  • Electrical consumption, especially direct or variable frequency currents, has strongly increased over 50 years in industry. This situation explains the growth of power electronics. At the beginning, when rectifiers replaced DC machines, only diodes and thyristors were used. Then power transistors appeared and enabled the extension of smaller power applications for domestic use. New research topics were developed around converters and power devices.

  • In ladder logic there are multiple types of outputs, but these are not consistently available on all PLCs. Some of the outputs will be externally connected to devices outside the PLC, but it is also possible to use internal memory locations in the PLC. Six types of outputs are shown in Figure 2.12. The first is a normal output, when energized the output will turn on, and energize an output. The circle with a diagonal line through is a normally on output. When energized the output will turn off. This type of output is not available on all PLC types....

  • Until relatively recent times, most periods of technological development have been linked to changes in the use of materials (eg the stone, bronze and iron ages). In more recent years the driving force for technological change in many respects has shifted towards information technology. This is amply illustrated by the way the humble microprocessor has built intelligence into everyday domestic appliances.

  • The art of compliance is a craft much like that of a carpenter who learns to work with various kinds of wood and designs. Ours is an industry wrought with differences. While the regulations that govern FDA-regulated industries are proscribed, how the regulations are interpreted and applied really depends on experience and how well one has mastered the craft of compliance. There are no proscribed procedures, but there are guideposts common to all FDA-regulated industries, whether a firm manufactures medical devices, pharmaceuticals, or biological products....

  • Structural changes had happened previously in U.S. history without such radical effects on cities, though they had certainly devastated some groups of workers. For example, the carriage industry in Michigan was totally replaced by automobile manufacturing, but there was little to offset the loss of automobile production in Flint. What, in fact, might replace the lost sectors and employment in these cases? Two answers suggested them- selves: services and high technology.

  • The study of the workshops in Jepara involved an initial extensive survey so as to locate all the workshops. Then we designed a spatial grid to prepare the following intensive survey. It consisted of sampling these workshops, creating a detailed database on the structure of the wood industry in Jepara, and subsequently analysing it (Roda and Cadène 2005). The fieldwork was conduced by a team of 12 surveyors4 and 2 field coordinators5 . They were equipped with motorbikes, global positioning system (GPS) devices, questionnaires, and computers.

  • As seen in Table 7, both Planned Parenthood and other WHP clinics typically offer a comprehensive range of contraceptive methods. The methods include oral contraceptives (the Pill) as well as long-acting reversible contraceptives (LARCs) such as intrauterine devices (IUDs), implants (e.g., Implanon), or injectables (e.g., Depo-Provera). LARCs are particularly important because they are the most effective in preventing unintended pregnancies and have lower failure rates.

  • New cars are supplied by auto manufacturers via a network of legally separate but captive retail dealerships. Whether the increased demand for high-fuel eciency cars and decreased demand for low fuel-eciency cars will show up primarily in the prices or in the market shares of new cars depends on the elasticity of the combined response in this supply chain. There are several reasons to think that supply may not be perfectly inelastic, and that therefore at least part of the response will show up in quantities.
