The Role of Web Services at Home
The increase in computational power and the networking abilities of home appliances are revolutionizing the way we interact with our homes. This trend is growing stronger and opening a number of technological challenges. From the point of view of distributed systems, there is a need to design architectures for enhancing the comfort and safety of the home, which deal with issues of heterogeneity, scalability and openness. By considering the evolution of domotic research and projects, we advocate a role for web services in the domestic network, and propose an infrastructure based on web services. As a case study, we present an implementation for monitoring the health of an elder adult using multiple sensors and clients
Does Health Class Affect Students\u27 Decision Making?
The effectiveness of high school health education curriculum which is evaluated through anonymous student response in a behavior and life style survey that is given before students take health education and again after they have taken health education to determine if they have made changes in their decision making and lifestyle choices
Radially and azimuthally polarized non paraxial Bessel beams made simple
We present a method for the realization of radially and azimuthally polarized
nonparaxial Bessel beams in a rigorous but simple manner. This result is
achieved by using the concept of Hertz vector potential to generate exact
vector solutions of Maxwell's equations from scalar Bessel beams. The scalar
part of the Hertz potential is built by analogy with the paraxial case as a
linear combination of Bessel beams carrying a unit of orbital angular momentum.
In this way we are able to obtain spatial and polarization patterns analogous
to the ones exhibited by the standard cylindrically polarized paraxial beams.
Applications of these beams are discussed.Comment: 8 Pages, 4 Figure
