Detecting Power Voltage Dips using Tracking Filters - A Comparison against Kalman
Advances in Electrical and Computer Engineering , 2012, DOI: 10.4316/aece.2012.04012
Abstract: Due of its significant economical impact, Power-Quality (PQ) analysis is an important domain today. Severe voltage distortions affect the consumers and disturb their activity. They may be caused by short circuits (in this case the voltage drops significantly) or by varying loads (with a smaller drop). These two types are the PQ currently issues. Monitoring these phenomena (called dips or sags) require powerful techniques. Digital Signal Processing (DSP) algorithms are currently employed to fulfill this task. Discrete Wavelet Transforms, (and variants), Kalman filters, and S-Transform are currently proposed by researchers to detect voltage dips. This paper introduces and examines a new tool to detect voltage dips: the so-called tracking filters. Discovered and tested during the cold war, they can estimate a parameter of interest one-step-ahead based on the previously observed values. Two filters are implemented. Their performance is assessed by comparison against the Kalman filter?s results.
Systemic Model for Optimal Regulation in Public Service
Ani Matei,Lucica Matei
Theoretical and Applied Economics , 2006,
Abstract: The current paper inscribes within those approaching the issue of public services from the interdisciplinary perspective. Public service development and imposing standards of efficiency and effectiveness, as well as for citizens’ satisfaction bring in front line the systemic modelling and establishing optimal policies for organisation and functioning of public services. The issue under discussion imposes an interface with powerful determinations of social nature. Consequently, the most adequate modelling might be that with a probabilistic and statistic nature. The fundamental idea of this paper, that obviously can be broadly developed, starts with assimilating the way of organisation and functioning of a public service with a waiting thread, to which some hypotheses are associated concerning the order of provision, performance measurement through costs or waiting time in the system etc. We emphasise the openness and dynamics of the public service system, as well as modelling by turning into account the statistic knowledge and researches, and we do not make detailed remarks on the cybernetic characteristics of this system. The optimal adjustment is achieved through analysis on the feedback and its comparison with the current standards or good practices.
Globalization and Europeanization. A Projection on a European Model of Public Administration
Ani Matei,Lucica Matei
Theoretical and Applied Economics , 2008,
Abstract: The specialized studies and literature present moreover and insistently the connection between globalization and Europeanization, more precisely between globalization and a European model of integration, whose features aim to set up a global-type European society. The development of the European model of integration starts with economic elements, it reveals nowadays the Economic and Monetary Union and in perspective it will be structured within a sui generis system of transnational governance. The values of the European model of integration become fundamental values of a social process, with powerful economic and political determinations, aiming the multi-causal interference between individual, community and European construction. This process, remarked increasingly in the specialized literature, being assigned with the name of Europeanization, has got original, functional features in the spectrum of significations of the globalization paradigm. As essential global-type formula, within Europeanization, we shall find models with economic, political or social finality, integrating also a model of administration among the latter ones. When we say administration, we refer to its up dated and adequate contents to the new European developments. This assertion derives from a less economic modality to conceptualize the relationship between globalization and Europeanization, presenting Europeanization more as a political adaptation to globalization and even a political expression of globalization. In this context, the development of a system for European governance on several levels (local, regional, national, intergovernmental and supranational) suggests its evolution towards globalization. In fact, the literature specific for Europeanization asserts the fact that the European model has also features with integrative nature related to the supranational and trans-governmental dimensions, as well as features with normative nature in view of harmonization, also by standards. These assertions, to which we can add also others, are leading to a new model of public administration, whose area overlaps with the space of European Union, incorporating the effects of globalization under its European expression, Europeanization. Consequently, the proposed model, emphasizing the process of European Union construction will comprise transparency, accountability and participation of the interested parties to public decision. The new public administration aims to use efficiently the resources in order to create favourable conditions for its citizens to become more competitive on
Systemic Models of Local Development
Ani Matei,Lucica Matei
Theoretical and Applied Economics , 2007,
Abstract: The paper approaches in a systemic manner the topic of local development, attempting, on one hand, to turn into account the previous contributions from the specialized literature and, on the other hand, to emphasize the specific mechanisms, describing and modelling the behavior of a local development system, underlining its feedback. The basic hypotheses of a systemic model for local development are synthesized in emphasizing three main subsystems, representing three levels of public management. At the same time, a local development system is composed by the convergence of two cybernetic systems, namely an administrative and an economic one, each with specific missions. Consequently, the paper aims a model for an economic-administrative system of local development (SEADL), whose self-regulation mechanisms are based on qualitative assessments, concerning the relevance or usefulness/sustainability of a local development policy as well as quantitative assessments, referring to efficiency or effectiveness. In the end of the paper a case study is presented in details, being achieved in Braila Municipality, valorising SEADL feedback, using assessments based on production factors or Keynesian approaches. The study represents only a framework, a general one for approaching a complex topic, such as local development, and it may be obviously completed and improved.
“Globalisation of Corruption” and Development of the Binom “Corruption – Public Integrity” in the Context of Romania Integration into the European Union
Lucica Matei,Ani Matei
Theoretical and Applied Economics , 2008,
Abstract: In the context of globalisation, the issue of corruption acquires specificity, deriving, on one hand, from the diversification of the modalities to corrupt or to be corrupted and, on the other hand, from multiplication of the means to fight against this phenomenon. The binom corruption-public integrity becomes a motto of the speeches held by politicians and generally those invested with leadership functions by the society. It is unanimously recognised the fact that a relevant indicator of an ethical leadership refers to the level and social perception of corruption. Speaking about “the devastating effect of globalisation on the developing countries and especially on poor populations”, J. Stiglitz (2002) allocates large spaces to corruption, referring to “the cases of foreign investments”, “capitalism based on favouritisms and mafiatyped connection” or “privatisation”. Including integration into the European Union as a form for expressing globalisation in the European area, it is worth to analyse some consequences of this process on the evolution of the binom corruption-public integrity. When we speak about “globalisation of corruption” we refer to some conclusions emphasized by the specialized literature and studies. Without trying to make a hierarchy of those conclusions, we shall refer, first of all, to its multiple facets that, by chance or not, are overlapping the modalities for expressing globalisation on economic, cultural, political level and as well as on the public sector reform. If we analyse an outstanding paper about corruption of Rose-Ackerman (1999), we shall find out that three from the four basic chapters focus on approaching corruption as an “economic, cultural or political problem”(1).In the context of globalisation, the issue of corruption acquires specificity, deriving, on one hand, from the diversification of the modalities to corrupt or to be corrupted and, on the other hand, from multiplication of the means to fight against this phenomenon. The binom corruption-public integrity becomes a motto of the speeches held by politicians and generally those invested with leadership functions by the society.

Transylvanian Review of Administrative Sciences , 2011,
Abstract: At the beginning of the 21st century, the European Union (EU) governance and administration are undergoing some significant transformations, not without obstacles, from concept to reality, revealing characteristics that aim both the European and national elements in a permanent interpenetration, whose complexity is superior to other processes and phenomena specific for the construction of a United Europe. The major objective of the current paper is to substantiate and describe systemically the process of affirmation and transformation of the EU administration as a core pillar of European governance. A doctrinal overview on the debated topic reveals an atypical concept in terms of the traditional approach in administrative sciences, thus leading in the specialized studies to controversies going to the conceptual negation of the EU administration. This time, the reality of EU construction anticipates traditional theories and doctrines, imposing even a change of vision, getting closer to the modern theories of public management and administration. The EU administration has developed simultaneously with the construction of the United Europe on a distinct area that overlaps with the EU area in its various enlargement stages. In a regulatory perspective, the EU administration has benefited due to the constitutive treaties, from a contextual ground containing relatively few direct and explicit assertions, but which valorize the European traditions and culture, mainly in the Member States, integrating creatively the international developments of public management.In a developing relation, we witness a permanent adaptation of the EU administration to the needs arising from the achievement of the EU objectives. The attempt to institute an ‘EU Constitution’ got the doctrinal approach of the EU administration closer to the traditional approach specific for the European legal systems. The failure of that activity has created a new impetus to a different approach encompassing even features of a significant reform expressed in the Lisbon Treaty that entered into force on December 1st 2009. Taking into consideration the background of the European integration, the studies and researches highlight that the main processes of the EU administration construction consist of Europeanization, administrative convergence and dynamics. In a systemic approach they become mechanisms of adjustment and self-adjustment in a social dynamic system, with multi poles and mixed architecture, such as that of the EU administration
Transylvanian Review of Administrative Sciences , 2009,
Abstract: The paper aims to evaluate how the anticorruption strategies contribute towards minimizing the corruption phenomenon in the public organizations, with special reference to the strategies used in the Romanian public administration and health system. Based on some essential features stated by Banfield (1975) with regard to the capacity of public organizations to minimize corruption inside the organizations, the authors conducted two parallel researches in the public administration system and in the health system in Romania. Thus, the researches revealed a paradox in the finality of the analyzed public organizations, which focus either exclusively on ethical behavior or on other objectives such as: effectiveness, flexibility, dynamics etc. In the context of some very interesting studies, such as those conducted by Rose-Ackerman (1975, 1999), the premises of our research are based on the idea that “the anticorruption strategies should orient firstly towards the improvement of the economic, technical and operational efficiency” of the public organization. Therefore, the authors speak about “optimal” level of corruption rather than “zero” level of corruption. The authors justify this fact through the costs of supporting the anticorruption strategies, their direct impact on organizational effectiveness and performance.
Public Integrity and Performance of Governance. A Comparative Study for South-Eastern Europe
Ani Matei,Lucica Matei
Theoretical and Applied Economics , 2009,
Abstract: The studies concerning the impact of corruption on the effectiveness of governance are numerous, valorising profound approaches, based on criteria and standards related to good governance, organizational behaviour.The concepts and mechanisms specific for econometrics and statistics provide the quantitative support for qualitative analyses, substantiating public policies, in view to assure effectiveness in performance measurement.For all South-Eastern European countries, the level of development and social organization determines specific ethical behaviours. In this context, the current paper aims a comparative economic and social evaluation of the correlations between corruption, performance and economic freedom in South-Eastern European countries, including Romania.The working hypotheses turn into consideration the following issues:- corruption holds national specific character and the statistic, econometric or sociologic analyses reveal that it is stable during the time;- an effective governance leads to increasing the citizens’ welfare;- if a country is poor and the economic freedom is reduced than the bureaucratic and political system tends to be more corrupted;- the perspective of accession into the EU has led to the perception concerning the reduction of the corruption level.The above hypotheses will be completed and we shall achieve comparative analyses, relevant for the group of South-Eastern European countries. The above quantitative analyses will use both own results of the researches carried out by the authors and public results of World Bank, Transparency International and Heritage Foundation, as well as results of authorities responsible for national statistics. The comparative research is achieved on a 10 years period, comprising also the moment of accession into the European Union for some states.
Economics of Corruption. The Equilibrium, Political and Social Determinations
Ani Matei,Lucica Matei
Theoretical and Applied Economics , 2006,
Abstract: he paper starts, on one hand, from the statement unanimously accepted that corruption exists in all societies, and on the other hand, from the preoccupations existent in the international literature about proving scientifically the models of analysis of corruption and determining on this basis some relevant corruption indicators. In essence, the paper focuses on the sphere of the theoretical preoccupations, trying to offer an interpretation based on extended economic and social analysis, mechanisms that structure and describe a genuine system of the corruption actions. Most frequently, corruption occurs in the common public-private activities and it has determinations in the central or local governmental structures. The binom corruption - anticorruption has its origin in distinct social actions, with different actors and different logic constructions, aiming to destroy or strengthen the systems of public integrity. In the context of the theoretical approaches, this paper presents for exemplification relevant aspects concerning social perception on corruption and comparisons of the situations in Romania with those in Central and Eastern Europe or the states newly admitted into the European Union. The paper aims a new way for approaching the nonlinear relationship between political stability/instability and corruption, as well as its economic effects. An extended space is granted to the model of corruption market and conditions of balance within its framework. As it is conceived, the paper enables the enlargement of the theoretical and empirical researches concerning the corruption phenomena.
Assessing the Anti-corruption Strategies: Theoretical and Empirical Models
Ani Matei,Lucica Matei
Journal of Management and Strategy , 2011, DOI: 10.5430/jms.v2n1p23
Abstract: The preoccupations about conceiving and promoting efficient anti-corruption strategies exist in most states, especially in the developing countries. The opportunity of such strategies derives from the direct link, demonstrated theoretically and empirically, between the effects of the anti-corruption strategies and government performance, translated both in the economic and social results and living standard, welfare etc. In the last decades, the transnational actors – UN, World Bank, OECD, EU etc. - have affirmed as promoters of own anti-corruption strategies, directing the states’ efforts, conferring adequate levels of relevance, effectiveness, efficiency or sustainability. The South-Eastern European states incorporate own anti-corruption strategies in the framework of general strategies, aiming the government reform in the context of the European integration process. Strengthening the public integrity, reducing corruption, developing a genuine climate of economic freedom become important objectives concerning the impact on government performance. The paper incorporates briefly the main characteristics of anti-corruption strategies, developed by transnational actors and it aims to shape theoretical and empirical frameworks for the assessment of anti-corruption strategies. The focus on some South-Eastern European states has a demonstrative character, as the presented analyses may be extended to various geo-political areas.
