  • Bioequivanence models arise typically in bioassays when new preparations are compared against standard ones by means of responses on some biological organisms. Relative potency measures provide nice interpretations for such bioequivalence and their estimation constitutes the prime interest of such studies. A conditional quantile process based on the k-nearest neighbor method is proposed for this purpose. An alternative procedure based on Kolmogrov-Smirnov type estimator has also been considered along with. ARIC ultrasound data are analyzed as examples.

  • The purpose of this study is to establish the function of a sub-system for System Alternatives Feasibility Estimation (SAFE) in R & D Project Planning Phase (RDPPL). It is the fundamental function of the RDPPL/SAFE that selected an optimal planning system alternative of all, considered at RDPPL/SAS, by logical means in view of feasibility. In this paper, improving the function of RDPPL/SAFE, mathmatical models in order to quantify methods determining and integrating the feasibility funtion in each terminal system with a multi-stage process are examined.

  • Non-Stationary transition probabilities models which is incorporated into a Markov framework with exogenous variables to account for some of variability are discussed, and extended for alternative procedure. Also as an application of the methodology, the size change of aggregate time-series data on the planted system of agricultural crops is estimated, and evaluated for the precision of time-varying evolution statistically.

  • A new model which is able to understand the mechanical behavior is developed, based on investigating the theoretical background for design compressive strength in strut-and-tie model. A proposed model is an alternative method for engineers through analyzing the merits and demerits of the conventional models

  • In this note, companion to the paper [10], we describe an alternative method for finding Laurent polynomials mirror-dual to complete intersections in Grassmannians of planes, in the sense discussed in [10]. This calculation follows a general method for finding torus charts on Hori-Vafa mirrors to complete intersections in toric varieties, detailed in [5] generalising the method of [8].

  • The two-sample t-test is not expected to be optimal when the two samples are not drawn from normal populations. According to Box and Cox (1964), the transformation is estimated to enhance the normality of the tranformed data. We investigate the asymptotic relative efficiency of the ordinary t-test versus t-test applied transformation introduced by Yeo and Johnson (1997) under Pitman local alternatives. The theoretical and simulation studies show that two-sample t-test using transformed date gives higher power than ordinary t-test for location-shift models.

  • Many computational models using computer program in agricultural engineering were proposed and introduced until now. These programs were developed based on procedure and structural program paradigm, so it's hard to reuse because programs become bigger and complex. In this study proposals a program paradigm that is easy to combine and reuse. Embedded engineering techniques are Java, JavaBean model, object-oriented programming.

  • Rail transport has grown over the Past decades, and rail networks have highly concentrated in urban area, and it is possible for rail passengers to choose a route anions a number of alternative routes. Analysis of factors influencing the choice of route, are required to estimate the rail travel demand of each route. In this paper, we describes route choice model for the transit assignment and characteristics of the route choice(i.e., by relative travel time and fares), and attempts to estimate travel demand of new rail transit based on the slated preference(SP) survey data of Nanko Porttown, which is located in Osaka, Japan.

  • 본 연구에서는 통신산업에서 사용되는 비용추정 방법론을 조명하고, 새로운 방법론을 제시하고 있다. 통신산업에서 적정 비용산정작업은 매우 중요한 작업 중 하나이지만, 전통적인 산업과 달리 통신산업 특유성질로 인하여 비용산정이 매우 힘든 것이 사실이다. 본 연구에서는 기존의 비용추정방법과 다르게 Neural Network Model을 비용추정방법으로 사용함으로써 통신산업 비용추정기법으로 간단하고 이론적 측면에서 더 적합한 방법을 제시하였다.

  • We consider the problem of testing for outliers in generalized linear model. We proceed by first specifying a mean shift outlier model, assuming the suspect set of ourliers is known. Given this model, we discuss standard approaches to obtaining score test for outliers as an alternative to the likelihood ratio test.
