Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers
No full textIn the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)
Diseño de un convertidor CD-CD para aplicaciones de micropotencia
No full text“Los convertidores CD-CD han estado presentes desde que el uso de la electricidad se convirtió en una práctica común. A través de los años muchos avances tecnológicos han dado lugar a una amplia variedad de diferentes tipos y aplicaciones para convertidores CD-CD. Existen varias técnicas de conversión de voltaje: conversión de voltaje CA en voltaje regulado CD, conversión de voltaje de CD no regulado en voltaje CA (esta operación es normalmente llamada inversión), conversión de voltaje no regulado CD en voltaje CD regulado (este trabajo de tesis se enfoca en esta categoría), la última técnica es acerca de la generación de alto voltaje de CD [1]. En los últimos años ha surgido una tendencia hacia la baja potencia (100mW - 1W) y convertidores CD-CD de baja tensión (1V - 80V), para su uso principal en aplicaciones que funcionan con baterías. Las dos especificaciones clave para esta reciente generación de convertidores CDCD son la eficiencia de conversión de energía y densidad de potencia. La primera especificación determina la autonomía de la batería de la aplicación de destino y la segunda especificación determina el espacio requerido del convertidor”
Portfolio of recorded performances and exegesis: Messiaen’s musical language for the jazz pianist - an exploration through performance.
No full textMoving beyond Gunther Schuller’s Third Stream amalgamation of classical and jazz, this study explores whether the musical language of Olivier Messiaen can make a valid contribution to jazz piano performance. Initially, my project sought to answer such questions as: What elements of the musical language of Messiaen already exist in the jazz vocabulary? Am I able to extend this further? What are the timbral structures and pianistic effects within Messiaen’s musical language? What will be the most effective application of Messiaen’s musical language to jazz piano performance? Endeavouring to answer the final question led me to consider such aspects as whether the project should be limited to quoting Messiaen motifs, arranging Messiaen melodies, replacing jazz harmonic structures on standards with examples from Messiaen’s musical language or whether it would be better to approach the research conceptually. The work of Hubert Nuss provided encouraging reassurance that this was not an impossible task. In order to articulate this conception, the initial challenge was to decide how the classical and jazz worlds might meet in a ‘Messiaen’ technique. The approach adopted was similar to that used for undergraduate jazz study, namely, immersion in the piano scores and recordings of Messiaen’s music as well as by live performances. This was followed by the development and assessment of a contrived approach when specific techniques, such as tonal colourings or harmonic structures, were developed through prepared exercises and consciously included in my performance. It was then compared with an intuitive approach when no such precise parameters were established. This submission consists of CD recordings of two public recitals and an exegesis. It documents the development of this Messiaen technique and discusses its application in my performances. It also demonstrates the ways that Messiaen’s musical language can be used within jazz piano performance to provide a colour that distinguishes jazz piano performance in a competitive field.Thesis (M.Mus.) -- University of Adelaide, Elder Conservatorium of Music, 201
Statistical estimation of turbulent trailing edge noise
No full textThe efficient computation of turbulent airfoil trailing edge noise is important for the cost-effective design of fixed and rotary-wing aircraft, wind turbines, fans and submarines. Recently, the computation of trailing edge noise has mainly been attempted using either direct or hybrid methods of computational aeroacoustics (CAA). However, many of these approaches rely on expensive transient flow solution methods for acoustic source term calculation, such as direct numerical simulation (DNS) or large eddy simulation (LES), which aren't appropriate for engineering design purposes. This paper will present a new approach for calculating turbulent trailing edge noise. Instead of using DNS or LES for a flow solution, the method uses mean flow solutions (Reynolds Averaged Navier Stokes or RANS) and a statistical model to calculate acoustic source terms and radiated far-field noise. After the method is presented, results showing the noise generated by the passage of turbulent flow past a sharp edged flat plate will be shown. For the purposes of validation, the model will use mean flow data from both DNS and RANS solutions to calculate the acoustic source terms. Simulated noise will then be compared with an empirical model of flat-plate trailing edge noise. The paper will conclude with remarks on the accuracy of the method and a discussion of future test cases required to test its validity in more challenging flow conditions.C. J. Doolan, C.

Which executive functioning deficits are associated with AD/HD, ODD/CD and comorbid AD/HD+ODD/CD?
No full textItem does not contain fulltextThis study investigated (1) whether attention deficit/hyperactivity disorder (AD/HD) is associated with executive functioning (EF) deficits while controlling for oppositional defiant disorder/conduct disorder (ODD/CD), (2) whether ODD/CD is associated with EF deficits while controlling for AD/HD, and (3)~whether a combination of AD/HD and ODD/CD is associated with EF deficits (and the possibility that there is no association between EF deficits and AD/HD or ODD/CD in isolation). Subjects were 99~children ages 6–12 years. Three putative domains of EF were investigated using well-validated tests: verbal fluency, working memory, and planning. Independent of ODD/CD, AD/HD was associated with deficits in planning and working memory, but not in verbal fluency. Only teacher rated AD/HD, but not parent rated AD/HD, significantly contributed to the prediction of EF task performance. No EF deficits were associated with ODD/CD. The presence of comorbid AD/HD accounts for the EF deficits in children with comorbid AD/HD+ODD/CD. These results suggest that EF deficits are unique to AD/HD and support the model proposed by R. A. Barkley (1997).17 p
Generation of highly ionized cadmium plasma columns for a discharge-pumped Nickel-like Cd laser
No full textWe report the observation of strong line emission from Ni-like Cd ions in a capillary discharge plasma. Spectroscopically pure Cd vapor was produced in a room temperature environment utilizing a capacitive discharge. The metal vapor was injected into a capillary channel where it was subsequently excited with fast current pulses of up to 200 kA. These results open the possibility of observing laser amplification in the 3d94d-3d94p line of Ni-like Cd at 13.2 nm and in laser lines of other Nickel-like ions in a discharge-created plasma
