The mode switching of PSR B2020+28

Mode Switching and Subpulse Drifting in PSR B 0826 − 34

We present high-quality observations of PSR B0826−34 at 1374 MHz. The emission from this pulsar exhibits strong bursts of pulses followed by long periods of ‘null’ pulses. When it is strong, the radiation extends through the whole pulse period. We show for the first time that there is weak emission during the ‘null’ phases, which should therefore be considered to be a different mode rather than...

Mode Switching

In many control applications, a speciic set of output tracking controllers of satisfactory performance have already been designed and must be used. When such a collection of control modes is available, an important problem is to be able to accomplish a variety of high level tasks by appropriately switching between the low-level control modes. In this paper, we deene a concept of control modes, ...

the effect analysis of proficiency on language - switching in iranian efl learners writing

abstract in a protocol analysis of second language writing from 20 adult english as a foreign language (efl) iranian students, this research observed how language-switching (l-s), i.e., first language use in l2 writing, was affected by l2 proficiency. switching interactively between first (l1) and second (l2) languages has been recognized as one of the salient characteristics of l2 writing....

Protection Switching ( APS ) Mode

AND ASTROPHYSICS Null-induced mode changes in PSR B0809+74

We have found that there are two distinct emission modes in PSR B0809+74. Beside its normal and most common mode, the pulsar emits in a significantly different quasi-stable mode after most or possibly all nulls, occasionally for over 100 pulses. In this mode the pulsar is brighter, the subpulse separation is less, the subpulses drift more slowly and the pulse window is shifted towards earlier l...
