All-optical implementations of OCDMA are often considered to be too complex to implement especially for cost-sensitive applications. On the other hand, electronic realization of OCDMA encoders/decoders are more cost effective but its throughput is restricted by the electronic processing bottleneck. In this paper, we propose an electronic implementation of OCDMA transceivers that takes advantage of newly emerging high-speed FPGA transceiver technologies, which offer speeds of up to 28 Gb/s. Though the chip rate of the proposed OCDMA system can approach such high speeds, the encoder/decoder processing can operate at much lower speed thanks to the parallel architecture that allows chips to be processed simultaneously. The proposed design benefits from its low resource utilization, which makes it suitable for smaller, affordable FPGA devices. This is in addition to the reconfigurability of FPGA devices, which further reduce the overall system cost.","PeriodicalId":297826,"journal":{"name":"2014 11th Annual High Capacity Optical Networks and Emerging/Enabling Technologies (Photonics for Energy)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124998601","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}

Its disastrous result is expected to be mitigated in the scope of smart gird, in which communication enabled smart devices exchange critical information to preclude such events. To carry the concept into reality, one pivotal step is quantitative study of the benefit smart grid can bring, i.e., to what extent smart grid can improve power system stability, specifically, in combating cascading failure? We identify three aspects, time, space, and scale, which are needed for thorough evaluation of the impact of a cascading failure, and further propose a new cascading failure model which is able to depict all three aspects with numerical results. Our observations explicitly suggest that communication between power devices is essential in alleviating the impact of cascading failure, and that even a basic information exchange among limited number of power devices could significantly ameliorate the aftermath of a cascading failure in power grid.","PeriodicalId":297826,"journal":{"name":"2014 11th Annual High Capacity Optical Networks and Emerging/Enabling Technologies (Photonics for Energy)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122660367","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}

VANETs will enable in the near future applications that will dramatically improve roadway safety and traffic efficiency. There is a need to increase traffic efficiency as the gap between the traveled and the physical lane miles keep increasing. The Dynamic Traffic Assignment problem (DTA) tries to dynamically distribute vehicles efficiently on the road network and in accordance with their origins and destinations. VANET environments will constitute the communication backbone that will enable DTA applications. Simulations play an important role in evaluating approaches to these applications as physical test beds are difficult to implement and cost prohibitive. We present extensions to Vehicles in Network Simulation (Veins), a hybrid simulator that incorporates the widely used Simulation of Urban Mobility (SUMO) and the renowned discrete event simulation environment OMNET++. These extensions allow for easy traffic assignment on Veins under program control by using information from broadcasted messages. We propose and simulate algorithm for DTA in VANETs. To demonstrate traffic improvements we use the algorithm in the presence of accidents.","PeriodicalId":297826,"journal":{"name":"2014 11th Annual High Capacity Optical Networks and Emerging/Enabling Technologies (Photonics for Energy)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117081011","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}

Normative judgments are often difficult to determine the limits to dispersion and free-flow of information by state and society. Filtering unethical website content requires keyword analysis, a challenge in current manual IP filtering technologies. Due to sparse representation of objectionable words in online content, the seed sets need to focus on positive norms in order to segregate norm violations. In this research work, we exploit these polarities in norm semantics to solve the problem of ethical filtering. We scan text for belief-conforming ethical norms, and filter out words that fall below the norm threshold. Using the Noahide Norms mapped to seven colors and conforming scores, we visualize normative tag cloud. The objective of our positively oriented normative tag cloud is to conform and filter raw text according to the ethical dimensions. Our method has a high classification accuracy compared to manual gold standard. Hence, it can accurately summarize and illustrate visual comparison and contrast of cultural norms out of plain English text.","PeriodicalId":297826,"journal":{"name":"2014 11th Annual High Capacity Optical Networks and Emerging/Enabling Technologies (Photonics for Energy)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117152983","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 burst mode of transmission, the timing synchronization includes the recovery of time varying sampling clock offset and the detection of start of burst. Both these operations are very important in wideband networking radio operation as they directly affect the Medium Access adaptive time slot algorithm. The proposed burst detection scheme computes the decision metric on the basis of a specially designed training sequence. The threshold value for the proposed burst detection metric is very less dependent on channel conditions. It is shown that both the proposed algorithms achieve better performance as compared to existing algorithms. Computationally efficient prototype hardware implementation on Field Programmable Gate Array (FPGA) is also presented.

In spite of the real success, this has its limitation because women needs to get exposed to ionizing radiation and many women in the eastern world would not like to be subjected to such breast exposure due to cultural inhibitions. In addition, the sensitivity is not more than 75%. In this context, research in optical biopsy is in the forefront since it is minimally invasive and done with non ionizing radiation. The laser beam could be launched through a hair thin fiber and the scattered radiation obtained from the sample could give spatially resolved information about the biochemical nature of the breast cancer sample. What is more important, the optical biopsy could be done based on spectral analysis of blood plasma itself so that in the long run a large segment of prospective women even in the rural areas can be screened just by blood analyses. The objective of our research is to evolve one such protocol and the first step is the spectral characterization of in vitro optical analyses of breast cancer samples. This is only the proof of the concept from a limited number of samples.","PeriodicalId":297826,"journal":{"name":"2014 11th Annual High Capacity Optical Networks and Emerging/Enabling Technologies (Photonics for Energy)","volume":"184 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116425774","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}
