49. Conocimiento, aprendizaje y capital social como motor de desarrollo
This paper analyses the emergence of the Knowledge Society as a consequence of the combined impact of the high rate of scientific progress that characterises this turn of century, the recent breakthroughs in information and communication technologies, and the globalisation process that is transforming production and finance markets and producing profound cha

50. State and parameter estimation based on a nonlinear filter applied to an industrial process control of ethanol production
Most advanced computer-aided control applications rely on good dynamics process models. The performance of the control system depends on the accuracy of the model used. Typically, such models are developed by conducting off-line identification experiments on the process. These experiments for identification often result in input-output data with small output

51. Evaluation of the quality of wooden plates through a fuzzy inference system based in adaptative networks. / Avaliação da qualidade de placas de madeira através de um sistema de interferência nebuloso baseado em redes adaptativas.
Automatic visual inspection is an important task for industrial productivity. It could be applied for quality control or for replacing manual work under dangerous or repetitive activity. The classification stage in quality control of the industrial production is often based on the human knowledge. It seems, therefore, to be a great concern to supply an autom

52. SISTEMA HÍBRIDO DE APOIO À DECISÃO PARA DETECCÇÃO E DIAGNÓSTICO DE FALHAS EM REDES ELÉTRICAS / HYBRID DECISION SUPPORT SYSTEM FOR DETECTION AND DIAGNOSIS OF FAULTS IN ELECTRICAL NETWORKS
This work examines the application of hybrid systems based on Artificial Neural Networks (ANN) and Expert Systems (ES) in detecting and diagnosing faults in Electrical Systems. The research consists of three main parts: the study of cases. In the study of problem, was examined, the importance of detecting and diagnosing faults in Electrical Systems concentra

53. A conserved trimerization motif controls the topology of short coiled coils
In recent years, short coiled coils have been used for applications ranging from biomaterial to medical sciences. For many of these applications knowledge of the factors that control the topology of the engineered protein systems is essential. Here, we demonstrate that trimerization of short coiled coils is determined by a distinct structural motif that enco

54. Integration of transcriptomics and metabolomics for understanding of global responses to nutritional stresses in Arabidopsis thaliana
Plant metabolism is a complex set of processes that produce a wide diversity of foods, woods, and medicines. With the genome sequences of Arabidopsis and rice in hands, postgenomics studies integrating all “omics” sciences can depict precise pictures of a whole-cellular process. Here, we present, to our knowledge, the first report of investigation for ge

55. Myxococcus xanthus Chemotaxis Homologs DifD and DifG Negatively Regulate Fibril Polysaccharide Production
The extracellular matrix fibrils of Myxococcus xanthus are essential for the social lifestyle of this unusual bacterium. These fibrils form networks linking or encasing cells and are tightly correlated with cellular cohesion, development, and social (S) gliding motility. Previous studies identified a set of bacterial chemotaxis homologs encoded by the dif lo

56. Quorum Sensing in Nitrogen-Fixing Rhizobia
Members of the rhizobia are distinguished for their ability to establish a nitrogen-fixing symbiosis with leguminous plants. While many details of this relationship remain a mystery, much effort has gone into elucidating the mechanisms governing bacterium-host recognition and the events leading to symbiosis. Several signal molecules, including plant-produced

57. The challenge of contracting for technological information
Contracting to provide technological information (TI) is a significant challenge. TI is an unusual commodity in five ways. (i) TI is difficult to count and value; conventional indicators, such as patents and citations, hardly indicate value. TI is often sold at different prices to different parties. (ii) To value TI, it may be necessary to “give away
