Semantic segmentation of assembly images is to recognize the assembled parts and find wrong operations. However, training supervised semantic requires a large amount labeled data, which time-consuming laborious. Moreover, sizes mechanical assemblies are not uniform, leading low accuracy small-target objects. This study proposes an adversarial learning network for semi-supervised (AdvSemiSeg-MA)...

The Imaging X-ray Polarimetry Explorer, a NASA small explorer mission, will be the first mission dedicated to x-ray polarimetry. payload consists of three identical telescopes, each comprising mirror module assembly (MMA) with polarization-sensitive detector at its focus. We describe all aspects MMA, from initial optical and mechanical design considerations meet program requirements through she...

Herein, the conventional and unconventional hydrogen bonding potential of adenine in APA for double zipper helical assembly of deoxyoligonucleotides is demonstrated under ambient conditions. The quantum mechanical calculations supported the formation of hybrid DNA ensembles.

This paper presents the contimioiis wor/( on a previous project on vision-based hand interaction design. The original worJ< developed a vision-based approach of bare-hand-based posture recognition and motion tracking. This paper further investigates its application in virtual assembly. The accuracy and robustness of the developed approach enable product engineers to perform assembly operations ...

This paper presents a study to evaluate the mechanical properties of commercially available GRP composite fasteners for the fairing band assembly components of the hull mounted sonar domes on Canadian frigates. The study was undertaken as part of an effort to develop an all-composite fairing band assembly for a stainless steel sonar dome, to eliminate corrosion problems that occur with the use ...

This paper presents the continuous work on a previous project on vision-based hand interaction design. The original work developed a vision-based approach of bare-hand-based posture recognition and motion tracking. This paper further investigates its application in virtual assembly. The accuracy and robustness of the developed approach enable product engineers to perform assembly operations whi...

VARIATION SIMULATION OF FIXTURED ASSEMBLY PROCESSES FOR COMPLIANT STRUCTURES USING PIECEWISE-LINEAR ANALYSIS Michael Leon Stewart Department of Mechanical Engineering Master of Science While variation analysis methods for compliant assemblies are not new, little has been done to include the effects of multi-step, fixtured assembly processes. This thesis introduces a new method to statistically ...
