Telur bebek merupakan salah satu jenis telur unggas yang dapat dimanfaatkan sebagai olahan makanan maupun adonan kue. Pada dasarnya kualitas telur tidak dapat bertahan lama karena adanya faktor lingkungan ataupun pada telur itu sendiri. Untuk mempertahankannya kualitas telur bebek dapat dilakukan pengawetan dengan cara diasinkan. Pengawetan dapat dilakukan secara manual tetapi membutuhkan waktu yang lama untuk proses pengasinan. Untuk mempersingkat waktu, proses pengasinan dapat dilakukan selama empat hari dengan menggunakan alat pembuat telur asin yang hanya memerlukan larutan garam dan dapat memvariasikan tingkat keasinan tergantung kadar garam, jumlah telur dan waktu yang diberikan. Proses pengasinan selama empat hari menggunakan tekanan udara yang mempercepat larutan garam masuk kedalam pori-pori telur bebek. Tekanan udara yang diberikan dapat masuk kedalam telur bebek melalui pori-pori telur sehingga udara yang masuk menjadi berkurang. Jadi, penginputan udara harus dilakukan secara kontinyu agar udara yang masuk kedalam alat konsisten.

Bahan bakar alternatif menjadi semakin penting karena penggunaan minyak bumi meningkat setiap tahun. Salah satu sumber terbarukan yang paling populer adalah minyak nabati. Minyak nabati bekas penggorengan dapat digunakan sebagai bahan baku untuk membuat bahan bakar cair. Namun, karena karakteristiknya, kemampuan pencampuran menjadi tidak cocok dengan mesin sehingga harus ditingkatkan. Banyak upaya, sehubungan dengan peningkatan karakteristik telah dilakukan berbahan baku minyak jelantah. Oleh karena itu dilakukan proses seperti microwave in-liquid plasma untuk mencapai peningkatan karakteristik dari minyak jelantah. Tujuan dari penelitian ini adalah untuk mempelajari pengaruh waktu penyalaan plasma terhadap karakteristik dari minyak jelantah, khususnya Densitas, viskositas, nilai kalor, dan titik nyala. Untuk proses tersebut, minyak jelantah 150 ml mengalami lama penyalaan plasma 1 menit, 3 menit, dan 5 menit dalam kondisi 1 atm. Hasil dari penelitian menunjukkan bahwa lama proses microwave plasma in liquid tidak memberikan pengaruh yang signifikan terhadap peningkatan karakteristik minyak jelantah. Baik itu dari nilai viskositas, densitas, maupun dari titik nyala. Nilai kalor, viskositas, dan densitas yang paling tinggi diperoleh dari minyak hasil plasma dengan waktu penyalaan 3 menit, dimana nilai kalor yang dihasilkan mencapai 36869 kJ/kg yang memiliki kenaikan nilai kalor dari bahan baku sebesar 5129 kJ/kg, viskositas yang dihasilkan adalah 59,9 cps, dan untuk densitas yang dihasilkan sebesar 0,9144 gr/ml. Viskositas dan densitas terendah ditemukan pada penyalaan plasma 1 menit, yaitu masing-masing sebesar 55,6 cst dan 0,913 gr/ml. Sedangkan untuk parameter titik nyala dari semua sampel ditemukan >210ËšC. Sedangkan nilai kalor optimal diperoleh dari waktu penyalaan plasma 3 menit, yaitu 36869 kJ/kg. Minyak hasil treatment yang diperoleh selanjutnya dapat dilakukan pengenceran untuk mengatasi nilai viskositas dan densitas.

The use of corncob powder is very wide in various industrial fields, namely as a source of dietary fiber, the basic material for making bio-plastics, partial replacement of cement in the manufacture of concrete, functional chemicals, oyster mushroom cultivation media. The most efficient method in producing corncob powder is the Ball Mill Process. The purpose of this study was to evaluate the effect of working volume and milling time on the characteristics of corn cob powder. The research procedures include specimen preparation (including cutting and drying processes) and milling processes. The results obtained were then characterized using a scanning laser microscope (LSM) to analyze the morphology and size of the product, lower working volume results in a smaller powder production with a needle-like sharp edge morphology and a higher work volume also results in a powder that has a blunt edge morphology. Although working volume can potentially be used to control particle size, this parameter has a direct effect on powder yield. As for the long milling time, it produces a smaller powder size than the faster milling time.Â

Cellular signal reception in a place must always be good, so that the services perceived by the recipient such as calls, text, and data/internet are in a stable condition. If the condition of the received signal is weak (unstable) it is necessary to improve the signal power both on the transmitter and receiver side, however, the weak signal reception occurs in a certain area with narrow coverage such as a room, house, and the like, it is necessary to strengthen the signal only at that location. In this study, I would like to propose that signal amplification is carried out by placing a passive antenna which functions to capture signals directly from the BTS, then transmits the signal to the receiver's position via cable, and the receiver brings closer or attaches the cellphone to the end of the cable. The results of the simulation and measurement research show that the parameter value of VSWR is 1.5, impedance (Z) is 75-j30.8Î©, antenna gain is 3.27 dB, bandwidth is 23 mHz. while the results of the application of the antenna in the head room of the Ujung Pandang State Polytechnic library, the antenna gain reaches 5-6 dB with a transmission cable length of 10-30 meters, cable impedance of 50 Î© and 75 Î©.

Published: June 2023

In the application of Bayesian networks to solve practical problems, it is likely to encounter the situation that the data set is expensive and difficult to obtain in large quantities and the small data set is easy to cause the inaccuracy of Bayesian network (BN) scoring functions, which affects the BN optimization results. Therefore, how to better learn Bayesian network structures under a small data set is an important problem we need to pay attention to and solve. This paper introduces the idea of parallel ensemble learning and proposes a new hybrid Bayesian network structure learning algorithm. The algorithm adopts the elite-based structure learner using genetic algorithm (ESL-GA) as the base learner. Firstly, the adjacency matrices of the network structures learned by ESL-GA are weighted and averaged. Then, according to the preset threshold, the edges between variables with weak dependence are filtered to obtain a fusion matrix. Finally, the fusion matrix is modified as the adjacency matrix of the integrated Bayesian network so as to obtain the final Bayesian network structure. Comparative experiments on the standard Bayesian network data sets show that the accuracy and reliability of the proposed algorithm are significantly better than other algorithms.
Measuring Dementia Knowledge in German: Validation and Comparison of the Dementia Knowledge Assessment Scale, the Knowledge in Dementia Scale, and the Dementia Knowledge Assessment Tool 2
Authors: Melchior Florian , Teichmann Birgit
Published: June 2023

Background: Assessing dementia knowledge is critical for developing and improving effective interventions. There are many different tools to assess dementia knowledge, but only one has been validated in German so far. Objective: To validate two tools for assessing dementia knowledge – the Dementia Knowledge Assessment Scale (DKAS-D) and the Knowledge in Dementia Scale (KIDE-D) for the German general population – and compare their psychometric properties with the Dementia Knowledge Assessment Tool 2 (DKAT2-D). Methods: A convenience sample of 272 participants completed online surveys. Analyses included internal consistency, structural validity, construct validity through the known-groups method, retest-reliability with a subgroup of n = 88, and floor and ceiling effects. This study used the STROBE checklist. Results: Internal consistency was acceptable for DKAT2-D (α= 0.780), very good for DKAS-D (α= 0.873), and poor for KIDE-D (α= 0.506). Construct validity was confirmed for all questionnaires. Retest-reliability was good for DKAT2-D (0.886; 0.825–0.926) and KIDE-D (0.813; 0.714–0.878), while it was great for DKAS-D (0.928; 0.891–0.953). Trends toward ceiling effects were observed for DKAT2-D and KIDE-D but not for DKAS-D. The principal component analysis did not reveal a coherent structure for DKAT2-D or KIDE-D, while the confirmatory factor analysis proposed the removal of 5 items for DKAS-D, resulting in the shortened DKAS20-D, which had nearly identical properties. Conclusion: Both DKAS-D and its shortened version, DKAS20-D, are reliable instruments for evaluating programs intended for the general population, as they were found to be convincing in all aspects.
The impact of parental participation on parent-child sports interaction under the background of big data and Internet of Things
Authors: Li Bowen , Qin Fangfang , Wang Hongying
Published: June 2023

With the development of society and the increase of education penetration rate, people pay more and more attention to the parent-child sports interaction between children and parents. The development of big data and the Internet of Things provides a new opportunity to study the impact of parental participation on parent-child sports interaction. This article uses technology to obtain experimental data and analyze the results of the experiment. By studying the four situations of parental participation, single parent participation, and neither parent participating, it is shown in a comparative way that parental participation can significantly improve children’s sense of experience and comprehensive ability in parent-child sports interaction. When one parent participates alone, the effect of the father’s participation is better than that of the mother. Parental participation will make children more interested in sports, and parental participation will also improve children’s abilities in all aspects. Targeted solutions are proposed based on these problems. Let fathers participate more in parent-child sports interaction, strengthen parents’ understanding of parent-child sports interaction, enrich parents’ educational experience, parents should coordinate work and life time, and choose appropriate methods for parent-child sports interaction. At present, although some achievements have been made in parent-child sports interaction, there is still a lot of room for improvement, and further research is needed.
Role of situational pedagogics in English teaching in the context of soft computing and fuzzy sets
Authors: Xu Xiang , Liu Feng , Liang Haijing
Published: June 2023

This paper improves the current situation of English language teaching from a technological perspective. Fuzzy that is a method of having local information to project the whole. Soft computing is a kind of optimization relative to traditional should computing, emphasizing the uncertainty and imprecision of things, and with the development of modern society, soft computing can solve many problems in production practice. Scenario teaching method is an important asset to enrich classroom content and mobilize students’ learning enthusiasm. Situational teaching is the sum use of preparation before class to improvisation in the classroom. It has been proved that using scenario teaching in the process of English teaching can improve students’ English ability. However, this traditional situational teaching method has problems such as incomplete evaluation index and poor teaching effect. To solve this problem, we constructed a new situational teaching method and a fuzzy evaluation system based on fuzzy sets and soft computing technology, and verified through experiments that both the new situational teaching method and the fuzzy evaluation system have good effects. At present, the popularity of situational English teaching is low, the overall level of English teaching is not high, fill-in-the-blank teaching is predominant, spoken English is weak, the cost of situational teaching is high, and teachers’ willingness to implement it is low. To improve these problems, based on the research results above we propose the following four recommendations to improve the quality of contextualized teaching, solve the problems of contextualized teaching, and reduce teachers’ pressure to prepare lessons. Finally, we make recommendations based on the current situation of the development of scenario-based teaching. (1) Build situational teaching in many ways. (2) Improve the quality of teachers’ English. (3) Develop individualized improvement programs for students. (4) Promote the reform of teaching tools.
Experimental study of continuous T-beams with negative bending moment using UHPC instead of prestressed tendons under flexure
Authors: Dong Runtao , Jia Yanmin , Guo Dongsheng
Published: June 2023

In order to explore the flexural performance of the two-span simply supported to continuous T-beam using UHPC material instead of prestressed tendons in the negative bending moment zone and the effect of the UHPC material connection length on the bearing capacity of the test beam, the flexural tests of three beams with different UHPC connection lengths were carried out. The results show that by using UHPC material instead of prestressed tendons to make continuous beams in the negative bending moment region, the tensile properties and high elastic modulus characteristics of UHPC material can be better exerted. The three test beams were all resistant to bending failure, and the cracks were distributed in the two positive and negative bending moment sections. Increasing the connection length of the UHPC material will increase the distribution range of cracks and the number of cracks in the positive moment section and the cracking load in the negative moment section. The ductility was reduced. When the connection length was increased from 300 mm to 2200 mm and 2300 mm, respectively, the bearing capacity of the test beam was increased by 4% and 6%, respectively, and the mid-span ultimate displacement was reduced by 7% and 12%, respectively. The flexural performance of the test beam was improved.
High-dimensional robust principal component analysis and its applications
Authors: Jiang Xiaobo , Gao Jie , Yang Zhongming
Published: June 2023

Principal component analysis method is one of the most widely used statistical procedures for data dimension reduction. The traditional principal component analysis method is sensitive to outliers since it is based on the sample covariance matrix. Meanwhile, the deviation of the principal component analysis based on the Minimum Covariance Determinant (MCD) estimation is significantly increased as the data dimension increases. In this paper, we propose a high-dimensional robust principal component analysis based on the Rocke estimator. Simulation studies and a real data analysis illustrate that the finite sample performance of the proposed method is significantly better than those of the existing methods.
Exploiting social context awareness for intelligent data forwarding in social Internet of Things
Authors: Deng Min , Xu Fang , Xiong Zenggang , Xu Qiong , Liu Zhen , Guo Hairu
Published: June 2023

In the social internet of things, community structure exists objectively and affects the transmission of network messages. If the social context such as community is fully utilized, the efficiency of data forwarding will be effectively improved. A community-based routing algorithm (MSAR) is proposed by studying the multiple social relationships. First, we propose four measures of social relationships. They are social closeness degree, in-community activeness, cross-community activeness and community interaction. Then, the design of routing algorithm considers two stages. One is in-community forwarding and the other is cross-community forwarding. The measurement of node forwarding capability depends on closeness degree and in-community activeness in the in-community forwarding stage. In the cross-community stage, the measurement of node forwarding capability depends on closeness degree, cross-community activeness and community interaction. The relay node with higher cross-community forwarding utility will be selected. This prevents messages from being limited to the local community. Therefore, messages can always travel in the direction of the destination node’s community. Finally, a lot of simulation experiments and analyses are carried out. The analysis results show that the proposed algorithm has good performance in the following two aspects, the average latency and the message delivery rate respectively.

Published: June 2023

A variety of measurement methods were used comprehensively in this paper to conduct empirical research on the CE, spatial pattern characteristics and influencing causes of the YREB. Both the total factor CE and the single factor CE were discovered relatively stable. Starting around 2013, the development of the tail cities of the YREB has gradually improved. In addition to Sichuan, Hunan, Chongqing, Hubei and other places where the increase in CE had exceeded that of other cities, the development of CE in Shanghai has also increased significantly. The CE of the YREB had increased with a significant positive spatial autocorrelation and a significant spatial aggregation effect between 2006 and 2017. The spatial spillover effect of CE in the YREB is mainly transmit through factors such as economic growth, energy structure, industrial structure, government intervention, population density, foreign direct investment and the level of marketization, and the spatial interaction between each factor and CE cannot be ignored.

Authors: Liao Daqiang , Zou Du , Srivastava Gautam
Published: June 2023

In this paper, an improved routing protocol for multipath network load balancing is proposed for defects in the traditional AOMDV (Ad hoc On-demand Multipath Distance Vector) protocol. This research work analyzes problems in traditional routing protocols and estimates the available path load according to network transmission in Wireless Mesh Networks (WMN). Moreover, we design a load distribution scheme according to a given load and improve multi-path load balancing by using the MCMR method. We also control path discovery and the number of paths while also establishing routing paths and probability balancing. Lastly, improvements are made to the AOMDV protocol and efficient data transmission is acheived. The performance results of the modified routing protocol show that the designed protocol can improve successful delivery rate and prolong network survival time.

BACKGROUND: Milling operations of laminae in spinal surgery generate high temperatures, which can lead to thermal injury and osteonecrosis and affect the biomechanical effects of implants, ultimately leading to surgical failure. OBJECTIVE: In this paper, a backpropagation artificial neural network (Bp-ANN) temperature prediction model was developed based on full factorial experimental data of laminae milling to optimize the milling motion parameters and to improve the safety of robot-assisted spine surgery. METHODS: A full factorial experiment design were used to analyze the parameters affecting the milling temperature of laminae. The experimental matrixes were established by collecting the corresponding cutter temperature Tc and bone surface temperature Tb for the milling depth, feed speed and different bone densities. The Bp-ANN lamina milling temperature prediction model was constructed from experiment data. RESULTS: Increasing milling depth increases bone surface and cutter temperature. Increasing feed speed had little effect on cutter temperature, but decreased bone surface temperature. Increasing bone density of laminae increased cutter temperature. The Bp-ANN temperature prediction model had best training results in the 10th epoch, and there is no overfitting (training set R= 0.99661, validation set R= 0.85003, testing set R= 0.90421, all temperature data set R= 0.93807). The goodness of fit R of Bp-ANN was close to 1, indicating that the predicted temperature was in good agreement with the experiment measurements. CONCLUSION: This study can help spinal surgery-assisted robot to select appropriate motion parameters at different density bones to improve lamina milling safety.

BACKGROUND: A multi-pod catheter (MPC) is a large drainage catheter that can house multiple smaller retractable (MPC-R) and deployable catheters (MPC-D) within the body. OBJECTIVE: The drainage capabilities and resistance to clogging of a novel MPC have been assessed. METHODS: The drainage capabilities are evaluated by placing the MPC in a bag of either a non-clogging (H2O) or clogging medium. The results are then compared to matched-size single-lumen catheters with either a close (CTC) or open tip (OTC). The means of five test runs were used to measure drainage rate, maximum drained volume (MaxDV), and time to drain the first 200 mL (TTD200). RESULTS: In the non-clogging medium, MPC-D had a slightly higher MaxDV than MPC-R, and higher flow rate than CTC and MPC-R. Moreover, MPC-D needed less TTD200 than MPC-R. In the clogging medium, MPC-D had a higher MaxDV than CTC and OTC, higher flow rate, and faster TTD200 than CTC. However, comparison with MPC-R showed no significant difference. CONCLUSION: The novel catheter may offer superior drainage compared to the single-lumen catheter in a clogging medium, implying various clinical applications, particularly when clogging is a potential risk. Further testing may be required to simulate various clinical scenarios.

Kemampuan literasi siswa Indonesia pada tahun 2018 masih berada di bawah nilai rata-rata internasional berdasarkan hasil Programme for International Student Assessment. Masih rendahnya kemampuan matematika tersebut dikarenakan siswa saat belajar di kelas hanya terbiasa mengerjakan soal prosedural. Guru memiliki peranan besar dalam membantu membangun kemampuan literasi siswa. Dapat dianologikan bahwa sebelum mahasiswa menjadi seorang guru harus memiliki kemampuan literasi matematika yang baik. Mahasiswa harus terbiasa mengerjakan soal literasi yang sesuai dengan kemampuan mereka. Perlu dilakukan suatu penelitian yang bertujuan untuk mengetahui level kemampuan literasi mahasiswa dalam menyelesaikan soal PISA. Indikator atau aspek literasi matematika yang digunakan dalam peneltian ini dikategorikan ke dalam 5 level. Jenis penelitian yang digunakan adalah deskriptif eksploratif dengan pendekatan kualitatif. Instrumen penelitian terdiri atas peneliti sendiri dan soal tes kemampuan literasi matematika yang diadopsi dari soal PISA. Subjek dalam penelitian ini adalah 9 mahasiswa program studi Pendidikan Matematika Universitas NU Kalimantan Selatan. Berdasarkan hasil penelitian diperoleh bahawa dari keseluruhan mahasiswa dapat dikelompokkan ke dalam tiga level berbeda. Satu orang masuk level 6, lima orang berada di level 4, dan 3 orang hanya memenuhi level 1. Hal ini menunjukkan secara garis besar level literasi mahasiswa prodi Pendidikan Matematika Universitas NU Kalimantan Selatan hanya sampai menjelaskan pendapatnya berdasarkan pada pemahaman, alasan dan rumusan mereka sendiri namun belum masuk ke tahap menjabarkan dan merumuskan jawabannya berdasarkan pada pemahaman dan data yang tersedia.

Problem of plane strain state of two-layer body in dynamic elastic-plastic formulation (Part I)
Authors: Bogdanov Vladislav
Published: June 2023

The design of composite and reinforced or armed materials is a requirement of the modern level of production and life. Many methods of calculation and design of such materials are successfully used. In this article, for the design of composite and reinforced materials, a technique for solving dynamic contact problems in more precise an elastic-plastic mathematical formulation is used. To consider the physical nonlinearity of the deformation process, the method of successive approximations is used, which makes it possible to reduce the nonlinear problem to a solution of the sequences of linear problems. In contrast to the traditional plane strain, when one normal stress is equal to a certain constant value, for a more accurate description of the deformation of the sample, taking into account the possible increase in longitudinal elongation, we present this normal stress as a function that depends on the parameters that describe the bending of a prismatic body that is in a plain strain state. The problem of a plane strain state of a beam made from the composite reinforced double-glazed material is being solved. The reinforced or armed material consists of two layers: the upper (first) thin layer of solid steel and the lower (second) main layer of glass. Glass is a non-crystalline, often transparent amorphous solid, that has widespread practical and technological use in the modern industry. The most familiar types of manufactured glass are "silicate glasses" based on the chemical compound silica (silicon dioxide, or quartz). Glass has high strength and is not affected by the processes of aging of the material, corrosion, and creep. In addition, this material is cheap and widely available. Glass can be strengthened, for example, in a melt quenching process. If the cooling is fast enough (relative to the characteristic crystallization time), then crystallization is prevented, and instead the disordered atomic configuration of the supercooled liquid is frozen into a solid state. This increases the strength properties of the glass. The reinforced composite beam is rigidly linked to an absolutely solid base and on which an absolutely solid impactor acts from above in the centre on a small area of initial contact.
