These virtual replicas offer invaluable opportunities for simulation and optimization for new manufacturing processes, since their most transformative impact may lie in the realm of Advanced Technical Training. This article dives into the integration of Digital Twins into manufacturing systems, with a particular focus on their role in training engineers and technicians for real-world challenges, especially in the stone sector dimension. Through the InovMINERAL 4.0 project, it is possible to demonstrate how Digital Twins serve not just as diagnostic tools but as robust educational platforms. It was introduced a comprehensive remote training algorithm that ensures effective, secure, and hands-on training experiences. The algorithm covers everything from secure VPN setup to real-time machining simulations, providing a holistic training approach that prepar...

The present research aims to understand the contribution of information systems (IS) for strategy, what benefits organisations can achieve through the effective implementation of IS and in which resources organisations should invest, as a way to maximise those benefits and to mitigate the risks associated with IS implementation. The methodology uses data gathered through a questionnaire and analysis is done using structure equation modelling. The results obtained show that the IS have a positive impact in organisations' strategy and that the investments made by organisations in IS implementation are influenced by the benefits and risks perceived by using IS.

The transition witnessed from the Third to the Fourth Industrial Age leads to the emergence of paradigms such as BIM, seeking efficiency in Architecture, Engineering and Construction (AEC) through a global approach and procurement oriented towards standardisable products and I4.0, where production comes to be supported by Cyber-Physical Systems (CPS). Integrated in the AEC supply chain, the OS sector shows Portugal to be the eighth country in OS trade worldwide, and the second per capita, with its competitiveness based on the products customization. BIM represents threats for its sustainability, particularly in firms of the Cluster Portugal Mineral Resources (CPMR). The literature review showed that Service Science (S-S) is an inter-disciplinary scientific field that combin...

Integrated in the AEC supply chain, the ornamental stone sector shows Portugal to be the eighth country in OS trade worldwide, and the second per capita, with its competitiveness coming from customization BIM represents threats for its business sustainability. Supported by the Service Science, the main objective of this research is to conceptualize an empirical framework, which, when applied to a sample of Ornamental Stone companies, allows a conclusive answer how to keep their competitive advantage of products customization in BIM-standardized procurement environment. By monitoring the entire sequence of events, it was found that the Or...

From the literature review we found that in Industry 4.0 operations, customer and provider are value co-creators, and thus, mapping the service process using such service blueprinting becomes useful to boost new dynamics generating positive and measurable innovation outcomes using either quantitative or qualitative indicators, indexed to the different stakeholders' concerns. As recommended by the of Service Science, wealth comes from service innovation among service systems, so, it is necessary to know at the outset which resources are involved in value propositions along the service process. With this research, we have conceptualized an innovative service blueprinting framework for the digital innovation to visualize the bridge between the physical world and the virtual world in Industry 4.0 operations.

In addition gender has a strong influence on mechanism on HRV. However the influence of gender and the underlying mechanisms has not yet been determined, till date no work has been conducted to understand the role of gender on HRV. This is a cross sectional study conducted in Jan-March 2010 with a sample size of 86 (43 male, 43 Female) was calculated based on the results of a study done on similar subjects. The temperature of the laboratory was kept between 25 o c-28 o c and lights subdued. The subjects were asked to void urine before testing and made to sit in the lab comfortably to accustom to the new environment. ECG electrodes were connected for lead II. Baseline Heart Rate and Blood Pressure were recorded. Then at supine rest with the eyes closed and relaxed position, lead II ECG was acquired at the rate of 200 samples/second for 10minutes with the normal breath rate of 12-18/min using RMS Polyrite D hardware, INDIA, which is the data acquisition system. There was no significant difference in time domain measures of HRV in between male and females. But in frequency domain analysis Higher LF power, TP, LF/HF ratio and Lower LF values is seen in females.

The aim is to provide a solution for irrigation management that can be used in a large-scale basis, in different regions of the country at low-cost implementation. Pressure readings from tensiometers are the inputs of the software to be able to inform if irrigation is needed and how long the water should be supplied. Soil water retention mapping can be done in situ, by means of the Vincenty equation combined with GPS coordinates to calculate the distance between two points. In this manner, the soil physical property can be delimited. The regions are stored in a relational database and their characteristic can be retrieved by consulting one or more attributes. The software also has a module of isometric visualization that enables to distinguish the three dimensions of the plots using bi-dimensional graphic processing.

Na AP, a utilização de práticas e soluções de tecnologia de informação proporciona o aumento do nível de informação sobre as etapas de produção, o que permite tomar decisões com mais rapidez e segurança. Porém, o custo para a implantação de soluções de tecnologia de informação (TI) complexas e integradas pode se tornar muito elevado. Soluções de TI baseadas na utilização de Personal Digital Assistants (PDAs) possibilitam que a AP seja aplicada em uma propriedade rural sem exigir grandes investimentos ou mudanças drásticas nos processos produtivos. Com o objetivo de oferecer uma solução simples, eficaz e de baixo custo para o manejo de irrigação em fazendas, este trabalho apresenta uma ferramenta computacional para PDAs.

Among all the available digital technologies and aiming to optimize the Architecture Engineering and Construction (AEC) supply chain, the Building Information Modelling (BIM) is becoming officially mandatory worldwide. Oriented to a zero-waste, zero-ecological footprint and reduced time to execute the constructions, from the BIM, emerges a new procurement model which will affect many sectors integrating this supply chain, especially those more traditional and fragmented ones, such as the Ornamental Stone sector (OS). Addressing this problem through the Service Science perspective, the objective of this research was to conceptualize an Empirical Framework (EF), to evaluate the impact of the Industry4.0 operations on the Time-to-Deliver the products in a digital marketplace context. By applying this EF to a case study related to the Ornamental Stone in Portugal, it was found a positive impact of Industry 4.0 operations on the delivery time in the digital marketplace context.

The proposed end-to-end approach overcomes a typical AEC gap, enables the operationalisation of the sustainable/green building LCA (Life Cycle Assessment) and puts together new collaborative relationships with the owner, among SC stakeholders and with new forms of BIM procurement. The outlined collaborative business model is based on the Quality Control and Assurance framework and provides conceptual consistency to the reintroduction of the owner concerns/satisfaction in the SC, as well as enables consistent and accountable relationships between (smart)materials procurement and building specification. An expert's focus group carried out a preliminary check of the model's interest/applicability, resulting in recommendations for its further detailing and for propositions development into a systematic enquiring process.
