The Importance of the Golden Number for Mathematics and Computer Science: Exploration of the Bergman’s System and the Stakhov's Ternary Mirror-symmetrical System (Numeral Systems with Irrational Bases)

Alexey Stakhov · Journal of Advances in Mathematics and Computer Science · 2016

The main goal of the article is to explore two unusual numeral systems, which alter radically our ideas on the positional numeral systems. We are talking on the numeral systems with irrational bases. The first of them is the binary (0,1) numeral system with the irrational base   ...

Some Applications of One and Two- Dimensional Fourier Series and Transforms

Shpetim Rexhepi & Fatmir Hoxha · Journal of Advances in Mathematics and Computer Science · 2016

The paper provides a solid foundation in the fundamentals of one and two-dimensional Fourier series and transforms, examines the representation of periodic non-sinusoidal signals which can include current, voltage, voice, image etc, as sum of infinite trigonometrically series in...

Development of an Improved Cognitive Complexity Metrics for Object- Oriented Codes

O. Isola Esther, O. Olabiyisi Stephen, O. Omidiora Elijah, A. Ganiyu Rafiu, T. Ogunbiyi Dimple & Y. Adebayo Olajide · Journal of Advances in Mathematics and Computer Science · 2016

Cognitive informatics helps in comprehending the software characteristics and its complexity measures can be used to predict critical information about testability of software system. In this paper, a cognitive complexity metric for C++ programming language is formulated. Since C...

Survey of Methods in Sentiment and Emotional Analysis

K. Kesav Raj, G. Sujitha, R. Karthikaeyan & C. Kishore Kumar · Journal of Advances in Mathematics and Computer Science · 2016

People tend to convey emotions and show the sentiment either consciously or unconsciously while they speak or write. Many are under the common delusion that both sentiment and emotion are indistinguishable. Sentiment is the mental attitude originating from the feelings whereas em...

Common Fixed Points of Kannan and Chatterjea Types of Mappings in a Complete Metric Space

Risto Malčeski, Aleksa Malčeski, Katerina Anevska & Samoil Malčeski · Journal of Advances in Mathematics and Computer Science · 2016

This paper contains several generalizations of the theorems for common fixed point of R. Kannan, S. K. Chatterjea and P. V. Koparde & B. B. Waghmode types of mappings. These generalizations are done by using a sequentially convergent mappings. Trough several examples, we have...

Dynamics of Water Hyacinth in a Fishery System with Delay Effect

B. S. N. Murthy & M. A. S. Srinivas · Journal of Advances in Mathematics and Computer Science · 2016

This paper analyses the dynamics of a fishery system in an aquatic environment that consists of two zones: water hyacinth zone and free zone. Fish harvesting is allowed in both the zones and fish migration is allowed from water hyacinth zone to free zone and not back. This paper...

On the Non-Existence of Difference Sets with Perfect Square Order

Adegoke S. Osifodunrin · Journal of Advances in Mathematics and Computer Science · 2016

The existence of Paley-Hadamard (4t − 1, 2t − 1, t − 1) difference sets provides a platform for solving the equation δ¯δ = n in the cyclotomic ring Z[ζ4t−1], where ζ4t−1 is root of unity, n > 1 and t > 1 are integers. We look at cases where ⟨n⟩ = ⟨δ⟩⟨¯δ⟩ in Z[ζ4t−1] but δ¯δ...

Symbolic Dynamics Generated by a Hybrid Chaotic Systems

Carlos Correia Ramos, Ana Isabel Santos & Sandra Vinagre · Journal of Advances in Mathematics and Computer Science · 2016

We consider piecewise defined differential dynamical systems which can be analysed through symbolic dynamics and transition matrices. We have a continuous regime, where the time flow is characterized by an ordinary differential equation (ODE) which has explicit solutions, and the...
