No full textArduino + Visual Basic 6.0 (Make your own software to control Arduino Robot.)
No full textThis book deals with Arduino + Visual Basic 6.0 Serial communication and is a most suitable book for the beginner people in the field of Arduino and Pc based controlling system. Contents are also chosen according to the need of beginner learner. This book will help you to learn about Arduino and Visual Basic 6.0 basic interface. As name suggest this is a practical book so nothing is going to describe in detail just follow the steps and you will able to control all motors leds Arduino base wireless Robot with your own visual basic 6.0 software.A large number of program and do it yourself activity are included to help reader to get a clear understanding of practical controlling. Every example is described with suitable breadboard circuit which made with Fritzing.org http://-fritzing.org/home/software. Which gives a clear idea about circuit implementation with Arduino.And again visual basic 6.0 is a ideal for beginner to make a some cool projects with Arduino. I do all the program with Visual Basic 6.0 which works fine with windows 7 window 8 (according to Microsoft Product Detail).215 hlm.; 20.5 x 25.5 c

Evidence of hybrid speciation in the North American primroses Primula suffrutescens, P. parryi, P. rusbyi and P. angustifolia (Primulaceae)
No full textThe genetic structure of tetraploid (4x = 44) North American species of Primula subgenus Auriculastrum: P. suffrutescens,P. parryi, P. rusbyi, and P. angustifolia was analyzed at seven enzyme loci and compared with that of the related diploidP. cuneifolia and P. nipponica. The studied tetraploid species showed fixed or almost fixed heterozygosity at various loci,indicating a hybrid origin. About half of their alleles were shared with Cuneifolia taxa sampled, suggesting that they arose from crosses involving a maternal Cuneifolia-like ancestor. A preliminary survey of their possible paternal species, as inferred from their genotypes, was carried out among different Primula groups. Several paternal alleles expected were observed in subgenus Aleuritia, particularly among taxa of sect. Crystallophlomis (e.g., P. chionantha, P. minor, and P. nivalis xanthobasis). However, none of these taxa proved to be a suitable paternal species. Hybridization events that originated P. suffrutescens, P. parryi, P. rusbyi, and P. angustifolia presumably occurred during Pleistocene secondary contacts in Beringia and involved a maternalCuneifolia-like ancestor and at least two paternal species, for sect. Suffrutescens and Parryi, respectively. Further studies,involving a genetic survey of Aleuritia taxa from Siberia will be needed to detect such paternal species, if not extinct
Desenvolvimento de um protótipo analisador de vibração de baixo custo para uso em manutenção preditiva
Get PDFDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós- Graduação em Engenharia Mecânica, Florianópolis, 2014.No presente trabalho foi desenvolvido e avaliado um protótipo de equipamento de análise de vibração de baixo custo, incluindo o micro controlador Arduino Due, e acelerômetros da nova tecnologia de micro máquinas MEMS, visando os requerimentos mínimos estabelecidos num programa de Manutenção Preditiva padrão. O Arduino Due é a última versão dos micro controladores Arduino e permite a comunicação entre o acelerômetro e o computador, já que incorpora os protocolos de comunicação SPI e USB. O acelerômetro digital MEMS é o elemento fundamental do protótipo, considerando a sua natureza capacitiva e custo muito inferior ao sensor piezo elétrico padrão, torna-se uma alternativa no desenvolvimento do protótipo. A avaliação do protótipo foi realizada em laboratório e em campo, mas, mostra diferenças consideráveis ao ser comparado com o equipamento de análise do laboratório. As principais deficiências do protótipo são instabilidade nas medições ou medições diferentes em dias diferentes, os espectros de frequências apresentam variações de amplitude e impossibilidade de realizar uma análise em tempo real. Mesmo assim, deve-se lembrar que os elementos selecionados para o desenvolvimento do protótipo são os mais econômicos do mercado, e portanto, um aumento na qualidade pode incidir favoravelmente nos resultados das medições em futuras pesquisas
