In this paper, after defining pure proportional navigation guidance in the 3-dimensional state from a new point of view, range estimation for passive homing missiles isexplained. Modeling has been performed by using line of sight coordinates with a particulardefinition. To obtain convergent estimates of those state variables involved particularly inrange channel and unavailable from IR trackers...

This paper presents payload inspection for identification of spam files using bloom filter in dual core processor. Spam files flood the Internet in an attempt to dump the messages on recipients who do not intend to receive it. Spam costs the sender very little to send and most of the costs are levied to the recipients or the carriers. The proposed system identifies and filters the incoming spam...

A new miniaturized dual-mode microstrip bandpass filter is presented. The filter structure has been fractally generated based on the 4th iteration Minkowski-like pre-fractal geometry, using the conventional dual-mode square ring resonator as the initiator in the fractal generation process. It has been found that the presented filter possesses a size reduction of about 88% as compared with the d...

This study proposes a concurrent dual-band filter that consists of two single-band filters using quarter-wavelength resonators. The two single-band filters, having different feeding structures, can be designed separately. The lower-band filter has tapped feeding structure and the higher-band filter has coupling feeding structure where the input/output line and the lower-band resonator constitut...

A general theoretical description of dual-beam photothermallensing spectroscopy is given. The results are valid for most general conditions, that is, for flowing as well as stationary media, for optically thick as well as optically thin media, and also for any transverse modes of incident pump beams

This paper presents a dual-band bandpass filter by introducing transmission zeroes in the passband of a broadband bandpass filter using square-loop dualmode resonators. The transmission zeroes are achieved by using a dual-mode resonator. The dual-mode resonator is attached to two transmission lines of the same length. These lines are coupled to similar transmission line that are attached to the...

We propose dual-domain filtering, an image processing paradigm that couples spatial domain with frequency domain filtering. Our dual-domain defined filter removes artifacts like residual noise of other image denoising methods and compression artifacts. Moreover, iterating the filter achieves state-of-the-art image denoising results, but with a much simpler algorithm than competing approaches. T...

The flagellated protozoan Giardia lamblia is a recognized public health problem. Intestinal infection can result in acute or chronic diarrhea with associated symptoms in humans. As part of a study to evaluate removal of G. lamblia cysts from drinking water by the processes of coagulation and dual-media filtration, we developed a methodology by using 5.0-microns-porosity membrane filters to eval...
