This paper describes the performance of pianar back-to-back Barrier-N-N+ (bbBNN) devices for mmand submm wave multiplier applications. A technique has been deveioped for characterizing pianar bbBNN devices with Vector Network Anaiyzer, which gives both the series resistance and voitage dependent capacitance of the device. Resuits show that bbBNN devices do not have a high series resistance iike...

Michele Zorzi, Member, IEEE, and Ramesh R. Rao, Senior Member, IEEE Abstract— In this paper, an ARQ Go-Back-N protocol with unreliable feedback and time-out mechanism is studied, using renewal theory. Transmissions on both the forward and the reverse channels are assumed to experience Markovian errors. The exact throughput of the protocol is evaluated, and simulation results, that confirm the a...

the objective of this work was to determine the effect of sex, breed and birth season of calves on intensity of mllt (musculus longissimus lumborum et thoracis) area changes and development of the selected body parts in bulls and heifers of blonde d´aquitaine (ba) cattle during rearing period. two generations of bulls (n=63) and heifers (n=68) of blonde d´aquitaine (n=61) and crossbreds c×ba (c...

This letter presents a simple method to simultaneously optimize a multiplicity of design parameters for the adaptive automatic repeat request strategy previously reported, and subsequently provides a quantitative measurement that reflects the appropriateness of the selected parameters. An exact analytical expression that allows us to compute the throughput crossover probability between the two ...

The working memory construct refers to the capacity to maintain information for a limited time. Objectives To devise stimuli and adapt the 5-back test and to verify the effect of age in normal Brazilian individuals. Methods 31 healthy adults (15 young adults and 16 older adults) were evaluated by batteries of auditory stimuli to verify the inter-group differences (age effect) in working mem...
