Thomas Edison: Success and Innovation through Failure [electronic resource] /
No full textThis book develops a systematic approach to the role of failure in innovation, using the laboratory notebooks of America's most successful inventor, Thomas Edison. It argues that Edison's active pursuit of failure and innovative uses of failure as a tool were crucial to his success. From this the author argues that not only should we expect innovations to fail but that there are good reasons to want them to fail. Using Edison's laboratory notebooks, written as he worked and before he knew the outcome we see the many false starts, wrong directions and failures that he worked through on his way to producing revolutionary inventions. While Edison's strengths in exploiting failure made him the icon of American inventors, they could also be liabilities when he moved from one field to another. Not only is this book of value to readers with an interest in the history of technology and American invention, its insights are important to those who seek to innovate and to those who employ and finance them.Chapter 1.

The importance of pairwork in educational and interdisciplinary initiatives
Get PDFAn early and prominent employee of Google, Georges Harik, recently made the assertion that pairs working together in startups are 20 times more productive than individuals working alone. The author has also personally experienced the boost of what is here termed pairwork in a university setting during the startup phase of several educational and interdisciplinary initiatives. The paper briefly explores pairwork in the history of technology and constructs both qualitative and little quantitative models of pairwork. The quantitative model under reasonable assumptions easily recovers Harik’s 20x boost. The paper also briefly examines the author’s recent experiences with pairwork in four interdisciplinary and educational initiatives

No full textEste trabajo se enfoca en el análisis de las propiedades de absorción de energía de un material compuesto abacá – poliéster, como una alternativa que pueda sustituir o reforzar ciertos elementos de la estructura frontal del autobús para disminuir el riesgo de daños físicos en el conductor durante un choque frontal. Se estudia un material compuesto de matriz poliéster y refuerzo de fibras de abacá, ya que presenta buenas propiedades de absorción de energía, se toma un 30% de fracciones volumétrica de fibra y un 70% de matriz con dos configuraciones de refuerzo: fibra continua longitudinal y discontinua a azar de 10mm. Las probetas tienen la forma del elemento que se reemplazará en la estructura para la simulación de impacto, el cual es un tubo estructural cuadrado de 50x50x3mm, para dar esta forma a las probetas se elaboraron moldes de madera tipo Chuncho. El tipo de estratificación usada es moldeo con compresión. Para los ensayos se utilizó las máquinas y laboratorios de la Escuela Superior Politécnica de Chimborazo, para la caracterización del material,
mediante pruebas de tracción y flexión. Con lo cual se determinó las características y se elaboraron
las curvas de comportamiento del material, para posteriormente realizar la simulación de impacto frontal. La simulación se realiza primero con el material y estructura que se fabrica comúnmente, y en una segunda ocasión reemplazando el material de acero estructural por el material compuesto poliéster-abacá en sus dos configuraciones de fibra. Se evidencia una mejora con el uso del material compuesto con fibra continua longitudinal, ya que se obtiene un menor porcentaje de invasión de los elementos del sistema de dirección en la zona de supervivencia del conductor.This work focuses on the analysis of the energy absorption properties of a material abaca-polyester composite, as an alternative that can replace or reinforce certain elements of the front structure of the bus to reduce the risk of physical harm to the driver during a frontal crash. A composite material of polyester matrix and reinforcement of abaca fibers is studied, since it presents good energy absorption properties, 30% of fractions are taken volumetric fiber and 70% matrix with two reinforcement configurations: continuous fiber
longitudinal and discontinuous at random of 10mm. The specimens have the shape of the item to be will be replaced in the structure for the impact simulation, which is a square structural tube of 50x50x3mm, to give the test tubes this shape, Chuncho-type wooden molds were made. He The type of lamination used is compression molding. For the tests the machines were used and laboratories of the Polytechnic School of Chimborazo, for the characterization of the material, by tensile and bending tests. With which the characteristics were determined and the the behavior curves of the material, to later carry out the impact simulation

There is evidence of an improvement with the use of the material composite with continuous longitudinal fiber, since a lower percentage of invasion of the elements of the steering system in the driver's survival zone
No Underskirts in Africa: Edison Carneiro and the "Lineages" of Afro-Brazilian Religious Anthropology
No full textThe article presents the folklorist, essayist, journalist and anthropologist Edison Carneiro (1912-1972) and situates him among the “lineages” or intellectual affiliations in the context of studies on Afro-Brazilian religious groups. Describing the life of Edison Carneiro, his relationship with American anthropologist Ruth Landes and his participation in the folkloric movement, I look to situate Carneiro among the various intellectual trends
found within the study of Afro-Brazilian religions. I argue that the author occupied an ambiguous position in terms of the African presence in the constitution of Afro-Brazilian religions, showing close proximities to Ruth Landes, Franklin Frazier, Ruth Benedict, Donald Pierson and Robert Park on the one hand, and Melville Herskovitz, Roger Bastide and Arthur Ramos on the other. Carneiro’s studies of Candomblé de Caboclo express this

Análisis comparativo de la calidad de servicio entre las redes actuales y las redes de próxima generación
Get PDFEsta investigación tiene como objetivo realizar un análisis comparativo de la calidad de servicio de transferencia de datos y streaming que ofrece las redes actuales en comparación a las redes de próxima generación, para conocer cuál de las dos redes ofrece mejor calidad de servicio. Se empleó una investigación Cuasi Experimental debido a que se escogió muestras intencionales para la implementación del escenario de pruebas; utilizando la herramienta de emulación de dispositivos de red “GNS3” y de inyector de tráfico “D-ITG”, la cual permite analizar los parámetros de QoS, mediante tráfico generado desde el computador físico (emisor) hacia el equipo virtual (receptor), atravesando la red emulada. Como escenario de pruebas se emuló la salida de la red de la ESPOCH hacia la WAN del ISP, implementando Diffserv sobre MPLS para realizar el respectivo análisis de los parámetros de QoS, donde emitió valores de mejoramiento para el servicio Streaming en un 13,33 % y para el servicio de Datos en un 6,66 %. Se concluye que la salida de la red de la ESPOCH hacia la WAN mejora la calidad de servicio de transferencia de Datos y Streaming, implementando el mecanismo de Servicios Diferidos “Diffserv” sobre MPLS, el mismo que incrementa la eficiencia de una red NGN, ofreciendo mejor calidad de servicio que las redes de computadores actuales.Objective of this research is to perform a comparative analysis of the quality of data transfer service and streaming that offers "current networks" compared to NGN (Next Generation Network), to know which of the two networks provides better quality of service. Used a quasi-experimental research due to intentional samples were chosen for the implementation of the testing scenario; using the emulation tool of network devices "GNS3" (Graphic Network Simulator 3) and traffic injector "D-ITG" (Distributed Internet Traffic Generator), which allows to analyze the QoS parameters, through traffic generated from the physical computer (sender) toward the virtual machine (receiver), crossing the emulated network. As testing scenario is emulated the output network of the ESPOCH toward WAN (Wide Area Network) of ISP (Internet Service Provider), implementing Diffserv (Differentiated Service) over MPLS (Multi Protocol Label Switching) to perform the respective analysis of QoS (Quality of Service) parameters, where values for the Streaming service improvement was obtained around 13.33 % and for the data service around 6.66 %. It is concluded that the output of the ESPOCH network toward the WAN improves the quality of data transfer service and Streaming, implementing the mechanism of Differentiated Services "Diffserv" in MPLS (Multi Protocol Label Switching), the same that increases the efficiency of an NGN network offering better quality of service that the current networks computers
