Future water availability in North African dams simulated by high resolution regional climate models
Year: 2016

In North Africa, the countries of Morocco, Algeria and Tunisia are already experiencing water scarcity and a strong interannual variability of precipitation. To better manage their existing water resources, several dams and reservoirs have been built on most large river catchments. The objective of this study is to provide quantitative scenarios of future changes in water availability for the 47 major dams and reservoirs catchments located in North Africa. An ensemble of regional climate models (RCM) with a spatial resolution of 12km, driven by different general circulation models (GCM) from the EuroCORDEX experiment have been considered to analyze the projected changes on temperature, precipitation and potential evapotranspiration (PET) for two scenarios (RCP4.5 and RCP8.5) and two time horizons (2040 2065 and 2065 2090) PET is estimated from RCM outputs either with the FAO PenmanMonteith (PM) equation, requiring air temperature, relative humidity, net radiation and wind, or with the Hargreave Samani (HS) equation, requiring only air temperature. The water balance is analyzed by comparing the climatic demand and supply of water, considering that for most of these catchments groundwater storage is negligible over long time periods. Results indicated a future temperature increase for all catchments between +1.8* and +4.2* depending on the emission scenario and the time period considered. Precipitation is projected to decrease between 14% to 27% mainly in winter and spring, with a strong East to West gradient. PET computed from PM or HS formulas provided very similar estimates and projections, ranging between +7% to +18% Changes in PET are mostly driven by rising temperatures and are greatest during dry summer months than for the wet winter season. Therefore the increased PET has a lower impact than declining precipitation on future water availability, which is expected to decrease by 19% to 33% on average.

Transient accretion disc like envelope in the symbiotic binary BF Cygni during its 2006 2015 optical outburst
Year: 2015

The optical light of the symbiotic binary BF Cyg during its last eruption after 2006 shows orbital variations because of an eclipse of the outbursting compact object. The first orbital minimum is deeper than the following ones. Moreover, the Balmer profiles of this system acquired additional satellite components indicating a bipolar collimated outflow at one time between the first and second orbital minima. This behaviour is interpreted in the framework of the model of a collimated stellar wind from the outbursting object. It is supposed that one extended disc like envelope covering the accretion disc of the compact object and collimating its stellar wind forms in the period between the first and second minima. The uneclipsed part of this envelope is responsible for the decrease of the depth of the orbital minimum. The calculated UBVRCIC fluxes of this uneclipsed part are in agreement with the observed residual of the depths of the first and second orbital minima. The parameters of the envelope require that it is the main emitting region of the line Ha but the Ha profile is less determined from its rotation and mostly from other mechanisms. It is concluded that the envelope is a transient nebular region and its destruction determines the increase of the depth of the orbital minimum with fading of the optical light.
Deployment of the agile risk management with Jira into complex product development ecosystem
Year: 2017

This work is a descriptive case study of deployment of the agile risk management with Jira into complex product development ecosystem. The context is a Development Team in Finland that is leading distributed product development for a small cell radio base station (RBS) The quality management requirements in the ISO 9001:2015 standard have been updated and the main impact is the deployment of the risk based thinking. The Development Team in Finland has gone through a transformation from release project driven development to continuous software development. This major change requires that development processes and development support processes are also updated. Focus is in the improvement of the risk management process, methods and tools. Rationale for risk management improvement is based on the findings in the internal quality audit and the management's intent is also taken into account. The implementation contains a new risk management process, customized issue type for Jira tool, risk management hands on training and replacement of the old spreadsheet based risk management tools. The new process replaces two earlier processes making things simpler. The unified approach covers both normal risks in the product development and product security and privacy related risks. Agile product development emphasizes the empowerment of the crossfunctional team. The results show that deployment of the agile risk management has shifted the risk management ownership to development teams instead of the release management function. The benefits of risk management for software industry and for the case study are included to motivate the use of the risk management in the daily operations.
Reading Online in Foreign Languages: A Study of Strategy Use.
Year: 2016

Scores of studies have established that when learning online, students must be equipped with different sets of strategies and skills than in a physical classroom setting (Anderson, 2003;  2015; Coiro, 2007; Leu et al. 2007; Michinov, Brunot, Le Bohec, Juhel, Delaval, 2011; Salmon, 2013) The present study, by virtue of exploring foreign language learners' online reading experience, aimed to identify the reading strategies that learners would use when engaged in online reading activities in the target foreign languages. Thirty two foreign language learners whose native language was English participated in the study. The Online Survey of Reading Strategies (OSORS) designed by Anderson (2003) was administered to investigate the following four research questions: (1) What are the strategies that language learners would or would not use when reading online in foreign languages? (2) Would foreign language learners use some of the online reading strategies more frequently than other strategies? (3) Would different levels of foreign language proficiencies influence language learners' use of the strategies? (4) What could foreign language teachers do in their instruction to help students acquire and broaden their repertoire of online reading strategies? Data analysis demonstrated the most and least frequently used strategies of the foreign language learners and uncovered a significant difference in the frequency of use among the strategies. However, there was no significant difference found between the use of online reading strategies and learners' foreign language proficiencies. Implications and suggestions for future research and practice were proposed accordingly.
Secure watermarking scheme against watermark attacks in the encrypted domain
Venue: J. Vis. Commun. Image Represent.
Year: 2015

We have proposed a robust watermarking scheme in the encrypted domain.For traditional schemes, original media could be exposed to the embedder.The robustness of watermark in the encrypted domain should be taken into account.We investigate the watermark attacks that can be performed in the encrypted domain.Our watermarking scheme would be helpful for copyright protection in the cloud. The homomorphic cryptosystems create a great opportunity for secure signal processing (SSP) Watermarking in the encrypted domain provides a promising solution to the security of watermarking. However, the robust performance of the watermarking scheme in the encrypted domain should be carefully considered. In this paper, we propose a robust watermarking scheme in the encrypted domain, which protects the original images from the third party embedders. The hybrid discrete wavelet transform (DWT) and discrete cosine transform (DCT) based method improves the robust performance of the encrypted domain watermarking scheme. The watermark extraction can be performed on both the plaintext and the encrypted domains. We also give an estimation of the expanding factor after watermark embedding in the encrypted domain. At last, we discuss the watermark attacks that are available in the encrypted domain. Taking Haar wavelet transform for example, we conduct the experiments on the visual quality and the robustness of our watermarking scheme, which demonstrate that the entire performance is satisfactory.
Journal Recommendation System Using Content Based Filtering
Year: 2019

Recommendation systems provide an approach to facilitate the user's desire. It is helpful in recommending the things from various domains. Researchers express their ideas and experience in an academic article for the research community. However, they have ample of options when they aspire to publish. At times, they end up with incorrect submission resulting in waste of time and effort of editor as well as himself. Journal selection has been a very tedious task for the novice authors. In this paper, Journal Recommendation System (JRS) is proposed, which will solve the problem of publication for many authors. Content based filtering method is used for this purpose. The dataset used is prepared by the authors and distance algorithm is used for recommendation.
Regional Scale Irrigation Scheduling using a Mathematical Model and GIS
Year: 2009

A user friendly software that contributes to the regional scale irrigation scheduling is presented. The software is based on the numerical solution of Richards equation which is integrated into the ArcGIS environment. Irrigation water needs are visualised by the production of coloured maps of the cultivated area. The software is aimed to the managers of the collective irrigation networks to assist them in the efficient distribution of water. In addition to that the software calculates the proper amount of water that must be applied to meet the crop needs. Therefore it offers the ability to the managers to provide specific irrigation advice to the farmers. A requirement of the software is that the study region must be densely sampled in order to be divided into homogeneous crop and soil texture sub regions. Spatial variability of the soil hydraulic parameters is handled by applying the scaling method to the set of point measurements contained within each sub region. This paper describes the main theoretical considerations behind this software and compares two irrigation cases: one with real and one with hypothetical data.
Sigma Models and Phase Transitions for Complete Intersections
Year: 2015

We study a one parameter family of gauged linear sigma models (GLSMs) naturally associated to a complete intersection in weighted projective space. In the positive phase of the family we recover Gromov Witten theory of the complete intersection, while in the negative phase we obtain a Landau Ginzburg type theory. Focusing on the negative phase, we develop foundational properties which allow us to state and prove a genus zero comparison theorem that generalizes the multiple log canonical correspondence and should be viewed as analogous to quantum Serre duality in the positive phase. Using this comparison result, along with the crepant transformation conjecture and quantum Serre duality, we prove a genus zero correspondence between the GLSMs which arise at the two phases, thereby generalizing the Landau Ginzburg/Calabi Yau correspondence to complete intersections.
Adhesion strength and spreading characteristics of EPS on membrane surfaces during lateral and central growth.
Venue: Colloids and surfaces. B, Biointerfaces
Year: 2013

Deposition of extracellular polymeric substances (EPS) on membrane surfaces is a precursor step for bacterial attachment. The purpose of this study was to analyze the morphological changes on a clean polysulfone ultrafilration membrane after exposure to effluent from a membrane bioreactor. The effluent was filtered to remove bacteria before exposing the membrane. The morphological characterization was performed by atomic force microscopy (AFM) The lateral (2D) and central growth characteristics (3D) of the EPS deposits were evaluated by section and topographical analyses of the height images. The contact angle of single EPS units was 9.07 0.50deg which increased to 24.41 1.00deg for large clusters (over 10 units) and decreased to 18.68 1.00deg for the multilayered clusters. The surface tension of the single EPS units was 49.34 1.70 mNm( 1) The surface tension of single layered small and large EPS clusters were 51.26 2.05 and 53.48 2.01 mNm( 1) respectively. For the multilayered clusters, the surface tension was 51.43 2.05 mNm( 1) The spreading values were negative for all deposits on the polysulfone membrane indicating that the EPS clusters did not have tendency to spread but preferred to retain their shapes.

Comparison of stochastic and machine learning methods for multi step ahead forecasting of hydrological processes
Venue: Stochastic Environmental Research and Risk Assessment
Year: 2019

Research within the field of hydrology often focuses on the statistical problem of comparing stochastic to machine learning (ML) forecasting methods. The performed comparisons are based on case studies, while a study providing large scale results on the subject is missing. Herein, we compare 11 stochastic and 9 ML methods regarding their multi step ahead forecasting properties by conducting 12 extensive computational experiments based on simulations. Each of these experiments uses 2000 time series generated by linear stationary stochastic processes. We conduct each simulation experiment twice; the first time using time series of 100 values and the second time using time series of 300 values. Additionally, we conduct a real world experiment using 405 mean annual river discharge time series of 100 values. We quantify the forecasting performance of the methods using 18 metrics. The results indicate that stochastic and ML methods may produce equally useful forecasts.
Quantitative microbial risk assessment (QMRA) of occupational exposure to SARS CoV 2 in wastewater treatment plants
Venue: Science of The Total Environment
Year: 2020

The current global Severe Acute Respiratory Syndrome Coronavirus 2 (SARS CoV 2) epidemic has heightened calls for studies to evaluate respiratory exposure for wastewater treatment workers. In this global first study, we assess occupational health risks to wastewater treatment plant (WWTP) operators from inhalation of aerosolized SARS CoV 2 using a Quantitative Microbiological Risk Assessment (QMRA) framework. The following considerations were used to develop the QMRA and assess the illness risks to workers: a) the proportion of the population who are infected and thus responsible for shedding SARS CoV 2 into raw wastewater; b) the concentration of SARS CoV 2 in raw and treated wastewater; c) the volume of aerosolized water inhaled by a WWTP operator during work; d) humidity and temperature dependent viability of coronaviruses in aerosolized waste water; e) estimation of the amount, frequency, and duration of exposure; and f) exposure doses. The variables were then fed into an exponential dose response model to estimate the risks in three scenarios representing low grade, moderate and aggressive outbreaks. These scenarios were designed on the assumption of 0.03% 0.3% and 3% of the wastewater generating population being infected with SARS CoV 2. In terms of averaged out illness risk profiles, the individual illness risks for low grade, moderate and aggressive outbreak scenarios respectively are 0.036, 0.32 and 3.21 illness cases per 1000 exposed WWTP operators. Our study suggests that the risk of accidental occupational exposure to SARS CoV 2 in raw wastewater, via inhalation at the WWTP environment, is negligible, particularly when less than 0.3% of the population served by the plant are actively infected.
Principals' leadership styles: the role of emotional intelligence and achievement motivation
Venue: International Journal of Educational Management
Year: 2019

The purpose of this paper is to investigate the effect of emotional intelligence (EI) and achievement motivation (AM) on elementary school principals' leadership styles. This study investigates the contribution of EI and AM on the two major leadership categories: the task oriented and relationship oriented leadership.  This paper is a quantitative study with the implementation of correlation and hierarchical regression analysis. The surveys (i.e. EI scale, AM scale, leadership style questionnaire) were sent randomly to 280 elementary school principals in South Sulawesi, Indonesia, and 90 of them completed the survey (mostly male=77.78 percent) Findings Principals' EI significantly predicted both task oriented and relationship oriented leadership. In contrast, the principals' AM yielded non significant results in predicting both task oriented and relationship oriented leadership style. The results also suggested that the effect of EI on two major leadership styles (i.e. task and relationship orientation) outperformed the leader's AM.  This study did not consider the principals' performance in the analysis. Future studies should also address this issue by considering leadership performance as well as different culture and context. On the other hand, the authors developed new measures rather than using preexisting measures. Although the measures have been constructed according to the scale construction principles and reached an acceptable standard, future research should advance the psychometric property of the scales.  This study discusses the effect of EI and AM on task and relationship orientation leadership. In addition, this study has also brought a new insight into understanding leadership styles in collective culture such as Indonesia.
