In this paper we investigate stability analysis for discrete-time switched systems. We first consider quadratic Lyapunov functions defined over a nonminimal state encompassing the past history of the state trajectory over a finite horizon. This allows us t ...
Extraction of potassium into magmas and outgassing of argon during melting constrain the relative amounts of potassium in the crust with respect to those of argon in the atmosphere. No more than 30% of the modern mass of the continents was subducted back i ...
The history and chem. are described of onium compds., saltlike compds. contg. a complex cation in which the central atom is of an element with nonmetallic character. [on SciFinder (R)] ...
The interdisciplinary character of urban morphology using the fundamental trio - form, scale and history - tries to characterize what we call the primitive morphological ontology. However, this ontology is less useful in other domains unless a formal langu ...
This paper presents a study that aims to review the awareness tools provided by video games to support team-play and team collaboration/communication. It also focuses on the use of these tools in groupware. A content analysis of gamers interview, the games ...
Rational homotopy theory is the study of topological spaces “modulo torsion”. When rational homotopy theorists calculate algebraic invariants of a topological space, such as its homotopy or homology groups, they retain only the nontorsion information. Alge ...
On November the 14th 1974, Jack Cornaz died in Lausanne, the town where he was born in 1886. This study traces the unusual career of this architect – a singular figure in the field of Swiss-French architecture of the twentieth century – whose name, from th ...
Worldwide globalization increases the complexity of problem solving and decision-making, whatever the endeavor is. This calls for a more accurate and complete understanding of underlying data, processes and events. Data representations have to be as accura ...
