Published: November 2022

Xylanase is an extracellular enzyme capable of hydrolyzing hemicellulose so that it can convert xylan into xylose. Xylanase enzymes can be used in the pulp and paper industry. This study aims to determine the effect of temperature, pH on enzyme production by immobilized thermophilic bacteria using rice straw xylan extract as a substrate and to see the effect of xylanase administration on the whiteness level of inked paper waste. This study was an experimental study and used a completely randomized design (CRD). Enzyme activity was measured using a spectrophotometer at a wavelength of 540 nm. Enzyme activity data were analyzed using the ANOVA test and continued with the DMRT (Duncan Multiple Range Test) further test with a level of 5% and the whiteness of the paper was determined by testing the kappa number. The results obtained were that the temperature of immobilize thermophilic bacteria using rice straw xylan extract as a substrate affected the xylanase enzyme activity with an optimum temperature of 75°C having the highest average value of enzyme activity 4.668 U/mL. Meanwhile, the optimum pH for immobilized thermophilic bacteria to produce xylanase was pH 8.5 with the highest average value of enzyme activity 4.854 U/mL. The addition of xylanase enzyme in the fermentation process of inked paper waste was able to increase the brightness of the inked paper with a lower average value of kappa number of 2.762 compared to the higher control of 5.525.

Published: November 2022

The Covid-19 pandemic affects almost all aspects of life, including the education aspect. To break the chain of the spread of the Covid-19 pandemic, the learning system that was originally offline switched to online learning. Online learning makes students bored quickly and students perceive physics as a difficult subject. In addition, the current swift currents of globalization have caused the erosion of cultural values. Therefore, there is a need for media that can restore  cultural values, especially Minangkabau culture in students' lives. This study aims to produce an android-based supporting learning media about circular motion material for high school students in class X. This application is contextual and integrated with Minangkabau culture so that students will be more interested in studying physics. The method used in this study is the Four D research and development (RND) method which consists of Define, Design, Develop, and Dessiminate. The resulting application is one of the contributions in the development of learning media, which is expected to be one of the appropriate Physics learning solutions in the current pandemic era.

This research is motivated by the lack of use of interactive, interesting and fun media for students, especially on technology-based media and during the learning process students have not been actively involved and are less involved in the process of using media. Technology-based learning media has not yet been developed because teachers only rely on theme books, MRT books, and other supporting books as sources as well as learning media, occasionally the teacher shows videos from YouTube. This study aims to determine the development of interactive multimedia in integrated thematic learning using Macromedia Flash in grade IV Elementary School in Padang City which is valid and practical.

This type of research is Research and development (R&D). The development model used in this study is the ADDIE model with the Analysis stage, the Design stage, the Development stage, the Implementation stage and the Evaluation stage.

The results of the research developed, obtained the results of the validity level of learning media in integrated thematic learning with a total validation value of 86.4% in the very valid category. Furthermore, the results of practical trials of learning media in the form of interactive multimedia using Macromedia Flash in integrated thematic learning are stated to be very practical. This can be seen from the teacher's response and the student's response. Where the teacher response questionnaire scored 95% in the very practical category and 15 student response questionnaires scored 94.1% in the very practical category. Thus, the development of learning media in the form of interactive multimedia using Macromedia Flash in integrated thematic learning in grade IV Elementary School is very valid and very practical.

Published: November 2022

Marine fish farm industries face ongoing challenges due to a lack of quality seed, a low survival rate and a slow growth rate of marine fish larvae. One of the most sensitive problems is a nutritionally balanced quality feed for rearing these larval fish at the first feeding stage. Many studies have reported high requirements of n-3 highly unsaturated fatty acids, mainly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) for proper development, which have also been reported to increase the survival and growth status of larval fish. Marine fish larvae have difficulties accepting artificial feed at their weaning stage, so live food plays a vital role in the rearing process. Artemia is one of the most commonly used live food organisms in marine fish larvae production systems. However, they are deficient in EPA and DHA, which are most critical for larval development. Recent advancements in live food production systems have developed several techniques of bio-encapsulation and enrichment of nutrients in live food. But the instability of DHA and the high cost of enrichment procedures remain-bottlenecks for supplying proper nutrients through live food. This short review emphasizes challenges in marine fish larvae culture in terms of HUFAs nutrition with a comparative study on DHA requirements of marine larval fish and its availability in live food organism Artemia. We also highlighted several factors affecting DHA enrichment process and its degradation following enrichment procedures.

Happy Readers. The Literary Magazine as a Lifestyle Coach

In contemporary popular literary culture (Collins 2010), the circulation of representations of reading as a kind of lifestyle is increasing rapidly. I will highlight this phenomenon by way of a discussion of two new literary magazines, the Swedish Books & Dreams, and the British The Happy Reader. Here, reading becomes a lifestyle fully imbedded in contemporary ”designer culture” (Julier 2013), and is metonymically linked to, amongst other things, interior design, cooking, and travel. Which reading practices are encouraged in the magazines, and in what ways do they challenge (or confirm) traditional ideas of the forms, functions, and values of reading?Keywords: , , ,

Words, things

This article explores the concepts of language and discourse as these terms appear in Michel Foucault’s early work, and relates these concepts to contemporary theological discussions of knowledge. Further, it describes how Foucault’s discursive approach to knowledge emerges out of his notion of language – which, in turn, is inspired by authors including Jorge Luis Borges, Georges Bataille and Maurice Blanchot. It illustrates how Foucault’s conception of language approaches a material account that problematizes the notion of words as things, and how this trait is intensified in the transition from the concept of language to the concept of discourse in his work. Finally, the article reflects upon the theological implications of Foucault’s discursive approach to knowledge as it appears in his analysis of Gustave Flaubert. The theological reflection is performed in dialogue with contemporary theology, here represented by John D. Caputo, Daniel Colucciello Barber and Jeffrey Robbins.
Michel Foucault, leser av Oidipous Turannos
Authors: Eliassen Knut Ove

Michel Foucault as Reader of Oidipous Tyrannos

This article gives an overview of Michel Foucault’s various engagements with Sophocles’ tragedy over a period of fifteen years, and the six lectures that are currently available. The ambition is to show how Foucault’s work on the Greek drama is less an exercise in classical scholarship (and the story of its progress) than a series of test-cases for Foucault’s shifting theoretical and political interests. Hence, in various ways, the three lectures from the early seventies approach Sophocles from an explicitly Nietzschean perspective, particularly highlighting the power-knowledge economy at stake in what Foucault regards (drawing on Jean-Pierre Vernant) first and foremost as a political drama about the foundation and transition of political power. While sharing many of the analytical insights from Foucault’s earlier work, the three lectures from the early eighties discard the power-knowledge-matrix as an analytical tool, focusing instead on the various procedures for truth-production in the drama, and the different and conflicting forms of veridiction (truth-telling). Rather than focus on the potential philological merits of Foucault’s lectures, driven as they are by his methodological and philosophical concerns, this article emphasizes how any engagement with Antiquity is necessarily embedded in the politics and polemics of the present. Accordingly, this article finds that Foucault’s re-readings of Oidipous Tyrannos come across as attempts to identify present-day concerns; they should thus be regarded as that which Foucault terms “contributions to a critical ontology of ourselves.”

”To whom am I shouting? Who listens?”: Voice and Ethics in Svetlana Alexievich’s Zinkyboys

Few authors have engaged so intensively with the human voice as Svetlana Alexievich. In her interview books, the monologues of testimony run over hundreds of pages, completely dominating the narration. In Zinkyboys (1998) the technique of the interview-book attains perhaps its fullest realization: the interviewees’ speech seems to operate freely in quotations, without authorial comments, confirmations, or denials. But how shall we understand this ”pure” documentary voice? This article proposes a few basic theoretical starting points for the analysis of the production of voice and address in documentary literature, and aims to demonstrate how these aspects interact with textual ethics in Alexievich’s text. My perspective on documentary literature emphasizes performative and dialogical aspects, rather than questions of representation and fact-fiction dichotomies (formerly dominant focal-points of research on documentary literature). Utilizing a method that combines speech act theory and narratology, with philosophical thoughts on language and ethics presented by Emmanuel Levinas, the genealogy of the documentary voice may be discerned. Most important is how the documentary text proves to work on double grounds in the production of speech acts – utterances in the real situation/event (which precede the text) negotiate with an overall form of address that the literary work connotes. Zinkyboys and its quotations manifest the performative of ”the saying” in a way that corresponds to an ethical responsibility in the text. As an illustrative example, this article analyses Alexievich’s frequent use of the ellipsis (three dots), a strategy that, in this documentary context, constitutes what might be termed a ”principle of amplification”.
Cyborgförfattarskapets längre historia

The Extended History of Cyborg Authorship

During the early 1980s, computer programmer William Chamberlain constructed a computer program for textual interplay, called Racter. According to Chamberlain, this purportedly self-learning computer program later produced, through its textual output, a prosaic-poetic work which was eventually published as a printed book in 1984. This work was entitled The Policeman’s Beard Is Half Constructed, and credited Racter as its sole author. The present article presents a reading of this work, in light of historically prominent modes of literary production similar to, but also prior to, computerized text-generation, thus suggesting a longer history of cyborg authorship than has previously been acknowledged. To this end, this article references various examples of mechanized text production and writing procedures, such as William Burroughs’ cut-up technique, as well as Friedrich Kittler’s notion of the poetics of typewriting. Following Espen Aarseth’s conception of cybertext, The Policeman’s Beard is thus regarded as a novel example of a pre-existing, two-sided relation of the influence of writing material to literary style. Further, the more recently developed figure of the cyborg, popularly regarded as the epitome of human-machine symbiosis and transcendence, is rendered visible in the narrative of this book through an emerging intelligence within the story of The Policeman’s Beard. This thematically-oriented process of cognitive growth succeeds, rather than reflects, the formal self-transformation of the code inherent in the program through which the text is produced, supporting my working thesis on the mechanical organization of the text’s capacity of further informing its content. Thus, the following examination of the literary potency of the variable text generator and self-programmable computer software presents a perspective on Racter as an aetheticization of the characterics attributed to the early computer age, with special reference to cybernetic- and artificial intelligence research.
Opportunities for the European Union to Strengthen Biosecurity in Africa
Authors: Wakefield Benjamin
Published: November 2022

The European Union (EU) has a long history of commitment to improving biological security and supporting multilateral approaches to arms controls and non-proliferation. It has supported various biosecurity programmes in recent years and continues to increase its financial support towards these, with a focus on the universalization of the Biological and Toxins Weapons Convention and United Nations Security Council Resolution 1540. More recently, through Council Decision 2021/2072/ CFSP, the EU has committed even further to strengthening biosafety and biosecurity capabilities in Africa, with more meaningful collaboration and an increase in the local and regional ownership of projects. This provides an opportunity for the EU to continue to broaden its approach and improve coordination with international partners. In particular focus is the newly formed European Health Emergency Preparedness and Response Authority (HERA), as it develops its international activities. However, there is still a demonstrated need to strengthen biosecurity-related capacities and capabilities across Africa. This paper highlights the significant opportunities for EU engagement and coordination with international initiatives, such as the Africa Centres for Disease Control and Prevention (Africa CDC) Biosafety and Biosecurity Initiative (BBI) 2021–2025 Strategic Plan and the Global Partnership Signature Initiative to Mitigate Biological Threats in Africa.

Тувинские землетрясения 27.12.2011 (Ms = 6,7) и 26.02.2012 (Мs = 6,8) произошли в зоне Каахемского глубинного разлома, представляю- щего собой одну из крупнейших сейсмогенерирующих структур Алтае-Саянского сейсмоактивного региона. Получены представления о сейсмотектонической позиции очагов и их сейсмической истории на протяжении последних тысячелетий. Важность полученных результатов обусловлена тем, что эти землетрясения являются сильнейшими за всю историю сейсмологических наблюдений в Туве и, таким образом, являются первыми хорошо изученными сильными землетрясениями этого региона. Полученные данные показыва- ют, что сейсмические активизации (кластеры землетрясений) могут представлять собой одно сильнейшее для всей Каахемской зоны сейсмическое событие с Mw = 7,0‑7,5 и несколько с Mw = 6,5‑7,0 по соседним сегментам. Межкластерная повторяемость сейсмических активизаций – примерно раз в тысячу лет. Более слабые события, подобные Тувинским 2011‑2012 гг., за последнее тысячелетие по- вторялись раз в 300‑500 лет, что дает внутрикластерную повторяемость для событий умеренной силы. Получена фундаментальная сейсмотектоническая база для проведения детального сейсмического районирования (ДСР) Республики Тыва, включающая региональ- ные закономерности затухания сейсмических эффектов и повторяемости сильных землетрясений для характерных сейсмотектони- ческих обстановок – сейсмотектонических узлов и магистральных очагов.

Published: November 2022

Student engagement in higher education has been studied from various perspectives, but few studies have compared teachers’ and students’ perspectives on the subject. Considering that student engagement may be reduced to a performativity scarcely related to learning outcomes and that a good deal of it may be invisible to teachers, further studies are needed to contrast teachers’ and students’ views of student engagement in higher education. This article presents the results of a quantitative study about definitions and indicators of student engagement carried out with 118 students and 45 teachers of Law, Education and Nursing from two Catalan public universities (Spain). The results confirm the performativity associated with the concept by both teachers and students, and reveal that students may appreciate silent and invisible engagement more than teachers. The results also show that teachers may conflate signs of student engagement with good academic results and learning, risking an oversimplification of both student engagement and learning.

The primary goal of this paper is to promote the use of gamification as a teaching tool in English language teaching and learning by emphasizing its worth and that gamified lessons can be utilized as a significant didactic tool by teachers to accomplish many learning objectives, including introducing, reviewing, and evaluating didactic topics while simultaneously raising students' motivation, focus, and learning autonomy. This qualitative case study investigated how non-technological gamified lessons enhanced English language learning in a Lithuanian English as a Second Language (ESL) classroom. Non-technology gamification is an understudied area but has the potential to offer valuable insights into English language learning. Qualitative data were collected from interviews and unstructured observations to identify participants' positive and negative experiences. The emerging themes were identified based on Self-Determination Theory (SDT). However, certain challenges were noted during activities that involved touching another participant, unhappy with the materials used and blurred learning outcomes were identified. The unstructured observations indicated that the participants were making attempts to speak in English, engaged and motivated during the activities and were involved in teamwork. The study makes a relevant contribution to scholarship by showing the positive potential of non-technological gamification in English language learning particularly in listening, speaking, reading, and writing skills. Based on the findings, the study provides certain pedagogical implications to encourage teachers to integrate gamified lessons into their pedagogical practices.

Published: November 2022

The features of X-ray semiotics in pneumonia in newborns were evaluated depending on the gestational age at birth. Conducted clinical and radiological examination of newborns with pneumonia. Plain chest radiography was used from radiographic methods. In the group of full-term newborns without signs of intrauterine growth retardation with pneumonia, changes prevailed that were mainly characteristic of the I degree of severity of the respiratory distress syndrome, namely, miliary spotting, limited low-intensity inhomogeneous darkening, blurry nodose-reticular mesh, and a distinguishable "air bronchogram". In full-term newborns with signs of intrauterine growth retardation, changes characteristic of I and II degrees of severity of the respiratory distress syndrome prevailed in equal proportions, that is, a decrease in pneumatization, coarse randomly scattered areas of lung tissue compaction and "air bronchograms". In preterm newborns, depending on the depth of prematurity, and possibly due to a short-term clinically asymptomatic onset, in most cases, II and III degrees of severity of the respiratory distress syndrome were noted at admission: a pronounced decrease in pneumatization (“frosted glass”), smoothing of the pulmonary-diaphragmatic and pulmonary -cardiac border (positive "silhouette" symptom), air bronchograms. The distribution of children according to clinical and radiological signs depends on gestational age, and atelectatic pneumonia is most often recorded in premature babies against the background of morphofunctional immaturity of the lungs. The deeper the prematurity, the more pronounced the influence of immature lung tissue on the occurrence and course of the inflammatory process in the lungs, and the inflammatory process becomes rapid, spreading to a large area of ​​the lungs.

The C++ class library C-XSC for scientific computing has been extended with the possibility to compute scalar products with selectable accuracy in version 2.3.0. In previous versions, scalar products have always been computed exactly with the help of the so-called long accumulator. Additionally, optimized floating point computation of matrix and vector operations using BLAS-routines are added in C-XSC version 2.4.0. In this article the algorithms used and their implementations, as well as some potential pitfalls in the compilation, are described in more detail. Additionally, the theoretical background of the employed DotK algorithm and the necessary modifications of the concrete implementation in C-XSC are briefly explained. Run-time tests and numerical examples are presented as well.

Authors: Zanev Vladimir , Radenski Atanas
Published: November 2022

This paper analyzes difficulties with the introduction of object-oriented concepts in introductory computing education and then proposes a two-language, two-paradigm curriculum model that alleviates such difficulties. Our two-language, two-paradigm curriculum model begins with teaching imperative programming using Python programming language, continues with teaching object-oriented computing using Java, and concludes with teaching object-oriented data structures with Java.
Extending Object-Oriented Network Protocols via alternative Transportation Bindings (Web Services over XMPP)
Authors: Irintchev Mihail D.
Published: November 2022

Distributed and/or composite web applications are driven by intercommunication via web services, which employ application-level protocols, such as SOAP. However, these protocols usually rely on the classic HTTP for transportation. HTTP is quite efficient for what it does — delivering web page content, but has never been intended to carry complex web service oriented communication. Today there exist modern protocols that are much better fit for the job. Such a candidate is XMPP. It is an XML-based, asynchronous, open protocol that has built-in security and authentication mechanisms and utilizes a network of federated servers. Sophisticated asynchronous multi-party communication patterns can be established, effectively aiding web service developers. This paper’s purpose is to prove by facts, comparisons, and practical examples that XMPP is not only better suited than HTTP to serve as middleware for web service protocols, but can also contribute to the overall development state of web services.
Fast Information Retrieval in the Open Grid Service Architecture
Authors: Berka Tobias , Vajteršic Marian
Published: November 2022

In research, grid computing is an established way of providing computer resources for information retrieval. However, e-science grids also contain, process and produce documents - thereby acting as digital libraries and requiring means for information discovery. In this paper, we discuss how distributed information retrieval can be integrated into the Open Grid Service Architecture (OGSA) to efficiently provide image retrieval for e-science grids. We identify two fundamental ways of performing information retrieval on the grid - as a batch job or as a distributed activity - and argue the case for the latter for reasons of efficiency. We give an analysis of the theoretic communication and computation complexity and demonstrate that bandwidth limitations provide a decisive argument to support our case. We describe further design decisions for our system architecture and give a brief comparison with other designs reported in literature. Lastly, we describe how the statelessness and isolation of web services impede data-intensive, distributed, cross-site activities in OGSA grids, and how to escape them.
An Electromagnetism Metaheuristic for the Uncapacitated Multiple Allocation Hub Location Problem
Authors: Filipović Vladimir
Published: November 2022

In this article, the results achieved by applying an electromagnetism (EM) inspired metaheuristic to the uncapacitated multiple allocation hub location problem (UMAHLP) are discussed. An appropriate objective function which natively conform with the problem, 1-swap local search and scaling technique conduce to good overall performance.Computational tests demonstrate the reliability of this method, since the EM-inspired metaheuristic reaches all optimal/best known solutions for UMAHLP, except one, in a reasonable time.
Interactive 3D Visualization of Bézier Curves using Java Open Graphics Library (JOGL)
Authors: Vlachkova Krassimira , Boikova Marina
Published: November 2022

We present a new program tool for interactive 3D visualization of some fundamental algorithms for representation and manipulation of Bézier curves. The program tool has an option for demonstration of one of their most important applications - in graphic design for creating letters by means of cubic Bézier curves. We use Java applet and JOGL as our main visualization techniques. This choice ensures the platform independency of the created applet and contributes to the realistic 3D visualization. The applet provides basic knowledge on the Bézier curves and is appropriate for illustrative and educational purposes. Experimental results are included.
A Framework for Design-Time Testing of Service-Based Applications at BPEL Level
Authors: Ilieva Sylvia , Pavlov Valentin , Manova Ilina , Manova Denitsa
Published: November 2022

Software applications created on top of the service-oriented architecture (SOA) are increasingly popular but testing them remains a challenge. In this paper a framework named TASSA for testing the functional and non-functional behaviour of service-based applications is presented. The paper focuses on the concept of design time testing, the corresponding testing approach and architectural integration of the consisting TASSA tools. The individual TASSA tools with sample validation scenarios were already presented with a general view of their relation. This paper’s contribution is the structured testing approach, based on the integral use of the tools and their architectural integration. The framework is based on SOA principles and is composable depending on user requirements.

Weighted ICP Algorithm for Alignment of Stars from Scanned Astronomical Photographic Plates
Authors: Marinov Alexander , Zlateva Nadezhda , Dimov Dimo , Marinov Delian
Published: November 2022

Given the coarse celestial coordinates of the centre of a plate scan and the field of view, we are looking for a mapping between the stars extracted from the image and the stars from a catalogue, where the stars from both sources are represented by their stellar magnitudes and coordinates, relatively to the image centre. In a previous work we demonstrated the application of Iterative Closest Point (ICP) algorithm for the alignment problem where stars were represented only by their geometrical coordinates. ICP leads to translation and rotation of the initial points - a correction required for one set of stars to fit over the other. This paper extends the previous work by demonstrating significant improvement of ICP by using the stellar magnitudes as point weights. The improvement consists of great decrease of the iteration count until convergence, which helps in the case of highly “misaligned” initial states. The essential aspects of the ICP method like noise tolerance of false or missing stars are still in charge.
Application of Wavelet Decomposition to Document Line Segmentation
Authors: Laskov Lasko
Published: November 2022

In this paper an approach to document line segmentation is presented. The algorithm is based on a wavelet transform of the horizontal projective profile of the document image. The projective profile is examined as a one-dimensional discrete signal which is decomposed using the pyramidal wavelet algorithm up to a precise scale, where local minima and maxima are discovered. These local extrema, projected into the input signal, correspond to the spacing between document lines and to the pivots of the lines. The method has been tested on a broad set of printed and handwritten documents and proven to be stable and efficient.
A New Method for Computing the Eccentric Connectivity Index of Fullerenes
Authors: Ghorbani Modjtaba , Malekjani Khadijeh
Published: November 2022

The eccentric connectivity index of the molecular graph G, ξ^c (G), was proposed by Sharma, Goswami and Madan. It is defined as ξ^c (G) = Σu∈V(G)degG(u) ecc(u), where degG(x) denotes the degree of the vertex x in G and ecc(u) = Max{d(x, u) | x ∈ V (G)}. In this paper this graph invariant is computed for an infinite class of fullerenes by means of group action.
Variable Neighborhood Search for the File Transfer Scheduling Problem
Authors: Dražić Zorica
Published: November 2022

In this paper a file transfer scheduling problem is considered. This problem is known to be NP-hard, and thus provides a challenging area for metaheuristics. A variable neighborhood search algorithm is designed for the transfer scheduling of files between various nodes of a network, by which the overall transfer times are to be minimized. Optimality of VNS solutions on smaller size instances has been verified by total enumeration. For several larger instances optimality follows from reaching the elementary lower bound of a problem.

Mapping and Merging of Anatomical Ontologies
Authors: Petrov Peter
Published: November 2022

The problem of mapping and merging ontologies in general is an important one in the area of ontology engineering. The same problem considered within the narrower area of anatomical ontologies (AOs) is important in bioinformatics because solving it could enable the transfer of data and the application of knowledge obtained from various model organisms toother model and non-model organisms, and even to research areas such as those of human health and medicine. This paper presents a detailed summary of the author’s PhD researchdone in the period 2007–2013. The paper’s main topic is the problem of mapping and merging of multiple species-specific AOs and the related approaches, methods, and procedures that can be used for solving it.ACM Computing Classification System (1998): J.3, E.1, G.2.2, G.2.3, I.2.1, I.2.4.
On Optimal Quadratic Lagrange Interpolation: Extremal Node Systems with Minimal Lebesgue Constant via Symbolic Computation
Authors: Rack Heinz-Joachim , Vajda Robert
Published: November 2022

We consider optimal Lagrange interpolation with polynomials of degree at most two on the unit interval [−1, 1]. In a largely unknown paper, Schurer (1974, Stud. Sci. Math. Hung. 9, 77-79) has analytically described the infinitely many zero-symmetric and zero-asymmetric extremal node systems −1 ≤ x1 < x2 < x3 ≤ 1 which all lead to the minimal Lebesgue constant 1.25 that had already been determined by Bernstein (1931, Izv. Akad. Nauk SSSR 7, 1025-1050). As Schurer’s proof is not given in full detail, we formally verify it by providing two new and sound proofs of his theorem with the aid of symbolic computation using quantifier elimination. Additionally, we provide an alternative, but equivalent, parameterized description of the extremal node systems for quadratic Lagrange interpolation which seems to be novel. It is our purpose to bring the computer-assisted solution of the first nontrivial case of optimal Lagrange interpolation to wider attention and to stimulate research of the higher-degree cases. This is why our style of writing is expository.
