The Rank-Size Relationship in the Urban Settlement Network in the Turda - Alba Iulia Corridor
Journal of Settlements and Spatial Planning , 2011,
Abstract: When studying the rank-size relationship in the settlement system, principles like hierarchy, centrality, and specialization should be the prevailing instruments, whilst primacy should be considered just to a lower extent. According to the NPSP (National Plan of Spatial Planning) in the Turda - Alba Iulia Corridor there are settlements of rank II, III and IV, correspondingly municipalities as county capitals, other municipalities and towns. According to the NPSP, rank II may correspond to differently ranked localities, such as Alba-Iulia and Aiud. However, the first mentioned clearly has a larger size from the perspective of administration, service, and equipment facilities (hospitals, supermarkets). The relationships between the urban centers in the Turda - Alba Iulia Corridor can be grouped into four categories: county subordinate relationships, relationships of inter-county independence, relationships of local competition, and local collaboration relationships. The subordination relationships prevail in Alba County, as they are induced by the hierarchic position of its capital town, Alba Iulia, which is a classical case of administrative subordination. The independence relationships are developed between the urban settlements in Cluj County and those in Alba County. Relationships of competition appear mainly between the urban centers in the same county, both in Alba and Cluj. Relationships of collaboration are developed between Turda and Campia Turzii towns, although relations of competition were also identified between these two.

Abstract: The unemployment is a social phenomenon all over the world. In Romania, after 1990, two major Laws structure the approach to unemployment: Law nr.1/1991 and Law nr.76/2002. Current article analyses from a juridical point of view several issues concerning the implementation of the legislative framework.

Abstract: The article dwells on the juridical aspects of disciplinary responsibility in Romanian Labor Law, regulated by the Labor Code enacted in 2003, and especially on the disciplinary regulations adopted by the employers.

Abstract: This paper presents the main characteristics of the youth labour market, with a special view on mobility, career development and incomes. The paper is substantiated by and continues the researches of the authors on the topic of labour force mobility and on the one of adaptability, respectively on youths' beahviour on labour market (with particular consideration of young graduates) highlighting the factors that adjust choices regarding taking up a job, career advancement, labour motivation, professional and personal satisfaction opportunities which are provided by the labour market at local level, in country and abroad. Quantitative and qualitative indicators are presented about Romanian youths' labour market within the European context during the transition period. The impact of the crisis on youths' labour market is analysed, highlighting the challenges and opportunities, the particularities of the newly created jobs and especially the knowledge, skills and competencies requirements (KSC). The authors propose both the improvement of the systems of indicators for defining the potential and presence of youth on the labour market, the economic and social impact of external mobility of young graduates and an integrated scheme of policy measures for promoting adaptability and performance integration on Romanian labour market of youth. Particular attention is paid to presenting policy instruments for halting/diminishing the brain drain and brain shopping phenomena by promoting an attractive (professionally and monetary) supply for employment in Romania's local economy. The authors succeed in highlighting the functional links between the education market (labour force supply) and labour market (employment demand of the business environment) underpinning the requirement of integrated management of labour potential in the years preceding studies' finalization and up to the post-insertion years by multi-criteria analysis models and graduate career tracking programmes. Correlative measures are suggested for policies, procedures and monitoring instruments of youths' adaptability on labour market, as alternative to external migration/mobility for labour.
Youths on labour market.Features. Particularities. Pro-mobility factors for graduates. Elements of a balanced policy for labour migration

Revista Romana de Economie , 2011,
Abstract: The youths’ labour market, and especially insertion employment has a series of particularities defined by aspects such as: flexibility, efficient employment, interest for career but also informal employment, external mobility, including brain drain, segmentation, employment precariousness, income disadvantages, etc. Therefore, also the labour market policy and particularly managing labour mobility especially through the economic and social effects that might be triggered on the local labour market in the origin country, presents a special importance under the conditions of the economic turnaround stage, by promoting new and sustainable jobs, based on knowledge and competences. In the present paper an analysis is made about the youths’ labour market features, and the outcomes of an empirical analysis about graduates’ migration propensity are presented. Suggestions are made for developing a balanced policy for youths’ labour mobility to the benefit of the country of origin.
A Mathematical Model for Logarithmic Image Processing
Vasile Patrascu,Vasile Buzuloiu
Computer Science , 2014,
Abstract: In this paper, we propose a new mathematical model for image processing. It is a logarithmical one. We consider the bounded interval (-1, 1) as the set of gray levels. Firstly, we define two operations: addition <+> and real scalar multiplication . With these operations, the set of gray levels becomes a real vector space. Then, defining the scalar product (.|.) and the norm || . ||, we obtain an Euclidean space of the gray levels. Secondly, we extend these operations and functions for color images. We finally show the effect of various simple operations on an image.
Image Dynamic Range Enhancement in the Context of Logarithmic Models

Computer Science , 2014,
Abstract: Images of a scene observed under a variable illumination or with a variable optical aperture are not identical. Does a privileged representant exist? In which mathematical context? How to obtain it? The authors answer to such questions in the context of logarithmic models for images. After a short presentation of the model, the paper presents two image transforms: one performs an optimal enhancement of the dynamic range, and the other does the same for the mean dynamic range. Experimental results are shown.
Color Image Enhancement In the Framework of Logarithmic Models
Vasile Patrascu,Vasile Buzuloiu
Computer Science , 2014,
Abstract: In this paper, we propose a mathematical model for color image processing. It is a logarithmical one. We consider the cube (-1,1)x(-1,1)x(-1,1) as the set of values for the color space. We define two operations: addition <+> and real scalar multiplication . With these operations the space of colors becomes a real vector space. Then, defining the scalar product (.|.) and the norm || . ||, we obtain a (logarithmic) Euclidean space. We show how we can use this model for color image enhancement and we present some experimental results.
The Affine Transforms for Image Enhancement in the Context of Logarithmic Models

Computer Science , 2014,
Abstract: The logarithmic model offers new tools for image processing. An efficient method for image enhancement is to use an affine transformation with the logarithmic operations: addition and scalar multiplication. We define some criteria for automatically determining the parameters of the processing and this is done via mean and variance computed by logarithmic operations.
