In order to observe interference using paired-associate stimuli, the target association should be similar, to some extent, to the interfering association, otherwise interference would not occur. For example, if subjects are asked to memorize word pairs (e.g., donkey-tree and dog-tree), interference will occur when two pairs share a common ...
Lashley suggested that brain interference patterns could play a role in perception, but was unsure how such patterns might be generated in the brain or how they would lead to brain function. [ 17 ] Several years later an article by neurophysiologist John Eccles described how a wave could be generated at the branching ends of pre-synaptic axons.
The top shows the directive pattern of a horn antenna, the bottom shows the omnidirectional pattern of a simple vertical dipole antenna. In the field of antenna design the term radiation pattern (or antenna pattern or far-field pattern) refers to the directional (angular) dependence of the strength of the radio waves from the antenna or other ...
The antennas contained in mobile phones, including smartphones, emit radiofrequency (RF) radiation (non-ionizing "radio waves" such as microwaves); the parts of the head or body nearest to the antenna can absorb this energy and convert it to heat or to synchronised molecular vibrations (the term 'heat', properly applies only to disordered molecular motion).
This is extremely useful when the antenna is at a very high point, and the edge of the signal is likely to miss the target (broadcast audience, cellphone users, etc.) entirely. With electrical tilting, front and back lobes tilt in the same direction. For example, an electrical downtilt will make both the front lobe and the back lobe tilt down.
The thinned-array curse (sometimes, sparse-array curse) is a theorem in electromagnetic theory of antennas.It states that a transmitting antenna which is synthesized from a coherent phased array of smaller antenna apertures that are spaced apart will have a smaller minimum beam spot size, but the amount of power that is beamed into this main lobe is reduced by an exactly proportional amount ...
The radio signals from the separate antennas overlapped in space, and the interference patterns between the individual signals was controlled to reinforce the signal in certain directions, and mute it in all others. The delays could be easily controlled electronically, allowing the beam to be steered very quickly without moving the antenna.
Output Interference occurs when the initial act of recalling specific information interferes with the retrieval of the original information. [28] An example scenario in which Output Interference might occur would be if one had created a list of items to purchase at a grocery store, but then, neglected to take the list when leaving home.
