“…In an extended sense, personnel security is a set of mechanisms, methods, techniques that ensure the protection and effectiveness of bodies for the development of business infrastructure from threats of destructive professionalism, unprofessionalism, increasing the number of people who have personal or corrupt ties to obtain their own benefits, etc. (Wang, Chang, Cui, 2019).…”

Personnel is the main resource, potential, the basis for the formation of the entire state administration apparatus, and therefore play an important role. The quality of reforms, the quality of the public administration system, as well as the formation of a positive image of the state depend on the quality, professionalism, continuous development of personnel and human resources. The purpose of the article is to analyze the activities of the state in the context of protecting personnel security, depending on the quality of their regulation and control of corruption in the business environment. The research is based on theories of human resources' management in business environment development institutions and theories of public administration, which make it possible to form new knowledge about the integration of management control concepts into the practice of human resources' management. The results of the research can be used in public authorities. The formed regression equation of public administration efficiency is estimated depending on the quality of the regulatory environment and the level of the fight against corruption in countries with economies in transition with a high level of adequacy, and a corresponding analysis is carried out. The research takes place in the field of public administration and is aimed at protecting the business environment from the corruption component by developing personnel security. The author's contribution consists in a comprehensive analysis and systematization of data from various sources of information. In the course of the study, the method of theoretical research and systematization was used, which made it possible to form data in the most convenient way and draw appropriate conclusions.

“…In recent years, active terahertz (THz) imaging ranging from 0.1 to 10 THz has received increasing attention in the fields of security screening, aerial imaging, medical diagnostics and non-destructive testing [1,2]. THz imaging modalities offer non-ionizing radiation and can operate in all-weather conditions [3]. Although visible and infrared frequencies can provide very high resolution, they cannot penetrate through some materials such as clothing.…”

“…They are also used for imaging purposes. Imaging at millimetre-waves (mmW) has many applications such as security screening [1][2][3], automotive radars [4,5], coincidence imaging [6], autonomous robotics [7][8][9], remote sensing [10][11][12], and concealed weapon detection [13][14][15]. In comparison to optical modalities, mmW signals can penetrate most optically opaque materials and operate in all-weather conditions.…”

There is an increasing demand in real-time imagery applications such as rapid response to disaster rescue and security screening to name a few. The throughput of a radar imaging system is mainly controlled by two parameters; data acquisition time and signal processing time. To minimize the data acquisition time, various methods are being tried and tested by researchers worldwide. Among them is the computational imaging (CI) technique, which relies on using coded apertures to encode the radar back-scattered measurements onto a set of spatio-temporally incoherent radiation patterns. Such a CI-based imaging approach eliminates the requirement for a raster scan and can substantially simplify the physical hardware architecture. Equally important is the processing time needed to retrieve the scene information from the coded back-scattered measurements. In CI, the simplification in the hardware layer comes at the cost of increased complexity in the signal processing layer due to the indirect mapping and compression of the scene information through the spatio-temporally incoherent transfer function of the coded apertures. To address this particular challenge, this paper presents a hardware-based solution for CI signal processing using a Field Programmable Gate Array (an Xilinx Virtex-7 (XC7VX485T) FPGA chip) architecture. In particular, the proposed method consists of calculating the CI sensing matrix using the FPGA chip and storing it on the FPGA platform for image reconstruction. For the adjoint operation, the calculated sensing matrix is applied on the measured back-scattered waves from the target object. We demonstrate that the FPGA based calculation can reach 21.9 times faster speed than conventional brute-force solutions.
