Improving Open Channel Network Operation Using Gate Control Support Model Developed with ArcGIS Geoprosessing Tools
… improving the operation and management of open channel networks. Implementing simulation models and software is an effective step in achieving better operation of control structures in open channel networks. The purpose of this study was to develop a tool in ArcGIS for assisting the open channel …

Simulating high-throughput cryptocurrency payment channel networks
Payment channels secured with cryptocurrency as collateral enable users to make many transactions with few blockchain broadcasts. Networks of payment channels have emerged as a proposed solution to Bitcoin’s scaling problem. Since the proposal of the first payment channel network, the Lightning …

Modeling the Lafourche Delta network in the Mississippi Delta Complex
<p>The distributary channel network morphology on deltas is important for the delta evolution study because channels are the primary conduit for carrying and distributing water, sediment, and nutrients to the coast. Numerical models of river deltas and their channels have improved remarkably over …

Controls on post-High Park Fire channel response, South Fork Cache la Poudre Basin, Colorado
… The goal of this study was to evaluate how the channel network contributes to the production, transport, and storage of sediment by monitoring post-fire channel response. A better understanding of channel production, transport, and storage of sediment post-fire is required in order to predict …

Remote Sensing For An Improved Geospatial Flash Flood Susceptibility Modeling Over An Arid Environment
… GSPEs. Accurate digital terrain model (DTM) and channel network/orders with fine spatial details are mandatory for flood extent modeling. The DTM and its derived channel network have been employed successfully in many studies to extract various geomorphometric, topographic and hydrologic …

Biologically inspired transparent material as an energy system
… thisfunctionality by hierarchical multi micro-channel network scaling, as a leaf resistor. Resistor conduit analysis defines flow target resistance through simulation to generatea multi micro-channel network, for enhanced solar radiation absorption. This isdemonstrated by precise hydrodynamic …

Computational fluid dynamical studies of structured distillation packings
… plane The corrugations provide a regular network of channels for vapour liquid contact. Until recently it has been necessary to develop new packings by trial and error, testing new shapes in the laboratory. The orderly repetitive nature of the channel network produced by a structured …

Modeling Soil Erosion in the Upper Green River, KY
… the United States, contributing sediments to channels mainly as nonpoint pollution resulting from land-use and agricultural practices and leading to sedimentation downstream and downwind, a decrease in the transport capacity of streams, increase in the risk of flooding, filling reservoirs, and …

Management of intermediated channels for high technology firms : achieving success in a dynamic and rapidly changing marketplace
… the effective utilization of intermediated sales channels. As product development cycles shorten, there can be a scenario where the rate of product and solutions development and introduction to the market out-pace the manufacturer's ability to sell, service, and support the new products and …

Relative sea-level rise and the development of channel-fill and shallow-water sequences on Cape Cod, Massachusetts
Channel-fill sediments located in shallow-water off the south shore of Cape Cod, Massachusetts, provide a record of the late-Pleistocene and Holocene geological evolution in a post-glacial setting. Though conventionally difficult to sample adequately and anticipated to have low preservation …

Development of an Automated Method for Identification of Wet and Dry Channel Segments Using LiDAR Data and Fuzzy Logic Cluster Analysis
… to provide a useful data set for wet and dry channel classification. LiDAR intensity return data are, in essence, a numeric representation of the characteristic light reflectivity of the object being scanned; the more reflective the object is, the higher the intensity return will be. Intensity …

Geomorphic modeling and routing improvements for GIS-based watershed assessment in arid regions.
… hydrologic models for ephemeral stream networks declines significantly as watershed size increases. The second is that no single model is capable of simulating runoff, erosion, and geomorphic response in the channel network for multiple consecutive events. A diffusion-wave routing …

Comparison of Flow Dynamics and Bifurcation Angles in Tributary and Distributary Channel Networks
<p>The dynamics of channel mouth bifurcations on river deltas can be understood using theory developed in tributary channel networks. Bifurcations in groundwater-fed tributary networks have been shown to evolve dependent on diffusive ground water flow patterns</p> <p>directly adjacent to the …

Vascular Network Formation via 3D Printing and Cell-Based Approaches
… of tissue engineering. A lack of a perfusable channel network within a large and densely populated tissue engineered construct leads to necrotic core formation, preventing fabrication of functional tissues and organs. While many approaches have been reported for forming vascular networks, …
