Abstract:

The simplex method is a very useful method to solve linear programming problems. It gives us a systematic way of examining the vertices of the feasible region to determine the optimal value of the objective function. It is executed by performing elementary row operations on a matrix that we call the simplex tableau. It is an iterative method that by repeated use gives us the solution to any n variable linear programming model. In this paper, we apply the change of basis to construct following simplex tableaus without applying elementary row operations on the initial simplex tableau.

Abstract:

The method of synthetic tableaux is a cut-based tableau system with synthesizing rules introducing complex formulas. In this paper, we present the method of synthetic tableaux for Classical First-Order Logic, and we propose a strategy of extending the system to first-order theories axiomatized by universal axioms. The strategy was inspired by the works of Negri and von Plato. We illustrate the strategy with two examples: synthetic tableaux systems for identity and for partial order.

Abstract:

Introduction: The Robinson — Schensted — Knuth (RSK) algorithm transforms a sequence of elements of a linearly ordered set into a pair of Young tableaux P, Q of the same shape. This transformation is based on the process of bumping and inserting elements in tableau P according to special rules. The trajectory formed by all the boxes of the tableau P shifted in the RSK algorithm is called the bumping route. D. Romik and P. Śniady in 2016 obtained an explicit formula for the limit shape of the bumping route, which is determined by its first element. However, the rate of convergence of the bumping routes to the limit shape has not been previously investigated either theoretically or by numerical experiments. Purpose: Carrying out computer experiments to study the dynamics of the bumping routes produced by the RSK algorithm on Young tableaux as their sizes increase. Calculation of statistical means and variances of deviations of bumping routes from their limit shapes in the L2 metric for various values fed to the input of the RSK algorithm. Results: A series of computer experiments have been carried out on Young tableaux, consisting of up to 10 million boxes. We used 300 tableaux of each size. Different input values (0.1, 0.3, 0.5, 0.7, 0.9) were added to each such tableau using the RSK algorithm, and the deviations of the bumping routes built from these values from the corresponding limit shapes were calculated. The graphs of the statistical mean values and variances of these deviations were produced. It is noticed that the deviations decrease in proportion to the fourth root of the tableau size n. An approximation of the dependence of the mean values of deviations on n was obtained using the least squares method.

Abstract:

Purpose The purpose of the paper is to provide a detailed account of pre-service teachers’ viewpoints on the use of tableaux as pedagogy to analyse short stories in secondary schools based on their exposure to the use of tableaux and their active participation in the process of tableau creation. Design/methodology/approach The study adopted a qualitative approach and a phenomenological design as it provides a detailed account of PGCE English Methodology pre-service teachers’ views on the use of tableaux to teach a short story. The data collection method used was written narratives based on the participants’ detailed accounts of their learning during the process of tableau creation and their viewpoints on the use of such an approach in the teaching of literature within secondary school contexts. The “rich, thick data” extracted from the written narratives were analysed thematically. Findings The findings indicated that although pre-service teachers were initially sceptical towards the use of tableaux as a strategy to teach a short story, as they grew in their understanding of the practices involved their insights into the themes, motifs and characters’ emotional, personal and psychological states of being were enhanced. Originality/value Research in the use of tableaux as a strategy for pre-service teachers to critically analyse and engage with short stories is a novel approach to teaching and limited research has been conducted in the field.

Abstract:

Web ontologies can contain vague concepts, which means the knowledge about them is imprecise and then query answering will not possible due to the open world assumption. A concept description can be very exact (crisp concept) or exact (fuzzy concept) if its knowledge is complete, otherwise it is inexact (vague concept) if its knowledge is incomplete. In this paper, we propose a method based on the rough set theory for reasoning on vague ontologies. With this method, the detection of vague concepts will insert into the original ontology new rough vague concepts where their description is defined on approximation spaces to be used by extended Tableau algorithm for automatic reasoning. A prototype of Tableau's extended algorithm is developed and tested on examples where encouraging results are given by this method to demonstrate that unlike other methods, it is possible to answer queries even in the presence of incomplete information.

Abstract:

AbstractWe provide infinitary proof theories for three common semantic theories of truth: strong Kleene, van Fraassen supervaluation and Cantini supervaluation. The value of these systems is that they provide an easy method of proving simple facts about semantic theories. Moreover we shall show that they also give us a simpler understanding of the computational complexity of these definitions and provide a direct proof that the closure ordinal for Kripke’s definition is $\omega _1^{CK}$. This work can be understood as an effort to provide a proof-theoretic counterpart to Welch’s game-theoretic (Welch, 2009).

Abstract:

Regional Income and Expenditure Budget (APBD) is a very important thing in the progress of a region. APBD is an indicator of public welfare level in a region. Data of APBD that is shared on the official website data.go.id is still hard to read and understood, and for that reason the author will compare the budget value of APBD in every province, district, and city by using visualization. The method the author used is Visual Data Mining by creating an APBD visualization dashboard according to provinces, districts, and cities. Tableau Software is used to create the dashboard because Tableau allows an interactive, easy-to-use dashboard for analyzing lots of data. Besides, Tableau is already supported by many platform such as web based, iPhone app, also Android app, and this application is one of the common for visualization so there are a lot of sources to get more information and to develop visualization. The result of this research could help the government in reevaluating the APBD financial budget in every region in Indonesia. This research can help the people to know the APBD budget applied in every region. Index Terms-Regional Income and Expenditure Budget (APBD), financial, visualization.

Abstract:

This study aims to determine the dominant chemical elements that may improve the monitoring of the productivity and efficiency of heavy engines in 2015-2021 in the company. The method used is usually Scheduled Oil Sampling. This article proposes a new approach. The research problems are analyzing the recorded chemical elements that are produced by heavy engines and visualizing them through the Tableau program. The basic design of the study is learning the given data after visualization and using the Principal Component Analysis. This method is to obtain chemical elements that affect engine wear during each engine's use in the 2015-2021 period. Because there are three categories in each element in the oil sample, namely wear metals, contaminants, and oil additives, a technique is needed to obtain these elements using Principal Component Analysis. Therefore, Oil Sampling Analysis through data exploration using Tableau resulted in a new approach to data analysis of elements recorded by heavy vehicles. The main findings as a result of the analysis are given by the visualization of Tableau, in which there are five machines analyzed to obtain the main components that cause engine wear. From the visualization results, it is shown that there is one engine coded MSD 012 that experienced wear and tear in 2018 and 2019. This shows where two main components, Ca and Mg, dominate engine wear. These results have been confirmed with the related companies. The company then carried out further studies on the machine to get special treatment because of these results.

Abstract:

This paper presents a method for implementing tableau algorithm for description logics (DLs). The architectures of the present DL reasoners such as RACER or FaCT were developed using programming languages as Java or LISP. The implementations are not based on original definition of the abstract syntax, but they require transformation of abstract syntax into concrete syntax implementation languages use. In order to address these issues, we propose the use of model-driven engineering principles for the development of a DL reasoner where a definition of a DL abstract syntax is provided by means of metamodels. The presented approach is based on the use of a MOF-based model repository and QVT-like transformations, which transform models compliant to the DL metamodel taken from the OMG's Ontology Definition Metamodel specification into models compliant to the Tableau metamodel defined in this paper. .

Abstract:

The primary purpose of the research is the improvement of the orders picking process without additional investments for the software, employees, tool and inventories. For problem-solving, the data about picking is exported and preprocessed from WMS. The BigData analysis and product clustering in Tableau software is delivered using the data, where the Product Allocation Problem (PAP) is solved. Picking time for reference scenario and new analysed one is calculated and compared. The presented research proves that standard data collected by WMS could be used for solving PAP for the reduction of total picking time. The method delivered by authors could be in a typical warehouse, where forklifts and employees do the order picking process. The plan after an upgrade could be used for automatic picking, and implemented WMS. For BigData analysis, Tableau is connected to WMS database. Such solution could be used for everyday analysis and planning the allocation of products. The presented method is easy to use; there is no need to invest in expensive software and automation of the picking process to achieve the high performance of the orders picking process. However, its application allows the increase of efficiency rates. Storekeepers can select more products at the same time. The presented research is original because of using simple methods and analysis of specific data, which until now are only used to calculate employee performance indicators.

Abstract:

This paper discusses about how to build a data warehouse (DW) in business intelligence (BI) for a typical marketing division in a university. This study uses a descriptive method that attempts to describe the object or subject under study as it is, with the aim of systematically describing the facts and characteristics of the object under study precisely. In the elaboration of the methodology, there are four phases that include the identification and source data collection phase, the analysis phase, the design phase, and then the results phase of each detail in accordance with the nine steps of Kimball’s data warehouse and the Pentaho Data Integration (PDI). The result is a tableau as a tool of BI that does not have complete ETL tools. So, the process approach in combining PDI and DW as a data source certainly makes a tableau as a BI tool more useful in presenting data thus minimizing the time needed to obtain strategic data from 2-3 weeks to 77 minutes.

Abstract:

Abstract Motivation Elementary flux modes (EFMs) are a key tool for analyzing genome-scale metabolic networks, and several methods have been proposed to compute them. Among them, those based on solving linear programming (LP) problems are known to be very efficient if the main interest lies in computing large enough sets of EFMs. Results Here, we propose a new method called EFM-Ta that boosts the efficiency rate by analyzing the information provided by the LP solver. We base our method on a further study of the final tableau of the simplex method. By performing additional elementary steps and avoiding trivial solutions consisting of two cycles, we obtain many more EFMs for each LP problem posed, improving the efficiency rate of previously proposed methods by more than one order of magnitude.

Abstract:

Fractional functional differential equations with delay (FDDEs) have recently played a significant role in modeling of many real areas of sciences such as physics, engineering, biology, medicine, and economics. FDDEs often cannot be solved analytically so the approximate and numerical methods should be adapted to solve these types of equations. In this paper we consider a new method of backward differentiation formula- (BDF-) type for solving FDDEs. This approach is based on the interval approximation of the true solution using the Clenshaw and Curtis formula that is based on the truncated shifted Chebyshev polynomials. It is shown that the new approach can be reformulated in an equivalent way as a Runge-Kutta method and the Butcher tableau of this method is given. Estimation of local and global truncating errors is deduced and this leads to the proof of the convergence for the proposed method. Illustrative examples of FDDEs are included to demonstrate the validity and applicability of the proposed approach.

Abstract:

Based on the concept in Part 1, Theory and General Case, algorithms to determine the constrained R-T characteristic curve are established for convex constrained machining economics problems. The first algorithm is for posynomial problems with the linear-logarithmic tool life equation. The R-T curve may be determined by applying the simplex method to the log-dual problems. Sensitivity analysis of the optimal simplex tableau enables obtaining the loci of optima easily. The second algorithm is for the quadratic posylognomial problems with quadratic-logarithmic tool life equation using the property of primal-dual feasibility. End milling examples constructed in Part 1 illustrate the algorithm comparing to the exhaustive method.

Abstract:

The specification of communication behavior is fundamental in developing interoperable transactions. In particular, the temporal ordering of messages exchanged between different communicating agents must be declaratively specified and verified in order to guarantee consistency of data in the various component systems. This paper shows that by expressing communication constraints in propositional temporal logic, the tableau method can be applied to construct a dependency graph. If the specification is correct, this method guarantees that all possible execution paths satisfying the specification will be generated. The declarative specification and verification of communication constraints in interoperable transactions is demonstrated using the classic business trip. It is argued that the specification formalism provides an improvement over the Flexible Transaction Model.

Abstract:

Abstract In the paper we propose a new approach to formalization of cognitive logics. By cognitive logics we understand supraclassical, but non-trivial consequence operations, defined in a propositional language. We extend some paradigm of tableau methods, in which classical consequence Cn is defined, to stronger logics - monotonic, as well as non-monotonic ones - by specific use of non-classical tableau rules. So far, in that context tableaus have been treated as a way of formalizing other approaches to supraclassical logics, but we use them autonomically to generate various consequence operations. It requires a description of the hierarchy of non-classical tableau rules that result in different supraclassical consequence operations, so we give it.

Abstract:

Visuals – images – are a globally understandable exchange and copyable transmission of information. “O God, I could be bounded in a nutshell and count myself a king of infinite space,” Hamlet noticed. We also use our Coronavirus home office for experimental journeys in the Renaissance and Baroque periods. As in the 15th / 16th / 17th Century, worlds far away from us were discovered, and we embark on digital adventures that are temporary, simultaneous, synchronous, asynchronous, independent of location. We decided to work with digital photography as a visual method for mainly two reasons. First, taking photos can be done relatively easy during a shut down in the home office. We can train creativity and visual perception without being in a university's studio. Second, photographs can be analyzed and compared with paintings and therefore criticized by their motifs, aesthetic representation, and within their time frame. Our visual souvenirs are photographs and videos in the mirror of illusion, immersion, and imagination

Abstract:

Bibliometric analysis of publicity data on the handling of Covid-19 in Indonesia was carried out using Tableau and Vosviewer software. The research was conducted by using the literature search method using Google Scholar. The search was carried out from March 2020 to September 2020 using the keywords Covid-19 and Indonesia. The search results are then grouped based on author name, title and publication source. The results of grouping publications for Covid-19 handlers using Microsof Exel are grouped based on handling criteria. For publication sources analyzed using Software Tableau. Meanwhile, writer collaboration and keyword mapping were analyzed using the VosViewer software. The results of the analysis based on the criteria for handling Covid-19 show that most publications are in the form of treatment / prevention then followed by the impact / effect. Collaboration analysis using VosViewer software shows that Ian Huang is the most collaborative writer with 20 publications, followed by Raymond Pranata with 15 publications. The most publications on handling Covid-19 were published in Medica Hospitalia with 29 articles, followed by SALAM: Syar'i Social and Cultural Journal with 18 articles. Mapping results using VosViewer show that the handling of Covid-19 is divided into 4 clusters. Based on the visualization map, it is known that the most widely carried out research publications on Covid-19 are prevention / control in the context of accelerating the handling of the Covid pandemic, then followed by government policies in dealing with Covid-19 and economic policies during the Covid-19 pandemic.
