Control of a high Precision Double Drive

The speed control system for a concept for cost effective drives with high precision is presented. The drive concept consists of two parallel working drives. The concept is an alternative to direct drives. One big advantage is the use of standard gear boxes with economical components. This paper deals with the control of the drive system consisting of two parts: one drive produces the power for the machine, another drive makes the motion precice and dynamic. Both drives are combined to one double drive by a control system. The drive system is usefull for printing machines and other machines with high power consumption at a nearly constant speed and high accuracy requirements. The calculation for a drive system with 37 kW shows, that the control drive has to supply only about 20 % of the total torque and power needed to compensate the errors of the power drive. The stability of the system is shown by a simulation of the double drive.

Ist Leichte Sprache ein Konzept verständlichen Textens? Leichte Sprache für Menschen mit geistiger Behinderung

Verwaltungsformulare, Verträge, Gesetzestexte, die Bedienungsanleitung einer Kaffeemaschine oder auch der Beipackzettel eines Medikaments – jeder kennt solche Texte und fast immer gibt es ein Problem mit der Verständlichkeit. Was wollen die jetzt von mir? Was soll ich machen? Das sind Fragen, die am Ende offen bleiben. Der Leser steht hilflos vor kompliziert und unverständlich, meist auch ermüdend geschriebenen Texten. Eigentlich sollte aber jeder diese Texte verstehen können. Um die Benutzerfreundlichkeit und die Qualität einer Bedienungsanleitung gewährleisten zu können, sind in Normen, wie VDI 4500, DIN EN ISO 121000 und DIN EN 62079, Kriterien bzgl. Inhalt, Layout und Beschaffenheit festgelegt. Bei der Verständlichkeit wird quasi am Minimum angesetzt, weil wirklich jeder die Anleitung verstehen soll. Doch was ist mit denen, die die Anleitung zwar verstehen sollen, aber eben nicht können? Menschen mit geistiger Behinderung werden im Alltag mit einer Vielzahl an Texten konfrontiert, die sie nicht verstehen. Der Textinhalt bleibt somit ein nicht zu lösendes Rätsel. Dass Menschen mit geistiger Behinderung ein selbstbestimmtes und selbstständiges Leben führen können, wird so von vornherein ausgeschlossen. Die Möglichkeit durch Kommunikation an der Gesellschaft teilzunehmen, wird weitestgehend unterbunden. Um diesem Ausschluss entgegenzuwirken, muss bei der Verwendung von Sprache und Erstellung von Texten unmittelbar bei dieser Zielgruppe angesetzt werden, so dass Texte und Sprache der vorhandenen Lesekompetenz entsprechend zugänglich werden. Hier setzt das Konzept Leichte Sprache an. Durch Unterstützung und Förderung beim Einsatz von Leichter Sprache sollen Menschen mit geistiger Behinderung schulische und berufliche Fähigkeiten erwerben und erfolgreich am sozialen Leben teilnehmen können. In der folgenden Arbeit wird, um Diskriminierung vorzubeugen, zunächst die Begrifflichkeit "geistige Behinderung" geklärt und deren Verwendung festgelegt. Dann wird das Konzept Leichte Sprache vorgestellt. Grundlagen von Verständlichkeit im Allgemeinen und bezogen auf die möglichen Zielgruppen, u.a. Menschen mit geistiger Behinderung, werden erläutert. Um feststellen zu können, ob eine Eingrenzung von Texten notwendig ist, bei denen Verständlichkeit gefördert bzw. überprüft werden soll, wird zwischen verschiedenen Textsorten abgegrenzt. So kann schließlich im Ergebnis überprüft werden, ob Leichte Sprache ein Konzept verständlichen Textens ist.

Avaliação do cumprimento da normativa sobre aspectos gráficos na acta médica portuguesa

Objectivo: Avaliar o grau de ajuste da Acta Médica Portuguesa às normas internacionais de elaboração e apresentação de publicações periódicas. Métodos: Análise do cumprimento das normas internacionais de edição de publicações periódicas, reconhecidas numa recente revisão realizada pela Fundação Espanhola para a Ciências e Tecnologia. Só foram avaliados capítulos relativos à normativa de aspecto, e não os relativos às normas para autores e política editorial. O cumprimento das normas dos capítulos características gerais e índice de fascículos é comparado com o conteúdo da página web da Acta Médica Portuguesa; o capítulo contributos compara-se com o aspecto dos artigos publicados em 2007. Resultados: Em 2007 foram publicados 70 artigos nos seis fascículos do volume 20 da Acta Médica Portuguesa. Entre os 76 critérios avaliados, sete foram considerados não aplicáveis. Dos 69 restantes critérios, a Acta Médica Portuguesa cumpre 27 (39,1%). Discussão: São propostas soluções simples para o cumprimento de 51 critérios (73,9%), deixando 10 critérios como discutíveis tendo em consideração a edição moderna de revistas electrónicas. O presente estudo não avaliou os critérios normativos relativos às normas para autores nem à política editorial, que deveriam ser objecto de outra análise. Conclusão: A Acta Médica Portuguesa cumpre 41% dos critérios normativos analisados para a apresentação de revistas, e com pequenas alterações pode chegar ao cumprimento de 75% dos critérios.

First Annual Report of the Audubon Society of South Carolina

This document initially describes the rampant disregard for game laws in the state, which caused people to write to the Audubon Society to get involved. The responded by printing and distributing pamphlets with South Carolina’s game laws to educate citizens who were possibly violating the laws out of ignorance. The society appointed new wardens to enforce the gaming laws and a list of the new wardens is included in the document. There is a description of the work the wardens are supposed to do as well as their duty and pay. The society enlisted the government to help put a stop to the disregard for the games laws and the president wrote his opinion of their reactions to the problem. The document then includes a treasurer’s report and a list of members of the society. The document ends with the secretary’s report.

Metodologias na banda desenhada : realização de um álbum de BD

This dissertation is an explanation of a methodology applied to the making of a comic book, with all that implies. The various stages of this process will be described, from the time when there was the decision to have ideas for the script to its finalization and subsequent publication of the album "Deixa-me Entrar". With this we intend to scrutinize how the inherent problems were solved in all these steps, either in the narrative construction method, as the visual part, such as drawing, coloring and subtitling were performed always seeking quality, not compromising the quality of the work. The time frame of the book was short since it was aimed for release during the twenty-fifth International Comics Festival of Amadora 2014, one of the main events of this kind in comic book releases. It can be said that this is one of the many events that are part of the context in which the practical component of this work fits, and so it is indispensable to context Comics in Portugal, specifically in a time window since the early twenty-first century, talking about relevant authors in recent years. In this explanation were also described some contractual bureaucracies that had to comply with the publisher "Polvo" and how the dialogue between author and publisher was done. Were also exposed advertising strategies through various platforms as well as how the book was received and concluded how the applied methodology resulted in this case study

Special Section Guest Editorial: Image/Video Quality and System Performance

Rapid developments in display technologies, digital printing, imaging sensors, image processing and image transmission are providing new possibilities for creating and conveying visual content. In an age in which images and video are ubiquitous and where mobile, satellite, and three-dimensional (3-D) imaging have become ordinary experiences, quantification of the performance of modern imaging systems requires appropriate approaches. At the end of the imaging chain, a human observer must decide whether images and video are of a satisfactory visual quality. Hence the measurement and modeling of perceived image quality is of crucial importance, not only in visual arts and commercial applications but also in scientific and entertainment environments. Advances in our understanding of the human visual system offer new possibilities for creating visually superior imaging systems and promise more accurate modeling of image quality. As a result, there is a profusion of new research on imaging performance and perceived quality.

Business Process Modelling based on formal temporal theory with an application to hospital patient flows

Existing Workflow Management Systems (WFMSs) follow a pragmatic approach. They often use a proprietary modelling language with an intuitive graphical layout. However the underlying semantics lack a formal foundation. As a consequence, analysis issues, such as proving correctness i.e. soundness and completeness, and reliable execution are not supported at design level. This project will be using an applied ontology approach by formally defining key terms such as process, sub-process, action/task based on formal temporal theory. Current business process modelling (BPM) standards such as Business Process Modelling Notation (BPMN) and Unified Modelling Language (UML) Activity Diagram (AD) model their constructs with no logical basis. This investigation will contribute to the research and industry by providing a framework that will provide grounding for BPM to reason and represent a correct business process (BP). This is missing in the current BPM domain, and may result in reduction of the design costs and avert the burden of redundant terms used by the current standards. A graphical tool will be introduced which will implement the formal ontology defined in the framework. This new tool can be used both as a modelling tool and at the same time will serve the purpose of validating the model. This research will also fill the existing gap by providing a unified graphical representation to represent a BP in a logically consistent manner for the mainstream modelling standards in the fields of business and IT. A case study will be conducted to analyse a catalogue of existing ‘patient pathways’ i.e. processes, of King’s College Hospital NHS Trust including current performance statistics. Following the application of the framework, a mapping will be conducted, and new performance statistics will be collected. A cost/benefits analysis report will be produced comparing the results of the two approaches.

Melhoria contínua no processo de estampagem de uma empresa da indústria automóvel

A indústria automóvel é um meio competitivo onde cada segundo subaproveitado pode significar a perda de um cliente para a concorrência. Por conseguinte, a eliminação do desperdício poderá representar a linha ténue entre uma organização em sobrevivência e uma organização de excelência. O elevado ritmo de produção, a azáfama e os paradigmas fazem com que se desenvolva uma apatia face ao desperdício que cresce diante dos olhos de todos os colaboradores. Porém, neste projeto, detetaram-se dois alvos de melhoria. O primeiro, relativo à ausência de registo e controlo de alguns parâmetros nas fichas de registo de parâmetros, que propiciava variabilidade nos valores destes a cada produção, bem como uma inadequabilidade de algumas das fichas às diferentes configurações e software das máquinas; e o segundo alvo, referente ao sistema documental de difícil gestão e acesso, desorganizado e obsoleto que dificultava e prolongava a tarefa de troca de ferramenta. Para o primeiro caso, instalaram-se meios de controlo de parâmetros e inseriram-se os campos em falta nas fichas de registo de parâmetros, assim como se personalizaram as mesmas consoante as máquinas para uma utilização mais intuitiva. No segundo, procedeu-se à organização do sistema através de uma ação 5S e de gestão visual, bem como a algumas alterações de layout com o objetivo de alcançar uma diminuição do tempo desperdiçado nessa tarefa, e consequentemente, no tempo de setup.

A Travel Optimization System for Academic Environments

Carpooling initiated in America in the 1970s due to the oil crisis. However, over the past years, carpooling has increased significantly across the world. Some countries have created a High Occupancy Vehicle (HOV) lane to encourage commuters not to travel alone. In additional, carpool websites has been developed to facilitate the connection between the commuters, making it possible to create a compatible match in a faster and efficient manner. This project focuses on carpooling, especially in an academic environment since younger people are more likely to choose carpool. Initially, an intense research was made to examine carpool studies that occurred all over the world, following with a research of higher education institutes that use carpooling as a transportation mode. Most websites created carpools by targeting people from a specific country. These commuters have different origins and destinations making it more complicated to create compatible matches. The objective of this project is to develop a system helping teachers and students from an academic environment to create carpool matches. This objective makes it easier to create carpools because these students and teachers have the same destination. During the research, it was essential to explore, as many as possible, existing carpool websites that are available across the world. After this analysis, several sketches were made to develop the layout and structure of the web application that’s being implemented throughout the project. Once the layout was established, the development of the web application was initiated. This project had its ups and downs but it accomplished all the necessary requirements. This project can be accessed on the link: http://ipcacarpool.somee.com. Once the website was up and running, a web-based survey was developed to study the reasons that motivate people to consider carpooling as an alternative to driving alone. To develop this survey was used a tool called Survey Planet. This survey contained 408 respondents, which 391 are students and 17 are teachers. This study concludes that a majority of the respondents don’t carpool, however they will consider carpooling if there was a dedicated parking space. A majority of the respondents that carpool initiated less than a year ago, indicating that this mean of transportation is recent.
