Abstract

Virus is a microorganism that can spread and infect living cells, such as humans, animals, and plants. Not all viruses have negative effects, as in the case of oncolytic viruses. This type of virus is modified to infect and kill cancer cells. The success of cancer therapy using this virus depends on the pattern of interaction between the virus population and cancer cells, which can be described by a mathematical model. This research uses two methods to estimate the growth of cancer cells with oncolytic virus therapy, namely the Extended Kalman Filter (EKF) and the Ensemble Kalman Filter (EnKF). The results show that EKF has a faster computation time compared to EnKF. However, the EKF estimation results are still inferior to those of EnKF.

Abstract

All graphs in this paper are simple and connected graph. Let V (G) and E(G) bevertex set and edge set. A map f : .V (G) −→ {0, 2, ..., 2kv} and f : E(G) −→ {1, 2, ..., ke} are sind to be an irregular reflexive labelling where k = max{2kv, ke} for kv, ke are natural number. The weight of edge u, v ∈ E(G) under f is w(u) = f(u)+Σuv∈V (G)f(uv). The function f is called local edge irregular reflexive labeling if every two adjacent edges has distinct weight and weight of a edge is defined as the sum of the labels of edge and the labels of all vertex incident this edgeWhen we assign each edge of G with a color of the edge weight w(uv), thus we say the graph G admits a local edge irregular reflexive coloring. The minimum number of colors produced from local edge irregular reflexive coloring of graph G is reflexive local irregular chromatic number denoted by χlrecs(G). Furthermore, the minimum k required such that χlrecs(G) = χ(G) is called a local reflexive edge color strength, denoted by lrecs(G). In this paper, we learn about the local edge irregular reflexive coloring and obtain lrecs(G) of planar related graphs.

Abstract

Graph colouring is giving colour to a set of vertices and a set of edges on a graph. The condition for colouring a graph is that each colour is different for each neighbouring graph member. Graph colouring can be done by mapping a different colour to each vertex or edge. Rainbow colouring is part of the rainbow-connected edge colouring, where every graph G has a rainbow path. A rainbow path in graph G is formed if two vertices on graph G do not have the same colour. The minimum number of colours in a rainbow-connected graph is called the rainbow connection number denoted by rc(G). The graphs used in this study are the snail graph (Sn), the coconut shoot graph (CRn,m) and the lotus graph (Lon).

Abstract

A set D⊆ V(G) is a dominating set if every vertex of u ∈ V(G) satisfies one of the conditions u is an element of D or u is a neighbor of some point v ∈ D. The minimum cardinality of dominating set in graph G is called domination number which is symbolized by γ(G). Strong dominating set of a graph G is a subset of V(G) where the condition is that the dominating point must have the greatest degree or be equal to the dominating point. The minimum cardinality of strong dominating set is called strong domination number which is symbolized by γ_st(G). In this study, the graphs to be examined are the closed helmet graph (CH_n) with n≥ 3 and the dutch windmill graph (D_{n,5}) with n≥2.
