The article presents a method of accounting land limits (charges) during the cadastral valuation of agricultural land. This allows us to differentiate the cadastral value , depending of presence of protection zone,  water protection zone and on other zones on the  lands. Cadastral cost of agricultural land on the example of Leningrad region counted. Determination of cadastral cost on the basic presented coefficients will reduce the land tax on the territory which include restricted mode zones of use. It will increase the objectivity of cadastral evaluation.

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.

Use nonconventional and renewables has important economic value for energy saving. Lamellar recuperators are applied to a reuse of heat of departing air in system of ventilation of buildings. Its functional mathematical model is developed for increase of energy efficiency and optimization of parameters of work of a lamellar recuperator. On the basis of mathematical model the criterion of optimization is defined and optimum modes of functioning of a recuperator of ventilating air are established. As a result of researches it is established that the heating of external air is necessary for increase of overall performance of a recuperator before an entrance to a recuperator. For the solution of this task it is offered to use soil the heat exchanger.

The main methods of Platycladus orientalis seed propagation are studied. For Platycladus orientalis industrial cultivation the following technologies of reproduction are recommended: For off-sort samples – seed propagation after stratification (25-30 days); For sorts and decorative forms:
1.Vegetative propagation using IAA.
2. Micropropagation of Platycladus orientalis in vitro by means of adventitious shoots induction on the MS medium adding 0,2 – 0,5 mg/l BAP. There are derived well rooted microshoots on the medium with IAA in concentration 5 mg/l.

Keywords: green building, Platycladus orientalis, technologies of reproduction, clonal micropropagation.

According to the signal theory vocal speech presents a non-stationary random process due to time variation of its main characteristics. A special emotional impact is gained during ensemble and choir performances. The article provides the correlation analysis results and the autocorrelation function of ensemble singing calculated, taking into account the non-stationary nature of acoustic signals. The studies have shown that there is a certain visual resemblance between correlation portraits of a non-professional student ensemble and a non-professional solo singer. At the same time the correlation portrait of student and professional co-performance tends to a professional singer correlation portrait. This helps to make a quantitative assessment of an ensemble’s professionalism which, alongside with a vocal teacher’s subjective assessment, can provide an objective view on singers’ voices condition to optimize the academic voice training process in an ensemble, which is important when using this voice assessing method in music schools, colleges and universities.

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.
