Subjects: subject: Reihenfolgeproblem

description: In ersten Teil des Vortrages wird eine Heuristik zur Approximation der Pareto Menge multikriterielle verallgemeinerter Job-Shop Scheduling-Probleme vorgestellt. Der Algorithmus basiert auf einer genetischen lokale Suche Heuristik. Die Mittelwertbildung der Startzeiten der Vorgänge wurde hierbei als Rekombinationsoperator verwendet. Als lokale Suche wurde ein Threshold Accepting Algorithmus implementiert. Der Algorithmus wurde auf einer großen Menge von Benchmark-Instanzen und den Zielfunktionen Makespan, Tardiness, Lateness und Summe der Fertigstellungszeiten getestet. Die Ergebnisse zu den verschiedenen Zielfunktionen werden vorgestellt. Die vom Algorithmus erzeugte Approximation der Pareto Menge kann eine große Anzahl von Lösungen enthalten. Aus dieser Menge muss der Entscheidungsträger eine Lösung auswählen. Da die Datenmenge schon bei moderaten Problemdimensionen sehr umfangreich wird, stellt dies ein Problem für den Entscheider dar. Deshalb muss die große Menge der Lösungen auf eine überschaubare Anzahl reduziert werden. Bei dieser Reduktion der Lösungen muss die Diversität der verbleibenden Lösungen beachtet werden. Diese Reduzierung wird als Short Listing bezeichnet und im zweiten Teil des Vortrages vorgestellt. Im ersten Schritt des Short Listings werden die Lösungen mittels Abstandsmaßen im Lösungsraum geclustert. Die dazu verwendeten Abstandsmaße werden auf den Permutationen der Vorgänge auf den Ressourcen definiert. Es wurden fünf Abstandsmaße und zwei Clusterverfahren, ein hierarchisches und ein nicht-hierarchisches, untersucht. Im zweiten Schritt wird aus jedem Cluster jeweils eine Lösung ausgewählt und dem Entscheidungsträger vorgelegt. Dabei wurden zwei Methoden untersucht. Im ersten Fall wurde die bezüglich einer Ranking-Funktion beste Lösung und im zweiten Fall die Medianlösung bezüglich des Abstandsmaßes ausgewählt. Die Abstandsmaße, Clusteralgorithmen und Auswahlmethoden wurden auf einer großen Menge von Benchmark-Instanzen verglichen. Die Ergebnisse werden im Vortrag vorgestellt.

description: An approximate analytical technique for assessing the reliability of a softening Duffing oscillator subject to evolutionary stochastic excitation is developed. Specifically, relying on a stochastic averaging treatment of the problem the oscillator time-varying survival probability is determined in a computationally efficient manner. In comparison with previous techniques that neglect the potential unbounded response behavior of the oscillator when the restoring force acquires negative values, the herein developed technique readily takes this aspect into account by introducing a special form for the oscillator non-stationary response amplitude probability density function (PDF). A significant advantage of the technique relates to the fact that it can readily handle cases of stochastic excitations that exhibit strong variability in both the intensity and the frequency content. An illustrative numerical example of a softening Duffing oscillator subject to earthquake excitation is included. Comparisons with pertinent Monte Carlo simulation data demonstrate the efficiency of the technique.

description: In recent years, the emergence and development of third-party platforms have greatly facilitated the growth of the Online to Offline (O2O) business. However, the large amount of transaction data raises new challenges for retailers, especially anomaly detection in operating conditions. Thus, platforms begin to develop intelligent business assistants with embedded anomaly detection methods to reduce the management burden on retailers. Traditional time-series anomaly detection methods capture underlying patterns from the perspectives of time and attributes, ignoring the difference between retailers in this scenario. Besides, similar transaction patterns extracted by the platforms can also provide guidance to individual retailers and enrich their available information without privacy issues. In this paper, we pose an entity-wise multivariate time-series anomaly detection problem that considers the time-series of each unique entity. To address this challenge, we propose GraphAD, a novel multivariate time-series anomaly detection model based on the graph neural network. GraphAD decomposes the Key Performance Indicator (KPI) into stable and volatility components and extracts their patterns in terms of attributes, entities and temporal perspectives via graph neural networks. We also construct a real-world entity-wise multivariate time-series dataset from the business data of Ele.me. The experimental results on this dataset show that GraphAD significantly outperforms existing anomaly detection methods.

description: Many scientific workflow scheduling algorithms need to be informed about task runtimes a-priori to conduct efficient scheduling. In heterogeneous cluster infrastructures, this problem becomes aggravated because these runtimes are required for each task-node pair. Using historical data is often not feasible as logs are typically not retained indefinitely and workloads as well as infrastructure changes. In contrast, online methods, which predict task runtimes on specific nodes while the workflow is running, have to cope with the lack of example runs, especially during the start-up. In this paper, we present Lotaru, a novel online method for locally estimating task runtimes in scientific workflows on heterogeneous clusters. Lotaru first profiles all nodes of a cluster with a set of short-running and uniform microbenchmarks. Next, it runs the workflow to be scheduled on the user's local machine with drastically reduced data to determine important task characteristics. Based on these measurements, Lotaru learns a Bayesian linear regression model to predict a task's runtime given the input size and finally adjusts the predicted runtime specifically for each task-node pair in the cluster based on the micro-benchmark results. Due to its Bayesian approach, Lotaru can also compute robust uncertainty estimates and provides them as an input for advanced scheduling methods. Our evaluation with five real-world scientific workflows and different datasets shows that Lotaru significantly outperforms the baselines in terms of prediction errors for homogeneous and heterogeneous clusters.

description: We consider an industrial application consisting of the mass minimization of a frame in an injection moulding machine. This frame has to compensate the forces acting on the mould inside the machine and has to fulfill certain critical constraints. The deformation of that frame with constant thickness is described by the plain stress state equations for linear elasticity. If the thickness varies then we use a generalized plain stress state with constant thickness in the coarse grid elements. These direct problems are solved by an adaptive multigrid solver. The mass minimization problem leads to a constrained minimization problem for a non-linear functional which will be solved by some standard optimization algorithm which requires the gradients with respect to design parameters. For the shape optimization problem, we assume that the machine components consist of simple geometrical primitives determined by a few design parameters. Therefore, we calculate the gradient in the shape optimization by means of numerical differentiation which requires the solution of approximately 4 direct problems per design parameter. The adaptive solver guarantees the detection of critical regions automatically, and ensures a good approximation to the exact solution of the direct problem. This rather slow approach can be significantly accelerated by using the adjoint method to express the gradient. It will be combined with a direct implementation of several terms that appear after applying the chain rule to the gradient.

description: Digital images are commonly represented as regular 2D arrays, so pixels are organized in form of a matrix addressed by integers. However, there are many image processing operations, such as rotation or motion compensation, that produce pixels at non-integer positions. Typically, image reconstruction techniques cannot handle samples at non-integer positions. In this paper, we propose to use triangulation-based reconstruction as initial estimate that is later refined by a novel adaptive denoising framework. Simulations reveal that improvements of up to more than 1.8 dB (in terms of PSNR) are achieved with respect to the initial estimate.

Simulation of strongly non-Gaussian non-stationary stochastic processes utilizing Karhunen-Loeve expansion
Creators: name: Kim, Hwanpyo
name: Shields, Michael D.
Publisher: name: The University of British Columbia
Year: 2015

description: The simulation of non-stationary and non-Gaussian stochastic processes is a challenging problem of considerable practical interest. Recently, Shields et al. have developed a class of conceptually simple and efficient methods for simulation of non-Gaussian processes using translation process theory (collectively referred to as the Iterative Translation Approximation Method - ITAM) that iteratively upgrades the underlying Gaussian power spectral density function for simulation using the spectral representation method. However, the currently existing ITAM method for generation of non-stationary and non-Gaussian processes requires additional approximations in the estimation of the evolutionary spectrum. An extension of the ITAM is proposed that utilizes the K-L expansion. The developed method iteratively upgrades the covariance function directly and, in so doing, avoids the complex and non-unique inverse problem of estimating the evolutionary spectrum from the non-stationary autocorrelation. The application of the method for a strongly non-Gaussian and non-stationary process with a prescribed target non-Gaussian correlation function is demonstrated.

description: This paper introduces a method to generate adequate inclusion-matrix geometries of concrete in two and three dimensions, which are independent of any specific numerical discretization. The article starts with an analysis on shapes of natural aggregates and discusses corresponding mathematical realizations. As a first prototype a two-dimensional generation of a mesoscale model is introduced. Particle size distribution functions are analysed and prepared for simulating an adequate three-dimensional representation of the aggregates within a concrete structure. A sample geometry of a three-dimensional test cube is generated and the finite element analysis of its heterogeneous geometry by a uniform mesh is presented. Concluding, aspects of a multiscale analysis are discussed and possible enhancements are proposed.

description: Accurately representing the complexity of hydrologic processes remains a central challenge in water resources modeling, particularly due to limitations in traditional evaluation methods that rely heavily on streamflow alone. This dissertation addresses this gap by exploring the integration of Earth Observations (EO)—specifically evapotranspiration (ET), soil moisture (SM), and leaf area index (LAI)—into hydrologic modeling to enhance model reliability and internal process consistency. First, a novel tool, HydroMET-EO, was developed as the first desktop-based, semi-automatic software designed to bridge interoperability barriers between EO datasets and hydrologic model outputs. Demonstrated through case studies, HydroMET-EO enabled detailed sub-watershed model evaluations, revealing discrepancies not captured by streamflow-only assessment. Second, multi-variable model evaluation using EO-based ET and SM across 15 basins confirmed that strong streamflow performance does not necessarily equate to accurate representation of hydrologic processes. The results highlighted that EO integration improves diagnostic insight, particularly in ungauged areas. Third, the effectiveness of EO data assimilation was examined across three diverse basins using PET and LAI, revealing that spatial and temporal scales of assimilation must be tailored to watershed characteristics for optimal results. Improvements in streamflow, AET, and SM were most pronounced at yearly temporal scales and finer spatial resolutions in ecohydrologically sensitive basins. Collectively, the research contributes a practical evaluation tool, empirical evidence supporting EO-informed validation, and strategic guidance on data assimilation, advancing the field toward more transparent, robust, and process-consistent hydrologic modeling. These findings promote the integration of EO into mainstream modeling workflows, supporting both scientific progress and water resource decision-making.

description: Error concealment is of great importance for block-based video systems, such as DVB or video streaming services. In this paper, we propose a novel scalable spatial error concealment algorithm that aims at obtaining high quality reconstructions with reduced computational burden. The proposed technique exploits the excellent reconstructing abilities of the kernel-based minimum mean square error K-MMSE estimator. We propose to decompose this approach into a set of hierarchically stacked layers. The first layer performs the basic reconstruction that the subsequent layers can eventually refine. In addition, we design a layer management mechanism, based on profiles, that dynamically adapts the use of higher layers to the visual complexity of the area being reconstructed. The proposed technique outperforms other state-of-the-art algorithms and produces high quality reconstructions, equivalent to K-MMSE, while requiring around one tenth of its computational time.

Durch selektive Kopplung von Tragwerks- und Querschnittsmodellen in ausgewählten Bereichen der Konstruktion kann z.B. eine Verbesserung der Abbildungsgenauigkeit erzielt werden. Dadurch werden erweiterte Aussagen über das Querschnittstragverhalten in extrem beanspruchten Teilen des Tragwerks bei optionaler Skalierbarkeit des Modellumfangs möglich. Im Beitrag werden ausgewählte Varianten der Modellbildung gegenübergestellt und bewertet. Hierbei werden Aspekte der physikalischen Nichtlinearität von hybriden Konstruktionen insbesondere von Stahlbetonkonstruktionen berücksichtigt. Die Einbeziehung von Verfahren der mathematischen Optimierung in die Berechnungsstrategie ermöglicht die Lösung der zugrunde liegenden nichtlinearen Problemstellungen unter Vorgabe von Bemessungszielen und unter Beachtung von Grenzzustandsbedingungen.

description: Nowadays, 2D barcodes have been widely used for advertisement, mobile payment, and product authentication. However, in applications related to product authentication, an authentic 2D barcode can be illegally copied and attached to a counterfeited product in such a way to bypass the authentication scheme. In this paper, we employ a proprietary 2D barcode pattern and use multimedia forensics methods to analyse the scanning and printing artefacts resulting from the copy (rebroadcasting) attack. A diverse and complementary feature set is proposed to quantify the barcode texture distortions introduced during the illegal copying process. The proposed features are composed of global and local descriptors, which characterize the multi-scale texture appearance and the points of interest distribution, respectively. The proposed descriptors are compared against some existing texture descriptors and deep learning-based approaches under various scenarios, such as cross-datasets and cross-size. Experimental results highlight the practicality of the proposed method in real-world settings.
Determination of soil property characteristic values from standard penetration tests

Publisher: name: The University of British Columbia
Year: 2015

description: Characteristic values of soil property is a key element in geotechnical design guidelines, particularly for probability-based design codes, and it is usually defined as a pre-specified quantile, such as a lower 5% quantile in Eurocode 7, of the probability distribution of soil property. Such a probabilistic characterization requires a large number of data points from laboratory and/or in situ tests, which are usually not available for most geotechnical projects, especially for those with medium or small sizes. For most projects, only a limited number of standard penetration test (SPT) N values are generally available. It is therefore rather challenging to determine the probability distribution and characteristic values for geotechnical design. To address this challenge, this paper presents a Bayesian equivalent sample approach that determines the probability distribution and characteristic value of effective friction angle and Young’s modulus using only a limited number of SPT N values. Two case histories are used to illustrate the approach.

Pre-posterior optimization of sequence of measurement and intervention actions under structural reliability constraint

description: When, based on the available information, an existing structure has an estimated failure probability above the admissible level, the default solution often is to either strengthen or replace it. Even if this practice is safe, it may not be the most economical. In order to economically restore and improve our existing infrastructure, the engineering community needs to be able to assess the potential gains associated with reducing epistemic uncertainties using measurements, before opting for costly intervention actions, if they become necessary. This paper provides a pre-posterior analysis framework to (1) optimize sequences of actions minimizing the expected costs and satisfying reliability constraints, and (2) quantify the potential gain of making measurements in existing structures. Illustrative examples show that when the failure probability estimated based on the present state of knowledge does not satisfy an admissible threshold, strengthening or replacement interventions can be sub-optimal first actions. An example shows that significant savings can be achieved by reducing epistemic uncertainties.

We make use of the size-dependency based ansatz i.e., RS parameter, $γ$, is a functional of density, $ρ(\mathbf{r})$, of which not much is known. To be consistent with this ansatz, a novel procedure is presented that relates the characteristic length of a given system (where $ρ(\mathbf{r})$ exponentially decays to zero) with $γ$ self-consistently via a simple mathematical constraint. In practice, $γ_{\mathrm{OT}}$ is obtained through an optimization of total energy as follows: $γ_{\mathrm{OT}} \equiv \underset{γ}{\mathrm{opt}} \ E_{\mathrm{tot},γ}$. It is found that the parameter $γ_{\mathrm{OT}}$, estimated as above can show better performance in predicting properties (especially from frontier orbital energies) than conventional respective RSH functionals, of a given system. We have examined the nature of highest fractionally occupied orbital from exact piece-wise linearity behavior, which reveals that this approach is sufficient to maintain this condition. A careful statistical analysis then illustrates the viability and suitability of the current approach. All the calculations are done in a Cartesian-grid based pseudopotential (G)KS-DFT framework.

description: Three-component alkene difunctionalization reactions constitute an ideal platform to rapidly build molecular complexity, enabling the simultaneous introduction of two distinct, orthogonal functional groups into the C═C bond in a single step. Herein, a photoredox catalyzed Ritter-type carboamidation of electronically diverse styrenes harnessing non-stabilized, nucleophilic primary radicals generated from readily-accessible carboxylic acid-derived redox active esters is reported. Furthermore, it is found that Heck-type products are chemoselectively obtained by simply switching aryl olefin acceptors with 1,1-diarylolefins. In the context of photocatalytic chemodivergent radical polar crossover, the synthesis of various trisubstituted alkenes was achieved, simultaneously revealing a divergence in the activation of redox-active esters toward reduction. In-depth mechanistic studies demonstrated both transformation pathways, while DFT calculations indicated the origin of product switchability. Both Ritter-type and Heck-type olefin carbofunctionalizations are scalable up to 4 mmol scale in batch and continuous flow, proving the synthetic utility of the methodology.

description: Objektorientierte Anwendungen aus dem Ingenieurwesen bestehen aus strukturierten Mengen, deren Elemente Objekte sind. Zwischen den Objekten bestehen vielfältige Abhängigkeiten. Die Beziehungen sind zur Zeit der Entwicklung einer Anwendung nur teilweise bekannt. Beziehungen zwischen Objekten müssen deshalb auch zur Laufzeit der Anwendung erzeugt und gelöscht werden können. Aufgrund des hohen Rechenaufwandes wird die Objektbasis einer Anwendung verzögert aktualisiert. Eine objektorientierte Anwendung wird auf Grundlage der Systemtheorie als System formal beschrieben. Als Elemente des Systems werden Attribute, Objekte und Objektmengen eingeführt. Die in den Methoden der Objekte implementierten Algorithmen bestimmen die Bindungsrelation des Systems. Auf Grundlage der Graphentheorie wird die Reihenfolge der Aktualisierung der Objektbasis berechnet. ...

description: Der lebensdauerorientierte Entwurf von Stabbogenbrücken, mit Zuschnitt auf die Auslegung von Hängern, die durch Ermüdung infolge wirbelinduzierter Querschwingungen gefährdet sind, wird als stochastisches semi-infinites Optimierungsproblem formuliert. Zur Lösung dieses Problems sind mehrere Modellierungsebenen erforderlich, so dass ein Mehrebenenproblem entsteht. Es wird der derzeitige Entwicklungs- und Implementierungsstand bei der Umsetzung des Mehrebenenproblems in ein Entwurfsleitsystem (Software) aufgezeigt. Außerdem werden die Konzepte der noch ausstehenden Forschungsarbeit, die bereits erfolgreich beim lebensdauerorientierten Entwurf von Industriehallen mit Rahmensystem als Haupttragwerk eingesetzt wurden, diskutiert und ihre Einbildung in die bisher umgesetzte Forschungsarbeit erläutert.

The Concept of AI in Legal Tech: Automating Contract Review and Risk Detection
Creators: name: Researchscholar
Publisher: name: Zenodo

description: The legal industry is experiencing a digital transformation, and Artificial Intelligence (AI) stands at the forefront of this evolution. In particular, contract review and risk detection are being revolutionized by AI-powered tools that offer speed, consistency, and scalability beyond human capabilities. Traditional legal review processes are time-intensive and prone to human error, especially as contract complexity and volume continue to increase. This paper explores the application of AI in automating legal contract analysis, focusing on the foundational technologies of natural language processing, machine learning, and semantic analysis. It examines core use cases, including due diligence, regulatory compliance, and contract lifecycle management. Real-world applications by law firms and corporations are discussed to illustrate the effectiveness and limitations of AI-driven legal tools. Ethical and regulatory considerations surrounding confidentiality, accountability, and transparency are critically assessed. The paper also outlines the challenges of bias, model interpretability, and resistance within the legal profession. Finally, it looks to future innovations, including explainable AI, multilingual systems, and autonomous legal agents that will continue to reshape how legal work is performed.

description: Modellverwaltungssysteme sind eine geeignete technologische Basis zum Management digitaler Bauwerksmodelle bei Planungstätigkeiten für den Neubau als auch für die Revitalisierung von Bauwerken. Die Unterstützung von Revitalisierungsprozessen impliziert für den Entwurf integrierter Planungsumgebungen spezifische Anforderungen wie die Repräsentation von Informationen, die mit verschiedenen Typen von Vagheit behaftet sind, die Notwendigkeit, den Soll- sowie den Ist- Zustand des Bauwerks abzubilden und die Fähigkeit des Umgangs mit temporal inkonsistenten Modellzuständen. Die erforderliche Dynamik der Domänenmodelle und die erforderliche Nutzbarkeit in Virtual Enterprises stellen weitere Ansprüche an die Realisierungsbasis der Modellverwaltungssysteme. Zur Implementierung derartiger Systeme erweist es sich als vorteilhaft, Eigenschaften objektorientierter Programmiersprachen mit nichtstatischen Typsystemen auszunutzen, da diese durch die vorhandene Metaebene sowie Introspektions- und Reflektionsmechanismen eine effiziente Realisierungsbasis bereitstellen. Zur effektiven Unterstützung synchroner kooperativer Planungstätigkeiten innerhalb einzelner Fachdisziplinen wurde ein Benachrichtigungsmechanismus realisiert, der an das Modellverwaltungssystem angekoppelte Fachapplikationen über nebenläufig vorgenommene Modifikationen am zugehörigen Domänenmodell oder an Projektinformationen informiert. Weiterhin existiert ein Mechanismus zur vereinfachten Anbindung von existierenden Applikationen, die auf statischen Partialmodellen beruhen oder standardisierte, modellbasierte Austauschformate unterstützen. Abschließend wird eine aus einem zentralen Projektserver, Domänenservern und Domänenclients bestehende hybride Systemarchitektur vorgestellt, die geeignet ist, unter den Randbedingungen kooperativer und geographisch verteilter Arbeit bei Revitalisierungsvorhaben in Virtual Enterprises eingesetzt zu werden.

description: We give a summary of our results based on discrete Cauchy-Riemann operators in the plane. These operators are defined in a way that the factorization of the real Laplacian into two adjoint Cauchy-Riemann operators is possible. This property is similar to the continuous case and can especially be used for calculating the discrete fundamental solution of our finite difference operators. Based on the discrete fundamental solution we define a discrete operator that is right inverse to the discrete Cauchy-Riemann operator. In relation with this operator and an operator on the boundary we are able to prove a discrete version of the Borel-Pompeiu formula. In the second part we present a possibility to solve discrete Stokes and Navier-Stokes problems. The concept is based on the orthogonal decomposition of the space l2 into the space of discrete holomorphic functions and its orthogonal complement. By introducing the orthoprojectors P+h and Q+h we can prove the existence and uniqueness of the solution of discrete Stokes problems. In addition we state a problem that is equivalent to the discrete Navier-Stokes problem and can be used in an iteration procedure to describe the solution of this problem. For a special case of the Navier-Stokes equations we are able to calculate discrete potential and stream functions. The adapted model includes important algebraical properties and can immediately be used for numerical calculations. A numerical example is presented at the end of the article.
