- Abstract
-
Emerging diseases can have devastating consequences for wildlife and require a rapid response. A critical first step towards developing appropriate management is identifying the etiology of the disease, which can be difficult to determine, particularly early in emergence. Gathering and synthesizing existing information about potential disease causes, by leveraging expert knowledge or relevant existing studies, provides a principled approach to quickly inform decision-making and management efforts. Additionally, updating the current state of knowledge as more information becomes available over time can reduce scientific uncertainty and lead to substantial improvement in the decision-making process and the application of management actions that incorporate and adapt to newly acquired scientific understanding. Here we present a rapid prototyping method for quantifying belief weights for competing hypotheses about the etiology of disease using a combination of formal expert elicitation and Bayesian hierarchical modeling. We illustrate the application of this approach for investigating the etiology of stony coral tissue loss disease (SCTLD) and discuss the opportunities and challenges of this approach for addressing emergent diseases. Lastly, we detail how our work may apply to other pressing management or conservation problems that require quick responses. We found the rapid prototyping methods to be an efficient and rapid means to narrow down the number of potential hypotheses, synthesize current understanding, and help prioritize future studies and experiments. This approach is rapid by providing a snapshot assessment of the current state of knowledge. It can also be updated periodically (e.g., annually) to assess changes in belief weights over time as scientific understanding increases. Synthesis and applications: The rapid prototyping approaches demonstrated here can be used to combine knowledge from multiple experts and/or studies to help with fast decision-making needed for urgent conservation issues including emerging diseases and other management problems that require rapid responses. These approaches can also be used to adjust belief weights over time as studies and expert knowledge accumulate and can be a helpful tool for adapting management decisions. • We developed methods for rapidly assessing hypotheses about disease etiology. • Methods included formal expert elicitation and Bayesian hierarchical modeling. • We illustrate this approach for a recently emerged disease in coral reefs. • These methods are useful for fast decision-making for conservation issues. • These methods can help adapt management decisions over time as knowledge accumulates.

Phasor measurement, Application software, Computer software testing, and Computer software
- Abstract
-
This article presents a study on real-time testing of synchrophasor-based "wide-area monitoring system's applications (WAMS application)." Considering the growing demand of real-time testing of "wide-area monitoring, protection, and control (WAMPAC)" applications, a systematic real-time testing methodology is formulated and delineated in diagrams. The diagrams propose several stages through which an application needs to be assessed (sequentially) for its acceptance prior to implementation into a production system. However, only one stage is demonstrated in this article which comprises the use of a prototyping software toolchain and whose potential is assessed as sufficient for preliminary real-time testing (PRTT) of WAMS applications. The software toolchain is composed of two components: the MATLAB software for application prototyping and other open-source software that allows ingesting prerecorded phasor measurement unit (PMU) signals. With this software toolchain, a PRTT study is presented for two WAMS applications: "testing of the PMU/phasor data concentrator (PDC)" and "testing of wide-area forced oscillation (FO) monitoring application."

- Abstract
-
Soils containing high concentrations of metals were treated using a soil washing process. The hypothesis was that metals could be concentrated in a single or small number of fine fractions which could be removed and disposed of to treat the contaminated soil. Lead and zinc were shown to be distributed over the > 4000, 2000–4000, 600–2000, 180–600, 38–180, 38–23, and < 9 µm soil size fractions. The study demonstrated that only one of four of the composites tested, generated a metal-rich fraction as a result of washing and soil fractionation. Using a scaling approach, with a laboratory prototype, this study demonstrates that lead and zinc contamination across the site were not able to be concentrated into any size fraction. Further, the metals could not be concentrated to any commercially viable extent to enable the development of a remediation strategy. The approach illustrated how costs can be contained in developing full-scale remediation processes through using a staged process based on the principles of prototyping and scaling.

- Abstract
-
A recent trend in technological evolution has focused on innovative self‐powered device systems involving miniaturized energy harvesting systems termed "nanogenerators." Triboelectric nanogenerators (TENGs) have generated heaps of interest in the field of energy storage devices and sensors, owing to its tendency to harvest mechanical energy and impart power to battery‐less miniaturized devices for comprehensive applications. The combination of TENG with 3D printing (3DP) has provided impetus in fabricating a device with innovative design and functionalities with different working modes and mechanisms to culminate into excellent device output performances. Several studies have focused on the significant role of nanomaterials in TENG to achieve flexibility, workability, and enhanced electrical output. This review aims to explore the influence of carbon‐based nanomaterials in ameliorating the processability, performance, and printing characteristics of extrusion‐based 3D‐printed TENG. The unique structure dimensions and excellent thermal, electrical, and mechanical properties of carbon‐based nanomaterials tend to contribute in enhancing the triboelectric efficiency of TENG. The carbon nanomaterials assist in enhancing significant performance of rapid prototyping during material extrusion 3DP. This review provides an insight into the critical aspects to be analyzed in fabricating an extrusion‐based 3DP TENG and examines the role of carbon‐based nanomaterials in developing smart triboelectric materials for next‐generation energy harvesting technologies.

- Abstract
-
The present work develops a novel gorilla troops optimization algorithm (GTO) for optimal control of an autonomous microgrid. The proposed proportional‐integral controller parameters are properly designed by the GTO algorithm. It is based on the integral squared error to minimize the system objective function. The suggested islanded microgrid system operates with several decentralized, electronically interfaced energy resources and their local loads. The new optimal controller is applied to regulate its voltage at the different points of common coupling and its frequency despite the load variation. The performance of the new proposal is compared with the PI controller that was designed by a particle swarm optimization algorithm. It is observed that the microgrid functioning operation is improved even more by applying a GTO‐based than the other. The control strategy is thoroughly tested using a Matlab/Simulink simpower‐system environment under various microgrid operating situations. It is also implemented with OPAL 4510 real‐time hardware in the loop and a rapid control prototyping module. The different benchmark experiments serve to show the superiority of the new optimizer.

-
The advancement in triboelectric nanogenerator technology leads to numerous advantages in various fields, especially in biomedical and healthcare applications. Theoretical modeling and simulation of sensors is the initial step for an optimized cost‐effective real‐time sensor fabrication which reduces the wastage of materials and rapid prototyping, giving an expected sensor performance. Herein, a theoretical model of single‐electrode triboelectric nanogenerator is presented which finds its application in healthcare monitoring as a wearable flexible pulse sensor to measure the wrist pulse for disease diagnosis. The device optimization in terms of structure, material and output performance is done based on the said application. A brief study of the operating principle of the sensor along with the factors affecting the output is discussed in this work. The design is conceptually investigated considering the electrostatic shield effect from the contact electrode. The output performance variation concerning the plain and micro‐structured triboelectric surface is also determined in terms of open‐circuit voltage of ≈16.95 and ≈21.63 V, respectively, and also a short‐circuit charge of ≈181.81 and ≈196.57 pC, respectively. The superior output performance even for smaller wrist pulse displacement range can serve as a significant assistance for the rational plan of the device structure. [ABSTRACT FROM AUTHOR]

Carbon offsetting, Concrete construction, Product life cycle assessment, Reinforced concrete, and Rapid prototyping
- Abstract
-
3D Concrete Printing (3DCP) is a rapidly expanding area in the field of architecture, engineering, and construction, but very limited research has quantitatively investigated its environmental impact. The existing Life Cycle Assessment (LCA) studies on 3DCP lack clearly defined functional units of comparison, especially considering load-bearing structures. This paper investigates the potential environmental benefits of 3DCP over conventional concrete construction for structural beams based on a cradle-to-grave comparative LCA. Unlike existing studies, this paper employs a recarbonation model to account for the carbon offsetting from the use-stage of 3DP concrete, which shows significant results. The assessment includes three-beam designs, each analyzed for both prefabrication and on-site construction scenarios. While currently, 3DCP has a generally higher environmental impact due to the larger quantity of cement employed in the process, the reduction of material through infill optimization for printed beams is a promising design principle to positively offset the environmental impacts in the construction sector. The paper draws recommendations for future research on material- and recarbonation-efficient 3DCP design for load-bearing structures, as well as on material development, e.g. integration of larger aggregates and low-clinker cement.

- Abstract
-
A measurement and development platform for collecting water quality data (the WaterWatcher) was developed. The platform includes sensors to measure turbidity, total dissolved solids (TDS), and water temperature as variables that are often collected to assess water quality. The design is extensible for research and monitoring purposes, and all the design files are provided under open-source permissive licenses for further development. System design and operation are discussed for illustrative purposes. A block diagram indicates elements of mechanical, electrical, and software design for this system. The mechanical assembly used to house circuit boards and sensors is designed using 3D printing for rapid prototyping. The electronic circuit board acts as a carrier for an Arduino 32-bit microcontroller board and an associated cellular module along with a GPS for geolocation of water quality measurements. The cellular module permits data transfer for Internet of Things (IoT) functionality. System operation is set up using a command line interface (CLI) and C + + code that allows for calibration coefficients and human-readable transfer functions to be defined so that sensor voltages are related to physical quantities. Data are cached on a secure digital (SD) card for backup. The circuit was calibrated, and system operation assessed by deployment on an urban reservoir. Biogeochemical cycles were identified in the collected data using spectrogram and semivariogram analyses to validate system operation. As a system with hardware and software released under an open source license, the WaterWatcher platform reduces the time and effort required to build and deploy low-cost water quality measurement sensors and provides an example of the basic hardware design that can be used for measurements of water quality.

Abstract: Great interest currently exists for developing ecosystem models to forecast how ecosystem services may change under alternative land use and climate futures. Ecosystem services are diverse and include supporting services or functions (e.g., primary production, nutrient cycling), provisioning services (e.g., wildlife, groundwater), regulating services (e.g., water purification, floodwater retention), and even cultural services (e.g., ecotourism, cultural heritage). Hence, the knowledge base necessary to quantify ecosystem services is broad and derived from many diverse scientific disciplines. Building the required interdisciplinary models is especially challenging as modelers from different locations and times may develop the disciplinary models needed for ecosystem simulations, and these models must be identified and made accessible to the interdisciplinary simulation. Additional difficulties include inconsistent data structures, formats, and metadata required by geospatial models as well as limitations on computing, storage, and connectivity. Traditional standalone and closed network systems cannot fully support sharing and integrating interdisciplinary geospatial models from variant sources. To address this need, we developed an approach to openly share and access geospatial computational models using distributed Geographic Information System (GIS) techniques and open geospatial standards. We included a means to share computational models compliant with Open Geospatial Consortium (OGC) Web Processing Services (WPS) standard to ensure modelers have an efficient and simplified means to publish new models. To demonstrate our approach, we developed five disciplinary models that can be integrated and shared to simulate a few of the ecosystem services (e.g., water storage, waterfowl breeding) that are provided by wetlands in the Prairie Pothole Region (PPR) of North America.

This article is devoted to the laboratory technology aspects of high areal capacity electrode (more than 5 mAh cm−2) fabrication using carbon nanotubes (CNTs) as conductive additives and LiFePO4 as an active material. The influence of electrode slurry rheological properties and electrode composition on its areal (mAh cm−2), volumetric (mAh cm−3), and gravimetric (mAh g−1) capacity, and C‐rate performance has been studied. Using the small‐angle neutron scattering technique, it is shown that the CNT network embedded in the electrode layer provides greater wettability by an electrolyte compared with carbon black used as conductive additive. The practical applicability of the considered electrode technology is approved on a pouch cell prototype with a capacity of approximately 1.9 Ah and specific energy density of 150 Wh kg (cell)−1/295 Wh L (cell)−1.

The integration and quickness between the phases of product development process are key elements for companies' competitiveness and the prototyping technologies provide relevant means for the development of new products. The prototyping of products by additive manufacturing can vary in quality, costs, materials and characteristics, however, incorporating environmental and sustainable attributes are important strategies to support the design for manufacturing. This paper proposes method for multi-attribute evaluation of prototyping technology associated with sustainable product conception. This proposal focuses on improving the decision-making process and provide the prioritization of technical characteristics and it was evaluated and validated, through case studies, applying selective laser sintering and fused deposition modelling technologies into two prototype developments: a bristles protector (lightweight composite product) and a toothbrush (single massive product). The research innovates by proposing a matrix that allows the inclusion of environmental and sustainable features in the design decision-making process, promoting the integration of multiple perspectives that involves customer, product and technology associated with sustainable concepts meeting the current demand of the society and companies for the development of sustainable products.

3D printing of missing parts of a cultural heritage artifact opens many possibilities and extends the challenges in the processes of intervention on cultural heritage assets. However, restoring these objects may not only mean the replacement of a missing element from its esthetic point of view, but restoring the function for which objects were created. In these processes, the replica of the object must be exact and of quality, but also specific. In this sense, the presented work is a multi-disciplinary attempt to reproduce the missing horn of a phonograph dated to the late nineteenth century. This phonograph belongs to the collection of the 'Vicente Miralles Segarra' Telecommunication Museum of the Universitat Politècnica de València. The objective was to recover its esthetic, didactic, and functional levels, i.e restoring its ability to emit sound. To this end, several models were printed with different materials, and the quality of the recorded sound with the different horns was evaluated, assessing their similarity to that obtained from an original horn.

• Intuitive workflow for prototyping broad range of reservoir concepts for CCS. • Flow diagnostics approximate dynamic behaviour of CO2 on the fly. • Easy manipulation of injection wells through drag-and-drop. • Fast screening reservoir models prior to detailed CCS simulations. • RRM software available as open source. Sketch-based interface and modelling is an approach to reservoir modelling that allows rapid and intuitive creation of 3D reservoir models to test and evaluate geological concepts and hypotheses and thus explore the impact of geological uncertainty on reservoir behaviour. A key advantage of such modelling is the quick creation and quantitative evaluation of reservoir model prototypes. Flow diagnostics capture key aspects of reservoir flow behaviour under simplified physical conditions that enable the rapid solution of the governing equations, and are essential for such quantitative evaluation. In this paper, we demonstrate a novel and highly efficient implementation of a flow diagnostics framework, illustrated with applications to geological storage of CO 2. Our implementation permits 'on-the-fly' estimation of the key reservoir properties that control CO 2 migration and storage during the active injection period when viscous forces dominate. The results substantially improve the efficiency of traditional reservoir modelling and simulation workflows by highlighting key reservoir uncertainties that need to be evaluated in subsequent full-physics reservoir simulations that account for the complex interplay of viscous, gravity, and capillary forces. The methods are implemented in the open-source Rapid Reservoir Modelling software, which includes a simple to use graphical user interface with no steep learning curve. We present proof-of-concept studies of the new flow diagnostics implementation to investigate the CO 2 storage potential of sketched 3D models of shallow marine sandstone tongues and deep water slope channels.

- Abstract
-
The purpose of this paper is to re-explore the relationship between utopia and architecture, trying first and foremost to challenge the way utopia has been conceived by architectural thought: i.e., as the prefiguration of a future seen as an ‘otherness’ distinct from the present, as far as the totality of its spatial, social, and political dimensions are concerned. Such vision – as we will argue – turns out to be deeply linked to a design logic of ‘projection’ and ‘prescription’; this, however, is not the only possible logic of design. Through a reflection upon some contemporary architectural practices, we will try to highlight a new horizon for design action, in which even utopia abandons its traditional ‘projective’ role and takes on a new meaning: rather than being the non-place of a possible future, utopia stands for what doesn’t have place in the present but can emerge from its alteration. Such notion of utopia as a form of ‘situated critique’, in a concrete space and time, helps to dig more deeply into the political potential of many contemporary forms of architectural and urban design.
Il proposito di questo contributo è tornare a esplorare la relazione tra utopia e architettura, cercando innanzitutto di mettere in questione il modo in cui l’utopia è stata concepita tradizionalmente nel pensiero architettonico: vale a dire, come la prefigurazione di un futuro concepito come alterità rispetto al presente, nella totalità delle sue dimensioni spaziali, sociali e politiche. Tale visione - come si cercherà di illustrare - è intimamente legata a una certa logica “proiettiva” e “prescrittiva” che, tuttavia, non è l’unica logica possibile del progetto. Attraverso una riflessione su alcuni modi del progetto di architettura contemporaneo, si cercherà infatti di mettere in evidenza una nuova logica progettuale, in cui anche l’utopia abbandona il suo carattere proiettivo tradizionale per acquisire un nuovo senso: non più il non-luogo di un futuro possibile, bensì ciò che non ha luogo nel presente e che può tuttavia emergere dalla sua alterazione. Questa nozione di utopia come “critica situata” concretamente in uno spazio e in un tempo aiuta a comprendere più in profondità il potenziale politico di molte delle forme contemporanee di progetto architettonico e urbano.
