Abstract The paper investigates the interaction of conceptual blending and conceptual metaphor in producing figurative creativity in discourse. The phenomenon of figurative creativity is defined by Kövecses (2005) as creativity arising through the cognitive mechanisms of metonymy, metaphor, and blending. Specifically, the paper examines the use of creative figurative language in the British public discourse on the topic on Brexit. The aim of this paper is to show that conventional metaphors can be creatively stretched through conceptual blending, producing instances of creative figurative language. Specifically, applying blending theory, we will analyse innovative conceptual blends, motivated by the conventional marriage/divorce metaphor. In addition, the paper also examines the way in which creative figurative language produced in metaphorical blends provides discourse coherence at intertextual and intratextual levels.

In this paper a method to control the output current of a three-phase grid connected two-level converter is presented. The current control approach is a finite control set model predictive control with sphere decoding. Sphere decoding algorithm gives a computationally efficient solution of the problem for long horizons. The goal of the control algorithm is to minimize the grid current tracking error and switching frequency. These goals are met with the choice of the appropriate cost function. Simulations are carried out in order to investigate the proposed current control approach. The influence of control parameters on the control objectives is investigated through simulations.
