Design Of Safety Signs Using Ergonomic Function Deployment Method At PT.XYZ

PT. XYZ is a company engaged in manufacturing by processing raw materials into semi-finishedgoods or finished goods. Because the company routinely produces these products and involvesmachinery, it will allow small to serious work accidents to occur. Based on the hazard event dataowned by the company, there are 5 very diverse events that will be analyzed in the risk controlhierarchy to minimize hazard events. The results of the risk control hierarchy analysis have two hazardevents that have safety sign design criteria. Therefore, research was conducted to design safety signsin the area of explosive materials and loading progress in minimizing hazard events using safety signsassessment and Ergonomic Function Deployment approaches. The data needed in the design areanthropometric data, layout data, customer statements and level questionnaires interest andsatisfaction. From the results of the safe sign assessment, the signal word is obtained, determining thelocation, height, model, and material of the safety signs. The results of the safety signs assessmentwill be used for the Ergonomic Function Deployment approach. From the results of the ErgonomicFunction Deployment, the results obtained are the size of safety signs, safe reading distance, type oflayout, use of language and font size on safety signs. There are two types of designs, namely explosivematerial and loading progress safety signs. The design of safety signs refers to the ANSI Z535standard so that the design of safety signs has detailed signal words, symbols, signs, and wordmessages.

Coupling dynamic characteristics of installation vessel - Multi buckets jacket foundation lowering system

Precise control of the splash zone lowering process of the multi-bucket jacket foundation for an offshore wind turbine can save time during the entire construction period, thereby reducing construction and installation costs. This paper focuses on the “installation vessel - multi buckets jacket foundation” coupled dynamic system during the lowering process of the multi-bucket jacket foundation. Taking the three-bucket jacket foundation (TBJF) and the four-bucket jacket foundation (FBJF) as the research objects, four different sling layout types were proposed. The influence of the slings layout types on the motion response of the installation vessel and foundation and the slings' tension in this system were comparatively studied through numerical simulation. Research shows that through the lowering of Type 1 conditions, that is, each chord corresponds to a vertical sling and is directly connected to the crane's lifting point, the motion performance of the foundation and installation vessel can be reduced, ensuring the smooth progress of the lowering process of the structure. Under the same conditions, the FBJF has greater motion response due to the large wave force bearing area and large water plane area. Under different conditions, the DAF value and failure factor of the slings of the two structures during the lowering process all meet the specification requirements.

Optimization of speech intelligibility in street-facing rooms of adult care home based on acoustic simulation

Due to the limited availability of urban land in China, many adult care facilities have resorted to constructing roadside living spaces. However, this has led to a significant issue of traffic noise disturbance. Besides, many rooms lack of control over indoor reverberation. As a result, the communication efficiency of the residents might be greatly impacted. This study aims to investigate the impact of traffic noise level, room size, and surface sound absorption on speech transmission index (STI), based on a typical room layout and conducted using acoustic simulation. The simulation results indicated that in order to achieve the required STI over 0.79 for elderly residents, it is imperative to control the road noise interference below 40 dBA and ensure that the room reverberation time under 0.42 s. To achieve this, it is recommended that for a road with a noise emission level of 72 dBA, the distance between the roadside room and the road should not less than 10 m. Additionally, windows with Rw+Ctr over 28 dB without road sound barriers (over 20 dB with sound barriers) should be installed. Besides, the room area needs to be controlled within 20 m2 and an acoustic ceiling with NRC>0.65 should be installed.

A novel improved actuator line method for tandem-arranged wind turbines wake analysis and its application

For a typical wind farm layout, the disturbance caused by wind turbine wakes typically exerts a significant negative impact on power generation. However, due to the insufficient reliability of existing multiple turbines wake simulations, the improved effects of wind farm layout modifications cannot be fully verified. In this paper, we employ a high-fidelity model, the Improved Actuator Line Model (I-ALM), combined with Large Eddy Simulation (LES) based on the OpenFOAM solver, to investigate the active yaw strategy of wind farms. The improvements in the ALM primarily include the Gaussian anisotropic force projection method, the integral velocity sampling method, and the enhanced nacelle-tower projection method. Firstly, we conduct numerical simulations of the NTNU "Blind Test" experimental cases using the combination of the I-ALM method and LES, mainly focusing on aerodynamic forces and wake development characteristics. Then, the proposed method is applied to the wake prediction of three NREL 5 MW tandem-arranged yaw wind turbines after benchmarking. The power generation and wake characteristics under different yaw angles is comprehensively predicted, leading to the development of a preliminary active yaw strategy (including rated state and maximum TSR state). This strategy holds significant guiding value for the accurate and efficient simulation of wind farms.

An agent-based approach to simulating evacuation in elderly care facilities with disabled older adults

Emergencies in elderly care facilities are not uncommon. However, conducting evacuation drills for disabled older adults poses significant challenges due to their physical limitations. While simulation approaches offer a viable alternative, there is a dearth of research focused on evacuation simulation models considering the presence of disabled older adults. This study introduces an agent-based approach designed to simulate the evacuation of older adults within elderly care facilities. The approach incorporates the distinct characteristics and behaviors of nursing staff, self-sufficient, semi-disabled, and disabled older adults during evacuation. The simulation environment replicates the typical architectural layout of single-story elderly care facilities. Two evacuation strategies, specifying the order in which nursing staff assist disabled older adults during evacuation, are proposed. The performance of these strategies under scenarios with varying proportions of disabled older adults and caregiver ratios is compared through simulation experiments. The results indicate that the strategy requiring nursing staff to initially assist the disabled older adults under their responsibility and then seek out and aid the nearest disabled older adults is more effective in reducing total evacuation time in most cases. Furthermore, the impact of the spatial layout of disabled rooms on evacuation efficiency and safety is discussed. The results reveal that the opposite-side center concentration pattern of disabled rooms outperforms other spatial layout patterns of disabled rooms in terms of evacuation efficiency and safety. These findings contribute to the optimization of evacuation strategies and spatial layouts within elderly care facilities by providing quantitative evidence to support decision-makers.

Hydraulic analysis of advanced spillway systems in tailings dams under extreme weather conditions

With the increasing frequency of extreme weather events, heavy rainfall and flooding pose significant pressure on the flood discharge systems of tailings dams. Simple discharge systems are insufficient to meet the flood discharge requirements of tailings dams, while complex discharge systems, with their greater flood discharge capacity, are gradually being promoted. Although complex discharge systems can increase the flood discharge capacity of tailings dams, the flow patterns within the discharge systems become more complex. As a new type of discharge system layout, existing research lacks systematic analysis, and its complex flow characteristics are not clear. This paper relies on the flood discharge system of a large tailings dam to carry out theoretical calculations and derivations of the hydraulic characteristics of the complex flood discharge system. Hydraulic characteristics are observed through hydraulic model tests and verified using numerical simulations. Based on these three methods, a basis for further research on the hydraulic characteristics of complex flood discharge systems is provided. The main results are as follows: (1) The formulas for calculating the discharge flow rate Q under different flow states in the tailings dam design manual are not applicable to complex discharge systems; (2) Formulas for calculating the discharge flow rate Q under different flow states in complex discharge systems are proposed; by comparing model test values and numerical simulation values, the accuracy of the formulas for calculating the discharge flow rate Q in complex discharge systems is verified; (3) If the traditional mode is used to calculate the discharge flow rate Q in complex discharge systems, it is recommended to take the reduction coefficient as 0.55–0.56, and the model test values should also be referred to during flow state transitions.

Design And Build A Mobile-Based Calligraphy And Inscription Order Customize Application With The Waterfall Method Using Fabric JS

Mobile-based apps have become one of the most important aspects of daily life and even for spiritual and aesthetic purposes such as ordering calligraphy and inscriptions. This also had an impact on the Inscription Blessing Shop. In recent years, the demand for personalized calligraphy and inscriptions has increased significantly. However, this store experienced problems in the ordering process. The process of ordering calligraphy and inscriptions is often still done conventionally, where consumers have to come to the store to place an order which may take a long time and is inefficient. To overcome these obstacles, an effective and efficient system is needed by designing and building a mobile-based booking application. This application will be designed using the waterfall development method by utilizing Fabric JS technology as an interface design. The results of this study were obtained that a mobile-based application called the Blessing Inscription Application was formed which can order inscriptions and other carvings anywhere and anytime. The app can allow users to select different types of calligraphy fonts, set layouts, and add decorative elements. This research is expected to make a significant contribution in facilitating users' creativity and enriching their experience in designing and sharing calligraphy works and digital inscriptions.

Impact of Urban Morphology on High-Density Commercial Block Energy Consumption in Severe Cold Regions

In sustainable city development, urban form plays an important role in block energy consumption, and as different environmental contexts and block functions create differences in energy use, it is necessary to study the relationship between morphology and energy consumption under the dual constraints of special environments and special block functions. Urban high-density blocks have concentrated energy consumption, high energy intensity, and complex morphological layout, but the influencing mechanism of the block’s morphology on its energy consumption remains unclear. Accordingly, this study focuses on the mechanism and evaluation method of the influence of morphology on the energy consumption of high-density commercial blocks in severe cold regions. Through Grasshopper model extraction, EnergyPlus performance simulation, Pearson correlation analysis, and linear regression analysis, this study extracts and classifies high-density commercial blocks in Harbin, China, into six basic layout types (Courtyard, Courtyard-T, Slab, Slab-T, Point, Point-T) according to their horizontal and vertical morphology, analyzes the energy consumption characteristics of each basic type, examines the relationships between energy use intensity (EUI) and building density (BD) and between floor area ratio (FAR) and building height standard deviation (BHSD), and constructs theoretical models by controlling variables to study the effect of a single form parameter on block EUI. The research findings are as follows: (1) The annual energy consumption of Point and Slab blocks is relatively low, whereas that of Courtyard and Courtyard-T blocks is higher due to the lack of open space in Courtyards and the poor ventilation in summer. (2) FAR is significantly correlated with the energy consumption of high-density commercial blocks in severe cold regions, while the effects of BD and BHSD are weaker than those of FAR. For every 0.1 increase in BD, every 1 increase in FAR, and every 1(m) increase in BHSD, the Winter Daily EUI of the Slab block changes by +0.87, −2.26, and −0.22 (kWh/m2), respectively, whereas that of the Slab-T block changes by −0.38, +0.68, and +0.08 (kWh/m2), respectively. (3) Controlling other variables, a large BD is theoretically beneficial to energy performance in the blocks, and increasing BD in the range of 0.4–0.55 has a significant effect on lowering energy consumption in Point blocks. EUI increases with the increase in FAR, while the change depends on different block types with the increase in BHSD. This study provides design strategies for high-density commercial blocks in severe cold regions. Under different layout types, though EUI shows different relationships with BD, FAR, and BHSD, Slab-T and Point-T blocks can achieve excellent energy performance by appropriately increasing BD and decreasing FAR, whereas Slab blocks need to decrease BD while increasing FAR. The patterns found in this paper can provide strategic help for policymaking and early urban design.

It aims to provide scientific theoretical support and practical reference for engineering design and achieve more efficient and stable tunnel hydraulic operation conditions.

THE ROLE OF OPEN-AIR CALVARIES IN THE CONTEXT OF LANDSCAPE HERITAGE PROTECTION OF THE EASTERN SUDETES

The article concerns the meaning and landscape functions of Small Calvaries located in the Eastern Sudetes in the border area of the Czech Republic and Poland. The publication aims to indicate the main typological features of this type of calvary, taking into account the current behaviour of residents having a common sarcastic heritage. Due to the subject, interdisciplinary research was undertaken in the direction of valorization as well as environmental interviews. The use of geosociological methodology made it possible to assess the landscape in terms of its contemporary functions and potential threats. The research allowed us to distinguish two types of landscape layouts: elliptical and linear of a historical nature, and modern, mainly linear. Sociological research showed the attitude of local communities to the sacred heritage in the Eastern Sudetes.

Effect of in-plane damage on the out-of-plane strength of masonry walls with openings

Past earthquakes have shown that masonry walls are vulnerable to fail near the openings. Openings such as doors and windows are an essential part of the structure. The presence of an opening reduces the strength and stiffness of the masonry structures. It also affects the load-resistant mechanism of the masonry walls. The walls are subjected to simultaneous in-plane and out-of-plane forces during seismic events. Therefore, the analysis of the masonry walls either in in-plane or out-of-plane direction may not give a proper picture of the global behavior of the masonry structures. The masonry walls deform primarily in the in-plane direction if the walls are properly tied with each other, and the structure is constructed by following codal provisions. Under this situation, it is necessary to investigate the effect of in-plane damage on the out-of-plane strength of the masonry walls. Few researchers have studied the behavior of solid unreinforced masonry walls under combined loading. However, limited work can be found for masonry walls with openings. Therefore, the present study focuses on the effect of different types of opening layouts on the combined in-plane and out-of-plane behavior of masonry walls incorporating varying pre-compression. Further, in masonry buildings, walls are interconnected, making the masonry walls of various shapes. In this study, masonry walls of rectangular and I shapes have been considered to examine the effect of cross-walls under combined loading. Interaction curves have been developed for the walls subjected to the in-plane loading followed by an out-of-plane pressure. Based on the results, the maximum opening percentage in the masonry walls has been suggested, which is desirable in the case of masonry buildings constructed in high seismic zones.

Research on Optimization Design Strategies for Natural Ventilation in Living Units of Institutional Elderly Care Facilities Based on Computational Fluid Dynamics Simulation

As China transitions into a deeply aging society, the elderly population’s growth has driven a rapid increase in elderly care institutions and facilities during the “13th Five-Year Plan” period, rising by over 235% compared to the “12th Five-Year Plan”. The ongoing normalization of COVID-19 prevention measures has underscored the urgent need to improve natural ventilation in elderly care residential facilities. This study conducted empirical surveys to assess the current state of natural ventilation in typical elderly care facilities and analyzed the architectural elements influencing it. By examining the needs and preferences of the elderly for natural ventilation, two basic living space layout types were identified through typological analysis. Suitable CFD simulation software was then employed to model key elements, and effective methods to enhance ventilation were summarized. This study found that modifying the floor plan to reduce the depth of south-facing rooms to 8.4 m, relocating external openings to the center of the rooms, adjusting the ratio of ventilation openings to room area to greater than 1/12, and adding 0.5 m high windows facing internal traffic roads can significantly improve indoor ventilation while maintaining privacy. Furthermore, placing the main activity and resting areas of the elderly in well-ventilated zones with minimal drafts can enhance both comfort and ventilation effectiveness. The research provides a scientific basis and methodological guidance for the construction and renovation of elderly care residential facilities.

Impact of Plant Layout on Microclimate of Summer Courtyard Space Based on Orthogonal Experimental Design

With the rapid development of urbanization and industrialization, many green spaces have been replaced by urban buildings, resulting in decreased green spaces in courtyard space. Nonetheless, as an enclosed green space integrated with the natural environment, courtyard space plays a vital role in regulating environmental microclimate, so it is necessary to study its microclimate through vegetation greening. Therefore, this study took courtyard spaces in humid and hot areas as an example, and with the help of ENVI-met 5.5.1 software, introduced an orthogonal experimental design to simulate various plant layout models, including tree layout (TL), shrub layout (SL), grass layout (GL), and the interaction of their combined layout, and analyzed the simulation results of temperature, humidity, and wind speed. The results show that first of all, plant layout plays a crucial role in cooling and wind control, and the more uniform the plant layout, the better it is for cooling and ventilation. Secondly, plant layout showed a changing pattern of cooling and wetting in the morning, noon, and afternoon periods. Furthermore, TL had the best cooling and humidifying effect in the morning and midday, and the combined interaction of TL, SL, and GL and of SL and GL significantly affected the wind speed in the courtyard space. During the afternoon, the combined interaction of TL with SL and SL with GL outperformed the single-plant-element type of layout regarding cooling and humidification efficiency. Finally, scattered-form tree layout, single-form shrub layout, and 20% grass layout were the best combinations of plant layout for cooling, humidity reduction, and ventilation. The results provide reference data and an empirical case for the microclimate optimization of summer courtyard spaces.

Quantitative risk assessment of gas leakage and explosion in open kitchens and partitioned kitchens

ABSTRACT In recent years, natural gas companies have faced more and more gas supply applications for open kitchens in China. However, natural gas cannot be utilized in open kitchens according to the current compulsory regulations. The numerical models for three typical open kitchen layouts and the corresponding partition kitchen layouts were developed, respectively. The experimental setup of gas leakage and explosion, like a residential kitchen, was established based on the similarity theory. The accuracy and reliability of numerical models have been validated by three sets of experiments. An innovative quantitative risk assessment method was proposed to quantify the integrated risks for the open kitchen layout and the partition kitchen layout. The effectiveness of the proposed risk reduction measures was assessed using a modified LOPA (i.e. Layer Of Protection Analysis). The results show that the integrated risk for the open kitchen layout in different apartments is 1.37 ~ 4.65 times than that for the partition kitchen layouts. The integrated risk of gas leakage explosion in three open kitchen layout arrangements was reduced by 94.8%, 50%, and 94.5%, respectively, by setting two layers of protection. Meanwhile, the increased expense of ¥400 can be generally acceptable for the majority of residential users. The achievements could provide theoretical and technological guidance for gas safety supply in open kitchens.

Loss of insulation vacuum tests on an EuXFEL cryomodule

Many Free Electron Lasers (FEL) are nowadays based on linear superconducting accelerators (linacs). The typical layout of such a linac consists of a number of cryomodules (CMs) arranged in strings. Each cryogenic circuit in a string is protected by safety valves (SVs) in case of failure of the system or a catastrophic event. A typical worst-case scenario considers the venting of the insulation vacuum, causing a fast and uncontrolled warm up of the cryogenic circuits. Such venting can for example take place across a pump port belonging to a string. The amount of heat deposited on each circuit is a very important parameter to correctly size the safety devices.This paper describes the tests performed at DESY on an EuXFEL cryomodule to evaluate the heat input to the three cryogenic circuits of the CM while venting the insulation vacuum. Test results are given with a particular focus of their application to long strings.

Visibility-based layout of a hospital unit - An optimization approach.

Apatient fall is one of the adverse events in an inpatient unit of a hospital that can lead to disability and/or mortality. Themedical literature suggests that increased visibility of patients by unit nurses is essential to improve patient monitoring and, in turn, reduce falls. However, such research has been descriptive in nature and does not provide an understanding of the characteristics of an optimal inpatient unit layout from a visibility-standpoint. To fill this gap, we adopt an interdisciplinary approach that combines the human field of view with facility layout design approaches. Specifically, we propose a bi-objective optimization model that jointly determines the optimal (i) location of a nurse in a nursing station and (ii) orientation of a patient's bed in a room for a given layout. The two objectives are maximizing the total visibility of all patients across patient rooms and minimizing inequity in visibility among those patients. We consider three different layout types, L-shaped, I-shaped, and Radial; these shapes exhibit the section of an inpatient unit that a nurse oversees. To estimate visibility, we employ the ray casting algorithm to quantify the visible target in a room when viewed by the nurse from the nursing station. The algorithm considers nurses' horizontal visual field and their depth of vision. Owing to the difficulty in solving the bi-objective model, we also propose a Multi-Objective Particle Swarm Optimization (MOPSO) heuristic to find (near) optimal solutions. Our findings suggest that the Radial layout appears to outperform the other two layouts in terms of the visibility-based objectives. We found that with a Radial layout, there can be an improvement of up to 50% in equity measure compared to an I-shaped layout. Similar improvements were observed when compared to the L-shaped layout as well. Further, the position of the patient's bed plays a role in maximizing the visibility of the patient's room.Insights from our work will enable understanding and quantifying the relationship between a physical layout and the corresponding provider-to-patient visibility to reduce adverse events.

Conceptual design and configurations selection of S/H-UAVs based on Q-rung dual hesitant double layer FQFD

For the conceptual design phase of Unmanned Aerial Vehicles (UAVs), a process for conceptual design and configuration selection of Solar/Hydrogen powered UAVs (S/H-UAVs) is proposed. The design requirements of S/H-UAVs were analyzed firstly. The proposed process used Fuzzy Quality Function Deployment (FQFD) to establish logical and quantitative standards. Moreover, in order to appropriately describe the hesitancy of experts while making decision, it used Q-Rung Dual Hesitant Fuzzy Sets (QRDHFS) to score the correlationships. In addition, a decision-making framework is proposed to perform a logical selection of typical layouts based on defuzzification method and Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS). The present process has been applied for S/H-UAVs. The resulting set of design requirements consists of three categories: Mission Requirements (MRs), Engineering Characteristics (ECs) and Technical Indicators (TIs). Four typical layouts of S/H-UAVs were sorted and determined. The performance of four typical layouts were evaluated and the Strut-Braced Wing (SBW) with external hydrogen storage was selected as the best layout for S/H-UAVs.

Big Cities, Big Impacts? A spatial analysis of 3,335 ecological offsets in France since 2012

This paper assesses the French policy of mitigation hierarchy, with the aim of no net loss of biodiversity, by studying the geographical aspects of the application of the concept of ecological offsets in equivalence between losses and gains using spatialized data. We seek to know whether the dynamics of urban and interurban development (notably built-up and transport infrastructures) lead to a spatially integrated implementation of biodiversity offsets taking into account local characteristics and areas under pressure from land artificialization. Our main finding reveals that the majority of ecological offsets are generated by projects related to transport infrastructures (38%) and urban planning and construction projects (23%). However, if there are fewer, the ecological offsets of projects such as waste storage or energy development are mostly located in natural preserved areas, revealing a potential risk of non additionnality of offset measures and a risk that the private sector (through ecological offsets) will gradually replace the state in the protection of biodiversity. Our analysis also points out that despite the diversity of projects, habitats and protected species across France, there is a typical spatial layout profile of ecological offsets, pleading for a “one size fits all” offsetting in the French policy context of tenuous regulators’ availability in time and competence level due to weakness of refresh training and downsizing of public services in the environment. This last result argues for a stronger control from environmental agencies between two tremendously tricky concepts of offsetting, the equivalence valuation methods and the adjustments coefficients (time delay and ecological risk), to drive ecological offsetting future decisions at local but above all regional- and national-level planning documents.

Optimization of the building-integrated transparent photovoltaic configuration based on daylight and energy performance in school buildings in the tropics

Introduction: Numerous previous studies addressed the use of vertical facades for side lighting. They were found to be an effective daylighting aperture that helps to establish a pleasant environment, improve academic performance in schools, and promote better health. Recent studies also identified the potential for using vertical facades on high-rise buildings as building-integrated photovoltaic (BIPV) systems thanks to the large available area. In the tropics, this potential use is also supported by the availability of abundant solar energy. The technology of transparent PV (TPV) offers the opportunity to meet both needs. It serves as a side lighting aperture and building-integrated transparent photovoltaic (BITPV) depending on several factors, such as the visible transmittance (VT) value and the number of cells. For side lighting, a higher VT value is required to allow for optimal daylight penetration. However, more cell numbers and lower VT are preferable for BITPV. Previous studies found that BITPV is suggested for buildings with a window-to-wall ratio (WWR) of 45 % or more, which seems too high for tropical buildings where the suggested WWR is typically in the range of 30–40 %. Purpose of the study: This study aims to find the optimum configuration and present a systematic method for optimizing BITPV for tropical school building facades. Methods: An experimental approach using simulation as a tool was employed to achieve the objective. A site with a typical school layout in the tropics was selected as the research context. Treatment based on VT and cell numbers was applied to create several post-test models. Results and discussion: In the tropics, when using low-transparency TPV, BITPV with 31.25 % WWR and 30 % cell coverage ratio is found to provide the optimum visual health and comfort, as well as energy performance. Meanwhile, BITPV with 31.25 % WWR and 50 % cell coverage ratio is found to be the optimum configuration when using high-transparency TPV. Furthermore, this study presents a systematic method for designing BITPV for a multi-story school building in the tropics.
