Régi és új tendenciák a büntetőjogban és a büntetőjog-tudományban : Gondolatok Nagy Ferenc monográfiájáról, illetve annak ürügyén
"Nagy Ferenc szegedi professzor új monográfiája áttekinti a büntetőjog tudományának fejlődését, külön figyelmet szentelve napjaink irányzataira.
E hézagpótló könyv ismertetése mellett a recenzensnek módja van kifejtenie saját - a szerzőével nagyrészt azonos - álláspontját büntetőjogunk fejlődésének aktuális kérdéseiről, a hagyományos dogmatika mind szembetűnőbb eróziójáról.
Realization Theory for LPV State-Space Representations with Affine Dependence
In this paper we present a Kalman-style realization theory for linear
parameter-varying state-space representations whose matrices depend on the
scheduling variables in an affine way (abbreviated as LPV-SSA representations).
We deal both with the discrete-time and the continuous-time cases. We show that
such a LPV-SSA representation is a minimal (in the sense of having the least
number of state-variables) representation of its input-output function, if and
only if it is observable and span-reachable. We show that any two minimal
LPV-SSA representations of the same input-output function are related by a
linear isomorphism, and the isomorphism does not depend on the scheduling
variable.We show that an input-output function can be represented by a LPV-SSA
representation if and only if the Hankel-matrix of the input-output function
has a finite rank. In fact, the rank of the Hankel-matrix gives the dimension
of a minimal LPV-SSA representation. Moreover, we can formulate a counterpart
of partial realization theory for LPV-SSA representation and prove correctness
of the Kalman-Ho algorithm. These results thus represent the basis of systems
theory for LPV-SSA representation.Comment: The main difference with respect to the previous version is as

A Few Remarks About the Criminal Corruption in Hungary
Whenever we type the word „corruption” in any of the internet-based search programs, it gives nearly 20 million results, and the fact is, that hundreds of international conferences focus on the so-called “today’s plague” phenomenon every year.
Nowadays it is hard to say anything new about one of our greatest common enemy to date, that spreads across the globe, corruption.
The roots of abuse and misuse carried out to reach individual goals, backed by rights delegated by the community, date back to thousands of years
Towards Efficient Maximum Likelihood Estimation of LPV-SS Models
How to efficiently identify multiple-input multiple-output (MIMO) linear
parameter-varying (LPV) discrete-time state-space (SS) models with affine
dependence on the scheduling variable still remains an open question, as
identification methods proposed in the literature suffer heavily from the curse
of dimensionality and/or depend on over-restrictive approximations of the
measured signal behaviors. However, obtaining an SS model of the targeted
system is crucial for many LPV control synthesis methods, as these synthesis
tools are almost exclusively formulated for the aforementioned representation
of the system dynamics. Therefore, in this paper, we tackle the problem by
combining state-of-the-art LPV input-output (IO) identification methods with an
LPV-IO to LPV-SS realization scheme and a maximum likelihood refinement step.
The resulting modular LPV-SS identification approach achieves statical
efficiency with a relatively low computational load. The method contains the
following three steps: 1) estimation of the Markov coefficient sequence of the
underlying system using correlation analysis or Bayesian impulse response
estimation, then 2) LPV-SS realization of the estimated coefficients by using a
basis reduced Ho-Kalman method, and 3) refinement of the LPV-SS model estimate
from a maximum-likelihood point of view by a gradient-based or an
expectation-maximization optimization methodology. The effectiveness of the
full identification scheme is demonstrated by a Monte Carlo study where our
proposed method is compared to existing schemes for identifying a MIMO LPV
system

Corruption manual for beginners: "Corruption techniques" in public procurement with examples from Hungary
This paper develops 30 novel quantitative indicators of grand corruption that operationalize
20 distinct techniques of corruption in the context of public procurement. Each indicator
rests on a thorough qualitative understanding of rent extraction from public contracts by
corrupt networks as evidenced by academic literature, interviews and media content
analysis. Feasibility and usefulness of the proposed indicators are demonstrated using
micro-level public procurement data from Hungary in 2009-2012. While the prime value of
this broad set of indicators is the possibility of combining them into a robust composite
indicator of high-level corruption, the high degree of detail also reveals that many
regulatory interventions have succeeded in changing the form of corruption, but not its
overall incidence
