Correcting Hierarchical Plans by Action Deletion
Authors: Barták Roman , Ondrčková Simona , Behnke Gregor , Bercher Pascal
Published: October 2021

Hierarchical task network (HTN) planning is a model-based approach to planning. The HTN domain model consists of tasks and methods to decompose them into subtasks until obtaining primitive tasks (actions). There are recent methods for verifying if a given action sequence is a valid HTN plan. However, if the plan is invalid, all existing verification methods only say so without explaining why the plan is invalid. In the paper, we propose a method that corrects a given action sequence to form a valid HTN plan by deleting the minimal number of actions. This plan correction explains what is wrong with a given action sequence concerning the HTN domain model.
DEL-based Epistemic Planning for Human-Robot Collaboration: Theory and Implementation
Authors: Bolander Thomas , Dissing Lasse , Herrmann Nicolai
Published: October 2021

Epistemic planning based on Dynamic Epistemic Logic (DEL) allows agents to reason and plan from the perspective of other agents. The framework of DEL-based epistemic planning thereby has the potential to represent significant aspects of Theory of Mind in autonomous robots, and to provide a foundation for human-robot collaboration in which coordination is achieved implicitly through perspective shifts. In this paper, we build on previous work in epistemic planning with implicit coordination. We introduce a new notion of indistinguishability between epistemic states based on bisimulation, and provide a novel partition refinement algorithm for computing unique representatives of sets of indistinguishable states. We provide an algorithm for computing implicitly coordinated plans using these new constructs, embed it in a perceive-plan-act agent loop, and implement it on a robot. The planning algorithm is benchmarked against an existing epistemic planning algorithm, and the robotic implementation is demonstrated on human-robot collaboration scenarios requiring implicit coordination.
Parallelisable Existential Rules: a Story of Pieces
Authors: Buron Maxime , Mugnier Marie-Laure , Thomazo Michaël
Published: October 2021

In this paper, we consider existential rules, an expressive formalism well adapted to the representation of ontological knowledge, as well as data-to-ontology mappings in the context of ontology-based data integration.

The chase is a fundamental tool to do reasoning with existential rules as it computes all the facts entailed by the rules from a database instance. We introduce parallelisable sets of existential rules, for which the chase can be computed in a single breadth-first step from any instance. The question we investigate is the characterization of such rule sets. We show that parallelisable rule sets are exactly those rule sets both bounded for the chase and belonging to a novel class of rules, called pieceful. The pieceful class includes in particular frontier-guarded existential rules and (plain) datalog. We also give another characterization of parallelisable rule sets in terms of rule composition based on rewriting.
The Nondeterministic Situation Calculus
Authors: De Giacomo Giuseppe , Lespérance Yves
Published: October 2021

The standard situation calculus assumes that atomic actions are deterministic. But many domains involve nondeterministic actions, with problems such as fully observable nondeterministic (FOND) planning and high-level program execution requiring solutions. Various approaches have been proposed to accommodate nondeterminism on top of the standard situation calculus language, for instance by introducing nondeterministic programs as in Golog and ConGolog. But a key problem in these approaches is that they don’t clearly distinguish between choices that can be made by the agent and choices that are made by the environment, i.e., angelic vs. devilish nondeterminism. In this paper, we propose a simple extension to the standard situation calculus that accommodates nondeterministic actions and preserves Reiter’s solution to the frame problem and answering projection queries through regression. We also provide a formalization of FOND planning and show how ConGolog high-level program execution in nondeterministic domains can be defined.
Generalized Temporal Inference via Planning
Authors: Aineto Diego , Jimenez Sergio , Onaindia Eva
Published: October 2021

This paper introduces the Temporal Inference Problem (TIP), a general formulation for a family of inference problems that reason about the past, present or future state of some observed agent. A TIP builds on the models of an actor and of an observer. Observations of the actor are gathered at arbitrary times and a TIP encodes hypothesis on unobserved segments of the actor's trajectory. Regarding the last observation as the present time, a TIP enables to hypothesize about the past trajectory, future trajectory or current state of the actor. We use LTL as a language for expressing hypotheses and reduce a TIP to a planning problem which is solved with an off-the-shelf classical planner. The output of the TIP is the most likely hypothesis, the minimal cost trajectory under the assumption that the actor is rational. Our proposal is evaluated on a wide range of TIP instances defined over different planning domains.
Belief Contraction in Non-classical logics as Hyperintensional Belief Change
Authors: Souza Marlo , Wassermann Renata
Published: October 2021

AGM's belief revision is one of the main paradigms in the study of belief change operations. Despite its popularity and importance to the area, it is well recognised that AGM's work relies on a strong idealisation of the agent's capabilities and the nature of beliefs themselves. Particularly, it is recognised in the literature that Belief and Knowledge are hyperintensional attitudes, i.e. they can differentiate between contents that are necessarily equivalent, but to our knowledge, only a few works have explicitly considered how hyperintensionality affects belief change. This work investigates abstract operations of hyperintensional belief change and their connection to belief change in non-classical logics, such as belief contraction operations for Horn Logics and Description Logics. Our work points to hyperintensional belief change as a general framework to unify results in belief change for non-classical logics.
Finitely Materialisable Datalog Programs with Metric Temporal Operators
Authors: Wałęga Przemysław A. , Zawidzki Michał , Cuenca Grau Bernardo
Published: October 2021

DatalogMTL is an extension of Datalog with metric temporal operators that has recently received significant attention. In contrast to plain Datalog, where scalable implementations are often based on materialisation (a.k.a. forward chaining), reasoning algorithms for recursive fragments of DatalogMTL are automata-based and not well suited for practice. In this paper we propose the class of finitely materialisable DatalogMTL programs, for which forward chaining reasoning terminates after finitely many rounds of rule application. We show that, for bounded programs (a large fragment of DatalogMTL where temporal intervals are restricted to not mention infinity), checking whether a program is finitely materialisable is feasible in exponential time, and propose sufficient conditions for finite materialisability that can be checked more efficiently. We finally show that fact entailment over finitely materialisable bounded programs is ExpTime-complete, and hence no harder than Datalog reasoning.
Making DL-Lite Planning Practical
Authors: Borgwardt Stefan , Hoffmann Jörg , Kovtunova Alisa , Steinmetz Marcel
Published: October 2021

Planning in the presence of background ontologies is a topic of long-standing interest in AI. It combines the problems of (1) belief update complexity and (2) state-space combinatorics. DL-Lite offers an attractive solution to (1), with belief updates possible at the ABox level. Indeed, it has been shown that DL-Lite planning can be compiled into the commonly used planning language PDDL. Yet that compilation was previously found to be infeasible for off-the-shelf planning systems. Here we analyze the reasons for this problem and find that the bottleneck lies in the planner pre-processes, in particular in the naïve DNF transformations used to compile the PDDL input into the planners' internal representations. Consequently, we design a PDDL pre-compiler realizing a polynomial DNF transformation. We leverage a particular PDDL language feature ("derived predicates") to avoid the need for excessive control structure. Our pre-compiler turns out to be quite effective: the previous bottleneck disappears, and experiments on a broad range of benchmarks demonstrate the first practical technology for DL-Lite planning.
Measuring Inconsistency over Sequences of Business Rule Cases
Authors: Corea Carl , Thimm Matthias , Delfmann Patrick
Published: October 2021

We investigate inconsistency and culpability measures for multisets of business rule bases. As companies might encounter thousands of rule bases daily, studying not only individual rule bases separately, but rather also their interrelations, becomes necessary. As current works on inconsistency measurement focus on assessing individual rule bases, we therefore present an extension of those works in the domain of business rules management. We show how arbitrary culpability measures (for single rule bases) can be automatically transformed for multisets, propose new rationality postulates for this setting, and investigate the complexity of central aspects regarding multi-rule base inconsistency measurement.

This paper presents an application that we developed to assist users with the creation of an investment profile for the selection of financial assets. It consists of a natural language interface, an automatic translation to a declarative FO(.) knowledge base, and the IDP reasoning engine with multiple forms of logical inference. The application speeds up the investment profile creation process, and reduces the considerable inherent operational risk linked to the creation of investment profiles
Admissibility in Probabilistic Argumentation
Authors: Baier Christel , Diller Martin , Dubslaff Clemens , Gaggl Sarah Alice , Hermanns Holger , Käfer Nikolai
Published: October 2021

Abstract argumentation is a prominent reasoning framework.

It comes with a variety of semantics, and has lately been enhanced by probabilities to enable a quantitative treatment of argumentation.

While admissibility is a fundamental notion in the classical setting, it has been merely reflected so far in the probabilistic setting.

In this paper, we address the quantitative treatment of argumentation based on probabilistic notions of admissibility in a way that they form fully conservative extensions of classical notions.

In particular, our building blocks are not the beliefs regarding single arguments.

Instead we start from the fairly natural idea that whatever argumentation semantics is to be considered, semantics systematically induces constraints on the joint probability distribution on the sets of arguments.

In some cases there might be many such distributions, even infinitely many ones, in other cases there may be one or none.

Standard semantic notions are shown to induce such sets of constraints, and so do their probabilistic extensions.

This allows them to be tackled by SMT solvers, as we demonstrate by a proof-of-concept implementation.

We present a taxonomy of semantic notions, also in relation to published work, together with a running example illustrating our achievements.

STATISTICAL ANALYSIS OF THE INFLUENCE OF EXCHANGE RATE DIFFERENCES ON THE FINANCIAL RISK OF STEVEDORING COMPANIES
Authors:   Odessa National Maritime University, Oneshko Svitlana , Hevrek Yuliia ,   Odessa National Maritime University
Published: October 2021

Increased interest from users of financial information, which is risky in nature, determines the relevance of the study of the impact of exchange rate differences on the financial risk of economic entities and their financial performance. There is the need to refine the impact of exchange rate differences on the financial risk of economic entities in the perspective of sectoral characteristics, also to determine the practical aspect of using methods of statistical analysis and to identify factors influencing the income generated in foreign currency. The study examines the impact of exchange rate differences on financial risk on the example of state stevedoring companies in Ukraine, the peculiarity of which is the settlement in foreign currency which is associated with the formation of chord rates in US dollars. It is concluded that there is a discrepancy between the US dollar exchange rate, which was included in the financial plan of state stevedoring companies, and the actual exchange rate. This fact directly affected the level of income, namely their reduction from the main activity in absolute terms. Determining the structural ratio of the impact of factors of cargo volume and the average income rate per 1 ton of cargo allowed us to establish that throughout the period there was a negative impact of the income rate factor which is formed in dollar terms. From the standpoint of the statistical analysis of the impact of the dollar on the formation of the revenue side of the financial results of state stevedoring companies of Ukraine and the results, it is proposed to take measures to reduce potential financial risks and avoid / minimize financial losses in terms of income loss, namely graphical and statistical methods based on built models, which adequately describe the dynamics of the series to select the best model for constructing forecast data; during the formation of the financial plan of the stevedoring company to take into account trends in exchange rates by conducting a more detailed analysis, for example, the general trend of exchange rates over time by the method of aggregation of intervals, moving average and analytical alignment; to apply the method of hedging future cash flows that depend on currency risks in order to reduce the propensity to risks and uncertainties associated with changes in external economic conditions for exchange rates which will minimize the negative impact and eliminate uncertainty about exchange rates in the future.

In the current conditions of reforming the education sector in Ukraine and the difficult economic situation, the issues of cost optimization, including cost optimization in educational institutions, are becoming relevant. Therefore, the purpose of this article is to consider and identify the main areas of cost optimization in vocational education institutions. The article identifies and describes the main sources of funding for vocational education institutions and emphasizes the need to develop a comprehensive system of cost optimization to ensure the effective functioning of the educational institution. It is determined that the purpose of cost optimization in vocational education institutions is to improve the quality of education and the efficiency of institutions by efficient use of available funds. The main directions of cost optimization in these institutions and the factors that need to be considered to ensure cost optimization are described. Also, three main aspects for the organization of cost optimization, including organizational, functional, and motivational, are identified and analyzed. In addition, a general analysis of the cost management system from the standpoint of a cost-oriented approach is given, highlighted the benefits of such a system, and proposed a scheme of cost optimization in vocational education institutions from the standpoint of cost- oriented approach. It was found that the process of cost optimization in vocational education institutions is complex, diverse and requires consideration of some aspects and factors, as well as improving the current budgeting system, creating a reliable system of control and management decisions, developing and implementing reporting systems of using funds. But with the help of cost optimization it is possible to ensure the competitiveness and stability of the educational institution.

On a variability measure for estimates of parameters in the statistics of interval data
Authors: Шарый С.П.
Published: October 2021

Представлена одна из возможных конструкций количественной меры вариабельности оценки параметров в задаче восстановления линейной зависимости по интервальным данным. Она показывает степень изменчивости и неоднозначности оценки, и необходимость ее введения диктуется тем обстоятельством, что в условиях интервальных данных ответ к задаче, как правило, не является единственным. Дается вывод новой меры вариабельности, и ее применение иллюстрируется на конкретных примерах. В заключение статьи обсуждаются содержательные мотивации и смысл новой величины с точки зрения других известных характеристик данных.

The article presents a possible construction for quantitative variability measure of parameter estimates in the data fitting problem under interval uncertainty. It is designed to show the degree of variability and ambiguity of the estimate. The problem is important since the answer to the data fitting problem may be not unique under the uncertainty of interval data. Otherwise, the problem may have a whole set of such feasible answers, and an estimate of the size of this set can serve as a variability measure of the solution. Socalled maximum compatibility method is considered as a method for evaluating the parameters of the function. An estimate of the parameters is taken as the maximum point of a special recognizing functional, i.e. a certain function that characterizes compatibility of the estimate with interval empirical data. Then the variability measure is simply computed as the product of several values found in the solution of the data fitting problem. These values are maximum of the recognizing functional, minimum of the condition number of the data matrix and the ratio of the norm of the parameter estimate to the norm of the vector of function values. A derivation of the new variability measure is given, and its application is illustrated with specific examples. In conclusion, the article discusses the motivation and interpretation of the new variability measure from the point of view of other known data characteristics.

Evaluation of the structure and characteristics of circumtrindene derivatives: a DFT study
Authors: Kazemi S. , Zabarjad Shiraz N. , Samadizadeh M. , Ezabadi A.
Published: October 2021

The structures and properties of circumtrindene derivatives were studied at M062X/6-31+G(d,p) level of theory. The UV spectra of compounds were simulated by TD DFT methods. The calculated values of λmax (344 nm to 403 nm) were attributed to HOMO to LUMO electronic transitions of compounds. The frontier molecular orbitals have been studied based on NBO calculations and the results were used to estimate the HOMO—LUMO energy gap, ionization potential, electron affinity, electronegativity, electrophilicity index, global hardness, softness, and chemical potential of the compounds. Among the studied derivatives, the structure containing pyridine and furan rings possessed the highest ionization energy (9.007 eV), electron affinity (2.667 eV), electronegativity (5.837 eV), and was the most polar molecule. In addition, compound 7 had the smallest chemical potential (–5.837 eV), polarizability (328.560 a.u.) and the lowest energy levels of HOMO (–8.3672 eV) and LUMO (–3.3062 eV) orbitals. While the derivative having pyrrole rings had the highest softness (0.172 e/V), chemical potential (–4.272 eV), and the greatest λmax (403 nm) in the UV spectrum. In addition, this compound had the lowest hardness (2.912 eV), ionization energy (7.184 eV) and electronegativity (4.272 eV). Also, the aromaticity of individual rings was evaluated by calculating NICS and HOMHED indices. The NICS results showed that the peripheral 6-membered rings represented the best aromatic properties.

Published: October 2021

Teachers have to face many different stressful situations in schools. In this context serious attention has been paid, and much research has been carried out, to investigate the issue of potential stressors occurring in school or class environment. Although pre-service teacher training does not usually include training related to the development of the teachers` competence to solve stressful situations in lessons, as soon as teachers start their teaching career, they are automatically considered to be equipped with this competence. In the research, presented in this paper, the main goal was to identify the most frequent stressors that primary and secondary school teachers face in their everyday teaching. Two methods were used to collect necessary research data: a semi-structured interview with teachers, and observation of teachers during the lessons they taught. Based on the interview data analyses the following nine stressors were identified as the most frequent and most serious (in order): difficult students, mismatch between students’ performance requirements and their abilities, disruptive behavior of students, inadequate student attention, social and emotional factors of the environment in which students live, use of mobile phones during lessons, overwork and fatigue of teachers, insufficient school equipment and lack of teaching aids, conflicts among students. The aim of the observation was to confirm in practice, the types of the stressors identified from the interview data. Analysis of the records from observations, confirmed some of the previously (in interviews) identified stressors and also identified some further stressors.

The article addresses the potential of using social networks in social education and for solving the problems of youth socialization. There is an urgent social need for the harmonious development of the child's personality, including in the Internet environment. At the same time, there is insufficient knowledge about the organization of education in social networks in science. The article identifies the experience of successful interaction between teachers and students on the Internet and ways of organizing event situations in social networks. The study was conducted in February-October 2020 and analysed the content of open official accounts of educational organizations in the social networks ‘VKontakte’, Instagram and documents of educational organizations. The complex use of observation methods, quantitative data processing, expert assessments was aimed at identifying forms of educational activity that are promising for implementation online in social networks. The study showed that, despite the variety of topics and styles, the content of official school accounts resembles a list of news about holidays and other public events. The accounts do not contain materials that could cause vivid emotions and sensations in children, become a source of experiences, value attitudes, experience of interacting with people. Consequently, schools do not provide children with opportunities for self-knowledge, self-determination, self-realization, and do not support their initiatives in social networks. The article recommends that schools expand the practice of organizing networked educational events. For this, they need to create groups of different ages for children and adults for joint planning, organizing, conducting, summing up creative deeds. The maintenance of a thematic Instagram account of a school is offered as an example of a successful subject-subject interaction between a teacher-educator and students in social networks.

Migratory birds are birds that fly or move from their breeding place to their non-breeding location. Migratory birds usually migrate to the southern part of the earth or tropical regions to avoid limited resources during winter in their breeding areas (Bildstein, 2006). Bird of Prey or Raptors are a group of birds that frequently migrate. Raptors carry out-migration in several areas which are commonly referred to as flyways. Indonesia is also part of the flight path for migratory birds (Sukmantoro et al., 2007). At this time there were approximately 17 types of migrant raptors in Indonesia. Research on raptor migration has been carried out for a long time in various regions. In the Yogyakarta area, there have been observations of a migrant raptor, but there are no official publications and research on migrant raptor in the Bukit 76 Kaliurang area, Yogyakarta. Therefore this research was conducted to know about migratory raptor in Yogyakarta. This research was conducted at Bukit 76 Kaliurang, Hargobinangun, Pakem, Yogyakarta. The research was conducted in December 2019-March 2020, July-August 2020, and October-November 2020. This research was conductes through observations in the morning at 07.00-11.00 WIB using birdwatching techniques and purposive methods. The results of this study recorded 1 species of migrant raptor, namely the Oriental Honey-buzzard (Pernis ptilorhynchus) and 2 species of resident raptors, namely the Crested Serpent Eagle (Spilornis cheela) and the Brahminy Kite (Haliastur indus).

The health impact for active and passive smokers is damage to the organs and respiratory tract. The body organs initially experience inflammation which increases the number of white blood cells, one of which is an increase in lymphocytes. One of the efforts to reduce the damage caused free radical by cigarette smoke is by consuming Calcitriol. Objective: To determine the effect of presenting Calcitriol on lymphocyte levels in male Wistar rats (Rattus norvegicus) exposed to cigarette smoke. Methods: This type of research is a pure experimental (true-experiment) using a pre and post-test research design with a control group design to check lymphocyte levels in male Wistar rats (Rattus norvegicus). 24 rats were divided into 6 groups simultaneously. Random, namely the control group 1 (exposed to cigarette smoke and not given Calcitriol), group 2 (exposed to cigarette smoke and not given Calcitriol), placebo control group (exposed to cigarette smoke and given olive oil), treatment 1 (exposed to cigarette smoke and given Calcitriol with a dose of 0.25 µgr / head), treatment 2 (exposed to cigarette smoke and given Calcitriol at a dose of 0.5 µgr / head) and treatment 3 (exposed to cigarette smoke and given Calcitriol at a dose of 1 µgr / head). Results: Paired t-test lymphocyte levels showed evidence that stated (p <0.05) in the K2 group (p = 0.014), the K3 group (p = 0.049), the P1 group (p = 0.012) and the P3 group (0.001) . Meanwhile, group K1 (p = 0.115) and group P2 (p = 0.066) had no statistical difference. Conclusion: Calcitriol administration can reduce lymphocyte levels in male Wistar rats exposed to cigarette smoke.

Cancer is the deadliest health problem after cardiovascular system diseases. New strategies have been developed over the years in the fight against cancer. Silver nanoparticles are one of these approaches. In this study, it was aimed to synthesize silver nanoparticles with the green approach using Elaeagnus angostifolia aqueous extract and to investigate the cytotoxic effects of these nanoparticles. Silver nanoparticles have been characterized by analytical methods such as UV-Vis, FTIR, SEM, EDX. The peak around 3 keV in the EDX spectrum confirms the synthesis of silver nanoparticles. In vitro cytotoxic activity of silver nanoparticles was tested on human prostate cancer cell line PC3, human cervical cancer cell line HELA and normal mouse fibroblast cell line L929. It has been found that silver nanoparticles synthesized with the aqueous extract of Elaeagnus angustifolia showed a dose-dependent cytotoxic effect on HELA and PC3 cells.
