Fusion of 6 Dimensional Sensor Data using Physics Engines Capture of high speed athletic motion has until now only been possible by using expensive high speed camera systems. This work presents a novel alternative in form of a wireless inertial measurement system. The sensor data from this system is combined using a physics engine andallows a higher resolution calculation of forces and torques ...

Fish passing through dams may be injured or killed despite advances in turbinedesign, project operations and other fish bypass systems. The six-degree-of-freedom (6DOF)Sensor Fish device is an autonomous sensor package that characterizes the physical conditionsand physical stresses to which fish are exposed when they pass through complex hydraulicenvironments. It has been used to identify the l...

a 15-landmark morphometric truss network system was used to investigate the hypothesis of population fragmentation of shad fish alosa braschnicowi borodin, 1904 along the southern caspian sea. a total of 181 a. braschnicowi specimens were caught from six localities, respectively from the west to the east including; astara, rezvanshahr, anzali, tonekabon, sari and miankale. principal component a...

One concern in using photonic band-gap fiber (PBGF) as a gas sensor is the response time. In this type of the gas sensors, response time is the time required for gas to diffuse into the hollow-core. So considering a large hollow-core PBGF (HC-PBGF), the response time can be significantly reduced. But in the large HC-PBGF, the fundamental issue is the presence of higher order modes (HOMs). Somet...

The E-type membrane which is used for measuring forces in other five directions will generate coupling outputs and influence accuracy of the sensor, when six-axis force sensor based on double layer E-type membrane is under dynamic loads in MZ direction. In terms of the fundamental theory of mechanical vibration, vibration mechanics and elastic mechanics, this paper simplifies the E-type membran...

Flight test results and lessons learned are presented for a helicopter UAV low-altitude navigation and landing system. Results are given for both urban and natural settings. The navigation component uses a quasi-3D A* approach to route planning that enables maneuver through complex terrain using real-time sensor data. The landing component performs landings to sites that it determines to be saf...

Principal Component Analysis based anomaly detection approaches have been extensively studied recently. However, none of these approaches address the problem of anomaly localization. In this paper, we proposed a novel approach based on PCA to perform anomaly detection and localization in sensor network simultaneously. By enforcing the joint sparsity across the Principal Component in the abnorma...
