Dutch composer Peter Schat’s (1935-2003) pursuit of a compositional system that could generate and preserve intervallic relationships, while allowing the composer as much flexibility as possible to manipulate musical material, led him to develop the tone-clock system. Fundamentally comprised of the twelve possible trichords, the tone clock permits each to generate a complete twelve-tone series through the “steering” principle, a concept traced to Boulez’s technique of pitch-class set multiplication. This study serves as an overview of Schat’s tone-clock system and focuses primarily on the effects of the steering function in “Genen” (2000). Furthermore, I expand on the tone-clock system by combining transformational theory with Julian Hook’s uniform triadic transformations and my proposed STEER and STEERS functions, which express the procedures of the steering principle as a mathematical formula. Using a series of transformational networks, I illustrate the unifying effect steering has on different structural levels in “Genen,” a post-tonal composition.

A human brain has billions of processing elements operating simultaneously; the only practical way to model this computationally is with a massively-parallel computer. A computer on such a significant scale requires hundreds of thousands of interconnected processing elements, a complex environment which requires many levels of monitoring, management and control. Management begins from the moment power is applied and continues whilst the application software loads, executes, and the results are downloaded. This is the story of the research and development of a framework of scalable management tools that support SpiNNaker, a novel computing architecture designed to model spiking neural networks of biologically-significant sizes. This management framework provides solutions from the most fundamental set of power-on self-tests, through to complex, real-time monitoring of the health of the hardware and the software during simulation. The framework devised uses standard tools where appropriate, covering hardware up / down events and capacity information, through to bespoke software developed to provide real-time insight to neural network software operation across multiple levels of abstraction. With this layered management approach, users (or automated agents) have access to results dynamically and are able to make informed decisions on required actions in real-time.

O principal propósito deste trabalho é desenvolver e caracterizar o veículo robótico ℏelvis III, para ser usado no desenvolvimento de pesquisas na área de controle e navegação de robôs móveis. O sistema de propulsão foi caracterizado para determinar a velocidade real do veículo em quatro tipos diferentes de terrenos (Asfalto, grama, grama-terra e terra). Também foi caracterizado o sistema de esterçamento mediante o modelo cinemático da bicicleta, onde se obteve a relação entre a posição do servo motor encarregado do esterçamento do veículo e o valor do ângulo de esterçamento de uma bicicleta. Foram determinados os valores dos erros CEP (Circular Error Probability) e SEP (Spherical Error Probability) do GPS (Global Positioning System) embarcado no veículo mediante dois testes: um em São Carlos – SP (Brasil) e outro em Villavicencio – Meta (Colômbia). Nesses testes foi caracterizada a IMU (Inertial Measurement Unit) embarcada no veículo, além de verificado o efeito da luz solar no funcionamento do sensor tipo LIDAR (Laser Imaging Detection and Ranging) embarcado no helvis III. Por último, pode-se definir a dinâmica do veículo à frente, com a determinação seu centro de massa, e é apresentado o comportamento das forças sob as rodas quando o veículo fica parado ou em movimento sobre terrenos que geram uma inclinação em algum dos eixos cartesianos. / The main objective of this work is the development and characterization of a robotic vehicle ℏelvis III in order to use it in the development of researches focused on the fields of mobile robotics control and navigation. Initially the propulsion system was characterized in order to determine the real velocity of vehicle in real conditions (four different kinds of grounds were used). In addition to this, the steering system was also characterized by applying the well-known bicycle kinematic model. During these experimental tests we could find the relation between the position of the servo-motor and the value of steering angle of the bicycle model. The real values of CEP (Circular Error Probability) and SEP (Spherical Error Probability) errors of the vehicle embedded GPS (Global Positioning System) were determined based on two experiments: the first one was carried out in São Carlos – SP (Brazil) and the second one in Villavicencio – Meta (Colombia). During the GPS experiments we could also characterize the vehicle embedded IMU (Inertial Measurement Unit). Then we could observe and measure the effect of solar light on the LIDAR sensor (Laser Imaging Detection and Ranging) performance. Finally, the forward vehicle dynamics is described, with the determination of the center of mass of the vehicle and the observation of the normal forces behavior in the vehicle wheels when it is stopped or moved on an inclined floor.

Arbetsförmedlingen genomgår en omfattande digitalisering och är mitt i ett stort förändringsarbete, kallat förnyelseresan, där syftet är att modernisera myndigheten. Tidigare forskning visar att olika faktorer påverkar en implementeringsprocess och belyser också hur den politiskt styrda offentliga förvaltningens tjänstemän har en speciell roll.  Studiens huvudteori är baserad på implementeringsstyrning utifrån Lennart Lundquists styrningsmodell och tre egenskaper hos anställda, förstår, vill och kan, som påverkar om implementeringen får önskat utfall. Syftet med studien är att nå en förståelse för hur arbetsförmedlare upplever implementeringsprocessen kring förändringsarbetet och digitaliseringen som pågår vid myndigheten, och hur förändringarna hanteras.  För att få en förståelse för deras upplevelser används en kvalitativ metod i form av intervjuer.  Resultatet visar att arbetsförmedlarna upplever omfattande problem med tekniken och många upplever även en stor personal- och tidsbrist. Arbetsförmedlarna visar sig dock ändå vara motiverade och ha en i grunden positiv inställning till förändringar. Chefer och ledning upplevs ha varit tydliga i hur de har informerat om förändringarna men förtroendet för dem, och förståelsen från dem, varierar stort. Resultaten visar tydligt att arbetsförmedlare främst har kundens bästa i fokus. Studiens slutsats är att arbetsförmedlarna förstår och vill implementera förändringarna men inte riktigt kan, till följd av teknikproblem och resursbrist. / The Swedish public employment service is under an extensive process of digitalization as well as a big organizational change called ”förnyelseresan”, which purpose is to modernize the authority. Previous research has found different factors affecting the implementation process and also illustrates the special features of public administration employees.  The main theory of this study is based upon implementation steering and three employee characteristics, which a Swedish professor of political science, Lennart Lundquist, highlights: understand, will and can. They are said to determine whether or not the implementation will lead to desired outcome. The purpose of this study is to reach an understanding of how the employees at the Swedish public employment service experience the implementation process regarding the ongoing organizational change, and how these changes are handled, with a main focus on digitalization. Qualitative interviews with the employees have been constructed in order to reach an understanding of their experiences. The study shows extensive problems with technology and many of the employees also experience a great lack of resources, such as time and staff. But still their motivation seems to be high and they seem to have a positive attitude regarding changes in general. The received information from management has been clear and sufficient but the confidence towards management, and perceived understanding from them, varies greatly. The study also shows that the employees seem to have their clients best interests in mind.  The conclusion is that the employees understand and are willing to implement the changes but that they not quite can, due to technical problems and lack of resources.
