Because the structure and function of a high-rise building is complex and the density of occupants in it is high, fire safety is still a worldwide difficult problem. Safety and timely evacuation is an important issue under fire in the high-rise buildings. Because it is impossible in fact to do experiments about fire safety evacuation in high-rise buildings, in this paper, a research framework based on the artificial system, computational experiments, and parallel excution (ACP) theory is proposed. First, an evacuation process is considered to compose of two stages including pre-evacuation stage and evacuation stage. Second, artifical men with recognition functions based agent technology is proposed. Finally, computational experiments are designed by using an orthogonal experiment table, and experiment procedure of pre-evacuation stage is given. The idea of systimatic research about the influence of fire control facilities to evacuation is also proposed © 2011 IEEE.

Mobile information systems (MIS) are finding their way into private and business every-day activities. There are also increased attempts to establish MIS for on-site activities in industrial facilities. Industrial environments, however, place significantly higher demands on mobile user interfaces than office or home environments. Common interaction styles are often unsuitable for this domain. MIS comprising specialized configurations like wearable systems might overcome current limitations. Wearable systems make it possible to arrange system components in the immediate environment of the user's body in order to create an ergonomic and intuitive user interface. However, the use of distributed, body-worn user interfaces, and in particular separation of input and output devices, might increase the workload for the user. This study examines the extent to which the separation of input and output devices affects the workload for wearable MIS. Three interaction styles in two different configurations are investigated with four different measures to determine the workload covering both objective and subjective indicators. This investigation shows that there is no significant increase of workload in general. However, the measurement of the heart rate variability revealed subtle but significant differences between the two configurations, particularly for one interaction style. These findings indicate that physiological measures can provide more detailed and subtle information about additional workload and its source than other measures. © 2011 ACM.

Highly accurate geometric correction for seriously oblique aero remote sensing image based on the piecewise polynomial model

Most widely used geometric correction methods rely on ground control points to empirically determine a mathematical coordinate transformation to project the distorted image into the reference image. However, conventional methods usually employed the same correction formula in the whole image which few considered the seriously geometric distortion problem causing by imaging with a large view angle. This paper introduces a new piecewise polynomial correction method that addresses this problem based on the nonlinear variability of geometric distortions in different imaging angles. In the new method, piecewise strategy and the selection of control points are two key techniques. The seriously oblique image is partitioned into several subspaces which separately use the different correction factors in order to correct the local distortions better. And in the correction, a uniform distribution strategy is proposed for selecting the representative control points to evaluate the correction polynomial coefficients of each subspace. The experimental results show that the proposed correction method is significantly outperforming conventional approaches. For an image acquired in 60 degrees, the proposed method results in correction root mean square errors having around 30% improvement comparing to the traditional method.

Simulation method for three-dimensional atmospheric turbulence in virtual test

Atmospheric turbulence is an important issue for successful flight in aeronautical experimentation. In the virtual test of aircraft, building a three-dimensional atmospheric turbulence field (3D-ATF) is necessary for integral simulation. Most classical methods which were based on building one-dimensional atmospheric turbulence simulation do not suit simulating the 3D-ATF. And several existing 3D-ATF simulation methods were not applicable in a large 3D space. This paper that addresses these problems proposes a new method for generating 3D-ATF based on the correlation function. The recursive formulae for the generation of 3D-ATF are deduced based on the self-correlation function and one step correlation function, and the original 3D-ATF is obtained. To achieve the good statistical characteristic the original 3D-ATF is optimized by the twice filtering. The new method is applied to build a 400 × 400 × 400 atmospheric turbulence field. Simulation results indicate that the relativity of 3D-ATF based on the correlation function method is near to the theoretic value. And the relativity of the 3D-ATF optimized by filtering performs the better fitting characteristics to the theoretic value. Consequently, the proposed simulation method is effective for building 3D-ATF in virtual test of aircraft. Copyright © 2011 Binary Information Press.

In terms of the difficulty of vehicle tracking in complex environment of the visual surveillance system, an object tracking algorithm is proposed for the applications in practical visual surveillance systems for intelligent traffic. A block-based Gaussian mixture background modeling method for object detection is presented to reduce the computational complexity of moving vehicle object abstraction. An adaptive tracking algorithm fused with color features and texture features is described to better adapt the traffic scene variation. The experimental results show that the proposed algorithm can effectively deal with the complex urban traffic conditions and the tracking performance is better than the conventional particle filter method and single feature based non-adaptive object tracking method.

There are more and more needs for surface contact works, such as polish, grinding, paint, inspection, etc., with robot manipulators in recent years. In this paper, to achieve high-speed and high-precision surface contact work by robot manipulator, we propose a separation method of posture components to solve the problem of the rotation order, and a method of introducing the impedance characteristics to hybrid position, posture, force and moment control to eliminate the interference between free space and constrained space. Furthermore, the effectiveness of our control method for surface contact work was verified by the dynamic simulation of character-erasing motion on the white board of 6-DOF robot manipulator. © 2011 IEEE.

This paper addresses the problem of robust control of spatially interconnected systems (SISs) subject to both exogenous disturbances and time-varying norm-bounded parameter uncertainties. A sufficient condition to the well-posedness, stability and attractiveness of an SIS with respect to all admissible uncertainties is presented in terms of a set of matrix inequalities. For the synthesis of distributed dynamic output feedback controllers, the nominal system is expanded in its output space so as to eliminate the uncertainties in the system matrices. In reference to the standard distributed scaled H_(infinity) control, the synthesis of distributed robust H_(infinity) controllers is proposed based on the system model in the expanded space. Numerical examples validate the effectiveness of the method.

Global Positioning System (GPS)-equipped probe vehicles have been one of the principal techniques in detection of traffic flow. In order to guide the application of the different methods using data from GPS probe vehicles, this paper compares two of the most popular methods using the GPS data to estimate traffic state- the method of tracking probe vehicles, and the one of fitting the model with the sample points of probe vehicles. In the experiment, data from thousands of GPS-equipped taxies were taken as the probe vehicles, and the estimate accuracy and operation speed of the two different methods were systematically measured. For the accuracy experiment, the ground truth was obtained by replaying the videos which were shot on 24 links in Shanghai downtown. The experiment results illustrate that the tracking-based method usually bears higher estimate accuracy, and slower operation speed, compared to the model-fitting method. © 2011 ASCE.

The solution to the problem of finding the reaction kinetic realization of a given system obeying the mass action law containing the minimal/maximal number of reactions and complexes is shown in this paper. The proposed methods are based on Mixed Integer Linear Programming where the mass action kinetics is encoded into the linear constraints. Although the problems are NP-hard in the current setting, the developed algorithms give a usable answer to some of the questions first raised in [1].
