Music and evolutionary computation

This paper presents a brief history of the western music: from its genesis to serialism and the Darmstadt school. Also some mathematical aspects of music are then presented and confronted with music as a form of art. The question is, are these two distinct aspects compatible? Can computers be of real help in automatic composition? The more appealing algorithmic approach is evolutionary computation as it offers creativity potential. Therefore, the Evolutionary Algorithms are then introduced and some results of GAs and GPs application to music generation are analysed.

You get what you pay for : independent music and Canadian public policy

The aim of this MA thesis is to demonstrate how corporate concentration within the global music industry specifically affects the Canadian music industry's ability to compete for its own national audience as well as audiences worldwide. Federal public policies, regulatory regimes and subsidies are considered within the context of the structure of the global marketplace which is, in effect, an oligopoly controlled by four major corporations. Through an extensive literature review of political economy theory, Canadian public policies and music studies, as well as personal interviews conducted with Canadian musicians, entrepreneurs and public servants, I will situate my research within the body of political economy theory; present a detailed report of the structure of the global music industry; address the key players within the industry; describe the relationship between the major corporations and the independent companies operating in the industry; discuss how new technologies affect said relationships; consider the effectiveness of Canadian public policies in safeguarding the national music industry; and recommend steps that can be taken to remedy the shortcomings of Federal policies and regulatory regimes.

Music and life : unidad didáctica.

Unidad didáctica pensada para el comienzo del segundo ciclo de ESO (tercero). A través de ella se realiza la conexión con el ciclo anterior mediante el repaso de conceptos conocidos pero en situaciones que suponen un mayor grado de dificultad. En su programación se ha seguido el método de tareas, cuyo primer paso es la elección del tema, en este caso la música, que se ha considerado altamente motivador. El contenido de la unidad se ha dividido en tres bloques interrelacionados: el primero orientado al estudio previo de la necesidades e intereses de los alumnos, en el segundo se organizan las actividades en torno a bloques temáticos,con especial énfasis en actividades de producción oral y escrita, y en el tercero se ha dado un mayor peso a la destreza de comprensión lectora y al bloque de reflexión lingüística. Al principio de cada bloque se especifican sus contenidos, así como los objetivos didácticos y una explicación del proceso que se sugiere para su puesta en práctica. También se han programado tareas de evaluación.

Modelling the growth and movement of cyanobacteria in river systems

Bloom-forming and toxin-producing cyanobacteria remain a persistent nuisance across the world. Modelling of cyanobacteria in freshwaters is an important tool for understanding their population dynamics and predicting the location and timing of the bloom events in lakes and rivers. In this article, a new deterministic model is introduced which simulates the growth and movement of cyanobacterial blooms in river systems. The model focuses on the mathematical description of the bloom formation, vertical migration and lateral transport of colonies within river environments by taking into account the four major factors that affect the cyanobacterial bloom formation in freshwaters: light, nutrients, temperature and river flow. The model consists of two sub-models: a vertical migration model with respect to growth of cyanobacteria in relation to light, nutrients and temperature; and a hydraulic model to simulate the horizontal movement of the bloom. This article presents the model algorithms and highlights some important model results. The effects of nutrient limitation, varying illumination and river flow characteristics on cyanobacterial movement are simulated. The results indicate that under high light intensities and in nutrient-rich waters colonies sink further as a result of carbohydrate accumulation in the cells. In turbulent environments, vertical migration is retarded by vertical velocity component generated by turbulent shear stress. (c) 2006 Elsevier B.V. All rights reserved.

Identifying the critical parameters of a cyanobacterial growth and movement model by using generalised sensitivity analysis

Bloom-forming and toxin-producing cyanobacteria remain a persistent nuisance across the world. Modelling of cyanobacteria in freshwaters is an important tool for understanding their population dynamics and predicting the location and timing of the bloom events in lakes and rivers. A new deterministic-mathematical model was developed, which simulates the growth and movement of cyanobacterial blooms in river systems. The model focuses on the mathematical description of the bloom formation, vertical migration and lateral transport of colonies within river environments by taking into account the major factors that affect the cyanobacterial bloom formation in rivers including, light, nutrients and temperature. A technique called generalised sensitivity analysis was applied to the model to identify the critical parameter uncertainties in the model and investigates the interaction between the chosen parameters of the model. The result of the analysis suggested that 8 out of 12 parameters were significant in obtaining the observed cyanobacterial behaviour in a simulation. It was found that there was a high degree of correlation between the half-saturation rate constants used in the model.

Sensitivity analysis of a cyanobacterial growth and movement model under two different flow regimes

Bloom-forming and toxin-producing cyanobacteria remain a persistent nuisance across the world. Modelling cyanobacterial behaviour in freshwaters is an important tool for understanding their population dynamics and predicting the location and timing of the bloom events in lakes, reservoirs and rivers. A new deterministic–mathematical model was developed, which simulates the growth and movement of cyanobacterial blooms in river systems. The model focuses on the mathematical description of the bloom formation, vertical migration and lateral transport of colonies within river environments by taking into account the major factors that affect the cyanobacterial bloom formation in rivers including light, nutrients and temperature. A parameter sensitivity analysis using a one-at-a-time approach was carried out. There were two objectives of the sensitivity analysis presented in this paper: to identify the key parameters controlling the growth and movement patterns of cyanobacteria and to provide a means for model validation. The result of the analysis suggested that maximum growth rate and day length period were the most significant parameters in determining the population growth and colony depth, respectively.

Nostalgia, music and the television past revisited in American dreams

The 1960s-set NBC family drama American Dreams presents not just the recent American past but its musical television as well. This paper examines how the show’s recreation of and interaction with the music show American Bandstand ties together the divergent experiences of a turbulent decade. American Dreams’ reshooting and appropriation of original broadcast footage is intricately interwoven with dramatic action allowing for new layers of commentary and meaning to be read across the music and image relationship. Through intercutting and juxtaposition, its use of music performance goes beyond the regressive recycling of images of nostalgia, as critiqued by Jameson and other theorists of postmodernity, to engage political and social debates through a complex web of reference, reproduction and commentary, presenting a politicised reading of the 1960s that problematises these charges of nostalgia texts as apolitical and ‘historicist’.
