The heavens declare (mesaprim) the glorf Un, 04 of God, firmament trakiah) relates (magid) His handiwork. Day to day makes utterance, night to night speaks out. There is no utterance, there are no words, whose sound goes unheard. Their voice carries throughout the earth, their words to the end of the world. He placed in them a tent for the sun, who is like a groom coming forth from the chamber, like a hero, eager to run his course. His rising-place is at one end of heaven, and his circuit reaches the other; nothing escapes his heat. The teaching of the LORD is perfect, renewing life; the decrees of the LORD are enduring, making the simple wise; The precepts of the LORD are just, rejoicing the heart; the instruction of the LORD is lucid, making the eyes light up, The fear of the LORD is pure, abiding forever; the judgments of the LORD are true, righteous altogether (Psalm 19: 2 - 10).

The snow ablation optimizer (SAO) is a meta-heuristic technique used to seek the best solution for sophisticated problems. In response to the defects in the SAO algorithm, which has poor search efficiency and is prone to getting trapped in local optima, this article suggests a multi-strategy improved (MISAO) snow ablation optimizer. It is employed in the unmanned aerial vehicle (UAV) path planning issue. To begin with, the tent chaos and elite reverse learning initialization strategies are merged to extend the diversity of the population; secondly, a greedy selection method is deployed to retain superior alternative solutions for the upcoming iteration; then, the Harris hawk (HHO) strategy is introduced to enhance the exploitation capability, which prevents trapping in partial ideals; finally, the red-tailed hawk (RTH) is adopted to perform the global exploration, which, enhances global optimization capability. To comprehensively evaluate MISAO's optimization capability, a battery of digital optimization investigations is executed using 23 test functions, and the results of the comparative analysis show that the suggested algorithm has high solving accuracy and convergence velocity. Finally, the effectiveness and feasibility of the optimization path of the MISAO algorithm are demonstrated in the UAV path planning project. [ABSTRACT FROM AUTHOR]

The precision of workpiece machining is critically influenced by the geometric errors in the kinematics of grind robots, which directly affect their absolute positioning accuracy. To tackle this challenge, this paper introduces a logistic-tent chaotic mapping Levenberg Marquardt algorithm designed to accurately identify and compensate for this geometric error. the approach begins with the construction of a forward kinematic model and an error model specific to the robot. Then the algorithm is adopted to identify and compensate for the geometric error. The method establishes a mapping interval around the initial candidate solutions derived from iterative applications of the Levenberg Marquardt algorithm. Within this interval, the logistic-tent chaotic mapping method generates a diverse set of candidate solutions. These candidates are evaluated based on their fitness values, with the optimal solution selected for subsequent iterations. Empirical compensation experiments have validated the proposed method's precision and effectiveness, demonstrating a 6% increase in compensation accuracy and a 47.68% improvement in efficiency compared to existing state-of-the-art approaches. This process not only minimizes the truncation error inherent in the Levenberg Marquardt algorithm but also significantly enhances solution efficiency. Moreover, simulation experiments on grind processes further validate the method's ability to significantly improve the quality of workpiece machining. [ABSTRACT FROM AUTHOR]

Given the persistent safety incidents in operating rooms (ORs) nationwide (approx. 4,000 preventable harmful surgical errors per year), there is a need to better analyze and understand reported patient safety events. This study describes the results of applying the Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS) supported by the Teamwork Evaluation of Non-Technical Skills (TENTS) instrument to analyze patient safety event reports at one large academic medical center. Results suggest that suboptimal behaviors stemming from poor communication, lack of situation monitoring, and inappropriate task prioritization and execution were implicated in most reported events. Our proposed methodology offers an effective way of programmatically sorting and prioritizing patient safety improvement efforts. [ABSTRACT FROM AUTHOR]

In this study, the standard tent used by the China International Medical Team (Sichuan) was used as the research object to study the internal temperature change in medical tents in a low-temperature environment relying on heating equipment. Method: Four temperature sensors were arranged along the horizontal direction at a 1.2 m height in the medical tent, and more sensors were installed at heights of 0.1, 0.2, 0.6, 1.2, 1.8, 2.4, and 2.5 m. A total of 11 temperature sensors were set. Temperature tests were conducted in January and February 2021 in Chengdu, Sichuan Province. During the test, the running time of the heating equipment was controlled in real time according to the temperature change trend. A Kolmogorov–Smirnov(K-S) test was used to verify the reliability of the experimental data. The temperature change trend was used to characterize the influence of the heating and cooling equipment on the temperature change inside the tent. Results: Due to the position angle of the heating equipment and the influence of the external environment, the spatial distribution of the ambient temperature inside the medical tent was obviously uneven. In winter, an electric heater with a heating power of about 2500 W can increase the internal temperature of the tent to 16.7 °C, significantly improving the internal thermal environment of the medical tent. The ambient temperature in the medical tent is positively correlated with the height and the installation position of the heating equipment. Conclusion: Medical tents can maintain the ambient temperature well to meet medical needs with the support of heating equipment with sufficient power. The temperature distribution law of medical tents in this experiment has good guiding significance for the placement angle of heating equipment and the configuration position of medical equipment and provides a reference for the development of thermal insulation materials for medical tents.

The NoMA Business Improvement District (BID) is one of Washington DC's fastest developing areas and has one of the city's largest concentrations of unhoused tent camps, many of which are located in underpasses that provide bits of protection and privacy. These underpasses were created during DC's City Beautiful Movement and have been the site of neoliberal antihomeless strategies. In this paper I explore the production of space in the NoMA area and how property owners, business associations, and government actors sanitized public space for wealthy newcomers while excluding poor and unhoused residents.

A study proposed an improved war strategy algorithm called the chaos genetic manifestation war strategy algorithm (CGM-WSO) to extract parameters of solar cell model. The CGM-WSO algorithm incorporates three improvement measures. First, it introduces the logistic–tent chaos map to enable random perturbation during initialization. Second, it utilizes the crossover and mutation operators of the genetic algorithm to enhance the algorithm's ability to escape local optima. Finally, the Lambert W function is employed to obtain explicit analytic expressions of single and double diode models. The performance of the CGM-WSO algorithm was validated using several cell's models, and the results demonstrated significantly improved accuracy, reliability, and convergence speed compared to other algorithms.

Emergency tents face challenges in harsh weather conditions and sometimes require the use of air conditioning for indoor thermal environment control. However, their lightweight structure makes their control methods different from conventional buildings. This study focuses on the indoor thermal environment and thermal comfort of air-conditioned tents during summer. Through experimental measurements, this study captures the distribution of air temperatures and inner surface temperatures within a tent, thus providing an understanding of the characteristics of indoor thermal environment in air-conditioned settings. Additionally, the numerical simulations conducted using the ANSYS FLUENT 2021 R1 calculate the Predicted Mean Vote (PMV) and Predicted Percentage Dissatisfied (PPD), thus contributing to a detailed analysis of the indoor thermal comfort states. The experiment revealed that the mean radiative temperature (MRT) inside the tent can exceed the air temperature by more than 10 °C. Even when the air temperature is around 26 °C, the excessively high MRT can cause occupants to feel uncomfortable, with the PMV exceeding 1.4 and the PPD surpassing 50%. Furthermore, the high MRT results in an increased demand for cooling airflow, with the cooling loss through gaps becoming a significant part in the cooling load. To ensure a comfortable thermal environment, the air-conditioning set temperature needs to be adjusted according to the weather conditions. For instance, even at the same air temperature of 35 °C, when solar radiation increases from 400 W/m2 to 1000 W/m2, the set temperature needs to be reduced from 24.7 °C to 20.7 °C. The findings of this study provide an important reference for establishing summer air-conditioning strategies for emergency tents. [ABSTRACT FROM AUTHOR]

This paper presents research on design challenges in protracted refugee camps, where "temporary" shelters undergo informal transformations, becoming long-term homes and establishing communities. We develop a shape grammar to investigate this phenomenon, focusing on the evolution of refugee housing units in the Irbid Camp in Jordan from the emergency to the transitional and permanent phases. Our parametric shape grammar analyzes and describes the physical characteristics of these units, revealing their dynamic nature. The corpus of the grammar includes 10 diverse housing units that provide a range of insights and opportunities for refugee housing design and planning. The grammar builds a foundation for developing design solutions that mediate transformations and address long-term implications for sustainable and adaptive environments to anticipate self-build processes and better support evolving resident needs in housing layouts.

A quantitative analysis of 150 Mesolithic dwellings in Norway, dated to between 9500 and 4000 cal bc, forms the core of a chronological and regional study based on fifteen variables, including floor size and shape, floor modifications and wall features, internal hearths, numbers and distribution of artefacts, traces of maintenance or reuse, and the number of dwellings per site. The study identifies a distinct change in dwelling traditions between the Early and Middle Mesolithic, around 8000 cal bc. Tents are typical of the Early Mesolithic, whereas remains of pit houses dominate in all later phases of the Mesolithic. The study also sheds light on variability in dwelling traditions after 8000 cal bc, which appears to relate to changes in social structure, growing territoriality, and regional differences.

This article explores the significance of Tent/Freedom Cities as a form of Black place-making and anti-racist activism during the Civil Rights Movement. It specifically focuses on two Tent/Freedom Cities in Fayette County, Tennessee, and Lowndes County, Alabama, which were established to provide housing for Black sharecroppers and tenant farmers who were evicted due to their involvement in civil rights activities. The article argues that teaching about these encampments is important in order to shed light on a lesser-known aspect of the Civil Rights Movement and to examine the relationship between civil rights struggles and the creation of home. It provides background information, primary sources, and teaching resources to facilitate the exploration of these alternative Black geographies. By incorporating the stories and experiences of Tent City residents, educators can offer a more comprehensive understanding of the Civil Rights Movement and its impact on Black communities.

Background: Primary care is internationally recognised as one of the cornerstones of health care. During the COVID-19 pandemic, primary care physicians were assigned a variety of tasks and thus made a significant contribution to a country's pandemic response. They were expected to perform a variety of tasks, such as diagnosing and treating people with COVID-19, maintaining health care for all other patients, as well as several public health tasks, such as diagnostic testing and vaccination, protecting patients and staff from infection, and serving as community trusted persons. In Austria, there are no structured levels of care, no definition of the role of the general practitioner during a pandemic is given, and no specific support structures are present. The aim of this study was to assess the views and experiences of primary care physicians regarding supportive and hindering factors for pandemic preparedness in Austria. Methods: Qualitative study using semi-structured interviews. A total of 30 general practitioners were interviewed, with particular attention to an equitable distribution in small, medium and large primary care facilities. Qualitative content analysis was performed. Results: Interviewees described a wide range of infection control, organisational and communication measures that they had implemented. They made changes to practise equipment, found makeshift solutions when supplies were scarce, and established communication and information pathways when official communication lines were inadequate. Conclusion: General practitioners took on essential tasks and showed a high level of understanding of their role in the pandemic response. This was achieved mainly at an informal level and with high personal commitment. Their functioning in the absence of structural regulations and support shows that they had a clear intrinsic understanding of their responsibilities. To ensure reliability and sustainability and to reduce their burden, it will be necessary to clarify the role and tasks of a general practitioner and to provide the necessary support. This concerns both infrastructural support and communication and information strategies. As part of the reform to strengthen primary care, primary care needs to be seen, valued and involved in decision-making processes. [ABSTRACT FROM AUTHOR]
