In this article, we present a particle filter (PF)-based track-before-detect (PF TBD) procedure for detection of extended objects whose shape is modeled by an ellipse. By incorporating of an existence variable and the target shape parameters into the state vector, the proposed algorithm performs joint estimation of the target presence/ absence, trajectory and shape parameters under unknown nuis...

In this research, a new method called elastic surface algorithm is presented for inverse design of 2-D airfoil in a viscous flow regime. In this method as an iterative one, airfoil walls are considered as flexible curved beams. The difference between the target and the current pressure distribution causes the flexible beams to deflect at each shape modification step. In modification shape algor...

در این مطالعه ژنومی متشکل از 10 کروموزوم هر یک به طول 200 سانتی¬مورگان شبیه¬سازی شد. نشانگرها بر روی ژنوم با فواصل 2/0 سانتی¬مورگان طراحی شدند و جایگاه‏های ژنی مؤثر بر صفات بر روی ژنوم با توزیع تصادفی و تعداد متغیر شبیه¬سازی شدند و تنها اثرات افزایشی ژنها در نظر گرفته ¬شد. در ابتدا جمعیت پایه¬ای از حیوانات با اندازه مؤثر 100 (50 نر و 50 ماده) شبیه¬سازی شد و این ساختار جمعیتی برای 50 نسل با آمیز...

Introduction: Curcumin is a water-insoluble agent with some anticancer and antimicrobial effects; while, solubility is essential for a medicine to reach target cells. This study set out to use chitosan tripolyphosphate nanoparticles (CTN) for making curcumin water-soluble, and delivering the required dosage of it to target cells. ...

A review of previous studies shows that there are two general views on how to determine demand in structures through incremental nonlinear static analysis. In the first view, multi-modal methods are used to determine demand in structures. In this view, the applied load pattern is applied to the structure according to the shape of each vibration mode, assuming that the structure deformation foll...

    Different characters influence the marketing of rice in which aroma, amylose content, gelatinization temperature, gel consistency and grain shape are the most important ones. Two local quality (Shastak and Domsia) and two improved rice varieties (Nemat and Fajrr) were used to pyramid the qualitative genes into new released Ghaem variety through classical methods and marker aided selection. ...

With the development of sonar technology, images have been widely used to detect targets. However, there are many challenges for in terms object detection. For example, detectable targets data more sparse than those optical images, real underwater scanning experiment is complicated, and image styles produced by different types equipment due their characteristics inconsistent, which makes it dif...

Spatial context can alter perceived shape, and temporal context can influence the perception of a stimulus. We sought to determine the time course of shape interactions by using a paradigm in which closed shape contours are laterally displaced over space and time. Target and masks are separated by various stimulus onset asynchrony (SOA) values, yielding forward, backward, and simultaneous maski...

This paper presents a method to reconstruct the 3D surface of a tooth given partial information about its shape. A statistical model comprising a mean shape and a series of deformation modes is obtained offline using a set of specimens. During reconstruction, rigid registration is performed to align the mean shape with the target. The mean shape is then deformed to approximate the target by min...
