This study describes the physical, psychological and social context of rheumatoid arthritis (RA) pain from the male veterans. A qualitative, descriptive design was employed using a purposive sampling to ensure representation of male veterans. Interviews were conducted with 12 male veterans of the VA Greater Los Angeles Healthcare System. Socio-demographic characteristics, clinical profiles and ...

In this paper, model reference neural network structure is used as a controller for vibration suppression of the Euler–Bernoulli beam under the excitation of moving mass travelling along a vibrating path. The non-dimensional equation of motion the beam acted upon by a moving mass is achieved.  A Dirac-delta function is used to describe the position of the moving mass along the beam and its iner...

Single-walled carbon nanotubes (SWNTs) possess fascinating electrical properties and offer new entries into a wide range of novel electronic applications that are unattainable with conventional Si-based devices. The field initially focused on the use of individual or parallel arrays of nanotubes as the channel material for ultra-scaled nanoelectronic devices. However, the challenge in the deter...

The subject of collaboration comes up frequently within the Canadian and international Geomatics communities. The reasons for seeking more collaborative approaches within our field are clear: we stand to become more successful in our projects, programs, research efforts and business pursuits. As Geomatics practitioners, we are also better positioned to play a leadership role in meeting the chal...

Synopsis The Medicare program must contend with serious challenges as it enters its 50th anniversary year, including rising expenditures, a fragmented, confusing benefit structure, and inadequate financial protections for some low-income beneficiaries and high users of services. In part 2 of their report, David Blumenthal, M.D., Karen Davis, and Stuart Guterman examine these challenges and disc...

THIS SURVEY HIGHLIGHTS SOME important trends in AI research and development, focusing on perceiving and affecting the real world. We will primarily address robotics, but we certainly don’t intend to imply that this is the only important area of AI research and development in the 21st century. We see tremendous importance in the continuing work in such areas as data mining, learning, knowledge r...
