For the image of 512×512,the time of two-dimensional FFT by fixed DSP is 17.7 ms, the gross time of float point multiplication and division by float point DSP is 32.51 ms, according to above time, the load of every DSP is calculated.
At first, a fast polynomial division algorithm is developed in this paper at O (nlog_2m) times, where, n, mare degrees of dividend and divisior polynomial, respectively,We then discuss a fast interpolation algorithm through n+1 points that extends n+1with power of two to any number, the running times is O(n log_2~2n).
A problem of a 0-1 polynomial programming is transformed into that of a 0-1 polynomial programming, in which the degree of each variable is not larger than 1, by the multivariable division algorithm.
Results: The students in 4 - 6 grades could not only finish all items of the subtests RA, RS, RM, RD, EG, CK within the time limit but also had all items correct at 34.89 % ,29.10% , 15.34% ,46.56 % ,2.65 % ,37.57 % respectively and their scores in these subtests were better than that in Germany, but so weren' t the scores in other subtests.
Methods Twelve cases of anaphylatoid purpura nephritis were enrolled in the study and divided into 2 groups. After failure in the hormone′s treatment,the observation group was applied with intermittent eliminating white blood cells(5 mL/kg,1-2 times/week),and the control group was treated with immunosuppressive agents[cyclophosphamide(CTX) 0.8-1.0 g/m~2,or methotrexate(MTX) 8-10 g/m~2].
For example, if our groupG isSn, these objects are field extensions; ifG=On, they are quadratic forms; ifG=PGLn, they are division algebras (all of degreen); ifG=G2, they are octonion algebras; ifG=F4, they are exceptional Jordan algebras.
We show that the absolute invariants (i.e.,the ${\mbox{\rm GL}}(2, {\mbox{\bf R}})$-invariants in the field of fractions of ${\mathcal P}$) distinguish the isomorphism classes of 2-dimensional non-associative real division algebras.
By the way, the methods usually used in the study of cyclicity of polycycles such as derivation division algorithm, Khovanskii procedure and the method of critical point analysis are introduced.
A tabulation method for solving n simultaneous linear equations is given. For the general type, it requires(1/3)n(n-1)(n-2)+(5/2)n(n-1)+n multiplications or divisions. For n three-moment equations, it requires only 6n-5 multiplications or divisions.A slide rule can be used with advantage for working out this tabulation and the small error thus introduced can be corrected, if necessary, by a second tabulation using the coefficients computed in the first.
In this paper, the construction and some optimal problems of initial factor table in high-speed iterative divisions are discussed. A number of the smallest and shortest initial factor tables in various cases are given, the sufficient and necessary condition for existence of these tables and their construction methods are shown. For any expected accuracy, we have obtained the relation between the size of table (i.e., number of elements in the table) and the length of elements (i.e., number of bits in an elem...
