Antenna is also said to be an impedance transforming device. 2. What is meant by radiation pattern? Radiation pattern is the relative distribution of radiated power as a function of distance in space .It is a graph which shows the variation in actual field strength of the EM wave at all points which are at equal distance from the

Stoneley-wave attenuation and velocity are sensitive to fracture and formation permeability‚ especially at low frequencies. Stoneley-wave velocity declines‚ and its attenuation increments‚ as permeability increments. Beginning endeavors (started in the 1970s) to get permeability information from Stoneley information was unsuccessful because neither the significant low-frequency instruments nor the proper handling techniques had been created. The parallel advancement of present day multi-pole array

Constructive waves deposit eroded material along the shore‚ which eventually builds up over time to form a beach. This occurs when the swash is stronger than the backwash‚ depositing more sediment than it transports elsewhere. Although beaches are a landform of deposition‚ they can also be considered to be a landform of erosion. When waves are huge and high‚ the backwash is more powerful than the swash‚ removing more loose material than it deposits. These types of waves are known as destructive waves. The

D6T thermal sensor and People Counting Algorithm In this thesis work‚ a new indoor people counting algorithm is created by using Omron D-6T thermal sensor and Raspberry Pi. The sensor periodically generate thermal map of heat emitted in its field of view which is a one dimension array and pass the array to Raspberry for further processing. The people counting algorithm is created in Raspberry Pi by processing thermal map generated by D6T. After processing the number of people indoor is obtained
