Thrust ripple and density greatly impact the performance of linear machine other actuators, causing positioning control precision, dynamic performance, efficiency issues. Generalized pole-pair combinations are difficult to satisfy both thrust for double salient reluctance machines. In this paper, a DC-Biased vernier (DCB-VRLM) is proposed solve abovementioned The key design reduce enhance with ...

Introduction This series of meetings (Palazzo, 2002; Stearns & Winey, 1997) began as a joint ASCB/EMBO venture in 1997 with a meeting that was a landmark event, not only because a minor field had grown to fill an entire meeting, but also because key presentations defined the course of the field for years to come. The first biochemical mass spectrometric analysis of the budding yeast spindle pol...

It was the great geochemist Harold Urey who first called attention to peculiar conditions at the poles of the Moon. In his book The Planets: Their Origin and Development, Urey (1952) noted that the spin axis of the Moon was inclined only 1.5 degrees from the normal to the plane of the Moon’s path around the Sun. The consequence of this geometry is that topographic depressions near the poles, wh...

Rho GTPases control fundamental aspects of neutrophil chemotaxis: establishment of front and back and orientation toward the chemoattractant. Two reports in this issue show that activated Cdc42 at the leading edge helps orient the cell's axis in a signaling complex with G beta gamma, PAK1, and PIX alpha; while Rho, activated via G alpha 13, mediates formation of the uropod, which then interacts...

Abstract Incubation behaviour is essential for understanding the reproductive success in birds. For example, orientation of bird important reducing incubation costs associated with wind or sun, but on other hand can be modified by perceived risk predation. We studied body position incubating White Stork Ciconia ciconia eastern Poland using a small unmanned aerial vehicle (drone). The head and s...

Abstract Influencers are highly visible tastemakers who professionally publish content on social media platforms. In their work, influencers tasked with reconciling contradictory positioning—they both promoters of consumption, and marshals “authentic” sociality community. thus organize world in ways that enable them to justify moving between two poles commerciality authenticity. this article, w...

We use the behavioural approach to de®ne and characterize control-lable and uncontrollable poles and zeros of multidimensional (nD) linear systems. We show a strong relationship between controllable poles and zeros and properties of the transfer function matrix, and we give characterizations of uncontrollable poles and zeros, in particular demonstrating that these have an input decoupling prope...

Regular walking with or without Nordic poles is effective over time at reducing discomfort in individuals with chronic low back pain (LBP). Nordic pole use increases balance and stability, distributes weight through the arms and torso, and decreases loading of the spine and lower limbs. The purpose of this study was to determine if Nordic poles would reduce perceived acute discomfort while self...

with the continuous development of the industrialization process, the countries all over the world gradually appeared lack of agricultural labor force and aging phenomenon, which was especially prominent in developed countries. however the agricultural robot with high operating efficiency, high qualities of work will play an increasingly important role in future agricultural production. robot n...
