Iekšējā tūrisma attīstība Kaļiņingradas reģionā
2015
Kaļiņingradas apgabals ir unikāla Krievijas Federācijas teritorija ar īpašu ģeogrāfisko atrašanās vietu, kurai ir liels dabas un vēsturiskais potenciāls tūrisma attīstībai. Maģistra darba mērķis ir novērtēt situāciju tūrisma jomā šajā reģionā, tā turpmākas attīstības priekšnoteikumus, kā arī sagatavot priekšlikumus, lai sekmētu iekšzemes un starpvalstu tūrisma attīstību.
Verso una dimensione narrativa delle mappe
2021
Tra il pensiero e la costruzione dell’architettura il disegno ha un ruolo baricentrico per connettere i diversi protagonisti di una realizzazione e per coinvolgere la collettività facendo percepire inedite prospettive. La scrittura si rivela utile per esplicitare ciò che nella grafica è sotteso e per stabilire un ordine nuovo nel ragionamento progettuale. I rapporti fra segni e significati si moltiplicano nei sistemi informativi recenti in cui si ha la sensazione di poter dire moltissimo (dati numerici e spaziali) ma a volte sfugge quella sintesi indispensabile per una interpretazione concreta, finalizzata alla costruzione di possibili esperienze fisiche. Per l’esplorazione dell’uso di dive…
Multiagent System for Detecting and Solving Design-Time Conflicts in Civil Infrastructure
2012
One typical source of problems in the Civil Infrastructure domain is the distributed and collaborative nature of the projects in which different profiles of engineers contribute with designs devoted to the interest of their field of expertise. Thus, situations in which there are different conflicts of interests are quite common. A conflict refers to a situation in which the actions of an engineer collide with the interests of other engineers. In this paper, we present a multi-agent system that, thanks to the use of ontologies and rules on those ontologies, is able to detect profilespecific conflict situations and solve them according to the preferences of the parties involved in the conflic…
Prediction and Control: The Specific Role of Business Angels in the Investment Process
2019
International audience; Entrepreneurs and related investors (business angels and venture capitalists) rely on different types of rationalities. Extant research suggests that conflicts resulting from misunderstanding can emerge between entrepreneurs and investors when they adopt different rationalities but must switch those rationalities because of the maturity of their ventures and the degree of uncertainty they face. Relying on three in-depth case studies, this research contributes to both entrepreneurship and effectuation literature by emphasizing the specific role of business angels in helping entrepreneurs switch rationalities when necessary to attract funding resources from venture cap…
Efficacy of plasma rich in growth factor used for dry socket management : a systematic review
2019
Background The main aim of this systematic review was to assess the dry socket management using plasma rich in growth factor (PRGF) in terms of pain relief, alveolar fossa healing, inflammation, the incidence of dry socket. Material and Methods PubMed, Cochrane Library, Elsevier Science Direct, China Biology Medicine (CBM), China National Knowledge Infrastructure (CNKI) and VIP database were searched for the related articles without language limitation. Two reviewers independently searched and evaluated relevant studies. This review has been registered in the website PROSPERO (CRD42018087252). Results 28 articles were retrieved on PubMed and 98 on other electronic databases in the initial s…
The Development of Resilience Management Guidelines to Protect Critical Infrastructures in Europe
2018
The capability to be resilient in the face of crises and disasters is a topic of highest political concern in Europe especially as far as critical infrastructures and urban environments are concerned. Critical infrastructures are systems or part of systems essential for the maintenance of vital societal functions, the disruption or destruction of which would have a significant impact on the well-being of people. Examples of them are transportation services, energy infrastructures, water and wastewater systems, health and emergency services, financial services, communication infrastructures, etc. The symposium focuses on the experience of four different projects funded under the Horizon 2020…
A new low cost power line communication solution for smart grid monitoring and management
2018
Modern smart grids require the improvement of measurement and communication infrastructures of distribution networks, at both medium voltage (MV) and low voltage (LV) levels. Distributed sensing and measurement systems are needed to provide all necessary data for grid monitoring, control and management, as well as for the implementation of a number of smart functionalities, such as remote control of distributed generators (DGs), real time analysis of power flows, automatic meter reading (AMR), demand side management (DSM), grid automation and so on [1]-[6]. Acquired network data include typical electrical network quantities and status variables (such as powers, voltages, currents, switches …
An improvement of NFC-SEC with signed exchanges for an e-prescription-based application
2013
International audience; In the context of an aging population, drug intake can be a potential source of errors leading to death in some cases. Almost all of these errors are unintentional and come from incorrect prescriptions, unsuitable dosages for the patient or incompatibility with other treatments. To limit these risks which are especially important in the elderly or pre-dependency, we propose a secure system for drug treatment through the NFC (Near Field Communication) contact-less communication technology. The proposed system provides security mechanisms such as integrity, authentication, encryption and non-repudiation. To ensure this security, an extension of the international standa…
Resource sharing optimality in WiFi infrastructure networks
2009
In WiFi networks, mobile nodes compete for accessing a shared channel by means of a random access protocol called Distributed Coordination Function (DCF). Although this protocol is in principle fair, since all the stations have the same probability to transmit on the channel, it has been shown that unfair behaviors may emerge in actual networking scenarios. Assuming that a contending node can dynamically change its strategy, by tuning its contention parameters to non-standard values on the basis of channel observations, we prove that, for infrastructure networks with bidirectional traffic and homogeneous application requirements, selfish access strategies are able to reach equilibrium condi…
Real-Time Power Flow Monitoring and Control System for Microgrids Integration in Islanded Scenarios
2019
This article presents an enhanced system for real-time power flow monitoring and control (PFMC) for microgrids integration in medium-voltage (MV) distribution networks. The developed solution includes both system architecture and the monitoring and control algorithms, and it has low implementation and installation costs. It is based on the use of hardware and software solutions previously proposed by the authors, i.e., a distributed measurement, a control and communication architecture, and a supervisory control and data acquisition (SCADA) software, which have been enhanced and integrated for the considered application. The SCADA implements a load flow (LF) algorithm for real-time power fl…
