Un experiment asupra regulilor de vot

In this article we examine the consequences of changing voting woes in experimental conditions. In this case we test two theses: a) different voting rules lead to different results and b) to what extent strategic voting is present in the experiment. The experiment took place during the course of Election Analysis, Faculty of Political Science, SNSPA Bucharest. The two voting procedures used in the experiment were approval voting and Borda vote

Direct neural-network hardware-implementation algorithm

An algorithm for compact neural network hardware implementation is presented, which exploits special properties of the Boolean functions describing the operation of artificial neurones with step activation function. The algorithm contains three steps: ANN mathematical model digitisation, conversion of the digitised model into a logic gate structure, and hardware optimisation by elimination of redundant logic gates. A set of C++ programs automates algorithm implementation, generating optimised VHDL code. This strategy bridges the gap between ANN design software and hardware design packages (Xilinx). Although the method is directly applicable only to neurones with step activation functions, it can be extended to sigmoidal functions

Effect of Economic, Institutional and Cultural Factors on the Implementation of EU Energy Policies

This study assesses the effect of economic, institutional, and cultural factors on green energy production. The present research considers only sources for which the European Union cofinances investment in production capacity; thus, we exclude hydroelectric power. The economic determinants are internal consumption and national income, the institutional ones are the Worldwide Governance Indicators, and the cultural ones are the national cultural indicators of Hofstede. Data comprise the European Union countries for the 2007-2015 period, the longest time period in which the structure of the Union has remained mostly unchanged. We employ random effects panel data models and hierarchical clustering. Our main results emphasise the significant impact of internal energy consumption per capita, government effectiveness, rule of law, control of corruption, power distance, and uncertainty avoidance. The multidimensional hierarchical clustering points out three behavioural groups based on these variables. Two of them are quite homogeneous with respect to the geographical distribution of the countries on the European continent

Analysis of Fiscality and Economic Growth at EU Level

Purpose/objectives: What this article proposes is to make a presentation as clear and current as possible of the member states' taxation, direct and indirect taxation being the main categories to which we refer. The choice of the theme was motivated by our interest in discovering the effects of some decisions taken at the European level. It is desired to discover the way and the impact in which taxation influences economic growth in the European community. Design/methodology: Mix research technique has been used. While qualitative research entails in-depth literature readings and reports, quantitative analysis entails presenting data via graphs and tables. Findings: Taxation was and will remain a main component in the general economy that influences the good functioning of a system. Its effectiveness is conditioned by the legal regulations that each state designs individually, but not without the influence of the communities of which it is a part. For example, Romania was conditioned upon its entry into the European Union to modify its laws in order to be at the same level as the states in the Union. It is a laborious process that takes a long time and is constantly changing and improving. The process of designing and implementing these programs is tried to be carried out as easily as possible for each individual state, being individualized by economy, regional power, global impact, etc. The progress of each country entered in this sense is very important and is constantly monitored, and periodic reporting is very useful. Originality/value: The work is an original research work conducted by the researchers. The findings will add to the body of knowledge on the area of research funding in Romania. Possible practical implications: The completed project is addressed to those people who are interested in the fiscal side of an economy, especially understanding the process of economic growth, how difficult it is to reach a favorable situation at such a high level.. It can also represent a starting point for bachelor's, master's level studies, in order to broaden general knowledge, or even in-depth study for a final paper

Adequate early treatment positively influenced the evolution of the disease and favored the patient’s prognosis

Amyloid hydrogen bonding polymorphism evaluated by15N{17O}REAPDOR solid-state NMR and ultra-high resolution fourier transform ion cyclotron resonance mass spectrometry

A combined approach, using Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) and solid-state NMR (Nuclear Magnetic Resonance), shows a high degree of polymorphism exhibited by Aβ species in forming hydrogen-bonded networks. Two Alzheimer’s Aβ peptides, Ac-Aβ16–22-NH2 and Aβ11–25, selectively labeled with 17O and 15N at specific amino acid residues were investigated. The total amount of peptides labeled with 17O as measured by FTICR-MS enabled the interpretation of dephasing observed in 15N{17O}REAPDOR solid-state NMR experiments. Specifically, about one-third of the Aβ peptides were found to be involved in the formation of a specific >C═17O···H–15N hydrogen bond with their neighbor peptide molecules, and we hypothesize that the rest of the molecules undergo ± n off-registry shifts in their hydrogen bonding networks
