Sustainable Urban Mobility Plans: implementation process and indicators to evaluate effects on physical activity
PublikacjaBackground: Active mobility and public transport increase physical activity (PA) levels. With varying intensity and effectiveness, European cities implement Sustainable Urban Mobility Plans (SUMPs) to spur transport-related PA. Therefore, we aim to examine drivers and barriers to SUMP implementation and assess its influence on PA across European cities. Methods: We screened policy reports to gain insights into SUMP implementation...

Modeling the impact of discretizing rotor angular position on computation of field-oriented current components in high speed electric drives
PublikacjaModern drives consist of alternating current electric motors, and the field-oriented control (FOC) of such motors enables fast, precise, and robust regulation of a drive's mechanical variables such as torque, speed, and position. The control algorithm, implemented in a microprocessor, requires feedback from motor currents, and the quality of this feedback is essential to a drive's control properties. Motor phase currents are sampled...

Narratives on cutting down trees on private land. A comparison of urban and rural municipalities in Poland using the Q-deliberation method
PublikacjaIncreased development in rural and urban areas leads to a decrease in tree cover and reduces the ecosystem services that trees provide. Municipal authorities must consider managing trees on private land to ensure that residents have access to trees and green spaces. In doing so, they must frequently confront conflicting stakeholder views, which are driven by diverse public and private interests and impacted by the type of landscape...

Tradition in a context of hyper-dynamic multicultural urban space
PublikacjaOd początku lat 70. Zjednoczone Emiraty Arabskie były miejscem gwałtownego rozowju gospodarczego, któremu towarzyszył równie dynamiczny wzrost urbanizacji, jak również wzrost populacji. Obecnie ponad 80% współczesnej populacji tego silnie zakorzenionego w tradycjach arabskich kraju to imigranci. Do kryzysu 2008 roku rozwój miast odbywał się praktycznie bez ograniczeń finansowych, jednak z rozmachu pojedyńczych budowli wykreowane...
