This book presents a tutorial review of van der Pol model, a universal oscillator model for the analysis of modern RC−oscillators in weak and strong nonlinear regimes. A detailed analysis of the injection locking in van der Pol oscillators is also presented. The relation between the van der Pol parameters and several circuit implementations in CMOS nanotechnology is given, showing that this theory is very useful in the optimization of oscillator key parameters, such as: frequency, amplitude and phase relationship. The authors discuss three different examples: active coupling RC−oscillators, capacitive coupling RC−oscillators, and two-integrator oscillator working in the sinusoidal regi...

Carcara Photo Art's Brazilian Photography collection presents Jurandy Valença. In his own words: “I create images, I don’t create photographs. My production comes from everyday references. The main issue in my work is time. The memory.”
Chronicling the dramatic history of the Brazilian Amazon during the Second World War, Seth Garfield provides fresh perspectives on contemporary environmental debates. His multifaceted analysis explains how the Amazon became the object of geopolitical rivalries, state planning, media coverage, popular fascination, and social conflict. In need of rubber, a vital war material, the United States spent millions of dollars to revive the Amazon's rubber trade. In the name of development and national security, Brazilian officials implemented public programs to engineer the hinterland's transformation. Migrants from Brazil's drought-stricken Northeast flocked to the Amazon in search of work. In defense of traditional ways of life, longtime Amazon residents sought to temper outside intervention. Garfield's environmental history offers an integrated analysis of the struggles among distinct social groups over resources and power in the Amazon, as well as the repercussions of those wartime conflicts in the decades to come.
