... formed. B specifies how often a representative vector of weight t is covered by the vectors in a given orbit of weight w. Orbits of weight w for which the corresponding row of B contains an entry ... indicates a new best result. The meaning of the annotations is given in the Key. The tables show the relative merits of the general algorithms in terms of the number of codewords g...

... the study of boundary layer flow and heat trans- fer over a stretching surface has achieved a lot of success because of its large numb er of applications in industry and technology. Few of these ... plotting h-curve. The effects of pertinent parameters of nanofluid have been discussed through graphs. 2 Formulation of the problem Consider the steady two-dimensional flow of an inc...

... monitoring techniques. Because of its novelty, the proposed technique has various potential extensions, such as recognition of various classes of vehicles, development of a traffic surveillance network ... simplest form of a Bayesian network [53]. Another advantage of the naive Bayes classifier is that it only requires a small amount of training data to estimate the parameters (mea...

... 0, 0 ≤ j ≤ n. Then the solution of (4.4) and (4.5) is bounded if and only if the condition (5.5) is satisfied. Proof. The proof is immediate consequence from proof of Theorem 4.3 with Remark 5.1. Remark ... condition for the boundedness of all solutions of (1.1) and the scalar case of (1.1), respectively. The next result provides a sufficient condition for the boundedness of solution...

... Introduction The topic of the problem of finite or infinite beams which rest on an elastic foundation has received increased attention in a wide range of fields of engineering, because of its practical design ... norm of the resulting beam deflection cannot be too large compared to that of the input loading w. Meanwhile, the nonlinearity and the non-uniformity of the system sugges...
