Domain-oriented knowledge-acquisition tools provide e cient support for the design of knowledge-based systems. However, the cost of developing such tools is high, especially when their restricted scope is taken into account. Developers can use metalevel tools to generate domain-oriented knowledge-acquisition tools that are custom tailored for a small group of experts, with considerably less eff...

background and objective: obstructive sleep apnea (osa) is a disease with serious consequences. many portable devices have been developed to overwhelm some of limitations in the accessibility of the gold standard test for osa, polysomnography (psg). this study aimed to determine diagnostic accuracy of a portable sleep apnea screener against psg in patients of a sleep clinic. materials and metho...

A concise survey of recent developments in multimedia communications and applications is first presented. The report then focuses upon the more specific research area of the low-power multimedia portable systems. Two typical low-power multimedia portable systems, Camcorder and Mobile phone hand set, are proposed to act as case studies for codesigning low power multimedia systems. Finally, a sum...

Process measurement is one of the most important tasks in the whole control system. It is determined by the fact that control accuracy is fully dependent on how preciously measuring chain works. Present-day there is available number of devices performing data acquisition tasks – standard cards for PCI or ISA bus which are suitable for standard personal computers and its industrial versions and ...

A three-dimensional (3-D) shape measurement system that can simultaneously achieve 3-D shape acquisition, reconstruction, and display at 30 frames per second (fps) with 480,000 measurement points per frame is presented. The entire processing pipeline was realized on a graphics processing unit (GPU) without the need of substantial central processing unit (CPU) power, making it achievable on a po...

The advent of integrated microsystems for genetic analysis allows the acquisition of information at unprecedented length and time scales. The convergence of molecular biology, chemistry, physics, and materials science is required for their design and construction. The utility of the microsystems originates from increased analysis speed, lower analysis cost, and higher parallelism leading to inc...

Due to the mechanical and beam optics requirements, the geometry of the LHC dipole cold masses is submitted to very tight tolerances (few tenths of millimeters) over the magnet’s length (more than 15 meters). Different parts of the cold mass have to be either measured or properly positioned throughout the assembly (see reference [1]), implying the use of a portable system. The measurement syste...

One of the most promising methods of interacting with small portable computing devices such as personal digital assistants is the use of handwriting. However, for data acquisition touch sensitive pads, which are limited in size, and special pens are required. In order to render this communication method more natural Munich & Perona 11] proposed to visually observe the writing process on ordinar...
