Mechanisms for AAA and QoS Interaction

Proceedings of Third IEEE Workshop on Applications and Services in Wireless Networks, ASWN 2003. Bern, Switzerland, July 2-4, 2003.The interaction between Authentication, Authorization and Accounting (AAA) systems and the Quality of Service (QoS) infrastructure is to become a must in the near future. This interaction will allow rich control and management of both users and networks. DIAMETER and DiffServ are likely to turn into the future standards in AAA and QoS systems, but they are not designed to interact with each other. To face this, we propose a new Diameter-Diffserv interaction model and describe the Application Specific Module (ASM) implemented to allow this interaction. The ASM has been implemented and tested in a complete AAA-QoS IPv6 scenario

A Blueprint for Ocean Literacy: EU4Ocean

In this paper, we discuss the importance of the efficient communication of science results to citizens across the world. In order for people to absorb information, we need to understand the principles and apply the best available means to facilitate the process of increasing global awareness of the changes. This explicitly applies to the verification of how we appeal to people with respect to various environmental issues and, hence, how we can modernize the educational approaches to challenge the global change. We state that, in order to follow the philosophy of sustainable development goals with respect to ocean issues, we need an attractive alternative to the existing areas of consumption. We also state that the ocean issues are at the core of any process aiming to secure sustainability. New methods and tools of education and scientific communication, especially those which are offered by non-formal approaches, are necessary, and we present here some of the activities of the EU4Ocean coalition as best practice examples

A compilation of global bio-optical in situ data for ocean-colour satellite applications – version three

A global in-situ data set for validation of ocean-colour products from the ESA Ocean Colour Climate Change Initiative (OC-CCI) is presented. This version of the compilation, starting in 1997, now extends to 2021, which is important for the validation of the most recent satellite optical sensors such as Sentinel 3B OLCI and NOAA-20 VIIRS. The data set comprises in-situ observations of the following variables: spectral remote-sensing reflectance, concentration of chlorophyll-a, spectral inherent optical properties, spectral diffuse attenuation coefficient and total suspended matter. Data were obtained from multi-project archives acquired via open internet services, or from individual projects, acquired directly from data providers. Methodologies were implemented for homogenisation, quality control and merging of all data. Minimal changes were made on the original data, other than conversion to a standard format, elimination of some points after quality control and averaging of observations that were close in time and space. The result is a merged table available in text format. Overall, the size of the data set grew with 151,673 rows, with each row representing a unique station in space and time (cf 136,250 rows in previous version; Valente et al., 2019). Observations of remote-sensing reflectance increased to 68,641 (cf 59,781 in previous version; Valente et al., 2019). There was also a near tenfold increase in chlorophyll data since 2016. Metadata of each in situ measurement (original source, cruise or experiment, principal investigator) are included in the final table. By making the metadata available, provenance is better documented, and it is also possible to analyse each set of data separately. The compiled data are available at https://doi.pangaea.de/10.1594/PANGAEA.941318 (Valente et al., 2022)

Identificación de las competencias más valoradas por el empresariado en Lambayeque para la contratación de un MBA

El concepto de “competencias” se sigue estudiando, desarrollando e implementado en el ámbito educativo a nivel mundial, haciendo que todas las instituciones educativas requieran conocer las competencias que les permitan formar estudiantes con conocimientos sólidos de acuerdo al área formativa, capacidades cada vez más exigentes, destrezas implacables, habilidades diferentes, valores personales marcados y actitudes que las empresas están necesitando para ser competentes en el mercado laboral. La presente investigación plantea un estudio para conocer sobre los conceptos de competencias laborales desde la óptica del empresariado para la contratación de un MBA a su equipo de trabajo; que competencias genéricas y que competencias específicas debería tener hoy en día un egresado de una Universidad o escuela de negocios que imparta programas de Maestría en Administración de Negocios. Para sustentar el estudio, se toman opiniones importantes también de otros tres sectores involucrados en esto, un clúster denominado los Académicos, profesionales de la rama de la Administración de negocios, el clúster de los Empleados, profesionales MBA que están insertados en el mundo laboral y por último, el clúster de los Estudiantes MBA, personas que están llevando estudios de especialización que tienen una opinión muy importante sobre esto. Es este sentido, se contrastará las opiniones para al final tener un posible modelo de competencias valoradas por el empresariado en el departamento de Lambayeque

Cuando tenemos un tumor óseo maligno del fémur distal con contaminación de la articulación ya sea por extensión del tumor, fracturas secundarias al tumor con trazo intrarticular, o por contaminación en una biopsias tomada de manera inadecuada, debemos realizar resecciones extraarticulares de rodilla, para lograr un control primario del tumor

Classification Rule Mining with Iterated Greedy

In the context of data mining, classi cation rule discovering is the task of designing accurate rule based systems that model the useful knowledge that di erentiate some data classes from others, and is present in large data sets. Iterated greedy search is a powerful metaheuristic, successfully applied to di erent optimisation problems, which to our knowledge, has not previously been used for classi cation rule mining. In this work, we analyse the convenience of using iterated greedy algorithms for the design of rule classi cation systems. We present and study di erent alternatives and compare the results with state-of-the-art methodologies from the literature. The results show that iterated greedy search may generate accurate rule classi cation systems with acceptable interpretability level

Control motion approach of a lower limb orthosis to reduce energy consumption

By analysing the dynamic principles of the human gait, an economic gait‐control analysis is performed, and passive elements are included to increase the energy efficiency in the motion control of active orthoses. Traditional orthoses use position patterns from the clinical gait analyses (CGAs) of healthy people, which are then de‐normalized and adjusted to each user. These orthoses maintain a very rigid gait, and their energy cosT is very high, reducing the autonomy of the user. First, to take advantage of the inherent dynamics of the legs, a state machine pattern with different gains in eachstate is applied to reduce the actuator energy consumption. Next, different passive elements, such as springs and brakes in the joints, are analysed to further reduce energy consumption. After an off‐line parameter optimization and a heuristic improvement with genetic algorithms, a reduction in energy consumption of 16.8% is obtained by applying a state machine control pattern, and a reduction of 18.9% is obtained by using passive elements. Finally, by combining both strategies, a more natural gait is obtained, and energy consumption is reduced by 24.6%compared with a pure CGA pattern

Models of Sports Management in Fitness Centres. Influence of Sex, Age and Sport Frequency. Linear Models vs. Qualitative Comparative Analysis

Knowing the perceptions of users of sports services has always been an object of analysis within sports management. This paper attempts to analyse what influences the satisfaction and future intentions of fitness centre customers, beyond management variables, by using two different methodologies. A sample of 389 users of a private sports centre was used. Both linear relationships between variables and the combination of sets were analysed using fuzzy set Qualitative Comparative Analysis fsQCA. It is concluded that management variables (service quality, satisfaction and perceived value) are very important for the prediction of management models, but that, according to the interaction methodology between variables, both frequency and sociodemographic variables play an important role in achieving satisfied and loyal users of the sports service. For the prediction of customers’ future intentions, within the analysed sets, it is observed that satisfaction and perceived value are the most predictive variables (raw coverage 0.66). Therefore, and as a consequence, a high number of satisfied and loyal users of the service will allow the economic viability of this service to be achieved.Ciencias de la Actividad Física y del Deport

Estrategias de aprendizaje de los estudiantes de enseñanza media de establecimientos educacionales municipales de la provincia de Talca

Understanding that students learn according to age, academic performance, self-esteem and motivation plays an important role in the field of the study of learning strategies in educational psychology, however, understanding such strategies is expressed through the geographical conditions or through the type of education, has been relatively addressed. The objective of the present study is to describe the learning strategies of third year students in public schools from the province of Talca according to geographical area (urbanrural) and type of education (technical, polytechnic or scientific humanist). This quantitative study consists of a descriptive transversal design. The sample consisted of 13 public schools with 362 students, 10 schools from the urban area (n=285) and 3 schools (n=79). Ronald Schmeck’s Inventory of Learning Strategies was applied in addition to measuring variables such as gender, learning type, and the school’s geographical location. The results indicate that an evident difference in learning strategies for each of the variables exist. Regarding gender, significant differences manifests themselves in elaborate processing strategies and methodical study, with the female group being the one that made a greater difference in both strategies. In relation to the geographical area, (rural-urban) differences exist regarding the methodical study strategy; showing greater tendency to use this strategy in the rural group. In conclusion, generating background that can contribute to help and facilitate the search for new educational tactics that facilitate the assimilation of the curriculum in accordance with strategies for students in high school, according to their geographical, cultural and educational contexts.Comprender como los estudiantes aprenden a aprender según edad, rendimiento académico, autoestima y motivación ocupa un lugar importante en el ámbito del estudio de las estrategias de aprendizaje en la psicología de la educación, sin embargo, conocercomo dichas estrategias se expresan según la condición geográfica o el tipo de enseñanza ha sido relativamente abordado. El siguiente estudio tiene como objetivo describir las estrategias de aprendizaje de los estudiantes de tercer año medio de liceos municipales de la provincia de Talca según área geográfica (urbano-rural) y tipo de enseñanza (técnica, politécnica o científico humanista). Consiste en un estudio cuantitativo, de diseño transversal descriptivo. La muestra estuvo conformada por 13 liceos municipales con 364 estudiantes, de ellos 10 liceos pertenecen a zonas urbanas (n = 285) y 3 a zonas rurales (n=79). Se aplicó el Inventario de Estrategias de Aprendizajes de Ronald Schmeck y se midieron variables como género, tipo de enseñanza y ubicación geográfica de la escuela. Los resultados indican que se evidenció que existen diferencias en las estrategias de aprendizajes para cada una de las variables. En cuanto al sexo, las diferencias significativas se manifiestan en las estrategias procesamiento elaborativo y estudio metódico, siendo el grupo femenino aquel que marca una diferencia mayor en ambas estrategias. En relación al área geográfica (rural-urbano) existen diferencias con respecto a la estrategia estudio metódico, mostrándose una mayor tendencia a utilizar esta estrategia en el grupo rural. En conclusión, generar antecedentes que pueden contribuir a ayudar y facilitar la búsqueda de nuevas tácticas educativas que propicien la asimilación del currículum en concordancia on las estrategias que poseen los estudiantes de enseñanza media según sus contextos geográficos, culturales y educacionales
