This paper shows the modeling and control of a single-phase full-bridge inverter with high-frequency transformer that may be used as part of a two-stage converter with transformerless DC-DC side or as a single-stage converter (simple DC-AC converter) for grid-connected PV applications. The inverter is modeled in order to obtain a small-signal transfer function used to design the P+Resonant current controller. A highfrequency step-up transformer results in reduced voltage switches and better efficiency compared with converters in which the transformer is used on the DC-DC side. Simulations and experimental results with a 200 W prototype are shown. 1

The fractal geometry of nature is seen in organizations and has set handcrafted artifacts, among them African Kente cloth traditionally produced by Ewe and Ashanti of West Africa. Incorporating parameters also classify products as carriers of fractal geometry, the Kente fabrics exhibit built from geometric shapes classified as seeds or unique architecture. This article aims to analyze examples of Kente cloths and establish the existence of geometric structures formed from a parent cell, exposing how this cell and how its architecture and formed patterns are maintained throughout the finished product.

This work presents the results of the efficiency of three protection methods of roads slopes, against the development of erosion processes.The methods anlyzed were: (1) grass planting "San Carlos" (Axonopus compressus), (2) litter, composed of remains of branches and leaves of eucalyptus E. Grandis, and (3) Compacted soil cover with a local soil with properties more resistant to erosion processes.The experiment consisted of assembly of four rectangular cells with 6 meters, three for protection systems in study and one was kept unprotected to evaluate the efficiency of the methods in study.The determination of the amount of eroded sediment was based on the sum of the solids in suspension and stored sediments in the geotextile bags.The results showed that, compared to the unprotected cell, the litter obtained a reduction of soil loss of 90%, while the grass enveloped and reduced 80% and 65% respectively.
