Opis:
The availability of dynamic resource management will be crucial for the deployment of future wireless systems characterized by high data rate services with rigid quality of service demands. Flexible radios appear as the technological answer required to achieve constraint goals under different channel conditions and transmission scenarios. This paper is focused on enhancing another step of flexibility within the resource management by including an efficient handling of computing resources. This concept towards flexible architectures represents a key word for a real successful implementation due to the relationship between the radio applications, which face the scarcity of resources within a heterogeneous environment, and the processing power needed to execute them.

Opis:
In this work, the influence of both characteristics of the lens and misalignment of the incident beams on roughness measurement is presented. To investigate how the focal length and diameter affect the degree of correlation between the speckle patterns, a set of experiments with different lenses is performed. On the other hand, the roughness when the beams separated by an amount are non-coincident at the same point on the sample is measured. To conclude the study, the uncertainty of the method is calculated.

Opis:
Soil acidity is one of the factors affecting agricultural productivity worldwide, and it is corrected with materials from carbonates or hydroxides of Ca and Mg of different origins, including products from the cellulose industry such as ash + dregs (AD) and ash + dregs + sludge (ADS). Field experiments in a split plot design were conducted to evaluate the cellulose industry residues on chemical properties associated with soil acidity in three volcanic soils in Chile, cultivated with wheat in the 2019-2020 season. Treatments included a control without amendment, CaCO3 at an adjusted dose to achieve pH 6.0 (dose 1) and AD and ADS at dose 1 and double dose 1 (dose 2). Results indicated that AD and ADS in the three soils increased pH in the first 30 to 120 day after being applied, and achieved the same overall acidity correction effect at dose 1, with values that increased from pH 5.85 of control to 5.99 and 6.10, for dose 1 of AD and ADL respectively, at Santa Rosa location. In Carillanca location, the increase was from 5.52 of control to 6.27 and 6.24 for AD and ADL respectively, and in Remehue location – the soil reaction rose from pH 5.54 of Control to 5.91 and 5.89 for AD and ADL respectively (p<0.05). Using AD at dose 1 in the three soils had less effect on increased exchangeable Ca, but a greater effect on exchangeable Na and K concentrations. Using ADS at dose 1 showed a quantitatively lower effect on exchangeable Ca and higher exchangeable Mg and Na concentrations in soils. Results indicate that AD and ADS are an alternative to CaCO3.
