Mitigating Health Inequalities – A Transdisciplinary System Thinking Approach – Nadeem Abbas
Health inequalities persist and have increased in some Swedish regions. Considering the multifaceted nature of this problem the new national public health policy emphasizes shared responsibility and coordinated efforts at all levels. To this end, Nadeem will present preliminary results of a project that aims to identify and investigate factors that are leading to the problem of health inequalities in the Kronoberg region, and how digital technologies can help to mitigate such inequalities. The project follows a transdisciplinary approach involving researchers from various disciplines and practitioners in the field, to identify and analyze factors, barriers and unmet needs leading to the health inequalities. The project focusses on Araby area of Kronoberg. The data is collected through meetings and semi-structured interviews with relevant stakeholders working in the area. Preliminary analysis indicates following major factors causing health inequalities in the region: 1) language and cultural barriers, 2) lack of knowledge about the health care system, and 3) complexity of the existing system. Furthermore, the analysis shows that there is need for improving health literacy, particularly, in vulnerable groups, such as migrants. The project work is still in progress and Nadeem will discuss future plans and possibilities to collaborate with interested researchers.

Antifragility and resilience in ICT systems – Diego Perez
Antifragility is a term that has recently emerged to refer to ICT systems that remain trustworthy despite their dynamic and evolving operating context. This talk will present a characterization of antifragility for ICT systems, aiming to clarify the implications of its adoption, its relationships with other approaches sharing a similar objective, and a possible guide to engineer antifragile computing systems. To provide a background for reasoning on antifragility, the talk will first introduce a framework for dependability and resilience properties and then it will relate them to antifragility.

Title: Realizing Smarter Organizations through Digital Twin of the Organization Approach

Abstract:
To survive and remain competitive in today’s dynamic, uncertain, and constantly changing environment, organizations must alter their traditional business software solution and be smarter. A smarter organization needs smarter machinery systems. These systems can be categorized into four levels of smartness based on their ability to adapt at runtime. Self-adaptive systems (SAS), enabling run-time adaptation, play a crucial role in achieving different levels of system smartness where they autonomously adjust their behavior in response to changes in the environment, system conditions, or system goals. Although various waves of research on engineering SAS pave the way toward smarter systems, several issues like changing adaptation goals at run time, keeping run time models up-to-date, complex nature of uncertainty, etc. have remained open, yet. To overcome these issues, our solution is adding a digital twin as an additional specialized component to modify the managing system of SAS over time.
Despite the contribution of smarter systems to the efficiency and effectiveness of an organization, it is not the ultimate goal of smarter organizations. Becoming a smarter organization requires a holistic approach considering smart machinery systems, processes, people, culture, and strategy. Therefore, developing methodologies to facilitate managing, controlling, and evolving the organization as well as dealing with its complexity is crucial. Digital Twin of the Organization (DTO) provides a suitable basis for continuous assessment, optimization, and prediction by representing all the organizational system elements and connections in virtual models and through perpetual simulation and analysis. However, creating a flexible and evolvable DTO that covers and supports the organization’s business strategies is a complex and time-consuming task that requires engineering best practices. As our proposal, EA Blueprint Pattern serves as an architectural reference for the development and evolution of a DTO by allowing for mapping well-known Enterprise Architecture concepts into software components defining the DTO software architecture.

ChatGPT as a combined OCR and key-value extractor – Nemi Pelgrom, Industry PhD student at Fortnox

This study presents the results of an experiment of using the AI chatbot chatGPT as a combined OCR and key-value extractor. The dataset used consisted of 1000 real invoices and 500 images of real receipts from a wide variety of Swedish market sectors. This tool demonstrated an accuracy rate of 99.8% in extracting key financial data from invoices, and 100% accuracy from images of receipts, showcasing its potential as a one-stop solution for financial document processing.

Data-Driven Approach Towards Objective Evaluation of the Gravel Road Condition – Keegan Mbiyana, PhD-student in Mechanical Engineering

Visual windshield surveys are the primary method for assessing the condition of gravel roads, but they can be prone to human judgment errors and can be time-consuming. There is a need to shift to an objective assessment of the condition of gravel roads by leveraging advances in sensor technology and data processing techniques for efficiency and effectiveness. This seminar will present work conducted in the Department of Mechanical Engineering in objectively assessing the gravel road condition to improve maintenance planning and decision-making. The results from the field experiments on three gravel roads with different condition classes and the vehicle vibration response collected using Integrated Electronics Piezo-Electric (IEPE) and smartphone accelerometers to verify a proposed rule-based approach will be presented. The challenge of regular monitoring is discussed, considering the remote location of gravel roads. Regular condition monitoring and data collection would require collecting and storing huge amounts of data. Therefore, as part of future work, the seminar will briefly introduce an adaptive sampling technique to reduce redundant or unnecessary data before storage.

Abstract

Bridging temporal gaps in vegetation indices satellite data and forecasting the future – Tibo Bruneel, PhD student at Softwerk AB
In this research seminar I will present the machine learning work I have done so far in my PhD studies with some intermediate results. The research addresses the challenge of inconsistent temporal data gaps in Sentinel-2 vegetation indices time series and the forecasting of the vegetation index future.

Temporal data gaps occur in sentinel-2 optical data, mostly arising from factors such as cloud cover and adverse weather conditions. Having very inconsistent time series prevents further analysis such as detection, quality control and forecasting. Therefore we first address the data continuity challenge to obtain a consistent daily estimation of the vegetation index.

Given a consistent timeline of daily estimates, we further attempt to predict the near future of the vegetation index. Here we attempt to achieve both a high forecasting accuracy, and a strong generalisability over different locations in the world, as models trained on a single location often are hard to generalise on different environments.
