In this project, two broad facets in the design of a methodology for performance optimization of indexable carbide inserts were examined. They were physical destructive testing and software simulation.For the physical testing, statistical research techniques were used for the design of the methodology. A five step method which began with Problem definition, through System identification, Statistical model formation, Data collection and Statistical analyses and results was indepthly elaborated upon. Set-up and execution of an experiment with a compression machine together with roadblocks and possible solution to curb road blocks to quality data collection were examined. 2k factorial design was illustrated and recommended for process improvement. Instances of first-order and second-order response surface analyses were encountered. In the case of curvature, test for curvature significance with center point analysis was recommended. Process optimization with method of steepest ascent and central composite design or process robustness studies of response surface analyses were also recommended.For the simulation test, AdvantEdge program was identified as the most used software for tool development. Challenges to the efficient application of this software were identified and possible solutions proposed. In conclusion, software simulation and physical testing were recommended to meet the objective of the project.

Properties advanced of the silicon nitride based ceramics and recent performance on automotive parts manufacture by machining process: Advanced Ceramics, demand Forecast

Automotive parts manufacture by machining process using silicon nitride-based ceramic tool development in Brazil already is a reality. Si 3N4-based ceramic cutting tools offer a high productivity due to their excellent hot hardness, which allows high cutting speeds. Under such conditions the cutting tool must be resistant to a combination of mechanical, thermal and chemical attacks. Silicon nitride based ceramic materials constitute a mature technology with a very broad base of current and potential applications. The best opportunities for Si3N 4-based ceramics include ballistic armor, composite automotive brakes, diesel particulate filters, joint replacement products and others. The goal of this work was to show latter advance in silicon nitride manufacture and its recent evolution on machining process of gray cast iron, compacted graphite iron and Ti-6Al-4V. Materials characterization and machining tests were analyzed by X-Ray Diffraction, Scanning Electron Microscopy, Vickers hardness and toughness fracture and technical norm. In recent works the authors has been proved to advance in microstructural, mechanical and physic properties control. These facts prove that silicon nitride-based ceramic has enough resistance to withstand the impacts inherent to the machining of gray cast iron (CI), compacted graphite iron (CGI) and Ti-6Al-4V (6-4).

Desarrollo de un proceso de normalización semántica de bases de datos en ensayos clínicos

El trabajo se enmarca dentro de los proyecto INTEGRATE y EURECA, cuyo objetivo es el desarrollo de una capa de interoperabilidad semántica que permita la integración de datos e investigación clínica, proporcionando una plataforma común que pueda ser integrada en diferentes instituciones clínicas y que facilite el intercambio de información entre las mismas. De esta manera se promueve la mejora de la práctica clínica a través de la cooperación entre instituciones de investigación con objetivos comunes. En los proyectos se hace uso de estándares y vocabularios clínicos ya existentes, como pueden ser HL7 o SNOMED, adaptándolos a las necesidades particulares de los datos con los que se trabaja en INTEGRATE y EURECA. Los datos clínicos se representan de manera que cada concepto utilizado sea único, evitando ambigüedades y apoyando la idea de plataforma común. El alumno ha formado parte de un equipo de trabajo perteneciente al Grupo de Informática de la UPM, que a su vez trabaja como uno de los socios de los proyectos europeos nombrados anteriormente. La herramienta desarrollada, tiene como objetivo realizar tareas de homogenización de la información almacenada en las bases de datos de los proyectos haciendo uso de los mecanismos de normalización proporcionados por el vocabulario médico SNOMED-CT. Las bases de datos normalizadas serán las utilizadas para llevar a cabo consultas por medio de servicios proporcionados en la capa de interoperabilidad, ya que contendrán información más precisa y completa que las bases de datos sin normalizar. El trabajo ha sido realizado entre el día 12 de Septiembre del año 2014, donde comienza la etapa de formación y recopilación de información, y el día 5 de Enero del año 2015, en el cuál se termina la redacción de la memoria. El ciclo de vida utilizado ha sido el de desarrollo en cascada, en el que las tareas no comienzan hasta que la etapa inmediatamente anterior haya sido finalizada y validada. Sin embargo, no todas las tareas han seguido este modelo, ya que la realización de la memoria del trabajo se ha llevado a cabo de manera paralela con el resto de tareas. El número total de horas dedicadas al Trabajo de Fin de Grado es 324. Las tareas realizadas y el tiempo de dedicación de cada una de ellas se detallan a continuación:  Formación. Etapa de recopilación de información necesaria para implementar la herramienta y estudio de la misma [30 horas.  Especificación de requisitos. Se documentan los diferentes requisitos que ha de cumplir la herramienta [20 horas].  Diseño. En esta etapa se toman las decisiones de diseño de la herramienta [35 horas].  Implementación. Desarrollo del código de la herramienta [80 horas].  Pruebas. Etapa de validación de la herramienta, tanto de manera independiente como integrada en los proyectos INTEGRATE y EURECA [70 horas].  Depuración. Corrección de errores e introducción de mejoras de la herramienta [45 horas].  Realización de la memoria. Redacción de la memoria final del trabajo [44 horas].---ABSTRACT---This project belongs to the semantic interoperability layer developed in the European projects INTEGRATE and EURECA, which aims to provide a platform to promote interchange of medical information from clinical trials to clinical institutions. Thus, research institutions may cooperate to enhance clinical practice. Different health standards and clinical terminologies has been used in both INTEGRATE and EURECA projects, e.g. HL7 or SNOMED-CT. These tools have been adapted to the projects data requirements. Clinical data are represented by unique concepts, avoiding ambiguity problems. The student has been working in the Biomedical Informatics Group from UPM, partner of the INTEGRATE and EURECA projects. The tool developed aims to perform homogenization tasks over information stored in databases of the project, through normalized representation provided by the SNOMED-CT terminology. The data query is executed against the normalized version of the databases, since the information retrieved will be more informative than non-normalized databases. The project has been performed from September 12th of 2014, when initiation stage began, to January 5th of 2015, when the final report was finished. The waterfall model for software development was followed during the working process. Therefore, a phase may not start before the previous one finishes and has been validated, except from the final report redaction, which has been carried out in parallel with the others phases. The tasks that have been developed and time for each one are detailed as follows:  Training. Gathering the necessary information to develop the tool [30 hours].  Software requirement specification. Requirements the tool must accomplish [20 hours].  Design. Decisions on the design of the tool [35 hours].  Implementation. Tool development [80 hours].  Testing. Tool evaluation within the framework of the INTEGRATE and EURECA projects [70 hours].  Debugging. Improve efficiency and correct errors [45 hours].  Documenting. Final report elaboration [44 hours].

A formal object-oriented approach to defining consistency constraints for UML models

We discuss how integrity consistency constraints between different UML models can be precisely defined at a language level. In doing so, we introduce a formal object-oriented metamodeling approach. In the approach, integrity consistency constraints between UML models are defined in terms of invariants of the UML model elements used to define the models at the language-level. Adopting a formal approach, constraints are formally defined using Object-Z. We demonstrate how integrity consistency constraints for UML models can be precisely defined at the language-level and once completed, the formal description of the consistency constraints will be a precise reference of checking consistency of UML models as well as for tool development.

The role of software tools in influencing creative problem solving in engineering design and education

Creativity is increasingly recognised as an essential component of engineering design. This paper describes an exploratory study into the nature and importance of creativity in engineering design problem solving in relation to the possible impact of software design tools. The first stage of the study involved an empirical investigation in the form of a case study of the use of standard CAD tool sets and the development of a systems engineering software support tool. It was found that there were several ways in which CAD influenced the creative process, including enhancing visualisation and communication, premature fixation, circumscribed thinking and bounded ideation. The tool development experience uncovered the difficulty in supporting creative processes from the developer's perspective. The issues were the necessity of making assumptions, achieving a balance between structure and flexibility, and the pitfalls of satisfying user wants and needs. The second part of the study involved the development of a model of the creative problem solving process in engineering design. This provided a possible explanation for why purpose designed engineering software tools might encourage an analytical problem solving approach and discourage a more creative approach.

DESENVOLVIMENTO DE FERRAMENTA PARA MAPEAR COMPETÊNCIAS GERENCIAIS: Estudo de Caso numa Empresa do Ramo Editorial

Muitas organizações enfrentam o desafio de assegurar a sobrevivência em mercados acirradamente competitivos e o desenvolvimento de competências individuais gerenciais passa a ser valorizado. O gerente está em evidência diante desse cenário, desempenhando papéis relevantes nos processos estratégicos e de desenvolvimento organizacional. O mapeamento de competências gerenciais constitui uma linha de pesquisa importante no campo da gestão de pessoas pelo fato dos diagnósticos não poderem ser transferidos automaticamente de um ambiente organizacional para outro. Este trabalho teve como objetivo desenvolver uma ferramenta para mapear as competências gerenciais e realizar o mapeamento em uma empresa do ramo editorial. Tomaram parte do estudo cinco gerentes do mesmo nível hierárquico. A realização do mapeamento conteve análises descritivas de auto e heteropercepção, bem como as diferenças entre as duas modalidades de avaliação. Destaca-se que o objetivo do estudo pôde ser concretizado, pois a aplicação da referida ferramenta permitiu identificar aspectos que necessitam investimentos em ações de capacitação gerencial. Cabe salientar que este trabalho pode contribuir com uma base inicial de conhecimento para a reflexão sobre o alinhamento estratégico da organização de acordo com comportamentos esperados correlacionados com cada uma das 12 competências gerenciais identificadas durante o estudo, bem como suportar novas análises e mapeamentos, oportunizando também a implantação adequada de ações de capacitação, com o objetivo de minimizar os riscos da falta de alinhamento estratégico de acordo com as responsabilidades a serem perseguidas pelos gerentes com a pretensão de melhorar os resultados da empresa pesquisada.

Propiedades psicométricas de los instrumentos para la medición de la actividad física en adultos con discapacidad física relacionada con lesión de médula espinal: una revisión sistemática

Objetivo: Evaluar las propiedades psicométricas de los instrumentos para la medición de la actividad física en adultos de 18-65 años con discapacidad física por lesión de médula espinal. Materiales y métodos: Revisión sistemática. Las bases de datos de Medline, Scopus, Web of Science y 19 revistas especializadas fueron consultadas durante once días entre abril de 2015 y febrero de 2016 para identificar estudios originales de validación, sin límite de tiempo y que estuvieran publicados en español, francés y/o inglés. La calidad metodológica de los instrumentos de medición se evaluó usando las diferentes cajas de propiedades de la lista COSMIN. Resultados: Se identificaron 9229 referencias, de las cuales sólo 12 cumplieron los criterios de inclusión, dando como resultado 13 instrumentos de medición. Se evaluaron seis propiedades psicométricas. La propiedad más común fue la confiabilidad, además se observó que la calidad metodológica de los estudios incluidos no representa los resultados de las propiedades psicométricas de los instrumentos de medición. La calidad metodológica de los instrumentos para la evaluación de la actividad física en población con lesión medular espinal es “baja” para propiedades como consistencia interna, error de medición, sensibilidad, validez de criterio (con excepción del WISCI II que tiene buena validez) y excelente para validez de contenido y fiabilidad. Conclusión: Se ha encontrado que instrumentos empleados hasta el presente en la medición de la actividad física en población con discapacidad física relacionada con lesión de médula espinal han sido creados para otros tipos de discapacidad y otros instrumentos deben ser validados en futuros estudios.

Reducing Urban Transport Energy Dependence: A New Urban Development Framework and GIS-Based Tool

High urban transport energy consumption is directly influenced by transport energy dependence. Dramatic reductions in urban transport energy dependence or consumption are not yet being widely observed despite the variety of urban planning tools currently available. A new urban development framework is presented to tackle this issue that makes use of a recently developed and successfully trialed GIS-based tool, the Transport Energy Specification (TES). The TES was simulated on a neighborhood in Sao Carlos, Brazil. In the simulation, energy dependence was reduced by a factor of 8 through activity location or infrastructure modifications to the built environment.

Development and standardization of the Self-regulation Skills Interview (SRSI): A new clinical assessment tool for acquired brain injury

The Self-regulation Skills Interview (SRSI) is a clinical tool designed to measure a range of metacognitive skills essential for rehabilitation planning, monitoring an individual's progress, and evaluating the outcome of treatment interventions. The results of the present study indicated that the SRSI has sound interrater reliability and test-retest reliability. A principle components analysis revealed three SRSI factors: Awareness, Readiness to Change, and Strategy Behavior. A comparison between a group of 61 participants with acquired brain injury (ABI) and a group of 43 non-brain-injured participants indicated that the participants with ABI had significantly lower levels of Awareness and Strategy Behavior, but that level of Readiness to Change was not significantly different between the two groups. The significant relationship observed between the SRSI factors and measures of neuropsychological functioning confirmed the concurrent validity of the scale and supports the value of the SRSI for post-acute assessment.

The development of new business strategies supported by references of excellence, quality and competitiveness also provides a good link between the estalishment of partnerships aiming at the qualification of education boards at a medium level between the technological school and higher education with a technological foundation. We present a case study as an example depicting the success of Escola Tecnológica de Vale de Cambra.

Phage display as a tool for development of novel therapeutics for breast cancer

Phage display technology is a powerful platform for the generation of highly specific human monoclonal antibodies (Abs) with potential use in clinical applications. Moreover, this technique has also proven to be a reliable approach in identifying and validating new cancer-related targets. For scientific or medical applications, different types of Ab libraries can be constructed. The use of Fab Immune libraries allows the production of high quality and affinity antigen-specific Abs. In this work, two immune human phage display IgG Fab libraries were generated from the Ab repertoire of 16 breast cancer patients, in order to obtain a tool for the development of new therapeutic Abs for breast cancer, a condition that has great impact worldwide. The generated libraries are estimated to contain more than 108 independent clones and a diversity over 90%. Libraries validation was pursued by selection against BSA, a foreign and highly immunogenic protein, and HER2, a well established cancer target. Preliminary results suggested that phage pools with affinity for these antigens were selected and enriched. Individual clones were isolated, however, it was not possible to obtain enough data to further characterize them. Selection against the DLL1 protein was also performed, once it is a known ligand of the Notch pathway, whose deregulation is associated to breast cancer, making it an interesting target for the generation of function-blocking Abs. Selection resulted in the isolation of a clone with low affinity and Fab expression levels. The validation process was not completed and further effort will have to be put in this task in the future. Although immune libraries concept implies limited applicability, the library reported here has a wide range of use possibilities, since it was not restrained to a single antigen but instead thought to be used against any breast cancer associated target, thus being a valuable tool.
