Constraining Pictures with Pictures

This paper presents a visual language called Miro for specifying and restricting operating system security configurations. A Miro picture specifies exactly what rights users have on files. A Miro constraint, also stated visually, restricts the set of Miro pictures which are considered legal. Such constraints on pictures give an exact specification of security policies and a practical method for...

functional study of p0 proteins of two cereal yellow dwarf viruses (cydv-rpv and cydv-rps) and identification of their cellular partner

نقش سرکوبگری پروتئین p0 در دو پولروویروس کوتولگی زردی غلات cydv-rpv) و (cydv-rps، متفاوت در شدت بیماریزایی، مورد مطالعه قرار گرفت. نتایج نشان داد که هر دو پروتئین p0 p0cy-rpv) و (p0cy-rps قادر به سرکوب خاموشی آر ان ای ایجاد شده توسط ترادف های تراژن سنس و تکرار معکوس در n. benthamiana هستند. نشان داده شد که هر دو پروتئین p0 می توانند تخریب پروتئین argonaute-1 را تسهیل کنند. علاوه بر این، تمایل م...

Polynomial Representation of Pictures

In many image processing applications, the discrete values of an image can be embedded in a continuous function. This type of representation can be useful for interpolation, geometrica! transformations or special features extraction. Given a rectangular M x N discrete image (or sub-image), it is shown how to compute a continuous polynomial function that guarantees an exact fit at the considered...
