ABSTRACT
Extreme acceleration maneuvers encountered in modern agile fighter aircraft can wreak havoc on human physiology thereby significantly influencing cognitive task performance. Increased acceleration causes a shift in local arterial blood pressure and profusion causing declines in regional cerebral oxygen saturation. As oxygen content continues to decline, activity of high order cortical tissue reduces to ensure sufficient metabolic resources are available for critical life-sustaining autonomic functions. Consequently, cognitive abilities reliant on these affected areas suffer significant performance degradations.

This goal of this effort was to develop and validate a model capable of predicting human cognitive performance under acceleration stress. An Air Force program entitled, “Human Information Processing in Dynamic Environments (HIPDE)” evaluated cognitive performance across twelve tasks under various levels of acceleration stress. Data sets from this program were leveraged for model development and validation.

Solar Autoclaves for Rural Health Clinics in Developing Nations
An ASME Dayton Section / WSU Student Section Social Event

Our featured speaker will be Maria Fullenkamp, Vice President of the WSU Student ASME Chapter. She will speak about her summer service learning project in Nicaragua. Currently rural health clinics in Nicaragua travel once a week by bus to sterilize their medical equipment. Because of their limited amount of sterilized medical utensils, these rural health clinics often face the decision of whether to use contaminated medical equipment, or simply to turn patients away. To address this problem, this summer she will be traveling to rural Nicaragua to test solar autoclaves through a group called ETHOS (Engineers for Technical Humanitarian Opportunities for Service-Learning). The solar autoclave design has been developed by another ETHOS student and this summer she will be testing this device with three other ETHOS students and eventually they plan to implement the solar autoclave in Sabana Grande, Nicaragua as well as other developing countries facing the same problem.

Maria will speak for about half an hour, and an informal pizza social will follow.

Come support this unique public service project!

If you have any questions, please feel free to contact Maria Fullenkamp at fullenkamp.25@wright.edu

ABSTRACT
There is no doubt that nature has existed as the very inspiration for many of technological achievements of today. Flight is no exception though our conventional methods of flight seem to be completely devoid of any flapping modes commonly seen in insects and birds. This is because the unsteady characteristics of natures keen flight capabilities is very difficult to study. However, as our computational and experimental methods of investigation have improved, our imagination again begins to turn to this one aspect of flight that has eluded man thus far. Birds and more specifically insects are capable of flying at such slow speeds and on such small scales that man’s understanding of aerodynamics begins to breakdown and fails to account for the force necessary for insects to fly. This has led to serious complications in the design of a small semi-autonomous flying robot or Micro Air Vehicle (MAV) that the military as well as a few civilian organizations have high interest in for multiple purposes.

This report uses a user-defined computational Navier Stokes solver, called Vicar3d, as well as information from an experimental facility to test some basic concepts inherent to flapping foils such as the ability of the angle of attack to predict either interaction with the airfoil and the wake and/or the loads history. Also, whether the selection of the airfoils has any effect on the wake or loads history as well, mainstream flapping foil literature has mainly concentrated on using conventional airfoils commonly employed in fixed wing aircraft. It was the intention of the author of this report to test airfoils that were shaped from actual cross-sections of actual insect species as these foils have shown greater performance in static testing. Additionally, some interesting phenomena was discovered along the course of these studies and an unconventional type of flapping motion resulted that was studied to determine possible applications to MAVs with the motions’ higher performance capabilities.

It was found that the existing definition of the effective angle of attack for a flapping foil is either erroneous or simply insufficient information to predict either wake interaction or loads history with no obvious relationship between the angle of attack and loads time traces. Finally, the proper selection of airfoil, most notably those inspired by wing cross sections from specific insect species has very little effect on the wake interaction, but oddly enough seems to have an impact on the lift generated. Comparing performance from these cross-sections to the performance of more conventional cross-sections showed considerable increases making them excellent candidates for future MAVs. Also the unconventional “limp wrist” motion that was discovered by doubling the frequency of the pitch over the plunge displayed favorable performance characteristics give an intelligent selection of the pivot point. Pivot points closer to the leading edge of the airfoil showed remarkable averaged thrust and lift coefficients and pivot points closer to the trailing edge of the airfoil showed very high values of lift, unfortunately also showed high values of drag as well. All conclusions seem to point to the fact that there is still much to be learned in this area of unsteady aeronautics as there seems to be hundreds of parameters and options to exercise.

ABSTRACT
The objective of this thesis was to determine the feasibility of using loop heat pipes to dissipate waste heat from power electronics to the skin of a fighter aircraft and examine the performance characteristics of a titanium-water loop heat pipe under stationary and elevated acceleration fields. In the past, it has been found that the boundary condition at the condenser can be a controlling factor in the overall performance of this type of thermal management scheme. Therefore, the heat transfer removed from the aircraft skin has been determined as a function of Ma∞ = 0.8 to 1.4, H = 0 to 22 km, and Tw = 105 to 135°C by modeling the wing as a flat plate at zero-incidence. In addition, the effects of the variable properties of air have been taken into account. Heat transfer due to thermal radiation has been neglected in this analysis due to the low skin temperatures and high airspeeds up to Ma∞ = 1.4. It was observed that flight speed and altitude have a significant effect on the heat transfer abilities from the skin to ambient, with heat rejection becoming more difficult with increasing Mach number or decreasing altitude.

An experiment has been developed to examine operating characteristics of a titanium-water loop heat pipe (LHP) under stationary and elevated acceleration fields. The LHP was mounted on a 2.44 m diameter centrifuge table on edge with heat applied to the evaporator via a mica heater and heat rejected using a high-temperature polyalphaolefin coolant loop. The LHP was tested under the following parametric ranges: Heat load at the evaporator: 100 ≤ Qin ≤ 600 W; heat load at the compensation chamber: 0 ≤ Qcc ≤ 50 W; radial acceleration: 0 ≤ ar ≤ 10 g. For stationary operation (az = 1.0 g, ar = 0 g), the LHP evaporative heat transfer coefficient decreased monotonically while the thermal resistance decreased to a minimum then increased. Flow reversal in the LHP was found for some cases, which was likely due to vapor bubble formation in the primary wick. Heat input to the compensation chamber was found to increase the evaporative heat transfer coefficient and decrease thermal resistance for Qin = 500 W. Operating the LHP in an elevated acceleration environment revealed dry-out conditions from Qin = 100 to 400 W and varying accelerations and the ability for the LHP to reprime after an acceleration event that induced dry-out.

ABSTRACT
Real-world scenarios are complex dynamic systems that are often overloaded with information. Human operators, constantly monitor and control these systems, assess the situation and often make decisions under time pressure. However, this supervisory control paradigm in a dual-task environment can be a very challenging task. Existing interface design methodologies have not delved deeply enough into defining information displays for complex, dynamic, time-critical, dual-task environments with capabilities for rapid task change awareness and task resumption while continuously maintaining situation awareness. This research focuses on designing user displays with techniques to support performance in
such dual-task environments. This research provides a means to realize an “at-a-glance” decision making environment.

ABSTRACT
The classic vehicle routing problem considers the distribution of goods to geographically scattered customers from a central depot using a homogeneous fleet of vehicles with finite capacity. Each customer has a known demand and can be visited by exactly one vehicle. Each vehicle services the assigned customers in such a way that all customers are fully supplied and the total service does not exceed the vehicle capacity. In the split delivery vehicle routing problem, a customer can be visited by more than one vehicle, i.e., a customer demand can be split between various vehicles. Allowing split deliveries has been proven to potentially reduce the operational costs of the fleet.

This research efficiently solves the split delivery vehicle routing problem using three new approaches. In the first approach, the problem is solved in two stages. During the first stage, an initial solution is found by means of a greedy approach that can produce high quality solutions comparable to those obtained with existing sophisticated approaches. The greedy approach is based on a novel concept called the route angle control measure that helps to produce spatially thin routes and avoids crossing routes. In the second stage, this constructive approach is extended to an iterative approach using adaptive memory concepts, and then a variable neighborhood descent process is added to improve the solution obtained. The second approach presents a new solution diversification scheme based on concentric rings centered at the depot that partitions the original problem. The resulting subproblems are then solved using the greedy approach with route angle control measures. Different ring settings produce varied partitions and thus different solutions to the original problem are obtained and improved via a variable neighborhood descent. The third approach is a learning procedure based on a set or population of solutions. Those solutions are used to find attractive attributes and construct new solutions within a tabu search framework. As the search progresses, the existing population evolve, better solutions are included on whereas bad solutions are removed from it. The initial set is constructed using the greedy approach with the route angle control measure whereas new solutions are created using an adaptation of the well known savings algorithm of Clarke and Wright (1964) and improved by means of an enhanced version of the variable neighborhood descent process. The proposed approaches are tested on benchmark instances and results are compared with existing implementations.

ABSTRACT
Previous research has suggested that the damping of specimens that have a hard ceramic coating applied on them is proportional to the thickness of the coating. This would indicate that the damping is a volume dependent material property. Since thickness variations are likely in an actual application it is essential that the role that coating thickness plays in the damping effectiveness is understood. For this research a series of tests were conducted using substrate beams of 90 mil Ti-6Al-4V, coated with 3 mils of an air plasma sprayed NiCrAlY bond coat followed by a Titania-Alumina ceramic blend coating applied via air plasma spray in one of three thicknesses (5 mil, 10 mil and 15 mil). Four specimens were coated at each thickness for a total of 12 specimens. The system loss factor and natural frequencies were measured for each specimen at each stage to determine the contributions of the bare beam, the bond coat and the ceramic coating. This information was used with the dimensions at each stage to determine the material properties (storage modulus, loss modulus and loss factor) for the bond coat and the ceramic. The material properties of a thickness-independent material must be the same for all thicknesses and differences in the results of different thickness specimens allow the ability to determine and quantify a thickness effect.

ABSTRACT
Trace additions of boron have been shown to decrease the as-cast grain size in alpha + beta and beta titanium alloys. Two metastable beta titanium alloys: Beta21S and Ti5553 with 0.1 wt% B and without boron additions were used in this investigation. Significant grain refinement of the as-cast microstructure and precipitation of TiB whiskers along the grain boundaries was observed with boron additions. Beta21S and Beta21S-0.1B alloys were annealed above the beta transition temperature for different times to investigate the effect of boron on grain size stability. The TiB precipitates were very effective in restricting the beta grain boundary mobility by Zener pinning. A model has been developed to predict the maximum grain size as a function of TiB size, orientation, and volume fraction. Good agreement was obtained between model predictions and experimental results.

All four alloys were solution treated and aged for different times at several temperatures below the beta transus to study the kinetics of alpha precipitation. Though the TiB phase did not provide any additional nucleation sites for alpha precipitation, the grain refinement obtained by boron additions resulted in accelerated aging.

An investigation of the thermomechanical processing behavior showed different deformation mechanisms above the beta transus temperature. The non-boron containing alloys showed a non-uniform and fine recrystallized necklace structure at grain boundaries whereas uniform intragranular recrystallization was observed in boron containing alloys. Micro-voids were observed at the ends of the TiB needles at high temperature, slow strain rates as a result of decohesion at the TiB / matrix interfaces. At low temperatures and faster strain rates microvoids were also formed due to fracture of TiB needles.

ABSTRACT
There is little argument that modern military systems are very complex, both in terms of the resources in time and money to develop them and the infrastructure that is required to produce trained operators. To properly execute human systems integration during the acquisition process, systems built to train operators must be developed that optimize training. Consequently, the training system community would benefit from simulation models that provide the ability to make accurate predictions of training processes, and allow the decision maker to specify an optimum combination of operator performance after training and the cost of that training. The goal of this research is the construction of a model of human learning using time to complete a task as a performance measure. While past research has explored the nature of functions to characterize human learning, this study will examine processes used to build a model that considers task performance as a function of training methods used to instruct a task, the nature of the task being taught, and the ability of the human to retain skill over a specified period of nonuse. An empirical study was performed to collect data from individuals completing tasks typically performed by sensor operators assigned to military unmanned aircraft systems. The tasks performed covered a range of activities that require varying combinations of human perceptual, cognitive and motor skills. The data was fitted to a set of models that were used to predict the performance outcome of a task similar in task type to those used to build the model. Results are reported and recommendations for future research are offered.

Abstract
Design of turbine engine components is constrained by both iteration time and prediction uncertainty. Use of accurate reduced-order models enables a thorough exploration of the design space that leads to high performance components. This work develops three reduced-order modeling approaches for turbomachinery design. The first develops a Probabilistic Gradient Kriging approach to efficiently model the uncertainty in predicted failure probabilities caused by small sample statistics. The second develops turbine engine airfoil modal response approximation based on eigensensitivity analysis, principal component analysis geometric reduction, and Taylor series response expansion. The third predicts mistuned rotor forced response using nominal and non-nominal mode approximation in a Craig-Bampton Component Mode Synthesis framework.

Abstract
Fretting wear is an accumulation of damage that occurs at component interfaces that are subjected to high contact stresses coupled with low amplitude oscillation. The key to fretting wear reduction in metallic contacts is the mitigation of galling at the interface, followed by the control of debris production and the rheology of active wear debris. Once the thin surface species of the metallic interfaces is dispersed, adhesion between the contacting nascent surfaces causes the inception of severe surface deformation and material transfer or removal. This is extremely apparent in the fretting wear of aerospace materials such as titanium alloy and nickel alloy contacts. However, the literature suggests that nickel alloy contacts perform very well in sliding and reciprocating wear contacts at elevated temperatures due to the formation of what is often called a ‘Glaze’ oxide layer. The current state of literature describes the composition of the glaze layer as NiO. The focus of this dissertation was to provide experimentation and analysis of temperature effects on the lubricious tribofilm formation that occurs in nickel contacts. This was accomplished by testing commercially pure nickel coatings and thick nickel oxide surfaces. The enhanced understanding of the fretting performance of nickel oxides aided in the development of nickel graphite based self-lubricating coatings. These coatings were then proved to reduce fretting wear damage within Ti6Al4V mated surfaces over a wide temperature range.

ABSTRACT
Recent work has proposed a dissipated energy theory of fatigue crack growth in layered materials under mixed-mode loading. An inherent assumption of this prior work is that a perfect crack exists along the interface joining the top and bottom layers. The current work extends the approach of previous studies to incorporate a grading of plastic properties between the two layers through parametric finite element modeling with ABAQUS. An elastic-plastic 2D model using 8-node biquadratic elements was used to map the plastic dissipation of a two layer specimen with a grading of plastic properties parallel to the crack face. This property gradient allows for a more realistic representation of the plastic dissipation accumulated during a steady state cracking configuration. As a result, more accurate fatigue crack growth rates in layered material systems can be predicted. It was found that incorporation of a graded layer increased the amount of plastic dissipation. While this graded layer effect cannot be ignored, plastic dissipation is still dominated by the mode of loading.

ABSTRACT
The research in this dissertation involves the study of several multi-echelon inventory systems with stochastic capacity and intermediate product demand. Specifically we analyze the behavior of the system which consists of several intermediate product demands. The analysis is primarily three fold i) developed update (relational) equations for all the multi-echelon inventory systems under several inventory allocation policies, ii) develop two simulation optimization approaches 1) OptQuest framework, and 2) IPA (Infinitesimal Perturbation Analysis) framework, used to minimize the total cost of the inventory systems that satisfy the desired customer service level, iii) obtain numerical results for all the multi-echelon inventory systems under several scenarios and instances, and perform an extensive analysis and implications of the results.

The research done in this dissertation differ from earlier works, since it considers a complex (combination of serial and assembly systems) multi-period multi-echelon inventory system with several sources of demand (specifically intermediate product demands). We obtain the optimal base-stock levels for each node in the system that satisfies the required customer service level. A SIO (Simulation based Inventory Optimization) approach is used to obtain the optimal base-stock level for the system under several inventory allocation policies. We consider a system which is closer to the actual world and can be used to solve contemporary issues like, 1) manufacturing firm that produces finished products as well as spare parts, 2) manufacturer – warehouse – distribution center – retail outlets etc. I am not aware of any work that studies the impact of inventory allocation polices for multi-period in a multiechelon inventory system, and obtains optimal base stock level for each node using an IPA framework. Moreover the optimal base-stock level for each node is obtained under realistic conditions like
stochastic demand, stochastic capacity, and lead time.

Abstract
Recent studies suggest that spectrum congestion is mainly due to the inefficient use of spectrum rather than its unavailability. Dynamic Spectrum Access (DSA) and Cognitive Radio (CR) are two terminologies used in the context of improved spectrum efficiency and usage. The advent of CR has created a paradigm shift in wireless communications and instigated a change in Federal Communication Commission (FCC) policy towards spectrum regulations. Spectrum overlay and underlay techniques fall within the hierarchical DSA model and enable primary and secondary users to coexist while improving overall spectrum efficiency. As addressed here, spectrum overlay exploits unused spectral regions while spectrum underlay exploits underused spectral regions. Similar to Ultra Wide Band (UWB) transmissions, underlay approaches utilize much more spectrum than overlay approaches and operate below the noise floor of primary users.

Spectrally modulated, spectrally encoded (SMSE) signals, to include Orthogonal Frequency Domain Multiplexing (OFDM) and Multi-Carrier Code Division Multiple Access (MC-CDMA), are candidate CR waveforms. The SMSE structure supports and is well-suited for CR-based Software Defined Radio (SDR) applications. This dissertation provides a novel, soft decision CR framework that extends the previously developed SMSE framework to achieve synergistic benefits of overlay and underlay techniques. The extended framework provides considerable flexibility to design overlay, underlay and hybrid overlay/underlay waveforms that are scenario dependent. Overlay/underlay framework flexibility is demonstrated by applying it to a family of SMSE signals, including OFDM, MC-CDMA, Carrier Interferometry MC-CDMA (CI/MC-CDMA) and Transform Domain Communication System (TDCS).

Abstract

The work performed investigates the system design and optimization of an undersea vehicle. The system design is driven by the available components, the missions the vehicle is required to perform, and the performance the system configuration yields. The system design consists of three design modules: path planning, component selection and sizing, and structural analysis. The path planning module uses a novel application of the Particle Swarm Optimization algorithm named Path Planning by Additive Freedom. Additionally, the unknown aspects of the mission space through which the path propagates are dealt with using an uncertainty quantification method known as Evidence Theory. Component selection and sizing are performed using the naval design tool SNARC. This program uses a branch and bound technique called the A* algorithm to choose the components that should be used in the system and what size they should be according to the mission profiles provided by the path. The structural analysis is performed using the ABAQUS finite element program to calculate the structural reliability of the system. This module uses the structure sizing data, as well as the hydrodynamic and hydrostatic forces from the mission profile, to calculate the system's reliability with respect to a buckling failure, the most common structural failure in undersea vehicles.

Abstract

Optical tomosynthetic imaging of 3-D objects from disparate 2-D images has been limited in the past by a lack of algorithmic enforcement of physical constraints, in particular within-scene obscuration and object self-occlusion. This paper presents a stochastic observation model of a tomosynthetic collection that explicitly includes an obscuration operator that is unknown by the sensor. The expectation-maximization algorithm is used to iteratively estimate the obscuration operator and to reconstruct the 3-D volume of interest. Explicit inclusion of obscuration effects greatly enhances the spatial and spectral accuracy of 3-D results without use of costly post-processing techniques. Performance metrics are introduced and the resultant receiver operating characteristics are presented.
