Abstract: Satellite antennas are constructively shaped like an
irradiator and a reflector. Satellite antennas with a single irradiator
placed in the focus of one parabola operate at one frequency. Some
satellite systems operate at two frequencies of different ranges. Is it
possible for two irradiators working on a cross-band to work
together on one reflector? In this case, a whole antenna structure is
saved.
The answer to the question is given in this article. Measurements
and analysis of the results of three different irradiators were made
in real conditions. For the high frequency, a standard low-noise
converter is selected. For the low frequency three different beam
constructions are selected. Measurements are made on a real Earth
- Satellite - Earth track.

Abstract: The article shows the need for a systematic
approach in the analysis and evaluation of the state of complex
objects of various types. A systematic approach to the analysis
of complex date objects the opportunity to find new ways to
optimize the resources of these projects.
The main goal of the system approach is physically
implemented by a number of software tools. In the proposed
work, as a tool for the implementation of the systems
approach, it was proposed to use the methodology of functional
modeling IDEF0. This approach allowed us to create a
functional model of the object to determine the function of
each element and at the same time visualize its structural
features. Methodology IDEF0 is actively used for the analysis
and design of technological processes. In this paper, the
authors proposed using technology IDEF0 to describe and
analyze the interaction of resources for such a complex object
as the human body.
There is a decomposition of several levels in this work. In
the form of blocks presents the main functions of the simulated
object. These functions are broken down (decomposed) into
composite parts and presented in the form of more detailed
diagrams. The situation continues until the object is described
at the level of detail necessary to achieve the objectives of a
particular study. The top level diagram provides the most
general or abstract description of the functioning of the human
body. This chart is followed by a series of diagrams that give a
more detailed picture of the main subsystems of the body.
Using decomposition, the human body was divided into
main subsystems. A mathematical model is proposed for one of
the subsystems of the organism. This model is tested for
adequacy. And it can be used to describe the output of this
subsystem from the state of homeostasis.

Abstract: Medical psychological diagnostics is a relatively
new interdisciplinary branch of clinical psychology that has
developed in recent years. It combines problems and objectives
of at least two areas of knowledge and practice: psychological
diagnostics and medicine. Measurement (as finding of measure,
that is, the ratio of quantity and quality of an object) involves
the use of different scales, at least, quantitative and qualitative,
and the result is, as a rule, a quantitatively expressed value, even
though the value is measured on the basis of qualitative ordinary
scales. But it should be noted that in medicine, primarily in
psychiatry and clinical psychology, there are no scales of their
own, and classical metrological scales are borrowed. Thus, the
question arises about the correctness and permissibility of
transformations of results obtained by indirect measurements
using such scales. The problems and questions raised in this
publication reflect only part of the difficulties that arise in
medical psychodiagnostics as an industry that deals with
measurement of non-physical quantities, alienated products of
brain activity and do not cover even deeper phenomena.

Abstract: In recent years science needs to embrace digitization as
one of the methods of reproduction of scientific knowledge.
Thus emerges the question about the possibility of using nonphysical
quantities and related psychological phenomena.
Methods of mathematical modelling are at the basis of
digitization, they are employed to describe certain
phenomena, to analyze and forecast the changes within them.
The success and priority of the creation of mathematical
models is additionally justified by the inherent strict elegance,
which also makes it possible to obtain completely unexpected
solutions based on statistics processed with specified
algorithms.
“Research conducted by mathematicians represents
beautiful and elegant abstract mathematical systems. It is art,
which way of expression is using ideas.”
However, the problem of data mining in measurement of
psychological phenomena, as well as principles and rules of
their analysis (for developing adequate mathematical models)
are under-represented in the most of scientific researches.

Abstract: With the introduction of the new definition of the kilogram,
the last definition of a base unit based on a physical artefact is
sent to history. This change will not affect directly the life of
ordinary citizens, but it will have a huge impact on the work of
the National Metrological Institutes (NMI) in the long term, and
on the Bulgarian Institute of Metrology (BIM) including.

Abstract: At Temperature Measurements Department of the
National Center of Metrology, BIM the standard in the field of
calibration of relative humidity is a Precision Dew Point
Hygrometer, which is included in an Automatic Relative
Humidity Calibration System with temperature camera and flow
type generation of the moisture gas.
Review of relative humidity (RH) measurements requires:
- Traceability of reference standards
- The inputs with known contribution to uncertainty
- Validated procedures
- Uniformity of the chamber environment
- Multiple RH and temperature calibration points
Calibration and Measurement Capabilities (CMC’s) for
Relative Humidity of Temperature Measurements Department,
National Center of Metrology (NCM), BIM were adopted in 2016
and in 2017 they were published in Appendix C of the KCDB.
A brief review and description of the measurement techniques,
apparatus used and important points of uncertainty budget are
given in this paper.

Abstract: The article suggests the use of a systematic
approach in management by using well-known management
schools and areas of achievement at the same time. The article
touches on the essence of the concept of synergy, and that
synergy exists only in such a system that performs its functions.
On its basis, a hypothesis has been proposed for identifying
synergy, and in the processes themselves a systematic approach
has been proposed to identify phenomena such as synergy. It is
proposed that the source of synergy might be “entropy”. The
author of the article indicates that processes take place in any
activity of a human beings and society, such as the humanities,
social and economic sciences, which implies the existence of
entropy, which is very similar to the theory of transactions and
transaction costs. This approach is necessary for the
application of budgeting and financial relations for individual
entities and as well as the whole state.
