The challenge of revealing and tailoring the dynamics of radio-frequency plasmas

The complex dynamics of ionization and excitation mechanisms in capacitively coupled radio-frequency plasmas is discussed for single- and dual-frequency operations in low-pressure and atmospheric pressure plasmas. Electrons are energized through the dynamics of electric fields in the vicinity of the plasma boundary sheaths. Distinctly different power dissipation mechanisms can either co-exist or initiate mode transitions exhibiting characteristic spatio-temporal ionization structures. Phase resolved optical emission spectroscopy, in combination with adequate modelling of the population dynamics of excited states, and numerical simulations reveal dissipation associated with sheath expansion, sheath collapse, transient electron avalanches and wave–particle interactions. In dual-frequency systems the relative phase between the two frequency components provides additional strategies to tailor the plasma dynamics.

Estratégia de operações: reposicionando a ferramentaria da General Motors do Brasil

Trata do reposicionamento empresarial de um fornecedor interno de componentes vitais de veículos automotivos, onde existem divergências entre as maiores montadoras do mundo quanto a sua posição estratégica. A partir de um cenário global e da identificação do mapa de competências do processo atual, o objetivo é elaborar algumas alternativas estratégicas e/ou táticas para o reposicionamento que permita atender as novas necessidades competitivas
