Aluminum cellular structures have been fabricated by combining a two-dimensional [0◦/90◦]2 arrangement of square Al 6061-T6 alloy tubes with orthogonal tubes inserted in the out-of-plane direction. By varying the tube wall thickness, the resulting three-dimensional cellular structures had relative densities between 11 and 43%. The dynamic compressive response of the three-dimensional cellular s...

Extracranial involvement of the recurrent laryngeal nerve and the hypoglossal nerve is known as Tapia's syndrome. Ipsilateral paralysis of the vocal cord and tongue is present. Lesion of these nerves may be a rare complication of airway management. Herein, a case of Tapia's Syndrome complicating transoral intubation during general anaesthesia in a rhinoplasty operation, together with a review o...

We proposed a local one-sided rubber bulging method of metal tubes to evaluate various strain paths at an aimed portion and measured the forming limit strains place occurrence necking under biaxial deformation. Using this method, since is used give pressure from inner side tube, no sealing mechanisms were necessary unlike during hydraulic bulging. An opening was prepared in front die locally bu...

Compression in the program space is of high importance in Artificial General Intelligence [Sol64, Hut07]. Since maximal data compression in the general sense is not possible to achieve [Sol64], it is necessary to use approximate algorithms, like AIXIt,l [Hut07]. This paper introduces a system that is able to compress data locally and iteratively, in a relational description language. The system...

Recently, there have been a lot of earthquakes in Japan. It is necessary to promote seismic isolation devices for buildings. The devices have been hardly diffused in attached houses, because the devices are very expensive. We should develop a low-cost seismic isolation device for detached houses. We suggested a new seismic isolation device which uses a two-layer circular tube as a unit. If hyst...

a r t i c l e i n f o Keywords: Concrete-filled steel tube (CFST) Confinement effect Fuzzy logic Modified learning from example (MLFE) Axial load capacity A circular concrete-filled steel tube (CFST) has several advantages compared with the conventional reinforced concrete member or hollow steel tube, since the tri-axial state of compression of the concrete infill increases its strength and str...

Background: Insertion of an external ventricular drain (EVD) is an important neurosurgical technique. There is a minor risk of misplacement, and complications including infections or hemorrhages have been reported. Transient neurological complications are, however, very rare, especially when EVD is placed under endoscope assistance. We report a case of unilateral transient oculomotor palsy afte...

Heat transfer during compression of air in a long, thin tube is studied by CFD. The tube represents one of the many in a honeycomb geometry inserted in a liquid piston air compressor to minimize temperature rise. A dimensionless number for the heat flow rate that includes the changing heat transfer area between the tube wall and air during compression is used. From the CFD results, alinear rela...
