Abstract:

The static program analysis is gradually adopting advanced use cases, and integration with programming tools becomes more necessary than ever. However, each integration requires a different kind of functionality implemented within an analyzer. For example, continuous integration tools typically analyze projects from scratch, while doing the same for code querying is not efficient performance-wise. The code behind such use cases makes «service models», and it tends to differ significantly between them. In this paper, we analyze the models which might be used by the static analyzer to provide it

Abstract:

The MCSA is a special-purpose digital signal processor. Its main function is to filter a wide-band signal into many narrower bands, so that each of the output bands has a bandwidth that is a better match to the signal being searched for.The basic MCSA provides simultaneous output bandwidths of approximately 1 HZ, 32 Hz, 1024 Hz, and 74 kHz over a spectrum that is about 8 MHz wide. The input to the MCSA consists of a complex signal sampled at 10 MHz, and the outputs consist of either complex samples or power (square-law-detected) samples. In addition, the MCSA provides an accumulator for taking

Metrical poetry in any language is called Chandassu ( ). It generates rhythm to poem when the predefined metric rules are properly followed. The classification of Chandassu is done with the help of syllables known as Laghu ( ), Guru (....) and Gana (..). The proposed metric analyzer for Kannada verse is a rule-based teaching and learning tool devised to identify and classify the Chandassu of input Kannada poem. This tool also contains an exercise module to test the level of understanding of learners about metric analysis. Accuracy obtained by the proposed system is very good.

At present time the interest is growing considerably for theoretical and experimental analysis of back-scattered electrons (BSE) energy spectra.

In the last case it was shown theoretically that in order to obtain suitable depth resolution it is necessary to select a part of BSE flow with the directions of velocities close to inverse to the primary beam and energies within

Abstract:

An increase in the quantity and density of antenna elements increases the mismatched failure rate and measurement difficulty of the multiple-input multiple-output. To simplify the measurement method of the S11 parameter utilizing the traditional vector network analyzer, this article proposes a multiple-input multiple-output measurement method based on microwave imaging. The multiple-input multiple-output element was designed, and then the existence of mismatched scattering of the mismatched state through microwave one-dimensional and two-dimensional imaging simulations was verified.

Abstract:

This work explores various opportunities to improvise regular tasks done by college faculty viz. Exam Result Analysis, Daily Student Attendance Analysis and Lecture Schedule Storage. Result Analysis becomes a tedious task when handled through traditional pen-paper methods and spreadsheets. This can be simplified by using Classification and Regression techniques. Through Regression, module-wise clarity of subjects can be foretold for students. Classification and Clustering algorithms can help to segregate students in various groups so that additional efforts can be taken for slow learners. It c

Abstract:

In this paper a hybrid amplifier EDFA-RAMAN DWDM transmission system is proposed and demonstrated. A new hybrid two-stage optical fiber amplifier for dense wavelength division multiplexing (DWDM) network is observed. The hybrid amplifier is cascaded erbium- doped fiber amplifiers (EDFA) & Raman amplifier which provide a nearly flat gain over 80 nm. The hybrid amplifier has been modeled using an Optic-System version 14 on a DWDM transmission. In this paper we compare Q-factor at different input power i.e. at 0db and at 10 db. Here two different types of apodized function (Uniform & Gaus

Abstract:

Conventional moving‐window analyzers based on Fourier transforms sometimes lack the resolution required to separate each of the modes in a seismic waveguide. It is possible to enhance the resolution of a moving‐window analyzer by using a maximum entropy power spectral estimator to approximate the spectrum of each windowed segment of a trace. Barrodale and Erickson have developed a suitable maximum entropy algorithm which can also be applied to estimating the parameters required in the fast recompression of inseam seismic arrivals. The Barrodale‐Erickson maximum entropy algorithm appears to nee

AbstractA multi-octave receiver chain is presented for the use in a monolithic integrated vector network analyzer. The receiver exhibits a very wide frequency range of 1–32 GHz, where the gain meets the 3 dB-criterion. The differential receiver consists of an ultra-wideband low noise amplifier, an active mixer and an output buffer and exhibits a maximum conversion gain (CG) of 16.6 dB. The main design goal is a very flat CG over five octaves, which eases calibration of the monolithic integrated vector network analyzer. To realize variable gain functionality, without losing much input matching,

Techniques and equipment for ultrasonic preamplifier's noise performance evaluation are suggested. Equipment used and measurement technologies applied are described. One of the techniques suggested allows estimating the preamplifier noise with only impedance measurement results available. Sine wave correlation technique was used in the impedance measurement procedure. Another technique, not demanding the spectrum analyzer, was sug

Abstract:

Impedance spectrometry (IS) is a characterization technique in which a voltage or current signal is applied to a sample under test to measure its electrical behavior over a determined frequency range, obtaining its complex characteristic impedance. Frequency Response Analyzer (FRA) is an IS technique based on Phase Sensitive Detection (PSD) to extract the real and imaginary response of the sample at each input signal, which presents advantages compared to FFT-based (Fast Fourier Transform) algorithms in terms of complexity and speed. Parallelization of this technique has proven pivotal in mult

A portable optical-fiber spectrum analyzer operating in the visible and near-infrared range was used to measure in vivo the skin reflectance of lizards of the genus Podarcis. The investigations, which we performed in connection with a study of the biological problem of the microinsular melanism, are quite safe for the examined animals and can be easily extended to spectroscopic and/or energy input studies in other animals.
