Real-Time Three-Dimensional Occupancy Grid Modeling for the Detection and Tracking of Construction Resources

Awareness of the construction environment can be improved by automatic three-dimensional (3D) sensing and modeling of job sites in real time. Commercially available 3D modeling approaches based on range scanning techniques are capable of modeling static objects only, and thus cannot model dynamic objects in real time in an environment comprised of moving humans, equipment, and materials. Emerging prototype video range cameras offer an alternative by facilitating affordable, wide field of view, dynamic object tracking at frame rates better than 1?Hz (real time). This paper describes a methodology to model, detect, and track the position of static and moving objects in real time, based on data obtained from video range cameras. Experiments with this technology have produced results that indicate that video rate 3D data acquisition and analysis of construction environments can support effective modeling, detection, and tracking of project resources. This approach to job site awareness has inherent value and broad application. In combination with effective management practices and other sensing techniques, this technology has the potential to significantly improve safety on construction job sites.

针对实时相关运动模式挖掘应用的需求,提出了一种实时地发现关闭蜂群模式的簇重组算法(CLUR).该算法维护一个候选蜂群模式列表,在每个时间戳采用基于密度的聚类算法对移动目标进行聚类,根据聚类结果组合所有的最大移动目标集,记录相应的时间集,然后构建候选蜂群模式,并更新到候选列表.算法给出了三种更新规则和一种插入规则,用于实现候选蜂群模式列表的更新,同时降低了候选列表的冗余度,提高了算法的效率.在每个时间戳结束时可通过关闭检测规则实时地发现当前时刻的关闭蜂群模式.在合成数据上的综合实验验证了CLUR算法的正确性、实时性和高效性,CLUR算法适用于实时相关运动模式挖掘系统.     

Automation of data acquisition and of experiment control: application to the study of sleep-wake cycles and behavioral paradigms

The low cost of microcomputers allows them to be dedicated full time to data acquisition and analysis of experimental paradigms. The usual interfaces required for such interaction with the experiment are briefly explained, namely, analog-to-digital converters, input-output control lines and real time clocks. Some basic concepts on the use of microcomputers for the automation of data acquisition and control are summarized, including the characterization of waveshapes, the structure of data storage and on-line data reduction. Off-line, the matrices generated by the data acquisition program become the input for ad-hoc processing programs. Precision, flexibility and fluidity of analysis are outstanding advantages of computer controlled setups. A system for automation of sleep studies and a system for automation of scheduled-controlled behavior are presented as working examples.

Time-frequency distribution methods for the analysis of click-evoked otoacoustic emissions

Click-evoked otoacoustic emissions (CEOAEs) are time-varying signals with a clear frequency dispersion along with the time axis. Analysis of CEOAEs is of considerable interest due to their close relation with cochlear mechanisms. The particular structure of CEOAEs requires a time-frequency method with both a satisfactory time and frequency resolution. In this paper, several basic time-frequency distribution methods are considered and compared on the basis of both simulated signals and real CEOAEs. Results from simulations and real CEOAEs revealed that the wavelet approach is highly suitable for the analysis of such signals. Some examples of the application of the Wavelet Transform to CEOAEs are provided here. Applications range from the extraction of normative data from adult OAEs to the extraction of quantitative parameters for clinical purposes.     

Statistical Analysis on the Cost and Duration of Public Building Projects

A probabilistic model is proposed to predict the risk effects on time and cost of public building projects. The research goal is to utilize a real history data in estimating project cost and duration. The model results can be used to adjust floats and budgets of the planning schedule before project commencement. Statistical regression models and sample tests are developed using real data of 113 public projects. The model outputs can be used by project managers in the planning phase to validate the schedule critical path time and project budget. The comparison of means analysis for project cost and time performance indicated that the sample projects tend to finish over budget and almost on schedule. Regression models were developed to model project cost and time. The regression analysis showed that the project budgeted cost and planned project duration provide a good basis for estimating the cost and duration. The regression model results were validated by estimating the prediction error in percent and through conducting out-of-sample tests. In conclusion, the models were validated at a probability of 95%, at which the proposed models predict the project cost and duration at an error margin of ±0.035% of the actual cost and time.
