In this study, inspired by the work of Nakazato and Kitahara (1980 Prog. Theor. Phys. 64 2261), we consider the theoretical problem of tracer particle diffusion in an environment of diffusing hardcore interacting crowder particles. The tracer particle has a different diffusion constant from the crowder particles. Based on a transformation of the generating function, we provide an exact formal expa
The dynamic testing method has been shown to accurately characterize the electromagnetic model of permanent magnet synchronous machines by describing the relationship between the phase currents and the linked magnetic flux with minimal amount of test equipment compared to traditional methods. Within this work, a performance evaluation of the dynamic testing method applied to the synchronous reluct
The aim of this article is to develop the concept of time-space complexity as a way of discussing how territorial time-space production affects urban life and use. The discussion is based on a comparative study of opening hours in four centrally located European retail areas: Angers, Lisbon, Malmö and Porto. Following a comparative study of these areas, we discuss tendencies of temporal and spatia
The statistical resources at hand for segregation research are usually almost exclusively confined to annual or decennial records where the only available spatial information is the individual’s place of residence. This coarse temporal periodicity and spatial resolution provides a very limited account of people’s diurnal lives. Incorporating mobility and temporal dimensions in segregation analysis
This thesis is, to its nature, somewhat wide in scope. The common denominator for theincluded essays is regional economics. Within this very wide area of research, the thesis isdivided rather sharply between one part regarding trading of emission permits in theinternational aviation sector and another part concerned with real estate markets. The basis ofthis thesis is five essays all written for t
