Paul\u27s Concept of Christ as the Wisdom of God

Our purpose, then, will be an objective comparison of the functions of Paul\u27s Sophia with the personal Chokmah. The logos of John will frequently enter in by way of comparison. The close relationship between the three will be evident throughout

New Testament Preaching- An Analysis of its Character and Purpose on the Basis of Word Studies of Αγγελλω and its Compounds and Κηρυσσω

Since this study is based merely based on two of the verbs used in the New Testament to describe Christian preaching, it does not afford a basis for comparison in regard to all preaching. We shall be describing and comparing Apostolic preaching and present-day preaching only in a restricted area

Imaging with two-axis micromirrors

We demonstrate a means of creating a digital image by using a two axis tilt micromirror to scan a scene. For each different orientation we extract a single grayscale value from the mirror and combine them to form a single composite image. This allows one to choose the distribution of the samples, and so in principle a variable resolution image could be created. We demonstrate this ability to control resolution by constructing a voltage table that compensates for the non-linear response of the mirrors to the applied voltage.Comment: 8 pages, 5 figures, preprin

Research on solar pumped liquid lasers

A solar pumped liquid laser that can be scaled up to high power (10Mw CW) for space applications was developed. Liquid lasers have the inherent advantage over gases in that they provide much higher lasant densities and thus high power densities. Liquids also have inherent advantages over solids in that they have much higher damage thresholds and are much cheaper to produce for large scale applications. Among the liquid laser media that are potential candidates for solar pumping, the POC13:Nd(3+):ZrC14 liquid was chosen for its high intrinsic efficiency as well as its relatively good stability against decomposition due to protic contamination. The development and testing of the laser liquid and the development of a large solar concentrator to pump the laser was emphasized. The procedure to manufacture the laser liquid must include diagnostic tests of the solvent purity (from protic contamination) at various stages in the production process

CBCT Image Quality Assessment Testing Clinically Relevant Volume Orientation and Position

Introduction and Objectives: Some physical measures of CBCT image quality correlate well with diagnostic image quality. Traditionally, these measures have been assessed in the center in a standard orientation. The purpose of this study was to test whether measures of image quality vary as a function of test tool location, orientation and dose. The second purpose was to determine if there was an association between objective and subjective image quality. Methods: CBCT objective image quality was assessed with one standard and three modified phantoms using five fields of view. The test tool was located at the center of the phantom (standard), at the periphery (Mod1), angled and at the center (Mod2), or angled plane and at the periphery (Mod3). Phantoms were imaged with a Carestream CS 9300 CBCT scanner (Carestream, Rochester, NY), using SDSR (180-250µm voxel/90kVp/64mAs) and LDLR (400µm voxel/85kVp/14.5mAs) for each field-of-view. Contrast-to-noise ratio (CNR) and 10% modulation transfer function (MTF) were assessed in three repeated volumes. Data were analyzed using ANOVA and Tukey’s HSD. Subjective image quality was assessed with a pairwise comparison of anatomical landmarks corresponding to the test tool locations and orientations. Data were analyzed using logistic regression. Results: CNR differed by phantom (p<0.0001) and dose (p<0.0001) for the 8x8 and 17x11 cm FOVs. Mod3 displayed significantly greater CNR than other phantoms. Low dose protocol provided higher CNR. MTF differed only by dose (p<0.0001) for the 8x8, 17x6, and 17x11 cm FOVs. SDSR provided higher MTF. Dose protocol was statistically significant for subjective image quality. Observers preferred images with higher MTF rather than higher CNR. Mod3 was negatively associated with observer preference. The 17x6cm FOV was positively associated with observer preference. Conclusions: CNR improved for a peripherally positioned angled test tool (Mod3). Reduced kVp and larger voxels appear to counteract the effect of reduced mAs producing improved CNR at LDLR. Thus, image quality parameters are different at the center of a CBCT volume when compared to the periphery, depend on the orientation of the object, and vary as a function of kVp and voxel size. Observers preferred images with a higher MTF rather than higher CNR.Master of Scienc

Optical Propagation Methods for System-Level Modeling of Optical MEM Systems

In this thesis, we determine and implement an optical propagation technique suitable for system-level simulation of optical micro-systems. The Rayleigh-Sommerfeld formulation is selected as the optical propagation modeling technique because it satisfies the requirements of a system-level CAD tool and supports accurate modeling at propagation distances on the order of the wavelength of light. We present an efficient solution to the Rayleigh-Sommerfeld formulation using the angular spectrum technique which uses the fast Fourier transform to decompose the complex optical wavefront into plane waves propagating from the aperture to the observation plane. This technique reduces the computational order of solving the Rayleigh-Sommerfeld formulation from a brute force direct integration technique of O(N4) to a computational order of O(N2logN).For use in a design environment, we present an error analysis of our technique. Errors are caused by the discrete sampling of the optical wavefront over a finite range to approximate the infinite continuous Fourier transform. Methods for reducing both aliasing and truncation errors are presented, along with techniques to estimate the remaining errors of the angular spectrum technique. We perform a rigorous error estimate on several common optical wavefronts and provide techniques to perform an error analysis on a general wavefront. The utility of this method is shown by implementing the work into a mixed-signal, multi-domain CAD tool, in which we perform system-level simulations and analyses of several optical MEM systems
