DC faults may cause severe disruptions in continuity of service to vital loads in a shipboard integrated power system, hence detection, isolation, and protection against such faults must be incorporated in both medium-voltage DC (MVDC) and low-voltage DC (LVDC) systems. Here we consider the effectiveness of existing z-source breakers and propose several new designs more appropriate for fault detection in MVDC and LVDC systems. In particular, we perform an optimization study that aims to minimize dissipation and weight and we identify the key parameters for use in MVDC and LVDC systems. Preliminary verification and validation studies are also included.

A variety of network deployments in disaster recovery, fire fighting and military scenarios create networks that do not form a connected network all the time. In such scenarios, paths between a source and destination may be created over time when nodes encounter each other due to node mobility. Many routing algorithms that can route messages in such delay-tolerant networking (DTN) settings have been proposed. Currently, these protocols do not differentiate between the messages that are being routed through the network treating all messages equally. But, there are DTN scenarios, in particular in military situations, where it is critical that messages are differentiated based on their importance to the task being supported. In this paper, we propose extensions to two popular DTN routing protocols, Epidemic and PROPHET, to implement such message prioritization. We implemented the proposed extensions in ONE (Opportunistic Network Emulator) and studied the performance of these extensions. Results from our simulation analysis demonstrate that it is possible to implement message prioritization in non-deterministic delay tolerant networks and provide us with insights into configuring message prioritization in DTN. In particular, the importance of selecting optimal queue lengths at each node to mitigate congestion in such networks. © 2012 IEEE.

Meaning-preserving Skolemization is essential for development of a correct and efficient method of solving query-answering problems. It requires global existential quantifications of function variables, which in turn require an extended space of logical formulas. This paper proposes a bottom-up procedure for computing a set of models that sufficiently represents the set of all models of a given clause set in the extended formula space. Instantiations of function variables often result in generation of infinitely many models. To overcome the difficulty, a model-making pattern is introduced for representing a possibly infinite number of models, and such a pattern is split as late as possible. The proposed procedure provides a method for solving query-answering problems that include unrestricted use of universal and existential quantifications. © 2012 Springer-Verlag.

As IT advances, warfare undergoing a paradigm shifts. It is going from a type that is weapon-based-making heavy use of conventional weapons-to one that is network-based, a type of warfare called network-centric warfare (NCW). In NCW, sharing of information can be guaranteed using communication technologies of the network. As the members that take part in missions can exchange and collaborate with other, they can be completed more successfully and efficiently, increasing the military might. Amid advancements being made in IT, the Korea military is also doing research for conducting more effective warfare, which it aims to do by connecting each of the entities together and sharing battlefield resources. This paper examines threats to information security in NCW, as well as requirements for information security. Furthermore, a development direction for information security is proposed. © 2012 Springer science+Business Media.

Although of the importance of analyzing vowel phonemes in the Modern Standard Arabic (MSA), it has not been paid a considerable attention in the published literature yet. Consequently, a formant-based analysis for the six vowels of MSA in connected speech was carried out in this work. The values of the first three formant frequencies were captured. The present results were compared to some previously published results conducted on MSA and other Arabic dialects. The comparison was performed from geometric perspective using the Euclidean distance. The results of the geometric comparison were found to be consistent with the visual inspection of the vowel triangles. © 2012 IEEE.

Symposium on Applications and the Internet (SAINT)

作者： Takuma Mori Ryuya Uda Masayuki Kikuchi Computer Science Program Tokyo University of Technology Hachioji Japan

Web services accounts have recently been automatically acquired in large quantities by bot-programs, which are malicious. Furthermore, the acquired accounts have been used for spamming, which is a problem for service operators or Internet users. Completely Automated Public Turing Tests To Tell computers and Humans Apart (CAPTCHAs) have generally been adopted for Web Services as a method of preventing Web services accounts from being acquired. These are Turing tests for users of Web services to distinguish between humans and bot-programs. There are several types of methods in CAPTCHAs, but the most typical in this field are text-based. However, these methods can be decoded with a high degree of probability, because of the OCR technology that has evolved. Much research on resolving this problem has been proposed. For example, one method in this research adds distortion to characters to make it difficult to analyze them with OCR. Despite this research, OCR has a higher success rate than humans. Thus, we propose a practical method for CAPTCHA in this paper in which only humans can provide correct answers by applying a modal completion.

this paper introduces a new approach for visualizing multidimentional weather-direction-related time-series data sets called "3D Spring Model". Spring Model is designed to visualize pattern behind large time-series weather data set and to clearify seasonal structure in the data. In addition, it supports visibility of seasonal shift and wind direction anomaly by direct comparison betweem successive spring cycles. The visualization contained three data types: (1) Weather parameter (such as windrun, temperature or rainfall etc.), (2) Wind directions and (3) time. We mapped the color to the model in such the way that it comply with human perception using color gradient. Level-Of-Detail scheme is applied and adjustable resulting different pattern time focus for users. Spring Model is highly self-contained for accumulative long term data. It is interactive, flexible and user-friendly. Spring Model is very well-suited to high computing power visualization environment. At the end of the paper, the observation of weather pattern in Nakhon Si Thammarat, Thailand using Spring Model was proposed as the case study to present the model vast applications. © 2012 IEEE.

Optical generation, templating, and polymerization of three-dimensional arrays of liquid-crystal defects decorated by plasmonic nanoparticles

Physical Review E 2013年第3期87卷 032503-032503页

作者： Julian S. Evans Paul J. Ackerman Dirk J. Broer Jao van de Lagemaat Ivan I.

Defects in liquid crystals are used to model topological entities ranging from Skyrmions in high-energy physics to early-universe cosmic strings, as well as find practical applications in self-assembly of diffraction gratings and in scaffolding of plasmonic nanoparticles, but they are hard to control and organize into three-dimensional lattices. We laterally scan focused laser beams to produce periodic arrays of twist-stabilized defects forming either linear (fingers) or axially symmetric (torons) configurations in partially polymerizable liquid crystal films. Polymerization allows for stabilization of these structures and the formation of three-dimensional arrays of defects by stacking of the thin cholesteric films on top of each other. In the process of fabrication of such arrays, we polymerize the liquid crystal film with an array of torons or fingers and then sequentially produce and photopolymerize new liquid crystal layers on top of it, thus obtaining a three-dimensional structure of twist-stabilized defects in a layer-by-layer fashion. Templating by the polymerized layer spontaneously yields ordered organization of fingers and torons in the new cholesteric layer, thus enabling a three-dimensional ordered structure of defects. Nondestructive three-dimensional imaging of director fields by use of three-photon excitation fluorescence polarizing microscopy reveals the nature of topological singularities and physical underpinnings behind the observed templating effect. Three-dimensional patterning of defects templates the self-assembly of plasmonic nanoparticles into individual singularities and their arrays, laying the groundwork for potential applications in nanophotonics, plasmonics, metamaterial fabrication, and nanoscale energy conversion.
