We report the discovery of a high-temperature source above soft X-ray loop impulsive limb flare on 1992 January 13 with Yohkoh Soft Telescope (SXT). The hot coincides in position loop-top hard and continues to sit throughout flare. single initial phase evolves two (15-20 MK) ridge structures peak decay phases, compact appears be located between ridges. assume that is thermal origin (superhot source). has an effective temperature 100-150 MK total emission measure ~10-4 source. geometrical...
In this paper, an architectural level processor design environment PEAS-III is proposed. Pipelined processors designed by system can include multi-cycle operation, delayed branch and external interrupt. The data path control logic of the are generated from clock based micro-operation description instructions. ease large space exploration through experiments using several subsets MIPS R3000 instruction set.
The Hard X-ray Telescope (HXT) on board Yohkoh is a Fourier-synthesis-type imager for solar flare observations; it measures set of spatially modulated photon counts with sixty-four, independent, bigrid modulation collimators and an image reconstructed from these data using sophisticated synthesis procedures, such as the Maximum Entropy Method (MEM) PIXON. HXT-MEM imaging has been greatly improved by incorporating following three improvements which we have recently achieved: (1) Accurately...
A novel framework for ASIP (application specific integrated processor) development is proposed. The system accepts a set of example programs written in the C language and their expected data as input, profiles these both statically dynamically. Then taking advantage profiled results, decides instruction hardware architectures ASIP, synthesizes CPU core design well software tools such compiler simulator.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML"...
The flavor of Japanese sake (frequently referred to as Seisyu in academic contexts) has improved recent years and demand for is on the rise globally. Our analysis based a review literature secondary data examination existing statistics. Quality control achieved through use acid from polished rice. One may be rice flavors, which are regionally specific therefore lead reconsideration geographical indications. collaboration with local regional community observed wine production. Similar...
The current implementation and experimental results of the PEAS-1 (practical environment for application specific integrated processor (ASIP) development - Version I) system are described. PEAS-I is a hardware/software co-design ASIP development. input to set programs written in C language, an associated data set, design constraints such as chip area power consumption. generates optimized CPU core form HDL, well program tools, compiler, assembler, simulator. A novel method that formulates...
The skills of OT(Operational technology) security, has been practiced in the education ICT and spread security knowledge, only a small number specialist training is insufficient. In addition, OT that emphasizes availability, to improve experts some non-IT officials, but exercises using actual equipment appropriate, it practically difficult. Therefore, order skills, necessary practice countermeasures know incidents same situation as reality, learn cooperation by teamwork while improving...
We analyzed Hard X-Ray Telescope observations of an X1.2 flare on 1998 April 23. This is one the best examples for studying coronal hard X-ray sources due to intensity emission and occultation footpoints. In this flare, composed both thermal nonthermal emissions showed complex structure unlike any previously observed. Dominant do not come from same loop-top region. Nonthermal include two in low corona (~2.7 × 103 km) extended source high (~5 104 km). These suggest that energetic phenomena...
In this paper, we propose a method for detecting abnormal driving of vehicles, such as meandering, transverse motion and acceleration/deceleration. particular, extract vehicle motions in the sense group behavior by using multilinear relationship space-time images. The images holds when multiple cameras move with translational different direction speed. Therefore drivings, which are not uniform velocity, do meet requirement, does hold. We focus on property, define degree abnormality, is used...
In this paper, we consider uncalibrated reconstruction of curved surfaces from apparent contours. Since contours are not fixed features (viewpoint independent), cannot directly apply the recent results features. We show that, nonetheless, can be reconstructed up to an affine ambiguity their viewed cameras with unknown linear translations. Furthermore, even if is nonmetric (non-Euclidean), still extract useful information for many computer vision applications just first that camera motion...
We use high-resolution radio observations to study the physical parameters of a flaring loop. The loop is visible at wavelengths because gyrosynchrotron emission by nonthermal electrons (energies typically above several hundred keV) accelerated flare. are able measure thickness and length with precision on order 1''. find that increases from about 60'' initially 80'' in decay phase event. (averaged along its length) no more than 3'' wide. soft hard X-ray data obtained Soft X-Ray Telescope...
We have discovered two molecular features at radial velocities of −35 km s−1 and 0 toward the infrared Double Helix Nebula (DHN) in Galactic center with NANTEN2. The show good spatial correspondence DHN. also found elongated ridges these distributed vertically to plane over 08. are linked by broad velocity likely connected physically each other. ratio between 12CO J = 2–1 1–0 transitions is 0.8 which larger than average value 0.5 foreground gas, suggesting center.
