  9. Query-adaptive multiple instance learning for video instance retrieval.

    Science.gov (United States)

    Ting-Chu Lin; Min-Chun Yang; Chia-Yin Tsai; Wang, Yu-Chiang Frank

    2015-04-01

    Given a query image containing the object of interest (OOI), we propose a novel learning framework for retrieving relevant frames from the input video sequence. While techniques based on object matching have been applied to solve this task, their performance would be typically limited due to the lack of capabilities in handling variations in visual appearances of the OOI across video frames. Our proposed framework can be viewed as a weakly supervised approach, which only requires a small number of (randomly selected) relevant and irrelevant frames from the input video for performing satisfactory retrieval performance. By utilizing frame-level label information of such video frames together with the query image, we propose a novel query-adaptive multiple instance learning algorithm, which exploits the visual appearance information of the OOI from the query and that of the aforementioned video frames. As a result, the derived learning model would exhibit additional discriminating abilities while retrieving relevant instances. Experiments on two real-world video data sets would confirm the effectiveness and robustness of our proposed approach.

  20. Assessment of Waco, Texas FLIR videotape

    Science.gov (United States)

    Frankel, Donald S.

    2001-09-01

    The FLIR video recorded by the FBI on 19 April 1993, records the final assault on the Branch Davidian compound in Waco, Texas, and the fire in which some 80 members of the sect died. Attention has focused on a number of flashes recorded on the videotape. The author has examined the 1993 videotape and the recorded videotapes of the re-enactment conducted at Fort Hood, Texas on 19 March 2000. The following conclusions have been reached: 1) The flashes seen on the tape cannot be weapons muzzle flash. Their duration is far too long and their spatial extent is far too great. They are almost certainly the result of solar energy or heat energy form nearby vehicles reflected toward the FLIR by debris or puddles. 2) The FLIR video technology has a very low probability of detecting small arms muzzle flash. 3) As a consequence of 2) above, the absence of muzzle flash detection on the FLIR tape does not prove that no weapons were actually fired during the final assault. Indeed, there is ample evidence (not presented here) that the Davidians fired at the federal agents, but none of their muzzle flashes are detectable on the videotape.

  3. Dynamic Programming for Instance Annotation in Multi-Instance Multi-Label Learning.

    Science.gov (United States)

    Pham, Anh T; Raich, Raviv; Fern, Xiaoli Z

    2017-12-01

    Labeling data for classification requires significant human effort. To reduce labeling cost, instead of labeling every instance, a group of instances (bag) is labeled by a single bag label. Computer algorithms are then used to infer the label for each instance in a bag, a process referred to as instance annotation. This task is challenging due to the ambiguity regarding the instance labels. We propose a discriminative probabilistic model for the instance annotation problem and introduce an expectation maximization framework for inference, based on the maximum likelihood approach. For many probabilistic approaches, brute-force computation of the instance label posterior probability given its bag label is exponential in the number of instances in the bag. Our contribution is a dynamic programming method for computing the posterior that is linear in the number of instances. We evaluate our method using both benchmark and real world data sets, in the domain of bird song, image annotation, and activity recognition. In many cases, the proposed framework outperforms, sometimes significantly, the current state-of-the-art MIML learning methods, both in instance label prediction and bag label prediction.

  4. Salience Assignment for Multiple-Instance Regression

    2007-01-01

    We present a Multiple-Instance Learning (MIL) algorithm for determining the salience of each item in each bag with respect to the bag's real-valued label. We use an alternating-projections constrained optimization approach to simultaneously learn a regression model and estimate all salience values. We evaluate this algorithm on a significant real-world problem, crop yield modeling, and demonstrate that it provides more extensive, intuitive, and stable salience models than Primary-Instance Regression, which selects a single relevant item from each bag.

  9. Multiple-Instance Regression with Structured Data

    Science.gov (United States)

    Wagstaff, Kiri L.; Lane, Terran; Roper, Alex

    2008-01-01

    We present a multiple-instance regression algorithm that models internal bag structure to identify the items most relevant to the bag labels. Multiple-instance regression (MIR) operates on a set of bags with real-valued labels, each containing a set of unlabeled items, in which the relevance of each item to its bag label is unknown. The goal is to predict the labels of new bags from their contents. Unlike previous MIR methods, MI-ClusterRegress can operate on bags that are structured in that they contain items drawn from a number of distinct (but unknown) distributions. MI-ClusterRegress simultaneously learns a model of the bag's internal structure, the relevance of each item, and a regression model that accurately predicts labels for new bags. We evaluated this approach on the challenging MIR problem of crop yield prediction from remote sensing data. MI-ClusterRegress provided predictions that were more accurate than those obtained with non-multiple-instance approaches or MIR methods that do not model the bag structure.

  11. Waco investigation: analysis of FLIR videotapes

    Science.gov (United States)

    Klasen, Lena M.

    2001-09-01

    This paper presents some of the image processing techniques that were applied to seek an answer to the question whether agents of the Federal Bureau of Investigation (FBI) directed gunfired against the Branch Davidian complex in the tragic event that took place in Waco, Texas, U.S., 1993. The task for this investigation was to provide a scientific opinion that clarified the cause of the questioned events, or flashes, that can be seen on one of the surveillance videotapes. These flashes were by several experts, concluded to be evidence of gunfire. However, there were many reasons to question the correctness of that conclusion, such as the fact that some of the flashes appeared on a regular basis. The main hypothesis for this work was that the flashes instead were caused by specular solar reflections. The technical approach for this work was to analyze and compare the flashes appearance. By reconstructing the spatial and temporal position of the sensor, the complex and the sun, the geometrical properties was compared to the theoretical appearance of specular solar reflections. The result showed that the flashes seen on the FLIR videotape, were caused by solar or heat reflections from single or multiple objects. Consequently, they could not form evidence of gunfire. Further, the result highlights the importance of considering the characteristics of the imaging system within investigations that utilizes images as information source. This is due to the need of separating real data from other phenomena (such as solar reflections), distortions and artifacts in a correct manner.

    Science.gov (United States)

    Vincent-Hamelin, E; Sarmiento, J M; de la Puente, J M; Vicente, M

    1997-05-01

    The educational role of surgical video presentations should be optimized by linking surgical images to graphic evaluation of indications, techniques, and results. We describe a PC-based video production system for personal editing of surgical tapes, according to the objectives of each presentation. The hardware requirement is a personal computer (100 MHz processor, 1-Gb hard disk, 16 Mb RAM) with a PC-to-TV/video transfer card plugged into a slot. Computer-generated numerical data, texts, and graphics are transformed into analog signals displayed on TV/video. A Genlock interface (a special interface card) synchronizes digital and analog signals, to overlay surgical images to electronic illustrations. The presentation is stored as digital information or recorded on a tape. The proliferation of multimedia tools is leading us to adapt presentations to the objectives of lectures and to integrate conceptual analyses with dynamic image-based information. We describe a system that handles both digital and analog signals, production being recorded on a tape. Movies may be managed in a digital environment, with either an "on-line" or "off-line" approach. System requirements are high, but handling a single device optimizes editing without incurring such complexity that management becomes impractical to surgeons. Our experience suggests that computerized editing allows linking surgical scientific and didactic messages on a single communication medium, either a videotape or a CD-ROM.

  18. Some insights on hard quadratic assignment problem instances

    Science.gov (United States)

    Hussin, Mohamed Saifullah

    2017-11-01

    Since the formal introduction of metaheuristics, a huge number Quadratic Assignment Problem (QAP) instances have been introduced. Those instances however are loosely-structured, and therefore made it difficult to perform any systematic analysis. The QAPLIB for example, is a library that contains a huge number of QAP benchmark instances that consists of instances with different size and structure, but with a very limited availability for every instance type. This prevents researchers from performing organized study on those instances, such as parameter tuning and testing. In this paper, we will discuss several hard instances that have been introduced over the years, and algorithms that have been used for solving them.

  19. A critique of medicalisation: three instances.

    Science.gov (United States)

    Ryang, Sonia

    2017-12-01

    By briefly exploring three different examples where the existence of mental illness and developmental delay has been presumed, this paper sheds light on the way what Foucault calls the emergence of a regime of truth, i.e. where something that does not exist is made to exist through the construction of a system of truth around it. The first example concerns the direct marketing of pharmaceutical products to consumers in the US, the second the use of psychology in semi-post-Cold War Korea, and the third the persisting authority of psychology in the treatment of the developmentally delayed. While these instances are not innately connected, looking at these as part of the process by which the authoritative knowledge is established will help us understand, albeit partially, the mechanism by which mental illness penetrates our lives as truth, and how this regime of truth is supported by the authority of psychology, psychiatry and psychoanalysis, what Foucault calls the 'psy-function,' reinforcing the medicalisation of our lives.

    1999-01-01

    A study was designed to assess the effects of a standardized instructional videotape on training senior medical students to acceptable levels of reliability in performing several commonly used observer dependent outcome measures in patients with osteoarthritis (OA). During a single day, six third-year medical students independently examined six patients with OA in predetermined order using a Latin Square design, before and after viewing a standardized videotape demonstrating 13 examination techniques. Reliability coefficients were calculated based on variance components of the analysis of variance (ANOVA) table. Preslandardization reliability coefficients were goniometry were uniformly low. Following the intervention, all but four reliability coefficients were >/= 0.93. For many measures, high levels of interobserver agreement were noted prior to viewing the instructional videotape. This may represent the success of undergraduate clinical skills training programmes, or it may be the result of having reviewed an illustrated instructional text just prior to the initial patient examinations. The notable exception was knee goniometry. Despite apparent familiarity with the technique, prestandardization reliability coefficients were very low. However, following the intervention, all coefficients improved dramatically, two-thirds achieving very high levels. These data suggest that skills development in senior medical students is not uniform and that, while reliability is high for many, the assessment of knee range of movement can be improved by viewing an instructional videotape.

  5. Patch Based Multiple Instance Learning Algorithm for Object Tracking.

    Science.gov (United States)

    Wang, Zhenjie; Wang, Lijia; Zhang, Hua

    2017-01-01

    To deal with the problems of illumination changes or pose variations and serious partial occlusion, patch based multiple instance learning (P-MIL) algorithm is proposed. The algorithm divides an object into many blocks. Then, the online MIL algorithm is applied on each block for obtaining strong classifier. The algorithm takes account of both the average classification score and classification scores of all the blocks for detecting the object. In particular, compared with the whole object based MIL algorithm, the P-MIL algorithm detects the object according to the unoccluded patches when partial occlusion occurs. After detecting the object, the learning rates for updating weak classifiers' parameters are adaptively tuned. The classifier updating strategy avoids overupdating and underupdating the parameters. Finally, the proposed method is compared with other state-of-the-art algorithms on several classical videos. The experiment results illustrate that the proposed method performs well especially in case of illumination changes or pose variations and partial occlusion. Moreover, the algorithm realizes real-time object tracking.

    Existing methods for visual saliency based image retrieval typically aim at single instance image. However, without any prior knowledge, the content of single instance image is ambiguous and these methods cannot effectively reflect the object of interest. In this paper, we propose a novel image retrieval framework based on multi-instance saliency model. First, the feature saliency is computed based on global contrast, local contrast and sparsity, and the synthesize saliency map is obtained by using Multi-instance Learning (MIL) algorithm to dynamically weight the feature saliency. Then we employ a fuzzy region-growth algorithm on the synthesize saliency map to extract the saliency object. We finally extract color and texture feature as the retrieval feature and measure feature similarity by Euclidean distance. In the experiments, the proposed method can achieve higher multi-instance image retrieval accuracy than the other single instance image retrieval methods based on saliency model.

    posteriors. Given the instance labels, the label of a bag can be obtained as a classifier combining problem. An optimal decision rule is derived that determines the threshold on the fraction of instances in a bag that is assigned to the concept class. We provide estimators for the two parameters in the model...... with the assumption that instances are drawn from a mixture distribution of the concept and the non-concept, which leads to a convenient way to solve MIL as a classifier combining problem. It is shown that instances can be classified with any standard supervised classifier by re-weighting the classification...

    Constraint satisfaction problems are of special interest for the artificial intelligence and operations research community due to their many applications. Although heuristics involved in solving these problems have largely been studied in the past, little is known about the relation between instances and the respective performance of the heuristics used to solve them. This paper focuses on both the exploration of the instance space to identify relations between instances and good performing heuristics and how to use such relations to improve the search. Firstly, the document describes a methodology to explore the instance space of constraint satisfaction problems and evaluate the corresponding performance of six variable ordering heuristics for such instances in order to find regions on the instance space where some heuristics outperform the others. Analyzing such regions favors the understanding of how these heuristics work and contribute to their improvement. Secondly, we use the information gathered from the first stage to predict the most suitable heuristic to use according to the features of the instance currently being solved. This approach proved to be competitive when compared against the heuristics applied in isolation on both randomly generated and structured instances of constraint satisfaction problems.

  9. Multi-instance dictionary learning via multivariate performance measure optimization

    The multi-instance dictionary plays a critical role in multi-instance data representation. Meanwhile, different multi-instance learning applications are evaluated by specific multivariate performance measures. For example, multi-instance ranking reports the precision and recall. It is not difficult to see that to obtain different optimal performance measures, different dictionaries are needed. This observation motives us to learn performance-optimal dictionaries for this problem. In this paper, we propose a novel joint framework for learning the multi-instance dictionary and the classifier to optimize a given multivariate performance measure, such as the F1 score and precision at rank k. We propose to represent the bags as bag-level features via the bag-instance similarity, and learn a classifier in the bag-level feature space to optimize the given performance measure. We propose to minimize the upper bound of a multivariate loss corresponding to the performance measure, the complexity of the classifier, and the complexity of the dictionary, simultaneously, with regard to both the dictionary and the classifier parameters. In this way, the dictionary learning is regularized by the performance optimization, and a performance-optimal dictionary is obtained. We develop an iterative algorithm to solve this minimization problem efficiently using a cutting-plane algorithm and a coordinate descent method. Experiments on multi-instance benchmark data sets show its advantage over both traditional multi-instance learning and performance optimization methods.

    Full Text Available DOI: http://dx.doi.org/10.5007/1980-0037.2013v15n2p204 People from all age groups and social backgrounds have always sought to learn swimming. However, the swimming learning process is usually considered repetitive and tiring, requiring the teacher to use methods that motivate students to join the practice without ignoring the need for improvement in their performance. This study assessed motivation during a breaststroke learning process in students who received videotape feedback, verbal feedback, and who did not receive any feedback during practice. Thirty seven swimming inexperienced students were divided into three groups: Video (n=13, which received videotape feedback; Verbal (n=15, which received verbal feedback; and Control (n=9, which did not receive any feedback during experimental phases (pre-test, acquisition (5 days, post-test and retention. Participants completed a questionnaire based on Likert scale for motivation assessment. Scores were given to their performance by a swimming teacher to assess breaststroke learning during each experimental phase. Results of motivation assessment showed that students who received feedback (videotape or verbal felt more motivated during practice than those who did not receive any feedback. Regarding the breaststroke learning, all participants improved their performance along experimental phases, but, during the retention one, Verbal group’s performance was considered superior to the Control group’s performance. This study concluded that the use of videotape and verbal feedback has motivational results on breaststroke learning, and that it is effective in the learning process.

    Neistadt, M E; Smith, R E

    1997-05-01

    The purpose of this study was to examine the effect of a "classroom-as-clinic" format, using videotaped occupational therapy evaluations, on students' diagnostic reasoning skills. In the classroom-as-clinic format, students write a problem list on the basis of preliminary client information before viewing the videotape. A post-hoc experimental design was used to compare the accuracy of treatment plan problem lists for two groups of senior occupational therapy students--one group viewed two videotapes of client-therapist interactions without a classroom-as-clinic format (n = 82), and one group viewed the same videotapes within the context of a classroom-as-clinic format (n = 45). Both groups viewed the same two videotapes. Videotape 1 was of a client with a brain stem infarct, and Videotape 2 was of a client with traumatic brain injury. Subjects experiencing a classroom-as-clinic format identified significantly more occupational therapy problems for Videotape 1 than those who did not have preevaluation information. There was no significant difference between the two subject groups in the accuracy of their problem lists for Videotape 2. Only subjects in the non-classroom-as-clinic group showed a significant improvement from Videotape 1 to Videotape 2 in occupational therapy problem identification. This study suggests that to be truly effective when used videotapes, the classroom-as-clinic methodology needs to be combined with explicit coaching in problem sensing and problem definition.

    2015-01-01

    In his minor essay from 1914, Some Reflections on Schoolboy Psychology, Freud placed immense significance upon the father-son relationship as enabling or inhibiting the individual quest towards a mature, separate, and healthy development. In this essay, I will explore Freud's observations to illuminate the journey taken by Assaff, a 34-year old man who, during the early stages of his adolescence, had a father who was emotionally absent due a traumatic experience during his military service in the Israeli Defense Forces. Through transference work, the impact of the emotional absence will be shown. I will demonstrate how the boy was able unconsciously to use the music of Tommy, a rock opera by the British band The Who, as a transitional object. I will show how that piece of music provided Assaff with the sense of hope that helped during the darker times of his adolescent.

    2012-06-01

    We present a bundle algorithm for multiple-instance classification and ranking. These frameworks yield improved models on many problems possessing special structure. Multiple-instance loss functions are typically nonsmooth and nonconvex, and current algorithms convert these to smooth nonconvex optimization problems that are solved iteratively. Inspired by the latest linear-time subgradient-based methods for support vector machines, we optimize the objective directly using a nonconvex bundle method. Computational results show this method is linearly scalable, while not sacrificing generalization accuracy, permitting modeling on new and larger data sets in computational chemistry and other applications. This new implementation facilitates modeling with kernels.

    The Thermal and Electrical Conductivity Probe on NASA's Phoenix Mars Lander detected small and variable amounts of water in the Martian soil. In this schematic illustration, water molecules are represented in red and white; soil minerals are represented in green and blue. The water, neither liquid, vapor, nor solid, adheres in very thin films of molecules to the surfaces of soil minerals. The left half illustrates an interpretation of less water being adsorbed onto the soil-particle surface during a period when the tilt, or obliquity, of Mars' rotation axis is small, as it is in the present. The right half illustrates a thicker film of water during a time when the obliquity is greater, as it is during cycles on time scales of hundreds of thousands of years. As the humidity of the atmosphere increases, more water accumulates on mineral surfaces. Thicker films behave increasingly like liquid water. The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA's Jet Propulsion Laboratory, Pasadena, Calif. Spacecraft development is by Lockheed Martin Space Systems, Denver.

  11. Videotaped recording as a method of participant observation in psychiatric nursing research.

    2000-05-01

    This paper describes videotaped recording as a data collection method when conducting participant observation in a psychiatric nursing study. The videotaped episodes were part of the daily life of psychiatric nursing in a hospital environment. The advantages and limitations of using videotaped recording in nursing research will be discussed. This paper is based on two studies. The data consisted of 21 videotaped episodes of nursing report sessions or interdisciplinary team meetings in the psychiatric clinic of a university hospital. The participants consisted of patients, their significant others, nurses, doctors, social workers and physiotherapists. All videotaped material was transcribed verbatim. An essential advantage of videotaping is that most potentially useful interaction and behaviour can be captured. The advantage in terms of the credibility of videotaping was that the investigator was able to review the same videotaped situations again and again. Videotaped material is rich and provides several possibilities for analysing the data. In these studies data and source triangulation enabled the researchers to reduce personal influence on the results. The investigator must also be aware of the limitations concerning this method. The most essential limitations are mechanical problems and the influence of videotaping on behaviour. Careful ethical considerations are important concerning personal privacy, informed consent and respect for the self-determination of psychiatric patients.

We consider 7 different domain adaptation strategies and answer 7 research questions, which give us a recipe for domain adaptation in MT. We perform English to German statistical MT (SMT experiments in a setting where test and training sentences can come from different corpora and one of our goals is to learn the parameters of the sampling process. Domain adaptation with training instance selection can obtain 22% increase in target 2-gram recall and can gain up to 3:55 BLEU points compared with random selection. Domain adaptation with feature decay algorithm (FDA not only achieves the highest target 2-gram recall and BLEU performance but also perfectly learns the test sample distribution parameter with correlation 0:99. Moses SMT systems built with FDA selected 10K training sentences is able to obtain F1 results as good as the baselines that use up to 2M sentences. Moses SMT systems built with FDA selected 50K training sentences is able to obtain F1 point better results than the baselines.

  19. Instance Selection for Classifier Performance Estimation in Meta Learning

    Directory of Open Access Journals (Sweden)

    Marcin Blachnik

    2017-11-01

    Full Text Available Building an accurate prediction model is challenging and requires appropriate model selection. This process is very time consuming but can be accelerated with meta-learning–automatic model recommendation by estimating the performances of given prediction models without training them. Meta-learning utilizes metadata extracted from the dataset to effectively estimate the accuracy of the model in question. To achieve that goal, metadata descriptors must be gathered efficiently and must be informative to allow the precise estimation of prediction accuracy. In this paper, a new type of metadata descriptors is analyzed. These descriptors are based on the compression level obtained from the instance selection methods at the data-preprocessing stage. To verify their suitability, two types of experiments on real-world datasets have been conducted. In the first one, 11 instance selection methods were examined in order to validate the compression–accuracy relation for three classifiers: k-nearest neighbors (kNN, support vector machine (SVM, and random forest. From this analysis, two methods are recommended (instance-based learning type 2 (IB2, and edited nearest neighbor (ENN which are then compared with the state-of-the-art metaset descriptors. The obtained results confirm that the two suggested compression-based meta-features help to predict accuracy of the base model much more accurately than the state-of-the-art solution.

  20. Instance-based concept learning from multiclass DNA microarray data

    Directory of Open Access Journals (Sweden)

    Dubitzky Werner

    2006-02-01

    Full Text Available Abstract Background Various statistical and machine learning methods have been successfully applied to the classification of DNA microarray data. Simple instance-based classifiers such as nearest neighbor (NN approaches perform remarkably well in comparison to more complex models, and are currently experiencing a renaissance in the analysis of data sets from biology and biotechnology. While binary classification of microarray data has been extensively investigated, studies involving multiclass data are rare. The question remains open whether there exists a significant difference in performance between NN approaches and more complex multiclass methods. Comparative studies in this field commonly assess different models based on their classification accuracy only; however, this approach lacks the rigor needed to draw reliable conclusions and is inadequate for testing the null hypothesis of equal performance. Comparing novel classification models to existing approaches requires focusing on the significance of differences in performance. Results We investigated the performance of instance-based classifiers, including a NN classifier able to assign a degree of class membership to each sample. This model alleviates a major problem of conventional instance-based learners, namely the lack of confidence values for predictions. The model translates the distances to the nearest neighbors into 'confidence scores'; the higher the confidence score, the closer is the considered instance to a pre-defined class. We applied the models to three real gene expression data sets and compared them with state-of-the-art methods for classifying microarray data of multiple classes, assessing performance using a statistical significance test that took into account the data resampling strategy. Simple NN classifiers performed as well as, or significantly better than, their more intricate competitors. Conclusion Given its highly intuitive underlying principles – simplicity

    To compare the impact of a library of pulmonary rehabilitation videotapes versus an older videotape and usual care on quality of life and ability to perform activities of daily living in persons with chronic obstructive pulmonary disease. Two hundred fourteen patients diagnosed with chronic obstructive pulmonary disease, emphysema, or chronic bronchitis were recruited and randomized to receive customized videotapes, standard videotapes, or usual care. Outcome measures included the Fatigue Impact Scale, Seattle Obstructive Lung Disease Questionnaire, and the SF-36(R) Health Survey. Differences in coping skills and emotional functioning on the Seattle Obstructive Lung Disease Questionnaire were found among the 174 subjects who completed the study. The customized videotape group improved by 8.6 and 4.8 points, respectively, whereas the score of the other groups decreased by less than 1 point for the coping skills, and the scores of the standard video and the control groups decreased by 3.0 and 2.1 points, respectively, for emotional functioning (P Impact Scale also improved for the customized videotape group, whereas the scores of the others remained unchanged. Videotape users demonstrated better conversion to and retention of exercise habits, with over 80% of customized videotape subjects who reported exercise habits at baseline continuing the habits as compared with 40% in the usual care group. Sedentary subjects at baseline were more likely to begin and maintain exercise if randomized to videotapes. These findings demonstrate increased quality of life, lower fatigue, and better compliance with a prescribed exercise regimen among subjects using the customized videotapes. There was a significant improvement in emotional functioning and coping skills among customized videotape subjects.

    The purpose of our work is to mine streaming data from a variety of hundreds of automotive sensors in order to develop methods to minimize driver distraction from in-vehicle communications and entertainment systems such as audio/video devices, cellphones, PDAs, Fax, eMail, and other messaging devices. Our endeavor is to create a safer driving environment, by providing assistance in the form of warning, delaying, or re-routing, incoming signals if the assistance system detects that the driver is performing, or is about to perform, a critical maneuver, such as passing, changing lanes, making a turn, or during a sudden evasive maneuver. To accomplish this, our assistance system relies on maneuver detection by continuously evaluating various embedded vehicle sensors, such as speed, steering, acceleration, lane distance, and many others, combined into representing an instance of the "state" of the vehicle. One key issue is how to effectively and efficiently monitor many sensors with constant data streams. Data streams have their unique characteristics and may produce data that is not relevant or pertinent to a maneuver. We propose an adaptive sampling method that takes advantage of these unique characteristics and develop algorithms that attempt to select relevant and important instances to determine which sensors to monitor and how to provide quick and effective responses to this type of mission critical situations. This work can be extended to many similar sensor applications with data streams.

    Automatic image annotation is now a tough task in computer vision, the main sense of this tech is to deal with managing the massive image on the Internet and assisting intelligent retrieval. This paper designs a new image annotation model based on visual bag of words, using the low level features like color and texture information as well as mid-level feature as SIFT, and mixture the pic2pic, label2pic and label2label correlation to measure the correlation degree of labels and images. We aim to prune the specific features for each single label and formalize the annotation task as a learning process base on Positive-Negative Instances Learning. Experiments are performed using the Corel5K Dataset, and provide a quite promising result when comparing with other existing methods.

  10. Multiple instance learning tracking method with local sparse representation

    KAUST Repository

    Xie, Chengjun

    2013-10-01

    When objects undergo large pose change, illumination variation or partial occlusion, most existed visual tracking algorithms tend to drift away from targets and even fail in tracking them. To address this issue, in this study, the authors propose an online algorithm by combining multiple instance learning (MIL) and local sparse representation for tracking an object in a video system. The key idea in our method is to model the appearance of an object by local sparse codes that can be formed as training data for the MIL framework. First, local image patches of a target object are represented as sparse codes with an overcomplete dictionary, where the adaptive representation can be helpful in overcoming partial occlusion in object tracking. Then MIL learns the sparse codes by a classifier to discriminate the target from the background. Finally, results from the trained classifier are input into a particle filter framework to sequentially estimate the target state over time in visual tracking. In addition, to decrease the visual drift because of the accumulative errors when updating the dictionary and classifier, a two-step object tracking method combining a static MIL classifier with a dynamical MIL classifier is proposed. Experiments on some publicly available benchmarks of video sequences show that our proposed tracker is more robust and effective than others. © The Institution of Engineering and Technology 2013.

  11. Parallel multiple instance learning for extremely large histopathology image analysis.

    Histopathology images are critical for medical diagnosis, e.g., cancer and its treatment. A standard histopathology slice can be easily scanned at a high resolution of, say, 200,000×200,000 pixels. These high resolution images can make most existing imaging processing tools infeasible or less effective when operated on a single machine with limited memory, disk space and computing power. In this paper, we propose an algorithm tackling this new emerging "big data" problem utilizing parallel computing on High-Performance-Computing (HPC) clusters. Experimental results on a large-scale data set (1318 images at a scale of 10 billion pixels each) demonstrate the efficiency and effectiveness of the proposed algorithm for low-latency real-time applications. The framework proposed an effective and efficient system for extremely large histopathology image analysis. It is based on the multiple instance learning formulation for weakly-supervised learning for image classification, segmentation and clustering. When a max-margin concept is adopted for different clusters, we obtain further improvement in clustering performance.

  12. Multiple-Instance Learning for Anomaly Detection in Digital Mammography.

    2016-07-01

    This paper describes a computer-aided detection and diagnosis system for breast cancer, the most common form of cancer among women, using mammography. The system relies on the Multiple-Instance Learning (MIL) paradigm, which has proven useful for medical decision support in previous works from our team. In the proposed framework, breasts are first partitioned adaptively into regions. Then, features derived from the detection of lesions (masses and microcalcifications) as well as textural features, are extracted from each region and combined in order to classify mammography examinations as "normal" or "abnormal". Whenever an abnormal examination record is detected, the regions that induced that automated diagnosis can be highlighted. Two strategies are evaluated to define this anomaly detector. In a first scenario, manual segmentations of lesions are used to train an SVM that assigns an anomaly index to each region; local anomaly indices are then combined into a global anomaly index. In a second scenario, the local and global anomaly detectors are trained simultaneously, without manual segmentations, using various MIL algorithms (DD, APR, mi-SVM, MI-SVM and MILBoost). Experiments on the DDSM dataset show that the second approach, which is only weakly-supervised, surprisingly outperforms the first approach, even though it is strongly-supervised. This suggests that anomaly detectors can be advantageously trained on large medical image archives, without the need for manual segmentation.

    Full Text Available A neglected episode in West Malaysia’s subaltern history illustrates how simplistic Western notions of peace—and consequently, of surrender and resistance—can be. In the case of Semai in the Semai heartland, what seems like submission to external pressures turns out to be an ambiguous and ambivalent way of keeping the peace between Malays and Semai in the guise of adding new tools to traditional Semai internal peacekeeping praxis. Semai “double consciousness” of both their own reality and how Malays conceive of it thus allows them to avoid the imposition of external authority by creating a simulacrum thereof. “Surrender” and resistance overlap.

    2012-01-01

    A picture can be a powerful communication tool. However, creating pictures to illustrate patient instructions can be a costly and time-consuming task. Building on our prior research in this area, we developed a computer application that automatically converts text to pictures using natural language processing and computer graphics techniques. After iterative testing, the automated illustration system was evaluated using 49 previously unseen cardiology discharge instructions. The completeness of the system-generated illustrations was assessed by three raters using a three-level scale. The average inter-rater agreement for text correctly represented in the pictograph was about 66 percent. Since illustration in this context is intended to enhance rather than replace text, these results support the feasibility of conducting automated illustration.

  1. Producing Videotape Programs for Computer Training: An Example with AMA/NET

    Science.gov (United States)

    Novey, Donald W.

    1990-01-01

    To facilitate user proficiency with AMA/Net, an 80-minute training videotape has been produced. The production was designed to use videotape's advantages, where information and emotion are combined; and to accommodate its chief disadvantage, lack of resolution for fine text, with close-ups and graphics. Content of the videotape was conceived, outlined, demonstrated with simultaneous text capture, edited into script form, narration added, and scripts marked for videotaping and narrating. Videotaping was performed with actual keyboard sounds for realism. The recording was divided into four areas: office mock-up, keyboard close-ups, scan-conversion and screen close-ups. Once the footage was recorded, it was logged and rough-edited. Care was taken to balance the pace of the program with visual stimulation and amount of narration. The final edit was performed as a culmination of all scripts, video materials and rough edit, with graphics and steady change of visual information offsetting the static nature of the screen display. Carefully planned video programs can be a useful and economical adjunct in the training process for online services.

  2. A novel multiple instance learning method based on extreme learning machine.

    2015-01-01

    Since real-world data sets usually contain large instances, it is meaningful to develop efficient and effective multiple instance learning (MIL) algorithm. As a learning paradigm, MIL is different from traditional supervised learning that handles the classification of bags comprising unlabeled instances. In this paper, a novel efficient method based on extreme learning machine (ELM) is proposed to address MIL problem. First, the most qualified instance is selected in each bag through a single hidden layer feedforward network (SLFN) whose input and output weights are both initialed randomly, and the single selected instance is used to represent every bag. Second, the modified ELM model is trained by using the selected instances to update the output weights. Experiments on several benchmark data sets and multiple instance regression data sets show that the ELM-MIL achieves good performance; moreover, it runs several times or even hundreds of times faster than other similar MIL algorithms.

    Developing confidence in self-assessment is an important skill in becoming a self-regulated learner. This article describes the process undertaken by a group of educators of incorporating self-assessment in combination with psychomotor skill development with freshman students. Students were videotaped performing a wound-dressing change; the videotaping was immediately followed by a self-assessment of their performance using a faculty-generated checklist. Comparison of faculty and student ratings revealed the tendency for students to overrate their performance and identified discordance between students and faculty on several steps of the procedure. These evaluation findings are discussed and future directions explored.

    The importance of communication between patients and physicians has been proven in many previous studies. The authors analyzed the effect of interview skill education through videotapes which recorded students' interviews with real patients in the outpatient department of family medicine. This study was conducted with all students who chose the elective course of family medicine and one randomly selected student every week from an 'infectious internal medicine' class at Dongguk University Ilsan Hospital during the period from December 2008 to March 2011. All students performed a preliminary examination of a new patient at the outpatient department of family medicine. All consultations were videotaped. Feedback to the student was given on the same day by viewing the videotape together. After feedback, all students performed another preliminary examination of one new patient at the department of family medicine the same week. Three family medicine residents scored all videotapes using 10-item interview skill checklists. Many parts of the checklists were modified using the Arizona Clinical Interview Rating Scales. Thirty-three students participated. Of 10 items, nine showed increased scores after feedback. There was a significant change in four items after feedback: 'type of question' (before 2.36 ± 0.60, after 2.73 ± 0.72), 'timeline' (before 2.82 ± 0.68, after 3.18 ± 0.73), 'positive verbal reinforcement' (before 2.24 ± 0.56, after 2.61 ± 0.90), and the total score (before 21.70 ± 2.62, after 23.39 ± 3.13) (P skills using videotapes of students' preliminary consultations with real patients in outpatient settings, was effective in improving the interview areas of 'type of question,' 'timeline,' 'positive verbal reinforcement,' and the total interview scores.

  10. Illustrating the practice of statistics

    The practice of statistics involves analyzing data and planning data collection schemes to answer scientific questions. Issues often arise with the data that must be dealt with and can lead to new procedures. In analyzing data, these issues can sometimes be addressed through the statistical models that are developed. Simulation can also be helpful in evaluating a new procedure. Moreover, simulation coupled with optimization can be used to plan a data collection scheme. The practice of statistics as just described is much more than just using a statistical package. In analyzing the data, it involves understanding the scientific problem and incorporating the scientist's knowledge. In modeling the data, it involves understanding how the data were collected and accounting for limitations of the data where possible. Moreover, the modeling is likely to be iterative by considering a series of models and evaluating the fit of these models. Designing a data collection scheme involves understanding the scientist's goal and staying within hislher budget in terms of time and the available resources. Consequently, a practicing statistician is faced with such tasks and requires skills and tools to do them quickly. We have written this article for students to provide a glimpse of the practice of statistics. To illustrate the practice of statistics, we consider a problem motivated by some precipitation data that our relative, Masaru Hamada, collected some years ago. We describe his rain gauge observational study in Section 2. We describe modeling and an initial analysis of the precipitation data in Section 3. In Section 4, we consider alternative analyses that address potential issues with the precipitation data. In Section 5, we consider the impact of incorporating additional infonnation. We design a data collection scheme to illustrate the use of simulation and optimization in Section 6. We conclude this article in Section 7 with a discussion.

    The facility of the tape recording of a surgical operation, by means of simple manageable apparatuses and at low costs, especially in comparison with the former cinematography, makes it possible for all surgeons to record their own operative activity. Therefore at present the demonstration in video of surgical interventions is very common, but very often the video-tapes show surgical events only in straight chronological succession, as for facts of chronicle news. The simplification of the otherwise sophisticated digital technology of informatics elaboration of images makes more convenient and advisable to assemble the more meaningful sequences for a final product of higher scientific value. The digital technology gives at the best its contribution during the phase of post-production of the video-tape, where the surgeon himself can assemble an end product of more value because aimed to a scientific and rational communication. Thanks to such an elaboration the video-tape can aim not simply to become a good documentary, but also to achieve an educational purpose or becomes a truly scientific film. The initial video will be recorded following a specific project, the script, foreseeing and programming what has to be demonstrated of the surgical operation, establishing therefore in advance the most important steps of the intervention. The sequences recorded will then be assembled not necessarily in a chronological succession but integrating the moving images with static pictures, as drawings, schemes, tables, aside the picture-in picture technique, and besides the vocal descriptive comment. The cinema language has accustomed us to a series of passages among the different sequences as fading, cross-over, "flash-back", aiming to stimulate the psychological associative powers and encourage those critical. The video-tape can be opportunely shortened, paying attention to show only the essential phases of the operation for demonstrate only the core of the problem and utilize

  12. Fundamentals of Laparoscopic Surgery manual test: is videotaped performance assessment an option?

    2015-01-01

    In efforts to maintain standards required to evaluate the high-stakes assessment, Society of American Gastrointestinal and Endoscopic Surgeons Fundamentals of Laparoscopic Surgery (FLS) requires all new proctors to complete the train-the-proctor workshop. As the pool of FLS proctors expands, new methods to streamline training and quality assurance programs should be considered. We propose that videotaped performances of the FLS manual tasks may be an alternative proxy to live assessment for training of new proctors, but evaluation of proctors' measures from videotaped FLS performances is required before implementation. A 2-phased research consisted of capturing newly trained proctors' (n = 20) ratings of 3 similar FLS performances across 3 stations-live (Live), videotaped-laparoscopic only (Lap Only) view, and videotaped-dual (Dual) views, during the 2012 Society of American Gastrointestinal and Endoscopic Surgeons FLS train-the-proctor workshop. A month later, a sample of proctors (n = 9) viewed videotaped versions of live FLS performances originally observed during the workshop. Captured metrics include recognition of a predefined critical error for each task (dichotomously scored and summed) and time to complete each of the 5 tasks. Analysis of variance compared the proctors' summed ratings for similar performances across Live, Lap Only, and Dual views, whereas paired t test compared recorded times of Lap Only vs Dual views, Live vs web ratings, and proctors' recorded times across the Lap Only and Dual views. There were neither differences in ratings across Live, Lap Only, and Dual views (p = 0.49) nor in recorded times for performances viewed across Lap Only and Dual viewing options (p = 0.29 and 0.76, respectively). Mean summed performance ratings observed live (4.6) were higher than those observed via the web (4.0), although not significant (p = 0.051). There were no differences in recorded times for identical performances across Live and web observations (p

    Hajimirsadeghi, Hossein; Mori, Greg

    2017-09-01

    We propose a probabilistic graphical framework for multi-instance learning (MIL) based on Markov networks. This framework can deal with different levels of labeling ambiguity (i.e., the portion of positive instances in a bag) in weakly supervised data by parameterizing cardinality potential functions. Consequently, it can be used to encode different cardinality-based multi-instance assumptions, ranging from the standard MIL assumption to more general assumptions. In addition, this framework can be efficiently used for both binary and multiclass classification. To this end, an efficient inference algorithm and a discriminative latent max-margin learning algorithm are introduced to train and test the proposed multi-instance Markov network models. We evaluate the performance of the proposed framework on binary and multi-class MIL benchmark datasets as well as two challenging computer vision tasks: cyclist helmet recognition and human group activity recognition. Experimental results verify that encoding the degree of ambiguity in data can improve classification performance.

    1989-01-01

    This illustration depicts a side view of the Hubble Space Telescope (HST). The HST is the product of a partnership between NASA, European Space Agency Contractors, and the international community of astronomers. It is named after Edwin P. Hubble, an American Astronomer who discovered the expanding nature of the universe and was the first to realize the true nature of galaxies. The purpose of the HST, the most complex and sensitive optical telescope ever made, is to study the cosmos from a low-Earth orbit. By placing the telescope in space, astronomers are able to collect data that is free of the Earth's atmosphere. The HST detects objects 25 times fainter than the dimmest objects seen from Earth and provides astronomers with an observable universe 250 times larger than visible from ground-based telescopes, perhaps as far away as 14 billion light-years. The HST views galaxies, stars, planets, comets, possibly other solar systems, and even unusual phenomena such as quasars, with 10 times the clarity of ground-based telescopes. The major elements of the HST are the Optical Telescope Assembly (OTA), the Support System Module (SSM), and the Scientific Instruments (SI). The HST is approximately the size of a railroad car, with two cylinders joined together and wrapped in a silvery reflective heat shield blanket. Wing-like solar arrays extend horizontally from each side of these cylinders, and dish-shaped anternas extend above and below the body of the telescope. The HST was deployed from the Space Shuttle Discovery (STS-31 mission) into Earth orbit in April 1990. The Marshall Space Flight Center had responsibility for design, development, and construction of the HST. The Perkin-Elmer Corporation, in Danbury, Connecticut, developed the optical system and guidance sensors. The Lockheed Missile and Space Company of Sunnyvale, California produced the protective outer shroud and spacecraft systems, and assembled and tested the finished telescope.

    2001-01-01

    This illustration is an orbiter cutaway view with callouts. The orbiter is both the brains and heart of the Space Transportation System (STS). About the same size and weight as a DC-9 aircraft, the orbiter contains the pressurized crew compartment (which can normally carry up to seven crew members), the huge cargo bay, and the three main engines mounted on its aft end. There are three levels to the crew cabin. Uppermost is the flight deck where the commander and the pilot control the mission. The middeck is where the gallery, toilet, sleep stations, and storage and experiment lockers are found for the basic needs of weightless daily living. Also located in the middeck is the airlock hatch into the cargo bay and space beyond. It is through this hatch and airlock that astronauts go to don their spacesuits and marned maneuvering units in preparation for extravehicular activities, more popularly known as spacewalks. The Space Shuttle's cargo bay is adaptable to hundreds of tasks. Large enough to accommodate a tour bus (60 x 15 feet or 18.3 x 4.6 meters), the cargo bay carries satellites, spacecraft, and spacelab scientific laboratories to and from Earth orbit. It is also a work station for astronauts to repair satellites, a foundation from which to erect space structures, and a hold for retrieved satellites to be returned to Earth. Thermal tile insulation and blankets (also known as the thermal protection system or TPS) cover the underbelly, bottom of the wings, and other heat-bearing surfaces of the orbiter to protect it during its fiery reentry into the Earth's atmosphere. The Shuttle's 24,000 individual tiles are made primarily of pure-sand silicate fibers, mixed with a ceramic binder. The solid rocket boosters (SRB's) are designed as an in-house Marshall Space Flight Center project, with United Space Boosters as the assembly and refurbishment contractor. The solid rocket motor (SRM) is provided by the Morton Thiokol Corporation.

  19. Coarse-Grain QoS-Aware Dynamic Instance Provisioning for Interactive Workload in the Cloud

    2014-01-01

    Full Text Available Cloud computing paradigm renders the Internet service providers (ISPs with a new approach to deliver their service with less cost. ISPs can rent virtual machines from the Infrastructure-as-a-Service (IaaS provided by the cloud rather than purchasing them. In addition, commercial cloud providers (CPs offer diverse VM instance rental services in various time granularities, which provide another opportunity for ISPs to reduce cost. We investigate a Coarse-grain QoS-aware Dynamic Instance Provisioning (CDIP problem for interactive workload in the cloud from the perspective of ISPs. We formulate the CDIP problem as an optimization problem where the objective is to minimize the VM instance rental cost and the constraint is the percentile delay bound. Since the Internet traffic shows a strong self-similar property, it is hard to get an analytical form of the percentile delay constraint. To address this issue, we purpose a lookup table structure together with a learning algorithm to estimate the performance of the instance provisioning policy. This approach is further extended with two function approximations to enhance the scalability of the learning algorithm. We also present an efficient dynamic instance provisioning algorithm, which takes full advantage of the rental service diversity, to determine the instance rental policy. Extensive simulations are conducted to validate the effectiveness of the proposed algorithms.

  1. Twin Support Vector Machine for Multiple Instance Learning Based on Bag Dissimilarities

    Directory of Open Access Journals (Sweden)

    Divya Tomar

    2016-01-01

    Full Text Available In multiple instance learning (MIL framework, an object is represented by a set of instances referred to as bag. A positive class label is assigned to a bag if it contains at least one positive instance; otherwise a bag is labeled with negative class label. Therefore, the task of MIL is to learn a classifier at bag level rather than at instance level. Traditional supervised learning approaches cannot be applied directly in such kind of situation. In this study, we represent each bag by a vector of its dissimilarities to the other existing bags in the training dataset and propose a multiple instance learning based Twin Support Vector Machine (MIL-TWSVM classifier. We have used different ways to represent the dissimilarity between two bags and performed a comparative analysis of them. The experimental results on ten benchmark MIL datasets demonstrate that the proposed MIL-TWSVM classifier is computationally inexpensive and competitive with state-of-the-art approaches. The significance of the experimental results has been tested by using Friedman statistic and Nemenyi post hoc tests.

  2. Improving Multi-Instance Multi-Label Learning by Extreme Learning Machine

    2016-05-01

    Full Text Available Multi-instance multi-label learning is a learning framework, where every object is represented by a bag of instances and associated with multiple labels simultaneously. The existing degeneration strategy-based methods often suffer from some common drawbacks: (1 the user-specific parameter for the number of clusters may incur the effective problem; (2 SVM may bring a high computational cost when utilized as the classifier builder. In this paper, we propose an algorithm, namely multi-instance multi-label (MIML-extreme learning machine (ELM, to address the problems. To our best knowledge, we are the first to utilize ELM in the MIML problem and to conduct the comparison of ELM and SVM on MIML. Extensive experiments have been conducted on real datasets and synthetic datasets. The results show that MIMLELM tends to achieve better generalization performance at a higher learning speed.

    2016-01-01

    An improved online multiple instance learning (IMIL) for a visual tracking algorithm is proposed. In the IMIL algorithm, the importance of each instance contributing to a bag probability is with respect to their probabilities. A selection strategy based on an inner product is presented to choose weak classifier from a classifier pool, which avoids computing instance probabilities and bag probability M times. Furthermore, a feedback strategy is presented to update weak classifiers. In the feedback update strategy, different weights are assigned to the tracking result and template according to the maximum classifier score. Finally, the presented algorithm is compared with other state-of-the-art algorithms. The experimental results demonstrate that the proposed tracking algorithm runs in real-time and is robust to occlusion and appearance changes.

  8. Instances or Sequences? Improving the State of the Art of Qualitative Research

    Directory of Open Access Journals (Sweden)

    David Silverman

    2005-09-01

    Full Text Available Numbers apparently talk. With few numbers, qualitative researchers appear to rely on examples or instances to support their analysis. Hence research reports routinely display data extracts which serve as telling instances of some claimed phenomenon. However, the use of such an evidential base rightly provokes the charge of (possible anecdotalism, i.e. choosing just those extracts which support your argument. I suggest that this methodological problem is best addressed by returning to those features of our theoretical roots which tend to distinguish what we do from the work of quantitative social scientists. Although SAUSSURE is most cited in linguistics and structural anthropology, he provides a simple rule that applies to us all. In a rebuke to our reli­ance on instances, SAUSSURE tells us "no mean­ing exists in a single item". Everything depends upon how single items (elements are articulated. One everyday activity in which the social world is articulated is through the construction of se­quences. Just as participants attend to the se­quential placing of interactional "events", so should social scientists. Using examples drawn from focus groups, fieldnotes and audiotapes, I argue that the identification of such sequences rather than the citing of instances should constitute a prime test for the adequacy of any claim about qualitative data.

    Xu, Yonghui; Min, Huaqing; Song, Hengjie; Wu, Qingyao

    2016-08-01

    Multi-instance multi-label (MIML) learning has been proven to be effective for the genome-wide protein function prediction problems where each training example is associated with not only multiple instances but also multiple class labels. To find an appropriate MIML learning method for genome-wide protein function prediction, many studies in the literature attempted to optimize objective functions in which dissimilarity between instances is measured using the Euclidean distance. But in many real applications, Euclidean distance may be unable to capture the intrinsic similarity/dissimilarity in feature space and label space. Unlike other previous approaches, in this paper, we propose to learn a multi-instance multi-label distance metric learning framework (MIMLDML) for genome-wide protein function prediction. Specifically, we learn a Mahalanobis distance to preserve and utilize the intrinsic geometric information of both feature space and label space for MIML learning. In addition, we try to deal with the sparsely labeled data by giving weight to the labeled data. Extensive experiments on seven real-world organisms covering the biological three-domain system (i.e., archaea, bacteria, and eukaryote; Woese et al., 1990) show that the MIMLDML algorithm is superior to most state-of-the-art MIML learning algorithms.

    Cano, Emilio L; Moguerza, Javier M; Alonso-Ayuso, Antonio

    2015-12-01

    Optimization instances relate to the input and output data stemming from optimization problems in general. Typically, an optimization problem consists of an objective function to be optimized (either minimized or maximized) and a set of constraints. Thus, objective and constraints are jointly a set of equations in the optimization model. Such equations are a combination of decision variables and known parameters, which are usually related to a set domain. When this combination is a linear combination, we are facing a classical Linear Programming (LP) problem. An optimization instance is related to an optimization model. We refer to that model as the Symbolic Model Specification (SMS) containing all the sets, variables, and parameters symbols and relations. Thus, a whole instance is composed by the SMS, the elements in each set, the data values for all the parameters, and, eventually, the optimal decisions resulting from the optimization solution. This data article contains several optimization instances from a real-world optimization problem relating to investment planning on energy efficient technologies at the building level.

  16. Quantification of video-taped images in microcirculation research using inexpensive imaging software (Adobe Photoshop).

    Science.gov (United States)

    Brunner, J; Krummenauer, F; Lehr, H A

    2000-04-01

    Study end-points in microcirculation research are usually video-taped images rather than numeric computer print-outs. Analysis of these video-taped images for the quantification of microcirculatory parameters usually requires computer-based image analysis systems. Most software programs for image analysis are custom-made, expensive, and limited in their applicability to selected parameters and study end-points. We demonstrate herein that an inexpensive, commercially available computer software (Adobe Photoshop), run on a Macintosh G3 computer with inbuilt graphic capture board provides versatile, easy to use tools for the quantification of digitized video images. Using images obtained by intravital fluorescence microscopy from the pre- and postischemic muscle microcirculation in the skinfold chamber model in hamsters, Photoshop allows simple and rapid quantification (i) of microvessel diameters, (ii) of the functional capillary density and (iii) of postischemic leakage of FITC-labeled high molecular weight dextran from postcapillary venules. We present evidence of the technical accuracy of the software tools and of a high degree of interobserver reliability. Inexpensive commercially available imaging programs (i.e., Adobe Photoshop) provide versatile tools for image analysis with a wide range of potential applications in microcirculation research.

  20. Semi-Supervised Affinity Propagation with Soft Instance-Level Constraints.

    Science.gov (United States)

    Arzeno, Natalia M; Vikalo, Haris

    2015-05-01

    Soft-constraint semi-supervised affinity propagation (SCSSAP) adds supervision to the affinity propagation (AP) clustering algorithm without strictly enforcing instance-level constraints. Constraint violations lead to an adjustment of the AP similarity matrix at every iteration of the proposed algorithm and to addition of a penalty to the objective function. This formulation is particularly advantageous in the presence of noisy labels or noisy constraints since the penalty parameter of SCSSAP can be tuned to express our confidence in instance-level constraints. When the constraints are noiseless, SCSSAP outperforms unsupervised AP and performs at least as well as the previously proposed semi-supervised AP and constrained expectation maximization. In the presence of label and constraint noise, SCSSAP results in a more accurate clustering than either of the aforementioned established algorithms. Finally, we present an extension of SCSSAP which incorporates metric learning in the optimization objective and can further improve the performance of clustering.

    Shimizu, Tadaaki; Kimoto, Masaya; Yoshimura, Hiroki; Namiki, Toshie; Isu, Naoki; Sugata, Kazuhiro

    We proposed two selection methods, 1) selection method by using phonemic environmental resemblance score (PER method), and 2) selection method by searching minimal connective distortion path (MLD method), for small scale speech synthesis system. PER method requires phonemic environmental information for each VCV instance in a VCV unit dictionary. This paper investigated experimentally to what extent we can reduce the phonemic environmental information with keeping high quality of synthesized speech. We verified that two phonemes frontward and one phoneme rearward range to a current VCV instance is enough to synthesize similar quality of speech as five phonemes frontward and five phonemes rearward. This result gives an experimental basis on minimizing a size of VCV unit dictionary.

  2. Biologically inspired scene context for object detection using a single instance.

    Directory of Open Access Journals (Sweden)

    Changxin Gao

    Full Text Available This paper presents a novel object detection method using a single instance from the object category. Our method uses biologically inspired global scene context criteria to check whether every individual location of the image can be naturally replaced by the query instance, which indicates whether there is a similar object at this location. Different from the traditional detection methods that only look at individual locations for the desired objects, our method evaluates the consistency of the entire scene. It is therefore robust to large intra-class variations, occlusions, a minor variety of poses, low-revolution conditions, background clutter etc., and there is no off-line training. The experimental results on four datasets and two video sequences clearly show the superior robustness of the proposed method, suggesting that global scene context is important for visual detection/localization.

    Directory of Open Access Journals (Sweden)

    Elvio Giasson

    2015-09-01

    Full Text Available A critical issue in digital soil mapping (DSM is the selection of data sampling method for model training. One emerging approach applies instance selection to reduce the size of the dataset by drawing only relevant samples in order to obtain a representative subset that is still large enough to preserve relevant information, but small enough to be easily handled by learning algorithms. Although there are suggestions to distribute data sampling as a function of the soil map unit (MU boundaries location, there are still contradictions among research recommendations for locating samples either closer or more distant from soil MU boundaries. A study was conducted to evaluate instance selection methods based on spatially-explicit data collection using location in relation to soil MU boundaries as the main criterion. Decision tree analysis was performed for modeling digital soil class mapping using two different sampling schemes: a selecting sampling points located outside buffers near soil MU boundaries, and b selecting sampling points located within buffers near soil MU boundaries. Data was prepared for generating classification trees to include only data points located within or outside buffers with widths of 60, 120, 240, 360, 480, and 600m near MU boundaries. Instance selection methods using both spatial selection of methods was effective for reduced size of the dataset used for calibrating classification tree models, but failed to provide advantages to digital soil mapping because of potential reduction in the accuracy of classification tree models.

  7. Sparse Representation Based Multi-Instance Learning for Breast Ultrasound Image Classification

    Directory of Open Access Journals (Sweden)

    Lu Bing

    2017-01-01

    Full Text Available We propose a novel method based on sparse representation for breast ultrasound image classification under the framework of multi-instance learning (MIL. After image enhancement and segmentation, concentric circle is used to extract the global and local features for improving the accuracy in diagnosis and prediction. The classification problem of ultrasound image is converted to sparse representation based MIL problem. Each instance of a bag is represented as a sparse linear combination of all basis vectors in the dictionary, and then the bag is represented by one feature vector which is obtained via sparse representations of all instances within the bag. The sparse and MIL problem is further converted to a conventional learning problem that is solved by relevance vector machine (RVM. Results of single classifiers are combined to be used for classification. Experimental results on the breast cancer datasets demonstrate the superiority of the proposed method in terms of classification accuracy as compared with state-of-the-art MIL methods.

  8. Patients, doctors, and videotape: a prescription for creating optimal healing environments?

    Science.gov (United States)

    Frankel, Richard M; Sung, Sue Hee; Hsu, John T

    2005-01-01

    Despite repeated calls for greater patient autonomy, shared decision making, and exploration of patient preferences, relatively little is known about how patients actually experience care as a face-to-face interactional process. A selected review of the literature in this area suggests that important asymmetries exist. Key among them is the tendency to report experiences from the point of view of only one member of the doctor-patient dyad. Thus, patients might report on their experiences of the system gone awry or professionals might attempt to understand the root cause(s) of an error by describing the conditions under which it occurred. Either way, information about the experience of care tends to be reported as a "my side" telling. Optimal healing environments are defined as health care contexts that are based upon mutual respect and build positive, resilient relationships among participants, using the qualities and resources of those relationships to enhance health. Understanding optimal healing environments also requires a knowledge of how doctors and patients share time and space together in the consultation (an etic or outsider perspective) and also a knowledge of the participants' experience of their time together (an emic or insider perspective). After reviewing its methodological roots, the IMPACT approach (Interactive Methodology for Preserving and Analyzing Clinical Transactions) using videotaped encounters along with independent commentaries by participants is described and applied in two different types of analyses: one in which the doctor-patient dyad is the unit of measure; the second in which physicians are stratified by having historically high or low satisfaction scores. In the latter approach, doctors' and patients' comments are compared across strata. At the dyadic level, and despite large gaps in income and social status, doctors and patients exhibit a strong tendency to cluster in terms of where they comment, so much so that in a pilot study

  14. Phenotype Prediction from Metagenomic Data Using Clustering and Assembly with Multiple Instance Learning (CAMIL).

    2017-10-04

    The recent advent of Metagenome Wide Association Studies (MGWAS) provides insight into the role of microbes on human health and disease. However, the studies present several computational challenges. In this paper we demonstrate a novel, efficient, and effective Multiple Instance Learning (MIL) based computational pipeline to predict patient phenotype from metagenomic data. MIL methods have the advantage that besides predicting the clinical phenotype, we can infer the instance level label or role of microbial sequence reads in the specific disease. Specifically, we use a Bag of Words method, which has been shown to be one of the most effective and efficient MIL methods. This involves assembly of the metagenomic sequence data, clustering of the assembled contigs, extracting features from the contigs, and using an SVM classifier to predict patient labels and identify the most relevant sequence clusters. With the exception of the given labels for the patients, this entire process is de novo (unsupervised). We call our pipeline "CAMIL", which stands for Clustering and Assembly with Multiple Instance Learning. We use multiple state-of-the-art clustering methods for feature extraction, evaluate and comparison of the performance of our proposed approach for each of these clustering methods. We also present a fast and scalable pre-clustering algorithm as a preprocessing step for our proposed pipeline. Our approach achieves efficiency by partitioning the large number of sequence reads into groups (called canopies) using locality sensitive hashing (LSH). These canopies are then refined by using state-of-the-art sequence clustering algorithms. We use data from a well-known MGWAS study of patients with Type-2 Diabetes and show that our pipeline significantly outperforms the classifier used in that paper, as well as other common MIL methods.

  15. On Combining Multiple-Instance Learning and Active Learning for Computer-Aided Detection of Tuberculosis.

    The major advantage of multiple-instance learning (MIL) applied to a computer-aided detection (CAD) system is that it allows optimizing the latter with case-level labels instead of accurate lesion outlines as traditionally required for a supervised approach. As shown in previous work, a MIL-based CAD system can perform comparably to its supervised counterpart considering complex tasks such as chest radiograph scoring in tuberculosis (TB) detection. However, despite this remarkable achievement, the uncertainty inherent to MIL can lead to a less satisfactory outcome if analysis at lower levels (e.g., regions or pixels) is needed. This issue may seriously compromise the applicability of MIL to tasks related to quantification or grading, or detection of highly localized lesions. In this paper, we propose to reduce uncertainty by embedding a MIL classifier within an active learning (AL) framework. To minimize the labeling effort, we develop a novel instance selection mechanism that exploits the MIL problem definition through one-class classification. We adapt this mechanism to provide meaningful regions instead of individual instances for expert labeling, which is a more appropriate strategy given the application domain. In addition, and contrary to usual AL methods, a single iteration is performed. To show the effectiveness of our approach, we compare the output of a MIL-based CAD system trained with and without the proposed AL framework. The task is to detect textural abnormalities related to TB. Both quantitative and qualitative evaluations at the pixel level are carried out. Our method significantly improves the MIL-based classification.

  16. Synergistic Instance-Level Subspace Alignment for Fine-Grained Sketch-Based Image Retrieval.

    We study the problem of fine-grained sketch-based image retrieval. By performing instance-level (rather than category-level) retrieval, it embodies a timely and practical application, particularly with the ubiquitous availability of touchscreens. Three factors contribute to the challenging nature of the problem: (i) free-hand sketches are inherently abstract and iconic, making visual comparisons with photos difficult, (ii) sketches and photos are in two different visual domains, i.e. black and white lines vs. color pixels, and (iii) fine-grained distinctions are especially challenging when executed across domain and abstraction-level. To address these challenges, we propose to bridge the image-sketch gap both at the high-level via parts and attributes, as well as at the low-level, via introducing a new domain alignment method. More specifically, (i) we contribute a dataset with 304 photos and 912 sketches, where each sketch and image is annotated with its semantic parts and associated part-level attributes. With the help of this dataset, we investigate (ii) how strongly-supervised deformable part-based models can be learned that subsequently enable automatic detection of part-level attributes, and provide pose-aligned sketch-image comparisons. To reduce the sketch-image gap when comparing low-level features, we also (iii) propose a novel method for instance-level domain-alignment, that exploits both subspace and instance-level cues to better align the domains. Finally (iv) these are combined in a matching framework integrating aligned low-level features, mid-level geometric structure and high-level semantic attributes. Extensive experiments conducted on our new dataset demonstrate effectiveness of the proposed method.

    A system for automatically training and spotting signs from continuous sign language sentences is presented. We propose a novel multiple instance learning density matrix algorithm which automatically extracts isolated signs from full sentences using the weak and noisy supervision of text translations. The automatically extracted isolated samples are then utilized to train our spatiotemporal gesture and hand posture classifiers. The experiments were carried out to evaluate the performance of the automatic sign extraction, hand posture classification, and spatiotemporal gesture spotting systems. We then carry out a full evaluation of our overall sign spotting system which was automatically trained on 30 different signs.

  20. Instance-based classifiers applied to medical databases: diagnosis and knowledge extraction.

    Gagliardi, Francesco

    2011-07-01

    The aim of this paper is to study the feasibility and the performance of some classifier systems belonging to family of instance-based (IB) learning as second-opinion diagnostic tools and as tools for the knowledge extraction phase in the process of knowledge discovery in clinical databases. We consider three clinical databases: one relating to the differential diagnosis of erythemato-squamous diseases, the second to the diagnosis of the onset of diabetes mellitus and the third dealing with a problem of diagnostic imaging in nuclear cardiology. We apply five IB classifiers to each database; two are based on exemplars, one is based on prototypes and two are hybrid. One of the latter classifiers is a new classifier introduced here and is called prototype exemplar learning classifier (PEL-C). We use cross-validation techniques to evaluate and compare the performances of several classifier systems as diagnostic tools, considering indexes such as accuracy, sensitivity, specificity, and conciseness of class representations. Moreover we analyze the number and the type of instances that represent the diagnostic classes learnt by each classifier to evaluate and compare their knowledge extraction capabilities. An examination of the experimental results shows that classifiers with the best classification performances are the optimized k-nearest neighbour classifier (k-NNC) and PEL-C. The k-NNC uses the highest number of representative instances, 100% of the entire database, whereas PEL-C uses a far lesser number of representative instances: equal, on the average, to the 3% of the database. As tools for knowledge extraction, we interpret the kind of class representations obtained by IB classifiers as a form of nosological knowledge. Additionally, we report the most interesting diagnostic class representations to be those extracted by PEL-C because they are composed of a mixture of abstracted prototypical cases (syndromes) and selected atypical clinical cases. This study shows

    Robi Kroflič

    2014-03-01

    Full Text Available The key hypothesis of the article is that successful inter-mediation of art to vulnerable groups of people (including children depends on the correct identification of the nature of an artistic act and on the meaning that handicap—as an instance of otherness—has in the life of artists and spectators. A just access to the artistic experience is basically not the question of the distribution of artistic production (since if artistic object is principally accessible to all people, it will not reach vulnerable groups of spectators, but of ensuring artistic creativity and presentation. This presupposes a spectator as a competent being who is able to interact with the artistic object without our interpretative explanation and who is sensible to the instance of otherness (handicap is merely a specific form of otherness. The theory of emancipation from J. Ranciere, the theory of recognition from A. Honneth, and the theory of narration from P. Ricoeur and R. Kearney, as well as our experiences with a comprehensive inductive approach and artistic experience as one of its basic educational methods offer us a theoretical framework for such a model of art inter-mediation.

    Al-Sahaf, Harith; Zhang, Mengjie; Johnston, Mark

    2016-01-01

    In the computer vision and pattern recognition fields, image classification represents an important yet difficult task. It is a challenge to build effective computer models to replicate the remarkable ability of the human visual system, which relies on only one or a few instances to learn a completely new class or an object of a class. Recently we proposed two genetic programming (GP) methods, one-shot GP and compound-GP, that aim to evolve a program for the task of binary classification in images. The two methods are designed to use only one or a few instances per class to evolve the model. In this study, we investigate these two methods in terms of performance, robustness, and complexity of the evolved programs. We use ten data sets that vary in difficulty to evaluate these two methods. We also compare them with two other GP and six non-GP methods. The results show that one-shot GP and compound-GP outperform or achieve results comparable to competitor methods. Moreover, the features extracted by these two methods improve the performance of other classifiers with handcrafted features and those extracted by a recently developed GP-based method in most cases.

  3. Entropy-Weighted Instance Matching Between Different Sourcing Points of Interest

    Directory of Open Access Journals (Sweden)

    Lin Li

    2016-01-01

    Full Text Available The crucial problem for integrating geospatial data is finding the corresponding objects (the counterpart from different sources. Most current studies focus on object matching with individual attributes such as spatial, name, or other attributes, which avoids the difficulty of integrating those attributes, but at the cost of an ineffective matching. In this study, we propose an approach for matching instances by integrating heterogeneous attributes with the allocation of suitable attribute weights via information entropy. First, a normalized similarity formula is developed, which can simplify the calculation of spatial attribute similarity. Second, sound-based and word segmentation-based methods are adopted to eliminate the semantic ambiguity when there is a lack of a normative coding standard in geospatial data to express the name attribute. Third, category mapping is established to address the heterogeneity among different classifications. Finally, to address the non-linear characteristic of attribute similarity, the weights of the attributes are calculated by the entropy of the attributes. Experiments demonstrate that the Entropy-Weighted Approach (EWA has good performance both in terms of precision and recall for instance matching from different data sets.

    The information available on-line and off-line, from open as well as from private sources, is growing at an exponential rate and places an increasing demand on the limited resources of Law Enforcement Agencies (LEAs). The absence of appropriate tools and techniques to collect, process, and analyze the volumes of complex and heterogeneous data has created a severe information overload. If a solution is not found, the impact on law enforcement will be dramatic, e.g. because important evidence is missed or the investigation time is too long. Furthermore, there is an uneven level of capabilities to deal with the large volumes of complex and heterogeneous data that come from multiple open and private sources at national level across the EU, which hinders cooperation and information sharing. Consequently, there is a pertinent need to develop tools, systems and processes which expedite online investigations. In this paper, we describe a suite of analysis tools to identify and localize generic concepts, instances of objects and logos in images, which constitutes a significant portion of everyday law enforcement data. We describe how incremental learning based on only a few examples and large-scale indexing are addressed in both concept detection and instance search. Our search technology allows querying of the database by visual examples and by keywords. Our tools are packaged in a Docker container to guarantee easy deployment on a system and our tools exploit possibilities provided by open source toolboxes, contributing to the technical autonomy of LEAs.

    The improvement of ultrasound scan techniques is enabling ever earlier prenatal diagnosis of developmental anomalies. In France, apart from cases where the mother's life is endangered, the detection of "particularly serious" conditions, and conditions that are "incurable at the time of diagnosis" are the only instances in which a therapeutic abortion can be performed, this applying up to the 9th month of pregnancy. Thus numerous conditions, despite the fact that they cause distress or pain or are socially disabling, do not qualify for therapeutic abortion, despite sometimes pressing demands from parents aware of the difficulties in store for their child and themselves, in a society that is not very favourable towards the integration and self-fulfilment of people with a disability. Cleft lip and palate (CLP), although it can be completely treated, is one of the conditions that considerably complicates the lives of child and parents. Nevertheless, the recent scope for making very early diagnosis of CLP, before the deadline for legal voluntary abortion, has not led to any wave of abortions. CLP in France has the benefit of a exceptional care plan, targeting both the health and the integration of the individuals affected. This article sets out, via the emblematic instance of CLP, to show how present fears of an emerging "domestic" or liberal eugenic trend could become redundant if disability is addressed politically and medically, so that individuals with a disability have the same social rights as any other citizen.

    Traditionally, bite mark photographs have been used to study statically a dynamic event. With the advent of the compact video camcorder, odontologists can now document bite marks on video tape and, in some instances, with the model of the suspect's dentition, may be able to record the dynamics of a bite on human flesh. A review of two cases and equipment used is discussed.

  10. More than pretty pictures? How illustrations affect parent-child story reading and children’s story recall

    Directory of Open Access Journals (Sweden)

    Andrea Follmer Greenhoot

    2014-07-01

    Full Text Available Previous research showed that story illustrations fail to enhance young preschoolers’ memories when they accompany a pre-recorded story (e.g., Greenhoot & Semb, 2008. In this study we tested whether young children might benefit from illustrations in a more interactive story-reading context. For instance, illustrations might influence parent-child reading interactions, and thus children’s story comprehension and recall. Twenty-six 3.5- to 4.5-year-olds and their primary caregivers were randomly assigned to an Illustrated or Non-Illustrated story-reading condition, and parents were instructed to read or tell the story as they normally would read with their child. Children recalled the story after a distracter and again after one week. Analyses of the story-reading interactions showed that the illustrations prompted more interactive story reading and more parent and child behaviors known to predict improved literacy outcomes. Furthermore,in the first memory interview, children in the Illustrated condition recalled more story events than those in the Non-Illustrated condition. Story reading measures predicted recall, but did not completely account for picture effects. These results suggest that illustrations enhance young preschoolers’ story recall in an interactive story reading context, perhaps because the joint attention established in this context supports children’s processing of the illustrations.

    2009-03-01

    Full Text Available Abstract Background Cartoon-style illustrative renderings of proteins can help clarify structural features that are obscured by space filling or balls and sticks style models, and recent advances in programmable graphics cards offer many new opportunities for improving illustrative renderings. Results The ProteinShader program, a new tool for macromolecular visualization, uses information from Protein Data Bank files to produce illustrative renderings of proteins that approximate what an artist might create by hand using pen and ink. A combination of Hermite and spherical linear interpolation is used to draw smooth, gradually rotating three-dimensional tubes and ribbons with a repeating pattern of texture coordinates, which allows the application of texture mapping, real-time halftoning, and smooth edge lines. This free platform-independent open-source program is written primarily in Java, but also makes extensive use of the OpenGL Shading Language to modify the graphics pipeline. Conclusion By programming to the graphics processor unit, ProteinShader is able to produce high quality images and illustrative rendering effects in real-time. The main feature that distinguishes ProteinShader from other free molecular visualization tools is its use of texture mapping techniques that allow two-dimensional images to be mapped onto the curved three-dimensional surfaces of ribbons and tubes with minimum distortion of the images.

    Pan, Qiang; Zhang, Gang; Zhang, Xiao-Yan; Huang, Zhi-Ming; Xiong, Jie

    2012-01-01

    We propose a similarity-based learning style algorithm by regarding each image as a multi-instance (MI) sample for image classification. An image featured as vectorial representation interesting regions is transferred to a MI sample. Then a similarity like matrix is constructed using MI kernel between given images and some carefully selected base images, as the new representation of given images. Three selection strategies are proposed to build the base images set to find an optimal solution. A Weka implementation decision tree is used as the main learner in this paper. Experiments on image data repository ALOI and Corel Image 2000 show the effectiveness of the proposed algorithm compared to some previous based line methods.

  1. The Naueti relationship terminology: A new instance of asymmetric prescription from East Timor

    Directory of Open Access Journals (Sweden)

    David Hicks

    2008-12-01

    Full Text Available Relationship terminologies of an asymmetric prescriptive character are widespread throughout mainland and insular Southeast Asia. Their western limit is marked by the Kachin of northern Burma (Leach 1961:28-53 while their eastern limit is marked by the Mambai people of central East Timor (Figures 1 and 2. Between these limits are such other instances as occur, for example, among the Lamet of Cambodia (Needham 1960, the various Batak groups of Sumatra (Rodgers 1984, and the Rindi of eastern Sumba (Forth 1981. The principal intention of the present paper is to establish the existence of a new asymmetric prescriptive terminology in East Timor, and by doing so provide empirical justification for adjusting the easternmost limits of nomenclatures of this kind. A subsidiary intent is to offer a contribution to current speculations regarding the transformation of relationship terminologies in eastern Indonesia (Guermonprez 1998; Smedal 2002.

    Computational models of cognition provide an interface to connect advanced mathematical tools and methods to empirically supported theories of behavior in psychology, cognitive science, and neuroscience. In this article, we consider a computational model of instance-based learning, implemented in the ACT-R cognitive architecture. We propose an approach for obtaining mathematical reformulations of such cognitive models that improve their computational tractability. For the well-established Sugar Factory dynamic decision making task, we conduct a simulation study to analyze central model parameters. We show how mathematical optimization techniques can be applied to efficiently identify optimal parameter values with respect to different optimization goals. Beyond these methodological contributions, our analysis reveals the sensitivity of this particular task with respect to initial settings and yields new insights into how average human performance deviates from potential optimal performance. We conclude by discussing possible extensions of our approach as well as future steps towards applying more powerful derivative-based optimization methods.

  3. Interpreting Black-Box Classifiers Using Instance-Level Visual Explanations

    2017-05-14

    To realize the full potential of machine learning in diverse real- world domains, it is necessary for model predictions to be readily interpretable and actionable for the human in the loop. Analysts, who are the users but not the developers of machine learning models, often do not trust a model because of the lack of transparency in associating predictions with the underlying data space. To address this problem, we propose Rivelo, a visual analytic interface that enables analysts to understand the causes behind predictions of binary classifiers by interactively exploring a set of instance-level explanations. These explanations are model-agnostic, treating a model as a black box, and they help analysts in interactively probing the high-dimensional binary data space for detecting features relevant to predictions. We demonstrate the utility of the interface with a case study analyzing a random forest model on the sentiment of Yelp reviews about doctors.

    Full Text Available Smart communities provide technologies for monitoring social behaviors inside communities. The technologies that support knowledge building should consider the cultural background of community members. The studies of the influence of the culture on knowledge building is limited. Just a few works consider digital traces of individuals that they explain using cultural values and beliefs. In this work, we analyze 13 Wikipedia instances where users with different cultural background build knowledge in different ways. We compare edits of users. Using social network analysis we build and analyze co- authorship networks and watch the networks evolution. We explain the differences we have found using Hofstede dimensions and Schwartz cultural values and discuss implications for the design of smart community technologies. Our findings provide insights in requirements for technologies used for smart communities in different cultures.

    2013-12-01

    Full Text Available This study, based on the framework of Sociodiscursive Interactionism, is focused on the role of some agentive instances in text genre advertisements. Firstly, it aims at demonstrating that depending on the acting and social practices, the role of these agents is different and it can be distinctly materialized in these text genres. Secondly, it will show that according to different activities linked to these genres, one can imagine the existence of different levels of “actoriality”. This article is based on the analysis of some examples of text genre advertisements that were in circulation in Portugal from 2007 to 2011. Some examples come from the non-profitable activity, while the others are taken from the activity of production and marketing of wine.

    2017-07-01

    Age-related Macular Degeneration (AMD) is a kind of macular disease which mostly occurs in old people,and it may cause decreased vision or even lead to permanent blindness. Drusen is an important clinical indicator for AMD which can help doctor diagnose disease and decide the strategy of treatment. Optical Coherence Tomography (OCT) is widely used in the diagnosis of ophthalmic diseases, include AMD. In this paper, we propose a classification method based on Multiple Instance Learning (MIL) to detect AMD. Drusen can exist in a few slices of OCT images, and MIL is utilized in our method. We divided the method into two phases: training phase and testing phase. We train the initial features and clustered to create a codebook, and employ the trained classifier in the test set. Experiment results show that our method achieved high accuracy and effectiveness.

    An 18-year-old girl presented with multiple itchy hyperpigmented papules and plaques, along with tense blisters over the lower limbs and buttocks for last 3 months. These papules, plaques, and bullae were mostly localized to preexisting scars. The histopathological findings from papule and bulla were consistent with lichen planus (LP) and bullous pemphigoid, respectively. Direct immunofluorescence (DIF) of perilesional skin around bulla showed linear deposition of IgG and C3. Considering clinical, histopathological and DIF findings, diagnosis of LP pemphigoides (LPP) was made. The preferential localization of LPP lesions over preexisting scars was a very interesting finding in our case an extremely rare instance of the isotopic phenomenon. PMID:26677275

    2011-01-01

    New generations of surveillance drones are being outfitted with numerous high definition cameras. The rapid proliferation of fielded sensors and supporting capacity for processing and displaying data will translate into ever more capable platforms, but with increased capability comes increased complexity and scale that may diminish the usefulness of such platforms to human operators. We investigate methods for alleviating strain on analysts by automatically retrieving content specific to their current task using a machine learning technique known as Multi-Instance Learning (MIL). We use MIL to create a real time model of the analysts' task and subsequently use the model to dynamically retrieve relevant content. This paper presents results from a pilot experiment in which a computer agent is assigned analyst tasks such as identifying caravanning vehicles in a simulated vehicle traffic environment. We compare agent performance between MIL aided trials and unaided trials.

    2013-02-01

    Diabetic retinopathy (DR) is a vision-threatening complication from diabetes mellitus, a medical condition that is rising globally. Unfortunately, many patients are unaware of this complication because of absence of symptoms. Regular screening of DR is necessary to detect the condition for timely treatment. Content-based image retrieval, using archived and diagnosed fundus (retinal) camera DR images can improve screening efficiency of DR. This content-based image retrieval study focuses on two DR clinical findings, microaneurysm and neovascularization, which are clinical signs of non-proliferative and proliferative diabetic retinopathy. The authors propose a multi-class multiple-instance image retrieval framework which deploys a modified color correlogram and statistics of steerable Gaussian Filter responses, for retrieving clinically relevant images from a database of DR fundus image database.

    2017-07-01

    Automatic detection of abnormal cells from cervical smear images is extremely demanded in annual diagnosis of women's cervical cancer. For this medical cell recognition problem, there are three different feature sections, namely cytology morphology, nuclear chromatin pathology and region intensity. The challenges of this problem come from feature combination s and classification accurately and efficiently. Thus, we propose an efficient abnormal cervical cell detection system based on multi-instance extreme learning machine (MI-ELM) to deal with above two questions in one unified framework. MI-ELM is one of the most promising supervised learning classifiers which can deal with several feature sections and realistic classification problems analytically. Experiment results over Herlev dataset demonstrate that the proposed method outperforms three traditional methods for two-class classification in terms of well accuracy and less time.

    Digitization of full biopsy slides using the whole slide imaging technology has provided new opportunities for understanding the diagnostic process of pathologists and developing more accurate computer aided diagnosis systems. However, the whole slide images also provide two new challenges to image analysis algorithms. The first one is the need for simultaneous localization and classification of malignant areas in these large images, as different parts of the image may have different levels of diagnostic relevance. The second challenge is the uncertainty regarding the correspondence between the particular image areas and the diagnostic labels typically provided by the pathologists at the slide level. In this paper, we exploit a data set that consists of recorded actions of pathologists while they were interpreting whole slide images of breast biopsies to find solutions to these challenges. First, we extract candidate regions of interest (ROI) from the logs of pathologists' image screenings based on different actions corresponding to zoom events, panning motions, and fixations. Then, we model these ROIs using color and texture features. Next, we represent each slide as a bag of instances corresponding to the collection of candidate ROIs and a set of slide-level labels extracted from the forms that the pathologists filled out according to what they saw during their screenings. Finally, we build classifiers using five different multi-instance multi-label learning algorithms, and evaluate their performances under different learning and validation scenarios involving various combinations of data from three expert pathologists. Experiments that compared the slide-level predictions of the classifiers with the reference data showed average precision values up to 62% when the training and validation data came from the same individual pathologist's viewing logs, and an average precision of 64% was obtained when the candidate ROIs and the labels from all pathologists were

  12. Stochastic learning of multi-instance dictionary for earth mover’s distance-based histogram comparison

    KAUST Repository

    Fan, Jihong

    2016-09-17

    Dictionary plays an important role in multi-instance data representation. It maps bags of instances to histograms. Earth mover’s distance (EMD) is the most effective histogram distance metric for the application of multi-instance retrieval. However, up to now, there is no existing multi-instance dictionary learning methods designed for EMD-based histogram comparison. To fill this gap, we develop the first EMD-optimal dictionary learning method using stochastic optimization method. In the stochastic learning framework, we have one triplet of bags, including one basic bag, one positive bag, and one negative bag. These bags are mapped to histograms using a multi-instance dictionary. We argue that the EMD between the basic histogram and the positive histogram should be smaller than that between the basic histogram and the negative histogram. Base on this condition, we design a hinge loss. By minimizing this hinge loss and some regularization terms of the dictionary, we update the dictionary instances. The experiments over multi-instance retrieval applications shows its effectiveness when compared to other dictionary learning methods over the problems of medical image retrieval and natural language relation classification. © 2016 The Natural Computing Applications Forum

  13. Astronomical knowledge transmission through illustrated Aratea manuscripts

    Dolan, Marion

    2017-01-01

    This carefully researched monograph is a historical investigation of the illustrated Aratea astronomical manuscript and its many interpretations over the centuries. Aratus' 270 B.C.E. Greek poem describing the constellations and astrological phenomena was translated and copied over 800 years into illuminated manuscripts that preserved and illustrated these ancient stories about the constellations. The Aratea survives in its entirety due to multiple translations from Greek to Latin and even to Arabic, with many illuminated versions being commissioned over the ages. The survey encompasses four interrelated disciplines: history of literature, history of myth, history of science, and history of art. Aratea manuscripts by their nature are a meeting place of these distinct branches, and the culling of information from historical literature and from the manuscripts themselves focuses on a wider, holistic view; a narrow approach could not provide a proper prospective. What is most essential to know about this work is...

  14. Mechanisms in ancient Chinese books with illustrations

    2014-01-01

    This book presents a unique approach for studying mechanisms and machines with drawings that were depicted unclearly in ancient Chinese books. The historical, cultural and technical backgrounds of the mechanisms are explained, and various mechanisms described and illustrated in ancient books are introduced. By utilizing the idea for the conceptual design of modern mechanisms, all feasible designs of ancient mechanisms with uncertain members and joints that meet the technical standards of the subjects’ time periods are synthesized systematically. Ancient Chinese crossbows (the original crossbow and repeating crossbows), textile mechanisms (silk-reeling mechanism, spinning mechanisms, and looms), and many other artisan's tool mechanisms are used as illustrated examples.  Such an approach provides a logical method for the reconstruction designs of ancient mechanisms with uncertain structures. It also provides an innovative direction for researchers to further identify the original structures of mechanisms...

  15. Selling pictures: the illustrated auction catalogue

    2014-12-01

    Full Text Available This essay is based upon a survey of reproductions in auction catalogues – from their first appearance in the early eighteenth century until their more consistent use in the second decade of the twentieth century. Examining the role of these illustrations sheds light on how auctions functioned; it was not just the works of art that were traded, but knowledge about those works of art became currency to be exchanged. In contrast to the high end engravings and photographs of luxury illustrated art books, reproductions in auction catalogues – publications produced as ephemeral marketing tools – were of noticeably lower quality. This study of the status of reproductions, therefore, investigates the evolving understanding of art knowledge, both aesthetic and economic, and the interdependence of the market and connoisseurship.

    Tattoos, and tattoo complications as well, are colorful and visually flashy. A clinical outlook provides important clues to diagnosis by pattern recognition. This atlas,which is a report of 79 case illustrations, is made as a practical tool and vade mecum for the clinician. The atlas can be used in the office and as a bedside tool. It includes characteristic photos, and each case is accompanied with a brief medical history, a comment with learning points, the final diagnosis, and a review of therapeutic options. This spectrum of cases illustrates the different diagnostic entities according to the newly proposed Bispebjerg University Hospital ('Tattoo Clinic') diagnostic system of tattoo complications, a system reported to the 11th revision of the WHO disease classification system. Cases include allergies predominantly seen in red tattoos manifesting the characteristic patterns of plaque elevation, excessive hyperkeratosis, ulcerating reactions, urticaria, and generalized skin rash. Each type of reaction has typical clues to diagnosis and a typical disease course. 'Cross-sensitivity' allergic reactions in old tattoos of the same color as the trigger tattoo are also illustrated. Reactions in black tattoos are dominated by a pattern with papulonodular reactions, which are nonallergic anddue to pigment agglomeration in the skin. Reactions may be granulomatous and a marker of systemic sarcoidosis, sometimes associated with a general outbreak in the skin in black tattoos, e.g. 'rush phenomenon'. Bacterial infections are also illustrated. The technical hazards of tattooing and sequels as well as unwanted effects of tattoo removal by lasers are shown along with severe scarring following tattoo removal by caustics. This atlas is a tutorial in modern medical and surgical treatments of tattoo complications. © 2017 S. Karger AG, Basel.

The artistic focus was on works by 15 artists born in the late 19th century, mainly from Croatia. One exhibit was an exception, however since it comes from my own collection, the edition of Kadar jaz, dekle, umrla bom (When I, a girl, will die, a collection of folk songs arranged for a mixed choir by the Slovenian composer Breda Šček (1893–1968, published in Trieste in 1933. The cover illustration was made by Anton (Tone Kralj (1900–1975, the Slovenian painter, graphic artist and sculptor, who probably met the composer Šček at the beginning of the 1930s. In the period from 1932 to 1954, Kralj made illustrations for 27 scores by seven Slovenian composers: Lojze Bratuž, Ivan Laharnar, Silvester Orel, Stanko Premrl, Breda Šček, Matija Tomc and Vinko Vodopivec. These composers were linked not only by Kralj’s contributions to their scores, but also by their engagement in church music, and most were from the same region of Slovenia, Primorska.

    2003-12-01

    While the psychological literature shows that perceptions of uncontrollability contribute to anxiety and other pathologies, interventions that enhance perceived control have been shown to reduce anxiety. This study attempted to assess a brief videotape to enhance child perceived control in a dental setting. 101 children aged 7-9 years completed warm-up procedures and viewed either: a) the experimental intervention, a 2 minutes video of a dentist explaining what an injection will feel like and proposing hand raising as a signal mechanism; or b) the control condition, a 2 minutes video of Disneyland. Fear of dental injections was assessed on a 10 cm visual analogue scale before and after the intervention. In the experimental group there was a significant fear reduction from pre- to post-intervention, while this was not the case in the control group. Children with higher pre-existing levels of fear benefited more from the intervention than children with lower levels of fear. The results of this pilot study suggest that intervention packages that impact child control have promise in lowering anxiety.

    Full Text Available Objective. The purpose of this study was to examine how patient, physician, and situational factors are associated with the extent to which providers educate patients about glaucoma and glaucoma medications, and which patient and provider characteristics are associated with whether providers educate patients about glaucoma and glaucoma medications. Methods. Patients with glaucoma who were newly prescribed or on glaucoma medications were recruited and a cross-sectional study was conducted at six ophthalmology clinics. Patients’ visits were videotape recorded and patients were interviewed after visits. Generalized estimating equations were used to analyze the data. Results. Two hundred and seventy-nine patients participated. Providers were significantly more likely to educate patients about glaucoma and glaucoma medications if they were newly prescribed glaucoma medications. Providers were significantly less likely to educate African American patients about glaucoma. Providers were significantly less likely to educate patients of lower health literacy about glaucoma medications. Conclusion. Eye care providers did not always educate patients about glaucoma or glaucoma medications. Practice Implications. Providers should consider educating more patients about what glaucoma is and how it is treated so that glaucoma patients can better understand their disease. Even if a patient has already been educated once, it is important to reinforce what has been taught before.

    The NASA developed Ares rockets, named for the Greek god associated with Mars, will return humans to the moon and later take them to Mars and other destinations. In this early illustration, the Ares I is illustrated during lift off. Ares I is an inline, two-stage rocket configuration topped by the Orion crew vehicle and its launch abort system. With a primary mission of carrying four to six member crews to Earth orbit, Ares I may also use its 25-ton payload capacity to deliver resources and supplies to the International Space Station (ISS), or to 'park' payloads in orbit for retrieval by other spacecraft bound for the moon or other destinations. Ares I uses a single five-segment solid rocket booster, a derivative of the space shuttle solid rocket booster, for the first stage. A liquid oxygen/liquid hydrogen J-2X engine, derived from the J-2 engine used on the second stage of the Apollo vehicle, will power the Ares I second stage. Ares I can lift more than 55,000 pounds to low Earth orbit. The Ares I is subject to configuration changes before it is actually launched. This illustration reflects the latest configuration as of September 2006.

  17. How to Mine Information from Each Instance to Extract an Abbreviated and Credible Logical Rule

    Full Text Available Decision trees are particularly promising in symbolic representation and reasoning due to their comprehensible nature, which resembles the hierarchical process of human decision making. However, their drawbacks, caused by the single-tree structure,cannot be ignored. A rigid decision path may cause the majority class to overwhelm otherclass when dealing with imbalanced data sets, and pruning removes not only superfluousnodes, but also subtrees. The proposed learning algorithm, flexible hybrid decision forest(FHDF, mines information implicated in each instance to form logical rules on the basis of a chain rule of local mutual information, then forms different decision tree structures and decision forests later. The most credible decision path from the decision forest can be selected to make a prediction. Furthermore, functional dependencies (FDs, which are extracted from the whole data set based on association rule analysis, perform embedded attribute selection to remove nodes rather than subtrees, thus helping to achieve different levels of knowledge representation and improve model comprehension in the framework of semi-supervised learning. Naive Bayes replaces the leaf nodes at the bottom of the tree hierarchy, where the conditional independence assumption may hold. This technique reduces the potential for overfitting and overtraining and improves the prediction quality and generalization. Experimental results on UCI data sets demonstrate the efficacy of the proposed approach.

    Decision trees are renowned in the computational chemistry and machine learning communities for their interpretability. Their capacity and usage are somewhat limited by the fact that they normally work on categorical data. Improvements to known decision tree algorithms are usually carried out by increasing and tweaking parameters, as well as the post-processing of the class assignment. In this work we attempted to tackle both these issues. Firstly, conditional mutual information was used as the criterion for selecting the attribute on which to split instances. The algorithm performance was compared with the results of C4.5 (WEKA's J48) using default parameters and no restrictions. Two datasets were used for this purpose, DrugBank compounds for HRH1 binding prediction and Traditional Chinese Medicine formulation predicted bioactivities for therapeutic class annotation. Secondly, an automated binning method for continuous data was evaluated, namely Scott's normal reference rule, in order to allow any decision tree to easily handle continuous data. This was applied to all approved drugs in DrugBank for predicting the RDKit SLogP property, using the remaining RDKit physicochemical attributes as input.

    Horror content sharing on the Web is a growing phenomenon that can interfere with our daily life and affect the mental health of those involved. As an important form of expression, horror images have their own characteristics that can evoke extreme emotions. In this paper, we present a novel context-aware multi-instance learning (CMIL) algorithm for horror image recognition. The CMIL algorithm identifies horror images and picks out the regions that cause the sensation of horror in these horror images. It obtains contextual cues among adjacent regions in an image using a random walk on a contextual graph. Borrowing the strength of the fuzzy support vector machine (FSVM), we define a heuristic optimization procedure based on the FSVM to search for the optimal classifier for the CMIL. To improve the initialization of the CMIL, we propose a novel visual saliency model based on the tensor analysis. The average saliency value of each segmented region is set as its initial fuzzy membership in the CMIL. The advantage of the tensor-based visual saliency model is that it not only adaptively selects features, but also dynamically determines fusion weights for saliency value combination from different feature subspaces. The effectiveness of the proposed CMIL model is demonstrated by its use in horror image recognition on two large-scale image sets collected from the Internet.

    In conventional Magnetic Resonance (MR) image based methods, two stages are often involved to capture brain structural information for disease diagnosis, i.e., 1) manually partitioning each MR image into a number of regions-of-interest (ROIs), and 2) extracting pre-defined features from each ROI for diagnosis with a certain classifier. However, these pre-defined features often limit the performance of the diagnosis, due to challenges in 1) defining the ROIs and 2) extracting effective disease-related features. In this paper, we propose a landmark-based deep multi-instance learning (LDMIL) framework for brain disease diagnosis. Specifically, we first adopt a data-driven learning approach to discover disease-related anatomical landmarks in the brain MR images, along with their nearby image patches. Then, our LDMIL framework learns an end-to-end MR image classifier for capturing both the local structural information conveyed by image patches located by landmarks and the global structural information derived from all detected landmarks. We have evaluated our proposed framework on 1526 subjects from three public datasets (i.e., ADNI-1, ADNI-2, and MIRIAD), and the experimental results show that our framework can achieve superior performance over state-of-the-art approaches.

    Automated annotation of protein function is challenging. As the number of sequenced genomes rapidly grows, the vast majority of proteins can only be annotated computationally. Nature often brings several domains together to form multi-domain and multi-functional proteins with a vast number of possibilities, and each domain may fulfill its own function independently or in a concerted manner with its neighbors. Thus, it is evident that the protein function prediction problem is naturally and inherently Multi-Instance Multi-Label (MIML) learning tasks. Based on the state-of-the-art MIML algorithm MIMLNN, we propose a novel ensemble MIML learning framework EnMIMLNN and design three algorithms for this task by combining the advantage of three kinds of Hausdorff distance metrics. Experiments on seven real-world organisms covering the biological three-domain system, i.e., archaea, bacteria, and eukaryote, show that the EnMIMLNN algorithms are superior to most state-of-the-art MIML and Multi-Label learning algorithms.

    Full Text Available Computational models of cognition provide an interface to connect advanced mathematical tools and methods to empirically supported theories of behavior in psychology, cognitive science, and neuroscience. In this article, we consider a computational model of instance-based learning, implemented in the ACT-R cognitive architecture. We propose an approach for obtaining mathematical reformulations of such cognitive models that improve their computational tractability. For the well-established Sugar Factory dynamic decision making task, we conduct a simulation study to analyze central model parameters. We show how mathematical optimization techniques can be applied to efficiently identify optimal parameter values with respect to different optimization goals. Beyond these methodological contributions, our analysis reveals the sensitivity of this particular task with respect to initial settings and yields new insights into how average human performance deviates from potential optimal performance. We conclude by discussing possible extensions of our approach as well as future steps towards applying more powerful derivative-based optimization methods.

    A non-parametric method is applied to quantify residual uncertainty in hydrologic streamflow forecasting. This method acts as a post-processor on deterministic model forecasts and generates a residual uncertainty distribution. Based on instance-based learning, it uses a k nearest-neighbour search for similar historical hydrometeorological conditions to determine uncertainty intervals from a set of historical errors, i.e. discrepancies between past forecast and observation. The performance of this method is assessed using test cases of hydrologic forecasting in two UK rivers: the Severn and Brue. Forecasts in retrospect were made and their uncertainties were estimated using kNN resampling and two alternative uncertainty estimators: quantile regression (QR) and uncertainty estimation based on local errors and clustering (UNEEC). Results show that kNN uncertainty estimation produces accurate and narrow uncertainty intervals with good probability coverage. Analysis also shows that the performance of this technique depends on the choice of search space. Nevertheless, the accuracy and reliability of uncertainty intervals generated using kNN resampling are at least comparable to those produced by QR and UNEEC. It is concluded that kNN uncertainty estimation is an interesting alternative to other post-processors, like QR and UNEEC, for estimating forecast uncertainty. Apart from its concept being simple and well understood, an advantage of this method is that it is relatively easy to implement.

    Finding conserved motifs in genomic sequences represents one of essential bioinformatic problems. However, achieving high discovery performance without imposing substantial auxiliary constraints on possible motif features remains a key algorithmic challenge. This work describes BAMBI-a sequential Monte Carlo motif-identification algorithm, which is based on a position weight matrix model that does not require additional constraints and is able to estimate such motif properties as length, logo, number of instances and their locations solely on the basis of primary nucleotide sequence data. Furthermore, should biologically meaningful information about motif attributes be available, BAMBI takes advantage of this knowledge to further refine the discovery results. In practical applications, we show that the proposed approach can be used to find sites of such diverse DNA-binding molecules as the cAMP receptor protein (CRP) and Din-family site-specific serine recombinases. Results obtained by BAMBI in these and other settings demonstrate better statistical performance than any of the four widely-used profile-based motif discovery methods: MEME, BioProspector with BioOptimizer, SeSiMCMC and Motif Sampler as measured by the nucleotide-level correlation coefficient. Additionally, in the case of Din-family recombinase target site discovery, the BAMBI-inferred motif is found to be the only one functionally accurate from the underlying biochemical mechanism standpoint. C++ and Matlab code is available at http://www.ee.columbia.edu/~guido/BAMBI or http://genomics.lbl.gov/BAMBI/.

  5. A Fisher Kernel Approach for Multiple Instance Based Object Retrieval in Video Surveillance

    MIRONICA, I.

    2015-11-01

    Full Text Available This paper presents an automated surveillance system that exploits the Fisher Kernel representation in the context of multiple-instance object retrieval task. The proposed algorithm has the main purpose of tracking a list of persons in several video sources, using only few training examples. In the first step, the Fisher Kernel representation describes a set of features as the derivative with respect to the log-likelihood of the generative probability distribution that models the feature distribution. Then, we learn the generative probability distribution over all features extracted from a reduced set of relevant frames. The proposed approach shows significant improvements and we demonstrate that Fisher kernels are well suited for this task. We demonstrate the generality of our approach in terms of features by conducting an extensive evaluation with a broad range of keypoints features. Also, we evaluate our method on two standard video surveillance datasets attaining superior results comparing to state-of-the-art object recognition algorithms.

    Full Text Available Nature often brings several domains together to form multidomain and multifunctional proteins with a vast number of possibilities. In our previous study, we disclosed that the protein function prediction problem is naturally and inherently Multi-Instance Multilabel (MIML learning tasks. Automated protein function prediction is typically implemented under the assumption that the functions of labeled proteins are complete; that is, there are no missing labels. In contrast, in practice just a subset of the functions of a protein are known, and whether this protein has other functions is unknown. It is evident that protein function prediction tasks suffer from weak-label problem; thus protein function prediction with incomplete annotation matches well with the MIML with weak-label learning framework. In this paper, we have applied the state-of-the-art MIML with weak-label learning algorithm MIMLwel for predicting protein functions in two typical real-world electricigens organisms which have been widely used in microbial fuel cells (MFCs researches. Our experimental results validate the effectiveness of MIMLwel algorithm in predicting protein functions with incomplete annotation.

  8. Instance-based Policy Learning by Real-coded Genetic Algorithms and Its Application to Control of Nonholonomic Systems

    Miyamae, Atsushi; Sakuma, Jun; Ono, Isao; Kobayashi, Shigenobu

    The stabilization control of nonholonomic systems have been extensively studied because it is essential for nonholonomic robot control problems. The difficulty in this problem is that the theoretical derivation of control policy is not necessarily guaranteed achievable. In this paper, we present a reinforcement learning (RL) method with instance-based policy (IBP) representation, in which control policies for this class are optimized with respect to user-defined cost functions. Direct policy search (DPS) is an approach for RL; the policy is represented by parametric models and the model parameters are directly searched by optimization techniques including genetic algorithms (GAs). In IBP representation an instance consists of a state and an action pair; a policy consists of a set of instances. Several DPSs with IBP have been previously proposed. In these methods, sometimes fail to obtain optimal control policies when state-action variables are continuous. In this paper, we present a real-coded GA for DPSs with IBP. Our method is specifically designed for continuous domains. Optimization of IBP has three difficulties; high-dimensionality, epistasis, and multi-modality. Our solution is designed for overcoming these difficulties. The policy search with IBP representation appears to be high-dimensional optimization; however, instances which can improve the fitness are often limited to active instances (instances used for the evaluation). In fact, the number of active instances is small. Therefore, we treat the search problem as a low dimensional problem by restricting search variables only to active instances. It has been commonly known that functions with epistasis can be efficiently optimized with crossovers which satisfy the inheritance of statistics. For efficient search of IBP, we propose extended crossover-like mutation (extended XLM) which generates a new instance around an instance with satisfying the inheritance of statistics. For overcoming multi-modality, we

To enable local extraction of smooth flow field quantities especially on rather short time scales, sampling over an ensemble of molecular dynamics simulations is introduced. We provide details on these extensions including the transient coupling algorithm, open boundary forcing, and multi-instance sampling. Furthermore, we validate the coupling in Couette flow using different particle simulation software packages and particle models, i.e. molecular dynamics and dissipative particle dynamics. Finally, we demonstrate the parallel scalability of the molecular-continuum simulations by using up to 65 536 compute cores of the supercomputer Shaheen II located at KAUST.

    Full Text Available Introduction: Medical student should be trained in medical ethics and one of the most essential issues in this field is taking informed consents. In this research, we compared the effect of effectiveness of teaching methods on students’ ability in taking informed consent from patients. Methods: This semi-experimental study was carried out on fifty eight subjects from the 4th-year students of Shiraz University of Medical Sciences who attended in medical ethics course before their ‘clinical clerkship’training.Method of sampling was census and students were randomly allocated into two groups of control group (n=28 was trained in traditional lecture-based class and the case groupnamed as A1 (n=22 were taught by video-taped examples of standardized patient.Then A1 group attended in traditional lecture-based classes named as A2. The groups were evaluated in terms the ability of recognition of ethical issues through the scenario based ethical examination before and after each training. Scenarios were related to the topics of informed consent. Data were analyzed by SPSS 14 software using descriptive statistics and anova test. P-value less than 0.05 was considered as significant. Results: The mean scores results of A2, A1 and B group were found to be 7.21, 5.91 and 5.73 out of 8, respectively. Comparison between the groups demonstrated that the ability of taking informed consent was significantly higher in A2 group (p<0.001, followed by A1 group (p<0.05, while was the least in the B group (p=0.875. Conclusion: According to this research, lecture-based teaching is still of great value in teaching medical ethics, but when combined with standardized patient, the outcome will be much better. It should be considered that mixed methods of teaching should be used together for better result.

    To determine the effects of an adversary's behavior on the defender's accurate and timely detection of network threats. Cyber attacks cause major work disruption. It is important to understand how a defender's behavior (experience and tolerance to threats), as well as adversarial behavior (attack strategy), might impact the detection of threats. In this article, we use cognitive modeling to make predictions regarding these factors. Different model types representing a defender, based on Instance-Based Learning Theory (IBLT), faced different adversarial behaviors. A defender's model was defined by experience of threats: threat-prone (90% threats and 10% nonthreats) and nonthreat-prone (10% threats and 90% nonthreats); and different tolerance levels to threats: risk-averse (model declares a cyber attack after perceiving one threat out of eight total) and risk-seeking (model declares a cyber attack after perceiving seven threats out of eight total). Adversarial behavior is simulated by considering different attack strategies: patient (threats occur late) and impatient (threats occur early). For an impatient strategy, risk-averse models with threat-prone experiences show improved detection compared with risk-seeking models with nonthreat-prone experiences; however, the same is not true for a patient strategy. Based upon model predictions, a defender's prior threat experiences and his or her tolerance to threats are likely to predict detection accuracy; but considering the nature of adversarial behavior is also important. Decision-support tools that consider the role of a defender's experience and tolerance to threats along with the nature of adversarial behavior are likely to improve a defender's overall threat detection.

  13. Salience Assignment for Multiple-Instance Data and Its Application to Crop Yield Prediction

    Wagstaff, Kiri L.; Lane, Terran

    2010-01-01

    An algorithm was developed to generate crop yield predictions from orbital remote sensing observations, by analyzing thousands of pixels per county and the associated historical crop yield data for those counties. The algorithm determines which pixels contain which crop. Since each known yield value is associated with thousands of individual pixels, this is a multiple instance learning problem. Because individual crop growth is related to the resulting yield, this relationship has been leveraged to identify pixels that are individually related to corn, wheat, cotton, and soybean yield. Those that have the strongest relationship to a given crop s yield values are most likely to contain fields with that crop. Remote sensing time series data (a new observation every 8 days) was examined for each pixel, which contains information for that pixel s growth curve, peak greenness, and other relevant features. An alternating-projection (AP) technique was used to first estimate the "salience" of each pixel, with respect to the given target (crop yield), and then those estimates were used to build a regression model that relates input data (remote sensing observations) to the target. This is achieved by constructing an exemplar for each crop in each county that is a weighted average of all the pixels within the county; the pixels are weighted according to the salience values. The new regression model estimate then informs the next estimate of the salience values. By iterating between these two steps, the algorithm converges to a stable estimate of both the salience of each pixel and the regression model. The salience values indicate which pixels are most relevant to each crop under consideration.

    2002-04-01

    The goal of this research was to study how different groups of child welfare professionals prioritize and use information to make placement decisions following instances of child abuse. A total of 90 juvenile court judges and guardians ad litem, Court Appointed Special Advocates (CASA), social workers, and mental health professionals responded to a detailed questionnaire describing four case studies of child physical abuse in which a parent was the perpetrator, the child was either 2 years or 6 years of age, and the abuse was either first time or chronic. Participants rated the impact of specific pieces of information regarding child, family, and system-level characteristics on their decision-making process. Analyses of reactions to these vignettes demonstrate that professional groups use different kinds of information when making decisions about foster care placements. Social workers and mental health providers rely on information about the severity and pattern of abuse and on information about services offered in the past and parental responses to those services. Judges and guardians ad litem rely more heavily on information about the likelihood of a reoccurrence of abuse and the child's ability to recount the abuse, whereas CASA volunteers rely on information about the stability of the family. Professional group membership, rather than factors such as age or ethnicity of the child or chronicity of abuse, accounts for different patterns of prioritizing and using information when making decisions about whether a child should remain in the home or be placed in foster care. The implications for community-based training and intervention efforts are discussed.

  15. Multiple Objects Fusion Tracker Using a Matching Network for Adaptively Represented Instance Pairs.

    Oh, Sang-Il; Kang, Hang-Bong

    2017-04-18

    Multiple-object tracking is affected by various sources of distortion, such as occlusion, illumination variations and motion changes. Overcoming these distortions by tracking on RGB frames, such as shifting, has limitations because of material distortions caused by RGB frames. To overcome these distortions, we propose a multiple-object fusion tracker (MOFT), which uses a combination of 3D point clouds and corresponding RGB frames. The MOFT uses a matching function initialized on large-scale external sequences to determine which candidates in the current frame match with the target object in the previous frame. After conducting tracking on a few frames, the initialized matching function is fine-tuned according to the appearance models of target objects. The fine-tuning process of the matching function is constructed as a structured form with diverse matching function branches. In general multiple object tracking situations, scale variations for a scene occur depending on the distance between the target objects and the sensors. If the target objects in various scales are equally represented with the same strategy, information losses will occur for any representation of the target objects. In this paper, the output map of the convolutional layer obtained from a pre-trained convolutional neural network is used to adaptively represent instances without information loss. In addition, MOFT fuses the tracking results obtained from each modality at the decision level to compensate the tracking failures of each modality using basic belief assignment, rather than fusing modalities by selectively using the features of each modality. Experimental results indicate that the proposed tracker provides state-of-the-art performance considering multiple objects tracking (MOT) and KITTIbenchmarks.

    2001-03-01

    The study investigated the sensitivity of the instance-based- learning (IBL) driven multi-source information fusion process to the underlying distance metric. An audio-visual system for recognition of spoken French vowels is used as an example for this investigation. Three different distance measures, namely, Euclidian, city block and chess board metrics, are employed for this initial foray into metric sensitivity analysis. In this example, the test phase encompasses a broader range of noise environments of the audio signal as compared to the training phase. The system is thus exercised in both trained and untrained noise regimes. Under the untrained regime, interpolation as well as extrapolation or off-nominal scenarios are considered. In the former, the signal to noise ratio in the test phase is within the range used in training phase but does not specifically include it. In the latter, the signal to noise ratio in the test phase is outside the range used in the training phase. It is observed that while both of the single-sensor based decision systems individually are not very sensitive to the choice of the metric, the fused decision system is indeed significantly more sensitive to this choice. The city block metric offers better performance as compared to the other two in the case of the fused audio- visual system across most of the spectrum of noise environments, except for the extreme off-nominal conditions wherein the Euclidian offers slightly better performance. The chess board metric offers the lowest performance across the entire test range. The lack of training in the interpolation scenario has a noticeably strong effect on audio performance under the chess board metric.

  17. DCAN: Deep contour-aware networks for object instance segmentation from histology images.

    In histopathological image analysis, the morphology of histological structures, such as glands and nuclei, has been routinely adopted by pathologists to assess the malignancy degree of adenocarcinomas. Accurate detection and segmentation of these objects of interest from histology images is an essential prerequisite to obtain reliable morphological statistics for quantitative diagnosis. While manual annotation is error-prone, time-consuming and operator-dependant, automated detection and segmentation of objects of interest from histology images can be very challenging due to the large appearance variation, existence of strong mimics, and serious degeneration of histological structures. In order to meet these challenges, we propose a novel deep contour-aware network (DCAN) under a unified multi-task learning framework for more accurate detection and segmentation. In the proposed network, multi-level contextual features are explored based on an end-to-end fully convolutional network (FCN) to deal with the large appearance variation. We further propose to employ an auxiliary supervision mechanism to overcome the problem of vanishing gradients when training such a deep network. More importantly, our network can not only output accurate probability maps of histological objects, but also depict clear contours simultaneously for separating clustered object instances, which further boosts the segmentation performance. Our method ranked the first in two histological object segmentation challenges, including 2015 MICCAI Gland Segmentation Challenge and 2015 MICCAI Nuclei Segmentation Challenge. Extensive experiments on these two challenging datasets demonstrate the superior performance of our method, surpassing all the other methods by a significant margin. Copyright © 2016 Elsevier B.V.

  18. Multiple Objects Fusion Tracker Using a Matching Network for Adaptively Represented Instance Pairs

    2017-04-01

    Full Text Available Multiple-object tracking is affected by various sources of distortion, such as occlusion, illumination variations and motion changes. Overcoming these distortions by tracking on RGB frames, such as shifting, has limitations because of material distortions caused by RGB frames. To overcome these distortions, we propose a multiple-object fusion tracker (MOFT, which uses a combination of 3D point clouds and corresponding RGB frames. The MOFT uses a matching function initialized on large-scale external sequences to determine which candidates in the current frame match with the target object in the previous frame. After conducting tracking on a few frames, the initialized matching function is fine-tuned according to the appearance models of target objects. The fine-tuning process of the matching function is constructed as a structured form with diverse matching function branches. In general multiple object tracking situations, scale variations for a scene occur depending on the distance between the target objects and the sensors. If the target objects in various scales are equally represented with the same strategy, information losses will occur for any representation of the target objects. In this paper, the output map of the convolutional layer obtained from a pre-trained convolutional neural network is used to adaptively represent instances without information loss. In addition, MOFT fuses the tracking results obtained from each modality at the decision level to compensate the tracking failures of each modality using basic belief assignment, rather than fusing modalities by selectively using the features of each modality. Experimental results indicate that the proposed tracker provides state-of-the-art performance considering multiple objects tracking (MOT and KITTIbenchmarks.

  19. Synthesis of electromagnetic metasurfaces: principles and illustrations

    2015-01-01

    Full Text Available The paper presents partial overview of the mathematical synthesis and the physical realization of metasurfaces, and related illustrative examples. The synthesis consists in determining the exact tensorial surface susceptibility functions of the metasurface, based on generalized sheet transition conditions, while the realization deals with both metallic and dielectric scattering particle structures. The examples demonstrate the capabilities of the synthesis and realization techniques, thereby showing the plethora of possible metasurface field transmission and subsequent applications. The first example is the design of two diffraction engineering birefringent metasurfaces performing polarization beam splitting and orbital angular momentum multiplexing, respectively. Next, we discuss the concept of the electromagnetic remotely controlled metasurface spatial processor, which is an electromagnetic linear switch based on destructive interferences. Then, we introduce a non-reciprocal non-gyrotropic metasurface using a pick-up circuit radiator (PCR architecture. Finally, the implementation of all-dielectric metasurfaces for frequency dispersion engineering is discussed.

  20. Illustrating the disassembly of 3D models

    2013-10-01

    We present a framework for the automatic disassembly of 3D man-made models and the illustration of the disassembly process. Given an assembled 3D model, we first analyze the individual parts using sharp edge loops and extract the contact faces between each pair of neighboring parts. The contact faces are then used to compute the possible moving directions of each part. We then present a simple algorithm for clustering the sets of the individual parts into meaningful sub-assemblies, which can be used for a hierarchical decomposition. We take the stability of sub-assemblies into account during the decomposition process by considering the upright orientation of the input models. Our framework also provides a user-friendly interface to enable the superimposition of the constraints for the decomposition. Finally, we visualize the disassembly process by generating an animated sequence. The experiments demonstrate that our framework works well for a variety of complex models. © 2013 Elsevier Ltd.

    Fundamental concepts in statistics form the cornerstone of scientific inquiry. If we fail to understand fully these fundamental concepts, then the scientific conclusions we reach are more likely to be wrong. This is more than supposition: for 60 years, statisticians have warned that the scientific literature harbors misunderstandings about basic statistical concepts. Original articles published in 1996 by the American Physiological Society's journals fared no better in their handling of basic statistical concepts. In this review, we summarize the two main scientific uses of statistics: hypothesis testing and estimation. Most scientists use statistics solely for hypothesis testing; often, however, estimation is more useful. We also illustrate the concepts of variability and uncertainty, and we demonstrate the essential distinction between statistical significance and scientific importance. An understanding of concepts such as variability, uncertainty, and significance is necessary, but it is not sufficient; we show also that the numerical results of statistical analyses have limitations.

    Stimulus-response (S-R) associations, the basis of learning and behavioral automaticity, are formed by the (repeated) co-occurrence of stimuli and responses and render stimuli able to automatically trigger associated responses. The strength and behavioral impact of these S-R associations increases with the number of priming instances (i.e., practice). Here we investigated whether multiple priming instances of a special form of instruction, verbal coding, also lead to the formation of stronger S-R associations in comparison to a single instance of priming. Participants either actively classified stimuli or passively attended to verbal codes denoting responses once or four times before S-R associations were probed. We found that whereas S-R associations formed on the basis of active task execution (i.e., practice) were strengthened by multiple priming instances, S-R associations formed on the basis of verbal codes (i.e., instruction) did not benefit from additional priming instances. These findings indicate difference in the mechanisms underlying the encoding and/or retrieval of previously executed and verbally coded S-R associations. Copyright © 2017 Elsevier B.V.

    Understanding the mechanism of transcriptional regulation remains an inspiring stage of molecular biology. Recently, in vitro protein-binding microarray experiments have greatly improved the understanding of transcription factor-DNA interaction. We present a method - MIL3D - which predicts in vitro transcription factor binding by multiple-instance learning with structural properties of DNA. Evaluation on in vitro data of twenty mouse transcription factors shows that our method outperforms a method based on simple-instance learning with DNA structural properties, and the widely used k-mer counting method, for nineteen out of twenty of the transcription factors. Our analysis showed that the MIL3D approach can utilize subtle structural similarities when a strong sequence consensus is not available. Combining multiple-instance learning and structural properties of DNA has promising potential for studying biological regulatory networks.

  5. Gaussian Multiple Instance Learning Approach for Mapping the Slums of the World Using Very High Resolution Imagery

    Vatsavai, Raju [ORNL

    2013-01-01

    In this paper, we present a computationally efficient algo- rithm based on multiple instance learning for mapping infor- mal settlements (slums) using very high-resolution remote sensing imagery. From remote sensing perspective, infor- mal settlements share unique spatial characteristics that dis- tinguish them from other urban structures like industrial, commercial, and formal residential settlements. However, regular pattern recognition and machine learning methods, which are predominantly single-instance or per-pixel classi- fiers, often fail to accurately map the informal settlements as they do not capture the complex spatial patterns. To overcome these limitations we employed a multiple instance based machine learning approach, where groups of contigu- ous pixels (image patches) are modeled as generated by a Gaussian distribution. We have conducted several experi- ments on very high-resolution satellite imagery, represent- ing four unique geographic regions across the world. Our method showed consistent improvement in accurately iden- tifying informal settlements.

    Introduction. An attractive facial appearance is considered nowadays to be a decisive factor in establishing successful interactions between humans. In relation to this topic, scientific literature states that some of the facial features have more impact then others, and important authors revealed that certain proportions between different anthropometrical landmarks are mandatory for an attractive facial appearance. Aim. Our study aims to assess if certain facial features count differently in people’s opinion while assessing facial attractiveness in correlation with factors such as age, gender, specific training and culture. Material and methods. A 5-item multiple choice illustrated questionnaire was presented to 236 dental students. The Photoshop CS3 software was used in order to obtain the sets of images for the illustrated questions. The original image was handpicked from the internet by a panel of young dentists from a series of 15 pictures of people considered to have attractive faces. For each of the questions, the images presented were simulating deviations from the ideally symmetric and proportionate face. The sets of images consisted in multiple variations of deviations mixed with the original photo. Junior and sophomore year students from our dental medical school, having different nationalities were required to participate in our questionnaire. Simple descriptive statistics were used to interpret the data. Results. Assessing the results obtained from the questionnaire it was observed that a majority of students considered as unattractive the overdevelopment of the lower third, while the initial image with perfect symmetry and proportion was considered as the most attractive by only 38.9% of the subjects. Likewise, regarding the symmetry 36.86% considered unattractive the canting of the inter-commissural line. The interviewed subjects considered that for a face to be attractive it needs to have harmonious proportions between the different facial

    William Cheselden was Great Britain's foremost surgeon/scientist in the first half of the 18th century. Cheselden directly challenged the Company of Barber-Surgeons' exclusive right to control dissection in London by being the first to conduct a regular series of anatomy lectures and demonstrations outside of the Company's Hall. He incorporated his lecture syllabus into a handbook of anatomy, The Anatomy of the Humane Body, which was used by students for nearly 100 years. Cheselden also wrote the text and drew the illustrations for a majestic atlas of comparative osteology, the Osteographia, or the Anatomy of the Bones. Cheselden used his superior knowledge of anatomy to reduce the morbidity and mortality associated with perineal lithotomy, one of the few operations possible in his era. Sagacious and pragmatic, Cheselden recognized that the enlightened practice of surgery beginning to take root in 18th-century London could flourish only under an autonomous body of surgeons. Cheselden used his personal funds and political skills to urge Parliament to pass legislation for the dissolution of the combined Company of Barber-Surgeons and the establishment of separate and distinct Surgeons' and Barbers' Companies. After disjoinder of the two groups on May 2, 1745, Cheselden served as one of the Wardens of the new Company of Surgeons--a predecessor of the Royal College of Surgeons of England. In 1746, Cheselden, who helped design the first Surgeons' Hall, served as the Company's Master.

    Modern phsyics experiments require tracking and modelling data and their associated uncertainties on a large scale, as well as the combined implementation of multiple independent data streams for sophisticated modelling and analysis. The Minerva Framework offers a centralized, user-friendly method of large-scale physics modelling and scientific inference. Currently used by teams at multiple large-scale fusion experiments including the Joint European Torus (JET) and Wendelstein 7-X (W7-X), the Minerva framework provides a forward-model friendly architecture for developing and implementing models for large-scale experiments. One aspect of the framework involves so-called data sources, which are nodes in the graphical model. These nodes are supplied with engineering and physics parameters. When end-user level code calls a node, it is checked network-wide against its dependent nodes for changes since its last implementation and returns version-specific data. Here, a filterscope data node is used as an illustrative example of the Minerva Framework's data management structure and its further application to Bayesian modelling of complex systems. This work has been carried out within the framework of the EUROfusion Consortium and has received funding from the Euratom research and training programme 2014-2018 under Grant Agreement No. 633053.

    2010-07-01

    This book explains how radiology can be a powerful tool for establishing the diagnosis of many internal medicine diseases that are usually diagnosed on the basis of their laboratory or clinical presentation. It is organized in the classic fashion for internal medicine books, with eleven chapters covering the different internal medicine specialties. Within these chapters, more than 450 diseases are considered, some of which are rarely encountered but are nonetheless significant. For each disease, radiological and clinical features are displayed in images and high-quality digital medical illustrations, and those differential diagnoses are identified that can be ruled out by imaging alone. In addition, the pathophysiology underlying the radiological features is described, enabling the reader to understand why a particular sign is seen on MR images, CT scans, or plain radiographs. The book will serve as an excellent radiological atlas for internal medicine practitioners and family physicians, showing disease presentations that may be hard to find in standard medical textbooks and explaining which imaging modalities are likely to be most informative in particular patients.

    2017-09-01

    Imbalanced classification is related to those problems that have an uneven distribution among classes. In addition to the former, when instances are located into the overlapped areas, the correct modeling of the problem becomes harder. Current solutions for both issues are often focused on the binary case study, as multi-class datasets require an additional effort to be addressed. In this research, we overcome these problems by carrying out a combination between feature and instance selections. Feature selection will allow simplifying the overlapping areas easing the generation of rules to distinguish among the classes. Selection of instances from all classes will address the imbalance itself by finding the most appropriate class distribution for the learning task, as well as possibly removing noise and difficult borderline examples. For the sake of obtaining an optimal joint set of features and instances, we embedded the searching for both parameters in a Multi-Objective Evolutionary Algorithm, using the C4.5 decision tree as baseline classifier in this wrapper approach. The multi-objective scheme allows taking a double advantage: the search space becomes broader, and we may provide a set of different solutions in order to build an ensemble of classifiers. This proposal has been contrasted versus several state-of-the-art solutions on imbalanced classification showing excellent results in both binary and multi-class problems.

    2017-02-01

    Asking teachers what the term 'teaching' means to them can be a useful first activity in a faculty development session, as it typically leads to an engaging and enlightening discussion for participants and facilitators. Mapping their responses to 'conceptions of teaching' (sets of assumptions, knowledge and beliefs about teaching) in the literature seems particularly helpful in illuminating the inconsistencies, gaps and additional ways of thinking about teaching that participants may wish to consider. At least 25 conceptions of teaching can be identified in the literature. Each of these are briefly described and illustrated in this article, along with detailed examples and suggestions of how conceptions of teaching can be explored in faculty development. There is evidence that a teacher's conceptions of teaching affect the way that they approach their teaching, which in turn can affect learner learning. There is also some evidence that helping teachers examine and develop their conceptions of teaching may be more effective and have more impact on learner learning than other forms of faculty development. Different conceptions of teaching seem to be more or less appropriate in different teaching situations and contexts. It is likely that the more ways in which teachers can conceptualise and reflect on what they are doing, and why, the more adaptable, responsive and effective their teaching will be. Teachers have much to gain from learning more about themselves, their values and assumptions, and how these can influence their practice. This article offers a practical approach aimed at helping them to achieve this. A teacher's conceptions of teaching affect the way that they approach their teaching. © 2017 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

  14. An illustrated landslide handbook for developing nations

    2008-01-01

    As landslides continue to be a hazard that account for large numbers of human and animal casualties, property loss, and infrastructure damage, as well as impacts on the natural environment, it is incumbent on developed nations that resources be allocated to educate affected populations in less developed nations, and provide them with tools to effectively manage this hazard. Given that the engineering, planning and zoning, and mitigation techniques for landslide hazard reduction are more accessible to developed nations, it is crucial that such landslide hazard management tools be communicated to less developed nations in a language that is not overly technical, and provides information on basic scientific explanations on where, why and how landslides occur. The experiences of the United States, Canada, and many other nations demonstrate that, landslide science education, and techniques for reducing damaging landslide impacts may be presented in a manner that can be understood by the layperson. There are various methods through which this may be accomplished–community-level education, technology transfer, and active one-on-one outreach to national and local governments, and non-governmental organizations (NGOs), who disseminate information throughout the general population. The population at large can also benefit from the dissemination of landslide information directly to individual community members. The United States Geological Survey and the Geological Survey of Canada have just published and will distribute a universal landslide handbook that can be easily made available to emergency managers, local governments, and individuals. The handbook, “The Landslide Handbook: A Guide to Understanding Landslides” is initially published as U.S. Geological Survey Circular 1325, in English, available in print, and accessible on the internet. It is liberally illustrated with schematics and photographs, and provides the means for a basic understanding of landslides, with

    Full Text Available Ant colony optimization (ACO performs very well on many hard optimization problems, even though no good worst case guarantee can be given. Understanding the effects of different ACO parameters and the structural features of the considered problem on algorithm performance has become an interesting problem. In this paper, we study structural features of easy and hard instances of the Traveling Salesperson problem for a well-known ACO variant called Max Min Ant System MMAS for several parameter settings. The four considered parameters are the importance of pheromone values, the heuristic information, the pheromone update strength and the number of ants. We further use this knowledge to predict the best parameter setting for a wide range of instances taken from TSPLIB.

    Full Text Available We address a logistics districting problem faced by a parcel company whose operations consist of picking up and delivering packages over a service region. The districting process aims to find a partition of the service region into delivery and collection zones that may be served by a single vehicle that departs from a central depot. Criteria to be optimized are to balance workload content among the districts and to create districts of compact shape. A solution approach based on a hybrid procedure that combines elements of GRASP and Tabu Search (TS is proposed to solve large-scale instances. Numerical experimentation is performed considering different instance sizes and types. Results show that the proposed solution approach is able to solve large-scale instances in reasonable computational times with good quality of the solutions obtained. To determine the quality of the solutions, results are compared with CPLEX solutions and with the current real solution to highlight the benefits of the proposed approach. Conclusions and recommendations for further research are provided.

    2016-12-01

    Full Text Available The Parisian Revue Illustrée (1885–1912, a middle-class periodical of broad circulation and sophisticated iconography, lets us examine the expansion of fin-de-siècle culture beyond the so-called ‘petites revues’, particularly in the years 1894–1903. Through this fashionable all-publics fortnightly, typically fin-de-siècle tales and songs on transient motives, replete with Art Nouveau images and ornamentation, reach bourgeois households. The article shows the niche category the magazine occupied through its copious and exciting iconography. Using unpublished correspondence and print material culture, it throws light on the ways its editors turned the more refined parts of the magazine into deluxe photo-mechanically produced books. The study focuses on two men, René Baschet, the Revue’s editor from 1889 to 1904, and Jérôme Doucet, his assistant editor from July 1897 to 1902, and two fin-de-siècle writers, Catulle Mendès and Jean Lorrain, as well as up-coming artists André Cahard, Henry Bellery-Desfontaines, Manuel Orazi, and Carloz Schwabe. The case shows that sophisticated illustration was a financial spur that came cheap while it supported the so-called ‘decadent’ writings. Further, with refined taste, numerous connexions to artists, and work for a Dutch publisher, Jérôme Doucet emerges as a key figure behind the scenes.

    2017-08-01

    Spectral approaches of network analysis heavily rely upon the eigendecomposition of the graph Laplacian. For instance, in graph signal processing, the Laplacian eigendecomposition is used to define the graph Fourier trans- form and then transpose signal processing operations to graphs by implementing them in the spectral domain. Here, we build on recent work that generalized Slepian functions to the graph setting. In particular, graph Slepi- ans are band-limited graph signals with maximal energy concentration in a given subgraph. We show how this approach can be used to guide network analysis; i.e., we propose a visualization that reveals network organization of a subgraph, but while striking a balance with global network structure. These developments are illustrated for the structural connectome of the C. Elegans.

    Automated assignment of protein function has received considerable attention in recent years for genome-wide study. With the rapid accumulation of genome sequencing data produced by high-throughput experimental techniques, the process of manually predicting functional properties of proteins has become increasingly cumbersome. Such large genomics data sets can only be annotated computationally. However, automated assignment of functions to unknown protein is challenging due to its inherent difficulty and complexity. Previous studies have revealed that solving problems involving complicated objects with multiple semantic meanings using the multi-instance multi-label (MIML) framework is effective. For the protein function prediction problems, each protein object in nature may associate with distinct structural units (instances) and multiple functional properties (class labels) where each unit is described by an instance and each functional property is considered as a class label. Thus, it is convenient and natural to tackle the protein function prediction problem by using the MIML framework. In this paper, we propose a sparse Markov chain-based semi-supervised MIML method, called Sparse-Markov. A sparse transductive probability graph is constructed to encode the affinity information of the data based on ensemble of Hausdorff distance metrics. Our goal is to exploit the affinity between protein objects in the sparse transductive probability graph to seek a sparse steady state probability of the Markov chain model to do protein function prediction, such that two proteins are given similar functional labels if they are close to each other in terms of an ensemble Hausdorff distance in the graph. Experimental results on seven real-world organism data sets covering three biological domains show that our proposed Sparse-Markov method is able to achieve better performance than four state-of-the-art MIML learning algorithms.

  5. Theory, For Instance

    DEFF Research Database (Denmark)

    Balle, Søren Hattesen

    “). In the philosophical tradition this is also how the style of theory has been figured, that is to say: as something that is incidental to it or just happens to be around as so much paraphernalia. In my reading of Stevens’ poem I shall argue that this is exactly the position from which Stevens takes off when he assumes...... the task of writing a personified portrait of theory. Theory emerges as always beside(s) itself in what constitutes its style, but the poem also suggests that theory’s style is what gives theory both its power and its contingency. Figured as a duchess Theoria is only capable of retaining her power...... and detachment from Praxis through the practice of a certain style. Otherwise, she remains powerless and isolated as a mere title without substance. Just as a duchess needs her “carriage“, her “vestibule” and her “high bed sheltered by curtains” in order to place her in a position from which to rule her duchy...

  6. Roles of Illustrators in Visual Communication of Scientific Knowledge

    Full Text Available Scientific knowledge is the knowledge accumulated by systematic studies and organized by general principles. Visual, verbal, numeric, and other types of representation are used to communicate scientific knowledge. Scientific illustration is the visual representation of objects and concepts in order to record and to convey scientific knowledge(Ford, 1993. There are some discussions on scientific illustrations in history, philosophy and the sociology of science(Burri & Dumit, 2008, but little has been done on the creation of scientific illustrations by illustrators. This study focuses on the creation of scientific illustrations by illustrators. The purpose is to show how illustrators create the visual messages in communications of scientific knowledge. Through analysis of semi-structured interviews with 6 professional illustrators, creators and art directors, it is showed that illustrators select and edit scientific information, add non-scientific information, and organize information into one visual representation of scientific knowledge. The implication of this research will provide a new perspective to multisensory communication of scientific knowledge.

    The purpose of this study was to determine whether audiovisual information, describing the process of undergoing and recovering from anesthesia, could reduce anxiety levels in parents before their child's induction of anesthesia. One hundred and eleven parents were recruited into this study. Of these 56 were randomized to a control group and 55 to an intervention group. All parents completed the Amsterdam Preoperative Anxiety and Information Scale (APAIS) questionnaires on admission to hospital on the day of surgery and then again just before accompanying their child to the anesthetic room. In addition to the normal preoperative preparation, parents randomized into the study group watched a short 8-min information video after completing the first questionnaire. The video illustrated the events and procedures surrounding a child's admission to hospital for day-case surgery, including the induction of anesthesia. The results were analyzed using repeated measures of anova. There was a statistically significant reduction in anxiety and desire for information in the intervention group compared with the control group (P anxiety in the intervention group indicates that preoperative information videos are an effective method of reducing anxiety in parents. Furthermore, the reduction in need for information score in the intervention group indicates that preoperative videos may be a useful tool for providing parents with information.

  8. Automatic detection and recognition of multiple macular lesions in retinal optical coherence tomography images with multi-instance multilabel learning

    Detection and recognition of macular lesions in optical coherence tomography (OCT) are very important for retinal diseases diagnosis and treatment. As one kind of retinal disease (e.g., diabetic retinopathy) may contain multiple lesions (e.g., edema, exudates, and microaneurysms) and eye patients may suffer from multiple retinal diseases, multiple lesions often coexist within one retinal image. Therefore, one single-lesion-based detector may not support the diagnosis of clinical eye diseases. To address this issue, we propose a multi-instance multilabel-based lesions recognition (MIML-LR) method for the simultaneous detection and recognition of multiple lesions. The proposed MIML-LR method consists of the following steps: (1) segment the regions of interest (ROIs) for different lesions, (2) compute descriptive instances (features) for each lesion region, (3) construct multilabel detectors, and (4) recognize each ROI with the detectors. The proposed MIML-LR method was tested on 823 clinically labeled OCT images with normal macular and macular with three common lesions: epiretinal membrane, edema, and drusen. For each input OCT image, our MIML-LR method can automatically identify the number of lesions and assign the class labels, achieving the average accuracy of 88.72% for the cases with multiple lesions, which better assists macular disease diagnosis and treatment.

    Many scientific inventions (SI) throughout history were inspired by heuristic prototypes (HPs). For instance, an event or piece of knowledge similar to displaced water from a tub inspired Archimedes' principle. However, the neural mechanisms underlying this insightful problem solving are not very clear. Thus, the present study explored the neural correlates used to solve SI problems facilitated by HPs. Each HP had two versions: a literal description with an illustration (LDI) and a literal description with no illustration (LDNI). Thirty-two participants were divided randomly into these two groups. Blood oxygenation level-dependent fMRI contrasts between LDI and LDNI groups were measured. Greater activity in the right middle occipital gyrus (RMOG, BA19), right precentral gyrus (RPCG, BA4), and left middle frontal gyrus (LMFG, BA46) were found within the LDI group as compared to the LDNI group. We discuss these results in terms cognitive functions within these regions related to problem solving and memory retrieval. Copyright © 2015 Elsevier Inc. All rights reserved.

  18. Illustration-inspired depth enhanced volumetric medical visualization.

    Svakhine, Nikolai A; Ebert, David S; Andrews, William M

    2009-01-01

    Volume illustration can be used to provide insight into source data from CT/MRI scanners in much the same way as medical illustration depicts the important details of anatomical structures. As such, proven techniques used in medical illustration should be transferable to volume illustration, providing scientists with new tools to visualize their data. In recent years, a number of techniques have been developed to enhance the rendering pipeline and create illustrative effects similar to the ones found in medical textbooks and surgery manuals. Such effects usually highlight important features of the subject while subjugating its context and providing depth cues for correct perception. Inspired by traditional visual and line-drawing techniques found in medical illustration, we have developed a collection of fast algorithms for more effective emphasis/de-emphasis of data as well as conveyance of spatial relationships. Our techniques utilize effective outlining techniques and selective depth enhancement to provide perceptual cues of object importance as well as spatial relationships in volumetric datasets. Moreover, we have used illustration principles to effectively combine and adapt basic techniques so that they work together to provide consistent visual information and a uniform style.

    2013-06-01

    This study investigated the preferences of medical professionals and laypersons with respect to the level of detail shown in medical illustrations (i.e. graphic art shown in patient education materials) and the complexity of the subject being depicted (i.e. a visually simple versus a visually complex subject). Additionally, respondent's age, gender, and art background were recorded to yield further insight. The results showed that generally there was preference for high-detail (complex) illustrations between the two groups, though the professionals group was somewhat more diverse in their choices. The other variables had no impact on illustration preference.

  9. An on-line learning tracking of non-rigid target combining multiple-instance boosting and level set

    Chen, Mingming; Cai, Jingju

    2013-10-01

    Visual tracking algorithms based on online boosting generally use a rectangular bounding box to represent the position of the target, while actually the shape of the target is always irregular. This will cause the classifier to learn the features of the non-target parts in the rectangle region, thereby the performance of the classifier is reduced, and drift would happen. To avoid the limitations of the bounding-box, we propose a novel tracking-by-detection algorithm involving the level set segmentation, which ensures the classifier only learn the features of the real target area in the tracking box. Because the shape of the target only changes a little between two adjacent frames and the current level set algorithm can avoid the re-initialization of the signed distance function, it only takes a few iterations to converge to the position of the target contour in the next frame. We also make some improvement on the level set energy function so that the zero level set would have less possible to converge to the false contour. In addition, we use gradient boost to improve the original multi-instance learning (MIL) algorithm like the WMILtracker, which greatly speed up the tracker. Our algorithm outperforms the original MILtracker both on speed and precision. Compared with the WMILtracker, our algorithm runs at a almost same speed, but we can avoid the drift caused by background learning, so the precision is better.

    Full Text Available We report the discovery and present a detailed analysis of a freshwater bivalve from Shuidonggou Locality 2, layer CL3. This layer is located c. 40 cm below layer CL2, which has yielded numerous ostrich eggshell beads. The shell is identified as the valve of a Corbicula fluminea. Data on the occurrence of this species in the Shuidonggou region during Marine Isotope Stage 3 and taphonomic analysis, conducted in the framework of this study, of a modern biocoenosis and thanatocoenosis suggest that the archeological specimen was collected at one of the numerous fossil or sub-fossil outcrops where valves of this species were available at the time of occupation of level CL3. Experimental grinding and microscopic analysis of modern shells of the same species indicate that the Shuidonggou shell was most probably ground on coarse sandstone to open a hole on its umbo, attach a thread, and use the valve as a personal ornament. Experimental engraving of freshwater shells and microscopic analysis identify an incision crossing the archaeological valve outer surface as possible deliberate engraving. Reappraisal of the site chronology in the light of available radiocarbon evidence suggests an age of at least 34-33 cal kyr BP for layer CL3. Such estimate makes the C. fluminea recovered from CL3 one of the earliest instances of personal ornamentation and the earliest example of a shell bead from China.

    Full Text Available Abstract Background Teaching of motor skills is fundamental to physical therapy practice. In order to optimize the benefits of these teaching and training efforts, various forms of patient education material are developed and handed out to patients. One very important fact has been overlooked. While comparative effectiveness of various modes of instruction has been studied in adults, attention has not been paid to the fact that learning capabilities of children are different from that of adults. The intent of the present study is to compare the effectiveness of video and handout mode of instructions specifically on children. Methods A total of 115 normal elementary-age children aged 10 to 12 years of age were studied. The children were randomized into two groups: A the video group, and B the handout group. The video group viewed the video for physical therapy exercises while the handout group was provided with paper handouts especially designed according to the readability of their age group. Results Statistical analysis using the student's't' test showed that subjects of both the video and handout groups exhibited equal overall performance accuracy. There was no significant difference between the groups both in acquisition and retention accuracy tests. Conclusion The findings of the present study suggest that if the readability and instructional principles applicable to different target age groups are strictly adhered to, then both video as well as handout modes of instructions result in similar feedback and memory recall in ten to twelve year-old children. Principles of readability related to the patient age are of utmost importance when designing the patient education material. These findings suggest that the less expensive handouts can be an effective instructional aid for teaching exercises to children with various neuromuscular, rheumatic, and orthopedics conditions and the most costly videotape techniques are not necessarily better.

    The literature shows that the quality of communication is usually determined from a professional perspective. Patients or lay people are seldom involved in the development of quality indicators or communication. To give voice to the lay people perspective on what constitutes 'good communication' by evoking their reactions to variations in physician communication. Lay people from four different countries watched the same videotaped standardized medical encounters and discussed their preferences in gender-specific focus groups who were balanced in age groups. Two hundred and fifty-nine lay people (64 NL, 72 IT, 75 UK and 48 BE) distributed over 35 focus groups of 6-8 persons each. Comments on doctors' behaviours were classified by the GULiVer framework in terms of contents and preferences. Participants prevalently discussed 'task-oriented expressions' (39%: competency, self-confident, providing solutions), 'affective oriented/emotional expressions' (25%: empathy, listening, reassuring) and 'process-oriented expressions' (23%: flexibility, summarizing, verifying). 'Showing an affective attitude' was most appreciated (positive percentage within category: 93%, particularly facilitations and inviting attitude), followed by 'providing solution' (85%). Among disfavoured behaviour, repetitions (88%), 'writing and reading' (54%) and asking permission (42%) were found. Although an affective attitude is appreciated by nearly everybody, people may vary widely in their communication needs and preferences: what is 'good communication' for one person may be disliked or even a source of irritation for another. A physician should be flexible and capable of adapting the consultation to the different needs of different patients. This challenges the idea of general communication guidelines. © 2013 John Wiley & Sons Ltd.

    To determine to what degree assessment of mobility based on comparison of videotape recordings before and after courses of physiotherapy in patients with chronic multiple sclerosis (MS) is reliable, correlates with 'live' assessments and indicates benefit. Prospective data collection within a randomized crossover controlled trial of physiotherapy at home, as an outpatient, or 'no therapy' in 40 patients. Hospital outpatients: outpatient and home physiotherapy. Mobility change based on a comparison of short video recordings before and after each treatment period was scored independently by two physiotherapists blinded to therapy type and other measures of outcome. Scores were compared with changes in the Rivermead Mobility Index (RMI) and other indices assessed by a physiotherapist in the patient's home. The two video observers agreed substantially on patient outcome. Changes in walking based on video correlated with RMI for home treatment (r = 0.41, p = 0.008) but not for hospital or no treatment periods (r = 0.14 and 0.15): video changes correlated with the 'live' assessor's global change score inconsistently ('no therapy' r = 0.48, p = 0.002, hospital r = 0.30, p = 0.06 and home r = 0.17, p = 0.30 treatment periods). Based on video data alone, improved mobility was evident following home therapy for only one observer but not for the other or the averaged scores of both. There was substantial agreement between two observers deciding on change in mobility based on independent blinded evaluation of short video sequences. However the correlations of these with 'live' assessments were variable. Physiotherapy had a less clear benefit on mobility based on video analysis alone compared with 'live' assessments. The study highlights the need for more objective measures of habitual mobility over longer periods.

  19. The history and illustration of anatomy in the Middle Ages.

    2013-11-01

    This article reviews the influence of key figures on the pictorial representation of anatomy and the evolution of anatomical illustration during the Middle Ages until the time of the Renaissance, based on medical history books, journals and ancient medical books. During the early period in the Middle Ages, most illustrations were traditional drawings of emblematic nature, oftentimes unrealistic, not only because the precise knowledge of anatomy was lacking but also because the objective was to elucidate certain principles for teaching purposes. Five figure-series that came down to us through ancient manuscripts and textbooks represent the best examples of such traditional illustrations. With the advent of human dissection in the 13th and 14th centuries, a significant transformation in the depiction of anatomy began to project the practice of human dissection, as we see in the works of Mondino de Luzzi, Henri de Mondeville and Guido de Vigevano. After the invention of book printing in the second half of the 15th century, the reproduction of books was commonly practised and the woodcut made multiplication of pictures easier. Peter of Abano, Hieronymous Brunschwig, Johannes de Ketham, Johannes Peyligk, Gregory Reisch, Magnus Hundt, Laurentius Phryesen and many more included several anatomical illustrations in their treatises that demonstrated the development of anatomical illustration during the later Middle Ages.

The research showed that: the first manuscript with colored pictures include 2 volumes, titled Animaux et Plantes de Chine collected in Library of Museum National d'Historie Naturelle (MNHN);the other manuscript with colored pictures has only 1 volume, titled Botanique Chinoise collected in Library of Societe Asiatique, College de France, which were identified as illustrations of Ben cao gang mu (Compendium of Materia Medica) (1640 edition) by Li Shi-zhen. These pictures were copied by P. d'Incarville, and are similar to Plantes fleurs et arbres de Chine in Bibliotheque de l'Institut de Franceand, Collection de Plantes Veneneuses de la Chine Gravees et Imprimees en Couleurs par les Missionnaries Jesuites in Bibliotheque Nationale de France, respectively. The latter two manuscripts were identified as illustrations of Ben cao pin hui jing yao (Essential Collections of Materia Medica) (1700 edition).

  1. Learning hatching for pen-and-ink illustration of surfaces

    KAUST Repository

    Kalogerakis, Evangelos

    2012-01-01

    This article presents an algorithm for learning hatching styles from line drawings. An artist draws a single hatching illustration of a 3D object. Her strokes are analyzed to extract the following per-pixel properties: hatching level (hatching, cross-hatching, or no strokes), stroke orientation, spacing, intensity, length, and thickness. A mapping is learned from input geometric, contextual, and shading features of the 3D object to these hatching properties, using classification, regression, and clustering techniques. Then, a new illustration can be generated in the artist\\'s style, as follows. First, given a new view of a 3D object, the learned mapping is applied to synthesize target stroke properties for each pixel. A new illustration is then generated by synthesizing hatching strokes according to the target properties. © 2012 ACM.

    Full Text Available This article explores the two series of visits to the artist's studio that appeared in the famed French illustrated magazine L'Illustration in the 1850s and in 1886. An in-depth examination of both the texts and images reveals the verbal and visual tropes used to characterize the artists and their spaces, linking these to broader notions of "the artist" – his moral characteristics, behaviors, and artistic practice – as well as to the politics of the art world and the (bourgeois ideology of L'Illustration. The aim is to uncover not only the language but also the mechanics of the "mediatization" of the image of the artist in this crucial period.

    Directory of Open Access Journals (Sweden)

    Sînziana Șerbănescu

    2016-12-01

    Full Text Available A rather cross time aspect that is to be addressed by this research is the appropriation of the illustration by classic arts or by what is called new media, as they are defined by the work Remediation (Bolter & Grusin, 2000. Starting from new media and how they are created and function nowadays, analyzing the fascination induced by the new technologies, Bolter and Grusin initiate a theory of remediation which is meant to challenge the so called novelty of the creations of the contemporary digital culture. By discussing the remediation as one of the most important characteristics of new media, Bolter and Grusin prove that this is a sine qua non condition of every work of art. Starting from this theory, we are interested in analyzing the equation encompassing illustrations, myths and their relation with the reality layers that they remediate. We will try to answer the question: how does myths and illustration build layers towards the public and what are the forms they embrace today? We will base our research on a corpus of images (illustrations where mythical representations are present.

    2009-01-01

    The devastating power of hurricanes was evident during the 2005 hurricane season, the most active season on record. This has prompted increased efforts by researchers to understand the physical processes that underlie the genesis, intensification, and tracks of hurricanes. This research aims at facilitating an improved understanding into the structure of hurricanes with the aid of visualization techniques. Our approach was developed by a mixed team of visualization and domain experts. To better understand these systems, and to explore their representation in NWP models, we use a variety of illustration-inspired techniques to visualize their structure and time evolution. Illustration-inspired techniques aid in the identification of the amount of vertical wind shear in a hurricane, which can help meteorologists predict dissipation. Illustration-style visualization, in combination with standard visualization techniques, helped explore the vortex rollup phenomena and the mesovortices contained within. We evaluated the effectiveness of our visualization with the help of six hurricane experts. The expert evaluation showed that the illustration-inspired techniques were preferred over existing tools. Visualization of the evolution of structural features is a prelude to a deeper visual analysis of the underlying dynamics.

  15. Does burnout among doctors affect their involvement in patients' mental health problems? A study of videotaped consultations

    Directory of Open Access Journals (Sweden)

    de Bakker Dinny H

    2009-08-01

    Full Text Available Abstract Background General practitioners' (GPs' feelings of burnout or dissatisfaction may affect their patient care negatively, but it is unknown if these negative feelings also affect their mental health care. GPs' available time, together with specific communication tools, are important conditions for providing mental health care. We investigated if GPs who feel burnt out or dissatisfied with the time available for their patients, are less inclined to encourage their patients to disclose their distress, and have shorter consultations, in order to gain time and energy. This may result in less psychological evaluations of patients' complaints. Methods We used 1890 videotaped consultations from a nationally representative sample of 126 Dutch GPs to analyse GPs' communication and the duration of their consultations. Burnout was subdivided into emotional exhaustion, depersonalisation and reduced accomplishment. Multilevel regression analyses were used to investigate which subgroups of GPs differed significantly. Results GPs with feelings of exhaustion or dissatisfaction with the available time have longer consultations compared to GPs without these feelings. Exhausted GPs, and GPs with feelings of depersonalisation, talk more about psychological or social topics in their consultations. GPs with feelings of reduced accomplishment are an exception: they communicate less affectively, are less patient-centred and have less eye contact with their patients compared to GPs without reduced accomplishment. We found no relationship between GPs' feelings of burnout or dissatisfaction with the available time and their psychological evaluations of patients' problems. Conclusion GPs' feelings of burnout or dissatisfaction with the time available for their patients do not obstruct their diagnosis and awareness of patients' psychological problems. On the contrary, GPs with high levels of exhaustion or depersonalisation, and GPs who are dissatisfied with the

    Rapid evolution in technology in the recent years has lead to availability of multiple options for cardiac imaging. Availability of multiple options of varying capability, poses a challenge for optimal imaging choice. While new imaging choices are added, some of the established methods find their role re-defined. State of the art imaging practices are limited to few specialist cardiac centres, depriving many radiologists and radiologist in-training of optimal exposure to the field. This presentation is aimed at providing a broad idea about complexity of clinical problem, imaging options and a large library of images of congenital heart disease. Some emphasis is made as to the need of proper balance between performing examination with technical excellence in an ideal situation against the need of the majority of patients who are investigated with less optimal resources. Cases of congenital cardiac disease are presented in an illustrative way, showing imaging appearances in multiple modalities, highlighting specific observations in given instance.

  17. MHC2MIL: a novel multiple instance learning based method for MHC-II peptide binding prediction by considering peptide flanking region and residue positions.

    Xu, Yichang; Luo, Cheng; Qian, Mingjie; Huang, Xiaodi; Zhu, Shanfeng

    2014-01-01

    Computational prediction of major histocompatibility complex class II (MHC-II) binding peptides can assist researchers in understanding the mechanism of immune systems and developing peptide based vaccines. Although many computational methods have been proposed, the performance of these methods are far from satisfactory. The difficulty of MHC-II peptide binding prediction comes mainly from the large length variation of binding peptides. We develop a novel multiple instance learning based method called MHC2MIL, in order to predict MHC-II binding peptides. We deem each peptide in MHC2MIL as a bag, and some substrings of the peptide as the instances in the bag. Unlike previous multiple instance learning based methods that consider only instances of fixed length 9 (9 amino acids), MHC2MIL is able to deal with instances of both lengths of 9 and 11 (11 amino acids), simultaneously. As such, MHC2MIL incorporates important information in the peptide flanking region. For measuring the distances between different instances, furthermore, MHC2MIL explicitly highlights the amino acids in some important positions. Experimental results on a benchmark dataset have shown that, the performance of MHC2MIL is significantly improved by considering the instances of both 9 and 11 amino acids, as well as by emphasizing amino acids at key positions in the instance. The results are consistent with those reported in the literature on MHC-II peptide binding. In addition to five important positions (1, 4, 6, 7 and 9) for HLA(human leukocyte antigen, the name of MHC in Humans) DR peptide binding, we also find that position 2 may play some roles in the binding process. By using 5-fold cross validation on the benchmark dataset, MHC2MIL outperforms two state-of-the-art methods of MHC2SK and NN-align with being statistically significant, on 12 HLA DP and DQ molecules. In addition, it achieves comparable performance with MHC2SK and NN-align on 14 HLA DR molecules. MHC2MIL is freely available at http

    We offer a perspective on the performance of current OCR systems by illustrating and explaining actual OCR errors made by three commercial devices. After discussing briefly the character recognition abilities of humans and computers, we present illustrated examples of recognition errors. The top level of our taxonomy of the causes of errors consists of Imaging Defects, Similar Symbols, Punctuation, and Typography. The analysis of a series of 'snippets' from this perspective provides insight into the strengths and weaknesses of current systems, and perhaps a road map to future progress. The examples were drawn from the large-scale tests conducted by the authors at the Information Science Research Institute of the University of Nevada, Las Vegas. By way of conclusion, we point to possible approaches for improving the accuracy of today's systems. The talk is based on our eponymous monograph, recently published in The Kluwer International Series in Engineering and Computer Science, Kluwer Academic Publishers, 1999.

  1. Forward-oriented design for learning: illustrating the approach

    Directory of Open Access Journals (Sweden)

    Yannis Dimitriadis

    2013-08-01

    Full Text Available This paper concerns sustainable approaches to design for learning, emphasising the need for designs to be able to thrive outside of the protective niches of project-based innovation. It builds on the “in medias res” framework and more specifically on a forward-oriented approach to design for learning: one that takes a pro-active design stance with respect to each of the phases of an extended lifecycle. We draw on fieldwork notes and interview data to describe two cases that illustrate some of the key features of the approach. Recommendations for further R&D in the area of design for learning are provided, derived from the theoretical framework, and illustrated in this paper.

    Four case histories out of 75 significant trampoline injuries (from a total of 198 injuries re-examined) plus two recent accidents (1979) are presented, illustrating that the trampoline is posing an undue risk of serious injury. It is argued that the only single factor capable of preventing trampoline injuries is a trampoline ban. This is imperative in schools. Trampoline clubs are advised to reconsider the risk factors involved.

    Hawes, Nicholas E.

    2004-01-01

    Over the past year, I have worked for my mentor, Beth Cooper, on a large variety of projects. Beth is the Manager of the Acoustical Testing Laboratory, which tests the acoustical emissions of payloads destined for the International Space Station. She is also responsible for educating, and developing new methods of educating, people of all occupational and educational backgrounds in hearing conservation. Beth spends much of her time developing new materials and strategies with which to train people and teach other people to train people in hearing conservation and noise emissions control. I have been helping Beth develop and market these materials by way of graphic design and scientific illustration. Last summer, I spent much of my time creating educational illustrations that visually explained particular concepts in Beth's presentations. Sometimes these illustrations were small "comics" while, at other times, they were an instructional series of illustrations. Since then, Beth and her lab have been developing and updating some materials which will be distributed free to hearing conservation and noise control professionals and others in related fields. I have helped with these projects by designing their packaging. In each instance, it was my responsibility to develop an aesthetically appealing package that would also, through its imagery, describe or summarize the contents of the product. I did this for 3 CD's (Auditory Demonstrations 11, MACSUG, and JeopEARdy) and saw them through their actual production and distribution. In addition to working with Beth, I work with the Imaging Technology Center on various imaging projects. Some of my activities include photo retouching and manipulation for videos and print. This summer, I also had the opportunity to develop a screen saver that would show of some of the photography contained on the soon-to-be-released "Highlights of the GRC Image Archives, vol. 2". I was also able to utilize my medical training to help several of

    This paper describes methods for explanatory and illustrative visualizations used to communicate aspects of Einstein's theories of special and general relativity, their geometric structure, and of the related fields of cosmology and astrophysics. Our illustrations target a general audience of laypersons interested in relativity. We discuss visualization strategies, motivated by physics education and the didactics of mathematics, and describe what kind of visualization methods have proven to be useful for different types of media, such as still images in popular science magazines, film contributions to TV shows, oral presentations, or interactive museum installations. Our primary approach is to adopt an egocentric point of view: The recipients of a visualization participate in a visually enriched thought experiment that allows them to experience or explore a relativistic scenario. In addition, we often combine egocentric visualizations with more abstract illustrations based on an outside view in order to provide several presentations of the same phenomenon. Although our visualization tools often build upon existing methods and implementations, the underlying techniques have been improved by several novel technical contributions like image-based special relativistic rendering on GPUs, special relativistic 4D ray tracing for accelerating scene objects, an extension of general relativistic ray tracing to manifolds described by multiple charts, GPU-based interactive visualization of gravitational light deflection, as well as planetary terrain rendering. The usefulness and effectiveness of our visualizations are demonstrated by reporting on experiences with, and feedback from, recipients of visualizations and collaborators.

  10. I La Galigo Folklore Illustration on Textile Media

    Full Text Available This project was an effort in conserving the I La Galigo epic story while at the same time adding value to silk, the famous textile product from South Sulawesi and the origin of I La Galigo. As a work of literature, I La Galigo is categorized as an epic. It is known locally as Sureq Galigo in Bugis. It is divided in a number of episodes or tereng. The most well-known tereng is the one which describes the relationship between Sawerigading and a princess called I We Cudai. From that relationship I La Galigo, the central character of this epic is born. For this project six of the most well-known episodes were selected because of the amount of available supporting data, both theoretical and visual. The selected episodes were translated from their original narrative form into visual language or images. The illustration technique used in this project was STP (Space Time Plane. With this technique every object is drawn from varying viewpoints in one frame, both in space and time. Hand embroidery was added to the painted images. The silk painting can be used as an interior element with value added by the I La Galigo illustrations. Keywords: I La Galigo; epic; Sulawesi; illustration; silk painting; space time plane.

  11. Vladimir Nabokov, un exemple d’aliénation créatrice Vladimir Nabokov, an Instance of Creative Alienation

    Directory of Open Access Journals (Sweden)

    Marie Bouchet

    2009-06-01

    Full Text Available The terms “strange” and “stranger” derive from extraneus, a Latin word literally meaning “outside of”. This article proposes to examine the notions of distance and limit which shape the consciousness of a foreigner / outsider—Vladimir Nabokov. Nabokov lost his native land when he was 18, and was condemned to remain a stranger in a foreign land. In his fiction, many “estranged” characters are to be found, especially as main focalizers or first-person narrators. The present article thus demonstrates how the concept of frontier is crucial to interpreting such alien status: these characters are forever estranged, due to geographical borders, temporal distances or linguistic barriers. Nabokov, himself a trilingual writer, challenged the very idea of a foreign language. His English, which he claimed was merely “second rate”, is indeed quite different from the style of American classics, yet it has a unique poetic flavor. Maybe because he “did not think in any language, but in images”, his condition as a foreigner was not felt as alienating. Contrary to most of his characters, hybridization seems to have been a powerful element inspiring his artistic impulse, as illustrated in his extraordinary linguistic virtuosity and his constant playing on words. Similarly, the repeated inclusion of other semiotic codes (painting, photography, advertisements,… shows that by playing with limits and the interpenetration of familiar and strange(r elements, Nabokov found a creative alternative to the usually alienating condition of being a foreigner.

    Full Text Available The books telling the story of Montserrat used to contain illustrative engravings. Montserrat presents us with a special case, because this monastery holds an uninterrupted record of illustrated texts or of texts with engraved images from the miniatures of the Llibre Vermell and the first fruits of the printing press to the 19th century. Admittedly, in the 16th, 17th and 18th centuries the books exhibit the engravings on the cover or within the first sheets; it is only in the 19th century that illustrations appear inserted in the text so as to make the story more agreeable. The images intensify the value of texts, since illustrations can help us understand the written word and may suggest other readings of the corresponding passages, clearer and more precise. Illustrations in the books on the history of a monastery are but a part of a larger set of ideas, projects and self-service which the Church aims at the reader. Furthermore, the iconographic models of the Virgin Mary and the Mountain are of great interest for the history of engraving and of the Catalan and Spanish devotions.

    Los libros en que se contaba la historia de Montserrat contenían estampas que los ilustraban. Montserrat es un caso inusual, porque posee un registro ininterrumpido de textos ilustrados o acompañados con imágenes grabadas, desde el Llibre Vermell y los primeros momentos de la imprenta hasta el siglo XIX. Bien es cierto que en los libros de los siglos XVI, XVII y XVIII sólo se colocan los grabados en la portada o en las primeras hojas; Hasta el siglo XIX no encontramos un tipo de ilustración insertada en el interior del texto amenizando la historia. Las imágenes intensifican el valor de los textos, porque nos ayudan a comprenderlos y a la vez sugieren nuevas lecturas, más precisas y claras.

    2010-01-01

    Video-taping clinical sessions is a common practice among social workers so that the tapes may be used for clinical supervision and reviewed with the individuals or families involved. They are usually underused for research purposes. This article reports on an innovative research method using such tapes as a basis for clinical data mining to explore the bereavement experience of Chinese people in Hong Kong. Using this data, a rich item pool, containing both negative and positive reactions, was generated to allow the development of a culturally relevant measurement tool of grief reactions. The data also facilitated theory building in the area of grief and bereavement. This study extended the use of video-tapes in clinical sessions for research purposes and helped to collect reliable and timely data in a non-intrusive way. It has also advanced the use of quantitative data in the clinical data-mining approach. The study encouraged collaboration between clinicians and researchers to develop knowledge and skills about their special target group of clients.

  16. Illustration of Ares I and Ares V Launch Vehicles

    2006-01-01

    Named for the Greek god associated with Mars, the NASA developed Ares launch vehicles will return humans to the moon and later take them to Mars and other destinations. In this early illustration, the vehicle depicted on the left is the Ares I. Ares I is an inline, two-stage rocket configuration topped by the Orion crew vehicle and its launch abort system. In addition to its primary mission of carrying four to six member crews to Earth orbit, Ares I may also use its 25-ton payload capacity to deliver resources and supplies to the International Space Station (ISS), or to 'park' payloads in orbit for retrieval by other spacecraft bound for the moon or other destinations. The Ares I employs a single five-segment solid rocket booster, a derivative of the space shuttle solid rocket booster, for the first stage. A liquid oxygen/liquid hydrogen J-2X engine derived from the J-2 engine used on the second stage of the Apollo vehicle will power the Ares V second stage. The Ares I can lift more than 55,000 pounds to low Earth orbit. The vehicle illustrated on the right is the Ares V, a heavy lift launch vehicle that will use five RS-68 liquid oxygen/liquid hydrogen engines mounted below a larger version of the space shuttle external tank, and two five-segment solid propellant rocket boosters for the first stage. The upper stage will use the same J-2X engine as the Ares I. The Ares V can lift more than 286,000 pounds to low Earth orbit and stands approximately 360 feet tall. This versatile system will be used to carry cargo and the components into orbit needed to go to the moon and later to Mars. Both vehicles are subject to configuration changes before they are actually launched. This illustration reflects the latest configuration as of September 2006.

    2014-05-01

    We present our research results in the Geoillustrator project. The project has been going for four years and is ending in March. It was aimed at developing a rapid sketching tool for generating geological illustrations and animations for understanding the processes that have led to a current subsurface configuration. The sketching tool facilitates effective dissemination of ideas, e.g. through generation of interactive geo-scientific illustrations for interdisciplinary communication and communication to decision makers, media and lay persons. This can improve work processes in early phases of oil and gas exploration where critical decisions have to be taken based on limited information. It is a challenge for involved specialists in early exploration phases to externalize their ideas, and effectively achieve consensus in multidisciplinary working groups. In these work processes, a tool for rapid sketching of geology would be very useful for expressing geological hypotheses and creating and comparing different evolution scenarios. Often, decisions are influenced by factors that are not relevant, e.g. the geologists who produce the most polished illustrations of their hypothesis have a higher probability for getting their theories through to decision makers as it is more clearly communicated. This results in a competitive advantage for geologists who are skilled in creating illustrations. Having a tool that would lift the ability of all geologists to express their ideas to an equal level would result in more alternatives and better foundation for decision making. Digital sketching will also allow capturing otherwise lost material which can constitute a large amount of mental work and ideas. The results of sketching are currently scrapped as paper or erased from the blackboard or exist only as rough personal sketches. By using a digital sketching tool, the sketches can be exported to a form usable in modelling tools used in later phases of exploration. Currently, no

    The description of motion in a noninertial reference frame, and especially the Coriolis force, is a topic that often comes up even when it is not in the curriculum. Sometimes students may have seen a Foucault pendulum at a museum or they may have heard a discussion about the draining of bathtubs. At those times it would be nice to be able to give a simple and clear demonstration in the next lesson. At a more advanced level, the description of the Coriolis and the centrifugal force is a nice illustration of the use of vector algebra.

    Ultrasound has become a widely used diagnostic imaging modality in medicine because of its safety and portability. Because of rapid advances in technology, in recent years, sonographic imaging quality has significantly increased. Despite these advances, the potential to encounter artifacts while imaging remains.This article classifies both common and uncommon gray-scale and Doppler ultrasound artifacts into those resulting from physiology and those caused by hardware. A brief applied-physics explanation for each artifact is listed along with an illustrated diagram. The imaging appearance of artifacts is presented in case examples, along with strategies to minimize the artifacts in real time or use them for clinical advantage where applicable.

    Poor quality of care and access to effective and affordable interventions have been attributed to constraints and bottlenecks within and outside the health system. However, there is limited understanding of health system barriers to utilization and delivery of appropriate, high-impact, and cost-effective interventions at the point of service delivery in districts and sub-districts in low-income countries. In this study we illustrate the use of the bottleneck analysis approach, which could be used to identify bottlenecks in service delivery within the district health system. A modified Tanahashi model with six determinants for effective coverage was used to determine bottlenecks in service provision for maternal and newborn care. The following interventions provided during antenatal care were used as tracer interventions: use of iron and folic acid, intermittent presumptive treatment for malaria, HIV counseling and testing, and syphilis testing. Data from cross-sectional household and health facility surveys in Mayuge and Namayingo districts in Uganda were used in this study. Effective coverage and human resource gaps were identified as the biggest bottlenecks in both districts, with coverage ranging from 0% to 66% for effective coverage and from 46% to 58% for availability of health facility staff. Our findings revealed a similar pattern in bottlenecks in both districts for particular interventions although the districts are functionally independent. The modified Tanahashi model is an analysis tool that can be used to identify bottlenecks to effective coverage within the district health system, for instance, the effective coverage for maternal and newborn care interventions. However, the analysis is highly dependent on the availability of data to populate all six determinants and could benefit from further validation analysis for the causes of bottlenecks identified.

    Full Text Available Designing clothes has become easier with the use of clothing design software. One of the most popular and basic software made for garments design is Adobe Illustrator. It enables designers and small to medium businesses to create clothing designs with easy access to all assets, including images, colors, brushes, and type styles. While Illustrator has all the necessary elements and features that are ideal for creating designer clothing, GIMP provides basic set of tools for image editing. When used in combination with one another, these two programs provide just about all the tools an apparel designer needs to draw fashion design sketches, technical flat sketches, CAD presentations, graphic artworks, design embroideries etc. In this paper we show how to use the instruments of those two software in order to draw a woman jacket’s garments components and to fill with texture the jacket created. By utilizing Illustrator’s Symbol we created libraries of jacket components (puller zipper, label, then the brushes to design the zipper detail. Finally, by a drag and drop we added the zipper, the zipper puller and the label. GIMP gave us access to precise fabric textures which make our output so realistic that you can almost touch the fabric.

    The model of Bobath clinical practice provides a framework identifying the unique aspects of the Bobath concept in terms of contemporary neurological rehabilitation. The utilisation of a framework to illustrate the clinical application of the Bobath concept provides the basis for a common understanding with respect to Bobath clinical practice, education, and research. The development process culminating in the model of Bobath clinical practice is described. The use of the model in clinical practice is illustrated using two cases: a client with a chronic incomplete spinal cord injury and a client with a stroke. This article describes the clinical application of the Bobath concept in terms of the integration of posture and movement with respect to the quality of task performance, applying the Model of Bobath Clinical Practice. Facilitation, a key aspect of Bobath clinical practice, was utilised to positively affect motor control and perception in two clients with impairment-related movement problems due to neurological pathology and associated activity limitations and participation restrictions - the outcome measures used to reflect the individual clinical presentation.

Descriptors for mediation had not been developed in the 1993–6 Swiss National Research Project that produced the original set of illustrative descriptors for the CEFR. The work took place in the context of a wider 2013–6 project to provide an extended set of CEFR illustrative descriptors. The article describes the way in which the approach taken to mediation in the project is broader than the one taken in the presentation of mediation in the CEFR text in 2001. In addition to information transfer (conveying received information the new scheme also embraces the construction of meaning and relational mediation: the process of establishing and managing interpersonal relationships in order to create a positive, collaborative environment. Descriptors were also developed for other, related, areas. The article briefly summarises the three phases of validation to which the draft descriptors were subjected before being calibrated to the mathematic scale underlying the CEFR’s levels and descriptors.

    2008-08-15

    To develop and implement an elective pharmacy course that included a guided abstinence experience to illustrate addiction recovery principles. A 1-credit elective course to illustrate addiction recovery principles was developed and implemented. The course required students to give up a habit for 6 weeks that was causing them problems, meet weekly to discuss addiction recovery processes, and relate their experiences in a journal. Course grades were determined by class participation, submitted worksheets, and submission of the journal and a paper concerning their role as a pharmacist in dealing with those with addictions and in recovery. Pre- and posttests consisting of addiction case scenarios were used to assess students' application of course material. Graded course elements, pretesting and posttesting, and student course evaluations indicated that course objectives were met. Over the past 15 years, student enrollment has grown from approximately 10% of pharmacy classes to approximately 50% (average 31 students). A guided abstinence experience was an effective tool for teaching pharmacy students the concepts of addiction and recovery.

    With the invention of Ultra-Bright LED, solid state lighting has come to something which is much more efficient and energy saving when compared to conventional incandescent or fluorescent lighting. With the use of proper driver electronics now a days it is possible to install solid state lighting systems with the cost same as that of any other lighting technology. This paper is a part of the research project we are doing in our lab, which deals with using ultra bright LEDs of different colors for lighting applications. The driver electronics are made in such a way that, the color and brightness of the lights will change according to context. For instance, if one of the users is reading a story or listening to music in a Personal Computer or in a hand held device such as a PDA, the lighting systems and the HVAC (Heating Ventilation Air-conditioning) systems will change dramatically according to the content of the story or the music. The vulnerability of solid-state lighting helps to accomplish such an effect. Such a type of system will help the reader to feel the story mentally and physically as well. We developed complete driver electronics for the system using multiple microcomputers and a full software suite which uses complex algorithms to decode the context from text or music and synchronize it to lighting and HVAC information. The paper also presents some case-study statistics which shows the advantage of using the system to teach kindergarten children, deaf and dumb children and for language learning classes.

    Current research policy and strategy documents recommend applying life cycle assessment (LCA) early in research and development (R&D) to guide emerging technologies toward decreased environmental burden. However, existing LCA practices are ill-suited to support these recommendations. Barriers related to data availability, rapid technology change, and isolation of environmental from technical research inhibit application of LCA to developing technologies. Overcoming these challenges requires methodological advances that help identify environmental opportunities prior to large R&D investments. Such an anticipatory approach to LCA requires synthesis of social, environmental, and technical knowledge beyond the capabilities of current practices. This paper introduces a novel framework for anticipatory LCA that incorporates technology forecasting, risk research, social engagement, and comparative impact assessment, then applies this framework to photovoltaic (PV) technologies. These examples illustrate the potential for anticipatory LCA to prioritize research questions and help guide environmentally responsible innovation of emerging technologies.

    2006-01-01

    In volume rendering, it is very difficult to simultaneously visualize interior and exterior structures while preserving clear shape cues. Highly transparent transfer functions produce cluttered images with many overlapping structures, while clipping techniques completely remove possibly important context information. In this paper, we present a new model for volume rendering, inspired by from illustration. It provides a means of interactively inspecting the interior of a volumetric data set in a feature-driven way which retains context information. The context-preserving volume rendering model uses a function of shading intensity, gradient magnitude, distance to the eye point, and previously accumulated opacity to selectively reduce the opacity in less important data regions. It is controlled by two user-specified parameters. This new method represents an alternative to conventional clipping techniques, sharing their easy and intuitive user control, but does not suffer from the drawback of missing context information.

Our goal is to confront tickets to find similarities and differences dialogic between them. This perspective reveals the interpretations made by many readers over the years and the receptions of the English writer in different contexts and media. Our critical and theoretical reflection is based on studies of the Russian philosopher Mikhail Bakhtin about the aesthetics of literary creation and amplifies the concepts of literary cinema, collective translation and aesthetics of film creation.

    2016-01-01

    When Isaac Newton died in 1727 he left a rich legacy in terms of draft manuscripts, encompassing a variety of topics: natural philosophy, mathematics, alchemy, theology, and chronology, as well as papers relating to his career at the Mint. One thing that immediately strikes us is the textuality of Newton's legacy: images are sparse. Regarding his scholarly endeavours we witness the same practice. Newton's extensive drafts on theology and chronology do not contain a single illustration or map. Today we have all of Newton's draft manuscripts as witnesses of his working methods, as well as access to a significant number of books from his own library. Drawing parallels between Newton's reading practices and his natural philosophical and scholarly work, this paper seeks to understand Newton's recondite writing and publishing politics.

    2006-06-01

    Functional magnetic resonance imaging (fMRI) has become a popular research tool, yet its use for diagnostic purposes and actual treatment planning has remained less widespread. The literature yields rather sparse evidence-based data on clinical fMRI applications and accordant decision-making. Notwithstanding, blood oxygenation level dependent (BOLD)- and arterial spin labeling (ASL)-fMRI can be judiciously combined with perfusion measurements, electroencephalographic (EEG) recordings, diffusion-weighted imaging (DWI), and fiber tractographies to assist clinical decisions. In this article we provide an overview of clinical fMRI applications based on illustrative examples. Assessment of cochlear implant candidates by fMRI is covered in some detail, and distinct reference is made to particular challenges imposed by brain tumors, other space-occupying lesions, cortical dysplasias, seizure disorders, and vascular malformations. Specific strategies, merits, and pitfalls of analyzing and interpreting diagnostic fMRI studies in individual patients are highlighted. Copyright 2006 Wiley-Liss, Inc.

    The field of Medical and Scientific Illustration in the United States is large and constantly changing. In 1974, when the author began his studies, everything about the field was different. At the time, a student in the U.S. could go to a number of Universities (4 year) or Colleges (2 year) to study this subject. More than forty years later, only a few programs still offer similar programs of study. The Rochester Institute of Technology (RIT), where the author is a professor and Randolph Community College in North Carolina are all that remain from the more than ten that had operated. These two programs are very different from one another and there is not adequate space in this article to expand on these differences.

    2008-01-01

    This article describes the process of theoretical substruction and uses this process to examine the significance of Rosenbaum's resourcefulness theory for nursing research and practice. The article discusses relocation as a phenomenon of interest to gero-psychiatric nurses working with elders who have relocated to retirement communities, illustrated by the theory of learned resourcefulness. The literature was reviewed to assess the congruence between the theoretical and operational systems suggested by Rosenbaum's resourcefulness theory. A model of learned resourcefulness is presented that includes middle-range concepts, relational statements, and propositions derived from the research literature. Theoretical substruction provides a mechanism for testing middle-range theories that may contribute to nursing knowledge development.

    Three-way component analysis techniques are designed for descriptive analysis of 3-way data, for example, when data are collected on individuals, in different settings, and on different measures. Such techniques summarize all information in a 3-way data set by summarizing, for each way of the 3-way data set, the associated entities through a few components and describing the relations between these components. In this article, 3-mode principal components analysis is described at an elementary level. Guidance is given concerning the choices to be made in each step of the process of analyzing 3-way data by this technique. The complete process is illustrated with a detailed description of the analysis of an empirical 3-way data set.

    Full Text Available Recent high-throughput techniques have generated a flood of biological data in all aspects. The transformation and visualization of multi-dimensional and numerical gene or protein expression data in a single heatmap can provide a concise but comprehensive presentation of molecular dynamics under different conditions. In this work, we developed an easy-to-use tool named HemI (Heat map Illustrator, which can visualize either gene or protein expression data in heatmaps. Additionally, the heatmaps can be recolored, rescaled or rotated in a customized manner. In addition, HemI provides multiple clustering strategies for analyzing the data. Publication-quality figures can be exported directly. We propose that HemI can be a useful toolkit for conveniently visualizing and manipulating heatmaps. The stand-alone packages of HemI were implemented in Java and can be accessed at http://hemi.biocuckoo.org/down.php.

    The Zika virus (ZIKV) is a flavivirus of the family Flaviviridae, which is similar to dengue virus, yellow fever and West Nile virus. Recent outbreaks in South America, Latin America, the Caribbean and in particular Brazil have led to concern for the spread of the disease and potential to cause Guillain-Barré syndrome and microcephaly. Although ZIKV has been known of for over 60 years there is very little in the way of knowledge of the virus with few publications and no crystal structures. No antivirals have been tested against it either in vitro or in vivo. ZIKV therefore epitomizes a neglected disease. Several suggested steps have been proposed which could be taken to initiate ZIKV antiviral drug discovery using both high throughput screens as well as structure-based design based on homology models for the key proteins. We now describe preliminary homology models created for NS5, FtsJ, NS4B, NS4A, HELICc, DEXDc, peptidase S7, NS2B, NS2A, NS1, E stem, glycoprotein M, propeptide, capsid and glycoprotein E using SWISS-MODEL. Eleven out of 15 models pass our model quality criteria for their further use. While a ZIKV glycoprotein E homology model was initially described in the immature conformation as a trimer, we now describe the mature dimer conformer which allowed the construction of an illustration of the complete virion. By comparing illustrations of ZIKV based on this new homology model and the dengue virus crystal structure we propose potential differences that could be exploited for antiviral and vaccine design. The prediction of sites for glycosylation on this protein may also be useful in this regard. While we await a cryo-EM structure of ZIKV and eventual crystal structures of the individual proteins, these homology models provide the community with a starting point for structure-based design of drugs and vaccines as well as a for computational virtual screening.

  5. Corporal Punishment of Children: an instance of the Challenge of Cultural Relativism and the Universality of Human Rights of Children

    Full Text Available Today many countries have taken measures to recognize the values, principles, rules and norms of human rights, adopting appropriate mechanisms to ensure their implementation and monitoring through a set of documents, doctrines, practices and institutions which are known as the international system of human rights. Under this system, in light of all rules of international law related to human rights, a protection system has been established which with all its principles and institutions seeks the ways to provide general public to benefit from the common global values ​​and to ensure respect for the human beings. The development of this system and consensus on the values, principles, rules and norms of human rights provide grounds for the universality of human rights which has its roots in inherent human dignity of people all over the world more than anything else. Thereupon the development of the international system of human rights of children, special protection of children in general and against acts that violate their rights in particular, has been recognized and universally accepted. This principle has been written into the constitutions of many countries but the constitution of the Islamic Republic of Iran is yet to integrate it. Mandatory family responsibilities, differential criminalization and passing specific penalization for behaviors that violate the rights of children, are the most important illustrations of the principle of special protection of children in public welfare, civil and criminal laws. People who are involved in the child's life the most are parents. Hence, the family is the most important factor in child protection. But can such a role and relation be considered as a justification for granting special rights and privileges to parents and other caregivers and consequently pave the way for deviating from the universal principle of prohibiting discrimination against children?

    Increasingly, healthcare providers are implementing lean practices to achieve quality results. Implementing lean healthcare practices is unique compared to manufacturing and other service industries. The purpose of this paper is to present a model that identifies and defines the lean implementation key success factors in healthcare organisations. The model is based on an extant literature review and a case illustration that explores actual lean implementation in a major USA hospital located in a Midwestern city (approximately 300,000 people). An exploratory/descriptive study using observation and follow-up interviews was conducted to identify lean practices in the hospital. Lean practice key drivers include growing elderly populations, rising medical expenses, decreasing insurance coverage and decreasing management support. Effectively implementing lean practices to increase bottom-line results and improve organisational integrity requires sharing goals and processes among healthcare managers and professionals. An illustration explains the model and the study provides a sound foundation for empirical work. Practical implications are included. Lean practices minimise waste and unnecessary hospital stays while simultaneously enhancing customer values and deploying resources in supply systems. Leadership requires clear project targets based on sound front-end planning because initial implementation steps involve uncertainty and ambiguity (i.e. fuzzy front-end planning). Since top management support is crucial for implementing lean practices successfully, a heavyweight manager, who communicates well both with top managers and project team members, is an important success factor when implementing lean practices. Increasingly, green orientation and sustainability initiatives are phrases that replaced lean practices. Effective results; e.g. waste reduction, employee satisfaction and customer values are applicable to bigger competitive challenges arising both in specific

    2017-04-01

    Borderline personality disorder (BPD) has been shown to be a valid and reliable diagnosis in adolescents and associated with a decrease in both general and social functioning. With evidence linking BPD in adolescents to poor prognosis, it is important to develop a better understanding of factors and mechanisms contributing to the development of BPD. This could potentially enhance our knowledge and facilitate the design of novel treatment programs and interventions for this group. In this paper, we outline a theoretical model of BPD in adolescents linking the original mentalization-based theory of BPD, with recent extensions of the theory that focuses on hypermentalizing and epistemic trust. We then provide clinical case vignettes to illustrate this extended theoretical model of BPD. Furthermore, we suggest a treatment approach to BPD in adolescents that focuses on the reduction of hypermentalizing and epistemic mistrust. We conclude with an integration of theory and practice in the final section of the paper and make recommendations for future work in this area.

    This chapter explores iconography in neurology from the birth of photography up to the early medical applications of cinematography before 1914. The important visual part of neurological diagnosis explains why these techniques were adopted very early by neurologists. Duchenne published the first medical book illustrated with photographs of patients. The first and most famous photographic laboratory was created in Charcot's department, at the Salpêtrière in Paris, under the direction of Albert Londe. Londe published the first book dedicated to medical photography. The physiologist Marey and the photographer Muybridge, in association with neurologists, played key roles in the development of chronophotography and cinematography. Germany was the first country to welcome cinematography in a neurology department. Independently, neurologists began to film patients in other countries in Europe and in America. In 1905, Arthur Van Gehuchten (1861-1914), Belgian anatomist and neurologist, began systematically to film neurologic patients, with the intention of building up a complete neurological iconographic collection. This collection has survived and has been restored in the laboratory of the Royal Belgian Film Archive where the films are now safely stored in their vaults.

    Objective: To test whether laboratory-based research differentiating sleepwalkers (SW) from controls (C) can be applied in an uncontrolled forensic case as evidence the alleged crime was committed during an arousal from sleep in which the mind is not fully conscious due to a SW disorder. Methods: A PSG study recorded 8 months after the defendant was charged was analyzed independently by spectral analysis. Slow wave activity (SWA) and cyclic alternating pattern (CAP) rates were computed. Clinical interviews and police records were reviewed for data re: the defendant's sleep prior to the event and use of drugs, alcohol, and stimulants. Results: The SWA distribution was abnormally low and flat, significantly lower than published controls; in the first NREM cycle, CAP rate 55 was above normal. Two weeks of prior sleep deprivation was confirmed from interviews and defendant's observed daytime sleepiness. Caffeine intake the day before the event was calculated at 826 mg over 14 hours. Snoring and a mild breathing disorder were present in the PSG. Conclusion: Testimony based on spectral analysis of PSG recorded following an alleged criminal event supported a SW explanation for the non-rational behaviors charged. The defendant was acquitted of all charges and has been successfully treated. Citation: Cartwright RD; Guilleminault C. Defending sleepwalkers with science and an illustrative case.

    Full Text Available This paper deals with the emergence and development of feminism in general and feminist psychology with special emphasis on feminist's reaction to traditional assumptions in Freudian psychology and male dominated theory and research. Feminist movement simply started as a women's activism which later claimed political identity and finally ended as women's liberation movement. Feminists simply advocate gender equality. Emergence of feminist psychology movement and appearance of significant female figures in psychology is further explained along with their contribution to the theory, personality and specific developmental issues along with its input to the therapy and counseling field. The influence of four feminist philosophical approaches namely, liberal feminism, cultural feminism, radical feminism and social feminism are also shortly discussed alongside with their practical implications. Above and beyond, feminist contribution to the therapy field reflected in offering specific therapy goals are also discussed. Self esteem as a core issue and one of feminist therapy goals is finally discussed and presented through a specific case study illustration. Feminist therapy is important therapy approach with significant therapy goals contribution in relation to women's mental health issues. Consideration of sex, gender, cultural diversity, etiology, diagnosis and treatment is feminist request for successful therapy because fixing woman for functioning in a dysfunctional society seems not enough.

  14. Illustration of distributed generation effects on protection system coordination

    Science.gov (United States)

    Alawami, Hussain Adnan

    Environmental concerns, market forces, and emergence of new technologies have recently resulted in restructuring electric utility from vertically integrated networks to competitive deregulated entities. Distributed generation (DG) is playing a major role in such deregulated markets. When they are installed in small amounts and small sizes, their impacts on the system may be negligible. When their penetration levels increase as well as their sizes, however, they may start affecting the system performance from more than one aspect. Power system protection needs to be re-assessed after the emergence of DG. This thesis attempts to illustrate the impact of DG on the power system protection coordination. It will study the operation of the impedance relays, fuses, reclosers and overcurrent relays when a DG is added to the distribution network. Different DG sizes, distances from the network and locations within the distribution system will be considered. Power system protection coordination is very sensitive to the DG size where it is not for the DG distance. DG location has direct impact on the operation of the protective devices especially when it is inserted in the middle point of the distribution system. Key Words, Distributed Generation, Impedance relay, fuses, reclosers, overcurrent relays, power system protection coordination.

  15. Remote Sensing of Compact Three-Dimensional Clouds from Oblique Views, with Illustrations Using MISR Data

    Science.gov (United States)

    Davis, A. B.

    2009-12-01

    All operational cloud remote sensing targeting macro- and micro-physical properties is based on one-dimensional (1D) radiative transfer (RT) where the cloud is represented as a uniform plane-parallel slab. For instance, Terra's MODIS cloud data processing algorithms are grounded in 1D RT. Although that approximation may be reasonable for stratiform clouds, it fails fundamentally for horizontally finite and vertically developed cumulus-type clouds where the RT is inherently 3D at the cloud scale. The plane-parallel model is favored because it is simple and computationally tractable. As it turns out, there are 3D cloud geometries with analytically tractable solar RT (in the diffusion limit) that have been largely overlooked: the proverbial sphere (cf. URL below), elongated cylinders, and all other forms of ellipsoids. Moreover, thanks to a decade or so of progress following Moore's law, numerical methods in 3D RT have become a viable alternative to the efficiency of 1D RT. Most importantly, 3D RT and viewing geometry enable completely new ways of determining cloud properties. For instance, it can be shown that, in the absence of absorption, the ratio of overall reflected flux R to overall transmitted flux T(=1-R) increases linearly with their optical thickness τ. For 3D clouds, τ is measured along a diameter or be redefined as an average over the cloud volume perpendicularly to the solar illumination. This simple "R/T ~ τ" law can be generalized to arbitrarily shaped internally uniform clouds with sufficient opacity. Note that the R vs. T partition is based here on the illuminated/shaded separation at the terminator line, and not on angle away from the vertical as is customary in climate studies. Can we thus break away from the old 1D RT paradigm? Terra's ASTER sensor can be tasked to image finite clouds and has resolution (15 m) such that pixels will have either purely transmitted light or purely reflected light depending on which side of the cloud's terminator

    2017-04-01

    Full Text Available BACKGROUND EEG or Electroencephalogram, which is the most important diagnostic procedure to evaluate Epilepsy patients, may sometimes fall short of accurate sensitivity and may require few Activation Procedures such as ‘Hyperventilation’ and ‘Sleep’ to bring out the active changes of an Epileptic brain. The present study was done with the aim of knowing the efficacy of such Activation Procedures like ‘Hyperventilation’ and ‘Sleep’ in illustrating the EEG wave pattern changes of an Epileptic brain during the interictal period. MATERIALS AND METHODS The present study was done in the Department of Physiology in association with the Department of Neurology, Assam Medical College & Hospital, Dibrugarh, Assam from June 2014 to May 2015. ‘113’ clinically diagnosed cases of Epilepsy were studied and analysed through Electroencephalogram using the internationally accepted 10-20 electrode placement method. Hyperventilation was used in 28 Epilepsy cases and Sleep was used in 14 Epilepsy cases. History & Physical examination findings were recorded in a Proforma. Chi-square analysis was done through GraphPad Prism 6 software to assess the significance of the activation procedures used. RESULTS Our study found that EEG of 42 cases out of the total 113 cases required Activation Procedures to elicit the wave pattern changes of the Epileptic brain. Hyperventilation was helpful in adult age group and sleep was useful in children age group. Hyperventilation had overall 53.57% sensitivity in detecting Epilepsy, and Sleep had 64.29% sensitivity in detecting Epilepsy. Hyperventilation was specifically helpful to elicit absence seizures where it had 75% sensitivity. CONCLUSION The sensitivity of EEG in detecting Epilepsy can thus be increased by using activation procedures like sleep & Hyperventilation to ensure that no epilepsy cases are missed out in diagnosis & treatment.

    This report describes the procedure for generating input models of a one-dimensional kinetics code, HAMOCE, and also provides the method and model verification results through a series of illustrative sample calculations. The primary component of a HAMOCE model is the one-dimensional (1D) group constants which are obtained through radial collapsing. It is thus necessary to generate raw group constant data by three-dimensional static calculations at various reactor conditions and then functionalize these 1D group constants. Chapter 2 first provides the definitions and functionalization schemes of the 1D group constants and describes the procedure for generating and verifying them. This procedure includes the methods for specifying the calculation condition and ranges of the base code MASTER and also for executing the 1D group constant processing code GENDA1D, which actually produces and verifies the group constant file. Chapter 3 describes the HAMOCE model generation procedure with practical examples for the SMART core application. In case of SMART, the core inlet temperature varies depending on the power level and employs a unique CEA moving sequence. These characteristics of SMART are reflected in the 1-D group constant generation. The verification results obtained for the hot full power steady state and a load follow simulation indicate that HAMOCE agrees with the reference MASTER very well as long as the inlet temperature variation is excluded. This proves that the HAMOCE methodology including the group constant functionalization scheme works properly. If the inlet temperature variation is allowed, the error increases. However, the magnitude is still small enough (<100 pcm). Chapter 4 explains the coupled calculation of a system code TASS and HAMOCE. This explanation includes a brief introduction of the coupled calculation method and the initialization procedure. The applications to a power maneuvering and a cold zero power rod withdrawal indicates that the TASS

    Shainberg, D

    1976-07-01

    A case is presented of a patient telepathically perceiving a stressful event in the analyst's life. Evidence for this is a dream of the patient that embodied a similar content and affect. It is hypothesized that the patient's telepathic ability derived from his self-effacing character trend, which determines an act of perception.

  20. Bregman Clustering for Separable Instances

    Science.gov (United States)

    Ackermann, Marcel R.; Blömer, Johannes

    The Bregman k-median problem is defined as follows. Given a Bregman divergence D φ and a finite set P subseteq { R}^d of size n, our goal is to find a set C of size k such that the sum of errors cost(P,C) = ∑ p ∈ P min c ∈ C D φ (p,c) is minimized. The Bregman k-median problem plays an important role in many applications, e.g., information theory, statistics, text classification, and speech processing. We study a generalization of the kmeans++ seeding of Arthur and Vassilvitskii (SODA '07). We prove for an almost arbitrary Bregman divergence that if the input set consists of k well separated clusters, then with probability 2^{-{O}(k)} this seeding step alone finds an {O}(1)-approximate solution. Thereby, we generalize an earlier result of Ostrovsky et al. (FOCS '06) from the case of the Euclidean k-means problem to the Bregman k-median problem. Additionally, this result leads to a constant factor approximation algorithm for the Bregman k-median problem using at most 2^{{O}(k)}n arithmetic operations, including evaluations of Bregman divergence D φ .

    soluciones se deben basar en acuerdos entre los investigadores y los participantes.Considering advancements in data collection methods, we explore the use of videotaping in qualitative research. This bibliographical study aims at developing reflections on the possibilities of using videotapes in research and at providing material to researchers. The video is used as an instrument of data collection and generation. We mention technical aspects, such as the utilization of a mobile or fixed camera. By means of the latter, the authors report their experience, emphasizing compliance with the neutrality principle and the possibility of editing the images obtained as a means of generating new data. The authors highlight that it was possible to detect contradictions between discourse and behavior through the use of videotaping and interviews. The authors also discuss the ethical principles set by CNS Resolution 196/96 and other ethical questions, whose solutions should be based on the agreement between researchers and subjects.

    Full Text Available The theme of this study is pictorial representation of costume and fashion in painting, fashion plates and fashion illustrations. Fashion illustration of the 20th century, specific in terms of freedom of interpretation that is given to the artists when representing fashion trends, has kept those elements of painting that are almost lost in contemporary art movements (for instance figuration. Through several specific examples in art history I will try to demonstrate the artist’s approach to the representation of costume. In this study I will also try to define the role of painting when it comes to the fashion, the role of fashion plates and then the role of fashion illustration created in the early 20th century. Finally, I will take a look at the fashion photography that in the beginning has found its role-models precisely in the fashion illustration and today is returning to the visual characteristics of renaissance art, and to the painting in general, from which everything has begun.

  3. Unveiling the Nature of Charge Carrier Interactions by Electroabsorption Spectroscopy: An Illustration with Lead-Halide Perovskites.

    Unravelling the nature of the interactions between photogenerated charge carriers in solar energy conversion devices is key to enhance performance. In this perspective, we discuss electroabsorption spectroscopy (EAS), as the spectral bandshape of the electroabsorption (EA) signal directly depends on the strength of the charge carrier interactions. For instance, the electroabsorption response in molecular or confined excitonic systems can be modelled perturbatively yielding the Stark effect. In contrast, most solids exhibit weaker interactions, and a perturbative approach cannot be taken in general. For solids with negligible charge carrier interactions, one resorts to the Franz-Keldysh theory of a continuum in a field, that, in the low-field limit, simplifies to the low-field FKA effect. Alternatively, when the continuum approximation breaks down, the problem of a Wannier exciton in a field has to be solved, and numerical methods emerged as the best solution. We illustrate our discussion with two examples involving lead-halide perovskites, a new, high-stake solar cell material. In the first example, we discuss the lineshape of the electroabsorption response for thin-films of lead-iodide perovskite, that sustains the photogeneration of free carriers. In the second example, we address a confined excitonic case with lead-bromide perovskite nanoparticles, and demonstrate the presence of so-called charge-transfer excitons.

    Full Text Available The Catharanthus roseus plant is the source of many valuable terpenoid indole alkaloids (TIAs, including the anticancer compounds vinblastine and vincristine. Transcription factors (TFs are promising metabolic engineering targets due to their ability to regulate multiple biosynthetic pathway genes. To increase TIA biosynthesis, we elicited the TIA transcriptional activators (ORCAs and other unidentified TFs with the plant hormone, methyl jasmonate (MJ, while simultaneously silencing the expression of the transcriptional repressor ZCT1. To silence ZCT1, we developed transgenic hairy root cultures of C. roseus that expressed an estrogen-inducible Zct1 hairpin for activating RNA interference. The presence of 17β-estradiol (5μM effectively depleted Zct1 in hairy root cultures elicited with MJ dosages that either optimize or inhibit TIA production (250 or 1000μM. However, silencing Zct1 was not sufficient to increase TIA production or the expression of the TIA biosynthetic genes (G10h, Tdc, and Str, illustrating the tight regulation of TIA biosynthesis. The repression of the TIA biosynthetic genes at the inhibitory MJ dosage does not appear to be solely regulated by ZCT1. For instance, while Zct1 and Zct2 levels decreased through activating the Zct1 hairpin, Zct3 levels remained elevated. Since ZCT repressors have redundant yet distinct functions, silencing all three ZCTs may be necessary to relieve their repression of alkaloid biosynthesis.

    To examine the content of Dutch practice nurses' (PNs') advices about weight, nutrition and physical activity to overweight and obese patients. A 100 videotaped real-life PN consultations (The Netherlands, 2010/2011) with overweight or obese patients were selected. An observational checklist was developed to assess frequency and content. Personalization of advices was scored, as also the guidelines on which PNs based their advices. Content analysis was used to identify different categories of advices. About one quarter of advices concerned weight, over two-thirds nutrition and one-third physical activity. Lose weight, eat less fat and be more physically active in general were the main categories for each type of advice. Despite high clarity of advices, lower scores were found for specificity and personalization. Very few nutrition advices were provided in combination with physical activity advices. Weight advices often related to the patient's complaint. PNs seldom set a concrete weight goal. Although benefits of physical activity were discussed, often no practical advices were provided about how to achieve this. Integrated lifestyle advice was not common: advices about nutrition and physical activity were fragmented throughout the consultation. Obesity prevention needs more emphasis in PNs' educational programs.

  10. Reconstruction in A Two-Person World May Be More About The Present Than The Past: Freud and The Wolf Man, an Illustration.

    Science.gov (United States)

    Gottlieb, Richard M

    2017-04-01

    The psychoanalytic process of reconstruction has yet to be examined from the perspective of today's two-person psychologies. Earlier writers on the subject have implicated the analyst and his emotional involvement as influences that may distort the valid recovery of memories, while others have written that the transference and the reconstructed past are interdependent. By contrast with both views, it is suggested here that the reconstructed product itself may reflect the transference-countertransference engagement of the dyad: in some instances, and to some extent in all instances, the scene or story of the presumed past will be a version of the current analytic relationship. In certain cases consideration of the conscious and unconscious emotional entanglements of the dyad will reveal that the reconstruction says more about the analytic present than about the past. Freud's Wolf Man case provides a good illustration of this point. While a broad consensus exists that its famous primal scene reconstruction cannot be veridical, it has most often been dismissed as distorted by Freud's theoretical commitments. A closer examination of the relationship between Freud and Pankejeff reveals that the reconstruction is an accurate rendering of warded-off aspects of the dyad's way of being together. The potential clinical utility of adopting this perspective is that it encourages the analyst to reflect on his clinical reconstructions, interrogating them for clues to otherwise elusive aspects of the current clinical relationship.

    This report describes a computer program for drawing crystal structure illustrations. Ball-and-stick type illustrations of a quality suitable for publication are produced with either spheres or thermal-motion probability ellipsoids on the atomic sites. The program can also produce stereoscopic pairs of illustrations which aid in the visualization of complex packing arrangements of atoms and thermal motion patterns. Interatomic distances, bond angles, and principal axes of thermal motion are also calculated to aid the structural study.

  12. Design Support System for Coloring Illustrations by Using the Colors Preferred by a User as Determined from the Hue Patterns of Illustrations Prepared by that User

    Fukai, Hironobu; Mitsukura, Yasue

    We propose a new design support system that can color illustrations according to a person's color preferences that are determined on the basis of the color patterns of illustrations prepared by that person. Recently, many design tools for promoting free design have been developed. However, preferences for various colors differ depending on individual personality. Therefore, a system that can automatically color various designs on the basis of human preference is required. In this study, we propose an automatic modeling system that can be used to model illustrations. To verify the effectiveness of the proposed system, we simulate a coloring design experiment to determine the color patterns preferred by some subjects by using various design data. By using the design data, we determine each subjects preferred color pattern, and send feedback on these individual color patterns to the proposed system.

    We present a system that detects cancer on slides of gastric tissue sections stained with hematoxylin and eosin (H&E). At its heart is a classi er trained using the semi-supervised multi-instance learning framework (MIL) where each tissue is represented by a set of regions-of-interest (ROI) and a single label. Such labels are readily obtained because pathologists diagnose each tissue independently as part of the normal clinical work ow. From a large dataset of over 26K gastric tissue sections from over 12K patients obtained from a clinical load spanning several months, we train a MIL classi er on a patient-level partition of the dataset (2/3 of the patients) and obtain a very high performance of 96% (AUC), tested on the remaining 1/3 never-seen before patients (over 8K tissues). We show this level of performance to match the more costly supervised approach where individual ROIs need to be labeled manually. The large amount of data used to train this system gives us con dence in its robustness and that it can be safely used in a clinical setting. We demonstrate how it can improve the clinical work ow when used for pre-screening or quality control. For pre-screening, the system can diagnose 47% of the tissues with a very low likelihood (cancers, thus halving the clinicians' caseload. For quality control, compared to random rechecking of 33% of the cases, the system achieves a three-fold increase in the likelihood of catching cancers missed by pathologists. The system is currently in regular use at independent pathology labs in Japan where it is used to double-check clinician's diagnoses. At the end of 2012 it will have analyzed over 80,000 slides of gastric and colorectal samples (200,000 tissues).

  19. Process Philosophy and the Text-Image Interface: A Study of Three Western Australian Botanical Illustrators

    Directory of Open Access Journals (Sweden)

    John Charles Ryan

    2012-12-01

    Full Text Available Botanical illustration combines scientific knowledge and artistic technique. However, whereas illustrated botanical images record static visual qualities, such as form and color, written botanical narratives supply crucial sensory, ecological, historical, and cultural contexts that complement visual representation. Understanding the text-image interface—where images and words intersect—contributes to humanities-based analyses of botanical illustration and illustrators. More specifically, a process philosophy perspective reveals the extent to which botanical representations engage the temporality, cyclicality, and contextuality of the living plants being illustrated. This article takes up these themes through a comparative theoretical study of three female Western Australian botanical illustrators, Georgiana Leake (1812–1869, Emily Pelloe (1877–1941, and Philippa Nikulinsky (born 1942, whose lives together span the 183 year history of the Swan River Colony and the state of Western Australia. I apply a processist framework to examine the text-image interface of their works. All three illustrators use some form of textuality: marginalia, annotations, written accompaniments, introductory statements, and other narrative materials. In examining their written commentaries and traces, I identify the emergence of a process mode of botanical illustration that represents plants as ecological, historical, cultural, and temporal organisms.

If the argument is construed as an instance of the Law of Likelihood, nothing follows with regard to the probability that Lucia was a serial killer. If, however, the Argument from Coincidence may be interpreted charitably as an instance of Bayesian updating, the Court of The Hague did not fathom the diversity of the data needed in order to make it sound. Clearly, the Court had an insufficient grasp of the logic involved in the Coincidence Argument. Since this example is not atypical, I recommend law faculties to include probability logic (inter alia in their courses on legal reasoning.

  14. Revisiting Max Brödel's 1939 classic coronal illustration of the ear.

    To create an anatomically more accurate coronal schematic illustration of the ear. Analysis of Max Brödel's 1939 classic coronal depiction of the ear including the story of its creation. Utilization of high-resolution CT images and 3D digital models of the temporal bone to create an updated and more anatomically accurate illustration. For nearly 7 decades, Brödel's beautiful illustration has served as the inspiration for innumerable textbook and article illustrations. In his design, the artist intentionally choose to diverge from literal anatomy in that he distorted some structures (such as the cochlea and posterior semicircular canal) to bring them into greater prominence and clarity and eliminated others (such as the carotid artery) to avoid a cluttered image. Numerous anatomic errors exist such as a 180-degree reversal of the incus and a markedly foreshortened internal auditory canal. Brödel's illustration has been routinely imitated by subsequent illustrators (in collaboration with otologists) and virtually all have faithfully reproduced Brödel's artistic distortions and inadvertent errors in their depictions--often with the assumption that they represented actual anatomy rather than an artistic interpretation. It is hoped that adoption of a more anatomically accurate standard coronal schematic of the ear will enhance the clarity and precision of future illustrations in the otologic literature.

  15. OR TEP-II: a FORTRAN Thermal-Ellipsoid Plot Program for crystal structure illustrations

    Energy Technology Data Exchange (ETDEWEB)

    Johnson, C.K.

    1976-03-01

    A computer program is described for drawing crystal structure illustrations using a mechanical plotter. Ball-and-stick type illustrations of a quality suitable for publication are produced with either spheres or thermal-motion probability ellipsoids on the atomic sites. The program can produce stereoscopic pairs of illustrations which aid in the visualization of complex packing arrangements of atoms and thermal motion patterns. Interatomic distances, bond angles, and principal axes of thermal motion are also calculated to aid the structural study. The most recent version of the program, OR TEP-II, has a hidden-line-elimination feature to omit those portions of atoms or bonds behind other atoms or bonds.

  17. The Illustrious Anatomist: Authorship, Patronage, and Illustrative Style in Anatomy Folios, 1700-1840.

    Science.gov (United States)

    Berkowitz, Carin

    2015-01-01

    A number of anatomists working in the period 1700-1840 used expensive illustrated books to depict their greatest scientific work, establish priority of discovery for posterity, and enlist patrons. These anatomists drew on the grand traditions of anatomical illustration and asserted their right to a place within that history. But with artists mediating the expression of anatomists' vision, it was important that an anatomist assert his control over the illustrations commemorating his expertise. Anatomists used stylistic signatures to signal that a work was their own. Very different styles of illustration in the works of different anatomists, therefore, were made easily recognizable, and sometimes a single artist adopted notably different styles for different anatomists who employed him. Style became a marker of authorship, identifiable with the anatomist, even when he employed an artist to do the drawing and engraving, and it was also an important method of appealing to patrons.

    2011-07-01

    Max Brödel is considered the father of modern medical illustration. This report reviews his contributions to neurosurgery as a medical illustrator. Max Brödel, a young artist from Leipzig, Germany, was hired at Johns Hopkins Hospital in 1894, where he illustrated an operative textbook of gynecology for Howard A. Kelly. Although Brödel did not have any formal medical training, he quickly acquired knowledge of anatomy, pathology, physiology, and surgery. Brödel's extraordinary illustrations were characterized by an aerial perspective that conveyed the surgeon's operative viewpoint and precise surgical anatomy. He masterfully incorporated tissue realism with cross-sectional anatomy to accentuate concepts while maintaining topographical accuracy. Brödel's reputation spread quickly and resulted in collaborations with prominent surgeons, such as Cushing, Halsted, and Dandy. Cushing, who also possessed artistic talent, became a pupil of Brödel and remained a very close friend. In 1911, Brödel was appointed the director of the Department of Art as Applied to Medicine at Johns Hopkins, the first academic department of its kind in the world. For the next several decades, he trained generations of renowned medical illustrators. Just as Osler, Halsted, and Cushing passed their skills and knowledge to future leaders of medicine and surgery, Brödel did the same for the field of medical illustration. The advancement of neurosurgical education has been greatly facilitated by Max Brödel's artistic contributions. His unique ability to synthesize art and medicine resulted in timeless illustrations that remain indispensable to surgeons. The art produced by his legacy of illustrators continues to flourish in neurosurgical literature today.

    To determine patients' preferences for, and understanding of, FRAX® fracture risk conveyed through illustrations. Drawing on examples from published studies, four illustrations of fracture risk were designed and tested for patient preference, ease of understanding, and perceived risk. We enrolled a convenience sample of adults aged 50 and older at two medical clinics located in the Midwestern and Southern United States. In-person structured interviews were conducted to elicit patient ranking of preference, ease of understanding, and perceived risk for each illustration. Most subjects (n = 142) were female (64%), Caucasian (76%) and college educated (78%). Of the four risk depictions, a plurality of participants (37%) listed a bar graph as most preferred. Subjects felt this illustration used the stoplight color system to display risk levels well and was the most "clear," "clean," and "easy to read". The majority of subjects (52%) rated the pictogram as the most difficult to understand as this format does not allow people to quickly ascertain their individual risk category. Communicating risk to patients with illustrations can be done effectively with clearly designed illustrations responsive to patient preference. ClinicalTrials.gov Identifier: NCT01507662.

  6. The Cucurbitaceae and Solanaceae illustrated in medieval manuscripts known as the Tacuinum Sanitatis

    2009-01-01

    Background and Aims Beginning in the last two decades of the 14th century, richly illuminated versions of the Tacuinum Sanitatis, the Latin translation of an 11th-century Arabic manuscript known as Taqwim al-Sihha bi al-Ashab al-Sitta, were produced in northern Italy. These illustrated manuscripts provide a window on late medieval life in that region by containing some 200 full-page illustrations, many of which vividly depict the harvest of vegetables, fruits, flowers, grains, aromatics and medicinal plants. Our objective was to search for and identify the images of taxa of Cucurbitaceae and Solanaceae. Methods We have located all reported illustrated Tacuinum Sanitatis and similar or related manuscripts, searched through printed or electronic reproductions of them, categorized six of them that display full-page illustrations as archetypic, and established the identity of the Cucurbitaceae and Solanaceae appearing in these six manuscripts. Key Results and Conclusions Of the Cucurbitaceae, Cucumis sativus (short-fruited cucumbers), Cucumis melo (including round as well as elongate melons), Citrullus lanatus (both sweet watermelons and citrons), and Lagenaria siceraria (including bottle-shaped as well as long gourds), are illustrated. Of the Solanaceae, Solanum melongena (egg-shaped purple aubergines) and Mandragora sp. (mandrake) are illustrated. These depictions include some of the earliest known images of cucumber, casaba melon (Cucumis melo Inodorous Group) and aubergine, each of which closely resembles an extant cultivar-group or market type. Overall, the botanically most accurate images are in the version of the Tacuinum located in the Österreichische Nationalbibliothek, Vienna, cod. ser. n. 2644. Similarities and differences in botanical accuracy among the images of Cucurbitaceae and Solanaceae in the six archetypal Tacuinum manuscripts suggest to us that another illustrated Tacuinum, now lost, may have antedated and served as a model or inspiration for the

  8. Medieval and Renaissance anatomists: the printing and unauthorized copying of illustrations, and the dissemination of ideas.

    Lanska, Douglas J; Lanska, John Robert

    2013-01-01

    The vanguard that began to question Galenic anatomical dogma originated in northern Italy in the latter half of the thirteenth century, and not coincidentally this was where human dissection was introduced, which in turn eventually fostered the origins of realistic anatomical illustration in the late fifteenth century. With the advent of the printing press and moveable type at this time, printed books began to supersede hand-copied medieval manuscripts, and labor-intensive techniques were soon developed to integrate text and illustrations on the printed page. The same technology was used to pirate the illustrations of prior authors with varying fidelity. Specific medieval and Renaissance anatomical illustrations can often be traced from their inceptions through different stages of development to the final printed images, and then through subsequent pirated versions in various abridgements or other compendia. The most important milestone in the development of anatomy and anatomical illustration was the publication in 1543 by Andreas Vesalii of De humani corporis fabrica (On the Fabric of the Human Body), commonly referred to simply as the Fabrica. With this work, Vesalii succeeded in coordinating a publication production team (author, artists, block cutters, publisher, and typesetters) to achieve an unprecedented integration of scientific discourse, medical illustration, and typography. However, despite Vesalii's valiant efforts to prevent unauthorized duplication, the illustrations from the Fabrica were extensively plagiarized. Although Vesalii found such piracy frustrating and annoying, the long-term effect was to make Vesalii's ideas known to a wider readership and to help solidify his own revolutionary contributions to anatomy. © 2013 Elsevier B.V.

  9. ‘To the great public’: The Architectural Image in the Early Illustrated London News

    Directory of Open Access Journals (Sweden)

    Anne Hultzsch

    2017-12-01

    Full Text Available The 'Illustrated London News', launched in May 1842 as the first illustrated newspaper and quickly copied across Europe, North America and beyond, was full of architectural images. New buildings, ancient ruins, construction sites, royal visits, wars, theatre performances, exotic expeditions, historical essays and innumerable other subjects gave occasion to feature the built, whether for its own sake or as background setting. Images and texts were produced and consumed with an urge and at a speed never seen before. The building, through the illustrated press, left the static confines of the book and the framed print and became peopled by the purposeful bourgeoisie. Through a close analysis of a range of articles on the new Royal Exchange, the refurbished London Colosseum as well as the Queen’s Scotland tour, this essay explores the role of the architectural image in the illustrated press by focusing on its relationship to the accompanying text. Untangling the mechanics of representation and perception, it identifies modes of intellectual, affective, and kinetic vision through which architecture was represented to the remote reading public. By externalising and stabilising vision, the 'Illustrated London News' thus created a virtual public sphere in which the dramatic technological and material changes occurring in the period could be absorbed and normalized.

  10. Generalized Framework and Algorithms for Illustrative Visualization of Time-Varying Data on Unstructured Meshes

    Energy Technology Data Exchange (ETDEWEB)

    Alexander S. Rattner; Donna Post Guillen; Alark Joshi

    2012-12-01

    Photo- and physically-realistic techniques are often insufficient for visualization of simulation results, especially for 3D and time-varying datasets. Substantial research efforts have been dedicated to the development of non-photorealistic and illustration-inspired visualization techniques for compact and intuitive presentation of such complex datasets. While these efforts have yielded valuable visualization results, a great deal of work has been reproduced in studies as individual research groups often develop purpose-built platforms. Additionally, interoperability between illustrative visualization software is limited due to specialized processing and rendering architectures employed in different studies. In this investigation, a generalized framework for illustrative visualization is proposed, and implemented in marmotViz, a ParaView plugin, enabling its use on variety of computing platforms with various data file formats and mesh geometries. Detailed descriptions of the region-of-interest identification and feature-tracking algorithms incorporated into this tool are provided. Additionally, implementations of multiple illustrative effect algorithms are presented to demonstrate the use and flexibility of this framework. By providing a framework and useful underlying functionality, the marmotViz tool can act as a springboard for future research in the field of illustrative visualization.

    2006-04-01

    Full Text Available This article aims to investigate dictionary users’ needs for illustrative examples. A questionnaire was administered to 367 Chinese EFL learners. It was found that Chinese EFL learners use illustrative examples mainly in production and sometimes in reception. More than 60% of the subjects favor sentence examples over phrasal ones. According to them, the priority of exemplification should be given to verbs, phrasal verbs, polysemous words, ambiguous words and unmarked high-frequency vocabulary. Some of them made some valuable suggestions, such as control of unfamiliar words in illustrative examples and exemplification of derivatives. The findings in the questionnaire survey cast light on users’ needs for examples, and serve as reference for lexicographers.

  13. Making expert knowledge through the image: connections between antiquarian and early modern scientific illustration.

    Science.gov (United States)

    Moser, Stephanie

    2014-03-01

    This essay examines drawings of antiquities in the context of the history of early modern scientific illustration. The role of illustrations in the establishment of archaeology as a discipline is assessed, and the emergence of a graphic style for representing artifacts is shown to be closely connected to the development of scientific illustration in the seventeenth and early eighteenth centuries. The essay argues that the production of conventionalized drawings of antiquities during this period represents a fundamental shift in the approach to ancient material culture, signifying the recognition of objects as evidence. As has been demonstrated in other scientific fields, the creation of a visual system for recording objects was central to the acceptance of artifacts as "data" that could be organized into groups, classified as types, and analyzed to gain knowledge of the past.

    Engle, David; Holiman, Marjorie

    2002-02-01

    The case of Victoria illustrates psychotherapy with a woman faced with a difficult and unexpected divorce. The authors present a summary of typical struggles faced by Victoria through three phases of therapy. The therapy focused initially on coping with the divorce, then moved to work on her career dissatisfaction, and finally to her efforts to develop a new relationship. The case presentation illustrates resistance as it manifested itself in both a behavioral manner and as in-session resistance to awareness of internal states. The behavioral mode of resistance is manifested by her inability to follow through on decisions made in therapy sessions and by her interruptions of ongoing therapy. A transcript of a typical in-session exchange illustrates the resistance to awareness. The authors also describe interventions intended to work with the resistance.

  16. Turning art into mere illustration: concretizing art renders its influence context dependent.

    Science.gov (United States)

    Hagtvedt, Henrik; Patrick, Vanessa M

    2011-12-01

    Broadly speaking, artworks are accorded a special significance and are recognized as powerful communication tools. In the current research, the authors posit that the "specialness" of artworks may be diminished simply by emphasizing that which is depicted in them. This emphasis results in the artwork being viewed as a mere illustration rather than a work of art. Specifically, the influence of an "artwork as art" is context independent, but the influence of an "artwork as illustration" is context dependent. The authors demonstrate this phenomenon in two experiments, in the context of products associated with artworks. In a third experiment, they further demonstrate that an abstract (concrete) mind-set aligns with the influence of an artwork as art (illustration).

    The principles of interprofessional collaborative practice (IPCP) are illustrated through the case of Mary, a child with severe disabilities. Mary's experiences from early childhood to young adulthood are highlighted by both optimal and less-than-ideal examples of clinical services and collaborative practice. The range of collaboration illustrates potential variations in service delivery. Thematic comments and resources are provided by professionals experienced with and committed to IPCP who represent the following four disciplines: occupational therapy, physical therapy, special education, and speech-language pathology. Although potentially challenging, IPCP is a dynamic practice methodology appropriate for speech-language pathologists and others serving persons with severe disabilities.

  19. From La Meduse to the Titanic: Gericault’s Raft in Journalistic Illustration up to 1912

    Directory of Open Access Journals (Sweden)

    Tom Gretton

    2013-04-01

    Full Text Available This essay discusses the practices of journalistic illustration in nineteenth-century weekly illustrated magazines in London: magazines such as the 'Illustrated London News 'and the 'Graphic'. It focuses on the way that Géricault’s schema for representing shipwreck survivors in rafts and boats, mostly in the processes of rescue, was a resource for journalistic illustration in London. It concentrates on the period after 1880, ending with a discussion of the presence of ‘The Raft’ in reports of the 'Titanic'’s sinking. The essay considers some of the ways in which Géricault’s schema may have been a resource in the mythopoetic response to the 'Titanic' disaster.   The essay discusses the persistence of hand-made illustrations in the period of the ‘domestication’ of the half-tone screen (from the 1890s onwards, which introduced the photographic image (as distinct from hand-drawn or wood-engraved images derived from photographs into magazine illustration. In doing this it engages with the ways in which the coexistence of (half-tone accounts of hand-made pictures and of (half-tone accounts of photographs in the pages of magazines of the 'ILN' genre destabilized the truth-effects of hand-made illustration and threw the relative lack of affective power of the reportorial photograph into relief. It also discusses the implications for journalistic illustration of the difference between the telegram-speed ‘global-village-ization’ of the news community in the last quarter of the nineteenth century and the ‘snail-mail’ speed of transoceanic communication of pictures, until after the end of the First World War.   The essay aligns the picture-making logic of journalistic illustration with that of easel painting, to think about both these visual-culture-production milieux in terms of the manipulation of inherited visual resources, on the one hand in the praxis of picture-making, and on the other in pursuit of visible intertextualities
