Banana quality attribute prediction and ripeness classification using support vector machine

Five laser diodes of 532, 660, 785, 830 and 1060nm laser light back scattering imaging (LLBI) were employed for quality attribute prediction and ripening stage classification of banana. A support vector machine (SVM) was tested to establish the theoretical prediction and classification models to predict chlorophyll, elasticity and soluble solids content (SSC) and also to classify the bananas into six ripening stages. The classification was set up with six ripening stages 2-7. Wavelengths of 532, 660 and 785nm gave high correlation coefficients both for banana quality prediction and ripeness classification. The results show that the highest correlation coefficients of 0 .912, 0.945 and 0.872 were obtained for chlorophyll, elasticity and SSC at 785, 660nm respectively. An overall classification accuracy of 92.5% was recorded at 830nm. These results show that LLBI with the SVM model can be used for non-destructive estimation of banana quality attributes and the subsequent ripeness classification

Coulomb fragmentation and Coulomb fission of relativistic heavy-ions and related nuclear structure aspects

The Coulomb excitation of 208Pb projectiles has been studied at an energy of 640 A MeV. Cross sections for the excitation of the two-phonon giant dipole resonance were measured for different targets, and show clear evidence for a two-step electromagnetic excitation mechanism. The experimental cross sections exceed those calculated in the harmonic oscillator approximation by a factor of 1.33 ± 0.16. The deduced 27-decay probability is consistent with the expectation in the harmonic limit. Finally, the excitation of the two-phonon giant dipole resonance in the deformed and fissile nucleus 238U is discussed

Wissenschaftliche Grundlagen der Endlagersicherheit in der Nachbetriebsphase eines Endlagers fuer hochradioaktive Abfallstoffe in einem Salzstock Ergebnisse zum Rahmenplan 'Endlagersicherheit in der Nachbetriebsphase' 1989-1992

The framework plan gives an account of the current status and further, still necessary research and development work for the elaboration of scientific fundamentals and for the development of methods for the safety analysis of a future Federal radwaste repository for heat-releasing radioactive waste in salt formations. The framework plan is subdivided into a review of results and a part with project descriptions. The review of results covers the four subject areas: Scenarios and programs, chemical effects in the close-in area, geotechnical and physical effects in the close-in area, transport processes in the geosphere. (orig./HP)Der Rahmenplan gibt einen Ueberblick ueber den derzeitigen Stand und die Notwendigkeiten noch zusaetzlicher Arbeiten zur Erarbeitung wissenschaftlicher Grundlagen sowie zur Methodenentwicklung fuer die Sicherheitsanalyse eines zukuenftigen Bundesendlagers fuer waermeerzeugende radioaktive Abfaelle in Salzformationen. Es ist in einen Ergebnisteil und einen Teil mit Vorhabensbeschreibungen gegliedert. Der Ergebnisteil umfasst hierbei die vier Themenbereiche: Szenarien und Programme, chemische Effekte im Nahbereich, geotechnische und physikalische Effekte im Nahbereich sowie Transportvorgaenge in der Geosphaere.
