MODIFIED SCHEDULING PROTOCOL TO OPTIMIZE THE EXECUTION OF TRANSACTIONS WITHOUT EXCEEDING THEIR DEADLINES
Authors: Синюков Д.С.
Published: September 2022

Приложения все чаще характеризуются манипулированием большими объемами данных и временными ограничениями, в связи с которыми представляются данные и методы лечения. СУБД РВ (Системы управления базами данных в реальном времени) являются подходящим формализмом для обработки таких приложений. Однако СУБД РВ часто проходит через периоды перегрузки после неожиданного поступления пользовательских транзакций. В такие периоды транзакции с большей вероятностью пропускают свои предельные сроки, и это напрямую влияет на QoS (качество обслуживания), предоставляемое пользователям. Таким образом, задача заключается в том, чтобы предложить модифицированный протокол планирования для оптимизации выполнения транзакций без превышения их предельных сроков. Он заключается в назначении приоритетов транзакциям на основе как их предельных сроков, дат прибытия, так и уровней приоритета, определенных пользователями. Кроме того, экспериментально показано, что такой подход может максимизировать количество успешных транзакций, в частности тех, которые классифицируются как критические для пользователей. Полученные результаты сравниваются с традиционными подходами к планированию.

Applications are increasingly characterized by manipulating large amounts of data and by time constraints to which are submitted data and treatments. СУБД РВ (Real-Time DataBase Management Systems) are an appropriate formalism to handle such applications. However, a СУБД РВ often goes through overload periods following the unexpected arrival of user transactions. During such periods, transactions are more likely to miss their deadlines and that directly affects the QoS (Quality of Service) provided to users. Thus, our work is to propose a new scheduling protocol to optimize the execution of transactions without exceeding their deadlines. It consists on assigning priorities to transactions based both on their deadlines, their arrival dates and their priority levels defined by users. Also, we show that our approach can maximize the number of successful transactions, in particular those classified as critical for users. The obtained results are compared with conventional scheduling approaches.

The article discusses the concept of smart cities, based on which it is supposed to de-velop large settlements and regions in the era of globalization and digitalization. The authors admit that smart cities offer their residents great opportunities. Criticism of smart cities is associated with the ill-considered use of artificial intelligence tech-nologies and shifting responsibility for deci-sions made in cities to it, with limited oppor-tunities to take into account the opinions of residents in urban management systems, with threats of losing the confidentiality of personal data of citizens and companies. The theoretical significance of the study lies in the definition of modern problems of "smart cities", previously not covered by the attention of experts. Of practical interest is the formulation of proposals related to the revision of modern educational strategies, taking into account the implementation of the goals of forming in cities a community of residents involved in the process of solving urban problems.

Peran Konteks Dalam Memahami Hadis Misogini: Kajian Pragmatik
Authors: Mutmainah Mia
Published: September 2022

Hadis sebagai sumber rujukan hukum Islam banyak dinilai mendiskreditkan perempuan. Hadis-hadis ini kemudian disebut sebagai hadis misogini. Salah satu hadis yang dianggap misogini adalah hadis yang mengatakan bahwa perempuan merupakan mayoritas penghuni neraka. Hadis tersebut merupakan hadis sahih sehingga perlu pengkajian mendalam terkait makna konstektual hadis. Penelitian ini bertujuan untuk menganalisis aspek serta peran konteks dalam memahami hadis tersebut. Analisis konteks yang dilakukan dalam penelitian ini merujuk aspek konteks dalam kajian ilmu Pragmatik. Dari analisis konteks tersebut dihasilkanlah makna kontekstual hadis. Penelitian ini merupakan penelitian kualitatif. Hasil penelitian menunjukkan bahwa aspek konteks yang melatarbelakangi hadis adalah aspek penutur, lawan tutur, serta situasi tutur. Sehingga, makna kontektual dari hadis yang menyatakan bahwa mayoritas penghuni neraka itu perempuan adalah bahwa hadis tersebut merupakan bentuk peringatan serta nasihat kepada kaum perempuan pada masa itu yaitu masyarakat Madinah yang sering kufur akan nikmat dan banyak menggunjingkan suami mereka. Artinya, hadis tersebut sangatlah kontekstual sehingga tidak bisa hanya dipahami secara tekstual.

Field-oriented control is one of the well-established vector control strategies for induction motor drives. However, its cascaded structure and requirement of a modulator for constant switching frequency operations makes it complex and computationally expensive. Model predictive control (MPC) is a novel control strategy used for AC motor drives. In this paper, a finite control set model predictive control (FCS-MPC) based field-oriented control (FOC) is presented. The Finite control set model predictive field-oriented control (FCS-MPFOC) utilizes a cost function that quantifies the error between the reference and anticipated current values for all the potential voltage vectors of the voltage source inverter. The voltage vector that generates the lowest value of the cost function is directly implemented on the inverter to produce the drive voltage. The efficiency of the proposed method is authenticated by using a three-phase induction motor, fed via a two-level three-phase voltage source inverter in the MATLAB/Simulink environment under various speeds, load torque, and model parameter mismatch situations. In order to authenticate the performance of the proposed strategy, it is compared with traditional model predictive torque control. Simulation results show that the proposed method performed significantly well in total current harmonic distortion, flux and torque ripples, switching frequency, and parameter variations.

Low-pressure gas wells are of increasing interest to the petroleum industry as economic and environmental importance of natural gas continues to grow. To maximize the production of low permeability gas reservoir, a novel production strategy to determine reasonable producing periods, including the pressure draw down process and the pressure build up process, in low pressure gas wells has been investigated. Additionally, the variation of down-hole pressure and gas flow in both processes were considered to formulate the optimization model to find reasonable switching times for low-pressure gas wells in this research. In order to enhance the adaptability of the production strategy proposed in this research, parameters of erosion flow rate, critical flow rate of liquid loading and reasonable differential producing pressure of the reservoirs were considered in the proposed mathematical model which aims at maximizing gas production of low-pressure gas wells. Based on the application of the mathematical model dealing with reasonable production strategy of low-pressure gas wells, the pressure of gas well varies smoothly in both shut-in process and gas production process when the novel production strategy was applied. And nature gas production of the gas well increases dramatically compared with that before.

Published: September 2022

Il y a beaucoup de problèmes qui entravent l’éducation des femmes et celle des enfants au Nigeria. Parmi ces problèmes compte la violence domestique. Selon le rapport de Women’s Aide (2013) il y a violence domestique lorsqu’une personne essaie de contrôler ou d’exercer un pouvoir sur son partenaire dans une relation intime. Les victimes de la violence domestique au Nigéria subissent très souvent de mauvais traitement psychologique, problème physique et mentale, problème d’ordre cognitif (problème de concentration) et de problème du comportement social tels que le stress, l’anxiété, la dépression, le traumatisme, la difficulté d’adaptation au seine familiale que peuvent poser de problèmes sur la performance académique résultant au retard ou à l’échec scolaire (Aihie, 2010). Les violences domestiques auxquelles nous réfèrerons dans ce travail impliquent les femmes et les enfants victimes et homme agresseur. Ce travail cherche parmi autres à expliquer ce que constitue abus domestiques. Elle cherche aussi à soulever les différents actes d’abus domestiques comme ils apparaissent dans le roman de corpus tout en proposant des remèdes à ce problème. Pour ce faire, nous allons analyser les grands thèmes de l’œuvre de “l’Hibiscus Pourpre” pour faire sortir les éléments de violences domestiques comme traités dans le roman.
Do Oil Price Shocks Affect Exchange Rates in Oil-importing Countries: A Case of the Zambian Economy using the SVAR Approach
Authors: Chundama Stephen
Published: September 2022

Oil price shocks have been argued to impact Real Effective Exchange Rates (REERs) in net oil importing countries, mostly through the wealth-transfer effect, which involves the transfer of wealth from net oil-importers to net oil-exporters, and the Terms of Trade Channel. Since this analysis had not been done for the Zambian case by decomposing oil price shocks, a Structural Vector Autoregressive Model (SVAR) was used to measure the contemporaneous impact of oil price shocks on REERs, and was complemented by Impulse Response Functions (IRFs), Granger Causality Tests and Forecast Error Variance Decomposition (FEVD). The long-run impact was analyzed by the Vector Error Correction Model (VECM) after satisfaction of cointegration requirements. The findings revealed that decomposed oil price shocks had no short-run contemporaneous impact on REERs at the 5% level. Similarly, it was found that decomposed oil price shocks and the combined effect of all the variables in the system did not granger-cause Zambia’s REERs, while FEVD results showed that oil price shocks were attributed for a minute proportion of the variation in REERs. These findings were attributed to Zambia’s profile as a predominantly copper and cobalt exporter, historic exchange rate controls, fuel subsidies, and price controls. Johansen’s cointegration test revealed the existence of at least one cointegrated equation in the system, so the subsequent VECM which was constructed revealed that decomposed oil price shocks had no long-run impact on REERs in Zambia, but that the Error Correction Term (ECT) which measures the speed to adjustment back to equilibrium after a short-run disturbance, was significant.

Published: September 2022

Regression models are commonly used in prediction, but their predictive performances may be affected by the problem called the multicollinearity. To reduce the effect of the multicollinearity, different biased estimators have been proposed as alternatives to the ordinary least squares estimator. But there are still little analyses of the different proposed biased estimators’ predictive performances. Therefore, this paper focuses on discussing the predictive performance of the recently proposed “new ridge-type estimator”, namely the Kibria-Lukman (KL) estimator. The theoretical comparisons among the predictors of these estimators are done according to the prediction mean squared error criterion in the two-dimensional space and the results are explained by a numerical example. The regions are determined where the KL estimator gives better results than the other estimators.

The operation of the most of wells justified that the production of flooded well output is followed with an intensive salt deposition. The formation of salt sediments occurs in various systems of production and collection of output. The paper provides the physical-chemical parameters of produced water from the oil wells in “28 May” OGPD of “Azneft” PU. Therefore, the application of an inhibitor for the injection into the bottomhole zone of producing well with a pump unit is considered reasonable. KD-1 salt inhibitor is injected both into the annular space and bottomhole zone of the reservoir. The implementation of an agent against salt sediments developed in “Oil-Gas Scientific Research Design” Institute is carried out by means of KD-1 salt inhibitor with specific weight of 100 g/t. It is a multi-component synergetic composition meeting all modern requirements to the physical-chemical properties of agents. The increase of oil recovery for each well after the introduction of KD-1 salt inhibitor in “28 May” OGPD approximately comprised 0.5 t/day.
Evaluating Pakistani Media’s Perception of Chinese Military Development: A Content Analysis of Pakistani Newspaper
Authors: Jamal Muhammad Ahsan , Abbas Syed Bahadur , Ullah Asad
Published: September 2022

China’s military modernization has led to many concerns among regional and international stakeholders. Many countries see Beijing’s intentions to become a military superpower as threatening regional peace and stability. On the other hand, being China’s strategic ally, Pakistan sees its military expansion as a positive change to back its drive to become a regional military power. This research aims to analyze the perception of Pakistani media about the Chinese military by conducting an extensive content analysis of the Pakistani newspaper ‘Pakistan Today. The data helped highlight the Pakistani media’s attitude toward China’s military ambitions. The analysis suggests that Pakistani newspaper projects China’s military might as the balance of power, particularly against its regional rival, i.e. India. The research elucidates that while most Western media coverage portrays Chinesemilitary activities as a challenge to the regional status quo, Pakistani media exhibits it as important for peace and stability in the region.
Clustering Behavior in Solar Flare Dynamics
Authors: Rivera Elmer C. , Johnson Jay R. , Homan Jonathan , Wing Simon
Published: September 2022

The solar magnetic activity cycle provides energy input that is released in intense bursts of radiation known as solar flares. As such, the dynamics of the activity cycle is embedded in the sequence of times between the flare events. Recent analysis shows that solar flares exhibit memory on different timescales. These previous studies showed that the time ordering of flare events is not random, but rather there is dependence between successive flares. In the present work, the clustering of flares is demonstrated through a straightforward nonparametric method where the cumulative distribution function of successive flares is compared with the cumulative distribution function of surrogate sequences of flares obtained by random permutation of flares. The random permutation is performed within rate-variable Bayesian blocks during which the flare rate is assumed to be constant. Differences between the cumulative distribution functions are substantial on a timescale around 3 hr, suggesting that flare recurrence on that timescale is more likely than would be expected if the waiting time were drawn from a nonstationary Poisson process.
Unveiling the Contribution of Population III Stars in Primeval Galaxies at Redshift ≥6
Authors: Riaz Shafqat , Hartwig Tilman , Latif Muhammad A.
Published: September 2022

Detection of the first stars has remained elusive so far but their presence may soon be unveiled by upcoming JWST observations. Previous studies have not investigated the entire possible range of halo masses and redshifts that may help in their detection. Motivated by the prospects of detecting galaxies up to z ∼ 20 in the JWST early data release, we quantify the contribution of Population III stars to high-redshift galaxies from 6 ≤ z ≤ 30 by employing the semianalytical model a-sloth, which self-consistently models the formation of Population III and Population II stars along with their feedback. Our results suggest that the contribution of Population III stars is the highest in low-mass halos of 107–109
M
⊙. While high-mass halos ≥1010
M
⊙ contain less than 1% Population III stars, they host galaxies with stellar masses of 109
M
⊙ as early as z ∼ 30. Interestingly, overall the apparent magnitude of Population III stars gets brighter toward higher redshift due to the higher stellar masses, but Population III–dominated galaxies are too faint to be directly detected with JWST. Our results predict JWST can detect galaxies up to z ∼ 30, which may help in constraining the initial mass function of Population III stars and will guide observers to discern the contribution of Population III stars to high-redshift galaxies.

The inevitability of switching to carbon-free energy to withstand the climate change is no longer disputed by anyone today. There is no alternative to this, and the scientific community is forming an appropriate understanding of the need for the development of nuclear energy as carbon free energy source. Solutions are already being discussed at the level of the President and the Government of Russia. In this regard, the article shows that such a solution is possible only based on a new technological platform – two-component nuclear power with the development of technologies of fast reactors with a closed fuel cycle. At the same time the prevailing view in the public opinion of Russia, and not only in it, is that climate change problem can be solved only at the expense of solar and wind energy. This attitude needs to be changed, because without the understanding and support of society, it is impossible to achieve a wide spread of fast reactors with closed fuel cycle technologies. It is concluded that in order to promote a new technological platform in commercial energy and ensure the export prospects of fast reactors of Russian design with closed nuclear fuel cycle facilities, it is necessary to attract representatives of business circles and large energy businesses to the number of supporters of such development by demonstrating the profitability of solutions in the medium and long term, implemented in the case of the use of Russian technologies of fast reactors with the closure of the nuclear fuel cycle.
Adolescence et soin sous autorité judiciaire
Authors: Ez-Zajjari Siham
Published: September 2022

La conception et la mise en œuvre des soins psychiques auprès d’adolescents sous-main de justice posent certaines questions d’ordre éthique et pratique pour les professionnels, notamment pour les psychologues cliniciens qui contribuent à leur prise en charge institutionnelle. Notre propos prendra principalement appui sur la pratique clinique à la Protection Judiciaire de la Jeunesse dans les « hébergements » pour adolescent(e)s placés sous autorité judiciaire dans un cadre pénal. En alternative à l’incarcération, la mesure de placement provisoire en institution (ré)éducative est alors ordonnée par un mandat judiciaire. Cette mesure peut être accompagnée d’un certain nombre d’obligations, dont l’obligation de soin. Mais comment le soin psychique peut-il s’opérer pour ces adolescents au regard de leurs caractéristiques psychopathologiques ? Le processus soignant peut-il être contraint par un tiers ou prend-il plutôt appui sur l’autorité judiciaire pour devenir opérant ?

Cet article porte sur les usages de la métaphore du circuit électrique pour décrire la communication humaine, en particulier dans les études littéraires. Après un panorama historique de ces usages en sémiotique structurale (R. Jakobson), en histoire du livre (R. Darnton) et en sociologie de la littérature (R. Escarpit, H. Becker, P. Bourdieu) l’article se penche sur les recherches qui ont porté sur l’un ou l’autre pôle du circuit de la communication littéraire (l’auteur, le lecteur). Est enfin proposée une perspective décloisonnée, consciente des apports et des limites du modèle communicationnel.

This study investigated the response of Physalis angulata L. to salt stress in terms of its growth, physiology, and production using a randomized block design with three replicates. For greenhouse cultivation, 21-day-old seedlings were cultivated in polybags containing Mediterranean soil and subjected to salinity treatments at concentrations set at 0, 20, 40, 60, 80,100,120,140,160, and 180 mM. Growth, physiology, and production parameters were measured 90 d after planting. Growth, stomatal density, yield, and fruit physical attributes were reduced at 80 mM and higher salinity. Salinity also increased the physiological responses and chemical features of the fruit. However, P. angulata grew faster and exhibited better yield and fruit quality at a salinity of 20 mM (2.25 dS m−1). Therefore, P. angulata can be cultivated in moderately saline soils, allowing for efficient land use.
GDP growth rate, tourism expansion and labor market dynamics: Applied research focused on the Italian economy
Authors: Colacchio Giorgio , Vergori Anna Serena
Published: September 2022

This paper focuses on the Italian economy and investigates the causal nexus between economic growth, tourism development and labor market dynamics. We performed a two-step analysis. In the first step, we evaluate whether tourism stimulates Italian economic growth or if it is the economic growth that promotes tourism expansion. To get the goal, we use panel data from 1997 to 2019 concerning the GDP and overnight stays in each Italian region. We performed the Granger causality test on the whole panel and analyzed a panelvar model. In the second step, after having established the relationship between the two variables of interest, we extended our analysis to investigate—throughout the estimate of the employment intensity of growth and the impact of GDP growth on employment, at both aggregate and disaggregate level. The main findings of our analysis are as follows: a) the existence of a unidirectional causality going from economic growth to tourism development (i.e., validation of economic-driven tourism growth hypothesis), and b) a significant estimated magnitude of the (average) employment intensity of growth.

The chapter analyses gross domestic saving, household consumption, and inequality in African countries. The study covers the period from 1989 to 2019, a length of 31 years, for 24 Africa nations from all the regions of the continent. The main econometric methods of analysis employed for the work is panel cointegration analysis. The variables used for the study to explain both gross domestic savings and household consumption trajectories in Africa include income, inequality, financial development, and government final consumption expenditure. The results show that inequality has negative effects on gross domestic saving but positive effects on household consumption in countries across Africa.

Liquid-solid mass and heat (by analogy) transfer at the bottom of a cylindrical stirred vessel were studied by using the well-known electrochemical technique. Variables studied included the impeller geometry and its rotational speed. Results revealed that the radial flow impeller is preferable over the axial flow one in terms of mass transfer enhancement, additionally, increasing the impeller rotational speed led to an increase in the mass transfer coefficient. Results were correlated by dimensionless equations. Application of these equations in the design and operation of an improved catalytic biochemical reactor suitable for conducting diffusion-controlled immobilized cell (or enzyme) reactions was highlighted. These equations can serve in predicting the corrosion rate and corrosion allowance required to calculate the bottom thickness of the agitated vessel in its design stage. Furthermore, these equations can be used in estimating the heat lost from the tank bottom, accordingly, design an effective cooling jacket surrounding the agitated vessel bottom in case of exothermic biochemical reactions to avoid thermal degradation of the biomass.

Published: September 2022

Membranes are used in various different applications in water treatment due to the wide array of properties that can be attained from different materials and polymers. A new hybrid membrane for the purification of water by electrodialysis has been manufactured and studied in this research. The membrane consists of two different materials: A host polymer matrix and a cation selective metal organic framework, MOF. For the polymer matrix, polyvinylidene fluoride, PVDF, was selected to act as the body that is meant to be the backbone of the membrane. It was dissolved in different solvents with different concentrations to determine the most stable matrix. Using scanning electraon microscope, SEM, imaging, it was found that 10% wt in dimethylformamide (DMF) provided the most suitable conditions for this work. As for the cation selective MOF, UIO-66 was selected and then synthesized using hydrothermal method and characterized using X-ray diffraction, XRD, and found to match previous literature. UIO-66 provides the membrane with cation selectivity, which allows the membrane to function in an electrodialysis system, so it was dissolved with the PVDF matrix to provide a hybrid membrane. Different amounts of the MOF in the membrane matrix were tested to find the most suitable distribution of the MOF over the surface of the membrane and was found to be around 2%. The membrane was tested with LiCl salt, before and after UIO-66 addition, in a half cell to measure the influence of the UIO-66 as a cation selective material and its effect on ion migration.

Zirconia is one of the materials used in prosthetic restoration because of its better physical, mechanical, chemical, and biological properties. The surface treatment for zirconia can be mechanical, with grinding, sandblasting, and laser or chemically, with silane and etching. The combination of chemical and mechanical surface treatment can increase the surface roughness so that the bonding with the resin cement also increases. The study aims to examine the zirconia surface roughness after different surface treatments. This study used 25 zirconia samples in 10x10x2 mm square-shaped, divided into five groups. Group 1 treats sandblasting as a control. Group 2 sandblasting then etching with 9.5% hydrofluoric acid at 25°C for 60 minutes. Group 3 sandblasting then etching with 9.5% hydrofluoric acid at 100°C for 1 minute. Group 4 etching with 9.5% hydrofluoric acid at 25°C for 60 minutes. Group 5 etching with 9.5% hydrofluoric acid at 1000C for 1 minute. The samples were cleaned with an ultrasonic cleaner and tested using a profilometer. The data test by using the ANOVA test and T-test. The highest surface roughness was the combination of sandblasting with 9.5% hydrofluoric acid etching at 25°C for 60 minutes. The lowest was 9.5% hydrofluoric acid etching at 100°C for 1 minute. ANOVA statistical analysis with a p-value <0.05 ((8.4051 x 10-12) indicates that the test was significant. The result of this study was the combination of surface treatments resulted in higher surface roughness. Duration of the etching time affected the increase of zirconia surface roughness.
