The modeling using various polynomial structures and the parameter identification of the plant, the controller and the sensor are performed with the emphasis on the plant. Since the goal is to predict the operating condition where the system is tripped and causing the disruption in electricity generation of the plant, the validation of the model is demonstrated against the hard conditions, where rapid changes of system load causing the system tripped events occurred. Due to the limitation on the existing data acquisition system causing the low resolution on the quality of the collected data, two data treatment processes are introduced and compared, i.e., the linear interpolation with delay and the Piecewise Cubic Hermits Interpolating Polynomial (PCHIP) technique for the best performance selection. The model parameters are estimated and compared based on a least squares criteria. The controller is configured based on the adapted PI controller of the actual system. The performance of proposed system models are given in terms of root-mean-square error (RMSE). Based on the simulation results, it is found that the 2nd-order polynomial model with linear interpolation with delay is the most promising and delivers us the satisfactory performance under both normal load changing and during the tripped event.","PeriodicalId":110627,"journal":{"name":"2016 IEEE International Conference on Automation, Quality and Testing, Robotics (AQTR)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121113557","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}

Part of the approach is a streaming curvature feature calculation. The investigated approach utilizes a particle filter to incrementally update pose estimates during data acquisition. The method is evaluated in real data experiments with a high-precision laser striper system attached to an industrial robot. During the laser scan, the data is integrated on-the-fly in order to calculate features and based on these to estimate the object's pose. Experiments show the method's competitiveness in accuracy and reliability compared to state-of-the-art offline algorithms.","PeriodicalId":110627,"journal":{"name":"2016 IEEE International Conference on Automation, Quality and Testing, Robotics (AQTR)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126167396","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 resonant converter is designed to achieve zero voltage switching (ZVS), whilst secondary synchronous rectification (SR) reduces even more the total power losses.

High-level faults of any multiplicity are assumed to be present, however, there is no need to enumerate them. A novel concept of test groups which has the goal to prove the correctness of a part of the system's functionality instead of keeping track of fault coverage during test generation as in the traditional case is elaborated. The method can be regarded as a generalization of the logic level test pair approach for identifying fault-free wires in gate-level networks to a high-level identification of fault-free functional blocks. To cope with the complexity of multiple fault masking mechanisms, high-level decision diagrams are used. A method for optimizing test length was developed with no negative impact on the immunity regarding possible fault masking, and the estimates of the gain in test length were given.","PeriodicalId":110627,"journal":{"name":"2016 IEEE International Conference on Automation, Quality and Testing, Robotics (AQTR)","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132734228","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}

Identification of species represents a key aspect to expose commercial frauds implemented by substitution of valuable species with others of lower value. Fish species identification is mainly performed by morphological identification of gross anatomical features of the whole fish. However, the increasing presence on markets of new little-known species makes morphological identification of species difficult. In this paper we present FishAPP, a cloud-based infrastructure for fish species recognition. FishAPP is composed of a mobile application developed for the Android and the iOS mobile operating system enabling the user to shot pictures of a whole fish and submit them for remote analysis and a remote cloud-based processing system that implements a complex image processing pipeline and a neural network machine learning system able to analyze the obtained images and to perform classification into predefined fish classes.

These signals are collected from the skin surface and used indirectly as reference signals for the controller of the prostheses. Due to the nature of these signals it is impractical to feed these signals as inputs directly into the controller. The signals should be processed first, by segmentation, features extraction and features processing. Since only a limited number of muscles are used (usually two or three) a one-to-one correspondence between a muscle and a joint of the prosthesis cannot be established. Thus, the myoelectric control is unnatural, requires long periods for training and involves a great mental effort for the patient. We propose a reference signal generator (RSG), which is an interface module that receives the movement intentions of the patient and generates the position and speed reference signals for the controller. By means of the RSG the burden of the patient is reduced drastically and in the same time the safety in using the prosthesis is increased.","PeriodicalId":110627,"journal":{"name":"2016 IEEE International Conference on Automation, Quality and Testing, Robotics (AQTR)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115234343","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}
