Neurofibromatosis type 1 (NF-1) is an autosomal dominant disorder. Pseudoaneurysms formation and rupture is an unusual complication of neurofibromatosis. To date, pseudoaneurysm of the internal pudendal artery associated with NF-1 has not been reported. In this article, we present a 62-yr-old man with NF-1 suffering from spontaneous hematoma of the perinea and scrotum. A digital substraction an...

In this paper we present a robust noise estimation for speech enhancement algorithms. The robust noise estimation based on a modified minima controlled recursive averaging noise estimator was applied to different speech estimators. The investigated speech estimators were spectral substraction (SS), log spectral amplitude speech estimator (LSA) and optimally modified log spectral amplitude estim...

This paper presents a new mono-camera system for traffic surveillance. It uses an original algorithm to obtain automatically a calibration pattern from road lane markings. Movement detection is done with a Σ−∆ background estimation which is a non linear method of background substraction based on comparison and elementary increment/decrement. Foreground and calibration data obtained allow to det...

A63-year-old woman was referred for evaluation of a transient ischemic attack with right arm and leg involvement. On examination, she had a right neck bruit. The head CT scan showed a small, old ischemic infarction in the periventricular area of the right frontal lobe. Digital substraction angiography revealed a total occlusion of both internal carotid arteries, a severe stenosis of the origin ...

In this paper we propose some very promissing results in interval arithmetics which permit to build well-defined arithmetics including distributivity of multiplication and division according addition and substraction. Thus, it allows to build all algebraic operations and functions on intervals. This will avoid completely the wrapping effects and data dependance. Some simple applications for mat...

The Superior Thyroid Artery (STA) is the dominant arterial supply of the thyroid gland, larynx and the neck. Awareness of variations in STA is crucial for invasive operations in the neck region. We reported a case that STA derives from the Common Carotid Artery (CCA). A patient with possible transient ischemic attack had an digital substraction angiography. Angiography revealed superior thyroid...

A 22-year-old female patient presented to the Emergency Department of a tertiary care hospital with symptoms of headache and nausea. She has been on a regular follow-up for the preceding three and a half years after being diagnosed as systemic lupus erythematosus (SLE). She had been treated earlier for SLE nephritis in the same institution, and had two relapses of nephrotic syndrome in the last...
