Abstract—This paper represents the results of a simulation study on positioning of a mobile unit in MIMO settings. We used two different approaches for modeling the mobile movement, combined with a simple geometrical model for the MIMO channel. Three different particle filters were implemented for the position estimation. The results show that all three filters are able to achieve estimation accur
pportunity and recognition isolation can lead directly to reproductive isolation, the former via divergence in the location and timing of breeding, and the latter via differential mate preferences. We describe the potential significance of these factors in the maintenance of reproductive isolation in a clade of triplefin fishes that occur sympatrically around coastal New Zealand. Specifically, we
Net ecosystem–atmosphere exchange of CO2 (NEE) was measured in two boreal bogs during the snow-free periods of 1998, 1999 and 2000. The two sites were located in European Russia (Fyodorovskoye), and in central Siberia (Zotino). Climate at both sites was generally continental but with more extreme summer–winter gradients in temperature at the more eastern site Zotino. The snow-free period in Fyodor
In the 18th and 19th century the The Swedish Hymnbook was, besides the Almanac, one of the most well spread books in Sweden. Among the peasantry it was common to give decorated Hymnbook bindings as a gift at the moment of the engagement. This tradition made the bookbinders produce richly decorated retail bindings of parchment or leather suitable for the occasion. The decoration of these often simp
Organochlorines are widespread pollutants in humans. Concern about adverse reproductive effects of these compounds arises from accidental exposure of humans and experimental studies. Recently, this issue has been addressed by a number of studies of exposed populations and hospital-based case-referent studies. These studies indicate that high concentrations of persistent organochlorines may adverse
A method for fitting regression models to data that exhibit spatial correlation and heteroskedasticity is proposed. It is well known that ignoring a nonconstant variance does not bias least-squares estimates of regression parameters; thus, data analysts are easily lead to the false belief that moderate heteroskedasticity can generally be ignored. Unfortunately, ignoring nonconstant variance when f
This thesis is about the theology of the leader of Anglican evangelicalism, John Stott. Throughout this study of evangelical identity, the relationship between the objective belief and the subjective experience is a main thread. An attempt at definition of the Anglican evangelicalism: Theologically, evangelicalism means that the bibliology and the doctrine of salvation have been in the foreground
In this paper, we propose a new barrier function for optimization problems with Integral Quadratic Constraints (IQCs). The new barrier function is used to construct an interior point algorithm which solves IQC optimization problems in a more efficient fashion. Numerical tests as well as worst-case computational complexity analysis are performed to evaluate the efficiency of the proposed algorithm.

So-called child neuropsychiatric disorders (ADHD/DAMP, autism spectrum disorders, Tourette's syndrome) are being recognized with increasing frequency in child and adolescent psychiatry. Through follow-up studies, case reports and autobiographical accounts it has become evident that these disorders often persist into adulthood, and the need for diagnostic evaluation of adults is increasing. The Neu
Infrared absorption of as-grown, heat-treated and electron irradiated Ge crystals enriched with either O-16 or O-18 oxygen isotopes has been studied. Vibrational absorption bands at 780, 818 and 857 cm(-1) (741, 776 and 811 cm(-1)) are assigned to di-oxygen complexes (dimers) in Ge: O-16 (O-18). This assignment is based on an analysis of positions and isotopic shifts of the lines as well as on an
An object-oriented extension to canonical attribute grammars is described, permitting attributes to be references to arbitrary nodes in the syntax tree, and attributes to be accessed via the reference attributes. Important practical problems such as name and type analysis for object-oriented languages can be expressed in a concise and modular manner in these grammars, and an optimal evaluation alg
