Securely Consume Web Services Using PHP
The PHP: Hypertext Preprocessor language (PHP) has evolved to a sophisticated mainstream programming language for rapid development of significant Web applications at major sites including Facebook.com, Wikipedia.org and Yahoo.com. Leading software vendors such as Oracle and IBM are rushing in providing tools that bridge their products to PHP. However, we have observed a gap in facilitating PHP to utilize Web services efficiently. This thesis reports our efforts in design and implementation of PHP applications that consume Web services. In doing so, I have proposed a framework facilitating PHP programs to utilize Web services with high performance capability. In addition, a number of Web service standards including WS-Addressing and those in WS-Security are integrated into my PHP implementation. Examples of using various Amazon Web Services are provided with details

Adsorption properties and third sound propagation in superfluid He films on carbon nanotubes
We consider the adsorption properties of superfluid He films on carbon
nanotubes. One major factor in the adsorption is the surface tension force
arising from the very small diameter of the nanotubes. Calculations show that
surface tension keeps the film thickness on the tubes very thin even when the
helium vapor is increased to the saturated pressure. The weakened Van der Waals
force due to the cylindrical geometry also contributes to this. Both of these
effects act to lower the predicted velocity of third sound propagation along
the tubes. It does not appear that superfluidity will be possible on
single-walled nanotubes of diameter about one nm, since the film thickness is
less than 3 atomic layers even at saturation. Superfluidity is possible on
larger-diameter nanotube bundles and multi-walled nanotubes, however. We have
observed third sound signals on nanotube bundles of average diameter 5 nm which
are sprayed onto a Plexiglass surface, forming a network of tubes.Comment: 4 pages, accepted for Journal of Physics: Conference Series
