High-performance anion-exchange (HPAE) chromatography under alkaline conditions (pH congruent to 13) has been found to efficiently separate neutral oligosaccharides (triose to undecaose) according to molecular size, sugar composition, and linkage of monosaccharide units. The method was able to resolve 1----3, 1----4, and 1----6 positional isomers of neutral oligosaccharides, which are defined a...

This paper reports previously obtained results concerning topographic change in a water area. Latitude-longitude components of positional data from GPS receiver were transformed to planar orthogonal coordinates, and vertical combined with depth an echo sounder. A piecewise linear function defined on triangular mesh represented surface that fitted measurement results. study applied those techniq...

Aim of this study was to examine possible relationships between several clinical aspects of paroxysmal positional vertigo and factors better defined as "intrinsic" to the patient, above all age. The disorder can affect essentially all age groups; nevertheless, the onset of age-linked degenerative processes, such as vascular damage, can have a negative influence--at least in theory--on the patho...

We study parallel algorithms for addition of numbers having finite representation in a positional numeration system defined by a base β in C and a finite digit set A of contiguous integers containing 0. For a fixed base β, we focus on the question of the size of the alphabet that permits addition in constant time, independently of the length of representation of the summands. We produce lower b...

It is well-known that no voting system can be entirely fair: this is Arrow’s Theorem, which states that under a certain natural definition of fairness, the only fair voting system is a dictatorship. Thus, in democratic political systems, one expects voting paradoxes in which different voting systems give different results. We analyze the mathematical basis of paradoxes amongst a certain class o...

Assumption: The body shape relative to the body frame is a given function of time B0(t). We call this the standard shape. The current body shape B(t) is obtained under a translation and rotation of the body frame. The latter is defined by a positional matrix. To say that locomotion has occurred at time t means we have realized at time t a nonzero translation. Example: steady locomotion in two d...

A‎s we know, developing mathematical models and numerical procedures that would appropriately treat and solve systems of linear equations where some of the system's parameters are proposed as fuzzy numbers is very important in fuzzy set theory. For this reason, many researchers have used various numerical methods to solve fuzzy linear systems. In this paper, we define the concepts of midpoint a...

Introduction Benign Paroxysmal Positional Vertigo is the most common cause of dizziness in elderly people. Recent studies have shown that the elderly present higher Benign Paroxysmal Positional Vertigo recurrence and that vertiginous symptomatology remission varies according to comorbidities and the therapeutic techniques applied. Objective To assess the short-term effectiveness of Vestibular R...

Reactive systems are often modelled as two person antagonistic games where one player represents the system while his adversary represents the environment. Undoubtedly, the most popular games in this context are parity games and their cousins (Rabin, Streett and Muller games). Recently however also games with other types of payments, like discounted or mean-payoff [5,6], previously used only in...
