In this paper, a precoding scheme for interference mitigation based only on local channel state information is proposed for downlink multicell multiantenna systems with joint transmission. The investigated scheme places interference components at the receivers coming from the different transmitters in predefined subspaces, so that they are completely or approximately cancelled. It is shown how ...

Power generation and distribution remains an important topic of discussion since the industrial revolution. As the system continues to grow, it needs to evolve both in infrastructure, robustness and its resilience to deal with failures. One such potential failure that we target in this work is the cascading failure. This avalanche effect propagates through the network and we study this propagat...

Automating malware mitigation requires taking into account potentially intricate dependencies among the system’s components, understanding potential side-effects of the possible actions, and ensuring that required system functionalities are preserved. Answers still need to be found for fundamental questions: What does it mean to mitigate malware? When can one claim that malware has been mitigat...

The land-use sector can contribute to climate change mitigation not only by reducing greenhouse gas (GHG) emissions, but also by increasing carbon uptake from the atmosphere and thereby creating negative CO2 emissions. In this paper, we investigate two land-based climate change mitigation strategies for carbon removal: (1) afforestation and (2) bioenergy in combination with carbon capture and s...

In this article, we report on a serious game development approach, characterized by combining theory-based design with an iterative development strategy guided by experimental test and evaluation. We describe two serious games that teach the mitigation of cognitive biases (human tendencies to commit systematic errors in thinking that lead to irrational judgments). Cognitive biases tend to be de...

In dealing with climate change, how much should governments focus their effort on mitigation (emission reduction to prevent climate change) and on adaptation (coping with a changed climate)? Very little research has gone into pinning down which strategy is dynamically optimal under what kind of conditions. This paper contributes to this debate by developing a parsimonious optimal control model ...

In Sweden, where forests cover more than 60% of the land area, silviculture and the use of forest products by industry and society play crucial roles in the national carbon balance. A scientific challenge is to understand how different forest management and wood use strategies can best contribute to climate change mitigation benefits. This study uses a set of models to analyze the effects of di...

A hidden failure embedded DC model of power transmission systems has been developed to study the power law distributions observed in North American blackout data. We investigate the impacts of several model parameters on the global dynamics and evaluate possible mitigation measures. The main parameters include system loading level, hidden failure probability, spinning reserve capacity and contr...
