Protecting Soldiers From Friendly Fire: The Consent Requirement For Using Investigational Drugs And Vaccines In Combat, George J. Annas
Protecting Soldiers From Friendly Fire: The Consent Requirement For Using Investigational Drugs And Vaccines In Combat, George J. Annas
Faculty Scholarship
In 1990, following Iraq's invasion of Kuwait, the Department of Defense (DOD) sought a waiver of the informed consent requirements of existing human experimentation regulations from the Food and Drug Administration (FDA). With this waiver, DOD could authorize military use of investigational drugs and vaccines on soldiers involved in the Gulf War without their informed consent. The basis of the waiver request was military expediency. In DOD's words: "In all peace time applications, we believe strongly in informed consent and ethical foundations... but military combat is different." DOD's rationale was that informed consent under combat conditions was "not feasible" because …

Department of Electrical and Computer Engineering: Faculty Publications (to 2015)
In the paper, we present simulation results for the 13 channel DS CDMA WATM LAN utilising optimized complex spreading signatures based on Walsh- Rademacber functions. The method to obtain those optimized spreading signatures, as well as the full set of the coefficients giving the minimum level of crosscorrelation between any pair of the channels is shown. The resultant system BER as well as the distribution of errors within WATM cells is given. The obtained results indicate that with the application of a hybrid ARQ scheme, capable of correcting 10 errors, the number of WATM cells which would require retransmission is …

Hopwood, Bakke And The Future Of The Diversity Justification, Lackland H. Bloom Jr.
Faculty Journal Articles and Book Chapters
The decision of the Court of Appeals for the Fifth Circuit in Hopwood v. Texas sent shock waves through the academic community with its holding that the Equal Protection Clause of the Fourteenth Amendment prohibited the University of Texas Law School from taking account of race as a factor in its admissions process. In the course of invalidating certain procedures employed by the law school, the Fifth Circuit concluded that Justice Powell's influential opinion in Regents of the University of California v. Bakke, which recognized the pursuit of diversity in higher education as a compelling state interest, had never constituted …
Instructional Technology In The School System, Sherri Sue Zanotti
Instructional Technology In The School System, Sherri Sue Zanotti
Graduate Research Papers
Analyses of the deployment of technology in schools have tended to note its failure to affect the daily values and practices of teachers and students. This absence is generally regarded as an implementation failure, or as resulting from some temperamental shortcoming on the part of the teachers or technologists. Such a construction is predicated on the assumption that the technology is value free and its implementation a struggling playing field. This paper proposes that no instructional technology is ever neutral. Its value and practices must support the organization into which it is placed. The failures of technology to look and …

Mach-Zehnder Interferometer Fringe Projector For Variable Resolution Video Moire, Phillip C. Kalmanson, August Schutte, Chris L. Hart, Joel H. Blatt
Aerospace, Physics, and Space Science Faculty Publications
A Mach-Zehnder based variable resolution fringe projection system has been built for 3-D video moini machine vision. This system uses the three main advantages of the Mach-Zehnder - 1) There is no optical feedback to the laser source, 2) The interfemmeter can accept two different laser wavelengths simultaneously, and 3) The interferometer produces two orthngonal output beams. The lack of optical feedback makes the Mach-Zehnder especially attractive for use with high power laser diode sources which are sensitive to optical feedback. When the two input ports axe used with two different wavelength lasers, the target can be illuminated by simultaneous …

The Effect Of Temperature Dependent Frequency Factor On The Evaluated Trapping Parameters Of Tsl Glow Curves, A. N. Yazici, Z. Öztürk
The Effect Of Temperature Dependent Frequency Factor On The Evaluated Trapping Parameters Of Tsl Glow Curves, A. N. Yazici, Z. Öztürk
Turkish Journal of Physics
The effect of temperature dependency on frequency factor and its relationship to trapping parameters is discussed by using the peak shape method. The coefficients appearing in the peak shape formula for the calculation of the activation energy have been determined and tabulated for the symmetry factor $\mu_g(X)$ for $x=0.50$ and 0.75 of the peak intensity. It is found that significant errors occur in the value of the trapping parameters if the temperature dependecy of the frequency factor is not consider.
Photoconductivity Studies Of Crystalline Si:H P-I-N, Ruhi Kaplan, Bengü Kaplan
Photoconductivity Studies Of Crystalline Si:H P-I-N, Ruhi Kaplan, Bengü Kaplan
Turkish Journal of Physics
Optically modulated photoconductivity (PC) properties of hydrogenated crystalline silicon (c-Si:H) with p-i-n junctions were investigated by frequency-resolved spectroscopy in the temperature range 20-290 K. The PC lifetime measurements of c-Si:H p-i-n show a second lifetime distribution which only dominates at low temperature under low illumination levels of excitation. Unlike the room temperature single lifetime distribution seen in c-Si:H p-i-n, the maximum of this second lifetime distribution shifts to longer times when the excitation intensity decreases, which reconciles with non-geminate pair recombination and thus the distant-pair model. In addition to lifetime measurements, the direct current-voltage (I-V) characteristics, the excitation light intensity- …
Analytical Expressions Of Matrix Elements For Saxon-Woods Potential And Pad'{E} Approximations, Valentin L. R. Niculescu, Dumitru Catana
Analytical Expressions Of Matrix Elements For Saxon-Woods Potential And Pad'{E} Approximations, Valentin L. R. Niculescu, Dumitru Catana
Turkish Journal of Physics
The paper presents the analytical matrix elements of the kinetic hamiltonian in the oscillator base. The Pad'{e} approximations for the potential part (Saxon - Woods and alike) was used. From residue calculus the potential matrix elements are analytical. Many parts of these expressions can be computed once for ever. In this way the evaluation time can be reduced and the relations obtained are well suited for parallel computation.
Domain Structures Of Epitaxial Perovskite Ferroelectric Films: Part Ii. Applications, S. Pamir Alpay, Alexander L. Roytburd
Domain Structures Of Epitaxial Perovskite Ferroelectric Films: Part Ii. Applications, S. Pamir Alpay, Alexander L. Roytburd
Turkish Journal of Physics
The use of domain stability maps for epitaxial perovskite ferroelectric films is illustrated with some examples. The equilibrium domain structure and domain fractions as a function of temperature are predicted for PbTiO_3(001) films grown epitaxially on three different substrates: MgO(001), KTaO_3(001), and SrTiO_3(001). Misfit dislocation formation at the growth temperature is found to have a profound effect on both the domain selection and relative domain populations. Theoretical predictions are compared with available experimental data.

^{19}F Nmr Study Of Flux-Line Dynamics In Fluorinated Yba_2cu_4o_8, Figen Tabak, Mavrizio Corti̇
Turkish Journal of Physics
Measurements of the ^{19}F NMR linewidth \Delta \nu and spin-lattice relaxation rate 1/T_1 have been performed in an oriented powder sample of fluorinated YBa_2Cu_4O_8 at temperatures 4 < T < 300 K and static magnetic fields 0.3 < H_0 < 9.4 T for Hollc. Thermal motion of flux lines was evidenced from the effect on NMR linewidth while 1/T_1 showed the effects due to interaction with Fermi liquid.
