Abstract:

The appropriate timing of flowering is crucial for the reproductive success of plants. Hence, intricate genetic networks integrate various environmental and endogenous cues such as temperature or hormonal statues. These signals integrate into a network of floral pathway integrator genes. At a quantitative level, it is currently unclear how the impact of genetic variation in signaling pathways on flowering time is mediated by floral pathway integrator genes. Here, using datasets available from literature, we connect Arabidopsis thaliana flowering time in genetic backgrounds varying in upstream signalling components with the expression levels of floral pathway integrator genes in these genetic backgrounds. Our modelling results indicate that flowering time depends in a quite linear way on expression levels of floral pathway integrator genes. This gradual, proportional response of flowering time to upstream changes enables a gradual adaptation to changing environmental factors such as temperature and light.

Abstract:

Resumo Inspiradas por um projeto de modelagem matemática e pelas discussões teóricas que subsidiam os conceitos de pensamento numérico, pensamento geométrico e pensamento algébrico, nosso objetivo, neste artigo, é propor e caracterizar uma primeira versão de um constructo teórico denominado pensamento integral . O projeto de modelagem foi realizado por estudantes do 6º ano do Ensino Fundamental e um de seus propósitos era calcular a área superficial da lama que cobriu uma região do município de Brumadinho, em Minas Gerais, Brasil, após o rompimento da barragem de rejeitos de minério de ferro. Trata-se, portanto, de um ensaio empírico-teórico, por fundamentar-se em uma prática escolar de modelagem na educação matemática colocada em diálogo com referenciais teóricos. Mobilizamos problematizações sobre o ensino de integral, em especial a ideia de aproximação, e conceitos próprios da educação matemática na Educação Básica para, a partir da experiência no projeto de modelagem, descrever o conhecimento envolvido no cálculo de áreas de regiões com quaisquer formatos e que pode ser desenvolvido por estudantes do Ensino Fundamental.

Abstract:

The paper deals with the modelling of globalization and integration processes which fundamentally influence enterprise functioning, subject and business forms in both the internal and external trade. Final output is the result of internationally coordinated production in many sectors. The impact of this process is that costs of inputs are minimized and intermediate products are made in different countries. As capital becomes more mobile and technology facilitates international communication, national borders become more permeable to economic activity. Economic reality that is the aim of this modelling is changing and due to this it is necessary to adjust modelling techniques analysed in this paper.

Abstract:

Context. The modelling of stationary galactic stellar populations can be performed using distribution functions. Aims. This paper aims to write explicit integrals of motion and distribution functions. Methods. We propose an analytic formulation of the integrals of motion with an explicit dependence on potential. This formulation applies to potentials with rotational symmetry or triaxial symmetry. It is exact for Stäckel potentials and approximate for other potentials. Results. Modelling a stationary stellar population using these integrals of motion allows the force field to be found with satisfactory accuracy. On the other hand, the mass density distribution that generates the force field and the gravitational potential is recovered with less accuracy due to lower precision in modelling box-type orbits.

Abstract:

Il nefrologo, che si confronta con tutti i problemi inerenti all'insufficienza renale, è anche da sempre principale gestore della terapia emodialitica. Per tale motivo tocca al nefrologo, in prima istanza, occuparsi dell'accesso vascolare disponendone l'allestimento, la sorveglianza e la manutenzione a garanzia della possibilità di effettuare il trattamento sostitutivo. Rispetto a quanto avviene in altri paesi, in Italia l'attività dell'accesso non è ad oggi standardizzata né strutturata; ciascun centro dialisi si organizza in funzione delle capacità dei nefrologi ivi operanti e delle collaborazioni di altri specialisti presenti nell'ospedale, spesso senza un percorso strutturato e con modalità di intervento per lo più fondate sulla disponibilità personale e sul volontarismo. Partendo dalla storia dell'accesso vascolare in Italia, abbiamo individuato tre tipologie organizzative che correlano, da un lato, con il contesto storico in cui sono sorte e, dall'altro, con il progresso, in termini di dispositivi medici e competenze specialistiche, che ha via via modificato i comportamenti. Il modello organizzativo “primordiale” vede il nefrologo confezionare e correggere personalmente gli accessi disponibili in quell'epoca. Nel modello polispecialistico, che nasce successivamente, il nefrologo inizia a delegare ad alti specialisti, più competenti sul versante tecnico, singole fasi del lavoro; resta colui che inizia il percorso e detta i tempi ma perde, talora, il controllo della gestione complessiva. Nel modello strutturale integrato, ideale ma non ancora integralmente realizzabile, il chirurgo dedicato all'accesso dialitico ed il radiologo interventista interagiscono da vicino con il nefrologo, che funge da regista, coordinatore e amministratore di tutto il processo di gestione dell'accesso vascolare. La formazione culturale specifica e necessaria e la conoscenza del programma terapeutico complessivo sono condivise dal team dell'accesso. In tale modello integrato dovrebbero essere trovate soluzioni perché anche la responsabilità professionale ed il rimborso amministrativo risultino bene “integrate” tra i vari specialisti ed operatori sanitari che partecipano all'attività. Il rimborso a D.R.G. com'è attualmente regolato presenta incongruenze e può produrre effetti contrari alla migliore cura del paziente. Le Aziende ospedaliere attualmente non riservano all'accesso vascolare, parte irrinunciabile della terapia dialitica, l'attenzione necessaria e non comprendono come una corretta gestione del problema, fondata su percorsi organizzati, migliori la qualità di vita del paziente e contenga il costo assistenziale della dialisi. La gestione complessiva dell'accesso vascolare dialitico non può più fondarsi, attualmente, solo sulla “buona volontà” del nefrologo dializzatore, ma richiede regole strutturali. Pertanto andrebbero definite le motivazioni professionali mediante l'attribuzione di precisi compiti, con lo scopo di meglio identificare e minimizzare il “rischio organizzativo”. L'individuazione di meccanismi economico-organizzativi-normativi che privilegino anzitutto l'ottenimento del risultato e, a seguire, che premino il lavoro di tutta la squadra che l'ha generato è la condizione prima per creare il modello integrato. è più che mai tempo che l'accesso vascolare entri a pieno titolo nel sistema qualità della dialisi e per farlo, a nostro avviso, il modello organizzativo integrato è l'unica soluzione possibile.

Abstract:

The geometric heights obtained from GNSS observations cannot be used for engineering works as they are not reduced to the geoid. This study presents practical local geoid modelling from gravimetric observations using the modified Stokes integral for engineering applications in Benin City. A total of 52 points were observed with GNSS receivers and a gravimeter to respectively obtain their positions and absolute gravity values. The theoretical gravity values of the points were computed on the Clarke 1880 ellipsoid to obtain their local gravity anomalies. The modified Stokes integral was applied to compute the geoid heights of the points. The combined topographic effect was applied to the computed geoid heights of the points to obtain their precise geoid heights. The mean of the precise geoid heights of the points was computed to obtain the local gravimetric geoid model of the study area. The determined geoid model was validated for its reliability as well as the accuracy using the RMSE index. It is recommended that the use of assumed, as well as handheld GPS receiver heights for engineering works should be totally abolished as this study has established the local geoid model of Benin City.

Abstract:

In this letter we show how to use a new form of integration, called dynamical integration, that utilizes the dynamics of a system defined by an ODE to construct a map that is in effect a one-step integrator. This method contrasts sharply with classical numerical methods that utilize polynomial or rational function approximations to construct integrators. The advantages of this integrator is that it uses only one step while preserving important dynamical properties of the solution of the ODE: First, if the ODE is conservative, then the one-step integrator is measure preserving. This is significant for a system having a highly nonlinear component. Second, the one-step integrator is actually a one-parameter family of one-step maps and is derived from a continuous transformation group as is the set of solutions of the ODE. If each element of the continuous transformation group of the ODE is topologically conjugate to its inverse, then so is each member of the one-parameter family of one-step integrators. If the solutions of the ODE are elliptic, then for sufficiently small values of the parameter, the one-step integrator is also elliptic. In the limit as the parameter of the one-step family of maps goes to zero, the one-step integrator satisfies the ODE exactly. Further, it can be experimentally verified that if the ODE is chaotic, then so is the one-step integrator. In effect, the one-step integrator retains the dynamical characteristics of the solutions of the ODE, even with relatively large step sizes, while in the limit as the parameter goes to zero, it solves the ODE exactly. We illustrate the dynamical, in contrast to numerical, accuracy of this integrator with two distinctly different examples: First we use it to integrate the unforced Van der Pol equation for large ∊, ∊≥10 which corresponds to an almost continuous square-wave solution. Second, we use it to obtain the Poincaré map for two different versions of the periodically forced Duffing equation for parameter values where the solutions are chaotic. The dynamical accuracy of the integrator is illustrated by the reproduction of well-known strange attractors. The production of these attractors is eleven times longer when using a conventional fourth-order predictor-corrector method. The theory presented here extends to higher dimensions and will be discussed in detail in a forthcoming paper. However, we caution that the theory we present here is not intended as a line of research in numerical methods for ODEs.

Abstract:

The modelling of OXPHOS (oxidative phosphorylation) in order to integrate all kinetic and thermodynamic aspects of chemiosmotic theory has a long history. We briefly review this history and show how new ways of modelling are required to integrate a local model of the individual respiratory complexes into a global model of OXPHOS and, beyond that, into a reliable overall model of central metabolism.

Abstract:

In this paper we propose STEAM practices that would foster mathematics learning through modelling architecture while connecting to culture and history. The architectural modelling process is applied by the teachers as participants of these practices from different countries allowing a broad cultural and historical connection to mathematics education. The modelling is implemented in GeoGebra platform as it is an open-source platform to allow teachers to model on a mathematics basis. The architectural modelling process does not provide participants with steps to follow but rather allows them to explore the architectural models’ components and construct them with various approaches which may foster problem solving techniques. We aim to investigate how different phases of this approach (such as motivation, modeling, and printing process) reflect on opportunities of learning in STEAM education, with a particular lens in mathematical development from open tasks. This paper will show two use cases that took place in Upper Austria and the MENA region.

Abstract:

This article has two goals. Firstly, it shows how a relatively novel technique (Agent Based Modelling, hereafter ABM) can integrate different data types that are often used only in separate strands of research (interviews, experiments and surveys). It does this by comparing a well-known ABM of attitude dynamics with an alternative model using data from surveys and experiments. Secondly, the article explains ABM methodology and why it is important to the distinctiveness of ABM as a research method. In particular, the ramifications of differing approaches to ABM calibration and validation are discussed using the two different ABM as examples. The article concludes by showing how ABM might provide a progressive research strategy for integrating different data types and thus different disciplines in attitude research.

Abstract:

Within the framework of the research and innovation strategy RIS3 “Sustainable Living” (POR-FSE, funded by the Veneto Region), for the improvement of the resilience and adaptation capacity of the Veneto territory to environmental crises and emergencies, the subject of the contribution returns the results of the participatory experimentation of the project H.E.L.P. Veneto ‘ High-efficiency Emergency Living Prototypes Veneto - Sustainable adaptive residences for temporary stay in environmental emergencies. The research concerns the design of a minimum flexible emergency living module, replicable on a large scale, multifunctional, sustainable, powered by off-grid systems and integrated into the built environment. The housing unit uses timber, a material linked to the local building tradition, whose prefabricated modular reversibility follows principles of circular reuse. Moreover, the constructive adaptability of the interior spaces is reflected in a “liquid space” capable of transforming itself according to the needs of the occupants. The paper introduces a form of participatory design of the emergency housing module, based on the engagement of small and large companies, related to different segments of the construction market, a leading sector in the economy of Veneto. The participatory approach borrows from Architectural Technology the tools needed to understand the characteristics of the settlement system, the potential of the project and the value of scientific stakeholder engagement in the process. Using the Soft System Methodology, direct investigation protocols have been constructed relating to the performance of the living unit. Using Strategic Options Development and Analysis (SODA), the results of the experimented survey (large-scale questionnaires) were decoded, interpreted and systematised. The processing of the answers allowed the stakeholders to validate the potential of the proposed module and, at the same time, to be informed about its characteristics. The innovation of the method lies precisely in the modelling phase, which makes it possible to integrate the results of the hard and soft data analyses and to make it clear how participation plays an essential role in the process of designing and validating the proposed module. Nell’ambito della strategia di ricerca e innovazione RIS3 “Sustainable Living” (POR-FSE, finanziato dalla regione Veneto), per il miglioramento della capacità di resistenza e di adattamento del territorio veneto a crisi ed emergenze ambientali, l’oggetto del contributo restituisce gli esiti della sperimentazione partecipata del progetto H.E.L.P. Veneto High efficiency Emergency Living Proto- types Veneto – Residenze adattive sostenibili per la permanenza temporanea in regime di emergenza ambientale. La sperimentazione riguarda la progettazione di un modulo minimo abitativo di emergenza flessibile, repli- cabile a larga scala, polifunzionale, sostenibile con impianti a funzionamento off-grid e integrato nell’ambiente costruito. L’unità abitativa utilizza il legno, materiale legato alla tradizione costruttiva locale, la cui reversibilità modulare prefabbricata segue principi di riuso circolare. Inoltre, l’adattabilità costruttiva degli ambienti interni si riflette in uno “spazio liquido” capace di trasformarsi in base alle esigenze dell’abitare. Il contributo propone una forma di progettazione partecipata del modulo abitativo emergenziale, basata sull’engagement delle realtà aziendali di piccole e grandi dimensioni, relative ai diversi segmenti di mercato dell’edilizia, settore trainante della regione Veneto. L’approccio partecipativo mutua dalla Tecnologia dell’Architettura gli strumenti di conoscenza atti alla comprensione delle caratteristiche del sistema insediativo, delle potenzialità del progetto e del valore dell’engagement scientifico degli stakeholder nel processo. Utilizzando la Soft System Methodology sono stati costruiti dei protocolli di indagine diretta che combinano la conoscenza prestazionale dei processi insediativi nell’unità ambientale. Mediante la Strategic Options Development and Analysis (SODA) sono stati decodificati, interpretati e sistematizzati i risultati della survey sperimentata (questionari ad ampia scala). L’elaborazione delle risposte ha fatto sì che il sapere esperto degli stakeholder validasse le potenzialità del modulo proposto informandosi, al contempo, sulle caratteristiche dello stesso. L’innovazione del metodo risiede proprio nella fase di modellazione, la quale permette di integrare i risultati delle analisi dei dati hard e quelle dei dati soft, e di rendere chiaro come la partecipazione svolga un ruolo essenziale nel processo di animazione e validazione del modulo proposto.

Abstract:

The work is devoted to the development and modelling of the system of pulse current measurement during high-voltage tests and experiments. The proposed measurement system is based on the application of Rogowski coil with non-inverting integrator. The results of numerical modelling of the developed current measurement system are compared with the results of application of a low-inductance shunt resistor, Rogowski coil with passive RC-integrator and Rogowski coil with inverting active integrator in similar measurement systems. Various standard pulse currents including steep edge pulse (1/20 µs), large amplitude current pulse (4/10 µs), lightning pulse current (8/20 µs), switching pulse current (30/80 µs), and 1-3 ms pulse currents are modelled for the comparative test. From the simulation results, it follows that the developed Rogowski coil with the proposed non-inverting integrator has sufficiently high accuracy in a wide frequency band overlapping the frequency band of standard pulse currents in high-voltage tests.

Abstract:

Ontology engineering, along with semantic Web technologies, allow the semantic development and modeling of the operational flow required for blockchain design. The semantic Web, in accordance with W3C, provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries, and can be seen as an integrator for various content, applications and information systems. The most widely used blockchain modelling system, by abstract representation, description and definition of structure, processes, information and resources, is the enterprises modelling. Enterprise modelling uses domain ontologies by model representation languages.

Abstract:

Abstract Modelling the cosmic large-scale structure can be done through numerical N-body simulations or by using perturbation theory. Here, we present an N-body approach that effectively implements a multi-step forward model based on Lagrangian Perturbation Theory (LPT) in a ΛCDM Universe. This is achieved by introducing the second-order accurate BullFrog integrator, which automatically performs 2LPT time steps to second order without requiring the explicit computation of 2LPT displacements. Importantly, we show that BullFrog trajectories rapidly converge to the exact solution as the number of time steps increases, at any moment in time, even though 2LPT becomes invalid after shell-crossing. As a validation test, we compare BullFrog against other N-body integrators and high-order LPT, both for a realistic ΛCDM cosmology and for simulations with a sharp UV cutoff in the initial conditions. The latter scenario enables controlled experiments against LPT and, in practice, is particularly relevant for modelling coarse-grained fluids arising in the context of effective field theory. We demonstrate that BullFrog significantly improves upon other LPT-inspired integrators, such as FastPM and COLA, without incurring any computational overhead compared to standard N-body integrators. Implementing BullFrog in any existing N-body code is straightforward, particularly if FastPM is already integrated.

Abstract:

The fact that traditional price/cost models are unrelated to the construction process renders them largely unsuited to the provision of meaningful price/cost advice. The nature and lengthiness of the construction planning process has precluded its incorporation into price/cost modelling during the pre-tender phase of the traditional building procurement process. The nub of the modelling problem has been how to integrate the complex process of construction planning into the pre-tender price/cost modelling process. In this paper the authors propose the synthesis of artificial intelligence techniques and construction planning techniques, resulting in a conceptual framework for a network-based cost modelling system for use by quantity surveyors in the cost modelling of buildings.

Abstract:

While security assessments of information systems are being increasingly performed with support of security modelling, safety assessments are still undertaken with traditional techniques such as Failure Mode and Effect Analysis (FMEA). As system modelling is becoming an increasingly important part of developing more safety critical systems, the safety field can benefit from security techniques that integrate system modelling and security aspects. This paper adapts an existing security modelling technique, Misuse Sequence Diagrams, to support failure analysis. The resulting technique, called Failure Sequence Diagrams, is used to support Failure Mode and Effect Analysis in an industrial setting. Based on the experiences, the authors suggest improvements both to traditional safety techniques and to security and safety modelling.

Abstract:

Building information modelling (BIM) is increasingly appropriate for infrastructure projects, and in particular for transport infrastructure. It is a digital solution that integrates the practices of the construction industry in facility management during the whole life cycle. This integration is possible through a single tool, which is the 3D digital model. Nevertheless, BIM standards, such as industry foundation classes, are still in the pipeline for infrastructure management. These standards do not fully meet the requirements of operation and maintenance of transport infrastructure. This paper shows how BIM could be implemented to address issues related to the operation and maintenance phase for transport infrastructure management. For this purpose, a new ontological approach, called Industry Foundation Classes for Operation and Maintenance of Infrastructures (IFCInfra4OM), is detailed. This ontology aims to standardise the use of building information modelling for operation and maintenance in road infrastructures. To highlight the interest of the proposed ontological approach, a building information model of a section on the A7 Agadir–Marrakech Highway in Morocco is produced according to IFCInfra4OM. The methodology is presented. The results obtained, including the IFCInfra4OM data model, are submitted. In the last section, an overview of the IFC extension approach is submitted.

Abstract:

SummaryApproaches using breeding, physiology and modelling for evaluating adaptation of plant genotypes to target environments are discussed and methods of characterizing the target environments outlined. Traditional approaches, and their limitations, to evaluation of genotypic adaptation using statistical and classificatory techniques with a phenotypic model are discussed. It is suggested that a simple biological model is the most appropriate framework in which to integrate physiology and modelling with plant breeding. Methods by which physiology and modelling may contribute to assessment of adaptive traits and to selection for adaptation in a breeding programme are considered.

Abstract:

The investigation (i.e. modelling, simulation, understanding and control) of complex adaptive systems is a problematic issue mainly due to the immaturity of systems scientific modelling paradigms. The apparent analogies between complex adaptive systems and production networks provide the opportunity to formulate the latter one in terms of the first, and to integrate the knowledge and the way of thinking of both fields. Through the application of the method of analogy and agent-based modelling and the development of a methodology a disciplined way of thinking is presented that involves the formulation of natural scientific concepts in terms of simulation models.

Abstract:

This paper presents a comprehensive study of triple integrals, extending the conventional understanding of volumetric integration to encompass a broader class of functions and domains. We introduce a novel framework for defining and evaluating these integrals, particularly focusing on cases where the integrand or the region of integration exhibits discontinuities, singularities. Utilizing concepts from measure theory and functional analysis, we develop techniques for establishing the existence and uniqueness of total triple integrals under relaxed regularity conditions. A significant contribution is the establishment of a generalized total triple integrals. We further explore applications of these integrals in physics, specifically in modelling heterogeneous materials and non-equilibrium systems, where conventional integration methods prove inadequate. Triple integrals play a crucial role in various digital applications, particularly in fields like computer graphics, image processing, machine learning, and signal processing. These integrals enable the computation of volumetric properties, aiding in tasks such as 3D rendering, object recognition, and spatial data analysis. In computer graphics, triple integrals help simulate realistic lighting, shading, and textures. In image processing, they assist in reconstructing 3D models from medical scans and volumetric data. Machine learning utilizes triple integrals in probability density estimation and feature extraction from multidimensional datasets. Other applications include 3D scanning, AR/VR development, and robotics, where they contribute to path planning and spatial mapping. Overall, triple integrals are indispensable in advancing digital technologies that rely on 3D data representation and analysis.

Abstract:

In this paper, adaptive compensation with a robust integral of the sign of the extended error (RISEE) feedback is developed for high precise tracking control of systems in the presence of simultaneous structured and unstructured uncertainties. To handle various uncertainties existing in the system in one controller, we propose an adaptive RISEE controller (ARISEE), in which an adaptive law based on the improved discontinuous projection method is synthesized to handle parametric uncertainties and the RISEE robust term to attenuate unmodelled disturbances. Moreover, the present controller does not need a priori knowledge on the bounds of the lumped disturbances and the gain of the designed robust control law can itself be tuned. The major feature of the proposed controller is that it can theoretically guarantee global asymptotic tracking performance with a continuous control input, in the presence of parametric uncertainties and unmodelled disturbances via Lyapunov analysis. Comparative numerical results verify the effectiveness of the proposed non-linear controller.

Abstract:

Abstract. Nowadays, the extensive use of Monte Carlo methods in various fields has promoted the scientific decision-making, improved the efficiency of social operation, and enabled better management of many uncertain factors in daily life. However, in some cases, traditional Monte Carlo methods doesn't work so well because of the excessive variance. This paper aims to explore a new numerical integration method called splitting method to minimize intrinsic variance in Monte Carlo simulations. Through this innovative method, we found that the variance was reduced significantly. Despite some oscillating functions which are still difficult to estimate because they have too many turning points, this study provides new insights into variance reduction in Monte Carlo for integrals to optimize calculations in various fields when the modelling functions are not monotonic.
