Published: February 2022

By introducing the Vehicle Routing, Scheduling & Dispatching Problem for Multiples Depot (VRSDP/MD) and the description of formalization, it is helpful to offer a solution to solve the complex situation in practical transportation problem. In order to decrease the influence of the problem, A computing model embodying Hierarchical Multiplex Structure to take shape with an object-oriented multiple paradigms (HIMS+ model) are put forward as a proposal. And HIMS+ is divided into three layers: the first layer is the system cost adjusting area, the second layer is formation area for the system state, and that, the third layer is decision-making area for the system optimization. Two methods of meta-heuristic and fuzzy inference are proposed as an optimality calculation for HIMS+ architecture. There are two types of 24 tank lorries in the metropolis of Japan (Tokyo area), where two types of experiments are scheduled for 3-day of actual order data. Experiments results show that the HIMS+ model increase acceleration by 10 percent and decreases fast by 75 percent compared to what experts predict. The HIMS+ model has become a very reliable computing architecture for the multi objective and multi constraint optimization to real world transportation problems.

Published: February 2022

In order to make up for the deficiency of traditional passive jamming, a new electronic jamming mode is proposed, which mainly absorbs electromagnetic waves. Firstly, based on the traditional interference corridor model of radar electromagnetic signal power attenuation, the absorber as a whole is analyzed and its interference mechanism is obtained; With reference to the idea of studying the electromagnetic characteristics of stealth metamaterials by Floquet port method, the electromagnetic simulation software HFSS is used to establish an electromagnetic model for simulation verification, and the scaled method is used to simplify the model. The experimental results are consistent with the theory, which shows that the interference mechanism and the interference simulation model are correct.
Numerical Applications of Conformal Mapping with Explicit Formulae Based on the Power Series Method
Authors: Ma Yaocai , Lu Aizhong , Cai Hui , Zeng Xiangtai
Published: February 2022

A general optimization method, based on the power series method, is presented for computing the conformal mappings with explicit expressions from: (a) the unit disc onto an infinite domain exterior of a closed Jordan curve, (b) the circular annulus domain onto a finite doubly-connected domain bounded by two closed Jordan curves, (c) the infinite domain bounded by two circular curves onto an infinite domain bounded by two non-circular closed Jordan curves. The unknown mapping functions are approximated by the power series method. The problem of solving the mapping function coefficients is transformed into the problem of determining the image points on the image plane by means of the least square method. Different from most of the previous optimization methods, the angles are set as the design variables rather than the mapping function coefficients in the paper. The influence of the terms of the series on the calculation accuracy is investigated. The successful applications of the proposed method are shown by a large number of numerical examples.

Published: February 2022

This paper established a one-dimensional model of a coaxial dielectric barrier discharge (DBD) with a single dielectric layer covering the high-voltage electrode. The mixture of Ar and a small amount of CH4 was used as working gas, the influence of different voltage amplitude on the discharge characteristics was studied by 10.0 kHz microsecond pulsed power. The simulation results show that the discharge current curve presents bipolar characteristics with different intensities are generated in a single microsecond pulse period, and the primary discharge is much intense. The discharge current, discharge power can enhance by increasing the discharge voltage amplitude. The equivalent capacitance Cg also increases, the discharge voltage has no significant effect on Cd. In the experiment, it can be observed that the number of discharge filaments in the discharge gap increases with the increase of voltage amplitude, and photoionization is formed near the anode. The result of the current experimental trend is almost the same as the simulated current.
Seismic Scattering Wave Field Imaging Method Based on Convolution Neural Network and Equivalent Training Model
Authors: Xi Xian , Huang Jiangqing
Published: February 2022

The inversion of scattered waves in seismic exploration is a hot and difficult problem in related fields. We propose a hypothesis: the local wave field near each point on the wave field profile has a relationship with the minimum distance between that point and each scatterer, and this relationship can be recognized by a convolutional neural network (CNN). Based on this, the designed CNN can steadily classify and identify the scattered wavefield point by point, and realize the inversion imaging of the scatterer. We propose a new method of inversion imaging of scattered wavefield based on CNN and equivalent training model. The new method transforms the optimal inversion problem of the scatterer into the optimal design problem of the equivalent training model. Through the equivalent training model constructed by a parameterized method, the wavefield inversion and scatterer imaging of two different layered random cave media models are well realized, and the scattered wave imaging of the wavefield of the Marmousi2 model synthesis data is also realized robustly. The use of Bayesian discriminant imaging improves the resolution of the inversion results and helps interpreters quickly and accurately locate the scatterers.

Published: February 2022

To realize the roller forming process of curved edges of aluminium alloy auto-body closure panels, a numerical simulation method is proposed for the roller forming of aluminium alloy sheet with adhesive in flat variable curvature. Firstly, the motion of the roller is calculated by the discrete variable curvature curve method. Secondly, a numerical method of FEM-SPH coupling is established to simulate the interaction between the adhesive layer and the sheet. Subsequently, a numerical simulation model for the roller forming of aluminium alloy sheet with adhesive in flat variable curvature was constructed and finite element calculations were carried out. The simulation results show that the motion posture of the roller matches that of the actual roller, and the adhesive layer can adequately fill the inner and outer panel areas during the rolling process, which proves the effectiveness of the method.

Published: February 2022

With the continuous progress and development of robotics, mobile robots have been widely used in many different fields. In the power grid, mobile robots are used to inspect electrical equipment, which greatly reduce the investment of manpower and material resources. However, in many cases, mobile robots need to work in a constantly changing and complex environment. Because they cannot obtain environmental information in time, it is often difficult to make path planning. In response to this problem, this paper proposes a path planning method for mobile robots based on improved reinforcement learning. This method establishes a grid environment model, defines the return value through the number of steps of the robot, and then proposes a changing action selection strategy for the balance between the robot’s exploration and utilization of the environment in reinforcement learning, so that the exploration factor dynamically change with the increase of the robot’s exploration degree of the environment, thus speeding up the convergence speed of the learning algorithm. Simulation results show that this method can realize autonomous navigation and path planning of mobile robots in complex environments. Compared with traditional algorithms, it greatly reduces the number of iterations.

Authors: Lu Xinggan , Jiang Kun , Cheng Shenshen , Wang Hao
Published: February 2022

For gas generators based on pyrotechnic technology, as the structure becomes more complex, the internal ballistic characteristic is no longer just related to the flow field generated by propellant combustion. The fluid-structure interaction in the system plays an important role. In order to accurately predict the internal ballistic characteristic of the gas generator, a mathematical model of coupling the flow field generated by propellant combustion and the structural evolution in the system is established. The interior ballistic model is utilized to calculate the flow field generated by propellant combustion, and the finite element method is applied to simulate the structural evolution. The flow field and the structural evolution are coupled through a user subroutine interface in ABAQUS. The accuracy of the coupled model is verified by experiment, and the precision of the traditional classical interior ballistic model is compared with that of the coupled model. The results show that the pressure prediction error of the traditional classical interior ballistic model is more than 46% for gas generators with complex structures. While the coupling model is in great agreement with the experiment, and the error of pressure prediction is less than 5.0%.

Published: February 2022

In the current complex economic situation, production enterprises are facing manyuncertainties. Reasonable planning of the ordering and transportation of raw materials to ensure the stable operation of the production supply chain is the key to the sustainable development of enterprises. In this paper, a TOPSIS model based on entropy weight and a raw material ordering and transportation model for production enterprises based on multi-objective programming are proposed to provide reference for raw material ordering and transportation selection of production enterprises. In this model, the supply characteristics of suppliers are quantitatively analyzed, and on the basis of the demand of production enterprises, the supplier is determined based on the principle of minimum number of suppliers. Then, the future transshipment loss rate of the transporter is predicted based on the time series, and then the corresponding transporter and transshipment scheme are determined with the lowest loss rate as the target. The research on the model of suppliers and transporter has a good guiding significance for the ordering and transportation of raw materials in manufacturing enterprises.

Published: February 2022

When public emergencies or disasters occurred, such as fires and earthquakes, safety accidents with group trampling can easily be caused. In the previous work, the study of crowd evacuation mainly adopted artificial parameters for simulations. To overcome these problems, we propose a data-driven crowd evacuation simulation method based on Raspberry Pi. First, we configure Raspberry Pi as sensor node, which is connected the wireless WiFi network card with monitoring function and the infrared sensor module with detection function. And then the sensor node was deployed to collect real data of crowd evacuation in real scenarios. Second, the curve fitting method is used to deal with the functional relationship between crowd density and average evacuation speed. In terms of crowd evacuation simulation calculation, we present Crowd Density-based Reciprocal Velocity Obstacle (CD-RVO) algorithm which drive individual speed changes with crowd density, to optimize the options for safety exit of individuals and reduce evacuation time effectively. Finally, the experimental results show that the proposed method can simulate the process of crowd evacuation realistically and improve crowd evacuation efficiency.

Published: February 2022

At present, in the actual big data HDFS environment, because a large amount of data is stored locally, it is necessary to optimize the data security and transmission rate. At present, there are two main problems in HDFS. The background cluster is mainly divided into management process and business process. Therefore, in the actual use process, because the management process only has the main and standby dual machine backup, all the All the services of HDFS need to query the metadata through the namenode of the management end of HDFS, which leads to the emergence of hot spots, blocking the transmission link and increasing the load pressure of the equipment. In addition, the design concept of HDFS is that the underlying hardware is not reliable, which leads to the definition of three copy mechanism for data storage. The underlying device has already sacrificed part of the space (between 2 / 3-1 / 2) through raid data protection. When the data is protected through the triple copy mechanism, it will lead to too many data storage samples, which is not conducive to the actual storage space Use.This paper introduces the architecture and storage strategy of big data HDFS, and puts forward several solutions and ideas for the existing problems.

Published: February 2022

In order to accurately predict the acid dew point of coal-fired power plant boiler flue gas and seek a more suitable formula for calculating the acid dew point of flue gas in actual production, the least square method is used to compare the common acid dew point calculation formulas based on relevant test data. And obtain the acid dew point calculation formula based on sulfur trioxide. The fitting formulas of Taylor and Xiang Boxiang’s data tables were obtained by fitting and compared with common calculation formulas. The results show that the calculation form of Verhoff&Branchero calculation formula is more suitable for the simulation of acid dew point calculation formula based on sulfur trioxide. Together, Taylor’s calculation formula has a wider range of values and is more suitable for field applications, But when the sulfur trioxide concentration is lower than 20ppm, the Haase calculation formula has higher calculation accuracy.

Az erdő- és vegetációtüzek okainak megértése kiemelkedő jelentőségű az erdőtűzmegelőzési tevékenység, valamint a környezet- és lakosságvédelmi intézkedések megtervezésében. Hazánkban a klimatikus viszonyok és a vegetáció összetétele miatt természetes úton alig keletkezik vegetációtűz. A vegetációtüzek többsége emberi gondatlanság következménye. A tűzkockázat értékelésének hatékonyságát növeli, ha értjük a vegetációtüzek okait, a tüzet gyújtó személyek motivációit. Az erdőtűz megelőzésért felelős hatóságok a 2011–2020 közötti időszakban végzett adatgyűjtése során megismert tűzokok elemzésével lehetőség van a magyarországi vegetációtüzek antropogén eredetének vizsgálatára, a szocioökonómiai faktorok meghatározására, ami a későbbiekben alapja lehet a vonatkozó célzott kommunikáció célcsoportjai meghatározásának. Az Európai Erdőtűz Információs Rendszer tűzkeletkezésiok-sémájával való összevetés alapján javaslatok tehetők a hazai rendszer harmonizálására.

Published: February 2022

In this research, the Servperf method is used to analyze the quality of health and safety services. The main purpose of this article is to determine the quality level of preventive health and safety services provided in the workplaces within the framework of the perception of the employees who benefit from these services. The questionnaire prepared in accordance with the Servperf method was applied to 412 employees working in various sectors, and the results were classified according to age, gender, education level, sector, and the way of providing (internal & external) services. Descriptive statistics were used in the evaluation of results. The total perceived Servperf score of the health and safety services was 2.84, medium level. As the age and education level of the employees increases, the satisfaction level and Servperf scores of the service quality decrease. The satisfaction score of the construction workers is significantly lower than the other sectors. Satisfaction levels of employees in the workplaces where services are provided internally are higher than those of the workplaces offering external sources. Despite legal regulations related to preventive health and safety services, accidents have not decreased in Turkey. The quality of the service provided by external health and safety units is significantly low. Competition arising from the marketization of occupational health and safety services reduces the quality of the service provided. For these reasons, the number of research aimed at determining the quality of these services should be increased both in Turkey and in the world.

Published: February 2022

Delay in construction projects, especially in road and highway projects, is a universal phenomenon. Afghanistan construction industry is no exception. There are factors causing delays in the Afghanistan construction industry which have negative effects on the key project stakeholders and the project’s deliverables and outcomes. This research aims to identify the causes of delays that affect highway and road projects in Afghanistan and to provide recommendations in order to minimize or control delays in such projects. This will help, in return, facilitate and improve the delivery of roads and highways projects in Afghanistan. To achieve this aim, the study sets out to achieve the following objectives: 1) to determine the most important causes of delay that affect road and highway projects in Afghanistan, 2) to identify the severity of the delay causes from clients’ and contractors’ perspectives, 3) to investigate the differences and discrepancies between clients’ and contractors’ opinions and views, and based on first three objectives, 4) to finally provide recommendations for minimizing and/or controlling delays in road and highway projects, to improve the status-quo and to facilitate procurement/delivery of road and highway projects in Afghanistan. Causes of delay were gathered upon conducting a critical literature review of different types of construction, in different countries. An expert interview and a questionnaire survey formed the basis of this paper, listing 29 important causes of delay in such projects. The major causes of delay then were categorized into three groups following main stages of the highway projects, namely: 1) preparation, 2) procurement, and 3) implementation. The questionnaire survey was distributed to 100 construction participants and 79 were received who represent the government in road projects and contractors. Relative importance index (RII) was calculated and according to the highest values the top ten delay causes of road projects in Afghanistan were determined. Spearman correlation index was used to assess the correlation of causes and groups between clients and contractors. The findings of the study revealed that the top 10 significant factors causing a delay in road projects in Afghanistan are; security (war, theft, kidnapping, etc.), shortage of equipment and material or financial status of contractors, land acquisition, corruption in the procurement process, progress payment delays by owners/clients, non-consideration of security risks in the procurement process, Inaccurate design and bills of quantities, insufficient contractors’ experience, poor qualification of the contractors’ technical staff and award project to lowest bids. The findings will help clients and contractors to mitigate or prevent delays in road and highway projects in Afghanistan. Finally, to help overcome delays in road and highway projects more effectively, recommendations have been made for fundamental reforms in procurement systems for major projects.

Alexa – What’s Your Personality? The Personification Of Amazon’s Alexa Through Television Advertisements
Authors: Serman Ariella
Published: February 2022

Brand personification has been widely used in marketing strategies for decades, and many research studies have confirmed its efficacy in shaping consumers’ brand attitudes and behaviours. The aim of this research paper is to explore how voice-activated virtual assistants are personified in commercial advertisements. Previous research has investigated why artificial intelligence-powered devices are personified; however fewer scholars have explored how these devices are anthropomorphized in commercial advertisements. Considering that advertisements are a “contribution to the complex symbol which is the brand image” (Ogilvy, 1951, p. 178), it is useful to study how brands advertise their products with the goal of influencing consumers’ positive perceptions of the brand. This paper analyzes four Super Bowl commercials for Amazon’s virtual agent, Alexa. I consider how language, characters, voice, and other visual elements contribute to the personification of Alexa and attempt to deduce the implication of this advertisement strategy for consumer brands. Considering that voice activated virtual assistants are a rapidly growing consumer technology, this study expands the extant knowledge on how these agents are anthropomorphized, and what this means for the consumer-brand relationship.
A Scientist and a Comedian Walk Into a Bar: Humour’s Role in Science Communication
Authors: Larney Andrea
Published: February 2022

The art of communicating science to non-scientists (e.g., policy makers, lay-audiences) is the challenge faced by science communicators. Not only is it vital that scientific information leave the realm of academia to be put into action, but the goals of science communication increasingly include public engagement with science. Traditional tactics for public engagement have faced roadblocks in terms of being accessible and actually engaging to a broad audience. Communicators have thus identified that non-traditional techniques, such as adding humour, may make scientific information more accessible. In this MRP, I investigate the use of humour as a creative communication tool to engage the public with science in informal settings. I analyze 34 episodes of a funny science podcast, The Infinite Monkey Cage, to identify how humour is used, and by whom (e.g., scientists, non-scientists). I identify potential roles of common humour types and humour usage styles, as well as the role of each author type. These findings may serve to aid future humorous science communication endeavors, as well as to guide future research.

[Para. 1 of Summary]

It’s not a stretch to say information technology services have become near-essential in North America today. On
average we now connect to more than 22 applications daily and generate two GB of data while we’re at it, says
Salam Ismaeel, a PhD candidate at Ryerson in the Department of Computer Science. “More than 77 percent of
today’s businesses,” he adds, “rely on the Internet and data center resources.”
Factors of architecture efficiency of Ukrainian institutes of budgetary system

The article aims to broaden the theoretical and methodological foundations and scientific substantiation of approaches to improving the efficiency of institutional structure of the budget system Ukraine on the basis of high-quality institutional support for its formation and functioning.
This study is based on systemic and evolutionary approaches that provide a comprehensive understanding of the institutional structure of the budget system. The institutional architecture improvement requires identifying various characteristics, direct relations and feedback as well as dependencies that arise in the formation of budget policy of Ukraine.
The study deals with appraisal of the degree of perfection of the architecture influence on and institutional order, the budget process and the budget system efficiency. The practical importance is determined by the fact that theoretical and methodological provisions, conclusions and practical recommendations make the scientific basis for developing a new holistic concept of forming the institutional order of the budget system in terms of its decentralization. The analysis shows that the degree of perfection of the architecture and institutional architecture of the budget system significantly affects the efficiency of the budget process. It changes the philosophy of public finance management and creates incentives for dominance in the public choice of the Putnam group (those who care about public needs) rather than Olson (those who think primarily about their own needs). The study has noted some problems of control over the budget funds use depending on the society maturity.
Conclusions on the ability of the budget system perfect architecture and institutional order to direct the potential of inclusive markets to welfare improvement, to implement innovations and invest them in people requires the state to consider them critical to economic growth and nation's wealth. The budget system must be organically integrated into the overall system of governance and be fully accountable and transparent in the new institutional order with inclusive economic and political institutions.
Keywords: institutional order, institutional environment, market institutions, budget, budget process, formal and informal institutions.

Research on competence and its effect on performance and job satisfaction is relatively rare. Included that is still rarely done is research on the effect of competence according to PerMenPANRB Number 38 of 2017 on performance and job satisfaction. This study also analyzes the effect of competence on ASN job satisfaction and places job satisfaction as a mediating variable of competence on ASN performance. Respondents in this study were PPSDM employees of the Ministry of Finance. The results showed that managerial competence had a direct and significant effect on work goals and performance of PPSDM employees. Work objectives have no direct and not significant positive effect on employee performance. In addition, activities do not mediate the effect on employee performance.

Abstract:Garbage is a leading problem polemic that always exists in the surrounding environment, with the amount of garbage the more pollution that causes disasters, one of which is flooding. Garbage itself is divided into organic waste and non-organic waste. Organic waste itself can be processed into compost, while non-organic waste can be recycled, one of which is handicrafts. The purpose of this research is to create an android-based application that is used to provide information and procedures for recycling waste. The method used is RAD, namely planning, design, and implementation. The results obtained in this study are an application that contains information that can be used by the community in recycling waste.

Currently, most portable cosmetics devices are single assistant skincare function products, which lack long-termusing motivation because of unable to inspect using history and limit to use a single function. Nowadays people chase scientific evidence to inspect self-related products and customizer their demand. In the project, we provide a portable multifunction device combined detection sensor with two physiotherapy functions. We developed the algorithm and digital filter for the MCU and smart devices to algorithm the data through detecting currents by four probes completely contact on the skin. Otherwise, we integrated immediately replenish micro-particle water function using aerosol variable-frequency transport technology and three wavelengths LED phototherapy to provide all domains of skin conditioning. All the detection data, environmental information and using history will record by the developed APP.

Este trabalho objetivou analisar as mudanças de uso e cobertura vegetal do município de Vigia e avaliar o Índice de Vegetação da Diferença Normalizada-NDVI em uma área de transição de cerrado e vegetação secundária no mesmo município. Apresentando duas escalas diferentes, uma a nível municipal e a outra análise foi a nível local. A classe Pastagem apresentou aumento, passando de 107 km² em 1985 para 108 Km² em 2018, perdendo área para as classes Urbana e Vegetação Secundária, 9,85 km² e 60,43 Km², respectivamente. A Classe de Vegetação Secundária apresentou um aumento de 32,92 Km², passando de 161,13 Km² em 1985 para 194,05 Km² em 2018, sendo a principal contribuição da classe de pastagem com 60,43 Km². A classe de Cerrado apresentou uma diminuição expressiva, no ano de 1985 o município de Vigia apresentava 9,85 km², diminuindo para 4042 km² no ano de 2018, perda de 5,42 Km² de área de Cerrado, perdendo para classes de urbano, pastagem e vegetação secundária. Concluindo que o monitoramento de uso e cobertura das da terra torna-se importante para as áreas consideradas de não floresta como o Cerrado, principalmente no bioma Amazônia, pelas características peculiares de transição entre Cerrado e outros tipos de vegetação, pois com o monitoramento é possível detectar degradações e desmatamento, contribuindo dessa forma para a gestão de políticas públicas voltadas para a preservação da biodiversidade dessas áreas.
