CAMERA CALIBRATION USING STRAIGHT LINES: ASSESSMENT OF A MODEL BASED ON PLANE EQUIVALENCE

The aim of this paper is to present the derivation and experimental assessment of a camera calibration method based on control straight lines. A mathematical model using straight lines was derived to consider both interior and exterior orientation parameters as unknown. The Interior Orientation Parameters to be estimated are the camera focal length, the coordinates of the principal point and the lens distortion coefficients. The mathematical model is based on the equivalence between the vector normal to the projection plane in the image space and the vector normal to the rotated projection plane in the object space. This model was implemented and tests with real data were performed. The results obtained with the proposed model were compared with those obtained with the calibration with bundle method and it is shown that the results are similar for both models.
T-S fuzzy control of IPMSM using backstepping integral sliding mode

This paper aims to design a robust controller for the Interior Permanent Magnet Synchronous Motor (IPMSM) based on the Takagi-Sugeno (T-S) fuzzy modeling, the sliding mode control(SMC) and the back-stepping control. The introduction of T-S fuzzy model is for the clearer description of nonlinear uncertainties and reduces computational burden, and the back-stepping technique for the considering of the load disturbance under the inevitable matching condition in the SMC. The Integral SMC is used for the problem of reaching phase.
A new direction for solving the consensus problem in networked systems

The consensus problem is an important topic in modern networked systems. The goal of the consensus protocol is to make each non-faulty processor agree on a common value without influence from faulty processors. However, if the initial-value proposed by the processor is shared by only a small number of other processors, this initial-value will not become the consensus value. In order to increase the chances that all processors agree on a consensus value they prefer and accept, we design a new consensus protocol that allows change of the initial-value within certain limitations during message exchange. This way, even if the final consensus value is not a value they have originally expected, it is still a value they prefer and accept.
PURD-TH-96-02 , OSU-TA-08 / 96 , hep-ph / 9603378 Classical decay of inflaton

We present the first fully non-linear calculation of inflaton decay. We map inflaton decay onto an equivalent classical problem and solve the latter numerically. In the λφ model, we find that parametric resonance develops slower and ends at smaller values of fluctuating fields, as compared to estimates existing in literature. We also observe a number of qualitatively new phenomena, including a stage of semiclassical thermalization, during which the decay of inflaton is essentially as effective as during the resonance stage.

Modeling and Optimization of Train Scheduling Network Based on Invulnerability Analysis

At present, the railway transport are always held up or even suspended because of the natural disasters occurred frequently. In order to guarantee the smooth operation of the railway transport and reduce the number of trains affected by the disasters as few as possible, proposal of train scheduling scheme with optimal invulnerability is proposed in this paper. Firstly, train scheduling network model is proposed based on present train scheduling scheme in China, in which the real railway station is described as a vertex, and the railway line is described as an edge, the number of trains on the railway lines is designed as the weight of edge. Secondly a new indicator of invulnerability measurement is proposed and regarded as the object function to be optimized by using improved particle swarm optimization algorithm. Finally comparison of invulnerability between the original scheme and optimal scheme with selective attack and random attack are analyzed and the simulation results show that the optimal train scheduling scheme have better invulnerability.
Dynamics of Feedback-Induced Packet Delay in ISP Router-Level Topologies

Internet behavior is becoming more complex due to everchanging networking technologies and applications. Thus, understanding and controlling the complex behavior of the Internet are important for designing future networks. One of the complex behaviors of the Internet is traffic dynamics. Previous studies revealed that flow control in the transport layer affects the tra ffic dynamics of the Internet. However, it is not clear how the topological structure impacts tra ffic dynamics. In this paper, we investigate packet delay dynamics and tra ffic fluctuation in ISP router-level topologies where the degree distribution exhibits a power-law nature, and the nodes interact via end-to-end feedback control functionality. We show the packet delay dynamics of the BA topologies generated by the Barab ásiAlbert (BA) model and the ISP router-level topologies. Simulation results show that the end-to-end delay distributions exhibit a heavy tail in the TCP model. Moreover, the number of links with highly fluctuating queue length increases dramatically compared to that in the stop-and-wait model. Even in this case, the high-modularity structures of the ISP topologies reduce the number of highly fluctuating links compared with the BA topologies. key words: Power-law degree distribution, ISP router-level topology, Traffic dynamics, TCP
Defining an Architecture DescriptionLanguage for Dassault Systèmes

Architecture Description Languages (ADL) are a major research theme in the software architecture community. Although many interesting proposals have been made, they don’t seem to influence the daily industrial practice. In this paper, we report on an attempt to define an ADL that fits the needs of a specific company: Dassault Systèmes. This company maintains and develops a large body of software with very short cycle times. Their relationship with partners and OEMs has led them to develop the Object Modeler: a component technology for open architecture (Sect. 2). We then give the major requirements on the ADL (Sect. 3), and briefly explain why existing ADLs are not satisfactory in this context (Sect. 4). We finally discuss our approach which takes advantage of the Object Modeler technology to ground the definition of our ADL (Sect. 5). We believe that this strategy for the definition of an ADL is not specific to Dassault Systèmes and the Object Modeler technology, and could be adapted to other component technologies like the Java beans or DCOM.
On the Design of a Trust Enhanced Distributed Authorisation Architecture for Service Oriented Architectures

Authorisation systems play a vital role in protecting access to resources in distributed systems. Traditionally, authorisation is performed at the user level to determine whether a user has the necessary privileges to access a requested resource. However, when it comes to the user's platform, it is often assumed that the system hosting the user and the software running on it are 'trusted' and that it will behave correctly. In this paper, we propose a comprehensive trust enhanced distributed authorisation architecture that provides a holistic framework for authorisation taking into account the state of a user platform. The model encompasses the notions of 'hard' and 'soft' trust to determine whether a platform can be trusted for authorisation. We first explain the rationale for the overall model and then describe our hybrid model with 'hard' and 'soft' trust components, followed by a description of the system architecture. We then illustrate proposed architecture in the context of a simple scenario involving a social networking system.
SESLA TRANSCRIBER: A SPEECH TRANSCRIPTION TOOL THAT ADAPTS TO YOUR SKILL AND TIME BUDGET

We present a speech transcription tool targeted at situations in which cost is a critical or limiting factor. This tool actively guides the transcription process by taking an automatically created transcript as a starting point, and asking for correction of only the parts likely to contain errors. The transcriber speciﬁes a time budget, and the software uses models of transcription accuracy and cost to choose which segments should be transcribed to achieve the highest error reduction. This approach has been found to be 25% more efﬁcient than cost-insensitive approaches in previous work. The cost model is adapted to the transcriber on-the-ﬂy during the transcription process, so no user enrollment is necessary. The segmentation is updated regularly to reﬂect improved cost models, and to recover from potential time prediction errors. The user interface was designed to be easy to learn and efﬁcient to use. It allows either transcribing each segment from scratch or post-editing, and has logging features that allow detailed user studies.
Insider Threat: Protecting the Enterprise from Sabotage, Spying, and Theft

The Secret Service, FBI, NSA, CERT (Computer Emergency Response Team) and George Washington University have all identified Insider Threats as one of the most significant challenges facing IT, security, law enforcement, and intelligence professionals today. This book will teach IT professional and law enforcement officials about the dangers posed by insiders to their IT infrastructure and how to mitigate these risks by designing and implementing secure IT systems as well as security and human resource policies. The book will begin by identifying the types of insiders who are most likely to pose a threat. Next, the reader will learn about the variety of tools and attacks used by insiders to commit their crimes including: encryption, steganography, and social engineering. The book will then specifically address the dangers faced by corporations and government agencies. Finally, the reader will learn how to design effective security systems to prevent insider attacks and how to investigate insider security breeches that do occur. Throughout the book, the authors will use their backgrounds in the CIA to analyze several, high-profile cases involving insider threats. * Tackles one of the most significant challenges facing IT, security, law enforcement, and intelligence professionals today* Both co-authors worked for several years at the CIA, and they use this experience to analyze several high-profile cases involving insider threat attacks * Despite the frequency and harm caused by insider attacks, there are no competing books on this topic.books on this topic
Lymphocytic Reaction to Colorectal Cancer Is Associated with Longer Survival, Independent of Lymph Node Count, Microsatellite Instability, and CpG Island Methylator Phenotype

Purpose: Host immune response to tumor may be an important prognostic factor for colon cancer patients. However, little is known on prognostic significance of histopathologic lymphoid reaction to tumor, independent of the number of lymph nodes examined and tumoral molecular alterations, including microsatellite instability (MSI) and the CpG island methylator phenotype (CIMP), both of which are associated with lymphocytic reaction and clinical outcome. Experimental Design: Using 843 colorectal cancer patients in two independent prospective cohorts, we examined patient prognosis in relation to four components of lymphocytic reaction (i.e., Crohn's-like reaction, peritumoral reaction, intratumoral periglandular reaction, and tumor-infiltrating lymphocytes) and overall lymphocytic score (0-12). CIMP was determined using eight markers including CACNA1G, CDKN2A (p16), CRABP1, IGF2, MLH1, NEUROG1, RUNX3, and SOCS1. Cox proportional hazard models computed hazard ratio for mortality, adjusted for covariates including tumor stage, body mass index, lymph node count, KRAS, BRAF, p53, cyclooxygenase-2 (PTGS2), MSI, CIMP, and LINE-1 methylation. Results: Increasing overall lymphocytic reaction score including tumor-infiltrating lymphocytes was associated with a significant improvement in colorectal cancer–specific and overall survival (log-rank P < 0.003). These findings remained significant (adjusted hazard ratio estimates, 0.49-0.71; Ptrend < 0.009) in multivariate models that adjusted for covariates, including body mass index, MSI, CIMP, LINE-1 hypomethylation, and cyclooxygenase-2. The beneficial effect of tumoral lymphocytic reaction was consistent across strata of clinical, pathologic, and molecular characteristics. Conclusions: Lymphocytic reactions to tumor were associated with improved prognosis among colorectal cancer patients, independent of lymph node count and other clinical, pathologic, and molecular characteristics.

Age‐related Changes in the Circadian and Homeostatic Regulation of Human Sleep

The reduction of electroencephalographic (EEG) slow‐wave activity (SWA) (EEG power density between 0.75–4.5 Hz) and spindle frequency activity, together with an increase in involuntary awakenings during sleep, represent the hallmarks of human sleep alterations with age. It has been assumed that this decrease in non‐rapid eye movement (NREM) sleep consolidation reflects an age‐related attenuation of the sleep homeostatic drive. To test this hypothesis, we measured sleep EEG characteristics (i.e., SWA, sleep spindles) in healthy older volunteers in response to high (sleep deprivation protocol) and low sleep pressure (nap protocol) conditions. Despite the fact that the older volunteers had impaired sleep consolidation and reduced SWA levels, their relative SWA response to both high and low sleep pressure conditions was similar to that of younger persons. Only in frontal brain regions did we find an age‐related diminished SWA response to high sleep pressure. On the other hand, we have clear evidence that the circadian regulation of sleep during the 40 h nap protocol was changed such that the circadian arousal signal in the evening was weaker in the older study participants. More sleep occurred during the wake maintenance zone, and subjective sleepiness ratings in the late afternoon and evening were higher than in younger participants. In addition, we found a diminished melatonin secretion and a reduced circadian modulation of REM sleep and spindle frequency—the latter was phase‐advanced relative to the circadian melatonin profile. Therefore, we favor the hypothesis that age‐related changes in sleep are due to weaker circadian regulation of sleep and wakefulness. Our data suggest that manipulations of the circadian timing system, rather than the sleep homeostat, may offer a potential strategy to alleviate age‐related decrements in sleep and daytime alertness levels.
Third dimension for measurement of multi user massive MIMO channels based on LTE advanced downlink

We characterize third-dimension (3D) of channel measurements based on two dimension channel model with fully-synchronize propagation of first time LTE-A multi-user centralized multiple-input, multiple-output(MU-MIMO) with sixteen transmitter antennas and three users. By exploiting the spatial correlation of signals originating from neighboring receiving antennas, there is a need for an accurate and actual radio propagation model around Shanghai Jiao Tong University (SJTU) campus network. The paper describes our real-time implementation and several test results are reported in the forthcoming LTE-A release. Measurements show the experimental characteristics of the sensitivity of the spatial correlation with the different array of polarization antennas between users that can be well approximated by a Kronecker production. In addition; we analyze the capacity of MU-MIMO systems to explain the achievable capacity rate of current LTE-A antenna configuration at the user side.
Mapping between Relational Databases and OwL Ontologies: an example

This paper shows how relational databases can be used to define a bridging mechanism between relational database and OWL ontology. We demonstrate on a simple yet completely elaborated example how mapping information stored in relational tables can be processed using SQL to generate RDF triples for OWL class and property instances. This technology provides the means to use relational database as a powerful tool to transform relational data to Semantic Web layer.
Dominant direction of natural textures using a modified Hough transform approach

The identification of a dominant direction in images of natural textures is a common problem, for example to assess the strength and quality for fibres in textiles or polymers in plastics. Although these are essentially made-up of linear structures the aim is to describe the distribution of directions rather than identifying individual lines. The Hough transform is a method for extracting features of a particular shape within an image. The original Hough transform is most commonly used for the detection of curves such as lines, curves, circles, etc. Here the Hough transform for line detection is considered. The Hough transform converts the problem of detecting a global feature in the image into a local problem in the Hough space. Good introductions can be found in Illingworth and Kittler (1988) and Leavers (1993). This paper considers a modified Hough transform based on the actual pixel intensities rather than the usual form in terms of counts from a thresholded image. The directional distribution is then obtained from the Hough transform. The principle modes of this distribution define the dominant directions, and the spread of the peaks in the distribution quantify the degree of dominance. Illustrative examples, using both simulated and real images, will be given covering a range of simple and complex structures.
Conflict Management : Managerial Approach towards Improving Organizational Performance

The focus of this paper is on managerial approach t o conflict management in an organization. The objectives of this study is to ascertain what c onstitute conflict, sources of conflict, views of conflict, consequences of conflict in an organiz tion and the strategies for dealing with organizational conflict etc. To effectively examine how conflict management will improve organizational performance, the study relies mainly on secondary data from textbook, internet, journals etc. The study reveals that conf lict is endemic in human life’s and cannot not totally be eradicated rather its effect can be mini ized so as to ensure that it does not hinder the activities of the organization by way of reduci ng performance. The paper recommends amongst others that managers at all levels should a cquaint themselves with potential causes of conflict in their organization and address them ear ly enough to forestall activities that will hamper the smooth running of the organization.
Certificateless strong key-insulated signature

To mitigate the damages of key-exposure, Dodis, Katz, Xu, and Yung [3], in Eurocrypt 2002, proposed a new paradigm called key-insulated security which provides tolerance against key exposures. Recently many identity-based key insulated signatures schemes have been proposed, however the problem of key escrow is inherent in this setting. To overcome this problem, certificateless public key cryptography was introduced in 2003 [1]. In this paper, we extend ID-based key-insulated signatures to certificateless scenarios and propose a certificateless key-insulated signature scheme with secure key-updates. The proposed scheme is strong key-insulated and perfectly key-insulated in the random oracle model.
A Transport Protocol for Multimedia Transmission in Overlay Networks

Overlay networks are opening up new ways for Internet usability, mainly by adding new services that are not available or cannot be implemented in the current Internet. Overlay networks use application level switches of intermediate nodes. However, the designs of overlay network are based on store-and-forward principles maintained by split TCP connections of hop-by-hop approaches and this can increase delay of packet delivery and cause unreliability of packet transmissions due to buffer overflow of the application level switch of each intermediate node, which has a limited buffer space. Also, hop-by-hop approaches for overlay networks cannot support end-to-end semantics. Thus, this study proposes a new Overlay Transport Protocol for overlay networks by considering management of end-to-end connection and congestion and flow control between source and destination nodes. By using a prototype implementation via simulation with MATLAB, We validate our analytical findings and evaluate the performance of proposed protocol which can provide end-to-end reliable data transfers, and also improve throughput in comparison with a network model where Overlay Transport Protocol layer is not available.
Iodine Intake and Thyroid Function in Pregnant Women in a Private Clinical Practice in Northwestern Sydney before Mandatory Fortification of Bread with Iodised Salt

Aim. The primary objective of the study was to assess the iodine nutritional status, and its effect on thyroid function, of pregnant women in a private obstetrical practice in Sydney. Methods. It was a cross-sectional study undertaken between November 2007 and March 2009. Blood samples were taken from 367 women at their first antenatal visit between 7 and 11 weeks gestation for measurement of thyroid stimulating hormone (TSH) and free thyroxine (FT4) levels and spot urine samples for urinary iodine excretion were taken at the same time as blood collection. Results. The median urinary iodine concentration (UIC) for all women was 81 μg/l (interquartile range 41–169 μg/l). 71.9% of the women exhibited a UIC of <150 μg/l. 26% of the women had a UIC <50 μg/l, and 12% had a UIC <20 μg/l. The only detectable influences on UIC were daily milk intake and pregnancy supplements. There was no statistically significant association between UIC and thyroid function and no evidence for an effect of iodine intake on thyroid function. Conclusions. There is a high prevalence of mild to moderate iodine deficiency in women in Western Sydney but no evidence for a significant adverse effect on thyroid function. The 6.5% prevalence of subclinical hypothyroidism is unlikely to be due to iodine deficiency.
Single-diode model and two-diode model of PV modules: A comparison

This paper proposes a comparison between single-diode model and two-diode model of photovoltaic (PV) module. The main concern of this work is the accuracy, number of unknown parameters, and the execution time for the unknown parameters, under standard test conditions (STC), in each model. The proposed work tests the accuracy of both models under different temperature conditions using two types of solar modules. The accuracy of each model is tested in terms of maximum power and maximum voltage, and compared to justify the pros and cons of each model.
Principal polarizations on products of elliptic curves

An abelian variety admits only a finite number of isomorphism classes of principal polarizations. The paper gives an interpretation of this number in terms of class numbers of definite Hermitian forms in the case of a product of elliptic curves without complex multiplication. In the case of a self-product of an elliptic curve, as well as in the two-dimensional case, classical class number computations can be applied to determine this number.
Robotics for small and medium enterprises : control and programming challenges Author ( s ) :

Robotics is one of those subjects that leaves nobody indifferent. No matter if they are used in industry or in our homes, mimic human capabilities, or are used to access dangerous environments, launched to space, or simply used to play with, robots are always a source of human interest and admiration. Here the focus is on robots used to work in industrial environments, i.e., robots built to substitute man in certain industrial manufacturing tasks; that is, being a mechatronic co-worker for humans.
