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 families of solutions for meta-fibonacci recursions related to hofstadter-conway $10000 sequence
(Springer, 2020)Hofstadter-Conway $10000 sequence is a famous meta-Fibonacci sequence which is defined by recurrence relation c(n) = c(c(n-1)) + c(n-c(n-1)) with c(1)=c(2)=1. Based on its amazing fractal-like structure, in this study, we ... -
On flow fluctuation's impact on the performance of vertical axis turbines-A potential flow analysis

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
(Inderscience, 2023)The marine transportation industry, which has made significant steps in recent years to combat climate change and global warming, is heavily influenced by regional and worldwide economic trends. The COVID-19 pandemic, which ... -
Optical and wettability properties of polymers with varying surface energies
(Elsevier Science Bv, 2015)In this study, flat and transparent thin films of polymers with varying surface free energies were prepared from their solutions to investigate their wettabilities and optical properties. Surface free energies of polymers ... -
Optical energy band gap of PAAm-GO composites
(Elsevier Sci Ltd, 2018)Graphene oxide (GO) can be used as an electron acceptor for polymers. The generation of the exciton in such materials is intimately related to the optical band gap. Polyacrylamide (PAAm) - graphene oxide (GO) composites ... -
