The horizontal pavement marking is an important safety feature that must be visible both day and night. The night visibility is assessed by retroreflectivity and depends on the number of glass microspheres on the painting. Thus, knowing the quantity and distribution of microspheres in the horizontal marking are indicative of its quality. This paper proposes to use correlation-based granulometry with pre-processing by U-Net convolutional network for counting the number of microspheres present in digital images. We evaluate 10 images containing 1468 microspheres. The outcomes are promising, reaching an average hit rate of 0.9334. Keywords— road demarcation, correlation-based granulometry, U-Net, microsphere quantification.

This work presents an analog joint source-channel coding scheme as an alternative for machine-type communications that require low latency. We have implemented parametric and non-parametric coding for non-Gaussian sets of samples, collected by sensors of temperature and humidity. Since the parametric mappings are optimal only for Gaussian sources, the Box-Cox transformation was used in order to improve performance. Furthermore, we have employed non-parametric coding, which adapts more efficiently to the data sets, further improving performance at the cost of greater complexity. Keywords— Analog Joint Source-Channel Coding, NonGaussian Samples, Machine-Type Communications.

This paper discusses the use of two information theory measures: transfer entropy and direct transfer entropy, as an approach for detection of causality and connectivity between continuous variables in industrial processes (continuous systems). These measures are asymmetric and identify and quantify linear or non-linear directional relationships between two variables. To estimate these measures, we used estimators based on distances between neighbors. The results obtained from simulations demonstrate the applicability of the measurements and their estimations in order to identify the connectivity map of two systems: autoregressive model (which can be compared with the analytical results) and four water tanks (an industrial systems). Keywords— Transfer entropy, causality, continuous processes, industrial processes.
