To detect lung nodules usually classical X-ray and/or computed tomography (CT) images are used. The progression of the disease can be monitored if the doubling time of the volume of a pulmonary nodule is determined and followed, which means that the volume of a nodule has to be measured/estimated. To measure the nodule volume using classical X-ray images is almost impossible, while a CT-based diagnosis is rather expensive. Recently a new radiological image-based modality, digital tomosynthesis (DTS) has been developed. DTS can be considered as a 2.5D modality, where coronal slice images of a chest can be computed. The spatial resolution of a DTS image is much higher than that of a CT image, while the thickness of a slice is larger compared to a CT image. Thus DTS can also be used to determine lung nodule volumes although -because of the 2.5D reconstruction - volume estimation is a rather hard task. This paper proposes a new way for estimating nodule volume. The method was developed using an experimental database, which contains reconstructed images of 16 simulated small, elliptical nodules, placed into an anthropomorphic chest phantom, and was evaluated by a few real DTS images and an image base made from simulated projections from a public CT database.","PeriodicalId":424006,"journal":{"name":"2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123549723","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}

Nevertheless a key driving point in bringing on the market some innovation resides in the opportunity to implement a flexible sensing system able to optimize the existing compromise among performance, safety, reliability, availability and maintenance (RAMS) parameters. This problem can be solved addressing the possible fall back strategies in case of single or multiple sensors failures through reliability and availability modeling. In this paper, an approach on the modeling of actual sensor configuration dynamic apportionment is presented by means of phase diagrams representation, with the aim of evaluating the advantages and the drawbacks linked to the choice of a certain sensing configuration despite of the sensor technology and relying on failure modes and failure and repair rates knowledge. The simulation results are presented for three different possible sensors configurations on a selected sensor monitoring chain used in gas turbine systems.","PeriodicalId":424006,"journal":{"name":"2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124646154","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}

A design scheme of the optimization of the input electrical impedance matching with the transmission system of the multivariate sensor based on the bond graph modeling approach is proposed. Bond graph models of each constituent component within the transmission system are established, where parameters regarding the properties of the piezo-material, layer thickness, and input electrical impedance could be manipulated easily. The effects of different combinations of capacitor and inductor that constitute the input electrical circuit are investigated. An optimal combination for electrical impedance matching is determined through bond graph simulation. This optimal solution improves the design of sensor circuits with the capability of generating the highest output gain or increasing the transmission distance under the same electrical excitation, meanwhile ensuring that the received signal has high signal-to-noise-ratio (SNR) for further parameter retraction. Bond graphing has been shown as an effective approach for guiding the design of complex, cross-domain, and embedded sensing systems.","PeriodicalId":424006,"journal":{"name":"2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128506974","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}

Actually the ETCS Level 1 and 2 provide the train integrity and localization functionalities by using track circuits and/or axle counter systems: the problem of these solutions is represented by the high cost of track circuit and axle counter installation, taking into account even the related equipment management. This paper shows the study, design and realization of an innovative method to detect the train integrity, by using the wireless technology. the reference scenario is referred to ERTMS / ETCS (European Rail Traffic Management System / European Train Control System), which defines the modalities for the exchange of signalling information between the track side and on board rail vehicle. In particular, reference is made to a ground subsystem (SST) that implements the ETCS Level 3 only. The designed wireless system is referred to a general freight train that don't have the electric energy on board or at least a low power of energy: for each wagon a logic of vehicle has been implemented to manage the information, instead the communication between neighbouring wagons has been managed by a wireless loop communication, standardized by the IEEE 802.15.4 standard. The definition of a board logic to realize the train integrity represents an innovation respect the actual state of art technology, that does not consider this thematic. At the end, a graphic interface has been developed so as to verify the functionality and the diagnostic characteristics of the proposed control logic.","PeriodicalId":424006,"journal":{"name":"2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127433974","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}
