This paper has put forward a decimal system based on binary system for representing figures of barcode image. Different with traditional distance of similar line unitary method, this paper invents the unitary decimalize method for EAN-13 image identification. Counting and sorting the times of the number that appears when scan the image to calculate the width of unit bar not use the averaging method, which has the same identification effect but more simple and effective. At last make the corresponding program to verify the method, the result shows this method performs well. It is not only suitable to the horizontal positive-going or reversed-going barcode image but also to the oblique barcode image.

The article describes a number of little-known methods for translating natural numbers from one number system to another. The first is a method for converting large numbers from the decimal system to the binary system, based on multiple divisions of a given number and all intermediate quotients by 64 (or another number equal to 2n ), followed by writing the last quotient and the resulting remainders in binary form. Then two methods of mutual translation of decimal and binary numbers are described, based on the so-called «Horner scheme». An optimal variant of converting numbers into the binary number system by the method of division by 2 is also given. In conclusion, a fragment of a manuscript from the beginning of the late 16th — early 17th centuries is published with translation into the binary system by the method of highlighting the maximum degree of number 2. Assignments for independent work of students are offered.

The seventh-grade students of the North Hills Joint Schools have found that there is fun as well as educational value in using the binary system. As all teachers of modern mathematics know, one of the main reasons for teaching the binary system is that the pattern for place value in this system is identical to that of the traditional decimal system. Developing the pattern in an entirely new situation gives the student a better understanding of the decimal system.

The teaching of place value is one of the most important—and possibly the most interesting—parts of the elementary mathematics program. You can show the children how you get another name for the number seven if you count in fives. And children will better understand what happens when you go from nine to ten and from ninetynine to one hundred in the decimal system if you discuss different bases with them. I have used the following technique for teaching the binary system in grades four to six.

PSR B1259-63 is a gamma-ray binary system hosting a radio pulsar orbiting around a O9.5Ve star, LS 2883, with a period of ∼3.4 years. The interaction of the pulsar wind with the LS 2883 outflow leads to unpulsed broadband emission in the radio, X-ray, GeV, and TeV domains. One of the most unusual features of the system is an outburst of GeV energies around the periastron, during which the energy release substantially exceeds the spin down luminosity under the assumption of the isotropic emission. In this paper, we present the first results of a recent multi-wavelength campaign (radio, optical, and X-ray bands) accompanied by the analysis of publicly available GeV Fermi/LAT data. The campaign covered a period of more than 100 days around the 2021 periastron and revealed substantial differences from previously observed passages. We report a major delay of the GeV flare, weaker X-ray flux during the peaks, which are typically attributed to the times when the pulsar crosses the disk, and the appearance of a third X-ray peak never observed before. We argue that these features are consistent with the emission cone model proposed by us previously, in the case of a sparser and clumpier disk of the Be star.

AbstractThe Algol-type eclipsing binary WX Eridani was observed on 21 nights on the 48-inch telescope of the Japal-Rangapur Observatory during 1973-75 in B and V colours. An improved period of P = 0.82327038 days was obtained from the analysis of the times of five primary minima. An absorption feature between phase angles 50-80, 100-130, 230-260 and 280-310 was present in the light curves. The analysis of the light curves indicated the eclipses to be grazing with primary to be transit and secondary, an occultation. Elements derived from the solution of the light curve using Russel-Merrill method are given. From comparison of the fractional radii with Roche lobes, it is concluded that none of the components have filled their respective lobes but the primary star seems to be evolving. The spectral type of the primary component was estimated to be F3 and is found to be pulsating with two periods equal to one-fifth and one-sixth of the orbital period.
