Advantages of Arrowhead Framework for the Machine Tooling Industry
Get PDFImmersed in the digital era and fully experiencing the changes introduced by the new industrial revolution of the so-called Industry 4.0, there are still many aspects of industrial digitization to resolve. Interoperability among devices and machines is one of the challenges. Sensors, components and machines from different vendors work as independent silos offering large amounts of heterogeneous data which relational capabilities are not fully exploited. Quick development, deployment and testing of new software solutions that take advantage of those data is another important matter. The requirements in terms of equipment resources and engineering efforts is high when planning new implementations. Platforms that enable the efficient application of those solutions at the right level (machine, edge, plant or cloud) are also necessary.(p)(/p)This paper presents an industrial case study on the application of the Arrowhead framework. The framework is implemented in the Machine Tooling ecosystem and enables the integration of grinding machines with other sensors, components or machines. Different software engineering tools offered with Arrowhead are used to design new solutions in Cyber-Physical System and Internet of Things in Industry 4.0 and make them Arrowhead compliant, for fast deployment of platforms and applications (Dockers) or for testing purposes (Management tool). Finally, the potential of agile construction of new applications is analysed by providing an Human-Machine Interface at machine level and the provision of services for data consumption at cloud level
Continuous improvement framework to develop cultural change: case study, capital goods company
Get PDFIn this study, a frame of reference was developed to adapt and execute a continuous improvement process (CIP) for reinforcing a continuous improvement (CI) culture in an organisation. The study was undertaken in a mature capital goods company that did not succeed in institutionalising CI despite deploying many CI tools over the years. The organisation thus needed a model that was adapted to its reality and strengthened the aspects of CI through cultural changes at the organisational level.
Action research was used to implement the CIP, and this research method was reinforced using a hermeneutic phenomenological approach to analyse the results.
The CIP was validated in four units of analysis within the organisation. For the validation, aspects relevant to organisational cultural change and their metrics were identified. The results showed that the main barriers to the development of CI in the case organisation were lack of teamwork and poor assimilation of new CI routines.
The study was applied only in one organisation. Therefore, results cannot be generalized, although the process and methodology followed to adapt and implement the CIP could be applied within other organisations
The paper presents a CI frame of reference and describes how a CIP applied to a small and medium-sized industrial enterprise generated cultural changes and promoted organisational excellence in the pursuit of CI by using a hermeneutic phenomenological methodology approach
A Strategic Approach for Bottleneck Identification in Make-To-Order Environments: A Drum-Buffer-Rope Action Research Based Case Study
Get PDFPurpose: This study focused on providing a strategic perspective for the selection and exploitation of bottlenecks in make-to-order production systems, a largely unexplored field in the literature. The researchers developed a systematic decision-making process that operationalized the first two stages of Goldratt’s drum-buffer-rope methodology. This process was derived from the seminal work of Goldratt, who introduced key insights from the resource-based view and practice-based view strategic perspectives. The process also included original contributions from the authors to understand which purpose should be fulfilled, what decisions should be made and how the process should be applied in an operative way.
Design/methodology/approach: Given the practical nature of the research project, action research was an appropriate methodological approach, since this approach aims to contribute to academic research while solving real-world problems. Additionally, the research process complied with necessary criteria to assure the research quality required for action research.
Findings: The systematic process was successfully tested by means of a case study on a make-to-order company. This case study answered the research question regarding systematically selecting and exploiting a bottleneck to enhance competitive advantage/firm performance.
Originality/value: The key contributions focused on the make-to-order environment and were as it follows: (1) four specific criteria to select the bottleneck, far beyond a load versus capacity perspective (i.e., a strategic perspective inspired by the main concepts of the resource-based view regarding the contribution of strategic resources to sustain competitive advantage). A first case study presenting a partial version of this contribution has been discussed on a previous publication of the authors (Lizarralde, Apaolaza, & Mediavilla, 2019b), which describes the case of production plant of a company dedicated to producing steel tubes by extrusion; (2) a detailed discussion on how to exploit the bottleneck aligned with the practice-based view, which recognised that practices could provide superior performance to organisations; and (3) an overarching systematic process that enables an operative deployment in the specific steps to select strategically the bottleneck and exploit this constraint according to some of Goldratt’s seminal proposals
Evaluación basada en los Resultados de Aprendizaje: Una Experiencia en la Universidad
Get PDFPartiendo de los cambios implementados en la Facultad de Humanidades y Ciencias de la Educación (HUHEZI) de Mondragon Unibertsitatea así como de los propiciados por el desarrollo del Espacio Europeo de Educación Superior (EEES), en este artículo se presenta una experiencia de innovación educativa -en cuanto a redefinición curricular, metodológica y evaluativa- desarrollada en los Grados de Educación Infantil y Educación Primaria de esta Facultad en los cursos 2017-18 (1º) y 2018-19 (1º y 2º) con una participación de 12 tutores, 40 profesores y 365 alumnos. Se fundamenta cómo, tras los cambios curricular y metodológicos habidos en la universidad, es necesario replantear el sistema de evaluación, acorde con dichas transformaciones y con las tendencias actuales de evaluación en Educación Superior. Se detalla la estrategia de evaluación diseñada a partir del perfil profesional y de las competencias a desarrollar en ambos grados y que se articula alrededor de los Resultados de Aprendizaje. Se presenta, con detalle, cómo se implementa el nuevo modelo evaluativo en cuanto a los momentos en que se lleva a cabo, los procedimientos y acciones requeridas, los agentes implicados, los instrumentos utilizados, las interacciones y feedbacks proporcionados, y los criterios evaluativos y de obtención de calificaciones establecidos. Finalmente, y sin intención de obtener generalizaciones -al tratarse de una experiencia que está en proceso de desarrollo-, se reflexiona sobre los aspectos y temáticas clave que pueden facilitar -o bien dificultar- el asentamiento y consolidación de las transformaciones que este tipo de innovación impulsan
An Analysis of the Spanish Universities' Entrepreneurial Activities through Secondary Data (Websites and Reports)
Get PDFOver the past few years, there has been a growing number of studies indicating that entrepreneurial activities performed at universities, such as cooperative research and the creation of spin-offs or patents and licenses, have a positive impact on the socioeconomic development of a country and responding to the challenges at the regional and national levels (Fernández-Nogueira et al., 2018).
Hence, this study aims to assess whether Spanish universities are committed to the mission of encouraging entrepreneurial activities that contribute to the socioeconomic development of a region in particular. To that end, on the one hand, the regional evolution with respect to the entrepreneurial activities conducted by Spanish universities is evaluated through secondary data (websites and reports), and on the other hand, it determines which regions had more or less active entrepreneurial universities. Particularly, the study analyzed the entrepreneurial activities of 76 universities in 17 regions in Spain (Europe).
To conduct the said analysis, the use of a tool is proposed to assess the entrepreneurial nature of universities from a given region, and it comprised a set of observable quantitative indicators that aid in data collection through supporting documentation. Additionally, information was collected and analyzed by triangulating sources and researchers.
The key study findings conclude that a positive evolution could be observed in terms of entrepreneurial results in most of the regions. Regarding the strengths of the Spanish higher education system, it is worth highlighting the number of Offices for the Transfer of Research Results in terms of scientific journals, PhD thesis, and license revenue. As for the system’s weaknesses, less than half of the Spanish regions offer entrepreneurial degrees, with a decrease in the amount of research and development revenue. Furthermore, by being aware of the regional differences, the number of patents and spin-offs has also decreased. Therefore, all actors/stakeholders involved in the higher education institutions should strive toward incorporating entrepreneurial activities for the progress of their respective regions
Towards a Taxonomy for Eliciting Design-Operation Continuum Requirements of Cyber-Physical Systems
Get PDFSoftware systems that are embedded in autonomous Cyber-Physical Systems (CPSs) usually have a large life-cycle, both during its development and in maintenance. This software evolves during its life-cycle in order to incorporate new requirements, bug fixes, and to deal with hardware obsolescence. The current process for developing and maintaining this software is very fragmented, which makes developing new software versions and deploying them in the CPSs extremely expensive. In other domains, such as web engineering, the phases of development and operation are tightly connected, making it possible to easily perform software updates of the system, and to obtain operational
data that can be analyzed by engineers at development time. However, in spite of the rise of new communication technologies (e.g., 5G) providing an opportunity to acquire Design-Operation Continuum Engineering methods in the context of CPSs, there are still many complex issues that need to be addressed, such as the ones related with hardware-software co-design. Therefore, the process of Design-Operation Continuum Engineering for CPSs requires substantial changes with respect to the current fragmented software development process. In this paper, we build
a taxonomy for Design-Operation Continuum Engineering of CPSs based on case studies from two different industrial domains involving CPSs (elevation and railway). This taxonomy is later used to elicit requirements from these two case studies in order to present a blueprint on adopting Design-Operation Continuum Engineering in any organization developing CPSs
Influence of manufacturing tolerances and eccentricities on the unbalanced magnetic pull in permanent magnet synchronous motors
Get PDFEccentricity is an inevitable fault in electric motors and hence its diagnosis is an important topic. Thus, the influence of static and dynamic eccentricities on the harmonics of the frequency spectra of the unbalanced magnetic pull is analyzed.In this study, dimensional tolerances of the rotor and the stator are also considered. All parts have dimensional tolerances in their designs and their real magnitudes vary to some extent from the theoretical values after the manufacturing process. Thanks to the finite element simulations, verified with experimental results, it is observed that the deviations originated by the manufacturing tolerances produce changes in the amplitudes of some harmonics and also additional and characteristic harmonics in the frequency spectra of the unbalanced magnetic pull. These are not negligible and must be taken into account when robust eccentricity detection procedures are defined. Otherwise, harmonics originated by tolerances and by eccentricities can be misidentified
Euskal hezkuntza sisteman eskolatutako marokoar jatorriko gazteak eta euskara
Get PDFImmigraziotik datozen gazteak hazi egiten dira harrera-gizartearen kulturaren eta beren

y la cultura de la sociedad de origen transmitida por sus familias, y deben elegir constantemente
entre los elementos culturales que les ofrece la cultura de origen y la nueva.
En este trabajo hemos analizado el conocimiento de las lenguas (su/s primera/s lengua/s,
euskera y castellano) de 11 jóvenes de origen marroquí residentes en la Comunidad Autónoma
del País Vasco; sus hábitos de uso, los modelos lingüísticos en los que han estado escolarizados,
los elementos obstructivos y facilitadores relacionados con las lenguas que han
encontrado estos jóvenes en la escuela, la transmisión de la primera lengua que hacen sus
madres y padres y, por último, su sentimiento de pertenencia.
Se trata de una metodología cualitativa y para la recogida de datos se han utilizado entrevistas
semiestructuradas y la técnica de análisis de contenidos para la interpretación de textos. Entre otros muchos aspectos, los resultados demuestran que los jóvenes han elegido la
lengua más hablada (castellano) de su localidad de acogida, por lo que el euskera y su primera
lengua han quedado en un segundo plano. En cuanto al modelo lingüístico, la mayoría
de las y los jóvenes han sido escolarizados en el modelo B o han pasado de estar escolarizados
en el modelo D al modelo B. Además, han encontrado dificultades a la hora de aprender
euskera en la escuela, sin embargo, han valorado positivamente el apoyo recibido del profesorado.
En cuanto al sentimiento de pertenencia, estos jóvenes tienen una identidad bicultural
(Suárez-Orozco 2003), ya que se relacionan con ambos grupos.
Estas son, entre otras, las manifestaciones de los jóvenes hechas en relación con las
lenguas en el proceso de socialización que viven en la Comunidad Autónoma del País
Vasco, tanto en el ámbito familiar, como en el escolar y en el de sus amistades.Les jeunes issus de l’immigration évoluent dans la culture de la société qui les reçoit et
dans celle transmise par leurs familles. Ils doivent choisir en permanence entre les éléments
culturels de leur culture d’origine et ceux de la culture d’adoption.
Ce travail analyse la connaissance des langues (leur/s langue/s, basque et espagnol) de
11 jeunes d’origine marocaine résidant dans la Communauté autonome du Pays Basque ;
leurs habitude d’usage, les modèles linguistiques dans lesquels ils ont été scolarisés, les
éléments bloquants et facilitateurs relatifs aux langues que ces jeunes ont rencontrés à
l’école, la transmission de la première langue par leurs parents et enfin, leur sentiment
d’appartenance.
Il s’agit d’une méthodologie qualitative et pour le recueil des données des entretiens semistructurés
ont été menés et la technique d’analyse de contenus pour l’interprétation de
textes a été utilisée.
Sur de nombreux aspects, les résultats démontrent que les jeunes ont choisi la langue
principale (espagnole) de leur lieu d’accueil linguistique, le basque et leur première langue
passant au second plan. Pour ce qui est du modèle linguistique, la majorité d’entre eux ont
été scolarisés dans le modèle B ou bien ils sont passés du modèle D au modèle B. De plus, ils
ont été confrontés à des difficultés lorsqu’il a fallu apprendre le basque à l’école, cependant
ils ont utilisé de façon positive l’appui des enseignants.
Pour ce qui est du sentiment d’appartenance, ces jeunes ont une double culture (Suárez-
Orozco 2003) car ils côtoient les deux groupes culturels. Ce sont les principales réponses des 11 jeunes vivant dans la Communauté autonome du
Pays Basque, relatives aux langues dans le processus de socialisation, tant dans la sphère
familiale que dans la sphère scolaire ou les relations amicales.Young immigrants grow up in the culture of the host society, their culture of origin is
transmitted by their families, and they have to make choices constantly between the cultures
they are offered.
This work examines the language knowledge (first language(s), Basque and Spanish) of
11 young people of Moroccan origin living in the Basque Autonomous Community; their
habits of use with these languages; the language models in which they were educated; the
obstructive and facilitative factors they had at school in connection to languages; the transmission
of their parents' first language; and, finally, the young people’ sense of belonging.
A qualitative methodology was used in the research, and for data collection we used
semi-structured interviews, as well as a content analysis technique to interpret the texts.
Among many other factors, the results show that young people choose the main language
of the host country (Spanish) and, as a result, Basque and their first language remain in the
background. In terms of the language model, most young people were educated in model B,
or switched to model B from model D. They encountered various difficulties in learning
Basque at school, but they also value the support they received from their teachers.
In terms of feelings of belonging, these young people have a bicultural identity (Suárez-
Orozco; Suárez-Orozco 2003) because they are linked to both groups.
These are, among other things, what these 11 young people told us about the process of
socialization in the Basque Autonomous Community, both in their families, at school, and
in connection with their friends’ languages, and which we will explain below
