Shape optimization for Stokes problem with threshold slip boundary conditions
2017
This paper deals with shape optimization of systems governed by the Stokes flow with threshold slip boundary conditions. The stability of solutions to the state problem with respect to a class of domains is studied. For computational purposes the slip term and impermeability condition are handled by a regularization. To get a finite dimensional optimization problem, the optimized part of the boundary is described by B´ezier polynomials. Numerical examples illustrate the computational efficiency. peerReviewed
Potential and challenges in home care service process optimization : a route optimization approach
2016
Aging of the population is an increasing problem in many countries, including Finland, and it poses a challenge to public services such as home care. Vehicle routing optimization (VRP) type optimization solutions are one possible way to decrease the time required for planning home visits and driving to customer addresses, as well as decreasing transportation costs. Although VRP optimization is widely and succesfully applied to commercial and industrial logistics, the home care is a relatively new application area for it. This thesis examines what kind of distance and time savings would be possible to achieve if daily home care operations are optimized in the similar manner as typical VRP op…
Cyberharassment Victimization on Three Continents : An Integrative Approach
2022
This article introduces and applies an integrative model of cyberharassment victimization. The model combines routine activity theory (RAT), the general theory of crime (GTC), and the personal resources approach to analyze risk factors for victimization while acknowledging the protective role of a sense of mastery. Survey respondents were aged 15 to 25 years (N = 4816) from the U.S., Finland, Spain, and South Korea. Logistic regression models were used to analyze cyberharassment victimization. RAT-related factors were positively associated with cyberharassment victimization. Low self-control was positively associated with cyberharassment victimization in the U.S., Finland, and Spain but not…
Hybridizing large neighborhood search and exact methods for generalized vehicle routing problems with time windows
2021
International audience; Delivery options are at the heart of the generalized vehicle routing problem with time windows (GVRPTW) allowing that customer requests are shipped to alternative delivery locations which can also have different time windows. Recently, the vehicle routing problem with delivery options was introduced into the scientific literature. It extends the GVRPTW by capacities of shared locations and by specifying service-level constraints defined by the customers' preferences for delivery options. The vehicle routing problem with delivery options also generalizes the vehicle routing problem with home roaming delivery locations and the vehicle routing problem with multiple time…
Innovative, Translucent and Multi-functional Components for the Building Envelope: technological and performance optimization
2017
The paper describes the actions aimed at the technology and performance optimization of an innovative, multi-functional building component made of precast and pre-stressed glass blocks useful for the construction of sustainable building envelopes able to reduce the energy consumption and to produce clean energy from the sun. The design optimization of different sub-components and the choice of the right materials for guaranteeing their good response in terms of mechanical resistance, thermal and acoustic insulation, light transmission, electricity production, integration with other components, dimensional coordination, are particularly described.
Spatiotemporal hotspots analysis for exploring the evolution of diseases: An application to oto-laryngopharyngeal diseases
2013
Abstract View references (14) This paper presents a spatiotemporal analysis of hotspot areas based on the Extended Fuzzy C-Means method implemented in a geographic information system. This method has been adapted for detecting spatial areas with high concentrations of events and tested to study their temporal evolution. The data consist of georeferenced patterns corresponding to the residence of patients in the district of Naples (Italy) to whom a surgical intervention to the oto-laryngopharyngeal apparatus was carried out between the years 2008 and 2012
Fuzzy Methods and Approximate Reasoning in Geographical Information Systems
2014
This issue has been dedicated to the usage of fuzzy logic in the context of Geographical Information Systems (GIS) and were receveid the following papers whose contents are described below: - in the paper of A. Hofmann, S. Hoskova-Mayerova, and V. Talhofer, the authors use a GIS tool which is useful to study the influence of geographic and climatic factors on the terrain passability of armed forces and the Integrated Rescue System. - In the first paper of S. Sessa and F. Di Martino, the authors propose the usage of the well known Extended Gustafson-Kessel clustering method, encapsulated in a GIS tool, for detecting hotspots in spatial analysis. The data consist of geo-referenced patterns co…
Characteristics of clinical trials in rare vs. common diseases: A register-based Latvian study.
2017
Background Conducting clinical studies in small populations may be very challenging; therefore quality of clinical evidence may differ between rare and non-rare disease therapies. Objective This register-based study aims to evaluate the characteristics of clinical trials in rare diseases conducted in Latvia and compare them with clinical trials in more common conditions. Methods The EU Clinical Trials Register (clinicaltrialsregister.eu) was used to identify interventional clinical trials related to rare diseases (n = 51) and to compose a control group of clinical trials in non-rare diseases (n = 102) for further comparison of the trial characteristics. Results We found no significant diffe…

La violencia de género en las historias de vida de las mujeres inmigrantes
2018
Este artículo presenta parte de los resultados de un trabajo de campo etnográfico realizado en distintos centros de protección de mujeres de la Comunidad Valenciana. Su objetivo es desvelar los tipos de violencia de género que han sufrido las mujeres migrantes institucionalizadas desde su perspectiva y punto de vista. La metodología utilizada es de índole cualitativa. A través de la observación participante, documentos personales, informes sociales y, sobre todo, entrevistas en profundidad e informales, se han podido elaborar 6 historias de vida de mujeres migrantes. Respecto a los resultados, cabe señalar que, en sus trayectorias vitales, subyacen distintos tipos de violencia de género fís…
