Airport is a highly dynamic environment, turning emergencies into extensively costly and disruptive events with cascaded effects that will adversely affect the entire aviation system. Airports' management and safety divisions exercise precise and case-based procedures to accommodate any possible emergency scenarios. With this regards, airport emergencies have a number of challenges that require better and more adaptive way of addressing. Challenges such as lack of adaptive and customizable simulation-based decision support tools, infeasibility of conducting frequent physical emergency exercises, and the time-critical nature of emergencies in general raise an immediate need for a technology that collaboratively performs modeling, simulation, and visualization to guide first responders throughout the decision-making process. Here we propose a collaborative emergency modeling, simulation and analysis software system that provides an all-in-one simulation technology for enhancing emergency response at airports. © 2014 DIME UNIVERSITÀ DI GENOVA.

Recently there has been a rapid increase in the advancements and use of Small Unmanned Aerial systems (sUAS) for a wide range of applications ranging from precision agriculture, to environmental monitoring, and to the delivery of commercial products from logistic companies. Fixed wing, vertical takeoff-landing (FW-VTOL) sUAS offer significant usability and safety advantages over its rival systems. During emergencies, frequent transportation and delivery of medical materials, such as blood derivatives, among hospitals, and to mass causality scenes and offshore vessels are needed. This research considers sUAS logistics supply networks to all end locations within a 40 nautical miles radius, based from a central hub location. Units of medical materials will be continuously distributed outwards and return with emergency location samples. The optimization of this sUAS logistics supply model is based on transporting the most number of units between the hub and network nodes at the lowest cost of deployment and the shortest amount of time. At a first stage, the optimization model will include only one node of the network per flight, constraint to be relaxed at a second iteration where two or more nodes could be visited per each flight. © 2019 IISE Annual Conference and Expo 2019.

During recent years, we have seen many technological advancements which help to take better care of patient's health and assure them fast and safe recovery. The most basic item necessary is competent patient care in hospitals, as well as proper management of fluid and electrolytes. In hospital almost all patients, mainly ICU patients, have to regulate the volume of fluids and electrolyte into the bloodstream 247 which is done using drip. These drips need regular monitoring or changing to maintain constant flow of fluids or to prevent any infection to patients. Though this system is simple, overcrowded hospitals and the risk of deficiency of nurses can put patients at health risk which can deteriorate patients' health more aggressively or in worse case it can lead to death. Almost in all hospitals, nurses or the hospital staff are responsible for monitoring the drip level. But unfortunately, because of their hectic schedule, the observer may forget to change the bottle at the appropriate time. During the pandemic, hospitals were overrun with patients, and nurses were unable to do manual regular checks on the drip conditions and drip level of every patient, even after working extra shifts. Many patients even died due to not being able to get proper care from nurses. The next step in providing more effective and easy healthcare is to automate such vital procedures. To overcome this critical situation, we are proposing an IoT (Internet of Things) based Drip Monitor System using Arduino UNO which eases the process of measuring and solves the issues of bubble formation in drips. © 2022 IEEE.

Context: Model-driven code generation is being increasingly applied to enhance software development from perspectives of maintainability, extensibility and reusability. However, aspect-oriented code generation from models is an area that is currently underdeveloped. Objective: In this study we provide a survey of existing research on aspect-oriented modeling and code generation to discover current work and identify needs for future research. Method: A systematic mapping study was performed to find relevant studies. Classification schemes have been defined and the 65 selected primary studies have been classified on the basis of research focus, contribution type and research type. Results: The papers of solution proposal research type are in a majority. All together aspect-oriented modeling appears being the most focused area divided into modeling notations and process (36%) and model composition and interaction management (26%). The majority of contributions are methods. Conclusion: Aspect-oriented modeling and composition mechanisms have been significantly discussed in existing literature while more research is needed in the area of model-driven code generation. Furthermore, we have observed that previous research has frequently focused on proposing solutions and thus there is need for research that validates and evaluates the existing proposals in order to provide firm foundations for aspect-oriented model-driven code generation. © 2012 Elsevier B.V.

Neural generative modelling of sketches has been an active research direction. SketchRNN set a milestone with their sequence-to-sequence variational autoencoder architecture being able to generate hand drawn sketches in various classes by modelling them as sequences of displacements between consecutive stroke points. The diversity and variety in the set of handwritten Chinese characters makes them a good candidate for such generative modelling enabling their unconditional generation. However, modelling them as sequences of points causes coarse looking strokes and much longer sequences, consequently requiring use of polygonal approximation algorithms to cut down on points. Instead, we propose and investigate the modelling of Chinese characters as sequences of Bézier curves using the SketchRNN architecture with a few modifications, to allow the model to directly generate smooth curves. This way the encoded representation is smaller while more of the stroke's characteristics are retained and the generated characters are truly scalable. We also suggest the appropriate preprocessing strategy for the KanjiVG dataset to make it suitable for this purpose. Qualitative evaluation of the results suggests the model demonstrates generation of characters with mostly well-structured and ordered strokes. This was substantiated by quantitative evaluation based on the FrFréchetchet Inception Distance score. © 2023 IEEE.

Heart disease remains a leading cause of mortality and morbidity worldwide, necessitating the development of accurate and reliable predictive models to facilitate early detection and intervention. While state of the art work has focused on various machine learning approaches for predicting heart disease, but they could not able to achieve remarkable accuracy. In response to this need, we applied nine machine learning algorithms XGBoost, logistic regression, decision tree, random forest, k-nearest neighbors (KNN), support vector machine (SVM), gaussian naïve bayes (NB gaussian), adaptive boosting, and linear regression to predict heart disease based on a range of physiological indicators. Our approach involved feature selection techniques to identify the most relevant predictors, aimed at refining the models to enhance both performance and interpretability. The models were trained, incorporating processes such as grid search hyperparameter tuning, and cross-validation to minimize overfitting. Additionally, we have developed a novel voting system with feature selection techniques to advance heart disease classification. Furthermore, we have evaluated the models using key performance metrics including accuracy, precision, recall, F1-score, and the area under the receiver operating characteristic curve (ROC AUC). Among the models, XGBoost demonstrated exceptional performance, achieving 99% accuracy, precision, F1-Score, 98% recall, and 100% ROC AUC. This study offers a promising approach to early heart disease diagnosis and preventive healthcare. © 2025, CC BY.

Automatically detecting and visualising errors in UML diagrams

UML has become the de facto standard for object-oriented modelling. Currently, UML comprises several different notations with no formal semantics attached to the individual diagrams or their integration, thus preventing rigorous analysis of the diagrams. Previously, we developed a formalisation framework that attaches formal semantics to a subset of UML diagrams used to model embedded systems. This paper describes automated structural and behavioural analyses applicable to UML diagrams using our formalisation framework. In addition to intra- and inter-diagram consistency checks, we discuss how simulation and model checking can be used in tandem for behavioural analysis of the UML diagrams. Our tools also visually interpret the analysis results in terms of the original UML diagrams, thereby facilitating their correction and refinement. We illustrate these capabilities through the modelling and analysis of UML diagrams for an automotive industrial case study. © 2002 Springer-Verlag London Limited.
