Uncertainty evaluation in load flow analysis: real MV distribution networks case studies
2018
This work investigates the measurement uncertainty impact on load flow analysis in medium voltage (MV) distribution networks. The considered algorithm is a simplified load flow algorithm (LFA), developed by authors, which is based on the load power measurements at each secondary substation and one voltage measurement at the slack bus (i.e. the voltage at the MV bus bars of the primary substation). In the viewpoint of a real implementation, to reduce monitoring system costs, the LFA makes use of low voltage (LV) load power measurements for all the substations except those of MV users, where MV transducers are usually already installed. The uncertainties on LFA input quantities (load powers a…
ITIL-viitekehyksen mukaisen ongelmanhallintaprosessin kriittiset menestystekijät : tapaustutkimus IT-palveluorganisaatiossa
2016
Tutkielman tarkoituksena on tutkia Information Technology Infrastructure Library (ITIL) -viitekehyksen mukaisen ongelmanhallintaprosessin kriittisiä menestystekijöitä. ITIL-viitekehys on laajasti käytetty kokoelma parhaita käytäntöjä IT-palvelunhallintaan, joita voidaan soveltaa kuhunkin organisaatioon sopivaksi tarpeiden mukaan. Ongelmanhallintaprosessi on yksi palvelunhallinnan prosesseista, jolla on tärkeä rooli insidenttien eli tapahtumien juurisyiden tutkinnassa. Ongelmalla tarkoitetaan yhden tai useamman tapahtuman tarkempaa juurisyytä. Ongelmanhallinnan keskeinen tehtävä on juurisyiden löytäminen ja poistaminen. Kirjallisuuskatsauksessa perehdytään ITIL-viitekehykseen ja ongelmanhall…
Manufacturing export performance and public capital: an analysis by country technology position
2021
The objective of this paper is to examine the relationship between public capital and manufacturing export performance. It also aims at investigating whether this relationship depends on the proximity of a country's technology frontier. To achieve this, we adopted a methodology that estimates the elasticities of public capital as a non-rival factor in a model that considers factor intensity as a mechanism of industrial development. We use an interaction model with panel data from 1999 to 2014 across 35 advanced and less advanced countries. Our results show that in countries far from the technology frontier, public capital accumulation is an element of industrial development as opposed to co…
Cost that is Directly Incurred as a Result of Operating the Train Service on the 1520 mm Rail with Primarily Freight Transportation
2016
AbstractUnder the Directive 2012/34/EU (21 November 2012) “the charges for … [rail] infrastructure … shall be set at the cost that is directly incurred as a result of operating the train service”. This charging rule is new for Baltic States’ railways, where due to the favorable geographic position a full cost application without detalization was possible. Although, a big number of relevant studies on the issue was made in EU, all of them covered only 1435mm railways with primarily passenger transportation. This study has been made in order to understand the impact of train operating on 1520mm rail infrastructure with primarily freight transportation.A gradual model of infrastructure chargin…
The proposal to transform an old limestone quarry into a botanical garden with a rainforest zone: a case study
2019
Nowadays, a significant part of cities is tackling the problems with post-mining areas. This manuscript is an original research which shows possibilities of their reclamation. The aim of the article is to present the proposal of developing the closed limestone quarry and creating a botanical garden. The proposed spatial solutions allow for creating a new, tourist and recreation space, maintaining the natural heritage. The work also assumed carrying out a dendrological inventory, in order to determine the existing dendrofl ora. The required spatial, nature and communication analyses, which illustrate the current condition of the area and defi ne further design works, have also been carried o…
Re-Urban | De-frag. Progetti per trasformare la circonvallazione di Palermo
2014
This article presents a short survey of contemporary approaches to re-cycling, up-cycling and recovering urban freeways. Further, it introduces the assumptions and some initial descriptions of cases study of the Degree studio "In-FRA. Architettura e infrastruttura nella città contemporanea", that Z. Tesoriere conducts since 2013 at the University of Palermo. The studio focuses on how enhancing architectural conditions of urban freeways in contemporary urban realm, with particular attention to the circonvallazione of Palermo.
Rola oraz regionalne zróżnicowanie infrastruktury transportowej w procesach przewozu surowców rolnych i produktów rolno-spożywczych
2017
W artykule skoncentrowano się na wskazaniu rosnącego znaczenia jakości infrastruktury transportowej w transporcie produktów rolnych i rolno-spożywczych. Dokonano analizy istniejącego stanu sieci dróg o twardej nawierzchni w poszczególnych województwach. Stosując taksonomiczne metody porządkowania liniowego sporządzono ranking województw ze względu na poziom rozwoju i jakość infrastruktury transportowej, do oceny której wybrano cztery cechy. Badaniem objęto lata 2010–2015, wyniki badań opracowano na podstawie danych GUS.
Networks and health care systems
1996
The network concept has been successful in the economic littérature and in the health care economics littérature. However the network concept is not easy to define. In the first part, this paper suggests a framework for network conceptions analysis :first, network can be conceived as a structure of economic organisation (such as infrastructure networks), or as a coordination mode, alternative and different from market or hierarchy coordination. In the second part, this paper analyses recent mutations in the health care system (such as cooperation relationships between several hospitals and private clinics, networks between hospitals and ambulatory medical care...) from the network concept a…
Infrastructural and Human Factors Affecting Safety Outcomes of Cyclists
2018
The increasing number of registered road crashes involving cyclists during the last decade, and the high proportion of road crashes resulting in severe injuries and fatalities among cyclists constitutes a global issue for community health, urban development, and sustainability. Nowadays, the incidence of many risk factors for road crashes of cyclists remains largely unexplained. Given the importance of this issue, the present study has been conducted with the aim of determining relationships between infrastructural, human factors and safety outcomes of cyclists. Objectives: This study aimed, first, to examine the relationship between key infrastructural and human factors present in cycling,…
