Abstract:
The channel attention mechanism is widely used in deep learning. However, the existing channel attention mechanism directly performs the global average pooling and then full connection for all channels, which causes the local information to be ignored and the feature information cannot be reasonably assigned with the proper weights. This paper proposed a local channel attention module, based on the channel attention. This module focuses on the local information of the feature image, obtains the weight of each regional channel through convolution, and then integrates the information, so that th

Abstract:
From the Chezy-Manning equation, considered valid for the "steady state" of a natural channel, as an extension of the condition of "uniform flow," it is interesting to determine the degree of variation of the average flow velocity, depending on the variations of the factors involved. That is why this article presents a theoretical analysis which yields a first approximation of the sensitivity of the variation of the magnitude of the average speed to changes in the geometry or geomorphology of a section of the channel. It is found that the concept of "stable state" for the thermodynamic state o

Abstract The heat transfer performances of the trapezoidal channel with the impinging row jets normal to the channel apex wall with no effusion and three effusion conditions from one, two and three rows of bleeding holes along the channel apex, or, and, channel sidewalls were studied. At each effusion condition, the airflow extraction from the channel tip were regulated as full open conditions, and 0% (full close), 5%, 10% of the total airflow rate fed into the trapezoidal channel via the impinging row jets. For each effusion and discharge condition, the full-field heat transfer data over the

Abstract:
This paper presents an analytical investigation of constant property, steady, fully-developed, laminar thermal transport in a parallel-plate channel comprised of metal superhydrophobic walls. The superhydrophobic walls considered here exhibit micro-ribs and cavities aligned in the streamwise direction. The cavities are assumed to be non-wetting and contain air, such that the Cassie-Baxter state is the interfacial state considered. The scenario considered is that of constant heat flux through the rib surfaces with negligible thermal transport through the air cavity interface. Closed form soluti

Abstract:
Abstract Pressure transient data can be costly to obtain and may not be available for many wells, while well production data is routinely collected and is even available from industry data bases. In the absence of pressure transient data, methods that can use readily available well production data to perform pressure transient analysis have been developed. However, most of these methods assume either constant rate or constant pressure producing conditions. Those methods that do attempt to handle variable rate and/or draw-down pressure data, do so in an approximate manner, usually by defining a

Abstract:
Matrix cooling systems are relatively unknown among gas turbines manufacturers of the western world. In comparison to conventional turbulated serpentines or pin-fin geometries, a lattice-matrix structure can potentially provide higher heat transfer enhancement levels with similar overall pressure losses. This experimental investigation provides heat transfer distribution and pressure drop of four different lattice-matrix geometries with crossing angle of 45 deg between ribs. The four geometries are characterized by two different values of rib height which span from a possible application in th

Despite the many differences among Caribbean nations, Climate Change (CC) poses a serious threat to them all. Average temperatures in the Region have increased by 0.1° to 0.2°C per decade over the past three decades and rainfall patterns have shifted, with the number of consecutive dry days expected to increase. Additionally, sea level rise has occurred at a rate of about two to four cm per decade over the past 33 years, a trend which presents risks to the Region's freshwater resources and to its largely coastal population dependent on tourism and agriculture.OVE's regional study aims to asses

Abstract:
Amid the rising climate change concerns, California enacted Senate Bill 375 (SB 375) to tackle transportation greenhouse gas (GHG) emissions. SB 375 requires Metropolitan Planning Organizations (MPOs) to develop a Sustainable Communities Strategy (SCS), a regional transportation and land use vision plan, to reduce GHG emissions. Meanwhile, a local government can develop a Climate Action Plan (CAP), a non-binding, voluntary plan to reduce GHG emissions that may align with the regional SCS. Recent progress reports indicate California is not making sufficient progress to meet SB 375 emissions red

These extents were compared with previously completed databases from 1896, 1913, 1971, 1994, 2009, and 2015. In addition to the glacial features mapped at the Park, any snow patches noted in satellite- and fixed-wing- acquired aerial images in September 2021 were mapped as perennial snowfields. In 2021, Mount Rainier National Park contained a total of 28 named glaciers which

Abstract:
The Forestry and Agriculture Sector Optimization Model with Greenhouse Gases (FASOMGHG) has historically relied on regional average costs of land conversion to simulate land use change across cropland, pasture, rangeland, and forestry. This assumption limits the accuracy of the land conversion estimates by not recognizing spatial heterogeneity in land quality and conversion costs. Using data from Nielsen et al. (2014), we obtained the afforestation cost per county, then estimated nonparametric regional marginal cost functions for land converting land to forestry. These afforestation costs were

The average performance in 2016 was driven by the weak economic performance of the commodity-producing countries while tourism-dependent countries benefited from lower oil prices and strong tourism demand.

The Arctic region is warming almost four times as fast as the global average. Snow and ice are thawing at an increasing rate, and the rapid environmental shifts have a disproportionate effect on communities across the Northern Hemisphere. This leads to significant permafrost degradation, which disrupts community infrastructure, cultural heritage, landscapes, and impacts animal migration and subsistence activities. This change has severe consequences for the youth in the region, affecting their present lives and future outlooks. This working paper emphasizes the importance of addressing these i
