Stability analysis and support system design of Angouran underground mine batching room

Purpose. The aim of this paper is to develop a numerical model to investigate the stability of Angouran underground mine batching room, in which appropriate support systems are selected, designed, and compared to choose the most optimal case. Methods. Stability analysis is carried out by critical shear strain criterion using finite element method (FEM). The effect of support system on the stability of batching room has been determined for two types of composite support systems: one, incorporating rock bolt and shotcrete, and the other, comprising steel frame with one-meter distancing and shotcrete, based on comparing the displacements around stopes with the amount of critical and allowable strains resulted from Sakurai criterion. Findings. The results of the analysis show that the excavation of the batching room without a support system causes its instability and failure, so it is imperative to design a suitable support system according to the geomechanical and stress conditions of the area. Comparison between the two selected support systems also shows that there is not much difference between these two support systems and in both cases, batching room stability can be provided. Originality. A wide range of parameters involved in the calculation were explored. Results suggest that the failure strain seems to be a promising tool when used correctly. Considerable time saving can be achieved without losing accuracy. Practical implications. Numerical methods can be utilized to analyze tunnels with non-circular cross-sections, considering heterometric ground conditions around the tunnel, often heterogeneous in situ stresses, rock mass behavior and tunnel face effects. By selecting suitable rock failure criteria, it is possible to identify weaknesses around the excavations via numerical modeling and design an appropriate support system based on it.

Design and Definition of a New Decision Support System Aimed to the Hierarchization of Patients Candidate to Be Admitted to Intensive Care Units

The triage processes prior to the assignation of healthcare resources in hospitals are some of the decision-making processes that more severely affect patients. This effect gets even worse in health emergency situations and intensive care units (ICUs). Aiming to facilitate the decision-making process, in this work the use of vague fuzzy numbers is proposed, aiming to define a multi-attribute patient hierarchization method to be used in emergency situations at hospital ICUs. The incorporation of fuzzy models allows for modelling the vagueness and uncertainty associated with decision criteria evaluation, with which more efficient support is provided to the decision-making process. After defining the methodology, the effectiveness of this new system for patient hierarchization is shown in a case study. As a consequence of that, it is proved that the integration of decision-support systems into healthcare environments results to be efficient and productive, suggesting that if a part of the decision process is supported by these systems, then the errors associated with wrong interpretations and/or diagnoses might be reduced.

Revisiting the dewar design for liquid oxygen storage in fuel cell energy systems

Dewars are used to store liquid oxygen (LOX) in a fuel cell-driven Air Independent Propulsion (AIP) system for subsea vehicles. The dewar should have good storability to reduce snorkeling frequency. It is a double-walled vessel in which the two vessels are held together with a support system. The annular space contains the insulation. Heat flows from the ambient into the LOX through the insulation and support systems. Many types of dewar are available commercially; however, there exist no design guidelines in the open literature. Heat inleak is one of the primary concerns in the dewar design. For the first time, a comprehensive study is presented in this paper to highlight the relative importance of the support system and the insulation in dictating the heat inleak into the dewar. We determined the effects of heat inleak on the dewar design. The study revealed that the heat inleak through the support is considerably larger than that through the insulation. The results clearly emphasize the importance of the support system design in improving the storability of the LOX dewars in a fuel cell system.

The management and development of human resources have become one of the core contents of enterprise management. It is from the initial use as an auxiliary tool in human resources business management to the later development of a relatively independent and functional sub-system for the processing of personnel matters between modules, and then to achieve the integration of various sub-systems to form a relatively complete set of human resources information management system. In recent years, with the rapid development of data mining technology, more and more enterprises have begun to attach importance to the assistance of computer information systems to manage the completion of various decision-making activities in operation. This paper designs an enterprise human resource decision support system based on data mining to more effectively support human resource management business information, data standardization, intelligent decision analysis, optimize human resource business processes, improve human resource management business efficiency, provide more effective decision support for enterprise operation and promote enterprise development. Results of the study show the effectiveness of the research.

Designer-Centric Spatial Design Support

Design-centric systems focus on searching or generating design alternatives using design retrieval or generation algorithms. Conversely, designer-centric systems focus on providing design feedback to refine design ideas through interactions with designers when creating design alternatives. This paper proposes a novel designer-centric design support system that analyzes user design moves and provides real-time feedback to augment the spatial design exploration process. Specifically, we developed a system that integrated sketching, design retrieval, and feedback features for tablet PCs. The user experiments involving 21 professional spatial designers verified that the proposed system helped users interact with their designs, navigate novel design spaces, reevaluate design moves, and embody design ideas. These findings provided implications for developing an interactive design exploration method for coordinating designers and computers, thereby extending design support system research. Further, we discuss applications and challenges in implementing the system on the web, revealing possibilities for data trailing of design moves.

Guest Editorial Special Issue on Radar and Microwave Sensor Systems

This Special Issue is devoted to technical papers on radar and sensor systems in microwave and millimeter-wave bands. Massive technological progress has been made in recent years at the microwave device and component level, enabling new research directions on sophisticated microwave and millimeter-wave systems. Among the most significant fields of application for such systems has been sensor technology, with a major emphasis on radar systems. Interest in automotive sensing, wireless human-computer interaction, biometric measurements, industrial monitoring, and target tracking—among many other applications—has driven this interest. Advances in device and component technology are supporting system design concepts that treat the microwave hardware as a co-design element of the system, along with signal processing and antenna design. Such co-design is of particular importance in radar and sensor systems, where a rapidly increasing number of wireless devices and an increasingly crowded spectrum necessitates the design and use of specialized signals (both temporal waveform designs and spatial beamforming) to maintain and improve sensor performance. Systems designed for general broad applicability are becoming more challenging to implement, while specialized systems that co-design the aperture, microwave hardware, and signal processing are becoming increasingly relevant. Technologies such as digital array radar, distributed and networked sensors, computational imagers, high-sensitivity Doppler radars, and integrated millimeter-wave radar, to name only a few, have supported system-level developments.

Distribution Law of In Situ Stress and Its Engineering Application in Rock Burst Control in Juye Mining Area

This paper presents an integrated approach for mathematical statistics, theoretical analysis, and a field test to investigate the distribution law of in-situ stress and its engineering practice of rock burst control. The test site is located in the Juye mining area, Shandong Province, China. The main conclusions included: (1) There are two types of in-situ stress states in the Juye mining area, σH > σV > σh (42.42%) and σH > σh > σV (57.57%), which are mainly caused by the tectonic stress of the Heze and Fushan faults (The σH, σV, and σh is the maximum principal stress, vertical principal stress or intermediate principal stress and minimum principal stress respectively). (2) The lateral pressure coefficients KH, Kh, and Kav show a non-linear distribution with increased depth, approaching 1.32, 0.96, and 1.41, respectively. The variation range of the horizontal difference stress μd is 0.09–0.58. (3) The average value of the stress gradient is 3.05 MPa/100 m, and the main directions of the maximum horizontal principal stress are northeast–southwest, and northwest–southeast. (4) A new combined supporting strategy, incorporating optimization of roadway layout, anti-impact support system design, and local reasonable pressure relief, was proposed for the rock burst control, and its validity was verified via field monitoring. All these design principles and support strategies for the rock burst control presented in this study can potentially be applied to other similar projects.

Design of decision-making support system in power grid dispatch control based on the forecasting of energy consumption

Electric grids are constantly expanding, and supervisory control and management methods must also be improved and changed in order to maintain reliable and safe power supply to consumers. This article proposes a methodology for supporting the adoption of dispatch decisions on the base electrical load forecasting. The energy consumption forecast is based on a deep neural network, and depending on the value obtained, a recommendation for optimising the operation of the energy system is proposed. Thus, dispatch service employees will be able to make decisions on managing the energy system based on the recommendations received, which will increase the speed of decision-making and improve the efficiency of the entire dispatch centre. Also, intelligent data processing and the proposed decisions allow us to consider and compare the factors that may be missed because of the human factor when the information is processed directly by the dispatcher. The use of retrospective data about the consumed power, the ambient temperature, and the type of day of the week is proposed as a knowledge base for forecasting energy consumption and training a neural network. The proposed neural network made it possible to achieve a value of the average absolute error of MAPE prediction of 1.922%. The obtained accuracy allows the use of forecasting results for dispatch control.

Understanding Clinician Macrocognition to Inform the Design of a Congenital Heart Disease Clinical Decision Support System.

Background and ObjectivesChildren with congenital heart disease (CHD) are at risk of deterioration in the face of common childhood illnesses, and their resuscitation and acute treatment requires guidance of CHD experts. Many children with CHD, however, present to their local emergency departments (ED) with gastrointestinal and respiratory symptoms that closely mimic symptoms of CHD related heart failure. This can lead to incorrect or delayed diagnosis and treatment where CHD expertise is limited. An understanding of the differences in cognitive decision-making processes between CHD experts and ED physicians can inform how best to support ED physicians when treating CHD patients.MethodsCardiac intensivists (CHD experts) and pediatric emergency department physicians (ED physicians) in a major academic cardiac center were interviewed using the critical decision method. Interview transcripts were coded deductively based on Schubert and Klein's macrocognitive frameworks and inductively to allow for new or modified characterization of dimensions.ResultsIn total, 6 CHD experts and 7 ED physicians were interviewed for this study. Although both CHD experts and ED physicians spent a lot of time sensemaking, their approaches to sensemaking differed. CHD experts reported readily recognizing the physiology of complex congenital heart disease and focused primarily on ruling out cardiac causes for the presenting illness. ED physicians reported a delay in attributing the signs and symptoms of the presenting illness to congenital heart disease, because these clinical findings were often non-specific, and thus explored different diagnoses. CHD experts moved quickly to treatment and more time anticipating potential problems and making specific contingency plans, while ED physicians spent more time gathering a range of data prior to arriving at a diagnosis. These findings were then applied to develop a prototype web-based decision support application for patients with CHD.ConclusionThere are differences in the cognitive processes used by CHD experts and ED physicians when managing CHD patients. An understanding of differences in the cognitive processes used by CHD experts and ED physicians can inform the development of potential interventions, such as clinical decision support systems and training pathways, to support decision making pertaining to the acute treatment of pediatric CHD patients.

An operational approach to ground control in deep mines

As mines go deeper and get larger, mine designs become more fragile largely due to the response of the rock mass to mining. Ground control and rock support become important levers in the mine construction schedule, production performance, and excavation health. For example, in cave mines, the production footprint together with associated mine infrastructure are significant investments in a modern caving operation. This investment must be protected and maintained to reduce the risk of ground-related production disruptions. It is necessary to preserve the health of these excavations and their maintenance through an effective rock support design. Rock support thus becomes a strategic element in asset management. This article focuses on support design for brittle ground when displacements induced by stress-fracturing consume much of the support's capacity. It deals with the functionality of the support in deforming ground. Several interlinked concepts are important when assessing excavation health. Designs must not only account for load equilibrium but also for deformation compatibility and capacity consumption. Most importantly, the support's displacement capacity is being consumed when the rock mass is deformed after support installation. Hence, it is necessary to design for the support capacity remaining at the time when the support is needed. If support capacity can be consumed, it can also be restored by means of preventive support maintenance (PSM). This concept for cost-effective ground control is introduced and illustrated on operational evidence. Furthermore, how design can impact construction costs and schedule are discussed. Support is installed to provide a safe environment and preserve an operationally functional excavation. It also must assure senior management that investments in high quality support and its maintenance will substantially reduce delays and with it, costs. It is demonstrated that the use of ‘gabion-like’ support systems can achieve these goals. A technical summary of the ‘gabion panel’ support system design is presented.

Physical model simulation of rock-support interaction for the tunnel in squeezing ground

The existence of squeezing ground conditions can lead to significant challenges in designing an adequate support system for tunnels. Numerous empirical, observational and analytical methods have been suggested over the years to design support systems in squeezing ground conditions, but all of them have some limitations. In this study, a novel experimental setup having physical model for simulating the tunnel boring machine (TBM) excavation and support installation process in squeezing clay-rich rocks is developed. The observations are made to understand better the interaction between the support and the squeezing ground. The physical model included a large true-triaxial cell, a miniature TBM, laboratory-prepared synthetic test specimen with properties similar to natural mudstone, and an instrumented cylindrical aluminum support system. Experiments were conducted at realistic in situ stress levels to study the time-dependent three-dimensional tunnel support convergence. The tunnel was excavated using the miniature TBM in the cubical rock specimen loaded in the true-triaxial cell, after which the support was installed. The confining stress was then increased in stages to values greater than the rock's unconfined compressive strength. A model for the time-dependent longitudinal displacement profile (LDP) for the supported tunnel was proposed using the tunnel convergence measurements at different times and stress levels. The LDP formulation was then compared with the unsupported model to calculate the squeezing amount carried by the support. The increase in thrust in the support was back-calculated from an analytical solution with the assumption of linear elastic support. Based on the test results and case studies, a recommendation to optimize the support requirement for tunnels in squeezing ground is proposed.

Ground motion characteristics and their cumulative impacts to burst risks in underground coal mines

Ground motions resulting from seismic waves are one of the main factors to trigger coal burst hazards in underground mines. Ground motion induced dynamic impacts may apply to the highly stressed coal/rock mass and initiate dynamic failure. Although ground motion analysis has been widely used in burst-prone hard rock mines for designing support systems, there are only few studies focusing on the understanding ground motion characteristics in coal mines and their relationship with the coal burst damage. Therefore, based on nine-months seismic monitoring in a case study coal mine, this paper conducted a thorough analysis on quantifying ground motions to roadways in both far-field and near-field zones and correlating strong ground motions to actual coal burst damage. The results showed that most far-field ground motions were insignificant, which were less likely to initiate coal burst damage. However, with the same energy levels and hypocentral distances, the seismic events in coal mines can produce higher far-field ground motions than those in hard rock mines. Compared with the far-field ground motions, the near-field ground motions had much higher intensities. The strong dynamic impacts induced by the near-field ground motions may trigger dynamic failure in coal or rock mass when it is already critically stressed. An index called the number of high ground motions (NHGM) was developed to link ground motions with burst risks in roadways. The roadway zone that had experienced a long history of intensive ground motions, indicated by a higher degree of NHGM, were more likely to expect coal bursts in the future.Article highlightsQuantify ground motions to roadways in both far-field and near-field zones in underground coal mines.Demonstrate the relationship between ground motion intensity and coal burst damage.Develop a method to forecast potential burst damage zones in roadways based on historical ground motions.

Design of a Handicraft Product Marketplace using a Web-Based Business to Consumer (B2C) Method

West Sumatra is famous for its embroidery. Usually embroidery is found on mukena, hijab, brackets, koko clothes, and others. The issue of marketing and brand promotion is still one of the biggest obstacles for embroidery businesses in increasing their business scale. Embroidery business actors often experience problems in selling their products. This cannot be separated from the tendency of these business actors to focus more on the production process without being balanced by marketing and promotion. Some embroiders, when the goods are available, they are confused about what to do to sell it quickly. As a result, the marketing and promotion steps taken tend to be conventional, namely word of mouth or simply displaying their products in stores. To overcome these problems, the authors conducted research to design a marketplace application to help business people to easily promote their products. In conducting this research the author uses the SDLC method. While the development of software in the design of this decision support system the author uses the PHP programming language. The results of this study are a marketplace application that can make it easier for customers to access products without having to come to the place, make purchases, transfer payments or online anywhere, so as to increase customer buying interest
