This paper presents a novel attitude synchronization framework for tracking control of multiple identical/heterogeneous satellites in formation flying with connected communication graph. The main contribution of the paper is considering sensors' measurement error to derive control gains. Moreover, the proposed strategy need no angular velocity communication. Nevertheless, the tracking synchroni...

Objectives: In this article, a new procedure for increasing the light penetration depth in a tissue is studied and simulated. It has been reported that the most important problem in biomedical optical imaging relates to the light penetration depth, and so this makes a dramatic restriction on its applications. In the optical imaging method, the detection of the backscattered pho...

background: to date, several imaging techniques to track stem cells are used such as positron emission tomography (pet), single photon emission computed tomography (spect), bioluminescence imaging (bli), fluorescence imaging, ct scan and magnetic resonance imaging (mri). although, overall sensitivity of mri compared to spect and bioluminescence techniques are lower, but due to high spatial reso...

Background and purpose: Dual-energy mammography technique is used for improving the accuracy of breast cancer diagnosis especially in dense breast cases and also detection of micro-calcifications which are early signs of breast cancer. The purpose of this study was to investigate the automatic separation feasibility of micro-calcification images in breast tissue images and evaluating its accura...
