Forecasting of Significant Wave Height Based on Gated Recurrent Unit Network in the Taiwan Strait and Its Adjacent Waters
Authors: Wang Jichao , Wang Yue , Yang Jungang
Published: January 2021

Significant wave height (SWH) forecasting is a key process for offshore and costal engineering. However, accurate prediction of the SWH is quite challenging due to the randomness and fluctuation features of waves. This paper employs a novel deep learning method, the gated recurrent unit network (GRU), to forecast SWH with lead times of 3, 6, 12 and 24 h. The data sets used in this study include the wind speed of the past 3 h and the current SWH as inputs, which were obtained from six buoy stations in the Taiwan Strait and its adjacent waters. The GRU results are compared with those of back propagation neural network (BP), extreme learning machine (ELM), support vector machine (SVM), and random forest (RF). Although the error indices of the six stations are different, the general performance of GRU is satisfactory, with a faster forecasting speed, smaller volatility and better adaptability. Using buoy station 46714D as an example, the root mean square error (RMSE) predicted by GRU reaches 0.234, 0.299, 0.371, and 0.479 with lead times of 3, 6, 12, and 24 h, respectively.
Relative Performance of 1-D Versus 3-D Hydrodynamic, Water-Quality Models for Predicting Water Temperature and Oxygen in a Shallow, Eutrophic, Managed Reservoir
Authors: Man Xiamei , Lei Chengwang , Carey Cayelan C. , Little John C.
Published: January 2021

Many researchers use one-dimensional (1-D) and three-dimensional (3-D) coupled hydrodynamic and water-quality models to simulate water quality dynamics, but direct comparison of their relative performance is rare. Such comparisons may quantify their relative advantages, which can inform best practices. In this study, we compare two 1-year simulations in a shallow, eutrophic, managed reservoir using a community-developed 1-D model and a 3-D model coupled with the same water-quality model library based on multiple evaluation criteria. In addition, a verified bubble plume model is coupled with the 1-D and 3-D models to simulate the water temperature in four epilimnion mixing periods to further quantify the relative performance of the 1-D and 3-D models. Based on the present investigation, adopting a 1-D water-quality model to calibrate a 3-D model is time-efficient and can produce reasonable results; 3-D models are recommended for simulating thermal stratification and management interventions, whereas 1-D models may be more appropriate for simpler model setups, especially if field data needed for 3-D modeling are lacking.

Published: January 2021

This work informs on the green synthesis of a novel adsorbent and its adsorption capacity. The adsorbent was synthesized by the combination of iron nanoparticles and cellulose nanofibers (FeNPs/NFCs). Cellulose nanofibers (NFCs) were obtained from Moringa (Moringa oleifera Lam.) by a pulping Kraft process, acid hydrolysis, and ultrasonic methods. The adsorption method has advantages such as high heavy metal removal in water treatment. Therefore, cadmium (Cd) and lead (Pb) adsorption with FeNP/NFC from aqueous solutions in batch systems was investigated. The kinetic, isotherm, and thermodynamic parameters, as well as the adsorption capacities of FeNP/NFC in each system at different temperatures, were evaluated. The adsorption kinetic data were fitted to mathematical models, so the pseudo-second-order kinetic model described both Cd and Pb. The kinetic rate constant (K2), was higher for Cd than for Pb, indicating that the metal adsorption was very fast. The adsorption isotherm data were best described by the Langmuir–Freundlich model for Pb multilayer adsorption. The Langmuir model described Cd monolayer sorption. However, experimental maximum adsorption capacities (qe exp) for Cd (>12 mg/g) were lower than those for Pb (>80 mg/g). In conclusion, iron nanoparticles on the FeNP/NFC composite improved Cd and Pb selectivity during adsorption processes, indicating the process’ spontaneous and exothermic nature.

Authors: Geraldini Serena , Bruschi Antonello , Bellotti Giorgio , Taramelli Andrea
Published: January 2021

According to the global growth of the “Blue economy”, coastal zones are under pressure from both land and marine side economic activities. The fragmentation of sectorial interests and legislation along the coasts has led to the need for bridging knowledge (data/information and methods/tools) and governance (decision-makers at every level) in order to ensure sustainable economic development and social and ecosystem resilience. This poses the need for an interaction process that associates user needs to the European and national legislative framework to create a policy-oriented demand of Copernicus Earth Observation services in coastal areas. Such goals need a strong and effective system to monitor compliance and to assess the progress of the legislation. This study aims at identifying potential gaps in the current Copernicus product offer for the monitoring of the coastal sector through the elicitation of stakeholder requirements. The methodology is applied to the Italian landscape of users, but it is scalable at European level. The results provide a clear overview of the coastal user requirements, highlighting the common need of integrated information for the management, and represents the basis for defining the coastal services.
Magnesium as Environmental Tracer for Karst Spring Baseflow/Overflow Assessment—A Case Study of the Pertuso Karst Spring (Latium Region, Italy)
Authors: De Filippi Francesco , Iacurto Silvia , Grelle Gerardo , Sappa Giuseppe
Published: January 2021

Following a previous research carried out on the same site, this paper presents the update of the Mg2+ based method for the estimation of Pertuso Spring discharge, located in Central Italy. New collected data confirmed the validity of the proposed model and the conservative behaviour of Mg2+ for groundwater related to the Pertuso Spring aquifer. Further analysis allowed to obtain a local linear relationship between magnesium concentration and total spring discharge (including exploitation rate), regardless of the mixing model proposed with the Aniene River. As regards two samples which fall out of the linear relationship and could have been detected as “outliers”, more in-depth data processing and sensitivity analyses revealed that the lowering in magnesium, at equal discharges, is determined by the appearance of the quick-flow component, less mineralized and related to storm events. Results showed that under specific conditions, related to the absence or presence of previous intense rainfall events, Mg2+ could be effectively a useful tracer for separating spring conduit flow (overflow) from diffuse flow (baseflow) within the karst aquifer.

Authors: Alifujiang Yilinuer , Abuduwaili Jilili , Ge Yongxiao
Published: January 2021

This study investigated the temporal patterns of annual and seasonal river runoff data at 13 hydrological stations in the Lake Issyk-Kul basin, Central Asia. The temporal trends were analyzed using the innovative trend analysis (ITA) method with significance testing. The ITA method results were compared with the Mann-Kendall (MK) trend test at a 95% confidence level. The comparison results revealed that the ITA method could effectively identify the trends detected by the MK trend test. Specifically, the MK test found that the time series percentage decreased from 46.15% in the north to 25.64% in the south, while the ITA method revealed a similar rate of decrease, from 39.2% to 29.4%. According to the temporal distribution of the MK test, significantly increasing (decreasing) trends were observed in 5 (0), 6 (2), 4 (3), 8 (0), and 8 (1) time series in annual, spring, summer, autumn, and winter river runoff data. At the same time, the ITA method detected significant trends in 7 (1), 9 (3), 6(3), 9 (3), and 8 (2) time series in the study area. As for the ITA method, the “peak” values of 24 time series (26.97%) exhibited increasing patterns, 25 time series (28.09%) displayed increasing patterns for “low” values, and 40 time series (44.94%) showed increasing patterns for “medium” values. According to the “low”, “medium”, and “peak” values, five time series (33.33%), seven time series (46.67%), and three time series (20%) manifested decreasing trends, respectively. These results detailed the patterns of annual and seasonal river runoff data series by evaluating “low”, “medium”, and “peak” values.
Numerical Simulations of Non-Point Source Pollution in a Small Urban Catchment: Identification of Pollution Risk Areas and Effectiveness of Source-Control Measures
Authors: Pan Ye , Guo Jiaxun , Yang Long , Yuan Qiqi , Ren Zhihui , Wang Lachun
Published: January 2021

Urban non-point source pollution is becoming a serious issue under the context of rapid urbanization and its impacts on surface hydrologic processes. The identification of non-point source risk areas and the effectiveness of source-control measures provides important first steps to improve the degrading aquatic environment but is challenged by the complex dynamics and variabilities of surface pollutants in urban environments. In this study, we investigate the spatial and temporal variabilities of non-point source pollution in a small urban catchment based on numerical simulations and in-situ samplings. Our results show that residential, industrial, and commercial land contribute to the most pollutant loadings and are the main constituents of the pollution risk area. Rainfall duration and intensity are the main factors in determining the temporal variations of urban non-point source pollution. There is no correlation between early drought days and pollution load. Numerical simulations show that it is more effective to increase urban vegetation coverage than to enhance road cleaning for effective non-surface pollution control. For enhanced road cleaning, it is more effective to improve the frequency of road cleaning than its efficiency. Our results provide important guidance for effective controls of non-point source pollution as well as the establishment of long-term surface pollutant monitoring network in complex urban environments.

Authors: Zhou Su , Jin Jie , Wei Yuehua
Published: January 2021

The purpose of this research is to develop a representative driving cycle for fuel cell logistics vehicles running on the roads of Guangdong Province for subsequent energy management research and control system optimization. Firstly, we collected and preliminarily screened the 42-day driving data of a logistics vehicle through the remote monitoring platform, and determined the vehicle characteristic signal vector for analysis. Secondly, the principal component analysis method is used to reduce the dimensionality of these characteristic parameters, avoiding the linear correlation between them and increase the comprehensiveness of the upcoming clustering. Next, the dimensionality-reduced data are fed to a clustering machine. K-means clustering method is used to gather the segmented road sections into highway, urban road, national highway and others. Finally, several segments are chosen in accordance to the occurrence possibility of the four types of road conditions, minimizing the deviation with the original data. By joining the segments and using a moving average filtering window, a typical driving cycle for this fuel cell logistics vehicle on a fixed route is constructed. Some statistical methods are done to validate the driving cycle.The effectiveness analysis shows the driving cycle we constructed has a high degree of overlap with the original data. This positive result provides a solid foundation for our follow-up research, and we can also apply this method to develop other urban driving cycles of fuel cell logistics vehicle.

Acoustic tweezers have great application prospects because they allow noncontact and noninvasive manipulation of microparticles in a wide range of media. However, the nontransparency and heterogeneity of media in practical applications complicate particle trapping and manipulation. In this study, we designed a 1.04 MHz 256-element 2D matrix array for 3D acoustic tweezers to guide and monitor the entire process using real-time 3D ultrasonic images, thereby enabling acoustic manipulation in nontransparent media. Furthermore, we successfully performed dynamic 3D manipulations on multiple microparticles using multifoci and vortex traps. We achieved 3D particle manipulation in heterogeneous media (through resin baffle and

macaque and human skulls) by introducing a method based on the time reversal principle to correct the phase and amplitude distortions of the acoustic waves. Our results suggest cutting-edge applications of acoustic tweezers such as acoustical drug delivery, controlled micromachine transfer, and precise treatment.

Hierachical model-algorithmic complex of combined planning and proactive control regarding the example of railway train group coordination
Authors:   St. Petersburg Federal Research Center of the Russian Academy of Sciences (SPC RAS), Gnidenko A.S.
Published: January 2021

Aim. At present there are quite a few systems that automate the control of a train or group of trains in order to reduce manual control and create an optimal schedule within the railway network. However, those systems are mostly based on rules of thumb and lack universality, so they have a fairly narrow scope of application. The original software and algorithmic complex considered in this article allows to solve this problem of multi-level planning, optimizes the capacity of the railway network, and minimizes violations of the due arrival times. Materials and methods. An original multi-model software and algorithmic complex, divided into several layers is used to solve the described problem of multi-level planning. At the lower level of the hierarchy, the movement of an individual train is planned, the next level is devoted to regarding the processes of passing a particular section of the network to technological works in terms of network planning, and at the upper level evaluation and optimization of integrated quality indicators for a whole group of trains, as well as evaluating and adding stability reserves to the built plan take place. Results. An original method and a software-algorithmic complex based on it were developed. This system solves the problem of planning and coordinating a group of trains within a single railway network in order to optimize its capacity and minimize violations of arrival deadlines. Along with this, the developed complex solves the problem of proactive real-time train control, and can be used as a decision support system. Conslusions. The proposed methodic, using fundamental approaches, can signifi cantly reduce the complexity of the original multidimensional computational problem by solving it by a hierarchy of models and reducing the original task to a network planning problem. The developed softwarealgorithmic complex solves a wide range of tasks in terms of train group movement planning and coordination, and has a high versatility. Therefore, the chosen approach has good prospects, but it requires further testing and application for real transport systems to prove its effi ciency.

Published: January 2021

A large number of toll road projects with a barrier toll collection system are currently being implemented in Russia. Therefore, it seems relevant to study the toll plaza as an element of the transport infrastructure. Insuffi cient attention to the issues of assessing current and predicted intensity on TPscan cause regular traffi c congestions on toll roads. The goal of this study is to build a simulation model that allows to evaluate the capacity of the toll collection point during the operation of the toll road at different traffi c fl ow rates, taking into account the ratio of different types of vehicles and user behavior errors. Visual observation materials are used, the research method is discrete-event simulation of PVP using AnyLogic software, processing of the results is performed in the statistical package R. The toll point (TP) the Western High-Speed Diameter toll road in St. Petersburg, Russia was considered as a case for the study.As a result was build simulation model of TP was developed, taking into account the traffi c specifi cs and user behavior errors. Conducted experiments established the peak traffi c intensities, when traffi c congestion begins to form at the TP, with different ratios of electronic toll collection usage. During the analysis, few cases of service time distribution were considered — from low to high traffi c intensities. Main conclusions of the study: -for the low intensity case, the results of the analysis showed the splitting of the total distribution of the service time into two distributions for different operating modes of toll lanes, — for high intensity, the infl uence of user behavior on service time distribution was revealed, — for each case, the parameters of the gamma laws of service time distribution were determined, — in case of insuffi cient throughput capacity, the TP stops working effi ciently, and service time distribution increases, regardless of the type of payment. Estimated peak hours of TP operation, when there is a potential for congestion at the TP were defi ned. Possible ways of further increase thetoll collection system throughput capacity for the TP were indicated.

Classifying literary genres
Authors: Omar Abdulfattah
Published: January 2021

Classifying literary genres has always been methodologically confined to philological methods and what is commonly known as Vector Space Clustering (VSC). The problem has been exasperated with the widening gap between computational theory and traditional analysis of literary texts. Towards finding a solution to this problem, the current study utilizes a synergetic approach that brings together two established methods. First, a computational model of genre classification is drawn upon for identifying concept-based, rather than word-bound, topics, where the representation of texts is secured via the ‘bag of concepts’ (BOC) model as well as the sense-restricted knowledge and meaningful links holding between and among concepts; relatedly, the two model strands of explicit semantic analysis (ESA) and ConceptNet have enacted text classification. Second, a contextual lexical semantic approach (CRUSE, 1986, 2000) is employed so that the contextual variability of word meanings and concepts can be tackled within the confines of the target literary genres classified. The findings of present study have shown that the current composite approach of computational and semantic models has resulted in improved performance in classifying literary genres, especially with respect to delineating the links between each cluster’s document-members and generalizing about their unifying genre. Further implications have emerged from the present study, namely, the benefits reserved for digital libraries and the process of archiving, where literary-text classification has proven problematic to both users and readers in many cases.
El concepto de fluidez digital

Published: January 2021

La rápida evolución de las tecnologías digitales han desafiado la pertinencia conceptual de algunos términos, como la alfabetización digital y la fluidez digital, usados en la literatura científica para referirse a ciertas capacidades o habilidades que deben poseer los usuarios para vivir en un mundo digitalizado. Sin embargo, las diferentes aproximaciones conceptuales propuestas por los investigadores en los últimos años han provocado cierta confusión y un uso indistinto de éstas. Por lo tanto, el objetivo general del presente estudio es identificar las diferentes y más recientes aproximaciones conceptuales del término fluidez digital, además de conocer algunos aspectos del perfil de los autores y las características relevantes de los estudios. También, se intenta evidenciar las diferencias conceptuales entre el término fluidez digital y alfabetización digital, específicamente en relación con las palabras clave que constituyen dichas definiciones. El método empleado es una revisión sistemática de literatura, que comprende artículos científicos y ponencias publicadas entre el 2010 y 2020, escritas en idioma español o inglés, indexados en Scopus, Web of Science, EBSCO y ERIC. Los hallazgos muestran que el concepto de fluidez digital va más allá de los aspectos procedimentales relacionados con la tecnología, que describe el concepto de alfabetización digital, ya que los autores indican que la fluidez digital comprende otras capacidades como el pensamiento crítico, la resolución de problemas y la creatividad en el uso de la tecnología.

The Examination Impact of Speculation and Profit Sharing to the Mudaraba Deposits in Indonesia Islamic Banks
Authors: Ruhadi Ruhadi , Setiawan Setiawan
Published: January 2021

This study aims to identify the motives of customers in investing their funds in Islamic banks in Indonesia. In general, there are two motives, speculation and investment, and these two motives want to be identified in this study. As is known from sharia business principles that speculation is prohibited while investment is a motive that is permissible and even highly recommended, so it is expected to have an impact on more productive activities and can provide maximum benefits at the opening of broader employment opportunities and increased welfare people. The data used in this study are financial reports from Islamic banks collected from OJK statistics, for the period 2013 to 2017. The analytical tool used in this study is multiple regression which will relate the dependent variable of mudaraba deposits as a representation of savings in Islamic banks with two independent variables consisting of stock prices to identify stock returns as a representation of the motive of speculation as well as profit sharing or ratio which is a representation of investment motives. The results showed that stock returns simultaneously did not influence the changes in mudaraba deposits. Nevertheless the results of the partial statistical analysis indicate that the RS has a negative and significant influence on mudaraba savings. The next finding is that profit and loss sharing has a positive and statistically significant simultaneous effect on mudaraba savings in Islamic banks.
