Abstrak: Tujuan dilakukannya penelitian ini guna menggali informasi terkait pandangan mahasiswa Tadris Matematika terkait kegiatan pembelajaran selama pandemi. Adapun penelitian ini menggunakan pendekatan kuantitatif deskriptif yaitu survei. Sampel penelitian dipilih melalui teknik purposive sampling sebanyak 21 orang dari keseluruhan mahasiswa sejumlah 52 orang. Adapun dipilih mahasiswa semester 3 dikarenakan mahasiswa semester 3 melaksanakan pembelajaran secara daring sedangkan mahasiswa semester 1 melaksanakan pembelajaran secara luring. Alat pengumpulan data penelitian berupa kuesioner. Berdasarkan data didapatkan bahwa mahasiswa memiliki persepsi yang baik terhadap kegiatan pembelajaran daring yang berlangsung selama pandemi. Hal ini ditunjukkan dengan rata-rata nilai IKM (Indeks Kinerja Mutu) 3,03. Namun demikian, hasil persepsi mahasiswa juga menggambarkan aspek yang masih sangat perlu perhatian guna dapat terwujudnya efektivitas suatu pembelajaran daring yakni sarana dan prasarana. Hasil ini akan menjadi refleksi bagi Program Studi Tadris Matematika untuk melakukan evaluasi dan perbaikan kedepannya.
Abstract: The purpose of this research is to explore information related to the views of Tadris Mathematics students regarding learning activities during the pandemic. This research uses a descriptive quantitative approach, namely a survey. The research sample was selected through purposive sampling technique as many as 21 people from a total of 52 students. The 3rd semester students were chosen because the 3rd semester students carried out online learning while the 1st semester students carried out offline learning. The research data collection tool is in the form of a questionnaire. Based on the data, it was found that students had a good perception of online learning activities that took place during the pandemic. This is indicated by the average value of the IKM (Quality Performance Index) of 3.03. However, the results of student perceptions also describe aspects that still need attention in order to realize the effectiveness of an online learning, namely facilities and infrastructure. These results will be a reflection for the Mathematics Tadris Study Program to evaluate and improve in the future.

Abstrak: Hakikatnya Belajar matematika tidak semata hanya menghitung dan menghafal rumus, tetapi tentang bagaimana memahami konsep yang ada. Dalam menyelesaiakan masalah matematika kita dituntut untuk menghubungkan konsep-konsep matematika sehingga penyelesaian bisa diperoleh, hubungan konsep-konsep matematika inilah yang biasa disebut koneksi matematika. Apabila koneksi matematika siswa baik, maka dia dapat menghubungkan ide-ide matematika dari konsep-konsep matematika maupun dari disiplin ilmu lain dan menghubungkan antar konsep-konsep yang sudah diketahui sebelumnya dengan konsep-konsep dari informasi yang baru didapat sehingga pemahaman yang didapat akan lebih sempurna. Tujuan dari penelitian ini adalah untuk mengungkap bagaimana koneksi matematis siswa dalam menyelesaikan masalah ditinjau dari kecenderungan gaya berpikir. Setelah proses pengambilan data dan analisis data, didapatkan hasil: Subjek Gaya berpikir Acak Abstrak cenderung mampu menampakkan semua indikator yang diuji. Subjek-subjek dengan gaya berpikir lain, seperti Sekuensial Konkret, Sekuensial Abstrak, dan Acak Konkret tidak demikian. Fakta menarik lainnya adalah subjek dengan gaya berpikir Sekuensial Abstrak dan Acak Konkret tidak mampu melakukan tahap memeriksa jawaban ketika menyelesaikan masalah matematika.
Abstract: In essence, learning mathematics is not only about calculating and memorizing formulas, but about how to understand existing concepts. In solving mathematical problems we are required to connect mathematical concepts so that solutions can be obtained, the relationship of mathematical concepts is what we call a mathematical connection. If students have good mathematical connections, they can connect mathematical ideas from mathematical concepts as well as from other disciplines and connect previously known concepts with concepts from newly acquired information so that the understanding gained would be more perfect. The purpose of this research is to reveal the students' mathematical connection process in solving problems in terms of thinking style tendencies. After the data collection and data analysis process, the results obtained: subjects with Abstract Random thinking style tend to be able to go through all indicators in solving mathematical problems. Subjects with a Sequential Concrete thinking style tend not necessarily to be able to pass 1 indicator in solving mathematical problems. Subjects with an Abstract Sequential thinking style tend not necessarily to be able to pass 4 indicators and tend not to be able to go through 1 indicator in solving mathematical problems. Subjects with a Concrete Random thinking style tend not necessarily to be able to pass 5 indicators and tend not to be able to go through 1 indicator in solving math problems.
Enhancement of all-optical photoacoustic detection sensitivity via elliptical reflector
Authors: Meng Xianyu , Hong Minghui 
Published: July 2022

Abstract
All-optical photoacoustic detection has poor inspection quality when it is used on rough surfaces due to strong light scattering. We report on the use of an elliptical reflector to improve the sensitivity of all-optical photoacoustic inspection on rough surface samples. By employing the bi-focal property of the elliptical reflector, the amplitude of the photoacoustic signal can be increased by 3 times. It also greatly improves the imaging quality of photoacoustic inspection of rough surface samples. This technique has the potential to extend the applications of all-optical photoacoustic detection in industrial applications, where rough surface samples are common.

Low-Cost Shoulder Drop-off Prediction for Highways Using Learning-Based Methods

Published: July 2022

<p>One of the critical components of pavement structures are shoulders which provide lateral support to the entire pavement structure. The vertical elevation between pavement structure surface and adjacent shoulder surface results in roadway edge drop-off. Shoulder drop-off can affect the vehicle's stability and driver's ability to handle the vehicle resulting in fatalities or damage, which is also one of transportation agencies' most cited accident-related highway conditions. The maintenance staff of state transportation departments visually inspect the shoulders at near highway speeds, which might be challenging and involves human judgment, affecting the assessment's accuracy and reliability. In this work, we provide a lost-cost solution to automate the process of shoulder drop-off assessment. Our approach analyzes the point cloud data acquired from a 3D solid-state LIDAR sensor mounted on a car traveling at highway speeds. We have explored statistical, machine learning, and end-to-end deep learning methods to predict the vertical elevation of shoulder drop-off with accuracy greater than 95$\%$. We have validated the accuracy of proposed learning-based methods with actual data collected using inexpensive LIVOX LiDAR and an Astra camera along various highway sections. </p>
Design of A Doubly-Fed Linear Motor Based on Three-Phase Stator and Five-Phase Mover for High-Speed Maglev Applications

Published: July 2022

<p> The high-speed maglev train based on the doubly-fed linear motor (DFLM) has the potential advantages to achieve suspension, traction, and contactless power transfer simultaneously, which improves the reliability of the maglev system and system cost. However, there is still a lack of relevant designs of the doubly-fed linear motor to meet critical requirements for practical high-speed maglev applications, e.g., the low fluctuations of the levitation and thrust forces. In this paper, based on the performance of the German TR08 maglev train, finite element analysis (FEA) technology is used to investigate the effects of different pole-slot combinations and multi-phase winding structures on the suspension force and thrust force of the doubly-fed linear motor. A doubly-fed linear motor topology based on 36-slot 12-pole three-phase stator and 20-slot 12-pole five-phase mover is proposed, which can greatly reduce the fluctuations of suspension and thrust forces, and its performance is close to the level of TR08 maglev train. Finally, the performance of the contactless power transfer for the DFLM is analyzed. </p>
