We present a hardware architecture for parallel innerproduct array computation in very high dimensional feature spaces, towards a general-purpose kernel-based classiJer and function approximator: The architecture is internally analog with fully digital interface. On-chip analog jinegrain parallel processing yields real-time throughput levels for high-dimensional (over 1,000per chip) classificat...

We simulate Shor's algorithm on an Ising spin quantum computer. The influence of non-resonant effects is analyzed in detail. It is shown that our " 2πk "-method successfully suppresses non-resonant effects even for relatively large values of the Rabi frequency. The quantum Shor algorithm [1] provides an exciting opportunity for prime-factorization of large integers – a problem beyond the capabi...

In this paper we study the resource requirements of electrooptical organizations in performing digital computing tasks. We define a generic model of parallel computation using optical interconnects, called the optical model of computation (OMC). In this model, computation is performed in digital electronics and communication is performed using free space optics. Using this model we derive relat...

The present paper concerns a relation between digital contractibility and the exist...

The practice of diagnostic x-ray imaging has been transformed with the emergence of digital detector technology. Although digital systems offer many practical advantages over conventional film-based systems, their spatial resolution performance can be a limitation. The authors present a Monte Carlo study to determine fundamental resolution limits caused by x-ray interactions in four converter m...

We give necessary and sufficient conditions for the existence of a continuous extension from a smallest-neighborhood space (Alexandrov space) X to the Khalimsky line. Using this result, we classify the subsets A ⊂ X such that every continuous function A → Z can be extended to all of X. We also consider the more general case of mappings X → Y between smallest-neighborhood spaces, and prove a dig...

The ability to resolve 2ne picture detail is of paramount importance in medical imaging systems for viewing small tissue, bone structure and anatomy in X-ray images. In this paper, we present a new digital radiographic image processing system with the property of scalability and adaptability. (i) A new automatic optimization algorithm is proposed for display. (ii) An adaptive detection of a reg...

Digital radiography has become an indispensable diagnostic tool in dentistry today. To improve vision and diagnosis, dental x-ray software allows image enhancement (eg, adjusting color, density, sharpness, brightness, or contrast). Exporting digital radiographs to a file format compatible with commercial graphic software increases chances that information can be altered, added, or removed in an...
