Romanian specifics within the framework of regional economic cooperation
No full textThe various forms of economic cooperation are so many channels for the Romanian economy to connect itself to European and International Economy. That is why, by making use of R&D (Research & Development) cooperation mechanisms, Romania could access - even in times of transition but with the help of its national highly qualified labor force - peak technology sectors. By developing production capacities in cooperation with companies from the European Union, Romania’s affordable (cheap) labor, natural resources, commercial facilities could be driven to the technology of the third millennium. Cooperation with regard to marketing and sales is leading to the integration of the Romanian market into the European one, increasing the awareness of market requests and improving negotiation skills. High technology, new technique, trade under the auspices of international competition are steering the capitalization and management of natural, human, financial and information resources, facilitating both the integration processes and the economic and social development.cooperation, technical, production, trade, development
Rencontre Nicolae Grigorescu – William Ritter. Perspectives des historiens de l’art
No full textThe art historians G. Oprescu (1881–1969) and Remus Niculescu (1927–2005) are those who studied closely the life and work of Nicolae Grigorescu (1838–1907), the most famous Romanian painter in the XIXth c., who left the Ecole des beaux-arts in Paris for the free school of Barbizon. This paper examines their positioning toward Nicolae Grigorescu’s relationship with the Swiss art critic William Ritter and raises question of subjectivity of interpretation. G. Oprescu’s view, who was also the publisher of William Ritter’s letters to the Romanian painter, is an excessively and incomprehensibly negative one. I will use also some inedited manuscript marginal notes of G. Oprescu on Ritter’s letters. Remus Niculescu avoids any comment on G. Oprescu’s opinions and examines rigorously from an art-historical perspective the texts written by William Ritter on Nicolae Grigorescu’s painting, published in different foreign art journals. Between focusing obsessively on the personal relationship of the two friends and ignoring them totally I will try to argue another view on the meeting Grigorescu-Ritter
Romanian public marketing in terms of necessity, collaboration and mix
No full textThe paper carries out a short literature review on public sector and public marketing terms. The findings of the paper’s study shows that the Romanian public sector should give more importance to marketing activities, as 87% of the respondents sustained when asked about their necessity. Within a public institution, the marketing specialists should cooperate with research& development, sales and financial departments. The study results reaffirm the importance of the 4 P of the marketing mix when making an offer, and place them on the top positions.public marketing, knowledge, specialists, cooperation
Authentication of a Painting by Nicolae Grigorescu Using Modern Multi-Analytical Methods
No full textThe paper presents the expertise of authenticating a painting by Nicolae Grigorescu through the involvement of multi-analytical techniques, in order to identify and evaluate some archaeometric and chemometric characteristics of the pictorial materials and of the support, used in determining the age. The painting is made with oil colors on pressed cardboard, with preparation based on chalk powder and animal glue. The painting presents two elements as being counterfeit, which have attracted suspicions, namely the signature of the author (presenting a semi-transparent covering veil), and, on the back, a writing of dating, performed by a very controversial art historian. The investigation was carried out by direct analysis with magnification devices, in reflected UV (ultraviolet), VIS (visible), and NIR (near- infrared) light, and by OM, SEM-EDX, and μ-FTIR. The results showed that the painting is authentic and belongs to Nicolae Grigorescu, and the dating established previously by Amelia Pavel through the writing on the back is certain
Models of public – private partnership projects in tourism industry
No full textThere is a general agreement at the conception (theoretical) level about the imperative of a public-private partnership and there are various efforts do it. It is also taken into account the experience of other countries of the European Union or other developed countries able to support and to assist with their previous experience. Public – private partnership aims to high light the role of the two components in general development of society, regional, economic and company development and increase of competitiveness. All of them are subordinated to serve the objective of satisfying the population economic and social requests and/or needs. Efficient communication establishment between the two environments will conduct, for sure, to the development of a segment of satisfied citizens, employees, owner and vice-versa. The public – private partnership in tourism industry could be developed in various ways. It could start with public – private strategies, joint proposals of regulations, up to growing business together and so on. The present paper aims to underline the main issues of public – private partnership and to propose few models applicable in tourism industry. The proposed models offer an image about better usage of both environment expertise and facilities (power) some of them still open opportunities for Romania.public, private, partnership, models
System composite of the triplet’s of strategic overview – revised fundamentals
No full textThe STIQE 2004 paper presents the identified triplets at macro and micro level of the socio-economic system. Through the important triplets identified are the following: European Union (UE) – State Members (SM) – European Citizens (ECz); European parliament will (PW) – national commitment (NC) – personal desire (PD); sustainable development(SD) - environment protection(EP) - quality of life(QL); economics(EC) – social climate(SC) – politics(P); material resources(MR) – financial resources(FR) – human resources(HR); life security (peace)(LS) – food security (survival)(FS) – environment security(ES); agriculture development (AD) - industrial development (ID) – infrastructure development (IsD); jobs/salaries (JS) – affordability/ expenses (AE) - quality of life (QL). It was also proposed a way of the triplets identification, a system to organize and link them on two dimensions: micro and macro level, and to get possible final structures by linking the two plans. The output, through a geometrical approach, has to be a system of interconnected triplets able to provide potential effects on the whole by action (modification) one point, than could be use for national strategies design and effects estimation. According with the opinions expressed at the conference we decide to revise the fundamentals of the theory. So, there were settled some criteria of knots identification, triplets assemble and plans definition. The main delimitation are euro/national areas, micro/macro levels and socio/economic approaches. The revised fundamentals are based on a more structured view, able to conduct us to a better triplets assembly as a whole. Also, the selection of the knots is made more carefully taken into account the future step of their evolution and dependences expressed by mathematic functions. At the same time there were identified potential factors of knots influence. It is a step back on the theory development, but it allows a better analysis and structuring of the elements taken into account, that could be a crucial decision in reaching the right composite of the system.sustainable development, triplets, overview, strategy, fundamentals
Industry structure analysis. A case of Romania
No full textThe last years reflect, in term of macroeconomic development, the continuing advances in market-oriented reforms in the most countries of Central and Eastern Europe. Transition in this economic area includes the restructuring of politic, economic and social systems in accordance with the European Integration Directives and local industry policy, with the movements of the economic environment. Our proposed model tries to define the structure of the basic industry components, the stability degree and the intensity of the measures to be use for restructuring the industrial offer and Romanian regional structure (existing and estimated). This model is design as a link between the Pareto’s model and the Markov’s Chains transitions. The target of industrial policy is to obtain an economic environment that characterizes a stable market economy.industry, sector analysis, regional analysis, structure, Markov chains
Efficient and Error-Correcting Data Structures for Membership and Polynomial Evaluation
No full textWe construct efficient data structures that are resilient against
a constant fraction of adversarial noise. Our model requires that
the decoder answers \emph{most} queries correctly with high probability and for the remaining queries, the decoder with high probability either answers correctly or declares ``don't know.'' Furthermore, if there is no noise on the data structure, it answers \emph{all} queries correctly with high probability. Our model is the common generalization of an error-correcting data structure model proposed recently by de~Wolf, and the notion of ``relaxed locally decodable codes'' developed in the PCP literature.
We measure the efficiency of a data structure in terms of its \emph{length} (the number of bits in its representation), and query-answering time, measured by the number of \emph{bit-probes} to the (possibly corrupted) representation. We obtain results for the following two data structure problems:
\begin{itemize}
\item (Membership) Store a subset of size at most from a universe of size such that membership queries can be answered efficiently, i.e., decide if a given element from the universe is in . \\
We construct an error-correcting data structure for this problem with length nearly linear in that answers membership queries with bit-probes. This nearly matches the asymptotically optimal parameters for the noiseless case: length and one bit-probe, due to Buhrman, Miltersen, Radhakrishnan, and Venkatesh.
\item (Univariate polynomial evaluation) Store a univariate polynomial of degree over the integers modulo such that evaluation queries can be answered efficiently, i.e., we can evaluate the output of on a given integer modulo . \\
We construct an error-correcting data structure for this problem
with length nearly linear in that answers evaluation queries
with \polylog s\cdot\log^{1+o(1)}n bit-probes. This nearly matches
the parameters of the best-known noiseless construction, due to Kedlaya and Umans.

Friction and Wear Behavior of Several Hard Materials
No full textSliding friction, abrasion and erosion tests were performed on several materials: cemented carbides, partially stabilized zirconia (Mg–PSZ), electroless Ni–P coatings and SAE 4140 steel as reference material. Sliding friction test was carried out in a pin-on-disk system. A micro-abrasion test was performed using the ball cratering methods. The erosion test consisted an air stream carrying abrasive particles of SiC, impinging flat samples. Sizes of wear scars were determined by optical microscopy and laser profilometry. Scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) were employed to observe morphological and chemical features of worn surfaces. The sliding pin-on-disk results of Ni–P coating showed smooth variation of the friction coefficient (mean values of 0.16–0.21), as well as the lowest wear rate compare with the other evaluate materials. Experimental results of the micro-abrasion test showed linear behavior between wear volume and sliding distance for all the evaluate materials. Cemented carbides showed the lowest wear rates followed by SAE 4140 steel, Mg–PSZ and Ni–P coating, respectively. Erosion test values ranked evaluated materials from lower to higher eroded volume as follows: SAE 4140 Steel, Ni–P coating, cemented carbides and Mg–PSZ ceramic
