We extend the notion of regular sequence ([Mac16]) to overdetermined system of algebraic equations. We study generic properties of Gröbner bases and analyse precisely the behavior of the F5 [Fau02] algorithm. Sharp asymptotic estimates of the degree of regularity are given. We consider polynomials (f1, . . . , fm) in k[x1, . . . , xn] where k is a field. In this extended abstract, we restrict a...
زمینه مطالعه: فیمبریه باکتری f5 ( k99) e. coli مهمترین و شایعترین عامل چسبنده ای که تاکنون برروی سویه های اشریشیا کلی درگیر در اسهال گوساله هاشناخته شده است. این باکتری از طریق توکسین های مقاوم حرارتی (st) سبب اسهال در گوساله های تازه متولد شده می شود. با افزایش نگرانی در مورد گسترش مقاومت های آنتی بیوتیکی، یافتن راه حل جایگزین مانند استفاده از کلی سین ها ضرورت دارد. کلی سین ها ترکیبات آنتی ب...
This paper compares the XL algorithm with known Gröbner basis algorithms. We show that to solve a system of algebraic equations via the XL algorithm is equivalent to calculate the reduced Gröbner basis of the ideal associated with the system. Moreover we show that the XL algorithm is also a Gröbner basis algorithm which can be represented as a redundant variant of a Gröbner basis algorithm F4. ...
Wrightia tinctoria is a constituent of several ayurvedic preparations against skin disorders including psoriasis and herpes, though not yet has been explored for anticancer potential. Herein, for the first time, we report the significant anticancer properties of a semi-purified fraction, DW-F5, from the dichloromethane extract of W. tinctoria leaves against malignant melanoma. DW-F5 exhibited a...
fuzzy time series have been developed during the last decade to improve the forecast accuracy. many algorithms have been applied in this approach of forecasting such as high order time invariant fuzzy time series. in this paper, we present a hybrid algorithm to deal with the forecasting problem based on time variant fuzzy time series and particle swarm optimization algorithm, as a highly effici...
Increased popularity of digital media and image editing software has led to the spread of multimedia content forgery for various purposes. Undoubtedly, law and forensic medicine experts require trustworthy and non-forged images to enforce rights. Copy-move forgery is the most common type of manipulation of digital images. Copy-move forgery is used to hide an area of the image or to repeat a por...
Let K be a field equipped with valuation. Tropical varieties over can defined theory of Gröbner bases taking into account the valuation K. Because use valuation, tropical has proved to provide settings for computations polynomial rings p-adic that are more stable than classical bases. Beforehand, these strategies were only available homogeneous polynomials. In this article, we extend F5 strateg...
the purpose of this paper is to show that the ideas and techniques of the classical methods of finding stability, such as the criteria of leonhard and nyquist, can be used to derive simple algorithm to verify stability. this is enhanced by evaluating the argument of the characteristic equation of a linear system in the neighbourhood of the origin of the complex plane along the imaginary axis
We present some results on almost maximum distance separable (AMDS) codes and Griesmer codes of dimension 4 over F5. We prove that no AMDS code of length 13 and minimum distance 5 exists, and we give a classification of some AMDS codes. Moreover, we classify the projective strongly optimal Griesmer codes over F5 of dimension 4 for some values of the minimum distance.
