Life cycle assessment (LCA) is a systematic method of analyzing the environmental load of a product and evaluating potential environmental effects. It can be useful for eco design and for dealing with environmental regulations. However, the LCA process generally requires considerable time and money to collect relevant life cycle inventory (LCI) data and information. Usually, enterprises develop a new product by revising or reusing a similar previous product. Repeating the LCI data collection whenever they develop a new product is very cumbersome and will increase lead time. However if we estimate the eco impact values based on the previous design, then the efforts related to LCI data collection and its attending complex computational procedures are reduced. Although various efforts have been made on the streamlined LCA in an effort to overcome these limitations, the result is still unsuitable for practical eco design. We therefore propose an approximate LCA method using case-based reasoning (CBR) for a rapid and convenient environmental evaluation in product development. For the approximate LCA, we developed function behavior structure environmental effect (FBSE) representations and a creative similarity measurement based on FBSE for a clear and consistent CBR process. A geometry attribute based linear modeling algorithm of eco impact is proposed to replace complicated LCA procedures, and genetic algorithms are used to search for optimal solutions to satisfy the proposed model. A case study involving an upstream process of a vehicle air purifier fan confirms that the proposed CBR for LCA method can be effectively applied to eco product design.","PeriodicalId":191166,"journal":{"name":"2013 IEEE International Conference on Automation Science and Engineering (CASE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131453808","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}

Krovi","doi":"10.1109/CoASE.2013.6654047","DOIUrl":"https://doi.org/10.1109/CoASE.2013.6654047","url":null,"abstract":"In this paper, a novel random matrix approach is utilized to characterize the uncertainty propagation in the articulated robotic systems. This method permits the probabilistic formulation to take into account the complexity and structural inter-dependencies of the kinematic manipulators. However, conventional random variable/vector based approaches are unable to address this issue. The kinematic Jacobian matrix of the manipulator is probabilistically formulated so that it adopts a random symmetric positive definite perturbation matrix. The density function of the perturbation matrix is constructed using maximum entropy principle that yields a Wishart distribution with specific parameters. The only information used in the construction of the Jacobian matrix probability model are mean and a scalar value dispersion parameter. We propose to use this framework to study the propagation of the uncertainties in both serial and parallel manipulators. Parallel architecture manipulators offer superior manipulation accuracy and structural rigidity compared to serial chain manipulators but feature more complex physical layout and limited workspace. Therefore, for the design purposes, a trade off between two different architectures is required. This necessitates the mathematical characterization of their capability with respect to the uncertainty propagation. As a case study, the developed random matrix method is implemented on a planar RRR serial and a planar 3-RRR parallel manipulator, that are performing an identical task. A Monte Carlo analysis is conducted and the statistics of the response of both systems provides appropriate measures to compare their dexterity dealing with the uncertainties. The final results verify superiority of the parallel architecture.","PeriodicalId":191166,"journal":{"name":"2013 IEEE International Conference on Automation Science and Engineering (CASE)","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133577165","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}

Also, an increasing quantity and diversity of environmental sensors are being added to smart buildings to ensure the quality of services provided by the building. The need for particulate matter (PM) sensors in consumer devices such as air purifiers, is an example where manufacturing advances have made the sensors much less expensive than laboratory equipment. Beyond their original intended use, air quality, they can also be used for occupancy monitoring. The work presented in this article proposes to use a low-cost (<; 8 USD) PM sensor to infer the local movement of occupants in a corridor by sensing the resuspension of coarse (≥ 2.5 μm) particles. To obtain meaningful values from the inexpensive sensors, we have calibrated them against a laboratory-grade instrument. After calibration, we conducted a 7.8 hour experiment measuring coarse PM within a pedestrian corridor of a heavily-used office area. Comparing against ground truth data obtained by a camera, we show that the PM sensor readings are correlated with human activity, thus enabling statistical methods to infer one from the other.","PeriodicalId":191166,"journal":{"name":"2013 IEEE International Conference on Automation Science and Engineering (CASE)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115394081","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}

Often it is of interest to monitor the states of unbalances while the rotor is running in order to prevent damages to the rotor system. For the model based unbalance monitoring a rotor model is required to represent the behavior of the rotor system and the influences of the unbalances. The feasibilities of the methods are often limited by the accuracy of the system model. Accurate physical model is often hard to build especially for large scale rotor systems with unknown physical properties. In case of rotor systems with large discs, the gyroscopic effect is not negligible. It results in a rotary frequency dependent system behavior and thus makes the modeling problem more complicated. Besides the modeling problems, disturbances from initial unbalances and rotor bow are also issues to be considered in the unbalance monitoring. In this paper we formulate the disturbances and gyroscopic effect as unknown inputs, which are widely investigated in the fault detection processes and use the model of non-rotating rotor as basis for the unbalance monitoring. Augmented observer, which takes sinusoidal vibrations into consideration is used for the unbalance monitoring. The application of the method on a rotor test rig is presented in this paper.","PeriodicalId":191166,"journal":{"name":"2013 IEEE International Conference on Automation Science and Engineering (CASE)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123045907","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}
