In this paper, starting from a real case of an art exhibit, we propose a mathematical model to simulate social network interactions of a visitor that shares his experience on a social network. The Integrate Fire (I F) model is used to reproduce the interest of spectators in a cultural heritage community. In our approach, visitor is modelled as a computational neuron, which is connected with his 'friends' by means of synapses (i.e., connections), representing friendships and/or common interests among them. The real data are of the exhibit are stored on a cloud system framework and representing the input of the proposed model.

It had been proved that the knowledge may promote more efficient evolution. Considering the knowledge defined in different form, we present multi-objective quantum-inspired cultural algorithms so as to effectively utilize the implicit information embodied in the evolution to promote more efficient search. The dual structure derived from cultural algorithm was adopted. In population space, the rectangle's height of each allele in quantum individuals was calculated in terms of non-dominated rank by sorting among individuals, instead of the relative fitness values. In belief space, the knowledge memorized the distribution and location about the non-dominated individuals' objective values in the objective space and directed the mutation and selection operations so as to influence the update of quantum individuals further. The statistical simulation results for five benchmark functions indicated that the proposed algorithm keeps the diversity of population better and obtains more uniform pareto-optimal solutions near the true pareto front.

Globally, safety technology of smart cars is developing for drivers' safety. Because the eye inspection of tire pressure is difficult, automatic sensing of the tire pressure is very important. Tire pressure monitoring system measures tires' pressure and temperature. By using TPMS system we can reduce pollution emissions, fuel consumption and car accident. U.S.A NHTSA made a law to use TPMS on cars. In this paper, two short frames are designed with unidirectional communication, which use minimum number of bits for low power operation. And the software of TPMS sensor module is designed such that the sensor mostly resides in deep sleep mode.

Online financial news is an important part of financial Big Data. In this paper, we propose a model to promptly recognize valuable news about senior executives' behavior and an online automatically trading strategy based on the model. Our model consists of three phases. First, word segmentation and keyword extraction are employed to quantify the financial text. For a better efficiency and promptness, manifold learning is utilized to reduce the dimension of keyword vector. Second, the idea of financial event study is utilized to judge whether a specific type of news could produce significantly positive or negative return. Third, support vector machine is employed to recognize the specific financial news and associate the quantified text with the stock return. Experiments show that the recognition work performed excellently and the behavior of increasing shareholdings produces significant positive return. Our online automatically trading strategy based on the model obtained a return of 55.62%, outperforming three main benchmarks in the same period, 4.52%, 12.47% and -6.89% respectively.

The aim of this work is to deposit nanocrystalline TiO 2 films by DC reactive facing-target sputtering (FTS) technique. The TiO 2 films have been deposited in Fluorine doped tin-oxide (FTO) glass substrate by FTS with sputtering pressure of 2.0 Pa, and Ar/O 2 gas ratio of 7:3. The main attraction of this paper is to correlate the structural, optical and morphological properties of these prepared TiO 2 film with variation of deposition time (like 2, 4 and 12 hrs). The thickness of TiO 2 film increases with the increase of deposition time. The correlation between the thickness variance and the structural, optical and morphological properties of TiO 2 thin films has been investigated in details. From the results, it is cleared that the crystallinity, grain size and surface roughness enhance but cluster size reduces with the increase of deposition time. These prepared films have chanced to apply directly for dye-sensitized solar cell, photoelectrochemical cell and water splitting applications.

High-power microwave (HPM) devices and systems have very important civilian and military applications. However, as the power density goes higher and higher, the HPM devices and systems are more and more vulnerable to the HPM breakdown, which becomes a critical limiting factor for the generation and transmission of the HPM radiation and the operation of HPM devices and systems. During HPM breakdown, the particle density and velocity in a HPM device can be modeled by plasma fluid equations with various ionization parameters, which would become highly nonlinear when the electromagnetic (EM) field intensity is sufficiently high (J. A. Bittencourt, Fundamentals of Plasma Physics. New York: Springer-Verlag, 2004).

초록보기원문보기 >

We study a multiple-input multiple-output (MIMO) model for radar and provide recovery guarantees for a compressive sensing approach. Several transmit antennas send random pulses over some time-period and the echo is recorded by several receive antennas. The radar scene is resolved on an azimuth-range-Doppler grid. Sparsity is a natural assumption in this context and we study recovery of the radar scene via l -minimization. On the one hand we provide an estimate for the well-known restricted isometry property (RIP) ensuring stable and robust recovery. Compared to standard estimates available for Gaussian random measurements we require more measurements in order to resolve a scene of certain sparsity. Nevertheless, we show that our RIP estimate is optimal up to possibly logarithmic factors. By turning to a nonuniform analysis for a fixed radar scene, we reveal that the fine-structure of the support set (not only its size) influences the recovery performance. By introducing a parameter measuring the well-behavedness of the support we derive a bound for the number of measurements sufficient for recovery that resembles the minimal one for Gaussian random measurements if this parameter is close to optimal, i.e., if the support set is not pathological. Our analysis complements earlier work due to Friedlander and Strohmer where the support set was assumed to be random.

Archaeological line drawings are archaeological contour, which can reflect the spatial information of cultural relics visually and intuitively. It is the foundation of the later repair and research work. But until now a large number of archaeological line drawing generation works still depend on the traditional manual style. To satisfy the needs of the line drawings generated works on archaeological excavations, computer is used to generate line drawings automatic, which improves cartographic efficiency and reduce the workload of the archeologists. But the existing contour line extraction algorithm such as traversal either based on edge or surface detection algorithm, although can quickly get the contour line of 3D models, cannot be directly used in cultural relic's area. The paper analyses the current algorithm on 3D model's contour detection area and the characteristic of cultural relics, composing a pre process forms a cultural relic line drawings generation algorithm based on explicit ridge line. This method first preprocesses the relic model, and then extracts its contour. When view change, it needn't extract again. It solves the line interrupted and visible problem in the process of contour drawing, and it has good performance in the relic work such as terracotta warriors' line drawings.

An identification control is a control of an object which mathematical model is unknown. For such objects initially the problem of identification is solved, and then for the resulting object model the problem of control synthesis is solved. As a result of control synthesis we obtain a multi-dimensional function that describes the dependence of control on the object state. After the implementation of this function in the control unit of the real object, it achieves the goal of control with optimal value of the quality criteria. To solve the identification and synthesis problems we use the method of network operator, which with the help of evolutionary algorithms finds the structure and parameters of the functions describing the model and functional dependence of control from the object state. In this paper, an example of using a network operator to solve the problem of identification control synthesis for a multilink robot is given.

The behavior of a magnetic gear which employs rare earth magnets is analyzed; the magnetic gear allows the power to be transmitted by transforming speed and torque. An analytical simplified approach for the analysis of the considered magnetic gear is used in this paper. The approach can be suitable for design aims. The mathematical model is one-dimensional: only the variation of electromagnetic quantities as function of angular position is considered, the permanent magnets are modeled by means of constant currents located at their edges. The resulting magnetomotive force generated by two rotors is modulated by the distribution of the variable permeance due to the difference of the magnetic permeability between the air of the slots and the magnetic material of the pole-pieces. The analytical results are verified by means of a finite element method.

Low delivery latency and high delivery ratio are two key goals in the design of routing schemes in Vehicular Ad Hoc Networks (VANETs). The existing routing schemes utilize real-time information (e.g., Geographical position and vehicle density) and historical information (e.g., Contacts of vehicles), which usually suffer from a long delivery latency and a low delivery ratio. Inspired by the unique features of bus systems such as wide coverage, fixed routes and regular service, we propose to use the bus systems as routing backbones of VANETs. In this work, we present a Community-based Bus System (CBS) which consists of two components: a community-based backbone and a routing scheme over the backbone. We collect real traces of 2515 buses in Beijing and build a community-based backbone by applying community detection techniques in the Beijing bus system. A two-level routing scheme is proposed to operate over the backbone. The proposed routing scheme performs sequentially in the inter-community level and the intra-community level, and is able to support message delivery to both mobile vehicles and specific locations/areas. Extensive experiments are conducted on the real trace data of the Beijing bus system and the results show that CBS can significantly lower the delivery latency and improve the delivery ratio. CBS is applicable to any bus-based VANETs.

Supply Chain Information Systems (SCIS) and their impact on organisational performance has been studied by a number of studies. This research seeks to extend this body of knowledge by adopting a fresh lens to explore empirically the relationship between organisational performance and SCIS in circumstances of economic downturn and financial turbulence. The statistical relationship between Supply Chain Information Systems (SCIS) #x201C;Effectiveness #x201D; and #x201C;Organisational Performance #x201D; is tested and measured by financial and non-financial variables. So, even though complexities associated with measuring SCIS efficiency and Organisational Performance continue to dominate research discussions, these are somewhat limited to just explaining the phenomenon without addressing the misalignment of the information provided by SCIS, business expectations and Organisational Performance. In consequence, this paper reports findings from a large survey of 168 SCIS managers in Greek SMEs where, even during economic downturn, a strong correlation between SCIS and non-financial Organisational Performance is evidenced. In considering the findings, this study proposes guidance to enhance SCIS Effectiveness and Organisational Performance.

Although wireless sensor networks are widely used in recent years, it remains a big security risk in the transmission of information and energy consumption of the nodes. By summarizing the existing wireless sensor networks attack measures, this paper proposes a way to attack wireless sensor networks by wireless injection, at different times fake nodes is disguised as acquisition nodes and transmission nodes, passing a lot of fake information to other nodes, and it results in the excessive energy consumption of the transmission nodes. In the component-based development Tiny OS system, we use the Micaz nodes to carry out the attack experiments and performance evaluation. Experiment results show that this method achieves the results. It is that the transmission delay will be significantly with more attack nodes and longer attack period, and it also verifies the insufficient performance of wireless sensor networks nodes.

Radio frequency identification (RFID) is a non-wired electromagnetic transmission to communicate between an end terminal and a chip-less tag with the principle of identification. Privacy protection and safety assurance are critical as RFID tags have an extensive range of conveyance with unauthorized scanning by malicious readers to broadcast data. Effectual confidentiality and security protocols should be exercised to safeguard the statistics in determining the exact radio waves. Characteristics of radio frequency wireless communication are accessible and the capabilities of the sensor nodes are adequate for providing protection and integrity. Analysis and exploration of the strategies on threats and countermeasures for wireless sensor network on access, retrieval and scalability of records are deliberated in this paper.

The distance learning system has an important role to play in development and expansion of education. Use of digital technology in education makes communication, interaction, storage, and distribution of educational content more efficient (AZAMBUJA, 2013). Today, technology and media are very diverse. Internet Protocol Television, IPTV, is a new vehicle for communication and interactive information that makes new distance learning ideas possible. IPTV has become fundamental because they are highly interactive, they deliver synchronous and asynchronous content at a high quality, and offer an expanding range of options to users. Cultural probe can lead to very promissing results as a qualitative IPTV research tool. It is a proposal of a conceptual model of a learning interface for IPTV. The objective of this article is to describe the development and application process and qualitative research results as a way to collect data using cultural probes to develop a proposal for an IPTV education interface to deliver synchrous and asynchronous content to teach engineering, specifically engineering distance learning via IPTV. Objective and tasks were designed in this study for engineering and communication students and electrical and telecommunication engineering teachers to record observations. The results obtained using this technique can help to develop a proposal for an educational interface that will enable IPTV to be used in distance education to teach engineering. The development and application process of the cultural probes in this article had three steps adapted from the method proposed by Mattelma #x0308;ki [1]: 1) tuning; 2) probe design; 3) interpretation and results. Finally, the main points of the experience were cast and discussed considering the results obtained and the protocol used to collect the data. The methodology encompasses: review of the literature to define the directives to be used in IPTV in distance education based on studies and considerations in the areas of engineering education, participative design, media, and learning; qualitative data were collected using cultural probes; a data analysis report; and a proposal for a conceptual model of an IPTV interface for use in distance education. The results indicate new challenges for qualitative research in the area.

The knowledge of the plasma state inside plasma elements permits a better simulation of the performance of the antenna with the aid of a commercial software. The result obtained demonstrated that it is not sufficient to consider a lossy dielectric to simulate a plasma reflector, and that a plasma model is necessary to design all the process involved in the radiation of the antenna.

With the rapid development of information society, intricate relationship between objects establish huge heterogeneous networks. The linkage is affected by multiple factors, which makes community detection on heterogeneous network a difficult task. Traditional clustering algorithms focus on divided factors, ignoring the combination of them. If the structure of multi-dimensional information is taken into consideration, the results can be more accurate and meaningful. In this paper, we introduce an improved fuzzy clustering algorithm to solve the problem of community detection of heterogeneous network. First extract the features of heterogeneous network and initialize K clusters. Then use a model to create a K-dimensional vector for each object which denotes the probability of belonging to every cluster. Through modifying a classic fuzzy clustering algorithm FCM (Fuzzy c-means) called HFCM, objects can be reassigned to cluster based on the maximum probability. Finally synthetic data and real data are used to verify the correctness of the algorithm.
