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.

Title: “Using ML/RL to develop visual and tactile sensing for the next generation of assistant devices and smart prosthesis”

Abstract:
The next generation of autonomous robotic assistants and semi-autonomous prostheses will focus on making object manipulation more predictable and reliable. Achieving these goals requires novel manipulation methods while obtaining and processing accurate object information. This presentation delves into recent investigations leveraging Machine Learning models and Reinforcement Learning methodologies to extract hand and object characteristics from visual and tactile data. Our ongoing research spans various domains, including robotic perception, human grasp analysis, and intention recognition. Specifically, we will showcase progress in haptic feedback integration, enhancing robot hand grasp stability, automatic texture recognition, precise surface reconstruction, and optimizing robotic disassembly tasks. Through these endeavors, we aim to illuminate pioneering approaches in employing machine learning models to analyze visual-tactile data, offering promising applications in automated hand control and biomedical engineering.

Advancements in IoT and AI Integration: Insights from Kalmar’s IoT Lab – Fredrik Ahlgren
In this seminar, Dr. Fredrik Ahlgren, Senior Lecturer at Linnaeus University, will outline the transformative journey of establishing the IoT Lab in Kalmar, showcasing its evolution from an initial concept to a thriving research hub. The presentation will highlight the lab’s innovative projects, such as connected beehives and the M/S Dessi connected ship initiative, alongside collaborative efforts with over 15 industry partners through pilot cases. Dr. Ahlgren will delve into the integration of AI for data analysis, including the use of ChatGPT for enhancing research outputs. The seminar will reference specific publications, such as the application of machine learning for fuel consumption prediction in maritime engineering and the use of reinforcement learning in IoT environments, underscoring the lab’s contribution to applied research in IoT and AI. Attendees will gain insights into the lab’s strategic approach to leveraging IoT and AI for addressing real-world challenges, highlighting the impact of these technologies on industry and education.

Data and sustainability – Jorge Zapico
Data can make sustainability issues visible and actionable: carbon emissions, biodiversity, energy, resource consumption, waste. These issues are complex, long term, systemic, and we have problems grasping them without support. Technology provides new ways to measure the current state, simulate future scenarios and options, and to get feedback about ongoing changes and interventions. Dr. Jorge Zapico, Senior Lecturer at Linnaeus University will present lesson learnt from developing prototypes and services for sustainability during the last 15 years, what he sees as the main contributions, risks and pitfalls, and which future innovation spaces lay ahead.

The 8th International Workshop on Formal Approaches for Advanced Computing Systems (FAACS 2024), co-located with the 21st IEEE International Conference on Software Architecture (ICSA 2024), will be held in IIIT Hyderabad, India June 4-8, 2024.

Important Dates:
– Submission Deadline: February 18, 2024
– Notification of Papers: March 17, 2024
– Camera Ready: March 31, 2024
– Workshop Date: June 4 – 5, 2024

Motivation and Scope
Cutting-edge technologies, infrastructures, and computational paradigms such as digital twin, cloud, fog, edge computing, IoT, digitalization, Industry 5.0, and cyber-physical systems are changing how data and services are delivered and used. Such systems have a significant and elaborate societal impact, making it paramount to guarantee essential qualities of the delivered product, such as dependability, reliability, safety, and availability. As new paradigms become pervasive in our everyday lives, new challenges also emerge in dealing with uncertainty, untrustworthiness, and information loss, affecting the software life cycle in different phases. Ensuring critical qualities requires a joint effort in devising advanced software architecture designs by the software architecture community and formal modeling and verification approaches by the formal methods community.

The main goal of the workshop is to foster integration between formal methods and software architecture promoting new connections and synergies between the two communities to address the challenges of the upcoming generation of computing systems. Aligned with the theme of the ICSA 2024, we welcome contributions on the potential and risks of generative AI in developing advanced software architectures and ensuring qualities like dependability, reliability, safety, and availability through formal modeling and verification.

Topics of Interest include (but are not limited to) the following:

Using Virtual Reality to gain insights – Aris Alissandrakis

This seminar will give a brief overview of recent work (2017-now) conducted by the VRxAR Labs research group.

The evolution of our immersive analytics system that went from “simple” data exploration to supporting hybrid asymmetric collaboration will be presented.
The focus will be on the motivations and decisions that informed the direction of this research, and the methodological approaches used to make sure that the system both a) did what it was supposed to and b) was perceived favorably by its users.

Given that VR is better experienced and understood by seen in motion, anyone interested in this is encouraged to check out our video demonstrations on [https://vimeo.com/vrxar].

Cloud and HPC – Morgan Ericsson

We’ll start by discussing what HPC, Cloud computing and related terms mean. We’ll then discuss how and when you should use a cloud environment, such as CSCloud, for HPC. The talk will illustrate the important concepts using CSCloud and discuss, e.g., virtual machines and networks, containers, orchestration, etc.

Virtual Ecosystems for Smart Sustainable City-districts – an architecture perspective – Jesper Andersson

This talk will discuss architectural issues concerning establishing and operating a digital ecosystem. Digital ecosystems are becoming a foundation for value streams in multiple businesses and domains. The case we study is a smart-district platform, which shares challenges with the Smart-city.

This talk focuses on two concerns, the ecosystem’s platform architecture and architecture barriers to establishing and operating an ecosystem. We characterize sustainable product and service ecosystems in a smart-district ecosystem and discuss specific design alternatives. In a design process, certain architectural barriers impede ecosystem establishment and operation. We describe some categories with concrete examples from the case. In connection to the barriers, we describe specific architectural governance challenges and discuss some possible solutions. We discuss several avenues for future platform architecture and governance research.

Self-adaptation: basic principles and industrial usage – Danny Weyns
 
Self-adaptation enables a software system to reason about itself at runtime and adapt itself to realise a set of quality goals. Self-adaptation has been widely used in the software industry, but not necessarily known under the term self-adaptation. In this talk, I motivate the use of self-adaptation, outline the basic principles of self-adaptation, and report the results of a large-scale survey with practitioners on the use of self-adaptation in industry.
