The analysis of methods for assessing the properties of contact pairs "hard alloy tool - steel workpiece" with the aim of improving the reliability of the choice of turning modes in generations of CNC systems equipped with technical intelligence. The models for calculating the cutting speed, the cutting force, the value of roughness Ra, have been corrected by introducing into their structure an additional informative value about the properties of each contact pair - the thermoEMF of the trial cut.

EXPERIMENTAL INVESTIGATIONS OF THE INFLUENCE OF SCREENS AND PROTECTIVE EQUIPMENT ON THE LEVEL OF ACOUSTIC SIGNAL IN A ROOM WITH GLASS AND METAL PLASTIC

In the digital stage of world development, information is constantly expanding its facets. That is why the exchange of information is a leading component of constant change in life. Although humanity is gradually moving to the use of electronic technology, acoustic information still plays a key role in information circulation. This applies to official communication in public institutions up to the highest level, business contacts in commercial structures and private communication between people. The process of transmitting information in acoustic form has dangerous consequences. The use of appropriate devices, such as directional acoustic microphones or technical intelligence acoustic antennas, which may be outside the scope of the information activity, makes it possible to obtain unauthorized information that should not reach third parties. Therefore, the task of detecting and protecting information leakage channels, including acoustic ones, is gaining a new degree of importance every day. The protection of the premises or building, where acoustic information regularly circulates, provides a set of organizational and technical measures and means of protection of information circulation, taking into account the peculiarities of the location and arrangement of the object. This study involves the study of the dependence of the level of the acoustic signal on ways to prevent leakage of information through the acoustic channel, which includes vibration noise by means of technical protection and coverage of improvised materials (shielding) of enclosing structures of information activities (OID). The experiment determines the degree of influence of density, sound-absorbing properties of materials and their combinations on acoustic oscillations, the source of which is in the OID. The object of the study was a basic room, where the enclosing structures are walls with windows and doors, ceiling and floor. It is also worth noting that the acoustic signal measurements were not performed in complete silence, which directly affected the accuracy of the results. This step was taken in order to best reproduce the conditions in which criminals often work.

A necessity of establishing the law for oneself

In the information age, social development trends clearly show that a person endowed with technical intelligence is somehow alienated from his own existence and is spiritually empty and "kinless". In this paper, we focus on this most difficult problem. The pathos of our discussion is as follows: understanding and sharing the difficulties of existence is the most reliable and unmistakable way of human self-knowledge and self-exaltation. In any historical section, a legal entity including an individual, nation, country, or world community, is obliged to verify the veracity of this path. Especially we need it from the perspective of our troubled but at the same time "successful century". It is obvious fact that in the twenty-first century, in the age of technical civilization, humanity fights to save human lives - in an unusual and unexpectedly difficult situation caused by COVID-19. A few years ago, we could never ever imagine that the world would "stop". We would believe that noisy traffic between states would stop, movement within countries would slow down, people would be forced to stay at home, meetings with each other would become dangerous, and due to lack of vaccine, millions of people would die. What are we dealing with? How can we overcome the most difficult challenges caused by co-existence with COVID? How do we evaluate what’s going on? It is difficult, extremely difficult to answer these questions, but the most difficult conditions are forcing us to find reasonable answers to such questions.

EXPERIMENTAL STUDIES OF THE STAND OF SIMULATION MODELING OF LASER MICROPHONE OPERATION FOR REMOVAL OF ACOUSTIC INFORMATION

He who possesses information owns the world. This statement is becoming more relevant every day. It is information that has become a tool for modern management and development. Therefore, the role of information technology is also constantly growing along with the risk of their malicious use. Attackers use all possible methods and means of technical intelligence to use potentially possible and create new types of information leakage channels to intercept it. object of information activities. Such oscillations caused by a certain speech (acoustic) signal can be intercepted by means of long-range intelligence. Most often, a laser microphone is used as such. The essence of its action is to emit a laser on the surface of the selected OID, which circulates a speech signal that creates sound vibrations on this surface. The movement of the surface leads to the modulation of the wave by phase, which is manifested in the variable nature of the sound signal Doppler shift of the frequency of the received signal. Often, such a surface is the glass of the windows, which reflects the beam to the receiver, to which is connected a detector that can reproduce the sound from the OID. This study aims to study the dependence of the laser microphone on such factors as: the location of the radiation source and the beam receiver from the membrane; membrane surface material; receiver type; materials of fencing constructions OID. The goal is to create a stand to demonstrate the operation of a laser microphone. The research process is carried out on a smaller scale, which is why an improvised room in the form of a cardboard box was chosen as the OID. Available tools were used to reproduce the operation of the laser microphone, so a laser pointer was chosen as the illuminator, and devices such as a solar panel, a light sensor and a signal amplifier microphone were used as the receiver. The study of the influence of selected factors was performed by measuring the voltage and volume of the acoustic signal using a multimeter and a certified program on the tablet, respectively.

The CIA and the (First) Persian Gulf War

Spying on secretive dictatorships is difficult. Saddam Hussein’s Iraq was, in the run up to the first Gulf War, a very hard target. This chapter examines how the CIA tried to overcome this problem. It examines the US’s engagement with Saddam Hussain and Iraq from the 1970s, and considers how the CIA understood Saddam following his rise to power in 1979. It culminates with Desert Storm, and how a mix of technical intelligence collection and analysis changed opinions about the likelihood Iraq invading neighbouring Kuwait.
