Modeling of operating modes of woodworking equipment

The effective use of the production capabilities of logging and woodworking equipment largely depends on the compliance of their design features and work organization parameters in specific production and technical conditions. This is achieved in the process of technological calculations with the determination of the optimal modes of their functioning. The paper proposes a methodology and results of modeling on analytical models when sawing logs. The proposed method consists in the fact that in order to maintain stocks at the calculated level, eliminate downtime of machines with the highest productivity in operations with a lower productivity, the duration of their operation is increased by the time calculated for specific conditions. As a result of the work, the analysis of methods and models of timber inventory management was carried out. The main features of woodworking production and its technological process are given. It has been established that the technological process is a production line of mixed aggregation with flexible connections.

Efficient use of the insurance sector potential adjusted for its shadowing: Case of Ukraine

The insurance sector plays a critical role in the economy, providing protection and security of the state and influencing its social and economic development. However, having a significant potential for development, the sector cannot fully realize it due to many problems, including its shadowing. Using the method of unprofitable enterprises analysis, which is applied by the Ministry for Development of Economy, Trade and Agriculture of Ukraine to determine the level of the shadow economy, considering the type of economic activity, the level of shadowing of the insurance services sector in Ukraine and its regions in 2013 and 2018 was calculated. The calculation results showed an increase in the shadow level of the insurance services sector both in Ukraine as a whole and in the separate regions. To evaluate the effectiveness of the insurance sector potential, given the calculated level of shadowing, a comprehensive assessment was carried out by standardizing the values of selected indicators characterizing the potential of the insurance sector in the context of Ukraine’s socio-economic development. The indicators of the efficient use of the insurance services sector potential in Ukrainian regions, calculated using an integrated assessment, showed an increase in the efficiency of using the potential of the insurance sector in three out of five analyzed regions. Zaporizhzhia region demonstrated the most significant growth. It has been proven that an increase in the volume of services provided is a key factor in increasing the social and economic efficiency of the insurance sector.

Safe RPAS integration in non-segregated airspace

Purpose This paper aims to assess the implications in safety levels by the integration of remotely piloted aircraft system (RPAS). The goal is to calculate the number of RPAS that can jointly operate with conventional aircraft regarding conflict risk, without exceeding current safety levels. Design/methodology/approach This approach benchmarks a calculated level of safety (CLS) with a target level of safety (TLS). Monte Carlo (MC) simulations quantify the TLS based on the current operation of conventional aircraft. Then, different experiments calculate the CLS associated with combinations of conventional aircraft and RPAS. MC simulations are performed based on probabilistic distributions of aircraft performances, entry times and geographical distribution. The safety levels are based on a conflict risk model because the safety metrics are the average number of conflicts and average conflict duration. Findings The results provide restrictions to the number of RPAS that can jointly operate with conventional aircraft. The TLS is quantified for four conventional aircraft. MC simulations confirm that the integration of RPAS demands a reduction in the total number of aircraft. The same number of RPAS than conventional aircraft shows an increase over 90% average number of conflicts and 300% average conflict time. Research limitations/implications The methodology is applied to one flight level of en-route airspace without considering climbing or descending aircraft. Originality/value This paper is one of the most advanced investigations performed to quantify the number of RPAS that can be safely integrated into non-segregated airspace, which is one of the challenges for the forthcoming integration of RPAS. Particularly, Europe draws to allow operating RPAS and conventional aircraft in non-segregated airspace by 2025, but this demanding perspective entails a thorough analysis of operational and safety aspects involved.

Nuclear level density with proton resonance using Gaussian orthogonal ensemble theory

The Gaussian orthogonal ensemble (GOE) version of the random matrix theory (RMT) has been used to study the level density following up the proton interaction with 44Ca, 48Ti and 56Fe. A promising analysis method has been implemented based on the available data of the resonance spacing, where widths are associated with Porter Thomas distribution. The calculated level density for the compound nuclei 45Sc,49Vand 57Co shows a parity and spin dependence, where for Sc a discrepancy in level density distinguished from this analysis probably due to the spin misassignment .The present results show an acceptable agreement with the combinatorial method of level density.

How many RPAS can be safely integrated in non–segregated airspace?

The forthcoming integration of Remotely Piloted Aircraft System (RPAS) is one of the cmost omplex challenges for aviation. Europe draws to allow operating RPAS and conventional aircraft in non-segregated airspace by 2025, but this demanding perspective entails a thorough analysis of the different aspects involved. The RPAS integration in non-segregated airspace cannot imply an increase in the safety levels. This paper assesses how the RPAS integration affects safety levels. The goal is to regulate the number of RPAS that can jointly operate with conventional aircraft regarding conflict risk. This approach benchmarks a Calculated Level of Safety (CLS) with a Target Level of Safety (TLS). Monte Carlo (MC) simulations quantify the TLS based on schedules of conventional aircraft. Then, different combinations of conventional aircraft and RPAS provide different CLS. MC simulations are performed based on probabilistic distributions of aircraft performances, entry times and geographical distribution of aircraft. The safety levels are based on a conflict-risk model because the primary metrics are average number of conflicts and average conflict duration. The methodology is applied to one flight level of en-route airspace. The results provide restrictions to the number of RPAS that can jointly operate with conventional aircraft. Particularly, the TLS is quantified for four conventional aircraft and MC simulations provide the combinations of conventional aircraft and RPAS that fulfil the CLS. The same number of RPAS than conventional aircraft shows an increase over 90% average number of conflicts and 300% average conflict time.

THE IMPACT OF TRAFFIC DYNAMIC ON AIR QUALITY AND VULNERABLE OBJECTS NEAR BUSY STREET IN NOVI SAD

In this paper, the distribution of nitrogen dioxide originating from vehicles from a busy street in Novi Sad, located near residential buildings and kindergartens, was performed. Based on the calculated level of nitrogen dioxide emissions from the vehicle, as well as the most frequent meteorological conditions, simulation of nitrogen dioxide propagation was carried out using ADMS urban software. Considering that the street is a part of the bridge whose elevation is gradually increasing, this research reveals permanently and intense exposure of certain parts of the residential buildings. The results presented in this paper can serve as a useful basis for taking measures to reduce the impact of traffic on air quality and human health through urban planning particulary of vulnerable facilities.

The Optimization of Parameters of a Technological Tank Battery for Liquefied Petroleum Gas

Fuel-power supply systems are priority areas of engineering services. They account for large capital investments and costs of energy resources. An energy supply system based on LPG provides a high level of diversification and autonomy. This article presents recommendations for determining the basic technological parameters of liquefied petroleum gas tanks. The recommendation are intended to improve the efficiency of the tanks. The economic-mathematical model of optimizing underground tanks considers own evaporative capacity of tanks, their mutual thermal effect, as well as the temporal dynamics and unstable cost factors. The model allows for revealing the optimum technological parameters of installations: a single tank volume, the number of tanks in a group installation, the calculated level of gas tanks fill up before next refueling, depending on the volume of gas consumption.

Energies and radiative transitions (E1, E2, and M1) for hydrogen-like thorium

Hydrogen-like ions with high Z present unique opportunities to promote the understanding of atomic structure. On the other hand, determining the atomic structure of hydrogen-like atoms provides us the test of relativistic effects as well as accurate values of the spectral characteristics required for many applications. For this reason we have calculated level energies of hydrogen like thorium (Th89+, Z = 90) with both multiconfiguration Hartree–Fock (MCHF) and multiconfiguration Dirac–Fock (MCDF) methods. These calculations have contained the Breit–Pauli relativistic corrections in MCHF calculation and quantum electrodynamics effects in MCDF calculations besides electron correlations. The wavelengths, λ, weighted oscillator strengths, gf-value, and transition probabilities, Aki, have been also represented for allowed (E1) and forbidden (E2 and M1) transitions. We have compared our results with only theoretical work results because there is no available experimental data for Th89+.
