Decomposition of acceleration was investigated as an alternative to commonly used direct spectral analysis of measured acceleration or angular velocity for tremor quantification. An orientation estimation algorithm was devised to decompose the measured acceleration into the gravitational artifact and the inertial acceleration caused by sensor movement in an inertial reference frame. Resulting signals, beside the measured acceleration and angular velocity, were used to assess tremor amplitude and frequency by spectral peak detection. The algorithm was tested on experimental data from a clinical study including patients with essential tremor. The testing comprised of the classification of measurements to come from a patient or a healthy control and of the regression of the visual assessment of tremor amplitude. Small improvements in performance measures were achieved by using the decomposed acceleration. The regression accuracy was comparable to the accuracy achieved in other works. The influence of sensor calibration and connections of results to an analytic approach were analyzed briefly. © 2010 Elsevier Ltd. All rights reserved.

This paper presents the communication related design considerations of Wireless Sensor Network (WSN) aided Multi-Robot Simultaneous Localization and Mapping (SLAM). In this approach, multiple robots perform WSN-aided cooperative SLAM using only range values to landmarks in the environment by measuring the Received Signal Strength Indicator (RSSI) of the received radio messages, and odometry information. The SLAM algorithm proposed in this study uses the Rao-Blackwellized Particle Filters. In addition, the inherent communication problems in WSNs, and their effects on cooperative SLAM are explained in detail and shown with the results of The Network Simulator (ns-2) simulations. © 2011 IEEE.

Abstract To meet the increasing environmental and efficiency requirements, the possibilities to improve the performance of a 25 kW th wood pellet boiler by utilizing PLC and feedback control are investigated. The process is first stabilized by improving the grate sweeping sequence, which originally disturbs the process. Prior to continuous combustion control development, the process is analyzed and identified. After sequential control improvements the combustion behaves well but tends to drift. A PID controller was designed to enable drifting compensation. It is shown that improved grate sweeping sequence and continuous feedback control provide a major improvement for system performance cost effectively.

Bringing manufacturing excellence and innovation into balance, like yin and yang, in mature multi-product semiconductor fabrication facilities is the scope of the paper. This is done with the new approach called "Design for Flow by 3" which includes Product Process of Record (POR), Production control, and organizational Design for Flow. It is derived out of the challenge to face the increasing pressure to combine efficiency goals and the speeding up of innovation. Therefore, industry specific approaches of optimization are left behind to adapt new ones from other industries. As a result, an iterative introduction of flow production, fulfilling the aforementioned requirements is depicted. © 2011 IEEE.

One of the prerequisites for AFM based nanomanipulation is that the position of the target nanoparticle can be stable controlled within a known area, while this prerequisite is still hindered by the uncertainties including the initial position of the nanoparticle and of the AFM tip, together with the uncertain forces from the substrate and so on. In this paper, a Stochastic Pushing (SP) model and a Stable Pushing Strategy are proposed respectively, which can push the nanoparticle into a bounded target area within a given probability. Simulations and experiment based on the proposed SP model demonstrate the validity of the Stable Pushing Strategy. © 2011 IEEE.

In this paper we present a method for reconstructing static scene viewed through thick smoke using multiple images. Based on spatiotemporal statistical approach our method works well on noisy videos containing swirling smoke. We apply statistical analysis on regions of color input images, and show the way to reconstruct scene by transforming images to alter mean and deviation locally. We introduce a method to extract necessary parameters using multiple frames of a video. We verify our method with the widely used physical model of aerosols, highlighting some differences from removing haze and fog - a widely studied area. Furthermore, our approach eliminates the need for complex optimization, making real-time processing possible. Results show that our method is capable of reconstructing scene in challenging cases. © 2011 IEEE.

The stability and reliability of the intelligent terminal's receiving information affects its control of intelligent switch in operation directly. To achieve reliable intelligent communications terminals, with techniques and methods of IEC61850 modeling, the paper completed the 126KVGIS intelligent terminal information model based on the analysis of its information characteristics, and established the hardware platform with data model and logical nodes provided by IEC61850. Thus it has a certain practical significance to promote the standard construction, operation and management of intelligent substation, and lead the digital process of process layer devices.

A tracking simulator that runs in parallel with the plant and perfectly simulates the plant behavior has been developed. This tracking simulator is currently in the validation phase at a commercial plant site. The tracking simulator strongly depends on the physical model based on physical and chemical laws, and it cannot simulate unknown phenomena in the plant. A hybrid model consisting of a physical model and a statistical model using the historical plant operation data was proposed. The estimation accuracy of the statistical model was improved using the virtual input from the tracking simulator. Although the Kalman filter technique is applied to conventional software sensors for quality estimation as a model updating function, deterioration of estimation accuracy is often seen with marked changes in plant behavior and the analyzers shut down. To resolve these issues, we applied Just-In-Time modeling based on the historical data modeling technique with the tracking simulator, and the plant model coverage of the tracking simulator was expanded for various processes. © 2011 IFAC.
