The ICT Implication on CSR in the Tourism of Emerging Markets
2012
Abstract Tourism has a significant environmental, social and human impact. No other sector provides jobs and ensures wealth across poor countries in the same way as tourism. In the context of sustainable responsible tourism, the concept of Corporate Social Responsibility CSR has gained increased importance: CSR is a company's understanding of the role it plays in society, the environment in which it operates, the values it upholds and its awareness of the intended and unintended consequences of its actions. ICT can create many environmental benefits and there have been several optimistic assessments of the overall relationship between e-business and sustainable development. ICT-based servic…
The Wastewater – A Problem of Integrated Urban Water Management
2013
Abstract In order to live the man uses various generating resources through waste products his work. Use of water resources causes many types of wastewater, depending on the type of household consumption, industrial or city. Integrated management of water resources represents practical ways in which sustainable development is achieved in the field of water, including wastewater management, and is also the responsibility of all interested parties: the state, local communities, users, operators and NGOs waters. The present study shows the role and the importance of integrated management of urban water. The steps to be followed in establishing wastewater management are trying highlighting new …
A Win-Win Scheme for Improving the Environmental Sustainability of University Commuters’ Mobility and Getting Environmental Credits
2022
European Union Member States are called upon to meet internationally proposed environmental goals. This study is based, in particular, on the recommendation of the European Union (EU), which encourages Member States to pursue effective policies to reduce greenhouse gas (GHGs) emissions, including through appropriate changes in the behavioral habits of citizens. In this respect, among the main sectors involved, transport and mobility should certainly be mentioned. National institutions should be adequately involved in order to achieve the objectives set; in this regard, universities must certainly be considered for their educational value. These latter, for instance, could commit to improvin…
Suomalaiset kirkkoherrat Ruotsin valtion rakentajina 1550-luvulta 1610-luvulle
2019
This dissertation and the four separate articles contained therein examine Finnish pastors as builders of the Swedish state from the 1550s to the 1610s. The subject is studied from three perspectives. First, the relationship between the crown and the church (and the pastors) is explored. Second, the study investigates the relationship between the pastors and local communities. The third aspect connects the first two as it sheds light on the pastors’ role as intermediators between local communities and the crown. These perspectives provide the essential frameworks in which state build-ing took place: the centers of the realm, the local communities, and interaction be-tween the two. The sourc…
EMI Filter Re-Design in a SMPS with Inductor in Saturation
2021
This paper analyzes the design issues of the input EMI (Electro-Magnetic Interference) filter's in a switching mode power supply where the power inductor is operated in saturation. Starting with a SMPS equipped with linear inductor, the input filter is firstly designed to comply with Standards. Then, a new inductor with a smaller core size is employed in the same SMPS to exploit saturation. The EMI filter is re-designed, taking into account the increase of EMI introduced by the non-linear operation of the inductor. Finally, the reduction of the inductor's size and cost is compared with the increased size and cost of the EMI filter.
Modeling and simulation of a digital control design approach for power supply systems
2006
Electronic designers need to model and simulate system features as close as possible to its effective behaviour. Moreover, today, electronics systems are often composed of mixed analog and digital components. The increasing complexity has led to the use of different simulation softwares, each one specific for a particular level of abstraction: mathematical, circuital, behavioural, etc. In order to simulate the entire system these softwares should work together: co-simulation is necessary for digitally controlled power electronics systems. In this paper, the modeling of a digitally controlled switching power supply system using MATLAB/Simulink, ALDEC Active-HDL and Powersys PSIM is presented…
Sylviasta, Sylvialle, Sylviana : retoriikka ja merkityksenmuodostus osoitteessa www.sylviaplathforum.com
2016
This study explores the writings of Sylvia Plath Forum, a discussion forum in the Internet that was launched in 1998. Using Norman Fairclough’s critical discourse analysis, Chaïm Perelman’s theory of argumentation, Kenneth Burke’s idea of identification as the basis of rhetoric, and René Girards’s theory of mimetic desire as its framework this study looks into the forum’s meaning-making processes and the ways the author Sylvia Plath (1932-1963) and her readers are represented on the forum. Attention is paid especially to meaning-making practices that are connected with literary studies, feminism, medicalization, and cultic phenomena. Furthermore, cultic discourse and fan discourse are under…
Europe's offshore winds assessed with synthetic aperture radar, ASCAT and WRF
2020
Europe's offshore wind resource mapping is part of the New European Wind Atlas (NEWA) international consortium effort. This study presents the results of analysis of synthetic aperture radar (SAR) ocean wind maps based on Envisat and Sentinel-1 with a brief description of the wind retrieval process and Advanced Scatterometer (ASCAT) ocean wind maps. The wind statistics at 10 and 100 m above mean sea level (a.m.s.l.) height using an extrapolation procedure involving simulated long-term stability over oceans are presented for both SAR and ASCAT. Furthermore, the Weather Research and Forecasting (WRF) offshore wind atlas of NEWA is presented. This has 3 km grid spacing with data …

2019
Abstract. Europe’s offshore wind resource mapping is part of the New European Wind Atlas (NEWA) international consortium effort. This study presents the results of analysis of Synthetic Aperture Radar (SAR) ocean wind maps based on Envisat and Sentinel-1 with a brief description of the wind retrieval process and Advanced SCATterometer (ASCAT) ocean wind maps. The wind statistics at 10m and 100m height using an extrapolation procedure involving simulated long-term stability over oceans is presented for both SAR and ASCAT. Furthermore, the Weather Research and Forecasting (WRF) offshore wind atlas of NEWA is presented. This has 3 km grid resolution with data every 30 minutes during 30 years f…
The workers' strike of 1963 at Tell Chuera: Persistence of colonial practices in Near Eastern archaeology?
2022
This case study appears in: Mays C, Laborie L, Griset P (eds) (2022) Inventing a shared science diplomacy for Europe: Interdisciplinary case studies to think with history. A team of archaeologists from Berlin under the direction of Prof. Anton Moortgat conducted, starting from 1958, excavations at the important ancient urban site of Tell Chuera in northeast Syria. The heterogeneous composition of the Syrian workforce contributed to frequent quarrels and conflicts. In October 1963, one of these conflicts escalated into a 5-day strike, during which the workers also demanded higher wages. After the involvement of local police by the archaeologists, the strike was ended with the threat of bruta…
