Multi-Label Zero-Shot Learning with Structured Knowledge Graphs

In this paper, we propose a novel deep learning architecture for multi-label zero-shot learning (ML-ZSL), which is able to predict multiple unseen class labels for each input instance. Inspired by the way humans utilize semantic knowledge between objects of interests, we propose a framework that incorporates knowledge graphs for describing the relationships between multiple labels. Our model learns an information propagation mechanism from the semantic label space, which can be applied to model the interdependencies between seen and unseen class labels. With such investigation of structured knowledge graphs for visual reasoning, we show that our model can be applied for solving multi-label classification and ML-ZSL tasks. Compared to state-of-the-art approaches, comparable or improved performances can be achieved by our method.Comment: CVPR 201

COMPARING THE DIFFERENCE BETWEEN FRONT-LEG AND BACK-LEG ROUND-HOUSE KICKS ATIACKING MOVEMENT ABILITIES IIN TAEKWONDO

The purpose of this study is to compare front-leg and back-leg movement abilities in Taekwondo athletes with a weight level of less than 68 kg. Six male subjects (age: 19.8±1, height: 175.6±3.9, weight: 62.5±4.8) conducted back-leg attacking movements and front-leg attacking movements with their dominant leg. The back-leg attacking movements include back leg round-house kick and strike back round house kick. The front-leg attacking movements include front leg round-house kick and slide round-house kick. From statistics obtained, the kicking of relative force, compound acceleration, and tangential acceleration are better for back-leg attacking movements. However, front-leg attacking movements are better in tangential velocity. The range of waist a rotation and the flexibility of the hip joint are important to roundhouse kick techniques to the kinetic chain

THE ADJUSTMENT OF LEG STIFFNESS DURING DYNAMIC EXERCISE AND DOWNWARD STEPPING FOR ELDERLY

The purpose of the present study was to evaluate the ability of leg stiffness regulation during downward stepping and maximal Counter-Movement-Jump (CMJ) for the elderly. Ten healthy aged people (age: 68.6±5 years; height: 165.3±4.4cm; mass: 61.7±9.3kg) and 10 students (age: 24.3±2years; height: 171.5±4.6cm; mass: 65.9±8kg) volunteered as subjects. Kistler force platform (1200Hz) and Peak high-speed camera (120Hz) were used synchronously to record the ground reaction force and the kinematic parameters of the subjects performing CMJ and stepping down from different heights. The results revealed that the elderly group has a smaller joint range of motion and greater leg stiffness than the young group during stepping down. The force and the leg stiffness during CMJ were significantly smaller for the elderly. The leg stiffness during downward stepping is independent of dynamic leg stiffness during CMJ. With aging, the adjustment ability of leg stiffness for maximal dynamic voluntary contraction was decreased

A TIME SERIOUS ANALYSIS OF THE DYNAMIC INFLUENCE OF FEMALE'S MENSTRUAL CYCLE TO SPORT PERFORMANCE

This research uses Cross Correlation Function, C.C.F., as a dynamic relationship evaluation model to study the dynamic influences of the menstrual cycle on sport performances. This research takes females with a regular menstrual cycle to be the test subjects. Their basic body temperatures were recorded every day. A Kistler Quattro Jump force plate was used to record continuously for sixty days the parameters of muscular strength, jump performance, and fatigue index during the subjects performance of a counter-movement Jump (CMJ), squat Jump (SJ), and thirty-second continuous bent leg jumps (CJB). The late stage of the follicular phase and the early stage of the luteal phase have a positive influence on sport performance. This also illustrates that sport performance for female athletes will be varied dynamically in accordance with the time of menstrual cycle

Infrared absorption of methanol-water clusters mn(h2o), n = 1-4, recorded with the vuv-ionization/ir-depletion techniques

We investigated IR spectra in the CH- and OH-stretching regions of size-selected methanol-water clusters, M$_{n}$(\chem{H_2O}) with M representing \chem{CH_3OH} and {\it n} = 1-4, in a pulsed supersonic jet by using the VUV (vacuum-ultraviolet)-ionization/IR-depletion technique. The VUV light at 118 nm served as the source of ionization in a time-of-flight mass spectrometer. The tunable IR laser served as a source of dissociation for clusters before ionization. Spectra of methanol-water clusters in the OH region show significant variations as the number of methanol molecules increase, whereas spectra in the CH region are similar. For M(\chem{H_2O}), absorption of a structure with \chem{H_2O} as a proton donor was observed at 3570, 3682, and 3722 \wn, whereas that of methanol as a proton donor was observed at 3611 and 3753 \wn. For M$_{2}$(\chem{H_2O}), the OH-stretching band of the dangling OH of \chem{H_2O} was observed at 3721 \wn, whereas overlapped bands near 3425, 3472, and 3536 \wn correspond to the OH-stretching modes of three hydrogen-bonded OH in a cyclic structure. For M$_{3}$(\chem{H_2O}), the dangling OH shifts to 3715 \wn, and the hydrogen-bonded OH-stretching bands become much broader, with a band near 3179 \wn having the smallest wavenumber. Scaled harmonic vibrational wavenumbers and relative IR intensities predicted for the methanol-water clusters with the M06-2X/aug-cc-pVTZ method are consistent with our experimental results. For M$_{4}$(\chem{H_2O}), observed spectrum agree less with theoretical predictions, indicating the presence of isomers other than the most stable cyclic one. Spectra of M$_{n}$(\chem{H_2O}) and M$_{n+1}$ are compared and the cooperative hydrogen-bonding is discussed

Development and Evaluation of an Educational Computer Game for a Certification Examination

Professional certification has become one of the important criteria for people to apply job positions in industries. Recently, computer-based learning has been widely adopted for helping students prepare for various professional certifications. However, most of the computer-based learning materials are not attractive to students, such that their learning performance is significantly affected owing to the lack of learning interests. Researchers have presented that joyful game-based learning can increase learner’s motive and pleasure. Therefore, this study builds a certification tutorial system containing two different modules that are the traditional e-version and the joyful game-based version. Moreover, an experiment has been conducted to explore the participants’ engagement and learning effectiveness of the proposed approach. Some terms are explained that the “prior knowledge” is represented by the “pre-test,” and the “level of effort” (equivalent to the “engagement”) is represented by the “experience” which is the cumulative number of correct answers. The result indicates that the traditional e-version may be slightly helpful for those participants with higher/middle prior knowledge and level of effort, and the joyful game-based version may be more helpful for those participants with lower prior knowledge and level of effort

Method development for characterizing the hydrophobicity of engineered nanoparticles

Characterizing the hydrophobicity of nanoparticles can help us understand their fate and transport in the environment, as well as how nanoparticles may interact with biological systems. However, contact angle and partition coefficient have limitations in measuring the hydrophobicity of nanoparticles, thus promising methods to measuring the hydrophobicity of nanoparticles are needed. Hydrophobic interaction chromatography (HIC) and dye adsorption were used to test the hydrophobicity of nanoparticles in this study. HIC used hydrophobic interaction between hydrophobic ligand and nanoparticles to determine hydrophobicity of nanoparticles. The hydrophobicity of carboxylated nanocrystalline cellulose (CNC) is pH dependent and was used to assess the sensitivity of HIC assay. Relative hydrophobicity of metal oxides can be related to their isoelectric point (IEP) was supported by HIC. Besides, the surface coatings dominated the hydrophobicity of nanoparticles was also discussed. Dye adsorption studies were conducted using gold nanorods. By amount of hydrophobic dye adsorbed on to nanoparticles can determine their hydrophobicity. Comparing these two methods, dye adsorption can show the continuum from the hydrophobic to hydrophilic and quantified the hydrophobicity, thus it is a more promising way to measure the nanoparticle hydrophobicity than HIC
