Originality/value: This manuscript portrays a broader assessment of the available literature for data duplication along with the classification of different methods for the data storage used in the different level of storage of hospital wastewater data collection.
A network model of operational actions of emergency rescue teams in the elimination of the consequences of emergency situations in a graphical and mathematical representation has been developed. The use of the model makes it possible to plan or analyze the process of organizing operational actions of civil protection units, to manage the course of its implementation. This is relevant for the planned period of emergency response. The task of forming performers of individual works in the elimination of the consequences of emergency situations has been formulated. The essence of the task is reduced to the ability to choose from a variety of civil protection units the necessary performers and assign them to work. Moreover, upon the appointment, the entire complex of works was completed within a given deadline and with minimal costs. Formalization of the corresponding problem made it possible to bring it to the classical assignment problem, which is solved by Kuhn's method. The use of a dynamic pro-gramming algorithm made it possible to obtain an initial approximation of the solution of the problem, at which the cost of performing a complex of emergency rescue operations will be minimal. To optimize the network graph of operational actions by reducing the length of the critical path, a dynamic programming method is proposed. The research results are synthesized into an algorithm. The implementation of the algorithm is to consistently clarify the assignments of performers to work. This makes it possible to determine the minimum costs for the implementation of the rescue plan within a given time frame (if such a solution exists), as well as to estimate the minimum time for carrying out emergency rescue operations for a given set of possible performers.
Обґрунтовано необхідність розроблення високоефективної технологій утилізації авіаційних бомб та способу визначення зон безпеки при утилізації відповідних авіаційних засобів ураження. Для вирішення поставленого завдання застосовано системний підхід, в межах якого використовувались наукові методи узагальнення й порівняння, аналізу і синтезу, методи математичного моделювання тощо. Для обґрунтування ефективних рішень щодо забезпечення безпечних умов організації робіт запропонований спосіб визначення зон безпеки при утилізації авіаційних засобів ураження, який дозволяє врахувати фугасну та уламкову дію авіаційних засобів ураження під час їх детонації. Для приблизного оцінювання ступеню ураження об’єктів використані узагальнені емпіричні дані, відповідні закони ураження, які представляються у вигляді залежності ймовірності ураження від параметрів, що характеризують вплив, – надлишкового тиску на фронті ударної хвилі, питомого імпульсу ударної хвилі. Практично реалізовано твердження, що надлишковий тиск та питомий імпульс є функціями маси енергоносія (вибухової речовини) та відстані до центра вибуху, що дозволяє перейти від параметричного закону ураження до координатного закону ураження. Перехід від розрахунків до графічного зображення здійснюється за допо-могою співвідношень, які пов’язують параметри вибухової хвилі з величинами відстані та тротилового еквіваленту. Під час розрахунків врахована можливість ураження об’єктів (людей) від дії уламків, що розлітаються. Для цього використаний закон зміни швидкості уламка на траєкторії. На підставі проведених розрахунків параметрів зон дії небезпечних факторів вибуху авіаційних бомб зроблені відповідні висновки щодо характеристик зон безпеки під час утилізації авіаційних засобів ураження. Запропонований спосіб визначення зон безпеки реалізує математичний апарат, який дозволяє співвідносити енергоносій до тротилового еквіваленту і може використовуватись в якості консервативної оцінки необхідної для експрес-аналізу стійкості об’єктів за умови їх розміщення в середніх і дальніх зонах від джерела вибуху
Purpose: The conducted research was aimed at constructing a structural and functional model for the interaction of bodies providing aviation safety during crisis management. Design/methodology/approach: The methods of mathematical simulation and the graph theory, the methods comparison and formalization have been applied to study the process of interaction between the bodies assuring aviation safety. Using methods of the linear algebra allowed constructing a mathematical model for the functional structure of the interaction process that contains description of this process by the main methods of interaction. Findings: It has been proved that the interaction process has a certain functional properties that reflect the functional relations between the modes of violator actions, the modes of using the response forces and the modes of interaction. A structural and functional model of interaction in semantic, algebraic forms and in the form of graphs has been created. using typical operations with incidence matrices, the possibility of obtaining the physical interpretation of the simulation results within the introduced algebra of functional structure models has been justified. Research limitations/implications: Discusses interactions between the bodies that assure aviation safety and at the same time, the possibility of a crisis situation is taken into account. Practical implications: The developed models allow reflecting the current state of the functional system and the elements of the process of interaction rather completely. It makes a structural and functional analysis of interaction possible and allows defining the priority directions of its organization, simulating the options and methods of interaction in solving relevant tasks by the bodies that assure aviation safety. Originality/value: That allowed not only describing the formal relations between the methods of interaction and interacting units, between the interacting units and the modes of violator actions, but also considering the influence of the interaction process on the current state of the functional system.
Purpose: To evaluate the superpave design performance using Epolene (EE-2) as modifier, since SUPERPAVE design is a modified and sophisticated aspect as compared to previous mix design for asphalt mixtures. This is primarily due to the fact that superpave design mix also takes into consideration properties of materials beside asphalt. Design/methodology/approach: This study was conducted using Epolene (EE-2) as modifier in order to evaluate the performance of SUPERPAVE suitability for construction of roads in Alfaraa campus (King Khalid University) Abha, in Asir Province of Saudi Arabia. Glow number test, dynamic modulus test and indirect tensile strength test were conducted to evaluate the performance of EE-2 modifier against the control mixture. Findings: The mixture modified with EE-2 gave better performance in terms of temperature-based performance and resistance to moisture damage. Also, larger values of E*/sinφ were obtained for EE-2 modified mixture at various loading frequencies and temperature in comparison to control mixture. Research limitations/implications: The Epolene modifier successfully enhances and improves the SUPERPAVE mixture performance. Further studies are required to evaluate the performance of EE-2 modifier at much lower temperature ranges. Practical implications: The results of the study allow us to recommend the investigated asphalt mixture for applied for the construction of roads in the Alfaraa (new campus of King Khalid University), Abha, Asir province, Saudi Arabia. Originality/value: A modified asphalt mixture has been proposed that has better performance at higher and lower temperatures. The developed asphalt mixture is more resistant to moisture damage than the compared to control mixture.
