An ejector system is to be designed in order to pump out the gasses from low pressure to ambient conditions. Ejectors mainly use the principles of fluid dynamics for pumping. They do not consist of any mechanical parts and hence no wear and tear. But consequently the design of the ejectors should be very much precise for the proper and reliable function. In this part of the work, the configuration of a nozzle is calculated from a predefined rocket air ejector configuration. Models are developed...

Efficient consumption of energy resources and minimizing relevant costs are both substantial issues that not only don’t fade into insignificance by time but also have turned out to be essential concerns due to energy crisis and recent price rises in fuel carriers. Recently, much more efforts are made to develop modern systems do decrease the amount of energy consumption and relevant costs regarding to the problems of energy and environmental pollution. Combined Heat and Power (CHP) is one of...

Formal analysis of security protocols is largely based on a set of assumptions commonly referred to as the Dolev-Yao model. Two formalisms that state the basic assumptions of this model are related here strand spaces and multiset rewriting with existential quantification. Strand spaces provide a simple and economical approach to analysis of completed protocol runs by emphasizing causal interactions among protocol participants. The multiset rewriting formalism provides a very precise way of...

The control of CO2emissions released in the atmosphere is an indisputable need in order to avoid environmental and health consequences, as well as to reach European and global targets for climate change confrontation. During the last decades, various methods have been proposed towards this direction. As fossil fuels remain dominant in the energy field, technologies focused on CO2capture have been developed, known as Carbon Capture Systems (CCS). During the last decade, CCS have managed to...

Parameterization of textures can be useful for detection of textual similarities and matching. In this project we have developed stochastic model to generate a set of parameters from the texture image domain and frequency domain. This model is aimed at quantification of textures for detection of similarities differences. Our attention has been concentrated on the parameterization of mottled textures. To test the model we have used it to generate texture images back from the parameters obtained...

In order to evaluate our methods and approaches of estimating the operating characteristics of discrete item responses, it is necessary to try other comparable methods on similar sets of data. LOGIST 5 was taken up for this reason, and was tried upon the hypothetical test items, which follow the normal ogive model and were used frequently in testing our own methods and approaches. Two sets of simulated data we used based upon 500 and 2,000 hypothetical examines, respectively. It was found out...

In this report we define poly-optimal confidence intervals for a location-parameter. The formulas are given for the case of two shapes, but can easily be extended to the case of many shapes. For the case of two situations, the Gaussian and the slash, the resulting family of confidence interval estimators is examined. These interval estimators are competitors of existing so-called robust procedures. A comparison to a few of these is included. (Author)

We develop a campaign model for counterinsurgency that is derived from the Lanchester-inspired Vidale-Wolfe marketing model utilized in the analysis of a consumer population's dynamics. We adapt this approach for a situation in which the output of our differential equation model is not attrition but the percentage of a given population that supports a particular side in the insurgency. The model is descriptive, providing a structured framework to analyze complex inputs in a simple,...

Mediation analysis aims to uncover causal pathways along which changes are transmitted from stimulus to response. Recent advances in causal inference have given rise to a general and easy-to-use estimator for assessing the extent to which the effect of one variable on another is mediated by a third, thus setting a causally-sound standard for mediation analysis of empirical data. This estimator, called Mediation Formula, is applicable to nonlinear models with both discrete and continuous...

In this Note we extend the Empirical Interpolation Method (EIM) to a regression context which accommodates noisy (experimental) data on an underlying parametric manifold. The EIM basis functions are computed Offine from the noise-free manifold; the EIM coefficients for any function on the manifold are computed Online from experimental observations through a least-squares formulation. Noise-induced errors in the EIM coefficients and in linear-functional outputs are assessed through standard...

Small underground nuclear explosions need to be confidently detected and identified in regions of the world where they have never before occurred. We are developing a parametric model of the nuclear explosion seismic source spectrum derived from regional phases (Pn, Pg, Sn, and Lg) that is compatible with earthquake-based geometrical spreading and attenuation. Earthquake spectra are fit with a generalized version of the Brune spectrum, which is a three-parameter model that describes the...

Let T be an operator defined on the subset U of a Banach space X determined by equality or inequality constraints for a finite number of functionals on X. The necessary conditions that the solution of the minimization problem must satisfy is determined. A case of particular interest is when T has values in L(infinity). Several examples in detail are analyzed to show how the necessary conditions yield detailed information about the solution. The notion of a t-point is introduced and how the...

Consider the lifelengths T sub 1,...., T sub k of k components subjected to a randomly varying environment. They are dependent on each other because of their common dependence on the environment. The parameters of the model are the distribution of the random process which describes the environment and a set of rate functions which determine the probability law of T sub 1,..., T sub k as a function of the distribution of the environment. We find conditions on the parameters of the model which...

In reliability growth models, systems undergo an improvement in performance during prototype testing, as design changes are made, and operating procedures and environment are modified. In the learning-curve models, this improvement occurs continuously over time, and there is great interest in predicting the ultimate performance of the system, using only the epochs of the failures which occur early in the testing program. This paper constructs a general framework in which to analyze this...

The goal of this project was to develop new techniques for the construction, description, and analysis of multi-agent systems. The characteristics of systems being addressed include a high degree of non-determinism (resulting form a large number of interactions) and unpredictability of the environment in which the agents operate. Specifically, we implemented tools for building robust and dependable large-scale multi-agent systems and studied methods for predicting and analyzing the behaviors of...

A class of parametric models, called splitting processes, is defined, using de Finetti's concept of adherent mass. Such splitting processes give rise to complex mixtures of distributions. It is proved that the nonparametric Bayesian predictive procedure, A sub n, of Hill (1968), holds exactly for a member of this class called a nested splitting process. It is also shown that the generalization of A sub n, called H sub n, to deal with ties, can hold exactly. A multivariate version of A sub n,...

Parametric approximation of curves offers the possibility of increasing the order of approximation by using the additional parameters in the parameterization of the curve. This has been studied in several papers, see e.g.,. The resulting problems are highly nonlinear. Here the cases of approximation order O(h(sup 8)) are studied which need piecewise quartic curves in the plane and piecewise quintic curves in space.

In Balanced Incomplete Block Designs the presence of outliers in the data not only indicate non-normality, so that classical methods of analysis on the data are inappropriate, but also diminish the power of classical methods of analysis that assume normality of the data. One alternative is to use Durbin's nonparametric test. This research examined a rank transformation approach where all the data are ranked from smallest to largest, over all treatments and blocks. Then the usual F-test is...

Functional programming languages incorporate a number of powerful features, including advanced polymorphic type systems and first-class, higher-order functions. However, these important features have had little effect on popular imperative languages such as C. As part of the Advanced Type Systems Project at NPS, a dialect of C called Polymorphic C has been designed which integrates an advanced polymorphic type system into C. In order to implement full parametric polymorphism while retaining the...

The main contribution of this paper is a formal semantics for restrict and a type and effect system for checking that restrict-annotated programs are correct with respect to our semantics. We give an efficient inference algorithm for our type system and describe natural extensions of our type system to include subtyping, parametric polymorphism, and affects...

Consider a heteroscedastic linear regression model with normally distributed errors in which the variances depend on an exogenous variable. Suppose that the variance function can be parameterized as psi(z sub i, theta) with theta unknown. If theta is any root-N consistent estimate of theta based on squared residuals, it is well known that the resulting generalized (weighted) least squares estimate with estimated weights has the same limit distribution as if theta were known. The covariance of...

Trajectory Mapping 'TM' is a new scaling technique designed to recover the parameterizations, axes, and paths used to traverse a feature space. Unlike Multidimensional Scaling (MDS), there is no assumption that the space is homogeneous or metric. Although some metric ordering information is obtained with TM, the main output is the feature parameterizations that partition the given domain of object samples into different categories. Following an introductory example, the technique is further...
