A Novel Model for E-Business and E-Government Processes on Social Media
2013
Abstract The global digital economy tends to grow up through the adoption of key technologies, mobility, cloud computing, data mining, artificial intelligence or the extension of social environments. These influences turns up the economy and give rise to new tendencies for obtaining the value. The e-business and e-government strategy is not an easy to organize, although in terms of a fundamental strategy of e-business will be led by the super-expansion of the market. For this reason, the aim of this study is to demonstrate the implications that social media has in the development of electronic business (e-business) and to provide, through a mode, a viable solution to companies or even Gover…
Culture – A Value of Public Management
2014
Abstract Culture has become the most dynamic component of our civilization. This dynamism, the search for new forms and means of expression, is the result as well as the engine of the “knowledge society”. Any analytical approach of cultural policies of European countries must be based on recognition and measurement of changes in political, economic and social field that brought the end of the second millennium: globalization and European integration.
The Value of Brand Equity
2013
Abstract This paper aims to be a brief presentation of brand equity as a provider of strategic advantages for companies that own brands. Successful management of a brand must be focused on values capitalization so that these attributes could represent a natural extension of general perception. The stated goal of any brand manager is to strengthen the brand values so that they may be easily recognizable and identifiable to the public.
Analyzing Consumer Engagement Programs from the Perspective of a Qualitative Research of Marketing Executives
2014
Abstract Consumer engagement is a multidimensional concept comprising cognitive, emotional, and/or behavioral dimensions, and plays a central role in the process of developing long lasting relationships with mutual benefits for companies and their customers. In the Internet-context, consumers can co-create experiences and personal value through engagement in activities that involve interactivity and networking with companies in the online environment. In this technology-driven framework, consumer engagement programs can offer a valuable opportunities for companies that are active in an online setting. The present research implies a qualitative study conducted using interviews with marketing…
Risks Management Profile in Local Public Services Administration
2015
Abstract This paper aims improving local public services practices, at least, for our national local communities’ administration. Such possibilities may arise by case study regarding delegated management of a public entity charged with central heating public service, turned in private company. Paper treats local public finance and reveals the risks of defection management and even fraud risk by periodical re-negotiating of significant contracts with related parties and internal controls deficiency. The moral value of case study is economics considerations over legal considerations prevalence by applying principle of correlating demands with resources, not upside-down. Romanian local public …

Reliability of PEA Measurement in Presence of an Air Void Defect
2020
This paper deals with the reliability of the Pulsed Electro-Acoustic (PEA) technique in the case of a specimen containing an air layer. The first approach to this study has been proposed by the authors in previously published works. In these papers, the mathematical description, the PEA cell simulation model, and some experimental tests have been reported. In this work, a more accurate description of the acoustic wave behavior within the PEA cell and specimen with and without an air layer is given. Moreover, the comparison between simulation and experimental tests for both cases (specimen with and without air layer) allowed the validation of the previously developed PEA cell simulation mode…
Trace compounds affecting biogas energy utilisation – A review
2011
Abstract This paper investigates the trace compounds affecting energy utilisation in biogas that come from different production sites. With biogas being more widely used in different energy applications more interest has arisen for the specific composition of biogas. In traditional energy applications, methane and hydrogen sulphide contents have had the most influence when energy utilisation application has been considered. With more advanced processes also the quantity and quality of trace compounds is more important. In regards to trace compounds, it was found that the concentrations and the variations of volatile organic compounds (VOCs) can be high in different landfills, especially, wi…
NO formation tendency characterization for solid fuels in fluidized beds
2013
Abstract Usually the standard fuel analysis is not enough to allow for accurate NO emission predictions in large scale fluidized bed combustion. This paper presents NO formation tendency characterization results from novel laboratory measurements in a small-scale fluidized bed combustor. With the special two-stage oxidation method it is possible to eliminate the observed problems of unstable test conditions during rapid pyrolysis of high-volatile fuels in batch combustion. Experimental results of the conversion of fuel nitrogen to NO are presented for wide range of fuels, ranging from coal-type fuels to peat, biomasses and wastes. A NO formation tendency database is formed based on the resu…
A Preliminary Energy Assessment to Improve the Energy Sustainability in the Small Islands of the Mediterranean Sea
2020
Power plants supplied by renewable energy sources are expanding around the world, in order to reduce the carbon dioxide emissions, limit the global warming and improve the energy sustainability. Despite the relevant achieved results, small islands are heavily reliant on fossil fuels. In this context, renewable energy sources are available but practically unused, due to landscape and economic constraints. This condition is quite common in the Mediterranean Sea. These islands are normally fed by a stand-alone electrical grid and a power plant, equipped with diesel engines. In order to improve the sustainability of the energy sector, the paper considers the case study of Ustica, a small Italia…
