The division of Electrical Power and Energy Systems is now looking to hire two postdoc’s in grid-interactive power electronics systems, for employment at the School of Electrical Engineering and Computer Science. Power electronics has become a foundational technology for decarbonizing the global energy systems. The past years have witnessed massive integration of power electronic converters in electric power grids. Grid-interactive power electronic systems are commonly found in renewable-energy power generations, DC transmission systems, energy-efficient motor drives, electric-vehicle charging stations, power-to-x conversions, and other emerging grid infrastructure. This mega trend poses unprecedented challenges to the stability, security, and power quality of modern power and energy systems.

We are looking for a person to drive the work within the research theme Data-driven insights through simulation in the HITS2 project, which is a collaboration with Scania, the City of Stockholm and more than ten other partners. The project’s vision is to understand and create the conditions for a sustainable transport system in the city. The tasks consist of simulating and analyzing scenarios with different network solutions and placements of hubs, with a focus on a number of research questions: How can simulation demonstrate efficiency gains in consolidation and different distribution scenarios for logistics flows? What is an appropriate approach to simulate the above under various operational scenarios? Can the simulation tools support charging infrastructure decisions, and which aspects of the charging infrastructure are most relevant?

The Department of Energy Technology has strong research competence in heat pumping and refrigeration technologies with up-to-date laboratory infrastructure. The main objective in this project is to experimentally investigate and evaluate features to maximize the energy efficiency of CO2 vapor compression systems.

The research group Power System Planning and Electricity Markets at KTH is participating in several national and international research projects which aim to design the carbon dioxide-free power and energy system of the the future. To study these issues it is necessary to have energy system models that can mange large and complex systems. An example of such a model is Spine, which has been developed in an EU project, where KTH has participated. Spine is an open-source software, which can be used for simulating a wide range of energy systems.

The goal of this project is to develop models for prediction of aircraft emissions and noise. The model for aircraft emissions computation used within our research group is the Boeing fuel flow method 2 which should be adapted to also consider sustainable aviation fuels (SAFs) at different blending ratios. A model for particulate matter should also be developed. In addition, a model for aircraft noise will be implemented based on the aircraft noise numerical code SAFT which covers several methods for aircraft noise mapping, from an ECAC Doc 29 implementation to more advanced simulation methods.  Both environmental models should be suitable to compute noise and emissions (for fossil fuels and SAFs) along a given aircraft trajectory and for a given aircraft model. The researcher will also have to interact with other related projects dealing with aircraft trajectory optimization, climate impact and air quality which will be based on the mentioned environmental tool. Furthermore, he/she will have the opportunity to be involved in the KTH Centre for Sustainable Aviation (CSA). 

The work focuses on research in how organizations focus on sustainability and which management and control mechanisms can be used for industrial transformation. The work includes both qualitative and quantitative methods and methods for several different levels, such as individual, organization and industry. The focus is on both established organizations and new start-ups.

The successful candidate will focus on digital twin for human-robot collaborative assembly, including modelling and prediction for active collision avoidance, robot control, and software-hardware integration. The aim is to implement a safe and shared environment for human-robot collaboration at IPU Robotic Lab. Efforts will also be devoted to develop a digital twin platform for monitoring and control of robots.

We look for up to two postdocs to join the WASP NEST project PerCorSo: Perceiving and Communicating Correct-by-design Socially Acceptable Autonomous Systems. The job will entail:

• research, development and evaluation of autonomous motion strategies to advance real-world social robots;
• collaboration with researchers, who focus on perception, multi-modal interaction, and robot integration towards meeting the goals of PerCorSo.

You will be encouraged, but not required to teach master-level and PhD-level classes in the areas of safe autonomy and/or social robotics as well as to supervise master students.

The positions focus on research in (applied) algebraic geometry, discrete geometry, algebraic statistics, and/or causality. Of particular interest are questions related to homological invariants of algebraic data sets, algebraic and geometric properties of statistical models (including graphical models and neural networks), combinatorial and metric properties of polytopes related to statistical models, algebraic and geometric methods for computer vision, statistical learning and causality.

As a researcher, you will participate in the development and implementation of projects in the area of ​​production management for sustainability, at the Department of Production Engineering, at KTH Södertälje. More specifically, work is included in projects with a special focus on industrialization and upscaling of new products, as well as in development and operation of circular and sustainable production systems. The production management perspective is important, both operative and strategic. You will participate in projects such as the new research project “Green design”, participate in collaborative projects with industrial partners and other research groups, and disseminate research through research publications, conferences, seminars, digital media, industrial workshops, etc. You will also participate in gathering and communicating research results and new knowledge for industrial application. Generally, you will also contribute to the development of the department and the research group within Production Management, contribute to KTH’s Industrial Transformation platform and be active in teaching on bachelor level, advanced level and to some extent within production-related courses for industry representatives

In line with KTH’s goal of a future sustainable society, this effort is aimed at the sustainable goals of Clean and Affordable Energy and Climate Action, especially by enabling negative emissions through the capture of biogenic CO2. It is an important milestone towards a climate-neutral society. The technology used for BeCCS is established and available. Nevertheless, it is costly and innovations are expected to accelerate the implementation of new BeCCS features. In this project, we will increase the understanding of the relevant mechanisms and simulate turbulent heat and mass transport relevant to CO2 capture by droplets. This project mainly focuses on simulations with DNS.

Nanomaterials from cellulose in the form of cellulose nanofibrils (CNFs) or cellulose nanocrystals (CNCs), are today used to manufacture self-assembling materials with fantastic optical and mechanical properties. To optimize and control the properties of these materials, it is necessary to understand and control the colloidal interaction between these nanomaterials. Experimentally, there is today a large amount of results available concerning the self-organization of nanocelluloses, but no reliable theoretical models to describe this. It is therefore necessary to develop a more realistic theoretical model to describe the colloidal stability of dispersions of CNFs. To accomplish this, it is necessary to combine high-resolution experimental techniques with a theoretical model building. In the project, you will work independently using different types of CNFs (chemically/physically modified) and with characterizing their colloidal properties with new and established methods to clarify how the properties will change with changes in the chemical and/or physical environment. In order to link the experimental and theoretical work, you are expected to form a contact network where different basic skills can be used. This can of course be carried out through digital meetings but you are also expected to visit potential partners to explain the complexity of the subject and to explain why this is theoretically and practically interesting.
