A complete theory of aeroacoustics of homentropic fluid media is developed and compared with previous theories. The theory is applied to study the interaction of sound with vortex flows, for the DC9 in a standard takeoff configuration. The maximum enginewake interference noise is estimated to be 3 or 4 db in the ground plane. It is shown that the noise produced by a corotating vortex pair departs significantly from the compact M scaling law for eddy Mach numbers (M) greater than 0.1. An...

Consider a GI M 1 queue with set up period and working vacations. During the working vacation period, customers can be served at a lower rate, if there are customers at a service completion instant, the vacation can be interrupted and the server will come back to a set up period with probability or continue the working vacation with probability , and when the set up period ends, the server will switch to the normal working level. Using the matrix analytic method, we obtain the steady state...

The performance of several beamlike dynamic vibration absorbers is analyzed and, in one case, confirmed by experiment. The dynamic absorbers are employed to suppress the transmissibility at resonance across a simple massspring vibrator, a stanchion, and a simply supported rectangular panel. The absorbers comprise either single or double cantilever beams that are mass loaded at their free ends, or clampedclamped beams that are centrally mass loaded. Generally, the beams provide both the...

Multivariate models with positively correlated components have found wide applicability in reliability and biostatistics. Perhaps the best known and most widely used such model is the multivariate exponential distribution due to Marshall and Olkin (JASA, 1967). We study a discrete analogue of the latter model. Specifically, we consider a model for random vecotrs Y whose components are positively correlated and have Bernoulli marginal distributions. The construction ofthe model reflects the fact...

The negative binomial distribution arises in probability as the distribution of the waiting time to achieve a specified number of successes in a sequence of Bernoulli trials. In addition, it has been widely used in statistics as a model for a variety of data involving counts. Multivariate analogues of the negative binomial distribution are of interest as joint distributions of waiting times in Bernoulli trials and for modelling data involving pairs or mtuples of possibly dependent counts. This...

A general theory of aerodynamic sound is developed. The basic equations of fluid mechanics are expressed in terms of velocity, enthalpy and entropy, and the velocity field is separated into irrotational and rotational parts with the latter being incompressible. A fundamental new concept, Bernoulli enthalpy, H, is introduced, again by analogy with homentropicirrotational flow. It is shown that the source of the radiative sound field is the substantive rate of change of the Bernoulli enthalpy....

Analytical models applicable to hydrodynamic ram studies are reviewed. These include Stepka and Morse's observations of shock formation, Yurkovich's analysis of the shock, and Lundstrom's analysis of the fluid drag pressures. Several approaches to the wall analysis are also reviewed; these include Chou's use of the method of characteristics, and Ball's adaptation of piston theory. Finally, damage reduction methods are also discussed. (Author)

An accurate and yet simple Meshless Local PetrovGalerkin (MLPG) formulation for analyzing beam problems is presented. In the formulation, simple weight functions are chosen as test functions. The use of these functions shows that the weak form can be integrated with conventional Gaussian integration. The MLPG method was evaluated by applying the formulation to a variety of patch test and thin beam problems. The formulation successfully reproduced exact solutions to machine accuracy when test...

In earlier work (Mantel & Bilger, 1994) the structure of the turbulent premixed flame was investigated using statistics based on conditional averaging with the reaction progress variable as the conditioning variable. The DNS data base of Trouve and Poinsot (1994) was used in this investigation. Attention was focused on the conditional dissipation and conditional axial velocity in the flame with a view to modeling these quantities for use in the conditional moment closure (CMC) approach to...

System matrices for EulerBernoulli beam problems for the meshless local PetrovGalerkin (MLPG) method deteriorate as the number of nodes in the beam models are consistently increased. The reason for this behavior is explained. To overcome this difficulty and improve the accuracy of the solutions, a local coordinate approach for the evaluation of the generalized moving least squares shape functions and their derivatives is proposed. The proposed approach retains the accuracy of the MLPG methods.

The properties of the actuator to sensor transfer functions for various shaped strain actuatorsensor pairs on a BernoulliEuler beam are investigated. Analytical expressions for these transfer functions and their associated dereverberated transfer functions are derived. It is shown that the actuatorsensor pair can be designed such that its dereverberated transfer function will have a desirable corner frequency and high frequency rolloff rate. The analytical and dereverberated transfer...

A procedure for finding a confidence interval for the reliability, P, of a multicomponent device is presented which utilizes Bernoulli test data pertaining to the component parts. In particular, Bernoulli trials are carried out for part of a system built up from k different parts. On the basis of the number of observed failures an interval estimate of the reliability (or probability of functioning) of the system is constructed. In the series case, with k parts, the minimum and maximum of P (as...

We consider several classes of interfering queues that appear in packetradio networks. We analyse the class of systems where one of the queues is given full priority and obtain an expression for the joint probability distribution of the queue lengths. For ALOHAtype systems with two symmetric queues we calculate the average packet waiting time and queue lengths and for symmetric systems with an arbitrary number of subscribers we develop a method to approximate these quantities. The...

In the analysis of a packetized communication system such as a slotted ALOHA, one needs to deal with discretetime point processes and related queues. We examine how Poisson processes, M/M/1 queue, M/G/infinity, etc., should be translated in their discretetime versions. We then give a new definition of processorsharing and its properties. Correlation functions of input and output processes in an M/G/infinity are also studied. (Author)

Some of the simpler methods in current use for analyzing ballistic impacts by long rod penetrators are reviewed and critiqued. In spite of several obvious shortcomings the eroding rod model has been used as a starting point and guide for an experimental investigation of penetration phenomena. Some of the principal results of that program are reviewed, and several areas for future work are identified. Carefully developed, time resolved data of the types described in this report should serve as a...

LQG compensator control of transverse vibrations was implemented on an aluminum cantilevered beam in a smart structure paradigm. The beam was mounted with two selfsensing, selfactuating piezoceramic patches. The EulerBernoulli beam equation was discretized via a Galerkin type approximation (referred to as the full order model). To reduce the size of the resulting finite dimensional approximating system, the Proper Orthogonal Decomposition (POD) was employed as a reduced basis method. A...

Wind tunnel measurements and calculations of the aerodynamic interactions between two tiltrotor aircraft in helicopter mode are presented. The measured results include the roll moment and thrust change on the downwind aircraft, as a function of the upwind aircraft position (longitudinal, lateral, and vertical). Magnitudes and locations of the largest interactions are identified. The calculated interactions generally match the measurements, with discrepancies attributed to the unsteadiness of...

Increasing power density is a daunting challenge for continued MOSFET scaling due to nonscalability of the thermal voltage kBT/q. To circumvent this CMOS power crisis and to allow for aggressive supply voltage reduction alternative switching device designs have been proposed and demonstrated to achieve steeper than 60mV/dec subthreshold swing (S). This dissertation begins with a general overview of the physics and operation of these MOSFETreplacement devices. It then applies circuitlevel...

A critical review of the eroding rod model for deep penetration by long rods is presented. The chief difficulty lies in the use of the modified Bernoulli equation and of the oversimplified rigidplastic material model, which is implied by that equation. It is concluded that even though the eroding rod model can give only limited insight into the details of the actual rod/ target interaction, still it is useful in suggesting an experimental program to begin probing the details of the...

This thesis compares the performance and robustness of colocated and noncolocated sensor/actuator pairs. Linear quadratic Gaussian and loop transfer recovery (LOG/LTR) procedures are used to design optimum controllers for three example problems. The first example is a single motion degreeoffreedom system having motion only about one axis. This type of system does not have any right half plane zeros for the noncolocated case; however, the thesis shows it behaves as a non minimum phase...

Como ciencia, está basada en un compromiso adecuado entre teoría y experimentación. Por ser la Mecánica de Fluidos una rama de la mecánica, dispone de un conjunto de leyes de conservación bien documentadas y es posible, por tanto, un tratamiento teórico riguroso. Sin embargo, la teoría es a veces frustrante, porque se refiere principalmente a ciertas situaciones idealizadas que pueden no ser válidas en los casos prácticos. Los dos obstáculos mayores para el tratamiento teórico son...

This work aimed at solving issues in distributed machine learning. The PI's team proposed three directions to work on. First, they designed solutions to speed up the alternating direction method of multipliers (ADMM) for distributed data. Second, they focused on a clientserver learning scenario in which an online, semisupervised learning approach is designed to reduce the communication load. Finally, the team proposed the parallel leastsquares policy iteration (parallel LSPI) to parallelize...

A simplified uniaxial strain controlled creep damage law is deduced with the use of experimental observation from a more complex strain dependent law. This creep damage law correlates the creep damage, which is interpreted as the density variation in the material, directly with the accumulated creep strain. Based on the deduced uniaxial strain controlled creep damage law, a continuum mechanical creep rupture analysis is carried out for a beam resting on a high temperature elastic (Winkler)...

The basic theory of aeroacoustics of homentropic fluid media is applied to the problems of sound scattering, production, and stimulated emission. A general theory of scattering from low speed threedimensional vortex flows is presented. Specific results are given for the horseshoe vortex and vortex ring. The noise of an elementary corotating vortex pair in various flows is calculated. It is shown that a potential flow and shear flow can substantially increase the basic pair noise. Small reverse...

Rodbeam theories are founded on hypotheses such as Bernouilli's suggesting flat crosssections under deformation. These assumptions, which make rodbeam theories possible, also limit the accuracy of their analysis. It is shown that from a certain order upward terms of geometrically nonlinear deformations contradict the rodbeam hypotheses. Consistent application of differential geometry calculus also reveals differences from existing rod theories of higher order. These differences are...
