An accurate forecasting system is extremely crucial in order to simulate an optimum output level of photovoltaic (PV) power production for the next day. In this study, a relatively high-precision model solar irradiance based on grid point value (GPV) datasets using relative humidity, precipitation, and three-level cloud covers parameterization has been conducted Hitachi four main cities Japan. case cloudy/rainy/snowy days, influence liquid water path further introduced model. As result,...
Abstract. With the spread of Mobile Laser Scanning (MLS) system, demands for management road and facilities using MLS point clouds have increased. Especially, pole-like objects such as streetlights, utility poles, street signs etc. are in high demand to be managed. We propose a method recognizing from clouds. Our is based on Laplacian smoothing k-nearest neighbors graph, Principal Component Analysis points objects, thresholding degree objects. can robustly recognize with various radii tilt...
An advanced prototype of a digital pixel calorimeter, EPICAL-2, has been constructed using ALPIDE MAPS sensors. It successfully tested with cosmic muons and test beams at DESY the CERN SPS. We will report on recent updates performance results, good linearity resolution. Comparisons to detailed MC simulations are made show understanding technology. The spatial precision event-by-event measurements showers allows unprecedented studies shower shape. detector features two-shower separation...

Abstract The first evaluation of an ultra-high granularity digital electromagnetic calorimeter prototype using 1.0–5.8 GeV/c electrons is presented. 25 × 10 6 pixel detector consists 24 layers ALPIDE CMOS MAPS sensors, with a pitch around 30 μm, and has depth almost 20 radiation lengths tungsten absorber. Ultra-thin cables allow for very compact design. properties that are critical physics studies measured: shower response, energy resolution linearity. stochastic comparable the state-of-the...
Proton computed tomography (pCT) and radiography (pRad) are proposed modalities for improved treatment plan accuracy in situ validation proton therapy. The pCT system of the Bergen collaboration is able to handle very high particle intensities by means track reconstruction. However, incorrectly reconstructed secondary tracks degrade image quality. We have investigated whether a convolutional neural network (CNN)-based filter improve quality.The CNN was trained simulation reconstruction tens...
A prototype of a new type calorimeter has been designed and constructed, based on silicon-tungsten sampling design using pixel sensors with digital readout. It makes use the Alpide MAPS sensor developed for ALICE ITS upgrade. binary readout is possible due to size $\approx 30 \times \, \mu \mathrm{m}^2$. This successfully tested cosmic muons test beams at DESY CERN SPS. We report performance results obtained DESY, showing good energy resolution linearity, compare detailed MC simulations....
Characterization of the functional relationship between sensory inputs and neuronal or observers' perceptual responses is one fundamental goals systems neuroscience psychophysics. Conventional methods, such as reverse correlation spike-triggered data analyses are limited in their ability to resolve complex inherently nonlinear neuronal/perceptual processes because these methods require input stimuli be Gaussian with a zero mean. Recent studies have shown that based on generalized linear...

Urban environmental issues related to heat and aerial pollutants have become increasingly more serious. Atmospheric properties, such as air temperature, wind velocity, pollutant concentrations, are typically measured at meteorological observation stations. However, due the low spatial resolution of station networks, we cannot observe local occurring on scale people's daily lives. Thus, mobile measurement is an effective method for addressing insufficient points in urban areas. extent Global...
In this paper, we propose a mixture of probabilistic partial canonical correlation analysis (MPPCCA) that extracts the Causal Patterns from two multivariate time series. patterns refer to signal within interactions elements having multiple types mutually causal relationships, rather than simultaneous correlations or absence presence relationship between elements. statistics, (PCCA) evaluates multivariates after subtracting effect third multivariate. PCCA can calculate Granger Causal- ity...
In this work, we present a multimodal system for active robot-object interaction using laser-based SLAM, RGBD images, and contact sensors. the object manipulation task, robot adjusts its initial pose with respect to obstacles target objects through data so it can perform grasping in different configuration spaces while avoiding collisions, updates information related last steps of process sensors hand. We series experiment evaluate performance proposed following RoboCup2018 international...
Aluminum nitride (AlN) is widely used in the field of electronics because it has high thermal conductivity, good electric and mechanical properties. On other hand a shortcoming being difficult to wet metals. Therefore, various contrivances are needed form metal film with adhesion strength on AlN surface.
