On the Stability Analysis of MDGKN Systems with Control Parameters

Ubong D. Akpan & Moses O. Oyesanya · Journal of Advances in Mathematics and Computer Science · 2017

In this work, we study linear systems with Mass, Damping Force, Gyroscopic Force, Stiffness and Circulatory Force (MDGKN systems) with control parameters. The relationship between the parameters determines the stability or otherwise of the system. The Lyapunov direct method is us...

Modelling the Dynamics of Smoking Epidemic

Mojeeb AL-Rahman EL-Nor Osman & Isaac Kwasi Adu · Journal of Advances in Mathematics and Computer Science · 2017

Our study is made up two sections: Non-smokers, problem- smokers, smokers-in-treatment and counselling, and removed-smokers (SPTcR) mathematical model that explains the dynamics of smoking epidemic without considering the recovery class to susceptible class transferring followed...

Full Observability Criteria for Linear Impulsive Control Systems with Application to Diabetes Type I Dynamics

P. S. Rivadeneira · Journal of Advances in Mathematics and Computer Science · 2017

The main goal of this paper is to derive a full characterization of the observability of linear time-invariant impulsive systems. Two cases are studied. The firrst case considers continuous outputs. A suitable adapted Kalman criterion is shown to characterize properly the observa...

Novel Technique for IRFPA Blind Pixels Detection

Abdulaziz Mohammed Algamdi & Ahmad Abbas Ahmad Adas · Journal of Advances in Mathematics and Computer Science · 2017

Infrared focal plane array (IRFPA) is a bi-dimensional infrared detector which is a matrix of micro detectors referred as pixels. Physical pixel failure (blind pixel) is a serious issue in case of utilizing IRFPA as a measuring tool or a surveillance system to monitors hot object...

Characterization of Time to Failure in Prognostics: Brief Tutorial Guide to Prognostics Professionals

Ali M. Rushdi & Hasan A. Bjaili · Journal of Advances in Mathematics and Computer Science · 2017

As a random variable, the survival time or Time to Failure (TTF) of a certain component or system can be fully characterized by its probability density function (pdf) fT (t) or its Cumulative Distribution Function (CDF) FT (t). Moreover, it might be also identified by transform f...

Geometric Aspects of Denseness Theorems for Dirichlet Functions

Dorin Ghisa & Andrei Horvat-Marc · Journal of Advances in Mathematics and Computer Science · 2017

The first theorem related to the denseness of the image of a vertical line Re s = σ0, σ0 > 1 by the Riemann Zeta function has been proved by Harald Bohr in 1911. We argue that this theorem is not really a denseness theorem. Later Bohr and Courant proved similar theorems for th...

Modelling Influenza Dynamics with Drug Resistance Aspect

Caroline W. Kanyiri, Mark Kimathi & L. S. Luboobi · Journal of Advances in Mathematics and Computer Science · 2017

Despite improvement in medical and public health standards, influenza continues to plague humankind causing high morbidity,mortality and socio-economic cost. Efforts to effectively combat the spread of influenza can be put in place if its dynamics are well understood. Numerous ch...

Some Fixed Point Theorems for Berinde-Type Contraction Mappings on Gp-Metric Spaces

Şeyma Çevik & Hasan Furkan · Journal of Advances in Mathematics and Computer Science · 2017

In this paper, we define the concepts of (δ, 1 − δ)-weak contraction, (φ , 1 − δ)-weak contraction and Ćirić-type almost contraction in the sense of Berinde in Gp-complete Gp-metric space. Furthermore, we prove the existence of fixed points and common fixed points of mappings sat...
