However, OFDM suffers from high Peak-to-Average Power Ratio (PAPR) problem. In literature, there are various PAPR reduction techniques among them only; Active Constellation Extension (ACE), Tone Reservation based on Null Subcarriers (TRNS), and Partial Transmit Sequence (PTS) whose can work as downward-compatible techniques, i.e. receivers doesnt have to be modified. Generally, PAPR reduction techniques are required to have downward compatibility, no data rate loss, no Side Information (SI), small computational complexity, and large PAPR reduction gain. However, no one of them has all these requirements and no PAPR reduction technique can be considered as the best among others. Thus, recent trend in this field is to make hybridization between different PAPR reduction techniques in one scheme, to gain the advantages of two or more conventional techniques. In literature, there are plenty of hybrid PAPR reduction techniques. Among them, only hybrid ACE- PTS that has downward compatibility, however its downward compatibility depends on channel estimation and the used application. In this paper we propose hybrid ACE- TRNS that is downward compatible technique regardless the used application and independent of channel estimation. Results showed that, for different modulation schemes, ACE- TRNS has PAPR reduction performance better than that of ACE-PTS, with less computational complexity.","PeriodicalId":197824,"journal":{"name":"2018 International Japan-Africa Conference on Electronics, Communications and Computations (JAC-ECC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123115569","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}

Object tracking systems need to reduce their energy consumption because the technology is increasingly being utilized for battery-operated systems, e.g., driving assist systems, smartphones, drones and so on. To tackle this problem, dynamic frame-rate optimization has been proposed. This approach optimizes the frame-rate on the basis of target object speed by taking into account the energy trade-off between the image capturing and tracking processes. In order to improve tracking accuracy, the approach selects a frame-rate based on a specific fixed value. However, the required parameters are different depending on the scene and content of the input video. In this paper, we propose a method to adaptively select parameters. Simulation results show the energy consumption is reduced by up to about 65.0%, and 45.0 % on average without critical tracking accuracy degradation.","PeriodicalId":197824,"journal":{"name":"2018 International Japan-Africa Conference on Electronics, Communications and Computations (JAC-ECC)","volume":"192 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115559865","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}

Our approaches are based on sparse representations over a learned dictionary and denoising auto-encoders, which have provided best state of the art results for natural images denoising. The experiments show that those two algorithms are promising in document denoising, as they provide the ability of learning a prior knowledge of clean character models to use them in the denoising process.","PeriodicalId":197824,"journal":{"name":"2018 International Japan-Africa Conference on Electronics, Communications and Computations (JAC-ECC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123610385","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}

Four current mirror topologies are designed and simulated in both FinFET and HKMG bulk CMOS technologies. For low input currents, simulation results of FinFET-based CMs show better mirroring accuracy, higher output resistance and bandwidth as well as lower power consumption. On the other hand, HKMG bulk CMOS based CMs shows lower input resistance and input compliance voltage for simple CM, cascode CM, regulated cascode CM and self-biased cascode CM.","PeriodicalId":197824,"journal":{"name":"2018 International Japan-Africa Conference on Electronics, Communications and Computations (JAC-ECC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125282299","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}

Another technique is combining both word level and character level features. Recently, deep architectures based on character level features only showed more enhanced performance. In this paper two deep CNNs are applied for Arabic sentiment analysis using character level features only. A large scale dataset is constructed from available SA datasets in order to train networks. The dataset maintains opinions from different domains expressed in different Arabic forms (Modern Standard, Dialectal). Besides different machine learning algorithms as Logistic Regression, Support Vector Machine and Naïve Bayes have been applied to assess the performance on such a large dataset.
