We present an improved technique for the deprojection and PSF-deconvolution of X-ray surface brightness profiles of galaxy clusters. Our method is tested using simulated profiles, XMM-Newton and Chandra data, and is shown to result in unbiased gas density profiles that retain full information about the gas distribution. We then apply the method to surface brightness profiles of an unbiased samp...

BACKGROUND Nasal valve collapse and especially internal nasal valve insufficiency is a common cause of nasal airway obstruction. This study compares the effects of spreader graft and overlapping lateral crural technique on rhinoplasty by rhinomanometry. METHODS Fifty patients were randomly assigned into two groups and underwent spreader graft or overlapping lateral crural technique. Objectiv...

In this paper, we describe the design of a profile generator toolkit, which aims to automatically create realistic user profiles for a mobile personalized portal service. These profiles simulate actual user behavior and are utilized to experiment with a personalized crawling system, called eRACE. With the help of this tool, we will assess the performance and scalability of the eRACE system by c...

Here we have proposed two algorithms. The first one detects the skewing of words and the second corrects the skewing from handwritten words. Both algorithms make use of the Radon transform based projection profile technique. The method does not require pre-processing and it works equally good even with noise. The method is fast. The algorithms have been tested on words taken from more than 200 ...

Radar target identification using high resolution range profile (HRRP), the target length is an important feature due to that it can reduce the time of identification and mitigate noise redundancy. Traditional threshold methods with the different operators are highly sensitive to noise. In this paper, we proposed an adaptive difference operator for target length feature extraction from HRRP. Ex...
