The first stage, which incorporates the feedstock or fuel production and processing and fuel delivery or energy transmission, and is called the "upstream" stage, while the stage that deals with vehicle operation itself is sometimes called the "downstream" stage. The well-to-wheel analysis is commonly used to assess total energy consumption, or ...
This mechanism for producing consistent product quality & reducing waste presents a good case for utilising continuous manufacturing technologies. The control of a steady state process when you understand the upstream & downstream effects is an easier task as common cause variability is easier to define and monitor.
Life cycle engineering is defined in the CIRP Encyclopedia of Production Engineering as: "the engineering activities which include the application of technological and scientific principles to manufacturing products with the goal of protecting the environment, conserving resources, encouraging economic progress, keeping in mind social concerns, and the need for sustainability, while optimizing ...
The HEC-RAS model calculated that the water backs up to a height of 9.21 meters at the upstream side of the sluice gate, which is the same as the manually calculated value. Normal depth was achieved at approximately 1,700 meters upstream of the gate. HEC-RAS modeled the hydraulic jump to occur 18 meters downstream of the sluice gate.
On the other hand, Exxon Mobil projects that variations in industry margins will impact energy products earnings by $(0.7) b Goldman Sachs Flags Weak Q4 Guidance For Exxon Amid Weak Upstream And ...
Analysis of temperature profiles from 11 large dams in the Murray Darling Basin (Australia) indicated differences between surface water and bottom water temperatures up to 16.7 degrees Celsius. [24] If this water is released to maintain river flow, it can cause adverse impacts on the downstream ecosystem including fish populations. [25]
Vertical integration is the degree to which a firm owns its upstream suppliers and its downstream buyers. The differences depend on where the firm is placed in the order of the supply chain. There are three varieties of vertical integration: backward (upstream) vertical integration, forward (downstream) vertical integration, and balanced (both ...
The documentation data include information about the analyst, the project, and the analysis. The site and region data include the highway-site characteristics, the ecoregions, the upstream-basin characteristics, and, if a lake analysis is selected, the lake-basin characteristics. The hydrologic data include precipitation, streamflow, and runoff ...
