Tracking a maneuvering target with quadcopter is challenging problem, that involves variety of fields such as visual tracking, state estimation, and control algorithms. Most existing unmanned aerial vehicle (UAV) systems fail to track targets accurately in the long term cannot relocate after loss. This paper aims design implement vision-based tracking system for quadcopters can steadily ground ...

Background: Detection of fetal sex is valuable for parents. The aim of this study was detection of fetal sex in suspect cases recessive related to sex disease in first trimester of pregnancy. Material and method: After collecting C.V samples and separating from mother’s samples, their DNAs have been extracted, then doing PCR, finally the sex of them detected. Also, after increase in sensitivit...

This paper presents an Automatic Target Recognition (ATR) system for laser radar (LADAR) imagery, designed to classify objects at multiple levels of discrimination (target detection, classification, and recognition) from single LADAR images. Segmentation is performed in both the range and non-range LADAR channels and results combined to increase object detection rate or decrease false positive ...

intrusion detection in wireless networks has been a challenging researchproblem in network security for more than half a century. this paper presents anovel intrusion detection method based on received signal strength acceptancetest (rssat) to improve the ids capabilities in anomaly-based host-basedintrusion detection systems (hids). the new system can identify suspiciousbehaviors detecting ano...

Cloud computing has become an attractive target for attackers as the mainstream technologies in the cloud, such as the virtualization and multitenancy, permit multiple users to utilize the same physical resource, thereby posing the so-called problem of internal facing security. Moreover, the traditional network-based intrusion detection systems (IDSs) are ineffective to be deployed in the cloud...

In order to solve the question that the photoelectric detection system is vulnerable to environmental factors in complex environment, which affects the detection of target recognition, and then the detection capability of the system is reduced. The double light path detection target recognition method is proposed. This research aims to study the characteristics of output signal that Raindrops a...
