Objective: To develop a low-cost electromagnet for extraction of metallic intraocular foreign body.Methods: This is an experimental study of an improvised electromagnetic Biscuit Board device for extraction of intraocular metallic foreign body in a porcine eye.The device is an electromagnet made from locally available electronic materials.It is equ
In this paper we propose a new level set approach to describe not only a flame's surface but also to the flame's spatial distribution.First, we derived the mathematical formulation for a one-dimensional laminar premixed flame, Fridge Handle Set where the steady flame has a finite thickness depending on the diffusion flux whose physical qu
A rigorous exploration of the sea ice data assimilation (DA) problem using a framework specifically developed for rapid, interpretable hypothesis testing is presented.In many applications, DA is implemented to constrain a modeled estimate of a state with observations.The sea ice DA application is complicated by the wide range of spatiotemporal scal
In this paper, we evaluate the economic value that arise from incorporating conditional volatility when forecasting the covariance matrix of returns for both short and long horizons in the Vietnamese stock market, using the volatility timing framework of Fleming et al.(2001).We report three main findings.First, investors are willing to pay to switc
