Exploring Parallel I/O Concurrency with Speculative Prefetching

Parallel applications can benefit greatly from massive computational capability, but their performance usually suffers due to large latency in I/O accesses. Conventional I/O prefetching techniques are conservative and are limited by low accuracy and coverage. As the processor performance has been increasing rapidly and the computing power is virtually free, we introduce a novel speculative approach for comprehensive and aggressive parallel I/O prefetching in this study. We present the design of our approach as well as challenges, solutions, and our prototype implementation. The experiments have shown promising results in reducing I/O access latency.
Remarks on parameter selection for Server-aided Secret RSA computation schemes

In 1994 Burns and Mitchell reviewed the security and complexity of two types of schemes of Server-aided Secret Computation (SASC) protocols for RSA and gave a practical guidance for selecting parameters on the design of SASC protocols. In this Remark, we propose an active attack to show that some criterion of selecting parameters shall be added on to Burns and Mitchell's guidance to satisfy the security level as expected.
Calculate Golf Swing Trajectories from IMU Sensing Data

In the process of sport learning, learners spend a lot of time on practicing in order to develop correct action habit. Take golf practice as an example. Without the supervising of coaches, novices may keep practicing wrong swing actions, and that will cost more time later on to correct the wrong habit. It would be helpful to let learners can be aware of incorrect swing actions in self-training. In this work, we propose an IMU-based solution to help learners by allowing them to review their swing trajectories and also learn key features of the swings. In the proposed system, an IMU composed of an accelerometer, a magnetometer and a gyroscope is installed on the golf club to collect inertial motion data. From the collected data, swing trajectories can be calculated and swing features can also be extracted.
Stereo match based on linear feature

Techniques of image matching for stereo vision, generated with the aid of a structured light projector, are described, and are used to match primitives. Based on the description function of the primitive, the match rule is designed and four match constraints are used for eliminating the false match. A global to local control strategy is designed to accelerate the match process. This technique is used to obtain 3D measurements of human body, and to establish the surface representation for a computer-aided garment-design system. The results obtained indicate that this technique could also be used to acquire the 3D information for industrial parts and natural objects with smooth surfaces. <<ETX>>
A Qualitative Study of Orthognathic Patients’ Perceptions of Referral to a Mental Health Professional: Part 1—Questionnaire Development

Objectives The aim of this study was to develop a measure to assess orthognathic patients’ perceptions of referral to a mental health professional. Design Prospective qualitative study. Setting UCLH Foundation Trust. Subjects and methods The study was divided into two parts. The first phase involved developing a patient-centred questionnaire by carrying out semi-structured interviews with 10 orthognathic patients and 10 clinicians involved in orthognathic treatment provision. The transcripts from these interviews were then analysed using the N6© software package for qualitative research and thematic content analysis was carried out. As key themes and theories of patients’ perceptions of referral to a mental health professional began to emerge from the data, this directed the source of further interviews, allowing exploration and validation of all theories. When new themes ceased to arise, it was assumed that data saturation was reached, and no further interviews were undertaken. A questionnaire was then developed using the key themes from the interviews and this was piloted. Results Analysis of the interviews revealed that patient views could be divided into two main themes: service provision and perceptions of mental health professionals. These themes were incorporated into a questionnaire. Conclusions A new measure of patients’ perceptions of referral to a mental health professional is presented.

The imager is demonstrated operating as a global shutter (GS) oversampled binary image sensor reading out at 5.14kFPS. Frames are accumulated in real time on FPGA to construct a 256 photon/8bit output image at 20FPS.
Registration and integration of multiple range images for 3-D model construction

Registration and integration of measured data of real objects are becoming important in 3D modeling for computer graphics and computer-aided design. We propose a new algorithm of registration and integration of multiple range images for producing a geometric object surface model. The registration algorithm determines a set of rigid motion parameters that register a range image to a given mesh-based geometric model. The algorithm is an integration of the iterative closest point algorithm with the least median of squares estimator. After registration, points in the input range are classified into inliers and outliers according to registration errors between each data point and the model. The outliers are appended to the surface model to be used by registration with the following range images. The parts classified as inlier by at least one registration result is segmented out to be integrated. This process consisting of registration and integration is iterated until all views are integrated. We successfully experimented with the proposed method on real range image sequences taken by a rangefinder. The method does not need any preliminary processes.
A multiscale algorithm for closed contour matching in image sequence

An algorithm for closed deformable active contours, so called snakes, is described and applied to speckle images. Using polar coordinates, a snake sequence is represented by a scalar function (radial distance) of two variables (angle and time). The cost function to be minimized includes terms for spatial and temporal smoothness and for image forces. The latter terms make the contour attracted to bright structures and spatio-temporal edges. The snake search is carried out on a coarse-to-fine basis and relies on dynamic programming. The temporal smoothness is imposed on the entire image sequence simultaneously rather than sequentially. The method is edge orientation selective so that the snake is attracted only to positive edges in the direction of the normal to it curvature. The performance of the algorithm is investigated by sequences of simulated images and also echocardiographic images.

Flexural deformities in foals

Flexural deformities are a common condition of growing horses in which a joint is held in an abnormally flexed position. They affect soft tissue structures and occur in the sagittal plane, as opposed to angular limb deformities which primarily affect osseous structures and occur in the frontal plane, although periarticular soft tissue laxity can also cause angular limb deformities in newborn foals (Hunt 1998). Tendon laxities also occur commonly in newborn foals (for further information see box on Flexor tendon laxity later in this article). Flexural deformities are often referred to as ‘contracted tendons’, which implies a defect in the tendon itself and is incorrect in view of the proposed pathogeneses (see below); this term should consequently be avoided. Tendon contractions can occur as a result of scarring secondary to tendon injury; this is sometimes seen in mature horses but is rare in foals (Fackelman 1984).
New design on 2×VDD-tolerant power-rail ESD clamp circuit with low standby leakage in 65nm CMOS process

A 2×VDD-tolerant power-rail electrostatic discharge (ESD) clamp circuit with only thin gate oxide 1V devices and silicon-controlled rectifier (SCR) as main ESD clamp device has been proposed and verified in a 65nm CMOS process. The proposed power-rail ESD clamp circuit has an ultra-low standby leakage current by reducing the voltage drop across the gate oxide of the devices in the ESD detection circuit. From the measured results, the proposed design with SCR dimension of 50μm in width can achieve 6.5kV human-body-model (HBM), 300V machine-model (MM) ESD levels, and an ultra-low standby leakage current of 34.1nA at room temperature under the normal circuit operating condition with 1.8V bias.
Probabilistic interpage analysis for article extraction from document images

The progress of information processing and utilization technologies enables one to handle a huge information space. It is important to utilize the information stored in printed papers for constructing a huge information space. This paper presents an interpage analysis method for processing one issue of a journal and a magazine at one time. The method presented is based on the error correcting parsing technique which enables one to handle errors of recognition processes. The sequence of pages are parsed in two levels, the journal level and the logical component level, to extract logical components of journals and magazines.
Smart camera SoC system for interactive real-time real-brush based digital painting systems

Advanced digital paint systems, based on accurate simulation models for the paint, brush and canvas interaction enable a virtual painting environment familiar to artists, but also allow for new ways of expressivity. The new FluidPaint co-located real-brush-input & canvas-display systems put extremely high demands on the real-time image processing and the reaction time between brush strokes and the rendering of the painting result on the screen. A new Smart Camera System-on-Chip (SoC) architecture is presented enabling real-time input of brush-strokes with real brushes in the FluidPaint digital painting system.
The descriptive epidemiology of congenital and acquired cryptorchidism in a UK infant cohort

Introduction: Recent studies in other European countries suggest that the prevalence of congenital cryptorchidism continues to increase. This study aimed to explore the prevalence and natural history of congenital cryptorchidism in a UK centre. Methods: Between October 2001 and July 2008, 784 male infants were born in the prospective Cambridge Baby Growth Study. 742 infants were examined by trained research nurses at birth; testicular position was assessed using standard techniques. Follow-up assessments were completed at ages 3, 12, 18 and 24 months in 615, 462, 393 and 326 infants, respectively. Results: The prevalence of cryptorchidism at birth was 5.9% (95% CI 4.4% to 7.9%). Congenital cryptorchidism was associated with earlier gestational age (p<0.001), lower birth weight (p<0.001), birth length (p<0.001) and shorter penile length at birth (p<0.0001) compared with other infants, but normal size after age 3 months. The prevalence of cryptorchidism declined to 2.4% at 3 months, but unexpectedly rose again to 6.7% at 12 months as a result of new cases. The cumulative incidence of “acquired cryptorchidism” by age 24 months was 7.0% and these cases had shorter penile length during infancy than other infants (p = 0.003). Conclusions: The prevalence of congenital cryptorchidism was higher than earlier estimates in UK populations. Furthermore, this study for the first time describes acquired cryptorchidism or “ascending testis” as a common entity in male infants, which is possibly associated with reduced early postnatal androgen activity.
Improving the performance of the product fusion strategy

Among existing classifier combination rules the most widely used are sum, product and vote. Although product is more directly related to the compound class posterior probability, it does not perform well. Sum, which is derived under restricting assumptions, outperforms product, especially if the class aposteriori probability estimates are subject to high levels of noise. We establish the cause of product's degraded performance and propose a method to improve it. Tests on real and synthetic data demonstrate that the modified product has a number of advantages in relation to other rules that we experiment with.
Retrospective review of serological testing of potential human milk donors

Objective To estimate the prevalence of positive serology among potential donors to a human milk bank. Design Retrospective review of our experience with donor serological testing at our milk bank over a 6-year interval. Setting Not-for-profit, regional human milk bank. Patients Volunteer, unpaid potential donors of human milk. Interventions Serological testing for syphilis, HIV, hepatitis B, hepatitis C, human T cell lymphotropic virus type 1 (HTLV-1) and human T cell lymphotropic virus type 2 (HTLV-2). Main outcome measures Results of serological screening tests performed on potential donors. Results Of 1091 potential donors, 3.3% were positive on screening serology, including 6 syphilis, 17 hepatitis B, 3 hepatitis C, 6 HTLV and 4 HIV. Conclusions There is a significant incidence of positive serology among women interested in donating human milk. This implies that there may be significant risk associated with peer-to-peer distribution of human milk from unscreened donors.
Neonatal non-hemolytic hyperbilirubinemia: a prevalence study of adult neuropsychiatric disability and cognitive function in 463 male Danish conscripts

Objective To examine whether neonatal non-hemolytic hyperbilirubinemia is associated with adult neuropsychiatric disability and cognitive function. Methods The study included all men born as singletons ≥35 gestational weeks in two Danish counties from 1 January1977 to 31 December 1983 that registered at conscription in a Danish region. Their infant levels of hyperbilirubinemia was ascertained from hospital records. At conscription, the prevalence of neurologic conditions and performance on a standard group intelligence test (Boerge Prien test) was compared between men with and without neonatal non-hemolytic hyperbilirubinemia. Results The study group consisted of 463 conscripts exposed to neonatal non-hemolytic hyperbilirubinemia and 12 718 unexposed conscripts. The median value of maximum serum bilirubin concentration was 256 µmol/l (range 105–482). Among the exposed, 5.6% were deemed unfit for military service due to a neurologic or a psychiatric condition, compared with 4.8% among the unexposed (prevalence ratio 1.18, 95% CI 0.81 to 1.73). Among men with Boerge Prien measurement, mean Boerge Prien test score among 391 exposed men was 42.4 points compared with 43.4 points among 11 248 unexposed men (mean difference 1.0 points, 95% CI 0.0 to 1.9). There was no association between level of hyperbilirubinemia and cognitive score. Adjusted prevalence ratio of obtaining a Boerge Prien test score in the lowest quartile was 1.04 (95% CI 0.87 to 1.23). Conclusion The study found no evidence of an association between neonatal non-hemolytic hyperbilirubinemia and adult neurodevelopment and cognitive performance in male conscripts. Since cognitive performance was not associated with the severity of hyperbilirubinemia we ascribe the slightly lower cognitive scores among exposed to uncontrolled confounding.
Colour image texture analysis: dependence on colour spaces

In this paper we investigate the role of colour spaces on texture analysis. We extract a range of correlogram and colour moment features for the VisTex colour texture benchmark in different colour spaces and find the average probabilistic distance of separation across different objects for different features and suggest the colour spaces that are best suited for the classification process. We also show the results of k-nearest neighbour classification for different features and their combined set.
High-definition digital display case with the image-based interaction

This paper proposes a high-definition digital display case for manipulating a virtual exhibit that has linking mechanisms. This technique enhances the understanding of dynamic exhibits. It is difficult to construct interactive contents of dynamic virtual exhibits, because measuring the mechanism invokes the risk of an exhibit's deterioration, and it takes tremendous efforts to create a fine spun computer graphics (CG) model for mechanisms. Therefore, we propose an image-based interaction method that uses image-based rendering to construct interactive contents for dynamic virtual exhibits using the interpolation between exhibit pictures with a number of deformational conditions and viewpoints. Using this method, we construct a high-definition digital showcase and exhibit the interactive content at a museum to evaluate the availability of our system.
Segment-Based Stereo Matching Using Belief Propagation and a Self-Adapting Dissimilarity Measure

A novel stereo matching algorithm is proposed that utilizes color segmentation on the reference image and a self-adapting matching score that maximizes the number of reliable correspondences. The scene structure is modeled by a set of planar surface patches which are estimated using a new technique that is more robust to outliers. Instead of assigning a disparity value to each pixel, a disparity plane is assigned to each segment. The optimal disparity plane labeling is approximated by applying belief propagation. Experimental results using the Middlebury stereo test bed demonstrate the superior performance of the proposed method
Stereo Correspondence Using Stripe Adjacency Graph

This paper presents a new approach to solve the problem of stereo correspondence. In order to extract visible surfaces with similar texture from two different images, our method encodes input images to a series of so-called stripe adjacency graphs (SAG). A stripe is a connected region with only one segment on each scan-line and a SAG is a group of stripes with neighbourhood relationships. The algorithm retrieves surfaces from binocular images according to the matching degree between two sub-graphs in two images. The extracted surfaces are evaluated by the global matching cost that is defined as the sum of inter-stripe and intra-stripe energy. The experimental results show that our algorithm is a fast as well as an effective algorithm. It can give a dense disparity map
GQL, A Graphical Query Language for Semantic Databases

GQL is a formal query language for graphically manipulating a semantic database. The language provides a set of pattern images and a set of simple rules for constructing pattern graphs. Users describe their queries by drawing pattern graphs against the graphical schema of the database. This paper describes various aspects of GQL: the underlying model, the pattern images and graphs, and the representation of operations. Implementational issues of a GQL interpreter and its relation to other query languages are also discussed.
Estimating the location of illuminants in realist master paintings Computer image analysis addresses a debate in art history of the Baroque

We address the problem of estimating the position illuminants in realist master paintings. To this end, we apply an algorithm from computer vision that has been used to detect forgeries and composites in digital photographs. Our contributions are three-fold: 1) we introduce the application of a two-dimensional, model-free occluding contour algorithm to the problem of locating the source of illumination in realist master paintings, 2) we introduce a maximum-likelihood criterion and computational method for integrating estimates from multiple occluding contours, and 3) we apply our methods to a key painting adduced as evidence in a recent controversial theory about painting praxis in the Renaissance and Baroque
Facial Feature Tracking using a Multi-State Hierarchical Shape Model under Varying Face Pose and Facial Expression

This paper presents a multi-state hierarchical approach for facial feature tracking. A hierarchical formulation of statistical shape models is proposed to characterize both global shape constraints of human faces and local structural details of facial components. Gabor wavelets and gray level profiles are integrated for effective and efficient representation of feature points. Furthermore, multi-state local shape models are presented to deal with shape variations of facial components. Meanwhile, face pose estimation helps improve shape constraints for the feature search. Both facial component states and feature point positions are dynamically estimated using a multi-modal tracking approach. Experimental results demonstrate that the proposed method accurately and robustly tracks facial features under different facial expressions and pose variations
Self-Organisation in Games, Games on Self-Organisation

In this paper, we shed light on the phenomenon of self- organisation in the context of computer games. Self- organisation is an important concept that intersperses a broad range of real-world domains-from economy over ecology, the built infrastructure, distributed technologies to the life sciences. Yet, self-organisation is often hard to recognise and especially hard to control. Computer games can amend this problem by training players to cope with self-organising systems interactively. Here, they can continuously interact with self-organising systems, explore them without jeopardy and gain foundational insights in their dynamics. We present several examples of commercial titles that integrate aspects of self-organisation as well as several academically motivated games that explicitly build on top of it. We further propose a taxonomy on the use of self- organisation in gaming contexts and we conclude with an outlook on potential future works in this direction.
Changing and Learning in the Lives of Physicians

The purpose of continuing medical education is to encourage a change in the behavior of practitioners to enable them to keep pace with advances in medical science occurring since their formal training was completed. While there are many opinions and arguments as to whether traditional continuing medical education can productively change the practitioner's approach to problems, I know of no previous study that has attempted to analyze the multiple and complex reasons that seem to generate change. The authors of this book, all excellent contributors to the field of continuing education, have done just that. By a guided interview process, they have approached three questions: (1) What changes have you made or have occurred in your life or practice during the last year? (2) What caused this change to occur? and (3) Did you learn anything in order to make this change? For the purposes of the study the authors
