In this paper we present an application of the Itô stochastic calculus to the problem of modelling RLC electrical circuits. The deterministic model of the circuit is replaced by a stochastic model by adding a noise term to various parameters of the circui... see more

In this research, we propose a method of improving on the accuracy of detecting nasal cavity location in far infrared images for non-contact measurement of human breathing. We found that although our previous method for far infrared imaging can detect reg... see more

The scenario of smart home services will be discussed with regard to two important aspects: the quality of service problem for the in-house communication and the need for a security scheme for the whole system. We focus on an installat... see more
