Caballero Galeote, L., and J. García Mestanza. "Qualitative Impact Analysis of International Tourists and Residents’ Perceptions of Málaga-Costa Del Sol Airport." Sustainability 12, no. 11 (June 9, 2020): 4725. http://dx.doi.org/10.3390/su12114725.
Full textAbstract:
Air transport plays a key role especially in countries where tourism has a great impact on the economy. In Spain, the contribution made by this industry to GPD stands at EUR 119 billion, representing 11% of GDP. This case study focuses on the Málaga-Costa del Sol Airport due to the growth the city has experienced in recent years. The research examines the impacts of this infrastructure from the perceptions of residents and tourists. We conducted 638 questionnaires and 50 interviews with residents, and 165 questionnaires and 106 interviews with international tourists from August 2019 to January 2020. A qualitative thematic analysis was carried out using the NVivo Pro software. The findings indicate that residents value the ease of travel and employment generated by the airport. However, they are concerned about the environment impacts and mass tourism. For tourists, almost no negative impacts are recorded. Residents and tourists consider the existence of positive effects on other nearby cities of Andalusia. Conclusions have practical and theoretical implications for impact researches.

Impulsionado pela problemática ambiental, que ora em muitos casos é conferida por ambientes de riscos e vulnerabilidades, o artigo que se segue tem como objetivo identificar, à luz da análise integrada do ambiente, os riscos e vulnerabilidades socioambientais na cidade de Picos/PI, além de servir como subsídio para um ordenamento territorial e governança do risco, sendo útil, por exemplo, para o Corpo de Bombeiros e a Defesa Civil no direcionamento das suas ações. Recorreu-se à Análise Integrada do Ambiente e ao Materialismo Histórico e Dialético, sustentados nos seguintes procedimentos metodológicos: leitura de bibliografia referente à temática (delineamento teórico-conceitual), observações in loco, levantamento fotográfico, mapeamento (por meio do software ArcGis 10.3) e de notícias de jornal. Os principais resultados apontaram cenários de riscos e vulnerabilidades (relacionadas à descaraterização do relevo e aos eventos de inundação do rio Guaribas) nas seguintes áreas: Centro, Canto da Várzea, Ipueiras, São José, Bomba, Aerolândia, Paroquial, Morros da Cidade de Deus, Morada do Sol e da Mariana. Tais áreas evidenciam a espacialização da população picoense em setores impróprios, fato esse intensificado pelo perfil socioeconômico dos seus moradores. Por fim, ressalta-se que os grupos sociais expostos aos riscos e vulnerabilidades possuem distintas capacidades de resiliência, tendo em vista o tempo de resposta diferenciado quanto ao enfrentamento dos riscos, sendo necessárias, assim, ações efetivas relacionadas à Defesa Civil e de avaliação de riscos dessas áreas frente aos eventos constatados neste estudo. Integrated analysis of the environment as a subsidy to identify socio-environmental risks and vulnerabilities in Picos/PI A B S T R A C TDriven by the environmental problem, which in many cases is conferred by risk and vulnerability environments, the following article aims to identify, in the light of the integrated environmental analysis, the socio-environmental risks and vulnerabilities in the city of Picos/PI, besides to serve as input for land use planning and governance risk and is useful, for example, the Fire Department and the Civil Defense in directing their actions. It appealed to the Integrated Analysis Environment and the Historical and Dialectical Materialism, sustained in the following methodological procedures: bibliography of reading on the subject (theoretical and conceptual design), on-site observations, photographic survey, mapping (through ArcGIS 10.3 software) and newspaper reports. The main results showed risk scenarios and vulnerabilities (related to relief decharacterization and the Guaribas river flood events) in the following areas: Centro, Canto da Várzea, Ipueiras, São José, Bomba, Aerolândia, Paroquial, Morros da Cidade de Deus, Morada do Sol and Mariana. These areas show the spatial distribution of population picoense in inappropriate sectors, a fact intensified by the socioeconomic profile of its residents. Finally, we emphasize that social groups exposed to the risks and vulnerabilities have different resiliency capabilities, in view of the time for each answer as to face the risks that are necessary, effective actions related to Civil Defense and risk assessment of these areas against the events observed in this study.

Full textAbstract:
The expediency of using the tools of visual-effective, visual-figurative and conceptual thinking for planning the purposeful activity of autonomous intelligent agents in problem environments of various degrees of a priori uncertainty has been substantiated. The content is revealed and the role of each form of thinking is shown in the process of automatic planning of the purposeful behavior of autonomous intelligent agents in the changing conditions of functioning. The special role of conceptual thinking in the performance of complex tasks by autonomous agents and the planning of polyphasic behavior associated with it is indicated. Taking into account the complexity of the problems associated with the formalization of mental acts of conceptual thinking, possible ways of its gradual development from the initial level to the transition to higher levels of development are shown, expanding on this basis the class of tasks solved by autonomous intelligent agents. A model of knowledge representation and tools for deriving solutions of the initial level of conceptual thinking have been developed, which allow intelligent agents to break down the tasks they receive into sub-goals of behavior. Then, on this basis, plan polyphase activity by searching for solutions to the associated subtasks, which ensure the determination of the minimum length routes of movement in a prob lematic environment with obstacles and the purposeful manipulation of objects in it. The tools are synthesized allowing to establish the order of elaboration of complex actions included in the structure of the task formulated by autonomous intelligent agents. It is shown that the further development of the proposed methodological foundations for constructing intelligent problem sol vers is associated with the formalization of a higher level of mental acts of conceptual thinking, which make it possible to solve practical problems of different complexity, formulated both in procedural and declarative form of presentation in the form of various target situations of the problem environment, having a large dimension.

Full textAbstract:
In this study an investigation has been conducted on the effect of reduced graphene oxide (rGO) coating on increasing the value of Lithium Ferro Phosphate (LFP) electrical conductivity. This coating process uses a variation of the mass ratio of LiFePO4/rGO by 90%:10%, 70%:20%, and 67%:33%. The LiFePO4 precursor was prepared using the sol-gel rute from the main commercial materials, namely Li2CO3 powder as a source of lithium ions, FeCl2.4H2O as a source of iron and NH4H2PO4 powder as a phosphate source. As for the coating used rGO extracted from coconut shell waste. The samples were calcined with temperature variations of 600°C, 650°C and 700°C in an argon environment for 10 hour. The phase purity and crystal structure of LiFePO4 were analyzed using XRD. The analysis of data from XRD was done using the the Match!, Rietica, and MAUD software. Based on the results of XRD analysis, LiFePO4 with high purity and good crystallinity was obtained when the sample was calcined at temperature of 700°C. The results of the MAUD analysis show that the best size of LiFePO4 crystal is 86,54 nm. LiFePO4/rGO nanocomposite was successfully synthesized by mechanical ultracentrifugation method. The characterization of the value of electrical conductivity, carried out using a four-point probe. The results show that the greater the percentage of rGO, the higher the value of electrical conductivity. The mass ratio of 67% LiFePO4 and 33% rGO shows an increment in good conductivity values, from the original order of 10-8 S/cm to the order of 10-4 S/cm.

Full textAbstract:
The optimal design of a building and city, including the balance of their energy performance, must include requirements from a wide range of areas, especially electrical engineering, informatics, technical equipment of buildings, construction and architecture, psychology and many other fields. It is the optimal design, simulation and modelling that are most reflected in the energy requirements of buildings while meeting the requirements of energy sustainability. The impact of buildings and cities on the environment is crucial and unmistakable. It should be emphasized that an inappropriately (architecturally or technologically) designed building with state-of-the-art control technology will still have worse properties than an optimally designed building without a control system. This inspired us to design a building energy model (BEM) with the implementation of a Smart Grid in a decentralized sustainable energy system, which is a microgrid from renewable energy sources (RES). This inspired us to conduct an analysis of simulation models (simultaneous simulations) to show the possibility of their application in the process of fully satisfying energy needs in a given urban region. The main goal is to design an original methodology for the design of smart “Nearly Zero Energy Buildings” (NZEB) and subsequent energy sustainability solutions. This led us to use Hybrid Optimization of Multiple Energy Resources (HOMER), PV*SOL (2D solar software design tool for the photovoltaic system performance), Monte Carlo and DesignBuilder. The EMB was designed based on the Six Sigma design quality management methodology. In the process of integrating Smart Grids with energy efficiency solutions for buildings, an original optimization basis was designed for smart buildings and smart urban areas. The proposed EMB was verified in an experiment.

Full textAbstract:
This article discusses an express control method that allows in situ measurements of the thermal conductivity of insulation materials. Three samples of the most common thermal insulation materials, such as polyurethane, extruded polystyrene, and expanded polystyrene, were studied. Additionally, optical and organic glasses were investigated as materials with a stable value of thermal conductivity. For the measurement of thermal conductivity, the express control device, which implements the differential method of local heat influence, was used. The case studies were focused on the reduction of fluctuations of the measured signals caused by different influencing factors using wavelet transform. The application of wavelet transform for data processing decreased the thermal conductivity measurement’s relative error for organic glass SOL and optical glasses TF-1 and LK-5. The application of wavelet transform thermal conductivity measurement data for polyurethane, extruded polystyrene, and expanded polystyrene allowed to reduce twice the duration of express control while maintaining the same level of measurement error. The results of the investigation could be used to increase the accuracy in express control of the thermal conductivity of insulation materials by improving the data processing. This approach could be implemented in software and does not require a change in the design of the measuring equipment or the use of additional tools.

Full textAbstract:
The Mataloko geothermal system in Ngada-Flores Regency, East Nusa Tenggara, is located in three active volcanic mountains (Inerie, Ebulobo, and Inielika). The contribution of high levels of CH4 and exhaust emissions of SO2 due to its utilization as a geothermal power plant (GPP) impacts the environment. This study aims to analyze and spatially model the distribution and impact of SO2 and CH4 gas levels in the Mataloko GPP area. The quantitative descriptive method was used through direct measurement at gas wells and laboratory testing. The results showed a tendency to increase SO2 levels in the MT-4 gas-well with levels of 8.00 ppm exceeding the quality standard, which could disturb the environment in the Mataloko-GPP area. Impact of high SO2 will experience dry sediment because it is not combustible in the air, then it will drop slowly to be absorbed by soil and plants. Droplets of acid gas blown by the wind and left on trees and buildings are even inhaled into the breath. In addition, the advantages of model with surfer 12 software can help identify the distribution of SO2 and SO4 emissions in the generating area.

With the rapid development of economic globalization, more and more complex products have to be designed by the cooperation of the designers in different geographic locations. The effective sharing and deployment of collaborative design software are of great significance to enhance the capability of cooperative research and development of products. To solve the problem of software integration for collaborative design in the distributed and heterogeneous environment, a distributed software integration framework for collaborative product design based on Service Oriented Architecture (SOA) was proposed. Based on Web Service technology, a collaborative design platform was built, which encapsulates the functions of Computer Aided Design (CAD), Computer Aided Engineering (CAE), Product Data Management (PDM) and Enterprise Resource Planning (ERP) software to integrate distributed collaborative design software in heterogeneous environment.

Full textAbstract:
Computer Systems on Integrated Software Platforms are gaining popularity among users. They have a number of advantages over other platforms. In particular, this is a reduction in maintenance costs and the ability to quickly deploy additional Hardware & Software without stopping the system. But there are also a number of disadvantages. The most significant of these is an increase in the processing time for transactions of users using data warehouses. One of the directions of its solution is the formation of resource distribution, which is focused on minimizing resource costs. A mathematical model of resource distribution during transactions in CS on ISP is proposed. The distribution quality is determined by the criterion of minimizing the total transaction execution time. The admissible set of distributions is formed using the method of penalties for the execution of transactions. This further refines the integrated infrastructure. Simulation modeling of the process of distributing a computing resource with a selected plan made it possible to formulate requirements for the algorithm for solving the problem of scheduling transactions in an integrated environment. The proposed method also makes it possible to carry out operational rescheduling of transaction execution and reduce time costs when making operational changes to the transaction execution plan.

Full textAbstract:
Service Oriented Architecture (SOA) uses a structural approach to create services which can be reused and shared. SOA provides agility and cost saving in software development, transforming vertical applications to various software components, which can be reused in applications. Cloud computing expands the software service accessibility and usage via Web services. To move successfully into cloud computing, an architecture supporting the cloud capabilities is needed. The cloud provides a good platform for deploying Web services based on SOA. Customer satisfaction, improved collaboration, enhanced end-to-end user security and end-user authentication, and business growth are some long term benefits supported by modern technologies in both of cloud computing and SOA. The objective of the paper is to study the effective process and effort required to design and implement a SOA based system development methodology and applying it to construct a u-Healthcare system to provide healthcare services including accessing medical records of patients on a universal end-to-end basis.

Full textAbstract:
This article reports the ongoing work on an environment for hardware-in-the-loop (HIL) and software-in-the-loop (SIL) tests of CubeSats and the benefits gained from using such an environment for low-cost satellite development. The satellite tested for these reported efforts was the MOVE-II CubeSat, developed at the Technical University of Munich since April 2015. The HIL environment has supported the development and verification of MOVE-II’s flight software and continues to aid the MOVE-II mission after its launch on 3 December 2018. The HIL environment allows the satellite to interact with a simulated space environment in real-time during on-ground tests. Simulated models are used to replace the satellite’s sensors and actuators, providing the interaction between the satellite and the HIL simulation. This approach allows for high hardware coverage and requires relatively low development effort and equipment cost compared to other simulation approaches. One key distinction from other simulation environments is the inclusion of the electrical domain of the satellite, which enables accurate power budget verification. The presented results include the verification of MOVE-II’s attitude determination and control algorithms, the verification of the power budget, and the training of the operator team with realistic simulated failures prior to launch. This report additionally presents how the simulation environment was used to analyze issues detected after launch and to verify the performance of new software developed to address the in-flight anomalies prior to software deployment.

Full textAbstract:
In recent years, most cities have faced great demand for electricity supply due to rapid population growth and industrialization. Supplying sufficient electrical energy, while reducing greenhouse gas emissions, is one of the major concerns of policymakers and scientists all over the world. In Saudi Arabia, local authorities are increasingly aware of the necessity of reducing the environmental impact of nonrenewable energy by exploring alternative sustainable energy sources and improving buildings’ energy efficiency. Recently, building-integrated photovoltaic (BIPV) technology has been regarded as a promising technology for generating instantaneous sustainable energy for buildings. To achieve a substantial contribution regarding zero energy buildings, solar energy should be widely used in residential buildings within the urban context. This paper examines how to achieve an appropriate model for integrating photovoltaics on the rooftop of residential buildings in Hail city to provide alternative energy sources. The estimated rooftop areas in Hail city, utilizable for PV application were calculated. Using PV*SOL simulation software, the performance ratio and the system efficiency, as well as the annual energy output in several tilt angles, were determined and presented. The amount of energy expected when using all effective roof area in the city was also calculated. The amount of CO2 emissions that could be reduced as a result of using a PV system was estimated. The results show a significant area of rooftop suitable for PV system in residential buildings in Hail city, which exceeds 9 million square meters. On the other hand, the performance ratio and the system efficiency are affected by the tilt angle of the PV module, where the efficiency increases with higher tilt angle, this is due to the PV module temperature, where, with the decrease in the PV module temperature its efficiency increases. The results indicate that the 30° tilt PV produced the highest amount of energy, whereas the 75° tilt PV records the smallest one although it achieves the best possible efficiency. There is a significant amount of energy produced from the use of all residential rooftops in Hail, and there is also a significant reduction in the amount of CO2 emissions. It is expected that this research would develop innovative building design strategies and specifications allowing for better climate and energy efficiency as well.

Full textAbstract:
Reliability and safety for hardware in computer systems have been sufficiently studied in recent years. On the other hand, a safety-related system (SRS) for software has not been assured with the proper method of calculating the software safety integrity level (SIL) in the functional safety standards, which is currently determined only by the number of development methods applied to practical safety-related system (SRSs). In this paper, we discuss quantitative assessment for it by applying quantitative measures based on software reliability growth models (SRGMs) that have been widely and successfully applied to practical software quality management activities. Based on a nonhomogeneous Poisson process (NHPP), the plausible methods of calculating software SIL in the functional safety standard are proposed. Further, we discuss the quantitative method for assuring software SIL based on the optimal release policies with the test cost during testing-environment and the risk cost after the software products will be released.

Full textAbstract:
There are various methods being used to model and study behavior of electromagnetic (EM) waves in controlled source electromagnetic (CSEM) environment. Sea Bed logging (SBL) is using CSEM technique in detecting and characterizing hydrocarbon bearing reservoirs in deep water areas. It uses a mobile horizontal electric dipole (HED) source called transmitter that transmits low frequency of 0.1Hz to 10Hz, 30m - 40m above sea bed and an array of seafloor electric field receivers. These signals depend on the resistivity structure beneath the sea bed as hydrocarbon is known to have high resistivity value of 30 500 Ωm in contrast to sea water layer of 0.5 2 Ωm and sediments of 1-2 Ωm. Array of seafloor receivers detect EM energy that propagates through the sea and subsurface. Data collected is used for processing and modeling purposes to predict depth of resistive bodies. In this paper, synthetics data generated from developed simulator that is able to replicate SBL environment is compared to synthetics data generated from Computer Simulation Software (CST) and COMSOL software with same parameter setting to study trends between them. Percentage differences between data with hydrocarbon and without hydrocarbon are calculated and comparisons are made. Overburden thickness is varied from 1000m to 3000m (incremented by 500m) at frequency of 0.125Hz. It was found that all the data generated either from simulator, CST software and COMSOL showing the same trends. From these findings it shall conclude that the simulator is a reliable tool to model any sea bed logging environment and predicting present of hydrocarbon reservoir in SBL environment.

Full textAbstract:
The presented research focuses upon the analysis of additional specific tools (namely translation memory (TM) technologies) of SDL Trados Studio 2017 and MemoQ Translator Pro 2017 automated translation systems and their application for translation of English-language instructions into Ukrainian. With the help of the above-mentioned software tools 60 English-language operating instructions for household appliances have been translated into Ukrainian (three projects were created in both systems, each containing 10 instructions). TM is a database consisting of segments of source text (sentences, paragraphs, headings, etc.) and translations of each of these segments. TM, used in both SDL Trados Studio and MemoQ Translator Pro systems, significantly improves the quality, speed, consistency and efficiency of each translation task. SDL Trados Studio 2017 and MemoQ Translator Pro 2017 compare content of the current segment of the source file with segments of the same language already contained in the TM. If the system finds a similar segment that is currently stored in the TM, it prompts the translator to use a ready-made translation. The degree of equivalence between the segment of the source document and the segment contained in the TM is expressed as a percentage. Thus, both software tools capture the cases of «Exact match», «Perfect match» and «Fuzzy match». SDL Trados Studio 2017 andMemoQ Translator Pro 2017 slightly differ in segment statuses and colour segment marking. Both systems do not make adjustments automatically, but their identification and navigation capabilities allow one to quickly correct such errors by hand. Unfortunately, the initial focus on the Russian-language market (and, consequently, on the Russian language system) has led to another peculiarity of automated translation into Ukrainian in SDL Trados Studio and MemoQ Translator Pro systems, namely a large number of stylistic errors that require quality personalized correction.

Full textAbstract:
Urban pollution has significantly contributed to the spread of diseases and global warming. The analysis of spatial distribution characteristics of atmospheric pollutants is crucial for making sustainable industrial policy, and environmentally friendly urban planning. In this paper, GeoDa software is used to analyze how sulfur dioxide (SO2), nitrogen oxides (NOx), and smoke dust (DUS) are spatially distributed in various provinces of China. Then, global spatial correlation test and cluster analysis are carried out to obtain the spatial evolution characteristics of three pollutants. Afterward, the spatial panel data model is applied to explore the factors that affect the spatial evolution of SO2, NOx and smoke dust (DUS) nationwide. MATLAB is used to estimate the Spatial Lag Model (SLM) and the Spatial Error Model (SEM) of the three pollutants, respectively. According to our analysis, SEM is more applicable for SO2 and NOx, whereas SLM is optimal for smoke dust (DUS). The results show that foreign direct investment (FDI), industrial structure, and urbanization aggravate environmental pollution, while per capita gross domestic products (per capita GDP) has a negative relationship with the cluster of pollutants. The study concludes by informing public policy makers on environment friendly policies for a more sustainable development.

Full textAbstract:
People nowadays spend more and more time performing collaborative tasks at anywhere and anytime. Specifically, professionals want to collaborate with each other by using advanced technologies for sharing knowledge in order to improve/automatize business processes. Semantic web technologies offer multiple benefits such as data integration across sources and automation enablers. The conversion of the widespread Content Management Systems into its semantic equivalent is a relevant step, as this enables the benefits of the semantic web to be extended. The FLERSA annotation tool makes it possible. In particular, it converts the Joomla! CMS into its semantic equivalent. However, this tool is highly coupled with that specific Joomla! platform. Furthermore, ambient intelligent (AmI) environments can be seen as a natural way to address complex interactions between users and their environment, which could be transparently supported through distributed information systems. However, to build distributed information systems for AmI environments it is necessary to make important design decisions and apply techniques at system/software architecture level. In this paper, a SOA-based design solution consisting of two services and an underlying middleware is combined with the FLERSA tool. It allows end-users to collaborate independently of technical details and specific context conditions and in a distributed, decentralized way.

Full textAbstract:
The experience of the Joint Forces operation (Anti-terrorist operation in Donetsk and Luhansk oblasts) shows that the current order of management of military radio communication systems does not always meet the modern requirements for them. The classic centralized approach to the management of channel and network resources of military radio systems does not quite meet modern requirements, so the authors of this article proposed to take mobile self-organizing networks as a basic principle of construction. The authors propose a comprehensive method of managing the parameters of military radio networks in conditions of uncertainty of the electronic environment, the essence of which is to ensure the maintenance of the specified values of the performance of military radio communication systems at the appropriate level. The article is based on the control principle, which is described in the reference network model of open systems interaction, but with some additions and changes. This approach generally allows for end-to-end management of channel and network resources of military radio systems in a complex electronic environment. In the article, the device of fuzzy logic, the theory of electronic suppression, neural networks, the theory of noise protection, the theory of antennas, noise-resistant coding are used. The proposed complex methodology should be used in the development of software for modules (units) for the assessment of advanced radio communications, based on open architecture interfaces version SCA 2.2, which will: use effective signal-code structures to ensure noise immunity of channels; to ensure efficient use of the radio frequency resource of programmable radio communication means; increase the speed of evaluation of communication channels; reduce the use of computing resources of radio communications with programmable architecture.

The article presents a method of designing a selected unmanned aerial platform flight scenario based on the principles of designing a reliable (Unmanned Aerial Vehicle) UAV architecture operating in an environment in which other platforms operate. The models and results presented relate to the medium-range aerial platform, subject to certification under the principles set out in aviation regulations. These platforms are subject to the certification process requirements, but their restrictions are not as restrictive as in the case of manned platforms. Issues related to modeling scenarios implemented by the platform in flight are discussed. The article describes the importance of Functional Hazard Analysis (FHA) and Fault Trees Analysis (FTA) of elements included in the hardware and software architecture of the system. The models in Unified Modeling Language (UML) used by the authors in the project are described, supporting the design of a reliable architecture of flying platforms. Examples of the transformations from user requirements modeled in the form of Use Cases to platform operation models based on State Machines and then to the final UAV operation algorithms are shown. Principles of designing system test plans and designing individual test cases to verify the system’s operation in emergencies in flight are discussed. Methods of integrating flight simulators with elements of the air platform in the form of Software-in-the-Loop (SIL) models based on selected algorithms for avoiding dangerous situations have been described. The presented results are based on a practical example of an algorithm for detecting an air collision situation of two platforms.

Many automobile security systems are provided today, but their functions are not enough to satisfy the applications for Environmental Monitoring based on Service Oriented Architecture (SOA).In this paper, we proposed and introduced new device which is an automobile information Identification device with sensors network to strengthen automobile security system function for monitoring environment. This device aims at monitoring status of automobile as well as its environment by collecting data through sensors network. In order to increase the security, we used a new designed architecture of sensors network to gather data. GPS and GPRS were also added to locate the automobile and to transmit filtered data into the monitor. A New Design approach of system was discussed on both software and hardware. One math model for showing gas and voltage value relation was established. In order to improve system reliability, various testing methods were applied in this system. The results showed that the combination of average filtering algorithm and median filtering algorithm to inhibit interference signal at variety of frequency case can effectively filter different frequency interference signal in the software system. The advantage of this system was discussed. The system has low cost, high performance, real-time and reliability characteristics. It can not only strengthen current security system functions but also can satisfy requirements of future automobile. It also has large potential market.

Full textAbstract:
The realization of the first prototype of a vehicle requires several tests of the algorithms implemented on the electronic control unit (ECU). This represents an important step for conventional vehicles, which becomes fundamental when dealing with unmanned vehicles. Since there is no human supervision, most critical tasks are handled by the control unit, which results in higher complexity for the control algorithms. In this work, a software-in-the-loop (SiL) test bench is used to validate the control algorithms of a vehicle control unit (VCU) for a driverless railway vehicle (DLRV). The VCU manages the control of the traction motors, pneumatic braking systems, and range extender, as well as control of the hybrid powertrain configuration to guarantee a high level of availability via the use of redundant systems. The SiL test bench has been developed in a Simulink real-time environment, where the vehicle model is simulated along with its fundamental subsystems. The model communicates with the VCU through a CAN bus protocol in the same way that it will operate with a real vehicle. The proposed method can be used to simulate many mission profiles for the DLRV, which may last several hours each. Moreover, this kind of test bench ensures a high time resolution, which allows one to find solutions for problems which occur with a time scale that is much smaller than the simulation time scale.

Connected Vehicles (CV) are an emerging technology with a large potential to improve traffic operations and safety. This paper develops and tests advanced CV-based multi-level conditional Transit Signal Priority (TSP). The algorithms are using the latitude/longitude (lat/lon) coordinates of CV vehicles and intersections to establish communication, share information and request priority. The TSP strategies are implemented through controllers’ built-in features and logic processor, using Econolite ASC/3 as a representative traffic signal controller. The tests were performed in VISSIM microsimulation with the ASC/3 Software-in-the-Loop (SIL) controller emulator. State Street in Salt Lake City, UT, is selected as a test-case corridor. The paper shows that the developed signal control priority (SCP) algorithms are successful in reducing delays for target vehicles in excess of 6%, without significant impacts on other traffic. The information obtained from CV vehicles can be used to further enhance control algorithms and create adaptive SCP programs.

Flexibilization of Gas Turbine Combined Cycle (GTCC) is a key for plant operations in the present as well as in the near future. The increasing of non-dispatchable sources in the energy production environment causes strong fluctuations in energy price and energy production profiles. The opportunity to enhance flexibility of traditional GTCC is consequenlty welcomed. This work focuses on integration of a Heat Pump in a GTCC devoted to cogenerative purpose with the goal to integrate energy production, assist the power plant in normal operations and enriches the transient capability of the whole compound. This approach can be developed to be retro-fitted to existing power plant. In particular, a software-in-the-loop (SiL) application is here presented to test the developed control logics governing such power plant. The power plant model is developed and runs under Siemens AMESIM environemnt, whilst the control system is developed and integrated in Matlab/Simulink environment. The two systems are intefraced and exchange information with the goal to verify reliability of the control logics before going into the real field..

Full textAbstract:
The integration of variable distributed generations (DGs) and loads in microgrids (MGs) has made the reliance on communication systems inevitable for information exchange in both control and protection architectures to enhance the overall system reliability, resiliency and sustainability. This communication backbone in turn also exposes MGs to potential malicious cyber attacks. To study these vulnerabilities and impacts of various cyber attacks, testbeds play a crucial role in managing their complexity. This research work presents a detailed study of the development of a real-time co-simulation testbed for inverter-based MGs. It consists of a OP5700 real-time simulator, which is used to emulate both the physical and cyber layer of an AC MG in real time through HYPERSIM software; and SEL-3530 Real-Time Automation Controller (RTAC) hardware configured with ACSELERATOR RTAC SEL-5033 software. A human–machine interface (HMI) is used for local/remote monitoring and control. The creation and management of HMI is carried out in ACSELERATOR Diagram Builder SEL-5035 software. Furthermore, communication protocols such as Modbus, sampled measured values (SMVs), generic object-oriented substation event (GOOSE) and distributed network protocol 3 (DNP3) on an Ethernet-based interface were established, which map the interaction among the corresponding nodes of cyber-physical layers and also synchronizes data transmission between the systems. The testbed not only provides a real-time co-simulation environment for the validation of the control and protection algorithms but also extends to the verification of various detection and mitigation algorithms. Moreover, an attack scenario is also presented to demonstrate the ability of the testbed. Finally, challenges and future research directions are recognized and discussed.

Full textAbstract:
Background: The specification of missions to be accomplished by a robot swarm has been rarely discussed in the literature: designers do not follow any standardized processes or use any tool to precisely define a mission that must be accomplished. Methods: In this paper, we introduce a fully integrated design process that starts with the specification of a mission to be accomplished and terminates with the deployment of the robots in the target environment. We introduce Swarm Mission Language (SML), a textual language that allows swarm designers to specify missions. Using model-driven engineering techniques, we define a process that automatically transforms a mission specified in SML into a configuration setup for an optimization-based design method. Upon completion, the output of the optimization-based design method is an instance of control software that is eventually deployed on real robots. Results: We demonstrate the fully integrated process we propose on three different missions. Conclusions: We aim to show that in order to create reliable, maintainable and verifiable robot swarms, swarm designers need to follow standardised automatic design processes that will facilitate the design of control software in all stages of the development.

In municipality of Ugljevik (Bosnia and Herzegovina), the coal-fired thermal power plant is located in the vicinity of the populated area. The ambient air quality monitoring within this area were not systematically performed in the previous period. This research was the first to include indicative measurement of pollutant concentration in air combined with modeling techniques for the purpose of a preliminary assessment of impact which the power plant has on air quality. Since coal, with the sulfur content of 3-6%, is used, as well as the fact that there was no flue gas desulphurization during the research period, this paper shows the results for SO2 as one of the most prominent indicators of pollution originating from the power plant. As a complement to the measurements, modeling of SO2 dispersion was carried out using ADMS5 software. The measurements indicated increased ground-level concentrations of SO2. Additionally, the modeling of SO2 dispersion with real meteorological data was carried out. The modeling confirmed high SO2 concentrations in research area. Also, it was found that the high episodic ground-level SO2 concentrations are the consequence of the terrain configuration and meteorological conditions.

The aim of this research is to develop 1-D mathematical equation that relates Normalized mean Square Error (NMSE) to depth of hydrocarbon (HC) for data processed using cubic spline interpolation in sea bed logging (SBL) application. Simulations were conducted using CST software that replicated real SBL environment to generate synthetic data. Frequency of 0.25Hz was used and sediment thicknesses were varied from 1000m to 3000m and incremented at every 250m. Data collected were interpolated using cubic spline and NMSE were calculated between original and interpolated data. Mathematical equation that relates NMSE (y) and depth of hydrocarbon (x) was constructed in terms of linear, exponential, logarithm and polynomial degree 2, 3, 4 and R2 were calculated for each equation. Mathematical equation using exponential function was adopted because it has reasonably high R2 and can be inversed easily. Average percentage error was calculated between calculated and measured data to achieve 5 % or lower values. If achievable, this model was accepted as forward mathematical model for SBL. Otherwise, the coefficients were adjusted and the processes repeated until minimum average error was achieved.

This paper proposes a novel adaptive controller based on digital twin (DT) by integrating software-in-loop (SIL) and hardware-in-loop (HIL). This work aims to reduce the difference between the SIL controller and its physical controller counterpart using the DT concept. To highlight the applicability of the suggested methodology, the regulation control of a horizontal variable speed wind turbine (WT) is considered for the design and assessment purposes. In the presented digital twin framework, the active disturbance rejection controller (ADRC) is implemented for the pitch angle control of the WT plant in both SIL and HIL environments. The design of the ADRC controllers in the DT framework is accomplished by adopting deep deterministic policy gradient (DDPG) in two stages: ( i ) by employing a fitness evaluation of wind speed error, the internal coefficients of HIL controller are adjusted based on DDPG for the regulation of WT plant, and ( ii ) the difference between the rotor speed waveforms in HIL and SIL are reduced by DDPG to obtain a similar output behavior of the system in these environments. Some examinations based on DT are conducted to validate the effectiveness, high dynamic performance, robustness and adaptability of the suggested method in comparison to the prevalent state-of-the-art techniques. The suggested controller is seen to be significantly more efficient especially in the compensation of high aerodynamic variations, unknown uncertainties and also mechanical stresses on the plant drive train.

Abstract In refineries, due to the environmental pollutions, sulfur content in petroleum need be reduced. The incineration process is used for sulfur recovery system which is not friendly process to the environment and needs high temperature. This actual process exhaust high amount of SO2 from the incinerator stack to the environment. The Claus process is the best method to recover sulfur from acid gases that contain hydrogen sulfide. The particular reaction for sulfur removal from sour gas is hydrogen sulfide (H2S) sulfur dioxide (SO2) reformation (2H2S+O2=S2+2H2O). The aim of this study is to get a simulation that is suitable for the characterization of sulfur recovery units. The experimental design for this study was collected from a petroleum refinery located in Iran. This experimental relation supports us to gather with definite consistency that is normally not available online for such process. Aspen HYSYS v8.8 software was used to simulate the Claus process by reactors and component splitters. The result shows the complete conversion of sour gas to product. The simulation protects the environmental impact by SO2 emission. This behavior can be reproduced by this HYSYS design very well. It was found that the BURNAIR feed composition and molar flow is the only factors which can affect the hydrogen sulfide conversion. The sulfur mole fraction increased only in the range of 0.94 to 0.98 by increasing N2 from 0.7 to 0.9.

In this study, the prediction of the concentration of gaseous pollutants around Ughelli West gas flow station in Delta State of Nigeria was carried out using Geostatistical technique in GIS environment. Since air pollutants negatively affect quality of air, lives and the environment, there is therefore the need to frequently monitor air quality, have thorough understanding of the pollutants’ concentration and their spatial distribution in an environment. The gaseous pollutants data of volatile organic compounds (VOCs), methane (CH4), nitrogen dioxide (NO2), sulphur dioxide (SO2) and ozone (O3), were obtained using Multi-parameter gas monitor while that of fine particulate matter (PM2.5) was obtained with SPM meter for a period of three months. Thermo Anemometer was used to obtain the values of wind speed, ambient temperature, atmospheric pressure and relative humidity. Artificial Neural Network designer software (Pythia) was used to validate the acquired field data; predict the concentration of the gaseous pollutants at selected distances from the flow station. The geospatial coordinates of the flow station were obtained using Global Navigation Satellite System (GNSS) receivers; the geospatial modelling and analysis were performed with ArcGIS software and ordinary kriging method of Geostatistical techniques. The results of the maximum concentration for the gaseous pollutants in the study area were 28.17 µg/m3, 19.44 µg/m3, 0.37 µg/m3, 49.81 µg/m3, 0.061 µg/m3 and 0.047µg/m3 for VOCs, CH4, NO2, PM2.5, O3 and SO2 respectively. The root mean square error for the concentration of the gaseous pollutants, ozone and sulphur (IV) oxide in the study area were 0.01618 and 0.008417 indicating a good interpolation model, while their root mean square standard errors, which show the reliability of the predicted values, were 0.70513551 and 0.8459251 respectively. These results conform with the report of other researchers that a better kriging method yields a smaller root mean square and a standard root mean square closer to one. The developed prediction maps for the gaseous pollutants in this study revealed that the study area will experience lower concentration of gaseous pollutants at a distance of 400 m and above.

Full textAbstract:
This paper presents the process of measuring the level of quality control process to ensure the quality of delivered software package during the development cycle. The success of the project requires three pre-requisites and they constrain one another. Quality is the most important factor for successful project completion. In other words, quality should not be sacrificed for the sake of meeting cost budget or delivering within schedule. Also, cost caused by any quality issues such as defect resolution increases exponentially once the product is out of the door. Having said that, we also have to consider the schedule side of constraints for the successful project. In other words, we have no time to do a quality job and we have to compete with other competitors to ship the product to the market earlier than them. So, the quality measurement and management concept is introduced to meet the agile software development environment in conjunction with performance strategies to execute within organization. Obviously, there are many key performance indexes derivable from the actual data associated with quality control activities and it is desirable to create a quality process to integrally represent overall level of quality control activities performed while developing the software deliverables. With the quality process, it is possible to evaluate whether enough quality control activities are performed for the project officially and secure the quality of the software deliverables before it is delivered to the customers.

For the protection of Jinan springs, based on the monitoring data of groundwater quality during dry seasons in 2013, the chemical characteristics evolution of karst water was analyzed by RockWare Aq·QA software, combined with hydrogeological conditions in jinan spring area. According to the groundwater quality standard, the present situation of karst water was evaluated. On the basis of the F value of evaluation, the groundwater quality zone is partitioned by ArcGIS software. The results show that: (1) the groundwater chemical types complicated from the single type (HCO3–Ca and HCO3–Ca·Mg) in 1950s to some new types (HCO3·SO4-Ca,Cl·HCO3-Ca and Cl·SO4-Ca); (2) karst water chemical environment has changed, so that karst erosion rate accelerated; (3) the groundwater quality partition shows most of this area is good water, only part of this area is IV,V type water (poor water). Research suggests Jinan karst water quality has been deteriorating.

More and more people across the world seek a university education. Therefore, universities offer full or partial distance undergraduate and postgraduate degrees to meet that demand. Distance education has become more widespread with advances in the Internet and computer technologies and online learning and teaching software (e.g., Learning Management Systems). The spread of the Coronavirus disease (COVID-19), which broke out in early 2020, has also played a significant role in the increased popularity of distance education. Therefore, investigating and reporting upon university students’ self-leadership (SL) behaviors, self-directed learning (SDL) skills, and online learning (OL) attitudes in such learning environments is both timely and critical. This empirical study used a relational survey model to investigate SL, SDL, and OL among university students. The sample consisted of 835 students in Turkey. Data were collected using the “Self-Directed Learning Scale (SDLS),” “Revised Self-Leadership Questionnaire (RSLQ),” and “Online Learning Attitude Scale (OLAS).” Data were analyzed using descriptive statistics, Pearson coefficient, Confirmatory Factor Analysis (CFA), and Structural Equation Modeling (SEM). SL was moderately and positively correlated with SDL and OL. SDL was moderately and positively correlated with OL. SDL played a fully mediating role in the relationship between SL and OL. SL predicted OL in both the indirect and total effect model. This study addressed university students’ perceptions and tested a model to provide empirical evidence for the relationships and predictions of SL, SDL, and OL. Therefore, it is believed that the results will help advance the constructs of SDL, SL, and OL paradigms.

Harmonious development of 3Es (economy-energy-environment) system is the key to realize regional sustainable development. The structure and components of 3Es system are analyzed. Based on the analysis of causality diagram, GDP and industrial structure are selected as the target parameters of economy subsystem, energy consumption intensity is selected as the target parameter of energy subsystem, and the emissions of COD, ammonia nitrogen, SO2, andNOXand CO2emission intensity are selected as the target parameters of environment system. Fixed assets investment of three industries, total energy consumption, and investment in environmental pollution control are selected as the decision variables. By regarding the parameters of 3Es system optimization as fuzzy numbers, a fuzzy chance-constrained goal programming (FCCGP) model is constructed, and a hybrid intelligent algorithm including fuzzy simulation and genetic algorithm is proposed for solving it. The results of empirical analysis on Shandong province of China show that the FCCGP model can reflect the inherent relationship and evolution law of 3Es system and provide the effective decision-making support for 3Es system optimization.

Full textAbstract:
In the processes of an oil refinery, considerable emissions of atmospheric pollutants are
generated that produces hazard to mans health and the environment. In this study, the
obtained results of the characterization of the gaseous emissions by chimneys of the furnaces
and boilers of the refinery are presented. The sampling and analysis of SO2, NOX, CO,
total suspended particles, and flow measurements were carried out. The aromatic
hydrocarbons were determined by UV Spectroscopy. The model of dispersion of pollutants
emitted by chimneys was executed using the software for the calculation of the gas
concentration from continuous industrial sources following the methodology approved in
the Cuban standards, according to the Berliand Model. We conclude that the combustion
processes of the Refinery reflect a fault, given the particles emissions. The emissions of
the furnaces and boilers exert negative impact or pressure on the atmospheric environment
in the area.

O sistema fotovoltaico é um método de geração de energia completamente sustentável, a utilização envolve uma tecnologia avançada em que o painel absorve a irradiação do Sol por meio do silício. Grande parte da instalação dos painéis são destinados a cobertura do imóvel ou em último caso sendo solucionado com uma usina de solo. A quantidade de painéis é estabelecida conforme o consumo médio da empresa, medida essa fornecida pela concessionaria de energia. A partir das informações pertinentes a elaboração do projeto, esse artigo tem o propósito de desenvolver um estudo de caso referente a viabilidade do sistema fotovoltaico, onde apresenta etapas de dimensionamento em um software com a aplicação dos painéis na cobertura. A finalidade do procedimento é destacar locais de sombreamento e determinar o posicionamento dos painéis.
