Buck Boost

Fallows dresses his argument with a call for higher personal standards among journalists, who are urged to follow politicians by making transparent their financial and other interests, to re-build trust with a public which increasingly regards them as ‘buck rakers’ rather than muck-rakers. Many themes intertwine in this ‘public journalism’ debate: some concern issues of media ownership and journalistic ethics dealt with later in this book. But when we place side by side our snapshots of…

Também é necessário utilizar este conversor quando se deseja uma tensão CC de saída de valor diferente daquele fornecido pelas baterias e painéis. Pode-se utilizar este conversor tanto para elevar a tensão (conversores tipo Boost) quanto para abaixar a tensão (conversores tipo Buck). Também é possível obter com este conversor várias tensões de saída a partir de uma única tensão de entrada. A eficiência dos conversores depende dos semicondutores de potência utilizados e de alguns outros…

com tensões em torno de 3 VDC e a corrente máxima total não ultrapassa 100 mA. Nessa faixa de operação, as fontes chaveadas oferecem uma relação muito boa entre custo, rendimento e tamanho. A versão usada neste trabalho é baseada na configuração Buck com realimentação direta, em que um oscilador de freqüência central de 66 kHz controla um transistor MOS-FET chaveando a carga por um tempo de condução que varia conforme a demanda de corrente, mantendo a tensão de saída constante. Ele…

Here are a couple of tips to keep in mind: Large retail chain stores, also known as big box retailers, spend millions of dollars every year on demographic studies on where to build their next stores. Wal-Mart and Home…

Unless you decide to spend $2,995 for “The Last Hole” (a casket with golf scenes) or “Memories of the 68 The Ku Klux Klan and Real-Estate Agents Hunt” (featuring big-racked bucks and other prey) or one of the much cheaper models that the funeral director somehow failed even to mention. The Internet, powerful as it is, has hardly slain the beast that is information asymmetry. Consider the so-called corporate…

Truman said, ¬ The buck stops here. HTML5 disallows this: “A person’s name is not the title of a work— even if people call that person a piece of work— and the element must therefore not be used to mark up people’s names.” This is bonkers.

150-year-old financial services group that we’ll call European Financial Services (EFS) is one of the companies that adopted this process to develop a strategy that breaks away from the competition. The resulting EFS strategy yielded a 30 percent revenue boost in its initial year. The process, which builds on the six paths of creating blue oceans and involves a lot of visual stimulation in order to unlock people’s creativity, has four major steps (see figure 4-1). Step 1: Visual…
