Join query optimization is a complex task and is central to the performance of query
processing. In fact it belongs to the class of NP-hard problems. Traditional query optimizers …

This paper discusses methodological problems of accurate area determination in the
cadaster. The paper contrasts the ambiguous legal definition of the parcel boundary and …

The Earth's crust is exposed by tectonic processes and is not static over time. Modelling of
the Earth's surface velocities is of utmost importance for research in geodesy, geophysics …

Schenkerian music theory supposes that Western tonal compositions can be viewed as
hierarchies of musical objects. The process of Schenkerian analysis reveals this hierarchy …

Parglare is a Python parsing library that implements deterministic LR and its generalized
extension GLR algorithms. Parglare strives to be easy to use by providing rich error …

The density of a submagma with respect to a free magma is defined as the asymptotic ratio
of their growths. This notion, similar to the inverse of the index for groups, permits …

We survey free magmas and we explore the structure of their submagmas. By equipping the
cyclic free magma with a second distributive operation we obtain a ringoid-like structure with …

The quantum Hall effect has been the prototypical example for many emerging fields of
Physics, including the study of topological phases of matter, topological order, and …

Queueing theory plays a crucial role in modelling systems with congestion. It has been long
applied in analyzing and improving the performance of communication systems. As modern …

We model a set of point-to-point transports on a network as a system of polydisperse
interacting self-avoiding walks (SAWs) over a finite square lattice. The ends of each SAW …
