Such studies, however, can be applied only to the relatively narrow range of chemical compounds for which FF parameterizations exist.
State-of-the-art classical force fields (FFs) allow to study the structure and dynamics of systems that include billions of atoms 1. Many problems in computational chemistry and materials science require large-scale simulations at atomic resolution. The presented methodology is fast, accurate, and highly automated, which allows its application in diverse areas of materials science. We illustrate the capabilities of our methodology to simulate functional materials in several case studies: chemical degradation of material in organic light-emitting diode (OLED), polymer chain packing, material morphology of organometallic photoresists. The accuracy of the QMDFF is verified by comparison with the experimental properties of liquid solvents. We present a computational approach for atomistic simulations of complex molecular systems, which include the treatment of chemical reactions with the empirical valence bond approach. The problem can be solved using a quantum mechanically derived force field (QMDFF)-a system-specific force field derived directly from the first-principles calculations. Such simulations are often problematic for conventional classical force fields, which require tedious and time-consuming parameterization of interaction parameters.
I recall that around 1954 up.the shiny metallic paint schemes for bikes was very popular.The computational design of functional materials relies heavily on large-scale atomistic simulations. Red ) This is just speculation may not be correct at all, but for now, thats as close as I can tell for what years my Schwinn was built until, as GTs58 stated, we can get documentation, if that is possible. Why would Schwinn care what day a frame was built The SN in not a VIN number with detailed build info like model, components etc.
Schwinn stingray serial numbers starting with kc serial number#
Schwinn Occ Stingray S Serial Numbers Were Stampedīut later down the road when new production methods were introduced the serial numbers were stamped by bench mounted automatic stamping machines.Īt that time the numbers were stamped on the frame component prior to it being used to build a frame.Ī serial number is just that, and the recorded date doesnt even indicate a frame build date, just the date the serial number was recorded and possibly stamped on the dropout, headtube or even the bottom bracket. Im just trying to find out why everyone believes this falsehood because its spreading like the smell from a dairy farm. There are other sites that also follow in this dumbness telling the uninformed newbie that the serial gives you the build date. Please fill me in with some hard facts that can prove the serial number with its recorded date is somehow the build date of a bike. So were does everyone get the wild idea that the serial number is related to any build date The serial number was used for future identification purposes and that was the only intended purpose of that number. In 1976 Schwinn started stamping the actual build date on the head badges and not one has matched the recorded date of a serial number. Schwinn Occ Stingray S Serial Numbers Were StampedĪ serial number is just a serial number and it has absolutely nothing to do with any build date.
