It can help robots understand human needs more accurately. However, the impact of noise signal and model architecture on accuracy has not been fully explored. In addition, individual datasets are often used for algorithm testing, making it challenging to ensure algorithm generalization. To address these issues, we explore the impact of noise and algorithms on emotion recognition tasks based on two datasets. First, we use SE-ResNet as an emotion recognition network, which guarantees the effectiveness of the algorithm through the attention mechanism and residual structure. Experiments show that SE-ResNet performs better than other classical convolutional neural networks, and it validates the effectiveness of the attention mechanism. Second, we verify that noise can cause the algorithm to lose accuracy by setting up experiments with or without noise. Besides that, we analyze noise’s effect for each emotion class by the confusion matrix. The results show that noise has the most significant impact on the recognition accuracy of natural emotion.","PeriodicalId":32903,"journal":{"name":"JITeCS Journal of Information Technology and Computer Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90422222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the peak rate of the system based on the RE algorithm is studied, and the influencing factors of the peak rate are analyzed. Secondly, the uplink and downlink peak rate of the 4G link is measured by the two transmission modes of antenna and coaxial cable respectively. After comparative analysis, it can be concluded that the transmission mode of coaxial cable is more stable and the SNR (Signal to Noise Ratio) is better. At the same time, it verifies that CPU performance affects uplink and downlink peak rates, and that adjusting the RF (Radio Frequency) gain can achieve the maximum throughput which is also consistent with the theoretical value of peak rates.","PeriodicalId":32903,"journal":{"name":"JITeCS Journal of Information Technology and Computer Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74297292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, taxis queue up for passengers or passengers queue up to take the bus from time to time. Based on this problem, this paper establishes a corresponding mathematical model to analyze the taxi driver's selection strategy after sending passengers to the airport, so that the taxi driver can improve the efficiency of passengers as much as possible, so as to increase the available income. Firstly, in order to further put forward the selection strategy of taxi drivers, this paper reflects the driver's income according to the passenger mileage, no-load mileage, no-load rate and passenger carrying rate of taxis in different periods, and makes a selection strategy for taxi drivers from the aspect of maximum income. Finally, in order to consider the fairness of the airport taxi industry and make the income of these taxis as balanced as possible, we analyze and study from the two aspects of \"short distance vehicles\" and \"long distance vehicles\", and solve the problem of \"boarding points\" by setting up non passable lanes to improve the efficiency of the airport.","PeriodicalId":32903,"journal":{"name":"JITeCS Journal of Information Technology and Computer Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75867707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with other software languages, Java language is widely used in the development of large-scale business systems due to its high access, concurrency, and clustering. Source code is the basic element of building a business application system, and logic vulnerabilities or nonstandard programming in code are the roots of application security events.

In order to obtain this two-parameter at the same time, and to reduce its influence, a test system based on combined FBG is designed. Based on different effect of different core diameter strain, a kind of FBG probe is studied. On the basis of calculating the relationship between wavelength offset and the strain and temperature, the correlation function is deduced, and the coupling mode of the probe and the coupling efficiency are analyzed. In the experiment, strain and temperature test were completed by using light source, transmission fiber, combined FBG and so on. The results show that the wavelength offset is basically the same when the FBG changes with temperature. However, the slope change is quite different when stress changes. Finally, the strain and temperature were tested under different conditions, and the response coefficients of FBG temperature and strain were calibrated. It can be seen that the simultaneous analysis of temperature and strain can be achieved by detecting wavelength offset of combined FBG. The design is no need to weld, taper and other complex technologies. It has simple structure, strong capacity expansion capability and has high application value.","PeriodicalId":32903,"journal":{"name":"JITeCS Journal of Information Technology and Computer Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78386186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At present, most gesture recognition algorithms are based on monocular visual images and recognize the apparent features of hands. Most gesture image segmentation methods are carried out in color space according to skin color information. These methods are highly susceptible to interference from the external environment, such as lighting, background, etc. Convolutional neural network has the advantages of strong anti-interference and outstanding self-organization and self-learning ability. Therefore, based on the principle of convolutional neural network, a novel deep convolutional neural network dedicated to gesture recognition was designed in this paper. This network combines skin color information with finger position information for gesture recognition. Experimental results showed that the algorithm based on fingertip position information has better performance than the algorithm based solely on skin color information. Moreover, the network has simple structure and few parameters. Compared with VGG16 and other classical networks, the recognition accuracy is basically the same under the premise of fewer parameters and structural layers, and the recognition effect is better than other classical networks.","PeriodicalId":32903,"journal":{"name":"JITeCS Journal of Information Technology and Computer Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78624660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
