Effect of conjugated system extension on structural features and electron-density distribution in charge–transfer difluoroborates
2021
A comparative structural study of two related donor–acceptor pyridine-based BF2 complexes, namely, 3-(dimethylamino)-1,1-difluoro-1H-pyrido[1,2-c][1,3,5,2]oxadiazaborinin-9-ium-1-uide, C8H10BF2N3O (1), and 3-{(1E,3E)-4-[4-(dimethylamino)phenyl]buta-1,3-dien-1-yl}-1,1-difluoro-1H-pyrido[1,2-c][1,3,5,2]oxadiazaborinin-9-ium-1-uide, C18H18BF2N3O (2), containing a dimethylamino group and either the shortest (in 1) or the longest (in 2) charge-transfer path known until now in this family of compounds, is presented. Single-crystal X-ray diffraction analysis supported by computational investigations shed more light on these systems, indicating, among other aspects, the predominance of C—H...F cont…
Info screens as instruments for value co-creation : case: vehicle inspection industry
2016
Tämän tutkielman tavoitteena on tutkia miten arvo on yhteisluotu autokatsastusasemilla infotaulujen, uusin käyttöönotettu teknologia markkinoinnissa ja palvelun tuottamisessa tapauksen yrityksellä, kautta positiivisen palvelukokemuksen tuottamiseksi. Tutkimus on tulkitseva tapaustutkimus, jonka tiedonkeruu on suoritettu haastattelujen kautta ja analyysissä on käytetty temaattista näkökulmaa, jotta data on pystytty muuttamaan mielekkääksi graafiseksi esitykseksi. Tutkielman tapausyritys on yksityinen katsastusalan toimija, joka tarjoaa katsastuksien lisäksi ajoneuvorekisteröintejä ja kuljettajantutkintoja, muun muassa. Yritys toimii Suomen lisäksi Pohjois-Euroopassa. Tutkielman viitekehyksek…
An empirical study of the understanding of formal propositions about sequences, with a focus on infinite limits
2018
International audience; In this paper, we analyze the answers of one group of high-school students and two groups of first-year University students to a questionnaire designed to test their level of recognition and understanding of the formal definition of the concept of infinite limit. Although this empirical study is ancillary to a larger project centred on didactic engineering, its analysis sheds light on the key issue of the logical prerequisites for the learning of the fundamental concepts of analysis. It also provides a new tool to investigate students' concept-image of limits, and assess the impact of teaching contexts and teaching paths.
Professionals in value co-creation through digital healthcare services
2018
Digitization is changing the dynamics within the service sector, including healthcare. The customer access to information and new ways of interacting with the customer challenge the traditional service within healthcare featured by information asymmetry and autonomous role of professionals in decision making. Digitization introduces new service concepts and roles of service actors benefiting value cocreation among the service network. Customer actively participates in the digital service process, which sets demand for new approach, behavior and skills of the professional interacting with the customer. The present discussion around value cocreation lacks research from the service provider’s …
Decentralized Deployment of Mobile Sensors for Optimal Connected Sensing Coverage
2008
In this paper, we address the optimal connected sensing coverage problem, i.e., how mobile sensors with limited sensing capabilities can cooperatively adjust their locations so as to maximize the extension of the covered area while avoiding any internal “holes”, areas that are not covered by any sensor. Our solution consists in a distributed motion algorithm that is based on an original extension of the Voronoi tessellation.
Economic specialization and diversification at the country and regional level: introducing a conceptual framework to study innovation policy logics
2018
While there has been a shared understanding that innovation policy is about rendering institutional change, there has been an emerging interest in identifying the institutional logics underlying in...
Considering safety issues in minimum losses reconfiguration for MV distribution networks
2009
This paper offers a new perspective over the traditional problem of the multiobjective optimal reconfiguration of electrical distribution systems in regular working state. The issue is indeed here formulated including also safety issues. Indeed, dimensioning the earth electrodes of their own secondary substations, distribution companies take into account the probable future configurations of the network due to transformations of overhead lines into cable lines or realization of new lines. On the contrary, they do not consider that, during normal working conditions. the structure of the network can be modified for long periods as a consequence of reconfiguration manoeuvres, with differences …
THE LIVING LOGICAL SYSTEM PARADIGM THE ECONOMIC CONCEPT AND THE CONCEPT OF LIVING LOGICAL SYSTEM – NECCESARY AND SUFFICIENT PREDICATES
2012
Through the current research we advocate for the conceptualization of economics and the grouping of the Living Logical System (a concept introduced by prof. Phd. Emil Dinga) on economics, with the purpose of increasing the understanding we have on economic forces. The system which we created, as an extention of the Living Logical System, will be called the Economic Living Logical System. The need for such a research is given by the fact that orthodox economic knowledge is considered a prisoner of the mechanical paradigm.
DAE-GP
2020
Estimation of distribution genetic programming (EDA-GP) algorithms are metaheuristics where sampling new solutions from a learned probabilistic model replaces the standard mutation and recombination operators of genetic programming (GP). This paper presents DAE-GP, a new EDA-GP which uses denoising autoencoder long short-term memory networks (DAE-LSTMs) as probabilistic model. DAE-LSTMs are artificial neural networks that first learn the properties of a parent population by mapping promising candidate solutions to a latent space and reconstructing the candidate solutions from the latent space. The trained model is then used to sample new offspring solutions. We show on a generalization of t…
Scatter search for an uncapacitated p-hub median problem
2015
Scatter search is a population-based method that has been shown to yield high-quality outcomes for combinatorial optimization problems. It uses strategies for combining solution vectors that have proved effective in a variety of problem settings. In this paper, we present a scatter search implementation for an NP -hard variant of the classic p-hub median problem. Specifically, we tackle the uncapacitated r-allocation p-hub median problem, which consists of minimizing the cost of transporting the traffics between nodes of a network through special facilities that act as transshipment points. This problem has a significant number of applications in practice, such as the design of transportati…
