Abstract To resolve the problems of adding unsprung mass and worsening ride comfort of hub motor drive electric vehicles, a new drive system with hub motor as dynamic absorber is studied and proposed. The mathematical models of the new hub motor drive system and the centralized motor drive system are established, and their ride comfort is compared and analyzed. The impact of dynamic absorber parameters on ride comfort of the new hub motor drive system is analyzed, and the parameter sensitivity is calculated. The results show that the body acceleration, suspension dynamic deflection, wheel dynamic load of the new hub motor drive system are better than those of the centralized motor drive system, and the dynamic absorber parameters have a great effect on the electric vehicle performance.

The local water supply corporation in Indonesia only uses analog water meter so that the monitoring of water usage information was conducted by officers manually. Officers must physically monitor the value in the customer's water meter that can lead to unreliable reading and ineffectiveness of process. Smart meter is one of the smart city metrics which could overcome this problem. This research uses the flow sensor to design and incorporate automated water meters. The measured value is then passed via the 433 MHz LoRa, a low-power wide-area network protocol, to the local hub, then forwarded to the server via the internet based cellular network. Results show that our proposed system's accuracy hit 97.31% at an ideal distance of 200 meters from customer to the local hub. The customer's water usage could be tracked in real time with our proposed system. Furthermore, the original water meter need not to be replaced which may minimize capital costs for this system.

Full textAbstract:
A centralized carrier collaboration multihub location problem (CCCMLP) for the small to medium-sized less-than-truckload industry is addressed. In the CCCMLP, a central entity (e.g., a third-party logistics firm) seeks a set of collaborative consolidation transshipment hubs to establish a hybrid collaborative hub-and-spoke system that minimizes the total collaborative costs for the set of collaborating carriers. Previous studies focused on addressing the exchange of capacity without considering the location of transfer hubs and the routes that connect them. A carrier has the option either to collaborate or to ship its demand directly without collaborating. The decision depends on the expected profit margin over shipping directly while following a revenue-generating, rate-setting behavior. The CCCMLP was formulated as a variant of the P-hub location problem, which is NP-hard and solved with Lagrangian relaxation. Numerical experiments were conducted to gain insight into the performance of the CCCMLP formulation under various network sizes and numbers of hubs. The results indicate that larger expected profit margins from collaborative carriers applying revenue-generating behavior would increase the likelihood of collaboration by carriers. As the network size increases, the effect of hybrid hub location costs drops.

193 Background: Cervical cancer is the most prevalent gynecologic cancer worldwide, but is third in the U.S. due to pap smear screening. However, American Society for Colposcopy and Cervical Pathology (ASCCP) guidelines are complex and frequently changed, resulting in guideline adherence as low as 33-44%. We describe a centralized pap smear tracking system (“pap hub”) and report preliminary results. Methods: On 1/1/13 we implemented the pap hub, routing all screening pap smear results to a dedicated OB/Gyn nursing staff with a new Epic workbench. Epic Health Maintenance Modifier updated to recommend pap smears for women age 21-65 years (not younger or older per guidelines). Screening Pap/HPV results auto routed to Pap Pool Epic inbasket (not to individual providers). Centralized nurse reviews results alongside past pap results on Pathology flowsheet in Epic If normal Normal history -> appropriate follow-up interval per screening guidelines If abnormal history -> repeat pap as determined by previous history and treatment If abnormal -> manage per ASCCP guidelines Document plan in Epic Result Note Update Epic problems list If Normal: document “Pap Hub Normal History” If Abnormal: document “Pap Hub Abnormal History” with specifics in Overview History Communicate results/plan to the patient. Update Health Maintenance Modifier with next step. Review abnormal results to ensure proper follow-up, with reminders as indicated. Results: Guideline recommendations against pap smears for patients <21 years and >65 years have not changed since 2009. Comparison of first-quarter data for 2010 (pre-Pap Hub) to 2013 (post-Pap Hub) have shown a 63.86% reduction in pap smears in women <21 years. Pap smears in women >65 years has always been low, but has decreased slightly from 2.4% of all pap smears in 2010 to 1.5% of all pap smears in 2013. The 2012 ASCCP guidelines have changed recommended pap smear frequency and abnormal pap smear follow-up, and compliance with these new recommendations is being collected. Conclusions: Pap smear screening has decreased the incidence of invasive cervical cancer in the United States. The Pap Hub, a centralized pap smear tracking system, improves compliance with pap smear screening guidelines.

It is difficult to control and coordinate inventory of assembly manufacturing supply chain because there are multi-suppliers in control system. In order to integrate different suppliers and send parts packages to production line directly, Supply-Hub is used in practice. Queuing theory and basic inventory strategy are applied to model inventory control of assembly manufacturing supply chain with Supply-Hub mode. And optimization solution for decentralized decision and centralized decision were derived separately. Then coordination inventory strategy is obtained by comparing decentralized decision and centralized decision. Backorder and holding cost subsidy contracts are used for coordination that incites suppliers to set basic inventories in favor of whole supply chain operation cost reduction. And numerical examples of three suppliers and one manufacturer are given to illustrate the effectiveness of the coordination strategy.

This study developed a Learning Materials Repository Hub (LMRH) to digitize educational resources for the K-12 education system, addressing the need for centralized, high-quality, and accessible learning materials. Using a developmental research approach, Graduate School students created Digitized Learning Materials (DLMs) aligned with the Most Essential Learning Competencies (MELCs) and the Alternative Delivery Mode Learning Resource (ADMLR) standards of the Department of Education (DepEd). These materials were reviewed by subject-matter experts and integrated into the LMRH, which was designed as a centralized platform for organizing and sharing digital learning content. The study employed expert evaluations and teacher assessments to determine the content quality, educational effectiveness, technical usability, and overall acceptability of the LMRH. The Technology Acceptance Model (TAM) was used to measure perceived usefulness, ease of use, attitude toward using, and intention to use, while the System Usability Scale (SUS) evaluated its usability. Findings revealed that the DLMs received high ratings for quality, and the LMRH was deemed effective in supporting both synchronous and asynchronous learning. Teachers strongly agreed on its usefulness and ease of integration into teaching. The results suggest that digital learning repositories can significantly enhance teaching and learning experiences, providing a flexible and efficient platform for educators. The study highlights the importance of digitized educational resources and encourages further investment in educational technology to improve curriculum implementation and educational delivery in K-12 education.

To resolve the difficulties in deployment of the classic security solution S-BGP (Secure Border Gateway Protocol), the Translator Trust Model (TTM) for a new solution SE-BGP (Security Enhanced BGP) was proposed to transform the centralized deployment mode of S-BGP to distributed mode. However, the trust (attestations of routing information) translation of TTM only depends on a single hub node and this results in severe threats for the inter-domain routing system. To overcome the deficiencies of TTM, in this paper we improve TTM to Distributed TTM (DTTM) by expanding the single hub node to a set of selected multiple hub nodes; in our DTTM, the task of attestations is distributed over multiple hub nodes instead of on a single hub node. In order to make the hub nodes respond to the case of single node failures, we design a restoration mechanism to recover the network based on the neighbour-ring structure. Besides, we develop Cooperative Secure BGP (CSBGP) to realize DTTM in BGP. In comparison with SE-BGP, our experimental results show that CS-BGP achieves an improved scalability, reduced convergence time and enhanced security.

Abstract: The demand for water supply has increased unpredictably worldwide over the past few decades, posing a major challenge. To overcome this challenge, an IoT-based water monitoring and control approach is presented, which supports realtime internet-based data collection. The device comprises a computer system (central hub), an IoT module, a switching unit, and a Zigbee module. The Internet of Things is a network of devices embedded with electronics, software, and sensors that enable them to exchange and analyze data. The centralized hub distributes water individually based on the needs of each household, assisted by IoT integration of communications, control, and information processing across the systems used. This allows water quantity and quality to be sensed at each structure in a particular sector, providing remote access control of the water supply. The centralized hub monitors and shares water among localized tanks or resupplies water from its reservoir according to a rank’s deficit or excess water level. Personal area networks are created in this scenario where a wireless connection is required across the system. UV treatment is deployed to improve the quality of water distributed to every household, and fluoride content level along with hardness checking is done using respective test meters. Overall, the IoT-based water monitoring and control approach design presents an innovative solution to the increasing demand for water supply, enabling efficient distribution and ensuring water quality.

The US COVID-19 Forecast Hub, a repository of COVID-19 forecasts from over 50 independent research groups, is used by the Centers for Disease Control and Prevention (CDC) for their official COVID-19 communications. As such, the Forecast Hub is a critical centralized resource to promote transparent decision making. While the Forecast Hub has provided valuable predictions focused on accuracy, there is an opportunity to evaluate model performance across social determinants such as race and urbanization level that have been known to play a role in the COVID-19 pandemic. In this paper, we carry out a comprehensive fairness analysis of the Forecast Hub model predictions and we show statistically significant diverse predictive performance across social determinants, with minority racial and ethnic groups as well as less urbanized areas often associated with higher prediction errors. We hope this work will encourage COVID-19 modelers and the CDC to report fairness metrics together with accuracy, and to reflect on the potential harms of the models on specific social groups and contexts.

The system aims to collect data on user behaviour and preferences on various social media platforms such as Instagram and Twitter. The aim is to determine influential users and increase engagement. In contrast to conventional methods that focus on a single platform at a time, the Multiple Platform Hub and Authority Topic (MPHAT) model provides an overall view of users by examining their connections, interests, and favourite networks. The MPHAT model seeks to bring less prominent users into the limelight by overcoming limitations within recommendation systems that benefit popular users. It makes online traffic estimates based on platform-specific posts and user preferences. Furthermore, the MPHAT model excels over conventional techniques such as LDA in topic understanding, influence prediction, and user behaviour prediction.

Full textAbstract:
Abstract Objective While depression and anxiety are common mental health issues, only a small segment of the population has access to standard one-on-one treatment. The use of smartphone apps can fill this gap. An app recommender system may help improve user engagement of these apps and eventually symptoms. Methods IntelliCare was a suite of apps for depression and anxiety, with a Hub app that provided app recommendations aiming to increase user engagement. This study captured the records of 8057 users of 12 apps. We measured overall engagement and app-specific usage longitudinally by the number of weekly app sessions (“loyalty”) and the number of days with app usage (“regularity”) over 16 weeks. Hub and non-Hub users were compared using zero-inflated Poisson regression for loyalty, linear regression for regularity, and Cox regression for engagement duration. Adjusted analyses were performed in 4561 users for whom we had baseline characteristics. Impact of Hub recommendations was assessed using the same approach. Results When compared to non-Hub users in adjusted analyses, Hub users had a lower risk of discontinuing IntelliCare (hazard ratio = 0.67, 95% CI, 0.62-0.71), higher loyalty (2- to 5-fold), and higher regularity (0.1–0.4 day/week greater). Among Hub users, Hub recommendations increased app-specific loyalty and regularity in all 12 apps. Discussion/Conclusion Centralized app recommendations increase overall user engagement of the apps, as well as app-specific usage. Further studies relating app usage to symptoms can validate that such a recommender improves clinical benefits and does so at scale.

Software-Defined Networking (SDN) is a networking design approach, which separates the data plane from the control plane, providing the network with certain benefits due to centralized programmatic control. SDN provides a centralized view and enables management of the entire network. It offers flexibility in configuration, reduces time to deploy, provides automation and facilitates building a network without requiring the knowledge of any vendor-specific software/hardware. SDN offers the datacenter network benefits such as improving traffic and security management as well as providing a scalable infrastructure. Load balancing enhances the performance of the network by distributing traffic among servers and therefore preventing congestion and server underutilization. This paper aims to explore SDN and test its implementation and demonstrate how to implement its concepts within a datacenter network. The experiment considers the datacenter network implemented in Sudan University of Science and Technology as a case study. The edited network topology is made up of a Demilitarize Zone (DMZ) having three servers, a Local Area Network (LAN) and a main switch. The Hub, Switch and Load balancer scenarios are implemented using Mininet emulator. In addition, the three scenarios are tested using external devices and analyzed using Wireshark. Moreover, the connectivity of HTTP and FTP is verified.

Full textAbstract:
Background: Pancreaticoduodenectomy (PD) is associated with major morbidity and mortality especially in low volume centers. A centralized model is not suitable for Indonesia, due to its geographical characteristics and the underlying structure of its health funding. As an alternative, an outreach program was developed and delivered by a dedicated hepatopancreatobiliary (HPB) team. The aim of this study was to describe the outcomes of such approach. Methods: A retrospective study of all patients undergoing Pancreaticoduodenectomy or total pancreatectomy by a single HPB team was performed. A “hub and spoke” model /decentralization strategy was used to deliver the care between a tertiary center and eight peripheral centers. Patient demographics, system measures, and outcomes were collected. Results: A total of 213 patients were identified as undergoing a resection within the period of 1993–2017. A total of 47 resections (22%) were performed at a peripheral center. The median age was 51 years and 91(46%) of patients had ampullary carcinoma. The perioperative mortality was 17% but improved over time. Only 19/198 (9.5%) patients with the malignant disease received adjuvant therapy. The median (95%CI) survival for patients with pancreatic and ampullary cancer was 12 (9-15) and 24 (14-34) months respectively. Conclusions: A hub and spoke model as a decentralization strategy for managing patients with peri-ampullary tumors can lead to an improvement in access and outcomes. However further work is required if they are to achieve outcomes achieved by international high-volume centers within centralization programs.

Introduction. Efficient freight transport and management in large transportation hubs is crucial to world trade. Existing freight management systems fail to ensure traceability, transparency, information security and consistency of data stored and exchanged during the various operational processes. As a result, this has a negative impact on the performance of transport hubs.Materials and methods. The use of digital information and communication technology (ICT) applications in the transport industry can lead to highly automated processes and more cost-effective solutions. Freight transport requires the use of real-time data exchange between different stakeholders involved in the process. Traditional ICTbased logistics systems use a centralised architecture to host and process data and services. However, centralized logistics systems cannot ensure secure access to real-time data, operational visibility and trust between participating organisations.Results. Automation of various transport hub functions using the Internet of Things (IoT) and cloud computing can adequately improve the performance of transport hub operations. These operations include automation of vehicle interface, container yards, intra-port logistics and terminal receiving point.Discussion and Conclusions. In this paper, we have explored opportunities for process improvement by integrating information exchange between different actors using end-to-end technologies in transport hubs, in particular the concept of blockchain, to optimise operations in international trade by integrating and sharing information between actors in the transport process.

PurposeInnovative startups have begun a trend using laser sintering (LS) technology patents expiration, namely, by introducing LS additive manufacturing (AM) machines that can overcome utilization barriers, such as the costliness of machines and productivity limitation. The recent rise of this trend has led the authors to investigate this new class of machines in novel settings, including hub configuration. There are various supply chain configurations to supply spare parts in industrial operations. This paper aims to explore the promise of a production configuration that combines the benefits of centralized production with the flexibility of local manufacturing without the huge costs related to it.Design/methodology/approachThis study quantitatively examines the feasibility of different AM-enabled spare parts supply chain configurations. Using cost data extracted from a case study, three scenarios per AM machine technology are modeled and compared.FindingsResults suggest that hub production configuration depending on the utilized AM machines can provide economic efficiency and effectiveness to reduce equipment downtime. While previous studies have suggested the need for AM machines with efficiency for single part production for a distributed supply chain, the findings in this research illustrate the positive relationship between multi-part production capability and the feasibility of a hub manufacturing configuration establishment.Originality/valueThis study explores the promise of a production configuration that combines the benefits of centralized production with the flexibility of local manufacturing without the huge costs related to it. Although the existing body of knowledge contains research on production decentralization, research on various levels of decentralization is lacking. Using a real-world case study, this study aims to compare the feasibility of different levels of decentralization for AM-enabled spare parts supply chains.

OBJECTIVES/GOALS: Mayo Clinic implemented a CRC Placement Hub to improve hiring experiences for candidates and hiring managers. Candidates apply to a centralized posting. A Placement Coordinator handles administrative and screening responsibilities, allowing hiring managers to focus on selecting best candidates. METHODS/STUDY POPULATION: The CRC Placement Hub was implemented in phases. Initially, first and second interviews were conducted using Zoom and hiring manager utilization of the Hub was voluntary. Positive candidate and hiring manager feedback shifted Hub utilization to the standard practice and hiring managers must request an exception to post separately for unique candidate requirements. The third phase progressed to utilizing the HireVue hiring platform. Qualified candidates are invited to complete an on-Demand interview at their convenience, which hiring managers utilize to select candidates to continue through the interview process. HireVue utilization has decreased time to fill metrics for CRC candidates. RESULTS/ANTICIPATED RESULTS: The intentions for the CRC Placement Hub are to offer a positive hiring experience for candidates and reduce administrative burden for the hiring managers, while maintaining autonomy of hiring decisions. Additional purposes for the Hub are to increase the candidate pool by developing recruitment pipelines and decrease overall timeline to fill an open position. Qualitative and quantitative metrics were established to monitor performance. Metrics depict positive experiences for candidates and hiring managers, and decreased timelines to fill open positions. Candidate pools continue to increase as the Hub Placement Coordinator holds off-campus and online recruitment events. DISCUSSION/SIGNIFICANCE: The CRC Placement Hub provides candidates a positive experience, allowing them to apply to one posting but considered for all open positions. The Hub decreases administrative burden for hiring managers, allowing them to focus on critical aspects of candidate selection and managing clinical research.

The real estate industry is undergoing a rapid transformation as digital tools and technologies emerge to address long-standing inefficiencies. However, despite advancements, real estate transactions remain complex, fragmented, and time-consuming. Traditional processes often require users to access multiple platforms, rely on multiple intermediaries, and undergo lengthy paperwork, all of which contribute to delays, high costs, and user frustration. This project aims to tackle these issues through the development of an integrated online platform, or “Real Estate Hub,” designed to streamline the entire property transaction process, including buying, selling, and renting properties. The Real Estate Hub offers a centralized, end-to-end solution to overcome the challenges posed by a fragmented market. By consolidating all essential elements of a real estate transaction property listings, legal and financial services, documentation, and secure payments the platform provides users with a one-stop solution for all property-related needs. A major feature of the platform is its advanced search functionality, powered by AI algorithms, which enables users to filter and personalize their property searches according to specific criteria, such as location, price range, and amenities. This AI-driven approach not only simplifies the search experience but also enhances it by offering tailored recommendations based on users' preferences. Transparency and trust are critical in real estate, yet users frequently encounter issues such as hidden fees, unverified listings, and complex legal jargon. The Real Estate Hub addresses these pain points by providing comprehensive, verified information on all properties listed on the platform, including clear transaction fees, detailed property histories, and access to relevant documentation. Additionally, the platform integrates secure payment gateways and digital document management tools, enabling users to completefinancial transactions and paperwork safely and efficiently.

Pharmaceutical serialization is a regulatory compliance that assures a unique identifier assigned to every unit of prescribed medicine. This unique identifier is used for product tracking and authentication in the supply chain. Initially, in 2018, the Drug Supply Chain Security Act (DSCSA) implemented pharmaceutical drug serialization regulations to mitigate the risk of counterfeit medicine entering the US market. Under this regulation, the pharmaceutical drug manufacturer is required to print a 2D data matrix barcode encoded with unique identification on each drug unit. Basically, printing a unique identification code on each prescribed drug for authenticity and traceability is not sufficient to eliminate the risk of drug counterfeiting. Subsequently, criminals and drug counterfeiters can still supply illicit or stolen drugs into the supply chain through an illegal source or online trade by imitating the same information in multiple units. After this regulation's enforcement, we observed that the US market lacks a mechanism to authenticate individual drug units with a centralized, secure repository before dispensing them to patients. Since the COVID-19 pandemic, drug counterfeiters and criminals have produced large quantities of contaminated drugs, which they then distribute through their illicit networks and underground social media platforms. Furthermore, COVID-19 supply chain disruptions, non-business resilience, and the fear of ransomware have all contributed to a rise in the mass fabrication of counterfeit medications. Ultimately, the United States needs a centralized cloud-based database hub where all authorized trading partners should be connected for medicine authentication. In this process, the manufacturer must update the product's unique identifier in the centrally connected hub database before supplying drugs to the market. Further, the dispenser, pharmacy, or hospital should authenticate the unique identifier of the product using the same database before dispensing it to patients. Finally, this process will ensure that patients are getting authenticated medicine and will mitigate the risk of dispensing counterfeit or illegal drugs.

Abstract The paper debates the comparison between centralized cyber-physical systems and distributed cyber-physical systems (CPS). Centralized CPS implies a system where a single player standardizes data format and protocol together with core services. Distributed CPS implies a system where varieties of digitalization systems by multiple vendors are interconnected to adapt to specific local contexts. Then the paper identifies that distributed CPS has practical advantages over centralized CPS. However, distributed CPS has potential disadvantages that threaten interconnectivity among digitalization systems by multiple vendors. The paper illustrates how such fragmentation could be avoided; it presents how interoperable linkage among multiple systems is realized. IoT-Hub, a sort of data conversion system, is an enabler of interoperability. The paper illustrates the framework of distributed CPS. That comprises several layers that could be managed autonomously by independent players regardless of activities in other layers. The paper exemplifies local-based frugal innovation by such distributed CPS. One example is IoT-based proactive energy demand control system. The system is composed of sensing systems, component systems and application software. The distributed CSP that deploys IoT-Hub enables adaptable coordination of building elements and digitalized systems respecting local specific contexts. In such a way, distributed CPS provides a comfortable indoor climate with optimized energy use. The other example is IoT-based inventory system for building materials. The system is composed of manufacturing process monitoring systems and logistics monitoring systems. The integrated system could provide reportable and verifiable inventory data of building materials. The system can facilitate responsible use of building materials by providing inventory data that is a piece of essential information for environmental declaration. Exemplified cases suggest how distributed CPS strategy has the potential to encourage a broad range of entrepreneurs to commit to frugal innovation toward a sustainable built environment.

Network analysis was used to examine the properties of the B2B networks. A factor of innovation in information and communications technology (ICT) and logistics technology was introduced into an agent-based model to demonstrate changes occurring in the related structures of B2B networks. The agent-based model was designed and tested based on qualitative information on Japanese textile and apparel industries. Consequently, network analysis revealed power-law properties and the structures of centralized hub companies. Moreover, in the simulation experiments, the centralizations of the networks generated by the agent-based model due to innovation in ICT and logistics technology were illustrated. Therefore, one of the predicted cases regarding changes that occur in the B2B networks was explained as centralizations to hub companies.

Full textAbstract:
Medium access control (MAC) protocols play a vital role in making effective use of a multiple access channel as it governs the achievable performance such as channel utilization and corresponding quality of service of wireless sensor networks (WSNs). In this paper, a virtual carrier sensing directional hub (VSDH) MAC protocol incorporating realistic directional antenna patterns is proposed for directional single hub centralized WSNs. While in most instances, MAC protocols assume idealized directional antenna patterns, the proposed VSDH-MAC protocol incorporates realistic directional antenna patterns to deliver enhanced link performance. We demonstrate that the use of directional antennas with a suitable MAC protocol can provide enhanced communication range and increased throughput with reduced energy consumption at each node, compared to the case when only omnidirectional antennas are used. For the scenarios considered in this study, results show that the average transmit power of the sensor nodes can be reduced by a factor of two, and at the same time offer significantly extended lifetime.

Full textAbstract:
Aviation hubs are pivotal intermediate nodes for connecting people around the world. However, there has been limited investigation on the competitive hub landscape in the China–Oceania market. Employing an updated Connectivity Utility Model, we examine the hub connections provided by hubs in mainland China, Hong Kong and Macau, other Asian countries and Oceania from quantity and quality dimensions between 1997 and 2019. The results indicate that the solid growth of mainland China and Oceania hubs suppress the development of Hong Kong and other Asian hubs. The major competitions of the mainland China and Oceanian hubs have shifted from competing with hubs outside their respective regions to competing with hubs within their regions, while the primary competitors of other Asian hubs have changed from competing with each other to competing with hubs outside their region. In the monopoly market, the Oceanian hubs have always enjoyed the greatest monopoly superiority. In the overlapping market, the dominance of Hong Kong and other Asian hubs in both the quantity and quality dimensions has been challenged by mainland China hubs. In a semiregulated operating environment shaped by China’s centralized government, the coordination between airlines, airports and governments is crucial for future hub construction.

This project presents a Smart Parking System tailored to address the unique parking challenges of organizations and restricted-access entities. It integrates Infrared (IR) sensors, Radio-Frequency Identification (RFID) tags, and Cloud connectivity. IR sensors monitor parking space occupancy in real-time, while RFID tags serve as secure physical credentials for authorized personnel, enhancing access control. The system incorporates a Blynk app for authorized users to access real-time parking data, check availability, and helps users make informed decisions about parking. This app acts as a centralized hub for efficient parking management, improving the overall parking experience. Architecturally, the system utilizes a centralized control unit controlling interactions between IR sensors, RFID authentication, and the Blynk cloud server. This approach allows only authorized users to access the parking lot, resulting in a scalable and adaptable solution prioritizing exclusivity, efficiency, convenience, and security in parking management for specialized environments.
