Optimal pareto solutions of a dynamic C chart: An application of statistical process control on a semiconductor devices manufacturing process
2015
The present paper proposes a novel economic-statistical design procedure of a dynamic c control chart for the Statistical Process Control (SPC) of the manufacturing process of semiconductor devices. Particularly, a non-linear constrained mathematical programming model is formulated and solved by means of the ε-constraint method. A numerical application is developed in order to describe the Pareto frontier, that is the set of optimal c charts and the related practical considerations are given. The obtained results highlight how the performance of the developed dynamic c chart overcome that of the related static one, thus demonstrating the effectiveness of the proposed procedure.
Tratamiento jurídico de una enfermedad social. Los trastornos de la conducta alimentaria (TCA)
2018
The boundless increase of people suffering from an Eating Disorder (ED), makes necessary to develop measures related to other factors, in order to overcome the ones characterized of being strictly sanitary. The disease has become a social and cultural phenomenon. The exaltation of the cult to the body, with the stereotype of the extreme thinness linked with beauty and success is causing that, particularly young people, try to achieve an image which, in many cases, can jeopardize their health, that is the reason why the rearrangement of values has become an objective of paramount importance. Therefore, the fight against this social illness requires legal actions in order to prevent it from g…
A European Multi Lake Survey dataset of environmental variables, phytoplankton pigments and cyanotoxins
2018
Under ongoing climate change and increasing anthropogenic activity, which continuously challenge ecosystem resilience, an in-depth understanding of ecological processes is urgently needed. Lakes, as providers of numerous ecosystem services, face multiple stressors that threaten their functioning. Harmful cyanobacterial blooms are a persistent problem resulting from nutrient pollution and climate-change induced stressors, like poor transparency, increased water temperature and enhanced stratification. Consistency in data collection and analysis methods is necessary to achieve fully comparable datasets and for statistical validity, avoiding issues linked to disparate data sources. The Europea…
The rationality of rainy day savers: objective and subjective determinants of individual savings in Britain
2022
Using the largest and richest data on savings in Great Britain, six waves of the Wealth and Assets Survey from the Office for National Statistics, we compare standard life cycle models of saving with models using more 'subjective' measures, and the added dimension of longitudinal data. Whilst the life cycle model provides a benchmark, regular criticisms remain, particularly people's propensity to continue saving at older ages. Data on attitudes attenuate that issue, and panel data largely eliminate it. Our results confirm empirically, for Great Britain, the importance of some of the objective determinants of savings included in life cycle theory. When we look at more subjective ones, we sho…
Solving multiobjective optimization problems with decision uncertainty: an interactive approach
2018
We propose an interactive approach to support a decision maker to find a most preferred robust solution to multiobjective optimization problems with decision uncertainty. A new robustness measure that is understandable for the decision maker is incorporated as an additional objective in the problem formulation. The proposed interactive approach utilizes elements of the synchronous NIMBUS method and is aimed at supporting the decision maker to consider the objective function values and the robustness of a solution simultaneously. In the interactive approach, we offer different alternatives for the decision maker to express her/his preferences related to the robustness of a solution. To conso…
‘Experimental Union’ and Baltic Sea cooperation: the case of the European Union’s Strategy for the Baltic Sea Region (EUSBSR)
2018
In the past, Baltic Sea cooperation has been characterized by a plethora of actors, embracing a wide range of policy objectives, such as the establishment of a good environmental status for the regional sea. In 2009, the European Council endorsed the European Union’s (EU) Strategy for the Baltic Sea Region (EUSBSR) as a new tool in the repertoire of Cohesion Policy and European Territorial Cooperation (ETC). The EUSBSR seeks to foster cross-sectoral coordination and functional cooperation in policy areas of ‘macro-region-level’ relevance, such as transport infrastructure, economic development and environmental protection – thus projecting a ‘soft space’ of transnational Baltic Sea cooperati…
Determinants of COVID-19 Vaccine Rollouts and Their Effects on Health Outcomes
2022
Background Vaccination against the coronavirus disease (SARS-CoV-2) is understood to be the key way out of the COVID-19 pandemic. Limited evidence exists on the determinants of vaccine rollouts and their health effects at the country level. Objective Examine the determinants of COVID-19 vaccine rollouts and their effects on health outcomes. Methods Ordinary least squares regressions with standard errors clustered at the country level for Cross-section and Panel daily data of vaccinations and various health outcomes (new COVID-19 cases, fatalities, intensive care unit (ICU) admissions) for an unbalanced sample of about 200 countries during the period 16 December 2020 to 20 June 2021. Results…
Sectoral policies cause incoherence in forest management and ecosystem service provisioning
2022
Various national policies guide forest use, but often with competing policy objectives leading to divergent management paradigms. Incoherent policies may negatively impact the sustainable provision of forest ecosystem services (FES), and forest multifunctionality. There is uncertainty among policymakers about the impacts of policies on the real world. We translated the policy documents of Finland into scenarios including the quantitative demands for FES, representing: the national forest strategy (NFS), the biodiversity strategy (BDS), and the bioeconomy strategy (BES). We simulated a Finland-wide systematic sample of forest stands with alternative management regimes and climate change. Fin…
Los oficiales y subalternos de la Real Audiencia de Mallorca (1716-1808)
2019
The objective of this work is to know the organic structure of the officers and subordinates of the Royal Court of Majorca during the 18th century, which was the essence of the high judicial administration insular. Because of that, we approached through these relatively extensive professionals, with the description of their functions, who they were and how they obtained their charges. The article ends with an epilogue dedicated to the enlargement of the Royal Court with the creation of the second chamber during the reformist stage of Charles III to improve the high judicial administration insular.
Optimal Operating Point Calculation for Medium Voltage Distribution Systems
2007
The paper deals with the calculation of the optimal working point of a distribution system, equipped with several distributed generators, able to operate also autonomously, i.e. disconnected from the main grid. When connected to the main grid, it appears in general convenient to assign the slack bus role to the bus that represents such a connection. The problem becomes more complex when maximum power transfer constraints through the connection must be taken into account. The adequate slack bus treatment is even more important when the optimal operating condition must refer to the condition subsequent to an intentional or unintentional disconnection from the main grid. The paper presents an …
