Patterns for Programming in the Semantic Web

Originally proposed in the mid-90s, design patterns for software development played a key role in object-oriented programming not only in increasing software quality, but also by giving a better understanding of the power and limitations of this paradigm. Since then, several authors have endorsed a similar task for other programming paradigms, in the hope of achieving similar benefits. In this paper we discuss design patterns for the Semantic Web, giving new insights on how existing programming frameworks can be used in a systematic way to design large-scale systems. The common denominator between these frameworks is the combination between different reasoning systems, namely description logics and logic programming. Therefore, we chose to work in a generalization of dl-programs that supports several (possibly different) description logics, expecting that our results will be easily adapted to other existing frameworks such as multi-context systems. This study also suggests new constructs to enforce legibility and internal structure of logic-based Semantic Web programs

A influência de John Dunning na investigação em estratégia e negócios internacionais: Um estudo bibliométrico no Strategic Management Journal

O objectivo deste artigo é analisar a contribuição de John Dunning, na investigação em estratégia e negócios internacionais. Para este estudo, procedemos à análise dos artigos publicados por Dunning e a um estudo bibliométrico no Strategic Management Journal, no período entre 1980 e 2009. Verificamos que além da influência na disciplina de negócios internacionais, a influência de Dunning se estende a teorias e conceitos para além desta. Em particular, revelam-se as ligações com a visão baseada nos recursos, a teoria dos custos de transacção, a teoria evolucionista e mais genericamente com a teoria da empresa multinacional.John Dunning, OLI, paradigma Ecléctico, estudo bibliométrico.

Achieving tightness in dl-programs

Reviewed by Francisco MartinsIn the field of the combination between description logics and rule-based reasoning systems, dl- programs have proved to be a very successful mechanism. One of their recognized shortcomings, however, is their lack of full tightness: the language constructs that feed data from the logic program have a local effect, leaving the knowledge base essentially unchanged throughout. In this paper, we present a construction that we call lifting, which allows predicates to be fully shared between the two components of a dl-program in a systematic way, and show how lifting can be used to provide intuitive solutions to a number of everyday reasoning problems involving the verification of integrity constraints and the implementation of default rules. This construction preserves consistency of the underlying knowledge base and complexity of the overall system. Furthermore, the resulting semantics of default rules has a natural interpretation under the original Reiter semantics

High-resolution seismocardiogram acquisition and analysis system

Several devices and measurement approaches have recently been developed to perform ballistocardiogram (BCG) and seismocardiogram (SCG) measurements. The development of a wireless acquisition system (hardware and software), incorporating a novel high-resolution micro-electro-mechanical system (MEMS) accelerometer for SCG and BCG signals acquisition and data treatment is presented in this paper. A small accelerometer, with a sensitivity of up to 0.164 µs/µg and a noise density below 6.5 µg/ Hz is presented and used in a wireless acquisition system for BCG and SCG measurement applications. The wireless acquisition system also incorporates electrocardiogram (ECG) signals acquisition, and the developed software enables the real-time acquisition and visualization of SCG and ECG signals (sensor positioned on chest). It then calculates metrics related to cardiac performance as well as the correlation of data from previously performed sessions with echocardiogram (ECHO) parameters. A preliminarily clinical study of over 22 subjects (including healthy subjects and cardiovascular patients) was performed to test the capability of the developed system. Data correlation between this measurement system and echocardiogram exams is also performed. The high resolution of the MEMS accelerometer used provides a better signal for SCG wave recognition, enabling a more consistent study of the diagnostic capability of this technique in clinical analysis.This work is supported by FCT with the reference project UID/EEA/04436/2013, COMPETE 2020 with the code POCI-01-0145-FEDER-006941

Análise de conteúdo à parametrização portuguesa relacionada com o Processo Respiratório

Background: data sharing from clinical practice is crucial to support nurses' decision-making process, improve nursing outcomes, and increase the quality of care. In Portugal, International Classification for Nursing Practice is used to document care being necessary for the standardization of this process preventing information redundancy. Objectives: (1) to identify diagnoses and interventions used by Portuguese nurses related to Respiratory Process, (2) to suggest unified diagnoses and interventions syntaxes. Methodology: qualitative study with a content analysis. The sample included data regarding e-documentation of nursing diagnosis and interventions customized in the nursing public information system until 2019. Results: of the initial sample of 1502 diagnoses aroused 28 and from 2060 interventions emerged 73 as the most relevant. The main findings were: two areas of nursing attention, one related to respiratory function and the other to patient's learning abilities, diversity of diagnoses and interventions to express the same needs resulting from a variety of taxonomic misunderstandings, and lack of standardized language. Conclusions nursing documentation have two dimensions representing the complexity of nursing care. It also shows that using standardized language does not prevent information redundancy resulting in different diagnoses and interventions to express the same needs.Marco contextual: el cambio de datos resultantes de la práctica clínica es crucial para apoyar el proceso de toma de decisiones. Portugal, utiliza la CIPE para documentar la práctica clínica, siendo necesaria la estandarización de lo proceso evitando redundancia de información. Objetivos: (1) identificar diagnósticos e intervenciones utilizados por enfermeros portugueses relacionados con el Proceso Respiratorio, (2) sugerir sintaxis unificadas de diagnósticos e intervenciones. Metodología: diseño cualitativo con análisis de contenido. La muestra incluyó datos sobre documentación electrónica en el sistema de información pública de enfermería hasta 2019. Resultados: 1502 diagnósticos surgieron 28 y de 2060 intervenciones surtieron 73 como los más relevantes.

Control System of Upgraded High Voltage for Atlas Tile Calorimeter

The preparation of the upgrade of the ATLAS electronics for the High Luminosity LHC is in full swing. The Tile Calorimeter is preparing the upgrade of its readout electronics and power distribution systems. One of such systems is the high voltage (HV) regulation and distribution system. The new system is based on HVRemote boards mounted in crates located at the counting room. The HV will be delivered to the on-detector electronics using 100 m long cables. The crates will be equipped with a system-on-chip (SoC) that will be responsible for the control and monitoring of the HV boards. The control of the HVRemote and its dedicated HVSupply boards is done by means of a serial peripheral interface (SPI) bus. A SCADA component is under development to communicate with and supervise the crates and boards, and to integrate the HV system in the control system of the detector. The control system will be able to send notifications to the operators when the monitored values are out of range, archive the monitored data and if required, perform automated actions

Upgrade of the ATLAS Tilecal High Voltage system

The high voltage (HV) system of TileCal, the ATLAS central hadron calorimeter, is being upgraded for the HL-LHC, in the so called Phase II Upgrade. In the new configuration for the upgrade, the HV regulation boards are not located inside the detector anymore, they are deployed far from the radiation in a room where there is permanent access for maintenance. This option requires a large number of 100 m long HV cables but removes the requirement of radiation hard boards. HVremote regulation boards and the respective HV supplies boards have been developed and tested, as well as a crate to house the boards. Preliminary results of the performance will be presented
