Gennadiy Kamyshentsev, Tetiana Tiahun, Olga Shevchenko DEVELOPMENT OF THE CONTROL ALGORITHM OF THE INFORMATION AND TECHNICAL METHOD OF ACOUSTIC CONTROL OF THE EMERGENCY OF THE TERRORISTIC HYSTERISTIC In the work on the basis of the analysis of vulnerability of objects of critical infrastructure, the structural scheme of the control algorithm of the information and technical method of acoustic control of emergence of an emergency situation of terrorist character on objects of critical infrastructure of Ukraine is developed. It is proved that the main task of the process of managing a terrorist emergency at a critical infrastructure facility is to prevent intruders from entering a protected facility by detecting and terminating their actions in a timely manner. At the same time, the range of control of detection means located on the protected object is limited to several kilometers. The use of acoustic information from external surveillance systems located at traffic interchanges, in satellite cities, controlled areas of private structures and its analysis of events occurring in the thirty-kilometer zone, will allow the collection of everyday factors to detect in advance the signs of terrorist emergencies. nature, which will significantly increase the effectiveness of the entire system of physical protection of the protected object. Accordingly, the control algorithm of the information and technical method of acoustic control of terrorist emergencies at protected critical infrastructure by integrated use of acoustic control systems within the perimeter and approaches to it consists of nineteen blocks located at seven levels. connected by logical connections, and provides distribution of data on the fixed video and audio images, their binding and identification, creates conditions for detection of hostile and obviously hostile actions against the protected object, provides registration of deviations in behavior of people , in the use of transport and other phenomena, which as a result of careful systematization of the obtained data allows to identify signs of preparation of a terrorist act against a protected object and further prevent the development of an emergency situation or prevent its spread. Key words: emergency situation, acoustic control, information and technical method

Over the past few years, the importance of video surveillance in securing national critical infrastructure has significantly increased, with applications including the detection of failures and anomalies. Accompanied by the proliferation of video is the increasing number of attacks against surveillance systems. Among the attacks, False Frame Injection (FFI) attacks that replay video frames from a previous recording to mask the live feed has the highest impact. While many attempts have been made to detect FFI frames using features from the video feeds, video analysis is computationally too intensive to be deployed on-site for real-time false frame detection. In this paper, we investigated the feasibility of FFI attacks on compromised surveillance systems at the edge and propose an effective technique to detect the injected false video and audio frames by monitoring the surveillance feed using the embedded Electrical Network Frequency (ENF) signals. An ENF operates at a nominal frequency of 60 Hz/50 Hz based on its geographical location and maintains a stable value across the entire power grid interconnection with minor fluctuations. For surveillance system video/audio recordings connected to the power grid, the ENF signals are embedded. The time-varying nature of the ENF component was used as a forensic application for authenticating the surveillance feed. The paper highlights the ENF signal collection from a power grid creating a reference database and ENF extraction from the recordings using conventional short-time Fourier Transform and spectrum detection for robust ENF signal analysis in the presence of noise and interference caused in different harmonics. The experimental results demonstrated the effectiveness of ENF signal detection and/or abnormalities for FFI attacks.

The use of video surveillance systems is used in the areas of security, law and order, in the territories of protected objects, in monitoring the movement of road vehicles and in other areas. The main disadvantage of a video surveillance system is its susceptibility to weather influences (rain, fog, snowfall, etc.), which degrades the quality of the video system by reducing the signal level. Therefore, the urgency of finding new ways and possibilities to improve the quality of video signals is one of the priority areas of signal processing. The main task of this work was to determine the main parameters, simulate the transmission line and amplifier, and select the schematic diagram of the transmitting and receiving path with the voltage and current ratings. Both the receiver and the cable video transmitter have different means of adjusting to different transmission line lengths. The signal at the output of each receiver should be in the range from 0.9 to 1.1 V, and the spread of the total ohmic resistance of the wires of the video transmission line at the input of the receiver should be no more than 2 – 3%. Based on these parameters, the equipment is configured for transmitting video over the channel. The magnitude of the mismatch is regulated by potentiometers, which allow smooth adjustment of the video transmission equipment [1]. As a rule, video transmission over the channel is carried out at a distance of 50 to 1500 m. If it is necessary to transmit video at distances less than 50 m, additional resistances are connected in series at the receiver input so that the total line resistance is 30 - 50 Ohm [1].

This article reviews the key considerations when managing a patient with a difficult airway. The difficult airway may be anticipated from preassessment allowing time for investigations and preparation. Alternatively, the unanticipated difficult airway can present in an emergency situation, or unexpectedly during a routine anaesthetic. The main airway management techniques are discussed with a description of their advantages and limitations. Current guidelines are included that demonstrate how the techniques are incorporated into an overall strategy with a plan A–D when failure occurs. It is critical to progress through such an algorithm in a timely manner to prevent the onset of hypoxia.

ObjectiveTo explore the difference between the reported date of admissionand discharge date using discharge messages (A03), from hospitalemergency departments participating in the Louisiana Early EventDetection System (LEEDS.IntroductionThe Infectious Disease Epidemiology Section (IDEpi) within theOffice of Public Health (LaOPH) conducts syndromic surveillanceof emergency departments by means of the Louisiana Early EventDetection System (LEEDS). LEEDS accepts ADT (admit-discharge-transfer) messages from participating hospitals, predominately A04(registration) and A03 (discharge), to obtain symptom or syndromeinformation on patients reporting to hospital emergency departments.Capturing the data using discharge messages (A03) only could resultin a delay in receipt of data by LaOPH, considering the variability inthe length of stay of a patient in the ED.MethodsEmergency department data from participating hospitals isimported daily to LEEDS and processed for syndrome classification.IDEpi syndromic surveillance messages received for the period ofCDC week 1632 and 1636 (8/8/16-9/8/16) using MS Access andExcel to calculate the difference (in days) between the reported admitdate and discharge date in A03 messages.Results88.1% of the A03 messages submitted in the 4 week analysisperiod exhibited no delay (delay=0 days) between the admit date andthe reported discharge date, compared to only 10.7% showing a delayof one day (delay = 1 day) and 1.06% showing a delay of 2 days ormore (delay≥2 days). Less than 0.2% of the messages had missinginformation regarding discharge date (Table 1).ConclusionsSyndromic surveillance systems operate under a constant need forimprovement and enhancement. The quality of the data, independentof the quality of the system, should always strive to be of the highestpedigree in order to inform disease-specific programs and detectpublic health aberrations. In order to identify these potential concerns,it is imperative that the data be submitted to public health agenciesin a timely manner. Based on this analysis, the lapse in time betweenadmit and discharge results in little to no patient syndromic data delayfor those hospital ED’s that exclusively send A03 messages. Thisstatement is supported by the finding that close to 99% of messagesdemonstrated a delay between admit date and discharge date of oneday or less.Table 1.

In the paper is considered synthesis of the controller with tachometric feedback with feed forward compensation of disturbance torque, velocity and acceleration errors. It is difficult to obtain the desired control performance when the control algorithm is only based on the robot dynamic model. We use the neural network to generate auxiliary joint control torque to compensate these uncertainties. The two-layer neural network is used as the compensator. The main task of control system here is to track the required trajectory. Simulations are done in MATLAB for RzRyRy robot minimal configuration.

Cascade Type

Landfills taking into account current trends in the placement of innovative liquidation technologies on their territory with a variety of energy-intensive technological equipment pose an additional technogenic danger. This requires a set of measures to prevent emergencies of the cascade type of distribution, due to the shift of the slope of the waste masses with the subsequent explosion of biogas. Analysis of existing approaches to modeling the conditions of solid waste landfills proves the lack of comprehensive studies to assess the effectiveness of solid waste landfills in the case of the introduction of additional technological energy-intensive technological equipment. In the course of the work the author considers the physical conditions of emergency prevention at the landfill in the conditions of a separate task of involving liquidation energy-intensive technological equipment. Depending on the location of the specified equipment in relation to the landfill, emergencies of cascade type may occur due to the shift of waste masses with the subsequent explosion of biogas. In the course of the work the author developed a control algorithm for the implementation of a mathematical model of cascade type emergency prevention at solid waste landfills with liquidation energy-intensive technological equipment due to loss of stability of the slope of the waste array to landslide followed by biogas explosion. The control algorithm consists of 18 analytical blocks, which are located on two levels and are interconnected by direct and feedback. In order to further practical application of the control algorithm, it is necessary to develop an appropriate methodology, the implementation of which should effectively counteract the emergency situation with priority consequences, such as the number of victims, the number of deaths, the number of people with impaired living conditions.
