The mathematical model of steady state mono-layer potentiometric biosensor is studied and the model is based on nonstationary diffusion equations containing a non-linear term related to Michaelis-Menten kinetics of the enzymatic reaction. This paper presents a numerical method based on Legendre wavelets operational matrix method. These results are compared with available limiting case results a...

A new computational method based on Haar wavelets is proposed for solving multidimensional stochastic Itô-Volterra integral equations. The block pulse functions and their relations to Haar wavelets are employed to derive a general procedure for forming stochastic operational matrix of Haar wavelets. Then, Haar wavelets basis along with their stochastic operational matrix are used to approximate...

To increase precision and reliability of automatic control systems, we have to take into account of random factors affecting the control system. Thus, operational matrix technique is used for statistical analysis of first order plus time delay system with uniform random parameter. Examples with deterministic and stochastic disturbance are considered to demonstrate the validity of the method. Co...

entrapment of permeabilized whole cells within a matrix is a common method for immobilization. chitosan possesses distinct chemical and biological properties, which make it a suitable matrix for entrapment and immobilization of penicillin g acylase (pga). in the first step, escherichia coli (atcc 11105) cells were permeabilized using n-cetyl-n,n,n-trimethyl ammonium bromide (ctab) (0.1% w/v, 45...

General medical practices’ in Australia are vulnerable to information security threats and insecure practices. It is becoming well accepted in the healthcare environment that information security is both a technical and a human endeavour, and that the human behaviours, particularly around integration with healthcare workflow, are key barriers to good information security practice. This paper de...

The fractional calculus has many applications in applied science and engineering. The solution of the differential equation containing fractional derivative is much involved. An effective and easy-to-use method for solving such equations is needed. However not only the analytical solutions exist for a limited number of cases, but also the numerical methods are very complicated and difficult. In...
