We present a novel tightly-coupled LiDAR-inertial odometry and mapping scheme for both solid-state mechanical LiDARs. As frontend, feature-based lightweight LiDAR provides fast motion estimates adaptive keyframe selection. backend, hierarchical keyframe-based sliding window optimization is performed through marginalization directly fusing IMU measurements. For the Livox Horizon, newly released ...

information seeking anxiety can be interpreted as the fear and/or apprehension of searching for information resources during the information seeking process. the current study aims to determine the prevalence and correlates of the information seeking anxiety among a group of graduate students. the target population of the study comprised 11000 postgraduate students enrolled in various graduate ...

We present our proposal for a small X-ray mission DIOS (Diffuse Intergalactic Oxygen Surveyor) to perform survey observations of warm-hot intergalactic medium using OVII and OVIII emission lines. This will be proposed to a small satellite program planned by ISAS/JAXA in Japan for a launch in 2008. The instrument consists of an array of TES microcalorimeters with an energy resolution 2 eV, coole...

In recent years, such small body exploration missions as asteroids or comets have received remarkable attention in the world. In small body explorations, especially, detailed in-situ surface exploration by tiny rover is one of effective and fruitful means and is expected to make strong contributions towards scientific studies. JAXA/ISAS is promoting MUSES-C mission, which is the world’s first s...

Most asynchronous processor Instruction Set Architectures (ISA) are based on a single type of underlying asynchronous circuit design style. Asynchronous processor ISAs are entirely dependent on the type of asynchronous design style chosen and can support a limited set of simple applications only. Design reuse is typically difficult to realize in such cases. In this paper, we show a behavioral m...

Numerous projects have investigated assistive navigation technologies for the blind community, tackling challenges ranging from interface design to sensory substitution. However, none of these have successfully integrated what we consider to be the three factors necessary for a widely deployable system that delivers a rich experience of one’s environment: implementation on a commodity device, u...

Simulation has become one of the most timeconsuming tasks in Electronic System Level design, required both on design and verification phases. As the complexity of modelled systems increases, so do the need for adequate use of available computational resources in multiprocessor computers or clusters. SystemC simulator models are designed to use only one core, even if the hardware is multi-core. ...
