Anonymization as homeomorphic data space transformation for privacy-preserving deep learning
2021
Industry 4.0 is largely data-driven nowadays. Owners of the data, on the one hand, want to get added value from the data by using remote artificial intelligence tools as services, on the other hand, they concern on privacy of their data within external premises. Ideal solution for this challenge would be such anonymization of the data, which makes the data safe in remote servers and, at the same time, leaves the opportunity for the machine learning algorithms to capture useful patterns from the data. In this paper, we take the problem of supervised machine learning with deep feedforward neural nets and provide an anonymization algorithm (based on the homeomorphic data space transformation),…
Clean Agent Selection Approached by Fuzzy TOPSIS Decision-Making Method
2008
Abstract. It is well known that halons are ozone-depleting substances and their release into the atmosphere has contributed in the last decades to the reduction in the ozone layer. In consequence to the Montreal Protocol, an international agreement designed to gradually eliminate the use of such substances, fire protection industry researchers faced the challenge of finding effective solutions to replace halon extinguishers. This research aims to provide a method to support the decision maker in the selection of the most suitable extinguisher substance for a specific application. According to such framework, a set of quantitative and qualitative criteria has been established in the decision…
A survey on algebraic dilatations
2023
In this text, we wish to provide the reader with a short guide to recent works on the theory of dilatations in Commutative Algebra and Algebraic Geometry. These works fall naturally into two categories: one emphasises foundational and theoretical aspects and the other applications to existing theories.
Sex differences in food choices, adherence to dietary recommendations and plasma lipid profile in type 2 diabetes
2016
Background and aims Diabetic women have a more adverse plasma lipid profile than men. Sex differences in dietary habits may play a role, but are little investigated. The study evaluates the quality of diet, adherence to the nutritional recommendations of the Diabetes and Nutrition Study Group and their relation with plasma lipid in men and women with diabetes. Methods and results We studied 2573 people, aged 50–75, enrolled in the TOSCA.IT study (clinicaltrials.gov; NCT00700856). Plasma lipids were measured centrally. Diet was assessed with a semi-quantitative food frequency questionnaire. Women had a more adverse plasma lipid profile than men. Women consumed significantly more legumes, veg…
On elliptic equations involving the 1-Laplacian operator
2018
El objetivo de esta tesis doctoral es dar a conocer los resultados obtenidos sobre existencia, unicidad y regularidad de las soluciones de diferentes ecuaciones elípticas regidas por el operador 1-laplaciano. El primer capítulo está dedicado al estudio de la ecuación - div (Du/|Du|) + g(u) |Du| = f(x) en un subconjunto abierto y acotado U de R^N con frontera Lipschitz, con la condición de Dirichlet u=0 en la frontera, tomando una función f positiva y siendo g una función real, continua y positiva. Por un lado, obtenemos soluciones no acotadas cuando el dato f pertenece al espacio de Marcinkiewicz L^{N,\infty}(U), por lo que debemos introducir la definición apropiada para este tipo de soluci…
Reliģiski-filozofiski raksti, XXIII
2017
Religious-philosophical writings XXIII are devoted to the international conference “The Church and the Totalitarian Regime: Secularization and Strategies of Survival”. This conference was organised by the researchers of the Institute of Philosophy and Sociology of the University of Latvia within the framework of the project of the Latvian Council of Science “Thematization of Religious Experience in the Situation of Post-Liberal Spirituality: Latvian Case”. The conference took place in Riga on the 27th–28th of October 2016. The conference discussed the following issues: Church-power relations in a totalitarian state; politics and legislation in the field of religion; administrative control i…
A New Spatial Shift‐Share Decomposition: An Application to Tourism Competitiveness in Italian Regions
2020
The paper proposes a new version of spatial shift-share decomposition to improve on the various approaches to conventional shift-share analysis found in the literature. The novelty of our proposal is that it enables researchers to assess spatial competitiveness effects controlling for the influence of industrial specialization at both regional and neighborhood level. This new version is applied to inbound tourism in Italian regions and enables us to identify the best and worst performers. Our empirical results identify favorable scenarios in some areas of the country, such as Sardinia as well as regional advantage in a sizeable number of well-known destinations.
Tourism destination and the role of trust
2012
Tourism destinations increasingly pose new challenges to the organizational and management aspects of tourism. The non-cooperative behavior of some companies, the difficulties of sharing a system of values, the absence or inadequacy of destination managers keep some destinations off the map of growth that is sought for by the stakeholders and shareholders of a given resort. This difficulty seems to lie in the scarce knowledge of the system of relations existing between firms and their degree of cooperation. The application of Social Network Analysis (SNA) and some indicators for network analysis provides a clearer and more analytical map of the links between tourism businesses located withi…
Tourism association development tendencies in Latvia
2019
Tourism as one of the leading industries has gained attention from scholars that are researching different influencing factors of tourism destination development. One of the challenges that tourism destinations need to overcome is heterogeneous nature of tourism industry that could be solved with the help of professional and regional tourism associations. Current tourism technology from one side creates additional potential for tourism enterprises and destinations, from other side it could decrease need for traditional tourism associations. The Investment and Development Agency of Latvia (LIAA) indicates eighteen active tourism associations in Latvia. These tourism associations have been go…
Tourism Destination Brokers: a network analytic approach
2022
Understanding the interactions of tourist companies could be relevant for the destination’s organisation and management. The present article employs a network analysis to examine inter-organisational interactions and the various roles that some companies assume in tourism destinations. The results reveal the existence of a network in which enterprises, identified as brokers, take on strategic roles both within and outside of their specific sub-sectors of origin. This study proposes new social network analysis indicators to identify the distinctive and prevalent position of company brokers, who manage inter-organisational relations by spontaneously assuming specific roles within the tourist …
