Data are rarely perfect. Whether the problem is data entry errors or rare events. Outliers have two opposing properties. They can be noises that disturb regression and classification task. On the other hand, they can provide valuable information about rare phenomena, which can le...

A data compression algorithm is a signal processing technique used to convert data from a large format to one optimized for compactness. Huge volumes of fingerprint images that need to be transmitted over a network of biometric databases are an excellent example of why data compr...

A generalization of Run-length-limited (RLL) codes has been introduced and its dynamical properties as a symbolic dynamical system under the shift map will be investigated. A formula for entropy and zeta function will be given and when our system is shift of finite type, its Bowe...

For the first time ever, this work formulates definition of the degree of order for the non-random sequence of elements. Earlier, the only known parameter to evaluate a system’s degree of order was entropy. It has been shown that using entropy to evaluate the degree of order in d...

For a connected graph G, a subset S = {s1, s2,...., sk} of vertices of G and each vertex x of G we associate a pair of k-dimensional vectors (u,v), where u = (d(x, s1), d(x, s2),...., d(x, sk)) and v = (δ(x, s1), δ(x, s2),...., (x, sk)), where d(x, si) and δ(x, si) respectively d...

The designer of pipes normally faces the problems of how to design and prevent the pipes from leakage when used. To eradicate of reduces this problems, effects of retarding force on mass flow rate must take into consideration by compare the retarding force, mass flow rate of flui...

This work presents the application of the power series method (PSM) to find solutions of nonlinear delay differential equations of pantograph type (PDDEs). Three equations are solved to show that PSM can provide analytical solutions of PDDEs in convergent series form. The nonline...

Background: In vaccination studies with complex sample survey, survival functions have been used since 2002. Recent publications have proposed several methods for evaluating the adjusted survival functions in non-population-based studies. However, alternative methods for calculat...
