Development of information and communication technologies has influenced the evolution of all kinds of computer applications in the organization. At the same time external environment and phenomenon of globalisation have become more complex with new requires and conditions for enterprises. In that context, effective information system has become necessity for every organization in order to …
Wireless automation is an emerging field of research, engineering and industrial development that aims at significant savings in installation times and costs of cabling in automation systems, while providing a new level of flexibility for system design, reconfiguration, and agility. It is applicable to both new automation systems and retrofit applications. The use of wireless…
The aim of this paper is to describe a new optimization method that can create control equations of general regulators. For this type of optimization a new method was created and we call it Two-Level Transplant Evolution (TLTE). This method allowed us to apply advanced methods of optimization, for example direct tree reducing of tree…
The market for many industrial production companies is getting tougher as the global competition is increasing. The collaborative manufacturing model, see Figure 1 (Gorbach & Nick, 2002), reflects the fact that companies today need to collaborate both externally and internally to reach success on the market. The external collaboration is presented through the two horisontal …
Real control of industrial processes is almost always burden with various perturbations, disturbances and changes in process parameters or dynamics due to varying operational conditions, plant properties themselves, etc. Furthermore, an acceptable a priori mathematical model does not have to be known. In spite of it, such processes have to be controlled. A possible solution …
The state of present technologies in technical and also non-technical practice is represented by growing complexity of systems. A turbojet engine as a complex system is multidimensional highly parametric system with complex dynamics and strong non-linear behavior with stochastic properties. Its particular property is operation in a wide spectrum of changes of its operating environment …
1. Specific heat of Nanocrystalline materials (Cu, Ru, Pd) are higher than their bulk counterparts. 2. The melting point of nanoparticles decreases dramatically as the particle size gets reduced 3. Thermal conductivity of Nanotubes are more than twice the conductivity of diamonds. 4. Thermal management: Carbon nano tubes (CNTs) have good thermal conductivity properties and…

· Magnetic moment: In nano-materials as large number of atoms are present in the surface, they have low co-ordination number and hence possess local magnetic moment with in themselves. · Due to large magnetic moment these nano-materials emhibits spontaneous magnetization at smaller sizes. · Super-paramagnetism is a form of magnetism, which appears in small ferromagnetic (or) ferrimagnetic nanoparticles….
· Change in colour: In semiconductors, bandgap changes with particle size; bandgap is the energy needed to promote an electron from the valence band to the conduction band. As particle size decreases, bandgaps increases and so wavelength of light emitted by the particles decreases. When the bandgaps lie in the visible spectrum, a change in bandgap…
