  • Innovative engineering - the path to the realization of original ideas and breakthrough technologies

    Ingenuity in the new science is different from the inventive technique that invented intangible tools of knowledge - concepts, principles, laws. Modern inventor of new technology, wanting to maximize their arsenal, serious scientific knowledge, without which the inventors treated wheels, the steam engine and mousetraps .In this regard, the development of the Russian innovation system needs a dramatic increase in research universities. The article deals with examples of scientific discoveries that demonstrate that the knowledge economy promising raw material economy. And in first place in the priorities therefore goes high quality engineering education. In Russia almost no programs for innovative engineering, a course which has been developed by Israeli scientists Clement Levkova and Oleg Figovsky. While it is realized only by the Open University Skolkovo. In particular, this course shows that the development of innovative products is the preparation and implementation of innovative changes and consists of interconnected phases forming a unified whole. The innovation process involves the creation, development and dissemination of innovations. It is a common goal of a certain subject innovation economy. This activity is aimed at implementing the completed research and engineering applications in the form of new or significantly improved and marketable product. Results of innovation are new or modified processes used in practice, as well as associated with these changes, additional research and development. Innovative engineering is based on the systematic, focused and coordinated interaction of all participants in the innovation process at the executive level. However, the implementation of the innovation life cycle stages of technical innovation central figure is an innovative engineer. Innovative engineer carried out the task of building a functional model (structural and functional image) future innovation and its prototype. Without the introduction of this course is difficult to expect a breakthrough in the Russian engineering education.

    Keywords: engineering education, innovation process, innovative engineering, innovative engineer.

  • Spatial organization grouping signals in associative processes of artificial neural networks

    The article discusses issues related to the development of the optimal structure of neural networks. One of the major problems in the synthesis neural conrollers is ensuring optimal number of neurons and connections between layers  in the network. Necessary to achieve a compromise between the representational network capabilities, and memory that will be required to store it. The article presents a number of heuristics, allowing to reach such a compromise by limiting the number of connections for each neuron.
    This is done through the introduction of two characteristics for the neuron: the radius of the coverage and density of connections. Coverage radius determines the number of neurons that could potentially have a connection to this neuron, and the density of the compound gives the actual number of such compounds. Altogether, these characteristics determine the amount of synaptic connections, which can have a neuron. The article presents the heuristics that allow to define these characteristics depending on the network structure.

  • Model of dynamic management of a laser beam and a blood-groove on the basis of a biological feed-back

    The method of laser therapy is based on synchronization of phases of inflow (anacrotism) and outflow of blood (catacrotism) in the field of the pathological center with phases of a being narrowed and extending laser spot on a projection of this pathological center. It is supposed that being narrowed on a projection of the pathological center the spot of laser light stimulates blood inflow to the spot center, and the extending spot of a laser beam – activates blood outflow in the direction from the spot center to its periphery. The developed technique of the automated correction of hemodynamic frustration consists in pilot signal formation (in charge of the power and laser positioning) for the laser machine on the basis of a difference between a reference rheogram and a rheogram of the patient (a body site) in real time.The offered technique has to allow to use more efficiently methods of laser therapy at treatment of violations of a blood-groove. The technique is calculated on the basis of numerical experiment by means of methods of mathematical model operation.In the real experiment the question of synchronization of the reference and measured signal is considered solved though this task represents a subject of separate researches.The received pilot signal can be in real time transformed to the current signal operating positioning and laser power.The method gives the chance of an operating control of a condition of the patient and blood-groove diagnostics to, in time and after a session of laser therapy. Development provides possibility of adaptive individual correction and optimization of parameters of influence during a session and a course of treatment.
