Introducing Iterative Model Calibration (IMC) v1.0: A Generalizable Framework for Numerical Model Calibration with a CAESAR-Lisflood Case Study
Abstract. In geosciences, including hydrology and geomorphology, the reliance on numerical models necessitates the precise calibration of their parameters to effectively translate information from observed to unobserved settings. Traditional calibration techniques, however, are marked by poor generalizability, demanding significant manual labor for data preparation and the calibration process itself. Moreover, the utility of machine learning-based and data-driven approaches is curtailed by the requirement for the numerical model to be differentiable for optimization purposes, which challenges their generalizability across different models. Furthermore, the potential of freely available geomorphological data remains underexploited in existing methodologies. In response to these challenges, we introduce a generalizable framework for calibrating numerical models, with a particular focus on geomorphological models, named Iterative Model Calibration (IMC). This approach efficiently identifies the optimal set of parameters for a given numerical model through a strategy based on a Gaussian neighborhood algorithm. We demonstrate the efficacy of IMC by applying it to the calibration of the widely-used Landscape Evolution Model, CAESAR-Lisflood, achieving high precision. Once calibrated, this model is capable of generating geomorphic data for both retrospective and prospective analyses at various temporal resolutions, and retrospective and prospective analyses at various temporal resolutions, specifically tailored for scenarios such as gully catchment landscape evolution.

The paper introduces a novel approach for detecting structural damage in full-scale structures using surrogate models generated from incomplete modal data and deep neural networks (DNNs). A significant challenge in this field is the limited availability of measurement data for full-scale structures, which is addressed in this paper by generating data sets using a reduced finite element (FE) model constructed by SAP2000 software and the MATLAB programming loop. The surrogate models are trained using response data obtained from the monitored structure through a limited number of measurement devices. The proposed approach involves training a single surrogate model that can quickly predict the location and severity of damage for all potential scenarios. To achieve the most generalized surrogate model, the study explores different types of layers and hyperparameters of the training algorithm and employs state-of-the-art techniques to avoid overfitting and to accelerate the training process. The approach’s effectiveness, efficiency, and applicability are demonstrated by two numerical examples. The study also verifies the robustness of the proposed approach on data sets with sparse and noisy measured data. Overall, the proposed approach is a promising alternative to traditional approaches that rely on FE model updating and optimization algorithms, which can be computationally intensive. This approach also shows potential for broader applications in structural damage detection.

This paper is a case study of how a government software contractor might use models to define a process for designing and implementing a software product that complies with the documentation requirements. The intent of the paper is to apply business process modeling technology to the software engineering domain, thus exploring strengths and ...
In this paper, we present a review of the software process models commonly used in practice, from traditional to agile, and assessment of these models with metrics and case studies. The Waterfall ...
In contrast to software life cycle models, software process models often represent a networked sequence of activities, objects, transformations, and events that embody strategies for accomplishing software evolution. Such models can be used to develop more precise and formalized descriptions of software life cycle activities.

Software process models are not just a set of rules to follow; they are dynamic and adaptable to different project requirements. They provide a structured approach to software development, ensuring that all necessary steps are taken to deliver a successful product. When it comes to software development, there is no one-size-fits-all approach.
Abstract. The paper's specific concern is with software process modelling for the measurement of rework during application development using computer-aided software engineering (CASE) tools. In order to measure aspects of software development, one needs a defined process that models the aspects of interest. The goals of this study are rather ...

Abstract. The topic of this full-day tutorial was the correct use and interpretation of case studies as an empirical research method. Using an equal blend of lecture and discussion, it gave attendees a foundation for conducting, reviewing, and reading case studies. There were lessons for software engineers as researchers who conduct and report ...
The input and output of each task. The pre and post-conditions for each task. The flow and sequence of each task. The goal of a software process model is to provide guidance for controlling and coordinating the tasks to achieve the end product and objectives as effectively as possible. Source: Omar Elgabry.
A software process improvement method can be used to support the implementation of a key process area (KPA) of the Capability Maturity Model (CMM) or to improve the effectiveness of key practices within a KPA. "* Fewer product defects found by customers. "* Earlier identification and correction of defects.
1.. IntroductionProcess modelling techniques are widely used in both business and academic organisations where research on process modelling or workflow management has been conducted for several years ([25], [13] or [4]).Process modelling requires workflow models, along with techniques for capturing and describing processes [18], with activity-based workflow modelling (in which a workflow ...

Use cases are a tool for modeling requirements. A set of use cases can provide a framework for the requirements specification. Use cases are the basis for system and program design, but are often hard to translate into class models. This restaurant example is based on a use case diagram from Wikipedia.
Based on their own experiences of in-depth case studies of software projects in international corporations, in this bookthe authors present detailed practical guidelines on the preparation, conduct, design and reporting of case studies of software engineering. This is the first software engineering specific book on thecase study research method.

This paper describes a case study designed to assess the potential of using process mining techniques to provide visibility into the deployment pipeline, namely core DevOps metrics such as lead time. The object of the study concerns the continuous development practices of six engineering teams from a major European e-commerce company.
Software engineering (SE) activities have been revolutionized by the advent of pre-trained models (PTMs), defined as large machine learning (ML) models that can be fine-tuned to perform specific SE tasks. However, users with limited expertise may need help to select the appropriate model for their current task. To tackle the issue, the Hugging Face (HF) platform simplifies the use of PTMs by ...
Abstract. In geosciences, including hydrology and geomorphology, the reliance on numerical models necessitates the precise calibration of their parameters to effectively translate information from observed to unobserved settings. Traditional calibration techniques, however, are marked by poor generalizability, demanding significant manual labor for data preparation and the calibration process ...

We will specifically focus on representation concepts and categories of diagrams for business process modelling. However, readers will find below a brief summary of the three techniques in terms of coverage, richness of representation, and ease of use: -. The main focus of ADONIS is on business process modelling; the graphical notation is very ...
The paper introduces a novel approach for detecting structural damage in full-scale structures using surrogate models generated from incomplete modal data and deep neural networks (DNNs). A significant challenge in this field is the limited availability of measurement data for full-scale structures, which is addressed in this paper by generating data sets using a reduced finite element (FE ...
1. Introduction. Case studies are common in software engineering, and guidelines have been provided, for example, byRuneson et al.
