A chirp-z transform-based synchronizer for power system measurements

2005

In the last few years, increased interest in power and voltage quality has forced international working groups to standardize testing and measurement techniques. IEC 61000-4-30, which defines the characteristics of instrumentation for the measurement of power quality, refers to IEC 61000-4-7 for the evaluation of harmonics and interharmonics. This standard, revised in 2002, requires a synchronous sampling of voltage or current signal, in order to limit errors and to ensure reproducible results even in the presence of nonstationary signals. Therefore, an accurate estimation of the fundamental frequency is required, even in the presence of disturbances. In this paper, an algorithm to detect t…

Stress Detection from Speech Using Spectral Slope Measurements

2018

Automatic detection of emotional stress is an active research domain, which has recently drawn increasing attention, mainly in the fields of computer science, linguistics, and medicine. In this study, stress is automatically detected by employing speech-derived features. Related studies utilize features such as overall intensity, MFCCs, Teager Energy Operator, and pitch. The present study proposes a novel set of features based on the spectral tilt of the glottal source and of the speech signal itself. The proposed features rely on the Probability Density Function of the estimated spectral slopes, and consist of the three most probable slopes from the glottal source, as well as the correspon…

Revisiting “Schumacker”: Source, Residence and Citizenship in the ECJ Case Law on Direct Taxation

2013

ECJ case law on direct taxation has been very important in the development of the international dimension of direct tax systems of EU Member States. Through the application of the non-discrimination principle and the requirements of the fundamental freedoms, some of the basic structures of the implementation of income tax systems have been revised to accommodate to the needs of the single market. However, the requirements of the EU single market are fundamentally incompatible with the assumptions that have served to build the criteria under which modern income tax systems have been developed (worldwide income taxation, residence vs source, unlimited vs limited tax liability, credit vs exemp…

The Constitution of Latvia – A Bridge Between Traditions and Modernity

2019

The Latvian constitutional system is based on the principle of State continuity after the Soviet occupation, and this is reflected in the reinstatement of the 1922 Constitution (Satversme). Unlike other constitutions in the post-communist area, it is characterised as a laconic and predominantly procedural constitution. However, important amendments were introduced in 1996 and 1998, establishing the Constitutional Court and introducing a catalogue of fundamental rights. The constitutional culture has been influenced by German traditions in constitutional jurisprudence, and the adjudication of legislation on substantive grounds has been stringent. This is particularly evident in the annulment…

Political Extremism and Rationality

2002

Political extremism is widely considered to be the product of irrational behavior. Originally published in 2002, the distinguishing feature of this collection by well-known economists and political scientists from North America, Europe and Australia is to propose a variety of explanations which all insist on the rationality of extremism. Contributors use variants of this approach to shed light on subjects such as the conditions under which democratic parties take extremist positions, the relationship between extremism and conformism, the strategies adopted by revolutionary movements, and the reasons why extremism often leads to violence. The authors identify four core issues in the study of…

2015

La comunicación entre tribunales, posibilita la existencia de un intercambio de ideas sobre lo que se debe entender por el contenido de un derecho o de una garantía, con la tendencia de otorgarse mayor protección a favor del ser humano; diálogo que no implica la existencia del predominio de una jurisdicción (internacional o estatal) sobre otra, al contrario con las interrelaciones que se producen entre tribunales, lo que se busca es lograr convergencias interpretativas que propicien un entendimiento común de los derechos y de las garantías. Se ha elegido para trabajar algunas garantías y derechos, como son el plazo razonable, juez natural, libertad de pensamiento-expresión e información- e …

Human Rights in Romanian Courts: A European Perspective?

2016

The perception and application of the European Convention on Human Rights by various national jurisdictions depends fundamentally on the way in which the Convention has been introduced into national law, as well as, in some countries, by how constitutional jurisdictions shaped this relationship. The article examines the reception of the Convention by a few European states, with a special regard on the case of Romania. Romanian courts, including the Constitutional Court and the supreme court, had a hesitant approach of the principle established by 1991 Constitution of the priority of international law of human rights over domestic law. In the context of the diversity of sources of the Europe…
