Empowering decentralized production: A distributed manufacturing system for additive manufacturing processes

This work presents a pilot distributed manufacturing system for decentralized additive manufacturing, focusing on the Interdisciplinary Center for Advanced Manufacturing Systems (ICAMS) capabilities at Auburn University. The paper outlines the first phase of a multi-phase implementation plan and demonstrates the developed capabilities. The vision is to coordinate geographically separated manufacturing facilities as a cohesive unit. In our work, we prioritize instantaneous communication for file and information sharing. The Manufacturing Hub and Remote Cell, two facilities within driving distance, are coordinated in terms of part design, printing, and inspection procedures for a distributed Additive Manufacturing process. To enable coordination between the two facilities, ICAMS addresses three technological needs. These needs consider information sharing, process standardization, and data collection and monitoring. A network attached storage facilitates information sharing, a database-connected graphical user interface streamlines and standardizes the manufacturing process, and a data collection system facilitates process monitoring. The graphical user interface allows for order placement, progress monitoring, and communication updates. The developed phased plan, collaborative workflow, technological solutions, and production protocols demonstrate the potential for decentralized additive manufacturing. Successful integration of communication, design, printing, and quality assurance processes sets the foundation for future advancements in decentralized manufacturing systems.

Challenges in Sustaining Donor Initiated Monitoring and Evaluation System for HIV and AIDS at the Service Delivery Level; Examples from APHIA plus project in Kakamega County

HIV/AIDS remains a major global public health issue, with Sub-Saharan Africa being the hardest hit and housing over 1.7 million people living with HIV. Kenya's long-term success in combating AIDS requires decentralization, allowing counties and local networks to take an active role in developing, implementing, and monitoring evidence-based initiatives. Current frameworks for Monitoring and Evaluating (M&E) HIV/AIDS programs are primarily focused on data collection to inform decisions at the county and national levels. As a result, there's a pressing need to boost M&E capacity at the service delivery level to ensure effective HIV/AIDS programs. This paper interrogates the AIDS, Population, and Health Integrated Assistance (APHIA plus) Western Project's success in enhancing local M&E capacity at the service delivery level in Kakamega County and the challenges of sustaining the gains beyond the project period. The study sampled 110 health facilities offering HIV/AIDS services in Kakamega County. and established It established that the APHIAplus Western Project made significant strides in strengthening the M&E system by establishing M&E departments, improving collection, quality and dissemination of M&E data and hiring trained staff. The study identified the main challenges to the sustainability of the M&E system which included heavy reliance on external funding and inadequate dedicated M&E staff in county health facilities where 62% of staff carrying out M&E functions/duties were hired by the project. It also identified a challenge in the likely compromise to the prerequisites for quality M&E data after the exit of the project since there was no clear transition plan from project to county. The study results indicate that that 70% of the facilities were collecting monthly data using specified tools and storing the data in an automated system. ANOVA yields a statistically significant difference in the length of years the APHIAplus Western project has supported the health facilities and the frequency of M&E data collection at the service delivery level. The study further identified a challenge in the likely discontinuation of fora/platforms organized monthly in 94% of the facilities for dissemination of M&E findings and supported by APHIAplus Western Project. The study recommends increasing the number of dedicated M&E staff in county health facilities by developing a phased transition plan for M&E staff contracted by the project with a clear handover schedule to County Government of Kakamega, and advocating for increased budget allocation for M&E activities at the service delivery level. Additionally, health facilities are encouraged to explore strategies for diversifying funding sources for M&E activities.

A Phased Plan for the Expansion of Hospice and Palliative Care.

Palliative care is a comprehensive approach aimed at improving the quality of life for patients and their families. The symptom burden and care needs of patients with end-stage, non-malignant diseases are similar to those experienced by patients with advanced cancer. Therefore, the World Health Organization (WHO) has recommended the expansion of palliative care to encompass a broad spectrum of diseases. However, in Korea, the adoption of palliative care for non-malignant conditions remains markedly low, presenting numerous challenges that differ from those associated with cancer. Key barriers to implementing hospice care for non-malignant diseases include the difficulty in predicting end-of-life and a general lack of awareness about hospice palliative care among healthcare providers, patients, and their families. Additionally, there is a risk that suggesting palliative care to patients with non-malignant diseases might be misinterpreted as an endorsement by healthcare providers to cease treatment or abandon the patient. This article explores strategies to broaden the scope of hospice and palliative care for patients with non-malignant diseases.

Flood Analysis on Lake Tempe, South Sulawesi

Tempe Lake is one of the largest lakes in Wajo, Sopen, and Siddenreng Rappang in southern Sulawesi. Lake Tempe is the reservoir of his five major rivers: Bilokka, Lidaratangu, Masaka, Siddenreng, Bira and Walane. The lake offers many benefits to the community such as securing water resources, flood control, agriculture, fishing, and tourism. However, approximately 20–40 cm of silt is produced annually. This can cause flooding in the surrounding areas. Therefore, the restoration of Lake Tempe is necessary to mitigate flooding caused by continuous sedimentation. The Department of Public Works and Housing has developed a phased dredging plan to improve the capacity of Lake Tempe. Later, as no disposal sites were available, dredged materials were used to build several artificial islands along the perimeter of the lake. After the reconstruction project was completed, two major floods occurred, overtopping embankments. Therefore, the design analysis of embankments is required. Analysis indicates that two flood events occur, with a 20-year return period flood and a 50-year return period flood at elevations of 8.36 m and 9.2 m. From hydraulic analysis it is found that flood embankment height of 10 m is overtopped by water level of total 9.56 m and 10.4 m respectively because of wave run up. For a 20-year return period, there is an indication that slope stability and settlement problems affect flood events. It can be concluded that flood problems occur because of extreme events and the failure of flood embankments due to overtopping.

Comparative assessment of a phased debridement strategy amidst treatment for masticatory muscle spasticity in children with cerebral palsy

Relevance. Dental care for children diagnosed with cerebral palsy (CP) presents substantial challenges to dental practitioners. These children not only necessitate individualized care strategies but also face challenges in mouth opening due to masticatory muscle spasticity, which limits operational access during treatments. This study introduces a phased approach to debridement that is integrated with interventions aimed at alleviating hypertonia in the masticatory muscles through adaptive myogymnastics and the use of a pneumatic mouth expander.Materials and methods. A clinical and functional assessment of the orofacial region was conducted on 34 compliant CP patients aged 6-12 years, with the mean age being 9.6 ± 0.3 years. These assessments considered the extent of motor activity and movement limitations in daily activities. Follow-up evaluations were performed six months post-intervention.Results. The phased debridement plan demonstrated significant effectiveness, integrating diagnostic and therapeutic strategies with tailored visitation schedules based on the clinical conditions of the patients.Conclusion. Uniform diagnostic and therapeutic protocols are recommended to enhance dental health and restrain the prevalence of dental diseases among children with spastic cerebral palsy.

Analysis of natural organic matter chemistry in bentonite clay under compaction using different dry densities and duration

The Nuclear Waste Management Organization of Canada has adopted an adaptive phased management plan for the long-term storage of used nuclear fuel in a Deep Geological Repository (DGR). The DGR barrier system employs copper-coated used fuel containers (UFCs) surrounded by buffer material which is composed of highly compacted bentonite clay. The natural organic matter (NOM) composition of the compacted bentonite is of practical importance for the safety assessment as it regulates the biogeochemical processes at the interface between the UFCs and the buffer layer. However, insufficient investigations on NOM constituents limits the understanding of biogeochemical dynamics in bentonites compacted under different dry densities. This study analyzed the carbon content and NOM composition using targeted compound analysis and solid-state 13C nuclear magnetic resonance (NMR) spectroscopy with bentonites compacted at 1.1, 1.4 or 1.6 g/cm3 dry density for 1, 3, 6, 12 or 18 months. Organic carbon contents were similar across bentonites with different compaction densities at various durations as compared to the reference clay (powdered bentonite sample before compaction). The overall NOM composition measured by solid-state 13C NMR suggested a predominance of alkyl and aromatic carbon in bentonite samples. No marked variations were observed for the NOM components (i.e., alkyl, O-alkyl and aromatic carbon) between the compacted bentonites and the reference clay. Targeted compound analysis revealed that the extractable lipid concentrations in the compacted clays did not significantly vary from the reference bentonite with only some compounds exhibiting nano-gram level differences. Bentonites with relatively lower dry densities (1.1 and 1.4 g/cm3) demonstrated slightly higher extractable compound concentrations, but these differences were not statistically significant. In contrast, the compound concentrations of bentonites compacted to 1.6 g/cm3 were similar or slightly lower compared with the reference bentonite, likely associated with limited microbial growth under high dry compaction density. Taken together, these results suggested that NOM composition and quantity did not significantly alter in bentonites under various pressures nor with longer experimental durations. These findings highlight that compacted bentonite exhibited geochemical stability under the simulated repository environments, which provides critical insight for design and performance of engineered barrier system in a DGR concept.

Why germanys energiewende may fail to meet its goals: insights from power system simulation with natural generation

In order to achieve the Paris climate targets, the German government has developed phased plans and anchored these in an amendment to the Renewable Energy Sources Act (EEG). This not only defines expansion targets for renewable energy producers, but also the additional amounts of energy that must be available in the electricity grid in future if it is to supply the mobility and building heating sectors, which are currently still powered by fossil fuels. While the lack of grid transport capacities is recognized and discussed in the public debate, another known and critical hurdle is rarely presented here. This is the temporal distribution of power from renewable energies and its effects on the processes involved in controlling the grid balance. By analyzing a target scenario specified in the EEG for 2030 and another for 2040+, which a German economic research institute recommends to policymakers, the aim is to investigate whether their targets can be achieved under the conditions of the natural fluctuations occurring in Germany and the quantities of renewable energy that can be harvested with a reasonable use of resources. The focus is on simulating future generation curves using historical data in such a way that they show the typical weather-driven behaviour to be expected in Germany. Unavoidable Surplus generation is used as efficiently as possible with electricity and hydrogen storage systems. Both scenarios fall considerably short of their targets. CO2-free coverage of the demand specified for the long-term future is only possible with a quantity of generators that is at the limit of what is feasible. The reason for this is that the current plans are obviously based on an unrealistic picture of the temporal distribution of renewable energy output. Achieving the transformation goals in Germany could be much more complex than politicians currently believe and may require a change in strategy sooner or later.

TRIAXIAL COMPRESSION STUDY OF CLAY SAMPLES

The paper presents a unique method for studying mudstone samples using an independent triaxial compression unit developed at the Department of Oil and Gas Well Drilling, Samara State Technical University. Drilling directional and horizontal wells has difficulties associated with wellbore stability. Stability is directly determined by the strength and deformation characteristics of the rocks, and also takes into account anisotropy, bottomhole pressure and wellbore configuration. In this regard, there are emergency situations at the rig: scree and collapse of the walls of wells in the intervals of unstable rocks. The purpose of the study is to study the core properties to prevent these complications during the design phase. Analysis of rock compression test methods was performed. The method of study is physical modeling of mountain stress at the plant for triaxial compression. The work presents a phased study plan. Analysis of the problem of microcracking of mudstones was also carried out. Based on the design characteristics of plant classes for independent triaxial loading, the installation of the second class with multi-stop systems was chosen. At this stage, the installation is equipped with software. Experiments were carried out according to the first loading program, that is, first the core sample was uniformly compressed along all three axes in one position, and then in a turned position on the 90º. Pressure versus displacement plots were obtained. After processing the results, you can find the Poisson ratio, Young’s modulus, and shear modulus, as well as determine anisotropy. In the future, it is planned to conduct experiments on core saturation.

Flexible facility requirements for strategic planning of airport passenger terminal infrastructure

Facility requirements determine how and when the capacity of airport passenger terminal facilities is adjusted over time to meet expected demand. Given high levels of uncertainty inherent in long-term airport planning, under and over provision of capacity is a recurrent risk, as conventional strategic planning methods fail to adapt dynamically to changing circumstances. This paper introduces a novel flexible capacity expansion model for airport terminals that considers simultaneously real options ‘on’ and ‘in’ systems. The model is validated for the provision of check-in facilities at Zurich Airport. Results confirm suggestions in the literature that incorporating flexibility creates planning and financial advantages over conventional alternatives. Indeed, for the case of Zurich, the financial value of the flexible alternative is approximately 5% higher than the best conventional phased plan. This also suggests that phasing developments can be carefully devised to produce satisfactory outcomes that enable ex-post application of flexibility ‘on’ systems.

The mobile vaccine equity enhancement program-a model program for enhancing equity in vaccine availability based at a large health care system.

The SARS CoV-2 (COVID-19) pandemic presented unprecedented challenges as communities attempted to respond to the administration of a novel vaccine that faced cold chain logistical requirements and vaccine hesitancy among many, as well as complicated phased rollout plans that changed frequently as availability of the vaccine waxed and waned. The COVID-19 pandemic also disproportionately affected communities of color and communities with barriers to accessing healthcare. In the setting of these difficulties, a program was created specifically to address inequity in vaccine administration with a focus on communities of color and linguistic diversity as well as those who had technological barriers to online sign-up processes common at mass vaccination sites. This effort, the Mobile Vaccine Equity Enhancement Program (MVeeP), delivered over 12,000 vaccines in 24 months through a reproducible set of practices that can inform equity-driven vaccine efforts in future pandemics.

 Literacy.

Integrating blockchain with building information modelling (BIM): a systematic review based on a sociotechnical system perspective

PurposeThe purpose of this paper is to analyse the current state of research on the integration of blockchain and building information modelling (BIM) in the Architecture, Engineering, Construction and Operations (AECO) industry as a means of identifying gaps between the existing paradigm and practical applications for determining future research directions and improving the industry. The study aims to provide clear guidance on areas that need attention for further research and funding and to draw academic attention to factors beyond the technical dimension.Design/methodology/approachA mixed-method systematic review is used, considering multiple literature types and using a sociotechnical perspective-based framework that covers three dimensions (technic, process and context) and three research elements (why, what and how). Data are retrieved and analysed from the Web of Science and Scopus databases for the 2017–2023 period.FindingsWhile blockchain has the potential to address security, traceability and transparency and complement the system by integrating supporting applications, significant gaps still exist between these potentials and widespread industry adoption. Current limitations and further research needs are identified, including designing fully integrated prototypes, empirical research to identify operational processes, testing and analysing operational-level models or applications and developing and applying a technology acceptance model for the integration paradigm. Previous research lacks contextual settings, real-world tests or empirical investigations and is primarily conceptual.Originality/valueThis paper provides a comprehensive, critical systematic review of the integration of blockchain with BIM in the construction industry, using a sociotechnical perspective-based framework which can be applied in future reviews. The study provides insight into the current state and future opportunities for policymakers and practitioners in the AECO industry to prepare for the transition in this disruptive paradigm. It also provides a phased plan along with a clear direction for the transition to more advanced applications.

AUCKLAND COUNCIL’S PROGRESS ON SUSTAINABLE SHORELINE ADAPTATION PLANS

Auckland Council is currently developing shoreline adaptation plans across the Auckland region to support the sustainable management of public assets into the future with increasing coastal hazard risks. These build upon the Coastal Management Framework (Carpenter et al. 2017) and are being developed as 20 phased plans. At the time of writing the ‘Whangaparāoa’ and ‘Beachlands and East’ Shoreline Adaptation Plans (SAP) have been completed. The ‘Āwhitu Peninsula’ and ‘Manukau South’ SAPs are well underway, and the remaining SAPs are programmed to be completed over the next 4 years. To inform the development of the adaptation strategies numerous datasets were required. Coastal erosion and coastal flooding predictions have been mapped for the Auckland region to assess the evolving coastal hazards. Up-to-date coastal asset information was gathered through hundreds of coastal asset inspections for each SAP area. This asset data fed into adaptation strategy decisions as well as being incorporated into a regional risk assessment to assess the relative risk across Auckland’s SAP units.

Failure mechanism and stability control of surrounding rock in mining roadway with gentle slope and close distance

In this study, theoretical analysis, numerical simulation and field measurement were adopted to analyze the difficult problem of controlling the stability of surrounding rock in gently inclined and close-distance coal seam mining roadways. The results showed that: (1) According to the properties and stress environment of the roadway roof, to determine the specific spatial range of the original roof stage, transition stage and regeneration roof stage of the roadway, and corresponding to the distribution of plastic zones in the spatial stages, was an important basis for analyzing the deformation mechanism of the roadway and proposing a phased collaborative control plan. (2) Under the influence of mining, the plastic zone of the transportation roadway expanded violently by about 10 m ahead of the working face. Within the range of roadway passing the overlying goaf, the plastic zone of the surrounding rock between the layers runed through, especially extending to the roof and two shoulder corners of the roadway. The roof and two shoulder corners of the roadway became the key parts for the stability control of the surrounding rock. (3) The mechanical mechanism of asymmetric expansion of the plastic zone was obtained as follows: the range was determined by the magnitude of the deviatoric stress and the orientation was dominated by the direction of the principal stress. The combined effect of the magnitude of deviatoric stress and the angle of principal stress caused asymmetric expansion of the plastic zone. (4) A phased collaborative control scheme was proposed, and numerical simulation and industrial verification were carried out on the proposed scheme. The deformation of the surrounding rock of the roadway at the engineering site was less than 150 mm, and the control effect of the surrounding rock was good, ensuring the safe and efficient recovery of the fully mechanized mining face. The present study revealed the mechanical mechanism of failure and instability of the surrounding rock of the gently inclined close distance coal seam mining roadway and proposed a phased collaborative control scheme, which could provide valuable information for mining research.

The pilot study of retail segment of CBDC has commenced from the beginning of December 01, 2022. This paper made an attempt to delve into the understanding of Central Bank Digital Currency and to probe the motives behind the issuance of CBDC. RBI is currently working toward a phased deployment plan, progressing gradually through several rounds of pilots before the final launch and concurrently looking at use cases that might be adopted with little to no impact.

A honey bee requirements design study based on multi-objective optimization

The honeybee is a major pollinating insect and plays a vital role in the ecological chain. Therefore, the correct prediction of honeybee population size and optimal beehive configuration is beneficial for developing long-term or phased management plans for bee colonies to obtain high yields of bee products. Through literature analysis, this paper chooses economic benefits and environmental effects as the multiple objectives of the model. The model is also constrained by the maximum number of bees pollinating and the minimum daily pollen consumption of bees to calculate the optimal number of beehives for a given area. In this paper, we adopt the multi-objective equal-weight processing and transform it into a single-objective approach, which is solved using the artificial bee colony algorithm. According to the final calculation, the optimal number of beehives for this area is 54.

THE SPATIAL-TEMPORAL DISTRIBUTION OF BRICK MATERIAL RESOURCES IN BRICK-CONCRETE-STRUCTURED HOUSING IN INNER TIANJIN CITY

ABSTRACT Determining how to reasonably protect, upgrade, or rebuild old communities, deciding how to use the material resources they contain, and the generation of construction and demolition (C&D) waste are urgent problems faced in the process of urban renewal in Tianjin, China, that require solutions. In this study, brick and concrete housing structures in the downtown area of Tianjin, China, are considered as an example, and a phased renewal plan is proposed. Based on the nuclear density analysis method and the standard deviation ellipse method, the spatial agglomeration trends and distribution directions of the used bricks that will be produced in the city center during each demolition stage are investigated. The results demonstrate that the overall brick material resources are unevenly distributed; their density will increase over time, and the density core will present a trend of first gathering and then dispersing. Based on the spatiotemporal distribution of resources, it is necessary to formulate an urban resource recycling system to achieve sustainable development.

Decoding COVID-19 Vaccine Hesitancy Using Multiple Regression Analysis with Socioeconomic Values.

With the growth and development of COVID-19 and its variants, reaching a level of herd immunity is critically important for national security in public health. To deal with COVID-19, the United States has implemented phased plans to distribute COVID-19 vaccines. As of November 2022, over 80% of Americans had received their first shot to guard against COVID-19, and 68.6% were considered fully vaccinated, according to the dataset provided by CDC. However, a significant number of American people still hesitate to receive a shot of the COVID-19 vaccine. This paper aims to demystify COVID-19 vaccine hesitancy by analyzing various socioeconomic characteristics among individuals and communities, including unemployment rate, age groups, median household income, and education level. A multiple regression modeling and data visualization analysis show patterns with an increasing trend of vaccine hesitancy associated with a lower median household income, a younger age group, and a lower education level, which would help policymakers to make policies accordingly to target vaccine support information and remove this hurdle to end the COVID-19 pandemic effectively.
