Published: May 2024

Rekomendasi jalur yang optimum sangatlah dibutuhkan oleh para pemudik. Hal ini disebabkan oleh banyaknya permasalahan yang dihadapi pada saat melakukan perjalanan mudik. Ada asumsi bahwa pengambilan rute yang tepat dapat mengurangi waktu dan biaya yang dibutuhkan selama perjalanan mudik. Oleh karena itu, dibutuhkan suatu perhitungan yang dapat merekomendasikan rute yang efisien pada jalur mudik. Salah satu metode yang dapat menyelesaikan permasalahan jalur terpendek adalah algoritma lebah. algoritma lebah itu sendiri terinspirasi dari perilaku sosial koloni lebah dimana seekor lebah dapat menjangkau sumber makanan dengan rute terdekat. Setelah mereka menemukan makanan lebah–lebah akan kembali kesarang dan menginformasikan sumber makan yang dia temukan kepada teman–temannya dengan menggunakan waggle dance. Dalam penelitian ini pencarian jalur terpendek yang dilakukan lebah tidak hanya mempertimbangkan jarak saja, tetapi mempertimbangkan heuristik lainnya seperti kemacetan, lampu jalan, jalan tol, rawan bencana dan keamanan. Sehingga rute yang dihasilkan merupakan rute yang optimum. Hasil yang didapat dari mengimplementasikan algoritma lebah untuk pencarian jalur terpendek dengan mempertimbangkan heuristik adalah rute jalur optimum yang bisa dilalui dari kota awal ke kota tujuan beserta panjang jalur yang dapat ditempuh.

Authors: Zhao Lei , Zhang Guobin , Li Zehua , Liu Zhenzhong
Published: May 2024

Existing neurosurgical robots are prone to interfering with each other in a narrow operating space due to the overlapping of several arms, which poses a great safety risk during surgery. In this paper, a 7-DOF dual-arm robot is designed to cooperate with the surgeon to complete craniotomy by manipulating the master hand mechanism. Aiming at the pain point that two real-time dynamic slave hands are prone to interference, this paper establishes a simplified model of the robot envelope, and transforms the interference detection problem between the robots into the interference checking of geometric primitives. If the interference between the two arms is detected by the algorithm, the surgical path of the current robotic arm is immediately terminated to ensure the safety of the surgery. Finally, the algorithm is simulated and verified with the robot designed in this paper. The results show that the algorithm is feasible and has high computational efficiency.

Authors: Yu Xiaoqing , Wu Hongen , Wang Yongquan , Qin Jiangbing
Published: May 2024

In the realm of machine learning-based target detection, there exist several challenges that require attention, namely limited detection range, complex feature extraction, suboptimal detection precision, and significant subjectivity. In this paper, the strengths and weaknesses of existing deep learning target detection algorithms have been investigated in order to address these issues by integrating the actual welding process of heat exchangers. The objective is to improve the model’s detection accuracy and speed. To achieve this, we employ the YOLOv5 model to detect and identify weld defects of the heat exchanger tube plate, and propose an enhancement method based on the YOLOv5s model. By implementing several enhancements, such as incorporating the attention mechanism, updating the loss function, and optimizing the feature fusion network, the model’s overall performance is enhanced, with a focus on addressing the issues of low detection accuracy, slow convergence, and inadequate real-time performance in detecting small target defects compared to the YOLOv5s model. The improved YOLOv5s_m model improves the detection accuracy by 4.52% and the speed by 4.4 FPS, which solves the problems of low detection accuracy, weak sensitivity of small target defect detection and poor convergence of the bounding box loss function of the YOLOv5s model. These improvements lay the groundwork for enhancing the automation and intelligence of weld quality inspections.

Published: May 2024

During long-distance pipeline transportation of dense pastes, the periodic reciprocating pumping shock of the pump leads to serious vibration in the pipeline system which reduces the reliability and life cycle of the system. The vibration of the pipeline system varies based on the materials used and the filling volumes. To analyze the effect of filling volumes and material’s mass concentration on inherent frequency of pipes, vibration modal experiments were carried out on water filled pipes and coal slurry filled pipes through LMS multi-channel vibration noise test and dynamic analysis system. The results show that for water filled pipe, the inherent frequencies of the first three modes of pipe decreased with the increase of water filling volumes. For coal slurry paste filled pipe, in the same mass concentration range, the inherent frequencies of the first three modes of pipe showed a downward trend with the increase of filling volumes. When the filling volumes is the same, the inherent frequencies of the first three modes of the pipe generally increased with the decrease of the coal slurry’s mass concentration.

Published: May 2024

The noise generated by fan blades is the main noise source of axial flow fans used in mines. Because of its excessive noise, the need for noise reduction is increasingly urgent. This paper takes a certain type of mine axial fan as the research object, uses Lighthill acoustic analogy theory, FW-H acoustic wave equation and Fluent numerical simulation method to compare the performance of the fan under uniform and non-uniform distribution of the guide vane, and focuses on the influence of the guide vane layout on the aerodynamic performance, flow field characteristics and noise characteristics of the fan. The results show that, compared with the uniform distribution of the guide vane, the non-uniform distribution can reduce the sound pressure level of discrete noise in the fundamental and harmonic frequencies to different degrees, and the sound energy of the fundamental and partial harmonic frequencies can be distributed in a wider frequency band, but the total sound pressure level of the fan is basically unchanged. Selecting A reasonable distribution mode can ensure the aerodynamic performance and flow field characteristics of the fan, and play a significant noise reduction effect on the low and medium frequency noise, in which the modulation amplitude A=0.2 has the best effect, and the modulation amplitude is reduced by 13.6dB at 550Hz.

Application of Insect Growth Regulators (IGRs) as Biopesticides for Sustainable Agriculture
Authors: Dr. Kavita Krishnamoorti
Published: May 2024

The application of conventional pesticides is underlined by many negative externalities including environmental degradation and pest resistance. Consequently, use of biopesticides as alternative agrochemicals is recommended to meet sustainable development goals. Insect growth regulators (IGRs) are biochemical biopesticides. Actually, Biochemical biopesticides are compounds (or exact synthetic analogue) of natural origin possessing active ingredients that control pest in a way that are nontoxic to the target pest, the environment and humans. So, insecticides with growth regulating properties may adversely affect insects by regulating or inhibiting specific biochemical pathways or processes essential for insect growth and development. Ecdysoids and Juvenoids (JH mimics) are among the most promising IGRs. Ecdysoids are synthetic analogues of natural ecdysone and when applied in insects, kill them by formation of defective cuticle. Juvenoids (JH mimics) are synthetic analogues of Juvenile Hormone (JH). Juvenoids have anti-metamorphic effect on immature stages of insect. Along with this, Anti JH or precocenes which act by destroying corpora allata and preventing JH synthesis also act as IGR. In this way, Insect Growth Regulators are potential substitute of insecticides that could be commercially used.

Abstrak - Di era digital, pendidikan tinggi dihadapkan pada tantangan untuk merespons secara efektif terhadap umpan balik mahasiswa, yang merupakan kunci untuk meningkatkan kualitas layanan kampus. Penelitian ini dirancang untuk mengoptimalkan proses klasifikasi umpan balik tersebut dengan menggunakan sinergi antara algoritma Random Forest dan teknik Synthetic Minority Over-sampling Technique (SMOTE) dalam analisis sentimen. Data dikumpulkan dari berbagai saran mahasiswa, diikuti dengan tahapan pra-pemrosesan yang meliputi pembersihan, tokenisasi, dan penghapusan stopwords. Setelah pelabelan sentimen menggunakan lexicon yang terverifikasi, SMOTE diterapkan untuk mengatasi ketidakseimbangan kelas dalam dataset. Hasil menunjukkan bahwa sebelum penerapan SMOTE, terdapat bias terhadap kelas mayoritas, namun setelah aplikasi SMOTE, terjadi peningkatan yang signifikan dalam presisi dan recall terutama pada kelas minoritas, meningkatkan akurasi klasifikasi secara keseluruhan. Hasil ini menggarisbawahi pentingnya penerapan teknik penyeimbangan data dalam analisis sentimen, menunjukkan bahwa pendekatan ini dapat memberikan wawasan yang lebih seimbang dan mendalam, serta mendukung institusi dalam membuat keputusan yang tepat dan responsif terhadap kebutuhan mahasiswa..Kata kunci: Analisis Sentimen, Klasifikasi Teks, Random Forest, SMOTE. Abstract - In the digital age, higher education faces the challenge of effectively responding to student feedback, which is key to enhancing campus service quality. This study is designed to optimize the feedback classification process by leveraging the synergy between the Random Forest algorithm and the Synthetic Minority Over-sampling Technique (SMOTE) in sentiment analysis. Data was collected from various student suggestions, followed by preprocessing stages that included cleaning, tokenization, and the removal of stopwords. After sentiment labeling using a verified lexicon, SMOTE was applied to address class imbalances in the dataset. The results indicate that before the application of SMOTE, there was a bias toward the majority class, but after the application of SMOTE, there was a significant improvement in precision and recall, especially for the minority classes, enhancing the overall classification accuracy. These findings underscore the importance of applying data balancing techniques in sentiment analysis, demonstrating that this approach can provide more balanced and in-depth insights, as well as support institutions in making accurate and responsive decisions to student needs.Keywords: Sentiment Analysis, Text Classification, Random Forest, SMOTE.
