2. PATH ERRORS IN SUGARCANE TRANSSHIPMENT TRAILERS
ABSTRACT The need for accuracy in sugarcane machine traffic has boosted the adoption of automatic steering systems. These have been used in tractors pulling transhipment trailers. Such sets are long and articulated, which hinders their performance and benefits due to alignments in curved and laterally sloped paths. In this sense, this study aimed to quantify

4. Desenvolvimentos mecânicos e computacionais de suporte às medidas com sensores termoelásticos
The hydrostatic pressure inside the cell or simply cell turgor is an important component of texture in vegetables and is directly related to firmness. The decrease in cell turgor of plant organs is also an indicator of loss of tissue water. This effect can be perceived visually by wilting accompanied by a dry appearance with the loss of brightness and color
