Human Reliability Analysis In The Performance Of Advanced Cardiac Life Support Tasks, Lucia Veronica Rosas

Theses and Dissertations - UTB/UTPA

Error reduction in the performance of medical emergency situations is an area of great concern in today's society. This is specially the case when the situation involves a cardiac arrhythmia. These situations are generally categorized as Advanced Cardiac Life Support (ACLS) events. The American Heart Association provides the proper procedures that practitioners of ACLS should follow to provide care to patients presenting heart arrhythmia problems. These situations occur inside and outside the hospital, outside the hospital being the most critical ones considering the limitation of equipment and availability of qualified care. Errors made by the practitioners of ACLS in this …

Exploring The Managerial Intuition And Knowledge Of Managers In Mexico's Maquiladora Industry, Jose Castillo

Theses and Dissertations - UTB/UTPA

Decision-making has been a subject of interest for management scholars since the scientific management era (Wren, 1994). Brockmann and Simmonds (1997) and Guinipero, Dawley and Anthony (1999) studied the link between managerial decision-making and tacit knowledge in the effort to identify important cognitive elements in the day-to-day decision-making processes of firm managers. Despite their bold and innovative aims, however, Brockmann et al. (1997) and Guinipero et al. (1999) were weakened by their fundamental assumption that tacit knowledge is synonymous to intuition, and by inconsistencies in their research goals and methods. This dissertation addresses these shortcomings.

Analysis Of Lifting Performance Capacity Through An Integrated Learning Curve Model, Jose Roel Flores

Theses and Dissertations - UTB/UTPA

Physical fitness specific to job demands is necessary for jobs that require moderate or heavy effort. Fitness training is needed not just when a new job is learned but also when an individual has been away from the job for a few weeks and returns to perform the task. The basic problem is to have a good understanding of the dynamics of performance capacities to establish training and retraining regimes to prevent overexertion. To obtain this, a better understanding of the behavior of performance capacity over time is necessary. A performance capacity training regimen was designed for tasks that required …

Expert System Development For Hard Disk Drive Failure Analysis, Fernando Rodriguez Rosas

Theses and Dissertations - UTB/UTPA

The Computer's Hard Disk Drive is a complex high technology device, diagnosis of a failure is difficult even using sophisticated test equipments. These Drives are expensive and returning a new one when it fails within the warranty period is not an option. The failed drive must be tested and repaired. In the repair process the analysis and diagnosis of the failures is a key point in the process where decisions regarding the repair process that the failed Drive will follow. Therefore, there is a requirement to perform an effective analysis and provide an accurate diagnosis. The standard system utilized for …

Analysis Of Performance Capacity Of Hand Grip Through An Integrated Learning Curve Model, Miguel Torres

Theses and Dissertations - UTB/UTPA

There are few activities or work task in the manufacturing industry that does not involve grip strength. That is why it is in the best interest of the manufacturing industry to have an understanding of the optimum grip strength gain capacity over time that would lead to better performance, accuracy and most of all prevent hand grip related injuries. For that reason, this thesis was concentrated in discovering a possible basic working model for estimating grip strength over time for a specific grip strength activity. The first step was to observe the trend characteristics of the strength gain data over …

Near-Field Calculations For A Rigid Spheroid With An Arbitrary Incident Acoustic Field, John P. Barton, Nicholas L. Wolff, Haifeng Zhang, Constantine Tarawneh

Mechanical Engineering Faculty Publications

A general spheroidal coordinate separation-of-variables solution is developed for the determination of the acoustic pressure distribution near the surface of a rigid spheroid for a monofrequency incident acoustic field of arbitrary character. Calculations are presented, for both the prolate and oblate geometries, demonstrating the effects of incident field orientation and character (plane-wave, spherical wave, cylindrical wave, and focused beam) on the resultant acoustic pressure distribution.

Normal And Lateral Casimir Forces Between Deformed Plates, Thorsten Emig, Andreas Hanke, Ramin Golestanian, Mehran Kardar

Physics & Astronomy Faculty Publications

The general path-integral formulation was set up for Casimir energy of the electromagnetic gauge field. By separating into transversal electric and magnetic modes, the problem was reduced to two decoupled problems for scalar fields which differ only in their boundary conditions. In each case, the Casimir energy was calculated for general plate deformations perturbatively. Results on both the normal and the lateral force between sinusoidally corrugated plates were outlined.

Avid: A Comprehensive School Reform Model For Texas, Karen M. Watt, Darlene Yanez, Griselda Cossio

Organization and School Leadership Faculty Publications

The implementation of a recent comprehensive school reform effort in the state of Texas bas been examined in this article. The effort, Advancement Via Individual Determination (AVID), was studied in-depth over the two-year implementation period through school visits, observations, stakeholder interviews, and student performance data analysis. Main findings revealed that through proper implementation (strong instructional leadership, using AVID strategies school-wide, and staff development), underachieving, economically disadvantaged, ethnic minority students can succeed in a rigorous curriculum. AVID is a catalyst for school-wide reform; AVID addresses and influences school policies that can be barriers to student success; AVID is a pathway to …

Spontaneous Magnetization Generated By Spin, Pulsating, And Planar Combustion Synthesis, Karen S. Martirosyan, J. R. Claycomb, G. Gogoshin, R. A. Yarbrough, J. H. Miller Jr., D. Luss

Physics & Astronomy Faculty Publications

The motion of the high temperature front during combustion synthesis of ferrite materials generates residual magnetization in cylindrical product samples. The combustion wave created a current density of up to 10 A/cm2, which influenced the magnetization distribution. The measured peak magnetic field intensity was up to 8 mT. Qualitatively different magnetic field maps were generated in ferrite samples synthesized by different combustion modes. The average magnetization vector generated by either planar or pulsating combustion was oriented at a smaller angle with respect to the pellet axis ~f<45°! than those generated by spin combustion ~60°

Mode-Cleaning And Injection Optics Of The Gravitational-Wave Detector Geo600, S. Goßler, M. M. Casey, A. Grant, H. Grote, Volker Quetschke

Physics & Astronomy Faculty Publications

The British–German interferometric gravitational-wave detector GEO600 uses two high-finesse triangular ring cavities of 8 m optical pathlength each, as an optical mode-cleaning system. The modecleaner system is housed in an ultrahigh-vacuum environment to avoid contamination of the optics and to minimize both the influence of refractive index variations of the air and acoustic coupling to the optics. To isolate the cavities from seismic noise, all optical components are suspended as double pendulums. These pendulums are damped at their resonance frequencies at the upper pendulum stage with magnet-coil actuators. A suspended reaction mass supports three coils matching magnets bonded onto the …

Category Of Nonlinear Evolution Equations, Algebraic Structure, And R-Matrix, Zhijun Qiao, Cewen Cao, Walter Strampp

School of Mathematical & Statistical Sciences Faculty Publications

In this paper we deal with the category of nonlinear evolution equations ~NLEEs! associated with the spectral problem and provide an approach for constructing their algebraic structure and r-matrix. First we introduce the category of NLEEs, which is composed of various positive order and negative order hierarchies of NLEEs both integrable and nonintegrable. The whole category of NLEEs possesses a generalized Lax representation. Next, we present two different Lie algebraic structures of the Lax operator: one of them is universal in the category, i.e., independent of the hierarchy, while the other one is nonuniversal in the hierarchy, i.e., dependent on …
