Abstract (sommario):

O trabalho aqui apresentado tem como objetivo demonstrar o sucesso de um paciente submetido a cirurgia de estabilização ventral através de parafusos e cimento ósseo. Clinicamente a cadela se apresentava tetraparética e com quadro progressivo de piora, com dor, comprometimento respiratório e cegueira, o que fez a decisão cirúrgica ser de extrema importância, pois há grande chance de óbito nesses casos. A instabilidade é mais comum em cães de raças pequenas, mas há relatos em cães de porte grande ou até mesmo em gatos (raro). As formas podem ser congênitas ou adquiridas e os animais acometidos podem apresentar sinais clínicos agudos ou crônicos, desde tetraparesia ambulatória leve com dor até alterações respiratórias graves. O diagnóstico é obtido pela associação dos exames físico, neurológico e de imagem como radiografia, tomografia computadorizada e ressonância magnética. A possibilidade de tratamento depende de alguns fatores, mas pode ser conservativo ou, como no relato descrito, cirúrgico, o qual tem duas formas de abordagem, a ventral e a dorsal. O presente relato trata de um canino, fêmea da raça poodle que foi acompanhada clinicamente por dois anos após a cirurgia, sem que houvesse recidiva dos sinais clínicos ou prejuízo do quadro neurológico.

Government regulations impose physical distancing for all students. Students and workers are required to stay at home. At SD Negeri Pedurungan Kidul 02 Semarang, they must comply with the regulations that apply during the pandemic. This has resulted in the emergence of several difficulties for work that must be carried out online. One of them is in education, and a teacher must be able to carry out teaching activities online. This can be considered a major obstacle for a technology-blind teacher so that the delivery and evaluation of the material cannot be conveyed properly. Some teachers need additional skills regarding the use of technology to help implement online teaching from the above problems. The implementation of this socialization is focused on conducting evaluations with online media using the google form application, google sites, google Lens, google expedition AR and VR. The implementation of this activity has received a positive response from the participants. This result can be seen from the questionnaire results obtained by the pre-test and post-test for each PKM training and mentoring participant question, which has increased from 28.58% to 91.55% for Yes questions. Thus this training can increase the ability to use and utilize Google's features.

Abstract (sommario):

We present the first measurement of the left-right cross-section asymmetry (A LR ) in Z-boson production observed at the SLAC Linear Collider. In 1992 the SLD detector recorded 10 224 Z events produced by the collision of longitudinally polarized electrons with an unpolarized positron beam at a center-of-mass energy of 91.55 GeV. The average electron beam polarization during the run was (22.4 ± 0.6)%. We measure A LR to be 0.100 ± 0.0440 (stat.) ±0.004 (syst.) , which determines the effective weak mixing angle to be [Formula: see text].

The Vector Autoregressive Model (VAR) is a very useful analytical tool in understanding the existence of interrelationships between economic variables and in the formation of a structured economy. This study aims to explain the analysis of the Vector Autoregressive (VAR) model and explain the application of the Vector Autoregressive (VAR) model for influence analysis. The FDR ratio in the Sharia Commercial banks tends to be stable. This is illustrated from the coefficient of determination which is almost close to 100%, namely 91.55%. Cointegration test results show there is no long-term balance relationship between FDR variables with ROA of Islamic banks in Indonesia. ROA has a positive effect on ROA while ROA on FDR is negative, meaning that FDR makes a small contribution to ROA.

Abstract (sommario):

The Fe3O4 and Fe2SiO4 in copper slag were successfully reduced to metallic iron by coal-based direct reduction. Under the best reduction conditions of 1300 °C reduction temperature, 30 min reduction time, 35 wt.% coal dosage, and 20 wt.% CaO dosage (0.75 binary basicity), the Fe grade of obtained iron concentration achieved 91.55%, and the Fe recovery was 98.13%. The kinetic studies on reduction indicated that the reduction of copper slag was controlled by the interfacial reaction and carbon gasification at 1050 °C. When at a higher reduction temperature, the copper slag reduction was controlled by the diffusion of the gas. The integral kinetics model research illustrated that the reaction activation energy increased as the reduction of copper slag proceeded. The early reduction of Fe3O4 needed a low reaction activation energy. The subsequent reduction of Fe2SiO4 needed higher reaction activation energy compared with that of Fe3O4 reduction.

Abstract (sommario):

In this study, the occurrence of Cochlodinium polykrikoides bloom was predicted based on spatial information. The South Sea of Korea (SSK), where C. polykrikoides bloom occurs every year, was divided into three concentrated areas. For each domain, the optimal model configuration was determined by designing a verification experiment with 1–3 convolutional neural network (CNN) layers and 50–300 training times. Finally, we predicted the occurrence of C. polykrikoides bloom based on 3 CNN layers and 300 training times that showed the best results. The experimental results for the three areas showed that the average pixel accuracy was 96.22%, mean accuracy was 91.55%, mean IU was 81.5%, and frequency weighted IU was 84.57%, all of which showed above 80% prediction accuracy, indicating the achievement of appropriate performance. Our results show that the occurrence of C. polykrikoides bloom can be derived from atmosphere and ocean forecast information.

Abstract (sommario):

In recent years, deep learning (DL) based systems have become very popular for constructing hierarchical representations from unlabeled data. Moreover, DL approaches have been shown to exceed foregoing state of the art machine learning models in various areas, by pattern recognition being one of the more important cases. This paper applies Convolutional Deep Belief Networks (CDBN) to textual image data containing Arabic handwritten script (AHS) and evaluated it on two different databases characterized by the low/high-dimension property. In addition to the benefits provided by deep networks, the system is protected against over-fitting. Experimentally, the authors demonstrated that the extracted features are effective for handwritten character recognition and show very good performance comparable to the state of the art on handwritten text recognition. Yet using Dropout, the proposed CDBN architectures achieved a promising accuracy rates of 91.55% and 98.86% when applied to IFN/ENIT and HACDB databases, respectively.

Abstract (sommario):

In the hazelnut oil production it is very important to find an appropriate method to recover the oil from kernels. The objective of this study was to evaluate the oil extraction process from hazelnuts by screw pressing followed by extraction with supercritical CO2. The effects of temperature head presses, frequency and nozzle size in pressing experiments on oil temperature and recovery were monitored. The optimal pressing condition using response surface methodology was determined. In obtained hazelnut oil the following quality parameters were determined: peroxide value 0 mmol O2/kg, free fatty acids 0.23%, insoluble impurities 0.42%, moisture content 0.045%, iodine value 91.55 g I2/100 g, saponification value 191.46 mg KOH/g and p-anisidine value 0.19. Rosemary extract was the most effective in protecting the oil from oxidative deterioration. The residual oil that remained in the cake after pressing was extracted totally with supercritical CO2 and such defatted cake, free of toxic solvents, can be used further in other processes.

Abstract (sommario):

This article is driven by three goals. The first is to use machine learning to predict tree cover types, helping to address current challenges faced by U.S. forest management agencies. The second is to bring previous research in the area up-to-date, owing to a lack of development over time. The third is to improve on previous results with new data analysis, higher accuracy, and higher reliability. A Deep Neural Network (DNN) was constructed and compared with three baseline traditional machine learning models: Naïve Bayes, Decision Tree, and K-Nearest Neighbor (KNN). The neural network model achieved 91.55% accuracy while the best performing traditional classifier, K-Nearest Neighbor, managed 74.61%. In addition, the neural network model performed 20.97% better than the past neural networks, which illustrates both advances in machine learning algorithms, as well as improved accuracy high enough to apply practically to forest management issues. Using the techniques outlined in this article, agencies can cost-efficiently and quickly predict tree cover type and expedite natural resource inventorying.

Abstract (sommario):

In intelligent surveillance of construction sites, safety helmet detection is of great significance. However, due to the small size of safety helmets and the presence of high levels of noise in construction scenarios, existing detection methods often encounter issues related to insufficient accuracy and robustness. To address this challenge, this paper introduces a new safety helmet detection algorithm, FEFD-YOLOV5. The FEFD-YOLOV5 algorithm enhances detection performance by adding a shallow detection head specifically for small target detection and incorporating an SENet channel attention module to compress global spatial information, thus improving the model’s mean average precision (mAP) in corresponding scenarios. Additionally, a novel denoise module is introduced in this algorithm, ensuring the model maintains high accuracy and robustness under various noise conditions, thereby enhancing the model’s generalization capability to meet real-world scenario demands. Experimental results show that the proposed improved algorithm achieves a detection accuracy of 94.89% in noiseless environments, and still reaches 91.55% in high-noise environments, demonstrating superior detection efficacy compared to the original algorithm.

Abstract (sommario):

Traditional digital camouflage is mainly designed for a single background and state. Its camouflage performance is appealing in the specified time and place, but with the change of place, season, and time, its camouflage performance is greatly weakened. Therefore, camouflage technology, which can change with the environment in real-time, is the inevitable development direction of the military camouflage field in the future. In this paper, a fast-self-adaptive digital camouflage design method based on deep learning is proposed for the new generation of adaptive optical camouflage. Firstly, we trained a YOLOv3 model that could identify four typical military targets with mean average precision (mAP) of 91.55%. Secondly, a pre-trained deepfillv1 model was used to design the preliminary camouflage texture. Finally, the preliminary camouflage texture was standardized by the k-means algorithm. The experimental results show that the camouflage pattern designed by our proposed method is consistent with the background in texture and semantics, and has excellent camouflage performance in optical camouflage. Meanwhile, the whole pattern generation process takes a short time, less than 0.4 s, which meets the camouflage design requirements of the near-real-time camouflage in the future.

Abstract (sommario):

This study investigated the combination of two kinds of autotrophic bacteria, named Anammox and Nitrosomonas in a reactor to remove ammonium existed in swine wastewater. The reactor which was operated with swine wastewater taken from Dong A pig breeding enterprise (Di An, Binh Duong) had 15 liters volume. The biomass carrier used in this model was made from the synthetic acrylic with attached capacity of 0.5-0.6g-SS/g-material. The sludge was taken from a reactor using partial nitritation/Anammox processes of a previous study at Vietnam Academy of Science and Technology. In 118 days of operation, average influent ammonium was 350mg/l, feeding to three loading rates (LR) 0.47, 0.70, 0.93 kg N-NH4+/m3/day with flow rate 20, 30, 40 liters, respectively. The highest efficiency was found at the first loading rate 0.47 kg N-NH4+/m3/day with 91.55 %. The other loading rates 0.70 and 0.93 kg N-NH4+/m3/day gave lower efficiency, 78.08 and 70.5 %, respectively. VSS at the beginning and the end of the operation were 4g/l and 9.4 g/l, respectively. The optimum pH for the reactor was in range of 7.8 - 8.0.

Abstract (sommario):

We propose an algorithm for vessel extraction in retinal images. The first step consists of applying anisotropic diffusion filtering in the initial vessel network in order to restore disconnected vessel lines and eliminate noisy lines. In the second step, a multiscale line-tracking procedure allows detecting all vessels having similar dimensions at a chosen scale. Computing the individual image maps requires different steps. First, a number of points are preselected using the eigenvalues of the Hessian matrix. These points are expected to be near to a vessel axis. Then, for each preselected point, the response map is computed from gradient information of the image at the current scale. Finally, the multiscale image map is derived after combining the individual image maps at different scales (sizes). Two publicly available datasets have been used to test the performance of the suggested method. The main dataset is the STARE project’s dataset and the second one is the DRIVE dataset. The experimental results, applied on the STARE dataset, show a maximum accuracy average of around 94.02%. Also, when performed on the DRIVE database, the maximum accuracy average reaches 91.55%.

Abstract (sommario):

Rolling element bearings are used in all rotating machinery, and the degradation performance of rolling element bearings directly affects the performance of the machine. Therefore, high reliability prediction of the performance degradation trend of rolling element bearings has become an urgent research problem. However, the degradation characteristics of the rolling element bearings vibration time series are difficult to extract, and the mechanism of performance degradation is very complicated. The accurate physical model is difficult to establish. In view of the above reasons, based on the vibration performance data of rolling element bearings, a model of bearing performance degradation trend parameter based on wavelet denoising and Weibull distribution is established. Then, the phase space reconstruction of the series of bearing performance degradation trend parameter is carried out, and the prognosis is obtained by the improved adding weighted first-order local prediction method. The experimental results show that the bearing vibration performance degradation parameter can accurately depict the degradation trend of the bearing, and the reliability level is 91.55%; and the prediction of bearing performance degradation trend parameter is satisfactory: the mean relative error is only 0.0053% and the maximum relative error is less than 0.03%.

Abstract (sommario):

This study is to analyze the influence of visibility in a foggy weather environment on the accuracy of machine vision obstacle detection in assisted driving. We present a foggy day imaging model and analyze the image characteristics, then we set up the faster region convolutional neural network (Faster R-CNN) as the basic network for target detection in the simulation experiment and use Karlsruhe Institute of Technology and Toyota Technological Institute (KITTI) data for network detection and classification training. PreScan software is used to build weather and traffic scenes based on a foggy imaging model, and we study object detection of machine vision in four types of weather condition—clear (no fog), light fog, medium fog, and heavy fog—by simulation experiment. The experimental results show that the detection recall is 91.55%, 85.21%, 72.54~64.79%, and 57.75% respectively in no fog, light fog, medium fog, and heavy fog environments. Then we used real scenes in medium fog and heavy fog environment to verify the simulation experiment. Through this study, we can determine the influence of bad weather on the detection results of machine vision, and hence we can improve the safety of assisted driving through further research.

Abstract (sommario):

In this study, a combination of petrographic and major element geochemical methods was employed on sandstones and shales of Upper Devonian Ilanqareh Formation, northwest of Iran, aimed at investigating the tectonic setting and the weathering degree of rocks in the source area. The index of compositional variability (ICV below 1) indicated that the studied quartzarenite and subarkose sandstones were not in the first cycle. Petrographic studies showed the existence of a craton interior provenance for these sandstones and geochemical studies identified recycling of older formations as an important source of these deposits. The chemical index of alteration (CIA values of 78.18 to 90.42 for sandstones and 91.55 to 91.93 for shale samples) indicated that the samples were affected by the high degree of weathering due to the humid climate in the source areas. Geochemical discrimination diagrams revealed that the samples were deposited in a passive margin. According to the paleogeography, this passive margin was the margin of a rift basin in the northwest of Gondwana, and the Ilanqareh deposits were derived from the Arabian-Nubian shield and the recycling of the Lower Palaeozoic sandstones in the region.

Abstract (sommario):

This work was carried out in the departments of Guidan Roumji (Karazomé and Karo Sofoua), Madaroumfa (Safo and Bargaja) and Dakoro (Baban Kori and Akora Idi) in the Maradi region. The objective was to identify the different methods of conservation of agricultural by-products in rural areas. In order to achieve this objective, a sample of 296 farmers was surveyed out of the 300 planned, chosen on the basis of the simple random type probabilistic method. The results show that 98.64% use the conservation of agricultural by-products. These residues are mainly cowpea haulms (96.29%), sorghum straw (91.55%), groundnut haulms (85.82%) and millet straw (80.4%). The most dominant conservation methods are the hayloft (78.38%), on the open-air shed (58.11%) which are observed in all the villages. It appears from this work that the smallholder farmers attach great importance to the conservation of crop residues in the study area. Nevertheless, this conservation of agricultural by-products is done in a traditional way. It is therefore necessary to train smallholder farmers on the conservation of crop residues used in animal feed. This will allow more rational management and better conservation of the nutritive value of crop residues.

Abstract (sommario):

This present study is targeted at the complex investigation of the behavior of interpolymer systems based on acidic rarely crosslinked polymeric hydrogels (polyacrylic acid hydrogel (hPAA); polymethacrylic acid hydrogel (hPMAA)) and basic rarely crosslinked polymeric hydrogels (poly-4-vinylpyridine hydrogel (hP4VP), specifically the poly-2-methyl-5-vinylpyridine hydrogel (hP2M5VP)) either in an aqueous medium or lanthanum nitrate solution. We found that the transition of the polymeric hydrogels in the developed interpolymer systems (hPAA-hP4VP, hPMAA-hP4VP, hPAA-hP2M5VP, and hPMAA-hP2M5VP) into highly ionized states leads to significant changes in electrochemical, conformational, and sorption properties of the initial macromolecules. The subsequent mutual activation effect demonstrates strong swelling of both hydrogels in the systems. The sorption efficiency of lanthanum by the interpolymer systems is 94.51% (33%hPAA:67%hP4VP), 90.80% (17%hPMAA-83%hP4VP), 91.55% (67%hPAA:33%hP2M5VP), and 90.10% (50%hPMAA:50%hP2M5VP). An advantage of the interpolymer systems (compared to individual polymeric hydrogels) is the strong growth of their sorption properties (up to 35%) due to high ionization states. Interpolymer systems can be considered new-generation sorbents for further application in the industry for highly effective sorption of rare earth metals.

Abstract (sommario):

In modern education, mental health problems have become the focus and difficulty of students’ education. Painting therapy has been integrated into the school’s art education as an effective mental health intervention. Deep learning can automatically learn the image features and abstract the low-level image features into high-level features. However, traditional image classification models are prone to lose background information, resulting in poor adaptability of the classification model. Therefore, this article extracts the lost colour of painting images based on K-means clustering and proposes a painting style classification model based on an improved convolutional neural network (CNN), where a modified Synthetic Minority Oversampling Technique (SMOTE) is proposed to amplify the data. Then, the CNN network structure is optimized by adjusting the network’s vertical depth and horizontal width. Finally, a new activation function, PPReLU, is proposed to suppress the excessive value of the positive part. The experimental results show that the proposed model has the highest accuracy in classifying painting image styles by comparing it with state-of-the-art methods, whose accuracy is up to 91.55%, which is 8.7% higher than that of traditional CNN.
