We are developing transition edge sensor with a superconducting high-Z metal bulk absorber for high energy resolution spectroscopy of hard X-ray and gamma-ray within 100 keV ~ 1 MeV. applied tantalum it has low heat capacity absorption efficiency to photons. As result an experiment using from <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">137</sup> Cs, that is better than Ge semiconductor detector was achieved at 662 keV. In addition, we...
We have designed and fabricated a hard X-ray gamma-ray TES spectrometer for nuclear materials analysis. A superconducting tin (Sn) absorber is coupled to the film by using gold (Au) bump post improve thermal contact between TES. To obtain sufficient detection efficiency at high energy photons near 100 keV, an 8-pixel array of microcalorimeters were developed. In this new device, epoxy glue which used connect was well controlled hence slow component decay time constant improved from 7.82 ms...
When people are talking together in front of digital signage, advertisements that aware the context dialogue will work most effectively. However, it has been challenging for computer systems to retrieve appropriate advertisement from among many options presented large databases. Our proposed system, Conversational Context-sensitive Advertisement generator (CoCoA), is first attempt apply masked word prediction web information retrieval takes into account context. The novelty CoCoA advertisers...
In this work, we present a system that sequentially generates advertisements within the context of dialogue. Advertisements tailored to user have long been displayed on digital signage in stores, web pages, and smartphone applications. will work more effectively if they are aware dialogue between users. Creating an advertising sentence as query searching by using is one way variety advertisements, but there currently no method create appropriate search for accordance with context. Therefore,...
When individuals are talking while performing multiple tasks at the same time, it is sometimes easy to miss parts of a conversation and misinterpret subsequent statements or have difficulty following conversation. In this work, we aim identify that may lead misinterpretation statement if missed prevent communication discrepancies. Although there been several attempts present images text provide topics support conversation, currently no system supports by taking interpretability into account....
A phase transition occurring at 320 K in DCrO 2 but not HCrO has been investigated by infrared spectroscopy. The hydrogen bond bending vibration is sensitive to the transition, peak frequency changing sharply with temperature temperature. Cr-O region also absorption 434 cm− 1 for .below examined closely respect intensity and band width. Dispersion-like anomalies spectra (the Evans-Fano effect) have studied analysis of spectral shape function.
We propose a novel approach to embedding sentences into high-dimensional space. Independent words in the sentence are located at points space, and is represented by curve along these words. A set of functions that evaluates sequence designed over this space helpful for searching likely follow observed sentences. More generally, our makes sequentially depending on context. simplify Japanese grammar subsequently implement it as constrains simple be generated. In study, we performed experiments...
Tournament systems in sports contests need to reflect players' performance appropriately as well draw people's interest. In this study, we formulate the relationship between strengths and winning probabilities based on Elo rating system. We propose a scale for evaluating extent which tournament system reflects strength of players. To calculate concretely, explain three approaches. then conduct web survey investigate judgments ability dominance interestingness systems. simulate number types...
Interest in watching sports is supposed to depend on uncertainty of the winner. Displaying probability information middle match possibly make audiences get interested if consistent with their intuition. To test this hypothesis, volleyball videos are captioned winning probabilities based different models; one statistical data while other not. These shown participants and rated for interestingness consistency displayed predictions. The results show that average does not significantly differ...
Recently much interest has been aroused by L10 ordered FePt thin films due to their large magnetocrystalline anisotropy, which is required for ultra-high-density magnetic recording media. The grain size of pure fairly large, can cause medium noise and a reduction resolution. We prepared FePt-Al2O3 the in-situ ordering method, aiming suppress growth transforming disordered fcc phase into structure.

In this paper, we construct 6 types of multi-class classifiers and compare the performance them. feature extraction phase, CSP filter (common spatial pattern filter) PCA (principle component analysis) LDA (linear discriminant are used. classification kNN (k-nearest neighbor) method SVM (support vector machine) As a result, best classifier for discriminating grasping patterns was CSP/kNN (We set selective number k as 1). The rate 9-class power-type 48% 7-class precision-type 40%.
During remote conversations, communication breakdowns often occur when a listener misses certain statements. Our objective is to prevent such by identifying Statements Crucial for Awareness of Interpretive Nonsense (SCAINs). If SCAIN, s/he may interpret subsequent statements differently from the speaker's intended meaning. To identify SCAINs, we adopt unique approach where create dialogue omitting two consecutive original and then generate text make following statement more specific. The...
In this experiment, Fe:Cu granular precursor is first deposited; FePt:Cu films are successfully prepared by interlayer diffusion of the layer and a second Pt. This technique provided more degree freedom on preparation artificially films. The preparation, structure, magnetic properties have been investigated.
While sports games in which both competitors have an equal chance to win are preferred by audiences, it is often easy predict the winners tennis matches. On other hand, some audiences interested players' athletic quality as well player will win. Whether individual focuses on primary attributes such winner or secondary performance depends construal level. Thus we tested whether manipulating level can make a one-sided match. We conducted experiment with participants evaluate excitement at...
To create dialogue systems that provide information a user needs to know at an opportune moment, it is important infer the user's mental states such as his/her beliefs and desires. There are two types of study on inferring desires: one type infers them from actions other content utterances. However, method desires both kinds inference in integrated way has not yet been established. In this paper, we propose Multimodal Inference Mind Simultaneous Contextualization Interpreting (MIoM SCAIN),...
