This study investigated the effectiveness of individual and collaborative outputbasedfocus-on-form instructional tasks on the acquisition of English inversionstructures by EFL learners. Moreover, it explored the developmental trend oflearners’ inversion acquisition. To this end, 60 homogeneous EFL learners wereassigned to individual and collaborative output groups. They were exposed to textsenc...

At very high aggregate bandwidths, output queueing is impractical because of insufficient memory bandwidth. This problem is getting worse: memory bandwidth is improving slowly, whereas the demand for network bandwidth continues to grow exponentially. The difficulty is that outputqueued switches require memories that run at a speedup of N, where N is equal to the number of switch ports. This pap...

Separate types of frequency transducers, for example, string tensometers or induction tachometers, were known for many years ago. So, for example, patents for string distant thermometer (Pat. No.61727, USSR, Davydenkov N., Yakutovich M.) and string distant tensometer (Pat. No. 21525, USSR, Golovachov D., Davydenkov N., Yakutovich M.) were obtained in 1930 and 1931 accordingly. However, the outp...

A global robust output feedback dynamic compensator is proposed for stabilization and tracking of a class of systems that are globally di eomorphic into systems which are in generalized output-feedback canonical form. This form includes as special cases the standard outputfeedback canonical form and various other forms considered previously in the literature. Output-dependent nonlinearities are...

Consider a network whose inputs change rapidly, or are subject to frequent faults. This is expected often to be the case in the foreseen huge sensor networks. Suppose, that an algorithm is required to output the majority value of the inputs. To address such networks, it is desirable to be able to stabilize the output fast, and to give guarantees on the outputs even before stabilization, even if...
