Ground Targets Recognition from Flying Vehicles usingCamera/SAR Imaging Systems

This paper proposes a ground targets recognition system for flying vehicles using Camera/Synthetic Aperture Radar (SAR) imaging systems. The proposed method is an image processing technique to improve the precision of the INS for detecting and tracking the ground objects from flying vehicles. Template matching is one of the methods used for ground object detection and tracking. Synthetic Aperture Radar (SAR) is also used as ground object detection with ATR technique. Robust and reliable object detection is a critical step of object recognition. Our focus is on flying systems equipped with camera and SAR to capture photos for the ground and recognize it. SAR is a type of imaging radar in which the relative movement of the antenna with respect to the target is utilized. Through the simultaneous processing of the radar reflections over the movement of the antenna via the Range Doppler Algorithm (RDA). The proposed method is independent on the altitude or the orientation of the object. The algorithm is simulated using Matlab program and the numerical experiments are shown which verify the object detection for a wide range altitude and orientation. The results show superiority of this method for identifying and recognizing the ground objects.
Extra-virgin olive oil and its phenolic extract prevent inflammatory response and joint damage in murine experimental arthritis *

The consumption of EVOO in Mediterranean countries has shown beneficial effects. A wide range of evidence indicates that the phenolic compounds present in EVOO are endowed with anti-inflammatory properties. In this work, we evaluated the effects of dietary EVOO and treatment with its phenolic extract (PE) in a model of RA, the collagen-induced arthritis (CIA) in mice. On day 0, DBA-1/J mice were immunized with bovine collagen type II (CII). On day 21, the mice received a booster injection. We have demonstrated that EVOO and its PE decreases joint edema, cell migration, cartilage degradation and bone erosion. Our data indicate that dietary EVOO and PE treatment inhibit JNK, p38 and signal transducer and STAT-3. In addition, both EVOO and PE decrease NF-κB translocation leading to the down-regulation of the arthritic process. These results support the interest of natural diet components in the development of therapeutic products for arthritic conditions.
DIN, DON and P04 flux by a medusa with algal symbionts

Linuche unguiculata, a coronate scyphozoan with symbiotic dinoflagellates (= zooxanthellae), was shown to be capable of taking up NH4, NO3, PO, and 3 amino acids from seawater. The algae constitute 32 % of the total organismal nitrogen. Both depletion and uptake experiments showed the flux of NH, to be more than that of NO3. Rates of 1 5 N ~ , uptake by freshly isolated zooxanthellae were comparable to those for free-living phytoplankton, but I5NO3 uptake was much lower. Medusae held In the dark several days demonstrated a substantial decrease in their uptake (or depletion) of NH4 and PO,. The uptake of 15~l abe l l ed glycine and leucine and 14C-labelled alanine was measured at a range of concentrations at rates similar to those measured for NH,. Frachonation procedures after uptake experiments showed that both non-algal and zooxanthellae fractions were labelled wlthin a few minutes but 15N from NH4 appeared preferentially in the zooxanthellar fraction whereas nitrogen from amino acids went primarily to the non-algal (supernatant) fraction. Specific uptake rates of DIN, DON and PO, by intact L. unguiculata at ambient concentrations were calculated to be about 1 % d-' for nitrogen and 3.6 % for phosphorus. Although independent measurements of growth and reproductive demands for L. unguiculata imply that ingestion of particulate food 1s likely to be the major source of nutrients, the presence of zooxanthellae enables the medusae to conserve nutrients by preventing their loss from the association.
Study of CP Property of the Higgs at a Photon Collider using → t¯ → lX

We study possible effects of CP violation in the Higgs sector on t¯ t production at a collider. These studies are performed in a model-independent way in terms of six form-factors {ℜ(S), ℑ(S), ℜ(P), ℑ(P),St,Pt} which parametrize the CP mixing in the Higgs sector, and a strategy for their determination is developed. We observe that the angular distribution of the decay lepton from t/¯ produced in this process is independent of any CP violation in the tbW vertex and hence best suited for studying CP mixing in the Higgs sector. Analytical expressions are obtained for the angular distribution of leptons in the c.m. frame of the two colliding photons for a general polarization state of the incoming photons. We construct combined asymmetries in the initial state lepton (photon) polarization and the final state lepton charge. They involve CP even (x’s) and odd (y’s) combinations of the mixing parameters. We study limits up to which the values of x and y, with only two of them allowed to vary at a time, can be probed by measurements of these asymmetries, using circularly polarized photons. We use the numerical values of the asymmetries predicted by various models to discriminate among them. We show that this method can be sensitive to the loop-induced CP violation in the Higgs sector in the MSSM.
Verification of the MeteoExpert Nowcasts

The MeteoExpert system was operational at the Main Operations Center of Sochi-2014 Olympic and Paralympic Games. The MeteoExpert provided information support round the clock for forecasters, referees and organizers of the Olympic and Paralympic Games via MeteoExpert web site and FROST-2014 web site. The MeteoExpert generated pointwise time series of meteorological variables for five Olympic venues in mountain cluster with four hour lead time and update cycle of ten minutes. They were based on local observations including automatic weather stations (AWS) and Doppler weather radar, and numerical atmospheric boundary layer (ABL) model. Nowcasts have been verified against actual observations at the sites where automatic weather stations exist.
Galaxy Evolution through Far-Infrared Radiation

About half of the radiative energy from galaxies is emitted in the far-infrared (FIR) wavelength. The FIR radiation originates from the reprocessing of stellar light by dust grains. In order to reveal the time evolution of dust content in galaxies, we construct an evolution model of dust-to-gas mass ratio by extending the chemical evolution model and by considering the formation and destruction processes of dust. Based on this model, we succeed in explaining the relation between dust-to-gas ratio and metallicity for galaxies with a wide metallicity range, which confirms that our model describes the evolution of dust content of galaxies in various evolutionary stages. The evolution of interstellar medium (ISM) may be important in the time evolution of dust-to-gas ratio. This is because the dust growth occurs only in the cold and dense phase of the ISM. We discuss the time variation of dust-to-gas mass ratio using the three-phase model of the ISM. The typical timescale of the phase change of an interstellar gas is rv 1078 yr in spiral galaxies. Since the phase transition changes the filling factor of the cold gas where the dust growth occurs, the dust growth rate varies on that timescale. We examine the response of the dust-to-gas ratio to the phase transition by adopting the Ikeuchi-Tomita model for the mass exchange among the phases. According to the model, a limit-cycle evolution of the mass exchange is obtained. In this limit-cycle case, the amplitude of the variation of the dust-to-gas ratio is large (nearly an order of magnitude) if the dust growth timescale is shorter than the phase transition timescale. Since this condition is easily satisfied in spiral galaxies, the dynamical multi-phase evolution of ISM is important for the time evolution of dust amount. The dust amount is important for the intensity of its thermal radiation at FIR. Although FIR emission from dust is frequently used as an indicator of star formation rate (SFR), the effect of the dust-to-gas ratio (i.e., amount of the dust) on the conversion law from IR luminosity to SFR has not so far been considered. Then, we present a convenient analytical formula including this effect. Especially, we present the metallicity dependence of our conversion law between SFR and FIR luminosity with the aid of our model. We find that the effect of the chemical evolution on the conversion formula is significant: The conversion factor from FIR luminosity to SFR changes by a factor of 4 in the course of chemical enrichment. This is important in determining the cosmic SFR from the future FIR observations (e.g., ASTRO-F). Finally, we consider the observational strategy with ASTRO-F, which will be launched in 2004. This satellite enables us to test our galaxy evolution model in the FIR wavelength. One of the main purposes of the ASTRO-F mission is an all-sky survey in the FIR with a flux limit more than ten times deeper than that of IRAS. We investigated the expected optical and near-infrared (NIR) number counts of galaxies detected by the FIR scanner (FIS) of ASTRO-F and the possibility of their optical and NIR follow-up.

How can visual experience be depicted? A study of close-up double vision

The attempt to record visual experience has been of central importance to many artists throughout the history of art. Vision itself is made up of many processes, both psychological and physiological, and is still only partially understood. This paper presents research into an aspect of visual experience descried as ‘close-up double vision’, which has been directly informed by the artwork of the Swansea born artist Evan Walters. Close-up double vision occurs when an object is seen extremely close to a viewer whose eyes are not both fused on the object concerned, creating a doubling effect in the visual field. Walters termed this doubling effect caused by lack of binocular fusion ‘double vision’ and spent much of the latter part of his career trying to record it. This paper briefly introduces Walters’ experiments in double vision and outlines current research that attempts to record this aspect of visual experience in artworks.
A Fast Vehicle Detection Method for Road Monitoring

To address the issue that current traffic monitoring system needs to automatically detect the objects on the road, a fast vehicle detection method was proposed. Applied the YOLO framework, this paper considered the vehicle detection as a regression problem of vehicle location prediction and classification prediction. Under the precondition of guaranteeing accuracy, the structure of convolution neural network (CNN) is optimized to speed up the detection. The vehicle model CarNet was trained on a dataset containing a large number of road vehicle sample images. The experimental results show that with this method vehicle in video can be detected quickly even on a computer without GPU. The method also shows good robustness and high precision.
Middle School Art - One Picture is Worth a Thousand Words

The experiences they have here in art may make lasting impressions on an area that will touch them the rest of their lives. Artistic Development of the Middle School Student In the middle school, from the art teacher's point of view, every child is "new born. " Emotional, generally wkward, often poorly coordinated, the early adolescent is likely to produce immature artistic expression. It is easy for the early adolescent artist to become discouraged when successful art forms of previous years are no longer acceptable to him or her. Depending on the amount of art instruction in the elementary school, early adolescent artists may not have discovered their artistic potential and be discouraged with their immature attempts at creating art. Lowenfeld (1952), a pioneer in the development of stages of artistic and creative development, labeled this age group as the "gang-age" or more formally, "the Stage of Realism. " These students have a keen interest in realistic art, art that "looks like it is supposed to look. " They are trying to understand how the world looks and want their art to look that
Are the Swimming Kinematics of Blind Cavefish Adapted for Active Flow-sensing?

Sheryl L. Coombs, Advisor When visual cues are poor or unavailable, animals often rely on a form of active sensing in which they produce their own signal energy to probe various features of the environment (e.g. echolocation by bats). In a different and less-understood form of active sensing, blind cavefish use their burst and coast swimming motions to generate flow signals that can be detected by the lateral line. The coast phase of the swimming cycle produces a relatively stable, dipole-like flow signal that is distorted when fish swim by nearby obstacles. In this study, we test the hypotheses that (a) blind cavefish have evolved behavioral specializations for active flow-sensing compared to their nearest sighted relatives (a morph of the same species) and (b) flow signal production is regulated by lateral line sensory feedback. We compared the swimming kinematics of blind and sighted morphs in response to a novel, dark environment – both before (T1) and after (T2) a 24hr familiarization period and with and without a functional lateral line. There were two major findings of this study. The first was that the majority of burst-coast kinematic parameters exhibited no significant differences as a function of morph, familiarity with environment or lateral line functionality. Noteable exceptions included an increase in coast duration, coupled with a decline in swim cycle frequency after T2 for both morphs. The second major finding was that blind morphs exhibited a significantly higher incidence of swim cycles that formed part of a straight swimming trajectory. Both lateral line deprivation and familiarization in the arena led to significant declines in this number for blind, but not sighted morphs. Taken together, these results suggest that both morphs have inherited common neuroethological strategies for regulating burst-coast swimming kinematics, but that blind morphs differ significantly from

Elliptic algebra, Frenkel–Kac construction and root of unity limit

We argue that the level-1 elliptic algebra Uq,p(g^) is a dynamical symmetry realized as a part of 2d/5d correspondence where the Drinfeld currents are the screening currents to the q-Virasoro/W block in the 2d side. For the case of Uq,p(sl^(2)), the level-1 module has a realization by an elliptic version of the Frenkel–Kac construction. The module admits the action of the deformed Virasoro algebra. In a rth root of unity limit of p with q2→1, the Zr-parafermions and a free boson appear and the value of the central charge that we obtain agrees with that of the 2d coset CFT with para-Virasoro symmetry, which corresponds to the 4d N=2 SU(2) gauge theory on R4/Zr.
Organic Food: An Assessment of Knowledge of Homemakers and Influencing Reasons to Buy / Not to Buy

Abstract Serious concerns expressed during the last decade regarding the use of chemicals in agriculture in terms of their adverse impact on the human health, environment and sustainable agricultural production has been encouraging organic food production world over. The food thus produced has minimal elements harmful to the human health. Hence apart from being environment friendly, organic foods are believed to be having high nutritional value and safe for human health. But how far the women, the health providers of families, are aware of various aspects of organic food needs to be investigated so as to increase the consumption of organic food products. Some areas of India have popularized organic food. With a view to find out the scenario in Gujarat, a small study was conducted in Vadodara city to assess the knowledge of homemakers about organic food and the reasons for buying/not buying organic food. Through an interview schedule, data were collected from a sample of 110 homemakers randomly selected from 3 localities of Vadodara city. Majority of them had good knowledge about organic food but majority of them did not buy organic food as it was not easily available, was required in larger quantity and was not so good in appearance as compared to conventional food items. Lack of standardization mark/certification process also demotivated them to purchase the organic food. The study revealed a need for having more organic food bearing standardization mark.
Liquidity Constraints, Interest Rates and Optimal Credit Subsidies

There is an ongoing debate about whether credit subsidies improve welfare or not. We build a model of monopolistic competition with liquidity constrained firms to analyze the optimal credit subsidy policy. The contribution of this paper is to determine the role of interest rates on optimal credit subsidies. This paper shows that i) there exists an optimal credit subsidy level which always increases welfare; ii) however, some subsidy levels can decrease welfare compared to no policy case, and iii) the market interest rate plays a crucial role in determining the optimal level for credit subsidy.

Experimental determination of viscoelastic properties of a highly compressible porous materials imbibed with water

The experimental study of a highly compressible porous material, made of cellulose fibers, and imbibed with water, during stress relaxation tests on a rheometer, shows that the material relaxes when kept at constant strain as long as there are open pores. Using the relaxation curves, the behaviour under compression can be divided into two distinct zones, a poro-elastic one and a purely-elastic one, bounded by the zero-porosity limit. In the poro-elastic zone, the "non-hookean" stress-strain curve is fitted using Spriggs' expression of the elastic modulus dependence with porosity. Therefore, the elastic modulus of the porous material is expressed as an exponential function with two parameters: the elastic modulus of the fibers and the initial porosity of the material. For the purely - elastic zone the variation of stress is expressed as a sum of the residual stress obtained from the continuity equation and a Hookean stress- strain variation of a thinner material with the elastic modulus of the fibers - determined previously. The relaxation curves are fitted with a relationship between the decay stress and time, approximated with three terms of Prony series expansion of the generalized Maxwell model.
Internet sport bloggers: Who are these people and where do they come from?

Little is known of Internet sport bloggers, who increasingly are becoming important cogs in sport journalism. In this phenomenology, semi-structured interviews were conducted with highly prominent sport bloggers. All were recorded, transcribed, and coded. A total of five dominant themes emerged from the data that focused on the shared experiences and learned attitudes toward Internet sport journalism. Overall, these themes showed sport bloggers were highly educated and very happy with their jobs, had a wide array of past work experiences that often had little to no relation with blogging or sport journalism, consider their jobs too varied to fall under one title, primarily work from home, and rarely attend sporting events they write about.
