It is well known that the water-wave problem with weak surface tension has small-amplitude line solitary-wave solutions which to leading order are described by the nonlinear Schrödinger equation. The present paper contains an existence theory for three-dimensional periodically modulated solitary-wave solutions which have a solitary-wave profile in the direction of propagation and are periodic in t
The legislated goals for Master of Science in Engineering educations include goals like having the ability to critically, independently and creatively identify, formulate and handle complex problems as well as participate in research and development work and thus contribute to knowledge development. One might therefore argue that these educations are required to promote a deep approach to learning
When low calorific value gases are fired, the performance and stability of gas turbines may deteriorate due to a large amount of inertballast and changes in working fluid properties. Since it is rather rare to have custom-built gas turbines for low lower heating value (LHV) operation, the engine will be forced to operate outside its design envelope. This, in turn, poses limitations to usable fuel
There is no alternative! Margaret Thatcher once proclaimed in order to defend neoliberalist reforms and – implicitly – the capitalist regime. But if one doesn’t agree with Thatcher’s definition of the situation and her (and her many followers’) subsequent analysis, what viable options does one really have? Is it possible to come up with an empirically grounded alternative to the dominant modes of
The chapter examines what peace looks like from the working levels of the Nordic countries. Several researchers have proclaimed a common Nordic approach to peace and conflict resolution “dead”. However, through interviews focusing on the working level, we find that the Nordics in fact work very closely together in practice, especially in the field in conflict-affected areas. This work is generally
The rise of social media platforms in the early 2010’s marked a shift in public diplomacy practice resulting in the emergence of “digital public diplomacy.” This chapter explores the evolution of digital public diplomacy by emphasizing digital culture as a significant source of social and political change in a broader societization of diplomacy. Moving beyond a narrow focus on digitalization, it a
