ORTHOGONALITY OF STRUCTURED DERIVED ENTITIES

Structured entities, derivative entities and their order are presented. The orthogonality metric for structured and derivative entities is build. This metric is implemented. The sets of structured entities and first order derivative entities will be evaluated and analyzed.structured entities, derivative entities, metric, sets.

The Management of Manufacturing-Oriented Informatics Systems Using Efficient and Flexible Architectures

Industry and in particular the manufacturing-oriented sector has always been researched and innovated as a result of technological progress, diversification and differentiation among consumers' demands. A company that provides to its customers products matching perfectly their demands at competitive prices has a great advantage over its competitors. Manufacturing-oriented information systems are becoming more flexible and configurable and they require integration with the entire organization. This can be done using efficient software architectures that will allow the coexistence between commercial solutions and open source components while sharing computing resources organized in grid infrastructures and under the governance of powerful management tools.Manufacturing-Oriented Informatics Systems, Open Source, Software Architectures, Grid Computing, Web-Based Management Systems

Understanding Heterogeneous EO Datasets: A Framework for Semantic Representations

Earth observation (EO) has become a valuable source of comprehensive, reliable, and persistent information for a wide number of applications. However, dealing with the complexity of land cover is sometimes difficult, as the variety of EO sensors reflects in the multitude of details recorded in several types of image data. Their properties dictate the category and nature of the perceptible land structures. The data heterogeneity hampers proper understanding, preventing the definition of universal procedures for content exploitation. The main shortcomings are due to the different human and sensor perception on objects, as well as to the lack of coincidence between visual elements and similarities obtained by computation. In order to bridge these sensory and semantic gaps, the paper presents a compound framework for EO image information extraction. The proposed approach acts like a common ground between the user's understanding, who is visually shortsighted to the visible domain, and the machines numerical interpretation of a much wider information. A hierarchical data representation is considered. At first, basic elements are automatically computed. Then, users can enforce their judgement on the data processing results until semantic structures are revealed. This procedure completes a user-machine knowledge transfer. The interaction is formalized as a dialogue, where communication is determined by a set of parameters guiding the computational process at each level of representation. The purpose is to maintain the data-driven observable connected to the level of semantics and to human awareness. The proposed concept offers flexibility and interoperability to users, allowing them to generate those results that best fit their application scenario. The experiments performed on different satellite images demonstrate the ability to increase the performances in case of semantic annotation by adjusting a set of parameters to the particularities of the analyzed data

Strategii pentru cresterea calitatii serviciilor de transport aerian in contextul crizei globale

Serviciile aeriene reprezinta un segment al economiei globale extrem de sensibil la fluctuatiile economiei mondiale, fiind asociat de catre un segment important de utilizatori ca un serviciu de transport de lux. In acest context, pierderile generate de fluctuatiile frecvente ale economiei globale din ultimul deceniu a dus la disparitia unui numar semnificativ de companii aeriene, restructurarea si comasarea acestora, pentru a putea face fata cu mai mult succes fluctuatiilor pietei, ca si aparitia unor noi modele de servicii pe aceasta piata. Articolul de fata incearca sa surprinda principalele probleme care pot aparea pentru o companie aeriana cat si modalitatile de solutionare a acestora. Un alt aspect tratat se refera la o clasificare a pasagerilor unei companii si gasirea mai multor modalitati de pastrare a acestora cat si a atragerii altora.globalizare, marketingul serviciilor, segmentarea pietei, loializarea clientilor, criza economic, globalization, services marketing, market segmentation, customer loyalty, economic crisis

Systemic or local thrombolysis in high-risk pulmonary embolism

Background and Aim: High-risk pulmonary embolism (PE) represents an important health problem in emergency cardiology, being associated with a high rate of mortality. The aim of this study is to assess the efficacy and safety of pulmonary intra-arterial thrombolysis with streptokinase compared to systemic thrombolysis. Methods and Results: In our study, 28 patients with acute high risk PE were treated by intra-arterial thrombolysis with clinical success rate of 96.4%, while in the group with systemic thrombolysis (24 patients) the rate of clinical success was significantly lower (70.8%). Also, pressure gradient between right ventricle (RV) and right atrial (RA) (PRV-RA) decreased significantly in patients treated by pulmonary intra-arterial thrombolysis instead of systemic thrombolysis. Mortality during the hospitalization was 0% in the group with local thrombolysis and 29.2% in the other group, with a significant statistical difference. Major bleeding complications appeared in 14.3% of the patients with local thrombolysis and in 20.8% of the ones treated by systemic thrombolysis, without statistical significance. Moreover, the proportion of minor bleeding was comparable in the two groups of patients. There was no intracranial bleeding. Disseminated intravascular coagulation occurred in 1 patient with systemic thrombolysis. Conclusions: The rate of clinical success and the regression of RV overload were significantly higher in patients treated by pulmonary intra-arterial thrombolysis. The results regarding the efficiency of the pulmonary intra-arterial thrombolysis in high-risk PE are encouraging, the mortality in these patients being significantly lower than the one for systemic administration of the thrombolytic agent.

Social Responsibility and Environmental Issues Addressed by Businesses in Romania

This article aims to analyze the situation of Romanian companies from an environmental point of view. Environmental issues are addressed very often nowadays, and they reach and affect every domain, including the economical one. Implementing an environmental management system will not only help the companies to comply with laws and regulations, but, above all, will offer them an important competitive advantage
