Reduced-Cost Microwave Design Closure by Multi-Resolution EM Simulations and Knowledge-Based Model Management
PublicationParameter adjustment through numerical optimization has become a commonplace of contemporary microwave engineering. Although circuit theory methods are ubiquitous in the development of microwave components, the initial designs obtained with such tools have to be further tuned to improve the system performance. This is particularly pertinent to miniaturized structures, where the cross-coupling effects cannot be adequately accounted...

Non-places in the centre of the historic Main Town in Gdansk? – Design Thinking as a method of solving problems in cities
PublicationThe interiors of reconstructed extensive blocks of the historic Main Town in Gdansk are nowadays degraded areas, full of cars, with “holes” after never-finished archaeological excavations. It is not surprising that inhabitants avoid them. These are NON-PLACES. This situation prompts social movements to act. The first step towards the change was the interdisciplinary and transdisciplinary project of revitalization of one of the...

Can Grand Design Doctrines Go Well with Locally Reinvented Urbanisms? Notes from Polish Cities in Transition
PublicationThe text explores how New Urbanism ideas, a comprehensive global design doctrine, transgress into the context of Polish planning practice. New Urbanism is considered through the perspective of the decentralization of a discussion on a planning policy and a modernization of a State, resulting form its post-Socialist urban change. In the text, New Urbanism is understood as a neotraditionalist movement i.e. drawing from the pre-modernist...
