Coordination


An s orbital is spherically symmetrical and can contain a maximum of two electrons with opposed spins. A p orbital has a solid figure-of-eight shape there are three equivalent p orbitals for each principal quantum number they correspond to the three axes of rectangular coordinates.  [c.152]

The acentric factor is also dependent on the critical coordinates being used.  [c.114]

Table 5.22 indicates the test references to be conducted on engines according to procedures established by the Coordinating European Council (CEC). Note that these are long-duration tests, some lasting dozens or even hundreds of hours and they are costly.  [c.243]

GFC (Groupement Francois de Coordination pour le developpement des essais de performances des lubrifiants et des combustibles pour moteurs) the membership of which includes petroleum companies, additive manufacturers, automobile manufacturers and a few consumers. The GFC is interested mainly in mechanical testing.  [c.295]

In Europe, the CEC (Coordinating European Council for the development of performance tests for lubricants and engine fuels) federalizes the GEC and its counterparts in other European countries.  [c.295]

Therefore investigations using tomography were made. Some results of the tomography images are shown in fig. 11. The characteristic values given by analysing the tomography results were the defect volume and the placement coordinates of the defect inside the casting part.  [c.15]

The X coordinate (coordinate along the transducer alignment) of the sources that have overcome the screening test is calculated.  [c.69]

Finally, the concentrated localized AE events are represented on the monitor in the form of a histogram "number of localized AE events vs axial coordinate", which is automatically updated at user-defined time intervals.  [c.69]

Data presentation, histogram of the localized AE events vs axial coordinate along the transducer alignment. The histogram is superimposed on the simplified sketch of the monitored component (an example is given in Jig. 5), trend vs time of 8 plant parameters and/or AE parameters (signal RMS for each AE channel number of localized AE events for each transducer triplet an example is given in Jig. 6),  [c.70]

The copolymers of ethylene and propylene (OCVP) are obtained by coordination catalysis using a derivative of vanadium and a derivative of an aluminum alkyl. Molar compositions of ethylene and propylene are usually on the order 45 and 55%.  [c.356]

The actual configuration of the system can simultaneously manage up to 12 conventional piezoelectric transducers, with innovative signal acquisition and conditioning modules, simplified AE processing procedures and correlation of AE with plant operating parameters. AEBIL uses a binary time correlation procedure to perfonn on-line detection and localization of AE sources. AE source localization requirements are limited to the axial coordinate, in the case of elongated components (e g. steam headers, steamline sections). This trade-off enables the system to effectively cover one or more full-size components (or critical areas thereof) with a relatively small number of transducers and, at the same time, to ensure real-time source location and screening. The amount of diagnostically significant data to be stored, transferred and examined turns out to be limited.  [c.68]

Off-line analysis of stored data review of the stored data, organize data in different presentation windows, plot AE and plant parameters data so as to enable comparison and coirelation with the possibility to present data (histogram of AE events vs position, plant parameters and/or AE parameters vs time) conditioned in terms of time interval (initial time, final time) and/or position interval (defined portion of the component = initial coordinate, final coordinate) and/or plant parameters intervals (one or more plant parameters = initial value, final value).  [c.70]

The "SIMON" Project ("On-line acoustic monitoring of structural integrity of critical power plant components operating at high temperatures") had a duration of 4 years (1.10.1993 -30.09.1997) the Project Consortium included CISE (Project Coordinator, I), MITSUI BABCOCK ENERGY (UK), HERIOT-WATT UNIVERSITY (IK), PROET / EDP (P) and ENEL (I).  [c.71]

AEBIL is specifically designed to carry out on-stream detection and localization of spatially concentrated AE sources in the presence of a high background noise and a high rate of spatially scattered AE sources, typical condition found in operating plant environment. The actual configuration of the system can simultaneously manage up to 12 transducers. A binary time coirelation procedure performs on-line detection and localization of AE sources. Localization requirements are limited to the axial coordinate, since steam headers and steamline sections have an essentially linear geometry. These simplified signal processing procedures enable the monitoring system to effectively cover one or more full-size components (or critical areas thereof) with a small number of transducers, to achieve real-time operation and to limit the amount of data to be processed, locally stored and transmitted to a modem-connected remote monitoring station.  [c.76]

A new one-dimensional mierowave imaging approaeh based on suecessive reeonstruetion of dielectrie interfaees is described. The reconstruction is obtained using the complex reflection coefficient data collected over some standard waveguide band. The problem is considered in terms of the optical path length to ensure better convergence of the iterative procedure. Then, the reverse coordinate transformation to the final profile is applied. The method is valid for highly contrasted discontinuous profiles and shows low sensitivity to the practical measurement error. Some numerical examples are presented.  [c.127]

The V[GRAL software package, incorporated as a special feature within the ScanMaster environment of the upi-SO ultrasonic instrument, generates the V-scan image of the reflecting surface of a defect from B-scan data. The VIGRAL algorithm operates off-line in two stages first it evaluates each B-scan row to evaluate the ToF for each measurement point, then it calculates the source positions from inter-row data. This calculation includes sequential evaluation of the virtual sources and their segregation into individual sources, as described above. The resulting set of virtual source coordinates fbmis the V-scan image of the reflecting surface of the defect. This distribution is displayed in graphical form to size and locate the defect, and in the form of a histogram of source densities.  [c.167]
