  • laboratory

    a laboratory uk: / l ə ˈ b ɒr ə t ər i /, us: / ˈ l æ b ər ə t ɔːr i /; colloquially lab is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. laboratory services are provided in a variety of settings: physicians offices, clinics, hospitals, and regional and national referral centers.

  • rotational–vibrational spectroscopy

    rotational–vibrational spectroscopy is a branch of molecular spectroscopy concerned with infrared and raman spectra of molecules in the gas phase.transitions involving changes in both vibrational and rotational states can be abbreviated as rovibrational or ro-vibrational transitions.when such transitions emit or absorb photons electromagnetic radiation , the frequency is proportional to .

  • vibration

    vibration testing is accomplished by introducing a forcing function into a structure, usually with some type of shaker. alternately, a dut device under test is attached to the 'table' of a shaker. vibration testing is performed to examine the response of a device under test dut to a defined vibration environment.

  • magnetic stirrer

    a magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar or flea immersed in a liquid to spin very quickly, thus stirring it. the rotating field may be created either by a rotating magnet or a set of stationary electromagnets, placed beneath the vessel with the liquid.

  • molecular vibration

    a molecular vibration is a periodic motion of the atoms of a molecule relative to each other, such that the center of mass of the molecule remains unchanged. the typical vibrational frequencies, range from less than 10 13 hz to approximately 10 14 hz, corresponding to wavenumbers of approximately 300 to 3000 cm −1 .

  • national center for research on earthquake engineering .

    national center for research on earthquake engineering ncree; chinese: 國家地震工程研究中心 is an organisation found in taipei, taiwan.since taiwan is located on the ridge of the eurasian and philippine tectonic plates, it is highly seismic.the biggest earthquake in taiwan in more than a century was 21 september 1999, also known as the chi-chi earthquake which measured 7.3 on the .

  • shakers

    the united society of believers in christ's second appearing, more commonly known as the shakers, is a millenarian nontrinitarian restorationist christian sect founded circa 1747 in england and then organized in the united states in the 1780s. they were initially known as 'shaking quakers ' because of their ecstatic behavior during worship .

  • network for earthquake engineering simulation

    the george e. brown, jr. network for earthquake engineering simulation nees was created by the national science foundation nsf to improve infrastructure design and construction practices to prevent or minimize damage during an earthquake or tsunami. its headquarters were at purdue university in west lafayette, indiana as part of cooperative agreement cmmi-0927178, and it ran from 2009 .

  • laboratory

    the earliest laboratory according to the present evidence is a home laboratory of pythagoras of samos, the well-known greek philosopher and scientist. this laboratory was created when pythagoras conducted an experiment about tones of sound and vibration of string.

  • simulation table

    a simulation table is an automotive test system specifically designed for the high-frequency testing of vehicle components. it is sometimes also called a multi-axis shaker table or mast.. they can simulate acceleration and displacement outputs and reproduce key data collected on proving grounds, by providing a full six degrees of freedom 6 dof .

  • earthquake shaking table

    there are several different experimental techniques that can be used to test the response of structures and soil or rock slopes to verify their seismic performance, one of which is the use of an earthquake shaking table a shaking table, or simply shake table . this is a device for shaking scaled slopes, structural models or building .

  • du noüy–padday method

    the padday technique also offers low operator variance and does not need an anti-vibration table. this advantage over other devices allows the padday devices to be used in the field easily. the rod when made of composite material is also less likely to bend and therefore cheaper than the more costly platinum rod offered in the du noüy method.

  • vortex mixer

    the vortex mixer was invented by brothers jack a. and harold d. kraft while working for scientific industries a laboratory equipment manufacturer . a patent was filed by the kraft brothers on april 6, 1959 and granted on october 30, 1962. scientific industries still makes a version of this original vortex mixer.
