**On the problem of surface wave damping in the conducting medium
being inhomogeneous by the frequency of electron collisions**

**Chogovadze**** M.E.**

**Georgian**** Technical University**

The impact of inhomogeneity of the conducting medium
(plasma) on surface wave damping was studied for the case when, at constant
concentration of particles (electrons), the inhomogeneity of the medium is
caused by the inhomogeneity of the frequency of electron collisions. A
correction to the decrement of surface wave damping caused by this type of
inhomogeneity was determined. It is demonstrated that, if the absorption in
homogeneous plasma is the same both in the area of normal skin effect and in
the area of inertial skin effect, the additional absorption emerging at
inhomogeneous frequency of electron collisions has different values in those
areas.

The composition, the character of chemical bonding
with the metal atoms and the thickness of the adsorbed layers on the surface of
nanoparticles were studied. The analyses of separate layers were carried out by
sputtering of the investigated surface of the sample using the accelerated
argon ions with energy of 1keV. It was revealed that, after long-term
keeping in the air, the adsorbed
layer mainly consists of oxygen in the state of the physical adsorption on the
surface of the particles of the nanosized powders of nickel and cobalt, and that it does not take part in the
oxidation of the metal atoms. Oxygen is in chemical bonding with the titanium
atoms on the surface layers of nanoparticles, though the carbon atoms are not
in the state of physical adsorption. In the following sublayers, the tendency
of carbide formation is initially observed, but at the depth of 300Å from the physical

**Abstract.
**It has been
established that, at the analysis of multicircuit systems, Maxwell’s
mathematical form of expression of electromagnetic inertia of mutual induction
results in the equilibrium equations making no physical sense and may lead to
emergency situations. Induced current is the negation of inducing current
alteration. Mutual induction between the inducing and the induced currents is
negative. The mutual induction emf resulted from a change in the induced
current in the circuit of inducing current is the negation of negation.
Negation and the negation of negation serve as physical bases of field
propagation and energy transfer. In the case of positive magnetic coupling, the
mutual induction emf is negative and it inhibits the alteration of electric
current force in the circuit, and vice versa, in the cases of negative magnetic
coupling, the mutual induction emf is positive, and it contributes to the
alteration of electric current force in the circuit. The magnetic field energy
of inductively coupled circuits is defined as an algebraic sum of energy of separate circuits with an allowance for the
sign of mutual induction. Practical tasks of mathematical modeling have been
solved.** **

**SUMMARY**

**Determination of the reliability function of nonredundant element of
power object**

**Namgaladze
D.P. and Kiziria T.I.**

**Georgian**** Technical University**

At considering the reliability indices of the system
element with recovery, the time of operation and recovery is usually accounted
for. But, in practice, there often occur the situations when, after the failure
of the system (or its element), it takes considerable time to begin repairing (time for revealing the
damages, time for organization of repairing work, delivery of spare parts
etc.).

The total dead time is called the waiting time. In the present work, the reliability
indices of the element of power object with account for the waiting time are
determined analytically by using Markovian processes.

**Keywords**: power object, reliability,
redundancy.

**Georgian**** Technical University**

When considering the indices of maintenance of
designed or operating power objects, much attention is given to the
availability factor, which is defined as the probability that the power object
operates satisfactorily at any moment of operation, and that it is a
determinate value. In the work, a stochastic quantity, the availability index,
is introduced. Its density of probability distribution is analyzed for the case
when the operating time is distributed by the exponential law, and the recovery
time obeys the Erlang law.

In practice, it is often necessary to determine the
functions representing the expected residual operating time for the power
object element which has operated without failure for some time. The density of
probability distribution of operating time could be determined from the initial
probability distribution of operating time. In this work, analytical relations
are derived for determination of the function of residual operating time in the
period of the first preventive inspection when the mean-time-between-failures
of the unrestorable element of the power object has exponential and normal
distribution.

**ON ONE HYPOTHETIC MODEL OF
ACCELERATED EXPANSION OF THE UNIVERSE**

**Sepiashvili D.P.**

**Georgian**** Engineering Academy**

The information which reaches us from the outer
environment is descrete. We can watch the real world only in particular time
intervals. Quanta permanently disappear and emerge again in the real world. The
time (Dt) it takes the quantum to
disappear from watcher’s field of vision determined by Heisenberg law: Dt ×DE ~. The lower is the frequency, i.e. the quantum energy, the
longer is the time (Dt) it takes the particle to
disappear from or to emerge in the real space. As the Universe expands, the
frequency, i.e. the energy of quanta, decreases. As this takes place, if the
number of quanta existing in the real space-time decreases, the mass of the
matter actually existing in the Universe will decrease, which, in its turn,
will make weaker the gravitational field. As the frequency of fluctuations
decreasesб the length of quanta, v=C/l, increases, i.e they
“stretch”. Probably just this phenomenon manifests itself in the
form of accelerated expansion of the Universe.

The process of tea mass

given the experimental results at harmonic mode of vibration of the working
body with variable parameters: air temperature T=320-330k; amplitude of vibrations A=0-7mm;
relative humidity of tea mass W=60-75%. It was established that, when the air
temperature at the installation inlet increased from 320k to 330k, the
time of withering decreased by a factor of 4 to 12. The vibrations with the
amplitude of 3mm hardly affected the withering rate. When the amplitude was
increased from 3mm to 7mm, the rate of withering changed significantly. The empirical formula for calculation of
the rate of tea mass withering in the VAPC layer was derived, and the optimum

The belt conveyer unit with convection heat feeding,

nonuniformity of the withering process, which adversely affects the product
quality. For intensification of the process of tea mass withering by achieving
the uniform withering, a rational method of simultaneous treatment of tea
leaves with vibrations and the products with hot air from bottom upwards was
chosen. By theory, there were derived differential equations of the motion of
tea leaves on the vibrating surface and the equation determining the critical
