The body of work on emotion detection from speech signal is relatively limited. Nowadays, researchers are yet augmenting on what features effects the identification of emotion in speech. There is a significant ambiguity as to the finest algorithm for emotion's classification, and which emotions to class together as well. In this work, we seek to address these matters. We use Support Vector Machines (SVMs) and Artificial Neuron Network (ANN) to classify opposite emotions. There is a variability of temporal and spectral characteristics that can be extracted from human speech. We focus only on Mel Frequency Cepstral Coefficients (MFCCs) as inputs to the classification algorithms. The classification reports obtained from the conducted experiments allow us to say that, for the given parameters, the ANN model was better detecting the speech carried emotional information than the SVM.","PeriodicalId":216138,"journal":{"name":"2019 International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115366929","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 equalization phase ensures good transmission within these channels. Equalizers are digital filters designed to adaptively track channel variations for a very low computing cost. The adaptation is done on the flow of information, using statistical knowledge a priori on the data emitted. To remedy the long-distance communication problems such as attenuation of the signal, the satellite type transmission channels is preferred. This paper deals with the modeling of a 3-order satellite communication channel also the identification of its equalizer using the S-PARAFAC Volterra model and the Alternating Recursive Least Squares (ARLS) algorithm.","PeriodicalId":216138,"journal":{"name":"2019 International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114621795","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}

Two observers are used in this method. Indeed, a time-delay fractional Luenberger observer is generated to detect fault. An adaptive fractional order with time delay observer is then constructed to estimate the fault by providing an on-line estimation algorithm. The convergence criteria of this observer is expressed via linear matrix inequalities (LMIs) by the use of a specific Lyapunov function considering the continuous frequency disturbed model. The validity of the fault detection and estimation technique is shown by a numerical example.","PeriodicalId":216138,"journal":{"name":"2019 International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116251573","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}

To avoid such accident in Skikda Refinery steam generators, a HAZOP risk assessment method was chosen to identify the various possible deviations of the system, their causes and consequences on humans, facilities and the environment. A quantification of major risks at the 1050G1 steam generator was performed with the Phast software to estimate the distance effects and consequences of such accidents and to implement suitable means of prevention and mitigation.","PeriodicalId":216138,"journal":{"name":"2019 International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125383425","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}

Generally, the temperature and solar radiation is not constant and thus affects the output of our panel. Furthermore, we proposed a sliding mode control for our chopper, which will leads to the maximum power point tracking (MPPT).

The performance is determined in terms of Bit Error Rate (BER). Increasing the number of Bits/symbol provides an increase of BER both the ZF and MMSE detectors for an antennas array 50 × 100; Whereas increasing the number of OFDM sub-carriers provides a decreasing of BER. Combining 128-QAM modulation with 1024-sub-carriers and increase the receiver antennas array three times (i.e., 50 × 300), decreases more the BER both the ZF and MMSE detectors.
