strategy (MPTS) during the training process to improve the stability of the results. the proposed MPTS achieves a stable training process through a voting mechanism. We evaluate the performance of the proposed training approach on fully connected NN and the MNIST dataset. Compared withthe baseline training method with 97.77% accuracy using 32-bit floating point values, the proposed non-deterministic training approach achieves a reasonable accuracy of 90.34% while using 4-bit stochastic number representations to represent layer weights and biases.
