Stability Constants in Linear Spaces

Constructive Approximation, 2010
Let \(X\) be a linear space over the reals, \(D\subset X,\) and let \(E\) be a Banach space. A function \(f:D\to E\) is said to be \(\delta\)-Jensen if \[ \left\| f\left(\frac{x+y}{2}\right)-\frac{f(x)+f(y)}{2}\right\|\leq\delta \] whenever \(x,y,(x+y)/2\in D.\) The stability constant for Jensen equation is the infimum of those constants \(C\) for ...

Stability Constants for Courant Approximations

Journal of Mathematical Sciences, 2001
Summary: This article deals with investigation of constants of stability for the Courant approximation in metrics of spaces \(L_2\) and \(W_2^1\) in the class of triangular grids with uniformly bounded angles as well as with angles which tend to zero. In the first case numerical estimates of the Courant constants are proposed.

The stability constant of complex

The International Journal of Applied Radiation and Isotopes, 1980
Abstract The extraction of technetium in reduced valence state from aqueous perchlorate solutions with thenoyltrifluoroacetone in toluene was studied. Values of the reduced technetium partition coefficient in the presence of various concentrations of diethylenetriaminepentaacetate were measured. The dependences of the reduced technetium (labeled with

On the Convergence of Stability Constants

SIAM Journal on Numerical Analysis, 1986
The paper deals with a linear integro-differential equation of order \(m\in N\) under linear boundary conditions \(Lu:=u^{(m)}+L^{(2)}u=f\) in (a,b), \(B_ eu=c_ e\), \(e=1,...,m\). This problem is approximated by a sequence of finite difference equations.

Piecewise-Constant Stabilization

SIAM Journal on Control and Optimization, 1999
In this paper the author addresses the feedback stabilization problem for continuous-time and discrete-time nonlinear control systems. After presenting necessary conditions for the stabilization via smooth feedbacks, the author turns to the main topic, which is the stabilization via piecewise constant feedback laws, i.e. mappings \(u: \mathbb R^n\to U\)

The stability constant of Pd-EDTA

Talanta, 1978
The literature value of the stability constant of the palladium-ethylenediaminetetra-acetate complex (log K(Pd-EDTA) = 18.5), is open to question. From replacement experiments with thorium a value log K(Pd-EDTA) = 26.4 has been found. This value is in better agreement with experimental facts from protonation studies at low pH and with the fact that ...

The comparison of stability constants

Journal of Chemical Education, 1968
In some texts, the stability of complexes with polydentate ligands is done incorrectly by comparing the numerical value of the stability constant with the numerical value of the overall constant of...

Stability Constants and Their Measurement

1996
The equilibrium constant involving the formation of a metal complex from the aquo metal ion and the most basic form of the ligand is a standard measure of the effectiveness of the ligand in coordinating metal ions. The constants involved are called stability constants or formation constants.

Stability constants of aluminium fluoride complexes

Talanta, 1971
Pointwise titrations of aluminium nitrate solutions with sodium fluoride were made at ionic strengths of 0.5, 0.2, 0.1 and 0.05M and at temperatures of 25 degrees and 37 degrees . The total Al(3+) concentration was kept constant at 5 x 10(-4)M and the total F(-) concentration covered the range 5-20 x 10(-4)M with a minimum of 20 points per titration ...

Stability constant for the zinc-dithiothreitol complex

Analytical Biochemistry, 1972
Rat liver histidase is competitively inhibited by a variety of compounds that are good complexing agents for Zn+2. Dithiothreitol is a strong competitive inhibitor, but 20 μM Zn+2 completely reverses the inhibitory action of 1.7 mM dithiothreitol. Effectiveness of inhibitors is directly related to the stability constants (Kst) for the corresponding ...
