Computerized Ionospheric Tomography With The Iri Model
(Elsevier Sci Ltd, 2007)
Computerized ionospheric tomography (CIT) is a method to estimate ionospheric electron density distribution by using the global positioning system (GPS) signals recorded by the GPS receivers. Ionospheric electron density ...
Synthetic Tec Mapping with Ordinary and Universal Kriging
(Ieee, 2007)
Spatiotemporal variations in the ionosphere affects the BF and satellite communications and navigation systems. Total Electron Content (TEC) is an important parameter since it can be used to analyze the spatial and temporal ...
On The Noncommutative Neutrix Product Of Distributions
(Hindawi Publishing Corporation, 2007)
Let f and g be distributions and let g(n) = (g * delta(n))(x), where delta(n)(x) is a certain sequence converging to the Dirac-delta function delta( x). The noncommutative neutrix product f circle g of f and g is defined ...
On Powers Of The Heaviside Function For Negative Integers
(Academic Press Inc Elsevier Science, 2007)
The distributions (x(+)(r))(-s) and (x(+)(r))_(-s) were defined as the neutrix limit of the sequences ((x(+)(r))(-s))n and ((x(+)(r))_(-s))n respectively for r, s = 1, 2,..., see [J.D. Nicholos, B. Fisher, The distribution ...

Remarks on Separation of Convex Sets, Fixed-Point Theorem, and Applications in Theory of Linear Operators
(Springer International Publishing Ag, 2007)
Some properties of the linear continuous operator and separation of convex subsets are investigated in this paper and a dual space for a subspace of a reflexive Banach space with a strictly convex norm is constructed. Here ...
Human Milk Fat Substitute Produced By Enzymatic Interesterification Of Vegetable Oil Blend
(Faculty Food Technology Biotechnology, 2007)
Palm oil, palm kernel oil, olive oil, sunflower oil, and marine oil blend, formulated in the mass ratio of 4.0:3.5:1.0:1.5:0.2, was subjected to interesterification catalyzed by lipase from Thermomyces lanuginosa (Lipozyme(R) ...
Spectroscopic And Electrochemical Observation Of Hydrogen-Bonded Imidazole And 2-Aminoimidazole Clusters
(Slovensko Kemijsko Drustvo, 2007)
The electroreductions of imidazole and 2-aminoimidazole were investigated on a Pt electrode in acetonitrile containing tetrabutylammonium tetrafluoroborate with and without the presence of HBF4. The effects of lithium and ...
Regularized Estimation of Tec from Gps Data for Certain Midlatitude Stations and Comparison with the Iri Model
(Elsevier Sci Ltd, 2007)
Regularized estimation of Total Electron Content (Reg-Est) is a novel technique which can combine signals from all the satellites for a given instant and given station and estimate the vertical TEC (VTEC) values for any ...
On Modules And Matrix Rings With Sip-Extending
(Mathematical Soc Rep China, 2007)
In this note we study modules with the property that the intersection of two direct summands is essential in a direct summand (SIP-extending). Amongst other results we show that the class of right SIP-extending modules is ...
