Machine Learning Models for Scheduling On-Demand Fog Placement and Optimizing Container Deployment. (c2020)
Authors:   ,   Lebanese American University, Farhat Peter
Published: July 2022

Fog computing is an extended cloud computing technology allowing services embedded into virtual machines or containers to be placed at the edge with closer proximity to the end devices. Nevertheless, one of the main difficulties adding up to the complexity of the on-demand fog placement topic is deciding on the proper time and place of the fog deployment process, and deriving the adequate container and service distribution over the available fogs at a certain location. Several techniques have been suggested in the current literature as potential solutions, in which some consider users preferences or random-based approach for fog deployment, while others reside on threshold-based mechanisms. However, due to the huge increase in the number of requests coming from end devices including IoT users, fog deployment and container placement must be scheduled to serve locations with high service requesting profiles while decreasing the cloud processing load. In this context, we first propose a fog placement model that allows to produce an adequate scheduling decision by using a hybrid technique combining time series forecasting and reinforcement learning. The proposed technique learns the intensity of service invocations and behavior of end devices at different locations over time for predicting the localization plan. Second, we propose a K-Means based clustering model embedded within a multi-objective optimization scheme for fog and container placement. A comparison of our proposed solution with random-based and threshold-based fog placement scheduling approaches show that the number of processed requests performed by the cloud decreases from 100% to 29% compared to 93% and 67% in the other two models. The aforementioned results explore the efficiency of our proposed scheme in scheduling the fogs in their rightful place, which helps in decreasing the cloud’s load, decreasing the network congestion, and increasing the overall quality of service. Moreover, experimental results illustrate that the proposed optimization model and clustering technique further improve the pre-existing heuristic-based solutions for container distribution.

Published: July 2022

Online learning is recognized as an effective teaching method and tool, widely integrated into different teaching and learning strategies to provide quality education at different levels. However, the field of design education does not have extensive research into online learning, delivery, and assessment. This study developed an online learning model for design disciplines to improve creative work effectively. This paper describes an empirical study to test the BEE model outcomes developed following previous research. This present study has focused on the intensity of the live virtual classroom in every step to compare differences in the scores of creative works. Therefore, the assumption was that Thai undergraduate design students who learned with the BEE model through live classroom learning (experimental group) would have at least one element of the creative work scores compared to the group learning through the traditional online teaching method (control group). Furthermore, we conducted a multistage randomized sample of 66 participants, divided into an experimental group of 33 participants and a control group of 33 subjects. To compare the scores of creative works, the test of creative works assessment rubric was used to collect the data. Then, they were analyzed using the MANOVA statistical test. The results found at least one element of them, and the average creative work scores of the experimental group showed that they were significantly higher than the control group (p<0.05). Doi: 10.28991/ESJ-2022-SIED-08 Full Text: PDF

The research’s title is An Analysis of Household Financial Management and State Finances During the Covid-19 Pandemic According to the Sharia Economic Perspective. The background of this research is the condition of the outbreak of the COVID-19 pandemic in all countries in 2020. The move to close the economic sector has an impact on household finances and state finances.

The purpose of this study is to analyze household financial management and state finances during the COVID-19 pandemic from a sharia economic perspective. The method used in this study is a descriptive qualitative method approach using content analysis techniques.

From a study conducted on various literatures, the following points are shown. First, should follow the example of the Prophet in managing family financial spending by using the principles of a simple lifestyle. When managing shopping, prioritize needs, not wants. Second, the expenditure should be regulated based on the amount of income. When an epidemic occurs which results in reduced income, some spending must be cut. Third, keep spending your wealth on infaq, shodaqoh etc when you are free or when you are short of sustenance. Fourth, set the largest allocation for mass basic needs. As for the regulation of state finances according to the sharia economy in an epidemic condition, all income owned by the state is allocated to meet the basic needs of the people. Especially the basic needs of each household and the fulfillment of health needs. In the Islamic economic system, there is a solution to rearrange regulations on macro and micro economic aspects to become sharia-based.

In this paper, the authors consider the factors influencing the introduction of advanced production technologies in the federal districts of the Russian Federation. A statistical analysis was carried out on the topic under study, as a result of which the indicators of the level of innovative activity of organizations and the share of innovative products in the total mass of goods were studied. It is revealed that the Volga Federal District is the leader, the North Caucasus, Ural, Siberian and Far Eastern Federal Districts are among the laggards. The probability of the influence of individual risk factors that have a negative impact on the introduction of production technologies at enterprises is calculated. It is revealed that the main risk factors are difficulties in hiring qualified personnel, low return on investment or a long payback period and the complexity of integrating technologies into the organization's processes.
The Plausibility of Being Wrongly Convicted for A Sexual Offence
Authors: Speechley Naomi-Ellen , Burnett Ros
Published: July 2022

The present article reports the findings from a study of ex-prisoners convicted for sexual offences but maintaining innocence (‘CMIs’). The research was focused on the impact of being wrongly accused of sexual abuse, for the convicted persons and their relatives. While the researchers obviously cannot vouch for their innocence, they refer to policy and legal developments in the UK, and in other countries, that might have increased the possibility of wrongful convictions for alleged sexual offences, particularly in the case of alleged historical (non-recent) cases. The dire experiences reported by participants, and the justifications for researching unexonerated former prisoners maintaining innocence, are discussed.
The Reliability of Expert Evidence in Canada
Authors: Savage Samantha
Published: July 2022

This paper analyzes Canada’s common law as it currently stands regarding expert evidence and key inquiries and reports on expert evidence and wrongful convictions done in Canada and on forensic science. The analysis will demonstrate how Canada’s laws and practices have not gone far enough to ensure expert evidence is reliable in order to protect innocent citizens from wrongful conviction. I propose that to truly safeguard against the admission of improper expert evidence in trials Canada must (1) heighten the standard expert evidence must meet to be considered reliable and increase a judge’s role as gatekeeper (2) foster a system of peer-reviewed research, training, accreditation, and accountability in forensic science disciplines in Canada, and (3) ensure that all legal actors (i.e., police, lawyers, and judges) receive continued training on best forensic science practices and their limits and have free access to information and education on forensic science disciplines when needed. Systemic changes in forensic science disciplines in Canada, continued education in forensic sciences for legal actors, and changes in the law of reliability of evidence are necessary to prevent improper expert evidence from continuing to contribute to wrongful convictions. This paper concludes by with a case study evaluating how the proposed systemic changes could have made a difference in a real-world case where expert evidence was flawed.

Research suggests that formerly incarcerated individuals, and individuals belonging to racial minority groups, experience stigma and housing discrimination. The current study explored landlords’ attitudes and differential communications toward formerly incarcerated individuals – particularly wrongfully convicted individuals – of varying races. Using data from an experimental audit study, we examined the content of landlords’ email responses to rental inquiries from fictitious convicted and wrongfully convicted individuals, and members of the general public (i.e., control), who were either Black, Indigenous, or White. A content analysis revealed three main themes: 1) responding with courtesy; 2) probing for additional information; and 3) willingness to set up a viewing. Logistic regressions revealed that landlords were more likely to justify the rental’s unavailability, inquire about the renter’s financial stability and references, and to say they would follow up later when corresponding with convicted and wrongfully convicted individuals compared to control. Landlords were also more likely to ask White renters about their criminal history compared to Black and Indigenous renters. Surprisingly, individuals belonging to racial minority groups were not disadvantaged further in this data. The findings are discussed in the context of post-incarceration support.

Published: July 2022

Purpose: Studies exploring the adverse effects of oral contraceptive pill (OCP) use among women living in Erbil/Iraq are lacking. This study aimed to assess the patterns of use and associated side effects among women in Erbil.

Patients and methods: A face-to-face questionnaire survey inquiring about demographic information and issues related to the use of OCPs and related side effects was completed by 235 women who had used OCPs at least once in their lifetime.

Results: The women exhibited positive attitudes towards OCP efficacy and safety, positively associated with their patterns of use. The following common side effects of OCPs were reported: pain (69.4%), vision problems (60%), headache and fatigue (59%), speech impairment (53%), irregular bleeding and breast tenderness (52%), nausea (51%), chest pains (40%), chloasma (37%), weight gain (33 %), abdominal pain (28%), shortness of breath (26%), swelling (20 %), spotting (12%), and allergy (7%).

Conclusion: The study revealed that women who have many side effects toward OCPs nevertheless tend to use them appropriately. However, educational programs are advisable to improve knowledge about OCP use among women in Erbil.
Assessment of the type of reservoir fluid extracted from wells of a gas and oil deposit by the component composition of gas samples

Published: July 2022

The article presents the results of complex multi-scale studies of carbonate natural reservoirs of large and supergiant oil and gas fields of the Mesopotamian trough. Various depositional environments have been identified in the Upper Cretaceous sediments of the Mishrif formation. Facies of tidal channels have been identified and substantiated for the first time at one of the deposits. It is shown that high productivity values are associated with their distribution zones. A fundamentally different type of reservoir is noted in the same-age deposits at another deposit. Here, the main productivity is associated with facies of coral-rudist buildups and shoals. As a result of detailed sedimentological studies and reconstruction of paleobiocenoses of reef-building organisms, the main patterns of the reservoir architecture were revealed. In the Lower Cretaceous deposits of the Yamama formation, coral-stromatoporoid-algae facies and peloid-oolitic shoals have been identified and contoured. Their distribution explains the presence of separate isolated deposits, as well as different positions of water-oil contacts.
Determination of permeability from well logging data based on the petrophysical invariant

Published: July 2022

The reliability of determining the permeability and porosity properties of oil and gas reservoirs depends on the informative value of the sets of petrophysical and geophysical well surveys and the efficiency of the methods for interpreting the obtained data. In order to determine the permeability from well logging data without using a correlation between permeability and porosity, the paper proposes the Kozeny–Carman equation, transformed on the basis of a petrophysical invariant (normalized effective porosity). The equation makes it possible to take into account the heterogeneity of the pore space of the intergranular reservoir with an appropriate petrophysical setting for the content of the main granulometric fractions.

Published: July 2022

At the moment, hard-to-recover reserves start playing bigger role in oil production all over the world. In Russia, they account for more than 65% of the total proved reserves. Therefore, the effective development of hard-to-recover reserves is one of the most important and promising tasks of oil producing enterprises. The Achimov formation in Western Siberia has large oil production potential, but traditional approaches are not efficient enough to develop such complex reservoirs. The purpose of the work is the development analysis and the best option selection for the development of oil deposits of hard-to-recover reserves. The article considers various ways to solve the problem. The most promising are the two options – the drilling of multilateral wells and the drilling of horizontal wells with low-volume hydraulic fracturing. As a result of the analysis of the geological structure and calculation on the hydrodynamic model, it is concluded that the most optimal way is to drill multilateral wells. Economic calculations confirm the feasibility and profitability of the project.
