The paper introduces a description of CPM signals by a state-space model. Based on this model, a noncoherent demodulation method of CPM signals, that uses an Extended Kalman Filter (EKF), was developed. The performances of the demodulation method were tested on two types of CPM modulated signals, embedded in noise: Minimum Shift Keying (MSK) and Gaussian Minimum Shift Keying (GMSK). The results, obtained from simulations performed in MATLAB, leaded to the conclusion that, for moderately low Signal to Noise Ratios (SNR), the EKF algorithm provides satisfactorily even good results in noncoherent demodulation of CPM signals.","PeriodicalId":239366,"journal":{"name":"2010 12th International Conference on Optimization of Electrical and Electronic Equipment","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115007083","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 paper, starting from the relations that describe the dynamical behaviour for each subsystem of an automotive powertrain, a nonlinear state-space model for a drivetrain with backlash was developed.

For the particular values of the flow and head, the turbine tends to run most efficient at a particular speed. Often, the generator needs to be rotated at a speed greater than the turbine optimum speed. Therefore, a speed increaser is needed in many cases to link the turbine to the generator. The paper analyzes the influence of introducing a speed increaser between a Turgo turbine and the generator. The generator is tested on experimental stands in order to find the mechanical characteristics. Then, the synthesis of the chosen planetary speed increaser is performed. The paper presents the dynamic modeling of the turbine-speed increaser-generator assembly; the working point in steady state regime is established. The validation of the theoretical results using Matlab - Simulink software guarantees the good functioning of the physical prototype of small hydropower plant in certain conditions.","PeriodicalId":239366,"journal":{"name":"2010 12th International Conference on Optimization of Electrical and Electronic Equipment","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132150608","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}

By altering functionality in different places of the testbench, potential hidden errors can be detected, improving the testbench capacity to detect design misbehavior. The fault injection in SystemVerilog testbench components may be used in addition to existing methods of functional verification analysis, for testbench validation.

Commercially available proprietary software of LIMS allow user to only save the measurement data into files of their formats; and it is not readable and shared the chromatogram in other formats. AMCOS allows user to acquire the data of HPLC and store the measured data into the centralized database of CONSYS, which is a open source webbased system. CONSYS allows users to retrieve data without using proprietary software and producing both XML and XLS file formats, thus, can be viewed and shared by other CONSYS users.
