ANALISA PANEL ATS DAN AMF GENSET SECARA AUTOMATIS PADA INDUSTRI
Authors: A.S Nizar Rosyidi , Prakoso Faris Izhan , Supriyadi Edy
Published: March 2024

PLN sebagai sumber utama listrik pada suatu bangunan, gedung maupun indutri sekalipun tidak selamanya continue dalam penyalurannya sehingga dibutuhkan generator set (genset) sebagai back-up suplai utama (PLN). Sebagai kontrol genset mengambil alih suplai tenaga listrik ke beban ataupun sebaliknya maka diperlukan sistem kontrol otomatis yang biasanya disebut Automatic Transfer Switch (ATS) dan Automatic Main Failure (AMF) atau sistem interlok PLN – Genset. Untuk memfasilitasi peralihan beban listrik dari PLN ke Genset dan sebaliknya perlu dirancang bangun panel ATS dan AMF. Panel ini berfungsi mengalihkan daya listrik secara otomatis dari PLN ke Genset ketika sumber listrik dari PLN mengalami pemadaman. Seperti pada umumnya panel ATS dan AMF, sistem interlok PLN - Genset memiliki dua mode operasi transfer atau pemindahan beban yaitu secara manual dan otomatis. Sedangkan fungsi utama saat operasi otomatis ATS dan AMF sebagai kontrol utama emergency power yaitu memonitoring dan sensoring catu daya utama (PLN), jika PLN mengalami pemadaman maka modul dse 4520 MKII akan memberikan perintah kepada genset untuk melakukan starting genset, apabila genset telah starting dan running maka modul dse 4520 MKII akan memonitoring tegangan, ampere, frekuensi yang dihasilkan oleh genset. Pengambilan data dan penelitian analisa tersebut dilakukan di industri yang bergerak di bidang perakitan panel listrik dan pekerjaan instalasi listrik dengan metode tanya jawab dengan teknisi yang sudah berpengalaman. Hasil dari penelitian ini adalah 1) Menganalisa pengujian waktu dan proteksi genset 2) Dan mengetahui hasil dari setting waktu dan proteksi genset pada modul dse 4520 MKII seperti saat PLN padam lalu genset start dan pengaman saat beban lebih pada genset

Authors: Irmayani Irmayani , Saputra Aulia Fikri , Putra Faisal Ramadhan
Published: March 2024

Selain pengguna SIM card pascabayar (postpaid), banyak diantara pelanggan yang sedang roaming di jaringan internasional adalah pengguna SIM card prabayar (prepaid). Salah satu layanan yang paling sering digunakan oleh roamers adalah Mobile Originating Call (MOC). Pada nomor prepaid terdapat perbedaan dalam proses panggilan terutama outgoing call karena menggunakan logic tertentu pada saat pembangunan panggilan. Implementasi Customized Applications for Mobile network Enhanced Logic (CAMEL) bertujuan untuk mengakomodasi setiap nomor prepaid agar dapat melakukan aktivitas MOC ketika roaming di jaringan internasional. Sebelum dilakukan implementasi CAMEL, pelanggan prepaid masih bisa melakukan MOC akan tetapi harus menggunakan layanan USSD Callback. Layanan USSD Callback ini kurang efektif bagi pelanggan. Setelah dilakukan implementasi CAMEL, akan dilihat tingkat performansi dengan mengambil log transaksi location update dan MOC oleh pelanggan prepaid yang roaming di jaringan internasional. Hasil yang didapat setelah implementasi CAMEL adalah persentase LUSR mencapai 73%, masih termasuk ke dalam kategori Good pada kualitas standard KPI operator. Sedangkan persentase CCR untuk transaksi MOC adalah 55%, termasuk kategori Fair pada kualitas standard KPI operator karena masih di atas 50%. Jadi hasil yang didapat adalah sudah memenuhi standard dari keseluruhan operator lokal yang memiliki kerjasama international roamingdengan operator Roaming Partner.

Transient MHD Fluid Flow Past a Moving Vertical Surface in a Velocity Slip Flow Regime
Authors: Okuyade Ighoroje W. A. , Abbey Tamunoimi M.
Published: March 2024

The problem of unsteady MHD fluid flow past a moving vertical surface in a slip flow regime is presented. The model is built on the assumption that the flow is naturally convective with oscillating time-dependent and exponentially decaying suction and permeability, double-diffusion, viscous dissipation, and temperature gradient-dependent heat source, and non-zero tangential velocity at the wall; the fluid is viscous, incompressible, Newtonian, chemically reactive, and magnetically susceptible; the surface is porous, and electrically conductive, and thermally radiative. The governing partial differential equations are highly coupled and non-linear. For easy tractability, the equations are reduced to one-dimensional using the one-dimensional unsteady flow theory. The resulting equations are non-dimensionalized and solved using the time-dependent perturbation series solutions, and the Modified Homotopy Perturbation Method (MHPM). The solutions of the concentration, temperature, velocity, rates of mass and heat diffusion, and wall shear stress are obtained, computed, and presented graphically and quantitatively, and analyzed. The results among others, show that the increase in the: Schmidt number increases the fluid concentration, velocity, the rate of heat transfer to the fluid, and the stress on the wall, but decreases the rate of mass transfer to the fluid; Magnetic field parameter decreases the fluid velocity and stress on the wall; Slip parameter increases the flow velocity, but decreases the stress on the wall; Permeability parameter increases the flow velocity and the stress on the wall. These results are benchmarked with the reports in existing literature and they agree.

TEACHING STRATEGIES IN SWIMMING AND AQUATICS
Authors: Bailon Lyndon
Published: March 2024

Research-based instructional materials, such as course manuals, should be used to optimize the performance of instructors teaching swimming and aquatics. This study used an exploratory research design to explore the teaching strategies and challenges of ten swimming and aquatic course instructors at Bicol University through survey interviews and curriculum analysis. The study revealed that the instructors used various teaching approaches in the course, depending on the topic. Major challenges were poor facilities, overcrowded pools, and a lack of professional development. A course manual covering the eight topics of the course was developed. The manual was evaluated and scored as acceptable for use in teaching the course. It was concluded that the techniques for implementing theory-based learning and the difficulties that educators face may serve as the foundation for the development of successful teaching resources, such as books and manuals. Strong institutional support for providing adequate facilities and professional development for instructors is recommended. Use of the manual developed here is encouraged to evaluate its effectiveness.
ACE-DNV: Automatic classification of gaze events in dynamic natural viewing
Authors: Nejad Ashkan , de Haan Gera A. , Heutink Joost , Cornelissen Frans W.
Published: March 2024

Eye movements offer valuable insights for clinical interventions, diagnostics, and understanding visual perception. The process usually involves recording a participant’s eye movements and analyzing them in terms of various gaze events. Manual identification of these events is extremely time-consuming. Although the field has seen the development of automatic event detection and classification methods, these methods have primarily focused on distinguishing events when participants remain stationary. With increasing interest in studying gaze behavior in freely moving participants, such as during daily activities like walking, new methods are required to automatically classify events in data collected under unrestricted conditions. Existing methods often rely on additional information from depth cameras or inertial measurement units (IMUs), which are not typically integrated into mobile eye trackers. To address this challenge, we present a framework for classifying gaze events based solely on eye-movement signals and scene video footage. Our approach, the Automatic Classification of gaze Events in Dynamic and Natural Viewing (ACE-DNV), analyzes eye movements in terms of velocity and direction and leverages visual odometry to capture head and body motion. Additionally, ACE-DNV assesses changes in image content surrounding the point of gaze. We evaluate the performance of ACE-DNV using a publicly available dataset and showcased its ability to discriminate between gaze fixation, gaze pursuit, gaze following, and gaze shifting (saccade) events. ACE-DNV exhibited comparable performance to previous methods, while eliminating the necessity for additional devices such as IMUs and depth cameras. In summary, ACE-DNV simplifies the automatic classification of gaze events in natural and dynamic environments. The source code is accessible at https://github.com/arnejad/ACE-DNV.
Импликативные вопросы и семантика Хэмблина
Authors: Zimmerling A.
Published: March 2024

This paper takes a stand on Hamblin semantics and its relation to the semantics-to-pragmatics interface. Biased questions, where the speaker finds one of the options more likely and expects the confirmation that p is true, raise a concern about the limits of Hamblin semantics. I argue that biased questions have modified Hamblin semantics, while unbiased questions have unconstrained Hamblin semantics. The optional bias feature explains compositionally. It is triggered by likelihood presuppositions ranging Hamblin sets and highlighting the preferred alternative(s). Biased effects are exceptionally possible in alternative and wh-questions, but only in polar questions, they can be encoded lexically and grammatically. I argue that Hamblin semantics covers all core types of questions, while some of its applications for non-questions are problematic.

В статье оценивается модель вопросов, известная как семантика Хэмблина, и ее роль для семантико-прагматического интерфейса. Импликативные вопросы, где говорящий предрасположен принять один из ответов и ждет от слушателя подтверждения, что p истинно, важны для оценки применимости модели Хэмблина. Приводятся аргументы в пользу того, что импликативные вопросы реализуют модифицированную семантику Хэмблина, в то время как нейтральные да-нет вопросы реализуют базовую семантику Хэмблина в неосложненном виде. Импликативность как компонент значения вопроса может быть объяснена композиционально. Имеется класс выражений, вводящих пресуппозиции о разной степени вероятности альтернатив, эти выражения могут сочетаться с операторами вопроса и маркерами верификации. Прагматические эффекты, сходные с импликативностью, маргинально возможны в альтернативных вопросах и вопросах с вопросительным словом, но лишь в да-нет вопросах они могут быть закреплены в структуре предложения. Все основные типы вопросов могут быть описаны семантикой Хэмблина, но ее экстраполяция на другие типы высказываний не всегда продуктивна.

Published: March 2024

This study aims to evaluate the accounting information system for receiving tuition fees as an internal control tool for cash receipts at St. Catholic High School. Albertus Malang. This research is a case study research. The data used are qualitative and quantitative data. Primary data sources and secondary data are obtained from research reports, documents, and other supporting data sources.

The problem that occurs is that the internal control of cash receipts from payment of tuition fees is still weak. This is due to the absence of an application document for the relief of SPP fines for depositors who are late in making SPP payments and are unable to pay the nominal SPP fines collected.

The results of a qualitative descriptive analysis are by adding documents in the form of an application letter for the relief of SPP fines and improving the systems and procedures for cash receipts for SPP fines. This can optimize internal control to run effectively.

ABSTRACT

Determining risk factors for death when early resuscitation of septic shock patients under monitoring by the PiCCO system

Background: Septic shock has high mortality rate. The early collaborating of the Pulse Contour Cardiac Output (PiCCO) system to monitor and treat septic shock quickly achieving target blood pressure can consequently reduce organ failure and increase survival rate. This study aims to determine time to vasopressor discontinuation and the mortality rate when combining CRRT and early hemodynamic resuscitation under monitoring by the PiCCO system, and explore the risk factors for death.

Methods: A prospective, interventional study. PiCCO parameters were measured on 40 patients with septic shock at T0, T1, T3, T12, T24, T48.

Results: The mean time to vasopressor discontinuation was 27,8 ± 20,9 hours. The in-hospital mortality rate was 32,5% and the 30 - day mortality rate was 35%. Risk factors for death included cirrhosis (p = 0,04), diabetes mellitus (p = 0,03), lactate at T0 ≥ 4 mmol/L (p = 0,03), multiple organ dysfunction ≥ 3 (p = 0,03), APACHE II score at T48 ≥ 23 (p =0,02), mechanical ventilation (p < 0,01), CI at T0 < 3 L/min/m² (p = 0,01), SVRI at T0 < 1200 DS/cm5/m² (p < 0,01), PVPI at T12 ≥ 3 (p = 0,04), and EVLWI at T0, T1, T3, T12, T24 ≥ 10 mL/kg (p < 0,05).

Conclusion: Time to vasopressor discontinuation was shorted, and mortality rate was reduced when resuscitating early with PiCCO system monitoring in patients with septic shock. Parameters on the PiCCO system help predict the risk of death. Keywords: PiCCO, Septic shock.

Published: March 2024

Neste artigo, procuramos entender melhor a relação entre a alocação ótima dos investimentos em educação pelos estados brasileiros e o crescimento econômico desses estados, inspirados pelo modelo de Aghion et al. (2005). Os resultados mostram que, embora os gastos educacionais não tenham impacto significativo sobre o crescimento, a qualidade do ensino médio tem impacto positivo para os estados brasileiros mais próximos à fronteira de renda. Nossas estimativas indicam que a qualidade do ensino médio se torna mais importante do que o a do ensino fundamental para os estados com renda per capita maior ou igual a 60% da fronteira.

Published: March 2024

Neste trabalho, utilizamos a dinâmica observada da taxa de inflação e da estrutura a termo das expectativas de inflação futura (relativas aos horizontes prospectivos de 12, 24, 36 e 48 meses) para estimar a trajetória da tendência de longo prazo da inflação. Essa tendência é tratada como uma variável latente em um modelo em espaço de estado, sendo estimada utilizando o filtro de Kalman. Comparando os seus valores com a meta de inflação perseguida pelo Banco Central do Brasil (BCB), consegue-se avaliar a ancoragem das expectativas e a credibilidade das autoridades monetárias. Observamos movimentos acentuados da credibilidade entre novembro de 2001 e setembro de 2019, com uma deterioração contínua iniciada em meados de 2007 e interrompida em 2016.

Investigating the effects of discipline and first-language backgrounds on ITAs’ instructional discourse patterns
Authors: Chang Heesun
Published: March 2024

Using a multidimensional analysis (MDA), this study aimed to increase the understanding of international teaching assistants’ (ITAs’) instructional language use by analyzing co-occurring linguistic features during their mock-teaching presentations in ITA assessment. With this purpose, the study examined the effects of ITAs’ proficiency levels, disciplines, and first-language backgrounds on their discourse patterns. The data comprised a corpus of 165 prospective ITAs’ mock-teaching presentations in ITA assessment. Based on the two dimensions of the twenty-six linguistic features found prevalent in university classroom talk (Csomay, 2005), an additive MDA was performed. Overall, the mock-teaching presentations of more proficient ITAs involved more contextual, directive, and personalized framing discourse features, with interaction effects for the ITAs’ disciplines and first-language backgrounds. The study discusses the implications for ITA training and assessment and directions for future studies.

We study a new population of extremely red objects (EROs) recently discovered by the James Webb Space Telescope (JWST) based on their NIRCam colors F277W − F444W > 1.5 mag. We find 37 EROs in the Cosmic Evolution Early Release Science Survey (CEERS) field with F444W < 28 mag and photometric redshifts between 5 < z < 7, with median

. Surprisingly, despite their red long-wavelength colors, these EROs have blue short-wavelength colors (F150W − F200W ∼ 0 mag) indicative of bimodal spectral energy distributions (SEDs) with a red, steep slope in the rest-frame optical, and a blue, flat slope in the rest-frame UV. Moreover, all these EROs are unresolved, point-like sources in all NIRCam bands. We analyze the SEDs of eight of them with MIRI and NIRSpec observations using stellar population models and active galactic nucleus (AGN) templates. We find that dusty galaxies or obscured AGNs provide similarly good SED fits but different stellar properties: massive and dusty,

Additional photometry at mid-infrared wavelengths will reveal the true nature of the red continuum emission in these EROs and will place this puzzling population in the right context of galaxy evolution.
Silicate Extinction Profile Based on the Stellar Spectrum by Spitzer/IRS
Authors: Shao 邵 Zhenzhen 珍珍 , Jiang 姜 Biwei 碧沩
Published: March 2024

The 9.7 and 18 μm interstellar spectral features, arising from the Si–O stretching and O–Si–O bending modes of amorphous silicate dust, are the strongest extinction features in the infrared. Here we use the “pair method” to determine the silicate extinction profile by comparing the Spitzer/IRS spectra of 49 target stars with obvious extinction with those of unreddened stars of the same spectral type. The 9.7 μm extinction profile is determined from all the 49 stars and the 18 μm profile is determined from six stars. It is found that the profile has a peak wavelength at ∼9.2–9.8 and ∼18–22 μm, respectively. The peak wavelength of the 9.7 μm feature seems to become shorter for stars of late spectral types; meanwhile the FWHM seems irrelevant to the spectral type, which may be related to circumstellar silicate emission. The silicate optical depth at 9.7 μm, Δτ
9.7, mostly increases with the color excess in J − K

, this proportionality changes. The correlation coefficient between the peak wavelength and the FWHM of the 9.7 μm feature is 0.4, which indicates a positive correlation considering the uncertainties of the parameters. The method is compared with replacing the reference star by an atmospheric model spectral energy distribution and no significant difference is observed.

We report observations of the ground state transitions of 12CO, 13CO, C18O, HCN, and HCO+ at 88–115 GHz in the inner region of the nearby galaxy IC 342. These data were obtained with the 16 pixel spectroscopic focal plane array Argus on the 100 m Robert C. Byrd Green Bank Telescope (GBT) at 6″–9″ resolution. In the nuclear bar region, the intensity distributions of 12CO(1–0) and 13CO(1–0) emission trace moderate densities, and differ from the dense gas distributions sampled in C18O(1–0), HCN(1–0), and HCO+(1–0). We observe a constant HCN(1–0)-to-HCO+(1–0) ratio of 1.2 ± 0.1 across the whole ∼1 kpc bar. This indicates that the HCN(1–0) and HCO+(1–0) lines have intermediate optical depth, and that the corresponding

of the gas producing the emission is of order 104.5−6 cm−3. We show that HCO+(1–0) is thermalized and HCN(1–0) is close to thermalization. The very tight correlation between the HCN(1–0) and HCO+(1–0) intensities across the 1 kpc bar suggests that this ratio is more sensitive to the relative abundance of the two species than to the gas density. We confirm an angular offset (∼10″) between the spatial distribution of molecular gas and the star formation sites. Finally, we find a breakdown of the L

correlation at high spatial resolution due to the effect of incomplete sampling of star-forming regions by HCN emission in IC 342. The scatter of the L

relation decreases as the spatial scale increases from 10″ to 30″ (170–510 pc), and is comparable to the scatter of the global relation at a scale of 340 pc.
Avec et contre le droit, tout contre. Stratégies para-politiques de transgressions du droit en milieu populaire pour défendre ses « petites libertés »
Authors: Darras Éric
Published: March 2024

Certains autodidactes s’acharnent à bien maîtriser le droit pour mieux s’en servir, pour le manipuler ou le contourner et il s’en trouve parmi les membres des classes populaires. L’art populaire de la personnalisation des véhicules, le tuning, constitue per se un jeu avec le Code de la route. L’observation ethnographique des teams et meetings de tuning révèle des malentendus interprétatifs entre le « droit des livres » et le « droit en acte » qui s’avèrent parfois productifs, parfois contreproductifs. Ces rares autodidactes qui s’intéressent au droit pour mieux le transgresser renforcent ainsi par une gymnastique politique quotidienne leurs dispositions critiques comme ils contribuent sans doute paradoxalement, au fond, à légitimer la domination légale-rationnelle ; ils participent du processus éliasien de « civilisation » ou mieux de « disciplinarisation » des habitus populaires.
Les droits de l’enfant à l’épreuve de normativités plurielles
Authors: Capelier Flore
Published: March 2024

Croiser les disciplines et les regards sur l’enfant permet de déconstruire une vision universaliste du droit pour s’intéresser à la singularité psychique, culturelle et sociale de chaque enfant. Quelles sont les normes qui s’appliquent aujourd’hui aux enfants et comment ont-elles évolué sur un plan historique, juridique, institutionnel, mais aussi, au quotidien, dans les liens qui unissent l’enfant aux adultes qui l’entourent ? La présente contribution propose une mise en perspective des droits de l’enfant face à des normativités plurielles et cherche à mieux comprendre l’écart qui existe, entre le droit en vigueur et les actions menées au quotidien auprès des enfants et des familles.

Cet article traite de l’ Extreme Programming (XP), une approche assez nouvelle du génie logiciel « orienté utilisateur », qui rencontre un succès croissant dans son domaine. L’ Extreme Programming propose de centrer le développement collaboratif de logiciels sur les pratiques de programmation. Cette proposition le distingue nettement d’autres méthodologies de génie logiciel plus dépendantes de leurs instruments, plus formalisées et gérées d’une manière plus centralisée. Cet article décrit les interactions d’une équipe d’ Extreme Programming œuvrant au développement d’un progiciel de gestion de connaissances organisationnelles. En nous appuyant sur des techniques ethnographiques, nous y analyserons le développement de ce mode particulier de production de logiciels dans un lieu donné et l’hybridation singulière de documents, de conversations, d’outils logiciels et d’un agencement des bureaux qu’il y a provoqué. Nous examinerons quelques éléments parmi la vaste gamme de dispositifs, d’appareils, de techniques et de discours qui s’assemblent au cours de la production d’un système logiciel complexe contemporain. Nous soutiendrons que l’accent que met l’XP sur la programmation en tant qu’activité centrale et métaphore directrice ne peut être compris qu’à l’aune de sa concurrence avec des approches de génie logiciel expressément formelles et en lumière des cadres organisationnels du développement de logiciels. Comme nous le verrons, l’XP prend son essor en ré-incarnant les habitudes des métiers de la programmation en une pratique collective.
Une direction des systèmes d’information en « transformation agile »
Authors: Ughetto Pascal
Published: March 2024

Les principes et méthodes agiles ont connu un grand succès qui a conduit des directions d’entreprises, à partir des années 2010, à vouloir les intégrer dans des programmes de transformation des modes de fonctionnement internes. On parle parfois de transformation agile. La nouvelle mode managériale a pour particularité de tenter d’intégrer dans une régulation de contrôle ce qui se présente d’abord comme une régulation professionnelle profondément inscrite dans le métier de développeur. Les cadres de gestion de projet, en matière de développement de logiciels, sont le cœur du débat ouvert par le manifeste agile mais ce sont des cadres partagés avec d’autres acteurs de ces projets, comme les directions financières. L’article étudie le cas d’une direction des systèmes d’information qui réussit d’autant mieux son appropriation des méthodes agiles qu’elle s’y est engagée en toute autonomie. Plus encore, l’activité même conduit les individus à pratiquer une veille constante, à explorer et à se constituer par eux-mêmes une doctrine, des méthodes et des outils de gestion de projet légitimes. Les limites sont moins le maintien de logiques hiérarchiques que la contradiction avec une gouvernance des projets en termes de contrôle de gestion qui demeure profondément classique et témoigne de la difficulté durable des informaticiens à transformer les normes organisationnelles de gestion des projets.
Evolving blocks by segmentation for neural architecture search

Published: March 2024

Convolutional neural networks (CNNs) play a prominent role in solving problems in various domains such as pattern recognition, image tasks, and natural language processing. In recent years, neural architecture search (NAS), which is the automatic design of neural network architectures as an optimization algorithm, has become a popular method to design CNN architectures against some requirements associated with the network function. However, many NAS algorithms are characterised by a complex search space which can negatively affect the efficiency of the search process. In other words, the representation of the neural network architecture and thus the encoding of the resulting search space plays a fundamental role in the designed CNN performance. In this paper, to make the search process more effective, we propose a novel compact representation of the search space by identifying network blocks as elementary units. The study in this paper focuses on a popular CNN called DenseNet. To perform the NAS, we use an ad-hoc implementation of the particle swarm optimization indicated as PSO-CNN. In addition, to reduce size of the final model, we propose a segmentation method to cut the blocks. We also transfer the final model to different datasets, thus demonstrating that our proposed algorithm has good transferable performance. The proposed PSO-CNN is compared with 11 state-of-the-art algorithms on CIFAR10 and CIFAR100. Numerical results show the competitiveness of our proposed algorithm in the aspect of accuracy and the number of parameters.
Event-triggered fixed/preassigned time stabilization of state-dependent switching neural networks with mixed time delays
Authors: Gao Jiashu , Han Jing , Zhang Guodong
Published: March 2024

This study employed an event-triggered control (ETC) strategy to investigate the problems of fixed-time stabilization (FTS) and preassigned-time stabilization (PTS) for state-dependent switching neural networks (SDSNNs) that involved mixed time delays. To enhance the network's generalization capability and accelerate convergence stabilization, a more intricate weight-switching mechanism was introduced, then to mitigate transmission energy consumption, this paper proposed a tailored event-triggering rule that triggered the ETC solely at predetermined time points. This rule ensured the stability of the system while effectively reducing energy consumption. Using the Lyapunov stability theory and various inequality techniques, this paper presented new results for FTS and PTS of SDSNNs. The validity of these findings was supported by conducting data simulations in two illustrative examples.
Analysis of a COVID-19 model with media coverage and limited resources
Authors: Chen Tao , Li Zhiming , Zhang Ge
Published: March 2024

The novel coronavirus disease (COVID-19) pandemic has profoundly impacted the global economy and human health. The paper mainly proposed an improved susceptible-exposed-infected-recovered (SEIR) epidemic model with media coverage and limited medical resources to investigate the spread of COVID-19. We proved the positivity and boundedness of the solution. The existence and local asymptotically stability of equilibria were studied and a sufficient criterion was established for backward bifurcation. Further, we applied the proposed model to study the trend of COVID-19 in Shanghai, China, from March to April 2022. The results showed sensitivity analysis, bifurcation, and the effects of critical parameters in the COVID-19 model.
