Impact when robots act wisely

For stabilization of a robot manipulator upon collision with a stiff environment, a nonlinear hang-hang impact controller is developed. Under this control, a robot can successfully achieve contact t a s b without changing control algorithm or controller gains throughout all three modes: free space, transition and constrained motion. It uses a robust hybrid impedanceltime-delay control algorithm...

Impact, not impact factor.

When the English philosopher Herbert Spencer introduced the phrase “survival of the fittest” in 1864, he could not have imagined that it would summarize the plight of young scientists years later (1). As competition for coveted faculty appointments and research funding continues to intensify, today’s researchers face relentless pressure to publish in scientific journals with high impact factors...

Emerging alternatives to the impact factor

This paper offers an overview of the history of the impact factor as a measure for scholarly merit; a summary of frequent criticisms of the impact factor's calculation and usage; and a framework for understanding some of the leading alternatives to the impact factor.

NLO corrections to the photon impact factor

We review the program of the calculation of next-to-leading order corrections to the virtual photon impact factor. Following a brief introduction we present some technical aspects for the various contributions. Recently obtained results for transversely polarised virtual photons are discussed and an outline of how infrared divergences are cancelled is given. Implications of the subtraction of l...
