Energy demand in secondary steel making process: numerical analysis to assess the influence of the ladle working lining properties
No full textIn secondary steel making process, steel scrap is melted in an electric arc furnace,
then poured into a ladle where ferroalloy are added to obtain the desired steel composition.
Energy is also supplied in LF (Ladle Furnace) to guarantee steel temperature required in the
teeming phase. In this paper a simplified, but sound numerical model of the process the ladle
undergoes is presented: it is meant to provide a way to compare energy demand for different
choices of materials used in the ladle or for changes in the ladle work cycle. As an example of
application of the model, energy demand in LF are evaluated and compared for two different
choices of the refractory material used as working lining: magnesia and alumina. To take into
account the reduction of the working lining due to wear processes, energy demand has been
calculated for three different thicknesses. In addition, the beneficial effect of a lid during the
waiting phase after cleaning is investigated

Influence on energy demand of thickness, thermal conductivity, and volumetric heat capacity of ladle working lining in secondary steel-making process
No full textThe secondary steel-making process involves several steps during which steel is kept in a
ladle, that is, a vessel made of an outer steel layer (carpentry), an intermediate refractory layer, and
an internal refractory layer. Unlike the intermediate layer, the internal layer undergoes a progressive
reduction in thickness and a periodic restoration. Traditionally, it is made of alumina or magnesite.
During the process, the ladle undergoes unsteady heating and cooling; therefore, heat transfer
depends on thermal conductivity and heat capacity. This study aims to identify the ladle internal layer
characteristics that affect the energy demand. This analysis investigates the effect of the internal layer
thickness S, volumetric heat capacity C, and thermal conductivity λ. Through the Design Of the
Experiments (DOE), different scenarios have been selected and analyzed by means of numerical
simulations performed on a numerical model defined in COMSOL Multiphysics. The energy demand
as a function of the internal layer properties has been estimated, and it has emerged that low thermal
conductivity and heat capacity values require a lower amount of energy
Investigating Cyber Risks in a Surgical Process for Healthcare Cyber Resilience
No full textThe critical role of cyber resilience in safeguarding critical infrastructure, particularly healthcare systems, necessitates the integration of cybersecurity risks into traditional risk assessments. This study revisits a previously published risk assessment for Coronary Artery Bypass Grafting (CABG) procedures, incorporating cyber risks as an emerging threat. The prioritization, classification, and evaluation processes are redone, considering cyber risks alongside traditional ones. The results are then compared to identify the relative importance of cyber risks and their impact on stakeholder risk perception within the healthcare system. Our findings reveal that cyber risks have become the primary threat to critical healthcare infrastructure. This necessitates an update to traditional risk evaluations, established standards, and response strategies
Settlement and population dynamics of the alien invasive Branchiomma bairdi (Annelida: Sabellidae) in the Mediterranean Sea: two years of observations in the Gulf of Taranto (Italy)
No full textSince the first discovery along the Italian coasts in 2004 of the polychaete Branchiomma bairdi, it has spread very quickly, reaching some localities in very high densities. In order to monitor its colonization, recruitment was investigated by means of PVC panels immersed in the Mar Grande of Taranto (Ionian Sea). Panels were monitored every three months from April 2013 to January 2015. The species showed the ability to settle on bare panels as well as on panels with a developed fouling community. Two years of monitoring identified two different cohorts, with recruits appearing in both years on panels submersed from July to October. Based on these observations B. bairdi is a short-lived species (no more than one year), reproducing at a temperature ranging from 20 to 29°C and reaching sexual maturity three months after recruitment. Oocytes were found in the coelom only in the warmest months and oogenesis was not synchronous either within each individual or within the population. Total annual secondary production was estimated at 43.42 g m−2 year−1. Annual mean biomass was 20.03 g m−2. The corresponding P/B ratio was 2.1678. This study may explain the invasiveness of B. bairdi; indeed, a rapid generation turnover coupled with a short lifespan, rapid growth and early maturity are common traits in most invasive species
Ontologies for Competence-Based Management: A Bibliometric Analysis in the Industrial Sector
No full textCompetence management plays a pivotal role in enhancing the competitiveness of organizations in today's fast-changing business environment. In particular, the use of ontologies for the structured management of competence data has proven to be strategic in various industries (such as, manufacturing, aviation and construction) and for different industrial processes (from supply chain management to product lifecycle management). However, despite their demonstrated utility, there remains a significant gap in the literature regarding the specific implications of employing ontologies for competence management in industrial contexts. Hence, the primary objective of this study is to investigate the implications of employing ontologies for competence management in industrial settings. By conducting a Systematic Literature Review (SLR) and bibliometric analysis about this topic, we aim to shed light on the intricacies of utilizing ontologies in managing competence and identify key areas for future research. The conducted keyword co-occurrence analysis identifies six thematic clusters: "Knowledge Representation of Manufacturing Processes"; "Education for Software Engineering"; "Semantic Technologies for Decision Making"; "AI for Knowledge Management", "Ontologies for Human Resource Management (HRM)" and "Competence Management for Industrial Innovation". From an academic perspective, this paper provides an overview of the implication of ontologies in industrial competence management underscoring the importance of ontologies in structuring competence- related information, facilitating decision-making processes and promoting innovation within organizations. Moreover, the study reveals a growing trend of research in this area, with emerging trends reflecting the integration of ontologies with advanced technologies, such as artificial intelligence and machine learning, which would enable organizations to rapidly adapt to changes in today's industrial environment. From a managerial perspective, instead, the study offers insights into best practices and challenges associated with the adoption of ontologies, guiding strategic decisions toward future trends and innovations in competence management
