Pseudo-random data are used to illustrate the relationship between errors in raw data being comparatively judged and the resulting Rasch pairs location parameters, first for data which are relatively homogeneous and second for data which have various amounts of heterogeneity. For each data type, various error sizes are used. Rasch location parameters are designed to be on an interval scale and are here demonstrated to be plotted on a more contracted scale when the objects are more homogeneous.

World is as of now concentrating on alternate material sources that are environment agreeable and biodegradable in nature. Because of the expanding natural concerns, bio composite produced out of regular fiber and polymeric resin, is one of the late advancements in the business and constitutes the present extent of experimental work. The use of composite materials field is increasing gradually in engineering. The composite consists of mainly two phases i.e. matrix and fiber. The accessibility of characteristic fiber and simplicity of assembling have enticed scientists worldwide to attempt by regional standards accessible inexpensive fiber and to learning their achievability of fortification determinations and to what degree they fulfill the obliged particulars of great strengthened polymer composite aimed at structural requisition. Fiber reinforced polymer composites has numerous preferences, for example, generally minimal effort of creation, simple to create and better quality contrast than perfect polymer tars due with this reason fiber strengthened polymer composite utilized within an assortment of provision as class of structure material. This work describe the fabrication and the mechanical behavior of banana fiber reinforced polymer composite at varying composition (25\%, 30\%, 35\%) with that of silicon carbide at 4\%, 8\%, 12\% respectively. Also the test such as the tensile test, hardness test and the bending test are carried out and the mechanical properties of the composite material are studied.

Each individual investor is different, with different financial goals, different levels of
risk tolerance and different personal preferences. From the point of view of investment management, these characteristics are often defined as objectives and constraints. Objectives can be the type of return being sought, while constraints include factors such as time horizon, how liquid the investor is, any personal tax situation and how risk is handled.

Our paper computationally explores Ricker’s predator satiation model with the objective
of studying how the extinction dynamics of an animal species having a two-stage lifecycle
is affected by a sudden spike in mortality due to an extraneous extreme event. Our
simulation model has been designed and implemented using sockeye salmon population
data based on a stochastic version of Ricker’s model; with the shock size being reflected
by a sudden reduction in the carrying capacity of the environment for this species. Our
results show that even for a relatively marginal increase in the negative impact of an
extreme event on the carrying capacity of the environment, a species with an otherwise
stable population may be driven close to extinction.

In this paper, we propose a new estimator for estimating the finite population mean using two
auxiliary variables. The expressions for the bias and mean square error of the suggested
estimator have been obtained to the first degree of approximation and some estimators are
shown to be a particular member of this estimator. Furthermore, comparison of the suggested estimator with the usual unbiased estimator and other estimators considered in this paper is carried out. In addition, an empirical study with two natural data from literature is used to expound the performance of the proposed estimator with respect to others.

This chapter presents the detailed discussion on the effect of non-response on the
estimator of population mean in a frequently used design, namely, stratified random
sampling. In this chapter, our aim is to discuss the existing allocation schemes in
presence of non-response and to suggest some new allocation schemes utilizing the
knowledge of response and non-response rates of different strata. The effects of proposed
schemes on the sampling variance of the estimator have been discussed and compared
with the usual allocation schemes, namely, proportional allocation and Neyman
allocation in presence of non-response. The empirical study has also been carried out in
support of the results.

Chakrabarty (1979), Khoshnevisan et al. (2007), Sahai and Ray (1980), Ismail et al. (2011) and Solanki et al. (2012) proposed estimators for estimating population mean Y. Up to the first order of approximation and under optimum conditions, the minimum mean squared error (MSE) of all the above estimators is equal to the MSE of the regression estimator. In this paper, we have tried to found out the second order biases and mean square errors of these estimators using information on auxiliary variable based on simple random sampling. Finally, we have compared the performance of these estimators with some numerical illustration.

go on to argue in favour of a neutrosophic adaptation of the standard 2x2 zero-sum game
theoretic model in order to identify an optimal outcome.

In this paper we have devised an alternative methodological approach for quantifying
utility in terms of expected information content of the decision-maker’s choice set. We
have proposed an extension to the concept of utility by incorporating extrinsic utility;
which we have defined as the utility derived from the element of choice afforded to the
decision-maker by the availability of an object within his or her object set. We have
subsequently applied this extended utility concept to the case of investor utility derived
from a structured, financial product – an custom-made investment portfolio incorporating
an endogenous capital-guarantee through inclusion of cash as a risk-free asset, based on the Black-Scholes derivative-pricing formulation.

The present chapter deals with the study of general family of factor-type estimators for estimating population mean of stratified population in the presence of nonresponse
whenever information on an auxiliary variable are available. The proposed family includes separate ratio, product, dual to ratio and usual sample mean estimators as its particular cases and exhibits some nice properties as regards to locate the optimum estimator belonging to the family. Choice of appropriate estimator in the family in order to get a desired level of accuracy even if non-response is high, is also discussed. The empirical study has been carried out in support of the results.

This paper is speculated to propose a class of shrinkage estimators for shape parameter
β in failure censored samples from two-parameter Weibull distribution when some ‘apriori’ or guessed interval containing the parameter β is available in addition to sample information and analyses their properties. Some estimators are generated from the proposed class and compared with the minimum mean squared error (MMSE) estimator. Numerical computations in terms of percent relative efficiency and absolute relative bias indicate that certain of these estimators substantially improve the MMSE estimator in some guessed interval of the parameter space of β ,
especially for censored samples with small sizes. Subsequently, a modified class of shrinkage estimators is proposed with its properties.

integral(cos[pi*I*x]x^(1/x),{x,1,a}) and
integral(sin[pi*I*x]x^(1/x),{x,1,a}), the limit of the ratio of a to a-1,as a goes to infinity is Gelfond's Constant, (e^pi).
We will consider that the hypothesis and provide hints for a proof using L'Hospital's Rule (since we have indeterminate forms as a goes to infinity).
We find we there is no limit of the ratio of the previous forms of integrals when the "I" is left out, and give a small proof for them.
