Photovoltaic plant array reconfiguration: Design of a new device
2014
An efficient strategy to improve unequally irradiated PV plants performances is based on the reconfiguration of the connections between the modules. In this paper, an algorithm, for this purpose conceived, is presented. Moreover, the design, realization and finally also the set up of a new reconfiguration system device is fully shown and discussed. The algorithm conceived simulates several possible series-parallel connections under varying irradiation conditions, and determines the optimal modules connection in order to get the maximum output power. In this way, the reconfiguration system may set up the reconfiguration strategy. The reconfiguration system prototype set up, basically consist…
The SADC Standby Force and Its Regional Peacekeeping Training Centre: Uncertain Operational Readiness and Future of an Externally Fuelled Brigade
2017
This chapter offers a comprehensive explanation of why and how SADC countries engaged in military integration and put efforts in establishing a regional standby brigade with an associated peacekeeping training centre. This chapter pays special attention to the impact of extra-regional actors and donors’ funding in this regard since the development of the SADC Standby Force occurs at a time when the region lacks an actual external threat. Instead, the African Union, together with the EU, provides financial incentives and thus promotes the build-up of a SADC brigade. The EU’s external influence, however, has been ambivalent insofar as a freezing of donations paralysed the operational capacity…
Improving Maintenance Activities of Machine Tools
2013
The paper follows the current trends in the field of maintenance, proposing approaches that fit in the concept of Total Productive Maintenance (TPM). First it is presented a new proposal for tracking in-service machine tools. This is based on the identification of three operating states: good running condition, state of repair and stationary state. During the stationary state there are differentiated two distinct types of stops: natural stays and unproductive stays (those who often produce considerable losses). Based on the information contained in the records made for tracking the operation of machine tools there are proposed formulas for calculating some operational indicators and practic…
The Directive 2014/95/EU – Is there a “New” Beginning for CSR in Romania?
2017
Abstract The global commandments of sustainable development, assumed and translated by the EU into a series of communications and resolutions, have found themselves a new (and more powerful) expression into the “Directive 2014/95/EU (…) as regards disclosure of non-financial and diversity information by certain large undertakings and groups”; in order to increase the transparency of their sustainability-related actions and results, these companies need to report (starting from 2018, by referring to the financial year 2017) information “relating to, as a minimum, environmental, social and employee matters, respect for human rights, anti-corruption and bribery matters”. As regards the Romania…
Electrocoagulation treatment of peat bog drainage water containing humic substances
2015
Abstract Electrocoagulation (EC) treatment of 100 mg/L synthetic wastewater (SWW) containing humic acids was optimized (achieving 90% CODMn and 80% DOC removal efficiencies), after which real peat bog drainage waters (PBDWs) from three northern Finnish peat bogs were also treated. High pollutant removal efficiencies were achieved: Ptot, TS, and color could be removed completely, while Ntot, CODMn, and DOC/TOC removal efficiencies were in the range of 33–41%, 75–90%, and 62–75%, respectively. Al and Fe performed similarly as the anode material. Large scale experiments (1 m3) using cold (T = 10–11 °C) PBDWs were also conducted successfully, with optimal treatment times of 60–120 min (applying…
Economic Adaptation to Risky Environment in the Late Middle Ages: The Case of the "Accrues" of the Doubs in Chaussin (Jura, France) from c. 1370 to c…
2017
Located along the meanders of the Doubs, the people of Chaussin had to deal with the particular impact of the river on their environment. Due to the impact of the Little Ice Age on water levels in the area, the Doubs sometimes had special floods, which frequently changed its course from the end of the fourteenth century. As a result, some lands were absorbed, and others emerged, which were called the “accrues.” From 1377 the first observation of lost lands appears in the accounts of the castellan, in a petition from landowners who did not want to pay taxes on these fields. More than twenty years later, in the first decade of the fifteenth century, the duke of Burgundy, facing the same situa…
The 4th European Alternative Finance Benchmarking Report
2021
This year’s report is titled ‘Shifting Paradigms’ to, in part, emphasise the continued growth and development of the European Alternative Finance Industry, but also underscore that these patterns of growth can develop and change as the sector continues to develop and mature. Throughout the region, platforms have continued to grow, respond to regulation, and expand operations internationally. In some regions, model prominence has shifted, allowing for others to grow. At times, this has been a response to the development or lack of regulation, or simply a result of competing market forces. Last year’s report, ‘Expanding Horizons’, sought to exemplify the positive developments in European Alte…
Absorption of European Funds by Romania
2014
Abstract The European Union provides financial support to all Member States through structural instruments (Structural Funds) and the Fund for Agriculture. Nationally, each Member State has to set up operational programs (SOP) in accordance with European requirements to access the available money. In the current multiannual financial exercise there are 7 SOP, plus the agriculture program. The absorption level of European funds for the current financial period - 2007-2013 - is low for several reasons: lack of strategic vision for programming development, poor quality of projects, excessive bureaucracy, lack of optimization of financial flows etc. For the upcoming 2014-2020 financial programm…
Operational and financial effectiveness of e-collaboration tools in supply chain integration
2004
This paper develops a comprehensive model of supply chain integration and uses it to analyze and assess the operational and financial effectiveness of different e-collaboration tools at various levels of supply chain integration. This model is also used to evaluate the importance of the sequence in which e-collaboration tools are adopted in supply chain integration. Computational results from a validated system dynamics simulation model with different implementation sequences of e-collaboration tools and different financial scenarios show that local financial constraints can also severely impact operational and financial performance of the entire supply chain.

New Tendencies of Management and Control of Operational Risk in Financial Institutions
2013
Abstract Nowadays, financial institutions highly recognize a great influence of effective risk management on profit abilities. Therefore risk management became an important part of the financial instrument. According to the latest researches, there still remain problems related to the management of various types of risks. For instance, the Basel Committee of the Bank of International Settlements imposes financial institutions for more intensive devoting their attention to operational risk management problems. Due to the increased intensity of performed financial operations, financial institutions became very vulnerable to operational risks. In many cases, the high level of operational risks…
