Kaukana Kainuussa, valtaväylän varrella : etnologinen tutkimus Kontiomäen rautatieläisyhteisön elinkaaresta 1950-1972
2004
FL Kimmo Lagerblomin etnologian väitöskirjan ”Kaukana Kainuussa, valtaväylän varrella. Etnologinen elinkaaritutkimus Kontiomäen rautatieläisyhteisöstä vuosina 1950-1973.” tarkastustilaisuus. Vastaväittäjänä professori Pekka Leimu (Turun yliopisto) ja kustoksena professori Bo Lönnqvist.Kimmo Lagerblomin tutkimus on ensimmäinen Suomessa tehty väitöskirja, jonka painopiste on rautatieläiskulttuurissa. Kontiomäen lisäksi tutkimuksessa tarkastellaan laajemminkin rautatien historiallista merkitystä sekä Suomessa että muualla. This study is located on Kontiomäki railtown; witch is a small village some 600 kilometres north from Helsinki. Kontiomäki is a typical railtown. The Finnish State Railway C…
The emission reduction potential of electric transport modes in Finland
2021
The transportation sector has become the fastest growing source of greenhouse gas (GHG) emissions. One solution to mitigate the impacts is a shift towards electric modes. Where previous studies have only focused on the replacement of individual modes, our study presents a more holistic approach by comparing land-based, water-based and airborne transportation modes. We study the GHG emission reduction potentials of electric cars, buses, trains, ferries and aircraft in comparison to existing modes on 34 routes within Finland and across the Baltic Sea to Sweden and Estonia. By comparing the GHG emissions in carbon dioxide equivalents (CO2-eq) per passenger kilometer for each mode, we also cons…
Service Provisioning and User Association for Heterogeneous Wireless Railway Networks
2017
In addition to comforting passengers' journey, the modern railway system is responsible to support a variety of on-board Internet services to meet the passenger's demands on seamless service provisioning. In order to provide wireless access to the train, one idea attracting increasing attention is to deploy a series of track-side access points (TAPs) with high-speed data rates along the rail lines dedicated to the broadband mobile service provisioning on board. Due to the heavy data traffic flushing into the base stations (BSs) of the cellular networks, TAPs act as a complement to the BSs in data delivery. In this paper, we focus on the TAP association problem for service provisioning in a …
