The legal consequences of supporting candidates on recommendation sheets in an illegal way

Klára Nagy

Publication Name: Acta Juridica Hungarica

Publication Date: 2015-03-01

Volume: 56

Issue: 1

Page Range: 30-38

Description:

In 2014 there were three elections in Hungary: the election of Members of Parliaments, the election of members of the European Parliament, furthermore, the elections of representatives and mayors of municipalities and of representatives of national minority local self-governments. The Hungarian Parliament passed a new act on electoral procedure in 2013 and we have had a new Criminal Code since 2012. This study examines a new legal institution, the recommendation sheets, which raise many questions, including criminal liability. The main theme of the study is the misuses related to recommendation sheets.

Computational complexity in test-generation algorithms

Jozsef Sziray

Publication Name: Proceedings of 2014 9th International Design and Test Symposium Idt 2014

Publication Date: 2015-02-10

Volume: Unknown

Issue: Unknown

Page Range: 124-129

Description:

The paper is concerned with analyzing and comparing two exact algorithms from the viewpoint of computational complexity. Both serve for calculating fault-detection tests of digital circuits. The first one is the so-called composite justification, and the second is the D-algorithm. The analysis will be performed on combinational logic networks at the gate level. Here single and multiple stuck-at logic faults will be considered. As a result, it is pointed out that the composite justification requires significantly less computational step than the D-algorithm and its modifications. The difference manifests itself especially in terms of multiple faults. From this fact it has been conjectured that possibly no other algorithm is available in this field with fewer computational steps. If the claim holds, then it follows directly that the test-calculation problem is of exponential time, and so are all the other NP-complete problems. It may also be expected that the minimal complexity of composite justification applies to any modeling level (either low or high) of digital circuits, just like the exponential-time solution.

Description:

In this paper, a spiking neural network based emotional model is proposed for a smart phone based robot partner. Since smart phone has limited computational power compared to personal computers, a simple spike response model is applied for the neurons in the neural network. The network has three layers following the concept of emotion, feeling, and mood. The perceptual input stimulates the neurons in the first, emotion layer. Weights adjustment is also proposed for the interconnected neurons in the feeling layer and between the feeling and mood layer based on Hebbian learning. Experiments are presented to validate the proposed method. Based on the emotional model, the output action such as gestural and facial expressions for the robot is calculated.

Issue: Unknown

Page Range: 787-795

Description:

The authors will introduce Gyor as a significant member and centre both of this region and the Central European automotive industrial concentration. The study gives an overview of the emergence of the special Triple Helix Model in the analysed Hungarian town. Based on the results of the research programme 'Gyor Regional Vehicle Industrial District as a New Direction and Investment of Regional Development' (TÁMOP-4.2.2.A-11/1/KONV-2012-0010) completed in 2014, the authors will present the "Model of Gyor". The paper outlines the most significant theoretical and empirical results of the research which serves further development prospects, paths and examples to other Hungarian towns or to towns with similar industrial background around the world. The model represents the urban network structure as a 'living system' of Gyor that includes the university, the automotive industry and related innovative companies like Audi and the town (local government) as a coordinating factor.

Physical and numerical modelling of climate-change influenced, poorly-compacted glacial till embankments

Publication Date: 2015-01-01

Volume: 7

Issue:

Page Range: 3911-3916

Description:

Cutting and embankment slopes are subject to seasonally changing hydraulic boundary conditions. This results in repeated wetting and drying of the soil mass, which in certain combinations of slope geometry, soil type, fabric feared to induce significant swellshrink cycles raising serviceability issues and possibly lead to extensive down-slope displacements. Since the response of infrastructure embankments is particularly relevant in light of the current global climate change, numerical and centrifuge model studies focusing on saturated overconsolidated clay earthworks - mainly representing cutting slopes - have been carried out to investigate the above mentioned effects. Some of these tests suggested that, even a slope failure may be triggered after a number of cycles due to softening of the soil. More recent centrifuge model test results of compacted glacial till embankment with more shallow slopes reviled that the observed behaviour for heavily overconsolidated steep slopes representing cutting like conditions should not be directly adopted when investigating the behaviour of poorly compacted embankments with dominant inter-granular porosity influencing both hydraulic and mechanical response of the structure. The paper thus aims to improve the understanding by undertaking series of numerical modelling and analysis using Plaxis. The input parameters for the implemented advanced hypoplastic constitutive model that could capture the small-strain nonlinearity have been determined based on earlier and more recent advanced element test results. The boundary conditions were set to match those from the centrifuge tests, and finally the model has been refined to reproduce the experienced hydraulic and mechanical behaviour.

'Lovers of Beauty': The oeuvres of george santayana, fred holland day and edward perry warren as exemplifications of aesthetics of existence influenced by the platonic eros

Nóra Horváth

Publication Name: Brno Studies in English

Publication Date: 2015-01-01

Volume: 41

Issue: 2

Page Range: 5-21

Description:

My theory is about the lovers of beauty who tried to aestheticize their existences in different ways, but with the same goal: To make life into an oeuvre. George Santayana created an aesthetic ontology, Fred Holland Day made a photo composition (Beauty is Truth), which is the essence of his aesthetics of existence, and Edward Perry Warren spiritualized the Male ideal shaped through the praising of the Uranian Eros. They used the Hellenic idea as a life-giving energy, they re-eroticised the philosophical thoughts about self-creation and the aesthetic way of life. The serious questions of private perfection and self-creation can be the basis of an ethics of personality. According to Agnes Heller it is always the ethics of one person. We have to illustrate it, if we want to speak about it. So, we have to examine one paradigmatic case to illustrate the essence of it.

A new state reduction approach for fuzzy cognitive map with case studies for waste management systems

Miklós F. Hatwágner Peter Foldesi Adrienn Buruzs L. T. Kóczy

Publication Name: Advances in Intelligent Systems and Computing

Publication Date: 2015-01-01

Volume: 331

Issue: Unknown

Page Range: 119-127

Description:

The authors have investigated the sustainability of Integrated Waste Management Systems (IWMS). These systems were modeled by Fuzzy Cognitive Maps (FCM), which are known as adequate fuzzy-neural network type models for multi-component systems with a stable state. The FCM model was designed of thirty-three factors to describe the real world processes of IWMS in as much detailed and as much accurately as possible. Although, this detailed model meets the requirements of accuracy, the presentation and explanation of such a complex model is difficult due to its size.While there is a general consensus in the literature about a very much simplified model of IWMSs, detailed investigation lead to the assumption that a much more complex model with considerably more factors (components) would more adequately simulate the rather complex real life behavior of the IWMS.As the starting point we used the thirty-three component model based on the consensus of a workshop of experts coming from all areas of the IWMS (operation, regulation, management, etc.) and the set goal was to find the most accurate real model that could be obtained by analyzing and properly reducing this – very likely too much detailed, or atomized – model.In this paper, a new state reduction approach with three different metrics is presented. The practical aspects of the results gained by these methods are evaluated.

Municipal bonds in Hungary: Constraints and challenges

Kovács Gábor

Publication Name: Springer Geography

Publication Date: 2015-01-01

Volume: Unknown

Issue: Unknown

Page Range: 257-274

Description:

After the collapse of communist rule, Hungarian local governments had to meet new challenges and expectations. Due to the decentralisation process, local governments’ revenues decreased significantly in the last two decades, while the level and scope of services provided decreased less rapidly, if at all. Consequently, local governments, short of resources, had to develop their ability to raise funds needed to meet local spending needs. This study examines the general theoretical framework of municipal borrowing, comparing the economic and social advantages of bank loans versus municipal bonds. It also evaluates the role of the national government’s central administration in regulating local authority indebtedness. It then presents and analyses the characteristics of Hungarian local government bond financing, assessing the appropriateness of bonds as a local government fundraising tool. The indebtedness of Hungarian local authorities has increased drastically since 2006, mainly through bond financing. A substantial proportion of these bonds were issued in foreign currencies because interest rates were lower. The subsequent economic downturn and devaluation of the Hungarian forint has left many local governments worse off because their indebtedness has increased in forint terms. Bond financing is often considered simply an alternative form of borrowing, and Hungarian local governments do not fully benefit from the flexible features offered by bonds. In today’s Hungary, bond financing offers opportunities to broaden local government financial freedom and reduce the financial risk related to borrowing, but they also pose risks, particularly in the absence of local expertise. Regulation of local government borrowing is still mainly based on the coercive effect of a credit limit. This is a one-sided approach to the problem, and current Hungarian regulations fail to meet the expectations of the most important players in the European capital market, namely, institutional investors. New regulations are needed which can enhance the beneficial characteristics of bonds, while preserving the security they provide to local governments and prospective investors.
