The book deals extensively with polynomial filters, namely, fixed-memory,expanding-memory and fading-memory filters.
Science Bulletins: Another Star Found in Big Dipper
A long-hidden star in the Big Dipper's handle has come to light thanks to a precision imaging technique by members of Project 1640, a collaboration between astronomers from the American Museum of Natural History, the University of Cambridge, the California Institute of Technology, and NASA. The team used a coronagraph to block out the blinding light from the star Alcor to resolve a faint companion in orbit around it, now named Alcor B. The team then imaged the same system 103 days later, mapping
Science Bulletins: Fog in Flux for California Redwoods
The Northern California coast is home to giant redwoods —the tallest trees in the world. The towering evergreens depend on the region's foggy climate, especially during the hot summer months. When rainfall is insufficient to hydrate the trees from the roots, the trees quench themselves by drawing moisture into their leaves from the fog.
Researchers at the University of California--Berkeley recently analyzed the frequency of coastal fog over the past hundred years. They discovered many fluctua
Science Bulletins: Will the Fish Return?
A series of immense banks—plateaus submerged in relatively shallow ocean waters—stretches from Newfoundland to southern New England. At the southwestern end of this chain lies Georges Bank, where vast numbers of fish feed and grow. Legend has it that the first European sailors found cod so abundant that they could be scooped out of the water in baskets.
Until the last decades of this century these banks were one of the world's richest fishing grounds—until overfishing on a massive scale b
Science Bulletins: China's Acidic Farmland
With 7 percent of the world's arable land but 20 percent of the world population, Chinese farmers have, for decades, relied upon artificial fertilizer to boost their crops. These artificial fertilizers, while increasing overall crop yields, can also upset the chemical balance in the soil and cause it to become more acidic. Recently, researchers compared samples of Chinese soil from the 1980's and the 2000's and found that agricultural lands across the country have become considerably more acidic
Safe Beaches (MWV62)
By: MicrobeWorld Staying safe at the beach involves more than just sunscreen and lifeguards. Beaches and oceans are prone to unhealthy levels of bacteria which can cause sickness in people. Pathogens make their way into the water and onto the sand from many sources, including but not limited to, animal and human waste, agricultural and sewer runoff. Knowing when and how to avoid harmful bacteria is an effective way to prevent getting sick when visiting the beach.
