computerized three-dimensional models based on the Visible Human Project do reflect rich anatomical details, but up to now, they do not allow for the representation of the knowledge of acupuncture, an important component of Traditional Chinese Medicine. In this paper, original work for 3D representation of acupoints and acupuncture treatment is reported. This is based on the dataset of the male Visible Human, the computerized 3D models provided by VOXEL-MAN as well as the anatomic knowledge based on our systematic research work. The model contains the spatial description resulting from segmentation, graphic modeling, volume visualization and localization of acupoints, and a linked knowledge base, which is a hierarchical structure providing detailed knowledge of Chinese medicine. A 3D anatomical atlas of acupuncture based on this model is almost finished and generally available.

We now apply the model predictive control (MPC) of speed limits that we have presented in previous publications to a calibrated METANET model of a 19 km stretch of the real-world freeway A1 in The Netherlands. This freeway regularly suffers from shock waves originating mainly from on-ramps, and speed limits are now used to suppress these shock waves. First, we calibrate and validate the extended METANET model with data from the A1 freeway, and we use the Delft OD method to estimate the origin-destination patterns that are needed for the simulation of the destination oriented traffic. Next, we verify from data whether the necessary conditions for applying speed limits against shock waves are satisfied. We show that the MPC controller performs well even under the assumption that the traffic demand is not known on the on-ramps and is known for only a few kilometers upstream and downstream of the controlled stretch. This approach results in an improvement of the total time spent in the network with about 15%.

Aboard current ships, such as the DDG 51, engineering control and damage control activities are manpower intensive. It is anticipated that, for future combatants, the workload demand arising from operation of systems under conditions of normal steaming and during casualty response will need to be markedly reduced via automated monitoring, autonomous control, and other technology initiatives. Current DDG 51 class ships can be considered as a manpower baseline and under Condition III typical engineering control involves seven to eight watchstanders at manned stations in the Central Control Station, the engine rooms and other machinery spaces. In contrast to this manning level, initiatives such as DD 21 and the integrated engineering plant (IEP) envision a partnership between the operator and the automation system, with more and more of the operator's functions being shifted to the automation system as manning levels decrease. This paper describes some human systems integration studies of workload demand reduction and, consequently, manning reduction that can be achieved due to application of several advanced technology concepts. Advanced system concept studies in relation to workload demand are described and reviewed including. Piecemeal applications of diverse automation and remote control technology concepts to selected high driver tasks in current DDG 51 activities. Development of the reduced ship's crew by virtual presence system that will provide automated monitoring and display to operators of machinery health, compartment conditions, and personnel health. The IEP envisions the machinery control system as a provider of resources that are used by various consumers around the ship. Resource needs and consumer priorities are at all times dependent upon the ship's current mission and the availability of equipment pawnbrokers.

Multiresolution representation of quadrilateral surface approximation (MRQSA) is a useful representation for progressive graphics transmission in networks. Based on two requirements: (1) minimum mean square error and (2) fixed reduction ratio between levels, this paper first transforms the MRQSA problem into the problem of solving a sequence of near-Toeplitz tridiagonal linear systems. Employing the matrix perturbation technique, the MRQSA problem can be solved using about 24mn floating-point operations, i.e. linear time, if we are given a polygonal surface with (2m-1)×(2n-1) points. A numerical stability analysis is also given. To the best of our knowledge, this is the first time that such a linear algebra approach has been used for solving the MRQSA problem. Some experimental results are carried out to demonstrate the applicability of the proposed method. © 2002 Kluwer Academic Publishers.

The resolution of a conventional ultrasound system is limited by the pulse length and beam width, and significant improvement is possible by deconvolution of the ultrasound RF signal. Most previous research has been based on the assumption that the medium response was real valued. However, a complex-valued medium response incorporates the phase of the carrier wave and provides a more comprehensive and appropriate mode] even though the deconvolution becomes substantially more difficult because the problem is inherently underdetermined. To address this problem, an iterative algorithm, the least squares method with point count regularization (LSPC) was developed and presented. Simulations and experiments were used to examine the performance of the algorithm, and excellent results were obtained and reported. Further study of the algorithm to reduce computational complexity and to improve robustness is in progress. © 2002 IEEE.

Exploiting Speculative Value Reuse Using Value Prediction 02

Exploiting Speculative Value Reuse Using Value Prediction

Data dependencies between instructions greatly impede instruction-level parallelism. Recently two hardware techniques -Value Prediction and Value Reuse - have been proposed to overcome the limits imposed by data dependencies. We introduce a new hardware scheme for exploiting speculative value reuse by using value prediction. We propose a new microarchitecture which uses value prediction to provide speculative value reuse. We use Value Prediction to predict operands of all integer ALU instructions and all load/store instructions. Value Reuse - including speculative and non-speculative reuse - is used for repeating instructions. Repeating instructions, which are found by a value reuse test, are those instructions which are executed repeatedly with the same input values and produce the same results. We use execution-driven simulation to evaluate the performance of our scheme. On average, we found ～9% speedup over a baseline architecture and ～84% correctly predicted speculative value reuse in speculative reuse lookup operations (～5.7% of executed instructions).

This paper describes a neural computation approach to independent component imaging of disease signatures. The novel feature is to separate mixed imagery sources blindly over an informative index subspace. The recovery of patterns is achieved by independent component analysis, whose parameters are estimated using the infomax principle. We discuss the theoretic roadmap of the approach, and its applications to the partial volume correction in cDNA microarray expression and the neuro-transporter binding separation in positron emission tomography.

A Neocognitron-like neural network built with universal feature planes, called shape cognitron (S-cognitron) is introduced to classify clustered microcalcifications (MCCs). The S-cognitron is composed of two modules. The first module consists of (a) a shape orientation layer, to convert first-order shape orientations into numeric values, and (b) a complex layer to extract second-order shape features. Following is a 3-D figure layer to extract the shape curvatures. It is then followed by a second module made up of a feature formation layer and a probabilistic neural network (PNN)-based classification layer, to construct "potential" high-order shape features and perform the classification. Experimental results show the promise of the system.
