Fast Aerial UAV Detection Based on Image Segmentation and HOG-FLD Feature Fusion

Abstract In order to detect non-cooperative target UAV quickly and accurately, a novel method of UAV detection method based on graph theory and HOG-FLD feature fusion is presented in this paper. In order to avoid the time-consuming full search, the candidate areas of the UAV are obtained through the selective search of the image segmentation and the similarity, and the features are extracted through the method of gradient orientation histogram fusion FLD linear to train the SVM classifier with generalization ability to identify the UAV. The method can detect the UAV quickly and accurately under complicated background and circumstances of various position and angle. Compared with the sliding window method based on image segmentation and HOG+SVM, the experimental results show that the speed of this method has been obviously improved with the same recognition accuracy.
Teaching Creative Abilities of Children in Music Education in the General School

In a community, where the consumer's attitude in all aspects of life is ever more commonly observed, including in the area of culture, the problem of stimulating the creative impulse, of training the creative activity of adolescents, becomes especially important. Responsible for seeking the appropriate means and methods for the development of the creative abilities in children are the parents, tutors, teachers. An important role, in that relation, could be entrusted to the music teacher in the general school.
Factorial Invariance of Academic Self-Efficacy Scale in Men and Women University Students

The present study analyses the psychometric properties of the Self-efficacy in Academic Behaviors Scale in men and women university students. The overall sample consisted of 2006 subjects: 902 women and 1104 men, with a mean age of 18.53 years (SD= 1.52) and 18.84 years (SD= 1.55) respectively. Psychometric analysis showed that a three-factorial structure (Communication, Attention and Excellence) was viable and adequate for both populations (men and woman) according to the established psychometric requirements when the informers are the students themselves. In addition, the factor structure, factorial loads and intercepts are considered invariant in the two populations; however, there are differences between groups in favor of women for the means of the three factors.

QUICK ESTIMATION OF TSUNAMI INDUCED RUNUP ON COASTAL AREA

The main purpose of this study is that extending 1D Carrier-Wu-Yeh algorithm and analytical Green’s function (AGF) to estimate the arbitrary irregular waveforms induced runup height and the inundation distance, and further builds a pre-calculated runup dataset. In this study, the multiplication and superposition is employed to replace the direct numerical integration. The waveforms are decomposed as numerous Fourier components using fast Fourier transformation. The corresponding mechanical energy can be calculated beforehand and save the results as a database-form. Using this process, the maximum runup height and the inundation distance can be quick calculated after determining the total mechanical energy. Based on application on the real tsunami events, the comparisons show that the present methodology can shorten the computing time in comparison with the direct numerical integration. Moreover, the present approach also applies on real tsunami events, 2004 Indian tsunami and 2011 Tohoku tsunami, to estimate the runup height and the inundation distance. The forecasted results are quite satisfactory in comparison with the field measurement, and it implies that the reasonable accuracy and the computing efficiency are both considered in this study.
Improving Location Prediction by Exploring Spatial-Temporal-Social Ties

As there is great differences of movement patterns and social correlation between weekdays and weekends, we propose a fallback social-temporal-hierarchic Markov model (FSTHM) to predict individual’s future location. The division of weekdays and weekends is used to decompose the original state of traditional Markov model into two different states and distinguish the difference of the strength of social ties on weekdays and weekends. Except for the time division, the distribution of the visit time for each state is also considered to improve the predictive performance. In addition, in order to best suit the characteristics of Markov model, we introduce the modified cross-sample entropy to quantify the similarities between the individual and his friends. The experiments based on real location-based social network show the FSTHM model gives a 9% improvement over the Markov model and 2% improvement over the social Markov models which use cosine similarity or mutual information to measure the social correlation.
Planning with the Center-of-Mass rather than Stances for Humanoids Walking on Uneven Terrains

In the current literature for non-gaited hu- manoid motion planning, stances (i.e., contact locations) are usually planned in a first step, after which joint-angle trajectories are interpolated or planned themselves. In this paper, we propose an alternative where planning is driven by center-of-mass motions rather than stances. Our approach uses a randomized motion planner as its first layer to explore the space of horizontal CoM coordinates (xG;yG). At a lower level, we propose a custom method to e xtend stances based on a desired CoM position. We evalu- ate the ability of the resulting planner in a rubble-field 3D environment with a model of the HYDRA humanoid robot.

Cloning and expression analysis of two photosynthetic genes , PSI-H and LHCB 1 , under trehalose feeding conditions in Arabidipsis seedlings

Trehalose (α-D-glucosyl-[1,1]-α-D-glucopyranoside) is involved in mechanisms that coordinate metabolism with plant growth adaptation and development. The main objective of the current work was to find out whether trehalose feeding affects the expression of two genes involved in photosynthesis: one gene coding for photosystem1 subunit H (PS1-H) and the other for the light harvesting complex B1 (LHCB1). In this study, Arabidopsis seeds were grown on one-halfstrength medium supplemented with 100 mM trehalose or sorbitol (as osmotic control) for 2 weeks. Trehalose-fed seedlings showed inhibited root growth, delayed emergence of primary cotyledons and darkrimmed cotyledons. Exogenously applied trehalose strongly induced starch accumulation in cotyledons and, concomitantly, depletion of starch in collumella cells of the root cap. Gene expression analysis of photosynthetic genes in Arabidopsis seedlings revealed that trehalose feeding repressed PS1-H and LHCB1 expression as compared to sorbitol-fed seedlings. To confirm trehalose inhibitory effect on photosynthetic gene expression, the cDNA of PS1-H and LHCB1 was used to transform Arabidopsis seedlings. Transformed lines showed higher transcript levels of PS1-H and LHCB1.Trehalose feeding also reduced expression levels of PS1-H and LHCB1 in transformed lines. These findings show that trehalose down-regulates the expression of two genes encoding typical components of the photosynthetic machinery.
Comparative assessment of extreme climate variability and human activities on regional hydrologic droughts in the Weihe River basin, North China

Abstract. Drought is a comprehensive phenomenon not only resulting from precipitation deficits and climatic factors, but also being related to terrestrial hydrologic conditions and human activities. This paper investigated the relationships among regional hydrologic drought, climate extremes and human activities in the Weihe River basin, northwest China, where is also called Guanzhong Plain. First, the study period was divided into baseline and variation period according to the runoff trend analysis. Subsequently, the variable infiltration capacity (VIC) macroscale distributed hydrologic model was applied to reconstruct the natural runoff series in variation period. Furthermore, the effects of climate change and human activities on runoff were separated by the modelling results. Finally, standardized runoff index (SRI) and extreme climate indices were generated to quantatively assess the relationships among hydrologic droughts, climate extremes and human activity impacts. The results indicated that human activity impacts is a remarkable source of runoff reduction and represented an in-phase pattern of SRI-based drought severity and warm days. It also showed that the SRI-based floods and droughts characteristics are in good correlation with extreme precipitation.
3Rs missing: animal research without scientific value is unethical

The current, widely established 3R framework for the ethical use of animals in research consists of three guiding principles, that is, Replacement, Reduction and Refinement, all aiming to safeguard the overarching ethical principle of animal welfare. However, animal welfare alone does not suffice to make animal research ethical if the research does not have sufficient scientific value. The scientific value of animal studies strongly decreases if they are not sufficiently robust, if their questions have already been sufficiently addressed or if the results are selectively reported. Against this background, we argue that three guiding principles are missing, that is, Robustness, Registration and Reporting, all of which aim to safeguard and increase the scientific value of animal research. To establish a new 6R framework, we need a multistakeholder discourse to conceptualise the specific requirements of robustness, registration and reporting and to clarify responsibilities, competencies and legislation for auditing 6R compliance.
Acoustic behaviour of citric acid in aqueous and partial aqueous media

c Measurement of ultrasonic velocity, density and viscosity at different concentrations of citric acid in water, dimethylformamide, dimethylsulphoxide, and their mixtures have been carried out at 303 K using ultrasonic interferometer at frequency 2 MHz. The data obtained are used to evaluate various acoustic parameters in view of identification of the presence of ion-solvent interaction under prevailing conditions. Ultrasonic velocity has been found to increase with increase in the composition of DMSO and to decrease with DMF in water. The compressibility has been found to decrease with the increase in concentration for all compositions indicating the increase in ion-solvent interaction. mol dm -3) in water, DMF, DMSO and different compositions (v/v) of water + DMF and water + DMSO were prepared. Triply distilled water was used throughout the experiment. Non-aqueous solvents DMF and DMSO were purified as proposed earlier 11 . The ultrasonic velocity was measured using ultrasonic interferometer (M-81, Mittal enterprises, New Delhi) at a frequency of 2 MHz. The frequency was measured with an accuracy of 0.03%. The accuracy of the instrument was checked by comparing the experimental sound velocity of triply distilled water (1494 ms -1 ) with the theoretical sound velocity 12 (1496 ms -1 ) at 298 K. The velocity measurements were carried out for six solutions of citric acid of different concentrations (0, 0.05, 0.1, 0.2, 0.3, 0.4 and 0.5 mol dm -3 ) in water, DMF, DMSO and their mixtures (v/v), (0, 10, 20, 40, 60, 80 and 100%). The experiment was repeated at least twice and the average value is reported. Density and viscosity of all the solutions were determined using pyknometer of 10 cc capacity and Ostwalds viscometer, respectively at a known temperature.
Discontinuous Galerkin methods with solenoidal elements for the Stokes problem

The essential difficulty in the numerical solution of the incompressible Navier-Stokes (NS) equations is the coupling between the pressure and the velocity. The coupling enforces a constraint on the relation between the pressure and the velocity space. This constraint can be studied using a simplified form of the NS equations, viz. the Stokes equations. The present work examines the applicability of discontinuous Galerkin (DG) methods to the Stokes equations. Moreover, the application of DG-methods with locally solenoidal velocity fields is investigated. One of the main advantages of using DG-methods is their suitability to hp-adaptivity, as they can easily handle complex geometries and approximations that have polynomials of different degrees in different elements. We have restricted ourselves to the two most prominent DG methods for the Laplace operator, viz. the asymmetric Baumann-Oden (BO) method and the Symmetric Interior Penalty Galerkin (SIPG) method. This work presents stability analysis for various elements with diverse finite-element spaces, together with analytically and numerically determined error convergence rates. Also a measure for the computational effort is given for each element. Emphasis is put on varying combinations of polynomial orders for the velocity and pressure spaces, showing the possibilities for adaptivity. Using the results of these tests, we see that applicability of DG-methods for the Stokes problem is very promising, especially with respect to stability, implementation of non-homogeneous boundary conditions and adaptivity. Taking into account the error convergence, computational cost and the adaptivity properties, the solenoidal DG-element with discontinuous pressure on the skeleton is the most promising element. For this element the SIPG-method is the best method, because it is more stable and convergence is somewhat better than the BO-method, unless a penalty parameter is undesirable. In that case one should opt for the BO-method.

Annuity Markets in Chile: Competition, Regulation - and Myopia?

The author studies annuity rates in Chile and relates them with industry competition. He finds (1) that annuity insurance companies paying higher broker commissions paid lower annuity rates; and (2) a structural break of the long-run elasticity of annuity rates to the risk-free rate in 2001. Moreover, this structural break coincided with the submission of a new draft pension law proposing greater transparency in annuity markets and a generalized drop in broker commissions. The high commissions charged in the 1990s were partly returned to annuitants as informal (and illegal) cash rebates. Myopic pensioners preferred cash rebates over present values. Thus, the legal threat caused the drop in broker commissions, reduced the illegal practice of cash rebates, increased competition by way of annuity rates, and raised the long-run elasticity to one.

The prevalence of urinary incontinence in elderly Canadians and its association with dementia, ambulatory function, and institutionalization

Study objectives: Design and setting: Main results: Conclusion: Key words: urinary incontinence; dementia; institutionalization; community-institutional relations Urinary incontinence is a prevalent condition among the elderly, and is associated with age, dementia, and ambulatory function. Although incontinence is highly prevalent among institutionalized persons, the majority of persons with incontinence live in the community. Overall, 16.9% of the women and 8.0% of the men reported incontinence, the numbers for daily incontinence were 7.0% and 5.2% respectively. The prevalence increased by age, severity of dementia, and decreasing ambulatory function. It is calculated that 69% of elderly men and 73% of elderly women with any incontinence live in the community. 31% of the male and 32% of the female patients have some kind or severity of dementia, and 21% of the men and 27% of the women have decreased ambulatory function. One half of the persons with incontinence live in the community, with no cognitive or ambulatory impairment. Population based multi-centre survey with stratified random sampling all over Canada. Randomly selected persons aged 65 and over were interviewed. Those having cognitive impairment (n=1614), a randomly selected sample of those without (n=731) and an institutional sample (n=1255) underwent clinical assessment. Data from The Canadian Study of Health and Aging are analysed for prevalence of urinary incontinence, and its association with dementia, ambulatory function, and institutionalization. ABSTRACT
The Role of Participatory Workshops in Investigating Narrative and Sound Ecologies in the Design of an Ambient Intelligence Audio Display

We describe two participatory workshops conducted to support design decisions in the making of the audio display for an ambient intelligent game platform. The workshops discussed here explore specific issues of players’ interactions with sound and auditory display design. The workshops helped move our design process forward by specifying the role of narrative and sound ecologies in our design. They clarified the role of sound in creating narrative coherence, guiding player actions, and supporting group interaction. We describe the workshops, the auditory display issues we addressed, discuss how the workshops helped inform our subsequent design, and extend recommendations on how participatory workshops can be used by other designers of auditory displays.
Bioavailable phosphorus in humic headwater streams in boreal Sweden

Bioavailable phosphorus (BAP) concentrations were determined nine times between April and October 2010 in two humic boreal headwater streams draining forest‐ and mire‐dominated catchments. BAP was analyzed in a bioassay in which natural P‐limited bacterioplankton grew with natural P as the sole P source. In both streams, approximately 90% of the BAP occurred as dissolved species (passing a 0.2‐µm filter), consisting partly of low‐molecular‐weight forms (passing a filter with nominal cutoff at 1 kDa) and partly of high‐molecular‐weight forms (passing a 0.2‐µm filter but not a 1‐kDa filter). Concentrations of total dissolved BAP varied between 1 µg L−1 and 14 µg L−1, with the highest values in the middle of the summer. Compared to the forest stream, BAP concentrations were generally higher in the mire stream, where it occasionally amounted to nearly 50% of total P. Molybdate reactive phosphorus overestimated BAP considerably. Most of the BAP was in forms other than free orthophosphate. Temporal BAP variations showed no relationships with dissolved organic carbon (C) or iron but were positively related to air temperature and negatively related to the absorbance ratio (a254 : a365) of organic compounds in the water, indicating connections between terrestrial export of BAP and temperature‐dependent terrestrial C metabolism. Concentrations of BAP can relieve stream bacteria from P limitation, and a significant share of BAP exported to streams can reach and be used in downstream lakes.
