Best-basis analysis of broadband tremor signals

Active volcanoes usually generate highly non-stationary broadband tremor signals. Short-time shock events with a frequency content of several decades are superimposed on a stationary narrow band continuous tremor. Tremor signals of this type can be observed in the near field of many active volcanoes. In this paper we will demonstrate the analysis of such signals using a specific tremor signal of Mt. Stromboli (Sicily). We used the Best-Basis Algorithm (BBA) in order to compute a spectrogram which is adapted to signal properties on highly different scales. It turns out that the BBA can reveal better fitting properties of the tremor in the time-frequency plane compared to standard methods like Short-Time Fourier Transformation (STFT). Moreover, this very effective algorithm can be used for real time monitoring in the time-frequency plane, for data compression or for de-noising of the tremor signals.
Efficient Incremental Induction of Decision Lists. Can Incremental Learning Outperform Non-Incremental Learning?

Abstract : Although incremental learning has many advantages in theory, it is not in practice as widely used as non-incremental learning for real-world applications. One major reason for this situation is the lack of incremental algorithms that can perform as fast as non-incremental algorithms in general. In this paper, we present an effective yet very efficient incremental algorithm CDM for learning decision lists whose complexity is O(dn(2)), where d is the number of attributes and n the number of training instances. On the experiments we have conducted, CDLA's performance is as fast and accurate as the best non-incremental learning algorithms for batch tasks, and is much faster than the best-known incremental and non-incremental learning algorithms for serial tasks. We also show that efficient incremental algorithms can provide new research opportunities for learners to actively select training instances for better accuracy and higher speed, and that incremental learning may eventually outperform non-incremental learning in many aspects.
Conception d'antennes souples et de conducteurs magnétiques artificiels en bande UHF

L'invention de l'antenne fut a la base de la creation des communications sans fil a l'oree du XXe siecle. A l'origine des objets metalliques destines a transmettre et recevoir des ondes electromagnetiques, les antennes n'ont cesse de se complexifier pour satisfaire l'impressionnant developpement des communications sans fil. C'est dans ce contexte qu'est ne le concept d'antenne « wearable » il y a moins de deux decennies ouvrant un nouveau champ de recherche sur les antennes souples. C'est dans ce cadre que ce travail de these se consacre a la conception d’antennes souples en bande UHF.Une premiere etude a permis de concevoir une antenne Vivaldi antipodale [150 - 900 MHz] souple pour la Section Technique de l'Armee de Terre. Six de ces antennes sont destinees a etre placees sous un ballon gonfle a l'helium pour receptionner des signaux RF.Une seconde etude est effectuee en collaboration avec la societe Syrlinks et le CNES. L'objectif du projet est de concevoir des antennes souples pour le suivi de personnes avec le systeme ARGOS (401 et 466 MHz). La solution retenue est une PIFA planaire de largeur inferieure a lambda/3. Elle a l'avantage d'etre fine et legere. Le materiau souple employe est un caoutchouc silicone selectionne parmi plusieurs materiaux souples grâce a des caracterisations dielectriques. Cependant, le probleme de cette antenne est qu'elle possede un rayonnement quasi-omnidirectionnel. Etant donne qu'il n'etait pas envisageable d'utiliser un plan reflecteur metallique pour des raisons de dimensions, il a ete decide de concevoir un conducteur magnetique artificiel (CMA) souple. Toutefois, la conception de CMA dans le bas de la bande UHF se heurte a des difficultes de miniaturisation. Pour contourner ce probleme, il a ete developpe deux concepts de CMA a cellules unitaires de faibles dimensions devant la longueur d'onde. La premiere solution utilise des capacites interdigitees et la seconde une structure double couche. Pour ces deux concepts, un modele circuit est propose et valide par des mesures experimentales. Les mesures de l'association CMA - antenne montrent une bande passante suffisante pour des applications ARGOS et un rayonnement majoritairement dirigee dans la direction oppose a celle du CMA.
Poverty, Diet and Health Behaviours: a Quantitative and Qualitative Study Among Young Urbanised Women.

Demographic, socio-economic, attitudinal, dietary, health behavioural and anthropometric data were collected from 221 “disadvantaged” and 74 “advantaged” women aged 18-35 years across Dublin, according to the provisions of a novel socio-economic sampling frame. Internal and external validation techniques established the dietary assessment method of choice and identified “valid” dietary reporters (n=216, 153 disadvantaged, 63 advantaged) among this sample. Five qualitative focus groups (n=5-8 per group) were also conducted among disadvantaged women to examine their diet and health behaviour choices. Lower intakes of fruit & vegetables (172g/d vs. 405g/d, p<0.001), breakfast cereals (4g/d vs. 29g/d, p<0.001), fish (0g/d vs. 26g/d, p<0.001) and dairy products (166g/d vs. 228g/d, p=0.001), and higher intakes of meat and meat products (184g/d vs. 143g/d, p<0.001) and potatoes and potato products (165g/d vs. 77g/d, p<0.001), were observed among the disadvantaged versus the advantaged women. Non-compliance with carbohydrate (49% vs. 30%, p=0.017), fat (74% vs. 35%, p<0.001), saturated fat (89% vs. 65%, p<0.001), and sugar (60% vs. 30%, p<0.001) intake guidelines was also significantly higher among the disadvantaged women. Additionally, non-achievement of intake guidelines (EAR) for folate (35% vs. 21%, p=0.050), vitamin C (31% vs. 6%, p<0.001), vitamin D (80% vs. 67%, p=0.047) and calcium (25% vs. 10%, p=0.019) was higher among the disadvantaged women, while both groups showed poor compliance with iron and sodium intake guidelines. Higher smoking rates (p<0.001), higher alcohol consumption (p=0.029), lower participation in vigorous physical activity (p=0.001) and lower supplementation rates (p=0.004) were observed among the disadvantaged cohort, as were higher mean BMI (25.3 kg/m vs. 22.9 kg/m, p=0.001) and waist circumference measurements (87.9 cm vs. 79.7 cm, p<0.001). Quantitative analyses suggest that differences in attitudinal factors (dietary stage of change, locus of health control) predict some of these adverse behaviours, while deficits in diet and health knowledge and health information seeking may also contribute. The qualitative study additionally highlights the importance of psycho-social stress, depression, poor knowledge and cost as further impediments to healthy diet and lifestyle among disadvantaged women. These findings demonstrate the clustering of significantly less favourable diet, nutrient intakes and health behaviours among socially disadvantaged women in Dublin, trends which augur poorly for these women’s long-term health.
Low bit Rate Video Quality Analysis Using NRDPF-VQA Algorithm

In this work, we propose NRDPF-VQA (No Reference Distortion Patch Features Video Quality Assessment) model aims to use to measure the video quality assessment for H.264/AVC (Advanced Video Coding). The proposed method takes advantage of the contrast changes in the video quality by luminance changes. The proposed quality metric was tested by using LIVE video database. The experimental results show that the new index performance compared with the other NR-VQA models that require training on LIVE video databases, CSIQ video database, and VQEG HDTV video database. The values are compared with human score index analysis of DMOS.
Anatomical Study on the Descent of Testis in Prenatal Goat (Capra hircus)

Para observar el descenso de los testiculos se realizo un estudio en 70 embriones/fetos de cabra. Estos fetos se agruparon en 5 grupos: I (0-30 dias), II (31-60 dias), III (61-90 dias), IV (91 120 dias) y V (121 dias hasta termino, con 14 embriones / fetos en cada grupo. La cresta genital se observo a 1,2cm CRL (23 dias) en la cara ventromedial del mesonefros. En el dia 42 dia, la cresta genital se convirtio en estructura cilindrica y los testiculos se encontraban en el centro del metanefros. La migracion abdominal se completo en 88 dias. Los testiculos estan situados en el canal inguinal entre los 89 y 95 dias. Del dia 90 en adelante, se observo la migracion escrotal, sin embargo, el testiculo no llego a la base del escroto hasta el termino del desarrollo. Durante el descenso de los testiculos, a los 42 dias, un pliegue peritoneal (gubernaculum testis) separado del extremo caudal de la gonada, se extendio hacia el suelo-abdominal. En las etapas iniciales de la prenez la gonada era delgada, blanquecina, gelatinosa. En el dia 70 el testiculo fue envuelto por el proceso vaginal. En el grupo V, el testiculo se habia endurecido y alargado asemejandose a una cuerda.
Das virtuelle Bauwerk - Kombinierte skalenübergreifende Visualisierung von ZfPBau Ergebnissen

Kurzfassung. Die Zustandserfassung und Schadensdiagnose an Stahlund Spannbetonbauwerken mit zerstorungsfreien Prufverfahren im Bauwesen (ZfPBau) ist ein Bereich, in dem Informationen von verschiedenen Skalen fur die Gesamtbewertung eines Bauwerks zusammengefuhrt werden mussen. Entwicklungen, die dem/der sachkundigen Planer/in Werkzeuge an die Hand geben, mit deren Hilfe umfassende und nachhaltige Bewertungen vorgenommen werden konnen, gibt es bislang nur ansatzweise. Jedoch sind mittlerweile die technischen Moglichkeiten gegeben, diese mehrskaligen Information zu erfassen und virtuell zusammenzufuhren. Die Ansatze zur skalenubergreifenden Zusammenfuhrung von ZfPBau Daten wurden beispielhaft im Rahmen eines Forschungsvorhabens, gefordert durch das Ministerium fur Wirtschaft und Wissenschaft des Saarlandes, untersucht. Einige Ergebnisse aus diesem Vorhaben werden im folgenden als eine Moglichkeit vorgestellt, verschiedene Untersuchungen in einem virtuellen Bauwerk zusammenzufugen. Es werden exemplarisch einige Teilaspekte einer Bauwerksaufnahme vorgestellt. Dies beinhaltet die optische Gebaudeaufnahme durch Befliegung mittels Mikrokopter, die automatisierte Multi-Sensor Datenerfassung, die Einbindung neuer Auswerteansatze bei Multi-Sensor ZfPBau Anwendungen und die letztendliche Visualisierung von Prufergebnissen auf verschiedenen Skalen in einem virtuellen Bauwerksmodell.
Beïnvloeding van gedragsmotivatie in het verkeer

De verkeersveiligheid is een belangrijk onderdeel in de hedendaagse maatschappij. Er wordt continu gezocht naar manieren om het aantal verkeersongevallen te minimaliseren. Met behulp van psychologische modellen worden interventies bedacht en projecten gestart met oog op de verkeersveiligheid. Diverse theorieen geven aspecten aan die een rol spelen bij de keuze een bepaald gedrag wel of niet uit te voeren. In dit onderzoek wordt met behulp van fear appeal gekeken naar de betrokken determinanten bij de motivatie tot het vertonen van gewenst gedrag. Daarbij wordt in een online vragenlijst de subjectieve norm gemanipuleerd om te zien of dit facet een rol speelt ofwel een invloed heeft op andere aspecten. De resultaten laten geen significante relatie zien tussen het gemanipuleerde aspect en andere gemeten constructen. De leeftijd geeft wel een significante relatie met de mate waarin iemand denkt de situatie te controleren als deze actie uitgevoerd wordt en hoe iemand tegen het gedrag aankijkt. Daarnaast zijn er hoge onderlinge correlaties gevonden tussen de determinanten uit de gebruikte theorieen. Het onderzoek laat duidelijk zien dat de subjectieve norm geen verdere relaties vertoond in de desbetreffende psychologische modellen.
Mothers of Survivors of Childhood Cancer

Abstract Numerous studies have examined the psychosocial effects of childhood cancer on teenage and young adult survivors. Yet, there is relatively little research on the consequences of survivorship for the parents of these people. This study explored the realities of life for mothers of survivors of childhood cancer. Data from self-report questionnaires with 167 mothers of survivors and follow-up intensive interviews with 29 of them were analyzed. Findings indicated that mothers' worries were not so much a function of “objective” physical consequences of their child's illness. Instead, their worries were significantly related primarily to their own perceptions of their child's worries and the meanings they attached to their own and their child's cancer experience. The implications of the results for intervention with survivors of childhood cancer and their families include hospital-organized information and education programs; supportive counseling; meetings with other parents; and, for parents whose children have actual limitations, supportive rehabilitation services.
Fault Tolerant Sliding Mode Control Schemes With Aerospace Applications

FAULT TOLERANT SLIDING MODE CONTROL SCHEMES WITH AEROSPACE APPLICATIONS Halim Alwi The thesis concerns the theoretical development and implementation of sliding mode schemes for fault tolerant control. The theoretical ideas developed in the thesis have been applied to aerospace systems. In particular, actuator and sensor fault tolerant control schemes have been developed for a high fidelity full nonlinear model of a Boeing 747 aircraft which is a widely researched testbed in the open literature. A key development in this thesis considers sliding mode control allocation schemes for fault tolerant control based on integral action and a model reference framework. Unlike many control allocation schemes in the literature, one of the main contributions of this thesis is the use of actuator effectiveness levels to redistribute the control signals to the remaining healthy actuators when faults/failures occur. A rigorous stability analysis and design procedure is developed from a theoretical perspective for this scheme. A fixed control allocation structure is also rigorously analyzed in the situation when information on actuator effectiveness level is not available. The proposed scheme shows that faults and even certain total actuator failures can be handled directly without reconfiguring the controller. A design of an adaptive gain for the nonlinear component of the sliding mode controller for handling faults is also described. The later chapters of the thesis present the results obtained from real time hardware implementations of the controllers on the 6-DOF SIMONA flight simulator at Delft University of Technology as part of the GARTEUR AG16 programme. The schemes have been evaluated by experienced pilots and the results have shown good performance in both nominal and failure scenarios. A reconstruction of the Bijlmermeer ELAL 1862 scenario on SIMONA using one of the controllers shows that a safe flight and landing is possible with significant reduction in pilot workload when compared with the classical controller.
A regulator design to address actuator failures

When an actuator fails and jams, it not only reduces the control authority but also presents a persistent disturbance to the system. In this paper we propose a regulator design to address the actuator failure. A set of regulator controllers are designed for all possible actuator failures and a switching mechanism determines which controller to step in to address the specific actuator failure. The mechanism needs to detect the dysfunctional actuators; however, the actuator's jam position is not necessarily known. The controller has the capability of regulating against all persistent disturbances with unknown magnitude. An automatic carrier landing system with jammed control surfaces is employed to illustrate the proposed design strategy.
Chinese Dialogue Intention Classification Based on Multi-Model Ensemble

In dialogue systems, understanding the user utterances is crucial for providing appropriate responses. A traditional dialogue act classification (DA) task is to classify each user reply into “ACCEPT, REJECT, PROPOSE, and others”. In contrast, in this paper, we define the DA task on multiple round conversations between humans. The re-defined task is to classify a full dialogue according to the intention of one participant. We term this task as intention classification (IC). We, then, propose a hybrid neural network-based ensemble model for solving this problem. Two novel ensemble schemes are introduced for combining the classification results or features from various classifiers. One is ensembling features from each individual classifier using stacking, and we term this scheme as SFE. The other is adding wrong examples’ weight to loss functions of each individual classifier using the AdaBoost scheme, and we term this scheme as MN-Ada. We have empirically examined the performance of the proposed ensemble schemes by using three popular deep neural networks, as well as one newly modified networks for IC. Extensive experiments have been conducted on a Chinese dialogue corpus. Our model can achieve state-of-the-art accuracy on the experimental dialogue corpus.

Issues Affecting HIV-Positive Women Who Attend Community Care Centers in Kerala, India: Practitioners’ Accounts of Stigma

This research identifies the psychosocial needs of HIV-positive women attending two of the newly established Community Care Centres in Kerala, as recounted by the health care practitioners of those services. Findings include the complex and devastating impacts of the stigma associated with HIV/AIDS on women's lives, including their avoidance of health care due to fear of disclosure and the denial of their children's access to education. The report suggests that further research into the linkages between the different stakeholders, to fully exploit the successful strategies employed by each to combat the stigma, may well be beneficial in addressing one of the most damaging and pervasive challenges of the disease.
Robot Learning from Demonstration Using 3D Computer Vision

For robot application to proliferate in industry, and in unregulated environments, a simple means of programming is required. This paper describes methods for robot Learning from Demonstration (LfD). These methods used an RGB-D sensor for demonstration observation, and used finite state machines (FSMs) for policy derivation. Particularly, a method for object recognition was developed, which required only a single frame of data for training, and was able to perform real-time recognition. A planning method for object grasping was also developed. Experiments with a pick-and-place robot show that the developed methods resulted in object recognition accuracy greater than 99% in cluttered scenes, and manipulation accuracies of below 3mm in linear motion and 2° in rotation.
Multiview‐coherent disocclusion synthesis using connected regions optimization

Handling of missing areas is a key step for depth‐based rendering to synthesize virtual views. Existing methods usually consider finding candidate pixels from only one reference view to fill missing areas. However, the information provided by one reference view is restricted by the position of the view. By utilizing two reference views located on both the left and right sides of the virtual view, we propose to synthesize the missing areas at hole level with connected regions optimization. To avoid the appearance of ghost boundary, we apply morphological operations to generate a boundary band map for the depth map, which restricts the warping of the virtual view. We use a binary map to mark unknown pixels in a hole, label the connected unknown regions, and count the area of each connected region, which decide the order in our enhanced inpainting synthesis. Besides, we separate the foreground and background regions of the depth map to constrain the searching of candidate pixels. Multiple experiments on virtual view synthesis have shown the effectiveness and high quality of our multiview‐coherent disocclusion synthesis.
Are educational preschool apps designed to teach? An analysis of the app market

ABSTRACT Over half of educational apps on mobile-app markets are for preschoolers, but little research has examined whether the designs of preschool apps are truly educational. Preschoolers process information differently from older learners (i.e., shorter attention spans), so app designs should be guided by developmental science. This content analysis of popular Apple and Android math and literacy preschool apps uses a developmental framework to code and analyze apps’ educational features. Findings show a wide variety of features apps used. However, few provided developmentally appropriate guidance, like scaffolded feedback. This study offers insights for improving apps to meaningfully teach preschoolers.
RF-RPC: Remote Fetching RPC Paradigm for RDMA-Enabled Network

Remote Direct Memory Access (RDMA) devices are widely deployed in modern data centers. However, existing RDMA usages lead to a dilemma between performance and redesign cost. Server-reply mode directly replaces socket-based send/receive primitives with corresponding RDMA counterparts. It can not fully harness the power of RDMA devices. Server-bypass is distinct mode provided by RDMA for reaching the hardware limits. This mode can totally bypass the server by using one-sided RDMA operations but at the cost of redesigning software. This paper provides a different approach, called RF-RPC (Remote Fetching RPC Paradigm). Different from server-reply, RF-RPC makes client fetch the results from server using one-sided RDMA instead of waiting the results pushed by server. Different from server-bypass, RF-RPC demands server to process client's requests for supporting programming paradigm like RPC. Thus, RF-RPC can achieve high performance without abandoning traditional programming models. An RF-RPC supported in-memory key-value store shows that the performance can be improved by 1.6× comparing to server-reply paradigm and 4× comparing to server-bypass paradigm.
