Abstract
According to statistics, the accident rate caused by fatigue driving and mental inconcentration in traffic accidents accounts for 93%. To solve this problem, 68 key points of face are introduced in this paper. Based on deep learning and machine vision algorithm concepts, combined with YOLOv8 model and related fatigue driving judgment mechanism, PERCLOS algorithm, MAR algorithm, EAR algorithm and HPE algorithm are used to improve the accuracy and reliability of the system. A set of algorithms for recognizing tired driving behavior is successfully constructed.

Whale Optimization Algorithm with Aquila Exploration Method
QI Xin YU Yan MA Ning WU Hao-qian
Computer & Telecommunication. 2023,
1
(11): 7-13. DOI: 10.15966/j.cnki.dnydx.2023.11.007
Abstract
The Whale Optimization Algorithm (WOA) is an effective meta-heuristic. However, whale optimization algorithms tend to converge slowly and are prone to fall into local optimal solutions. Therefore, this paper proposes an algorithm based on the exploration idea of the Aquila Optimizer (AO) to solve global optimization problems. The improved algorithm is inspired by the exploration idea of the Aquila Optimizer. Firstly, Aquilas conduct exploration to expand the search range, thereby enhancing the global search capability and reducing the likelihood of getting trapped in local optima. Secondly, it incorporates the hunting behavior of whales to balance the exploration and exploitation phases of the algorithm. To validate the effectiveness of the algorithm, this study uses benchmark test functions as experimental objects and compares it with other popular metaheuristic algorithms. The experimental results demonstrate that the proposed algorithm in this study has shown good convergence speed, optimization accuracy, and stability.

Simulation Analysis of Race-hazard in Combinatorial Logic Circuit Based on Proteus
LI Zhen-dong HOU Zeng-tian HUANG Yong-mei
Computer & Telecommunication. 2023,

(11): 14-. DOI: 10.15966/j.cnki.dnydx.2023.11.002
Abstract
In order to teach students more intuitively the phenomenon of race-hazard in combinational logic circuits, this study builds a simulation module circuit based on Proteus simulation software, and carries out simulation experiments to test the generation and elimination of circuit race-hazard. The simulation interface clearly displays the peak pulse of race-hazard, as well as the elimination results. Through this simulation module circuit, students not only observe the process of race-hazard more intuitively, but also can take different measures to eliminate circuit race-hazard. Teaching practice shows that the simulation module circuit provides a new scene for students to learn and understand the race-hazard phenomenon, thus improving the teaching effect.

Abstract
The new technology and new concept in the era of digital intelligence have profoundly changed the way of operation, organization, production and decision-making in all walks of life. Under the impact of Big Data and Artificial Intelligence, the employment position has higher requirements for the computer skills and literacy of applied talents. The course of Computer Public Basic aims at cultivating students' computational thinking, computer technology and literacy, which plays an important role in improving the vocational skills of applied talents. Take Daqing Normal University, an application-oriented undergraduate university with characteristics in Heilongjiang Province, for example, this paper introduces the reform and practice of the education model of Computer Public Basic. On the basis of analyzing the computer ability required for application-oriented talents in the new era, this paper introduces the reform and practice path from four aspects: hierarchical curriculum system, mixed teaching mode, experimental teaching reform and innovation and entrepreneurship ability training.

Prediction of Waterlogging Depth in Bridges and Culverts Based on PSO-SVR
XUE Zi-yun LI Zhong WANG Zhi ZHANG Li-li SONG Qing-chang
Computer & Telecommunication. 2023,

(11): 29-.
Abstract
Urban waterlogging is an important urban disaster, and culvert ponding is one of the main manifestations of urban waterlogging, which can easily cause serious casualties and property losses. In order to improve the efficiency and accuracy of predicting the culvert ponding depth, a predicting model naming PSO-SVR is proposed, which the current meteorological data and waterlogging depth data are selected as input and output vectors respectively. Firstly, a support vector regression prediction model (SVR) for the culvert ponding depth is established, and then the particle swarm optimization algorithm (PSO) is used to optimize key parameters, which has the advantages of objectivity and simplicity. The experimental results indicate that the PSO-SVR model is effective in predicting the depth of culvert ponding. Compared with traditional prediction models of SVR and BP neural network, the PSOSVR model has higher fitting accuracy for waterlogging depth. This model can provide technical support for urban waterlogging warning and emergency rescue decision-making.

Robot Path Planning Based on Improved DQN Algorithm
MA Hao-dong CHEN Ling-ling JIN Xiao-hang
Computer & Telecommunication. 2023,
1
(11): 37-41. DOI: 1008 - 6609 (2023) 11 - 0037 - 05
Abstract
To address the issues of slow convergence and low success rate in robot path planning associated with the DQN algorithm, this study introduces an enhanced version of the DQN algorithm named MDQN. This enhancement involves modifying the configuration of the state space to more accurately distinguish different states, resulting in a more realistic observation space. Additionally, by altering the reward function, the algorithm is capable of obtaining more reward values, thereby improving learning efficiency. Experimental evaluations conducted on grid maps demonstrate that the improved algorithm, when compared to the traditional DQN algorithm and other related approaches, offers advantages such as higher success rates, faster convergence, and shorter paths.
