Adopting Scenario-Based approach to solve optimal reactive power Dispatch problem with integration of wind and solar energy using improved Marine predator algorithm

The penetration of renewable energy resources into electric power networks has been increased considerably to reduce the dependence of conventional energy resources, reducing the generation cost and greenhouse emissions. The wind and photovoltaic (PV) based systems are the most applied technologies in electrical systems compared to other technologies of renewable energy resources. However, there are some complications and challenges to incorporating these resources due to their stochastic nature, intermittency, and variability of output powers. Therefore, solving the optimal reactive power dispatch (ORPD) problem with considering the uncertainties of renewable energy resources is a challenging task. Application of the Marine Predators Algorithm (MPA) for solving complex multimodal and non-linear problems such as ORPD under system uncertainties may cause entrapment into local optima and suffer from stagnation. The aim of this paper is to solve the ORPD problem under deterministic and probabilistic states of the system using an improved marine predator algorithm (IMPA). The IMPA is based on enhancing the exploitation phase of the conventional MPA. The proposed enhancement is based on updating the locations of the populations in spiral orientation around the sorted populations in the first iteration process, while in the final stage, the locations of the populations are updated their locations in adaptive steps closed to the best population only. The scenario-based approach is utilized for uncertainties representation where a set of scenarios are generated with the combination of uncertainties the load demands and power of the renewable resources. The proposed algorithm is validated and tested on the IEEE 30-bus system as well as the captured results are compared with those outcomes from the state-of-the-art algorithms. A computational study shows the superiority of the proposed algorithm over the other reported algorithms

The Psychometric Properties of the Obsessive Compulsive Drug Use Scale (OCDUS) Among Iranian Methamphetamine Abusers

Background and Aim:Drug craving as a multidimensional subjective experience recently is accepted as a hallmark for addiction. The Obsessive Compulsive Drug Use Scale (OCDUS), measures the overall craving level within a period from a multidimensional perspective. This study aimed to investigate the psychometric properties of the OCDUSamong Iranian methamphetamine abusers. Materials and Methods:OCDUS was translated from English into Farsi by language experts. The questionnaire was then used for evaluation of craving among 50 male methamphetamine abusers. Then, OCDUS questionnaire' scores was subjected to exploratory principal components factor analysis. To assess construct validity of OCDUS, the model was evaluated using confirmatory factor analysis. Internal consistency was examined by calculating Cronbach’s alpha. Results:Exploratory factor analysis identified 2-dimensional components that included, "Desire consumption and mental employment with materials", "The Impact of drug desire and Thoughts on Consumer Work and Life". Finally, the Persian version of OCDUS was verified with 10 items and two factors with high eigenvalues 76.5% of the total variance. Given the relative fit of the confirmatory factor model, the construct validity of the OCDUS was verified. Conclusion:The Farsi-translated version of OCDUS questionnaires had good psychometric properties. The questionnaire could be considered as a valid and reliable instrument for the assessment of drug craving level in Iranian methamphetamine abusers

The Psychological Impact of the COVID-19 Outbreak on Pregnancy and Mother-infant Prenatal Bonding

This study aimed to assess the impact of the COVID-19 stress and anxiety on prenatal attachment during the second trimester of gestation. Pregnancy is an important stage for mothers-to-be in creating representations of themselves as a mother , with the developing attachment relationship to the unborn child considered as a milestone in the future parent\u27s developmental trajectory. The outbreak of the COVID-19 pandemic and the national health measures installed can hence have consequences on these representations and on prenatal attachment. Our sample consisted of 95 mothers that were recruited from a prenatal ultrasound screening center. Results suggested that the COVID-19 pandemic significantly affected prenatal attachment (PAI) with significant correlations between PAI total score and age, anxiety (DASS) and stress (IES-R). When entered in one model looking for predictors of PAI total score, age and COVID-19 stress were the only variables found to significantly predict prenatal attachment. We argue for a cultural component in explaining these results, hypothesizing that stress could trigger defensive strategies, leading to more investment in the attachment relationship, potentially playing the role of a protective factor

The Psychometric Properties of the Desires for Drug Questionnaire (DDQ) among Iranians Methamphetamine Abusers

Introduction: Drug-craving as a multidimensional subjective experience recently has beenaccepted as an addiction hallmark. Desire for Drug Questionnaire or DDQ is a well-knownquestionnaire for measurement of drug craving severity. This study aimed to investigate thepsychometric properties of the DDQ among Iranian methamphetamine abusers.Method: DDQ was translated from English into Farsi by language experts. The questionnaire wasthen used for evaluation of craving among 50 male methamphetamine abusers. Then, DDQquestionnaire' scores was subjected to an exploratory principal components factor analysis. Toassess construct validity of DDQ, the model was evaluated using confirmatory factor analysis.Internal consistency was examined by calculating cronbach’s alpha.Results: Finally, the Persian version of DDQ was verified with 13 items and three factors. Threefactors with high eigenvalues were identified by (PCA) that accounted for 70.63% of the totalvariance. Given the relative fit of the confirmatory factor model, the construct validity of the DDQwas verified. Cronbach’s alpha coefficient of the total score of the questionnaire was 0.86.Conclusion: The Farsi-translated version of DDQ questionnaires had good psychometric properties.The questionnaire could be considered as a valid and reliable instrument for the assessment of drugcraving level in Iranian methamphetamine abusers

Investigating Organizational Excellence of Mahab Gas Company based on Peters and Waterman Model

The aim of this study was to evaluate organizational excellence based on Peters and Waterman model at MahabGas Company. In this model, eight variables were evaluated: prejudice to the operation, attention to customer needs, independence and employee entrepreneurship, productivity increase through staff, attention to common values, adhere to the original work, using simple structures and flexibility. This is an applied and descriptive survey study, due to the small population, all employees of MahabGas Company were chosen as statistical population. Statistical methods and different tests were used for statistical analysis using SPSS(version 22) and in a manner that is mentioned:  Kolmogorov-Smirnov test for surveying data normality, to check the validity and reliability of questionnaire, confirmatory factor analysis using LISREL8.54software and one sample Student's t-test and Friedman test were used for investigating study hypotheses. The results indicate that the observed t about eight variables of Peters and Waterman organizational excellence model in the company are not in desirable level and therefore the company based on the Peters and Waterman organizational excellence model is not a supreme organization

Gauge-invariant metric fluctuations from NKK theory of gravity: de Sitter expansion

In this paper we study gauge-invariant metric fluctuations from a Noncompact Kaluza-Klein (NKK) theory of gravity in a de Sitter expansion. We recover the well known result $\delta\rho/\rho \simeq 2\Phi$, obtained from the standard 4D semiclassical approach to inflation. The spectrum for these fluctuations should be dependent of the fifth (spatial-like) coordinate.Comment: version accepted in Phys. Lett.
