Jag valde att att utföra den här undersökningen för att se hur olika arbetssätt kan förändra min kreativa skrivarprocess när jag komponerar musik. För att ta reda på det komponerade jag två olika låtar på två olika sätt. Ena arbetssättet gick ut på att jag började med helheten, för att sedan arbeta mig in mot kärnan. Andra arbetssättet gick ut på att jag började med kärnan av låten, för att sedan arbeta mig utåt mot helheten. Under den första arbetsprocessen använde jag mig främst av en DAW (Digital Audio Workstation) när jag komponerade, producerade och skrev musiken. Under den andra arbetsprocessen använde jag en DAW mest för inspelning. Studien är kvalitativ och jag förde loggbok under min skrivarprocess. Resultatet av undersökningen blev två helt olika låtar, som satte olika delar av musikskapandet i fokus. Under skrivandet av låten skriven utifrån och in upplevde jag mycket “flow”. Processen gick ut på att komponera i stora penseldrag. Under skrivandet av låten komponerad inifrån och ut så hamnade sångens uttryck och känsla mycket i fokus. Här ägnade jag mig mer tid åt detaljerna, och kände att låten på något sätt “fanns” mer, eftersom att jag kunde spela den utan hjälp av en datorn. Processen krävde också mer fysiskt arbete, vilket gjorde att låten kändes mer levande.

International Telemetering Conference Proceedings / October 29-November 02, 1990 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Rapid technology growth in the aerospace industry continues to manifest in increasingly complex weapons systems and system driven weapons systems platforms which must be supported in the flight test environment. This growth in complexity often surpasses the capabilities of many ground based real-time and post-flight processing and display systems, leaving these systems perpetually behind the power curve when compared to data/information processing, presentation and distribution requirements set forth by today’s flight test engineering community. Many flight test programs are accepting less than optimal results from these systems, therefore, the amount of information presently obtained (per flight hour) limits the results acquired during a test program, creating a more costly test and evaluation budget. As an integral participant in the development and testing of high technology aircraft and weapons systems, the U.S. Air Force Flight Test Center’s (AFFTC) Advanced Data Acquisition and Processing Systems (ADAPS) development is bridging the gap between requirements and capability by distributing current system architectures to provide incremental performance upgrades in specific areas of need in lieu of entire system replacements. This paper will discuss the current real-time processing, distribution and display capability that exists at the AFFTC and the planned phased upgrade of this tightly coupled system to a more flexible and extensible distributed architecture that will be increasingly responsive to the dynamic nature of test and evaluation of modern weapons systems and weapons systems platforms.

This work provides an innovative solution for monitoring fatigue for users behind workstations. A web camera was adjusted to work in near infrared range and a system of 880 nm IR diodes was implemented to create an IR vision system to localize and track the eye pupils. The software developed monitors and tracks eyes for signs of fatigue by measuring PERCLOS. The software developed runs on the workstation and is designed to draw limited computational power, so as to not interfere with the user task. To overcome low-frame rate imposed by the hardware limitations and to improve real time monitoring, two-phases detection and tacking algorithm is implemented. The proposed system successfully monitors fatigue at a rate of 8 fps. The system is well suited to monitor users in command centers, flight control centers, airport traffic dispatches, military operation and command centers, etc., but the work can be extended to wearable devices and other environments.

Resumo: A crescente demanda na aquisição de tratores agrícolas vem aumentando a concorrência entre os fabricantes e expondo a carência das empresas em produzir tratores agrícolas que possam atender as nececidades ergonômicas de pequenas e grandes propriedades rurais ampliando a opção do comprador com novos modelos que atendam às suas necessidades de uso. O lançamento de novos modelos de tratores agrícolas traz ao mercado nacional as mais recentes tecnologias ao posto de trabalho do operador de trator. A inserção de novas tecnologias na agricultura vem avançando constantemente em várias áreas, mas, especificamente no posto de trabalho do operador de trator agrícola, estas inovações não caminham na mesma velocidade, quando se utiliza de técnicas não tão atuais para avaliar com precisão o invólucro do operador de trator, dificultando, ainda, ao pesquisador a aquisição de equipamentos atualizados para a coleta de dados ergonômicos, principalmente para as coordenadas tridimensionais. Esta pesquisa teve como objetivo o desenvolvimento de um equipamento que possa coletar as coordenadas tridimensionais dos controles do posto de trabalho do operador de trator, automatizando a inserção dos dados diretamente ao computador e tendo maior precisão das medidas obtidas, eliminando os erros humanos de leitura e digitação. O equipamento proposto é composto de um sistema de angulação horizontal, vertical e um feixe de laser para medições diretas, sendo que os dados coletados por um módulo conversor da angulação, e um sistema de coleta sem fio para o feixe de laser. Com o propósito de coletar os dados, foi desenvolvido um programa computacional chamado de "Ergocoord", na linguagem de programação Delphi. Para os dados coletados foram utilizados tratores novos com potência média de 74 kW, visando não alterar as variáveis da pesquisa...

The launch of new models of tractors brings to the domestic market the latest technologies to the job of the operator of tractor. The introduction of new technologies in agriculture has been advancing steadily in many areas but specifically in the workplace of the operator of an agricultural tractor, these innovations do not go the same speed when using such techniques do not present to evaluate accurately the RTB tractor operator, making it also the researcher to acquire updated equipment for the collection of ergonomic data, especially for three-dimensional coordinates. This study aimed to develop a device that can collect three-dimensional coordinates of the controls of the job of the tractor operator by automating the data is entered directly into the computer and with higher accuracy of measurements obtained by eliminating human error in reading and typing. The proposed equipment consists of a system of horizontal angle, vertical, and a laser beam to direct measurements, and the data collected by a converter module of the angle, and a collection system for wireless laser beam. In order to collect the data, we developed a computer program called "Ergocoord" in the Delphi programming language. For the data collected were used tractors with new average power of 74 kW in order not to change the variables of the research. In the valuation of the proposed equipment used two methodological processes, the traditional method of measurement proposed by the NBR / NM / ISO 5353 - Road rollers, tractors and agricultural and forestry machinery - Point of reference of the seat, and adapted it standard...

<p>Arbetet syftar till att undersöka förutsättningarna för att skapa en virtualiserad utvecklingsmiljö för Windows som installeras och konfigureras utan manuell övervakning. Utvecklare på Sandvik Systems Development (SSD) arbetar ofta med olika utvecklingsverktyg eller använder sig av olika versioner av utvecklingsmiljöer och detta är ett problem. Det är också vanligt att utvecklarna blandar sina kontorsapplikationer med utvecklingsmiljön vilket kan vara en stor säkerhetsrisk. Ett annat stort problem är att tiden kan vara väldigt lång för inhyrda konsulter och nyanställda att få sina utvecklingsmiljöer installerade, vilket resulterar i stora kostnader för SSD. En möjlig lösning till problemen är att använda virtuella maskiner som utvecklingsmiljöer. Arbetet undersöker om det är möjligt att m.h.a. en applikation skapa, installera och konfigurera virtuella maskiner och utvecklingsmiljöer automatiskt. Målmiljön för de virtuella maskinerna är programvarorna WMware Workstation och Virtual PC. Arbetet förklarar även hur virtuella maskiner kan vara till hjälp vid mjukvaruutveckling. Detta arbete visar att det är möjligt att skapa en virtualiserad utvecklingsmiljö som med vissa restriktioner installeras och konfigureras automatiskt.</p>

Title from PDF of title page. / Document formatted into pages; contains 120 pages. / Thesis (M.S.M.E.)--University of South Florida, 2003. / Includes bibliographical references. / Text (Electronic thesis) in PDF format. / ABSTRACT: The goal of this thesis is the kinematic analysis and evaluation of wheelchair mounted robotic arms. More specifically, to address the kinematics of the wheelchair mounted robotic arm (WMRA) with respect to its ability to reach positions commonly required by an assistive device in activities of daily living (ADL). A robotic manipulator attached to a power wheelchair could enhance the manipulation functions of an individual with a disability. In this thesis, a procedure is developed for the kinematic analysis and evaluation of a wheelchair mounted robotic arm. In addition to developing the analytical procedure, the manipulator is evaluated, and design recommendations and insights are obtained. At this time there exist both commercially-available and industrial wheelchair mountable robotic manipulators. The commercially-available manipulators (of which two will be addressed in this research) have been designed specifically for use in rehabilitation robotics. / ABSTRACT: In contrast, industrial robotic manipulators are designed for speed, precision, and endurance. These traits are not required in assistive robots and can actually be dangerous to the operator if mounted onto a wheelchair. Manipulators to be used as WMRAs must be designed specifically for assistive functions in order to be utilized as a wheelchair mounted robotic arm. In an effort to evaluate two commercial manipulators, the procedure for kinematic analysis is applied to each manipulator. Design recommendations with regard to each device are obtained. This method will benefit the researchers by providing a standardized procedure for kinematic analysis of WMRAs that is capable of evaluating independent designs. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.
