Combining Public Key Encryption with Schnorr Digital Signature  [PDF]
Laura Savu
Journal of Software Engineering and Applications (JSEA) , 2012, DOI: 10.4236/jsea.2012.52016
Abstract: This article presents a new signcryption scheme which is based on the Schnorr digital signature algorithm. The new scheme represents my personal contribution to signcryption area. I have implemented the algorithm in a program and here are provided the steps of the algorithm, the results and some examples. The paper also contains the presentation of the original Signcryption scheme, based on ElGamal digital signature and discusses the practical applications of Signcryption in real life. The purpose of the study is to combine the public key encryption with Schnorr digital signature in order to obtain less computational and communicational costs. Signcryption primitive is a better approach then Encrypt-then-Sign or Sign-then-Encrypt methods regarding the costs. All these algorithms offer the possibility to transmit a message over an insecure channel providing both authenticity and confidentiality.

Hydrodynamic scaling limit of continuum solid-on-solid model
Anamaria Savu
Journal of Applied Mathematics , 2006, DOI: 10.1155/jam/2006/69101
Abstract: A fourth-order nonlinear evolution equation is derived from a microscopic model for surface diffusion, namely, the continuum solid-on-solid model. We use the method developed by Varadhan for the computation of the hydrodynamic scaling limit of nongradient models. What distinguishes our model from other models discussed so far is the presence of two conservation laws for the dynamics in a nonperiodic box and the complex dynamics that is not nearest-neighbor interaction. Along the way, a few steps have to be adapted to our new context. As a byproduct of our main result, we also derive the hydrodynamic scaling limit of a perturbation of the continuum solid-on-solid model, a model that incorporates both surface diffusion and surface electromigration.
ECONOMIC RIGHTS OF THE NEIGHBORING RIGHTS OWNERS PERFORMERS’ RIGHTS MANAGEMENT
MARIANA SAVU
Challenges of the Knowledge Society , 2012,
Abstract: The scientific research theme aims to deepen a topical issue, i.e. to examine the legal requirements of performers’ rights from Romania, by collective management, to do a critical analysis of the regulation in our country and to contribute thereby to the correction of the law, to its harmonization with the EU countries. Intellectual creation has some amazing features: it is invisible, it can be passed across borders, it can be multiplied to infinity and its value increases steadily over time. Any country that cares about its traditions and seeks to make progress in the field of culture, of science and education, must recognize, encourage and protect intellectual creation. The copyright neighboring rights or "les droits voisins" as they were called in doctrine and jurisprudence, have been regulated for the first time in the Romanian law by the Law no.8 /1996 on copyright and neighboring rights. The neighboring rights are intellectual property rights, other than the copyright, granted to performers for their own performances or executions, to sound recordings producers and audiovisual recordings producers for their own recordings, and to broadcasting organizations (radio and television) for their own transmissions and program services. Performers’ rights can be managed mandatory or optionally by the collective management societies. The collective management of copyright and neighboring rights is a necessary step for implementation of certain rights in comparison with various ways of exploitation. Since the beginning, some of performers’ economic rights proved difficult to assess individually. The technical progress and widespread mass exploitation have made individual control virtually impossible. Collective management primarily involves the collection of remuneration payable by users/importers and its distribution to those entitled to it, proportional to the actual use of each repertory, within 6 months from collection date.
HARMONIZING PHASE OF THE ROMANIAN LEGISLATION REGARDING PERFORMERS’ RELATED RIGHTS
MARIANA SAVU
Challenges of the Knowledge Society , 2013,
Abstract: The Copyright System as established by the Bern Convention for the Protection of Literary and Artistic Works1, did not provide the necessary protection to those “parties” involved in bringing the work to the public, although it represented a major role in promoting the work. So it was necessary for the legal protection to be regulated in order to allow them to benefit from the entire moral and economic attributes resulted from their work. To remedy the absence of protection due to copyright applicable traditional rules, a new protection system was created: that of related rights2. On international level, this led to the adoption in 1961 of the Rome Convention for the Protection of Performers, Producers of Phonograms and Broadcasting Organizations3, considered in the literature4 as arising of the Bern Convention, alongside the TRIPS Agreement and the WIPO Treaties in this filed.

Closed and exact functions in the context of Ginzburg-Landau models
Anamaria Savu
Mathematics , 2005,
Abstract: For a general vector field we exhibit two Hilbert spaces, namely the space of so called closed functions and the space of exact functions and we calculate the codimension of the space of exact functions inside the larger space of closed functions. In particular we provide a new approach for the known cases: the Glauber field and the second-order Ginzburg-Landau field, and for the case of the fourth-order Ginzburg-Landau field.
STUDY ON THE USE OF DEM TO THE ACHIEVEMENT OF RISK AND HAZARD MAPS
Caius DIDULESCU,Adrian SAVU
Geographia Napocensis , 2011,
Abstract: This article discusses the advantages of using different types of DEM to the achievement of risk and hazard maps. Models are used to study the real physical phenomena, to create a more precise picture of reality, especially for creating a virtual prototype that describes the structure and behavior of natural phenomena in different conditions.
Trends in Banking System Globalization
Emanuela Mihaela Savu
Theoretical and Applied Economics , 2006,
Abstract: The research comprises four chapters: internationalization and banking concentration – in the last two decades, banking systems from developed economies undergoing an unprecedented process of transformation: due to the internationalization and to the concentration of the banking activities; multinational banks – globalization led to the appearance of new centers of power, exercising a seemingly growing influence; banking partnerships/alliances – have become an alternative to the organic growth strategies, engaging in diverse organizational structures, from distribution agreements on various financial services to the formation of new entities; free banking areas – have set the pace for new trends in the global financial services industry.
Earth – Mars Similarity Criteria for Martian Vehicles
George SAVU,Octavian TRIFU
INCAS Bulletin , 2010, DOI: 10.13111/2066-8201.2010.2.3.9
Abstract: In order to select the most efficient kind of a martian exploring vehicle, the similarity criteria are deduced from the equilibrium movement in the terrestrial and martian conditions. Different invariants have been obtained for the existing (entry capsules, parachutes and rovers) and potential martian exploring vehicles (lighter-than-air vehicle, airplane, helicopter and Mars Jumper). These similarity criteria, as non dimensional numbers, allow to quickly compare if such a kind of vehicles can operate in the martian environment, the movement performances, the necessary geometrical dimensions and the power consumption. Following this way of study it was concluded what vehicle is most suitable for the near soil Mars exploration. “Mars Rover” has less power consumption on Mars, but due to the rugged terrain the performances are weak. A vacuumed rigid airship is possible to fly with high performances and endurance on Mars, versus the impossibility of such a machine on the Earth. Due to very low density and the low Reynolds numbers in the Mars atmosphere, the power consumption for the martian airplane or helicopter, is substantial higher. The most efficient vehicle for the Mars exploration it seems to be a machine using the in-situ non-chemical propellants: the 95% CO2 atmosphere and the weak solar radiation. A small compressor, electrically driven by photovoltaics, compresses the gas in a storage tank, in time. If the gas is expanded through a nozzle, sufficient lift and control forces are obtained for a VTOL flight of kilometers over the martian soil, in comparison with tens of meters of the actual Mars rovers.
