Opis:
In order to realize a system that supports human actions timely, the system must have a certain model of human actions. Therefore, we propose a modeling method of human actions. In this method, it is supposed that a person changes his action according to the situation around him, and the causality between the situation around a person and the change of a human action is modeled. This causality is expressed by an If-then-Rule style where a human action and the situation around a human are expressed by a discrete event and time series data respectively. Moreover, as the necessary function for human support systems, an estimation method of the next human action and its execution timing is consisted based on the proposed modeling method. The usefulness of the proposed modeling and estimation methods is examined through the estimation experiment of next human action and its execution timing with a radio-controlled vehicle.

Opis:
Our effort for decontamination of radioactive cesium scattered widely by nuclear accident in March 2011 in Fukushima, Japan has been described. Radioactive cesium scattered widely in Japan has been accumulating in arc or plasma molten-solidified ash in waste incinerating facilities up to 90,000 Bq/kg of the radioactive waste. Water rinsing of the ash resulted in dissolution of cesium ions together with high concentrations of potassium and sodium ions. Although potassium inhibits the adsorption of cesium on zeolite, we succeeded to precipitate cesium by in-situ formation of ferric ferrocyanide and iron rust in the radioactive filtrate after rinsing of the radioactive ash with water. Because the regulation of no preservation of any kind of cyanide substances, cesium was separated from the precipitate consisting of cesium-captured ferric ferrocyanide and ferric hydroxide in diluted NaOH solution and subsequent filtration gave rise to the potassium-free radioactive filtrate. Cesium was captured by zeolite from the potassium-free radioactive filtrate. The amount of this final radioactive waste of zeolite was significantly lower than that of the arc-molten-solidified ash.
Opisano wysiłki podjęte po awarii nuklearnej w marcu 2011 w Fukushimie, Japonia. Radioaktywny cez rozproszony na znacznym obszarze Japonii jest akumulowany do poziomu 90,000 Bq/kg w spalarniach śmieci w procesie stapiania w łuku plazmy radioaktywnych śmieci. Przemywanie wodą popiołów powoduje wymywanie radioaktywnego cezu wraz ze znacznymi ilościami potasu i sodu. Ponieważ potas inhibituje adsorpcję cezu na zeolitach, udało się stracić cez w postaci kompleksu z żelazo żelazicyjankiem oraz tlenków żelaza w przesączu po przemywaniu radioaktywnego popiołu. Ustawodawstwo zakazuje przechowywania jakiejkolwiek substancji zawierającej grupę cyjanową, dlatego otrzymany osad rozpuszczono stosując rozcieńczony NaOH. Ponowna filtracja doprowadziła do uzyskania radioaktywnego przesączu nie zawierającego jonów potasu. Następnie radioaktywny cez został zaadsorbowany na zeolitach. Końcowa ilość radioaktywnych zeolitów była znacząco mniejsza od popiołów.

Opis:
Extrapolation of world energy consumption from 1990 to 2010 indicates the complete exhaustion of world reserves of oil, natural gas, uranium and coal by 2040, 2043, 2046 and 2053, respectively. For the survival of all people in the whole world, intermittent and fluctuating electricity generated from renewable energy should be supplied in the form of usable fuel to all people in the whole world. We have been working on research and development of global carbon dioxide recycling for the use of renewable energy in the form of methane via electrolytic hydrogen generation using carbon dioxide as the feedstock. We created energy-saving cathodes for hydrogen production, anodes for oxygen evolution without chlorine formation in seawater electrolysis, and catalysts for methanation of carbon dioxide and built pilot plants of industrial scale. Recent advances in materials are described. Industrial applications are in progress.
Ekstrapolacja światowego zużycia energii z lat 1990-2010 wskazuje, że całkowite wyczerpanie światowych zasobów ropy naftowej nastąpi w 2040 roku, gazu ziemnego w 2043 roku, uranu w 2046 roku a węgla w 2053 roku. Dla przetrwania ludzkości na całym świecie energia elektryczna powinna być generowana z odnawialnego zródła w formie paliwa dostępnego dla kazdego. Opracowano technologie globalnego recyklingu dwutlenku wegla i zastosowania metanu jako formy odnawialnej energii generowanej poprzez uwodornienie CO2 wodorem produkowanym podczas elektrolizy wody morskiej. Opracowano energooszczedne katody do produkcji wodoru, anody do produkcji tlenu bez towarzyszącej temu emisji gazowego chloru podczas elektrolizy wody morskiej oraz katalizatory stosowane w procesie uwodornienia dwutlenku węgla. Wybudowano również pilotażowa instalacje w skali przemysłowej. Praca opisuje ostatnie postępy w industrializacji procesu.

Opis:
We have been studying the high-precision three-dimensional measurement system using cameras. In this paper, our system is verified, and its application is reported. The principle of our measurement system is based on the stereo measurement. In our system, reducing the quantization error by numerical processing can realize the highprecision 3D measurement at the long distance. This measurement system has many applications, such as industrial use, ITS, robotics, and many others. Our system has been applied on the observation of the glacier. The Perito Moreno glacier, which is our target, moves very fast and the moving speed is reported as about 2 m/day. Then, it is thought that the important information about the global warming can be obtained by observing this glacier. But, as the width of the glacier is several km, there were no reports of continuously observing the movement of the glacier in high accuracy. As a result, the unique observation results about the daily movement of the glacier were measured. The observation of the glacier flow was carried out for the third straight year. In this paper, the valuable results of the glacier observation and experimental results to verify the precision are discussed.

Opis:
The North Ecliptic Pole field is a natural deep-field location for many satellite observations. It has been targeted many times since it was surveyed by the AKARI space telescope with its unique wavelength coverage from the near- to mid-infrared (mid-IR). Many follow-up observations have been carried out, making this field one of the most frequently observed areas with a variety of facilities, accumulating abundant panchromatic data from the X-ray to the radio wavelength range. Recently, a deep optical survey with the Hyper Suprime-Cam (HSC) at the Subaru telescope covered the NEP-Wide (NEPW) field, which enabled us to identify faint sources in the near- and mid-IR bands, and to improve the photometric redshift (photo-z) estimation. In this work, we present newly identified AKARI sources by the HSC survey, along with multiband photometry for 91 861 AKARI sources observed over the NEPW field. We release a new band-merged catalogue combining various photometric data from the GALEX UV to submillimetre (sub-mm) bands (e.g. Herschel/SPIRE, JCMT/SCUBA-2). About ∼20 000 AKARI sources are newly matched to the HSC data, most of which seem to be faint galaxies in the near- to mid-infrared AKARI bands. This catalogue is motivating a variety of current research, and will be increasingly useful as recently launched (eROSITA/ART-XC) and future space missions (such as JWST, Euclid, and SPHEREx) plan to take deep observations in the NEP field.

Opis:
Galaxy clusters provide an excellent probe in various research fields in astrophysics and cosmology. However, the number of galaxy clusters detected so far in the AKARI North Ecliptic Pole (NEP) field is limited. In this work, we provide galaxy cluster candidates in the AKARI NEP field with the minimum requisites based only on the coordinates and photometric redshift (photo-z) of galaxies. We used galaxies detected in five optical bands (g, r, i, z, and Y) by the Subaru Hyper Suprime-Cam (HSC), with additional data from the u band obtained from the Canada-France-Hawaii Telescope (CFHT) MegaPrime/MegaCam, and from the IRAC1 and IRAC2 bands from the Spitzer space telescope for photo-z estimation. We calculated the local density around every galaxy using the 10th-nearest neighbourhood. Cluster candidates were determined by applying the friends-of-friends algorithm to over-densities. A total of 88 cluster candidates containing 4390 member galaxies below redshift 1.1 in 5.4 deg2 were identified. The reliability of our method was examined through false-detection tests, redshift-uncertainty tests, and applications on the Cosmic Evolution Survey (COSMOS) data, giving false-detection rates of 0.01 to 0.05 and a recovery rate of 0.9 at high richness. Three X-ray clusters previously observed by ROSAT and Chandra were recovered. The cluster galaxies show a higher stellar mass and lower star formation rate compared with the field galaxies in two-sample Z-tests. These cluster candidates are useful for environmental studies of galaxy evolution and future astronomical surveys in the NEP, where AKARI has performed unique nine-band mid-infrared photometry for tens of thousands of galaxies.
