We present two stochastic filters for an FM-band passive air surveillance radar. The first system uses an extended Kalman filter and delay-Doppler measurements to track targets. The second system uses a particle filter to simultaneously track and classify targets. Automatic target recognition is made possible by the inclusion of radar cross section (RCS) in the measurement vector. The extended ...

The applicability of the mono-static radar cross section (RCS) for the weather radar (WR) and the wind turbines (WT) is evaluated by theoretical and numerical results. It is concluded that the RCS scheme is not applicable for objects on the ground and is not a useful parameter for the definition of safeguarding distances of WT to the WR. Proposals for a deterministic case by case numerical trea...

The Real-Time Control System (RCS) Reference Model Architecture provides a well-de ned strategy for development of software components for applications in robotics, automated manufacturing, and autonomous vehicles. ADLs are formally de ned languages for speci cation of software system's designs. In this report, we describe the results of an investigation into the use of an ADL to specify RCS so...

The scattering characteristics of a phased array depends on its feed network. The variation of scattered fields within the feed network affects the antenna mode scattering. In this paper, an attempt is made to determine the radar cross section (RCS) of a planar array with parallel-feed network. The scattered field of the array is obtained by following the path of the signals through the antenna...

We present a simple and convenient method for creating fluid supported bilayers which contain oriented and functional photosynthetic reaction centers (RCs). The supported bilayers are prepared by fusion of proteoliposomes with a glass surface. The proteoliposomes are prepared by spontaneous insertion of RCs into preformed small, unilamellar vesicles. The RCs in these vesicles are shown to be or...

OBJECTIVES To evaluate the short-term and long-term prognostic impacts of acute phase coronary collaterals to occluded infarct-related arteries (IRA) after ST-elevation myocardial infarction (STEMI) in the percutaneous coronary intervention (PCI) era. DESIGN A prospective observational study. SETTING Osaka Acute Coronary Insufficiency Study (OACIS) in Japan. PARTICIPANTS 3340 patients wit...

production of new hybrids is important for growing aquaculture and protecting wild stocks of fish species. a hybrid between female asp × male kutum ( leuciscus aspius ♀ × rutilus frisii ♂) was produced and its growth performance was monitored in two rearing systems for 55 days. the fish held in earthen ponds exhibited higher performance compared to those held in concrete tanks. the results also...

The electric vehicle (EV) is considered a premium solution to global warming and various types of pollution. Nonetheless, a key concern is the recharging of EV batteries. Therefore, this study proposes a novel approach that considers the costs of transportation loss, buildup, and substation energy loss and that incorporates harmonic power loss into optimal rapid charging station (RCS) planning....

this paper provides a comparison of the maximum inter-story drifts and tip acceleration of both a 16 and 30 stories building each with different structural systems; hybrid r.c moment frame with shear walls and hybrid steel frame with shear walls and x bracing which are equipped by passive dampers. each of the building models were analyzed as fully non-linear structures for variety of dampers pl...

The radar cross sections (RCS) of both small and large ships for High Frequency Surface Wave Radar (HFSWR) were studied by using Numerical Electromagnetics Code [4] and by using measurements from a HFSWR system at Cape Race, Newfoundland, Canada. The results of the study indicate that Teleost, a 2405-ton Canadian Coast Guard ship, and large cargocontainer vessels (~36000 ton) have comparable RC...
