Survey Of Aviation Maintenance Technical Manuals, Phase 3 Report: Final Report And Recommendations, Alex Chaparro, Loren S. Groff

Publications

This report contains the results from the final phase of a three-phase research effort. Phase 1 of this research effort surveyed the procedures used by five aircraft manufacturers to develop maintenance documentation. Several potential human factors issues were identified in the processes used by these manufacturers to develop their maintenance manuals. The issues included the reactive rather than proactive use of user evaluations, the limited use of user input and procedure validation, no systematic attempts to track errors, and the lack of standards for measuring document quality. In Phase 2, a written survey was used to solicit information about user …

Cascading Visions, Noel Palmenez

Theses and Dissertations - UTB/UTPA

I view my work as a look into dreams, thoughts, ideas. My themes are universal, but their source derives from my specific surroundings, the Rio Grande Valley. They come out from the rows in the fields where we grow our foods, in the skies, and from the sun that warms our blood. Themes come from what I see as well as what I imagine, living and not. I consider myself a farmer, but now I harvest ideas and concepts, and have my paintings and drawings to show for my labor. I believe one must contribute to the land before one …

The Use Of Psychological State Terms By Late Talkers At Age 3, Eliza Carlson Lee, Leslie Rescorla

Psychology Faculty Research and Scholarship

The use of psychological state words during mother-child play sessions at age 3 was examined in 31 children diagnosed with delayed expressive language at 24-31 months and 21 age-matched typically developing comparison children. Children and mothers in the late talker group made more references to physiological states and fewer references to cognitive states than the children and mothers in the typically developing comparison group. The children's use of cognitive terms correlated significantly with measures of language ability, including mean length of utterance, Index of Productive Syntax score, and use of propositional complements, as well as with their mothers' use of …

Automation Of The Superpave Mix Design Process For The West Virginia Division Of Highways, Martin Felix Padula

Graduate Theses, Dissertations, and Problem Reports (ETD)

During the fifty years between 1940 and 1990, the nation's bituminous roadways were predominantly designed using either the Marshall or Hveem method. The Superior Performing Asphalt Pavements (Superpave)(TM) method was later developed to address the issues of increased traffic volumes and heavier loads on the nation's roadways. This new mix design process relies on volumetric calculations and graphs, which are cumbersome to perform by hand. There is no current public domain Superpave software package available which is independent of any commercial laboratory product and available to an asphalt mix designer. A component of this research project consisted of creating a …

Early Component-Based Reliability Assessment Using Uml Based Software Models, William Black Smith V

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the last decade, software has grown in complexity and size, while development timelines have diminished. As a result, component-based software engineering is becoming routine. Component-based software reliability assessment combines the architecture of the system with the reliability of the components to obtain the system reliability. This allows developers to produce a reliable system and testers to focus on the vulnerable areas.;This thesis discusses a tool developed to implement the methodology previously created for early reliability assessment of component-based systems. The tool, Early Component-based Reliability Assessment (ECRA), uses Rational Rose Unified Modeling Language (UML) diagrams to predict the reliability of …

Harvested Log Damage And Value Loss Associated With Two Ground-Based Harvesting Systems In Central Appalachia, Michael R. Vanderberg

Graduate Theses, Dissertations, and Problem Reports (ETD)

Damage is often seen as an important consideration when conducting partial harvests in hardwood stands, as excessive damage to residual trees will significantly reduce the potential value of the residual stand. Damage to harvested logs, especially hardwood saw and veneer logs can be an even more important concern relative to value loss associated with log degrade. The log damage and value loss were examined by harvesting system, felling function, species, and damage type in central Appalachia. Observations were made of all grade logs during the felling, skidding, decking/sorting, and loading functions of the harvesting operations. Saw logs or veneer logs …

Source Localization Of Meg Sleep Spindles And The Relation To Sources Of Alpha Band Rhythms, Ilonka Manshanden, Jan C. De Munck, Norman R. Simon, Fernando H. Lopes Da Silva

Norman R. Simon Papers

Objective: First, to determine the distribution of the estimated sources of sleep spindles, and alpha and mu rhythms based on whole-head magnetoencephalogram (MEG) recordings; second, to scrutinize the physiological relevance of the dipole fit algorithm in localizing on-going normal rhythmic activities.

Methods: One hundred and fifty-one channels were used to record spontaneous MEG activity during wakefulness and superficial sleep in 4 normal subjects. The equivalent dipolar sources were estimated by a new “dipole fit algorithm” and projected on the corresponding magnetic resonance images.

Results: Equivalent dipoles of MEG spindles were distributed over the centro-parietal region. Those of alpha …

Electronic-Structure Modifications Induced By Surface Segregation In La0.65Pb0.35Mno3 Thin Films, C.N. Borca, B. Xu, T. Komesu, H.-K. Jeong, M.T. Liu, Sy_Hwang Liou, Shane Stadler, Y. Idzerda, Peter A. Dowben

Peter Dowben Publications

Using spin-polarized inverse photoemission and X-ray absorption spectroscopy techniques, we show that the electronic structure of La_0.65Pb_0.35MnO₃ thin films depends on the composition at the surface. With a gentle annealing procedure, the surface provides a maximum of 80% spin asymmetry at 0.5 eV above the Fermi level in spite of extensive Pb segregation. A heavily annealed (restructured) surface exhibits a reduced surface "ordering" temperature of 240 K (compared to the approximately 335 K bulk value) as well as a reduced spin asymmetry value of 40% at 0.5 eV above Fermi energy.

Virtual Electro-Photographic Printer Model, Sunadi Gunawan

Theses

A halftone image in the computer is a bitmap matrix that contains either 0 or 1 , where 0 means the printer will not deposit any toner onto a paper and 1 means the printer will deposit some amount of toner onto a paper. The amount of toner that is put by the printer onto a paper for a given input signal pattern is characterized. The hypothesis was that the distribution of toner mass on the paper for a given input matrix pattern can be modeled with a toner point spread function, a toner transfer efficiency function, and a noise …

Resonance Detection And Acoustic Behaviour In Polymer Intake Manifolds, Amrith Ramanan

Masters Theses

The Automotive Industry, over the last few years, has been placing major emphasis on the use of lightweight components in engines as well as other structural components. The material for these lightweight components are being chosen in such a way that they require minimal secondary operations to place the components in service. One area that has developed is the use of Polymer (Plastic) Intake Manifolds for Internal Combustion engines. Plastics meet all the criteria for quality low cost production with a minimum weight component. Plastic intake manifolds, however, have been found to be excessively noisy in operation. This noise can …

Aerodynamic Drag Reduction Of A Racing Motorcycle Through Vortex Generation, Gerald M. Angle Ii

Graduate Theses, Dissertations, and Problem Reports (ETD)

The aerodynamic drag of a racing-class motorcycle can be accomplished through either an overall redesign of the surfaces or through some type of flow control mechanism. Due to limitations on the size of the exterior shape the flow control techniques are more practical. Small metal vanes, known as vortex generators were used in this research to mix higher energy freestream air with the lower energy boundary layer, delaying boundary layer growth and separation. In testing performed in the West Virginia University Closed Loop Wind Tunnel a maximum reduction of 118 drag counts (10.1%) was measured. Due to an abnormally high …

Gasmak2 Model For Longwall Gob Gas Emission, Qinghua Jin

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis discusses the development and improvement of an empirical model---GASMAK2, that describes methane control requirements for the longwalling coal in gassy areas. This is not a theoretical model; it uses an empirically determined gas emission rate as an input. The computer program divides Longwall panels into segments, keeps track of the face advance and generates emission rates and volumes for both the entire panel and for individual zones within the panel. This model is Windows-based, uses the full capabilities of the Windows environment to provide a user-friendly program, and can aid in the determination of the number, size and …

Effects Of Response-Independent Stimulus Delivery And Functional Communication Training, Shannon S. Haag

Graduate Theses, Dissertations, and Problem Reports (ETD)

Two individuals with developmental delays with a history of problem behavior participated in this study. Its purpose was to examine the efficacy of combining two treatments demonstrated to reduce problem behavior: response-independent stimulus delivery and differential reinforcement of an alternative behavior. This study examined whether the response-independent delivery of an alternative preferred stimulus and differential reinforcement of manding resulted in increases in manding and suppression of problem behavior prior to and during the fading of the schedule of response-independent stimulus delivery. The study also examined the necessity of extinction to obtain suppression of problem behavior. The response-independent delivery of an …

Relationships Among Spirituality, Cognitive Processing, And Personal Control, Karri Bonner

Graduate Theses, Dissertations, and Problem Reports (ETD)

The current study was a cross-sectional investigation of how spirituality as a positive life theme might be related to a unique style of cognitive processing. Of secondary interest were the relationships among spirituality and other personal control variables. Using memory recall and recognition tasks, the current study sought to determine whether or not participants would attend more to positive, negative, neutral, or religious words. The results of the current study indicate that (1) older adults are more spiritual than younger adults, (2) higher spirituality is related to higher levels of optimism, (3) spirituality is related to an external locus of …

Effects Of Maternal Sleep Deprivation On Maternal Sensitivity And Contingent Responsiveness, Cheryl Wiedman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Research has revealed that sleep deprivation deleteriously affects several aspects of adults' behavior, such as mood, cognition, and motor performance. One population that is subject to sleep deprivation and the accompanying consequences are parents of young infants. The present study explored how sleep deprivation, resulting from infant night awakening, affects the face-to-face interaction between mothers and their 3- to 4-month-old infants. Contrary to the proposed hypotheses the groups did not differ in sensitivity or contingent responsiveness. However, regression analyses revealed that depression and sleep deprivation together significantly predicted contingent responsiveness during the interaction. Mothers who were more depressed and sleep …

Mansoura Medical Journal

Objective : To evaluate the early and midterm outcome in patients with coronary artery disease (CAD) and severe left ventricular (LV) dysfunc­tion, as defined by ejection fraction (LV EF) less than 35%, after coronary artery bypass grafting (CABG). Patients and methods : From April 1999 to June 2002, ninety seven pa­tients with CAD and EF < 35% had isolated CABG surgery. Preoperative-ly, patients were evaluated by history, physical examination, 12-leads ECG, echocardiographic study, and cardiac cathetenzation. In elective cases, via­bility studies were performed. All pa­tients had on pump CABG surgery. Patients were managed in the cardiac surgical ICU. After discharge, patients were followed up regularly in the car- diology out-patients clinic. Results: There were 76 males and 21 females. History of prior myocar-dial infarction was present in 46%. The main presenting symptoms were angina pectoris, heart failure, cardio-genie shock and pulmonary edema. Preoperatively, 59% of the patients were in New Your Heart Association Classification (NYHA) class III or IV. Coronary angiography revealed left main or triple vessel disease in 82%. More than half of the patients (54%) had moderately to severely dilated LV. The LV EF was: 30 - 35% in 26; 25 - 30% in 54; and 20 - 25% in 17 patients. All patients had LV wall mo­tion abnormalities which were found in more than 2 segments. Intra-aortic balloon pump was used in 36 pa­tients. . The average number of coro-

Travel Epidemiology. Who Perspective, Hussein A. Gezairy

Saudi Medical Journal

International travel is undertaken by large, and ever increasing numbers of people for professional, social, recreational and humanitarian purposes, and this upward trend looks set to continue. Travelers are exposed to a variety of health risks of the unfamiliar environment of the visited area. The risk of exposure is determined by destination, duration of the visit, purpose of the visit, behavior of the traveler and underlying physical and biological status of the traveler. However, most risks can be minimized by suitable precautions taken before, during and after travel. Travelers can themselves, also, easily introduce any infectious agents they may harbor …

Traumatic Fat Embolism Syndrome, Tarig S. Al-Khuwaitir, Abdurahman M. Al-Moghairi, Suphia M. Sherbeeni, Hamed M. Subh

Saudi Medical Journal

Traumatic fat embolism syndrome occurs most often following fractures of long bones sustained in road traffic accidents and is a common cause of medical consultation from the orthopedic surgery department. The sub-clinical presentation is subtle and expresses itself by the presence of hypoxemia, while the full clinical syndrome compromises respiratory insufficiency, an altered consciousness and a characteristic petechial rash. Recognition is simple once the patient is viewed in the context of his or her clinical setting. Diagnosis is aided further by the presence of hematological and biochemical abnormalities including anemia, thrombocytopenia, an elevated erythrocyte sedimentation rate and fat macroglobulinemia. Imaging …
