In this scenario, an important issue is to assess the stability of the microgrids taking into account the network and currents dynamics that are also affected by the control parameters. This paper shows how a dynamic phasor approach can be used to derive a closed loop model of the microgrid and then to perform an eigenvalues analysis that highlights how instabilities arise for suitable values of the frequency droop control parameter. Further, it is shown that the full order system is well approximated by a reduced order system which captures the inverters phase and line currents dynamics.","PeriodicalId":168063,"journal":{"name":"2014 IEEE 11th International Multi-Conference on Systems, Signals & Devices (SSD14)","volume":"290 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131998152","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}

It is now possible to add, modify, or remove important features from an image without leaving any perceptual traces of tampering. With more than several million pictures uploaded daily to the net, and the introduction of e-Government services, it is becoming important to develop robust detection methods to identify image tampering operations. To this end, image forensics techniques aim at restoring trust and acceptance in digital media by uncovering tampering methods. Such detection techniques are the focus of this paper. In particular, we provide a survey of different forging detection techniques with a focus on copy and move approaches.","PeriodicalId":168063,"journal":{"name":"2014 IEEE 11th International Multi-Conference on Systems, Signals & Devices (SSD14)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130312499","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 research, we identify the pattern of the simulated earthquake signal from the mobile phone accelerometer via machine learning. Before the data is processed into the classifier, static windowing and denoising was done to boost up the accuracy. Another fractal features are extracted from the pre-denoised data, which are the box counting dimension feature and the Hurst coefficient. The purpose of doing static windowing is to obtain more features so that we can have many potential useful attribute candidates as possible. Denoising with symlet wavelet is done to remove the noises which can worsen the classification accuracy. The classification is done using support vector machine and multilayer perceptron classifier with the accuracy of 81% and 82.15%, respectively.","PeriodicalId":168063,"journal":{"name":"2014 IEEE 11th International Multi-Conference on Systems, Signals & Devices (SSD14)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115191688","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 change of the power source is sometimes not possible or involves effort and costs. If the node needs to be accessible for communication at any point of time it must have a radio in permanent receive state. This depletes the battery in a few days. The contradiction between long lifetime and permanent accessibility can be solved by using a separate wake-up receiver on the node. In this work we present a sensor node with included wake-up receiver working in the 433MHz ISM band. Our solution consumes 2.8 μA of current in sleep state while still maintaining a realtime behaviour. The low current consumption is achieved by modulating a 125 kHz wake-up signal on the 433MHz carrier in the sender. In the receiving node a passive demodulation circuit extracts the wake-up signal and feeds it to an 125 kHz low frequency receiver IC. An additional 16 bit address coding is used for an selective wake-up of nodes.","PeriodicalId":168063,"journal":{"name":"2014 IEEE 11th International Multi-Conference on Systems, Signals & Devices (SSD14)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122108874","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}

For that reason, it is of great interest to use such phones to replace magnetic cards. This paper uses the built-in Xenon flashlight in today's Android smartphones to experimentally transmit the data stored on the user magnetic card to a card reader or automatic teller machine (ATM). We experimentally modulate the embedded Xenon flashlight in a smartphone with the required information of a traditional magnetic card and transmit the light over a secure high speed optical link at 15 bps with no additional hardware at the user end. The paper introduces the design of an implemented small, inexpensive supplementary receiver circuit module, which is easily attached to a contemporary card reader or ATM machine. Furthermore, the paper tests the system performance under the effect of interference from another transmitter as well as compares its speed and security to the regular ATM card and to other competing technologies.","PeriodicalId":168063,"journal":{"name":"2014 IEEE 11th International Multi-Conference on Systems, Signals & Devices (SSD14)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126276520","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 real world, most WSNs application scenarios expect from wireless sensor nodes (WSns) to be often inactive and to remain idle when no communication is present. Accordingly, this inactivity is completely useless and brings nothing but wasting energy. It has been agreed that the very first scope focused on reducing the power consumption is to handle this loss. The waste of power is mainly due to the idle listening of the main transceiver. Turning it off disconnects the node from the network and makes it inaccessible. That's how the challenge is raised. To cope with that, several solutions have been conducted in the recent years. One of which, suggests using an ultra-low power radio receiver referred as Wake-Up Receiver (WuRx). Its purpose is to handle the idle listening while keeping the main radio completely off. The reason behind, is the power consumption of the WuRx, which goes up to hundred thousand times less than the main transceiver. That way, we impressively gain power and that, therefore, extends sensor nodes lifetime. Specific scenarios of WSNs such as On-demand or Event-Triggered applications are adequate candidates for WuRx. In this paper we introduce a nanowatt WuRx and we evaluate its performance when embedded into a WSn.","PeriodicalId":168063,"journal":{"name":"2014 IEEE 11th International Multi-Conference on Systems, Signals & Devices (SSD14)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125641387","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}
