A note on the Ramsey number for small graphs
( Taylor and Francis Ltd. , 2022 , Article)Problems in the Ramsey theory form a well-known family of mathematical problems. We present the exact value of the Ramsey number R(θ6, W5), where θ6 is the set of theta graphs of order 6 and W5 is the wheel graph of order ... -
Applications of evacuated tubes collector to harness the solar energy: a review
( Taylor and Francis Ltd. , 2022 , Article Review)Solar energy is a need of an hour. At present, due to the global warming effect, researchers are moving towards the research work on solar energy. Solar energy can be harnessed by solar thermal collectors. Flat plate ... -
Edge-maximal -free non-bipartite Hamiltonian graphs of odd order
( Taylor and Francis Ltd. , 2022 , Article)Let (Formula presented.) denote the class of non-bipartite graphs on n vertices containing no (Formula presented.) -graph and (Formula presented.) Let (Formula presented.) denote the class of non-bipartite Hamiltonian ... -
Edge-Maximal Graphs Without θ2k+1-Graphs
( Taylor and Francis Ltd. , 2014 , Article)Let σ(n; θ2k+1) denote the class of non-bipartite graphs on n vertices having no θ2k+1- graph and f(n; θ2k+1) = max{ ε(G): G ∊ σ (n; θ2k+1)}. In this paper we determine f(n; θ2k+1), by proving that for k ≥ 4 and n ≥ 36k. ... -
Effect of two types of graphene nanoplatelets on the physico-mechanical properties of linear low-density polyethylene composites
( Taylor and Francis Ltd. , 2016 , Article)The influence of two types of graphene nanoplatelets (GNPs) on the physico-mechanical properties of linear low-density polyethylene (LLDPE) was investigated. The addition of these two types of GNPs - designated as grades ...
