Smart Wireless Sensor Networks and Biometric Authentication for Real Time Traffic Light Junctions Management
2013
The main challenge of intelligent transportation systems (ITS) is to deal with ‘real-time’ information to improve vehicular traffic management. Road data can be processed and used for dynamic traffic light management in order to reduce waiting times in queues. This paper proposes an innovative distributed architecture based on a wireless sensor network (WSN) with a network coordinator providing remote and ubiquitous authentication module for managing unexpected events. The architecture is completed by a dynamic module for street priority management depending on traffic rate. Many experimental trials have been carried out considering three different levels of traffic intensity to prove the e…
Coach-athlete perceived congruence between actual and desired emotions in karate competition and training
2017
Coaches can help athletes regulate emotions but would benefit from tools that help them accurately perceive athletes' emotions. In the present study, we investigated the use of video-recorded performances to compare 3 martial artists' ratings of desired and actual emotions with their coach's ratings. Results show how desired emotions progressively fluctuated throughout competition. Furthermore, desired and actual emotions differed between training and performance contexts. Finally, we report correlations between performance and perceived congruence in desired and actual emotions. Cumulatively, results offer support for the video-assisted recall of emotions as an intervention tool in develop…
Applying the integrated trans-contextual model to mathematics activities in the classroom and homework behavior and attainment
2016
The aim of the present study was to test hypotheses of the trans-contextual model. We predicted relations between perceived autonomy support, autonomous motivation toward mathematics learning activities in an educational context, autonomous motivation toward mathematics homework in an out-of-school context, social-cognitive variables and intentions for future engagement in mathematics homework, and mathematics homework outcomes. Secondary school students completed measures of perceived autonomy support from teachers and autonomous motivation for in-class mathematics activities; measures of autonomous motivation, social-cognitive variables, and intentions for out-of-school mathematics homewo…

Optimisation through offshore – between reality and legality
2021
The study highlights the complete image of the characteristics regarding offshore areas, by taking into account the perspective to deploy new measures of fiscal transparency. The importance of such areas stems from the fact that world economies lose important sums of money, every year by default of taxes. This happens as a consequence of corporative international abuse of fiscal evasion and the relocation of the profit made by big companies. The sums resulted from erosion of national taxation bases, from fiscal evasion and fraud and other infringements connected with fiscal evasion (are often being transferred to offshore companies so that their illegal characteristics gets lost and after t…
Aeolian Remobilisation of the 2011-Cordón Caulle Tephra-Fallout Deposit: Example of an Important Process in the Life Cycle of Volcanic Ash
2020
Although volcanic eruptions represent short periods in the whole history of a volcano, the large amount of loose pyroclastic material produced, combined with aeolian processes, can lead to continuous, long-lasting reworking of volcanic products. Driven by wind, these processes significantly influence the geomorphology and prolong the impacts of eruptions on exposed communities and ecosystems. Since such phenomena are of interest to scientists from a range of disciplines (e.g., volcanology, atmospheric and soil sciences), a well-defined, common nomenclature is necessary to optimise the multidisciplinary characterisation of both processes and deposits. We, therefore, first describe ash wind-r…
Liikenneinfrastruktuurihankkeiden rakentamisaikaiset vaikutukset työllisyyteen
2022
Hankkeen tavoitteena on ollut määrittää tutkittuun tietoon perustuva viitekehys liikenneinfrastruktuurihankkeiden rakentamisaikaisten työllisyysvaikutusten arviointiin. Liikenneinfrastruktuurihankkeen rakentamisaikainen bruttomääräinen vaikutus työllisyyteen muodostuu suorasta työpanostarpeesta työmaalla ja välillisestä työpanostarpeesta. Välillinen työpanostarve taaksepäin syntyy rakentamisen välituotevalmistuksessa ja välillinen työpanostarve eteenpäin palkkatulojen synnyttämän kulutuskysynnän lisäyksen kautta. Nettotyöllisyysvaikutus tarkoittaa työllisyysasteen muutosta taloudessa. Silloin huomioidaan rakentamisesta johtuvan työvoiman kysynnän syrjäytysvaikutus jo olemassa oleviin työpai…
Analiza przestrzennego zróżnicowania zmian w potencjale infrastruktury transportowej w Polsce
2015
Wiele zachodzących zjawisk, ich rozwój czy kierunki zmian, uzależnionych jest od przestrzennych interakcji pomiędzy sąsiadującymi regionami. Model przestrzennej analizy shift-share (SSSA) został wprowadzony do badań przez S. Nazarę i G.J.D. Hewingsa. Przedstawia on przestrzennie zmodyfikowane stopy wzrostu (tempa zmian) poszczególnych wariantów zjawiska przez uwzględnienie temp wzrostu zjawiska w obszarach sąsiadujących. Celem artykułu jest analiza zmian struktury infrastruktury transportowej w województwach Polski w latach 2004 oraz 2014, według rodzajów infrastruktury transportowej z zastosowaniem przestrzennej dynamicznej metody przesunięć udziałów. W opracowaniu dokonano oceny tempa wzr…
LCA of Different Construction Choices for a Double-Track Railway Line for Sustainability Evaluations
2023
The international commitment to achieve carbon neutrality in the next few decades has oriented human activities towards the preservation of natural and non-renewable resources. In this context, a great research effort has been devoted to the search for sustainable solutions for the infrastructure construction sector, based on a thorough assessment of the environmental impact (EI). In this regards, Life Cycle Assessment (LCA) is considered one of the main components of Environmental Impact Assessment (EIA) and, for a comprehensive analysis, all the costs incurred by stakeholders during the useful life of the infrastructure should also be taken into account, applying the Life Cycle Cost (LCC)…
Key challenges facing the European transport labour market
2016
The importance of transport for human development is rather unchallenged. Transport is fundamental for the functioning of markets in general, and the labour market in particular, including the labour it needs for its own functioning. The aim of this article is to identify and assess key challenges in the labour market in the transport sector in the European Union, and present some disputable issues related to activities aiming at dealing with these challenges. First, the direct and indirect importance of transport for the European labour market is discussed. Then, the key challenges in the European labour market are identified. Finally, some potential directions of development and their pos…
