Representation of the Cattell Horn Carroll Theory of Cognitive Abilities in the Factor Structure of the Dutch Language Version of the WAIS IV
Venue: Assessment
Year: 2017

The Cattell Horn Carroll (CHC) theory of cognitive abilities has been guiding in the revision of the Wechsler Adult Intelligence Scale Fourth edition (WAIS IV) Especially the measurement of fluid reasoning (Gf) is improved. A total of five CHC abilities are included in the WAIS IV subtests. Using confirmatory factor analysis, a five factor model based on these CHC abilities is evaluated and compared with the four index scores in the Dutch language version of the WAIS IV. Both models demonstrate moderate fit, preference is given to the five factor CHC model both on statistical and theoretical grounds. Evaluation of the WAIS IV according to CHC terminology enhances uniformity, and can be important when interpreting possible sources of index discrepancies. To optimally assemblage CHC and WAIS IV, more knowledge of the interaction of abilities is needed. This can be done by incorporating intelligence testing in neuropsychological assessment. Using this functional approach contributes to a better understanding of an individual's cognitive profile.
Quality grading system of Jadeite Jade green based on three colorimetric parameters under CIE standard light sources D 65 CWF and
Year: 2017

The article deals with the color changes appearing under different light sources due to the individual and combined effects of lightness, hue and chroma. As a result, a green color grading system is created based on color evaluation from its appearance. We tested the color of 277 pieces of green jadeite specimens using Color i5 spectrophotometer based on CIE 1976 L*a*b* uniform color space and Munsell color matching system. It was concluded that the CIE standard light source D65 is more suitable for assessing jadeite jade green compared with the CIE standard light sources CWF and A. After the alternate use of light sources D65 and A, the color shows a slight yellow tone. While the light source changed from D65 to CWF, the lightness of jadeite jade green decreased sharply. The jadeite jade green concentrates on the lightness scope of (5.64, 61.96) and most of them focus on the scope of moderate to brighter lightness of (30, 60) It is shown that the optimal green of jadeite jade is deep and dark. The support vector machine (SVM) predicts that 20 of 35 unclassified jadeite jade cabochons should have a corresponding level based on the color green grading system of jadeite jade. Taking into account the combination of theory and practice, the conclusion is drawn that the color green grading system of jadeite jade should be calculated in the CIE 1976 L*a*b* uniform color space combined with the Munsell color system for physical color comparison.
Las tecnologias de la informacion y comunicacion como recurso didactico para la adquisicion y desarrollo de la competencia digital en alumnos de educacion secundaria estudio de casos
Year: 2017

El Decreto 86/2015, de 25 de junio, por el que se establece el curriculo de Educacion Secundaria Obligatoria y de bachillerato en la Comunidad Autonoma de Galicia, establece siete competencias clave que en el futuro, los alumnos necesitaran para su realizacion y desarrollo personal, para su inclusion social, su empleabilidad y para formar parte de una ciudadania cada vez mas activa y participativa. En el presente trabajo, se muestran los resultados de una investigacion desarrollada en centros de Educacion Secundaria de la comunidad autonoma gallega, pertenecientes a la red del Programa Abalar. En ella, su proposito es analizar el proceso de integracion de las Tecnologias de la Informacion y Comunicacion en las practicas de ensenanza y aprendizaje, en alumnos de Educacion Secundaria y en que medida contribuyen a la adquisicion de la competencia digital (CD) en esta etapa, tan importante e intrinsecamente ligada al resto de competencias clave, en este nuevo ecosistema digital. Se ha realizado una investigacion de tres anos basada en el estudio de casos siguiendo el caso tipico (Merrian, 1998) seleccionando a 4 profesores de centros educativos pertenecientes a la red del programa Abalar, de la Conselleria de Educacion e Ordenacion Universitaria de la Xunta de Galicia. Para la recoleccion de datos se han realizado: entrevistas en profundidad, observaciones, grupos de discusion, analisis de documentos del centro y de los artefactos. Despues del analisis de los datos obtenidos, observamos los cambios positivos que se manifiestan en el centro a nivel organizativo, despues de la llegada de la tecnologia. No se produce un cambio metodologico determinante en la practica docente diaria en las materias analizadas. El alumnado aun se encuentra en un estadio inicial en la adquisicion de la CD, despues del analisis de las distintas dimensiones. Destacamos de forma positiva en primera instancia que, este proyecto ha permitido que muchos centros integren el uso de TIC en la practica educativa, provocando cambios en su forma tradicional de plantear el proceso de ensenanza/aprendizaje. No obstante, no se observa todavia el cambio metodologico significativo y deseable, corroborando otros estudios que indican que aun son un recurso infrautilizado en los centros educativos (Sigales y Momino, 2004) La necesidad de formacion del profesorado y las dificultades de distinta naturaleza, que ellos encuentran para aplicar en su dia a dia cualquier innovacion, orientan a la creacion en el futuro de itinerarios formativos del profesorado. Se destaca la importancia en el futuro de una persona dinamizadora TIC en el centro y la conveniencia de perfiles directivos especificos en la aplicacion de las politicas a las practicas educativas.
An Underwater Robot Positioning Method Based on EM ELF Signals
Venue: ICIRA
Year: 2019

In view of the limited positioning of underwater robots using GPS and high frequency radio waves, extremely low frequency electromagnetic (EM ELF) signals are effective ways to solve the positioning accuracy of underwater robots due to their strong penetrating power, low loss and low interference. Based on the localization method, first proposed by Sheinker et al.  and combined with the excellent characteristics of firefly algorithm, this paper proposes an underwater robot positioning method based on ultra low frequency electromagnetic signals. The method in this paper has the following advantages: (1) It compensates for the problem that the accuracy is reduced in a short time when the electromagnetic signal is used for positioning, and the robustness of the positioning is improved; (2) Under the condition of not using the geophysical reference map, it can realize the autonomous positioning of the underwater robot all day, and improve the accuracy of the positioning system; (3) It has strong anti interference ability and is suitable for underwater robot navigation under weak illumination and time varying interference environment. The experimental results also show that the method has small positioning error and can accurately locate the underwater robot.
Angular momentum transfer in primordial discs and the rotation of the first stars
Year: 2018

We investigate the rotation velocity of the first stars by modelling the angular momentum transfer in the primordial accretion disc.Assessing the impact of magnetic braking, we consider the transition in angular momentum transport mode at the Alfv$\acute{\rm e}$n radius, from the dynamically dominated free fall accretion to the magnetically dominated solid body one.The accreting protostar at the centre of the primordial star forming cloud rotates with close to breakup speed in the case without magnetic fields.Considering a physically motivated model for small scale turbulent dynamo amplification, we find that stellar rotation speed quickly declines if a large fraction of the initial turbulent energy is converted to magnetic energy \gtrsim 0.14$ Alternatively, if the dynamo process were inefficient, for amplification due to flux freezing, stars would become slow rotators if the pre galactic magnetic field strength is above a critical value, \simeq 10^ 8.2}$G, evaluated at a scale of $n_{\rm H} 1 \rm cm} 3} which is significantly higher than plausible cosmological seed values \sim 10^ 15}$G) Because of the rapid decline of the stellar rotational speed over a narrow range in model parameters, the first stars encounter a bimodal fate: rapid rotation at almost the breakup level, or the near absence of any rotation.
Functional amino acids in nutrition and health
Venue: Amino Acids
Year: 2013

The recent years have witnessed growing interest in biochemistry, physiology and nutrition of amino acids (AA) in growth, health and disease of humans and other animals. This results from the discoveries of AA in cell signaling involving protein kinases, G protein coupled receptors, and gaseous molecules (i.e. NO, CO and H2S) In addition, nutritional studies have shown that dietary supplementation with several AA (e.g. arginine, glutamine, glutamate, leucine, and proline) modulates gene expression, enhances growth of the small intestine and skeletal muscle, or reduces excessive body fat. These seminal findings led to the new concept of functional AA, which are defined as those AA that participate in and regulate key metabolic pathways to improve health, survival, growth, development, lactation, and reproduction of the organisms. Functional AA hold great promise in prevention and treatment of metabolic diseases (e.g. obesity, diabetes, and cardiovascular disorders) intrauterine growth restriction, infertility, intestinal and neurological dysfunction, and infectious disease (including viral infections)
von Willebrand factor Jedi knight of the bloodstream
Year: 2014

When blood vessels are cut, the forces in the bloodstream increase and change character. The dark side of these forces causes hemorrhage and death. However, von Willebrand factor (VWF) with help from our circulatory system and platelets, harnesses the same forces to form a hemostatic plug. Force and VWF function are so closely intertwined that, like members of the Jedi Order in the movie Star Wars who learn to use "the Force" to do good, VWF may be considered the Jedi knight of the bloodstream. The long length of VWF enables responsiveness to flow. The shape of VWF is predicted to alter from irregularly coiled to extended threadlike in the transition from shear to elongational flow at sites of hemostasis and thrombosis. Elongational forcepropagated through the length of VWF in its thread like shape exposes its monomers for multimeric binding to platelets and subendothelium and likely also increases affinity of the A1 domain for platelets. Specialized domains concatenate and compact VWF duringbiosynthesis.A2domainunfolding by hydrodynamic force enables postsecretion regulationofVWFlength.Mutations in VWF in vonWillebrand disease contribute to and are illuminatedbyVWFbiology. I attempt to integrate classic studies on the physiology of hemostatic plug formation intomodernmolecularunderstanding, and point out what remains to be learned.
SURF: Speeded Up Robust Features
Year: 2009

In this document, the SURF detector descriptor scheme used in the OpenSURF library is discussed in detail. First the algorithm is analysed from a theoretical standpoint to provide a detailed overview of how and why it works. Next the design and development choices for the implementation of the library are discussed and justified. During the implementation of the library, it was found that some of the finer details of the algorithm had been omitted or overlooked, so Section 1.5 serves to make clear the concepts which are not explicitly defined in the SURF paper
Visible light induced photocatalytic mitigation of ibuprofen using magnetic black TiO2 x/CaFe2O4 decorated on diatomaceous earth.
Venue: The Science of the total environment
Year: 2020

This study reports a facile preparation of black TiO2 x/CaFe2O4 (Ti3+ self doped titania coupled with calcium ferrite) an efficient photocatalyst for ibuprofen (IBP) oxidation under visible light irradiation. Compared with TiO2 x or CaFe2O4, TiO2 x/CaFe2O4 heterojunction displayed better photo oxidation performance, and their immobilization onto diatomaceous earth (DE) further increased the oxidation rate due to the adsorption ability of DE. The morphology, phase composition and other physicochemical properties of the composite were studied using different characterization methods. The effects of several parameters on IBP oxidation efficiency were studied, such as pH, IBP concentration, catalyst dosage, co existing ions, microplastics and peroxymonosulfate (PMS) Quenching experiment results demonstrated the roles of the following reactive species: hydroxyl radical, photo induced hole, sulfate radical and superoxide radical. The intermediates during IBP oxidation were determined by HPLC MS method, and their acute toxicity was studied. Furthermore, the plausible reaction pathway and mechanism were proposed.
15 Keypoints Is All You Need
Venue: 2020 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)
Year: 2020

Pose tracking is an important problem that requires identifying unique human pose instances and matching them temporally across different frames in a video. However, existing pose tracking methods are unable to accurately model temporal relationships and require significant computation, often computing the tracks offline. We present an efficient multi person pose tracking method, KeyTrack that only relies on keypoint information without using any RGB or optical flow to locate and track human keypoints in real time. KeyTrack is a top down approach that learns spatio temporal pose relationships by modeling the multi person pose tracking problem as a novel Pose Entailment task using a Transformer based architecture. Furthermore, KeyTrack uses a novel, parameter free, keypoint refinement technique that improves the keypoint estimates used by the Transformers. We achieve state of the art results on PoseTrack'17 and PoseTrack'18 benchmarks while using only a fraction of the computation used by most other methods for computing the tracking information.
User centered development of a smart phone mobile application delivering personalized real time advice on sun protection
Venue: Translational behavioral medicine
Year: 2013

ABSTRACTSmart phones are changing health communication for Americans. User centered production of a mobile application for sun protection is reported. Focus groups (n 16 adults) provided input on the mobile application concept. Four rounds of usability testing were conducted with 22 adults to develop the interface. An iterative programming procedure moved from a specification document to the final mobile application, named Solar Cell. Adults desired a variety of sun protection advice, identified few barriers to use and were willing to input personal data. The Solar Cell prototype was improved from round 1 (seven of 12 tasks completed) to round 2 (11 of 12 task completed) of usability testing and was interoperable across handsets and networks. The fully produced version was revised during testing. Adults rated Solar Cell as highly user friendly (mean 5.06) The user centered process produced a mobile application that should help many adults manage sun safety.
Coronary angiography in out of hospital cardiac arrest without ST elevation on ECG Short and long term survival
Venue: American heart journal
Year: 2018

The potential benefit of early coronary angiography in out of hospital cardiac arrest (OHCA) patients without ST elevation on ECG is unclear. The aim of this study was to evaluate the association between early coronary angiography and survival in these patients.  Nationwide observational study between 2008 and 2013. Included were patients admitted to hospital after witnessed OHCA, with shockable rhythm, age 18 to 80 years and unconscious. Patients with ST elevation on ECG were excluded. Patients that underwent early CAG (within 24 hours) were compared with no early CAG (later during the hospital stay or not at all) Outcomes were survival at 30 days, 1 year, and 3 years. Multivariate analysis included pre hospital factors, comorbidity and ECG findings.  In total, 799 OHCA patients fulfilled the inclusion criteria, of which 275 (34% received early CAG versus 524 (66% with no early CAG. In the early CAG group, the proportion of patients with an occluded coronary artery was 27% and 70% had at least one significant coronary stenosis (defined as narrowing of coronary lumen diameter of =50% The 30 day survival rate was 65% in early CAG group versus 52% with no early CAG (P .001) The adjusted OR was 1.42 (95% CI 1.00 2.02) The one year survival rate was 62% in the early CAG group versus 48% in the no early CAG group with the adjusted hazard ratio of 1.35 (95% CI 1.04 1.77)  In this population of bystander witnessed cases of out of hospital cardiac arrest with shockable rhythm and ECG without ST elevation, early coronary angiography may be associated with improved short and long term survival.
On Assessing the Political Effects of Racial Prejudice
Year: 2009

There is still no broad consensus on the extent to which racial prejudice influences white Americans' political attitudes, in part because of an ongoing dispute over the nature and measurement of racial prejudice. We review measures of new, subtle forms of racism toward African Americans and consider criticism that such views do not clearly constitute racial prejudice despite their political impact. We then evaluate a number of ways in which explicit prejudice can be assessed in surveys, highlighting the continued existence and successful measurement of overt prejudice. We also consider ways to measure prejudice other than direct survey questions. Social psychologists have gravitated to the measurement of implicit racial attitudes, an approach that we review critically as potentially interesting but with unknown payoff for political researchers. Finally, we discuss the value of experiments as a way to gain direct evidence of politically potent racial discrimination and assess the prejudicial nature of exp.
Studying the Relations between Emotional Intelligence and Occupational Stress A Case Study at Payame
Year: 2011

The purpose of this study was to explore and describe the relationship between emotional intelligence and occupational stress and its influence on the center of Payame Noor University organization. To this aim, a sample of 134 from among 900 employees working in PNU center organization was selected by simple sampling. Two Questionnaires were used in the study: The Swinburne University Emotional intelligence Test (SUEIT) and the Occupational Roles Questionnaire (ORQ) .Data obtained from this study were analyzed using Pearson correlation and multiple regression. In order to study the relationship between emotional intelligence and occupational stress, path analysis technique has been used. The results show that there is an inverse significant relationship between occupational stress and emotional intelligence that significantly correlated with job performance. There is a significant relationship between subscales of emotional intelligence and emotional stress, indicating that most affection is related to emotional management subscale (b 0.4, p<0.05) the most important subscale of emotional intelligence is related to understanding other emotions (kh2 3.63, a 0.05) the most important subscale of occupational stress is related to role overload (kh2 4.16, a=0.05) The conceptual model of research has a good fit and confirms the hypotheses regarding the relationship between emotional intelligence and occupational stress (kh2=18.20, DF=43, pValue=0.36721, RMSEA 0.013) Moreover, results show that if custodians take emotional intelligence into account in suitable ways, it can play an effective role in reducing occupational stress.
Robust Adaptive Sliding Mode Control of Nonlinear Systems Using Neural Network
Venue: 2020 17th International Multi Conference on Systems, Signals Devices (SSD)
Year: 2020

Many higher order complex nonlinear systems with unknown parameters cannot be expressed in the so called linear in the unknown parameters form. This brings a huge obstacle to the application of adaptive control to estimate the unknown parameters. Instead of estimating each of the unknown parameters of a function, a feed forward neural network (NN) can approximate the whole function due to its universal approximation property. In this study, an adaptive neural network integral fast terminal sliding mode controller (NN IFTSMC) has been proposed for a general n th order nonlinear systems with parametric uncertainties and external disturbances. The closed loop system has been proven to be bounded near the origin using Lyapunov criterion. The designed control scheme was applied to a quadrotor (UAV) and an excellent trajectories' tracking were obtained.
Discriminative out of distribution detection for semantic segmentation
Venue: ArXiv
Year: 2018

Most classification and segmentation datasets assume a closed world scenario in which predictions are expressed as distribution over a predetermined set of visual classes. However, such assumption implies unavoidable and often unnoticeable failures in presence of out of distribution (OOD) input. These failures are bound to happen in most real life applications since current visual ontologies are far from being comprehensive. We propose to address this issue by discriminative detection of OOD pixels in input data. Different from recent approaches, we avoid to bring any decisions by only observing the training dataset of the primary model trained to solve the desired computer vision task. Instead, we train a dedicated OOD model which discriminates the primary training set from a much larger "background" dataset which approximates the variety of the visual world. We perform our experiments on high resolution natural images in a dense prediction setup. We use several road driving datasets as our training distribution, while we approximate the background distribution with the ILSVRC dataset. We evaluate our approach on WildDash test, which is currently the only public test dataset that includes out of distribution images. The obtained results show that the proposed approach succeeds to identify out of distribution pixels while outperforming previous work by a wide margin.
Research on Collaborative Product Design Issue Tracking Management Model
Year: 2012

Product development teams are usually confronted with numerous issues in collaborative design process. The issue tracking management can provide the efficiency and effectiveness of the development process. Firstly, the process of issue tracking management and organization are analyzed. We study the relationship between privileges of role's and issue states. Secondly, we propose a product issues structure model (PISM) which associates issues with product at the component level. With the PISM, the developers can understand of the issue state so as to promote the issue resolution. Finally, we applied an approach which analyzes the density of product issues in the evolvement of product issue structure to assist the product manager in identifying improvement opportunities
