In ML detection, a proper Probability Distribution Function (PDF) such as the Generalized Gaussian Distribution (GGD) is usually required to model the statistical characteristics of the transform coefficients of the watermarked images. However in some cases, the GGD is not the most suitable model due to its limitation in modeling the pulse-shape distribution. In this paper, we propose a novel ML detection scheme. By performing ML detection in the absolute domain, we utilize the Weibull distribution, a special case of the Generalized Gamma distribution, to model the absolute transform coefficients. The experimental results demonstrate that the proposed detection scheme outperforms the conventional ones in both DWT and CT domain for natural images. Furthermore it improves the watermark detection rates averagely by 75.03% for Computer Graphic (CG) images compared with the conventional algorithm.","PeriodicalId":270495,"journal":{"name":"2014 IEEE REGION 10 SYMPOSIUM","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126923987","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 enables the identification of materials by decomposing the total attenuation of the material into the various physical contributions for each voxel. Spectral micro-CT equipped with energy-resolved photon counting detector has the ability to measure the spectrum of x-ray beams. It is known that the attenuation of x-ray photons is energy-dependent and each substance has a specific attenuation curve. Therefore, measurement of the specific attenuation responses can enable material differentiation. The goal of this study was to demonstrate the potential of the MARS-CT scanner for preclinical evaluation of biomarker particularly in ex vivo advanced atherosclerotic plaque. It was proposed that spectral CT has the potential to identify the presence of specific markers for vulnerable plaques: iron deposits and lipid core. Using spectroscopic methods developed with this system, it was possible to distinguish the presence of iron deposits and lipid core within ex vivo atherosclerotic plaques. Vulnerable plaques are unstable, prone to rupture and put the person at risk of cardiovascular events and strokes. This preclinical study is a precursor to the development of a clinical technique that will enable vulnerable atherosclerotic plaques to be identified in vivo prior to treatment or removal.","PeriodicalId":270495,"journal":{"name":"2014 IEEE REGION 10 SYMPOSIUM","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130318500","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 performance of the sensors were weighed against such criteria as precision, sampling frequency, invasiveness and the scalability of the sensor to smaller Micro Air Vehicle systems. The IR displacement sensor and IR camera tracking system were ruled out as potential sensors. The IR displacement sensor had a precision of 1mm making it too imprecise. The IR camera tracking system had a limited sampling frequency of 22Hz. In addition, both these concepts were not scalable to MAV sizes due to their complexity. The flex sensor is suitable as a position sensor due to its high precision of 0.25mm. It is an analogue sensor and has a sampling frequency only limited by the data-logger and frequency response. Frequency and thermal characteristics were acceptable. Additionally, its solid state nature makes it highly scalable.","PeriodicalId":270495,"journal":{"name":"2014 IEEE REGION 10 SYMPOSIUM","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128908506","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}

Advertisement videos play a major role in improving targeted sales of a product. The popularity of the advertisement depends on the number of viewers attracted to that advertisement video in a short span of time. Popular advertisements have more impact on the sales of the product. In this paper, we propose a new measure called Video Differential Index(VDI) to analyze and classify advertisement videos to know whether that video attracts more number of viewers or not. By using VDI measure we can also predict the type of video i.e., action-oriented, theme or concept based without watching the content of the video. Our experimental results demonstrated that, action oriented videos have high Video Differential Index as compared to theme or concept based videos. The VDI can be directly related to the popularity of the video.","PeriodicalId":270495,"journal":{"name":"2014 IEEE REGION 10 SYMPOSIUM","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123990660","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}

More explicitly, the performances of the Code Division Multiple Access CDMA cooperative schemes with two and eight users, employing systematic convolutional code (CC) are presented. The single relay cooperative network with decode-and-forward (DAF) relay is investigated in the proposed system. The proposed CDMA cooperative scheme is capable of attaining over 2 dB of SNR gain at a Bit Error Rate (BER) of 10-4 in comparison with the non cooperative scheme. The result shows at BER of 10-4 the system that employs the Maximum Ratio Combiner (MRC) outperformance the system that employs Equal Gain Combiner (EGC) by about 1.5 dB in terms of SNR. On the other hand, the signal power in cooperative system employing EGC varied from 5 to -20 dB. However, in non cooperative system the signal power varied from -10 to -30 dB. Which approve, those independent copies of the signal received by the receiver lead to mitigate the effect of fading.","PeriodicalId":270495,"journal":{"name":"2014 IEEE REGION 10 SYMPOSIUM","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129330878","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 proposed method uses reactive power load as control variable and reactive power supply as state variable. The method can effectively reduce active power loss of transmission lines, and it is easy to realize.
