About the project

Objective
The project aims to develop analysis and synergy mechanisms for complex systems consisting of high-order interactions, with a particular focus on opinion and societal-scale dynamics on hypernetworks. The ultimate goal is to apply the methodology and insight derived from collective behaviors of social dynamics on hypernetworks and moment-based approaches in societal-scale networked systems to design more efficient and sustainable infrastructures. These include transportation systems, smart grids, and smart buildings, where human decisions and group interactions are pivotal.

Background
In recent years, there has been a growing interest in studying the collective behavior of systems with higher-order interactions. The motivation stems from a practical need in real-world applications where the phenomena observed in complex systems cannot be adequately captured by considering only pairwise interactions between agents. Instead, these systems require the inclusion of higher-order interactions, often represented by hypergraphs or simplicial complexes. Such a need is evident in numerous applications, ranging from neuron dynamics to protein interaction networks, and from ecological systems to social systems. Understanding how these high-order interactions affect collective behaviors in social dynamics and incorporating their effects into human-involved infrastructures is greatly needed.

About the project

Objective
The project creates opportunities for a new form of public performances where the line between artists and audience is blurred. We work with mixed and augmented reality together with immersive participation and new mobile communication technology. We will demonstrate this in an interactive performance in a public environment.

The project aims at:

Background
We focus on the creation of a completely new form of public performances where physical actors can interact with virtual actors, and with physical and virtual objects. The project develops and studies both artistic creative processes and new wireless communication technology such as WiFi7 and 6G. We also use a number of prototypes developed in collaboration between Stockholm University and Ericsson Research during 2023–2024.

Central to the SECE project is the use of mixed reality (MR), enabling us to mix physical and virtual actors, objects and environments. The goal is to enable performances also outdoors, which is a big challenge with today’s technology.

The project involves expertise from many different directions and areas such as mobile communication, augmented and mixed reality, artistry and choreography.

About the project

Objective
A Lego-inspired design framework called SiLago (Silicon Lego) enables automation from the system level to ready-to-manufacture solutions for high-performance Edge AI applications. This framework bridges the gap between ease of use and performance by providing ASIC-comparable efficiency while achieving significantly improved energy efficiency—10X to 100X better than commercial off-the-shelf (COTS) solutions such as GPUs and FPGAs. The research project aims to enhance the SiLago framework to support comprehensive system-level implementation by addressing computation, storage, and interconnect requirements. These enhancements will enable SiLago to streamline the synthesis of complex applications, such as those required in industrial use cases. Finally, the improved system-level capabilities will be seamlessly integrated with the existing application-level synthesis flow, creating a unified, automated design process from applications to manufacturable silicon.

Background
The field of electronics and VLSI has driven transformative advancements in computing, enabling the development of increasingly powerful and efficient hardware systems. System architecture plays a crucial role in defining the structure and interaction of hardware components, ensuring efficient computation, storage, and communication. Despite these advancements, designing high-performance and energy-efficient hardware, such as ASICs, remains a complex, resource-intensive process requiring specialized expertise. The SiLago framework builds on these foundations, combining principles of VLSI, hardware modeling, system architecture, and design automation to provide a modular, automated solution for ASIC design.

About the project

Objective
To develop a mobile application that leverages advanced 3D pose estimation technology for tracking and analyzing a person’s movement outside traditional laboratory settings. This app aims to complement the clinician’s work by enabling remote monitoring and interaction between patients and healthcare providers, thus facilitating data-driven physiotherapy and rehabilitation sessions.

The benefits of such an approach include:

Background
The need for innovative tools that offer quantitative insights into patients’ movements has become increasingly apparent, particularly for remote or home-based physiotherapy and rehabilitation. Traditional methods often rely on in-person assessments that may not fully capture the nuances of a patient’s progress or challenges.

An app that provides accurate, quantitative movement analysis can significantly enhance the clinician’s ability to tailor treatments, monitor progress remotely, and ensure patients perform exercises correctly while reducing the need for frequent in-person visits.

Status
The current app demo utilizes a single smartphone or tablet to capture a person’s 3D movement using the device’s depth camera capabilities. To ensure high accuracy and reliability, the app employs a machine learning model to refine and improve pose estimation based on data collected from a wide range of users. The current implementation primarily targets the lower extremities, focusing on walking. Efforts are underway to broaden the model’s scope to encompass a broader range of movements.

About the project

Objective
The QB-ACT project aims to develop and evaluate an Internet-based psychological intervention integrating Question-Based Learning (QBL) and Acceptance and Commitment Therapy (ACT). It seeks to create an engaging, user-friendly platform for delivering therapy to improve mental health outcomes, reduce dropout rates, and enhance treatment adherence. By conducting a randomized controlled trial, the project will assess its effectiveness in addressing anxiety, depression, and overall well-being. Additionally, it aims to promote accessibility and scalability, providing an innovative alternative to traditional mental health care while supporting broader adoption through stakeholder dissemination and integration into healthcare systems.

Background
The QB-ACT project addresses critical challenges in mental health care: the growing demand for services and insufficient accessibility. Internet-based psychological interventions offer scalable solutions but often face issues like low engagement and high dropout rates. To overcome these barriers, the project integrates the evidence-based framework of Acceptance and Commitment Therapy (ACT) with Question-Based Learning (QBL), a proven methodology from e-learning. ACT fosters mindfulness and value-driven action to improve mental health, while QBL enhances engagement and learning through interactive, problem-solving techniques. By uniting these approaches, QB-ACT seeks to create a transformative digital platform, making therapy more accessible, personalized, and effective.

Crossdisciplinary collaboration
The proposed research project unites a multidisciplinary team with expertise spanning clinical psychology, Internet-based psychological treatments, large-scale e-learning technology, instructional design, online education, and the OLI Torus e-learning platform, ensuring a comprehensive and innovative approach to digital mental health interventions.

About the project

Objective
The project aims to develop a model-based decision-making tool for planning, designing and improving patient flows at the Karolinska University Hospital. The tool will include a prediction model, integrating clinical data, production data, and expert knowledge of the patient flows through the emergency department and the hospital. In addition, a network-based simulation model will be integrated to facilitate capacity and resource planning to improve patient care, decisions on handling and resource utilisation.

Background
Hospital emergency departments play a central role in healthcare systems and patient flow logistics throughout the system. Delivery of emergency care is resource and knowledge-intensive and requires close alignment with all other hospital functions and departments. Emergency healthcare is a complex system with high variability in patient characteristics, disease profile, processes and outcomes. This is a challenge for change work aimed at improving efficiency.

Little or no work has combined clinical and production data into process models to inform healthcare planning. Current models treat the emergency department as an independent leverage point without considering downstream bottlenecks in hospital wards. Overcoming these methodological limitations is important for informing hospital resource planning.

About the project

Objective
The EFFECT project aims to develop a digital twin of electrified construction site resources, processes, and their dependencies to evaluate the potential cost (efficiency) and benefit (emission reductions) of best-practice electrification of a construction site. Partners KTH, ABConnect, and Gordian, along with the City of Stockholm and 3rd parties PEAB and Northvolt, will use the digital twin to evaluate a construction site and, in a planned continuation project, optimize the steps of electrified construction operations using AI methods similar to those used in chess machines. The digital twin and its application will be developed and tested within the Kvarter Persika living lab, an urban renewal project of 1200 apartments in Södermalm, Stockholm.

Background
By 2050, the number of people living in cities will increase by 60% to 6.5 billion. City construction today is responsible for 23% of the global carbon emissions. Electrification is the de-facto technology for decarbonising our society, including city construction. However, due to the variability, non-linearity, and relatively long duration of new processes linked to electrification, we need more knowledge about the potential benefits and costs of electrified constructions and smart methods for planning and optimizing electrified construction operations.

Crossdisciplinary collaboration
In the EFFECT project, academia, research-based startups, the city and large industrial partners from the construction and energy industries will combine academic disciplines of control theory, simulation, optimization, AI/ML, and network communications to make future city construction more sustainable.
