The "information age" has finally produced tools capable of supporting a variety of employment and business models that previously were infeasible. The convergence of socio-economic factors, workforce composition, accelerating product obsolescence and technological advances has created an unparalleled need and fertile opportunity to redefine the workforce model. These new technological capabilities alone are insufficient to reinvent the business models. Management must, through vision and solid commitment at all hierarchical levels, migrate its values, reinvent precepts, coalesce processes, and redefine its workforce models to remain financially viable in the emerging compressed timelines. The tools are at hand; economic realities make corporate change a financial requirement; and the changing values, goals and social composition of the workforce apply pressure to create a new, network centric workforce model. These converging pressures make rethinking the corporation viable and necessary. How rapidly these changes occur will be determined now by old-fashioned rates of human I corporate acceptance of change. Compression of the market timeline may force significant, perhaps unrecoverable fallout among those companies that are slow to take up this challenge.

Describes a model-based moving target signature synthesis and analysis tool that leverages and integrates separate simulations for scenario generation, signature prediction, and moving target video phase history (VPH) synthesis with platform, sensor and target modeling. The integration provides a high-fidelity simulation that features computer-aided design (CAD) target models, electromagnetic scattering prediction codes, arbitrary target/sensor imaging geometries, aerospace sensor and platform modeling, and the specification of entity dynamics including interaction with terrain and road network data. The tool is ideal for generating moving target scenarios and data for the development and performance evaluation of radar-based automated ground target tracking and classification algorithms.

In this paper a new sliding mode flux and speed observer is proposed for induction machine drive systems. The error between the actual and observed currents converges to zero which guarantees the accuracy of the flux observer. The rotor speed and the rotor time constant are estimated based on the estimated stator currents and rotor flux. The estimated rotor time constant is used in slip calculation and observer structures and the estimated speed is used as feedback to the speed regulation. Computer simulation results of the speed control verify the validity of the proposed speed estimation algorithm.

The paper considers a direction finding system consisting of two squinted antennas that functions both as an interferometer and as an amplitude comparison system. The interferometer spacing is such that ambiguities exist, and a statistical analysis is used to describe the performance of using the amplitude based angle to select the correct ambiguous angle of incidence. The statistical analysis is at the system level so that no particular hardware implementation need be considered.

In this paper, a performance comparison of a recently developed fuzzy data association algorithm for multitarget tracking (MTT) with the well known joint probabilistic data association (JPDA) algorithm is presented. In this scheme, a fuzzy logic multiple models algorithm is constructed first. It uses different target models like constant velocity, constant acceleration etc. to describe all the states of the system. A Kalman filter is set up for each model to estimate their states. The final state estimate is a weighted average of the model conditioned estimates with the fuzzy reasoning. Based on this algorithm and after constructing the corresponding rule set, a fuzzy data association algorithm is developed, which uses full states, prior knowledge and experience. The simulation scenario considers both the fuzzy and JPDA algorithms for tracking two and four targets in a two dimensional setting. Based on the simulation results, the advantages and disadvantages of both the approaches for MTT are presented.

A Fuzzy Logic Controller (FLC), with a Dynamically Focussed Learning (DFL) algorithm is proposed, developed and implemented to improve the performance of an induction motor drive system. In standard direct fuzzy controller, utilization of the rule-base is mostly poor, especially when error input gets smaller and the control action is produced by only a few rules in the center of the rule-base. With such a small number of rules, the fuzzy controller performs inadequately because the resulting control surface can capture very approximate control actions. This poor utilization of the rule-base may degrade the controller performance. A possible solution to this problem may be to redesign the rule-base such that the rule base has move rules at the center. However, this solution limits the ability of the controller to a limited input range and specific inputs. Instead, a DFL fuzzy controller is proposed, which ensures that the fuzzy controller can utilize the entire rule base by auto-tuning algorithm. Computer simulation and experimental results on a 5 hp induction machine are presented to substantiate the proposed scheme.

Wind tunnel tests are generally obstructed by model support with limitations. The development of magnetic suspension wind tunnel (MSWT) is designed to free the model from conventional mechanical supports. Under precise model design, a roll motion with appropriate control can be implemented in MSWT. This paper presents a modification of NCKU 10 cm/spl times/10 cm MSWT to accomplish the roll motion control in wind tunnel tests. The modification of this experiment includes position and attitude sensing and test model design. The position and attitude sensing is improved and set-up by a laser-optical circuit, quadrant detectors and dual-lateral detector in x-axis to ensure accurate measure. The rolling inertia is generated from a rotating mass inside the test model. With very careful design, a rocket model is fabricated for experiments. A passive PID control is implemented to achieve the predictable constant roll motion on the test model. A current feedback loop is applied to strengthen the control stability. Being different from other MSWT applications, the test model is locked by the position and attitude sensing via feedback control loop. Due to the accomplishment of motion test roll only constant speed in good control limitations, demonstrates performance. The idea of this study is to extend dynamic test capability in the magnetic suspension wind tunnel, and bring further valuable applications.
风洞试验通常受到有限制的模型支撑的阻碍。磁悬浮风洞(MSWT)的开发旨在将模型从传统的机械支撑中解放出来。在精确的模型设计下,可以在MSWT中实现适当控制的滚动运动。为了实现风洞试验中的横摇运动控制,对NCKU进行了10 cm/spl次/10 cm MSWT的改进。本实验的修改包括位置姿态感知和试验模型设计。采用激光光学电路、象限检测器和x轴双侧检测器对位置和姿态传感进行了改进和设置,保证了测量的准确性。滚动惯量是由试验模型内部的旋转质量产生的。经过精心设计,制作了一个火箭模型用于实验。采用无源PID控制,实现对试验模型的可预测的恒横摇运动。采用电流反馈回路加强控制的稳定性。与其他MSWT应用不同的是,测试模型是通过反馈控制环进行位置和姿态感知锁定的。由于在运动试验中只能完成恒速滚转的良好控制限制,论证了其性能。本研究的目的是拓展磁悬浮风洞的动态测试能力,并带来更多有价值的应用。

In this paper, we investigate human face recognition for facial images involving a high degree of in-plane and out-of-plane 3D distortions such as rotation. In the proposed technique, we investigated the problem of invariant face recognition by considering four different classes of images. A small subset of images is used for every class to create a composite image, which represents each class. The proposed technique is implemented by using fringe-adjusted filter based joint transform correlator (JTC) technique due to its superior performance over alternate JTCs and the feasibility of its implementation in the optical domain. Furthermore, the utilization of synthetic discriminant function to generate the composite image for enhancing the correlation output is also investigated. Computer simulation results are presented to show the validity of the proposed technique.

The AMS (Alpha Magnetic Spectrometer) experiment is designed to search for the antimatter components of cosmic rays, the products of the annihilation of dark matter particles and to perform additional cosmic-ray measurements like spectrum of light nuclei, antiprotons and positrons as well as isotopic composition for light elements. The complete AMS instrument will be installed on the International Space Station (ISS) in year 2003. A preliminary version of the apparatus has flown in June 1998 on the Space Shuttle mission STS-91. The power supply system of the tracker, described in this paper, has been constructed optimizing noise performances, following space qualification criteria for a ten day mission on the shuttle and considering the operation in the fringe magnetic field of the spectrometer. This paper also includes a short description of tracker electronics. Optimisation and qualification tests on the complete power supply system are reported. Even if most of the paper refers to the Shuttle flight version of the paper supply, guidelines for the design of the ISS flight version are given in the conclusions.
