The National Institute of Research and Development in Mechatronics and Measurement Technique (INCDMTM) is subordinated to the Economy and Finances Ministry and mainly activates in the scientific research and technical development of mechatronics and measurement techniques. INCDMTM is the sole National Institute that works in the mechatronics field, a complex innovating science that comprises knowledge of fine mechanics, informatics, electronics, robotics and sensor knowledge. Founded in 1971, with technical design, development and optimization of measurement devices as the main activities, reorganized in 1996 as a national research and development institute, INCDMTM is accredited and operates based on economic management and financial autonomy. Currently, INCDMTM is developing scientific research and technical development in mechatronics and smart measurement techniques, contributes to the elaboration of the area development strategy and at the priority execution of the scientific and technological objectives established by the National Scientific Research Plan, the Research - Development sectoral Plan and by the Nucleus Programme, elaborates projects of Technological Development and Innovation and participates with projects at European Research Programmes. Within the current situation where the state funding component for research - development activities is decreasing even more, accessing European funds is a viable solution for completing and ensuring the necessary resources for running the research - development activity. Implementing projects financed through European funds relies on the management ability of the institute that accesses the funds for ensuring: - collaborations with national and international partners that promote research projects on specific areas; - a professional team for preparing the projects; - experienced project managers.

This scientific treats Research, Development and Innovation components as opportunities and chalenges for creating strategic framework for achieving romanian economic and industrial competitiveness, which represents the fundamental basis of progress and positive development of the future society. Under the new European status of Romania, it is based on the new legislation and regulations compatibility, complementarity and reciprocity with the EU and in particular with those coresponding to the Euroapean Research Area. So far, even in the next future, research in Romania, reached negative signals and that will get even the evolution of romanian society, as a result of this situation. In this regard, RDI- CCIB Section manifested towards modernization and efficiency of research and national research system in Romania.

The paper focuses on the analysis of an electro-pump with a mechatronic regulation device, extant in the laboratory of INOE 2000-IHP Bucharest that contains a MOOG servo-pump and an electric engine. The original aspects of the paper are the realization of a series of simulation models in AMESim, specific to the servo-pump and transmission. Objectives of the paper: - determining the behaviour of a volumetric hydraulic pump, with adjustable capacity, equipped with a numerical configurable module for the realization of various types of compensators (debit, pressure, power, minimal compensator); The simulations were carried out with the aid of the AMESim simulation programme. By numeric simulation of the functioning of volume pumps, equipped with an electronic command block, a pressure transducer and a displacement transducer for indirect measuring of the capacity of the pump, were highlighted the possibilities for configuring of the electronic block for obtaining various types of compensators, without requiring the modification of the structure of the pump. The simulations were executed for pumps equipped with numeric, power and minimal debit compensators. The results obtained are synthesized in a graphic form. The simulations on the functioning of the volumetric pump equipped with the minimal compensator have highlighted the fact that this type of compensator approximates very well the Load Sensing mechano-hydraulic device. This type of compensator has the advantage that it eliminates the hydraulic dross in the pent pipe of the pump, needed for measuring the debit and, consequently, the load losses are eliminated and accordingly the energy losses in the system. The results obtained after the numeric simulation of the functioning of the experimental model of the booth realized in laboratory allow us to appreciate that the of hydraulic functioning offer the possibility to carry out complex experiments, for the study of diverse phenomena that may occur in hydraulic drive systems with secondary regulation and energy recovery.

The high-tech industries are characterized by the obtaining of temporary monopoly rents caused by the barriers to market entry of these products of competitors; generating a cumulative process of the specialization. The achievements in the field of nanoscience and nanotechnology have a major impact. The benefits of these new technologies are including materials and manufacturing processes, electronics, computers, telecommunications and information technology, medicine and health, environment and energy storage technologies and biological agriculture. The subject covered by this article is the monitoring of each stage of the technological process of manufacturing microelectronic circuits, in particular by SEM and AFM microscopy because the problems that arise in these flows nanotechnology depends on the quality and the processing of surfaces. © 2014, Editura Cefin.

The paper concerned with the theoretical and experimental research on using nonconventional energy sources for hybrid vehicles. The combustion cells could be future alternative solutions taking into account their high levels of efficiency compared with those of the well-known energy types. Considering that the combustion cell transforms directly the combustible in electrical current, it could be used for the electric-hybrid vehicles. In order to carry out the experimental research, it has been used a vehicle model with a photovoltaic cell, a reversible protonic membrane cell (PEM) and two tanks, one for the hydrogen and the other one for oxygen. © 2014, Editura Cefin.

The paper presents a constructive solution regarding laser micro-welding of a new mechatronic component belonging to the aluminum alloy sensors category. The laser welding process of aluminum alloys is particularly complex because the aluminum alloy has a very high reflectivity and in most situations it requires a specific surface pretreatment. Due to the physical characteristics of the material and the precise positioning requirements of the parts that are to be assembled through laser micro welding, the system designed and realized has specific operating conditions. After laser micro welding, the sensor was tested and all initial conditions imposed were satisfied: the sensor was pressure tested with very good results and we didn't have difficulties to integrate the sensor in the mechatronic structure for which was designed. © 2014, Editura Cefin.

The paper deals with the Fused Deposition Modeling (FDM) technology applied for manufacturing the mechatronic sun gear differential assembly. The Rapid Prototyping technology is a great opportunity for manufacturing the parts based directly on the designed three-dimensional model by using the 3D printer. Following the research goals, there are presented the main criteria for setting the parameters required by the 3D printer. There are included the stages of software processing too. Finally, an optimum printing process for the mechatronic assembly was achieved. © 2014, Editura Cefin. All right reserved.

Micro-nanometrologically and topographic characterization of materials is important to determine features of different surfaces that are used in many areas. During the time, depending on the application, the surfaces deteriorate having a complex deterioration mechanism. The changes that appear on these surfaces and wear particles can be characterized using different equipment and techniques. A mechatronic system made up of an atomic force microscope and a robotic nanomanipulator is used at INCDMTM, in order to characterize steel, titanium alloys, CoCr alloys or polycrystalline surfaces. It is a proper system to study surfaces of different materials from the tribological point of view. © 2014 The Authors. Published by Elsevier Ltd.
