動画像は，昨今，人工知能での利活用もあいまってエンターテインメント分野のみならず，防災やインフラ維持管理などでの利活用が広がっている．一方で，一般のカメラには，GNSS受信機・アンテナがついていたとしても，１周波のものがほとんどで，撮影場所を特定し，維持管理等に利用するには精度が十分でないケースが発生する．そこで，一般的なカメラで撮影する動画像の時刻補正を2周波の低価格・小型GNSS受信機・アンテナで往復運動を利用して，動画像とGNSSから作成した波形のピークを補正の目印に補正処理する手法を開発した．１時間程度の観測・撮影において，始まりと終わりに水平なレール上で往復運動させ，その波形の回帰分析結果を適用した結果，時刻補正誤差は，0.049sとなり，先行研究と同程度を示した．また，一般走行（40km/h，60km/h）で，概略設計で求められる地図情報レベルの1/1000地形図と1/2...

INTRODUCTION The aim of the present study was to evaluate the cutting efficiency of 2 new reciprocating instruments, Reciproc and WaveOne. METHODS Twenty-four new Reciproc R25 and 24 new WaveOne Primary files were activated by using a torque-controlled motor (Silver Reciproc) and divided into 4 groups (n = 12): group 1, Reciproc activated by Reciproc ALL program; group 2, Reciproc activated b...

The purpose of this study was to evaluate the presence of dentinal defects after root canal preparation with hand instruments and two different reciprocating instruments. Sixty freshly extracted mandibular incisor teeth were selected for this in vitro study. On the basis of root length, mesiodistal and buccolingual dimensions, the teeth were allocated into three identical experimental groups (n...

The design of a motion control system for a powered reciprocating gait orthosis is considered. Models for the orthosis are obtained using least squares identification. The control system design is based on pole-placement techniques and a restricted Youla parametrization of the controller. Experimental results are included.

As compared with continuous rotary systems, reciprocating motion is believed to increase the fatigue resistance of NiTi instruments. We compared the cyclic fatigue and torsional resistance of reciprocating single-file systems and continuous rotary instrumentation systems in simulated root canals. Eighty instruments from the ProTaper Universal, WaveOne, MTwo, and Reciproc systems (n = 20) were s...

In order to solve the problem of reciprocating motion in no beam supported mining machines, putting energy saving as a starting point in Coal Bed Methane (CBM) exploitation, this paper designs a completely non-circular gear automatic reversing vertical drainage machine based on the theory of non-circular gear transmission. In the field of CBM exploitation, the use of non-circular gears is an at...

A synthesis of the COMEZ spatial knitting mechanism has been developed to convert rotational motion around a moving axle in reciprocating motion. The done extremely remote positions.
