Working Mechanism and Components of GPS
Each of the 24 satellites emits signals to receivers that determine their location or range by computing the difference between the time that a signal is sent and the time it is received.
Lifetime Prediction of Steel Penstocks
Predicting the lifetime of materials and components in engineering environments is the subject of this discussion. The method of prediction proposed here is based on two approaches: namely, The Corrosion Based Design Approach (CBDA) The Locations for Analysis Matrix (LAM). These methodologies are described in detail in other references.
Methods of Transportation of Concrete
Transporting the concrete mix is defined as the transferring of concrete from the mixing plant to the construction site. The main objective in transporting concrete is to ensure that the water-cement ratio, slump or consistency, air content, and homogeneity are not modified from their intended states. Concrete produced from a mixer is required to be transported to the
Global Hydrological Processes and Role of Water Cycle in Hydro Balance
Water evaporates from the ocean surface, driven by energy from the Sun, and joins the atmosphere, moving inland as clouds. Once inland, atmospheric conditions act to condense and precipitate water onto the land surface, where, driven by gravitational forces, it returns to the ocean through river and streams.
