Blade selection for a modern axial-flow compressor
The procedures leading to successful design of an axial flow compressor are discussed. The three related approaches to cascade selection are: (1) experimental approach which relies on the use of experimental results from identical cascades to satisfy the velocity diagrams calculated, (2) a purely analytical procedure whereby blade shapes are calculated from the theoretical cascade and viscous flow equations, and (3) a semiempirical procedure which used experimental data together with the theoretically derived functional relations to relate the cascade parameters. Diagrams of typical transonic blade sections with uncambered leading edges are presented
Tearing Down the Wall: How Transfer-on-Death Real-Estate Deeds Challenge the Inter Vivos/Testamentary Divide
This Article will examine one of the most recent will substitutes, the transfer-on-death (“TOD”) real-estate deed. Nearly half of the states have recognized, through common-law forms or legislation, a mechanism to allow for the transfer of real property on death without using a will, without following the will formalities, and without necessitating probate. This new tool in the estate planner’s toolbox is invaluable: revocable trusts have proven too expensive for decedents of modest means, and wills continue to require formalities that can easily frustrate non-lawyer-drafted estate documents. But the variety of TOD deed rules and mechanisms that the different states have adopted has led to disparity and uncertainty in form and outcome, resulting in litigation and frustration of decedent’s intent.
We believe this uncertainty and frustration will continue as even more states adopt the Uniform Real Property Transfer on Death Act (“URPTODA”), which purports to stabilize the law and facilitate testamentary intent. States grappling with this new form interpose significant differences, and lawyers and judges are not all on the same page as to the consequences. One source of confusion is the URPTODA’s provision that TOD deeds are non-testamentary and, at the same time, the Uniform Act provides that the property rights do not transfer until death.
Although it is one thing to declare that TOD deeds are non-testamentary even though property rights don’t transfer until death—which in itself goes against centuries of formal legal rules—it is quite another to get all the other legal consequences to fall into place accordingly. For instance, would a state’s anti-lapse statute apply to save a beneficiary designation if the deed is deemed non-testamentary, even though the intent is to have the real property transfer upon death?
In our opinion, the TOD deed pushes the juridical binary of inter vivos and testamentary transfers beyond coherence and rationality. The law of will substitutes has already undermined the rationality of maintaining the divide, and in this Article, we will argue that the time has finally come to reject the division between inter vivos and testamentary transfers and seek a rational and holistic set of tools and formalities to gain the benefits of probate avoidance that will substitutes provide with the ease of control and full revocability of wills. Elevating form over functionality, although a characteristic of the common law, inevitably disserves the interests of those who cannot afford lawyers who can easily draft around the sometimes-arcane distinctions between testamentary and inter vivos transfers to gain the benefits of each while avoiding the burdens

Transverse imaging of the proton in exclusive diffractive pp scattering
In a recent paper (hep-ph/0608271) we describe a new approach to rapidity gap
survival (RGS) in the production of high-mass systems (H = dijet, Higgs, etc.)
in exclusive double-gap diffractive pp scattering, pp -> p + H + p. It is based
on the idea that hard and soft interactions are approximately independent (QCD
factorization), and allows us to calculate the RGS probability in a
model-independent way in terms of the gluon generalized parton distributions
(GPDs) in the colliding protons and the pp elastic scattering amplitude. Here
we focus on the transverse momentum dependence of the cross section. By
measuring the "diffraction pattern," one can perform detailed tests of the
interplay of hard and soft interactions, and even extract information about the
gluon GPD in the proton from the data.Comment: 4 pages, 2 figures, uses ws-procs9x6.cls. Proceedings of XIV

Angular Power Spectrum of the Microwave Background Anisotropy seen by the COBE Differential Microwave Radiometer
The angular power spectrum estimator developed by Peebles (1973) and Hauser &
Peebles (1973) has been modified and applied to the 2 year maps produced by the
COBE DMR. The power spectrum of the real sky has been compared to the power
spectra of a large number of simulated random skies produced with noise equal
to the observed noise and primordial density fluctuation power spectra of power
law form, with . Within the limited range of spatial scales
covered by the COBE DMR, corresponding to spherical harmonic indices 3 \leq
\ell \lsim 30, the best fitting value of the spectral index is with the Harrison-Zeldovich value approximately
0.5 below the best fit. For 3 \leq \ell \lsim 19, the best fit is . Comparing the COBE DMR at small to
the at from degree scale anisotropy experiments
gives a smaller range of acceptable spectral indices which includes .Comment: 22 pages of LaTex using aaspp.sty and epsf.sty with appended

y-scaling in Quasielastic Electron Scattering from Nuclei
A relativistic single particle model is used to calculate the inclusive
reaction from 12, 40, 56, 197, and 208 nuclei in the quasielastic
region. We have shown that this model provides a very good description of the
available experimental cross sections when they are dominated by the
quasielastic process. In this paper we use this model to investigate the
dependence of -scaling on electron kinematics, particularly the electron
scattering angle, for a range of squared four momentum transfer
(GeV/c). In this kinematic domain, Coulomb distortion of the electron does
not significantly affect scaling, but final state interactions of the knocked
out nucleon do affect scaling particularly when the nucleons have lower
energies. In general, we find that scaling works for this reaction, but at
lower values of the four momentum transfer, the scaling function does have some
dependence on the electron scattering angle. We also consider a modification of
y-scaling to include small binding energy effects as a function of Z and A and
show that there is some improvement in scaling.Comment: 21 pages, 11 figure
Higher Order Modulation Equations for a Boussinesq Equation
In order to investigate corrections to the common KdV approximation to long
waves, we derive modulation equations for the evolution of long wavelength
initial data for a Boussinesq equation. The equations governing the corrections
to the KdV approximation are explicitly solvable and we prove estimates showing
that they do indeed give a significantly better approximation than the KdV
equation alone. We also present the results of numerical experiments which show
that the error estimates we derive are essentially optimal
