ОПТИМІЗАЦІЯ ПРОЦЕСІВ АВАРІЙНОГО ВІДНОВЛЕННЯ СЕРВІСІВ ІНФОРМАЦІЙНОЇ ІНФРАСТРУКТУРИ

The article describes the optimization of the process of disaster recovery of information infrastructure services by implementing the ability to restore service functionality without requiring a full recovery from backup storage. It outlines the criteria and parameters of the network that have a critical impact on recovery in the event of emergencies, allowing for the assessment of the solution's effectiveness in post-disaster recovery. A modification to the MTTR (Mean Time To Recovery) parameter is proposed for cases involving system element recovery from a backup or through service configuration restoration via infrastructure as code, with data necessary for service operation retrieved from backup storage, thereby accelerating the recovery process of a failed information infrastructure service. The article presents a scheme for infrastructure recovery organization by creating a backup location (Cold Site) for local infrastructure using dedicated cloud providers. The proposed solution utilizes Proxmox Backup Server capabilities for regular backups of critically important data center components. Following the development of a flowchart for the service recovery method from the Cold Site, research findings indicated that, for some services, reinstating configurations from code is more advantageous and speeds up the recovery process more than complete service restoration from backup storage.

Effect of aging level on the healing properties of an induction-heated ultra-thin wearing course and its mechanism

Electromagnetic induction heating can accelerate crack self-healing in asphalt concrete and extend its service life. In the maintenance project of existing pavements, induction heating and ultra-thin wearing course can be combined by paving functional induction heating wearing course. However, the ultra-thin wearing course is directly affected by the environment and loading, and undergoes aging in the service process. Thermo-oxidative aging is an irreversible and important mechanism that seriously affect the rheological and healing properties of asphalt. Therefore, the purpose of this work is to examine the impact of thermo-oxidative aging on the induction heating-healing of an ultra-thin wearing course mixture. Firstly, the AC-5 induction heated ultra-thin wearing course (IHUC) containing 1 % steel wool fiber by aggregate mass was prepared. Subsequently, the IHUC was aged to six different levels. Then, the induction heating and healing properties of the aged IHUC were evaluated. Simultaneously, the aged asphalt binder was extracted and its rheological characteristics and chemical alterations were studied. The outcomes showed that the heating rate of IHUC decreased, but the temperature gradient effect reduced at higher aging level. The optimal healing temperature of IHUC shifted to a higher temperature region and the healing rate decreased. Both heating cycles and thermo-oxidative aging reduce healing effectiveness, but the impact of heating cycles is less compared to aging. Rheology and chemical structure test results of extracted asphalt binder showed that the transformation of the molecular structure caused the fluidity and self-healing properties of asphalt were decreased. This ultimately decreased the healing rate of IHUC.

Hospital selection decision in emergency medical services: a simulation-based assessment of assignment criteria

ABSTRACT Emergency Medical Services play a fundamental societal role since they provide pre-hospital care to patients in critical and time-constrained conditions. In this context, the hospital selection decision is vital to respond in a timely, effective and efficient way. By means of simulation experiments, the present study compares the effects of different assignment logics against a set of performance dimensions. To this end, we develop a Discrete Event Simulation model that covers the entire Emergency Medical Service process, from the ambulance transportation to final departure of the patient from the Emergency Department. Results demonstrate that the use of effectiveness-related criteria (e.g. expected waiting time, resource saturation) significantly enhances the overall performance and, at the same time, guarantees higher quality of care. Thus, the study contributes in enhancing hospital selection decisions by supporting decision-makers through a comprehensive decisional model, distancing from prior researches that predominantly considered efficiency-driven criteria (i.e. proximity).

Study on the interference mechanism and fracture behavior of penetrating parallel double cracks

The existence of crack groups in structures is objective and inevitable during the process of manufacture and service. In this paper, the interactions between penetrating parallel double cracks are systematically investigated through finite element methods, experimental studies and theoretical analyses, where both the brittle dominant and ductile materials are taken as the research objects. The interactions between cracks are discussed through the interference factors C based on stress intensity factor K, which is related with the relative distance between crack tips. It is found that the fracture behaviors of multiple cracks are associated with all the interference factors at four crack tips. For the alignment double crack, shielding effects at all the crack tips cause the mutually exclusive crack propagations, and then strengthen the critical load of the specimen. For offset double cracks, the inner crack extension directions are attracted to each other, the outer crack extension directions are repelling each other, the critical loads depend on the degree of the attraction or the repelling effect. There exists a relationship between the comprehensive interference factor with all the crack tips included and the loading capacity. For the specimen with multiple surface cracks, the interference effects are also related with the relative distance between crack tips, through which it can be preliminary obtained that the regulations and the effect to the fracture behaviors are similar to those of penetrating cracked specimen, which will be discussed in detail in our next findings. The interference behaviors and critical loads of multiple cracks discussed above also provide an important basis on the coalescence and evaluation of multiple cracks.

Service quality improvement strategies of online car-hailing based on SPC-PCN method

Online car-hailing service is practicing the concept of sharing, bringing new energy and convenience to the transportation market. However, with its rapid development, service issues have become increasingly prominent, and improving service quality is the key to the sustainable growth of the online ride-hailing industry. Microblog, as a major online platform for gathering public views, have become one of the significant media for publishing and disseminating information nowadays, which also contains numerous views of online taxi users on online taxi services. Aiming at the deficiency of online car-hailing service under microblog public opinion, this paper integrates Service Profit Chain (SPC) and Process Chain Network (PCN) from the perspective of service management. Firstly, a crawler program is used to collect the Internet Word of Mouth data related to online taxi. Then, a BERT text classification model is constructed to roughly classify the data, and the accuracy of this model is tested to 94.54 %. Afterwards, layer segmentation is implemented based on SPC and CatBoost. Besides, a series of problems in the current online taxi service, such as poor attitude of drivers, unsafe driving, and inefficient communication with the customer service staff, have been identified by using sentiment analysis and frequent mining methods. Finally, PCN analysis is used to optimize the online taxi service, proposing strategies such as setting a reservation reminder function, building a dynamic feedback mechanism, and establishing a contact point for lost and found items. The new SPC-PCN online taxi service system constructed in this paper is vital for service quality optimization, and can also promote the sustainable growth of the online taxi market.

Stress-induced phase stability and optoelectronic property changes in cesium lead halide perovskites

Over the past decade, the certified power conversion efficiency of perovskite solar cells (PSCs) has increased to 26.1%. However, phase instability originating from lattice strains, has limited their commercialization. Strains will inevitably be generated during the PSC fabrication and service process due to the “soft lattice” nature of halide perovskites. In particular, flexible PSCs are subjected to not only mechanical tensile and compressive loads, but also suffer from thermal stresses. In this study, strain-induced changes in the phase stability and the corresponding optoelectronic properties of CsPbI3−xBrx (CsPbI3, CsPbBr3, and CsPbI2Br) systems under tensile and compressive stresses were investigated using first-principles calculations. The results showed that compressive stresses reduce the bandgap value and increase the light absorption coefficient; thus, the optoelectronic performance is improved, whereas the light absorption coefficient decreases regardless of how the bandgap changes under tensile stresses. Moreover, under the same stress, the tensile strain value was twice that of the compressive strain, and the critical value of the transition from the cubic to tetragonal phase was lower, indicating that phase stability was worse under tensile stresses. Therefore, during the fabrication of PSCs, the tensile stress state should be adjusted to the compressive stress state, which is favorable for enhancing PSCs photovoltaic performance and phase stability. The results not only provide direct evidence of tensile and compressive strains influencing the phase stability and optoelectronic property changes in halide perovskites, but also highlight lattice-strain tailoring for the composition design, process optimization, and interface engineering of efficient and stable PSCs.

Determinant of Eudaimonic Well Being: Case in Mimika Papua, Indonesia

Stakeholder participation and service experience are two important factors in increasing eudaimonic well-being. This research aims to examine the relationship between stakeholder participation, service experience, stakeholder empowerment, social support and eudaimonic well-being. This research used a survey method with 120 respondents consisting of village heads and community leaders spread across 18 districts in Mimika Regency, Central Papua Province, Indonesia. The research results show that stakeholder participation has a positive effect on service experience, stakeholder empowerment has a positive effect on service experience, service experience has a positive effect on eudaimonic well-being, and stakeholder participation does not support eudaimonic well-being. The results of this research also show that service experience mediation positively influences stakeholder participation towards eudaimonic well-being, while stakeholder empowerment and social support cannot moderate the relationship between stakeholder participation and service experience. This research also found that to ensure a pleasant service experience, Bappeda must design and manage service processes based on a good understanding of stakeholder needs and goals, in particular, the meaning of service in organizational life. In addition, to facilitate stakeholder interaction with staff services, Bappeda can also wisely empower stakeholders by adapting to the level of stakeholder participation.

Introduction: The aim is to assess the early impact of the current increased use of transurethral endoscopic procedures and emerging technologies on the management of urethral stricture disease (USD) in adult males at the University of Port Harcourt Teaching Hospital (UPTH), Nigeria. Material and Methods: The design of the study was cross-sectional and descriptive. Secondary data of patients treated between 01/6/2017 to 30/6/2022, with confirmed diagnosis of USD were used. Their registration numbers were used to access their records at the Health Records Department of the Hospital. Information obtained included sociodemographic data, aetiology, clinical features, types, sites and diagnostic tests of male USD, , uroflowmetry, urethral, and abdominopelvic ultrasonography, cystourethrography results, treatment methods, outcomes, complications and co-morbidities of USD. Data obtained were analyzed with simple statistics and presented. Results: Of 10,450 Urology patients 245 had USD. Data on 224 were found and analyzed. Their age profiles in years were mean, 45.7±18.6; age range 10-95. Married were 174 (77.68%). Urethral strictures were post inflammatory 126(56.25%); post traumatic 43.75%; bulbar,73(32.59%); bulbomembranous23.22%; posterior urethral 52(23.21%); penile 34(15.18%); and pan urethral 13, (5.18%). At presentation, 105 (46.88%) were hypertensive; 40.2% had UTI with Gram-negative bacilli. Recurrence of strictures occurred 6 months to one year after DVIU; 2 months to 6 years after urethroplasty. Non-compliance with schedules and follow-p occurred in 111 (49.55%) patients. Conclusion: USD prevalence was 24/1000 urology patients. UTIs were probably healthcare and prolonged catherization associated. Screening/review of service processes warranted. Lack of validated tools for measurement of outcome or dependent treatment variables made comparative studies unrealistic.

Study on Influence of Mechanical Properties of Concrete based on Microbe Supported in Slag

Concrete material with its own excellent properties, plays a vital role in the construction industry, the annual production of about 10 billion tons, which makes concrete become second only to water, the world's second largest amount of material. However, in the actual service process, all kinds of buildings will be affected by their own and environmental factors, concrete is easy to crack, which affects the mechanical properties of concrete decline, this paper in slag as a carrier of microorganisms on the basis of adding nano-SiO2 in ready-mixed concrete, studied its 3d, 7d, 14d, 28d compressive strength changes. The results show that the strength of concrete can be improved by adding the right amount of nano-SiO2. The addition of nano SiO2 can promote the hydration reaction of cement, resulting in more hydration gelling products of concrete, thus reducing the porosity of concrete and improving the compressive strength of concrete. The results of this study provide an important reference value for the practical application of microbial concrete self-healing.

Elastic and Self-Healing Copolymer Coatings with Antimicrobial Function.

The revolutionary self-healing function for long-term and safe service processes has inspired researchers to implement them in various fields, including in the application of antimicrobial protective coatings. Despite the great advances that have been made in the field of fabricating self-healing and antimicrobial polymers, their poor transparency and the trade-off between the mechanical and self-healing properties limit the utility of the materials as transparent antimicrobial protective coatings for wearable optical and display devices. Considering the compatibility in the blending process, our group proposed a self-healing, self-cross-linkable poly{(n-butyl acrylate)-co-[N-(hydroxymethyl)acrylamide]} copolymer (AP)-based protective coating combined with two types of commercial cationic antimicrobial agents (i.e., dimethyl octadecyl (3-trimethoxysilylpropyl) ammonium chloride (DTSACL) and chlorhexidine gluconate (CHG)), leading to the fabrication of a multifunctional modified compound film of (AP/b%CHG)-grafted-a%DTSACL. The first highlight of this research is that the reactivity of the hydroxyl group in the N-(hydroxymethyl)acrylamide of the copolymer side chains under thermal conditions facilitates the "grafting to" process with the trimethoxysilane groups of DTSACL to form AP-grafted-DTSACL, yielding favorable thermal stability, improvement in hydrophobicity, and enhancement of mechanical strength. Second, we highlight that the addition of CHG can generate covalent and noncovalent interactions in a complex manner between the two biguanide groups of CHG with the AP and DTSACL via a thermal-triggered cross-linking reaction. The noncovalent interactions synergistically serve as diverse dynamic hydrogen bonds, leading to complete healing upon scratches and even showing over 80% self-healing efficiency on full-cut, while covalent bonding can effectively improve elasticity and mechanical strength. The soft nature of CHG also takes part in improving the self-healing of the copolymer. Moreover, it was discovered that the addition of CHG can enhance antimicrobial effectiveness, as demonstrated by the long-term superior antibacterial activity (100%) against Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus aureus) bacteria and the antifouling function on a glass substrate and/or a silica wafer coated by the modified polymer.

A Multi-Agent RL Algorithm for Dynamic Task Offloading in D2D-MEC Network with Energy Harvesting.

Delay-sensitive task offloading in a device-to-device assisted mobile edge computing (D2D-MEC) system with energy harvesting devices is a critical challenge due to the dynamic load level at edge nodes and the variability in harvested energy. In this paper, we propose a joint dynamic task offloading and CPU frequency control scheme for delay-sensitive tasks in a D2D-MEC system, taking into account the intricacies of multi-slot tasks, characterized by diverse processing speeds and data transmission rates. Our methodology involves meticulous modeling of task arrival and service processes using queuing systems, coupled with the strategic utilization of D2D communication to alleviate edge server load and prevent network congestion effectively. Central to our solution is the formulation of average task delay optimization as a challenging nonlinear integer programming problem, requiring intelligent decision making regarding task offloading for each generated task at active mobile devices and CPU frequency adjustments at discrete time slots. To navigate the intricate landscape of the extensive discrete action space, we design an efficient multi-agent DRL learning algorithm named MAOC, which is based on MAPPO, to minimize the average task delay by dynamically determining task-offloading decisions and CPU frequencies. MAOC operates within a centralized training with decentralized execution (CTDE) framework, empowering individual mobile devices to make decisions autonomously based on their unique system states. Experimental results demonstrate its swift convergence and operational efficiency, and it outperforms other baseline algorithms.

The Latency Performance Analysis and Effective Relay Selection for Visible Light Networks.

In visible light communication (VLC), the precise latency evaluation of wireless access networks and the efficient forwarding strategy of core networks are the crux for end-to-end reliability provisioning. Leveraging martingale theory, an elegant latency-bounded reliability analysis framework is studied for the VLC network. Considering the characteristic that VLC links are easy to block, the martingale of the service process is constructed. Based on the time shift features, the martingale process related to latency is proposed for the VLC system, which models the influence of entanglement between aggregate arrivals and random service on latency. A stopping time event about latency is defined. Renting the stopping time theory, a tight upper bound of the unreliability with regard to latency is derived. In the core network, a dynamic forward backhaul framework is proposed, which uses the relay selection algorithm based on back-pressure theory to improve data transmission quality. The theoretical latency-bounded reliability matches the simulation results well, which verifies the effectiveness of the proposed analysis framework, and the proposed relay selection algorithm can also improve network performance under data-intensive transmission.

The Service Experience Innovation Model of Cultural Tourism in Historic Districts: A Case Study on Zhongshan Road in Quanzhou, Fujian Province of China

This study aimed to elucidate how consumers engage in cultural activities in Quanzhou and analyze innovative service experiences in this ancient city. We also sought to create a model integrating humanistic innovations into the enhancement of service experiences. We used an exploratory case study approach, combining secondary data analysis with on-site observations. The findings include the following: (1) The tourist experience in cultural tourism involves six stages: “Connect and Attract”, “Orientate”, “Interact”, “Extend and Retain”, “Advocate”, and “Recollect”. (2) We developed the TESP model for innovative cultural tourism services in Quanzhou, with four dimensions: Technological, Experiential, Systemic, and Platform. The Platform dimension introduces the Hub and Service Process sub-dimensions. Additionally, the study suggests that creating a sense of place in historic districts relies on traditional culture, emphasizing the core competitiveness, identity, and culture of a locality. (3) Integrating “humanistic innovation” into cultural tourism is essential, utilizing digital platforms and interpersonal networks to promote core values and thus foster local economic prosperity. The research outcomes hold practical significance for cultural heritage tourism in Quanzhou, as well as for the study and implementation of service and experience innovations among experience providers, practitioners, managers, and marketing professionals in the field.

The potential of the P-graph for optimizing public service processes

AbstractThe European Union set out several directives and standards for governments and local authorities on environmental policy issues in the planning and management of public services. Public service provisioning is subject to both traditional expectations (such as customer-friendliness and efficiency) and new environmental stewardship and sustainability expectations. This paper analyzes public service processes, particularly the university enrolment process. Our analysis used public service models (Service Blueprinting, Business Process Modeling, Process Chain Network) and a mathematical model (P-graph). Our research aims to analyze the university enrolment process and its efficiency, considering sustainability aspects and expectations and identifying the points that can be modified and improved to make it more efficient, sustainable, qualitatively positive, and economical. According to our research, school administrators are overburdened during the enrolment process, often resulting in overtime work and a high turnover ratio. Our results clearly show the high inefficiency of this administrative process, as administrators can only partially meet their expected labor targets during their regular working hours. We found that the university enrolment process can be improved and made more efficient and sustainable. Using the P-graph, we have found the process’s optimal path and resource requirements in a way that was not feasible with previous models. Heartened by these results, we propose introducing and applying the P-graph as a new model to study other public service processes. Graphical abstract
