Five classifiers including the K-means, Fuzzy c-means, K-nearest neighbour, Multi-Layer Perceptron Neural Network and Probabilistic Neural Network classifiers are compared for application to colour grade classification and detection of bruising of Granny Smith apples. A number of suitable discriminate features are determined heuristically for the categorisation of four classes including: high g...

The temperature dependence of the exciton dynamics in a conjugated polymer is studied using time-resolved spectroscopy. Photoluminescence decays were measured in heterostructured samples containing a sharp polymer-fullerene interface, which acts as an exciton quenching wall. Using a 1D diffusion model, the exciton diffusion length and diffusion coefficient were extracted in the temperature rang...

A membrane-bound, monovalent cation-stimulated ATPase from Zea mays roots has been purified to a single band on sodium dodecyl sulfate gel electrophoresis. Microsomal preparations with K(+) -stimulated ATPase activity were extracted with 1 m NaClO(4), and the solubilized enzyme was purified by chromatography on columns of n-hexyl-Sepharose, DEAE-cellulose, and Sephadex G-100 Superfine. A 500-fo...

In this paper, some clustering techniques are analyzed to compare their ability to detect botnet traffic by selecting features that distinguish connections belonging to or not belonging to a botnet. By considering the history of network’s connections, some clustering algorithms are used to derive a set of rules to decide which should be considered as a botnet. Our main contribution is to evalua...

Individual turbinals from the right and left sides of dog olfactory tissue were removed and nerve-ending-particle preparations were prepared. (Na+ + K+)-dependent ATPase activities of the individual preparations, and the effect of several odorous compounds [including (+)and (-)-carvonel on the (Na+ + K+)-dependent ATPase activities, were determined. The maximally stimulatory odorant concentrati...

The stiffness of the hadronic equation of state has been extracted from the production rate of K+ mesons in heavy-ion collisions around 1 AGeV incident energy. The data are best described with a compression modulus K around 200 MeV, a value which is usually called "soft." This is concluded from a detailed comparison of the results of transport theories with the experimental data using two diffe...

We analyze the partial rate asymmetry in B ± → P ¯ P π ± decays (P = π + , K + , π 0 , η) which results from the interference of the nonresonant decay amplitude and the resonant amplitude for B ± → χc0π ± followed by the decay χc0 → P ¯ P. The CP violating phase γ can be extracted from the measured asymmetry. We find that the partial rate asymmetry for B ± → π + π − π ± is 0.33 sinγ, while for ...

We revisit the recently proposed method for the determination of the ππ scattering length combination a0 − a2, based on the study of the π0π0 spectrum in K+ → π+π0π0 . In view of a precision measurement, we discuss here the effects due to smaller absorptive contributions to the K+ → π+π0π0 and K+ → π+π+π− amplitudes. We outline a method of analysis that can lead to a precision determination of ...
