When you measure downtime in thousands of dollars per minute, reliability and good maintenance become practically priceless. Unfortunately, knowing this doesn't make it any easier to get inside a nuclear reactor's pressurized steam generators to inspect, clean, and maintain its pipes and tubes.
Chaos theory is now being studied aggressively. Simple practical control of the double pendulum is extremely promising for many control applications.
PID loops control a majority of the automated processes in industrial facilities. The proportional-integral-derivative (PID) algorithm is both simple and reliable, and has been applied to hundreds of thousands of control loops over the last 50 years.However, not all industrial processes can be controlled with PID loops.
Many professions involve some certification procedure whereby practitioners can demonstrate competency. For lawyers, it's the bar exam. For accountants, it's the CPA. For engineers, it's the P.E.—the Professional Engineer's license.A P.E. license entitles practitioners to advertise themselves as "engineers" and offer engineering services to the public.
Employees, managers, and companies face ever-increasing economic, business, job, and often personal pressures. This culture puts employees' work and personal lives at odds, but new evidence shows work and personal realms may be able to cooperate for mutual benefit.A recent study, "Holding a Job, Having a Life: Strategies for Change," demonstrates how some companies and employees are using impro...
