2. Weed-removal system based on artificial vision and movement planning by A* and RRT techniques
ABSTRACT. The recent exploration of autonomous robotics tasks in agro-industry has permitted the integration of theories of artificial vision and mobile robotics with tasks in precision agriculture. Artificial vision allows for the classification of weeds and crops from images of plantations. With 3D-image processing systems, the location of the weeds is det

4. PARA UMA SUSPENSÃO DO TEMPO ORDINÁRIO - A EXPERIÊNCIA DA FESTA, DO TÉDIO E DO DIVÃ
RESUMO: Este ensaio pretende analisar se, em nossos dias, ainda é possível uma suspensão do tempo ordinário. Ou seja, pretende explorar várias dimensões de nossas vidas nas quais o tempo cronológico poderia ou não ser colocado em suspensão; se sim, tal possibilidade nos levaria a experienciar outra forma de temporalidade? Principio a análise desde

6. Influencia del calcio en la retención de humedad por arcilla
ABSTRACT Bentonite as a raw material is an economical alternative to produce desiccants. The literature indicates that it is a good water adsorbent in relation to the desiccants commonly used in industry (silica gel, molecular sieve). In this sense, it is a valid alternative and an economic option since the clay is a natural compound, which makes it environm

7. Caracterización de resinas epoxi para uso en conectores de ductos flexibles
ABSTRACT In the offshore productions of gas and oil are frequently used flexible pipes. The end fitting is the connection between the flexible pipe body and the production unit, at the assembly of this component is used epoxy resin to fill the free space inside it. This polymeric material holds the tensile armor wires to form the anchoring system. A critical

8. Releasing systems for aerospace industry based upon Shape Memory Alloys: characterization of materials for actuators
ABSTRACT Releasing and deployment maneuvers carried out during space satellites launching are usually performed by utilizing pyrotechnics loads. However, it is considered convenient to replace this technique by others not requiring explosives (Non Explosive Actuators-NEA). This is mainly due to the necessity of reducing high-shock and vibrations induced leve

12. Computer vision system approach in colour measurements of foods: Part II. validation of methodology with real foods
Abstract The colour of food is one of the most important factors affecting consumers’ purchasing decision. Although there are many colour spaces, the most widely used colour space in the food industry is L*a*b* colour space. Conventionally, the colour of foods is analysed with a colorimeter that measures small and non-representative areas of the food and t
