- The objective of the present work was to develop a techno-economic system model to evaluate how logistics and production parameters affect the torrefaction supply chain costs under Swedish conditions. The model consists of four sub-models: (1) supply system, (2) a complete energy and mass balance of drying, torrefaction and densification, (3) investment and operating costs of a green field, stand-alone torrefaction pellet plant, and (4) distribution system to the gate of an end user. The results show that the torrefaction supply chain reaps significant economies of scale up to a plant size of about 150–200 kiloton dry substance per year (ktonDS/year), for which the total supply chain costs accounts to 31.8 euro per megawatt hour based on lower heating value (€/MWhLHV). Important parameters affecting total cost are amount of available biomass, biomass premium, logistics equipment, biomass moisture content, drying technology, torrefaction mass yield and torrefaction plant capital expenditures (CAPEX).

- Driving simulator studies can reveal relevant and valid aspects of driving behavior, but underestimation of distance and speed can negatively affect the driver's performance, such as in performance of overtaking. One possible explanation for the underestimation of distance and speed is that two-dimensional projection of the visual scene disrupts the monocular-based illusory depth because of conflicting binocular and monocular information of depth. A possible solution might involve the strengthening of the monocular information so that the binocular information becomes less potent.In the present study, we used an advanced high-fidelity driving simulator to investigate whether adding the visual depth information of motion parallax from head movement affects sense of presence, judgment of distance and speed, and performance measures coupled with overtaking. The simulations included two types of driving scenario in which one was urban and the other was rural. The main results show no effect of this head-movement produced motion parallax on sense of presence, head movement, time to collision, distance judgment, or speed judgment.However, the results show an effect on lateral positioning. When initiating the overtaking maneuver there is a lateral positioning farther away from the road center as effect of the motion parallax in both types of scenario, which can be interpreted as indicating use of naturally occurring information that change behavior at overtaking. Nevertheless, only showing tendencies of effects, absent is any clear additional impact of this motion parallax in the simulated driving.

- In outdoor robotics it is important to be able to ascertain the traversability of thes urrounding terrain. This paper presents a system where continuously generated traversability maps, useful for obstacle avoidance, are generated, stored and later reused to perform detailed local path planning. The detailed plan can be used as a temporary replacement for parts of a global plan that may lack knowledge about impassable obstacles or troublesome areas. The paper also describes an algorithm useful for on-line alignment and merging of previously stored traversability maps. Being able to align and merge maps is vital as the estimated global poses of multiple overlapping maps stored at different times may differ.

- As the adoption of Fifth Generation (5G) systems increases, efforts towards Sixth Generation (6G) systems have already started across research, standardization, and stakeholder fora. 6G is expected to support applications with immersive capabilities, with specific use case requirements from different verticals playing a critical role in solution development. Unlike current solutions in the education vertical that uses immersive technologies such as Augmented/Virtual/eXtended Reality (AR/VR/XR), which rely on pre-recorded content and lack engagement, 6G can enhance remote education by enabling real-time, AR/VR/XR-enriched interactions among students and instructors. This paper presents ongoing activities within the 6G-PATH EU project, towards the design, implementation, and testing of a 6G use case for healthcare personnel remote education/training, which aims to facilitate real-time, AR/VR/XR-enhanced interactions among healthcare trainees and instructors.
