The Key English Pronunciation Difficulties for Egyptian EFL Learners by Hasnaa Hasan Sultan Abdelreheem

“…The project involves both contrastive analysis (of the phonological systems of English, Egyptian Arabic and Modern Standard Arabic) as well as error analysis. While the significance of contrastive analysis lies in helping EFL teachers predict the problematic aspects (Al-Saqqaf and Vaddapalli 2012, 56), error analysis would provide them with the actual problems encountered by the learners and the extent of their seriousness.…”

Novel level shifter based physical unclonable function circuit design by Lijuan HAN, Lei QIAN, Enyi YAO, Xin LOU, Yuan CAO, Yanhua LIU

“…Level shifters are widely used in low-power, multi-threshold integrated circuit chips.A novel physical unclonable function (PUF) design based on cross-coupled level shifter was proposed.In this work, a single switching transistor was inserted in the level shifter, which was the only overhead per response bit to change the operation mode of the cross-coupled level shifter from differential to common.The signature of the PUF was extracted while in common mode, by exploiting the uncertainty of the output voltage due to the difference of the switching time of the two PMOS in the cross-coupled network.Simulated with a standard 65 nm CMOS process, the results show the proposed PUF can produce a uniqueness of 49.11% and a reliability of 96.09% with the power supply voltage ranged from 1.0 V to 1.5 V and 95.31% with the temperature ranged from -20 ℃ to 100 ℃.The energy per bit is only 0.72 pJ at a high throughput of 20 Mbit/s (1.2 V, 27 ℃).…”

Objective assessment of communication speech interference effect based on feature fusion by Yun LIN, Huaitao XU, Sen WANG, Sicheng ZHANG, Long ZHUANG

“…In view of the objective assessment problem of the effect of communication speech interference, methods based on multi-measurements and multimodal fusion were proposed.First, the interfered speech was preprocessed by the endpoint detection algorithm and time warping algorithm.Then, the content of speech was extracted and performed measurement calculated with the standard speech to obtain five kinds of measure.After the fusion of five measures, random forest model was used to assessed the quality level.Finally, a neural network model based on residual structure was designed combined multimodal fusion technique, which fused the graph domain and measure domain features of the interfered speech data and performed quality level assessment.Experimental results show that the accuracy of two methods have reached more than 90%.Among them, the multimodal assessment method improves the accuracy by about 3.269% compared with the existing research methods, which proves that it has a better performance.…”
