On a Generalization of Hofstadter's Q-Sequence: A Family of Chaotic Generational Structures
(Wiley-Hindawi, 2018)Hofstadter Q-recurrence is defined by the nested recurrence Q(n) = Q(n - Q(n - 1)) + Q(n - Q(n - 2)), and there are still many unanswered questions about certain solutions of it. In this paper, a generalization of Hofstadter's ... -
On a recursively defined sequence involving the prime counting function
(University of Waterloo, 2021)We prove some properties of sequence A335294 from the On-Line Encyclopedia of Integer Sequences, defined by an = ?(n) - ?(?n-1 k=1ak), where ?(x) is the number of primes ? x. In particular we show that the sequence (an) ... -
On flow fluctuation's impact on the performance of vertical axis turbines-A potential flow analysis
(Amer Inst Physics, 2017)During the last decade, with rapidly increasing deployment of tidal current turbine prototypes in many countries, a number of failures have been reported. Several of these failures were attributed to the intensive flow ... -
On Hofstadter Heart Sequences
(Wiley-Hindawi, 2017)The Hofstadter Q-sequence and the Hofstadter-Conway $10000 sequence are perhaps the two best known examples of meta-Fibonacci sequences. In this paper, we explore an unexpected connection between them. When the Q-sequence ... -
On some classes of 3-dimensional generalized (kappa, mu)-contact metric manifolds

ON TRANSCENDENTAL CONTINUED FRACTIONS in FIELDS of FORMAL POWER SERIES over FINITE FIELDS
(Cambridge University Press, 2021)In the field of formal power series over a finite field, we prove a result which enables us to construct explicit examples of [removed] -numbers by using continued fraction expansions of algebraic formal power series of ... -
On Z-Symmetric Manifold Admitting Projective Curvature Tensor
(DergiPark, 2022)The object of the present paper is to study the Z-symmetric manifold with the projective curvature tensor. At first, we study the case of Z-tensor and projective Ricci tensor being of Codazzi type. Next, we consider recurrent ... -
An on-board energy and environmental analysis within the COVID-19 effects
