Flow rate control in standing column wells: A flexible solution for reducing the energy use and peak power demand of the built environment
No full textStanding column wells offer a generous and flexible solution to improve the energy efficiency of the built environment. As these systems behavior is strongly affected by groundwater advection, the acute challenge of predicting their thermal evolution with both accuracy and computational efficiency has so far hindered the development of design tools and optimized control strategies. In this work, a powerful simulation algorithm is implemented and applied to the performance assessment of multi-borehole standing column well systems located in a heterogeneous geological environment and operating under various constant and dynamic flow rate control strategies. The iterative algorithm relies on the non-stationary convolution technique to simulate the underground components, and the EnergyPlus approach to represent the heat pump efficiency at full and part loads. The findings suggest that using higher flow rates in peak conditions is a key element that minimizes auxiliary assistance and power demand. Complementary variable flow rate control aiming to maintain a 2 °C temperature difference across the plate heat exchanger has shown to alleviate groundwater usage and generate at least 8%–11% annual energy savings compared with constant flow. This operating strategy allowed the systems to deliver 197–246 W/m with a heating seasonal performance factor of 3.59. These results were achieved through 34 annual simulations having hourly time steps that were performed with the proposed algorithm in a total of 4 h 17 min, compared to 11 days for a single simulation using a numerical reference model

No full textRescue and Recovery in the Space Age (Search, Rescue and Recovery)
No full textThis paper will be presented by Colonel Emil G. Beaudry, Vice Commander, Aerospace Rescue and Recovery Service. It will include a statement of the present Aerospace Rescue and Recovery Service mission and how it relates specifically to our country\u27s various space programs, past, present, and as far into the future as we can project.
It will cover the introduction of the HC-130\u27s into the Aerospace Rescue and Recovery Service inventory, the Fulton System and its potential, the possibilities of air-to-air recovery and the entirely new concepts of air-to-air refueling of the HH-3 helicopter from the HC-130H aircraft and rnid-air recovery of aerospace hardware and personnel. It will conclude with an investigation of our need for rescue in space as a logical extension of the historic ARRS humanitarian approach to people in distress within the sensible atmosphere. Each of the general areas will be investigated in depth
Generalized symmetries in singularity-free nonlinear models and their disordered phases
No full textWe study the nonlinear -model in -dimensional spacetime with connected target space and show that, at energy scales below singular field configurations (such as vortices), it has an emergent non-invertible higher symmetry. The symmetry defects of the emergent symmetry are described by the -representations of a discrete -group (i.e. the emergent symmetry is the dual of the invertible -group symmetry). The -group is determined such that its classifying space is given by the -th Postnikov stage of . In D and for finite , this symmetry is always holo-equivalent to an invertible -form (ordinary) symmetry with potential \u27t Hooft anomaly. The singularity-free disordered phase of the nonlinear -model spontaneously breaks this symmetry, and when is finite, it is described by the deconfined phase of higher gauge theory. We consider examples of such disordered phases. We focus on a singularity-free nonlinear -model in D and show that it has an emergent non-invertible higher symmetry. As a result, its disordered phase is described by axion electrodynamics and has two gapless modes corresponding to a photon and a massless axion. Notably, this non-perturbative result is different from the results obtained using the and nonlinear -models in the large- limit.13+12 pages, 1+2 figures. v2: published versio

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
