In this paper, we consider the problem of automated position estimation using a wireless network of inexpensive binary motion sensors. The challenge is to incorporate data from a network of noisy sensors that suffer from refractory periods during which they may be unresponsive. We propose an estimation method based on particle filtering, a numerical sequential Monte Carlo technique. We model sensors with conditional probability density functions and incorporate a probabilistic model of an intruder's state that utilizes velocity. We present simulation and experiments with passive infrared (PIR) motion sensors that suggest that our estimator is effective and degrades gracefully with increasing sensor refractory periods.","PeriodicalId":116108,"journal":{"name":"2006 IEEE International Conference on Automation Science and Engineering","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124272460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this scenario you have cooperative subjects, large time capture windows, and staff to edit and mark up data as necessary. However, as biometrics moves from the laboratory these factors impinge upon the scalability of the system. In this work we developed a prototype biometric tunnel for the capture of non-contact biometrics. The system is autonomous to maximise subject throughput and self-contained to allow flexible deployment and user friendliness. Currently we deploy 8 cameras to capture the 3D motion (specifically gait) and 1 camera to capture the face of a subject. The gait and face information thus extracted can be used for subsequent biometric analysis. Interaction between the various system components is performed via the use of an agent framework. Performance analysis of the current system shows that we can currently achieve a moderate throughput of 15 subjects per hour. Additionally, analysis performed upon the biometric features extracted from a small population show them to be potent for recognition","PeriodicalId":116108,"journal":{"name":"2006 IEEE International Conference on Automation Science and Engineering","volume":"2011 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114797391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of the study is for fixture loading planning, which is to plan the applying force on a workpiece to move it into the fixture. The system incorporates the dynamics simulation engine with the haptics interaction. The dynamics simulation engine uses a time stepping method with Guass-Seidel algorithm for resolving the forces on multiple contacts. The haptics interaction is performed in two modes: no contact mode and contact mode. To reach the high updating rate required for haptics simulation (1 KHz), we use two computers for the simulation, and the data is exchanged through a network connection.

Blocking flow is a kind of phenomenon occurring frequently in the emergency network(EN). When the network is blocked, there are various saturated flows and different flow distribution of arcs. The value of the saturated flow and its expended time from the source to the sink are important indices to evaluate the system reliability for ENs. We try to evaluate the system reliability that the saturated flow of the network is not less than the demand d and the flow capability per unit time is not less than the threshold coefficient lambda0. Based on the saturated model, we simulate the probability of the different arc flows. An algorithm based on the blocking cutset of the EN is proposed to evaluate the network reliability.

However, the existing computational method of correlation integral curve is very time-consuming, which makes the promising control strategy fail to be used for real-time application. A fast algorithm of the curve computation is presented based on the concept of segmentation in this paper. The improved method is much faster than the existing one for all reduplicate computation of the number of correlated pairs is eliminated using our proposing propositions and criterions. Applying the improved method to some cases of our experiment, it is demonstrated that the correlation integral had a remarkable drop of about 0.25 order of magnitude prior to the development of surge and the elapsed time is much shorter than the requisite time of the existing method. The fast algorithm will motivate the real-time application of correlation integral curve to the control system using the value as the feedback threshold, which will extend the normal operating range of the centrifugal compressor.","PeriodicalId":116108,"journal":{"name":"2006 IEEE International Conference on Automation Science and Engineering","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127787337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The existing computation methods in the literature depend on the complete siphon enumeration of a net. Since the number of minimal siphons grows in general exponentially with respect to the size of a net, it is difficult to compute all the SMS. This paper proposes a fast algorithm to find a set of elementary siphons for an L-S3PR based on partial SMS from a structural perspective. We show an approach to obtain a minimal siphon from a resource circuit. The concepts of the complementary matrix and independent arcs in a resource directed graph are proposed, which are important in our method. We describe the method of computing independent arcs in details. Then an algorithm to find a set of elementary siphons for an L-S3PR is developed.
