Această carte prezintă o scurtă introducere în dezvoltarea aplicațiilor WEB, urmată de un studiu de caz pentru realizarea unei hărți de dispersie a poluării, prin utilizarea programării în JavaScript, a funcțiilor grafce din HTML5 și a framework-ului qooxdoo. Este prezentată conectarea la bazele de date prin utilizarea PHP și a tehnicii Remote Proc...
Conference Paper
In logistics of stocks, items/parts information are embodied in product nomenclatures. They may change due the variety of production growth in conditions which the codification of parts used can remain unchanged. Also, can occur in nomenclature, various items/parts with incomplete information. This dynamic can generate a number of issues related to...

Most software applications are based logistics stocks classic architecture witch use database tables with inputs (receipts), outputs (deliveries), stocks and other related tables. This architecture is difficult to use if the system includes multiple warehouses and the items have a route between warehouses. This type of software architecture makes i...

Quality control can be regarded as an adjustment mechanism in workflows. The quality criteria imposed by the quality manual (future references in the automatic control system) can be interpreted using concepts of systems theory and automatic control systems. The mechanism for implementing the elements of the quality manual can be built in the contr...

In the procedural programming can directly evaluate the immediate results so that the developer can assess the progress. In the case of object oriented programming, even the application can operate correctly, in case of extending or modification it can be seen a number of problems due to the objectually organizing application. It is difficult to ma...

Certified test and trial laboratories perform activities that are involved into a severe rigor. The laboratory activity is quantified starting from quality book. The resulted system is decomposed in order to apply classic methods of modeling and optimization or/and expert systems techniques. At global system level we have a hybrid technique for mod...

The proposed system may be used for the monitoring of the atmospheric pollution by the environmental agencies, organizations of environment's protection, large pollutants etc. In order to atmospheric pollution monitoring it is possible to detect and to measure the atmospheric pollution concentrations with a system composed by: I. Hardware system: S...
Article
Besides new observations, mining old photographic plates and CCD image archives represents an opportunity to recover and secure newly discovered asteroids, also to improve the orbits of Near Earth Asteroids (NEAs), Potentially Hazardous Asteroids (PHAs) and Virtual Impactors (VIs). These are the main research aims of the EURONEAR network. As stated...
Article
In the digitized information from the plates archive errors may occur caused by several factors as: physical degradation of the plates, digitization process (from scanning, photographing etc.), measurement processes (to obtain the coordinates for certain celestial objects that are on that plate), etc. By making comparisons between common areas, sim...

Teaching 'Data analysis and optimisation' deals both with theoretical aspects and simulation tools. This paper describes an approach based on using a software package useful both a teacher's tool and a stand-alone unit adequate for learning and research. The following major themes will be considered: linear and non-linear regression, linear optimis...

We present CCD, photoelectric, and video observations of selected mutual phenomena of the Galilean satellites. The campaign was carried out in Bucharest and Cluj-Napoca as part of the PHEMU2003 international effort. Five different optical systems were used for data acquisition. Here we report the observational results obtained in acceptable meteoro...

In the past several years some new mathematical techniques - such as neural networks (NNs) and fuzzy logic (FL) - have been shown to be very effective prediction and optimization tools to improve the efficiency of some operations like crushing, classifying, burning and grinding in the cement industry. The European standard EN 197-1: 2000 contains a...

The control of the pollution dynamic supposes the control of the whole pollution chain, starting from production planning and ending with pollution parameter measurements. This paper describes a software system that will scan the pollution activity specific for cement plants and will propose logistical solutions with the purpose of pollution contro...
Conference Paper
The optimal design of the fault-tolerant distributed systems, from the point of view of the reliability requirements, is considered. A Monte Carlo controlled search method is used to estimate the failure rates appearing in a constraint optimization model .
Article
The paper presents some CCD observations of Galilean satellites' mutual phenomena, made in Bucharest, during PHEMU'97 observational campaign. There are included only the light curves of the mutual phenomena that were not obtained on the base of Gaussian fitting of the measured objects; it is the case of the observed occultations.
Article
The paper presents an utility software, made by us, for measuring the differences between the computer clock and the National Radio Station clock. This is necessary for CCD images acquisition.

The goal of the NATO project EST.CLG.979542 is the optimal control of pollution for cement plants and the risk of environmental damage. The control of the pollution dynamics supposes the control of the whole pollution chain, starting with production planning and ending with pollution parameter measurements. Also guidance for local authorities and d...
