This paper investigates the capacity behavior in an aeronautical MIMO link between a terrestrial transmitting station and an airborne station. The channel model is small-area and considers only the scattering function. For this purpose, two different scenarios are simulated and analyzed. In the first one, only reflected scattered paths are considered and(More)
The plasma concentration of human lipoprotein[a], Lp[a], is highly correlated with coronary artery disease. The protein moiety of Lp[a], apoLp[a], consists of two apoproteins, apo[a] and apoB-100, linked by one or more disulfide bonds(s). Apo[a], the protein unique to Lp[a], exists in polymorphic forms that exhibit different apparent molecular weights (Mr).(More)
This article presents a new method to estimate the intensity of a human facial expression. Supposing an expression occurring on a face has been recognized among the six universal emotions (joy, disgust, surprise, sadness, anger, fear), the estimation of the expression’s intensity is based on the determination of the degree of geometrical deformations of(More)
The understanding of an image deals with the consideration of the most banal information conveyed by each pattern. A crucial anchor for facial expression analysis is to consider not only permanent features but transient ones too. In this work we are interested by all the outcomes of transient features in the analysis of facial expressions. Three processes(More)
An intrinsic problem of classifiers based on machine learning (ML) methods is that their learning time grows as the size and complexity of the training dataset increases. For this reason, it is important to have efficient computational methods and algorithms that can be applied on large datasets, such that it is still possible to complete the machine(More)
The present paper proposes a system both able to classify a facial expression in one of the six universal categories namely: (Joy, Disgust, Anger, Sadness, Fear and Surprise) and to assign to each expression its intensity in the range: (High, Medium and Low). This is carried out in two independent and parallel processes. Permanent and transient facial(More)
