<p>Project coordination is recognized as one of the most important aspects that should be integrated effectively in project management to guarantee project success. In fact, coordination provides organization the ability to integrate heterogeneous activities for achieving specific targets. In project, when teams are built according to cross-functional approach, coordination is required to enhance communication between all project stakeholders. This article is in search of the relationship between specific project coordination mechanisms, adopted by marketing managers to integrate other functional activities, and project communication efficiency. Methodologically, our research was based on a quantitative questionnaire distributed to 107 functional managers involved in cross-funtional project team in Moroccan SMEs. An appropriate statistical analysis was deployed to examine data collected. Findings show the existence of a positive correlation between project coordination mechanisms and project communication efficiency. Besides, the importance given to marketing managers’ participation in project meetings was found as a factor impacting the amount of time devoted to. Therefore some insights are emphasized to develop research in this field.</p>

Mean Time

The current methods of calculating the economic productivity of fire pumpers reduce the value of the vehicle based on its lifetime use. However, it is reasonable to base the service time of a fire pumper on its original function. In this study, we proposed the use of the functional approach to determine the productivity of fire pumpers as opposed to the use of the economic approach. The Korea Fire Institute is a professional institution that inspected 342 fire pumpers in 2019. In all, 102 pumpers were found to be malfunctioning. The number was modified to 100 cases considering the production date and results of statistical analysis. Next, we determined a mean time to failure (MTTF) of 7.65 years based on the service time data using Weibull distribution; this MTTF is 2.35 years shorter than the current mean service time of the pumpers, so this study selected a reasonable service time of 8 years for a pumper.

If we make a set of measurements, such as narrow-band or multicolour photo-electric measurements, which are designed to improve a scheme of classification, and in particular if they are designed to extend the number of dimensions of classification, i.e. the number of classification parameters, then some important problems of analytical procedure arise. First, it is important not to reproduce the errors of the classification scheme which we are trying to improve. Second, when trying to extend the number of dimensions of classification we have little or nothing with which to test the validity of the new parameters.Problems similar to these have occurred in other areas of scientific research (notably psychology and education) and the branch of Statistics called Multivariate Analysis has been developed to deal with them. The techniques of this subject are largely unknown to astronomers, but, if carefully applied, they should at the very least ensure that the astronomer gets the maximum amount of information out of his data and does not waste his time looking for information which is not there. More optimistically, these techniques are potentially capable of indicating the number of classification parameters necessary and giving specific formulas for computing them, as well as pinpointing those particular measurements which are most crucial for determining the classification parameters.

Spectrum Imaging

As interest for parallel EELS spectrum imaging grows in laboratories equipped with commercial spectrometers, different approaches were used in recent years by a few research groups in the development of the technique of spectrum imaging as reported in the literature. Either by controlling, with a personal computer both the microsope and the spectrometer or using more powerful workstations interfaced to conventional multichannel analysers with commercially available programs to control the microscope and the spectrometer, spectrum images can now be obtained. Work on the limits of the technique, in terms of the quantitative performance was reported, however, by the present author where a systematic study of artifacts detection limits, statistical errors as a function of desired spatial resolution and range of chemical elements to be studied in a map was carried out The aim of the present paper is to show an application of quantitative parallel EELS spectrum imaging where statistical analysis is performed at each pixel and interpretation is carried out using criteria established from the statistical analysis and variations in composition are analyzed with the help of information retreived from t/γ maps so that artifacts are avoided.
