Dambovita - 50 km between good quality and ecological disaster
DUMITRU MORCOTET,NINA JIPA,LIUDMILA MARIA MEHEDINTEANU
Cinq Continents , 2011,
Abstract: Dambovita - 50 km tra buona qualità e disastro ecologico. Dambovita è il principale corso d'acqua che attraversa Bucarest. Quindi, è l'acqua collettore delle acque reflue, industriali e pluviale generati all'interno della città, arrivando prima attraverso la rete fognaria al impianto di depurazione Glina. Quest’ultimo, però, non è ancora funzionale, dumping le aque reflue nel fiume senza trattamento preliminare, che portano ad una forte degradazione dellaqualità dell'acqua, che è in clasa scarsa qualità incorniciata iniziando dall punto della perdita Glina fino a che la fuoriuscita in Arges. Fare determinazioni delle principali proprietà fisiche e chimiche delle acque in punti scelti in modo da fornire una panoramica di come la loro qualità è subito a causa delle fonti diinquinamento nella zona di Bucarest, un generale degrado del fiumeDambovita da monte a torrente fu trovato, le cui acque contaminate influiscono la qualità condizione dell collezionista Arges, così come la freatica che si trova ad una distanza di diverse centinaia di metri da esso.

Assessment of Seagoing Ships Longitudinal Strength in the Context of International Rules, Important Factor for Safe Operation  [PDF]
Dumitru Lupascu, Ionel Chirica
World Journal of Engineering and Technology (WJET) , 2015, DOI: 10.4236/wjet.2015.34029
Abstract: The paper is focused on the ship hull safety problems related to the longitudinal strength of the ship during design, construction and service in context of International Goal-Based Ship Construction Standards carried out by International Maritime Organization (IMO). The study underscores the importance of ship longitudinal strength for prevention of theirs losses, mentioning the most important measures taken by IMO for improvement of ship safety. In the work, a critical analysis of the methodology of the International Association of Classification Societies (IACS) for calculation of sectional efforts induced by waves in ship’s hull is described. Finally, a calculation base proposal for improvement the efforts on quasi-static layout of the ship on wave is performed.

-absolutely summing operators on the space and applications
Dumitru Popa
Abstract and Applied Analysis , 2001, DOI: 10.1155/s1085337501000434
Abstract: We give necessary and sufficient conditions for an operator onthe space C (T,X) to be (r,p)-absolutely summing. Also we prove that the injective tensor product of an integral operator and an (r,p)-absolutely summing operator is an(r,p)-absolutely summing operator.
Interpretation of ECG Signal with a Multi-Layer Neural Network
Dumitru Ostafe
Journal of Applied Computer Science & Mathematics , 2008,
Abstract: In this article there are introduced the resultsobtained in the interpretation of the components of abiomedical signal, ECG, by using a multi-layer neuralnetwork, using the backpropagation algorithm. The neuralnetwork was simulated with the Neuroshell2.0 program. Thenew obtained network was used within the program ofautomate diagnosing of the ECG.
THE DYNAMICS OF THE MATRICS STRUCTURE
Dumitru CONSTANTINESCU
Management & Marketing , 2007,
Abstract: The relationships organization-suppliers-customers have recently known major changes in the structure of services and have made the organization develop its managerial and professional competencies in order to do projects. The qualified organization is the most trust-worthy in the process of doing a project. The participation of an organization in doing projects depends on a multitude of factors. Out of these factors, the structural organization comes forth, as it represents the variable with the most important impact on a project’s quality, costs and lead time. From the organizational point of view, the matrix structure is frequently chosen for projects. The matrix structure generally coexists with the line structure. The two structures are contrastive. The line structure is based on the unity of command principle and is not open to cooperation and dialogue. The matrix structure encourages cooperation and communication, favours conflict, which is considered here a healthy and essential process. The matrix structure and the line structure claim their right to initiative. Conflict and the multidimensional integration of multiple hierarchies can be negotiated through the concept charisma – mediation, sustained by the matrix structure.

Measures with relatively norm compact range and infinite-nuclear operators
Dumitru Popa
Le Matematiche , 1995,
Abstract: We prove that measures with relatively norm compact range correspond to the infinite-nuclear operators and to a p-Bochner integrable function (resp. p-Pettis integrable function) correspond a p-nuclear operator (resp. a q-nuclear operator).
