The Internet of Things (IoT, also Cloud of Things (CoT)) refers to the interconnection of uniquely identifiable embedded computing like devices with the existing Internet infrastructure.
Wearable computers, also known as body-borne computers or wearables are miniature electronic devices that are worn by the bearer under, with or on top of clothing. This class of wearable technology has been developed for general or special purpose information technologies and media development. Wearable computers are especially useful for applications that require more complex computational support than just hardware coded logics.
Televisions entered U.S. households in large numbers after World War II, and personal computers became widespread in business in the 1980s. With these technological innovations, leisure and then work time in the United States began to increasingly center on screen-based systems. Millions of people now spend workdays in front of computers and then retire to their houses to watch TV, play videogames or surf the web.
On September 19 BP’s Deepwater Horizon well was officially declared sealed after having poured nearly 5 million barrels of oil into the Gulf of Mexico. Coincidentally, the following day the National Bureau of Economic Research announced that the recession that started in late 2007 had ended in June. While these two crises are now ostensibly over, their effects are likely to be felt for years.
Hydropower accounts for two-thirds of all renewable electricity production in the United States. A 2008 paper by the University of Missouri at Saint Louis, “The Potential of Water Power in the Fight Against Global Warming,” discusses the potential for hydropower in reducing U.S. greenhouse gas emissions.
The rise of antimicrobial-resistant bacteria is among the greatest emerging public health problems. Resistance, acquired by bacteria through natural selection, has been accelerated by the improper use of antibiotics. Because such strains can be resistant to even newer, more powerful compounds, their infections are associated both with higher disease and death rates and with greater economic tolls on health care systems.
