in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...

Dept.of Mechnical Design Eng., Chosun Univ., 375 Seosuk-dong, Dong-gu, Gwangju, Korea, [email protected] In this study, shearography and infrared thermography were used for measuring the wall thinning defects of the nuclear power plants pipes. It is very important to measure the wall thinning defects inside the pipes, because the wall thinning defects cause damage or destruction of the pipes. T...

BACKGROUND The initial trial in tricuspid surgery is repair; however, replacement is done whenever the valve is badly diseased. Tricuspid valve replacement comprises 1.7% of all tricuspid valve surgeries. MATERIALS AND METHODS The present retrospective study was performed using the medical records of 21 cases who underwent tricuspid valve replacement from January 2002 until the end of Decembe...

For broad nanoscale applications, it is crucial to implement more functional properties, especially those ferroic orders, into two-dimensional materials. Here GdI$_3$ theoretically identified as a honeycomb antiferromagnet with large $4f$ magnetic moment. The intercalation of metal atoms can dope electrons Gd's $5d$-orbitals, which alters its state and lead Peierls transition. Due the strong el...
