Correlation Between Preparation Methods and Optical Properties of Chitosan from Shrimp for Application in Optoelectronic Devices
(JOOUST, 2022)
Over the recent years, the global increase of electronic wastes from electrical and electronic devices (e-wastes) have been on an alarming trend in quantity and toxicity and e-waste are non-biodegradable resulting into its ...
Tensor Products and Norms of Inner Derivations Induced by Norm-Attainable Operators
(JOOUST, 2018)
Several investigations have been done on properties of derivations act¬ing on C* -algebras and their subalgebras and these include their norms, boundedness, numerical ranges, spectra and the operators inducing them. The ...
Bilateral Shifts and Spectrum of Compact Operations
(JOOUST, 2018)
Shift operators are important operators in functional analysis in the study of other operators like compact operators, finite operators, normal opera-tors among others. Left shifts, right shifts and unilateral shifts have ...
On Norm Preserving conditions for Local Automorphisms of Commutative Banach Algebras
(JOOUST, 2017)
Most studies on preserver problems have been on linear preserver prob¬lems (LPPs) in matrix theory. It is known that local derivations of Von Neumann algebras are continuous linear maps, which coincide with some derivation ...
Mathematical Model for Drug Therapy in Asthmatics
(JOOUST, 2016)
Asthma is a chronic disease that involves inflammation of the airways. Pa¬tients with Asthma have a constriction of the airways in the lungs and con¬sequent difficulty in breathing out. This ailment can be alleviated by ...
Numerical Solution of Dynamic Vibration Equation with Restoring Force x = sech x
(JOOUST, 2018)
Dynamic vibration equations are of great importance not only for un-derstanding the dynamic motion of structures, but also for providing knowledge of differential equations to mathematicians. Although sev¬eral studies have ...
Lie Symmetry Analysis of Third Order NonLinear Ordinary Differential Equation
(JOOUST, 2018)
A few third order nonlinear Ordinary Differential Equations can be solved explicitly and one must typically rely on numerical scheme to approximate the solution. However to overcome this problem Lie symmetry reduction of ...
Norms and Maximal Numerical Range of Jordan Elementary Operators
(JOOUST, 2017)
Elementary operators originated from the study of the Sylvester and Rosenblum equation AX - X B = Z. Although a lot of work on vari¬ous properties of elementary operators has been done, the norm property still remains an ...
Spectral Characterization of Jordan Homophorphisms on Semisimple Banach Algebras
(JOOUST, 2018)
Certain properties of operator algebras have been studied such as bound¬edness, positivity, surjectivity, linearity, invertibility, numerical range, nu¬merical radius and idempotent property. Of great interest is the study ...
