• Fault-tolerant control method of fuzzy logic system based on decision tree algorithm
  by Wei Zhao, Feng Gao 
  Abstract: In order to improve the reconstruction effect of fault parameters in fault tolerant control process, a fuzzy logic system fault tolerant control method based on decision tree algorithm is proposed. The linear model of the system is constructed by decision tree algorithm, and the fault model is constructed by adding fault cases. Then the system fault is detected and the influence of different fault parameters on the system is judged. After designing the fault-tolerant controller of the system, the cooperative variable is used to compensate the fault parameters until the output value of the system is restored to the normal condition, so as to complete the fault-tolerant control. Experimental results show that the reconstruction curve of fault current is more consistent with the theoretical value, which proves that the method improves the accuracy of the reconstruction value of fault parameters and makes the system run more stably.
  Keywords: decision tree algorithm; fuzzy logic system; fault tolerant control; cooperative variable; parameter compensation.

  by Qian Cao 
  Abstract: Aiming at the problems of low prediction accuracy and long prediction time in traditional methods, an enterprise financial data leakage risk prediction method based on ARIMA-SVM combination model is proposed. According to the financial data security risks existing at all levels of the enterprise, build the enterprise financial data leakage risk prediction index system and obtain the prediction indexes, including the two first-class indexes of application security and system security, the second-class indexes such as foreign cooperation security, and the third-class indexes such as the identification of sensitive data. Empirical mode decomposition is used to remove the noise data of prediction index, and the data after noise removal is input into ARIMA-SVM combination model, and the output of the model is the prediction result of data leakage risk. The simulation results show that the prediction accuracy of the proposed method is between 95%~100%, and the prediction time is within 16 s.

• Reliability Analysis of the Financial Management Auxiliary System of Remote Branches Based on Cloud Computing  
  by Suhong Bi 
  Abstract: Aiming at the problem of low system reliability caused by poor recoverability and robustness of traditional remote branch financial management system nodes, a reliability analysis of remote branch financial management auxiliary system based on cloud computing is proposed. J2EE cross platform architecture is adopted to store a large amount of unstructured data in the cloud platform, and classify, retrieve and access control the data. The self immune recovery algorithm of fault data nodes based on cloud computing technology is used to calculate the delayed recovery degree of nodes, so as to improve the reliability of financial management auxiliary system. After experimental analysis, the system recovers nine fault nodes, which is highly consistent with the distribution of standard samples, and the robustness of the system remains above 95%. It can be seen that the financial management auxiliary function of the system designed in this paper has good reliability.

• SYSTEMATIC ANALYIS OF AN UNRELIABLE BATCH SERVICE RETRIAL QUEUEING SYSTEM WITH TWO SORT OF VACATION  
  by NIRANJAN S.P, NIRANJAN S.P, INDHIRA K, INDHIRA K, CHANDRASEKARAN V. M, CHANDRASEKARAN V. M 
  Abstract: This paper concentrates on bulk arrival and batch service retrial queueing system with server failure, two types of vacation and constant retrial rate. If an arrival of customers finds a server is free then batch service will be provided with minimum of one customers and maximum of b customers. On the contrary, if the arrival of customers finds the server is busy then entire customers will join in the orbit to explore service again. After service completion, if there are no customers in the orbit then the server leaves for working vacation. During working vacation, the server provides service in lower service rate compared to regular service rate. In the working vacation completion, if the orbit size is zero then the server leaves for non-working vacation. The server may get failure in working period. If the server got failure with probability () then the renewal of service station will be considered. On the other hand, if there is no breakdown and orbit is empty then the server leaves for working vacation with probability (1 ). For this designed queueing model probability generating function of the orbit size will be obtained. Various performance measures are also be derived with suitable numerical illustrations.
  Keywords: working vacation; non-working vacation; constant retrial rate; renewal time.

• Predicting Code Beauty with Machine Learning Model  
  by Ermira Daka 
  Abstract: Software maintenance is one of the most expensive phases of the software development life cycle. This cost increases more when maintenance is performed on poorly written code. There exist a set of code writing patterns that developers need to follow to write good looking code. However, coding that conforms to rules is not always possible. During software evolution, code goes through different changes, which are the main reasons for breaking the rules of beautiful code. In this paper, we propose a machine learning (ML)-based model which will measure the beauty of a written code. The model built on a set of ten code-based features is learned using logic regression algorithm and is able to predict how beautiful is given peace of code. Furthermore, the model is evaluated using an empirical study, which shows that it has a moderate agreement with developers about the beauty of the code.
  Keywords: machine learning; code beauty; software maintenance.

• The design of library resource personalized recommendation system based on deep belief network  
  by Min Fu 
  Abstract: Aiming at the problems of low accuracy and user satisfaction of traditional library resource recommendation system, this paper designs a library resource personalised recommendation system based on deep belief network. Firstly, the architecture of library resource personalised recommendation system is designed and real-time recommendation module is added. For the real-time recommendation module, the probability function of the best resource in the deep belief network is obtained by combining several limited Boltzmann machines and maximum likelihood principles. The bias value and weight of the visible layer and the hidden layer of the deep belief network are corrected by the contrast divergence method to make the recommendation result more accurate. The experimental results show that the recommendation accuracy of the system can reach more than 97%, the recall rate can reach 92.5%, and the user satisfaction is more than 94.8%, indicating that the system has effectively improved the recommendation effect.

• Response of Singly Reinforced Square Concrete Slab with Varying Standard Concrete Strength and Slab Thickness under Concentric Impact Loading: A Numerical Study  
  by S.M. Anas, Mehtab Alam, Faris A. Uriyar 
  Abstract: Damage evaluation and performance enhancement of the structures due to ever-rising malicious sporadic explosions, vehicular collisions, aircraft crashing, falling construction equipment, and rock/boulder impact from landslips are of considerable concern and thus generate sufficient interest to structural engineers and researchers. In this study, a square RC slab of normal strength concrete (30 MPa) provided with tension steel (0.88%) is modelled in ABAQUS/Explicit software and its investigation has been carried out under impact loading. Following validation, analysis is extended to study the effect of design parameters like slab thickness and concrete strength on the impact response of the slab without altering the cover concrete, percentage and yield strength of the reinforcing steel. Results show that higher-strength concrete in the slab marginally reduces the punching of the slab but enhances the flexural damage. Higher thickness of slab reduces concrete perforation but results in more cracking owing to a decrease in the steel percentage.

• Risk Investment Heuristics: Applied Systemic Review  
  by Diego Ozorio, Leandro Ferreira Pereira, Rui Gonçalves, Álvaro Dias, Renato Lopes Da Costa 
  Abstract: Investments in projects are judged with rational mathematical parameters. Risky projects can build or destroy companies, careers and fortunes. Being able to fully rationalise the intelligence of the investment judgement seems unlikely. To a greater or lesser extent, cognition interferes with the judges preference. But would it be possible to identify cognitive traits of the judges intelligence when deciding on corporate investments? The article makes a systemic literature review of the field on the judgement of corporate investments. The revision suggests that there are gaps in theories about the judgement of corporate investments, which should be solved.
  Keywords: heuristics; bias; judgement; risk; investments.

• Citizen’s risk perception in crises: A systemic approach to reducing social vulnerability in the prefecture of Attica, Greece  
  by Ioannis Drakos, Gregory Chondrokoukis 
  Abstract: Over the last decades, a series of unexpected catastrophic events, from the Islamic terrorist attacks, the coronavirus disease (COVID-19), to natural disasters due to extreme weather events that hit the European Union, made it clear that risk is an integral part of peoples everyday lives. Given that, in most cases, the Hellenic state and local authorities responsible for the discovery and recovery of the citizens affected by these catastrophic and fatal events do not seem to be able to react. Therefore the occupants have to take their fate into their own hands. Furthermore, the demographic, the social, the economic, and the environmental inequalities significantly increase the social vulnerability of a significant proportion of citizens who, due to the difficulty of state authorities to respond to their particularities, when an incident crisis occurs, easily understand that their chances of survival will decline significantly. This paper proposes an innovation to manage such situations.

• Explosive effects and blast load parameters: a review  
  by S.M. Anas, Shahbaz Akram, Mehtab Alam 
  Abstract: Recent explosion events throughout the world have drawn attention to the vulnerability of infrastructure to acts of terrorism. Blast-resistant design of structures is treated as a specialised area to which, commonly, structural engineers are not exposed comprehensively, and most of the knowledge about the blast-resistant design of structures remains limited to military setups. This article presents an abridged review of explosive effects, namely blast from bare explosives in the air, air blast and ground shock from surface bursts, ground shock and cratering from buried explosives, TNT equivalency, fragment impact effects, wave propagation mechanism, and existing empirical estimations for blast pressure, the arrival time of blast wave, and positive phase duration. This study is useful to structural engineers and researchers for the blast analysis of structures.

• Discounting for proactive decision making in systemics  
  by Constantinos Artikis, Panagiotis Artikis 
  Abstract: Proactivity constitutes a concept very significant to systemics and relevant practical disciplines. Decision making is a practical discipline strongly supported by the incorporation of proactivity. In consequence, proactive decision making is readily recognised as a valuable research activity on the evolution of systems. Moreover, proactive decision making is generally adopted as a particularly valuable process for improving the resilience of systems in environments of global, catastrophic, or existential risks. It is widely acknowledged that the development and application of discounting models facilitate the implementation of proactive decision making. The paper focuses on the incorporation of discounting in proactive decision making for operations of systems.

• Leadership and effectiveness: the case of public sector during the COVID-19 pandemic crisis period  
  by Grigorios Despoteris, Athanasios Kriemadis 
  Abstract: This paper aims to examine the leadership in the Greek public sector during the COVID-19 pandemic crisis period. Specifically, it reveals the dominant leadership style, using the full range leadership model. It also determines the overall degree of extra effort, effectiveness, and satisfaction. Finally, it identifies the relationship between each leadership style and leaders effectiveness, using correlation and regression analysis. The survey was quantitative and involved civil servants employed in various services. The results show that the dominant leadership style is transactional leadership and that transformational leadership has the strongest positive correlation with effectiveness. Given the virtual absence of research during the COVID-19 crisis period in Greece, this paper adds information to the theoretical field of leadership, which can improve produced services of the public sector.
