Active Learning for Robust, High-Complexity Reactive Atomistic Simulations
Authors: Lindsey Rebecca , Fried Laurence E. , Goldman Nir , Bastea Sorin
Published: July 2020

Machine learned reactive force fields based on polynomial expansions have been shown to be highly effective for describing simulations involving reactive materials. Nevertheless, the highly flexible nature of these models can give rise to a large number of candidate parameters for complicated systems. In these cases, reliable parameterization requires a well-formed training set, which can be difficult to achieve through standard iterative fitting methods. Here we present an active learning approach based on cluster analysis and Shannon information theory to enable semi-automated generation of informative training sets and robust machine learned force fields. Use of this tool is demonstrated for development of a model based on linear combinations of Chebyshev polynomials explicitly describing up to four-body interactions, for a chemically and structurally diverse system of C/O under extreme conditions. We show that this flexible training repository management approach enables development of models exhibiting excellent agreement with Kohn–Sham density functional theory (DFT) in terms of structure, dynamics, and speciation.

Published: July 2020

Background: Faculties of Medicine around the globe have implemented mindfulness-based curricula to deal with medical student’s burnout, anxiety and depression. The purpose of this qualitative study is to assess students’ perception of a mandatory mindfulness intervention and their recommendations for further curricula development and implementation.Methods:  Third-year medical students participated in a mandatory three-hour mindfulness workshop embedded in their family medicine academic week. Eleven students consented to two interviews which explored their perceptions of mindfulness and the workshop in relation to their personal and professional wellbeing as well as their views for the implementation of a longitudinal mindfulness curriculum.Results:  Student and institutional benefits and barriers relating to the curriculum were identified.  Student’s benefits included positive changes in stress, self-awareness and personally   that also translated into self-reported better patient care. Students reported lack of time, forgetting to practice and lack of knowledge about mindfulness as barriers. Institutional pride for their support of student wellness and an overfilled curriculum, were the major institutional benefits and barriers respectively, to the expansion of this curriculum. Among developing an implementing a longitudinal mindfulness curriculum, we found four key features to consider: Firstly to engage the stakeholders; secondly, to incorporate the mindfulness intervention into the curriculum with both a mandatory and elective component; thirdly, to emphasize the clinical implications of the mindfulness intervention and fourthly, to have protected time for wellness interventions.Conclusions: Introducing mindfulness into the undergraduate medical school curriculum through this workshop resulted in perceived personal, institutional and professional benefits. For faculties of medicine that want to implement a mindfulness intervention, we found four key components for implementing a mindfulness intervention in their institutions. Further research is needed to better quantify the benefits and to identify ways to manage barriers at both individual and institutional levels.

Published: July 2020

Schistosomiasis is a neglected tropical disease caused by blood flukes (trematode worms) the genus Schistosoma. Schistosomiasis is a chronic, debilitating disease that affects the populations of tropical and subtropical countries, especially children at School-age. In Sudan schistosomiasis is a major health problem adversely affecting the health of vulnerable populations. A cross-sectional study was conducted to determine the prevalence of schistosomiasis among school children in selected basic schools in Bahary Locality, Khartoum State, Sudan from December 2017 to January 2018. Urine and faecal samples were collected from 600 school-aged children and examined for the eggs of S. haematobium and S. mansoni using standard sedimentation and Kato technique, respectively. The overall of prevalence schistosomiasis 16,5% which the prevalence of S. haematobium among pupils examined was 16% and the prevalence of S. mansoni was 0.5%. Additionally, male’s reported higher prevalence (22.7%) of S. haematobium than the female’s (4.1%) also males reported higher prevalence of S. mansoni female with prevalence rate 7.7% and 2.2% for males and females respectively. According to the study participant age-groups; age group 13-15 years had the highest prevalence (22%)   of S. haematobium was recorded  and  age group 10- 12  years comes next (18.5%) followed by age group 6 -9 years (7.5%); this difference of  the age group as a factor was statistically significant (x2 = 17.9 –p value n =0.0) , but in S. mansoni age group 10-12 years had the highest (0.8%) prevalence , also  there was  statistically significant (P=0.04). This study highlights that schistosomiasis is a public health problem among children in Bahary locality. The findings of the study suggested appropriate intervention against schistosomiasis such as mass treatment, health education and control of the intermediate snail host.

Written Dārija: “māšī mə‘qūl tǝktəb-ha bi-ḥurūf al-luġa al-‘arabiyya!” It Is not Logical to Write It with the Arabic Letters!
Authors: Pennisi Rosa
Published: July 2020

This study investigates written linguistic practices emerging from public debate in Morocco. Although Darija is increasingly used in writing, especially in online platforms, most of its users still stigmatize it. In 2017 the Zakoura Foundation edited the first monolingual dictionary of Darija, a fervently debated initiative. So, this analysis aims to show the limits of such codification initiative, and factors which affect language ideology in Morocco. Therefore, a corpus of articles and readers’ comments on the Zakoura Dictionary of two Moroccan digital newspapers, Goud and Hespress, has been analyzed, quantitively and qualitatively, in order to compare the opinions about language and the language varieties in which they were expressed.

Published: July 2020

Abstrak

Penelitian untuk menganalisis hubungan antara harga minyak dunia dan harga komoditi pangan di pasar domestik masih jarang ditemukan. Dengan membuat Model Panel Data dari 34 provinsi di Indonesia pada tahun 2010-2017, penelitian ini bertujuan untuk menginvestigasi pengaruh perubahan harga minyak dunia terhadap beberapa harga komoditi pangan lokal (kedelai,import, kedelai lokal, beras lokal, dan jagung lokal). Hasil penelitian ini mengindikasikan bahwa harga minyak dunia dapat memengaruhi harga pangan lokal di Indonesia melalui tingginya biaya pengiriman pada aktivitas impor. Selain itu, harga komoditi pangan dunia juga terbukti dapat memengaruhi harga seluruh komoditi pangan lokal yang diteliti, yang mengimplikasikan bahwa harga komoditi pangan di Indonesia dipengaruhi oleh kondisi pasar internasional. Hasil penelitian ini memberikan masukan bagi pembuat kebijakan di Indonesia untuk mempertimbangkan perubahan harga minyak dunia dan harga komoditi global dalam menstabilkan harga komoditi lokal di Indonesia, terutama komoditi yang diimpor.

 

Abstract

Globally, studies examining the nexus between global crude oil prices and food commodity prices in domestic markets are scant. Employing a panel data model of 34 provinces in Indonesia from 2010 - 2017, this study investigates the impact of global crude oil’s price change on some local food commodity prices (imported soybean, local soybean, local rice, and local maize). Previous studies found that local food commodity prices in some countries were not affected by global crude oil prices; however, this study, by controlling other factors which could affect local commodity prices, finds different results. This study’s findings indicate that global crude oil prices could affect Indonesia’s local commodity prices due to higher shipping costs in import activity. In addition, global commodity prices are also proved to affect all commodities examined in this study, which implies that local food commodity prices in Indonesia are influenced by the international market. This study provides input to policymakers in Indonesia to consider the movement of global crude oil prices and global commodity prices in stabilizing local food commodity prices in Indonesia, especially the imported commodities.

Traits for depression related to agentic and external control
Authors: Castiello Santiago , Senan Salha , Msetfi Rachel M. , Murphy Robin
Published: July 2020

Depression has been linked to weakened perceptions of control. The experimental evidence derives from tasks with exposure to stable action-outcome contingencies. One assumption has been that performance represents a general cognitive bias that might manifest itself by a global performance difference. Another view is that people have specific situational perceptions of control reflecting their recent actions and the contingencies to which they are currently experiencing. In an experiment with N = 179, participants acquired one of four action-outcome sequences (Constant or Variable). We measured how learning was reflected in ratings of control and probability of responding in relation to mood. In three experimental treatments, the overall contingency across training involved an average moderate degree of control (∆P = 0.25), but differed in how control varied (Constant or one of two Variable treatments). A fourth, control treatment involved a Constant zero degree of control (∆P = 0.00). Participants rated their control before, during and after each sequence, providing measures of pre-existing bias, ratings of control in specific situations and generalised control perceptions. Specific control ratings were only influenced by the contingency experience and not pre-existing bias. Higher scores on the Beck’s depression inventory were associated with weakened association between action and context ratings. Overall, these data suggest that human agency is related to rates of responding and that mood is related to a difference in sensitivity to the ratings of and responding to the context.
Values, Social Dominance Orientation (SDO), and Pro-Environmental Beliefs: A 20-Nation Study
Authors: Vilar Roosevelt , de Carvalho Rodrigues Araujo Rafaella , Liu James H
Published: July 2020

Abstract. The predictive value of Social Dominance Orientation (SDO) and Human Values on the beliefs that (1) human activity is causing climate change, and that (2) governments of the world should act together to reduce global carbon emissions are examined in 20 countries. We also examined whether country level variables (e.g., environmental performance index - EPI) would influence such relationships. With representative samples from 20 countries (Wave 1 = 21,362; Wave 2 = 8,174), and using multilevel regressions, results showed negative effects of SDO and positive effects of the value dimensions of existence, suprapersonal, and interactive on environmental concerns. Cross-level interactions found that existence values (e.g. valuing health) were a stronger predictor of pro-environmental beliefs in countries with lower EPI scores. In countries with higher EPI scores (and people less exposed to potentially damaging consequences from climate change), suprapersonal values (e.g., valuing beauty) showed stronger relationships with environmental concerns.

A Fake Calibration Attack process for a Continuous Variable-Quantum Key Distribution system using a Beam Sampler is presented. The Fake Calibration Attack allows a calibration that balances the Standard Quantum Limit for all the optical path in the experiment (differential Standard Quantum Limit is ≈ 0.39 dB) allowing Eve to acquire ≈ 0.0671 for a particular information quadrature which establishes a Quantum Bit Error Rate ≈ 5.8%. As a final result, the balancing of the Standard Quantum Limit for both states of polarization signals allows maintaining the overall Quantum Bit Error Rate at a particular value ≈ 3%, which implies an important basis for detecting a potential spy considering the minimum Quantum Bit Error Rate.
Current state and possibilities for oversized municipal waste management in the regions of Ukraine
Authors: Safranov T. A. , Shanina T. P. , Prykhodko V. Yu.
Published: July 2020

Human life and activities generate municipal solid waste (MSW) consisting of municipal household waste (residential waste), waste from commercial organizations, waste from public institutions and organizations, waste from industrial enterprises, waste from urban maintenance and improvement. A common feature for all these types of waste is the fact that a municipality is an institution responsible for organization, management of its disposal process. Such waste is generated in everyday life, across the food network, when carrying out repair and construction works, in the municipal transport and communication systems, etc. The aim of the work is to assess the current state and possibilities of oversized municipal waste management in the regions of Ukraine. In order to achieve this aim, the study of the existing regulatory documents and existing experience in the field of oversized municipal waste management was conducted. The work is based on the analysis of the published data, as well as on the materials of our own research. The implementation of the MSW management system implies creation of a municipal center for recycling secondary raw materials based on the modular quarterly principle. A recycling station with a mandatory module for oversized waste reception and sorting should become a main structural element of the recycling center. In addition, it is proposed to create separate sites for collecting the oversized waste. This has already been implemented in some cities of Ukraine. When differentiating SMW flows, due attention is not paid to the used cars that can contingently be attributed to oversized secondary raw materials. In Ukraine the existing recycling centers do not meet modern requirements. Due to the lack of necessary experience in handling the used cars, one should turn to foreign experience and focus on the requirements of the developed countries. According to international standards, the life of a car is 10 years with its subsequent utilization in such a way that prevents it from having a negative impact on the environment. Since, as of today, 27% of cars in Ukraine are older than 30 years, so in case of their mandatory utilization, the number of such cars will be approximately 2.5 million. With such total number of used cars each region of Ukraine will need to handle about 100 thousand recyclable cars. It is hardly possible to create the recycling centers in each region, so, at the first stage, it is advisable to organize such centers, for example, in each economic region or cluster. The creation of the oversized municipal waste management system in the regions of Ukraine will make it possible to turn the waste into useful products, to reduce the level of a negative environmental impact and to obtain not only ecological, but also socio-economic effects.
IMPLEMENTING THE C.O.S.T.A MUNICIPAL CHANGE MODEL (M-C-M)
Authors: Costa King , Siganga Selina
Published: July 2020

Corruption, mismanagement and incompetence are perceived as a significant prevention to great administration in progressive local government. Many attempts have been developed by government to curb the scourge of this problem by establishment of a number of public sector organizations hinged upon precepts of the constitution, such as Chapter 9 institutions. Regardless of so many watch-dog organizations in South Africa, it is obvious that these instruments are lacking to forestall and control debasement, because of helpless administration rehearses, for example, shortcoming and "holes" in practice. Moreover, the government and public sector continually see exposition of lack of ethical leadership, ethical administration and ethical public service as a result. Apparent refusal to follow the statutory prescripts in the form of PFMA and MFMA demonstrate a plethora of unending meanders to total decay and maleficence.According to Naidoo (2010) Administration and service delivery failures by local government can generally be ascribed to :(1) Poor leadership(2) Unrealistic planning(3) Lack of proper community engagement (4) Trust deficit(5) Incompetent staff and managementIt is interesting that issues raised over a decade ago, which were already proving a predominant challenge to service delivery, are still a problem 10 years later and over 25 years of democratic rule in South Africa. In 2010, Naidoo's study collected data from households, which indicated that appointment of officials to office was inappropriate and irregular. This was further compounded by low skills levels and non-responsive employee capacity development suitable to the paradigm of local government. It is in this way contended there is progressively a requirement for moral authority and ethical leadership culture in the public service and local government. This article hence recommends the requirement for a framework that will put local government leadership and staff on a trajectory with sequential development indicators providing verification at each stage. The C.O.S.T.A. Framework is hereby proposed.

Mutational Analysis of Field Cancerization in Bladder Cancer
Authors: Strandgaard Trine , Nordentoft Iver , Lamy Philippe , Christensen Emil , Thomsen Mathilde Borg Houlberg , Jensen Jørgen Bjerggaard , Dyrskjøt Lars
Published: July 2020

BACKGROUND:

Morphologically normal tissue, adjacent to tumors, contains multiple molecular changes, the so-called field cancerization. The multifocal and recurrent nature of bladder cancer has been hypothesized to originate from this. However, further studies are required to explore the mutational composition of normal tissue adjacent to tumors.

OBJECTIVE:

To analyze field cancerization in bladder cancer patients using a non-tumor guided approach.

METHODS:

We investigated the mutational landscape of normal appearing urothelium and paired bladder tumors from four patients by applying deep-targeted sequencing.

RESULTS:

Sequencing of 509 cancer driver genes revealed the presence of 2– 13 mutations exclusively localized in normal tissue (average target read depth 634×). Furthermore, 6– 13 mutations were shared between tumor and normal samples and 8– 75 mutations were exclusively detected in tumor samples. More mutations were observed in normal samples from patients with multifocal disease compared to patients with unifocal disease. Mutations in normal samples had lower variant allele fractions (VAF) compared to tumor mutations ( p < 2.2*10–16). Furthermore, significant differences in the type of nucleotide changes between tumor, normal and shared mutations ( p = 2.2*10–5) were observed, and mutations in APOBEC context were observed primarily among tumor mutations ( p = 0.02). No differences in functional impact between normal, shared and tumor mutations were observed ( p = 0.61).

CONCLUSION:

Overall, these findings support the presence of more than one field in the bladder, and document non-tumor specific driver mutations to be present in normal appearing bladder tissue.

Published: July 2020

PURPOSE:

To systematically review the current literature and discuss the applications and limitations of radiomics and machine-learning augmented radiomics in the management of bladder cancer.

METHODS:

Pubmed ®, Scopus ®, and Web of Science ® databases were searched systematically for all full-text English-language articles assessing the impact of Artificial Intelligence OR Radiomics OR Machine Learning AND Bladder Cancer AND (staging OR grading OR prognosis) published up to January 2020.

RESULTS:

Of the 686 articles that were identified, 13 studies met the criteria for quantitative analysis. Staging, Grading and Tumor Classification, Prognosis, and Therapy Response were discussed in 7, 3, 2 and 7 studies, respectively. Data on cost of implementation were not reported. CT and MRI were the most common imaging approaches.

CONCLUSION:

Radiomics shows potential in bladder cancer detection, staging, grading, and response to therapy, thereby supporting the physician in personalizing patient management. Extension and validation of this promising technology in large multisite prospective trials is warranted to pave the way for its clinical translation.

Authors: Zhao Li , Wang Hao , Li Shan-Shan , Xin Feng , Wu Qi , Li Zheng-Ye , Ma Xian-Jun
Published: July 2020

OBJECTIVE: This study aimed to retrospectively analyze the blood protective effect of autologous platelet separation in operations for acute aortic dissection. METHODS: A total of 130 patients with acute aortic dissection were enrolled into the present study. The average age of these patients was 52.962±10.5061 years old. These patients underwent the modified aortic arch replacement with the elephant trunk technique or endovascular aortic exclusion with covered stent. Among these patients, 68 patients who underwent autologous platelet separation were assigned to the platelet separation group, while the remaining patients were assigned to the control group. All operations were performed under deep hypothermic circulatory arrest. After anesthesia, 1–2 therapeutic doses of autologous platelets were isolated from patients in the platelet separation group, and these platelets were quickly infused back to these patients after heparin was neutralized by protamine at the end of the cardiopulmonary bypass. The preoperative and postoperative indexes in these two groups were compared. RESULTS: There were no statistically significant differences in age, gender, smoking history, drinking history and hypertension history between these two groups. Compared with controls, the transfusion volume of allogeneic platelets in the perioperative period significantly decreased in the platelet separation group (1.919±1.6226 vs. 0.794±1.1789, P < #x003C;< #x200A;0.05), and the use rate of allogeneic platelets also significantly decreased (74.19% vs. 45.59%, P < #x003C;< #x200A;0.05). CONCLUSION: The intraoperative auto transfusion of platelets significantly reduced the volume of allogeneic platelet transfusion after the operation for aortic dissection, which has a significant blood protective effect.

OBJECTIVES: To compare the diagnostic efficacy of shear wave elastography (SWE) comnined with ACR TI-RADS categories for malignancy risk stratification of thyroid nodules with interminate FNA cytology. METHODS: The clinical data, sonographic features, ACR TI-RADS grading and shear wave elastography images of 193 patients of surgical pathologically proven thyroid nodules with interminate FNA cytology were retrospectively analyzed. The diagnostic efficacy of ACR TI-RADS categories, the maximum Young’s modulus (Emax) of SWE and the combination of the two were calculated respectively. RESULTS: The ROC curves were drawn using surgical pathology results as the gold standard. The ROC curves indicated that the cut-off value of ACR TI-RADS and Emax of SWE was TR5 and 41.2 kPa respectively, and the area under the ROC curve (AUC) was 0.864 (95% CI: 0.879–0.934) and 0.858 (95% CI: 0.796–0.920) respectively. The diagnostic sensitivity, specificity and accuracy of ACR TI-RADS was 81.4% (127/156), 84.8% (31/37), and 81.9% (158/193), respectively. That of SWE Emax was 80.8% (126/156), 78.4% (29/37), and 80.3% (155/193), respectively. After SWE combined with ACR TI-RADS, the sensitivity, specificity and accuracy was 94.2% (147/156), 75.7% (28/37), and 90.7% (175/193), respectively. CONCLUSIONS: ACR TI-RADS classification system and shear wave elastography had high diagnostic efficacy for thyroid nodules with interminate FNA cytology. The combination of the two could improve diagnostic sensitivity and accuracy, and could help to differentiate benign and malignant thyroid nodules with interminate FNA cytology.

Published: July 2020

Background: The Asian American, Native Hawaiian, and Pacific Islander (AANHPI) aging population is rapidly growing and the burden of Alzheimer’s disease and its related dementias (ADRD) will likely mirror this demographic growth. AANHPIs face significant barriers in obtaining timely ADRD diagnosis and services; yet little is known about ADRD in this population. Objective: The study objective is to conduct a systematic review on the published literature on ADRD among AANHPIs to identify gaps and priorities to inform future research and action plans. Methods: The systematic review was conducted following the PRISMA Protocol for Systematic Reviews. Co-author (TR), an experienced Medical Librarian, searched PubMed, EMBASE, PsycINFO, Cochrane Central of Clinical Trials, Ageline, and Web of Science for peer-reviewed articles describing ADRD among AANHPIs. The search was not limited by language or publication date. Each citation was reviewed by two trained independent reviewers. Conflicts were resolved through consensus. Results: The title/abstract and full texts of 1,447 unique articles were screened for inclusion, yielding 168 articles for analysis. Major research topics included prevalence, risk factors, comorbidities, interventions and outreach, knowledge and attitudes, caregiving, and detection tools. A limited number of studies reported on national data, on NHPI communities generally, and on efficacy of interventions targeting AANHPI communities. Conclusion: To our knowledge, this is the first systematic review on ADRD among AANHPI populations. Our review provides a first step in mapping the extant literature on ADRD among this underserved and under-researched population and will serve as a guide for future research, policy, and intervention.

The main purpose of this study is to enrich the theoretical system of data mining for social e-commerce users and provide a theoretical basis and reference for platform and business management and operation of social e-commerce. First, based on the information ecology and information dissemination perspective, this paper constructs the model of information flow in social e-commerce. Second, based on the social network analysis method, analyzes the social network of social e-commerce users; Finally, based on the integrated model of technology acceptance and use (UTAUT), the theory of perceived risk and the theory of trust, the conceptual model of influencing factors of initial information adoption by users of social e-commerce is constructed, and the key influencing factors are identified by using Delphi method and DEMATEL method. The experimental results show that the degree of centrality of the new technology application is the largest, 5.250, which is the key factor influencing the initial information adoption of social e-commerce users. User satisfaction has the largest influence on the continuous information adoption intention of social e-commerce users, with the influence factor reaching 1.223, followed by IT self-efficacy (0.948), user relationship network structure (0.771), social e-commerce platform quality (0.637), perceived usefulness (0.419) and emotional attachment intensity (0.409).

Aiming at the characteristics of time-frequency analysis of unsteady vibration signals, this paper proposes a method based on time-frequency image feature extraction, which combines non-downsampling contour wave transform and local binary mode LBP (Local Binary Pattern) to extract the features of time-frequency image faults. SVM is used for classification and recognition. Finally, the method is verified by simulation data. The results show that the classification accuracy of the method reaches 98.33%, and the extracted texture features are relatively stable. Also, the method is compared with the other 3 feature extraction methods. The results also show that the classification effect of the method is better than that of the traditional feature extraction method.
Design of data mining algorithm based on rough entropy for us stock market abnormality
Authors: Wang Guangtong , Miao Jianchun
Published: July 2020

The economic interaction between the countries of the world is gradually strengthening. Among them, the US stock market is a “barometer” of the global economy, which has a huge impact on the global economy. Therefore, it is of great significance to study the data in the US stock market, especially the data mining algorithm of abnormal data. At present, although data mining technology has achieved many research results in the financial field, it has not formed a good research system for time series data in stock market anomalies. According to the actual performance and data characteristics of the stock market anomaly, this paper uses data mining techniques to find the abnormal data in the stock market data, and uses the isolated point detection method based on density and distance to analyze the obtained abnormal data to obtain its implicit useful information. However, due to the defects of traditional data mining algorithms in dealing with stock market anomalies containing uncertain factors, that is, the errors caused by other human factors, this paper introduces the roughening entropy of the uncertainty data and applies its theory to the field of data mining, a data mining algorithm based on rough entropy in the US stock market anomaly is designed. Finally, the empirical analysis of the algorithm is carried out. The experimental results show that the data mining algorithm based on rough entropy proposed in this paper can effectively detect the abnormal fluctuation of time series in the stock market.

Dynamic combination control of phase movement at signal intersection under the automated vehicle environment
Authors: Xiao Wenbin , Zhu Shunying
Published: July 2020

With the continuous perfection of the technology of automated vehicles (AV), data exchange can be conveniently carried out between different vehicles and infrastructures, which makes it easier to collect different types of traffic parameters. Therefore, under AV environment, the vehicle status can be determined to obtain the periodic arrival rate of movements and a more efficient control strategy can be designed. The combination styles of phase movement (PM), an important factor of the signal control, will also become more complicated for intersection signal control. The current methods about the PM combination styles only considered two kinds of movement combination styles, and cannot get the extensive phase combination (PC) schemes in AV environment. This paper documents a new PM combination method by fractionalized movement compatibility relations, and uses discrete mathematics to calculate overall PC schemes. Then, a PM dynamic combination control method is proposed to optimize cyclically signal control. The analysis results of numerical tests showed that the average vehicle of the proposed method is reduced by 6.9 % and 14.5 % for 20 signal cycles, respectively, and the total throughput can be increased by 4.3% and 7.8%, respectively, compared with the dynamic timing control mode and the fixed control mode. Results show that the proposed method could significantly improve intersection control effectiveness.
Sizing and optimization of on-grid hybrid renewable energy systems considering hydroelectric energy storage

Published: July 2020

The economic development of any country is closely linked with the consumption of energy. Therefore, international policies encourage increasing penetration of renewable energy sources (RES) into the electrical grid in order to reduce CO2 emissions and cover ever-increasing demands. However, high variance of RES complicates their integration into power systems and complicates their transition from central to distributed energy sources. On the other hand, increasing the penetration of RES in electrical networks stimulates the demand for large capacity for energy storage. This paper presents a new approach to optimize the size of on-grid renewable energy systems integrated to pumped storage system using Salp Swarm Algorithm (SSA). This approach allows the examination of various energy sources and their combination to handle the optimal configuration of the hybrid system. The simulation and optimization process of the studied system have been carried out by MATLAB programming. The impact of the system under study on the grid is examined according to the power exchange values between the system and the grid. Moreover, different scenarios have been introduced for optimal operation. The simulation results indicate that these hybrid systems can reduce power exchange with the grid and ensure that the proposed system is economically and environmentally feasible. Furthermore, the results indicate the technical feasibility of seawater hydroelectric power plants in increasing the capacity of the electric grid to allow for high penetration of RES. Finally, the results showed that the best minimum value of the objective function is 3.9113 and showed that CO2 emission can be reduced about 29.65% per year compared to the conventional power plants.

Published: July 2020

Multisets are the nature extension of classical sets. Rough multisets are multisets in rough set context. This note studies rough multisets. We illustrate that Definition 9.1 in [4] is imperfect or irrational via an example. In order to improve this definition, we redefine rough multisets along with a illustrative example. Moreover, we obtain some properties of rough multisets based on new definition. Finally, we give applications of rough multisets.

Uncertain pantograph differential equations are an important class of pantograph differential equations driven by uncertain process. This paper investigates two types of stability, namely stability in mean and almost sure stability, for uncertain pantograph differential equations. In detail, the concepts of stability in mean and almost sure stability for uncertain pantograph differential equations are presented. Moreover, we reveal the sufficient conditions for uncertain pantograph differential equations being stable in mean and stable almost surely. Finally, this paper attempts to explore the relationships among stability in mean, almost sure stability as well as stability in measure.
