Abstract: Here an attempt is made to find positive numbers a,b and c such that an+bn=cn. Two cases were considered. an+bn is not divisible by (a+b)2 and an+bn is divisible by (a+b)2. From this a solution for the case n=3 is obtained as (9+5)3 + (9-5)3 = 123. A condition for finding such numbers for any n is also reached.

Abstract: Writing a standard scientific researchable paper be it project, technical report, dissertation or journal that reveal the application of science and technology to millennium challenges seems to be an herculean task among some scholars and students. Based on the above assertion, this paper critically examined the core aspect of a standard paper that is, methodology. Methodology is the framework and live-wire of any scientific paper. Hence, this paper takes a step to x- ray the components of methodology such as research design, study population, operational variables, sampling technique, and sample size determination, method of date collection and method of data processing/analysis with a view to harnessing the components together in their application for science and technology to millennium challenges.
Key words: research design, study population, sample size, data collection, variable(s) and methodology.

Abstract: The multinomial distribution has found applications in many practical situations that deal with a discrete random variable with k possibilities (k > 2). Interval estimation for the proportion parameter in a special case k = 2, the binomial distribution has been studied extensively in literature. However for k > 2, studies have focused the performance of estimation procedure mainly on coverage probabilities and yet there are other important aspects such as propensity of aberration in the limits of confidence intervals and computational issues. The present paper makes an attempt to look beyond coverage probabilities by marshalling the existing procedures in classical and Bayesian approaches for k > 2. To alleviate the computational issues, a comprehensive R program is also made available to facilitate the implementation of the procedures in both classical and Bayesian statistical paradigms.

Abstract: A double acceptance sampling plan for the life test truncated at the pre-assigned time to decide on acceptance or rejection of the submitted lots is considered. This double acceptance sampling plan uses only zero and one failure scheme. The probability model of the lifetime of the product is specified as Kumaraswamy-log-logistic distribution which contains several sub models. The minimum sample sizes of the first and second samples necessary to ensure the specified median life are obtained at the given consumer's confidence level. The operating characteristic values are analyzed with various ratios of the true median lifetime to the specified lifetime of the product. The minimum ratios of the median life to the specified life are also obtained so as to lower the producer's risk at the specified level. Numerical examples are provided to explain the application of sampling plan.

Title | : | A new argument for the non-existence of Closed Timelike Curves |
Country | : | India |
Authors | : | Sanath Devalapurkar |
: | 10.9790/5728-0744347 |
Abstract: In this paper, we attempt to present a short argument, different from that of the original proofs by that of Hawking, for a theorem stated that no closed timelike curves can exist. In a later paper, we apply this to quantum gravity and relate the curvature of spacetime to this theorem. Also, we present this paper as a preliminary introduction to the complete argument of this, and we also provide a preliminary notion of the concepts which will be narrated in the later papers. We also use this as a starting basis for a true theory of everything for a theory of everything. We use the notation of [1] and of [2].

Title | : | Modified Intrinsically Ties Adjusted Mann-Whitney U Test |
Country | : | Nigeria |
Authors | : | Oyeka I. C. A., Okeh U. M. |
: | 10.9790/5728-0745256 |
Abstract: This paper proposes to develop a ties adjusted or corrected approach to the usual Mann-Whitney U test that structurally makes provision for the correction of the U statistic and its variance for the possible presence of ties observation between the two sampled populations. The modification makes it unnecessary as is the case with the ordinary Mann-Whitney U test for the populations to be continuous with this method data analysis may precede without any problem when the populations are measurements on as low as the ordinal scale and may not be numerical. The method which is based on both magnitude and direction enables the estimation of the probabilities that a randomly selected subject from one population performs or scores higher, as well as or lower than a randomly selected subject from the other population. The procedure is illustrated with some sample data and shown to be at least as powerful as the modified median test and the usual Mann-Whitney U test.

Title | : | Generalized Method for Rank Determination in Rank-Ordered Statistics |
Country | : | Nigeria |
Authors | : | Oyeka I. C. A Okeh U. M. |
: | 10.9790/5728-0745761 |
Abstract: This paper proposes a generalized and structured method for use for rank determination in rank-order statistics. The sampled populations may be measurements on as low as the ordinal scale and need not be continuous or numeric. The proposed method would readily enable the researcher assign ranks to sample observations without the need to first arrange the observations in some form as is often the case with the traditional approach in the ranking of observations. The method also provides expressions that are intrinsically and structurally formulated to enable one easily break ties and assign appropriate ranks to any tied observations if need be in a straight forward manner. The proposed method is illustrated with some sample data and shown to be often easier to use in practice than the traditional method and of more generalized and wider applicability than some other existing formulations which are often limited in their use.

Abstract: This article is focused on the numerical investigation of a steady two-dimensional mixed convection boundary layer flow along a moving semi-infinite vertical plate. The plate is assumed to move with a constant velocity in the direction of the flow. The influences of thermophoresis and the thermal radiation are also included in the analysis. The governing boundary layer equations for the flow, thermal and species concentration fields are transformed into a non-dimensional form by a group of non-similar transformations. The resulting system of differential equations is solved by an implicit finite difference scheme in coupled highly nonlinear partial combination with the quasi-linearization technique. The effects of various parameters on the velocity and species concentration profiles and the wall thermophoretic deposition velocity are presented in terms of graphs. The present results are compared with previously published work and are found to be in excellent agreement.

Title | : | Modified Newton's method using harmonic mean for solving nonlinear equations |
Country | : | India |
Authors | : | J. Jayakumarand Kalyanasundaram M. |
: | 10.9790/5728-0749397 | |
Abstract: Different modifications in the Newton's method with cubic convergence have become popular iterative methods to find the roots of non-linear equations. In this paper, a modified Newton's method for solving a single nonlinear equation is proposed. This method uses harmonic mean while using Simpson's integration rule, thus replacing 𝑓 ′ 𝑥 in the classical Newton's method. The convergence of the proposed method is found to be order three. Numerical examples are provided to compare e the efficiency of the method with few other cubic convergent methods.
