Ilie: the role of the double reverssible skin-pass in
compensating the negative effect of high temperature of the hot rolled strip,
destined to enameling. Industrial experiments Metalurgia
(59) 2007, nr. 11, p. 5 In the cold-rolled strip production process, out of
the hot-rolled strips, there is well-known the negative effect that the
high-temperature of the latter has on the quality of the process. Own
experiements are presented, consisting of the the double reverssible
skin-pass process which helps in the compensation of the effect mentioned.
The present study includes industrial investigations. D.C.:

Maricel, MIREA Constantin, MAZILU Nicolae: About thermodynamics of the deformation by analogy with the
thermodynamics of the non-equilibrium processes. Part III: The energy
transfer to the thermostat and the random walk correspondence with
the Bohm potential Metalurgia
(59) 2007, nr. 11, p. 9 On define a solid body and beginning from this point
on research the thermal transfer to the thermostat. Because such transfer
implies random walking, on research this problem and on determine the
correspondence with Bohm potential. D.C.:

composites. Production and casting of composite mixture Metalurgia
(59) 2007, nr. 11, p. 15 The paper presents the principal
aspects regarding the obtainment of the mixture aluminium - silicon carbide
particles. There are analysed: the method of components mixing, the forces
which act on the particles during their inclusion into the liquid matrix, as
well as the silicon carbide particle displacement through the metallic bath.. The paper deals with the analysis of
the silicon carbide particles inclusion in the liquid matrix by mechanical
agitation. Aso, the mechanical stirring conditions necessary to realize the
mixture are analysed. Some impeller parameters and values of the ratio
between the diameter of the stirring and the diameter of the ladle are
presented. The article contains information
about the forces which act on the particles and determine their movement
inside the liquid matrix. The agglomeration tendency of particles during the
settling process is also presented. The settling process of the silicon carbide particles
in the melt as a function of particles size, shape and volumetric
concentration as well as the agglomeration tendency of the particles are also
analysed. Finally, typical defects of composites processed by mechanical
mixing and gravitational casting are shown. D.C.:
669.05 Vizureanu Petrică, ŞTEFAN Mihai: Metodology for working out of simulation of
high complexity metallurgical processes simulation Metalurgia
(59) 2007, nr. 11, p. 21 An experience is firstly
performed in order to validate the simulation model, base don experimental
data. The purpose of this experiment is to see whether the behaviour of the
mathematical model is not in contradiction with the behaviour of the
simulation model, according to the noncontradiction criterion. Simulation
results are obtained and compared to the real results for model validation. D.C.:

drawing Metalurgia
(59) 2007, nr. 11, p. 27 Dieless
drawing is an incremental
process of plastic
deformation which presents some
important advantages in comparacy
to the conventional drawing |
processes. Dieless drawing make posible the
deformation of a wide range of materials by controlling the local
heating/cooling temperature without using dies. The aim of this paper is to
present the influence of the main parameters of the process(drawing
speed, temperature, reduction, inductor type) on the drawing efort. Key words: target costs,
direct costs, indirect costs, price, benefit, cost Lepădatu V.
Gheorghe: The target costing Metalurgia (59) 2007, nr. 11, p. 32 The method of target costing represents a strategic managerial approach for
products, in which of cost carriers are analysed during the entire life cycle
and particularly during the conception stage. Key words: strategy, company, targets, competitive advantage, strategic options Carmen Judith Grigorescu: Strategic components
of industrial enterprises Metalurgia
(59) 2007, nr. 11, p. 36 In this paper,
starting with different definitions of management strategies, I analyzed
their main components in an industrial enterprise environment. Key words: adaptation through deregulation, innovation,
des-intermediation, diversification/specialization, markets deregulation /
de-structuring, virtual counter, mobile financial/banking services, markets
equilibrium / disequilibria Ileana Nicula: Banking
adaptation and
innovation answer to globalization (I) Metalurgia (59) 2007, nr. 11, p. 41 The papers are focused on
adaptation and innovation in the banking financial sector as an answer to the
globalisation phenomenon. The banking-financial
activity is acting as a specific manner by adapting and innovating processes
to the manifested trends. The concrete way to respond
to these challenges could be considered contradictory:
diversification/specialisation, reglementation/dereglementation, resulting a
continuous remodeling process. In this respect, the instability receives a
positive role, because the current trend is the unbalance, the balance being
a provisional phenomenon among unbalances. Which the answer of the banking-financial
sector to this challenge? Currently, the
competitional environment is not different of what it was 20 years ago.
Nevertheless, which are the specific features? Key words: software
engineering, software quality, software evaluations, software quality
attributes, quality indicators Mihaela
Mureşan: Software
Engineering End-Users and Software Quality Standards Metalurgia
(59) 2007, nr. 11, p. 45 The end-users are directly involved in the
development of the software products, during the design of the product,
through specific requirements definition, and during the evaluation process
of the software. The metallurgical enterprises, where the quality of the
software products is crucial for the efficiency of the internal processes,
are very interested in the design and implementation of the specific
software. Quality should be looked at as a strategic initiative in software
engineering. By taking a pro-active and iterative approach to software
evaluation during the development processes, it is possible to build
high-quality applications faster and more efficiently and with direct
benefits for the users. The software quality has
a crucial importance for the evaluation of the software especially in the
digital economy. Consequently, a specific standard was developed as a quality
model. The evaluation tools offered by the quality model framework could be
implemented for the assessment of the internal quality, as well as for the
evaluation of the quality in use. The integration of all actors view in the
software quality model represent other important achievement which
contributes to a more secure and reliable use of the information systems. The
decomposition of the quality attributes identified in the software quality
standard in specific indicators which can be measured represents a practical
side of the model facilitating its implementation. |
