Both current and historical settlement forms experience evolutionary, permanent changes to their spatial and socio-economic attributes, not seldom accompanied by dynamic functional transformations. The linkage between functionalism and dynamism, in turn, is one of those elements of conventional geographical theory used to explain the phenomena of urbanization and urbification. While urbanization r

Degraded and restituted towns constitute an important element of the contemporary settlement system in Poland. This significance stems from two basic facts: firstly, the relatively large number of such places, and, secondly, the role of restituted towns within the formal-legal dimension of urbanization. The importance of degraded and restituted towns is also shown in the variety of topics undertak

The large number of degraded (828) and restituted (240) towns in Poland formed the basis for crafting a chapter on the spatial and temporal distribution of these special settlement forms. By focusing on these two aspects has helped, for one, uncover historical regularities, and, for another, reveal geographical patterns of national urbanization processes. This is largely due to the fact that degra

This scientific note aims to briefly introduce the concept of urban hibernation, published recently (September 2015) in an article with the same name in European Planning Studies (Routledge). By outlining some general characteristics, the purpose of this note is merely to put the reader’s attention to this concept, whom we remit to the original article for a comprehensive walk-through. The reason

Public procurement is widely used in order to incorporate competition into public services. Competition in procurement often leads to efficiency but the process can also raise some problems. While providing the procurement documents you do not know who will be your upcoming partner. Another aspect is how flexibility can be managed in contract design while maintaining a high service quality. The ai

In high-income countries, parental age at first birth has increased and this postponement increases the risk of involuntary childlessness or having fewer children than desired. This interview study was conducted in Denmark and Sweden among childless men (n = 29) in their last year of an education. The aim was to explore the role of individual and societal factors on fertility decision-making and m

In this work, compliant mechanisms are designed by using multi-objective topology optimization, where maximization of the output displacement and minimization of the strain are considered simultaneously. To quantify the strain, we consider typical measures of strain, which are based on the p-norm, and a new class of strain quantifying functions, which are based on the variance of the strain. The t

Efficient mitigation of power amplifier (PA) nonlinear distortion in multi-user hybrid precoding based broadband mmWave systems is an open research problem. In this article, we carry out detailed signal and distortion modeling in broadband multi-user hybrid MIMO systems, with a bank of nonlinear PAs in each subarray, while also take the inevitable crosstalk between the antenna/PA branches into acc
