The essence of marine and coastal space – an interdisciplinary perspective
PublicationSea space has been undergoing a profound transformation. Although it retains its inspirational function in arts, literature and philosophy, it has been gaining new anthropogenic dimensions in eco-nomics and urban planning as a source of satisfying human needs i.e. the provision of harmony, beauty, off-shore energy, and biotech substances. Therefore, in this paper marine space is analyzed from a mul-tidimensional perspective of...

Próba uzgodnienia aspektu racjonalnego i aspektu irracjonalnego w myśli antropologicznej Maxa Schelera
PublicationW eseju przedstawiłem próbę uzgodnienia aspektu racjonalnego i aspektu irracjonalnego w Schelerowskiej myśli antropologicznej. Podkreśliłem to, że niemiecki filozof poszukiwał jedności bytu ludzkiego, osoby ludzkiej, jak tez jedności cogitare i ducha w niej samej. Zwróciłem uwagę na to, że "początek" myśli pierwotwórcy dwudziestowiecznej antropologii filozoficznej wiązał się z dynamiczną zmianą "obrazu" "człowiek" - "świat" - "Bóg",...

Voltage and Current Unbalance Reduction in Power Networks with Distributed Generation and Electric Vehicles
PublicationThe current development of prosumer microsources and the expected spread of electric vehicles may cause the appearance of significant current and voltage unbalance in low-voltage (LV) networks. This unbalance, which is an unfavorable phenomenon, may occur when using single-phase photovoltaic (PV) microsources and single-phase home chargers for electric vehicles. This paper presents a proposal for the symmetrization of the LV network...

Estetyka domu jak element warunkujący poczucie przynależności w procesie zamieszkiwania
PublicationDom jest formą schronienia, która stanowi przedmiot w złożonym procesie zamieszkiwania. Jednym z aspektów decydujących o doświadczaniu poczucia utożsamiania w tym procesie jest estetyka tego domu. Dbałość o jej spójność z oczekiwaniami przyszłych mieszkańców i wpasowanie w zastane otoczenie wydają się oczywistym zadaniem architekta. Jednak w przypadku istniejących osiedli mieszkaniowych wielorodzinnych, zwanych potocznie blokowiskami,...
