In the face of energy crisis and environmental pollution problems, all the countries in the world vigorously promote the development of electric vehicles. Electric vehicle charging infrastructure is the necessary infrastructure to the development of electric vehicles. This work has been focused on Electric Vehicles' Charging Stations (CSs) deployment. It has been considered in this study several constraints...
I present a novel definition of services (in particular, public services) which sees each of them as the sum of all activities that realize a public authority's commitment to make available to individuals, businesses, or other public authorities some capabilities intended to answer their needs, giving them some possibilities to control how and when such capabilities should be manifested.
This paper proposes an algorithm for QRS-complex onset detection in single channel ECG signals based on the first differential of the ECG signal and an adaptive baseline estimation. The proposed algorithm was developed and tested using the Physionet QT Database. A 100% detection rate on the onset of the QRS complex, with a mean error±(standard deviation) of −0.48±(11.26) ms was achieved against the...
Analyzing the values of public transport systems energy indicators and metropolitan air pollution together with the branch specific economic forecasts, the authorities and suppliers can estimate future trends. To reduce the urban usage of personal automobiles it is needed to increase the proportion of electric public transport vehicles (Tramways, Trolleys, Electric buses), also it needs to increase...
The article presents core information about National Classification of Economic Activities, National Classification of Product by Economic Activities, National classification of fixed assets. The description of problems and their solutions is presented.
Cloud for Europe (C4E) is a project that aims at creating new Cloud workflows, named Service Flow (SF), for Public Administrations (PAs). These Services must guarantees on one hand to preserve national authorities, and on the other hand to promote efficiency, collaboration and harmonization for European PA bodies. This is possible by means of the creation of a Digital Market where PAs can select the...
European countries start rising the standards regarding the energy performance of buildings by adopting the European Commission's directives with the purpose of driving change in the building sector and promoting a low carbon economy. The energy performance of buildings and the related costs with energy can be reduced from the design phase, by choosing high quality and energy performant materials...
Online education constitutes an important component in the continuous growth / development of higher education and adult education. Its quality largely depends on the design rules and the evaluation standards of the programs as a whole as well as the study courses as component parts. The need to ensure the quality of online courses is a current issue. The paper proposes a system of standards, criteria...
In this study, the mean glanduler dose (MGD) displayed by the mammography system and the MGD calculated according to TS EN 61223-3-2 evaluation and routine testing in medical imaging departments standard have been compared. Measurements were performed in a full-field digital mammography system (FFDM) using polymethyl-methacrylate phantom (PMMA) to simulate breast thicknesses ranging from 20 mm to...
Ethics committee approval processes in development of medical devices begin with request to obtain CE certificate of medical devices that are classified under the Medical Device Directive. In accordance with the Medical Devices Clinical Research Directive, it is necessary to obtain the approval to test on volunteers with medical devices, which is non-CE marked or similar devices that are not found...
A grid-connected inverter with energy storage and active DC-link voltage balancer circuit is presented. The system is implemented with two identical 100kW three-phase converters. The operating limits of the system under asymmetric grid currents with the given hardware architecture are considered and solutions for symmetrisation of the DC-link are proposed.
The subject of this paper is to propose a design method of the EMI filters that allows to minimize the volume of the common-mode inductor with consideration of core saturation issues. Inductor volume depends not only on its inductance value, but also on the relationship between the filter and its environment which can saturate the magnetic material due to many parameters, especially when the filter...
This paper describes the design of a DC grid as a utility grid of a business park. The center of the DC grid is a DC substation. The DC substation is supplied from the MV AC grid. With a transformer and an Active Front-End, the AC voltage of 10 kV is transformed into 750 VDC. At customer side, the 750 VDC is converted to the required DC voltage for his application.
A multiple drives solar-pumping system is presented in this paper. The system is based on a singlestage photovoltaic (PV) topology where an array of solar panels is connected to multiple inverters supplying equal centrifugal pumps. The inverters are operated to obtain maximum power from the PV system and a standard indirect vector control strategy is used to regulate the machines currents. Moreover...
Recently, the demand of the position sensorless control is increasing in motor drive. At low speed range, the saliency-based methods are proposed. In this paper, using the modified symmetrical carrier PWM with switching frequencies up to 16kHz, we achieve to reduce the audible noise that human can be heard.
With increasing competition in the global education sphere, the only way to a decent functioning of the Higher Educational Institutions of Ukraine — to match the high international standards. This cannot be achieved without active international activities aimed at the development of international educational programs. In the Admiral Makarov National University of Shipbuilding, Mykolayiv successfully...
The European Union (EU) Commission has recently introduced a new Project Management methodology named PM squared (PM2) aiming at establishing a common framework for all EU funded projects. PM2 references specifically IPMA-ICB as individual, team and organizational competences are considered key elements for project and business managers. However, the mere reference to IPMA-ICB competences does not...
In standard power cycling tests, forward conduction generates heat in the die and therefore the ther-momechanical stress in the package. In application, however, a significant part of the power losses are switching losses, so that the load current is lower than in standard power cycling test, for an equal temperature swing. A new concept for power cycling tests is presented, which allows the generation...
The problems of implementation and benefits of archival information retrieval system for processing information requests of citizens in the structural units of higher educational establishments are considered. It is proposed to automate the delivery of services in pursuance of biographical and factual queries by archival departments of universities through issuing archival information, excerpts and...
Projects are one of the most important organizational patterns in industry and society. Projects drive change and change takes place in a projectized world. Therefore, project management is a competence field which is required in many areas and on various competence levels. Master education in project management is a special type of delivery for project management competence. It combines a scientific...
