Abstract : The focus of this paper is to model the spread of COVID-19 within a multi-patch environment. The proposed model incorporates the short- term mobility and it is incorporated with the mobility matrix. A SQIHR model including close contact tracing incorporated with human mobility within patches is discussed. Different scenarios of the imposed mobility restrictions are illustrated with the numerical simulations for the early stage of disease spread in Sri Lanka. The spread of the disease from a hot ... >>More

Abstract : The competing risk is a special branch of medical research where several multiple events can happen. It can encompass the joint modelling approach for dengue epidemiology to model the relation of different destinations of the length of stay and platelet count. Also, the district effect is an inherent feature of dengue highly associated with climate change. Therefore, this leads to the joint multilevel approaches for analyzing the different destinations of the length of stay of a dengue patient a ... >>More

Abstract : Epidemiological models have been of immense use in modelling the spread of infectious diseases and these models have been used to understand the dynamics of infectious diseases and to make predictions on how the disease will behave into the future. In this study, we develop an age-structured extended versions of the classical compartmental model to better under- stand the age specific spread of COVID-19 disease in San Francisco city. We fit actual data into the model to find age specific paramet ... >>More

Abstract : Corona Virus-2019 (COVID-19) is an infectious disease that is spreading in most countries all over the world. Control strategies such as social distancing, quarantine protocols, and hospitalized isolations are used to suppress the spread of COVID-19 in the community. This research proposes a deterministic compartmental mathematical model for the COVID-19 control process by considering the above-mentioned control strategies. Population subclasses; susceptible (S), exposed (E), immigrant (E1), inf ... >>More

Abstract : COVID-19 is one of the worst epidemics in human history. In 2019 infected individuals were found in Wuhan, China, and subsequently, the disease was spread to the other regions in the world too. It is important to identify high risk regions in the world in the context of COVID-19 spread. The dynamics of COVID-19 transmission are complex and uncertain due to various factors such as social, biological, environmental, educational, climate and economic conditions. Fuzzy logic and fuzzy set theory are ... >>More

Abstract : Positioning or location estimation systems are adopted widely in modern world, to locate objects or users. Current broadly adopted positioning sys- tems such as global positioning system (GPS) or global navigation satellite system (GNSS) are limited to outdoor applications and provide poor locating accuracy for indoor positing with short movement span. Through this study we aim to evaluate the possibility of utilizing received signal strength indicator (RSSI) value of a smartphone antenna with t ... >>More
