Enhanced framework to mitigate maintenance strategy failure of electric power plant during crises

In engineering, a design is best described based on its alternative performance operation. In this paper, an electric power plant is analysed based on its effective operational performance even during critical situation or crisis. Data is generated and analysed using both quantitative and qualitative research approach. During maintenance operation of an electric power plant, some components are susceptible to wide range of issues or crises. These includes natural disasters, supply chain disruptions, cyberattacks, and economic downturns. These crises significantly impact power plant operations and its maintenance strategies. Also, the reliable operation of power plants is often challenged by various technical, operational, and environmental issues. In this research, an investigation is conducted on the problems associated with electric power plants by proposing a comprehensive and novel framework to maintenance the power plant during crises. Based on the achieved results discussed, the framework impact and contribution are the integration of proactive maintenance planning, resilient maintenance strategies, advanced technologies, and adaptive measures to ensure the reliability and resilience of electric power plant during power generation operations in the face of unforeseen challenges/crisis. Hypothetical inferences are used ranging from mechanical failures to environmental constraints. The research also presents a structured approach to ensure continuous operation and effective maintenance in the electric power plant, particularly during crisis (such as environmental issues and COVID-19 pandemic issues).

Possibilities in an abductive perspective: Creating affordances as cognitive chances

Recent studies on the so-called EEEE (extended, embodied, embedded, and enacted) cognition have demonstrated that the “environmental situatedness” of human cognition and its evolutionary component may be used to better understand cognition in general. This indicates that humans do not keep in their memory ample representations of the surroundings and their variables, but instead, they richly manipulate it by picking up information and resources, when possible and needed, that are already accessible, or that are extracted/created: it is in this perspective that we can conceptualize in a useful and deep way the concept of possibility. Information, resources, cognitive opportunities, and possibilities are actively pursued for and even created: in light of this, we may consider human cognition to be a possibility-seeking mechanism. In particular, new possibilities can be usefully seen as new “affordances”: for example, environmental anchors that enable us to more effectively utilize external resources. Of course, the availability of the proper affordances, which in turn offer cognitive possibilities, is connected to important new found concepts of discoverability and diagnosticability. Abduction is still significant in these cognitive processes because it refers to all those hypothetical inferences made by human and non-human animals that are based on deft manipulations of their surroundings, either to merely “detect” affordances or to “create” manufactured external objects (e.g. artifacts) that in turn provide new affordances and cues and so new cognitive possibilities.

The use of myths and taboos in wildlife conservation: The case of Bayelsa-East Senatorial District of Nigeria

The use of myths and taboos in species conservation represent a sustainable in situ means to wildlife protection. This study examined the role of taboos (traditional laws) in wildlife conservation within Bayelsa-East Senatorial District. Data were collected using a combination of semi-structured open-ended questionnaire guide and field observations, as well as species-evidence left behind. Informants for the study were selected from fifteen communities across the Local Government Areas (LGAs) that constitute the district. Local abundance status of the species implicated in the myths and taboos was determined within the various ecological settings, and likert scale was used to evaluate the informants’ perceptions on the taboos in relation to their effectiveness at protecting the identified species. The punishments for non-compliance with the taboos, as well as hypothetical inferences for the species conservation were documented. Ten (10) animal species in nine families were implicated in Bayelsa-East myths and taboos. The taboo animals were in 5 classes within Kingdom Animalia; members of the Class Reptilia (Crocodylus niloticus, Python regius, Python sebae and Varanus niloticus) were the most implicated; followed by Aves (Haliaetus vocifer, Macropygia doreya, Strix nebulosa). Abundance scale revealed that periwinkle (Gastropoda) was very abundant in Nembe and Brass. The informants’ perception on the effectiveness of the taboos (e.g. forbidding of hunting or killing Ekekoru, Python regius) in relation to the species protection revealed that the taboos were strongly effective in protecting the species in Nembe. The taboos in the study area were species specific, hence animals forbidden in Nembe and Brass LGA were not exclusively forbidden in Ogbia communities, and vice versa. The informants confirmed their beliefs and awe in the taboos and forbade abusive use, thus substantiating the taboos’ potential as sustainable tool for wildlife conservation.

Logical inferences according to the Cognitive Development model among Preparatory school students

The research aims to identify the level of logical inferences and its skills among students of the preparatory stage, and to identify the logical inferences & its skills according to the gender variable (male - female) and academic specialization (scientific – literary). The sample consisted of (400) male and female students who were selected by the random stratified proportional method from the three Karkh education directorates. The researcher built a logical inferences test that includes: (6) sub-skills: inference (Proportional, probabilistic, Synthetic, Hypothetical, Syllogistic, & Variables Controlling). The electrochemical properties of the test were verified. The following statistical methods were used: (Chi-square, Correlation Coefficient: Pearson, Biserial, Spearman Brown Correlation), one-sample t-test, two-way analysis of variance). The following results were obtained: 1) Preparatory school students possess a high level of logical inference; 2) Preparatory stage students have more structural & hypothetical inference skill than other skills; 3) The degree of logical inference males is higher than in females; 4) The degree of logical inferences among students of the scientific Branch is higher than that of students of the literary Branch; 5) Males outperform females in the skills of proportional and Synthetic inference;

On Basic Probability Logic Inequalities

We give some simple examples of applying some of the well-known elementary probability theory inequalities and properties in the field of logical argumentation. A probabilistic version of the hypothetical syllogism inference rule is as follows: if propositions A, B, C, A→B, and B→C have probabilities a, b, c, r, and s, respectively, then for probability p of A→C, we have f(a,b,c,r,s)≤p≤g(a,b,c,r,s), for some functions f and g of given parameters. In this paper, after a short overview of known rules related to conjunction and disjunction, we proposed some probabilized forms of the hypothetical syllogism inference rule, with the best possible bounds for the probability of conclusion, covering simultaneously the probabilistic versions of both modus ponens and modus tollens rules, as already considered by Suppes, Hailperin, and Wagner.

Composition of Deductions within the Propositions-As-Types Paradigm

Kosta Dosen argued in his papers Inferential Semantics Dosen (in Inferential semantics, Springer, Berlin 2015) and On the Paths of Categories Dosen (in On the paths of categories, Springer, Cham 2016) that the propositions-as-types paradigm is less suited for general proof theory because—unlike proof theory based on category theory—it emphasizes categorical proofs over hypothetical inferences. One specific instance of this, Dosen points out, is that the Curry–Howard isomorphism makes the associativity of deduction composition invisible. We will show that this is not necessarily the case.

Framing Deceptive Dynamics in Terms of Abductive Cognition

I propose an analysis of deception as the activity of intentionally misleading other agents’ hypothetical inferences. Understanding deception in this way has the advantages of clarifying the epistemological and cognitive dynamics involved in deception. Indeed, if deception can be framed as the intentional manipulation of others’ hypothetical inferences so that they will accept the false or disadvantageous hypotheses, then a better understanding of the epistemological and cognitive dynamics involved in deception will emerge by clarifying how abduction works. Tracing it back to Peirce’s analysis, I will focus on recent perspectives on abduction, which stress the inherent strategic character of abductive cognition and offer a realistic description of the reasoners’ capabilities and their scant resources, both internal (computational power) and external (time and information available). To support and substantiate my thesis, I will examine psychological analyses of military deception. I will conclude by remarking the advantages of the thesis here presented to better understand the epistemological dynamics of deception and by highlighting the questions it leaves open for further investigations.

Effect of Anionic Surfactant on Wettability of Shale and Its Implication on Gas Adsorption/Desorption Behavior

During the fracking process in shale, an interaction occurs between shale and fracking fluid that contains a cocktail of chemicals. One of the chemicals used in fracking fluid is often surfactant, which is generally used as a viscofier. However, surfactants also have the potential of significantly influencing the wettability and thus gas desorption–key factors affecting ultimate gas recovery from shale reservoirs. Even though a few studies discussed the ability of surfactants to alter wettability in shale, the implication of that change in adsorption/desorption behavior has never been experimentally investigated beyond hypothetical inferences. In this study, the influence of the wettability change by anionic surfactant on gas adsorption/desorption behavior in shale was investigated through a series of experiments. Baseline wettability readings of two shale samples were established by measuring the contact angles (BG-1 = 22.7°, KH-1 = 35°) between a drop of pure water placed on their polished surfaces, ind...

Mutually-inversistic machine learning is based on inverse hypothetical inference of mutually-inversistic logic constructed by the author. In mutually-inversistic logic, there are 8 kind of hypothetical inferences, all of which are from the major premise and the minor premise to infer the conclusion. For each hypothetical inference, there are 2 inverse hypothetical inferences, one is from the minor premise and the conclusion to the major premise, the other is from the major premise and the conclusion to the minor premise. Therefore, there are 16 kind of mutually-inversistic machine learning models altogether. FOIL, decision tree learning in inductive learning, rough set learning, genetic algorithm, inverse resolution in inductive logic programming are special cases of mutually-inversistic machine learning.

Cicero'sDe Fatoin Deleuze's Logic of Sense

The arguments of the Stoic Chrysippus recorded in Cicero's De Fato are of great importance to Deleuze's conception of events in The Logic of Sense. The purpose of this paper is to explicate these arguments, to which Deleuze's allusions are extremely terse, and to situate them in the context of Deleuze's broader project in that book. Drawing on contemporary scholarship on the Stoics, I show the extent to which Chrysippus' views on compatibilism, hypothetical inference and astrology support Deleuze's claim that the Stoics developed a theory of compatibilities and incompatibilities of events independent of corporeal states of affairs.

ERP Institutionalisation- A Quantitative Data Analysis Using The Integrative Framework of IS Theories

There is a wide agreement that IT projects have disappointing success rates and often generate less value than originally promised. In the context of ERP systems, the same statistical reports exist which demonstrate an overwhelming number of failures in ERP implementations. A thorough review of IS literature, however, leads us to believe that organisations that broadly deploy and routinise IT (in particular, ERPs) into their day-to-day work procedures realise the greatest productivity benefit and business values, and in return perceive to be more successful. The stage wherein ERP is fully assimilated, widely accepted and routinised is also referred to as institutionalised ERP in the extant IS literature of institutional theory. As a result, the authors of this paper believe that studying the influence of various social, environmental, technological and organisational factors on ERP institutionalisation has significant potential in improving the chance of successful ERP projects. In doing so, this paper introduces an integrative framework of IS theories based on an in-depth review of IS literature. The survey instrument is developed to gather data on possible impacts of factors derived from each theory on ERP institutionalisation. The gathered data is then analysed using quantitative data analysis methods to shape the final hypothetical inferences. Finally, based on the data analysis results, this paper proposed valuable suggestions to business and IT managers to improve the chance of ERP success in their organisations.

The compatibility heuristic in non-categorical hypothetical reasoning: Inferences between conditionals and disjunctions

A new theory explains how people make hypothetical inferences from a premise consistent with several alternatives to a conclusion consistent with several alternatives. The key proposal is that people rely on a heuristic that identifies compatible possibilities. It is tested in 7 experiments that examine inferences between conditionals and disjunctions. Participants accepted inferences between conditionals and inclusive disjunctions when a compatible possibility was immediately available, in their binary judgments that a conclusion followed or not (Experiment 1a) and ternary judgments that included it was not possible to know (Experiment 1b). The compatibility effect was amplified when compatible possibilities were more readily available, e.g., for ‘A only if B’ conditionals (Experiment 2). It was eliminated when compatible possibilities were not available, e.g., for ‘if and only if A B’ bi-conditionals and exclusive disjunctions (Experiment 3). The compatibility heuristic occurs even for inferences based on implicit negation e.g., ‘A or B, therefore if C D’ (Experiment 4), and between universals ‘All A’s are B’s’ and disjunctions (Experiment 5a) and universals and conditionals (Experiment 5b). The implications of the results for alternative theories of the cognitive processes underlying hypothetical deductions are discussed.

The Logical Goodness of Abduction in C. S. Peirce's Thought

The term “abduction” has been used with different meanings since its introduction in C. S. Peirce’s writings. It has been used to refer to inference to the best explanation, hypothetical inference, inference to new explanations, and a guessing-instinct. These meanings converge to solve a central problem: how do new ideas emerge in inquiry? Different authors defend different meanings of “abduction” which, in their view, resolve this fundamental problem. This article seeks to displace the central question of abduction in order to account more coherently for its different meanings in Peirce’s thought. It is argued that abduction is not concerned with the emergence of new ideas in reasoning but instead with how ideas are made to fulfill their logical purpose. Since the logical goodness of abduction is most directly treated in Peirce’s 1903 Harvard Lectures on Pragmatism, this article first examines the link between abduction, pragmatism, and logical goodness in those lectures. This initial examination leads us to displace the central question of abduction, from “how do new ideas emerge?” to “how do ideas fulfill their logical purpose?”

Hypothetical and certain inferences from conditional arguments read in texts.

In 3 experiments, affirmative and hypothetical probes were presented after narrative texts containing conditional arguments. According to the data, readers represented modus ponens deductions as certain, except when it was only a weakly necessary cause of a given effect. They represented any logically invalid inferences resulting from affirming the conditional consequent as hypothetical, except when it was the effect of strongly sufficient cause. Accordingly, readers must be processing conditional syntax as an asymmetric constraint. However, the underlying causal knowledge can be sufficient either to discredit or warrant the inferences. Thus according to the theory of natural logic, readers can draw formal deductions and be convinced of their necessity. This provides further evidence that readers can represent their inferences as hypothetical (N. Campion, 2004).

Probabilistic Argumentation Systems and Abduction

Probabilistic argumentation systems are based on assumption-based reasoning for obtaining arguments supporting hypotheses and on probability theory to compute probabilities of supports. Assumption-based reasoning is closely related to hypothetical reasoning or inference through theory formation. The latter approach has well known relations to abduction and default reasoning. In this paper assumption-based reasoning, as an alternative to theory formation aiming at a different goal, will be presented and its use for abduction and model-based diagnostics will be explained. Assumption-based reasoning is well suited for defining a probability structure on top of it. On the base of the relationships between assumption-based reasoning on the one hand and abduction on the other hand, the added value introduced by probability into model based diagnostics will be discussed. Furthermore, the concepts of complete and partial models are introduced with the goal to study the quality of inference procedures. In particular this will be used to compare abductive to possible explanations.

The Development of Modus Ponens in Antiquity : From Aristotle to the 2nd Century AD

Abstract'Aristotelian logic', as it was taught from late antiquity until the 20th century, commonly included a short presentation of the argument forms modus (ponendo) ponens, modus (tollendo) tollens, modus ponendo tollens, and modus tollendo ponens. In late antiquity, arguments of these forms were generally classified as 'hypothetical syllogisms'. However, Aristotle did not discuss such arguments, nor did he call any arguments 'hypothetical syllogisms'. The Stoic indemonstrables resemble the modus ponens/tollens arguments. But the Stoics never called them 'hypothetical syllogisms'; nor did they describe them as ponendo ponens, etc. The tradition of the four argument forms and the classification of the arguments as hypothetical syllogisms hence need some explaining. In this paper, I offer some explanations by tracing the development of certain elements of Aristotle's logic via the early Peripatetics to the logic of later antiquity. I consider the questions: How did the four argument forms arise? Why were there four of them? Why were arguments of these forms called 'hypothetical syllogisms'? On what grounds were they considered valid? I argue that such arguments were neither part of Aristotle's dialectic, nor simply the result of an adoption of elements of Stoic logic, but the outcome of a long, gradual development that begins with Aristotle's logic as preserved in his Topics and Prior Analytics; and that, as a result, we have a Peripatetic logic of hypothetical inferences which is a far cry both from Stoic logic and from classical propositional logic, but which sports a number of interesting characteristics, some of which bear a cunning resemblance to some 20th century theories.

Canonical correspondence analysis for estimating spatial and environmental effects on microsatellite gene diversity in brook charr (Salvelinus fontinalis)

AbstractThe understanding of the relationships between environmental factors and evolutionary forces is of importance to preserve opportunities for the continuation of dynamic evolutionary and ecological processes. This involves the identification and quantification of the relative importance of environmental factors that may influence these processes. Nevertheless, environmental factors are generally interpreted in terms of hypothetical inferences as relationships between environmental and genetic variables are often difficult to quantify. In this study, we used a statistical framework based on canonical correspondence analysis in order to determine the relative contribution of drainage pattern and environmental factors in structuring inter‐ and intrapopulational genetic diversity among brook charr populations as depicted by microsatellite analysis. These procedures simultaneously analyse several sets of variables and determine their relative contribution. The results revealed the influence of drainage pattern, altitude and human‐induced factors on the pattern of genetic diversity and, particularly, the important role of historical events in explaining patterns of contemporary genetic diversity among populations. The statistical framework used in this study provides an efficient way to empirically relate variations of genetic diversity and descriptive variables in general.

Guidelines for Monitoring of Anthracycline Cardiomyopathy: A Rebuttal

The manuscript published in the March issue of Pediatrics by Lipshultz et al1 discusses and challenges the protocol recommended by the Cardiology Committee of the Children's Cancer Study Group2 (CCSG) for cardiac monitoring of patients receiving anthracyclines and modification of therapy based on the results. Lipshultz et al contend that, adopting the published recommendations would be deleterious to patient care. Their discussion, however, is supported by hypothetical inferences and selective quotation of the CCSG article and its references, rather than by data.

MEDUSA: A Fuzzy Expert System for Medical Diagnosis of Acute Abdominal Pain

Even today, the diagnosis of acute abdominal pain represents a serious clinical problem. The medical knowledge in this field is characterized by uncertainty, imprecision and vagueness. This situation lends itself especially to be solved by the application of fuzzy logic. A fuzzy logic-based expert system for diagnostic decision support is presented (MEDUSA). The representation and application of uncertain and imprecise knowledge is realized by fuzzy sets and fuzzy relations. The hybrid concept of the system enables the integration of rule-based, heuristic and case-based reasoning on the basis of imprecise information. The central idea of the integration is to use case-based reasoning for the management of special cases, and rule-based reasoning for the representation of normal cases. The heuristic principle is ideally suited for making uncertain, hypothetical inferences on the basis of fuzzy data and fuzzy relations.
