Response Times Reconstructor Based on Mathematical Expectation Quotient for a High Priority Task over RT-Linux

Every computer task generates response times depending on the computer hardware and software. The response times of tasks executed in real-time operating systems such as RT-Linux can vary as their instances evolve even though they always execute the same algorithm. This variation decreases as the priority of the tasks increases; however, the minimum and maximum response times are still present in the same task, and this complicates its monitoring, decreasing its level of predictability in case of contingency or overload, as well as making resource sizing difficult. Therefore, the need arises to propose a model capable of reconstructing the dynamics of response times for the instances of a task with high priority in order to analyze their offline behavior under specific working conditions. For this purpose, we develop the necessary theory to build the response time reconstruction model. Then, to test the proposed model, we set up a workbench consisting of a single board computer, PREEMPT_RT, and a high priority task generated by the execution of a matrix inversion algorithm. This work demonstrates the application of the theory in an experimental process, presenting a way to model and reconstruct the dynamics of response times by a high-priority task on RT-Linux.

TEACHING SCREENWRITINGAS TRANSLATION AND ADAPTATION:CRITICAL REFLECTIONS --©2021 P. CATTRYSSE

This chapter discusses teaching screenwriting in terms of translation and adaptation. Since translation and adaptation scholars often use both terms interchangeably to signify semiosis or culture, section one suggests some more specific working definitions. Realigning terminology with everyday language, translation is redefined as an invariance-based phenomenon while adaptation is reconceived as a variance-based phenomenon, which entails better fit. More specific working definitions help at once specifying what one could be teaching or learning in more precise terms.<br><br>Definitional issues involve conceptual and epistemic boundaries, which stakeholders use to defend their interests. This ushers in section two, which discusses the current Western Romantic view on art and culture, and how having driven a rift between art and craft, it opposes the aforesaid conceptual boundaries, and disparages screenwriting, translation, and adaptation, lest they comply with the Romantic rule. Suggestions follow to re-open the Romantic view to its pre-Romantic stance, and to revalue both art and craft values in screenwriting, translation and adaptation.<br><br>Section three concludes with some caveats.

Low-Wage Agricultural Migrant Workers in Apulian Ghettos, Italy: General Health Conditions Assessment and HIV Screening

Background: Approximately 500,000 migrants work in the agricultural sector in Italy. Many of them live in shantytowns, wrongly called “ghettos”, far away from city centers, with no water, proper hygienic conditions or health services. The aim of this study is to assess general health conditions and HIV prevalence by giving hygienic and sanitary sustenance. Methods: Between June 2019 and February 2020, we performed a screening campaign for HIV–diabetes–hypertension, involving migrants living in three Apulian establishments: ghetto Pista, “Sankara House” and “Arena House”. Results: Overall, 321 migrants were enrolled in the study. In the medical screening, one HIV test resulted positive. Hypertension was found in 12% of the migrants visited, diabetes in 2% and TB symptoms in 17%. Among others symptoms explored, muscle and joint pain/fatigue resulted in being the most frequent, and was reported by 34% of the migrants, followed by cough (10%). Significant predictors of muscle and joint pain/fatigue were: low BMI values (OR = 1.32; 95% CI 1.19–1.99), the absence of education (OR = 1.85; 95% CI 1.02–2.95), being employed with a regular contract (OR = 2.64; 95% CI 2.39–2.83) and living in the ghettos since >12 months (OR = 1.74; 95% CI 1.24–2.21). Conclusions: Our experience suggests that, in this population, the health condition is mainly linked to the specific working activities in the agricultural fields, as well as to the hygienic and living conditions, and that all of this is due to the lack of social protection in their life and job.

EVALUATION OF THE PERFORMANCE OF THE PROPULSION LEDOREZNOY MACHINES

Purpose: the aim of the analysis justify the selection of the type of propulsion ledoreznoy the machines with a specific working body. Design / methodology / approach: we present the averaged values of thrust for various types of working bodies LRM (disk, bar, bolt cutters). The calculated values of the thrust force of LRM equipped with various propellers (wheel, crawler, rotor-screw) are presented. Findings: the Advantage of the rotor-screw propellers is the absence of a rigid dependence of the thrust force on the weight of the machine. In addition, the rotors can provide a margin of buoyancy when the ice breaks and the machine enters the water. Research limitations/implications: it was found that the rotor-screw propellers have an excessive supply of traction, while the wheel-its disadvantage. Some specific properties of working bodies which, impose special requirements to the choice of propellers, are analyzed. The questions of the influence of the type of propulsion on the safety of work in the ice areas. Originality / value: the presented criteria and conditions can be the basis for the method of choosing the type of ice-cutting machine with any working body.

Albanian Preschool Personnel’s Perceived Obstacles to Implementing Effective Inclusive Education

Access to high-quality early education promotes the academic success of children with disabilities; however, they are often overlooked in mainstream programs that lack essential support services. This study aimed to examine the obstacles to supporting inclusion and providing effective early education programs for children with disabilities in Albania as perceived by the preschool personnel. Preschool personnel (n = 107) working with children (3–6 years old) in the municipality of Tirana, in Albania, completed the survey. The obstacles to supporting children with disabilities were identified as lack of knowledge, supportive techniques, specific working tools, suitable facilities, and support staff, insufficient cooperation with parents, and inadequate educational programs for children with disabilities. The contextual factors and practical implications of the study, as well as future directions for research, are discussed in this article.

Applying analytical hierarchy process (AHP) in selecting best maintenance strategies for newly established chemical fertilizers plants

PurposeThe purpose of this paper is to help newly established plants with minimal or no historical machine data select best maintenance strategies that suit their specific working setup and at the same time satisfy relevant selection criteria.Design/methodology/approachAnalytical hierarchy process (AHP) was applied successfully in this study to select the maintenance strategy at a newly established chemical fertilizers plant. Implementation started by identifying main and sub-criteria pertinent to maintenance practice in this particular industry. Pair-wise comparisons and consistency calculations were carried out on the chosen criteria and then were used to assess candidate maintenance strategies through a special scoring process. The methodology included the use of surveys, brainstorming and expert consultation.FindingsThe results have shown that the most important main criteria are cost, resources, failures, management, operations, quality and safety. The final maintenance strategy selected for the plant under consideration included a mix of condition-based predictive maintenance (PDM), time-based preventive maintenance (PM) and corrective maintenance (CM). The best balance between the three maintenance activities, which satisfies the maintenance criteria with technical applicability, was found to be 50, 23 and 19% for PDM, PM and CM, respectively.Originality/valueThe present paper is a novel application of AHP coupled with deterministic application-specific ranking for devising a procedure for selecting viable and applicable comprehensive maintenance strategies for newly established chemical fertilizers plants with no historical data on machine failures.

Aberrant modulation of brain activity underlies impaired working memory following traumatic brain injury

Impaired working memory capacity is a common and disabling consequence of traumatic brain injury (TBI) that is caused by aberrant neural processing. However, due to high heterogeneity in results across studies, it is challenging to conclude whether impaired working memory in this population is driven by neural hypo- or hyper-activation, and the extent to which deficits are perpetuated by specific working memory subprocesses. Using a combined functional magnetic resonance imaging and working memory paradigm, we tested the hypothesis that the pattern of neural activation subserving working memory following TBI would interact with both task demands and specific working memory subcomponents: encoding, maintenance, and retrieval. Behaviourally, we found that working memory deficits were confined to the high cognitive load trials. Our results confirmed our key prediction. Overall, TBI participants showed reduced brain activity while performing the working memory task. However, interrogation of the subcomponents of working memory revealed a more nuanced pattern of activation. When we simply averaged across all task trials, regardless of cognitive load or subcomponent, TBI participants showed reduced neural activation. When examined more closely, patterns of brain activity following TBI were found to interact with both task demands and working memory subcomponent. Participants with TBI demonstrated an inability to appropriately modulate brain activity between low and high demand conditions necessary during encoding and maintenance stages. Therefore, we demonstrate that conclusions about aberrant neural processing are dependent upon the level of analysis and the extent to which general cognitive domains can be parcellated into its constituent parts.

Simulation Modelling of Aerial Works and Its Role in the Preparation of Construction

The construction process is characterized by a diverse technological composition and the use of a wide range of construction machinery and mechanization. The amount of machinery increases with the complexity of the construction, which increases the demands concerning the preparation and overall organisation of the construction. The preparation of construction processes carried out by helicopters (aerial work) must respect the effect of randomly changing construction conditions as well as the specific working conditions of helicopters. The complexity of such a system can be modelled using simulation models. In the work presented, we designed and practically tested a simulation model of aerial work in the MATLAB software environment. An essential part of the simulation model is an algorithm designed on the basis of commercial numerical weather prediction models. We consider the outputs of the simulation to be reliable, because they are very close to the actual results achieved in the case of the implementation of construction of this type. The concept of the simulation model enables its wider use not only in the construction sector, but also in other branches of industry.
