Sosyal medyanın birçok alanı etkilemesi ve kendisinin de bu alanlardan etkilenmesi onu ilgi çekici hale getirmektedir. Sosyal medyanın dil ve edebiyat üzerinde de olumlu-olumsuz etkilerinin olduğu görülmektedir. Dolayısıyla bu çalışmada, sosyal medyanın dil ve alışılmış edebiyat anlayışımız üzerinde nasıl bir etkiye sahip olduğu anlaşılmaya çalışılmaktadır. Sosyal medya aracılığıyla bilgiye kolay yoldan ulaşılabilmesi ve sosyal medyanın edebiyata bilgi kaynağı sağlaması edebiyat alanını olumlu etkilemektedir. Ancak bu durumda internet kaynaklı bilginin teyit edilmesi önem arz etmektedir. Bunun yanı sıra sosyal medyanın popüler olması ve aynı anda birçok kişiye ulaşılmasına imkân sağlaması, yazar ve şairlerin dikkatini çekmektedir. Sosyal medya, bu yazarlar ve şairler ile kendine özgü bir dil ve edebiyat anlayışı geliştirmektedir. Bu durumda dil ve alışılmış edebiyat anlayışımızda kırılmalar yaşandığı görülmektedir. Sanal edebiyatın gerçek edebiyatın önüne geçmeye başlaması ile edebi ürünlerin, estetikten yoksun, gerçek okuyucu kitlesinden uzak, basit ürünler olmaya başladıkları görülmektedir.

Published: June 2021

З кожним роком рух автотранспорту на дорогах стає все інтенсивнішим, що призводить до дедалі частішого виникнення заторів, особливо у містах. Затори в основному пов'язані з інтенсивним використанням приватних автомобілів, які мають переваги щодо полегшення особистої мобільності, надають відчуття безпеки та навіть підвищеного статусу. Однак вони не є ефективним засобом пасажирського транспорту, оскільки в середньому в години пік кожен пасажир особистого автомобіля викликає приблизно в 11 разів більше заторів, ніж пасажир в автобусі. Ситуація ще більше погіршується в регіонах з проблемами проектування та обслуговування доріг у містах.В статті розглянуто проблеми ефективного керування транспортними потоками в містах. Досліджено існуючі підходи до моніторингу трафіку, виявлено можливості для покращення систем моніторингу за рахунок використання штучного інтелекту.

Published: June 2021

Стаття присвячена опису моделі конволюційної нейронної мережі для покращення роздільної здатності зображень на мобільних пристроях. В наш час мобільна фотографія стає все більш і більш популярною. Багато людей вибирають у якості основного пристрою для створення фото свій смартфон, оскільки це значно зручніше, швидше та дешевше за спеціалізовану камеру. Нажаль, висока роздільна здатність і якість фото доступна лише покупцям дорогих смартфонів. Саме тому актуальною є проблема покращення роздільної здатності та чіткості фотографій є неймовірно актуальною. Традиційні алгоритми без використання машинного навчання демонструють непогані результати і не потребують великого обсягу часу, потрібного на підбір наборів даних, що необхідні для тренування нейронної мережі, та, власне, на сам процес тренування. Проте, іх ефективність та якість результату значно гірша ніж у підходів з використанням нейронних мереж. Саме тому пропонується застосувати гібридний метод обробки зображень, що базується на конволюційних нейронних мережах. Структура мережі відрізняється від класичних підходів комбінацією обробки нейронною мережею та одним з більш традиційних алгоритмів обробки зображень. Запропонавана системавикористовує конволюційні нейронні мережі замість традиційних генеративних змагальних мереж. Запропонована архітектура мережі використовує автокодувальник, який вчиться на різких зображеннях шляхом вилучення ознак. Після навчання вихідне зображення пропускається через автокодувальник. Після видалення шумів та застосування корекцій, декодер створює з цих даних необхідне різке зображення. Після обробки нейронною мережею, застосовується алгоритм Unsharp Masking з буфером глибини для покращення контрасту і яскравості результуючого зображення. У статті наведено перелік переваг використання вищезазначеної системи.

Chinese Breakthrough into Latin America
Authors: Dabagyan E.
Published: June 2021

The article deals with a number of problems associated with the growing presence of China in the Latin American continent. The author emphasizes that mutual interest is based on economic factors. In particular, the rapidly developing Chinese economy needs more raw materials and agricultural products, which are available in abundance in Latin America. At the same time, the countries of the continent are interested in freeing from orientation solely to the United States and in a diversification of external relations. The present bilateral and multilateral agreements and treaties between China and Latin America showed a strengthening of trade and economic cooperation. But Beijing's strategy is based on a model of exchange of raw materials to finished products. This causes some resentment on the part of Latin American experts and entrepreneurs.

Os distúrbios osteomusculares relacionado ao trabalho são caracterizados pelo comprometimento e desgaste das estruturas do sistema musculoesquelético, influenciado por vários fatores, que dentre eles pode-se destacar: fatores internos, externos, carga horária de trabalho e movimentos repetitivos. Esta pesquisa teve como objetivo conhecer os distúrbios osteomusculares relacionados ao trabalho em enfermeiros. Trata-se de um estudo transversal com abordagem quantitativa. A amostra foi composta por 25 enfermeiros do Hospital e Pronto Socorro 28 de Agosto, Manaus-AM. Os dados foram coletados através de um questionário aplicado aos enfermeiros, e posteriormente realizou-se análise descritiva. A prevalência dos sintomas osteomusculares foi de 56% (14), sendo que 85,7% (12) relataram que os sintomas pioravam com o exercício da enfermagem, sendo estes, casos sugestivos de distúrbios osteomusculares relacionados ao trabalho. As regiões anatômicas mais afetadas pelos sintomas foram a lombar 72%, seguida pelos ombros e pés com 68%, respectivamente. Concluiu-se que os enfermeiros entrevistados apresentavam casos sugestivos de distúrbios osteomusculares relacionados ao trabalho, pois a sintomatologia piorava com a prática da enfermagem. Deste modo, para evitar o afastamento temporário ou até mesmo definitivo destes profissionais por complicações de saúde, é necessário criar condições de trabalho adequadas que possibilitem prevenir o aparecimento dos distúrbios osteomusculares.

Published: June 2021

In this work, we pursued the biological characterization of the venom of Montivipera born-muelleri, a viper from the Lebanese mountains. In relativity to its antibacterial potential, the in-hibitory effect of this venom on the F1F0-ATPase enzymes of Gram-positive Staphylocoocus epider-midis and Gram-negative Escherichia coli bacteria was examined. In order to determine the de-gree of cytotoxicity of the venom on the HCT116 human colon cancer cell lines, the biological MTT proliferation and cell viability test were implemented. After validation of the enzymatic F1F0-ATPase model by the spectrophotometric method, using quercetin as the reference ligand, re-sults revealed that M. bornmuelleri venom is able to inhibit the activity of the enzyme of these two bacteria with a concentration of the order of 100-150 µg/mL. In addition, a venom concentration of 10 µg/mL was sufficient to kill the totality of HCT116 cell lines cultivated in vitro. These data show that M. bornmuelleri venom is a mixture of diverse molecules presenting activities of interest and is a potential source to explore in order to discover new drug candidates.

Published: June 2021

The market shares of several Muslim majority countries' Islamic banks have remained low (e.g., Malaysia, Turkey, and Indonesia) despite many Muslims. Targeted marketing can be an effective strategy to target potential customers, increase the market share, and ultimately Bank's revenue. This study firstly aims to explore potential segmentation bases for the customers of the Islamic Bank and the impact of segmentation analysis on the targeting and positioning of the Islamic Bank. This study applied an exploratory, qualitative research design. The data were collected via in-depth interviews with 30 Muslim participants using purposive sampling. The data were analyzed using inductive content analysis to find the emerged themes. The result shows that the psychographic segmentation would be more plausible to be used by the Islamic Bank than the demographic segmentation. Based on this finding, Islamic banks should consider using psychographic segmentation to target their markets.

Authors: Arribaat Salma Khoirunnisaa
Published: June 2021

One of the company's long-term goals is to maximize the firm value. It is the present value of the company, which can be a prospect in the future. Therefore, the problem in this study is the factors that affect the company's value in the Jakarta Islamic Index for 2015-2019. This study analyzes the influence of Intellectual Capital, Good Corporate Governance, and Debt to Equity Ratio on Firm Value directly and indirectly through Financial Performance. The data used in this study is panel data using purposive sampling, and there are 17 stocks listed on the Jakarta Islamic Index for 2015-2019 period. The analysis technique of this research is Partial Least Square. The test results of the direct effect show that Intellectual Capital, Debt to Equity Ratio, and Financial Performance have a significant impact on Firm Value on the Jakarta Islamic Index. Corporate governance has a substantial effect on Financial Performance. Meanwhile, indirect testing proves that the Financial Performance variable can only mediate the impact of Corporate Governance on Firm Value. However, it cannot mediate between the relationship between the variable intellectual capital and debt ratio to equity.

Published: June 2021

The aim of this study was to investigate the manifestations of headaches in adult patients with types of malocclusion and occlusion deformities. Methods and Results: The study was conducted in 171 adult patients (43 men and 128 women) with malocclusion and occlusion deformities at the age of 18 to 62 years old, who were examined in the orthopedic dentistry clinic. The nature of the dentition closing was studied directly in the patient's oral cavity, and with the help of the "Gnatomat" universal articulator on diagnostic plaster models of the jaws. The occlusal relationships of the teeth were analyzed in the position of the central, anterior, lateral and dynamic occlusions. The biomechanics of the lower jaw movements were studied in 3 mutually perpendicular directions. The detected anomalies and deformities of the occlusion were grouped as sagittal, transversal and vertical. Each group was diagnosed as independent forms of malocclusion, and combined with other anomalies and deformities of the dentoalveolar system. All the subjects were asked to answer the questions of a questionnaire specially developed for our study. The unified questionnaire was developed based on a modified rating questionnaire and the determination of the life disorders index in neck pain. The questionnaire includes blocks of questions aimed at identifying the localization of the headache in the temporal, parietal (in one or both) regions, occipital, frontal regions and in the longitudinal seam region. We identified complaints of patients with pain in adjacent regions of the head. Of the 171 examined adult patients with malocclusion and occlusion deformities, 99 (57.9%) complained of headaches. The presence of a headache in the parietal region of the head was associated most often with sagittal and transversal malocclusions. The presence of a headache in the temporal part of the head was associated often with vertical malocclusion The results of correlation analysis showed that pain in 2 regions of the head was associated with malocclusion: the temporal region (rb=0.9892, P=0.0013) and parietal region (rb=0.9712, P=0.0058). Other regions were not statistically significantly associated with malocclusion. Conclusion: There is a certain relationship between the types of malocclusion, occlusion deformities and localization of headaches in adults. Headaches in the parietal and temporal regions of the head are associated with malocclusion and occlusion deformities more often. The obtained data can serve as a basis for the development of recommendations for appropriate corrective measures in orthodontic practice.

The aim of this study was to establish normal measurements of the hemidiaphragm widths and heights in the Saudi population by a posteroanterior (PA) chest X-ray in the Mecca Region. Methods and Results: The data were collected prospectively at King Abdulaziz Hospital in Saudi Arabia, Jeddah, between March and April 2021, using a computed radiography imaging unit. A total of 45 patients (51.1% men and 48.9% women; the age range between 15 and 79 years) were included in the study. Measurements were obtained on an ideal PA chest radiograph by measuring the distance from the highest points of the right hemidiaphragm and left hemidiaphragm. The width from the right and left costophrenic angle was also measured as an ended point. The total diaphragm width (DW) was 278.32±24.83mm, the total right diaphragmatic dome height (RDDH) -51.30±10.58mm, and left diaphragmatic dome height (LDDH) - 38.40±9.21mm. The DW was greater in men than in women: 291.74±20.4mm and 264.28±21.2mm, respectively. RDDH and LDDH were also greater in men than in women: 55.4±6.77mm and 47.005±12.19mm, and 43.29±6.65mm and 33.28±8.83, respectively Conclusion: Computed radiography was useful in measuring the diaphragm because measurement points can be identified accurately and easily due to the availability of the processing system functions such as the ability to manipulate the image resolution, image contrast, and magnification.

Published: June 2021

Background: The purpose of our work was determined by the accumulation of a significant amount of experimental material under the conditions of implantation of a foreign body, a mesh implant, into the region of the anterior abdominal wall in order to obtain experimental inflammation, in which foreign body giant cells (FBGCs) were constantly visualized as reactive formations. This research aimed to study the dynamics of morphological changes in FBGCs under conditions of experimental implantation of a foreign body, a mesh implant, and the possible mechanism of their formation Methods and Results: This study was carried out on male Wistar rats, in which a foreign body was implanted—a mesh endoprosthesis made of polypropylene—in the region of the anterior abdominal wall under the aponeurosis of the rectus abdominis muscles. A section of the anterior abdominal wall with the implanted endoprosthesis was excised on Days 10, 21, 30, and 60 after surgery, fixed in 10% buffered formalin solution. The obtained samples were embedded in paraffin according to standard prescriptions; histological sections with a thickness of 5-7µm were made and stained with H&E, according to the methods of Van Gieson and Mallory, and an immunohistochemical study was performed using the marker of cell proliferation (Ki-67). The revealed structural features of multinucleated cells were recorded by microphotography using a photo attachment and a Levenhuk video camera (USA). During the study, it was revealed that the amount, functional activity and morphological diversity of FBGCs gradually increased, reaching a maximum by Day 30 of the experiment. At a later date, some of them died, while the remaining part was differentiated, splitting into small multinucleated cells and mononuclear elements, morphologically identical to macrophages and fibroblasts. The formation of FBGCs continued as long as the mesh implant was in the body. Conclusion: FBGCs are reactive formations that arise in response to various endo- and exogenous irritation.

The aim of this study was to investigate the perinatal outcomes of delivery by various methods in patients with gestational diabetes mellitus (GDM). Methods and Results: The study included 403 pregnant women (gestational age of 37.0–41.0 weeks) with GDM and 68 without disorders of carbohydrate metabolism, who gave birth from the second quarter of 2018 to the third quarter of 2020 in the maternity ward of the City Clinical Hospital No. 29 named after N.E. Bauman. All patients with GDM were divided into 2 groups. Group 1 included 187 patients receiving insulin therapy; Group 2 included 216 patients receiving a well-balanced diet. The main indicators of the health status of newborns in the early neonatal period were assessed taking into account the methods of delivery: programmed labor (PL), planned cesarean section (PCS), and spontaneous delivery. The 1-minute Apgar score in newborns from mothers of Groups 1 and 2 was higher at the PL, compared with PCS. The 5-minute Apgar score in newborns from mothers of Group 2 was also statistically significantly higher at the PL, compared with planned CS. The incidence of hypoglycemia in newborns from mothers of all groups was minimal at the PL, including a statistically significant low rate in newborns from mothers of Group 1. Symptoms of neonatal CNS depression were significantly more common in newborns born by abdominal delivery from mothers with GDM. Conclusion: PL in women with GDM reduces the incidence of the main complications of the early neonatal period: hypoglycemia and symptoms of neonatal CNS depression. PL may be considered more acceptable than abdominal delivery for women with GDM.
Heat Transfer Research in Blown-Through Non-Passable Heating Mains Channels. Part 2
Authors: Sednin V. A. , Bubyr T. V.
Published: June 2021

A schematic and structural solution of regenerative-utilization heat use  in centralized  heat supply systems was previously proposed in order to increase the efficiency of operation of heating networks located in non-passable channels. The impossibility of creating a full-scale experimental setup covering the required range of factors and the area of their change, the complexity of a passive experiment on existing heating mains led to the need to develop a virtual model based on the ANSYS sofware package. A six-factor experiment has been carried out on this virtual model. Regression equations have been obtained to determine the pressure required to provide air purging of the channel, as well as heat exchange with pipelines of direct and return network water located in the channel, and heat exchange with soil around the channel. In addition, a regression relationship has been derived to find the integral heat flux from the listed washed surfaces to the air flow. The transition from dimensionless to natural factors has been made in the paper. The most significant factors are identified with the help of Pareto cards. The obtained dependencies have been verified in Part 1 of the paper. The adequacy of the obtained regression equations has been determined using standard statistical estimation methods based on the calculated values of the Fisher’s, Student’s and other criteria. The response surfaces are presented and analyzed using two dimensional sections for a number of factor values at fixed values of one and a change in two most characteristic, physically significant for a given response function.  They have been validated on the basis of the analysis of regression dependencies. The obtained regression equations cover almost the entire range of possible diameters of heating mains, which makes it possible to use them in the development of energy-saving projects.

TiO2-based photocatalysts are a potential technology for removing indoor formaldehyde (CHOH) owing to their strong photooxidation ability. However, their photooxidation performance is generally weakened when suffering from the competitive adsorption of H2O. In a method inspired by the oxygen evolution reaction (OER) to generate intermediates with hydroxyl radicals on the anode electrode catalysts, an electric field was employed in this research and applied to the photooxidation of CHOH to prevent the competitive adsorption of H2O. Additionally, 0.5-5% Fe2O3 decorated TiO2 was employed to improve the photoelectrocatalytic activity. The influence of an electric field on hydroxyl-radical production was investigated by both density functional theory (DFT) with direct-imposed dipole momentum and photoelectrocatalytic experimental tests. The surface characterization of the photocatalysts, including transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and electron paramagnetic resonance (EPR), was conducted. DFT results show that a positive electric field with a strength of 0.05 Å/V was more favorable to produce hydroxyl on Fe2O3/TiO2(010) than was a negative electric field. Fe2O3 decoration can significantly boost hydroxyl formation, resulting from a decrease in the binding energy between the Fe of Fe2O3 and the oxygen and hydrogen atoms of H2O. The dissociated hydrogen atom of the H2O preferentially remained on the catalysts’ surface rather than being released into the gas flow. The experimental results demonstrated that the application of a low-voltage of 150 V could not directly enhance the photooxidation of CHOH by either TiO2 or Fe2O3/TiO2 but that it could relieve the H2O inhibitory effect by more than 10% on the Fe2O3/TiO2.

The management of febrile neutropenia (FN) in pediatrics is evolving. Our objective was to describe current practices for the care of patients with FN in pediatric oncology centers in Latin America and identify areas for practice improvement. We used an online survey to enroll eligible healthcare providers who treat children with cancer in Latin America. The survey addressed respondents’ characteristics, the environment of care, and FN care practices, including risk assessment, criteria for hospitalization, initial management of FN, evaluation, antibiotic administration, and discharge. From 220 surveys sent, we received 109 responses and selected 108 from 19 countries for analysis. Most (94%) respondents were working in specialized oncology centers, oncology units within a pediatric or general care hospital. The cohort included oncologists (42%) and infectious diseases physicians (30%). Most (67%) respondents had available guidelines; they used a risk-stratification scoring system (73%) for severe infection; and their guidelines had locally adapted risk stratification (34%) or published risk stratification (51%). The respondents used diverse FN definitions and concepts, including fever definitions, temperature-obtaining methods, neutropenia values for assigning risk, empiric antimicrobials administration, and length of hospitalization. Overall, we detected common practices aligning with standard published recommendations, as well as care variability. These findings can guide further evaluations of care resources and practices to prioritize interventions, and professional networks can be used for FN discussions and consensus in Latin America.
Energy Attentive and Pre-Fault Recognize Mechanism for Distributed Wireless Sensor Network Using Fuzzy Logic Approach
Authors: Talmale Roshani , Bhat Nirupama
Published: June 2021

Wireless Sensor Network (WSN) have transformed over recent years with incredible development in design of smart real time applications. In spite of countless potential, it poses numerous design issues like fault tolerant communication, low latency, scalability, transmission media and coverage problems. One of the foremost design issues of WSN is to detect the run time fault because it is unaware of internal operation of the sensor node. As a result, valuable sensed information is unable to reach its destination and performance start degrading throughout the routing period of the network. To address this issue, the proposed mechanism design a novel Pre-fault detection mechanism based on fuzzy rule based mechanism for multilevel transmission in distributed sensor networks. Many researchers have been focused on fault detection mechanisms without considering the dynamic behavior status of sensor node. In this proposed mechanism the Fuzzy decision rule set is identified to take routing decisions based on fuzzy fault count status. This mechanism helps to recognize the fault in advance and a routing decision has been taken in order to save energy as well as minimize delay. On the basis of node fault status data transmission rate is finalized in order to avoid more energy depletion. The experimented simulations results prove the accuracy of the proposed mechanism. The results demonstrate that the proposed mechanism performed well on judgment evaluation metrics such as energy dissipation ratio, packet drop rate and communication delay.

On March 12, 2020, the World Health Organization (WHO) declared COVID-19 as a global pandemic. COVID-19 is produced by a novel β-coronavirus known as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) [1]. Several studies have detected SARS-CoV-2 RNA in urine, feces, and other biofluids from both symptomatic and asymptomatic people with COVID-19 [2], suggesting that SARS-CoV-2 RNA could be detected in human wastewater [3]. Thus, wastewater-based epidemiology (WBE) is now used as an approach to monitor COVID-19 prevalence in many different places around the world [4-10]. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) is the most common SARS-CoV-2 detection method in WBE, but there are other methods for viral biomolecule detection that could work as well. The aim of this study was to evaluate the presence of SARS-CoV-2 proteins in untreated wastewater (WW) influents collected from six wastewater treatment plants (WWTPs), from Durham Region, Ontario, Canada, using a LC-MS/MS-based proteomics approach. We identified many SARS-CoV-2 proteins in these wastewater samples, with peptides from pp1ab being the most consistently detected and with consistent abundance.

Background: The development of alternative anti-angiogenesis therapy for choroidal neovascularization (CNV) remains a great challenge. Nanoparticle systems have emerged as a new form of drug delivery in ocular diseases. Here, we report the construction and characterization of arginine-glycine-aspartic acid (RGD)-conjugated polyethyleneimine (PEI) as a vehicle to load antioxidant salvianolic acid A (SAA) for targeted anti-angiogenesis therapy of CNV. In this study, PEI was consecutively modified with polyethylene glycol (PEG) conjugated RGD segments, 3-(4’-hydroxyphenyl) propionic acid-Osu (HPAO), and fluorescein isothiocyanate (FI), followed by acetylation of the remaining PEI surface amines to generate the multifunctional PEI vehicle PEI.NHAc-FI-HPAO-(PEG-RGD) (for short, RGD-PEI). The formed RGD-PEI was utilized as an effective vehicle platform to load SAA. Results: We showed that RGD-PEI/SAA complexes displayed desirable water dispersibility, low cytotoxicity, and sustainable release of SAA under different pH conditions. It could be specifically taken up by ɑvβ5 integrin receptors expressing retinal pigment epithelium (RPE) cells in vitro and selectively accumulated in CNV lesions in vivo. Moreover, the complexes displayed specific therapeutic efficacy in a mouse model of laser induced CNV, and the slow elimination of the complexes in the vitreous cavity was verified by SPECT imaging after 131I radiolabeling. The histological examinations further confimed the biocompatibility of RGD-PEI/SAA.Conclusions: The results suggest that the designed RGD-PEI/SAA complexes may be a potential alternative anti-angiogenesis therapy for posterior ocular neovascular diseases.

Published: June 2021

Background: Overexpression of microRNA-93 (miR-93) predicted worse outcome in non-small cell lung cancer (NSCLC) and gastric cancer patients, yet the prognostic role of miR-93 in AML is still unclear.Methods: To further verify the prognostic significance of miR-93, the Cancer Genome Atlas database (TCGA) was screened and 161 AML patients with miR-93 expression information were included in our study.Results: Compared with the patients who received chemotherapy alone with lower miR-93 expression, those with higher miR-93 expression had significantly longer event-free survival (EFS) and overall survival (OS) (all P < 0.05). Moreover, the expression levels of miR-93 was no association with either EFS or OS in patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). Multivariate analysis confirmed that high miR-93 expression was an independent favorable factor for EFS and OS in AML patients only receiving chemotherapy (all P < 0.05).Conclusion: our study proved that high miR-93 expression could predict favorable prognosis in AML, but its prognostic effect could be overcome by allo-HSCT.

Published: June 2021

A tellurite photonic crystal fiber (PCF) sensor structure is proposed for simultaneous measurements of the methane and hydrogen. The structure is a simple hexagonal three-cladding structure, and six air holes in the inner cladding are coated with methane-sensitive film and hydrogen-sensitive film respectively. Based on the degenerate four-wave mixing (DFWM) theory, the direct relationship between the wavelength shifts of Stokes spectrum or anti-Stokes spectrum and the variations of gas concentration can be established to realize the accurate detection of gas concentration. The influences of pump wavelength and gas-sensitive film thickness on the gas sensitivity are investigated, and the maximum sensitivity of methane and hydrogen after parameter optimization are -2.052nm/% and -0.236nm/%, respectively. The linearity of the fitting can reach up to 99.95%, and the low detection limit of methane is 450ppm and hydrogen is 2500ppm. The sensing method based on four-wave mixing in non-silica photonic crystal fiber also can be extended to other detections of gas-mixture in the mid-infrared field.

One of the most widely used antibiotics is amoxicillin (AMX), which is the most widely used in humans and animals, but it is discharged metabolically due to its indigestibility. Conventional biological and physicochemical methods for removing AMX from water are not enough to mineralize it, only it is concentrated and transferred to produce new residues that require further processing to remove the new residues.In this research, naked and modified surfaces with TiO2 nanotubes (TiO2,nt) electrophoretically modified with PbO2, IrO2, RuO2, and Ta2O5 were used to evaluate their efficiency in the electrochemical degradation of AMX in acid media (0.1 mol L− 1 H2SO4). After their comparison, Pb-Ta 50:50|TiO2,nt|Ti showed the highest removal efficiency of AMX (44.71 %) with the lowest specific energy consumption (8.69 ± 0.78 kWh Kg COD− 1), and the average instant current efficiency of 26.67 ± 9.19 %, in comparison with the others naked and modified surfaces of TiO2,nt|Ti.
Fog Computing Application of Cyber-Physical Models of IoT Devices with Symbolic Approximation Algorithms
Authors: Choi Deok-Kee
Published: June 2021

Smart manufacturing systems transmit out streaming data from IoT devices to cloud computing; however, this could bring about several disadvantages such as high latency, immobility, and high bandwidth usage, etc. As for streaming data generated in many IoT devices, to avoid a long path from the devices to cloud computing, Fog computing has drawn in manufacturing recently much attention. This may allow IoT devices to utilize the closer resource without heavily depending on cloud computing. In this research, we set up a three-blade fan as IoT device used in manufacturing system with an accelerometer installed and analyzed the sensor data through cyber-physical models based on machine learning and streaming data analytics at Fog computing. Most of the previous studies on the similar subject are of pre-processed data open to public on the Internet, not with real-world data. Thus, studies using real-world sensor data are rarely found. A symbolic approximation algorithm is a combination of the dictionary-based algorithm of symbolic approximation algorithms and term-frequency inverse document frequency algorithm to approximate the time-series signal of sensors. We closely followed the Bayesian approach to clarify the whole procedure in a logical order. In order to monitor a fan's state in real time, we employed five different cyber-physical models, among which the symbolic approximation algorithm resulted in about 98% accuracy at a 95% confidence level with correctly classifying the current state of the fan. Furthermore, we have run statistical rigor tests on both experimental data and the simulation results through executing the post-hoc analysis. By implementing micro-intelligence with a trained cyber-physical model unto an individual IoT device through Fog computing we may alienate significant amount of load on cloud computing; thus, with saving cost on managing cloud computing facility. We would expect that this framework to be utilized for various IoT devices of smart manufacturing systems.
