We introduce pseudoquaternions as an effective tool to describe the vector analysis in L3 , and we use them to characterIze null curves and null cubics in S12 .Keywords: pseudoquaternions, vector analysis, null curves

This is the continuation of a previous article titled "Fuzzy Games", where I defined a new type of games based on the Multilinear extensions f, of characteristic functions and most of standard theorems for cooperative games ...

We introduce the notion independent increment in quasi-intervals. Some properties of the fixed points of these processes are studied, as well as those of the aditive descomposition. Finally, we establish the relation between ...

We present a computational implementation in MATHEMATICA of the dual Statis method and we use the method for the growth analysis of some kind of sugar cane.Keywords: multivariate date analysis, MATHEMATICA, multiple tables, ...

A method to solve the isomorphism problem for graphs is suggested, which significantly decreases the number of variants to be checked. Based on the substitution of two successions, the necessary and sufficient conditions ...

From the conservation equation of the quantity of movement and the kinetic energy of the studied turbulence, the dynamics of flat and turbulent path in a non comprehensive liquid environment. In the case of a liquid flow ...

We present the schedule problem that include, in addition to the assignment of timing to teaching activities, the assignment of these activities to classrooms with different capacities, and that are supposed available at ...

ACPPlot is a command for creating graphics for Principal Component Analysis (PCA), principal planes and correlation circles; in both cases, adding options for joining points with trajectories, clustering points, labeling ...
