Frequency-Tunable Compact Antenna Using Quarter-Mode Substrate Integrated Waveguide

A frequency-tunable compact antenna based on quarter-mode substrate integrated waveguide (QMSIW) technology to reduce the size of the antenna is proposed. The resonant frequency of the antenna is electronically controlled by a dc bias voltage of a varactor loaded between the QMSIW and an additional parasitic patch on the top plane of the structure, with the bias network designed on the bottom plane. The performance of this antenna is demonstrated experimentally, with its resonant frequency varying from 2.28 to 2.50 GHz by increasing the dc bias voltage from 0 to 30 V.
Pattern Recognition Through PerceptuallyImportant Points In Financial Time Series

Technical Analysis is a financial risk management practice that has been in use since the advent of the stock market and Pattern Recognition is an indivisible part of it. There has been a lot of research into pattern recognition in time series. Existing pattern recognition techniques lack dynamic extensibility. They do not provide any interfaces in order to include new patterns for recognition dynamically. This limits the operability of these techniques to a particular domain. This research devises a new technique for domain independent pattern recognition while giving sufficient speed and accuracy. This enables it to be used by critical Decision Support Systems for time series of different domains. The system emulates the human visual cognition process by implementing the concept of Perceptually Important Points Identification (PIPI). Perceptually Important Points (PIP) represents the minimal set of data points which are necessary to form a pattern. For dynamic inclusion of patterns a Pattern Definition Language (PDL) has been conceptualized for defining patterns in time series by using a declarative programming paradigm. This also results in domain
Visual Denotations for Recognizing Textual Entailment

In the logic approach to Recognizing Textual Entailment, identifying phrase-to-phrase semantic relations is still an unsolved problem. Resources such as the Paraphrase Database offer limited coverage despite their large size whereas unsupervised distributional models of meaning often fail to recognize phrasal entailments. We propose to map phrases to their visual denotations and compare their meaning in terms of their images. We show that our approach is effective in the task of Recognizing Textual Entailment when combined with specific linguistic and logic features.
A Prospective Study of Aggression among Psychiatric Patients in Rehabilitation Wards

Objective: The aim of the study was to determine, among patients in rehabilitation wards, the prevalence and nature of aggressive behaviour and the relationship between aggressive behaviour and patient characteristics and ward factors. Method: The aggressive behaviour of all 220 inpatients within the rehabilitation program of a large psychiatric hospital in Victoria was assessed using the Staff Observation Aggression Scale. Results: Physical assaults occurred at a rate of 97.6 per 100 patients per year. About 40% of all incidents appeared to be unprovoked. Most physical incidents involved use of body parts and use of a weapon was uncommon. Aggression was most often directed at a staff member. Serious injury was rare. Aggressive behaviour was correlated with gender and duration of admission for the whole sample; however, there were different correlates of aggressive behaviour for different ward populations and different types of aggression. As for ward variables, time of day but not patient/staffing level was associated with aggressive behaviour. Conclusions: There was a high rate of aggressive behaviour among patients in rehabilitation wards; this should be taken into consideration in the planning of their community placement. The findings also caution against aggregating different ward populations and types of aggressive behaviour for research.
Uncertainty-based active ranking for document retrieval

One of the main problems in information retrieval is ranking documents according to their relevance to userspsila queries. Learning to rank is considered as a promising approach for addressing the issue. However, like many other supervised approaches, one of the main problems with learning to rank is the lack of labeled data, as well as labeling instances to create a rank model is time-consuming and costly. Thus, it is beneficial to minimize the number of labeled instances. In this paper, we bring the idea of active learning into ranking problem, and propose a new active ranking approach for document retrieval, referred to as Active RSVM. Specifically, we present an uncertainty- based query function to estimate the uncertainty of each instance, decide which instances can provide more information for the ranker and reduce the labeling cost. Experimental results on two real-world datasets show that our proposed active ranking algorithm can reduce the labeling cost greatly without decreasing the ranking accuracy.
Modelisation tridimensionnelle par elements finis destinee aux analyses de propagation d'ondes et de compatibilite electromagnetique

Cette these porte sur le developpement de modeles numeriques bases sur les elements finis pour les analyses de propagation d'ondes et de compatibilite electromagnetique. Elle concerne des modelisations tridimensionnelles dans les domaines frequentiel et temporel. Les formulations developpees sont basees sur la resolution de l'equation d'onde en termes du vecteur champ electrique. Les elements d'arete sont utilises pour l'interpolation du champ sur des maillages conformes composes de tetraedres. L'analyse de problemes a domaine ouverte est faite en utilisant la condition aux limites absorbante de silver-muller pour la troncature du volume de calcul. Dans la formulation temporelle, les derivees par rapport au temps sont discretisees avec la methode de newmark, qui permet d'obtenir un schema pas a pas dans le temps inconditionnellement stable et avec une precision d'ordre deux. Le memoire est compose de cinq chapitres. Le chapitre premier presente le probleme general de la propagation d'ondes ainsi que sa discretisation avec les elements finis d'arete. Dans le second chapitre, la methode est validee dans l'etude de la propagation d'une onde en milieux dielectriques classiques et en milieu plasma. Le rayonnement d'une petite antenne est aussi etudie. Le chapitre trois presente l'application de la formulation temporelle associee a des techniques de traitement du signal dans l'obtention des frequences propres de cavites resonnantes. Dans le chapitre quatre, les formulations frequentielle et temporelle sont appliquees et comparees dans l'analyse du couplage d'une onde incidente avec un fil conducteur place a l'interieur d'un boitier metallique possedant une ouverture. Des approximations sont faites de facon a restreindre le domaine de calcul au volume du boitier. Dans le chapitre cinq, qui traite aussi de problemes de couplage onde/structure, des formulations plus generales, utilisant des conditions absorbantes, sont proposees.
Graphene for Microwaves

Graphene nanoelectronics is an emerging area of research. The 2010 Nobel Prize for physics was awarded to A. Geim and K. Novoselov for the discovery of graphene and its unexpected physical properties, paving the way for many new applications in the area of nanoelectronics, nanooptics, and solid state physics. The most-studied microwave device is the graphene transistor, which, in only three years, has reached a cutoff frequency of 100 GHz. As consequence of this impressive development, the prediction that a 0.5-1 THz graphene FET transistor will soon be demonstrated is quite realistic. Moreover, graphene multipliers and other microwave graphene devices are expected to follow the graphene FET development dynamics and reach 100 GHz in few years.
A large dataset for the evaluation of ontology matching

Abstract Recently, the number of ontology matching techniques and systems has increased significantly. This makes the issue of their evaluation and comparison more severe. One of the challenges of the ontology matching evaluation is in building large-scale evaluation datasets. In fact, the number of possible correspondences between two ontologies grows quadratically with respect to the numbers of entities in these ontologies. This often makes the manual construction of the evaluation datasets demanding to the point of being infeasible for large-scale matching tasks. In this paper, we present an ontology matching evaluation dataset composed of thousands of matching tasks, called TaxME2. It was built semi-automatically out of the Google, Yahoo, and Looksmart web directories. We evaluated TaxME2 by exploiting the results of almost two-dozen of state-of-the-art ontology matching systems. The experiments indicate that the dataset possesses the desired key properties, namely it is error-free, incremental, discriminative, monotonic, and hard for the state-of-the-art ontology matching systems.
The Impact of Adopting Corporate Social Responsibility on Corporate Financial Performance: Evidence From Italian Listed Companies

This paper aims to analyse whether social rating can impact on financial performance of major Italian companies listed on the stock exchange and, subsequently, whether the Italian stock market has proved awareness of social and environmental issues.The study will highlight how companies included in the Italian FTSE MIB index have reacted to the Subprime Mortgage and Sovereign Debt crises, opting for socially responsible investments. The analysis describes the stock exchange trend of the FTSE MIB index companies, considering the ethical rating assigned to them by Standard Ethics on a yearly basis, over a period ranging from 2007 to 2013.The results of the Panel Data analysis conducted on the chosen sample seek to explain whether an ethical rating is a discriminating variable for an investor, analysing the existence of a significant relationship between socially responsible investments of a listed company and its stock market performance.
Transient Based Protection for HVDC Lines Using Wavelet-Multiresolution Signal Decomposition

This paper presents a new high-speed and credible protection technique for HVDC line. In the technique, wavelet-multiresolution signal decomposition technique is used to analyze the transient voltages generated by the faults. The technique can discriminate between faults inside the HVDC line and the outside ones reliably. Furthermore, an approach to distinguish lightning strokes from faults is also presented. Extensive simulations of CIGRE standard HVDC system and the actual CSG HVDC system prove the proposed techniques effective and reliable
Internal Governance Mechanisms and Operational Performance: Evidence from Index Mutual Funds

We provide new evidence linking board characteristics and performance. Using manually collected governance data from the mutual fund industry, we find an inverse relation between board size and fund performance. We also find evidence that organizational form plays an important role in determining operational performance. Overall, the results are consistent with the notion that there may not be a single optimal board structure that is applicable to all funds, that attempts to regulate board attributes should be considered with caution, and that sponsor-level factors are important board structure considerations.

High bandwidth of 8 GHz active quasi-circulator with integrated digital leakage canceler in SiGe BICMOS technology for automotive radar systems

An active quasi-circulator (QC) with high bandwidth is proposed for monostatic FMCW automotive 77-GHz radar sensors. The QC is build around a commonly used differential LNA. As the layout of the QC is symmetrical in contrast to traditionally active QCs, the system is robust and offers a high bandwidth in respect with transmit (TX) to receive (RX) signal isolation. A single ended to differential conversion is also provided by the proposed structure without any additional losses, which directly improves the noise figure (NF) performance of the receiver. Effects like process variations and antenna mismatch can be compensated by a digitally controlled CMOS based impedance tuner acting as a leakage canceler. The system has been fabricated in a 250-GHz fT Silicon-Germanium (SiGe) BiCMOS technology. The QC performance is demonstrated based on on-wafer measurements. Over a 10-GHz bandwidth, the receiver gain is higher than 7 dB, whereas the insertion loss of the passive TX-path is around 6.5 dB. Assuming an isolation of 30 dB, the bandwidth remains 8 GHz, which is sufficient for automotive radar systems.
A unified minimization framework for single/multi-shot nonparametric blind deblurring

The nonparametric blind deconvolution, either single or multi-shot, has been intensively studied since Fergus et al.'s variational Bayesian approach to camera shake deblurring [1]. However, in the current literature there is always a gap between the two highly related problems; single and multi-shot blind deconvolution are modeled and solved independently, lacking a unified optimization perspective. We attempt to bridge the gap between the two problems in this paper, via constructing a simple, rigorous and unified minimization functional which couples the variational Bayesian and maximum-a-posteriori principles. The new approach is depicted using a directed graphic model, in which the sharp image and the inverse noise variance associated with each shot are treated as random variables, while the blur-kernel, in difference from existing variational Bayesian methods, is just modeled as a deterministic parameter. With a universal, three-level hierarchical prior on the latent sharp image and a Gamma hyper-prior on each inverse noise variance, the single/multi-shot blind deconvolution is formulated into an ℓ0. 5-norm regularized negative log-marginal-likelihood minimization problem. By ideas of expectation-maximization, majorization-minimization, mean field approximation, and iteratively reweighted least squares, all the unknown quantities of interest, including the sharp image, the blur-kernel, the inverse noise variance, as well as other related parameters are estimated automatically. In comparison to existing single/multi-shot methods, the proposed method is not only more flexible, but also more adaptive while with less implementational heuristics. Experimental results on Levin et al.'s [2] benchmark data set demonstrate the effectiveness and superiority of the proposed framework.
Creating And Inhabiting A Space: Real-Time Algorithms And Performance Issues In Roger Reynolds's Angelspace (2008-2009)

The authors present the development and current performance practice of Roger Reynolds real-time interactive computer music composition AngelSpace (2008-2009). The essay first gives a broad introduction to the composition’s inspiration, materials, and form. The authors then describe the development and details of the spatialization and the other deterministic and probabilistic real-time algorithms utilized in each compositional section or “stage” of Angel Space. These descriptions also address performance strategies that the authors have discovered during experiments and rehearsals. The conclusion reflects on the aesthetic and technical directions suggested by the compositional approach explored in AngelSpace.
Cybersecurity Issues and Challenges: A view

The information and communications technology (ICT) industry has evolved greatly over the last half century. The technology is ubiquitous and increasingly integral to almost every facet of modern society. ICT devices and components are generally interdependent, and disruption of one may affect many others. Over the past several years, experts and policy makers have expressed increasing concerns about protecting ICT systems from cyberattacks, which many experts expect to increase in frequency and severity over the next several years. The act of protecting ICT systems and their contents has come to be known as cybersecurity. A broad and arguably somewhat fuzzy concept, cybersecurity can be a useful term but tends to defy precise definition. It is also sometimes inappropriately conflated with other concepts such as privacy, information sharing, intelligence gathering, and surveillance. However, cybersecurity can be an important tool in protecting privacy and preventing unauthorized surveillance, and information sharing and intelligence gathering can be useful tools for effecting cybersecurity. The management of risk to information systems is considered fundamental to effective cybersecurity. The risks associated with any attack depend on three factors: threats (who is attacking), vulnerabilities (how they are attacking), and impacts (what the attack does). Most cyberattacks have limited impacts, but a successful attack on some components of critical infrastructure (CI)—most of which is held by the private sector—could have significant effects on national security, the economy, and the livelihood and safety of individual citizens. Reducing such risks usually involves removing threat sources, addressing vulnerabilities, and lessening impacts. The government role in cybersecurity involves both securing government systems and assisting in protecting non- government systems. Under current law, all government department have cybersecurity responsibilities relating to their own systems, and many have sector-specific responsibilities for CI. On average, government departments spend more than 5% of their annual ICT budgets on cybersecurity. However, in the context of cybersecurity prevention it needs more attention to resolve difficult long-term challenges relating to design, incentives, consensus, and environment. In this paper the Management of Cybersecurity Risks, government role and Long-Term Challenges are discussed.
The Costs of Corporate Tax Complexity

Does tax code complexity alter corporate behavior? We investigate this question by studying the decision to claim refunds for tax losses. In a sample of 1.2 million observations from the population of corporate tax returns, only 37 percent of eligible firms claim their refund. A simple cost-benefit analysis of the tax loss choice cannot explain low take-up, motivating an exploration of how complexity alters this calculation. Research designs exploiting tax preparer switches, deaths, and relocations show that sophisticated preparers increase claim rates for small firms. Imperfect take-up has implications for measuring marginal tax rates and for the design of fiscal policy. (JEL D22, D61, E62, H25, K34)
Toolkits for automatic web service and GUI generation: KWATT

In a previous paper, we explained how to translate an input script into a functional web service, independent of the script language. We extend this work by considering the automatic creation of graphical user interfaces to allow interaction between a user and the web service generated by KWATT. The key aspects of this work are three‐fold. First, comment lines inserted into the script provide hints to the interface generator regarding the interface widgets. Second, the structure of the GUI is encoded into an XML file, and third, a plugin architecture permits the interface to be the output in one of several languages. We present an example interface to illustrate the concepts. Copyright © 2009 John Wiley & Sons, Ltd.

AlGaN/GaN heterostructure field effect transistors (HFETs) were fabricated with and without source field plates (SFP) on high resistivity Si (111) substrates. A single chip GaN HFET with a SFP achieved a saturated output power (Psat) of 368W (10.2W/mm) with 70% maximum drain efficiency (ηmax) when operated under pulsed RF conditions and a drain bias of 60V.
Poor Capacity for Proliferation of Pancreatic β-Cells in Otsuka-Long-Evans-Tokushima Fatty Rat: A Model of Spontaneous NIDDM

Otsuka-Long-Evans-Tokushima Fatty (OLETF) rat, a genetic model of spontaneous development of NIDDM, exhibits hyperglycemic obesity with hyperinsulinemia and insulin resistance similar to that in humans. It is still unclear whether a defect in the β-cell proliferation per se is the primary pathogenetic event in OLETF rat. To determine whether it is, we used partially pancreatectomized rats as a model, with administration of phlorizin to control blood glucose level, to examine whether the capacity for proliferation of P-cells during hyperglycemia or normoglycemia differs between OLETF and their diabetes-resistant counterparts, Long-Evans-Tokushima-Otsuka (LETO) rats. We also examined whether such a defect, if present, could be improved by nicotinamide. Male rats, 6 weeks of age, were allocated at random'to two groups: 70% pancreatectomy (Px) and sham-pancreatectomy (sham). Each group was divided into four subgroups by date of killing after surgery: 3-day, 7-day, 28-day (treated with phlorizin, nicotinamide, or saline), and 91-day. A sustained hyperglycemia was evident in the Px OLETF rats after surgery, which was associated with insufficient proliferation of β-cells, characterized by decrease in β-cell labeling index in proportion to decrease in β-cell mass and reduction in insulin content in the remnant pancreas. This defect was unaffected by restoration of normoglycemia induced by phlorizin injection. Administration of nicotinamide, however, ameliorated the sustained hyperglycemia by increasing (J-ceU proliferation. These findings suggest that OLETF rats have poor capacity for proliferation of pancreatic β-cells and that this change may be the critical pathogenetic event before the onset of overt diabetes.
