Thermal Modeling And Laser Beam Shaping For Microvias Drilling In High Density Packaging, Chong Zhang
Electronic Theses and Dissertations
Laser drilling of microvias for organic packaging applications is studied in present research. Thermal model is essential to understand the laser-materials interactions and to control laser drilling of blind micro holes through polymeric dielectrics in multilayer electronic substrates. In order to understand the profile of the drilling front irradiated with different laser beam profiles, a transient heat conduction model including vaporization parameters is constructed. The absorption length in the dielectric is also considered in this model. Therefore, the volumetric heating source criteria are applied in the model and the equations are solved analytically. The microvia drilling speed, temperature distribution in …

Evaluating Tactical Combat Casualty Care Training Treatments Effects On Combat Medic Trainees In Light Of Select Human Descripti, Teresita Sotomayor
Electronic Theses and Dissertations
The use of military forces in urban operations has increased considerably over the past years. As illustrated by the current conflict in Iraq, the Army finds itself fighting its toughest battles in urban areas facing unconventional forces. Soldiers face many threats in hostile fire environments, whether conducting large-scale mechanized warfare, low-intensity conflicts, or operations other than war. Through 1970, there has been no demonstrable reduction in battlefield mortality rate as a percentage of all casualties since data was kept since before the Civil War. For that period of time, nearly all the reduction in overall mortality rate occurred through reduced …
Phase And Amplitude Modulated Ofdm For Dispersion Managed Wdm Systems, Andreas Eisele
Phase And Amplitude Modulated Ofdm For Dispersion Managed Wdm Systems, Andreas Eisele
Electronic Theses and Dissertations
Amplitude and phase modulated optical OFDM (Orthogonal Frequency Division Multiplexing) are analyzed in a 50GBit/s single channel and 40GBit/s 5 channel 512 subcarrier non-ideal dispersion-compensated fiber optic communication systems. PM-OFDM is investigated as an alternative to AM-OFDM to alleviate the problem associated with amplitude-modulated signals in a nonlinear medium. The inherent dispersion compensation capability in OFDM (using a cyclic prefix) allows transmission over a link whose dispersion map is not exactly known. OFDM also mitigates the effects of dispersion slope in wavelength-division multiplexed (WDM) systems. Moreover, the overall dispersion throughout the transmission link may vary due to environmental effects and …
High Power Mode-Locked Semiconductor Lasers And Their Applications, Shinwook Lee
High Power Mode-Locked Semiconductor Lasers And Their Applications, Shinwook Lee
Electronic Theses and Dissertations
In this dissertation, a novel semiconductor mode-locked oscillator which is an extension of eXtreme Chirped Pulse Amplification (XCPA) is investigated. An eXtreme Chirped Pulse Oscillator (XCPO) implemented with a Theta cavity also based on a semiconductor gain is presented for generating more than 30ns frequency-swept pulses with more than 100pJ of pulse energy and 3.6ps compressed pulses directly from the oscillator. The XCPO shows the two distinct characteristics which are the scalability of the output energy and the mode-locked spectrum with respect to repetition rate. The laser cavity design allows for low repetition rate operation < 100MHz. The cavity significantly reduces nonlinear carrier dynamics, integrated self phase modulation (SPM), and fast gain recovery in a Semiconductor optical Amplifier (SOA). Secondly, a functional device, called a Grating Coupled Surface Emitting Laser (GCSEL) is investigated. For the first time, passive and hybrid mode-locking of a GCSEL is achieved by using saturable absorption in the passive section of GCSEL. To verify the present limitation of the GCSEL for passive and hybrid mode-locking, a dispersion matched cavity is explored. In addition, a Grating Coupled surface emitting Semiconductor Optical Amplifier (GCSOA) is also investigated to achieve high energy pulse. An energy extraction experiment for GCSOA using stretched pulses generated from the colliding pulse semiconductor mode-locked laser via a chirped fiber bragg grating, which exploits the XCPA advantages is also demonstrated. Finally, passive optical cavity amplification using an enhancement cavity is presented. In order to achieve the interferometric stability, the Hänsch-Couillaud Method is employed to stabilize the passive optical cavity. The astigmatism-free optical cavity employing an acousto-optic modulator (AOM) is designed and demonstrated. In the passive optical cavity, a 7.2 of amplification factor is achieved with a 50 KHz dumping rate.
Moderators Of Trust And Reliance Across Multiple Decision Aids, Jennifer Ross
Moderators Of Trust And Reliance Across Multiple Decision Aids, Jennifer Ross
Electronic Theses and Dissertations
The present work examines whether user's trust of and reliance on automation, were affected by the manipulations of user's perception of the responding agent. These manipulations included agent reliability, agent type, and failure salience. Previous work has shown that automation is not uniformly beneficial; problems can occur because operators fail to rely upon automation appropriately, by either misuse (overreliance) or disuse (underreliance). This is because operators often face difficulties in understanding how to combine their judgment with that of an automated aid. This difficulty is especially prevalent in complex tasks in which users rely heavily on automation to reduce their …
Many Telling Moments:The Essence Of Fragmented Image Culture, Bonnie Ebner
Many Telling Moments:The Essence Of Fragmented Image Culture, Bonnie Ebner
Electronic Theses and Dissertations
My purpose in entering the UCF MFA program was to further explore and develop my passion for photography. During my time in the program, I developed my methodology--from having the traditional photography paradigm ingrained in my mind (and wanting to fit into it) to accepting and valuing my own unique process. I construct installations using diverse imagery and non-traditional presentation. In my installations, one may witness a reflection of the contemporary pace of image perception--fragmented, complex, abundant, and disordered. Together, images and their arrangements are used to create a unified piece that satisfies a new system within apparent disorder. The …

Wet Weather Impact On Trihalomethane Formation Potential In Tributaries To Drinking Water Reservoirs, Eid A. Alkhatib, R. Peters
Chemistry & Physics Faculty Publications
During rain storm events, land surface runoff and resuspension of bottom sediments cause an increase in Trihalomethane (THM) precursors in rivers. These precursors, when chlorinated at water treatment facilities will lead to the formation of THMs and hence impact drinking water resources. In order to evaluate the wet weather impact on the potential formation of THMs, river samples were collected before, during and after three rain storms ranging from 15.2 to 24.9 mm precipitation. The samples were tested for THM formation potential and other indicators including UV254 absorbance, turbidity and volatile suspended solid (VSS). Average levels of THMs increased from …

Formative Versus Reflective Measurement: Comment On Marakas, Johnson, And Clay (2007), Andrew M. Hardin, Jerry Cha-Jan Chang, Mark A. Fuller
Management, Entrepreneurship and Technology Faculty Research
In a recent issue of the Journal of the Association for Information Systems, Marakas, Johnson, and Clay (2007) presented an interesting and important discussion on formative versus reflective measurement, specifically related to the measurement of the computer self-efficacy (CSE) construct. However, we believe their recommendation to measure CSE constructs using formative indicators merits additional dialogue before being adopted by researchers. In the current study we discuss why the substantive theory underlying the CSE construct suggests that it is best measured using reflective indicators. We then provide empirical evidence demonstrating how the misspecification of existing CSE measures as formative can result …

Realizing Degree Sequences With Graphs Having Nowhere-Zero 3-Flows, Rong Luo, Rui Xu, Wenan Zang, Cun-Quan Zhang
Faculty & Staff Scholarship
The following open problem was proposed by Archdeacon: Characterize all graphical sequences π such that some realization of π admits a nowhere-zero 3-flow. The purpose of this paper is to resolve this problem and present a complete characterization: A graphical sequence π = (d1, d2, ., dn) with minimum degree at least two has a realization that admits a nowhere-zero 3-flow if and only if π ≠ (34, 2), (k, 3k), (k2, 3k―1), where k is an odd integer.

Kierkegaard And/Or Catholicism: A Matter Of Conjunctions, Center For Catholic Studies, Seton Hall University
Center for Catholic Studies Faculty Seminars and Core Curriculum Seminars
It is often said (accurately) that one of the distinguishing marks of a Catholic understanding of life is its both-and approach in contrast to the either-or approach more characteristic of a Protestant sensibility. For example, Catholics tend to live with and argue for both scripture and tradition, faith and works. The Danish Lutheran Søren Kierkegaard is often cited as a paradigm of Protestant either-or thinking. In this seminar we will explore what we might learn not only about Catholicism and Kierkegaard, but even more about Christianity, human life, and the logic of conjunction.
