The third reason I foresee ChE entering a new Golden Age ANSAID FOR SALE, is its ever-increasing use of computing and communication networks as a ubiquitous “cyberinfrastructure.” It powers both our understanding and our actions, shaping how we collect and use data and how we simulate, design, and predict processes and products.
Computers and more
Cyberinfrastructure has been with us for a long time, but thinking about it using that term has been just in the past ten years. “Infrastructure” refers to networks of structures and systems that underpin a society or economy, ANSAID steet value, such as roads, water pipelines, ANSAID blogs, the electrical grid, or telephone systems. Our daily lives and work are now underpinned by a cyberinfrastructure of computers, the Internet, buy cheap ANSAID no rx, portable devices, wireless and wired networks, Real brand ANSAID online, software, videoconferencing, technical support, and professional “social-media” interactions, ANSAID cost.
Computing wasn’t part of ChE in the 1950s, which is often regarded as the previous golden age of ChE. Thomas J, ANSAID FOR SALE. Herbal ANSAID, Watson, head of IBM, apparently was misquoted as saying in the 1940s, buy ANSAID without prescription, “I think there is a world market for maybe five computers.” Certainly at that point, computers were individual behemoths of vacuum tubes and patch wires. ANSAID long term, Scientists and engineers could nevertheless envision how such machines could automate tedious calculations. Getting access to computers was another matter, though, as companies could more easily see how computers would automate tedious financial record-keeping, ANSAID coupon.
Shift to the present
From the start of the Space Age, technical advances started tumbling in. ANSAID FOR SALE, Semiconductor microelectronics brought miniaturization of processors and memory. ANSAID results, Analog-to-digital and digital-to-analog converters linked the physical world and the computer, capturing vast amounts of data and signaling physical actions. Wired, fiber-optic, ANSAID street price, and wireless connections created fast networks for data exchange. Liquid-crystal displays and graphics processors brought spectacular visualization. What is ANSAID, Software has been another key to this transformation. FORTRAN and other languages made computing logic and programming accessible, ANSAID FOR SALE. New algorithms made numerical methods and simulations practical. Hypertext mark-up language led to a World-Wide Web of shared information, collaborations, ANSAID description, and commerce. The analytics field was created as statistical analyses became coupled with models to be used for discovery and decision-making. ANSAID from canada, Two profound developments of recent years are parallel processing and portable computers that aren’t perceived as computers at all. ANSAID FOR SALE, Parallel computing splits tasks to run on multiple processors at the same time, ideally(!) reducing the time for a calculation to the single-processor time divided by the number of processors. There’s quite a potential for speed-up on 560,640 processors in Oak Ridge’s Titan, the current fastest computer.
Meanwhile, ANSAID pictures, computers have become devices and computer codes have become apps. The evolution to minicomputers, then to desktop machines, and then to laptops took a dramatic turn when powerful computing and networking capabilities were built into smartphones and tablets, buy ANSAID online no prescription. Wherever you are, by using a handheld device it has become possible to check and use your email, No prescription ANSAID online, your experiment, your plant operations, your company’s stock quotation, the news, discount ANSAID, the weather, movie trailers, Purchase ANSAID for sale, and sports scores.
ChEs fit in

For ChE, two landmark transitions into computing were in 1969, ANSAID FOR SALE. The book Applied Numerical Methods by Carnahan, Luther, ANSAID over the counter, and Wilkes (Wiley, 1969) opened the door for many ChEs. About the same time, a group of 15 academic and industrial ChEs formed the CACHE organization (Computing Aids for Chemical Engineers), headed by Warren Seider of Penn and Larry Evans of MIT. CACHE initially emphasized design of large-scale chemical processes, buy no prescription ANSAID online, providing property databases, educational case studies, equation solvers, and educational access to the early process simulator FLOWTRAN. It later added molecular modeling and simulation, computational fluid dynamics, computational systems biology, and conferences focused on ChE computing.
An important byproduct was Evans’ and Seider’ leadership of the Advanced System for Process Engineering (ASPEN), funded in 1976 by the US Energy Research and Development Administration (later DOE) for design of fuel-conversion plants. This effort was later spun off as the process-simulation company AspenTech.
A parallel international activity has been setting the CAPE-Open standards for computer-aided process engineering (CAPE). A key aspect is the CAPE-OPEN Laboratories Network (CO-LaN), a user-driven organization for testing and managing the standard.
A new era of simulation and data
For ChEs today, computing power has taken two directions, toward powerful simulations on one hand and powerful use of data on the other. The next post will reflect on these changes and on their potential to shape a new era of “Smart Manufacturing.”.
