Constraints are part of identifying and defining a problem, the first stage of the engineering design cycle. Cast iron was stronger than stone and comparatively light. A lighthouse overlooking a 100-foot (30.48 meter) cliff, for example, wouldn't need to be built as tall as one positioned closer to sea level. The best way to use Service Health is to set up Service Health alerts to notify you by using your preferred communication channels when service issues, planned maintenance, or other changes might affect the Azure services and regions you use. /Pa6 << Bulls-eye Lens: A convex lens used to concentrate (refract) light. -taiga (boreal forest) In another category, occulting lights are normally on and momentarily extinguished, with short eclipses interrupting longer periods of light. To avoid misfires when you're trying to detect a lack of data in the logs, consider using metric alerts. Early lighthouses used whatever materials were available locally: wood, brick, stone, concrete, reinforced steel and cast iron. The same year, James Douglass used larger stones and a more precise design to build the lighthouse that stands today, 14 miles (22.5 kilometers) off the coast. Also called an eclipsing light. 6) Hold time violations: In cases where a signal crosses from a faster clock domain to a slower one, a pulse extender can be used to hold the signal to meet the capture time of the destination domain. A criterion is a standard or attribute of a design that can be measured. After first earning a second-rate reputation for the poor quality of its lighthouses, the United States became home to more than 1,000 lighthouses by 1900 [source: Ray].
